Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Graña y Montero S.A.A. and its subsidiaries

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated statements of financial position of Graña y Montero S.A.A. and its subsidiaries (the Company)
as of December 31, 2015 and 2016, the related consolidated statements of operations, comprehensive loss, changes in equity and cash flows for each of the years then ended, and the related notes. In our opinion, the financial statements present
fairly, in all material respects, the financial position of the Company as of December 31, 2015 and 2016, and the results of their operations and their cash flows for each of the years then ended, in conformity with International Financial
Reporting Standards as issued by the International Accounting Standards Board. Also, in our opinion, the Company did not maintain, in all material respects, effective internal control over financial reporting as of December 31, 2015 and 2016,
based on criteria established in Internal ControlIntegrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) because the following material weaknesses in internal control over
financial reporting existed as of those dates:



|- | Lack of a formally established and documented process for enterprise and fraud risk management.
|- | -----------------------------------------------------------------------------------------------



|- | Deficiencies in the design and operational effectiveness of controls over segregation of duties to help ensure that personnel with potential conflicts were not involved in incompatible activities.
|- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|- | Deficiencies in the design and operational effectiveness of the controls established in the accounting closing process with respect to the review of the consolidated and separate financial statements, including controls
over the review, approval and documentation related to journal entries.
|- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|- | Deficiencies in the design and operational effectiveness of controls established with respect to the recognition of revenue and determination of related estimates, including construction contract revenues and contingent
revenues, and the accounting for inventory.
|- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|- | Deficiencies in the design of controls over the timely accounting for signed contracts.
|- | ---------------------------------------------------------------------------------------



|- | Deficiencies in design and operational effectiveness of the controls over the review and approval of the valuation of acquired assets and liabilities as part of a step acquisition.
|- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|- | Lack of adequate supervision, monitoring and follow-up by the Audit Committee regarding the role of the Internal Audit Department.
|- | ----------------------------------------------------------------------------------------------------------------------------------



|- | Deficiencies in operational effectiveness of controls over SOX compliance.
|- | --------------------------------------------------------------------------

A material weakness is a
deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a
timely basis. The material weaknesses referred to above are described in Management Report on Internal Control over Financial Reporting appearing under Item 15. We considered these material weaknesses in determining the nature, timing, and extent of
audit tests applied in our audits of the 2015 and 2016 consolidated financial statements, and our opinion regarding the effectiveness of the Companys internal control over financial reporting does not affect our opinion on those consolidated
financial statements.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and
procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management
and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Emphasis of Certain Matters

As discussed in Note 1 to the financial statements, Peruvian prosecutors included three former executives of the Company in an investigation for the alleged
crimes of collusion and money laundering, and included Graña y Montero S.A.A and GyM S.A. as subjects of investigation and as third parties responsible on a civil basis. The Note also describes the results of an independent investigation and
estimates that the cases will be resolved in a manner favorable to their interests. We are not able to anticipate the final result of those undertakings and the possible contingencies which may arise.

As discussed in Note 2.30 to the consolidated financial statements, the Company made adjustments to the consolidated financial statements as of
December 31, 2015, which were presented in the previous Form 20-F. These adjustments consisted of reversals of estimates of work in progress and impairments of accounts receivable for S/
44.7 million, as well as corrections in the recording of goodwill for S/ 14.7 million, reversal of deferred tax asset for S/ 23.4 million and other items for S/ 3.3 million.

Basis for Opinion

The Companys management
is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the Managements Report on
Internal Control over Financial Reporting referred to above. Our responsibility is to express opinions on these financial statements and on the Companys internal control over financial reporting based on our audits.

We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the
amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our
audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating
effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

April 30, 2015

To Graña y Montero S.A.A. Board of
Directors and Shareholders:

In our opinion, the consolidated statements of income, of comprehensive income, of changes in equity and of cash flow for the
year ended December 31, 2014 present fairly, in all material respects, the results of operations and cash flows of Graña y Montero S.A.A. and its subsidiaries for the year ended December 31, 2014, in conformity with International
Financial Reporting Standards as issued by the International Accounting Standards Board. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements
based on our audit. We conducted our audit of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting
principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

GRAÑA Y MONTERO S.A.A. AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2014, 2015 AND 2016



|1 | GENERAL INFORMATION
|- | -------------------



| | a) | Incorporation and operations
| | -- | ----------------------------

Graña y Montero S.A.A. (hereinafter the Company) was
established in Peru on August 12, 1996 as a result of the equity spin-off of Inversiones GyM S.A. (formerly Graña y Montero S.A.). The Companys legal address is Av. Paseo de la
República 4675, Surquillo Lima, Peru and is listed on the Lima Stock Exchange and the New York Stock Exchange (NYSE).

The Company
is the parent of the Graña y Montero Group (hereinafter the Group, which includes the Company and subsidiaries) and it is mainly engaged in holding investments in different Group companies. Additionally, the Company provides services of
general management, financial management, commercial management, legal advisory and human resources management to the Group companies; it is also engaged in leasing offices to the Group companies.

The Group is a conglomerate of companies with operations including different business activities, the most significant are engineering and
construction, infrastructure (public concession ownership and operation), real estate businesses and services. See details of operating segments in Note 7.



| | b) | Authorization for issue of the financial statements
| | -- | ---------------------------------------------------

The consolidated financial statements for
the year ended December 31, 2016 were prepared and issued with Management and Board of Directors authorization on May 15, 2018 and will be submitted for consideration and approval at the General Shareholders Meeting. Management
expects that the consolidated financial statements as of December 31, 2016 will be approved with no changes.



| | c) | Current situation of the Company
| | -- | --------------------------------



| | i) | Legal Status
| | -- | ------------



| | (A) | Projects conducted in association with Odebrecht
| | --- | ------------------------------------------------

Our company participated as minority
shareholder in certain entities that developed six infrastructure projects in Peru with Odebrecht. In 2016, Odebrecht entered into a Plea Agreement with the authorities of the United States Department of Justice and the Office of the District
Attorney for the Eastern District of New York by which it admitted the commission of corrupt acts in connection to two these projects (sections 2 and 3 of the Interoceánica Sur highway (IIRSA Sur) and the project to construct the
Tren Eléctrico). As a consequence of this agreement, the Peruvian authorities initiated investigations.



| | (I) | IIRSA Sur
| | --- | ---------

With respect to the investigations conducted in relation to IIRSA Sur, the Public
Prosecutors Office included the former Chairman of the Board of Directors, for bribery; a former Director, and a former executive of the company, for money laundering.

Subsequently, Graña and Montero S.A.A. and GyM S.A. were incorporated as subjects investigated in the case described above. The
companies have appealed this judgment and the appeals are pending resolution by the Superior Court.



F-10

(All amounts expressed in thousands of S/ unless otherwise stated)



In addition, the Peruvian authorities has requested incorporation of Graña y Montero
S.A.A. as third party responsible on a civil basis and the Company has filed an opposition to the governments motion. Oral arguments will be made before the court on a hearing that is yet to be scheduled.

The Company believes that it has a solid defense and that therefore, the case would be resolved in its favor.



| | (II) | Electric Train
| | ---- | --------------

The Peruvian authorities also requested to incorporate GyM S.A. as a third
party responsible on a civil basis in the case related to the project to construct the electric train. The Company has filed an opposition. Oral arguments will be made before the court on a hearing that is yet to be scheduled.

The Company believes that it has a solid defense and that therefore, the case would be resolved in its favor.



| | (B) | The Constructor Club
| | --- | --------------------

On July 11, 2017, Commision de libre competence of
Indecopi initiated an investigation against several construction companies, including GyM S.A., about the existence of an alleged cartel called the Constructor Club, gathering information from the Company. Throughout the investigation,
the Company has provided to the Indecopi with all the information requested.

The Companys former commercial manager is under a
criminal investigation, as well as other individuals related to other construction companies. However, the Company is not included in this case.

To the date the result of the case described is uncertain because it is in the preliminary phase and depends on the action of the third parties
that have been included in it, However, management believes that the contingency to which the Company is exposed should not have a significant financial impact due to the lack of links I has with the alleged facts.



| | (C) | Anticorruption Law application to the Company
| | --- | ---------------------------------------------

Law 30737 and its regulation issued by Supreme
Decree 096-2018-EF has mitigated the Companys exposure to the cases described in sub sections (A) and (B) above. These rules set clear guidelines to estimate
the potential compensation that would be paid by the Company in the improbable case that it would be convicted. Furthermore, these rules have significantly reduced the uncertainty derived from the legal proceedings, by among other things, preventing
the imposition of liens or attachments of assets that would impair the ability of the Company to operate.

The benefits of the mentioned
rules are subject to the fullfilment of the following obligations:



| |  |  | The obligation to set up a trust that will guarantee any potential payment obligation of an eventual civil compensation and the interests in favor of the Peruvian State;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The obligation not to transfer funds abroad without the prior consent of the Ministry of Justice;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | The implementation of a compliance program; and
| | - |  | -----------------------------------------------



| |  |  | The obligation to disclose information to the authorities and to collaborate in the investigation.
| | - |  | --------------------------------------------------------------------------------------------------

The Company has designed a robust compliance program which is currently under implementation. In addition, it fully cooperates with the
authorities in its investigations of the alleged facts. It is also engaged in preliminary works necessary to set up the trust while it receives from the authorities the amount of the trust. Management estimated that it would need to assign to the
trust assets worth approximately USD 41 million and that its potential liability should not exceed USD 51 million.

| | ii) | Independent Investigation related to Company business with Odebrecht S.A.
| | --- | -------------------------------------------------------------------------

On
January 9, 2017, the Company Board of Directors approved a plan to conduct an independent investigation related to six projects executed in association with Odebrecht.

On March 30, 2018, the Board of Directors created a Risk, Compliance and Sustainability Committee who was in charge of the oversight of
the investigation independent from management. The investigation was entrusted to Simpson, Thatcher and Bartlett that reported exclusively to the Risk, Compliance and Sustainability Committee to preserve its independence.

The independent investigation concluded on November 2, 2017, and found no evidence that the Group or any of its former or current
directors or executives had intentionally or knowingly participated in acts of corruption related to the 6 projects developed in association with Odebrecht.



|2 | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
|- | ------------------------------------------

The principal accounting policies applied in
the preparation of these consolidated financial statements are set out below. These policies have been consistently applied in all the years presented, unless otherwise stated.



|2.1 | Basis of preparation
|--- | --------------------

The consolidated financial statements of the Company and its
subsidiaries have been prepared in accordance with International Financial Reporting Standards (IFRS) and interpretations issued by the IFRS Interpretations Committee (IFRIC) applicable to companies reporting under IFRS. The financial statements
comply with IFRS as issued by the IASB in force as of 31 December, 2015 and 2016 respectively.

The consolidated financial statements
have been prepared under the historical cost convention, except for derivative financial instruments, financial assets at fair value through profit and loss, available-for-sale financial assets measured at
fair value. The financial statements are presented in thousands of Peruvian Soles, unless otherwise stated.

The preparation of the
consolidated financial statements in conformity with IFRS requires Management to make estimates and assumptions in the process of applying the Groups accounting policies. The areas involving a higher degree of judgment or complexity, or areas
where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note 5.



|2.2 | Consolidation of financial statements
|--- | -------------------------------------



| | a) | Subsidiaries
| | -- | ------------

Subsidiaries are entities over which the Company has control. Subsidiaries are
fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases.

The Group applies the acquisition method to account for business combinations. Identifiable assets acquired, liabilities and contingent
liabilities assumed in a business combination are measured initially at their fair values at the acquisition date.



F-12



---

(All amounts expressed in thousands of S/ unless otherwise stated)



The Group evaluates measurement of the
non-controlling interest on an acquisition-by-acquisition basis. At December 31, 2015 and 2016, the measurement of the non-controlling interest in the Groups acquisitions was made at the non-controlling interests proportionate share of the recognized amounts of the acquirees
identifiable net assets.

Business acquisition-related costs are expensed as incurred.

Any contingent consideration assumed by the Group with the selling party is recognized at fair value at the acquisition date. Subsequent
changes to the fair value of the contingent consideration is recognized in accordance with IAS 39 as profit or loss.

Goodwill is initially
measured as the excess of the acquisition cost, the fair value at the acquisition date of any interest previously acquired plus the fair value of the non-controlling interest, over the net identifiable assets
acquired and liabilities and contingent liabilities assumed. If the acquisition cost is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized in profit or loss at the time of acquisition.

For consolidating subsidiaries, balances, income and expenses from transactions between Group companies are eliminated. Profits and losses
resulting from inter-company transactions that are recognized as assets are also eliminated. If required, accounting policies of subsidiaries are changed where necessary to ensure consistency with the policies adopted by the Group.



| | b) | Changes in ownership interests in subsidiaries without change of control
| | -- | ------------------------------------------------------------------------

Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions, in other words as transactions with owners in their capacity as owners. The difference between fair value of
any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interest, are also recorded
in equity at the time of disposal.



| | c) | Disposal of subsidiaries
| | -- | ------------------------

When the Group ceases to have control over a subsidiary, any retained
interest in the entity is re-measured at its fair value at the date when control is lost, with the change in carrying amount recognized in profit or loss at such date. The fair value is the initial carrying
amount for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for
as if the Group had directly disposed of the related assets or liabilities. This may mean that the amount previously recognized in other comprehensive income is reclassified to profit or loss.



| | d) | Joint arrangements
| | -- | ------------------

Contracts in which the Group and one or more of the contracting parties
have joint control on the relevant joint activities are called joint arrangements.

Investments in joint arrangements are classified as
either joint operations or joint ventures depending on the contractual rights and obligations of each investor. The Group has assessed the nature of its joint arrangements and determined them to be both joint ventures as well as joint operations.

Joint ventures are accounted for using the equity method. Under the equity method of accounting, interests in joint ventures are initially
recognized at cost and adjusted thereafter to recognize the Groups share of the post-acquisition profits or losses and movements in the comprehensive income statement.



F-13



---

(All amounts expressed in thousands of S/ unless otherwise stated)



The Group assesses on an annual basis whether there is any objective evidence that the
investment in the joint ventures and associate is impaired. If this is the case, the Group calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value and recognizes the impairment
loss in share of profit or loss in associates and joint ventures under the equity method of accounting in the income statement.

Joint operations are joint arrangements whereby the parties that have joint control of the arrangement, have rights over the assets, and
obligations for the liabilities, relating to the arrangement. Each party recognizes its assets, liabilities, revenue and cost and its share of any asset or liability jointly held and on any revenue or cost arisen from the joint operation.

In the Group, joint operations mainly relate to consortiums (entities without legal personality) created exclusively for the development of a
construction contract. Considering that the only objective of the consortium is to develop a specific construction contract, all costs and revenue are included within revenue from construction activities and cost of construction activities,
respectively.



| | e) | Associates
| | -- | ----------

Associates are all entities over which the Group has significant influence but not
control, generally accompanying a holding of between 20% and 50% of the voting rights. Investments in associates are accounted for using the equity method of accounting (see section d above).

Profits and losses resulting from transactions between the Group and its associates are recognized in the Groups financial statements
only to the extent of unrelated investors interests in the associates. Unrealized losses are eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates are changed where
necessary to ensure consistency with the policies adopted by the Group.

Impairment losses are measured and recorded in accordance with
section d) above.



|2.3 | Segment reporting
|--- | -----------------

Operating segments are reported in a consistent manner with internal
reporting provided to Management of the Group.

If an entity changes the structure of its internal organization in a manner that causes the
composition of its reportable segments to change, the Group restates the information for earlier periods unless the information is not available.



|2.4 | Foreign currency translation
|--- | ----------------------------



| | a) | Functional and presentation currency
| | -- | ------------------------------------

The consolidated financial statements are presented in
Peruvian Soles, which is the Companys functional currency and the Groups presentation currency. All subsidiaries, joint arrangements and associates use the Peruvian Sol as their functional currency, except for foreign entities, for which
the functional currency is the currency of the country in which they operate.



| | b) | Transactions and balances
| | -- | -------------------------

Foreign currency transactions are translated into the functional
currency using the exchange rates at the date of the transactions or valuation when items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions are recognized in
the consolidated income statement, except when deferred in other comprehensive income.

Exchange differences arising on loans from the
Company to its subsidiaries in foreign currencies are recognized in the separate financial statements of the Parent and individual financial statements of the subsidiaries. In the consolidated financial statements, such exchange differences are
recognized in other comprehensive income and are subsequently re-classified in the income statement on the disposal of the subsidiary or debt repayment, to the extent such loans qualify as part of the
net investment in a foreign operation.



F-14



---

(All amounts expressed in thousands of S/ unless otherwise stated)



Foreign exchange gains and losses of all monetary items are included in the income statement
within financial income or expense.



| | c) | Group companies
| | -- | ---------------

The results and financial position of all the Group entities (none of which
has the currency of a hyper-inflationary economy) that have a functional currency different from the presentation currency of the Group are translated into the presentation currency as follows:



| | i) | Assets and liabilities for each statement of financial position presented are translated using the closing exchange rate prevailing at the date of the consolidated statement of financial position;
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ii) | income and expenses for each income statement are translated at the average exchange rate (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates,
in which case income and expenses are translated using the exchange rate on the date of the transaction);
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | iii) | capital is translated by using the historical exchange rate for each capital contribution made; and
| | ---- | ---------------------------------------------------------------------------------------------------



| | iv) | all exchange differences are recognized as separate components in other comprehensive income (loss), within foreign currency translations adjustment.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------

Goodwill and fair value adjustments arising from the acquisition of a foreign entity are treated as assets and liabilities of the foreign
entity and are translated at the closing exchange rate. Exchange differences are recognized in other comprehensive income.



|2.5 | Public services concession agreements
|--- | -------------------------------------

Concession agreements signed between the Group
and the Peruvian Government entitle the Group, as a Concessionaire, to assume obligations for the construction or improvement of infrastructure and which qualify as public service concessions are accounted as defined by IFRIC 12, Service
Concession Arrangements. The consideration to be received from the Government for the services of constructing or improving public infrastructure is recognized as a financial asset or as an intangible asset (bifurcated model), as set forth
below.



| | The | Group manages three types of concessions, for which accounting treatment is as follows:
| | --- | ---------------------------------------------------------------------------------------



| | a) | Recognizes a financial asset to the extent that it has a contractual right to receive cash or other financial assets either because the Government secures the payment of specified or determinable amounts or because the
Government will cover any difference arising from the amounts actually received from public service users in relation with the specified or determinable amounts. These financial assets are recognized initially at fair value and subsequently at
amortized cost (the financial model).
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b) | Recognizes an intangible asset to the extent that the service agreement grants the Group a contractual right to charge users of the public service. The resulting intangible asset is measured at cost and is amortized as
described in Note 2.15 (intangible asset model).
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c) | Recognizes a financial asset and an intangible asset when the Group recovers its investment partially by a financial asset and partially by an intangible asset (the bifurcated model).
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.6 | Cash and cash equivalents
|--- | -------------------------

In the consolidated statements of financial position and cash
flows, cash and cash equivalents include cash on hand, on-demand bank deposits, other highly liquid investments with original maturities of three months or less and bank overdrafts. In the consolidated
statement of financial position, bank overdrafts are included in the balance of financial obligations as current liabilities.



F-15



---

(All amounts expressed in thousands of S/ unless otherwise stated)



|2.7 | Financial assets
|--- | ----------------



|2.7.1 | Classification
|----- | --------------

The Group classifies its financial assets in the following categories:
financial assets at fair value through profit or loss, financial assets held-to-maturity, loans and account receivables and financial assets available-for-sale. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at
initial recognition.

As of the date of the consolidated financial statements, the Group has classified its financial assets in the
following three categories:



| | a) | Financial assets at fair value through profit or loss
| | -- | -----------------------------------------------------

Financial assets at fair value through
profit or loss are non-derivatives that are designated by the Group as at fair value upon initial recognition and are
held-for-trading. They are included in current assets in the consolidated statement of financial position. The derivative financial instruments policy is included at
Note 2.9.



| | b) | Loans and accounts receivable
| | -- | -----------------------------

Loans and receivables are
non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for those whose maturity is greater than twelve months
after the date of the consolidated financial statements. These are classified as non-current assets on the consolidated financial position. The Groups loans and receivables comprise trade accounts
receivables, accounts receivable from related parties, other accounts receivable, unbilled work in progress and cash and cash equivalents.



| | c) | Available-for-sale financial assets
| | -- | -----------------------------------

Available-for-sale financial assets are non-derivatives that are either designated in this category or not classified in any of the other categories. They are included in non-current assets as Other Financial
Assets unless Management intends to dispose them within 12 months of the date of the statement of financial position.



|2.7.2 | Recognition and measurement
|----- | ---------------------------

Regular purchases and sales of financial assets are
recognized on the trade-date, the date on which the Group commits to purchase or sell the asset. Investments are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss.
Financial assets are derecognized when the rights to receive cash flows from the investments have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership. Available-for-sale financial assets are subsequently carried at fair value. Loans and receivables are subsequently carried at amortized cost using the effective interest method.

Gains or losses arising from changes in the fair value of the financial assets at fair value through profit or loss category are
presented in profit or loss within Other income and expenses, net in the period in which they arise. Dividend income from financial assets at fair value through profit or loss is recognized in the income statement as part of Other
income and expenses, net when the Groups right to receive payments is established.



F-16



---

(All amounts expressed in thousands of S/ unless otherwise stated)



Changes in the fair value of monetary securities classified as available for sale are
recognized in other comprehensive income. When a financial asset classified as available for sale is sold or impaired, the accumulated fair value adjustments recognized in equity are reclassified to profit or loss. Dividends on available-for-sale equity instruments are recognized in the income statement as part of Other income and expenses, net when the Groups right to receive
payments is established.



|2.8 | Impairment of financial assets
|--- | ------------------------------



| | a) | Assets carried at amortized cost
| | -- | --------------------------------

At the end of each reporting period the Group assesses
whether there is objective evidence that a financial asset or a group of financial assets is impaired. If a financial asset or a group of financial assets is impaired, the impairment losses are recognized only if there is objective evidence of
impairment as a result of one or more events that occurred after the initial recognition of the asset (a loss event) and that loss event (or events) has an impact on the estimated future cash flows of the financial asset or group of
financial assets that can be reliably estimated.

For the loans and receivables category, the amount of any loss is measured as the
difference between the assets carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial assets original effective interest rate. The
carrying amount of the asset is reduced and the amount of the loss is recognized in the statement of comprehensive income. If a loan or an account receivable has a variable interest rate, the discount rate for measuring any impairment loss is the
current effective interest rate determined under the contract. As a practical expedient, the Group may measure impairment on the basis of an instruments fair value using an observable market price.



| | b) | Assets classified as available-for-sale -
| | -- | -----------------------------------------

The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or a group of financial
assets classified as available-for-sale is impaired.

For
equity investments, a significant or prolonged decline in the fair value of the security below its cost is also evidence that the assets are impaired. If any such evidence exists for
available-for-sale financial assets, the cumulative lossmeasured as the difference between the acquisition cost and the current fair value, less any impairment
loss on that financial asset previously recognized in profit or lossis removed from equity and recognized in profit or loss. Impairment losses recognized in the income statement on equity instruments are not reversed through the income
statement.



|2.9 | Derivative financial instruments and hedging activities
|--- | -------------------------------------------------------

Derivatives are initially
recognized at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value at the end of each reporting period. The method of recognizing the resulting gain
or loss depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged.

The Group
designates certain derivatives as hedges of a particular risk associated with a recognized asset or liability (fair value hedge) or a highly probable forecast transaction (cash flow hedge). Derivatives are initially recognized at fair value on the
date of subscription of the contract and are subsequently recognized at their fair value. The method to recognize the gain or loss resulting from changes in the fair values of the derivatives depends on the nature of the item being covered.

The Group documents, at the inception of the transaction, the relationship between hedging instruments and hedged items, as well as its risk
management objectives and strategy for undertaking various hedging transactions. The Group also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly
effective in offsetting changes in fair values or cash flows of hedged items.



F-17



---

(All amounts expressed in thousands of S/ unless otherwise stated)



The fair values of various derivative instruments used for hedging purposes and changes in
the account reserves for hedging in equity are disclosed in Note 8. The full fair value of a hedging derivative is classified as a non-current asset or liability when the remaining maturity period of the
hedged item is more than 12 months and as a current asset or liability when the remaining maturity period of the hedged item is less than 12 months. Trading derivatives are classified as a current asset or liability.

Cash flow hedge

The effective
portion of changes in the fair value of derivatives that are designated and qualify as fair value hedges is recognized as other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in the income
statement.

Amounts accumulated in equity are reclassified to profit or loss in the periods when the hedged item affects profit or loss
(for example, when the forecasted sale that is hedged takes place).

The gain or loss relating to the effective portion of interest rate
swaps hedging variable rate borrowings is recognized in the income statement as Financial income or Financial expenses.

However, when the forecasted transaction that is hedged results in the recognition of a non-financial
asset (for example, inventory or fixed assets), the gains or losses previously deferred in equity are transferred from equity and are included in the initial measurement of the cost of the non-financial asset.
The deferred amounts are ultimately recognized in cost of goods sold in the case of inventory or in depreciation in the case of fixed assets.

When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss
existing in equity at that time remains in equity and is recognized when the forecasted transaction is ultimately recognized in the income statement. When a forecasted transaction is no longer expected to occur, the cumulative gain or loss that was
reported in equity is immediately transferred to the income statement within other income and expenses, net.



|2.10 | Trade receivables
|---- | -----------------

Trade receivables are amounts due from customers for goods or
services sold by the Companys subsidiaries. If collection is expected in one year or less, they are classified as current assets. If not, they are presented as non-current assets.

Trade receivables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method, less
any provision for impairment, except for receivables of less than one year that are stated at nominal amount which is similar to their fair values since they are short term.



|2.11 | Unbilled work in progress
|---- | -------------------------

Unbilled work in progress comprises the estimation made by
the Management of the Engineering and Construction segment related to the unbilled rights receivable for services rendered and not yet approved by the client (valuation based on the percentage of completion).

It also includes the balance of work in progress costs incurred that relates to future activities of the construction contracts and the
constructions phase in concessions (see Note 2.25 for detail on Revenue from construction and concession activities).

Changes in estimates
of contract revenues and costs can increase or decrease the estimated margin. When a change in the estimate is known, the cumulative impact of the change is recorded in the period in which it is known based on the progress made.



F-18

(All amounts expressed in thousands of S/ unless otherwise stated)



|2.12 | Inventories
|---- | -----------

Inventory mainly includes land, work in progress and finished properties
which are assigned to the real- estate activity. Land intended to carry out real estate projects is recognized at acquisition cost. Work in progress and finished properties comprise design costs, material, labor costs, financial costs (directly
attributable to the acquisition, construction and production of qualified assets), other indirect costs and general expenses related to the construction.

Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses. The Company
reviews annually whether inventories have been impaired identifying three groups of inventories to measure their net realizable value: i) the first group consists of land bought for future real estate projects which are compared to their net
appraisal value; if the acquisition value is higher, a provision of impairment is made; ii) the second group consists of land under construction, impairment is measured based on cost projections; if these costs are higher than selling prices of each
real estate unit, a provision is made for impairment; and iii) the third group comprises completed real estate units; these inventory items are compared to the selling prices less selling expenses; if these selling expenses are higher, a provision
for impairment is made. For the reductions in the carrying amount of these inventories to their net realizable value, a provision is made for impairment of inventories with a charge to profit or loss for the year in which those reductions occur.

It also includes material used in the construction activity. Goods and supplies correspond to goods that the Group trades as part of its
IT segment. Materials and supplies used in construction activities and IT equipment are determined under the weighted average cost method. Materials and other supplies are not written down below cost if the finished products in which they will be
incorporated are expected to generate margin.

|2.13 | Investment properties
|---- | ---------------------

Investment properties are shown at cost less accumulated
depreciation and impairment losses, if any. Subsequent costs attributable to investment properties are capitalized only if it is probable that future economic benefits will flow to the Company and the cost of these assets can be measured reliably;
if not, they are recognized as expenses when incurred.

Repair and maintenance expenses are recognized in profit and loss when they are
incurred. If the propertys carrying amount is greater than its estimated recoverable amount, an adjustment to reduce the carrying amount to the recoverable amount is recognized.

Depreciation is determined at rates calculated to write off cost, less estimated residual value, of each asset on a straight line basis over
its estimated useful life. The estimated useful lives of those properties range from 5 to 33 years.

The investment property held by the
Group consists of two Shopping Centers owned by subsidiary Viva GyM S.A. Fair value is estimated to be US$29.5 million, equivalent to S/99 million, at December 31, 2016 (US$16.7 million, equivalent to S/58 million, at
December 31, 2015). The sales stores of these properties have been leased as an operating lease with third parties.



|2.14 | Property, plant and equipment
|---- | -----------------------------

Property, plant and equipment are stated at historical
cost less accumulated depreciation and impairment losses, if any. Historical cost includes expenditure that is directly attributable to the acquisition of these items.

Subsequent costs are included in the assets carrying amount or are recognized as a separate asset, as appropriate, only when it is
probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. Repairs and maintenance expense are charged to the income statement during the financial period in which they
are incurred.

Assets under construction are capitalized as a separate component. At their completion, the cost of such assets is
transferred to their definitive category.

Replacement units are major spare parts in which depreciation starts when the units are
installed for use within the related asset.

Depreciation of machinery and equipment and vehicles recognized as Major equipment
are depreciated based on their hours of use. Under this method, the total number of work hours that machinery and equipment is capable to produce is estimated and a charge per hour is determined. The depreciation of other assets that do not qualify
as Major equipment is calculated under the straight-line method to allocate their cost less their residual values over their estimated useful lives, as follows:



|                         |  |       |                  | 
|------------------------ |  | ----- | ---------------- | 
|                         |  | Years |                 
|Buildings and facilities |  |       | Between 3 and 50 | 
|Machinery and equipment  |  |       | Between 4 and 10 | 
|Vehicles                 |  |       | Between 2 and 10 | 
|Furniture and fixtures   |  |       | Between 2 and 10 | 
|Other equipment          |  |       | Between 2 and 10 | 



F-20



---

(All amounts expressed in thousands of S/ unless otherwise stated)



Residual values and useful lives are reviewed and adjusted as appropriate at each date of the
statement of financial position. Gains and losses on disposals are recognized in Other income and expenses, net in the income statement. Regarding joint operations that carry out construction activities, the difference between the
proceeds from disposals of fixed assets and their carrying amount is shown within revenue from construction activities and cost of construction activities, respectively.



|2.15 | Intangible assets
|---- | -----------------



| | i) | Goodwill
| | -- | --------

Goodwill arises on the acquisition of subsidiaries and represents the excess of the
purchase consideration, the amount of any non-controlling interest and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the net identifiable assets
acquired. If the total of consideration transferred, non-controlling interest recognized and previously held interest measured at fair value is less than the fair value of the net assets of the subsidiary
acquired, in the case of a bargain purchase, the difference is recognized directly in the income statement.

Goodwill acquired in a
business combination is allocated to each cash-generating units (CGU), or group of CGUs, that is expected to benefit from the synergies of the combination. Goodwill is monitored at the operating segment level.

Goodwill impairment reviews are performed at least annually and when events or changes in circumstances indicate a potential impairment. Any
impairment is recognized immediately as an expense in item Other income and expenses, net and cannot be reversed later.



| | ii) | Trademarks
| | --- | ----------

Trademarks acquired separately are shown at historical cost. Trademarks acquired in
a business combination are recognized at fair value at the acquisition date. Management has determined that these trademarks have indefinite useful lives. These trademarks have a long trajectory (between 24 and 39 years) in each market and the Group
is committed to continue investing in the long-term to extend the period over which they are expected to continue to provide economic benefits.

Trademark impairment reviews are performed at least annually and when events or changes in circumstances indicate a potential impairment. Any
impairment is recognized immediately as an expense in item Other income and expenses, net and cannot be reversed later.



| | iii) | Concession rights
| | ---- | -----------------

The intangible asset consisting of the right to charge users for the
services related to service concessions agreements (Note 2.5 and Note 6.b) is initially recorded at the fair value of construction or improvement services. Before amortization is started, an impairment test is performed; it is amortized under the
straight-line method, from the date revenue starts using the lower of its estimated expected useful life or effective period of the concession agreement.



| | iv) | Contractual relationships with customers
| | --- | ----------------------------------------

Contractual relationships with customers are assets
resulting from business combinations that were initially recognized at fair value as determined based on the expected cash flows from those relations over an estimated period of time based on the time period those customers will remain as customers
of the Group (the estimation of useful life is based on the contract terms which fluctuate between 5 and 9 years). The useful life and the impairment of these assets are individually assessed.



F-21



---

(All amounts expressed in thousands of S/ unless otherwise stated)



| | v) | Cost of developing wells
| | -- | ------------------------

Costs incurred in preparing wells to extract hydrocarbons in Blocks
I, III, IV and V, located in Talara, are capitalized as part of intangible assets. These costs are amortized over the useful lives of the wells (10 years for Blocks III, IV and V and 9 years for Block I), when is less than the period of the service
agreement signed with Perupetro.



| | vi) | Internally generated software and development costs
| | --- | ---------------------------------------------------

Development costs that are directly
attributable to the design and testing of identifiable and unique software products controlled by the Group are recognized as intangible assets when the following criteria are met:



| |  |  | It is technically feasible to complete the software product so that it will be available for use;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | management intends to complete the software product and use or sell it;
| | - |  | -----------------------------------------------------------------------



| |  |  | there is an ability to use or sell the software product;
| | - |  | --------------------------------------------------------



| |  |  | it can be demonstrated how the software product will probably generate future economic benefits;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | technical, financial and other resources are available to complete the development and to use or sell the software product; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | software expense during its development can be reliably measured.
| | - |  | -----------------------------------------------------------------

Other development
expenditures that do not meet these criteria are expensed as incurred. Development costs previously recognized as an expense are not recognized as an asset in a subsequent period. Computer software development costs recognized as assets are
amortized over their estimated useful lives, which fluctuate between 2 to 8 years.



| | vii) | Rights of use of land
| | ---- | ---------------------

Refers rights maintained by the Promotora Larcomar subsidiary S.A.
Rights of use of land are stated at historical cost less amortization and any accumulated impairment losses. The useful life of this asset is based on the agreement signed (60 years) and the effective period may be extended if agreed to the parties.
Amortization will begin when it becomes ready for its intended use by Management.



|2.16 | Impairment of non-financial assets
|---- | ----------------------------------

Assets that
have an indefinite useful life are not subject to amortization and are subject to review annually for impairment. Assets that are subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the
carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the assets carrying amount exceeds its recoverable amount.



|2.17 | Trade payables
|---- | --------------

Trade payables are obligations to pay for goods or services that have
been acquired in the ordinary course of business. Accounts payable are classified as current liabilities if payment is due within one year or less (or in the normal operating cycle of the business if longer). If not, they are presented as non-current liabilities.

Accounts payable are initially recognized at their fair value and subsequently
are amortized at amortized cost using the effective interest method, except for accounts payable less than one year that are recorded at their nominal value that is similar to their fair value due to its expiration in the short term.



|2.18 | Other financial liabilities
|---- | ---------------------------

Correspond to loans and bonds issued by the Group, which
are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently carried at amortized cost; any difference between the cash received (net of transaction costs) and the redemption value is recognized in the
income statement over the period of the borrowings using the effective interest method.



F-22



---

(All amounts expressed in thousands of S/ unless otherwise stated)



Fees paid for entering into loan facilities are recognized as transaction costs of the loan
to the extent that it is probable that some or all of the facility will be drawn down. In this case, the fee is deferred until the draw-down occurs.



|2.19 | Borrowing costs
|---- | ---------------

Borrowing costs are recognized in the income statement in the period in
which they are incurred except for intangible assets and inventories (Note 18 and 15) in which the Group proceeds to capitalize borrowing costs.

General and specific borrowing costs directly attributable to acquisitions, construction or development of qualifying assets, which are assets
that necessarily take a substantial period of time (over 12 months) to get ready for their intended use or sale, are added to the cost of those assets, until assets are substantially ready for their intended use or sale. The Company suspends
capitalization of a qualifying asset during periods in which qualify asset development is interrupted .Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the
borrowing costs eligible for capitalization.



|2.20 | Current and deferred income tax
|---- | -------------------------------

Income tax expense comprises current and deferred tax.
Tax expense is recognized in the income statement, except to the extent that it relates to items recognized in other comprehensive income or equity, in which case, it is recognized in the statement of comprehensive income or directly in equity,
respectively.

The current income tax is calculated on the basis of the tax laws enacted or substantively enacted at the date of the
statement of financial position in the countries where the Company and its subsidiaries operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax
regulation is subject to interpretation. Management, where appropriate, establishes provisions on the basis of amounts expected to be paid to the tax authorities.

Deferred tax is recognized on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the
financial statements. However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill; deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a
transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantially enacted by
the balance sheet date and are expected to apply when the related deferred income tax asset is realized or is settled.

Deferred income tax
assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized. Deferred income tax is provided on temporary differences arising on investments in
subsidiaries and associates, except for deferred income tax liability where the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable
future.

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets
against current tax liabilities and when the deferred income tax assets and liabilities relate to income taxes levied by the same taxation authority.



F-23

(All amounts expressed in thousands of S/ unless otherwise stated)



|2.21 | Employee benefits
|---- | -----------------



| | a) | Profit sharing
| | -- | --------------

Peruvian entities of the Group recognize a liability and an expense for
statutory workers profit sharing under laws and regulations currently in force. Workers profit sharing is equivalent to 5% or 8% of the taxable income determined separately by each of the Groups Peruvian entities, according to the
income tax currently in force. The branch based in the Dominican Republic has a similar profit sharing scheme, with a rate of 10% on the taxable income. For Chile, workers profit sharing is a component of remuneration (equivalent to 4.75
minimum salary per year) rather than a percentage based on profits. In Colombia and Guyana no such benefits are paid to workers. In Bolivia workers profit sharing is equivalent to a one-month salary and
the total amount distributed cannot exceed 25% of companys profits determined under local regulations.



| | b) | Statutory bonuses
| | -- | -----------------

Entities of the Group recognize the expense and the related liability for
statutory bonuses based on applicable laws and regulations effective in Peru, Chile, Bolivia, Guyana and Colombia.



| | c) | Severance Compensation
| | -- | ----------------------

Employees severance payments for time of service of the Peruvian
Group staff comprise their indemnification rights, calculated in accordance with the regulations in force, which have to be deposited on bank accounts designated by workers in May and November each year. The compensation for time of service amounts
to one-months salary effective at the date of bank deposits. There is no such benefit in Chile and Guyana. The Group does not have any additional payment obligation once the annual deposits are made of
the amounts to which workers are entitled.



| | d) | Vacation leave
| | -- | --------------

Annual vacation leave is recognized on an accrual basis. Provision for the
estimated obligations of annual vacations is recognized at the date of the statement of financial position and it corresponds to one month for Peruvian employees and fifteen days for Dominican and Colombian employees per year. In Bolivia and Chile
vacation leave depends on seniority of a worker and ranges from fifteen to thirty days.



| | e) | Pension plans
| | -- | -------------

The subsidiary CAM has in place a pension plan scheme with its workers. These
commitments comprise both defined benefit and defined contribution plans. A defined benefit plan defines an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors such as age, years of service
and compensation.

The liability recognized in the statement of financial position with respect to the defined benefit pension plan is the
present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest
rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the related pension obligation. In countries where there is no deep market
in such bonds, the market rates on government bonds are used.

Re-measurements arising from
experience adjustments and changes in actuarial assumptions are charged or credited to equity in other comprehensive income in the period in which they arise.



F-24



---

(All amounts expressed in thousands of S/ unless otherwise stated)



| | f) | Restructuring Cost
| | -- | ------------------

Group companies recognize the liability and the expense for employees
severance indemnities when they are incurred. Under Peruvian laws, in the event of an arbitrary termination of a worker, the related indemnities equal an additional one-month salary and a half per each year
actually worked by the terminated worker.

Under Colombian laws, this type of indemnities is determined based on the salary. Under Chilean
laws, termination indemnities equal an additional 30-day salary per each year actually worked up to a maximum 330 days.



|2.22 | Other provisions
|---- | ----------------



| | a) | General
| | -- | -------

Provisions are recognized when the Group has a present legal or constructive
obligation as a result of past events; it is probable that an outflow of resources will be required to settle the obligation; and the amount has been reliably estimated. Provisions are reviewed at year - end. If the time value of money is
significant, provisions are discounted using a pre-tax rate that reflects, when applicable, the specific risks related to the liability. Reversal of the discount due to the passage of time results in the
obligation being recognized with a charge to the income statement as a financial expense. Provisions are not recognized for future operating losses.

Contingent obligations are disclosed for possible obligations that are not yet determined to be probable. Contingent assets are not recognized
and only disclosed if it is probable that future economic benefits will flow to the Company.

b) Provision for the closure of production
wells -

The subsidiary GMP recognizes a provision for the closure of operating units that correspond to the legal obligation to close oil
production wells once the production phase has been completed. At the initial date of recognition, the liability that arises from said obligation is measured at the amount of expected cash flow discounted to present value, the same amount is
simultaneously charged to the intangible account in the statement of financial position. Subsequently, the liability will increase in each period to reflect the financial cost considered in the initial measurement of the discount, and the
capitalized cost is depreciated based on the useful life of the related asset. When a liability is settled, the Groups entities will recognize any gain or loss that may arise. The fair value changes estimated for the initial obligation and
interest rates are recognized as an increase or decrease of the carrying amount of the obligation and related asset, any decrease in the provision, and any decrease of the asset that may exceed the carrying amount of said asset is immediately
recognized in the income statement.

If the review of the estimated obligation results in the need to increase the provision and,
accordingly, increase the carrying amount of the asset, the Groups entities will also take into consideration if said increase corresponds to an indicator that the asset has been impaired and, if so, impairment tests are carried out (Note
2.16).



|2.23 | Put option arrangement
|---- | ----------------------

The Group has written put options over the equity of its
subsidiary Morelco SAS (Note 33 b) which permit the holder to put their shares of the subsidiary back to the Group over a 10 -year period. The amount that may become payable under the option upon exercise is initially recognized at the present value
of the redemption amount within other accounts payable with a corresponding charge directly to equity. The charge to equity is recognized separately as written put options over non-controlling interests,
adjacent to non-controlling interest in the net assets of the consolidated subsidiaries.



F-25



---

(All amounts expressed in thousands of S/ unless otherwise stated)



Subsequently, the financial liability is updated for changes in the assumptions on which the
estimated expected cash outflows were based and a financial component for the passage of time. The effects of this update are recognized in the income statement as Other income/expense. In the event that the option expires unexercised, the liability
is derecognized with a corresponding adjustment to equity.



|2.24 | Capital
|---- | -------

Common shares are classified as equity.

Incremental costs directly attributable to the issue of new shares or options are shown in equity, as a deduction, net of taxes, of the
proceeds.

Where any Group company purchases the Companys equity shares (treasury shares), the consideration paid, including any
directly attributable incremental costs (net of income taxes) is deducted from equity attributable to the companys equity holders until the shares are cancelled or reissued. Where such shares are subsequently reissued, any consideration
received, net of any directly attributable incremental transaction costs and the related income tax effects is included in equity attributable to the Groups equity holders.



|2.25 | Revenue recognition
|---- | -------------------

Revenue is measured at the fair value of the consideration received
or receivable. The Group recognizes revenue when the amount of revenue can be reliably measured; when it is probable that future economic benefits will flow to the entity; and when specific criteria have been met for each of the Groups
activities.

The Groups revenue recognition policy is described as follows:



| | i) | Revenue from construction activities
| | -- | ------------------------------------

Revenues from construction contracts are recognized using
the percentage-of-completion method which is based on the completion of a physical proportion of the overall work contract considering total costs and revenues estimated
at the end of the project, in accordance with IAS 11, Construction Contracts. Under this method revenues are determined based on the proportion of actual physical completion compared to the total contracted physical construction commitment.

When it is probable that the total costs of the contract will be above the related revenue, the expected loss will be immediately expensed.

When the outcome of a construction contract cannot be estimated reliably, the associated revenue is recognized to the extent costs
incurred are recoverable. Revenue is billed once approval is received by the owners of the work in progress.

In the statement of financial
position, the Company shows the net position of each contract as an asset or a liability. A contract is considered an asset when the costs incurred plus recognized earnings less the sum of all the recognized losses and assessments exceed work in
progress billings; this asset is shown in the statement of financial position as Unbilled work in progress; otherwise they are presented as a liability within Trade accounts payables.

A change order is an instruction by the customer for a change in the scope of the work to be performed under the contract that may lead to an
increase or a decrease in contract revenue. A variation is included in contract revenue when it is probable that the customer will approve the variation and the amount of revenue arising from the variation; and the amount of revenue can be reliably
measured.



F-26



---

(All amounts expressed in thousands of S/ unless otherwise stated)



A claim is an amount that the Group seeks to collect from the customer or third party as
reimbursement for costs not included in the contract price. Claims are included in contract revenue only when negotiations have reached an advanced stage such that it is probable that the customer will accept the claim; and the amount that it is
probable will be accepted by the customer can be measured reliably.



| | ii) | Revenue from engineering, advisory, consulting services and other services
| | --- | --------------------------------------------------------------------------

Revenues from
service contracts are recognized in the accounting period in which they are performed using the percentage of completion method, calculated based on the percentage of costs incurred. Additionally, there are contracts whereby income is recognized as
it is earned, regardless of when the related fees are received.



| | iii) | Salesof real-estate properties
| | ---- | ------------------------------

Revenue from sales of real estate properties is
recognized in the results of the period when sales occur, that is, when the properties are delivered and the risks and rewards inherent to ownership are transferred to the buyer and the collection of the corresponding receivables is reasonably
assured.



| | iv) | Revenue from IT services
| | --- | ------------------------

The sale of computer equipment includes some services to be provided
in a subsequent date to the asset sale as installation and maintenance. When sales agreements include multiple elements, the amount of the revenue is attributed to each element based on their related fair values. The fair value of each element is
determined based on the market price prevailing for each element when sold separately. Revenue derived from computer equipment is recognized when the related risks and rewards are transferred to the customer, which occurs upon delivery. Revenue
relating to each service element is recognized using the straight line method.



| | v) | Interest income
| | -- | ---------------

Interest income is recognized on a time-proportion basis, using the effective
interest method.



| | vi) | Revenue for concession services
| | --- | -------------------------------

Revenue from concession services is recognized according to
its nature. Construction and restoration activities are accounted for applying the percentage-of-completion method as described above and operation and maintenance
services in the accounting period when they are provided (see Note 2.5).



|2.26 | Construction contract costs
|---- | ---------------------------

Contract costs include all direct costs such as materials,
labor, subcontracting costs, manufacturing and supply costs of equipment, start-up costs and indirect costs. Periodically, the Company evaluates the reasonableness of the estimates used in the determination of
the percentage-of-completion. If, as a result of this evaluation, there are modifications to the revenue or cost previously estimated, or if the total estimated cost of
the project exceeds expected revenues, an adjustment is made in order to reflect the effect in results of the period in which the adjustment or loss is incurred.

When the outcome of a construction work cannot be estimated reliably, the revenue of the contract is recognized only up to the amount of the
contractual costs incurred and that are likely to be recovered.

|2.27 | Leases

| | a) | The Group as a lessee
| | -- | ---------------------

Operating leases

Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases.
Payments made under operating leases, including prepayments (net of any incentives received from lessor) are charged to the consolidated income statement under the straight-line method over the lease term. The Groups major kinds of operating
leases are leases of machinery, computer equipment, printing equipment, among others.

Finance leases

Leases in which the Group assumes substantially all the risks and rewards of ownership of an asset are classified as finance leases. Each lease
payment is allocated between the liability and finance charges so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The corresponding rental obligations, net of finance charges, are
included in other payables, short- and long-term in the consolidated statement of financial position.

The interest element of the finance
cost is charged to the consolidated statement of comprehensive income over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The property, plant and equipment acquired
under finance leases is depreciated over the useful life of the asset or the lease term.



| | b) | Group as a lessor
| | -- | -----------------

The Group only has operating leases and the leased assets are stated in the
statement of financial position based on the nature of the asset. Revenue from operating leases are recognized under the straight-line method over the lease term and the incentives given to lessees reduce the revenue obtained from leases.



|2.28 | Dividend distribution
|---- | ---------------------

Dividend distribution to the Companys shareholders is
recognized as a liability in the financial statements in the period in which the dividends are approved by the Companys shareholders.



|2.29 | Significant non-operating items
|---- | -------------------------------

Significant non-operating items are separately shown in the financial statements when they are necessary to provide a more adequate understanding of the Groups financial performance. These material items are income or
expenses shown separately due to their nature or significant amount.



|2.30 | Restatement of Consolidated Financial Statements
|---- | ------------------------------------------------

Company Management identified the need
to make adjustments to the consolidated financial statements for the year 2015, so proceed to correct and restructure the financial statements as of December 31, 2015 in the items detailed below:

| | (1) | The Company performed a review of the estimates made of the work in progress, as well as impairments to the accounts receivable, determining the need to make adjustments to the account balances.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (2) | The Goodwill of Morelco S.A. during 2015 was recorded using the group the functional currency (soles). In the review conducted in 2016, it was identified that the registration should be made in the currency of the
subsidiary, generating a conversion adjustment.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (3) | Likewise, a review of deferred tax assets was conducted, determining the need to record adjustments in accordance with the adjustments described above.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------

As a result of the recording of these adjustments in the consolidated financial statements as of December 31, 2015, the Companys equity
decreased by approximately S / 86 million.



|3 | ADOPTION OF NEW INTERNATIONAL FINANCIAL INFORMATION REGULATIONS (IFRS), AMENDMENTS AND INTERPRETATIONS
|- | ------------------------------------------------------------------------------------------------------



|3.1. | Standards, amendments and interpretations adopted by the Group
|---- | --------------------------------------------------------------

The Company has adopted
as of January 1, 2016 the following amendments to the IFRSs and amendments to IFRSs considered for the first time in the preparation of the financial statements:



F-28



---

(All amounts expressed in thousands of S/ unless otherwise stated)



| |  |  | Annual improvements to IFRS, 2012-2014 cycles, which has required additional minor disclosures.
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | Acquisition of interest in an entity, amendment to IFRS 11 Joint Arrangements, this amendment clarifies that a joint operator that acquires an asset or group of assets in a joint operation that represents a
business in accordance with IFRS 3, applies the principles of IFRS 3 when accounting for the business combinations of the acquisition. This will result in a separate recognition of goodwill, if any arise in the acquisition. If the asset or group of
assets acquired does not constitute a business, the principles of IFRS 3 do not apply.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The amendment also clarifies that a joint operator that increases its interest in an existing joint operation in which the operator retains joint control does not again measure the interest previously held in the joint
operation
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Amendments to the disclosure initiatives, IAS 1 Presentation of the financial statements. The amendments intend to clarify a series of disclosure requirements that cover:
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The disclosure of significant accounting policies;
| | - |  | --------------------------------------------------



| |  |  | The application of materiality to the financial statements;
| | - |  | -----------------------------------------------------------



| |  |  | Presentation of subtotals;
| | - |  | --------------------------



| |  |  | Information to be presented in the other comprehensive income section of the performance statement; and
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | The structure of financial statements.
| | - |  | --------------------------------------

The adoption of these changes did not have a material
impact on the current year or prior years balances and they are not likely to affect future periods; however, the Group will give continuous consideration to the areas addressed in the amendments to help clear and concise information.



|3.2. | New standards, amendments and interpretations effective for financial statements of annual periods beginning on or after January 1, 2017 which have not been early adopted
|---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Amendments to IAS 7 Statement of cash flows requires the Group to include an additional disclosure that will enable users of financial statements to evaluate changes in liabilities arising from financing
activities.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Amendments to IAS 12 Income taxes clarifies i) the requirements for recognizing deferred tax assets on unrealized losses ii) the accounting for deferred tax where an asset is measured at fair value and that
fair value is below the assets tax base and iii) certain other aspects of accounting for deferred tax assets. These amendments are effective for annual financial periods beginning on or after January 1, 2017 and early application is
permitted. The Group does not expect these amendments may have a significant impact on its financial statements.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | IFRS 9, Financial instruments, addresses the classification, measurement and recognition of financial assets and financial liabilities. It replaces the guidance in IAS 39 on the classification and
measurement of financial instruments.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The standard is effective for accounting periods beginning on or after 1 January
2018. Early adoption is permitted. The Group does not expect that the changes in IFRS 9 may have a material impact on its criteria of classification and measurement of financial assets and liabilities.



| |  |  | IFRS 15, Revenue from contracts with customers, it replaces IAS 18 Revenue and IAS 11 Construction contracts and the related interpretations.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------

The new standard is based on the principle that income is recognized when the control of a good or service is transferred to a customer, in
such a way that the notion of control replaces the existing notion of risks and benefits. The new standard establishes a new five-step process that guides the revenue recognition, these are: (i) identify contracts with customers,
(ii) identify the performance obligation, (iii) determine the transaction price of the contract, (iv) allocate the transaction price to each of the performance obligations; and, (v) recognize the income as each performance
obligation is satisfied



F-29



---

(All amounts expressed in thousands of S/ unless otherwise stated)



The application of IFRS 15 may have flow-on
effects on the entitys business practices regarding systems, processes and controls, compensation and bonus plans, contracts, tax planning and investor communication.

The standard is effective for annual periods beginning on or after January 1, 2018 and early application is permitted.

The Group is in the process of estimating the effects of the application of IFRS 15; its assessment is being conducted by operating segment:
engineering and construction, infrastructure, real estate, technical services and parent company operation. At December 31, 2016, the Group has conducted qualitative assessment to identify impacts.

The Group estimates that the current procedure of revenue recognition defined according to its types of ordinary activities will not be
materially different from the current definition of the standard that is based on compliance with performance obligations, whether for a period or a point in time.

The Group is in the process of evaluating the methodology to be used for the transition of IFRS 15. At this point, despite the qualitative
evaluation, the Group cannot reasonably estimate the quantitative impacts that this standard would have on the financial statements.



| |  |  | IFRS 16 Leases, this standard replaces the current rules relating to the treatment of leases IAS 17 Leases and IFRIC 4 Contracts may contain a lease and other related interpretations.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

IFRS 16 is effective for financial periods beginning on or after January 1, 2019; early application if permitted
provided IFRS 15 is also early adopted. The Group is presently evaluating the impact of these standard on the preparation of its consolidated financial statements.



| |  |  | IFRIC 22, Foreign currency transactions and advance consideration, the new interpretation clarifies which date should be used for translation when a foreign currency transaction involves an advance
payment/receipt.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

This interpretation will impact all entities that enter into foreign currency transactions for which
consideration is paid or received in advance.

This interpretation is effective for financial periods beginning on or after January 1,
2018; early application is permitted. The Group is evaluating whether the changes introduced in IFRIC 22 may have a material impact on the qualifying criteria of date of transaction at their engineering and construction segment,
which is the one with significant advances balances.



| |  |  | IFRIC 23 Uncertainty over income tax treatments, it clarifies how the recognition and measurement requirements of IAS 12 Income taxes, are applied on the recognition and measurement of a tax
liability or asset in circumstances where there is uncertainty in the application of the tax law in concern.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Group is
required to consider whether it is probable that a taxation authority will accept an uncertain tax treatment. If an entity concludes that it is not probable that the treatment will be accepted, it should reflect the effect of the uncertainty in its
income tax accounting in the period in which that determination is made.

This IFRIC is effective for financial periods beginning on or
after January 1, 2019 and early application is permitted. The Group is evaluating the impact of this standard on its financial statements.

|4 | FINANCIAL RISK MANAGEMENT
|- | -------------------------

Financial risk management is carried out by the Groups
Management. Management oversees the general management of risks in specific areas, such as foreign exchange rate risk, price risk, cash flow and fair value interest rate risk, credit risk, the use of derivative and
non-derivative financial instruments and the investment of excess liquidity as well as financial risks, and carries out periodic supervision and monitoring.



|4.1 | Financial risk factors
|--- | ----------------------

The Groups activities expose it to a variety of financial
risks: market risk (including foreign exchange risk, price risk, fair value interest rate risk and cash flow interest rate risk), credit risk and liquidity risk.

The Groups overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse
effects on the Groups financial performance. The Group uses derivative financial instruments to hedge certain risk exposures in one of its subsidiaries and considers the use of other derivatives in the event that it identifies risks that may
generate an adverse effect for the Group in the short and medium-term.



| | a) | Market risks
| | -- | ------------



| | i) | Foreign exchange risk
| | -- | ---------------------

The Group is exposed to exchange rate risk as a result of the
transactions carried out locally in foreign currency and due to its operations abroad. As of December 31, 2016 and 2015, this exposure is mainly concentrated in fluctuations of U.S. dollar, the Chilean and Colombian Pesos. The foreign exchange
risk of the investments in Bolivia and Panama are not significant due to the volume of operations.

At December 31, 2016, the
consolidated statement of financial position includes assets and liabilities in foreign currency (mainly in U.S. dollars) equivalent to S/2,770.9 million and S/2,708.3 million, respectively (S/1,659 million and S/2,404 million,
respectively, at December 31, 2015) equivalents to US$826.6 million and US$806 million, respectively (US$486.7 million and US$704.5 million, respectively at December 31, 2015).

During 2016, the Peruvian Sol, the Chilean and Colombian Pesos were exposed against the U.S. dollar. The Groups exchange gains and losses
for 2016 amounted to S/761.8 million and S/774.3 million, respectively (S/427.2 million and S/510.1 million, respectively, in 2015 and S/357.3 million and S/401.6 million, respectively in 2014).

If at December 31, 2016 the Peruvian Sol and the Chilean and Colombian Pesos had strengthened/weakened by 2% against the U.S. dollar, with
all other variables held constant, the pre-tax profit for the year would have increased/decreased by S/0.3 million (S/1.7 million in 2015 and S/0.9 million in 2014).

At December 31, 2016 the consolidated statement of changes in equity comprises a foreign currency translation adjustment originated by its
subsidiaries. Their financial position includes assets and liabilities in functional currency equivalent to CLP$75,561.3 million and CLP$87,221.1 million, respectively (CLP$85,238 million and CLP$80,378 million, respectively at
December 2015), COP$169,774.8 million and COP$166,091.8 million, respectively (COP$265,370 million and COP$309,446, respectively at December 2015).

The Groups foreign exchange translation adjustment for 2016 amounted to S/0.6 million (expenses for S/44.6 million in 2015 and
S/20.5 million in 2014).

| | ii) | Price risk
| | --- | ----------

Management considers that the exposure of the Group to the price risk of its
investments in mutual funds, bonds and equity securities is low, since the invested amounts are not significant. Any fluctuation in their fair value will not have any significant impact on the balances reported in the consolidated financial
statements.



| | iii) | Cash flow and fair value interest rate risk
| | ---- | -------------------------------------------

The Groups interest rate risk mainly arises
from its long-term borrowings. Borrowings issued at variable rates expose the Group to cash flow interest rate risk. Borrowings issued at fixed rates expose the Group to fair value interest rate risk. Group policy is to maintain most of its
borrowings at fixed rate instruments; 52.8% of total debt in 2016 (72.7% in 2015) was contracted at fixed rates and 47.2% at variable rates (27.3% in 2015) which consisted of a 18.0% fixed rate plus VAC (adjusted for inflation) and the remaining
29.2% at a variable rate (23.6% fixed rate + VAC and the remaining 3.7% at a variable rate in 2015).

The debt subject to fixed rate plus
VAC is related to a bond issued in Peruvian soles to finance the GyM Ferrovías Project, Metro Line 1 (Note 20). Any increase in the interest rate resulting from higher inflation will have no significant impact on the Groups profit
because these revenues are also adjusted for inflation.

During 2016 and 2015 borrowings at variable rates are denominated in Peruvian
Soles and U.S. dollars and the Groups policy is to manage their cash flow risk by using interest-rate swaps, which are recognized under hedge accounting. However, regarding the variable rate loans related to GSP (Note 19-a), Management decided to assume the risk since it expects to pre-pay them before due. If at December 31, 2016, the libor rate plus 3 months had increased/ decreased
by 5%, with all other variables held constant, the pre-tax profit for the year would have increased/ decreased by S/1.4 million (there was not a material effect on the Groups results in 2015). There
was no material ineffectiveness on cash flow hedges occurred in fiscal years 2016 and 2015.



| | b) | Credit risk
| | -- | -----------

Credit risk arises from cash and cash equivalents and deposits with banks and
financial institutions, as well as customer credit counterparties, including the outstanding balance of accounts receivable and committed transactions. For banks and financial institutions, only independently rated parties with a minimum rating of
A are accepted.

With respect to loans to related parties, the Group has measures in place to ensure the recovery of these
loans through the controls maintained by the Corporate Finance Management and the performance evaluation conducted by the Board.

No credit
limits were exceeded during the reporting period, and Management does not expect the Group to incur any losses from performance by these counterparties, except for the ones already recorded at the financial statements.



| | c) | Liquidity risk
| | -- | --------------

Prudent liquidity risk management implies maintaining sufficient cash and cash
equivalents, the availability of funding through an adequate number of sources of committed credit facilities and the capacity to close out positions in the market. Historically, the Group cash flows enabled it to maintain sufficient cash to meet
its obligations. However, as of December 31, 2016, the Group started to experienced liquidity risk due to the early termination of the GSP concession agreement and the obligations assumed (Note 16 a-i).
As a consequence, the Group has started a disinvestment plan to be able to meet the obligations resulting from this scenario (Note 37).

Group Corporate Finance monitors rolling forecasts of the Groups liquidity requirements
to ensure it has sufficient cash to meet operational needs while maintaining sufficient headroom on its undrawn borrowing facilities (Note 19), so that the Group does not breach borrowing limits or covenants, where applicable, on any of its
borrowing facilities. Less significant financing transactions are controlled by the Finance Management of each subsidiary.

Such
forecasting takes into consideration the Groups debt financing plans, covenant compliance, compliance with internal statement of financial position ratio targets and, if applicable, external regulatory or legal requirements; for example,
foreign currency restrictions.

Surplus cash held by the operating entities over the balance required for working capital management are
invested in interest-bearing checking accounts or time deposits, selecting instruments with appropriate maturities and sufficient liquidity.

The table below analyzes the Groups financial liabilities into relevant maturity groupings based on the remaining period from the date of
the statement of financial position to the contractual maturity date. The amounts disclosed in the table are the contractual undiscounted cash flows.

|4.2 | Capital management
|--- | ------------------

The Groups objectives when managing capital are to safeguard
the Groups ability to continue as a going concern in order to provide returns for shareholders, benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital. As described at Note 1, in 2016 the
current situation of the Company, has lead Management to monitor deviations that might cause the non-compliance of covenants and may hinder renegotiation of liabilities
(Note19-a and Note 37-c).

In order to maintain or adjust
the capital structure, the Group may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets to reduce debt.

The Group monitors capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is
calculated as total borrowings (including current and non-current borrowings), less cash and cash equivalents. Total capital is calculated as equity as shown in the consolidated statement of
financial position plus net debt.

|4.3 | Fair value estimation
|--- | ---------------------

For the classification of the type of valuation used by the Group
for its financial instruments at fair value, the following levels of measurement have been established.



|  |  |          |  |                                                                                                                                                                                                                
|- |  | -------- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |  | Level 1: |  | Measurement based on quoted prices in active markets for identical assets or liabilities.                                                                                                                      
|  |  |         
| |  | Level 2: |  | Measurement based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices).
|  |  |         
| |  | Level 3: |  | Measurement based on inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs, generally based on internal estimates and assumptions of the Group).        

The table below shows the Groups assets and liabilities measured at fair value at December 31, 2015
and 2016:

The carrying amounts of cash and cash equivalents correspond to their fair values. The Company considers that
the carrying amount of trade accounts receivable and payable is similar to their fair values since they are short term. The fair value for long-term receivables and liabilities is disclosed in Note 11, Note 12, Note
19-c, Note 20 and Note 22. The fair value of financial liabilities has been estimated by discounting the future contractual cash flows at the interest rate currently prevailing in the market and which is
available to the Company for similar financial instruments (Level 2).



|5 | CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS
|- | -------------------------------------------

Estimates and judgments used are
continuously evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.



|5.1 | Critical accounting estimates and assumptions
|--- | ---------------------------------------------

The Company makes estimates and
assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts
of assets and liabilities within the next financial year are addressed below.



| | a) | Estimated impairment of goodwill and other intangible assets with indefinite useful life
| | -- | ----------------------------------------------------------------------------------------

Impairment reviews are undertaken annually to determine if goodwill arising from business acquisitions and other intangible assets with
indefinite useful life are impaired, in accordance with the policy described in Note 2.15-i). For this purpose, goodwill is allocated to the different CGUs to which it relates while other intangible assets
with indefinite useful life are assessed individually. The recoverable amounts of the CGUs and of other intangible assets with indefinite useful life have been determined based on the higher of their value-in-use and fair value less costs to sell. This evaluation requires the exercise of Managements professional judgment to analyze any potential indicators of impairment as well as the use of
estimates in determining the value in use, including preparing future cash flows, macro-economic forecasts as well as defining the interest rate at which said cash flows will be discounted.

If the Group experiences a significant drop in revenues or a drastic increase in costs or changes in other factors, the fair value of their
business units might decrease. If management determines the factors that reduce the fair value of the business are permanent, those economic factors will be taken into consideration to determine the recoverable amount of those business units and
therefore, goodwill as well as other intangible assets with indefinite useful life may be deemed to be impaired, which may cause their write-down to be required.

(All amounts expressed in thousands of S/ unless otherwise stated)



Based on the impairment tests performed by Group Management, no goodwill nor intangible
(trademarks) impairment losses were required to be recognized because the recoverable amount of the CGUs subject to testing was substantially higher than their related carrying amounts.

The most significant assumptions used in impairment testing are gross margin, discount rate, terminal growth rate and revenue growth rate which
are included in Note 18.

At December 31, 2015 and 2016 the Group has performed a sensitivity analysis increasing or decreasing the
assumptions of gross margin, discount rate and revenue and terminal growth rate by a 10%, with all the other variables held constant, as follows:

In 2016 if the revenue growth rate or terminal growth rate had been 10% below
Managements estimates, or the discount rate had been 10% above Managements estimates, the Group would have recognized a provision for impairment of their trademark Adexus.

At December 31, 2016, as a result of these evaluations, an impairment was identified and recorded in one of the CGU, Vial and Vives DSD
(Note 18).



| | b) | Income taxes
| | -- | ------------

Determination of the tax obligations and expenses requires interpretations of the
applicable tax laws and regulations. The Company seeks legal and tax counsel before making any decision on tax matters. Although Management considers its estimates to be prudent and appropriate, differences of interpretation may arise with Tax
Authorities (mainly Peruvian, Chilean and Colombian Authorities) which may require future tax adjustments.

Deferred tax assets and
liabilities are calculated on the temporary differences arising between the tax basis of assets and liabilities and the amounts stated in the financial statement using the tax rates in effect in each of the years in which the difference is expected
to reverse. Any change in tax rates will affect the deferred income tax assets and liabilities. This change will be recognized in the income statement in the period in which the change takes effect.

Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the
temporary differences and tax loss carryforwards can be utilized. For this purpose, the Group takes into consideration all available evidence, including factors such as historical data, projected income, current operations and tax planning
strategies. A tax benefit related to a tax position is only recognized if it is more likely than not that the benefit will ultimately be realized.

The Groups maximum exposure to tax contingencies amounts to S/11.3 million.



| | c) | Percentage of completion revenue recognition
| | -- | --------------------------------------------

Revenues from construction contracts are
recognized using the percentage-of-completion method which is based on the completion of a physical proportion of the overall work contract considering total costs and
revenues estimated at the end of the project (Note 2.25 i).

As of December 31, 2016, 2015 and 2014, a sensitivity analysis was
performed considering a 10% increase/decrease in the Groups gross margins, as follows:

| | d) | Provision for well closure costs
| | -- | --------------------------------

At December 31, 2016 the present value of the estimated
provision for closure of 144 wells located in Talara amounted to S/17.2 million (S/7.3 million as of December 31, 2015 for closure of 78 wells). The well closure liability is adjusted to reflect the changes that resulted from the
passage of time and from reviews of either the date of occurrence or the amount of the present value of the originally estimated obligations (Note 18).

The Group estimates the present value of its future obligation for well closure costs, or well closure liability, and increases the carrying
amount of the asset that will be withdrawn in the future and that is shown under the heading of intangibles in the statement of financial position.

The pre-tax discount rate used for the present value calculation was 1.93% for Blocks I and V, and
2.93% for Blocks III and IV, respectively, based on a 5 to 30-year rate used on U.S. bonds effective at December 31, 2016 (2.09% based on the 7-year bond rate at
December 2015 for Blocks I and V).

If, at December 31, 2016 and 2015, the estimated rate had increased or decreased by 10%, with all
variables held constant, the impact on pre-tax profit would have not been significant.



| | e) | Impairment of investment in Gasoducto Sur Peruano
| | -- | -------------------------------------------------

Based on the termination of the concession
agreement, on which Gasoducto Sur Peruano S.A. (GSP) acts as concessionaire (Note 16.a-i and Note 37), the Group identified potential impairment indicators affecting the recoverability of its investment.
Consequently, the Group has applied the rules stated in IAS 36, Impairment of assets to determine the recoverable amount of this investment.

In that process, the Group has applied judgement to weight the various uncertainties surround the amount that can be recovered from this
investment. Management has determined the recoverable amount assuming two key factors: (i) the amount that GSP will recover as a result of the public auction, and (ii) the validity of its right to subordinate the Odebrecht Groups
debts in GSP.

With relation to the amount to be recovered by GSP; the Group is assuming a recovery of the minimum amount established in
the concession agreement, which is equivalent to 72.25% of the Net Carrying Amount (NCA) of the Concession assets. This amount, in substance, represents a minimum secured payment to be obtained by GSP based on a public auction (liquidation) to be
set up for the adequate transfer of the Concessions assets to a new Concessionaire within a year, under the relevant contractual terms and conditions.

With relation to the validity of its right to subordinate the Odebrecht Groups liabilities in GSP, Management assessment, in consultation
with its legal advisors, is that, although some uncertainties exist, these do not represent a material risk for exercising this right.

The
concession agreement also established two additional tranches of 82.5% or 100% of the NCA to be recovered as a result of public auction, depending on several factors. In any of these scenarios, the Group would be able to recover their total
investment and no additional impairment would be necessary to be recognized.

Depending on the date in which the NCA is actually cashed,
the Group may need to take into account additional costs ranging from S/18.95 million (US$5.64 million) to S/42.2 million (US$12.56 million), due to higher financial expense.

| | f) | Impairment of the investment in Consorcio Constructor Ductos del Sur (CCDS)
| | -- | ---------------------------------------------------------------------------

CCDS was mainly
engaged in performing the engineering, procurement and construction work for GSP. Due to the early termination of GSP, the Group applied the rules stated in IAS 36 Impairment of assets and IAS 37 Provisions to determine the
recoverable amounts of the assets and liabilities to be recorded, respectively. As a result, the following adjustments were included at the financial statements:

|                                          |  |    |          |  



| | (i) | The extinguished trade accounts payable relates to the recognition of the construction project estimated margin recorded as a liability (Note 2.25.i)
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------

| | (ii) | The recoverable of unbilled work in progress relates to the minimum secured payment to be obtained from GSP.
| | ---- | ------------------------------------------------------------------------------------------------------------

| | (iii) | Inventories were specialized assets that could not be sold in an active market.

In 2016, the
net impact of the early termination of CCDS construction contract is a loss of S/15.2 million.



|5.2 | Critical judgments in applying the entitys accounting policies
|--- | ---------------------------------------------------------------

Consolidation
of entities in which the Group holds less than 50%

The Company owns some direct and indirect subsidiaries of which the Group has
control even though it has less than 50% of the voting rights. These subsidiaries mainly comprise indirect subsidiaries in the real-estate business owned through Viva GyM S.A., where even though the Group holds interest between 30% and 50%, has the
power to affect the relevant activities that impact the subsidiaries returns. Additionally, the Group has de facto control over Promotora Larcomar S.A. of which it owns 46.55% of equity interest.

Consolidation of entities in which the Group does not have join control but have rights and obligations over the assets and liabilities

The Group assesses, on an ongoing basis, the nature of the contracts signed with one or more parties. If no control or joint control
is determined to be held by the Group but it has rights to assets and obligations for liabilities under the arrangement, then the Group recognizes its assets, liabilities, revenue and expenses and its share of any jointly controlled assets or
liabilities and any revenue or expense arising under the arrangement as a joint operation in accordance with IFRS 11Joint arrangements (Note 2.2-d).

| | b) | Public services concessions
| | -- | ---------------------------

The Group acts as an operator in various public service
concessions. When applicable, revenue attributable to the construction or restoration of infrastructure has been accounted for by applying the models set forth in Note 2.5 (financial asset, intangible asset and bifurcated models).

Subsidiary Transportadora de Gas Natural Comprimido Andino S.A.C. (hereinafter TGNCA) held a concession to design, finance, construct, maintain
and operate the compressed natural gas supply system to be implemented in certain cities. The Concession was recognized under the financial asset model. In September 2016 the Concession Agreement was terminated on the grounds of counterpartys
failure to meet the required conditions (availability of assets and resources). As a result, TGNCA recognized an impairment loss of receivables amounting to S/6.3 million, which is included in the income statement within cost of services
provided (Note 27). The balance remaining relates to trade accounts receivable for S/38.7 million, to be received from the Ministry of Energy and Mines. This balance was classified as current assets because Management expects a favorable
outcome of the award.

In all the Group concessions, the infrastructure is returned to grantor at the end of the concession
agreement. The concessions held by the Group are as follows at December 31, 2016:

|7 | SEGMENT REPORTING
|- | -----------------

Operating segments are reported consistently with the internal
reports that are reviewed by the Group chief decision-maker; that is, the Executive Committee, which is led by the Corporate General Manager. This Committee is the chief operating decision maker, responsible for allocating resources and
evaluating the performance of each operating segment.

The Groups operating segments are assessed by the activities of the following
business units: (i) engineering and construction, (ii) infrastructure, (iii) real estate and (iv) technical services.

(All amounts expressed in thousands of S/ unless otherwise stated)



As set forth under IFRS 8, reportable segments based on the level of revenue are:
engineering and construction and technical services. However, the Group has voluntarily decided to report on all its operating segments as detailed in this Note.

The revenues derived from foreign operations (Chile, Panama, Dominican Republic, Colombia, Bolivia, Ecuador and Guyana) comprise 25.4% of the
Groups total revenue reported in 2016 (27.1% in 2015 and 19.9% in 2014).

Sales between segments are carried out at arms
length, are no material, and are eliminated on consolidation. The revenue from external parties is measured in a manner consistent with that in the income statement. Sale of goods relate to the real state segment. Revenue from services relate to all
other segments.

Group sales and receivables are not concentrated in a few customers. There is no external customer that represents 10% or
more of the Groups revenue.

The following segments set forth the principal activities of the Group:



| | a) | Engineering and construction: This segment includes from traditional engineering services such as structural, civil and design engineering, and architectural planning to advanced specialties including process design,
simulation, and environmental services at four divisions; i) civil works, such as the construction of hydroelectric power stations and other large infrastructure facilities; (ii) electro mechanic construction, such as concentrator plants, oil
and natural gas pipelines, and transmission lines; iii) building construction, such as office buildings, residential buildings, hotels, affordable housing projects, shopping centers and industrial facilities; and iv) services related to mining, such
as earthworks, blasting, loading and hauling ore.

| | b) | Infrastructure: The Group has long-term concessions or similar contractual arrangements in Peru for three toll roads, the Lima Metro, a waste water treatment plant in Lima, four producing oil fields, and a gas
processing plant.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | c) | Real Estate: The Group develops and sells homes targeted to low and middle-income population sectors which are experiencing a significant increase in disposable income, as well as, office and commercial space to a
lesser extent.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | d) | Technical Services: The Group provides: (i) operation and maintenance services for infrastructure assets; (ii) information technology (IT) services, including IT outsourcing, systems integration, application
and business process outsourcing services; and (iii) electricity networks services (maintenance) in telecommunications.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | e) | Parent Company Operation corresponds to the services which the Holding company provides, management, logistics and accounting services, among others.

|10 | OTHER FINANCIAL ASSETS
|-- | ----------------------

On April 2016, the Company sold their 1.64% of interest held in
Transportadora de Gas del Perú S.A. (TGP) for S/107.3 million, resulting in a net profit of S/46.3 million, as shown in the income statement, within Profit (loss) on sale of investments. The balance of its investment at
the date of sale was S/117.1 million.

The cumulative amount of fair values at the date of sale amounting to S/41.5 million
(S/56 million of gain on fair value and S/14.6 million of income tax), as recognized in the statement of other comprehensive income was transferred to profits for the period.

At December 31, 2015 the fair value of the Groups interest in TGP equals S/120.1 million based on the discounted cash flow
method. The information used in the calculation was as follows:



| |  |  | Discounted cash flows from operating activities of TGP net of cash flows from investment activities (CAPEX).
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | Cash flows were estimated for a 30-year term.
| | - |  | ---------------------------------------------



| |  |  | The discount rate used was 7.5% corresponding to estimated TGPs WACC.
| | - |  | ----------------------------------------------------------------------



| |  |  | The interest of the Company in TGP was 1.64%.
| | - |  | ---------------------------------------------

The fluctuation in the fair value of this
investment in 2015 amounted to S/19.9 million (S/4.6 million in 2014) net of its income tax effect amounting to S/7 million (S/1.3 million in 2014), which was recognized in the statement of other comprehensive income.

In 2015 dividends from this investment were received for a total S/7.2 million (S/9.3 million in 2014) included within Other income
(Note 29).

The most significant assumptions are the discount rate and cash flows affected by the U.S. Wholesale Price Index; the Group
performed a sensitivity analysis of this assumptions: if the discount rate were adjusted down by 5% the fair value would be 7.4% lower; and if the discount rate were adjusted up by 5% the fair value would be 7.1% higher; if the cash flows were
adjusted down by 5% the fair value would be 9.1% lower and if the cash flows were adjusted up by 5% the fair value would be 8.8% higher.

In addition to the GSP acquisition described in Note 16 a-i); in 2014,
2015 and 2016 the following significant movements were noted:



| |  |  | During 2016 cash contributions were made principally to Gasoducto Sur Peruano S.A. and Concesionaria Chavimochic amounting to S/373.9 million and S/15.7 million, respectively.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In 2016 the Group obtained dividends mainly from Betchel Vial y Promoción Inmobiliaria del Sur S.A. amounting to S/6.3 million and S/3.8 million, respectively. In 2015 the Group received dividends from
Promoción Inmobiliaria del Sur S.A. amounting to S/9.8 million (from Promoción Inmobiliaria del Sur S.A., Ingeniería y Construcción Vial y Vives OGP -1 Limitada y Betchel Vial
y Vives Servicios Complementarios Ltda. for S/3.4 million, S/16.6 million and S/4.9 million, respectively in 2014).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In 2016, the Group included an impairment provision of GSP for S/593.1 million (US$176.49 million). See subsequent events after the date of the statement of financial position in Note 37.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In 2015, the share of the profit or loss in associates and joint ventures under the equity method shown in the income statement includes S/17.3 million as expenses that subsidiary GyM S.A. had to pay
for the execution of the letter of guarantee in JV Panama.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In March 2014, Constructora Norberto Odebrecht S.A. and Odebrecht Partipacoes e Investimentos S.A. formed Concesionaria Chavimochic S.A.C., in which the Company had a 26.5% interest based on a capital contribution of
S/13.3 million.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In December 2014, subsidiary Viva GyM S.A. made a capital contribution of S/37.8 million, by which it joined the Panama Project initially carried out by a third party and the Group and by which a 35% interest was
obtained. On December 17, 2015 the business operating structure was decided to be changed, which resulted in the extinguishment of the association and the formation of a consortium by which the partners would have joint control of the business,
with no effect on their percentage share in profit distribution. From that date onwards, the Group ceased to use the equity method of accounting to recognize the investment and began to use the joint operation accounting treatment.

Management reviews the results of its businesses based on the type of economic
activity carried out.

At December 31 goodwill allocated to cash-generating units (CGU) are:

As a result of the impairment testing on goodwill performed by Management on an annual basis, the recoverable
amount of the related cash-generating unit is determined based on the higher of its value in use and fair value less cost of disposal. Value in use is determined based on the future cash flows expected to be generated by the assessed CGU.

As a result of these assessments an impairment was identified in one of the CGUs, Vial y VivesDSD, and was accounted as of December
31st, 2016. The loss to impairment was generated due to the decrease in the expected flows, as a result of the reduction of the contracts linked to the Backlog. The amount of the impairment it impacted the total amount of goodwill was
S/38.7 million.

Major assumptions used by the Group in determining the fair value less cost of disposal and the value in use were as
follows:

These assumptions have been used for the analysis of each CGU included in the operating economic activities
for a period of 5 years.

Management determines the budgeted gross margins based on past results and market development expectations.
Average growth rates are consistent with those prevailing in the industry. Discount rates used are pre-tax or post-tax as appropriate and reflect the specific risk
related to the assessed CGUs.



| | b) | Trademarks -
| | -- | ------------

This item mainly comprises the trademarks acquired in the business combination
processes with Vial y Vives S.A.C. (S/75.4 million) in October 2012; Morelco S.A.S. (S/33.33 million) in December 2014; and Adexus S.A. (S/9.1 million) in August 2016. Management determined that the brands obtained from Vial y Vives, Morelco and
Adexus have indefinite lives; consequently, annual impairment tests are performed on these intangibles, as described in paragraph a) above.

| | c) | Concessions -
| | -- | -------------

The Concessions intangibles at December 31, 2016 mainly consist of:
i) EPC contract for S/405 million (S/317.5 million at December 31, 2015) comprising the construction of the second section of Ancón-Huacho-Pativilca highway; ii) improvement
of highway for S/18.1 million (S/19.6 million at December 31, 2015), and iii) Borrowing costs that were capitalized for a total of S/22.5 at an interest rate ranging from 7.14% y 8.72% (S/7.7 million in 2015 at an interest rates
ranging from 6.75% to 8.375%). By those contracts, the Concessionaire should perform activities to construct, improve and remediate road infrastructure during the Concession effective period.



| | d) | Costs of development of wells -
| | -- | -------------------------------

Through one of its subsidiaries, the Group operates and
extracts oil from two oil fields (Block I and Block V) located in the province of Talara in northern Peru. Both oil fields are operated under long-term service agreements by which the Group provides hydrocarbon extraction services to Perupetro.

On December 10, 2014 the Peruvian Government granted subsidiary GMP S.A. a right of exploiting for 30 years the oil blocks III and IV
(owned by the Peruvian government-run entity- Perupetro) located in Talara, Piura, 230 wells and 330 wells respectively. The total investment expected to be made in both wells is estimated to be
US$560 million; operations began in April 2015 in both blocks.

As part of the Groups obligations under the relevant service
agreements, certain costs will be incurred in preparing the wells in Blocks I, III, IV and V. These costs are capitalized as part of intangible assets at a carrying amount of S/80 million at December 31, 2016 (S/118.4 million at
December 31, 2015).

All blocks are amortized on the basis of the useful lives of the wells (estimated to be 5 years for Blocks I and
V and 10 years for Blocks III and IV), which is less than the total effective period of the service agreement with Perupetro.

In December 2015, the Group entered into a medium term loan
credit agreement for up to US$200 million (equivalent to S/672 million), with Credit Suisse AG, Cayman Islands Branch, Credit Suisse AG, Cayman Islands Branch and Credit Suisse Securities (USA) LLC. The initial term of the loan was set at five
years, with quarterly installments starting to be paid on the 18th month. The loan accrued interest at a rate of three months Libor plus 3.9% per year. The proceeds were used to finance the equity interest in GSP. As of December 31, 2016, the
outstanding balance amounted to US$148.5 million (equivalent to S/498.8 million), and it is included within the current portion.

On
June 27, 2017, the Group renegotiated the terms of this loan to clear breaches related to the termination of the GSP concession. The new terms require repayment by December, 2020, with required prepayments to be made with the proceeds of asset
sales of 40% in the first year and an additional 30% in the second year of the amendment. The syndicated loan accrues interest at LIBOR plus 4.90% per year. Under the amendment, the Group is prohibited from paying dividends until the loan is fully
repaid. The loan is secured by (i) a lien on Concars shares; (ii) a lien on Almontes shares; (iii) a mortgage over certain real estate properties in Miraflores and Surquillo; (iv) liens on certain accounts; (v) a
lien on GyMs share; (vi) a second lien on CAM Holding SPAs shares; (vii) a second lien on CAM Servicios del Perú S.A.s shares; and (viii) a first lien on cash flows from the sale of certain assets.

The agreement contains certain covenants, including the obligation by the Company to maintain the following financial ratios during the term of
the agreement: (1) the Consolidated EBITDA to Consolidated Interest Expense Ratio shall not be less than 3.5:1.0 commencing on April 1, 2018 and thereafter; (2) the Consolidated Leverage Ratio (as defined therein) shall not be greater
than 3.5:1.0 at any time during the period commencing on December 31, 2016 and ending on March 31, 2017; 3.5:1.0 at any time during the period commencing on July 1, 2017 and ending on September 30, 2017; and no greater than

April 1, 2018 and thereafter.

(All amounts expressed in thousands of S/ unless otherwise stated)



As of the date of this annual report, we are under continuing default in this financing due
to the non-delivery of the audited consolidated financial statements of Graña y Montero and GyM for the 2016 and 2017 fiscal years. The syndicated loan required that we provide the financial statements for the 2016 and 2017 fiscal years no
later than April 30, 2018. We are in the process of obtaining waivers from the lenders.

As of to date, the outstanding balance of the loan
capital is US$81.1 million (equivalent to S/264.9 million).



| | ii) | GSP Bridge Loan -
| | --- | -----------------

At December 31, 2016, the current balance includes US$129 million
(equivalent to S/433.3 million) of the corporate guarantee issued by the Company to secure the bridge loan given to GSP, which was enforceable at that date. On June, 2017, the Company has reached a new term loan with Natixis, BBVA, SMBC and MUFJ for
US$78.7 million (equivalent to S/264.8 million), the proceeds of which were used to repay the GSP bridge loan.

The maturity is June,
2020, with required prepayments to be made with the proceeds of asset sales of 40% in the first year and an additional 30% in the second year. The new term contains the following covenant: the consolidated leverage ratio shall not be more than
3.5:1.0 at any time, and accrues interest at LIBOR plus 4.50% per year, which increases to 5.00% during the second year and 5.50% during the third year. Under the new term, the Group is prohibited from paying dividends until the loan is fully
repaid. Also, the new term is secured by (i) a first lien on rights to receive the termination payment derived from the GSP termination (the VCN), (ii) a second lien on our shares of GyM and Concar; (iii) a second lien on our
shares of Almonte; (iv) a second lien on certain real estate properties in Miraflores and Surquillo; (v) a second lien on our shares of CAM Holding SPA; (vi) a second lien on our shares of CAM Servicios del Perú S.A.; and
(vii) a first lien on cash flows from the sale of certain assets.

As of the date of this annual report, we are under certain
continuing defaults under the term loan with respect to certain financial ratios and the non-delivery of the audited consolidated financial statements of Graña y Montero for the 2016 and 2017 fiscal years. The term loan required that we
provide the financial statements for the 2016 and 2017 fiscal years no later than April 30, 2018. As of March 2018, (a) our Consolidated Leverage Ratio (as defined therein) was 2.62, rather than no more than 2.50 as required under the syndicated
loan and (b) [●]. We are in the process of obtaining waivers from the lenders.

Advances received from customers relate mainly to construction projects and are discounted from billing under
the terms of the relevant agreements.

The fair value of the short-term payables approximates their carrying amount due to their short-term
maturities. The non-current portion, mainly comprises non-financial liabilities such as advances received from customers; the remaining balance is not significant for
any period shown in the financial statements.

(All amounts expressed in thousands of S/ unless otherwise stated)



At December 31, 2016, legal claims mainly comprise provisions for labor liabilities and
tax claims for S/14.7 million (S/8 million at December 31, 2015). Claims with the tax authority have been accounted for based on management estimates of the amounts the Group would most likely be required to pay in regard of these
current court actions. Due to the fact those amounts will depend on the tax authority, the Group does not have an estimated timing of when these cash outflows would be required.

This legal claims balance also includes court actions brought against the Group by the Peruvian energy regulator (OSINERGMIN) resulting from
the storage of hydrocarbons and the applicable environmental laws and regulations for S/6.3 million (S/6.1 million at December 31, 2015).

The gross movement of other provisions is broken down as follows:

At December 31, 2016, total tax losses amounted to S/507.3 million of which S/22.28 million are
expected to be applied in 2017, S/57.55 million in 2018 and the remaining balance in the following fiscal years (S/334.5 million in 2015, of which S/53.6 were expected to be applied in 2016, S/56.9 million in 2017 and the remaining
balance in the following fiscal years).

Tax goodwill arose from a tax credit balance resulting from the reorganization of Chilean
subsidiaries in 2014 under Chilean tax laws and regulations. In 2016, the arbitration process relating to Project Collahuasi was completed and an additional payment was determined to be paid to the Chilean subsidiary selling party; which resulted in
a higher balance in this item.

|30 | TAX SITUATION
|-- | -------------



| | a) | In accordance with current legislation in Peru, Chile, Brazil, Colombia, Ecuador, Bolivia, Guyana and Panama, each company in the Group is individually subject to the applicable taxes. Management considers that it has
determined the taxable income under general income tax laws in accordance with the tax legislation current effective of each country.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b) | Changes in the Peruvian Income Tax Law -
| | -- | ----------------------------------------

By means of Law No.30296 enacted on December 31,
2014 amendments to Income Tax Law have been made, which are effective starting in fiscal year 2015 onwards. Among these amendments, it should be noted the progressive reduction in the corporate income tax rate (on the Peruvian third-category income
earners) from 30% to 28% for fiscal years 2015 and 2016; then a reduction to 27% for fiscal years 2017 and 2018; and a final reduction to 26% from fiscal year 2019 onwards. Tax on dividends and other forms of profit distribution, agreed on by any
legal entities to individuals and non-domiciled legal persons is to be progressively increased from 4.1% to 6.8% for distributions that are agreed on or paid during fiscal years 2015 and 2016; then an increase
to 8.8% for fiscal years 2017 and 2018 will be effective; and a final increase to 9.3% will be effective from fiscal year 2019 onwards. The distribution of retained earnings until December 31, 2015 will continue to be subject to a 4.1% tax even
when the distribution is to be made in the subsequent years.

By means of Legislative Decree No. 1261, enacted on December 10,
2016 the Peruvian income tax law was amended to be effective from fiscal 2017 onwards. This amendment sets forth a corporate income tax rate of 29.5%. It also sets forth an income tax rate on dividends of 5% applicable to non-domiciled legal entities and individuals effective from fiscal 2017 onwards. Undistributed profits up to December 31, 2016 will continue to be affected to a 6.8% income tax rate regardless of whether the
distribution is agreed or occurs in subsequent periods.



| | c) | Amendments to Income Tax Law in Chile -
| | -- | ---------------------------------------

On September 29, 2014, Law No 20780 was enacted
by which certain changes are made to the Chilean tax system, such as: changes in the Income Tax Law, VAT Law and Tax Code. Also, on February 1, 2016 Law No 20899 was enacted to simplify and define the application of the above-mentioned tax
reform. With respect to income tax, two systems have been established:



F-94



---

(All amounts expressed in thousands of S/ unless otherwise stated)



| | i) | Attributable income system: the tax rate of first-category applicable on entities will be progressively increased, 21% in 2014, 22.5% in 2015, 24% in 2016, up to 25% in 2017. Its choice is being restricted to companies
whose partners are individuals domiciled or resident in Chile or individuals or legal persons non-domiciled and non-resident in Chile. This system levies the shareholders of Chilean entities with taxes on an
annual basis regardless of any effective distribution of profits from the local entity; and entitles them to use the total taxes paid as income tax fiscal credit.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ii) | Partially integrated system: of first-category taxes applicable on entities will be progressively increased, 21% in 2014, 22.5% in 2015, 24% in 2016, 25.5% in 2017, up to 27% in 2018. Subject to this system are
corporations and entities in which at least one of its owners is not an individual (whether domiciled or not) or non-domiciled legal entity. This system levies the shareholders of Chilean entities that
distribute dividends and entitle them to use such distribution as a fiscal credit at a 65% of the total taxes paid. This limit does not apply to investors with whom Chile had signed double taxation agreements, such as Peru.

| | d) | Changes in the Income Tax Law in Colombia -
| | -- | -------------------------------------------

In December 2014 Law No 1739 was enacted amending
the Tax Code and introducing diverse temporary changes in Income Tax, CREE (Tax on income for equity) and includes the tax on wealth (Impuesto a la Riqueza). Major changes are as follows:



| |  |  | Setting the CREE tax rate at 9% and creating an incremental additional overrate effective until 2018, as follows: for fiscal 2015, 2016, 2017 and 2018 the applicable CREE tax overrate will be 5%, 6%, 8% and 9%,
respectively.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Starting 2015 tax losses can be offset to the CREE taxable amount.
| | - |  | ------------------------------------------------------------------



| |  |  | The tax on wealth levies the wealth owned by an individual or legal entity that are income taxpayers; this is determined on the basis of the gross equity less current debts that are equal to or higher than a
1,000 million Colombian pesos (S/1.1 million approximately) at January 01, 2015.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The tax on wealth rates are marginal and cascaded in ranges of taxable base ranging from 0.2% to 1.15% in 2015, from 0.15% to 1% in 2016 and from 0.05% to 0.4% in 2017.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In December 2016 Law No.1819 was published with another amendment to the tax laws, effective from fiscal 2017. Major changes are as follows:



| |  |  | Income tax rates effective until 2016 (Income tax + CREE+ Overrate + Wealth) are now simplified with one single rate, i.e. 34% income tax rate and a temporary overrate of 6% for fiscal 2017 and an income tax rate of 33%
and a temporary overrate of 4% for fiscal 2018 and onwards on a taxable income of above S/895 thousand (equivalent to COP800 million).
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Colombian taxable income, applicable when there are tax losses, will be subject to a tax base of 4% of the liquid equity (formerly 3%) and will be considered as a
on-account payment of the taxable income.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Tax losses can be offset in the following eight (8) years from the date they were generated.
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | The special rate on dividends and interests obtained by non-domiciled foreign legal entities and individuals will be 5%
| | - |  | -----------------------------------------------------------------------------------------------------------------------

Under Chilean Legislation, when a Company reports tax losses, it can apply for a refund of
first-category taxes paid in prior years up to an amount that equals the taxes that would be levied on the tax losses, provided that no dividends have been distributed on the income obtained from the refund. The amount to be refunded by the Chilean
Tax Authorities is called provisional payment on absorbed profits - PPUA. The Company recognizes income from income tax and an account receivable when applying for this tax refund.

In 2016 the PPUA-derived income is related to the tax losses reported by of subsidiary VyV-DSD. In 2015
this item was related to the tax losses reported by CAM Chile Spa and VyV-DSD, amounting to S/19.4 million and S/21.9 million, respectively.



| | f) | The Groups income tax differs from the theoretical amount that would have resulted from applying the weighted-average income tax rate applicable to the profit reported by of the consolidated companies, as follows:

resident in Peru, Chile and Colombia applied income tax rates of 28%, 24% and 40% respectively (28%, 22.5% and 39% for 2015; 28%, 21% and 34% for 2014). Norvial, GyM Ferrovías, Vesur and GMP (Blocks III and IV) have legal stability agreements
with Peruvian Government, in force for all years preserved. In this sense, the consolidated theoretical amount is obtained as a weighted average pre-tax profit or loss and the applicable income tax rate.

| | h) | Peruvian tax authorities have the right to examine, and, if necessary, amend the income tax determined by the Company in the last four years - from January 1 of the year after the date when the tax returns are
filed (years subject to examination). Therefore, years 2012 through 2016 are subject to examination by the tax authorities. Since differences may arise over the interpretation by the tax authorities of the regulations applicable to the Company, it
is not possible at present to estimate if any additional tax liabilities will arise as a result of any eventual examinations. Any additional tax, fines and interest, if they occur, will be recognized in the results of the period when such
differences with the tax authorities are resolved. Management considers that no significant liabilities will arise as a result of these possible tax examinations. Additionally, income tax returns for fiscal years 2013 to 2014 and those to be filed
for fiscal year 2016 remain open for examination by the Chilean tax authorities who have the right to carry out said examination within the three years following the date the income tax returns have been filed. Fiscal years 2014 and 2015 are open
for tax audit by Colombian tax authorities; fiscal 2016 will also be open for audit. Colombian tax authorities are entitled to audit two consecutive years following the date the income tax returns were filed.

|32 | CONTINGENCIES, COMMITMENTS AND GUARANTEES
|-- | -----------------------------------------



| | a) | Tax contingencies -
| | -- | -------------------



| |  |  | For fiscal 2016 an appeal is in progress with the Peruvian Tax Court and another administrative action with the Judiciary involving the results of tax audits of VAT (IGV) and Income Tax returns performed by the Peruvian
tax authorities for fiscal years 1999 to 2002. The maximum exposure amount is S/5.2 million.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | With respect to our subsidiary GyM S.A., as a result of the tax audits of fiscal 1999, 2001 and 2010, SUNAT issued tax determination and tax penalties resolutions amounting to approximately S/19.1 million
(S/24.5 million as of December 31, 2015):
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In fiscal year 2017, the tax litigation process related to 2001 was
resolved, where the Tax Court orders SUNAT to recalculate the observations, determining an amount lower than initially claimed. Our subsidiary has decided to accept the conclusions of this resolution and submit fractionation requests for the payment
of the debt in reference amounting to S/14.1 million

Likewise, at the end of fiscal year 2017, the contentious-administrative
process related to the 1999 fiscal year was resolved, where the Judicial Branch rejected our arguments and confirmed what was stated by SUNAT. Regarding this process, there was already a contingency provision of S/5 million.

An administrative tax process related to the 2010 fiscal year is still underway, however, its resolution will not imply economic damage since
it corresponds to a greater refund of the balance in favor in 2011, already audited by the Tax Administration



| |  |  | Consortiums in which subsidiary GyM S.A takes part, brought claims with SUNAT against the results of the tax inspection, which had a maximum exposure at December 31, 2016 of S/2.8 million (S/0.8 million
at December 31, 2015).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | GMD and its subsidiaries have tax claims currently in progress involving fiscal years 2002, 2011 and 2012 with a maximum exposure of S/2.7 million at December 31, 2016.

Management expects the outcome of the other court actions will be favorable to the Company
considering their nature and characteristics as well as the opinion of its legal advisor.



| | b) | Other contingencies -
| | -- | ---------------------

Year 2016 -



| | i) | Civil-court lawsuits mainly related to indemnities for damages, contract termination and workplace accidents amounting to S/0.61 million (S/0.15 million attributable to GyM; S/0.19 million attributable to
Concar; S/0.17 million attributable to Viva GyM while the remaining S/0.1 million attributable to GMP and CAM Peru).
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ii) | Contentious administrative lawsuits for S/4 million, of which, S/3.4 million is related to 14 processes of GMP S.A. and Consorcio Terminales, S/0.5 million resulting from an action brought against GyM
Ferrovías for alleged noncompliance with OSITRANs General Rules of Oversight. In addition, it includes S/0.1 million GyM S.A. related to a contentious administrative process.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | iii) | Administrative lawsuits for S/3.29 million, S/0.85 million is related to 24 processes of GMP S.A., Consorcio Terminales and Terminales del Perú; S/2 million involving GyM Ferrovías resulting
from an action brought by OSITRAN, the Municipalities of Villa María del Triunfo and San Juan de Miraflores comprising the property tax; S/0.24 million against Viva GyM for a claim made by the Asociación Peruana de Consumidores y
Usuarios before Indecopi in relation to the Parques del Agustino project; and S/0.2 million involving an action brought against Concesionaria Canchaque for alleged contractual noncompliance with OSITRAN).
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | iv) | Labor lawsuits for a total S/6.12 million (S/5 million comprising actions brought against GyM, S/0.35 million against STRACON GyM; S/0.65 million against GMP, S/0.2 million against GMD S.A., and
the remaining balance of S/0.1 million comprising actions brought against Concar, CAM Colombia and CAM Perú S.A.).
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | v) | Two securities class action have been filed against the Company, an executive and a former executive officers in the Eastern District of New York during the first quarter of 2017. Both complaints allege false and
misleading statements during the class period. In particular, they allege that the Company failed to disclose, among other things, that a) the company knew that its partner Odebrecht was engaged in illegal activities, and b) the Company profited
from such activities in violation of its own corporate governance standards. All parties have agreed to unify the two lawsuits and appoint a single lead plaintiff, with one single council to control the class action. On March 6, 2018, the court
appointed Treasure Finance Holding Corp. as the plaintiffs representative. In addition, the court has established the following schedule: i) on May 4, 2018, consolidation of files; ii) on July 3, 2018, presentation of the request for
dismissal; iii) September 4, 2018, presentation of the opposition to the request for dismissal; and iv) October 3, 2018, submission of allegations by GyM. After this, the court could dismiss the claim or admit it. Management believe that
both of those actions would likely be dismissed by the court for failure to adequately file a claim. Therefore, at the reporting date, we consider the risk of a material loss to the company is not probable.

| | vi) | On March 30, 2017, the minority interest holders of Adexus (Sistemas y Redes S.A. and Asesorías e Inversiones Busso Ltda.) filed three lawsuits against Graña y Montero S.A.A., GMD, Adexus and their
major executives, related to: a) the unenforceability of the Investment Agreement and Shareholders Agreement under the provisions of Law 18.046 (Ley de Sociedades Anónimas in Chile), for a total amount claimed of
US$11.4 million (equivalent to S/38.3 million); b) the declaration of nullity because of fraud of the Investment Agreement and other acts and damages and the order of forced execution of the Investment Agreement, plus damages for a total amount
claimed of US$50 million (equivalent to S/168 million); c) the declaration of nullity of the Shareholders Agreement and its amendments. The parties have responded and counterclaimed and up to date we are waiting for the date of the
Conciliation Hearing. The probability of loss of the present litigations is classified as remote.

|33 | BUSINESS COMBINATIONS
|-- | ---------------------



| | a) | Acquisiton of Adexus S.A. -
| | -- | ---------------------------

In June 2015 the Company acquired 44% interest in the capital
stock of Chilean entity Adexus S.A., which is mainly engaged in providing IT solutions services. At December 31, 2015 the Company arrived at the conclusion that joint control existed and that the joint arrangement qualified as a joint venture;
therefore, the investment was recorded under the equity method of accounting in the consolidated financial statements of the Group (Note 16-b).

In January 2016 the Group acquired an additional interest of 8%, totaling 52% of total interest; the consideration agreed totaled
S/8.3 million which was settled through debt capitalization. This larger interest did not affected the investment classification as a joint venture.

Subsequently, in August 2016, the Group acquired an additional interest of 39.03% to obtain total interest in its capital stock of 91.03%; thus
gaining control over this entity. The consideration agreed totaled S/14 million which was initially stated as debt and then capitalized in the same period.

Losses arising from the re-measurement at fair value of the previously
held interest amounted to S/6.8 million, which was recognized in the statement of income within Other income and expenses, net, at the date of acquisition of that additional interest (Note 29).

Acquisition transaction costs amounting to S/1.4 million were charged to profit or loss within administrative expenses.

Revenue and net losses obtained for the period from the acquisition date to December 31, 2016 were S/113.2 million and
S/3.7 million, respectively. If Adexus had been consolidated from January 1, 2016, the balances of revenue and net losses would have been S/272.7 million and S/20.2 million, respectively.

Provided that the distribution of the consideration is divided between the fair values on a
provisional basis for the 2016 financial statements, the Group will complete the distribution process over a period that should not exceed one year as of the acquisition date of Adexus.

During such review period, additional assets and liabilities will be recognized as they may arise from updated data that may be obtained in
relation with the information that existed at the acquisition date and that does not comprise new incidents occurred after the acquisition date; that is, if the Group were to adjust initial amounts recognized at the business combination dates.



| | b) | Acquisition of Morelco S.A.S. -
| | -- | -------------------------------

In December 23, 2014, through subsidiary GyM S.A. the
Company obtained control of Morelco S.A.S. (Morelco) by acquiring 70.00% of its capital shares. Morelco is an entity domiciled in Colombia that is mainly engaged in providing construction and assembly services. This acquisition is part of the
Groups plan to increase its presence in markets that present high growth potential as in Colombia, and in attractive industries, such as mining and energy.

At December 31, 2014 the Company determined goodwill resulting from this acquisition on the basis of an estimated purchase price of
US$93.7 million (equivalent to S/277.1 million), which included cash payments made for US$78.5 million and cash payable estimated to be US$15.1 million (equivalent to S/45.7 million), which, under the agreement of the parties, would
be defined after a review of the acquirees balance sheet, mainly working capital, cash and financial debt as well as the final carrying amount of the acquirees work backlog. The estimated purchase price was allocated to the provisional
carrying amounts of the assets acquired and the liabilities assumed.

As a result of this allocation, the balance of goodwill was
determined to be US$36.1 million (equivalent to S/105.8 million).

In 2015 as part of the review of the provisional allocation of the
purchase price, the following situations arose:



| | a) | The balance at December 31, 2014 of the consideration payable of US$15 million (equivalent to S/46 million) was adjusted in 2015 to US$9.1 million (S/32 million) as a result of the final determination of
the working capital, cash and financial debt balances, under the purchase agreement. This amount was fully paid in 2015.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | b) | The provisional fair values of certain assets acquired and liabilities assumed were reviewed.
| | -- | ---------------------------------------------------------------------------------------------

As a result of the above, the purchase price was adjusted to US $87.5 million (equivalent to S/258.6 million); the provisional fair values
of certain asset and liabilities were modified, giving rise to an adjustment of goodwill to US$35.2 million (equivalent to S/103 million).

The table below summarizes the consideration paid by Morelco and the determination of the fair value of the assets acquired and liabilities
assumed as well as a non-controlling interest at the date of acquisition:

Acquisition-related costs of S/4.5 million have been recognized to 2014s profits within
administrative expenses.

If Morelco had been consolidated from January 1, 2014 revenue and profit would have been
S/722.57 million and S/80.8 million, respectively.

Put and call options of
non-controlling interest-

Under the shareholder agreement signed for the acquisition of
Morelco, the subsidiary GyM signed a purchase-sale agreement for 30% of Morelcos capital stock held by the non-controlling shareholders. By this agreement, the
non-controlling shareholders obtained a right to sell their shares over a period and for an amount set in the agreement (put option). The period to exercise the option began on the second anniversary of the
acquisition of the option and expires on its tenth anniversary. The option exercise price is based on a EBITDA multiple less the net debt and until months 51 and 63 until from the date of the agreement a minimum amount is set that is based on the
price per share that GyM paid to buy 70% of Morelcos share capital.

On the other hand, the subsidiary GyM obtains call option to buy
those shares over a period of 10 years and at a price that is determined the same way as the put option price is determined, except for the fact the minimum amount is effective for the entire effective period of the option (call option).

Under the IFRS framework, the put option is for the Company an obligation to purchase non-controlling
interest shares, and therefore, the Group recognizes a liability measured on the basis of the present value of that option. Since the Group arrived at the conclusion that as a result of this agreement, it did not obtained the risks and rewards
inherent to the ownership of this share package underlying the option, initial recognition of this liability was a charge to equity of controlling shareholders within other reserves.

The amount of the liability arising from the put option was estimated at the present value of the redemption amounts expected on the basis of
minimum amount of the Morelcos agreement and the exercise rights of the option. The Company expects that purchase options are to be exercised at the date following the date of transfer. The expected redemption of the non-controlling interest is as follows: 41.66% in the second year, 41.66% in the fourth year and the remaining shares will be sold on the fifth anniversary of the option grant date. The discount rate used to
determine the present value of the expected redemption amounts is a risk-free rate available to comparable market participants and indicates the fact that the Group estimates to pay the minimum price of the agreement. At December 31, 2016 the
liability is estimated to be S/109.9 million, using a 0.78% discount rate for the first year, 1.37% discount rate for the third year and 1.76% for the fourth year (at December 31, 2015 it was S/113.5 million, using a 0.65% discount
rate for the first year, 1.31% discount rate for the third year

and 1.76% for the fourth year). In 2016 the changes in the present value of the put option
estimated to be S/0.7 million were recognized in the statement of income (an expense by S/1 million stated within Other income and expenses, net and an income by S/1.7 million stated within Exchange losses,
net, Note 28).



| | c) | Acquisition of Coasin Instalaciones Ltda.
| | -- | -----------------------------------------

In March 2014, through the subsidiary CAM Chile
S.A., the Group acquired control of Coasin Instalaciones Limited with the purchase of 100% of its capital shares. Coasin is an entity incorporated in Chile and is mainly engaged in providing installation and maintenance services for networks and
equipment related to the telecommunications industry.

This acquisition is part of the Groups plan to increase its market share
considering the significant growth potential in Chile, and in other attractive industries, such as utilities.

During a period of twelve
months after the date of acquisition, the Group reviewed the allocation of the purchase price for the acquisition of Coasin Instalaciones Limitada.

Over a period of twelve months after the acquisition, the Group reviewed the allocation of the purchase price and fair values determined
provisionally for certain assets and liabilities. As a result of this process, the balance of goodwill was changed to US$2.2 million (equivalent to S/6.4 million).

|35 | EARNINGS (LOSSES) PER SHARE
|-- | ---------------------------

Basic earnings per share are calculated by dividing the net
profit of the period attributable to common shareholders of the Group by the weighted average number of common shares outstanding during the year. No diluted earnings per common share were calculated because there are no common or investment shares
with potential dilutive effects (i.e., financial instruments or agreements that give the right to obtain common or investment shares); therefore, it is equal to basic earnings per share.

The basic earnings per share are broken down as follows:

|37 | EVENTS AFTER THE DATE OF THE STATEMENT OF FINANCIAL POSITION
|-- | ------------------------------------------------------------



| | a) | Early termination of the GSPs concession agreement -
| | -- | -----------------------------------------------------

According to a notification
issued by the Ministry of Energy and Mines of Peru on January 24, 2017, the early termination of the Concession Contract was declared, based on the provisions of clause 6.7 of the Concession Agreement Improvements to the countrys
energy security and development of the South Peru Gas Pipeline , as GSP failed to certify the financial closing within the established contractual deadline and proceeded to the immediate execution of the performance guarantee. This situation
generated the execution of the counter-guarantees offered by the Group to the company issuing the performance guarantee of the Concession Contract for US $ 52.5 million (S /. 176.6 million) and US $ 129 million (S / 433.3 million). for the
corporate guarantee of the bridge loan granted to GSP.

On October 11, 2017, the agreement was signed for the delivery of the goods of
the Southern Peru Gas Pipeline concession between GSP and the Ministry of Energy and Mines (MEM). As stated in the agreement, GSP delivered most of the Concession Assets in possession to the administrator designated by the MEM for its custody and
conservation. The assets include all the works, equipment and facilities provided for the execution of the project, as well as the engineering studies that were prepared by the concessionaire company.

After the termination of the contract, the Peruvian Government, in accordance with the contract, had to hire an audit entity of recognized
international prestige to calculate the Net Book Value (VCN for its Spanish definition Valor Contable Neto) of the Concession Assets and the subsequent call for up to three public auctions, being the base amount for the first
of them 100% of the VCN, guaranteeing in any case that after the third auction, in case the concession has not been awarded, the payment to GSP would be at least 72.25% of the VCN. Having elapsed more than a year since the termination of the
contract, the Peruvian Government has not taken any action to calculate the VCN and call for auctions. In the opinion of the external and internal legal advisors, since the previous procedure had not been done within the established deadlines, the
Peruvian Government would be obliged to pay GSP 100% of the VCN. Regarding the amount of the VCN there is a previous calculation commissioned by GSP reviewed by an audit firm as an independent expert as of December 31, 2016, which determined a
VCN of US $ 2,602 million.

GSP as of December 4, 2017 entered into a bankruptcy proceeding that will be carried out by
the National Institute for the Defense of Competition and Intellectual Protection of Peru (hereinafter, INDECOPI), and the Group registered a claim for accounts receivable in 2017 charge for US $ 434,465.77 and the fiduciary based in its capacity as
administrator accounts receivable amounting US $ 169,287,006

(All amounts expressed in thousands of S/ unless otherwise stated)



Based on the amount of the VCN, applying the payments foreseen in the insolvency proceedings,
the subordination contracts and the loan cession agreements between the Group and GSP partners, the assumption that an international arbitration will be required to achieve the payment by the Government, and, in accordance with the conclusions of
the internal and external legal advisors, it is estimated that the international arbitration would take approximately 5 years to resolve. This is why an impairment of the investment was recorded, which includes a finance update and estimation of
costs for US $ 202.3 million before taxes at the income statement, as indicated in notes 13. c) and 16.

In addition, considering the
early termination of the GSP contract, the Group evaluated the impairment of the financial statements of CCDS. As a result, a net loss before taxes of S / 15.2 million was determined (Note 5.1-f), that
was recognized in gross profit in the Engineering and Construction segment.

Same as in the Emergency Decree 003, Law 30737 (see note 1 c)
iii) in its First Section, includes Odebrecht and its related companies, which include GSP. According to this Law, GSP will not be able to make transfers abroad, will require the consent of the Ministry of Justice in case it wishes to sell assets
and must deposit the proceeds of such sale in a guarantee trust. Likewise, the entities of the Government that must make some payment to the entities included in the Law, must withheld according to the contract 10%, equivalent to the net profit
margin, and deposit it in the aforementioned trust in guarantee. According to our internal and external legal advisors, Government payment for the VCN is not within the scope of the withholding, as this payment does not include net profit margin,
nor is a sale of assets.



| | b) | Renegotiations of liabilities and credit lines -
| | -- | ------------------------------------------------



| | i) | Credit Suisse Syndicated Loan
| | -- | -----------------------------

On June 27, 2017, the Company renegotiated the terms of
this loan to clear breaches related to the termination of the GSP concession. The new terms establish repayment by December, 2020. See Note 19-i)



| | ii) | GSP Performance Guarantee
| | --- | -------------------------

On March 31, 2017, the Company renegotiated the terms for
repayment obligations regarding the proportional share of the performance guarantee issued in connection with the GSP concession (Note 22). The new terms require repayment by June 30, 2018, with interest accrual 6% per year, and provide a
security interest over our shares in CAM, and lien on certain assets cash flows.
