                                     PART I

ITEM 1. BUSINESS
(In thousands of dollars except per share data)

  Unless the context otherwise requires, references to 1998, 1997 and 1996 are
references to the Corporation's fiscal years ended November 30, 1998, 1997 and
1996, respectively.

I.  GENERAL

  The Corporation is an international provider of a broad range of design,
engineering, construction, construction management, facilities management,
environmental remediation and mining services to diverse public and private
sector clients. Through its various operating units, the Corporation:

  .  Provides design, construction and renovation services for plants and
     facilities in the general manufacturing, chemical, petrochemical, food and
     beverage, pharmaceuticals, high-technology and institutional buildings
     markets;

  .  Provides a full range of engineering and construction services to power
     generation utilities, including construction of new plants, retrofitting of
     existing plants and decommissioning and decontamination of nuclear plants
     that have reached the end of their operating lives;

  .  Provides total facilities management to industrial clients, including
     maintenance, engineering and construction, and operations and logistics
     management at manufacturing plants and related facilities and at toll
     roads;

  .  Provides facilities management and environmental remediation services to
     governmental agencies, such as the Department of Energy and the Department
     of Defense;

  .  Provides design, engineering, construction and construction management
     services for infrastructure projects in the transportation, marine and
     water resources markets, including highway, bridge, railroad, airport,
     marine port and water distribution and storage facilities projects; and

  .  Provides contract mining services in the fossil fuel and industrial
     minerals markets, together with technical and engineering services such as
     resource evaluation, geologic modeling, mine planning and development,
     equipment selection and remediation.

                                      I-1
<PAGE>
 
  In providing  its services, the Corporation enters into three basic types of
contracts:

  .  Fixed-price or lump-sum contracts providing for a  fixed price for the
     total amount of work to be performed;

  .  Unit-price contracts providing for a fixed price for each unit of work
     performed; and

  .  Cost-type contracts providing for reimbursement of costs plus a fee.

  Both anticipated income and economic risk are greater under fixed-price and
unit-price contracts than under cost-type contracts. Engineering, construction
management and environmental and hazardous substance remediation contracts are
typically awarded on a cost-plus-fee basis. See "Risk Factors - The
Corporation's fixed-price and unit-price contracts place the risk of increased
project costs on the Corporation."

  The Corporation also participates often as sponsor and manager in construction
joint ventures that are formed for the purpose of bidding, negotiating and
completing specific projects. In addition, the Corporation participates in the
following mining ventures: Westmoreland Resources, Inc., a coal mining company
in Montana, and MIBRAG mbH, a company that operates lignite coal mines and power
plants in Germany. See Note 6. "Ventures" of Notes to Consolidated Financial
Statements in Part II of this Annual Report on Form 10-K .

  The Corporation was originally formed in Delaware on April 28, 1993 under the
name Kasler Holding Company to become the parent company of WCG Holdings, Inc.
("WCG") and Kasler Corporation ("Kasler"),  which were active in the
infrastructure, contract mining, environmental remediation, commercial
construction and construction materials markets. In April 1996, the name of the
Corporation was changed from Kasler Holding Company to Washington Construction
Group, Inc.

  On September 11, 1996, the Corporation acquired the net assets and the
engineering and construction operations of Morrison Knudsen Corporation, a
Delaware corporation ("Old MK"), in a transaction structured as a merger of Old
MK with and into the Corporation, and changed its name to Morrison Knudsen
Corporation. The acquisition of Old MK was an integral part of the
reorganization of Old MK pursuant to a plan of reorganization (the "Plan") filed
by Old MK in the United States Bankruptcy Court for the District of Delaware
(the "Bankruptcy Court").  The Plan was confirmed by the Bankruptcy Court on
August 26, 1996, and became effective concurrently with the merger on September
11, 1996. The Corporation has no remaining obligations under the Plan.

   The Corporation's executive offices are located at Morrison Knudsen Plaza,
Boise, Idaho 83729, and its telephone number is (208) 386-5000.

II.  OPERATING UNITS

  The  Corporation's operations have been conducted through three market-driven
operating units: The Engineers and Constructors Group based in Cleveland, Ohio,
and the Heavy Civil Construction Group and the Mining Group based in Boise,
Idaho. In January 1999, the Corporation announced the consolidation of the Heavy
Civil Construction Group and the Mining Group into "Morrison Knudsen Contractors
Group."

ENGINEERS AND CONSTRUCTORS GROUP:

  The Engineers and Constructors Group, which is the largest and most diverse of
the Corporation's operating groups, is comprised of five divisions:

  . Industrial/Process Division: This division primarily targets Fortune 100
    clients and provides design and construction services for new construction
    or renovations of plants and facilities in the general manufacturing,
    chemical, petrochemical, food and beverage, pharmaceuticals, high-technology
    and institutional-buildings markets.

                                      I-2
<PAGE>
 
  .  Energy Division: This division offers a full range of engineering and
     construction services to power generation utilities. These services include
     construction of power plants, installation of flue-gas scrubber systems and
     plant retrofit projects such as the replacement of steam generators in
     nuclear power plants, a division specialty. This division also provides
     decommissioning and decontamination of nuclear power plants that have
     reached the end of their operating lives.

  .  Operating and Maintenance Division: This division primarily provides total
     facilities management services to industrial clients. These services
     include maintenance, engineering and construction and operations and
     logistics management at manufacturing plants and related facilities and at
     toll roads. These services are typically outsourced by firms that want to
     focus internal resources on plant production.

  .  Transportation Division: This division, which operates as "MK Centennial
     Engineering," specializes in engineering and construction management of
     highway, bridge, railroad, airport and water resource infrastructure
     projects.

  .  Federal Programs Division: This division specializes in the operation and
     environmental remediation of government facilities, primarily for the
     Department of Energy and the Department of Defense .

The Engineers and Constructors Group also performs private sector environmental
remediation work, builds and operates chemical weapons demilitarization
facilities and constructs infrastructure projects internationally.

HEAVY CIVIL CONSTRUCTION GROUP:

  The Heavy Civil Construction Group, which is one of the largest organizations
of its kind in the United States, provides services both as a general contractor
and in a design-build capacity.  This group targets infrastructure projects in
the transportation, marine and water resources markets. This group also provides
site development at mine, industrial, commercial, recreational and large
residential sites.

MINING GROUP:

  The Mining Group is an international provider of contract mining services  for
the fossil fuel and industrial minerals markets. In addition,  this group offers
a full range of technical and engineering services, including resource
evaluation, geologic modeling, mine planning and development, environmental
permitting, equipment selection and remediation.

III.  GOVERNMENT CONTRACTS AND BACKLOG

  Government contracts are a significant part of the Corporation's business. See
"Risk Factors - The government can audit and potentially disallow claims for
compensation under the Corporation's government contracts, and can terminate
such contracts without cause."

  Backlog consists of uncompleted portions of engineering and construction
contracts, including the Corporation's proportionate share of construction
joint-venture contracts and its share of revenues from mining service contracts
and ventures for the next five years. Backlog of all uncompleted contracts at
November 30, 1998 totaled $2.7 billion compared with November 30, 1997 backlog
of $3.7 billion as originally reported and $2.8 billion as restated. (See the
following paragraph for a description of the principal reasons for this decrease
in backlog.) Approximately $657 million or 25% of the backlog at November 30,
1998 was comprised of U.S. government contracts which are subject to termination
by the government, $402 million of which had not been funded. Terminations for
convenience of the government generally provide for recovery of contract costs
and related earnings. Approximately $1.2 billion or 44% of 1998 year-end backlog
is expected to be recognized as revenue in 1999.

  Although backlog reflects business which is considered to be firm,
cancellations or scope adjustments may occur. Backlog has been adjusted to
reflect known project cancellations, deferrals and revisions in project scope
and cost, both 

                                      I-3
<PAGE>
 
upward and downward. In the third quarter of 1998, the Corporation reduced
backlog by approximately $102 million reflecting the reduction in scope of an
environmental contract for the U.S. government. In anticipation of its pending
acquisition of certain businesses presently owned and operated by CBS
Corporation (see Note 14. "Acquisition of Westinghouse Businesses" of Notes to
Consolidated Financial Statements) which are engaged in the performance of
significant government contracts, and to reduce the exposure to material
adjustments due to scope and funding issues on other government contracts
included in reported backlog, the Corporation made an assessment of its policy
of including in backlog unfunded U.S. government contracts. During the fourth
quarter of 1998, the Corporation adopted a new policy which excludes from
backlog unfunded government contracts which management is not highly confident
will be funded within two years. Backlog has been reduced by $843 million in the
fourth quarter, primarily as a result of the adoption of this new policy. The
reduction in backlog is not an impairment of the revenues or earnings potential
of the Corporation. However, there can be no assurance that future contract
cancellations or modifications will not reduce backlog and future revenues.

--------------------------------------------------------------------------
</TABLE>

*Amounts have been restated to conform with the adoption of the new policy in
1998. The Corporation typically has, at any given point in time, 25% to 35%
additional unreported backlog representing awarded yet unfunded contracts and
any mining business beyond five years.

IV.  EMPLOYEES

  The Corporation's total worldwide employment varies widely with the volume,
type and scope of operations under way at any given time and other factors.

  At November 30, 1998, the Corporation employed a total of approximately 9,000
employees -- including 5,800 salaried and project direct-hire craft employees
and 3,200 employees covered by collective bargaining agreements.

V.  RAW MATERIALS

  Raw materials and components necessary for the rendering of construction,
environmental and hazardous substance remediation and contract mining services
are generally available from numerous sources. The Corporation does not foresee
any unavailability of raw materials and components which would have a material
adverse effect on its business in the near term.

VI.  COMPETITION

  Engineering and construction is a highly competitive business, particularly
for contracts obtained by competitive bidding. The Corporation competes based
primarily on price, reputation and reliability with other general and specialty
contractors, both foreign and domestic. Success or failure in the engineering
and construction industry is, in large measure, based upon the ability to
compete successfully for contracts and to provide the engineering, planning,
procurement, management and project financing skills required to complete them
in a timely and cost-efficient manner. See "Risk Factors - The Corporation is
engaged in highly competitive businesses and must bid against competitors to
obtain engineering, construction and service contracts."

                                      I-4
<PAGE>
 
VII.  ENVIRONMENTAL MATTERS

  The Corporation's environmental and hazardous substance remediation and
contract mining services involve risks of liability under federal, state and
local environmental laws and regulations, including the Comprehensive
Environmental Response, Compensation, and Liability Act ("CERCLA"). The
Corporation performs environmental remediation at Superfund sites as a response
action contractor for the Environmental Protection Agency (the "EPA") and, in
such capacity, is exempt from liability under any federal law, including CERCLA,
unless its conduct was negligent; moreover, the Corporation may be entitled to
indemnification from the United States against liability arising out of
negligent performance of work in such capacity. A determination that the
Corporation is liable under environmental laws and regulations for the cost of
environmental remediation due to its performance of contract mining or
environmental remediation could have a material adverse effect on the financial
position, results of operations and cash flows of the Corporation. Amendments
to, or more stringent implementation of, current environmental laws and
regulations also could have such adverse effects.

  For additional information regarding environmental matters, see "Summitville
environmental matters" and "Other environmental matters" in Note 13.
"Contingencies and Commitments" of Notes to Consolidated Financial Statements.
See also "Risk Factors - The Corporation could be subject to liability under
environmental laws."

VIII.  RISK FACTORS

  The Corporation and its businesses are subject to a number of risks, including
those enumerated below. Any or all of such risks could have a material adverse
effect on the business, financial condition, results of operations and cash
flows of the Corporation and on the market price for the Corporation's
securities. See also "Note Regarding Forward-Looking Information."

THE CORPORATION IS ENGAGED IN HIGHLY COMPETITIVE BUSINESSES AND MUST BID AGAINST
COMPETITORS TO OBTAIN ENGINEERING, CONSTRUCTION AND SERVICE CONTRACTS:

  The Corporation is engaged in highly competitive businesses, particularly
those portions relating to engineering, construction and other service contracts
that are awarded through competitive bidding processes. The Corporation competes
with other general and specialty contractors, both foreign and domestic,
including large international contractors and small local contractors. Certain
competitors have greater financial and other resources than the Corporation
which, in some instances, could give them a competitive advantage over the
Corporation.

ECONOMIC DOWNTURNS AND REDUCTIONS IN GOVERNMENT FUNDING COULD HAVE A NEGATIVE
IMPACT ON THE CORPORATION'S BUSINESSES:

  Demand for the services offered by the Corporation has been, and is expected
to continue to be, subject to significant fluctuations due to a variety of
factors beyond its control, including economic conditions.  During economic
downturns, the ability of both private and governmental entities in targeted
markets to make capital expenditures on infrastructure improvement may decline
significantly. There can be no assurance that economic or political conditions
generally will be favorable or that there will not be significant fluctuations
adversely affecting the industry as a whole or key markets targeted by the
Corporation. In addition, the Corporation's operations are in part dependent
upon governmental funding of infrastructure and environmental projects.
Significant changes in the level of government funding of these projects could
have an unfavorable impact on the operating results of the Corporation.

THE CORPORATION'S FIXED-PRICE AND UNIT-PRICE CONTRACTS PLACE THE RISK OF
INCREASED PROJECT COSTS ON THE CORPORATION:

  The Corporation's fixed-price and unit-price contracts involve risks relating
to the inability of the Corporation to receive additional compensation in the
event that the costs of performing such contracts prove to be greater than
anticipated. The Corporation's cost of performing such contracts may be greater
than anticipated due to uncertainties inherent in estimating contract completion
costs, contract modifications by customers, failure of subcontractors and 

                                      I-5
<PAGE>
 
joint-venture partners to perform and other unforseen events and conditions. Any
one or more of these risks could result in reduced profits or increase losses on
a particular contract or contracts.

THE GOVERNMENT CAN AUDIT AND POTENTIALLY DISALLOW CLAIMS FOR COMPENSATION UNDER
THE CORPORATION'S GOVERNMENT CONTRACTS, AND CAN TERMINATE SUCH CONTRACTS WITHOUT
CAUSE:

  Government contracts are a significant part of the Corporation's business. In
addition to other significant government contracts, contracts and subcontracts
with the United States Department of Energy accounted for approximately 14% of
the Corporation's revenues for the year ended November 30, 1998. See Note 12.
"Geographic and Customer Information" of Notes to Consolidated Financial
Statements. The Corporation has a number of cost reimbursement contracts with
various agencies of the U.S. government. Allowable costs under these contracts
are subject to audit by the U.S. government. To the extent that such audits
result in determinations that costs claimed as reimbursable are not allowable
costs or were not allocated in accordance with federal government regulations,
the Corporation could be required to reimburse the U.S. government for amounts
previously paid. See "Government Contracts and Backlog" for the relative
significance of U.S. government contracts included in year-end 1998 backlog and
related risks. See Note 13.  "Contingencies and Commitments -- Contract related
matters" of Notes to Consolidated Financial Statements.

  The Corporation has a number of contracts and subcontracts with various
agencies of the U.S. government, principally for environmental remediation and
restoration work, which extend beyond one year and for which government funding
has not yet been approved. There can be no assurance that such funding will be
approved. All contracts with agencies of the U.S. government and some commercial
and foreign contracts are subject to unilateral termination at the option of the
customer.  In the event of a termination, the Corporation would not receive
projected revenues or profits associated with the terminated portion of such
contracts.

THE CORPORATION'S BUSINESSES INVOLVE MANY PROJECT-RELATED AND CONTRACT-RELATED
RISKS:

  The engineering and construction business is subject to a variety of project-
related risks, including changes in political and other circumstances,
particularly since contracts for major projects are performed over extended
periods of time. These risks include the failure of applicable governing
authorities to take certain necessary actions, opposition by third parties to
particular projects and the failure to obtain adequate financing for particular
projects. Due to these factors, losses on a particular contract or contracts
could occur, and the Corporation could experience significant changes in
operating results on a quarterly or annual basis.

  Because of the size and complexity of major infrastructure projects, a
relatively small number of projects may provide a significant percentage of the
Corporation's revenue in a given year. The loss of one or more major contracts
or the inability of the Corporation to perform profitably under one or more
major contracts, could have a material adverse effect on the Corporation's
financial condition, results of operations and cash flows.

  The Corporation may also be adversely affected by various risks and hazards,
including industrial accidents, labor disputes, geological conditions,
environmental hazards, weather and other natural phenomena such as earthquakes
and floods.

THE CORPORATION'S SUCCESS DEPENDS ON ATTRACTING AND RETAINING QUALIFIED
PERSONNEL IN A COMPETITIVE ENVIRONMENT:

  The Corporation is dependent upon its ability to attract and retain highly
qualified managerial, technical and business development personnel. Competition
for such personnel is intense. There can be no assurance that the Corporation
can retain its key managerial, technical and business development personnel or
that it can attract, assimilate or retain such personnel in the future.

                                      I-6
<PAGE>
 
THE CORPORATION'S INTERNATIONAL OPERATIONS INVOLVE SPECIAL RISKS:

  The Corporation pursues project opportunities throughout the world through
foreign and domestic subsidiaries as well as agreements with foreign joint-
venture partners. These foreign operations are subject to special risks,
including:

  .  Uncertain political and economic environments,

  .  Potential incompatibility with foreign joint-venture partners,

  .  Foreign currency controls and fluctuations,

  .  Civil disturbances, and

  .  Labor strikes.

  Events outside of the Corporation's control may limit or disrupt operations,
restrict the movement of funds, result in deprivation of contract rights,
increase foreign taxation or limit repatriation of earnings.  In addition, in
certain cases applicable law and joint-venture or other agreements may provide
that each joint-venture partner is jointly and severally liable for all
liabilities of the venture. See Note 12. "Geographic and Customer Information"
of Notes to Consolidated Financial Statements.

THE CORPORATION COULD BE SUBJECT TO LIABILITY UNDER ENVIRONMENTAL LAWS:

  The Corporation is subject to a variety of environmental laws and regulations
governing, among other things, discharges to air and water, the handling,
storage, and disposal of hazardous or solid waste materials and the remediation
of contamination associated with releases of hazardous substances.  Such laws
and regulations and the risk of attendant litigation can cause significant
delays to a project and add significantly to its cost. Violations of these
environmental laws and regulations could subject the Corporation and its
management to civil and criminal penalties and other liabilities. There can be
no assurance that such laws and regulations will not become more stringent, or
more stringently implemented, in the future.

  Various federal, state and local environmental laws and regulations, as well
as common law, may impose liability for property damage and costs of
investigation and cleanup of hazardous or toxic substances on property currently
or previously owned by the Corporation or arising out of the Corporation's waste
management activities.  Such laws may impose responsibility and liability
without regard to knowledge of or causation of the presence of the contaminants,
and the liability under such laws is joint and several.  The Corporation has
potential liabilities associated with its past waste management and contract
mining activities and with its current and prior ownership of certain property.
See "Business -- Environmental Matters" and "Other environmental matters" in
Note 13. "Contingencies and Commitments" of Notes to Consolidated Financial
Statements.
 
THE FAILURE OF THE CORPORATION OR ITS BUSINESS PARTNERS TO BE YEAR 2000
COMPLIANT COULD HAVE ADVERSE CONSEQUENCES:

  Like most other companies and organizations, the Corporation relies on
computer-based technology in the conduct of its business. The Corporation has
been and is continuing to address the impact of the  "Year 2000" issue. This
issue is the result of computer programs that were written using two digits
rather than four to define calendar years. These programs may fail to properly
differentiate between calendar years in the twenty-first century and calendar
years in the twentieth century (e.g., they may recognize a date using "00" as
the year 1900 rather than the year 2000). If not corrected, the Year 2000 issue
could result in complete system failures or miscalculations causing significant
disruption of normal business activities.

                                      I-7
<PAGE>
 
  The Corporation has been and is continuing to assess and resolve Year 2000
issues associated with its material internal systems and its material third-
party relationships. Although the Corporation believes that its Year 2000
readiness efforts are designed to appropriately identify and address those Year
2000 issues that are within the Corporation's control, there can be no assurance
that the Corporation's efforts will be fully effective. The newness and
complexity of the issues presented and the Corporation's dependence on the
technical skills and preparedness of third parties are among the factors that
could cause the Corporation's efforts to be less than fully effective. Moreover,
Year 2000 issues present many risks that are simply beyond the Corporation's
control, such as the potential effects of Year 2000 issues on the economy in
general and on the Corporation's business partners, vendors, subcontractors and
customers in particular. See "The Year 2000 Issue" in Item 7. "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

ONE SHAREHOLDER'S LARGE OWNERSHIP INTEREST IN THE CORPORATION, PROVISIONS OF
DELAWARE LAW AND THE CORPORATION'S ORGANIZATIONAL DOCUMENTS COULD INHIBIT A
TAKEOVER OF THE CORPORATION:

  As of November 30, 1998, Dennis R. Washington, the Chairman of the Board of
Directors of the Corporation, beneficially owned 37.88% of the 53,352,410 shares
of outstanding common stock of the Corporation. As of February 3, 1999, Mr.
Washington is also President and Chief Executive Officer of the Corporation. Mr.
Washington's substantial ownership interest and certain provisions of the
Delaware General Corporation Law, the Corporation's Certificate of Incorporation
and Bylaws and certain agreements to which the Corporation is a party, may have
the effect of delaying, deterring or preventing a change in control of the
Corporation. In addition, the Certificate of Incorporation authorizes the
issuance of up to 100,000,000 shares of common stock and 10,000,000 shares of
preferred stock of the Corporation. The Board of Directors has the power to
determine the price and terms under which any such additional capital stock may
be issued and to fix the terms of such preferred stock, and existing
stockholders of the Corporation will not have preemptive rights with respect
thereto.

ITEM 2.  PROPERTIES
(In thousands of dollars)

  At November 30, 1998, the Corporation owned more than 3,500 units of heavy and
light mobile construction, environmental remediation and contract mining
equipment.

  The Corporation does not own significant real property for operations other
than certain land and improvements in Highland and Petaluma, California. At
November 30, 1998, the Corporation had real estate held for sale in  Nevada. The
two principal administrative office facilities in Boise, Idaho, and Cleveland,
Ohio, of approximately 214,700 square feet and 246,700 square feet,
respectively, are leased under long-term, noncancelable leases expiring in 2003
and 2010, respectively. The Corporation's long-term aggregate rental obligations
for the Boise and Cleveland facilities under these noncancelable leases for each
of the next five years approximate $6,970, $6,970, $7,495, $7,545 and $6,911,
respectively.

  Annual rental payments  for real estate and equipment leased by the
Corporation during the year ended November 30, 1998 aggregated $52,067. See Note
13. "Contingencies and Commitments -- Long-term leases" of Notes to Consolidated
Financial Statements.

  Construction, environmental remediation and mining equipment and leased
administrative and engineering facilities are considered by the Corporation to
be well maintained and suitable for current operations.

-----------------------------------------------------------------------------
</TABLE>
REVENUE AND GROSS PROFIT:

  Revenue for the fourth quarter and year ended November 30, 1998 increased
$104.0 million to $543.3 million and $184.9 million to $1,862.2, respectively,
compared to $439.3 million and $1,677.3 million for the comparable periods in
1997. These increases were principally due to an increase in the volume of
industrial/process, operation and maintenance and energy  project work executed
by the Engineers and Constructors Group. Revenue increased slightly for the
fourth quarter and year ended November 30, 1998 in the Heavy Civil Construction
Group and for the fourth quarter in the Mining Group over the comparable periods
in 1997. The increase in the Corporation's  revenue for the year ended November
30, 1998 was partially offset by a decrease in revenue from the Mining Group,
which experienced a lower demand for coal production and power generation from
the MIBRAG mbH mining venture in Germany during the first nine months of 1998
and the completion of a significant long-term mining contract in the third
quarter of 1997. MIBRAG mbH increased coal production in the fourth quarter of
1998 over each of the previous three quarters of the year.

  Gross profit for the fourth quarter and year ended November 30, 1998 increased
$2.8 million to $24.1 million and $7.2 million to $86.5 million, respectively,
compared to $21.3 million and $79.3 million for the comparable periods of 1997.
Gross profit for the fourth quarter of 1998 included favorable results from each
of the Corporation's operating groups. During the fourth quarter of 1997, the
Corporation recognized a $3.9 million pretax loss on a large, fixed-price joint-
venture contract. Gross profit for the year ended November 30, 1998 included
improved profitability in the Heavy Civil Construction Group and a $5.7 million
settlement on an environmental contract. These increases were partially offset
by lower demand for coal production and power generation from the MIBRAG mbH
mining venture during the first nine months of the year, the recognition of a
loss related to start up difficulties on a fixed-price construction contract and
$5.4 million net losses related to the write-off of investment in a solvent
extraction facility and a related contract to treat contaminated soil. Gross
profit for the year ended November 30, 1997 included earnings from a significant
long-term mining contract completed in the third quarter of 1997, offset by
provisions for losses at completion for contracts in progress of $9.5 million
and a $3.9 million pretax loss on a large, fixed-price joint-venture contract.

  Gross profit as a percentage of revenue for the fourth quarter and year ended
November 30, 1998 was 4.4% and 4.6%, respectively, compared to 4.8% and 4.7% for
the same periods in 1997. The decrease in gross profit percentage in 1998 was
primarily due to a higher proportion of revenue attributable to the Engineers
and Constructors Group, 

                                      II-3
<PAGE>
 
which had lower operating margins than the comparable period of 1997. The
Engineers and Constructors Group typically executes cost-plus contracts which
have less risk but lower margins. Gross profit percentage for the fourth quarter
of 1998 increased slightly from 4.3% for the third quarter of 1998.

  The Corporation's operating margins often vary between periods due to inherent
risks and rewards on fixed-price contracts causing unexpected gains and losses
on contracts. Operating margins may also vary between periods due to changes in
the mix and timing of contracts executed by the Corporation, which contain
various risk and profit profiles and uncertainties inherent in the estimation
process. The Corporation strives to offset certain of the risks inherent in its
contracts through geographic, customer and risk diversification.

  At November 30, 1998, backlog of $2,680 million was comprised of $901 million
(34%) of revenue from fee-type contracts and $1,779 million (66%) of revenue
from fixed-price contracts and the Corporation's share of revenue from mining
ventures.

GENERAL AND ADMINISTRATIVE EXPENSES:

  General and administrative expenses for the fourth quarter and year ended
November 30, 1998 increased $.5 million and $1.3 million, respectively, compared
to the comparable periods of 1997. The increase is attributable to an increase
in implementation costs of new computer information systems for financial, human
resource and payroll  functions and the reengineering of the Corporation's
financial processes. The Corporation's implementation costs are anticipated to
continue through 1999. The Corporation expects the system implementation and
reengineering will improve the efficiency and cost of processing accounting and
financial data,  but anticipates that the initial cost savings will be somewhat
offset by expenses associated with training costs and amortization of the new
computer software.

COST IN EXCESS OF NET ASSETS ACQUIRED ("GOODWILL"):

  Goodwill amortization for the fourth quarter and year ended November 30, 1998
was $.9 million and $3.6 million, respectively, principally reflecting the
amortization of the $124.1 million of goodwill recorded in connection with the
acquisition of Old MK. The Corporation allocated the purchase price of Old MK to
the assets acquired and liabilities assumed, including preacquisition
contingencies, on the basis of estimated fair values at September 11, 1996.
Resolution and revaluation of certain preacquisition contingencies and tax law
changes extending the net operating loss ("NOL") carryforward period from 15 to
20 years resulted in an adjustment to goodwill in the third quarter of 1997.
During the fourth quarter of 1998, management evaluated the likelihood of the
future realization of the tax benefits of deductible temporary differences and
NOL carryforwards relating to Old MK and concluded, based on available evidence,
that it is more likely than not that a portion of the tax benefits previously
reserved would be realized. This conclusion resulted in an increase in deferred
tax assets and a decrease in recorded goodwill of $20 million at November 30,
1998. The decrease in goodwill will reduce future annual goodwill amortization
by $.5 million. A further adjustment to deferred tax assets and related goodwill
may be likely in connection with the Corporation's pending acquisition of
certain businesses presently owned and operated by CBS Corporation. See Note 14.
"Acquisition of Westinghouse Businesses" of Notes to Consolidated Financial
Statements.

INVESTMENT INCOME:

  Investment income for the fourth quarter and year ended November 30, 1998
decreased $2.7 million and $3.3 million, respectively, from the comparable
periods of 1997 due to a decrease in interest recognized in 1997 from U.S.
federal income tax refunds received in January 1998 and a note receivable
collected in October 1997. These reductions in investment income were partially
offset by increased interest income on corporate cash in short-term asset
management accounts.

INTEREST EXPENSE:

  Interest expense for the fourth quarter and year ended November 30, 1998 of
$.2 million and $.9 million, respectively, was comparable to interest expense
incurred for the same periods of 1997. Interest expense consists 

                                      II-4
<PAGE>
 
primarily of periodic amortization of prepaid underwriting fees and quarterly
commitment fees in connection with the Corporation's five-year, $200 million
revolving loan and letter of credit facility obtained in the fourth quarter of
1996.

OTHER INCOME (EXPENSE), NET:

  Other income (expense)  for the fourth quarter and year ended November 30,
1998, of $1.5 million and $3.8 million, respectively, reflects the recognition
of $1.1 million and $3.2 million of income associated with the settlement of the
Corporation's defined benefit pension plan obligation. Final distribution of
surplus plan assets to eligible plan participants  is expected to be made in
early 1999.

  Other income (expense) for the quarter ended November 30, 1997 includes (i) a
$1.7 million income adjustment of the accrued pension benefit obligation
reflecting the  estimate of termination benefits to be settled with cash
proceeds from liquidation of plan assets and (ii) $1.9 million of expensed
acquisition costs associated with the Corporation's cancellation of the proposed
acquisition of Montana Resources, Inc. In addition, for the year ended November
30, 1997, the Corporation recognized an $.8 million loss on the sale of an
equity investment in a foreign bank and a $.6 million gain on adjustment of
insurance premiums paid in prior periods.

INCOME TAX EXPENSE:

  The effective tax rate for the fourth quarter and year ended November 30, 1998
was 44%, compared to 48% and 47% in the comparable periods of 1997, principally
due to a decrease in foreign tax expense and a lower proportion of non-
deductible expenses to pretax income. The effective tax rate is higher than the
U.S. federal statutory rate of 35% because of state income taxes and foreign
income taxes not currently eligible for use as credits against U.S. federal
income taxes and non-deductible expenses. It is anticipated that future foreign
income tax will be eligible for use as credits against U.S. federal income taxes
in 1999 and future periods.

1997 COMPARED TO 1996

THE CONSOLIDATED RESULTS OF OPERATIONS FOR THE YEAR ENDED NOVEMBER 30, 1996
INCLUDE THE RESULTS OF OLD MK FOR THE PERIOD FROM SEPTEMBER 12 TO NOVEMBER 30,
1996.

REVENUE AND GROSS PROFIT:

  Revenue and gross profit for the year ended November 30, 1997 increased
$1,018.2 and $46.0, respectively, compared to 1996 primarily due to the
acquisition of Old MK on September 11, 1996, which was accounted for as a
purchase. Gross profit, as a percent of revenue for the year, was 4.7%  for 1997
compared to 5.1% for 1996. During 1997, the Corporation's gross profit
benefitted from strong performances on several contracts which more than offset
the losses incurred on certain fixed-price contracts. In the fourth quarter of
1997, the Corporation assumed sponsorship of a large, fixed-price joint venture
due to the bankruptcy of the previous sponsor and recorded a $3.9 million pretax
loss because of the uncertainties on the project, including change orders and
potential project claims.

GENERAL AND ADMINISTRATIVE EXPENSES:

  General and administrative expenses for the year ended November 30, 1997
increased $.3 million compared to the year ended November 30, 1996. The
Corporation incurred approximately $1 million in expenses related to an
enterprise-wide implementation of new computer information systems for the
Corporation's financial, human resource and payroll functions.

IMPAIRMENT OF LONG-LIVED ASSETS:

  In 1996, the Corporation recognized impairment losses of $18.2 million on
certain real property held for sale or use and operating assets of a subsidiary
held for sale.

                                     II-5
<PAGE>
 
COST IN EXCESS OF NET ASSETS ACQUIRED ("GOODWILL"):

  Goodwill amortization for the year ended November 30, 1997 increased to $3.6
million from $1.2 million in 1996, reflecting the $124.1 million of goodwill
recorded in connection with the acquisition of Old MK. The Corporation allocated
the purchase price of Old MK to the assets acquired and liabilities assumed,
including preacquisition contingencies, on the basis of estimated fair values at
September 11, 1996. Resolution and revaluation of certain preacquisition
contingencies and the recent tax law change extending the NOL carryforward
period from 15 to 20 years, resulted in a net decrease in goodwill of $1.0
million in the third quarter of 1997. The extension of the NOL carryforward
period resulted in a decrease to goodwill of $19.7 million after adjusting the
valuation allowance related to the deferred tax asset. This decrease was offset
by an accrual for preacquisition contingencies of $18.7 million, primarily for
legal proceedings.

INVESTMENT INCOME:

  Investment income was comprised of (i) earnings from cash equivalents,
securities jointly held with customers as contract retentions and securities
available for sale, and (ii) interest on a note receivable collected in the
fourth quarter of 1997 and U.S. federal income tax refund receivables.
Investment income for the year ended November 30, 1997 increased $5.4 million
from 1996 principally due to interest recognized on U.S. federal income tax
refunds and earnings from securities available for sale.

INTEREST EXPENSE:

  Interest expense for the year ended November 30, 1997 decreased $.1 million
compared to 1996. Interest expense for 1997 consisted primarily of periodic
amortization of prepaid underwriting fees and quarterly commitment fees in
connection with the Corporation's five-year, $200 million revolving loan and
letter of credit facility obtained in the fourth quarter of 1996.

OTHER INCOME (EXPENSE), NET:

  Other expense for the year ended November 30, 1997 included (i) $1.7 million
income adjustment of the accrued pension benefit obligation reflecting the
estimate of termination benefits to be settled with cash proceeds from
liquidation of plan assets and (ii) $1.9 million of expensed acquisition costs
associated with the Corporation's cancellation of the proposed acquisition of
Montana Resources, Inc. In addition, the Corporation recognized an $.8 million
loss on the sale of an equity investment in a foreign bank and a $.6 million
gain on adjustment of insurance premiums paid in prior periods.

INCOME TAX EXPENSE:

  The effective tax rate for the year ended November 30, 1997 was 47%. The
effective rate was greater than the U.S. federal statutory rate of 35%,
primarily due to the impact of state and foreign income taxes and non-deductible
goodwill amortization. For the year ended November 30, 1996, the Corporation
recognized an income tax benefit of $.5 million which reflected recoverable
federal income taxes, net of foreign and state income tax expense.

FINANCIAL CONDITION AND LIQUIDITY

  The Corporation has three principal sources of near-term liquidity: (1)
existing cash and cash equivalents; (2) cash generated by its operations; and
(3) revolving loan borrowings under its credit facility. Management believes the
Corporation's liquidity and capital resources should be sufficient to meet its
reasonably foreseeable working capital, capital expenditure and other
anticipated cash requirements.

 Financing activities                   (29,734)    3,102
----------------------------------------------------------
</TABLE>

  Cash and cash equivalents increased $13.8 million during the year ended
November 30, 1998 to $67.1 million at November 30, 1998. This increase reflects
net cash provided from operating activities of $71.7 million offset by net cash
used in investing and financing activities of $28.1 million and $29.7 million,
respectively. The favorable operating cash flow for 1998 was attributable to
improved profitability and a greater focus on cash flow and working capital
management. Cash provided by operations also included $25.2 million from an
income tax refund and related interest; of which $18.0 million was applied as
required to the redemption  of the Corporation's Series A redeemable preferred
stock. These increases were partially offset by additional capital requirements
for three significant construction joint ventures in the Heavy Civil
Construction Group. Cash provided or used from operating activities from period
to period is affected to a large extent by the mix, timing, state of completion
and commercial terms of engineering and construction contracts which is
reflected in changes in net operating assets and liabilities. The Corporation
anticipates that the execution of existing backlog can be managed through future
operating cash flows and available cash and cash equivalents without need for
additional capital resources.

  Net cash used for investing activities in 1998 of $28.2 million included net
$20.5 million of property and equipment acquisitions, the net purchase of $5.9
million of securities available for sale in connection with the Corporation's
self-insured risk management program and $4.0 million primarily for the purchase
of a ready-mix concrete business offset by $2.8 million in cash proceeds from
the sale of a non-core business.

  Cash used in financing activities in 1998 of $29.7 million included $18.0
million for the redemption of the Corporation's Series A redeemable preferred
stock and $12.8 million for repurchase of 973,100 shares of the Corporation's
outstanding common stock. The Corporation received authorization in January 1998
to repurchase, in open market transactions, block trades or otherwise up to 2
million shares of the Corporation's outstanding common stock to counteract the
dilutive effect of the issuance of stock under its stock option plans, and up to
2.765 million of its warrants to purchase common stock. Subject to market
conditions and other factors, these purchases may be commenced, discontinued and
resumed from time to time without prior notice. It is anticipated that future
purchases will be funded from available cash and equivalents and operating cash
flows. Depending upon conditions in capital markets and other factors, the
Corporation may consider the possible issuance of long-term debt or other
securities.

  The Corporation anticipates capital expenditures for major construction
equipment of approximately $25 million 

                                      II-7
<PAGE>
 
during 1999 for normal replacement and to meet equipment requirements of its
expanding business.

  The Corporation has a five-year, $200.0 million revolving loan and letter of
credit facility from the Bank of Montreal. Under the credit facility,
outstanding revolving loan borrowings are limited to $125.0 million. During
1998, the Corporation had no outstanding borrowings under the facility and was
in compliance with its covenants, the most restrictive of which is fixed charge
coverage.

  The Corporation is subject to foreign currency translation and exchange
issues, primarily with regard to its mining venture, MIBRAG mbH, in Germany. At
November 30, 1998, the cumulative adjustments for translation losses net of
related income tax benefits was $3.0 million. The Corporation realized a pretax
gain on foreign currency exchange transactions of $358 thousand for the year
ended November 30, 1998. The Corporation endeavors to enter into contracts with
foreign customers with repayment terms in U.S. currency as a protection from
foreign exchange risk.

  As discussed in Note 14. "Acquisition of Westinghouse Businesses," the
Corporation intends to fund its share of the purchase price for certain
businesses presently owned and operated by CBS Corporation and its share of the
working capital requirements of such businesses using existing financing
facilities, additional financing facilities for which the Corporation has
received commitments or an offering of senior unsecured notes, together with
cash on hand and cash from other operations. The terms of such additional
borrowings have not yet been finalized.

  The Corporation may, from time to time, pursue opportunities to complement
existing operations through business combinations and participation in ventures,
which may require additional financing and utilization of the Corporation's
capital resources.

THE YEAR 2000 ISSUE

  The Year 2000 issue  is the result of computer programs written and electronic
circuitry that use two digits rather than four to define calendar years. These
programs may fail to properly differentiate between calendar years in the
twenty-first century and calendar years in the twentieth century (e.g., they may
recognize a date using "00" as the year 1900 rather than the year 2000). If not
corrected, the Year 2000 issue could result in complete system failures or
miscalculations causing significant disruption of normal business activities.
The Year 2000 issue affects virtually all companies and organizations, including
the Corporation.

  The Corporation employs a number of information technology ("IT") systems in
its operations including, without limitation, computer networking systems,
financial systems and other similar systems. Throughout its operations, the
Corporation also employs numerous non-IT devices such as building security and
safety devices and other devices containing embedded electronic circuits. Both
IT systems and non-IT devices are subject to potential failure or error due to
the Year 2000 issue.

  The Corporation has developed  and implemented a strategic plan (the "Year
2000 Project") to achieve Year 2000 readiness. The Year 2000 Project's
activities are intended to remediate the Year 2000 issue in all major categories
of systems and electronic devices in use by the Corporation, including IT
systems, non-IT devices and supply chain relationships so that the Corporation
may continue its operations without interruption or with minimal disruption. It
also includes communication with critical third parties such as clients,
vendors, subcontractors and other business partners to determine the expected
degree of Year 2000 compliance of those parties, and to monitor their progress
towards Year 2000 readiness. The Year 2000 Project includes the following
phases: (1) awareness, (2) inventory, (3) assessment, (4) remediation, (5)
testing/validation and (6) return to production. Progress reports on the Year
2000 Project are presented regularly to the Corporation's senior management and
periodically to the Audit Committee of the Board of Directors.

  Because of the scope of its operations, the Corporation believes it is
impractical to seek to eliminate all potential Year 2000 problems before they
arise. As a result, the Corporation expects that its Year 2000 assessments and
corrections will include ongoing remedial efforts into the year 2000. The
Corporation is using a risk-based analysis of 

                                      II-8
<PAGE>
 
its operations to identify those items that are critical to the Corporation and
at risk. Critical items are being identified through the "inventory" phase of
the Year 2000 Project.

  The Corporation is in various "inventory," "assessment" and "remediation"
phases with regard to its state of readiness related to non-IT devices
containing embedded circuitry and issues related to third parties with whom the
Corporation has material relationships. The Corporation is in various states of
the "inventory," "assessment," "remediation" and "testing/validation" phases
with regard to its IT systems.  As part of the Year 2000 Project regarding IT
systems, the Corporation continues implementing new or upgraded Year 2000
compliant systems for financial information, human resources and payroll.  These
systems  are expected to be completed in July, 1999.

  The Corporation is corresponding with its major clients and joint-venture and
other business partners, and with all vendors and subcontractors that have been
determined, through practical risk assessment techniques, to be  critical to the
Corporation, in order to determine the Year 2000 readiness or progress of those
entities and to assess any related risks.

  As part of the Year 2000 Project, the Corporation is exploring alternative
solutions and developing contingency plans to address the possibility that the
Corporation and third parties with whom it has material relationships will not
be fully Year 2000 ready on a timely basis. Such plans have not yet been fully
developed, and the Corporation will continue to develop them as necessary to
address each area of Year 2000 risk. Completion of the Year 2000 Project,
including the development of contingency plans, is expected by September 30,
1999.

  The Corporation's Year 2000 Project utilizes both internal and external
resources. The total cost of the Corporation's activities to achieve Year 2000
readiness is currently estimated at approximately $21.6 million. As of November
30, 1998, the direct costs incurred by the Corporation to remediate Year 2000
issues were approximately $6.7 million.

   Although the Corporation believes that its Year 2000 readiness efforts are
designed to appropriately identify and address those Year 2000 issues that are
within the Corporation's control, there can be no assurance that the
Corporation's efforts will be fully effective. The newness and complexity of the
issues presented and the Corporation's dependence on the technical skills and
preparedness of third parties are among the factors that could cause the
Corporation's efforts to be less than fully effective. Moreover, Year 2000
issues present many risks that are simply beyond the Corporation's control, such
as the potential effects of Year 2000 issues on the economy in general and on
the Corporation's business partners, vendors, subcontractors and customers in
particular.

  While the Corporation believes that the impact of any individual Year 2000
failure will most likely be localized and limited to specific facilities or
operations, the Corporation is not yet able to assess the likelihood of
significant business interruptions occurring in one or more of its operations
around the world. Such interruptions could prevent the Corporation, at least
temporarily, from delivering contractual services. Furthermore, it has been
widely reported that significant litigation is expected to occur related to
business interruptions caused by Year 2000 failures. It is uncertain whether, or
to what extent, the Corporation will be affected by such litigation. The failure
of the Corporation, its clients (including U.S. government agencies), vendors,
joint-venture partners or others upon whom the Corporation relies to achieve
Year 2000 readiness could adversely  affect the Corporation's business
operations, which could have a material adverse effect on the Corporation's
business, financial condition and results of operations.

  The foregoing disclosure is based upon the Corporation's current expectations,
estimates and projections, which could ultimately be found to be inaccurate.
Because of uncertainties and circumstances beyond the Corporation's control, the
actual effects of Year 2000 issues on the Corporation may be different than the
foregoing assessment. See "Note Regarding Forward-Looking Information."

ENVIRONMENTAL CONTINGENCY

  From July 1985 to June 1989, a subsidiary of the Corporation performed certain
contract mining services at the 

                                     II-9
<PAGE>
 
Summitville mine near Del Norte, Colorado. The EPA has notified the Corporation
and approximately 20 other parties that each is a potentially responsible party
("PRP") with regard to hazardous substances generated or disposed of at the
Summitville Mine Superfund Site ("Site"). The EPA has not commenced any
litigation or other proceedings against the Corporation. The Corporation has had
only preliminary discussions with the EPA but has been informally advised that
the EPA does not consider the Corporation eligible for a de minimis settlement
(the basis for settlement by several PRPs considered to have contributed less
than 3% volume and toxicity of the hazardous substances at the Site).

  According to a report published in August 1996, the EPA estimated that the
total remediation costs incurred and to be incurred at the Site will be $120.0
million. The Corporation is not a party to any agreement regarding an allocation
of responsibility, and the EPA has not made an allocation of responsibility
among the PRPs. The Corporation's share, if any, of the aggregate environmental
liability associated with the Site is not presently determinable and depends
upon, among other things, the manner in which liability may be allocated to or
among the Corporation or other PRPs associated with the Site, the efficacy of
any defenses that the Corporation or such other PRPs may have to any assertion
of liability, the willingness and ability of such other PRPs to discharge such
liability as may be allocated to them and the outcome of any negotiations or
settlement discussions between the Corporation and the EPA and/or such other
PRPs. Accordingly, no remediation costs have been accrued at November 30, 1998.
Management believes that the ultimate resolution of this matter could have a
material adverse effect on the Corporation's financial position and could
materially and adversely effect its results of operations and cash flows in one
or more periods.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
(IN THOUSANDS)

  The Corporation's exposure to market risk for changes in interest rates
relates primarily to the Corporation's short-and long-term investment portfolio
and debt obligations. The Corporation's short-term investment portfolio consists
primarily of highly liquid instruments with maturities of one month or less. The
Corporation's long-term investment portfolio consists primarily of high-quality
debt instruments with maturities under 10 years and an average maturity of 3.5
years. These long-term instruments are held to fund potential workers
compensation obligations of the Corporation. The Corporation seeks to match the
maturities of these instruments as closely as possible with its anticipated
workers compensation obligations and to hold these instruments to maturity in
order to minimize market risk exposure. As of November 30, 1998, the Corporation
had $39,644 of short-term investments classified as cash equivalents and $45,985
in its long-term investment portfolio.

  The Corporation may from time to time effect borrowings under its bank credit
facility for general corporate purposes, including working capital requirements,
capital expenditures and acquisitions. Borrowings under the bank credit facility
bear interest at the applicable LIBOR or base rate and, therefore, the
Corporation is subject to fluctuations in interest rates. As of November 30,
1998, the Corporation had no outstanding debt obligations.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Morrison Knudsen Corporation

  In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, stockholders' equity and cash flows
present fairly, in all material respects, the financial position of Morrison
Knudsen Corporation and subsidiaries (the "Corporation") at November 30, 1998
and 1997, and the results of their operations and their cash flows for each of
the three years in the period ended November 30, 1998, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Corporation's management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which 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
audits provide a reasonable basis for the opinion expressed above.

  As discussed in Note 3 to the consolidated financial statements, the
Corporation changed its method of accounting for impairment of long-lived assets
in 1996 to conform with Statement of Financial Accounting Standards No. 121.

  As discussed in Note 13 to the consolidated financial statements, the
Corporation has been named as a potentially responsible party at the Summitville
Mine Superfund Site. The Corporation's share, if any, of the ultimate
environmental liability at the site is not presently determinable and,
accordingly, no remediation costs have been accrued in the accompanying
financial statements.

MORRISON KNUDSEN CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(IN THOUSANDS OF DOLLARS EXCEPT SHARE DATA)

  The term "Corporation" as used in this Annual Report includes Morrison Knudsen
Corporation and its consolidated subsidiaries unless otherwise indicated.

1.  SIGNIFICANT ACCOUNTING POLICIES

BUSINESS:

  The Corporation is a provider of (i) engineering and construction management
services to industrial companies, electric utilities and public agencies, (ii)
comprehensive environmental and hazardous substance remediation services to
governmental and private-sector clients, (iii) diverse heavy construction
services for the highway, airport, water resource, railway and commercial
building industries, and (iv) mine planning, engineering and contract mining
services for diverse customers. In providing such services, the Corporation
enters into three basic types of contracts: fixed-price or lump-sum contracts
providing for a fixed price for the total amount of work to be performed, unit-
price contracts providing for a fixed price for each unit of work performed, and
cost-type contracts providing for reimbursement of costs plus a fee.  Both
anticipated income and economic risk are greater under fixed-price and unit-
price contracts than under cost-type contracts. Engineering, construction
management and environmental and hazardous substance remediation contracts are
typically awarded on a cost-plus-fee basis.

  The Corporation also participates in construction joint ventures, often as
sponsor and manager of projects, which are formed for the sole purpose of
bidding, negotiating and completing specific projects. In addition, the
Corporation participates in the following mining ventures: Westmoreland
Resources, Inc., a coal mining company in Montana, and MIBRAG mbH, a company
that operates lignite coal mines and power plants in Germany.

PRINCIPLES OF CONSOLIDATION:

  The consolidated financial statements include the accounts of the Corporation
and all of its majority-owned subsidiaries. Investments in mining ventures and
all joint ventures are accounted for by the equity method. The Corporation's
proportionate share of construction joint-venture and mining venture revenue,
cost of revenue and gross profit (loss) is included in the consolidated
statements of operations. Intercompany accounts and transactions have been
eliminated.

REVENUE RECOGNITION:

  Revenue is generally recognized on a percentage-of-completion method.
Completion is generally measured for engineering and construction contracts
based on the proportion of costs incurred to total estimated contract costs. For
certain long-term contracts involving mining, environmental and hazardous
substance remediation, completion is measured on estimated physical completion
or units of production.

  Revenue recognition on certain fixed-price construction contracts begins when
progress is sufficient to estimate the probable outcome or on the completed
contract method if the probable outcome cannot be reasonably estimated. The
cumulative effect of revisions to contract revenue and completion costs,
including incentive awards, penalties, change orders and anticipated losses, is
recorded in the accounting period in which the amounts are known and can be
reasonably estimated.  Such revisions could occur at any time, and the effects
could be material. Revenue from claims are recorded, to the extent that contract
costs have been incurred, when it is probable that the claim will result in
additional contract revenue and it can be reliably estimated.

  The Corporation has a history of making reasonably dependable estimates of the
extent of progress towards completion, contract revenue and contract completion
costs on its long-term engineering and construction contracts. 

                                     II-19
<PAGE>
 
However, due to uncertainties inherent in the estimation process, it is possible
that actual completion costs may vary from estimates in the near term.

USE OF ESTIMATES:

  The preparation of the Corporation's consolidated  financial statements in
conformity with generally accepted accounting principles necessarily requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the balance sheet date and the reported amounts of revenue and costs during the
reporting periods. Actual results could differ in the near term from those
estimates.

UNBILLED RECEIVABLES:

  Unbilled receivables at November 30, 1998 arise from the use of the
percentage-of-completion method of accounting, cost reimbursement-type contracts
and the timing of billings. Substantially all of the unbilled receivables at
November 30, 1998 are expected to be billed and collected within one year.

CLASSIFICATION OF CURRENT ASSETS AND LIABILITIES:

  The Corporation includes in current assets and liabilities amounts realizable
and payable under engineering and construction contracts that extend beyond one
year. Accounts receivable at November 30, 1998 include approximately $2,180 of
contract retentions which are not expected to be collected within one year. At
November 30, 1998 accounts receivable include $1,931 of short-term marketable
securities jointly held with customers as contract retentions, the market value
of which approximated the carrying amounts. The Corporation recognizes interest
income from marketable securities as earned. Advances from customers are non-
interest bearing.

CASH EQUIVALENTS:

  Cash equivalents consist of liquid securities with original maturities of
three months or less readily convertible to known amounts of cash.

CREDIT RISK CONCENTRATION:

  The Corporation, by policy, limits the amount of credit exposure to any one
financial institution and places investments with financial institutions
evaluated as highly creditworthy. Concentrations of credit risk with respect to
accounts receivable and unbilled receivables are believed to be limited due to
the number, diversification and character of the obligors and the Corporation's
credit evaluation process. Typically, the Corporation has not required
collateral for such obligations, but can place liens against property, plant or
equipment constructed if a default occurs. Historically, the Corporation has not
incurred any material credit-related losses.

COST IN EXCESS OF NET ASSETS ACQUIRED:

  Cost in excess of net assets acquired in business combinations ("goodwill") is
amortized using the straight-line method over 40 years. The carrying value of
goodwill is reviewed for impairment on a quarterly basis. If impairment is
indicated by the facts and circumstances, an impairment loss will be recognized
based on a comparison of the carrying value of the long-lived assets and
associated goodwill with the undiscounted cash flow of such assets. The carrying
amount of the goodwill identifiable with such assets will be eliminated before
recognition of impairment of the related long-lived assets and identifiable
intangibles.

PROPERTY AND EQUIPMENT:

  Property and equipment is stated at cost. Major renewals and improvements are
capitalized, while maintenance and 

                                     II-20
<PAGE>
 
repairs are expensed when incurred. Depreciation of construction equipment is
provided on straight-line and accelerated methods, after an allowance for
estimated salvage value, over estimated lives of two to 10 years. Depreciation
of buildings is provided on the straight-line method over estimated lives of 10
to 20 years, and improvements are amortized over the shorter of the asset life
or lease term. Depreciation of equipment, principally computer systems, is
provided under the straight-line method generally over three to five years. Upon
disposition, cost and related accumulated depreciation of property and equipment
are removed from the accounts and the gain or loss is reflected in results of
operations.

FOREIGN CURRENCY TRANSLATION:

  The functional currency for foreign operations is generally the local
currency. Translation of assets and liabilities to U.S. dollars is based on
exchange rates at the balance sheet date. Translation of revenue and expenses to
U.S. dollars is based on a weighted-average exchange rate during the period.
Translation gains or losses, net of income tax effects, are reported as a
component of stockholders' equity for foreign subsidiaries. Because of the
short-term duration of construction and engineering projects, related
translation gains or losses are recognized currently. Gains or losses from
foreign currency transactions are included in the results of operations of the
period in which the transaction is completed.

ENVIRONMENTAL LIABILITIES:

  Accruals for estimated costs of response actions for environmental matters are
recorded when it is probable that a liability has been incurred and the amount
of the liability can be reasonably estimated. On a quarterly basis, the
Corporation reviews estimates of costs of response actions at various sites,
including sites in respect of which government agencies have designated the
Corporation as a potentially responsible party. Accrued liabilities may be
discounted and are exclusive of claims for recovery, if any. However, due to
uncertainties inherent in the estimation process, it is  possible that actual
results may vary from estimates in the near term.

INCOME TAXES:

  Deferred income tax assets and liabilities are recognized for the effects of
temporary differences between the carrying amounts and the income tax basis of
assets and liabilities using enacted tax rates. A valuation allowance is
established when it is more likely than not that net deferred tax assets will
not be realized. Tax credits are recognized in the year they arise.

INCOME (LOSS) PER SHARE:

  Basic income (loss) per share is based on the weighted-average number of
outstanding common shares during the applicable period. Diluted income (loss)
per share is based on the weighted-average number of outstanding common shares
plus the weighted-average number of potential outstanding common shares. The
additional weighted-average number of potential outstanding common shares for
purposes of computed diluted earnings per share consisted solely of stock
options for all periods presented. Income (loss) per share is computed
separately for each quarterly and annual period presented.

RECLASSIFICATIONS:

  Certain reclassifications have been made in prior period financial statements
to conform to the 1998 presentation.

2.  BUSINESS COMBINATION

  On September 11, 1996, the Corporation (which was then known as Washington
Construction Group, Inc.) acquired the net assets and the engineering and
construction operations of Morrison Knudsen Corporation ("Old MK") for $221,736,
and changed its name to Morrison Knudsen Corporation.

                                     II-21
<PAGE>
 
  The purchase price consisted of (i) $13,300 of cash, (ii) 24,161,421 newly
issued shares of common stock of the Corporation valued at $180,364 in the
aggregate, or $7.465 per share, (iii) 1,800,000 newly issued shares of preferred
stock valued at $18,000, (iv) warrants to purchase 2,952,848 shares of the
Corporation's common stock at $12.00 per share valued at $6,564, and (v) $3,508
of acquisition costs. The acquisition of Old MK was structured as a merger of
Old MK with and into the Corporation and was accounted for using the purchase
method of accounting. The purchase price was allocated to the assets acquired
and liabilities assumed based on estimated fair values at September 11, 1996.
The consolidated results of operations for periods subsequent to September 11,
1996 reflect the merged operations. The cost in excess of the net assets
acquired is being amortized under the straight-line method over 40 years.

  The following unaudited pro forma information presents the Corporation's
consolidated results of operations as if the acquisition of Old MK had occurred
on December 1, 1995 and after giving effect to certain adjustments, including
amortization of goodwill, depreciation expense, reduction in investment income
and related tax effects. The unaudited pro forma results of operations for 1996
include Old MK's results of operations for the eleven months ended November 30,
1996. The pro forma results of operations for 1996 reflect certain adjustments
made in 1997 to reflect revenue on mining ventures consistent with the 1997
presentation and to eliminate certain after tax losses on disposal of assets and
professional fees. Such pro forma information does not purport to be indicative
of operating results that would have been reported had the acquisition of Old MK
occurred on December 1, 1995 or of future operating results.

3.  ADOPTION OF ACCOUNTING PRINCIPLE

  During 1998, the Corporation adopted Statement of Financial Accounting
Standards No. 128 Earnings Per Share ("SFAS No. 128") which changed the standard
for computing and presenting earnings per share ("EPS"). Basic EPS excludes
dilution and is computed by dividing net income by the weighted-average number
of shares outstanding for the period. Diluted EPS is computed by dividing net
income by the sum of the weighted-average number of shares outstanding plus the
weighted-average number of potential common shares outstanding. Potential common
shares consist of shares issuable upon the exercise of stock options and
warrants. Earnings per share computations exclude stock options and potential
shares for stock purchase warrants to the extent that their effect would be
antidilutive.

  During 1998, the Corporation also adopted the provisions of Statement of
Position ("SOP") 98-1 Accounting for Costs of Computer Software Developed or
Obtained for Internal Use issued by the American Institute of Certified Public
Accountants. The SOP provides guidance on accounting for the costs of computer
software developed or obtained for internal use. In general, the SOP calls for
expensing software costs incurred in the preliminary project stage and post-
implementation/operation stage and the capitalization of software costs incurred
during the application development stage, including payroll and payroll-related
costs for employees who are directly associated with the 

                                     II-22
<PAGE>
 
project.

  In the third quarter of 1996, the Corporation adopted Statement of Financial
Accounting Standards No. 121 Accounting for the Impairment of Long-Lived Assets
and Long-Lived Assets to be Disposed of , which requires that long-lived assets
and certain identifiable intangible assets be periodically reviewed for
impairment. The impairment loss on long-lived assets aggregating $18,200 in 1996
was comprised of the following:

  (i) The Corporation's Board of Directors approved a plan to offer for sale
  certain assets of a non-core subsidiary with a carrying amount of $17,486 at
  August 31, 1996. The Corporation recognized an estimated impairment loss of
  $6,500 to reduce the carrying amount of the assets to estimated fair value.

  (ii) Land previously held primarily for lease with a carrying amount of $8,266
  at August 31, 1996 was reclassified to land held for sale. The Corporation
  recognized an estimated impairment loss of $5,600 and established a new
  carrying amount of $2,666 at August 31, 1996, based upon an appraisal of the
  current fair value net of the estimated improvement and disposal costs
  required for a near-term bulk sale of the land.

  (iii) As of August 31, 1996, the Corporation recognized an estimated
  impairment loss of $6,100 on the land and buildings in Highland, California,
  which comprised the Corporation's headquarters prior to relocation of the
  headquarters to Boise, Idaho. The loss reflects the change in use and the
  impairment of the $7,016 carrying amount of the Highland property. The
  impairment loss was estimated based on an appraisal of the current fair value.

4. RECENTLY ISSUED ACCOUNTING STANDARDS

  In June 1997, the Financial Accounting Standards Board issued Statement No.
130 Reporting Comprehensive Income ("SFAS No. 130"). SFAS No. 130 establishes
standards for the reporting and display of comprehensive income but does not
effect the current principles of measurement of revenue. Comprehensive income is
defined as the change in equity of a business enterprise during a period from
transactions and other events and circumstances from non-owner sources. The
adoption of SFAS No. 130 is effective for the Corporation  commencing with the
quarter ending February 28, 1999.

  In June 1997, the Financial Accounting Standards Board issued Statement No.
131 Disclosures about Segments of an Enterprise and Related Information ("SFAS
No. 131"). SFAS No. 131 requires publicly-held companies to report segment and
other financial information which is utilized by the chief operating decision
maker and to reconcile the segment information to financial statement amounts.
Specific information to be reported for individual segments includes profit or
loss, certain revenue and expense items and total assets. SFAS No. 131 is
effective for the Corporation commencing with the year ending November 30, 1999.

  In February 1998, the Financial Accounting Standards Board issued Statement
No. 132 Employers' Disclosures about Pensions and Other Postretirement Benefits
- an amendment of FASB Statements No. 87, 88 and 106 ("SFAS No. 132"). SFAS No.
132 revises and standardizes the disclosure requirements for pensions and other
postretirement benefits, requires additional information on changes in the
benefit obligations and fair values of plan assets and eliminates certain
disclosures previously required. SFAS No. 132 does not change the measurement or
recognition of those plans. SFAS No. 132 is effective for the Corporation
commencing with the year ending November 30, 1999.

  In June 1998, the Financial Accounting Standards Board issued Statement No.
133 Accounting for Derivative Instruments and Hedging Activities ("SFAS No.
133"). SFAS No. 133 establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts and for hedging activities. The statement requires that an
entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. The
Corporation is currently evaluating the effect of SFAS No. 133 will have on
future results of operations and financial position. Implementation of SFAS No.
133 is required commencing with the first quarter of 2000.

5.  SECURITIES AVAILABLE FOR SALE

  Securities available for sale are reported at fair value and consisted
primarily of debt securities at November 30, 1998. Gross unrealized gains were
$1,459 and losses were $157 at November 30, 1998. Gross unrealized gains were
$732 and losses were $182 at November 30, 1997. Unrealized gains and losses, net
of income tax effects, are reported as a component of stockholders' equity. Cost
is determined using the specific identification method for purposes of
calculating realized gains and losses. Securities available for sale are held in
a captive insurance subsidiary which insures workers' compensation risks of the
Corporation. Securities available for sale having a fair value of $3,443 at
November 30, 1998 are pledged as collateral for the Corporation's  reimbursement
obligations in respect of letters of credit issued at the Corporation's request
by third parties. Maturity, fair value and cost of securities held for sale were

MINING VENTURES:

  At November 30, 1998, the Corporation had ownership interests in two mining
ventures, MIBRAG mbH (33%) and Westmoreland Resources, Inc.  ("Westmoreland
Resources") (20%). On September 30, 1996, the Corporation sold a 4% ownership
interest in Westmoreland Resources to Westmoreland Coal Company ("Westmoreland
Coal") thereby reducing its ownership interest to 20%. The Corporation provides
contract mining services to these ventures.

  Undistributed earnings from mining ventures totaled $19,295 at November 30,
1998.

  On December 23, 1996, Westmoreland Coal and four subsidiaries, including
Westmoreland Resources, filed for protection under Chapter 11 of the United
States Bankruptcy Code. Effective at the beginning of July 1998, the Corporation
temporarily suspended recording its equity in the income of Westmoreland
Resources pending the outcome of the proceedings. Subsequently, Westmoreland and
its creditors compromised and resolved their differences and, on December 23,
1998, the Chapter 11 bankruptcy case was dismissed. As a result, the
Westmoreland mining contracts with the Corporation remain in full force and
effect and the Corporation's equity interest in Westmoreland Resources is
unaffected.

7.  ASSETS HELD FOR SALE

  At November 30, 1998, assets held for sale are stated at the lower of cost or
fair value less cost of disposal and are comprised of the net assets of a
subsidiary. The Corporation is unable to predict disposal dates. Operations of
the subsidiary resulted in revenue of $20,200 and $5,300, and net losses of $12
and $937 for 1998 and 1997, respectively. During 1998, land held for sale was
sold at approximate book value of $2,758. During 1997, a 29.5% stock ownership
interest in a foreign bank which had a carrying amount of $5,244 at November 30,
1996 was sold at a loss of $833. In 1996, the Corporation recognized aggregate
impairment losses of $12,100 on assets held for sale and $6,100 on assets held
for use.

8.  CREDIT FACILITIES

  On October 31, 1996, the Corporation obtained from the Bank of Montreal a
five-year, $200,000 revolving loan and letter of credit facility  (the
"Facility"). Revolving loan borrowings under the Facility are limited to
$125,000. On October 8, 1997, the Facility was extended for an additional year
to October 2002. Annually thereafter, the Facility may be extended by an
additional year upon mutual approval of the bank and the Corporation.

  Substantially all of the assets of the Corporation and certain of its material
domestic subsidiaries are pledged  to collateralize the Corporation's
obligations under the Facility. The Facility covenants require the maintenance
of financial ratios, the most restrictive of which is fixed charge coverage and
minimum levels of net worth, and place limitations on additional indebtedness,
guarantees, liens, investments and  other matters. At November 30, 1998, the
Corporation had no outstanding borrowings under the Facility and was in
compliance with the covenants. The Corporation is not restricted from paying
dividends unless an event of default exists.

  The Facility provides for loans bearing interest, payable quarterly, at the
applicable LIBOR rate or the base rate, as defined, plus an additional margin.
The additional margin ranges from 3/4% to 1 1/8% for the LIBOR rate and zero to
1/4% for the base rate, based on the ratio of earnings before interest, taxes,
depreciation and amortization to the Corporation's funded debt. In 1996, the
Corporation paid a $1,100 underwriting fee to the bank and is required to pay
annual/quarterly commitment and letter of credit fees.

</TABLE>

  At November 30, 1998, the Corporation had consolidated regular tax net
operating loss carryforwards for federal, state and foreign tax purposes of
approximately $211,137, $194,654 and $3,775, respectively, which expire in the
years 2000 through 2012. In addition, the Corporation had federal alternative
minimum tax credits of $13,731 at November 30, 1998 which carry forward
indefinitely. The $91,987 valuation allowance reduces these net operating loss
carryforwards and other deferred tax assets to a level which management believes
will, more likely than not, be realized based on estimated future taxable
income. The net decrease of $20,000 in the valuation allowance at November 30,
1998 resulted from an evaluation of the likelihood of the future realization of
deductible temporary differences and net 

                                     II-27
<PAGE>
 
operating loss carryforwards of Old MK. The reduction in the valuation allowance
was recorded as a reduction of goodwill related to the acquisition of Old MK.
Any future reduction in the valuation allowance related to tax assets acquired
at September 11, 1996 will result in a reduction of goodwill. The valuation
allowance may be increased based on the occurrence of future events, and any
such increase could be material. Years prior to 1994 are closed to examination
for federal tax purposes. Management believes that adequate provision has been
made for probable tax assessments.

  Income tax expense (benefit) differed from income taxes at the U.S. federal
statutory tax rate of 35% as follows:

  Nondeductible expenses (nontaxable income), net was comprised principally of
goodwill amortization and the nondeductible portion of meals and entertainment
expenses.

  Income (loss) before income taxes was comprised of a domestic source income of
$40,366 and foreign source income of $27,039 in 1998, domestic source income of
$28,725 and foreign source income of $31,171 in 1997 and a domestic source loss
of $(6,406) and foreign source income of $1,132 in 1996.

10.  BENEFIT PLANS

PENSION PLAN:

  The Corporation terminated its defined benefit pension plan in 1997. During
1998, a settlement of the plan's accumulated vested termination benefit
obligation was effected through a combination of lump-sum cash payments and the
purchase of a nonparticipating group annuity contract. As a result of this
termination, other income of  $3,161 was recognized during 1998. At November 30,
1998, approximately  $4,348 in excess plan assets remain in trust and are
expected to be distributed equally after payment of final plan expenses to
eligible plan participants early in 1999. All of these remaining excess assets
are invested in cash equivalents pending this final distribution.

MULTIEMPLOYER PENSION PLANS:

  The Corporation participates in and makes contributions to numerous
construction-industry multiemployer pension plans. Generally, the plans provide
defined benefits to substantially all employees covered by collective bargaining
agreements. Cost of the plans was $18,871 in 1998, $16,098 in 1997 and $4,972 in
1996. Under the Employee Retirement Income Security Act, a contributor to a
multiemployer plan is liable, upon termination or withdrawal from a plan, for
its proportionate share of a plan's unfunded vested liability. The Corporation
currently has no intention of withdrawing from any of the multiemployer pension
plans in which it participates.

  Participants do not accrue any service cost under the plans. There was no
interest expense associated with the pension liability for former non-employee
directors in 1998, 1997 and 1996, as the full, undiscounted liability is
included in the accumulated vested benefit obligation ("ABO"). Pension expense
(consisting entirely of interest on the unfunded current and former employee
ABO) for 1998, 1997 and 1996 was $928, $955 and $207.

POSTRETIREMENT HEALTH CARE PLAN:

  The Corporation succeeded Old MK as sponsor of an unfunded plan to provide
certain health care benefits for employees of Old MK who retired before July 1,
1993, including their surviving spouses and dependent children. Employees who
retired after July 1, 1993 are not eligible for company subsidized
postretirement health care benefits. The plan was amended in past years, and the
Corporation reserves the right to amend or terminate the postretirement health
care benefits currently provided under the plan and may increase retirees' cash
contributions at any time.

  The unrecognized prior service cost is being amortized to periodic health care
expense over the 13-year average future expected lifetime of retirees and their
surviving spouses beginning in fiscal 1997, the date of the last plan change.

  The accumulated postretirement benefit obligation ("APBO") was determined
using the projected unit credit method and assumed discount rates of 6.5% and 7%
in 1998 and 1997, respectively. In addition, an annual rate increase of 8.5% in
the per capita cost of health care benefits was assumed, gradually declining to
4.5% in the year 2007 and continuing thereafter at that rate over the projected
payout period of the benefits. The health care cost trend rate assumption has a
significant effect on the APBO. For example, a 1% increase in the health care
cost trend rate would increase the APBO at November 30, 1998 by approximately
$3,837 and increase the 1998 expense by approximately $294.

DEFERRED COMPENSATION PLANS:

  The Corporation adopted a deferred compensation plan effective January 1, 1998
for the benefit of executive officers and key employees. The unfunded plan
allows participants to elect to defer salary and bonus subject to certain
limits. An accrued liability for the plan of $2,202 has been accrued at November
30, 1998.

OTHER RETIREMENT PLANS:

  The Corporation also sponsors a number of defined contribution retirement
plans. Participation in these plans is available to substantially all salaried
employees and to certain groups of hourly employees. The Corporation's cash
contributions to these plans are based on either a percentage of employee
contributions or on a specified amount per hour based on the provisions of each
plan. Costs associated with these plans totaled $12,219, 12,354 and $3,192 for
1998, 1997 and 1996, respectively.

  The net cost of all of the above plans was  $31,408 in 1998, $30,846 in 1997
and $9,174 in 1996.

  In January 1998, the Corporation and a brokerage firm owned by a member of the
Board of Directors approved a new agreement for insurance and bond services
supplied to the Corporation effective January 1, 1998 and expiring December 31,
2000, with automatic renewal annually for 12-month terms thereafter, unless
canceled by either party prior to the annual date. Pursuant to the agreement,
the brokerage firm receives an annual fixed fee of $1,150, which will be paid in
equal quarterly installments with all insurance commissions earned to be
credited 100% against the fee.

  Negotiations of the proposed acquisition of an interest in a copper mine
between the Corporation and a principal stockholder and the Chairman of the
Board of Directors were terminated in January, 1998.

13.  CONTINGENCIES AND COMMITMENTS

SUMMITVILLE ENVIRONMENTAL MATTERS:

  From July 1985 to June 1989, a subsidiary of the Corporation performed certain
contract mining services at the Summitville mine near Del Norte, Colorado. The
United States Environmental Protection Agency (the "EPA") has notified the
Corporation and approximately 20 other parties that each is a potentially
responsible party ("PRP") with regard to hazardous substances generated or
disposed of at the Summitville Mine Superfund Site (the "Site"). The EPA has not
commenced any litigation or other proceedings against the Corporation. The
Corporation has had only preliminary discussions with the EPA but has been
informally advised that the EPA does not consider the Corporation eligible for a
de minimis settlement (the basis for settlement by several PRPs considered to
have contributed less than 3% volume and toxicity of the hazardous substances at
the Site).

  According to a report published in August 1996, the EPA estimated that the
total remediation costs incurred and to be incurred at the Site will be
$120,000. The Corporation is not a party to any agreement regarding an
allocation of responsibility, and the EPA has not made an allocation of
responsibility among the PRPs. The Corporation's share, if any, of the aggregate
environmental liability associated with the Site is not presently determinable
and depends upon, among other things, the manner in which liability may be
allocated to or among the Corporation or other PRPs associated with the Site,
the efficacy of any defenses that the Corporation or such other PRPs may have to
any assertion of liability, the willingness and ability of such other PRPs to
discharge such liability as may be allocated to them and the outcome of any
negotiations or settlement discussions between the Corporation and the EPA
and/or such other PRPs. Accordingly, no remediation costs have been accrued at
November 30, 1998.

  Management believes that the ultimate resolution of this matter could have a
material adverse effect on the Corporation's financial position and could
materially and adversely effect its results of operations and cash flows in one
or more periods.

OTHER ENVIRONMENTAL MATTERS:

  The Corporation has been identified as a PRP and is contingently liable for
remediation liabilities in connection with Old MK's former Transit business. The
Corporation agreed to indemnify the buyer of the Transit business for
remediation costs and has therefore accrued $3,000. While the Corporation's
range of loss cannot be estimated, management believes that the ultimate outcome
of the matter will not have a material adverse effect on the Corporation's
financial position, results of operations or cash flows.

                                     II-32
<PAGE>
 
  The Corporation has assumed an undiscounted liability of Old MK which at
November 30, 1998 was $1,753 for environmental cleanup activities at four other
sites. The Corporation estimates that such costs could range from $1,000 to
$1,800 in the aggregate.

CONTRACT RELATED MATTERS:

  In 1995, Old MK entered into a fixed-price contract with the Texas Natural
Resource Conservation Commission ("TNRCC") for construction of a solvent-
extraction facility and treatment of contaminated soil at a Superfund site in
Texas. The TNRCC notified the Corporation in February 1998 that it was
terminating its contract with the Corporation. In the fourth quarter of 1998,
the Corporation received $1,600 as settlement for all issues relating to this
contract, and the TNRCC has released the Corporation's letter of credit in the
amount of $13,619 that had been provided by the Corporation to collateralize its
obligations under the contract.

  In the fourth quarter of 1997, the Corporation assumed sponsorship of a large,
fixed-price joint-venture contract due to the bankruptcy of the previous sponsor
and recorded a $3,900 pretax loss due to uncertainties on the project, including
unpaid client-directed change orders and potential project claims. Management
believes that acceptable pricing will be achieved by further negotiation with
the client. The ultimate outcome cannot be currently determined with certainty
and may not occur in the near term.

  The Corporation has a number of cost reimbursable contracts with the U.S.
government, the allowable costs of which are subject to adjustments upon audit
and negotiation by various agencies of the U.S. government. Audits and
negotiations of the Corporation's allocation of periodic costs of insurance
programs are complete through 1997, resulting in a $4,300 credit refund by the
Corporation to certain U.S. government contracts to be applied over two years.
Audits and negotiations of indirect costs are substantially complete through
1996. The anticipated adjustment in favor of the government is $1,000 for which
the Corporation has previously established a reserve. Audits of 1997 indirect
costs are in progress.

LETTERS OF CREDIT:

  In the normal course of business, the Corporation causes letters of credit to
be issued in connection with contract performance obligations which are not
reflected in the balance sheet. The Corporation is obligated to reimburse the
issuer of such letters of credit for any payments made thereunder. At November
30, 1998 and 1997, $37,157 and $41,297, respectively, in face amount of such
letters of credit were outstanding. The Corporation has pledged securities
available for sale as collateral for its reimbursement obligations in respect of
$3,443 in face amount of certain letters of credit that were outstanding at
November 30, 1998.

  In connection with a 1989 sale of Old MK's ownership interest of a
shipbuilding subsidiary, the Corporation assumed a guarantee of port facility
bonds of $21,000 through 2002. The former subsidiary has collateralized the
bonds with certain assets and has established a sinking fund of $5,272 for the
bonds. No loss on the guarantee is probable and, accordingly, no accrual has
been made by the Corporation.

LONG-TERM LEASES:

  Total rental payments for real estate and equipment under lease charged to
operations in 1998, 1997, and 1996 were $52,067, $36,575 and $11,780,
respectively. Future minimum rental payments under operating leases, some of
which contain renewal or escalation clauses, with remaining noncancelable terms
in excess of one year at November 30, 1998 were as follows:

OTHER:

  In May 1998, Leucadia National Corporation filed an action against the
Corporation and certain officers and directors in The United States District
Court for the District of Utah, Civil Action Number 2:98CV-0327S. The complaint
alleges fraud in the sale of shares of MK Gold Corporation by Old MK to Leucadia
and seeks rescission of the sale and restitution of $22,500. Leucadia contends
that the Corporation knew or believed that a non-competition agreement between
the Corporation and MK Gold was unenforceable and failed to disclose that belief
to Leucadia. The non-competition agreement is the subject of separate litigation
between MK Gold and the Corporation. On January 5, 1999, the two cases were
consolidated for trial. No trial date has been set.

  The Corporation and certain current and former officers, employees and
directors were named defendants in two legal actions: John B. Blyler and Malcolm
J. Corse v. William J. Agee, et. al., Civil Action No. 97-0332-S-BLW ("Blyler
case") and Martin Radwell v. Dennis R. Washington, et. al., Civil Action No.
15934 ("Radwell case"). The complaint in the Blyler case alleges, among other
things, that the defendants breached certain fiduciary duties. The Radwell case
was dismissed in 1998 following stockholder approval of a settlement between the
parties. The settlement amount was not material.

  Although the ultimate outcome of these matters cannot be predicted with
certainty, management believes that the outcome of these actions, individually
or collectively, will not have a material adverse impact on the Corporation's
financial position, results of operations or cash flows.

  In addition to the foregoing, there are other claims, lawsuits, disputes with
third parties, investigations and administrative proceedings against the
Corporation and its subsidiaries relating to matters in the ordinary course of
its business activities that are not expected to have a material adverse effect
on the Corporation's financial position, results of operations or cash flows.

14.  ACQUISITION OF WESTINGHOUSE BUSINESSES

  On June 26, 1998, the Corporation announced the formation of a joint venture
with British Nuclear Fuels, Ltd. ("BNFL") to acquire  certain businesses (the
"Westinghouse businesses") from CBS Corporation (formerly known as Westinghouse
Electric Corporation). The transaction is subject to regulatory approvals and is
expected to close in  the second quarter of 1999. The Westinghouse businesses,
which consist of the Government and Environment Services Company ("GESCO") and
the Energy Systems Business Unit ("ESBU"), and which are both divisions of CBS
Corporation, provide a wide range of products, services and technologies in the
government services and nuclear industries throughout the world.

  GESCO manages highly complex facilities and programs for the United States
Departments of Energy and Defense. GESCO also provides a wide range of services
at government installations, including the production of tritium for national
weapons programs and high-level waste solidification. GESCO employs over 13,000
employees, including those at government-owned, contractor-operated locations.

  ESBU provides commercial nuclear power technology with emphasis on service,
fuel and instrumentation and control technologies for the world's operating
nuclear power plants. ESBU is also heavily involved in the development of new
plant technology and has received final design approval from the Nuclear
Regulatory Commission for its advanced nuclear power plant, the AP600. ESBU has
approximately 4,000 employees.

   The Corporation was informed by CBS that the Department of the Navy has
chosen another party to perform certain contracts which were to be part of the
acquisition of the Westinghouse businesses and that CBS Corporation had formally
protested the award of those Navy contracts. This protest was unsuccessful. The
purchase price for the acquisition of the Westinghouse businesses has,
therefore, been adjusted downward by $38,000 to approximately $1,150,000
(consisting of $200,000 in cash and the assumption of approximately $950,000 in
specified liabilities, commitments and obligations). Under the  transaction
structure currently proposed, the Corporation's share of the purchase price
would be approximately $120,000 in cash.

  During the second half of 1998, the Corporation and BNFL entered into
negotiations with GESCO's primary client, the Department of Energy, regarding
the transfer of GESCO and ESBU and the contracts that each of those units has
with the Departments of Energy and Defense. As a result of those negotiations,
the Corporation and BNFL have proposed a transaction structure pursuant to which
(1) the Corporation and BNFL would form three limited liability companies -
Westinghouse Government Services Company, L.L.C. ("WGS"), which would acquire
the portion of GESCO's business relating to defense program services -
Westinghouse Government Environmental Services Company, L.L.C. ("WGES"), which
would acquire the portion of GESCO's business relating to environmental
remediation and waste management services - and Westinghouse Electric Company,
L.L.C. ("WEC"), which would acquire ESBU, (2) the Corporation would hold 100% of
the membership interests in WGS and 60% of the membership interests in WGES and
BNFL would hold 100% of the membership interests in WEC and 40% of the
membership interests in WGES, and (3) the Corporation would assign a passive
economic right to 40% of profits and losses of WGS to BNFL. These arrangements
are subject to final Department of Energy approval and approval by the Committee
on Foreign Investment in the United States.

  The Corporation intends to fund its share of the purchase price and the
working capital requirements of the Westinghouse businesses using existing
financing facilities, additional financing facilities for which the Corporation
has received commitments or an offering of senior unsecured notes, together with
cash on hand and cash from other operations. The terms of such additional
borrowings have not yet been finalized.

17.  CAPITAL STOCK, STOCK PURCHASE WARRANTS AND STOCK COMPENSATION PLAN

CAPITAL STOCK:

  Pursuant to its Certificate of Incorporation, the Corporation has the
authority to issue 100,000,000 shares of common stock and 10,000,000 shares of
preferred stock. Preferred stock may be issued at any time or from time to time
in one or more series with such designations, powers, preferences and rights,
qualifications, limitations or restrictions thereof as determined by the Board
of Directors of the Corporation.

STOCK PURCHASE WARRANTS:

  At November 30, 1998, the Corporation had outstanding stock purchase warrants
giving rights to acquire 2,945,582 shares of the Corporation's common stock at
an exercise price of $12.00 per share. Of such warrants 2,757,734 expire in
March 2003, and 187,848 expire in September 2001.

STOCK REPURCHASE PROGRAM:

  In January 1998, the Board of Directors authorized the purchase, from time to
time, of up to 2 million shares of the Corporation's common stock to counteract
the dilutive effect of the issuance of stock under its stock option plans and up
to 2.765 million of its stock purchase warrants. As of November 30, 1998,
973,100 shares have been repurchased at a cost of $12,848.

                                     II-36
<PAGE>
 
STOCK COMPENSATION PLAN:

  The Corporation has a stock compensation plan for employees and non-employee
directors  (the "1994 plan") which provides for grants in the form of
nonqualified stock options or incentive stock options ("ISOs") and restricted
stock awards. Additional shares of common stock available each year for grants
under the 1994 plan are equal to 3% of the outstanding shares as of  the first
day of such year.  Exercise prices for nonqualified stock options are determined
by the Board of Directors. Exercise prices for ISOs are equal to the fair market
value of the Corporation's common stock at the date of grant. Stock options
extend for and vest over periods of up to ten years as determined by the Board.
The Board may accelerate the vesting period after award of an option. The number
of shares available for grant of ISOs may not exceed 2,900,000 shares, and no
individual shall be granted stock options or restricted stock awards for more
than 5,000,000 shares over any three-year period.

  Non-employee directors may elect to forego receipt in cash of certain fees
earned during any year in return for an option with a grant price equal to 80%
of the fair market value of the Corporation's common stock,  vesting quarterly
during the year with a term period of up to ten years as determined by the
Board. Non-employee directors elected options for 88,204,  95,556 and 50,461
shares in lieu of fees earned in 1998, 1997 and 1996, respectively.

  On April 11, 1997, the Corporation's stockholders adopted the 1997 Stock
Option and Incentive Plan for Non-employee Directors (the "1997 plan") which
provides for grants in the form of nonqualified stock options and restricted
stock awards. Grant prices per share for stock options are at fair market value
at the date of grant. The number of shares available for grant as options and
restricted stock awards is 500,000, of which no more than 100,000 may be awarded
as restricted. Grants of nonqualified stock options and restricted stock awards
to the non-employee directors under the 1997 plan do not preclude grants under
the 1994 plan. Options are subject to terms and conditions determined by the
Board of Directors and have a term not exceeding 10 years from the date of
grant. Option activity under the Corporation's stock plans is summarized as
follows:

  The terms and conditions of restricted stock awards issued to key employees
are determined by the Board. Upon termination of employment, shares that remain
subject to restriction are forfeited. At November 30, 1998, there were no
restricted shares outstanding. No restricted stock awards were made in 1998,
1997 and 1996.

STOCK-BASED COMPENSATION:

  The Corporation has adopted the disclosure-only provisions of the Financial
Accounting Standards Board Statement No. 123 Accounting for Stock-Based
Compensation ("SFAS No. 123") issued in October 1995. Accordingly, compensation
cost has been recorded based on the intrinsic value of the option only. The
Corporation recognized $219, $477 and $702 of compensation cost in 1998, 1997
and 1996, respectively, for stock-based employee compensation awards. If the
Corporation had elected to recognize compensation cost based on the fair value
of the options granted at grant date as prescribed by SFAS No. 123, net income
and earnings per share would have been reduced to the pro forma amounts as
follows:
<TABLE>
<CAPTION>

 Pro forma - basic and diluted        .67      .57     (.13)
-------------------------------------------------------------------
</TABLE>

  The pro forma amounts set forth above reflect the portion of the estimated
fair value of awards earned in 1998, 1997 and 1996 based on the vesting period
of the options. The pro forma effects disclosed above are not likely to be
representative of the pro forma disclosures of future years because SFAS No. 123
is applicable only to options granted subsequent to November 30, 1995, the
effect of which will not be fully reflected until 1999.

  The Black-Scholes option valuation model was used to estimate the fair value
of the options for purposes of the pro forma presentation set forth above.

  The following assumptions were used in the valuation and no dividends were
assumed:
<TABLE>

--------------------------------------------------------------------------

Weighted-average fair value:
 Exercise price equal to market price at grant     $9.47   $10.23   $7.98
 Exercise price less than market price at grant    $7.80   $ 7.20       -
--------------------------------------------------------------------------
</TABLE>

  The assumptions used in the Black-Scholes option valuation model are highly
subjective, particularly as to stock price volatility of the underlying stock,
and can materially affect the resulting valuation. In management's opinion, the
model does not provide a reliable single measure of the fair value of the
employee stock options.

18.  FINANCIAL INSTRUMENTS

  The estimated fair values of financial instruments at November 30, 1998 have
been determined by the Corporation, using available market information and
valuation methodologies believed to be appropriate. However, judgment is
necessary in interpreting market data to develop the estimates of fair values.
Accordingly, the estimates presented herein are not necessarily indicative of
the amounts that the Corporation could realize in a current market exchange. The
use of different market assumptions and/or estimation methodologies may have a
material effect on the estimated fair value amounts.

  The carrying amounts and estimated fair values of certain financial
instruments at November 30, 1998 and 1997 were as follows:

securities available for sale based on quoted market prices of the securities at
the balance sheet date, and (iii) customer retentions, subcontract retentions
and customer advances estimated by discounting expected cash flows at rates
currently available to the Corporation for instruments with similar risks and
maturities.
