CONTRACTUAL OBLIGATIONS The following table summarizes our significant contractual obligations as of December 31, 2017:
## Table 0 ##
(1) Includes principal, as well as estimated interest payments.
For our variable-rate debt, we have assumed a constant 30-day LIBOR rate of 1.55 percent as of December 31, 2017.
The total amount of unrecognized tax benefits as of December 31, 2017 was $283 million.
This amount is excluded from the table above because these unrecognized tax benefits are uncertain and subject to the findings of the taxing authorities in the jurisdictions where we are subject to tax.
It is possible that the amount of the liability for unrecognized tax benefits could change during the next year.
Refer to Note 14: “Income Taxes” in our consolidated financial statements for additional information on our liability for unrecognized tax benefits.
In addition to the purchase commitments in the table above, in the normal course of business we enter into purchase commitments for which we are reimbursed by the owners of our managed and franchised hotels.
These obligations have minimal or no effect on our net income (loss) and cash flows.
OFF-BALANCE SHEET ARRANGEMENTS Our off-balance sheet arrangements as of December 31, 2017 included letters of credit of $41 million and performance guarantees with possible cash outlays of approximately $79 million, for which we accrued $21 million as of December 31, 2017 for estimated probable exposure.
See Note 20: “Commitments and Contingencies” in our consolidated financial statements for additional information.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES The preparation of our consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated financial statements, the reported amounts of revenues and expenses during the reporting periods and the related disclosures in the consolidated financial statements and accompanying footnotes.
We believe that of our significant accounting policies, which are described in Note 2: “Basis of Presentation and Summary of Significant Accounting Policies” in our consolidated financial statements, the following accounting policies are critical because they involve a higher degree of judgment, and the estimates required to be made were based on assumptions that are inherently uncertain.
As a result, these accounting policies could materially affect our financial position, results of operations, cash flows and related disclosures.
On an ongoing basis, we evaluate these estimates and judgments based on historical experiences and various other factors that are believed to reflect the current circumstances.
While we believe our estimates, assumptions and judgments are reasonable, they are based on information presently available.
Actual results may differ significantly from these estimates due to changes in judgments, assumptions and conditions as a result of unforeseen events or otherwise, which could have a material effect on our financial position or results of operations.
Management has discussed the development and selection of the following critical accounting policies and estimates with the audit committee of the board of directors.
GOODWILL We evaluate goodwill for potential impairment annually and at an interim date if indicators of impairment exist.
When using the quantitative process to evaluate goodwill for potential impairment, consistent with our early adoption of ASU No.2017-04 in January 2017, we compare the estimated fair value of the reporting unit to the carrying value.
When determining the estimated fair value, we utilize discounted future cash flow models, as well as market conditions relative to the operations of our reporting units.
Under the discounted cash flow approach, we utilize various assumptions that require judgment, including projections of revenues and expenses based on estimated long-term growth rates, and discount rates based on weighted average cost of capital.
Our estimates of long-term growth and costs are based on historical data, as well as various internal projections and external sources.
The weighted average cost of capital is estimated based on each reporting units’ cost of debt and equity and a selected capital structure.
The selected capital structure for each reporting unit is based on consideration of capital structures of comparable publicly traded companies operating in the business of that reporting unit.
We had $5,190 million of goodwill as of December 31, 2017.
Changes in the estimates and assumptions used in our goodwill impairment testing could result in future impairment losses, which could be material.
Additionally, when a portion of a reporting unit is disposed, goodwill is allocated to the gain or loss on disposition based on the relative fair values of the business or businesses disposed and the portion of the reporting unit that will be retained.
When determining fair value of the businesses disposed of and the reporting unit to be retained, we use estimates and assumptions similar to those used in our impairment analysis.

During each of the three years ended December 31, 2010, 2009 and 2008, no single customer exceeded 10% of consolidated revenue.
Schlumberger did not have revenue from third-party customers in its country of domicile during the last three years.
Revenue in the United States in 2010, 2009 and 2008 was $6.5 billion, $3.7 billion and $5.9 billion, respectively.18.
Pension and Other Benefit Plans Pension Plans Schlumberger sponsors several defined benefit pension plans that cover substantially all US employees hired prior to October 1, 2004.
The benefits are based on years of service and compensation, on a career-average pay basis.
In addition to the United States defined benefit pension plans, Schlumberger sponsors several other international defined benefit pension plans.
The most significant of these international plans are the International Staff Pension Plan, which was converted from a defined contribution plan to a defined benefit pension plan during the fourth quarter of 2008, and the UK pension plan (collectively, the “International plans”).
The International Staff Pension Plan covers certain international employees and is based on years of service and compensation on a career-average pay basis.
The UK plan covers employees hired prior to April 1, 1999, and is based on years of service and compensation, on a final salary basis.
PART I Item 1: Business Incorporated in 1967, Applied, a Delaware corporation, provides manufacturing equipment, services and software to the global semiconductor, flat panel display, solar photovoltaic (PV) and related industries.
Applied’s customers include manufacturers of semiconductor wafers and chips, flat panel liquid crystal and other displays, solar PV cells and modules, and other electronic devices.
These customers may use what they manufacture in their own end products or sell the items to other companies for use in advanced electronic components.
Applied’s fiscal year ends on the last Sunday in October.
Applied operates in four reportable segments: Silicon Systems Group, Applied Global Services, Display, and Energy and Environmental Solutions.
Applied manages its business based upon these segments.
A summary of financial information for each reportable segment is found in Note 16 of Notes to Consolidated Financial Statements.
A discussion of factors that could affect operations is set forth under “Risk Factors” in Item 1A, which is incorporated herein by reference.
In November 2011, Applied completed the acquisition of Varian Semiconductor Equipment Associates, Inc.  (Varian), a leading supplier of ion implantation equipment to the semiconductor and solar industries.
The acquisition expanded Applied's technologies for chip and solar module manufacturing.
The acquired business is primarily included in consolidated results of operations and the results of the Silicon Systems Group and Applied Global Services segments.
Net sales by reportable segment for the past three fiscal years were as follows:
## Table 3 ##
Silicon Systems Group Segment The Silicon Systems Group segment develops, manufactures and sells manufacturing equipment used to fabricate semiconductor chips, also referred to as integrated circuits (ICs).
Most chips are built on a silicon wafer base and include a variety of circuit components, such as transistors and other devices, that are connected by multiple layers of wiring (interconnects).
Applied offers systems that perform various processes used in chip fabrication, including atomic layer deposition (ALD), chemical vapor deposition (CVD), physical vapor deposition (PVD), electrochemical deposition (ECD), rapid thermal processing (RTP), ion implantation, chemical mechanical planarization (CMP), wet cleaning, and wafer metrology and inspection, as well as systems that etch or inspect circuit patterns on masks used in the photolithography process.
Applied’s semiconductor manufacturing systems are used by integrated device manufacturers and foundries to build and package memory, logic and other types of chips.
The majority of the Company's new equipment sales are for leading-edge technology for advanced nodes using 28 nanometer (nm) and smaller dimensions.
To build a chip, the transistors, capacitors and other circuit components are first created on the surface of the wafer by performing a series of processes to deposit and selectively remove portions of successive film layers.
Similar processes are then used to build the layers of wiring structures on the wafer.
As the density of the circuit components increases to enable greater computing capability in the same or smaller physical area, the complexity of building the chip also increases, necessitating more process steps to form smaller transistor structures and more intricate wiring schemes.
Advanced chip designs require more than 500 steps involving these and other processes to complete the manufacturing cycle.
Today's advanced interconnects are made using copper as the main wiring material.
Copper has low resistance and can carry a large amount of current in a small area, which allows signals to travel quickly.
Applied is a leading supplier of systems for manufacturing copper-based interconnects, including equipment for depositing, etching and planarizing these multi-layer structures.
APPLIED MATERIALS, INC.  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) 100 The following table summarizes information with respect to options outstanding and exercisable at October 27, 2013:
## Table 4 ##
Option prices at the lower end of the range were principally attributable to stock options assumed in connection with the Varian acquisition in fiscal year 2012.
Restricted Stock Units, Restricted Stock, Performance Shares and Performance Units Restricted stock units are converted into shares of Applied common stock upon vesting on a one-for-one basis.
Restricted stock has the same rights as other issued and outstanding shares of Applied common stock except these shares generally have no right to dividends and are held in escrow until the award vests.
Performance shares and performance units are awards that result in a payment to a grantee in shares of Applied common stock on a one-for-one basis if performance goals and/or other vesting criteria established by the Human Resources and Compensation Committee of Applied's Board of Directors (the Committee) are achieved or the awards otherwise vest.
Restricted stock units, restricted stock, performance shares and performance units typically vest over four years and vesting is usually subject to the grantee’s continued service with Applied and, in some cases, achievement of specified performance goals.
The compensation expense related to the service-based awards is determined using the fair market value of Applied common stock on the date of the grant, and the compensation expense is recognized over the vesting period.
Restricted stock, performance shares and performance units granted to certain executive officers are also subject to the achievement of specified performance goals (performance-based awards).
These performance-based awards become eligible to vest only if performance goals are achieved and then actually will vest only if the grantee remains employed by Applied through each applicable vesting date.
These performance-based awards require the achievement of targeted levels of relative adjusted annual operating profit margin.
For the fiscal 2013 and fiscal 2012 performance-based awards, additional shares become eligible for time-based vesting if Applied achieves certain levels of total shareholder return (TSR) relative to a peer group comprised of companies in the Standard & Poor's 500 Information Technology Index measured at the end of a two-year period.
In September 2013, the Committee approved the amendment of certain outstanding performance-based awards, so that applicable performance goals will be deemed satisfied at target levels effective as of either three days prior to the closing of the announced business combination between Applied and TEL, or the date the proposed business combination is terminated.
The vesting of the awards will remain subject to time-based vesting.
In addition, the Committee also approved the amendment of certain outstanding awards held by executive officers to provide that if the award is outstanding and subject solely to time-based vesting as of three trading days prior to the closing of the business combination agreement with TEL, vesting of the portion of the award that is otherwise scheduled to vest during calendar year 2014 will accelerate.
The fair value of these performance-based awards is estimated on the date of grant and assumes that the specified performance goals will be achieved.
If the goals are achieved, these awards vest over a specified remaining service period of generally three or four years, provided that the grantee remains employed by Applied through each scheduled vesting date.
If the performance goals are not met, no compensation expense is recognized and any previously recognized compensation expense is reversed.
The expected cost of each award is reflected over the service period and is reduced for estimated forfeitures.
Performance Graph The performance graph below shows the five-year cumulative total stockholder return on Applied common stock during the period from October 26, 2008 through October 27, 2013.
This is compared with the cumulative total return of the Standard & Poor’s 500 Stock Index and the RDG Semiconductor Composite Index over the same period.
The comparison assumes $100 was invested on October 26, 2008 in Applied common stock and in each of the foregoing indices and assumes reinvestment of dividends, if any.
Dollar amounts in the graph are rounded to the nearest whole dollar.
The performance shown in the graph represents past performance and should not be considered an indication of future performance.

Dividends During fiscal 2013, Applied’s Board of Directors declared three quarterly cash dividends of $0.10 per share each and one quarterly cash dividend of $0.09 per share.
During fiscal 2012, Applied’s Board of Directors declared three quarterly cash dividends of $0.09 per share each and one quarterly cash dividend of $0.08 per share.
During fiscal 2011, Applied’s Board of Directors declared three quarterly cash dividends of $0.08 per share each and one quarterly cash dividend of $0.07.
Dividends declared during fiscal 2013, 2012 and 2011 totaled $469 million, $438 million and $408 million, respectively.
Applied currently anticipates that it will continue to pay cash dividends on a quarterly basis in the future, although the declaration and amount of any future cash dividends are at the discretion of the Board of Directors and will depend on Applied’s financial condition, results of operations, capital requirements, business conditions and other factors, as well as a determination that cash dividends are in the best interests of Applied’s stockholders.
Fiscal 2012 financial results reflected continued uncertain global economic conditions that led to decreased demand for semiconductor manufacturing equipment compared to fiscal 2011, particularly in the second half of fiscal 2012.
In the fourth quarter of fiscal 2012, new orders were $741 million, a decrease of 36 percent compared to the third quarter of fiscal 2012.
The decrease in new orders in fiscal 2012 from the prior year was primarily due to reduced demand from memory and logic customers, partially offset by the addition of Varian.
Net sales increased slightly in fiscal 2012 from the prior year due to the addition of net sales attributable to Varian, partially offset by decreased investment from memory and logic customers.
Three customers accounted for 60 percent of net sales in this segment in fiscal 2012.
Approximately 53 percent of net sales in the fourth quarter of fiscal 2012 were for orders received and shipped within the quarter, which remained flat from the third quarter of fiscal 2012.
Operating income and non-GAAPadjusted operating income for fiscal 2012 decreased compared to fiscal 2011, due to changes in customer and product mix with the inclusion of Varian, costs associated with Varian operations, and additional inventory charges.
Operating income for fiscal 2012 also included Varian acquisition-related costs of $290 million.
Applied Global Services Segment The Applied Global Services segment encompasses spares, upgrades, services, remanufactured earlier generation equipment and factory automation software for semiconductor, display and solar manufacturing.
These products are designed to improve customers' operating efficiency, optimize their operating costs, and lessen the environmental impact of their factories.
Customer demand for products and services is fulfilled through a global distribution system with trained service engineers located in close proximity to customer sites.
Certain significant measures for the past three fiscal years were as follows:
## Table 6 ##
Reconciliations of non-GAAP adjusted measures are presented under "Non-GAAP Adjusted Results" below.
There were no individual regions that accounted for at least 30 percent of total net sales for the Applied Global Services segment for any of the past three fiscal years.
For fiscal 2013, new orders and net sales decreased compared to fiscal 2012 due primarily to lower demand and investments for semiconductor spares and services.
In addition, the decrease in net sales was also due to lower investments in display upgrades.
Fiscal 2012 net sales also included $85 million in sales for a thin film solar production line.
Operating income and non-GAAP adjusted operating income decreased in fiscal 2013 compared to fiscal 2012, reflecting lower sales and a $20 million customs duty assessment, partially offset by lower operating expenses from spending controls.
