SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	9 Months Ended
	Sep. 30, 2017
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Principles of Consolidation The condensed consolidated financial statements have been prepared in accordance with accounting principles for interim financial information and with the instructions to Form 10-Q S-X. These condensed consolidated financial statements present the financial position, results of comprehensive income and cash flows of the Company. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Form 10-K Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and the reported amounts of revenue and expenses. Estimates include, but are not limited to, sales allowances, government price adjustments, fair market values and future cash flows associated with goodwill, indefinite life intangibles, long-lived asset impairment tests, useful lives for depreciation and amortization, warranty liabilities, environmental liabilities, determination of discount and other assumptions for pension and other postretirement benefit expense, income taxes and deferred tax valuation allowances, derivative valuation, and contingencies. The Company’s accounting policies involve the application of judgments and assumptions made by management that include inherent risks and uncertainties. Actual results could differ materially from these estimates. Changes in estimates are recorded in results of operations in the period that the events or circumstances giving rise to such changes occur. Impairment of Assets During the fourth quarter of every year, the Company performs additional reviews of its goodwill, other intangible assets and long-lived assets to determine whether the carrying value of an asset may not be recoverable. The Company has recorded impairments to both its Trade name and long-lived assets in prior periods with the most recent impairments recorded in 2015. The Company performs its annual goodwill and intangible assets impairment analysis on October 31 of every year. Events or circumstances that could unfavorably impact the key assumptions in the impairment test include lower net sales, the Company’s inability to execute on marketing programs and/or delay in the introduction of new products, lower gross margins or failure to obtain forecasted cost reductions, or a higher discount rate as a result of market conditions. The carrying value of long-lived assets is evaluated when events or circumstances indicate that there has been a significant change in the use of an asset, or the planned sale or disposal of an asset. The asset would be considered impaired when there is no future use planned for the asset or the future net undiscounted cash flows generated by the asset or asset group are less than its carrying value. An impairment loss would be recognized based on the amount by which the carrying value exceeds fair value. Assumptions and estimates used to determine cash flows in the evaluation of impairment and the fair values used to determine the impairment are subject to a degree of judgment and complexity. Any changes to the assumptions and estimates resulting from changes in actual results or market conditions from those anticipated may affect the carrying value of long-lived assets and could result in an impairment charge. Recently Adopted Accounting Pronouncements In January 2017, the Financial Accounting Standards Board (“FASB”) issued authoritative accounting guidance on evaluation of goodwill for impairment. The guidance modifies the approach to assessing impairment from testing the implied fair value goodwill to testing the fair value of the reporting unit carrying the goodwill, which eliminates Step 2 of the current evaluation guidance. The intent of this amendment is to reduce the cost and complexity of evaluating goodwill. The guidance was early adopted by the Company effective July 1, 2017. The adoption of this guidance did not have an impact on the Company’s consolidated financial statements. In March 2016, the FASB issued authoritative accounting guidance on share-based payment awards to employees. The guidance involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance was adopted by the Company effective January 1, 2017. Management recorded an excess tax benefit of $5 million and $16 million to income tax expense and as a component of operating cash flows for the three months and nine months ended September 30, 2017, respectively, and made the accounting policy election to account for forfeitures as they occur. In July 2015, the FASB issued authoritative accounting guidance to simplify the measurement of inventory. The guidance requires that inventory be measured at the lower of cost and net realizable value. When evidence exists that the net realizable value of inventory is lower than its cost, the difference shall be recognized as a loss in earnings in the period in which it occurs. Inventory measured using last-in, first-out Recently Issued Accounting Pronouncements In May 2017, the FASB issued authoritative accounting guidance on accounting for modifications to the terms of employee stock compensation. The guidance clarifies which changes to terms or conditions of share-based payment awards require the entity to apply modification accounting. The guidance will be effective for the Company in fiscal year 2018, but early adoption is permitted. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. In March 2017, the FASB issued authoritative accounting guidance on the presentation of net periodic pension costs and net periodic postretirement benefit costs. The guidance clarifies the presentation of component costs within an employer’s financial statements and restricts component costs eligible for capitalization to the service cost component. The Company did not early adopt, therefore the guidance will be effective for the Company in fiscal year 2018. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. In October 2016, the FASB issued authoritative accounting guidance on the income tax consequences of intra-company transfers other than inventory. This guidance addresses the timing of the recognition of current and deferred income taxes. Under this guidance, the recognition of current or deferred income taxes will occur at the time of the transfer of the asset. The Company did not early adopt; therefore, the guidance will be effective for the Company in fiscal year 2018. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. In August 2016, the FASB issued authoritative accounting guidance on the presentation and classification of certain cash receipts and cash payments on the statement of cash flows. The guidance specifically addresses cash flow issues with the objective of reducing the diversity in practice. The Company did not early adopt; therefore, the guidance will be effective for the Company in fiscal year 2018. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. In February 2016, the FASB issued authoritative accounting guidance on lease accounting. The guidance requires lessees to present right-of-use In January 2016, the FASB issued authoritative accounting guidance on the classification of equity securities with readily determinable fair values into different categories (e.g. trading or available-for-sale) available-for-sale In May 2014, the FASB issued authoritative accounting guidance on a company’s accounting for revenue from contracts with customers, which guidance has subsequently been amended. The guidance applies to all companies that enter into contracts with customers to transfer goods, services or nonfinancial assets. The guidance requires these companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also requires disclosures regarding the nature, timing, amount and uncertainty of revenue that is recognized. The guidance allows either full or modified retrospective adoption. The Company did not early adopt; therefore, the guidance will be effective for the Company for the annual and interim periods beginning in fiscal year 2018. The Company will implement the guidance using the modified retrospective approach. Management has determined that the revenue streams that will be impacted by the guidance relate to non-standard

FAIR VALUE OF FINANCIAL INSTRUM

FAIR VALUE OF FINANCIAL INSTRUMENTS	9 Months Ended

FAIR VALUE OF FINANCIAL INSTRUMENTS	NOTE E. FAIR VALUE OF FINANCIAL INSTRUMENTS In accordance with the FASB’s authoritative accounting guidance on fair value measurements, fair value is the price (exit price) that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated, or generally unobservable. The Company primarily applies the market approach for recurring fair value measurements and utilizes the best available information that maximizes the use of observable inputs and minimizes the use of unobservable inputs. The Company is able to classify fair value balances based on the observability of those inputs. The accounting guidance establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy defined by the relevant guidance are as follows: Level 1 — Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 primarily consists of financial instruments such as exchange-traded derivatives, listed equities and publicly traded bonds. Level 2 — Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reported date. Level 2 includes financial instruments that are valued using quoted prices in markets that are not active and those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace. Level 3 — Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value. At each balance sheet date, the Company performs an analysis of all instruments subject to authoritative accounting guidance and includes, in Level 3, all of those whose fair value is based on significant unobservable inputs. As of September 30, 2017 and December 31, 2016, the Company did not have any Level 3 financial assets or liabilities. The Company’s assets and liabilities that are measured at fair value include cash equivalents, available-for-sale available-for-sale The Company’s valuation techniques used to calculate the fair value of cash and cash equivalents, available-for-sale The Company uses valuations from the issuing financial institution for the fair value measurement of interest rate derivatives. The Company corroborates the valuation through the use of third-party valuation services using a standard replacement valuation model.

DEBT	NOTE F. DEBT Long-term debt and maturities are as follows (dollars in millions): September 30, December 31, Long-term debt: Senior Secured Credit Facility Term B-3 $ 1,179 $ 1,188 Senior Notes, fixed 5.0%, due 2024 1,000 1,000 Senior Notes, fixed 4.75%, due 2027 400 — Total long-term debt $ 2,579 $ 2,188 Less: current maturities of long-term debt 12 12 deferred financing costs, net 31 29 Total long-term debt, net $ 2,536 $ 2,147 As of September 30, 2017, the Company had $2,579 million of indebtedness associated with Allison Transmission, Inc.’s (“ATI”), the Company’s wholly-owned subsidiary, 5.0% Senior Notes due September 2024 (“5.0% Senior Notes”), ATI’s 4.75% Senior Notes due October 2027 (“4.75% Senior Notes”) and ATI’s Senior Secured Credit Facility (“Senior Secured Credit Facility”), which consists of the Senior Secured Credit Facility Term B-3 B-3 The fair value of the Company’s long-term debt obligations as of September 30, 2017 was $2,623 million. The fair value is based on quoted Level 2 market prices of the Company’s debt as of September 30, 2017. It is not expected that the Company would be able to repurchase a significant amount of its debt at these levels. The difference between the fair value and carrying value of the long-term debt is driven primarily by trends in the financial markets. Senior Secured Credit Facility In March 2017, ATI entered into an amendment with the term loan lenders under its Senior Secured Credit Facility to lower the applicable margins on the Term B-3 B-3 In September 2017, ATI entered into a joinder agreement with the lenders under its Senior Secured Credit Facility to increase the available commitments under the Revolving Credit Facility from $450 million to $550 million. The joinder agreement was treated as a modification to the Revolving Credit Facility under GAAP. The Senior Secured Credit Facility is collateralized by a lien on substantially all assets of the Company including all of ATI’s capital stock and all of the capital stock or other equity interest held by the Company, ATI and each of the Company’s existing and future U.S. subsidiary guarantors (subject to certain limitations for equity interests of foreign subsidiaries and other exceptions set forth in the terms of the Senior Secured Credit Facility). Interest on the Term B-3 all-in B-3 B-3 non-ordinary B-3 non-ordinary The Senior Secured Credit Facility also provides a Revolving Credit Facility, net of an allowance for up to $75 million in outstanding letters of credit commitments. Throughout the nine months ended September 30, 2017, the Company made periodic withdrawals and payments on the Revolving Credit Facility as part of its debt management plans. The maximum amount outstanding at any time during the nine months ended September 30, 2017 on the Revolving Credit Facility was $300 million. As of September 30, 2017, the Company had $533 million available under the Revolving Credit Facility, net of $17 million in letters of credit. Revolving credit borrowings bear interest at a variable base rate plus an applicable margin based on the Company’s total leverage ratio. Interest on the Revolving Credit Facility is either (a) 1.75% over the LIBOR or (b) 0.75% over the greater of the prime lending rate in effect on such day and the federal funds effective rate published by the Federal Reserve Bank of New York plus 0.5%, provided that neither is below 1.75%. In addition, there is an annual commitment fee, based on the Company’s total leverage ratio, on the average unused revolving credit borrowings available under the Revolving Credit Facility. Revolving credit borrowings are payable at the option of the Company throughout the term of the Senior Secured Credit Facility with the balance due in September 2021. The Senior Secured Credit Facility requires the Company to maintain a specified maximum total senior secured leverage ratio of 5.50x when revolving loan commitments remain outstanding on the Revolving Credit Facility at the end of a fiscal quarter. As of September 30, 2017, the Company had no revolving loans outstanding; however the Company would have been in compliance with the maximum total senior secured leverage ratio, achieving a 1.19x ratio. Additionally, within the terms of the Senior Secured Credit Facility, a senior secured leverage ratio at or below 4.00x results in the elimination of excess cash flow payments on the Senior Secured Credit Facility for the applicable year. The Senior Secured Credit Facility also provides certain financial incentives based on our total leverage ratio. A total leverage ratio at or below 4.00x results in a 25 basis point reduction to the applicable margin on the Revolving Credit Facility, and a total leverage ratio at or below 3.50x results in a 12.5 basis point reduction to the Revolving Credit Facility commitment fee and an additional 25 basis point reduction to the applicable margin on the Revolving Credit Facility. These reductions would remain in effect as long as the Company achieves a total leverage ratio at or below the related threshold. As of September 30, 2017, the total leverage ratio was 2.90x. In addition, the Senior Secured Credit Facility, among other things, includes customary restrictions (subject to certain exceptions) on the Company’s ability to incur certain indebtedness, grant certain liens, make certain investments, declare or pay certain dividends, or repurchase shares of the Company’s common stock. As of September 30, 2017, the Company is in compliance with all covenants under the Senior Secured Credit Facility. 5.0% Senior Notes The 5.0% Senior Notes are unsecured and are guaranteed by each of ATI’s domestic subsidiaries that is a borrower under or guarantees the Senior Secured Credit Facility and are unconditionally guaranteed, jointly and severally, by any of ATI’s future domestic subsidiaries that are borrowers under or guarantee the Senior Secured Credit Facility. None of ATI’s domestic subsidiaries currently guarantee its obligations under the Senior Secured Credit Facility, and therefore none of ATI’s domestic subsidiaries currently guarantee the 5.0% Senior Notes. The indenture governing the 5.0% Senior Notes contains negative covenants restricting or limiting the Company’s ability to, among other things: incur or guarantee additional indebtedness, incur liens, pay dividends on, redeem or repurchase the Company’s capital stock, make certain investments, permit payment or dividend restrictions on certain of the Company’s subsidiaries, sell assets, engage in certain transactions with affiliates, and consolidate or merge or sell all or substantially all of the Company’s assets. As of September 30, 2017, the Company is in compliance with all covenants under the indenture governing the 5.0% Senior Notes. 4.75% Senior Notes In September 2017, ATI completed an offering of $400 million of 4.75% Senior Notes. The 4.75% Senior Notes were offered in a private placement exempt from registration under the Securities Act of 1933, as amended. The proceeds from the offering were used for general corporate purposes and to pay related transaction fees and expenses. As a result of the offering, the Company recorded approximately $5 million as deferred financing fees in the Condensed Consolidated Balance Sheets. The 4.75% Senior Notes are unsecured and are guaranteed by each of ATI’s domestic subsidiaries that is a borrower under or guarantees the Senior Secured Credit Facility and are unconditionally guaranteed, jointly and severally, by any of ATI’s future domestic subsidiaries that are borrowers under or guarantee the Senior Secured Credit Facility. None of ATI’s domestic subsidiaries currently guarantee its obligations under the Senior Secured Credit Facility, and therefore none of ATI’s domestic subsidiaries currently guarantee the 4.75% Senior Notes. The indenture governing the 4.75% Senior Notes contains negative covenants restricting or limiting the Company’s ability to, among other things: incur or guarantee additional indebtedness, incur liens, pay dividends on, redeem or repurchase the Company’s capital stock, make certain investments, permit payment or dividend restrictions on certain of the Company’s subsidiaries, sell assets, engage in certain transactions with affiliates, and consolidate or merge or sell all or substantially all of the Company’s assets. As of September 30, 2017, the Company is in compliance with all covenants under the indenture governing the 4.75% Senior Notes.

DERIVATIVES

DERIVATIVES	9 Months Ended

DERIVATIVES	NOTE G. DERIVATIVES The Company is exposed to certain financial risk from volatility in interest rates, foreign exchange rates and commodity prices. The risk is managed through the use of financial derivative instruments including interest rate swaps, foreign currency swaps and commodity swaps, when appropriate. The Company’s current derivative instruments are used strictly as an economic hedge and not for speculative purposes. As necessary, the Company adjusts the values of the derivative instruments for counter-party or credit risk. Interest Rate The Company is subject to interest rate risk related to the Senior Secured Credit Facility and enters into interest rate swap contracts that are based on the LIBOR to manage a portion of this exposure.

INCOME TAXES	NOTE L. INCOME TAXES For the three and nine months ended September 30, 2017, the Company recorded total tax expense of $59 million and $154 million, respectively. The effective tax rate for both the three and nine months ended September 30, 2017 was 35%. For the three and nine months ended September 30, 2016, the Company recorded total tax expense of $26 million and $93 million, respectively. The effective tax rate for the three and nine months ended September 30, 2016 was 37% and 38%, respectively. The decrease in effective tax rate for the three and nine months ended September 30, 2017 was principally driven by increased U.S. income tax deductions and discrete activity related to excess tax benefit from stock-based compensation. The need to establish a valuation allowance against the deferred tax assets is assessed periodically based on a more-likely-than-not The Company continues to provide for a valuation allowance on certain of its foreign deferred tax assets. The Company has determined, based on the evaluation of both objective and subjective evidence available, that this valuation allowance is necessary and that it is more likely than not that the deferred tax assets are not fully realizable. In accordance with the FASB’s authoritative guidance on accounting for uncertainty in income taxes, the Company has recorded a liability for unrecognized tax benefits related to a 2010 Research & Development Credit as of September 30, 2017 and December 31, 2016. The accounting guidance prescribes a recognition threshold and measurement attributes for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. All of the Company’s returns will remain subject to examination by the various taxing authorities for the duration of the applicable statute of limitations (generally three years from the later of the date of filing or the due date of the return).

COMMITMENTS AND CONTINGENCIES	NOTE N. COMMITMENTS AND CONTINGENCIES Environmental Matters The Company has an agreement with the Environmental Protection Agency to perform remedial activities at the Company’s Indianapolis, Indiana manufacturing facilities related to historical soil and groundwater contamination. As of September 30, 2017, the Company had a liability recorded in the amount of $13 million. Claims, Disputes, and Litigation The Company is party to various legal actions and administrative proceedings and subject to various claims arising in the ordinary course of business. These proceedings primarily involve commercial claims, product liability claims, personal injury claims and workers’ compensation claims. The Company believes that the ultimate liability, if any, in excess of amounts already provided for in the condensed consolidated financial statements or covered by insurance on the disposition of these matters will not have a material adverse effect on the financial position, results of operations or cash flows of the Company.

EARNINGS PER SHARE

EARNINGS PER SHARE	9 Months Ended
	Sep. 30, 2017
EARNINGS PER SHARE	NOTE O. EARNINGS PER SHARE The Company presents both basic and diluted earnings per share (“EPS”) amounts. Basic EPS is calculated by dividing net income by the weighted average number of common shares outstanding during the reporting period. Diluted EPS is calculated by dividing net income by the weighted average number of common shares and common equivalent shares outstanding during the reporting period that are calculated using the treasury stock method for stock-based awards. The treasury stock method assumes that the Company uses the proceeds from the exercise of awards to repurchase common stock at the average market price during the period. The assumed proceeds under the treasury stock method include the purchase price that the grantee will pay in the future, compensation cost for future service that the Company has not yet recognized and any tax benefits generated when the award generates a tax deduction. If there would be a shortfall, such an amount would be a reduction of the proceeds to the extent of the gains. The diluted weighted-average common shares outstanding exclude the anti-dilutive effect of certain stock options since such options had an exercise price in excess of the monthly average market value of our common stock. For each of the three months and nine months ended September 30, 2017, 0.2 million outstanding stock options were not included in the diluted EPS calculation because they were anti-dilutive. For each of the three months and nine months ended September 30, 2016, 0.6 million outstanding stock options were not included in the diluted EPS calculation because they were anti-dilutive. The following table reconciles the numerators and denominators used to calculate basic EPS and diluted EPS (in millions, except per share data): Three months ended September 30, Nine months ended September 30, 2017 2016 2017 2016 Net income $ 111 $ 45 $ 289 $ 154 Weighted average shares of common stock outstanding 146 167 152 169 Dilutive effect stock-based awards 1 1 1 1 Diluted weighted average shares of common stock outstanding 147 168 153 170 Basic earnings per share attributable to common stockholders $ 0.75 $ 0.27 $ 1.91 $ 0.91 Diluted earnings per share attributable to common stockholders $ 0.75 $ 0.27 $ 1.90 $ 0.91

SUMMARY OF SIGNIFICANT ACCOUN23

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2017
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The condensed consolidated financial statements have been prepared in accordance with accounting principles for interim financial information and with the instructions to Form 10-Q S-X. These condensed consolidated financial statements present the financial position, results of comprehensive income and cash flows of the Company. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Form 10-K
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and the reported amounts of revenue and expenses. Estimates include, but are not limited to, sales allowances, government price adjustments, fair market values and future cash flows associated with goodwill, indefinite life intangibles, long-lived asset impairment tests, useful lives for depreciation and amortization, warranty liabilities, environmental liabilities, determination of discount and other assumptions for pension and other postretirement benefit expense, income taxes and deferred tax valuation allowances, derivative valuation, and contingencies. The Company’s accounting policies involve the application of judgments and assumptions made by management that include inherent risks and uncertainties. Actual results could differ materially from these estimates. Changes in estimates are recorded in results of operations in the period that the events or circumstances giving rise to such changes occur.
Impairment of Assets	Impairment of Assets During the fourth quarter of every year, the Company performs additional reviews of its goodwill, other intangible assets and long-lived assets to determine whether the carrying value of an asset may not be recoverable. The Company has recorded impairments to both its Trade name and long-lived assets in prior periods with the most recent impairments recorded in 2015. The Company performs its annual goodwill and intangible assets impairment analysis on October 31 of every year. Events or circumstances that could unfavorably impact the key assumptions in the impairment test include lower net sales, the Company’s inability to execute on marketing programs and/or delay in the introduction of new products, lower gross margins or failure to obtain forecasted cost reductions, or a higher discount rate as a result of market conditions. The carrying value of long-lived assets is evaluated when events or circumstances indicate that there has been a significant change in the use of an asset, or the planned sale or disposal of an asset. The asset would be considered impaired when there is no future use planned for the asset or the future net undiscounted cash flows generated by the asset or asset group are less than its carrying value. An impairment loss would be recognized based on the amount by which the carrying value exceeds fair value. Assumptions and estimates used to determine cash flows in the evaluation of impairment and the fair values used to determine the impairment are subject to a degree of judgment and complexity. Any changes to the assumptions and estimates resulting from changes in actual results or market conditions from those anticipated may affect the carrying value of long-lived assets and could result in an impairment charge.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In January 2017, the Financial Accounting Standards Board (“FASB”) issued authoritative accounting guidance on evaluation of goodwill for impairment. The guidance modifies the approach to assessing impairment from testing the implied fair value goodwill to testing the fair value of the reporting unit carrying the goodwill, which eliminates Step 2 of the current evaluation guidance. The intent of this amendment is to reduce the cost and complexity of evaluating goodwill. The guidance was early adopted by the Company effective July 1, 2017. The adoption of this guidance did not have an impact on the Company’s consolidated financial statements. In March 2016, the FASB issued authoritative accounting guidance on share-based payment awards to employees. The guidance involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance was adopted by the Company effective January 1, 2017. Management recorded an excess tax benefit of $5 million and $16 million to income tax expense and as a component of operating cash flows for the three months and nine months ended September 30, 2017, respectively, and made the accounting policy election to account for forfeitures as they occur. In July 2015, the FASB issued authoritative accounting guidance to simplify the measurement of inventory. The guidance requires that inventory be measured at the lower of cost and net realizable value. When evidence exists that the net realizable value of inventory is lower than its cost, the difference shall be recognized as a loss in earnings in the period in which it occurs. Inventory measured using last-in, first-out
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2017, the FASB issued authoritative accounting guidance on accounting for modifications to the terms of employee stock compensation. The guidance clarifies which changes to terms or conditions of share-based payment awards require the entity to apply modification accounting. The guidance will be effective for the Company in fiscal year 2018, but early adoption is permitted. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. In March 2017, the FASB issued authoritative accounting guidance on the presentation of net periodic pension costs and net periodic postretirement benefit costs. The guidance clarifies the presentation of component costs within an employer’s financial statements and restricts component costs eligible for capitalization to the service cost component. The Company did not early adopt, therefore the guidance will be effective for the Company in fiscal year 2018. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. In October 2016, the FASB issued authoritative accounting guidance on the income tax consequences of intra-company transfers other than inventory. This guidance addresses the timing of the recognition of current and deferred income taxes. Under this guidance, the recognition of current or deferred income taxes will occur at the time of the transfer of the asset. The Company did not early adopt; therefore, the guidance will be effective for the Company in fiscal year 2018. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. In August 2016, the FASB issued authoritative accounting guidance on the presentation and classification of certain cash receipts and cash payments on the statement of cash flows. The guidance specifically addresses cash flow issues with the objective of reducing the diversity in practice. The Company did not early adopt; therefore, the guidance will be effective for the Company in fiscal year 2018. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. In February 2016, the FASB issued authoritative accounting guidance on lease accounting. The guidance requires lessees to present right-of-use In January 2016, the FASB issued authoritative accounting guidance on the classification of equity securities with readily determinable fair values into different categories (e.g. trading or available-for-sale) available-for-sale In May 2014, the FASB issued authoritative accounting guidance on a company’s accounting for revenue from contracts with customers, which guidance has subsequently been amended. The guidance applies to all companies that enter into contracts with customers to transfer goods, services or nonfinancial assets. The guidance requires these companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also requires disclosures regarding the nature, timing, amount and uncertainty of revenue that is recognized. The guidance allows either full or modified retrospective adoption. The Company did not early adopt; therefore, the guidance will be effective for the Company for the annual and interim periods beginning in fiscal year 2018. The Company will implement the guidance using the modified retrospective approach. Management has determined that the revenue streams that will be impacted by the guidance relate to non-standard
