SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	6 Months Ended

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 and Article 10 of Regulations S-X. Accordingly, the condensed consolidated financial statements do not include all information and footnotes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements. The information herein reflects all normal recurring material adjustments, which are, in the opinion of management, necessary for the fair statements of the results for the periods presented. The condensed consolidated financial statements herein consist of all wholly-owned domestic and foreign subsidiaries with all significant intercompany transactions eliminated. 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 for the year ended December 31, 2015 as filed with the Securities and Exchange Commission (“SEC”) on February 19, 2016. The Company revised its condensed consolidated statements of cash flows for the prior period due to changes in how foreign currency exchange rate movements on cash were calculated. The revision resulted in a decrease to the “Effect of exchange rate changes on cash” with a corresponding increase to “Net cash provided by operating activities” for the six months ended June 30, 2015. Management believes the revision is immaterial to the condensed consolidated financial statements. The revision had no impact on previously reported net income, total stockholders’ equity or cash. The interim period financial results for the three and six month periods presented are not necessarily indicative of results to be expected for any other interim period or for the entire year. 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. Significant 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. Recently Issued Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“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 will be effective for the Company in fiscal year 2017, but early adoption is permitted. In February 2016, the FASB issued authoritative accounting guidance on lease accounting. The guidance requires lessees to present right-of-use assets and lease liabilities on the balance sheet for all leases not considered short-term leases. Short-term leases are leases with a lease term of 12 months or less as long as the leases do not include options to purchase the underlying assets that the lessee is reasonably certain to exercise. The new guidance also introduces new disclosure requirements for leasing arrangements. The guidance will be effective for the Company in fiscal year 2019, but early adoption is permitted. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. 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) and the requirement for equity securities to be measured at fair value with changes in fair value recognized in net income. The guidance will be effective prospectively for the Company in fiscal year 2018 and early adoption is limited to certain provisions. Upon adoption, a cumulative-effect adjustment to retained earnings in the statement of financial position will be reclassified to beginning retained earnings in the year of adoption. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. 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 and the retail inventory method are not impacted by the new guidance. The guidance will be effective for the Company in fiscal year 2017, but can be early-adopted. Management is assessing the potential impact of the adoption of this guidance on the Company’s consolidated financial statements. In August 2014, the FASB issued authoritative accounting guidance on the disclosure of uncertainties about an entity’s ability to continue as a going concern. The guidance requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that financial statements are available to be issued when applicable) and to provide related footnote disclosures. The guidance became effective prospectively for the Company as of January 1, 2016. The adoption of this guidance did not have an effect on the Company’s condensed consolidated financial statements. In May 2014, the FASB issued authoritative accounting guidance on a company’s accounting for revenue from contracts with customers. 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 guidance will be effective for the Company for the annual and interim periods beginning January 1, 2018. Management is currently evaluating the impact this guidance will have on the Company’s revenue sources including assessing the impact of both methods of adoption on the Company’s consolidated financial statements.

FAIR VALUE OF FINANCIAL INSTRUM

FAIR VALUE OF FINANCIAL INSTRUMENTS	6 Months Ended
	Jun. 30, 2016
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 June 30, 2016 and December 31, 2015, 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 and cash equivalents, available-for-sale securities, derivative instruments, assets held in a rabbi trust and a deferred compensation obligation. The Company’s cash equivalents consist of short-term U.S. government backed securities. The Company’s available-for-sale securities consist of ordinary shares of Torotrak plc (“Torotrak”) associated with a license and exclusivity agreement with Torotrak. Torotrak’s listed shares are traded on the London Stock Exchange under the ticker symbol “TRK.” The Company’s derivative instruments consist of interest rate swaps and commodity swaps. The Company’s assets held in the rabbi trust consist principally of publicly available mutual funds and target date retirement funds. The Company’s deferred compensation obligation is directly related to the fair value of assets held in the rabbi trust. The Company’s valuation techniques used to calculate the fair value of cash and cash equivalents, available-for-sale securities, assets held in the rabbi trust and the deferred compensation obligation represent a market approach in active markets for identical assets that qualify as Level 1 in the fair value hierarchy. The Company’s valuation techniques used to calculate the fair value of derivative instruments represent a market approach with observable inputs that qualify as Level 2 in the fair value hierarchy. The commodity swaps consist of forward rate contracts which are intended to hedge exposure of transactions involving purchases of component parts and energy to power our facilities, reducing the impact of commodity price volatility on the Company’s financial results. For the fair value measurement of commodity derivatives, the Company uses forward prices received from the issuing financial institution. These rates are periodically corroborated by comparing to third-party broker quotes. The commodity derivatives are accounted for within the authoritative accounting guidance set forth on accounting for derivative instruments and hedging activities and have been recorded at fair value based upon quoted market rates. The fair values are included in Other current and non-current assets and liabilities in the Condensed Consolidated Balance Sheets. The Company has either not qualified for or not elected hedge accounting treatment for these commodity swaps, and as a result, unrealized fair value adjustments and realized gains and losses are recorded in Other expense, net in the Condensed Consolidated Statements of Comprehensive Income. For the fair value measurement of interest rate derivatives, the Company uses valuations from the issuing financial institution. The Company corroborates the valuation through the use of third-party valuation services using a standard replacement valuation model. The floating-to-fixed interest rate swaps are based on the London Interbank Offered Rate (“LIBOR”) which is observable at commonly quoted intervals. The fair values are included in other current and non-current assets and liabilities in the Condensed Consolidated Balance Sheets. The Company has not qualified for hedge accounting treatment for the interest rate swaps and, as a result, fair value adjustments are charged directly to Interest expense in the Condensed Consolidated Statements of Comprehensive Income. The following table summarizes the fair value of the Company’s financial assets and (liabilities) as of June 30, 2016 and December 31, 2015 (dollars in millions): Fair Value Measurements Using Quoted Prices in Active Significant Other TOTAL June 30, 2016 December 31, June 30, 2016 December 31, June 30, 2016 December 31, Cash equivalents $ 150.1 $ 100.0 $ — $ — $ 150.1 $ 100.0 Available-for-sale securities 2.9 2.9 — — 2.9 2.9 Rabbi trust assets 5.9 4.8 — — 5.9 4.8 Deferred compensation obligation (5.9 ) (4.8 ) — — (5.9 ) (4.8 ) Derivative assets — — 0.4 — 0.4 — Derivative liabilities — — (43.8 ) (30.1 ) (43.8 ) (30.1 ) Total $ 153.0 $ 102.9 $ (43.4 ) $ (30.1 ) $ 109.6 $ 72.8

DEBT

DEBT	6 Months Ended
	Jun. 30, 2016
DEBT	NOTE F. DEBT Long-term debt and maturities are as follows (dollars in millions): June 30, December 31, Long-term debt: Senior Secured Credit Facility Term B-3 Loan, variable, due 2019 $ 2,390.6 $ 2,402.8 Less: current maturities of long-term debt 24.5 24.5 deferred financing costs, net 22.2 25.6 Total long-term debt, net $ 2,343.9 $ 2,352.7 As of June 30, 2016, the Company had $2,390.6 million of indebtedness associated with Allison Transmission, Inc.’s (“ATI”), the Company’s wholly-owned subsidiary, Senior Secured Credit Facility Term B-3 Loan due 2019 (“Term B-3 Loan”, and together with the revolving credit facility, defined as the “Senior Secured Credit Facility”). The fair value of the Company’s long-term debt obligations as of June 30, 2016 was $2,387.6 million. The fair value is based on quoted Level 2 market prices of the Company’s debt as of June 30, 2016. 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. 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 Loan, as of June 30, 2016, is either (a) 2.50% over the LIBOR (which may not be less than 1.00%) or (b) 1.50% over the greater of the prime lending rate provided by the British Banking Association or the federal funds effective rate published by the Federal Reserve Bank of New York. As of June 30, 2016, the interest rate was approximately 3.50% on the Term B-3 Loan. The Senior Secured Credit Facility requires minimum quarterly principal payments on the Term B-3 Loan as well as prepayments from certain net cash proceeds of non-ordinary course asset sales and casualty and condemnation events and from a percentage of excess cash flow, if applicable. The minimum required quarterly principal payment on the Term B-3 Loan is $6.1 million and remains through its maturity date of August 2019. As of June 30, 2016, there had been no payments required for certain net cash proceeds of non-ordinary course asset sales and casualty and condemnation events. The remaining principal balance is due upon maturity. The Senior Secured Credit Facility also provides for a revolving credit borrowing. As of June 30, 2016, the Company had $462.4 million available under the revolving credit facility, net of $2.6 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. 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 Senior Secured 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 January 2019. The revolving portion of 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 at the end of a fiscal quarter. As of June 30, 2016, 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 2.98x ratio. Additionally within the terms of the Senior Secured Credit Facility, a senior secured leverage ratio at or below 3.50x 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. A total leverage ratio at or below 3.25x results in a 25 basis point reduction to the applicable margin on ATI’s Term B-3 Loan. These reductions would remain in effect as long as the Company achieves a total leverage ratio at or below the related threshold. As of June 30, 2016, the total leverage ratio was 2.98x. 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 June 30, 2016, the Company is in compliance with all covenants under the Senior Secured Credit Facility.

DERIVATIVES

DERIVATIVES	6 Months Ended
	Jun. 30, 2016
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. The Company has not elected hedge accounting treatment for these derivatives, and as a result, fair value adjustments are charged directly to Interest expense in the Condensed Consolidated Statements of Comprehensive Income. A summary of the Company’s interest rate derivatives as of June 30, 2016 and December 31, 2015 is as follows (dollars in millions): June 30, 2016 December 31, 2015 Notional Fair Value Notional Fair Value 3.44% Interest Rate Swap L, Aug 2016 – Aug 2019* $ 75.0 $ (5.0 ) $ 75.0 $ (3.6 ) 3.43% Interest Rate Swap M, Aug 2016 – Aug 2019* 100.0 (6.7 ) 100.0 (4.8 ) 3.37% Interest Rate Swap N, Aug 2016 – Aug 2019* 75.0 (4.9 ) 75.0 (3.5 ) 3.19% Interest Rate Swap O, Aug 2016 – Aug 2019* 75.0 (4.5 ) 75.0 (3.1 ) 3.08% Interest Rate Swap P, Aug 2016 – Aug 2019* 75.0 (4.2 ) 75.0 (2.8 ) 2.99% Interest Rate Swap Q, Aug 2016 – Aug 2019* 50.0 (2.7 ) 50.0 (1.7 ) 2.98% Interest Rate Swap R, Aug 2016 – Aug 2019* 50.0 (2.7 ) 50.0 (1.7 ) 2.73% Interest Rate Swap S, Aug 2016 – Aug 2019* 50.0 (2.3 ) 50.0 (1.4 ) 2.74% Interest Rate Swap T, Aug 2016 – Aug 2019* 75.0 (3.5 ) 75.0 (2.1 ) 2.66% Interest Rate Swap U, Aug 2016 – Aug 2019* 50.0 (2.2 ) 50.0 (1.2 ) 2.60% Interest Rate Swap V, Aug 2016 – Aug 2019* 50.0 (2.0 ) 50.0 (1.2 ) 2.40% Interest Rate Swap W, Aug 2016 – Aug 2019* 25.0 (0.9 ) 25.0 (0.5 ) 2.25% Interest Rate Swap X, Aug 2016 – Aug 2019* 50.0 (1.6 ) 50.0 (0.8 ) * includes LIBOR floor of 1.00% $ 800.0 $ (43.2 ) $ 800.0 $ (28.4 ) Commodity The Company’s business is subject to commodity price risk, primarily with component suppliers. As a result, the Company enters into various commodity swaps that qualify as derivatives under the authoritative accounting guidance to manage certain of these exposures. Swap contracts are used to hedge forecasted transactions either of the commodity or of components containing the commodity. The Company has not qualified for hedge accounting treatment for these commodity swaps, and as a result, unrealized fair value adjustments and realized gains and losses associated with these contracts were charged directly to Other expense, net in the Condensed Consolidated Statements of Comprehensive Income during the period of change.

INCOME TAXES

INCOME TAXES	6 Months Ended
	Jun. 30, 2016
INCOME TAXES	NOTE L. INCOME TAXES For the three and six months ended June 30, 2016, the Company recorded total tax expense of $38.3 million and $66.5 million, respectively. The effective tax rate for the three and six months ended June 30, 2016 and 2015 was 38.6% and 37.9%, respectively. For the three and six months ended June 30, 2015, the Company recorded total tax expense of $32.7 million and $72.5 million, respectively. The effective tax rate for the three and six months ended June 30, 2015 was 37.5% and 37.1%, respectively. The need to establish a valuation allowance against the deferred tax assets is assessed periodically based on a more-likely-than-not realization threshold, in accordance with authoritative accounting guidance. Appropriate consideration is given to all positive and negative evidence related to that realization. This assessment considers, among other matters, the nature, frequency and severity of recent losses, forecasts of future profitability, the duration of statutory carry forward periods, experience with tax attributes expiring unused, and tax planning alternatives. The weight given to these considerations depends upon the degree to which they can be objectively verified. The Company has determined, based on the evaluation of both objective and subjective evidence available, that a domestic valuation allowance is not necessary and that it is more likely than not that the deferred tax assets are fully realizable. The Company has reached a sustained period of profitability and believes its objectively measured positive evidence outweighs the negative evidence. The Company continues to provide for a valuation allowance on certain of its foreign deferred tax assets. 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 June 30, 2016 and December 31, 2015. 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

COMMITMENTS AND CONTINGENCIES	6 Months Ended
	Jun. 30, 2016
COMMITMENTS AND CONTINGENCIES	NOTE N. COMMITMENTS AND CONTINGENCIES Environmental Matters In accordance with the asset purchase agreement with Old GM, General Motors Company (“GM”), as successor to Old GM’s obligations, performed remediation activities relating to historical soil and groundwater contamination at the Company’s Indianapolis, Indiana manufacturing facilities (the “Corrective Action”) under a voluntary corrective action agreement with the U.S. Environmental Protection Agency (“EPA”). Pursuant to the asset purchase agreement, once the EPA issued a final decision on GM’s remediation plan for the Corrective Action, the Company would assume all responsibility for operating, monitoring and maintaining the Corrective Action. During the third quarter of 2015, the Company recorded approximately $14.0 million for the estimated undiscounted environmental liabilities related to the Corrective Action, to be paid out over the next 30 years, including approximately $0.5 million recorded to Other current liabilities and approximately $13.5 million to Other non-current liabilities. The Company expects to fund the expenditures for these activities from operating cash flow. During the first quarter of 2016, EPA issued a final decision and the Company assumed all responsibility for the Corrective Action. The EPA also asked the Company to enter into an administrative order of consent that requires the Company to provide financial assurance to complete the operation, monitoring and maintenance in the event the Company fails to do so. This financial assurance can take a variety of forms including, but not limited to meeting certain financial metrics, providing a letter of credit, or securing a bond or an insurance policy. The amount and method by which the Company will be required to provide financial assurance is expected to be determined in 2016. 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	6 Months Ended
	Jun. 30, 2016
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 that would be credited to additional paid-in-capital when the award generates a tax deduction. If there would be a shortfall resulting in a charge to additional paid-in-capital, 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 the three months and six months ended June 30, 2016 and 2015, 0.6 million outstanding anti-dilutive stock options were not included in the diluted EPS calculation because they were anti-dilutive. For the three months and six months ended June 30, 2015, 0.2 million outstanding anti-dilutive 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 Six months ended 2016 2015 2016 2015 Net income $ 60.8 $ 54.4 $ 109.1 $ 122.8 Weighted average shares of common stock outstanding 169.0 178.5 169.8 179.3 Dilutive effect stock-based awards 1.0 1.1 1.0 1.8 Diluted weighted average shares of common stock outstanding 170.0 179.6 170.8 181.1 Basic earnings per share attributable to common stockholders $ 0.36 $ 0.30 $ 0.64 $ 0.68 Diluted earnings per share attributable to common stockholders $ 0.36 $ 0.30 $ 0.64 $ 0.68

The Board authorized management to repurchase up to $500.0 million of its common stock on the open market or through privately negotiated transactions through December 31, 2016. The timing and amount of stock purchases are subject to market conditions and corporate needs. This stock repurchase program may be extended, modified, suspended or discontinued at any time at the Company’s discretion. During the three and six months ended June 30, 2016, the Company repurchased approximately $59.0 million and $92.3 million of its common stock under the repurchase program, respectively.

SUMMARY OF SIGNIFICANT ACCOUN22

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2016
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 and Article 10 of Regulations S-X. Accordingly, the condensed consolidated financial statements do not include all information and footnotes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements. The information herein reflects all normal recurring material adjustments, which are, in the opinion of management, necessary for the fair statements of the results for the periods presented. The condensed consolidated financial statements herein consist of all wholly-owned domestic and foreign subsidiaries with all significant intercompany transactions eliminated. 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 for the year ended December 31, 2015 as filed with the Securities and Exchange Commission (“SEC”) on February 19, 2016. The Company revised its condensed consolidated statements of cash flows for the prior period due to changes in how foreign currency exchange rate movements on cash were calculated. The revision resulted in a decrease to the “Effect of exchange rate changes on cash” with a corresponding increase to “Net cash provided by operating activities” for the six months ended June 30, 2015. Management believes the revision is immaterial to the condensed consolidated financial statements. The revision had no impact on previously reported net income, total stockholders’ equity or cash. The interim period financial results for the three and six month periods presented are not necessarily indicative of results to be expected for any other interim period or for the entire year.
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. Significant 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.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“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 will be effective for the Company in fiscal year 2017, but early adoption is permitted. In February 2016, the FASB issued authoritative accounting guidance on lease accounting. The guidance requires lessees to present right-of-use assets and lease liabilities on the balance sheet for all leases not considered short-term leases. Short-term leases are leases with a lease term of 12 months or less as long as the leases do not include options to purchase the underlying assets that the lessee is reasonably certain to exercise. The new guidance also introduces new disclosure requirements for leasing arrangements. The guidance will be effective for the Company in fiscal year 2019, but early adoption is permitted. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. 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) and the requirement for equity securities to be measured at fair value with changes in fair value recognized in net income. The guidance will be effective prospectively for the Company in fiscal year 2018 and early adoption is limited to certain provisions. Upon adoption, a cumulative-effect adjustment to retained earnings in the statement of financial position will be reclassified to beginning retained earnings in the year of adoption. Management is currently evaluating the impact of this guidance on the Company’s consolidated financial statements. 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 and the retail inventory method are not impacted by the new guidance. The guidance will be effective for the Company in fiscal year 2017, but can be early-adopted. Management is assessing the potential impact of the adoption of this guidance on the Company’s consolidated financial statements. In August 2014, the FASB issued authoritative accounting guidance on the disclosure of uncertainties about an entity’s ability to continue as a going concern. The guidance requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that financial statements are available to be issued when applicable) and to provide related footnote disclosures. The guidance became effective prospectively for the Company as of January 1, 2016. The adoption of this guidance did not have an effect on the Company’s condensed consolidated financial statements. In May 2014, the FASB issued authoritative accounting guidance on a company’s accounting for revenue from contracts with customers. 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 guidance will be effective for the Company for the annual and interim periods beginning January 1, 2018. Management is currently evaluating the impact this guidance will have on the Company’s revenue sources including assessing the impact of both methods of adoption on the Company’s consolidated financial statements.
