Overview	'
	NOTE A. OVERVIEW
	Overview
	Allison Transmission Holdings, Inc. and its subsidiaries (the “Company” or “Allison”), design and manufacture commercial and defense fully-automatic transmissions.
	The business was founded in 1915 and has been headquartered in Indianapolis, Indiana since inception. The Company has 13 different transmission product lines. Although approximately 77% of revenues were generated in North America in 2013, the Company has a global presence by serving customers in Europe, Asia, South America and Africa. The Company serves customers through an independent network of approximately 1,400 independent distributor and dealer locations worldwide.
	Since the introduction of the Company’s first fully-automatic transmission over 60 years ago, the Company’s products have gained acceptance in a wide variety of applications, including on-highway trucks (distribution, refuse, construction, fire and emergency), buses (primarily school, transit and hybrid-transit), motorhomes, off-highway vehicles and equipment (primarily energy, mining and construction) and defense vehicles (wheeled and tracked).

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	NOTE B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation and Principles of Consolidation
	The condensed consolidated financial statements as of and for the three months ended March 31, 2014 and 2013 have been prepared in accordance with accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation 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 statement 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 operations 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, 2013 as filed with the Securities and Exchange Commission (“SEC”) on February 24, 2014. The interim period financial results for the three 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, allowance for doubtful accounts, 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 liability, 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 July 2013, the Financial Accounting Standards Board (“FASB”) issued authoritative accounting guidance on the presentation of an unrecognized tax benefit when net operating loss (“NOL”) carryforwards exist. The guidance requires presentation of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for an NOL carryforward, a similar tax loss or a tax credit carryforward. The guidance became effective for fiscal years beginning after December 15, 2013. The adoption of this guidance did not have a material effect on the Company’s condensed consolidated financial statements.
	In March 2013, the FASB issued authoritative accounting guidance on a parent company’s accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. The guidance clarifies that when a parent company ceases to have a controlling financial interest in a subsidiary or group of assets, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The guidance became effective for fiscal years beginning after December 15, 2013. The adoption of this guidance did not have an effect on the Company’s condensed consolidated financial statements.

FAIR_VALUE_OF_FINANCIAL_INSTRU

FAIR VALUE OF FINANCIAL INSTRUMENTS	3 Months Ended
	Mar. 31, 2014
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 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 March 31, 2014 and December 31, 2013, 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, foreign currency forward contracts 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 fair value 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 qualifies 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 foreign currency contracts consist of forward rate contracts which are intended to hedge exposure of transactions denominated in certain currencies and reduce the impact of currency price volatility on the Company’s financial results. The commodity contracts 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 foreign currency derivatives, the Company uses forward foreign exchange rates received from the issuing financial institution. These rates are periodically corroborated by comparing to third-party broker quotes. The foreign currency hedges 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 generally does not elect to apply hedge accounting for these foreign currency contracts, 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 during the period of change.
	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 contracts, 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 March 31, 2014 and December 31, 2013 (dollars in millions):

	Less: current maturities of long-term debt		19.5		17.9
	Total long-term debt less current portion	$	2,656.00	$	2,660.40
	As of March 31, 2014, the Company had $423.5 million of indebtedness associated with Allison Transmission, Inc.’s (“ATI”), the Company’s wholly-owned subsidiary, Senior Secured Credit Facility Term B-2 Loan due 2017 (“Term B-2 Loan”) and $1,780.7 million of indebtedness associated with ATI’s Senior Secured Credit Facility Term B-3 Loan due 2019 (“Term B-3 Loan”) (together the Term B-2 Loan, Term B-3 Loan and revolving credit facility defined as the “Senior Secured Credit Facility”). The Company also had indebtedness of $471.3 million of ATI’s 7.125% senior cash pay notes due May 2019 (“7.125% Senior Notes”).
	The fair value of the Company’s long-term debt obligations as of March 31, 2014 was $2,720.3 million. The fair value is based on quoted Level 1 market prices of the Company’s debt as of March 31, 2014. 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
	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-2 Loan, as of March 31, 2014, is equal to the LIBOR plus 3.00% and interest on the Term B-3 Loan, as of March 31, 2014, is equal to the LIBOR (which may not be less than 1.00%) plus 2.75% based on the Company’s total leverage ratio. As of March 31, 2014, these rates were approximately 3.16% and 3.75% on the Term B-2 Loan and Term B-3 Loan, respectively, and the weighted average rate on the Senior Secured Credit Facility was approximately 3.64%. The Senior Secured Credit Facility requires minimum quarterly principal payments on the Term B-2 Loan and 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. Due to voluntary prepayments, the Company has fulfilled all Term B-2 Loan required quarterly payments through its maturity date of 2017. The minimum required quarterly principal payment on the Term B-3 Loan is $4.5 million and remains through its maturity date of 2019. As of March 31, 2014, 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 on each loan is due upon maturity.
	The Senior Secured Credit Facility also provides for revolving credit borrowings. In the first quarter of 2014, ATI increased the revolving commitments available under the revolving portion of the Senior Secured Credit Facility to $465.0 million, net of an allowance for up to $75.0 million in outstanding letters of credit commitments. The increase was treated as a modification of debt under GAAP, and thus the Company recorded $0.6 million of new deferred financing fees in the condensed consolidated financial statements. Throughout the three months ended March 31, 2014, the Company did not make any withdrawals on the revolving credit facility. As of March 31, 2014, the Company had $453.0 million available under the revolving credit facility, net of $12.0 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. As of March 31, 2014, this rate would have been between approximately 2.41% and 4.50%. In addition, there is an annual commitment fee, based on the Company’s total leverage ratio, which as of March 31, 2014, was equal to 0.375% of 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. On March 12, 2014, however, the revolving lenders holding a majority of the revolving loan commitments permanently waived and agreed that no event of default would result from any non-compliance so long as there were no revolving loans outstanding as of the last day of any fiscal quarter. As of March 31, 2014, 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 3.14x 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 our 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 March 31, 2014, the total leverage ratio was 3.86x.
	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 or declare or pay certain dividends. As of March 31, 2014, the Company is in compliance with all covenants under the Senior Secured Credit Facility.

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 forward contracts and commodity swaps. 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 March 31, 2014 and December 31, 2013 follows (dollars in millions):
		March 31, 2014								December 31, 2013

	Certain of the Company’s interest rate derivatives contain credit-risk and collateral contingent features under which downgrades in the Company’s credit rating could require the Company to increase its collateral. Certain interest rate derivatives also contain provisions under which the Company may be required to post additional collateral if the LIBOR interest rate curve reaches certain levels.
	As of March 31, 2014 and December 31, 2013, the Company had recorded cash collateral of $2.0 million and $1.7 million, respectively, in Other current assets in the Condensed Consolidated Balance Sheets, as the balances are subject to frequent change. The Company has also posted $2.0 million of collateral in the form of letters of credit.
	Currency Exchange
	The Company’s business is subject to foreign exchange rate risk. As a result, the Company enters into various forward rate contracts that qualify as derivatives under the authoritative accounting guidance to manage certain of these exposures. Forward contracts are used to hedge forecasted transactions and known exposure of payables denominated in a foreign currency. The Company generally has not elected to apply hedge accounting under the authoritative accounting guidance and recorded the unrealized fair value adjustments and realized gains and losses associated with these contracts in Other expense, net in the Condensed Consolidated Statements of Comprehensive Income during the period of change.
	The following table summarizes the outstanding foreign currency forward contracts as of March 31, 2014 and December 31, 2013 (amounts in millions):

	Commodity
	The Company’s business is subject to commodity price risk, primarily with component suppliers. As a result, the Company enters into various commodity swap contracts 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 contracts, 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.

	NOTE M. INCOME TAXES
	For the three months ended March 31, 2014 and 2013, the Company recorded total tax expense of $27.2 million and $16.9 million, respectively. The effective tax rate for the three months ended March 31, 2014 and 2013 was (34.4%) and (38.1%), respectively. The change in the effective rate was principally driven by a 2013 discrete expense item and a prior period statutory change in a state apportionment rate, resulting in a favorable tax benefit being recorded in the first quarter of 2014.
	During the first quarter 2014, the Company incurred an ownership change resulting in a limitation on the utilization of the Company’s net operating losses. The Company has reviewed the limitation and determined there is no concern about the Company’s ability to utilize the tax attributes in the future.
	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 carryforward 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 the 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 objectively measured positive evidence outweighed 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 recorded a liability of $2.3 million for unrecognized tax benefits related to the 2010 Research & Development Credit as of March 31, 2014 and December 31, 2013. 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. For the year ended December 31, 2013, the return 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).

Pursuant to an amended and restated stockholders agreement, a majority of the Board of Directors has been designated by the Sponsors and is affiliated with the Sponsors. As a result, the Sponsors or their nominees to the Board of Directors have the ability to control the appointment of management, the entering into of mergers, sales of substantially all of the Company’s assets and other extraordinary transactions and influence amendments to the Company’s certificate of incorporation. The interests of the Sponsors could conflict with those of the Company’s other stockholders. In addition, the Sponsors may in the future own businesses that directly compete with the Company.
	Senior Notes Held by Executive Officers
	As of March 31, 2014, Lawrence E. Dewey, our Chairman, President and Chief Executive Officer, and David S. Graziosi, our Executive Vice President, Chief Financial Officer and Treasurer held approximately $100,000 and $450,000, respectively, in aggregate principal amount of the 7.125% Senior Notes.

In connection with the offering, the Company repurchased from the underwriters 3,428,179 shares of the 28,750,000 shares at the price paid by the underwriters and subsequently retired those shares. The sale by the Sponsors resulted in their ownership falling below fifty percent of our outstanding common stock and the loss of controlled company status under the listing rules of the New York Stock Exchange.

EARNINGS PER SHARE	'
	NOTE Q. 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 following table reconciles the numerators and denominators used to calculate basic EPS and diluted EPS (in millions, except per share data):

	These condensed consolidated financial statements present the financial position, results of operations 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, 2013 as filed with the Securities and Exchange Commission (“SEC”) on February 24, 2014. The interim period financial results for the three 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, allowance for doubtful accounts, 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 liability, 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 July 2013, the Financial Accounting Standards Board (“FASB”) issued authoritative accounting guidance on the presentation of an unrecognized tax benefit when net operating loss (“NOL”) carryforwards exist. The guidance requires presentation of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for an NOL carryforward, a similar tax loss or a tax credit carryforward. The guidance became effective for fiscal years beginning after December 15, 2013. The adoption of this guidance did not have a material effect on the Company’s condensed consolidated financial statements.
	In March 2013, the FASB issued authoritative accounting guidance on a parent company’s accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. The guidance clarifies that when a parent company ceases to have a controlling financial interest in a subsidiary or group of assets, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The guidance became effective for fiscal years beginning after December 15, 2013. The adoption of this guidance did not have an effect on the Company’s condensed consolidated financial statements.
