Interim Financial Statements
	1. Interim Financial Statements
	Business Overview
	Unless the context otherwise requires, the use of the terms “PAG,” “we,” “us,” and “our” in these Notes to the Consolidated Condensed Financial Statements refers to Penske Automotive Group, Inc. and its consolidated subsidiaries.
	We are an international transportation services company that operates automotive and commercial truck dealerships principally in the United States and Western Europe, and distributes commercial vehicles, diesel engines, gas engines, power systems and related parts and services principally in Australia and New Zealand.
	Retail Automotive Dealership.  We believe we are the second largest automotive retailer headquartered in the U.S. as measured by the $16.6 billion in total retail automotive dealership revenue we generated in 2014. As of March 31, 2015, we operated 328 automotive retail franchises, of which 180 franchises are located in the U.S. and 148 franchises are located outside of the U.S. The franchises outside the U.S. are located primarily in the U.K. In the three months ended March 31, 2015, we retailed and wholesaled more than 122,000 vehicles. We are diversified geographically, with 60% of our total retail automotive dealership revenues in the three months ended March 31, 2015 generated in the U.S. and Puerto Rico and 40% generated outside the U.S. We offer over 40 vehicle brands, with 72% of our retail automotive dealership revenue in the three months ended March 31, 2015 generated from premium brands, such as Audi, BMW, Mercedes-Benz and Porsche. Each of our dealerships offer a wide selection of new and used vehicles for sale. In addition to selling new and used vehicles, we generate higher-margin revenue at each of our dealerships through maintenance and repair services and the sale and placement of third-party finance and insurance products, third-party extended service and maintenance contracts and replacement and aftermarket automotive products. We operate these dealerships under franchise agreements with a number of automotive manufacturers and distributors which are subject to certain rights and restrictions typical of the industry.
	During the three months ended March 31, 2015, we acquired one U.S. retail automotive franchise, Land Rover Darien, in Connecticut which complements our existing franchises in Danbury, Fairfield and Greenwich, Connecticut.
	Retail Commercial Truck Dealership.  In November 2014, we acquired a controlling interest (91%) in a heavy and medium duty truck dealership group located in Texas, Oklahoma and New Mexico, which we have renamed Penske Commercial Vehicles US (“PCV US”). Prior to this transaction, we held a 32% interest in PCV US and accounted for this investment under the equity method. PCV US operates sixteen locations, including ten full-service dealerships offering principally Freightliner, Western Star, and Sprinter-branded trucks. Two of these locations, Freightliner of Chattanooga and Freightliner of Knoxville, were acquired in February 2015. PCV US also offers a full range of used trucks available for sale as well as service and parts departments, many of which are open 24 hours a day, seven days a week.
	Commercial Vehicle Distribution.  Since August 2013, we have been the exclusive importer and distributor of Western Star heavy duty trucks (a Daimler brand), MAN heavy and medium duty trucks and buses (a VW Group brand), and Dennis Eagle refuse collection vehicles, together with associated parts across Australia, New Zealand and portions of the Pacific. The business, known as Penske Commercial Vehicles Australia, distributes commercial vehicles and parts to a network of more than 70 dealership locations, including three company-owned retail commercial vehicle dealerships.
	In October 2014, we acquired MTU Detroit Diesel Australia Pty Ltd., a leading distributor of diesel and gas engines and power systems, representing MTU, Detroit Diesel, Mercedes-Benz Industrial, Allison Transmission and MTU Onsite Energy.  We have renamed this business Penske Power Systems. Penske Power Systems offers products across the on- and off-highway markets in Australia, New Zealand and the Pacific and supports full parts and aftersales service through a network of branches, field locations and independent dealers across the region. The on-highway portion of this business complements our existing Penske Commercial Vehicles Australia distribution business.
	Penske Truck Leasing. We hold a 9.0% limited partnership interest in Penske Truck Leasing Co., L.P. (‘‘PTL’’), a leading provider of transportation and supply chain services.
	Basis of Presentation
	The following unaudited consolidated condensed financial statements of PAG have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and disclosures normally included in our annual financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to the SEC rules and regulations. The information presented as of March 31, 2015 and for the three month periods ended March 31, 2015 and 2014 is unaudited, but includes all adjustments which our management believes to be necessary for the fair presentation of results for the periods presented. We have changed the presentation of revenue and cost of sales within the Consolidated Condensed Statements of Income to reflect the addition of the retail commercial truck dealership business for the current and comparative periods presented.  We have also identified the retail commercial truck dealership business as a new reportable segment and have retroactively presented the segment data for all periods presented within the segment information footnote. Additionally, the consolidated condensed financial statements for the prior periods have been revised for entities that have been treated as discontinued operations, and results for interim periods are not necessarily indicative of results to be expected for the year. These consolidated condensed financial statements should be read in conjunction with our audited financial statements for the year ended December 31, 2014, which are included as part of our Annual Report on Form 10-K.
	Recent Accounting Pronouncements
	In April 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) — Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” ASU No. 2014-08 changes the requirements for reporting discontinued operations to only allow presentation of a disposal of an entity or component of an entity as a discontinued operation if it represents a strategic shift that has (or will have) a major effect on an entity’s operations or financial results. We adopted this accounting standard update effective January 1, 2015. See “Assets Held for Sale and Discontinued Operations” below for additional discussion.
	In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” This ASU supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. ASU No. 2014-09 will require an entity to recognize revenue when it transfers promised goods or services to customers using a five-step model that requires entities to exercise judgment when considering the terms of the contracts. This ASU can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption. In April 2015, the FASB proposed a one-year deferral of the effective date from January 1, 2017 to January 1, 2018 but would allow for early adoption as of January 1, 2017. We are currently assessing the impact the adoption of this update will have on our consolidated financial position, results of operations, and cash flows.
	In April 2015, the FASB issued ASU No. 2015-03, “Interest — Imputation of Interest (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. This ASU is effective for us beginning after January 1, 2016. We are currently assessing the impact the adoption of this update will have on our consolidated financial position, results of operations, and cash flows.
	Assets Held for Sale and Discontinued Operations
	We classify an entity as held for sale in the period in which all of the following criteria are met:
		·		management, having the authority to approve the action, commits to a plan to sell the entity;
		·		the entity is available for immediate sale in its present condition;
		·		an active program to locate a buyer and other actions required to complete the plan to sell have been initiated;
		·		the sale is probable and transfer is expected to be completed within one year;
		·		the entity is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and
		·		actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.
	As discussed previously, in April 2014, the FASB issued ASU No. 2014-08 that changes the definition of a discontinued operation to include only those disposals of components of an entity or components of an entity that are classified as held for sale that represent a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. We adopted this accounting standard update effective January 1, 2015.
	Prior to the adoption of ASU No. 2014-08, we accounted for dispositions as discontinued operations when it was evident that the operations and cash flows of an entity being disposed of would be eliminated from ongoing operations and we would not have any significant continuing involvement in its operations. The results of operations for those entities that were classified as discontinued operations prior to adoption of ASU No. 2014-08 are included in Income (loss) from discontinued operations in the accompanying Consolidated Condensed Statements of Income for all periods presented and will continue to be reported within discontinued operations in the future. Beginning with disposals or entities classified as held for sale subsequent to January 1, 2015, only those that represent a strategic shift that has, or will have, a major impact on our operations and financial results will be included in discontinued operations.
	We had no entities newly classified as held for sale during the three months ended March 31, 2015. As such, the combined financial information presented below represents only retail automotive dealerships and our car rental business that were classified as discontinued operations prior to adoption of ASU No. 2014-08:
			Three Months Ended March 31,

	Total liabilities		$	43.3		$	132.7
	Divestitures
	In February 2015, we divested our car rental business which included Hertz car rental franchises in the Memphis, Tennessee market and certain markets throughout Indiana. We received proceeds of $17.8 million from the sale excluding sales of car rental vehicles. The results of operations of our car rental business are included in discontinued operations for the three months ended March 31, 2015 and 2014.
	Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The accounts requiring the use of significant estimates include accounts receivable, inventories, income taxes, intangible assets and certain reserves.
	Fair Value of Financial Instruments
	Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Accounting standards establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value and also establishes the following three levels of inputs that may be used to measure fair value:
	Level 1	Quoted prices in active markets for identical assets or liabilities
	Level 2	Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted market prices in markets that are not active; or model-derived valuations or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities
	Level 3	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities
	Our financial instruments consist of cash and cash equivalents, debt, floor plan notes payable, forward exchange contracts and interest rate swaps used to hedge future cash flows. Other than our fixed rate debt, the carrying amount of all significant financial instruments approximates fair value due either to length of maturity, the existence of variable interest rates that approximate prevailing market rates, or as a result of mark to market accounting.
	Our fixed rate debt consists of amounts outstanding under our senior subordinated notes and mortgage facilities. We estimate the fair value of our senior unsecured notes using quoted prices for the identical liability (Level 2), and we estimate the fair value of our mortgage facilities using a present value technique based on our current market interest rates for similar types of financial instruments (Level 2). A summary of the carrying values and fair values of our 5.75% senior subordinated notes, 5.375% senior subordinated notes and our fixed rate mortgage facilities are as follows:
			March 31, 2015						December 31, 2014
			Carrying Value			Fair Value			Carrying Value		Fair Value
	5.75% senior subordinated notes due 2022		$	550.0		$	580.3		$	550.0	$	558.4
	5.375% senior subordinated notes due 2024		300.0			309.8			300.0		306.0

	5. Vehicle Financing
	We finance substantially all of the commercial vehicles we purchase for distribution, new vehicles for retail sale and a portion of our used vehicle inventories for retail sale under floor plan and other revolving arrangements with various lenders, including the captive finance companies associated with automotive manufacturers. In the U.S., the floor plan arrangements are due on demand; however, we have not historically been required to repay floor plan advances prior to the sale of the vehicles that have been financed. We typically make monthly interest payments on the amount financed. Outside of the U.S., substantially all of the floor plan arrangements are payable on demand or have an original maturity of 90 days or less, and we are generally required to repay floor plan advances at the earlier of the sale of the vehicles that have been financed or the stated maturity.
	The agreements typically grant a security interest in substantially all of the assets of our dealership and distribution subsidiaries, and in the U.S., Australia and New Zealand are guaranteed or partially guaranteed by us. Interest rates under the arrangements are variable and increase or decrease based on changes in the prime rate, defined London Interbank Offered Rate (‘‘LIBOR’’), the Finance House Bank Rate, the Euro Interbank Offered Rate, or the Australian or New Zealand Bank Bill Swap Rate (‘‘BBSW’’). To date, we have not experienced any material limitation with respect to the amount or availability of financing from any institution providing us vehicle financing. We also receive non-refundable credits from certain of our vehicle manufacturers, which are treated as a reduction of cost of sales as vehicles are sold.
	The weighted average interest rate on floor plan borrowings was 1.4% for the three months ended March 31, 2015 and 1.7% for the three months ended March 31, 2014, including for 2014 the effect of the interest rate swap discussed in Note 8. We classify floor plan notes payable to a party other than the manufacturer of a particular new vehicle, and all floor plan notes payable relating to pre-owned vehicles, as floor plan notes payable—non-trade on our consolidated balance sheets and classify related cash flows as a financing activity on our consolidated statements of cash flows.

	U.S. Credit Agreement
	On May 1, 2015, we amended and restated our U.S. credit agreement (the “U.S. credit agreement”) with Mercedes-Benz Financial Services USA LLC and Toyota Motor Credit Corporation, principally to increase the revolving borrowing capacity from $450.0 million to $700.0 million, to extend the term through September of 2018, and to eliminate the term loan. The amounts previously owing under the term loan have been repaid using the expanded revolving capacity.
	As amended, the U.S. credit agreement provides for up to $700.0 million in revolving loans for working capital, acquisitions, capital expenditures, investments and other general corporate purposes, which includes $250.0 million in revolving loans solely for future U.S. acquisitions. The loans mature on the termination date of the facility which is September 30, 2018. The revolving loans bear interest at LIBOR plus 2.00%, subject to an incremental 1.50% for uncollateralized borrowings in excess of a defined borrowing base.
	The U.S. credit agreement is fully and unconditionally guaranteed on a joint and several basis by substantially all of our U.S. subsidiaries and contains a number of significant covenants that, among other things, restrict our ability to dispose of assets, incur additional indebtedness, repay other indebtedness, pay dividends, create liens on assets, make investments or acquisitions and engage in mergers or consolidations. We are also required to comply with specified financial and other tests and ratios, each as defined in the U.S. credit agreement including: a ratio of current assets to current liabilities, a fixed charge coverage ratio, a ratio of debt to stockholders’ equity and a ratio of debt to earnings before interest, taxes, depreciation and amortization (“EBITDA”). A breach of these requirements would give rise to certain remedies under the agreement, the most severe of which is the termination of the agreement and acceleration of the amounts owed.
	The U.S. credit agreement also contains typical events of default, including change of control, non-payment of obligations and cross-defaults to our other material indebtedness. Substantially all of our U.S. assets are subject to security interests granted to the lenders under the U.S. credit agreement. As of March 31, 2015, we had $88.0 million outstanding under our prior term loan and no outstanding revolver borrowings under the U.S. credit agreement.
	U.K. Credit Agreement
	Our subsidiaries in the U.K. (the “U.K. subsidiaries”) are party to a revolving credit agreement with the Royal Bank of Scotland plc (RBS) and BMW Financial Services (GB) Limited, and an additional demand overdraft line of credit with RBS (collectively, the “U.K. credit agreement”) to be used for working capital, acquisitions, capital expenditures, investments and general corporate purposes. In April 2015, we amended the U.K. credit agreement principally to increase the revolving borrowing capacity from £100.0 million to £150.0 million. The loans mature on the termination date of the facility, which is December 19, 2019. The revolving loans bear interest between defined LIBOR plus 1.35% and defined LIBOR plus 3.0% and the demand overdraft line of credit bears interest at the Bank of England Base Rate plus 1.75%. As of March 31, 2015, outstanding loans under the U.K. credit agreement amounted to £37.0 million ($54.8 million).
	The U.K. Credit Agreement is fully and unconditionally guaranteed on a joint and several basis by our U.K. subsidiaries, and contains a number of significant covenants that, among other things, restrict the ability of our U.K. subsidiaries to pay dividends, dispose of assets, incur additional indebtedness, repay other indebtedness, create liens on assets, make investments or acquisitions and engage in mergers or consolidations. In addition, our U.K. subsidiaries are required to comply with defined ratios and tests, including: a ratio of earnings before interest, taxes, amortization, and rental payments (“EBITAR”) to interest plus rental payments, a measurement of maximum capital expenditures, and a debt to EBITDA ratio. A breach of these requirements would give rise to certain remedies under the agreement, the most severe of which is the termination of the agreement and acceleration of any amounts owed.
	The U.K. credit agreement also contains typical events of default, including change of control and non-payment of obligations and cross-defaults to other material indebtedness of our U.K. subsidiaries. Substantially all of our U.K. subsidiaries’ assets are subject to security interests granted to the lenders under the U.K. credit agreement.
	In 2012, our U.K. subsidiaries entered into a separate agreement with RBS, as agent for National Westminster Bank plc, providing for a £30.0 million term loan which was used for working capital and an acquisition. The term loan is repayable in £1.5 million quarterly installments through 2015 with a final payment of £7.5 million due December 31, 2015. The term loan bears interest between 2.675% and 4.325%, depending on the U.K. subsidiaries’ ratio of net borrowings to earnings before interest, taxes, depreciation and amortization (as defined). As of March 31, 2015, the amount outstanding under the U.K. term loan was £10.5 million ($15.6 million).
	5.375% Senior Subordinated Notes
	In November 2014, we issued $300.0 million in aggregate principal amount of 5.375% Senior Subordinated Notes due 2024 (the “5.375% Notes”). Interest on the 5.375% Notes is payable semi-annually on June 1 and December 1 of each year. The 5.375% Notes mature on December 1, 2024, unless earlier redeemed or purchased by us. The 5.375% Notes are unsecured senior subordinated obligations and are guaranteed on an unsecured senior subordinated basis by our existing 100% owned U.S. subsidiaries. The 5.375% Notes also contain customary negative covenants and events of default.
	On or after December 1, 2019, we may redeem the 5.375% Notes for cash at the redemption prices noted in the indenture, plus any accrued and unpaid interest. We may also redeem up to 40% of the 5.375% Notes using the proceeds of specified equity offerings at any time prior to December 1, 2017 at a price specified in the indenture. If we experience certain “change of control” events specified in the indenture, holders of the 5.375% Notes will have the option to require us to purchase for cash all or a portion of their notes at a price equal to 101% of the principal amount of the notes, plus accrued and unpaid interest. In addition, if we make certain asset sales and do not reinvest the proceeds thereof or use such proceeds to repay certain debt, we will be required to use the proceeds of such asset sales to make an offer to purchase the notes at a price equal to 100% of the principal amount of the notes, plus accrued and unpaid interest.
	5.75% Senior Subordinated Notes
	In August 2012, we issued $550.0 million in aggregate principal amount of 5.75% Senior Subordinated Notes due 2022 (the “5.75% Notes”). Interest on the 5.75% Notes is payable semi-annually on April 1 and October 1 of each year. The 5.75% Notes mature on October 1, 2022, unless earlier redeemed or purchased by us. The 5.75% Notes are our unsecured senior subordinated obligations and are guaranteed on an unsecured senior subordinated basis by our existing 100% owned U.S. subsidiaries. The 5.75% Notes also contain customary negative covenants and events of default.
	On or after October 1, 2017, we may redeem the 5.75% Notes for cash at the redemption prices noted in the indenture, plus any accrued and unpaid interest. We may also redeem up to 40% of the 5.75% Notes using the proceeds of specified equity offerings at any time prior to October 1, 2015 at a price specified in the indenture. If we experience certain “change of control” events specified in the indenture, holders of the 5.75% Notes will have the option to require us to purchase for cash all or a portion of their notes at a price equal to 101% of the principal amount of the notes, plus accrued and unpaid interest. In addition, if we make certain asset sales and do not reinvest the proceeds thereof or use such proceeds to repay certain debt, we will be required to use the proceeds of such asset sales to make an offer to purchase the notes at a price equal to 100% of the principal amount of the notes, plus accrued and unpaid interest.
	U.S. Commercial Truck Capital Loan
	The principal source of working capital of our PCV US business was a working capital loan agreement with Mercedes-Benz Financial Services USA LLC with an amount outstanding of $60.5 million as of December 31, 2014. In February 2015, we repaid the outstanding principal balance using our U.S. revolving credit facility.
	Australia Working Capital Loan Agreement
	In December 2013, we entered into a working capital loan agreement with Mercedes-Benz Financial Services Australia Pty Ltd that provides us with up to AU $28.0 million ($21.3 million) of working capital availability. This agreement provides the lender with a secured interest in certain inventory and receivables of our commercial vehicle distribution business. The loan bears interest at the Australian BBSW 30-day Bill Rate plus 2.35%. As of March 31, 2015, no loans were outstanding under the working capital loan agreement.
	Mortgage Facilities
	We are party to several mortgages which bear interest at defined rates and require monthly principal and interest payments. These mortgage facilities also contain typical events of default, including non-payment of obligations, cross-defaults to our other material indebtedness, certain change of control events, and the loss or sale of certain franchises operated at the properties. Substantially all of the buildings and improvements on the properties financed pursuant to the mortgage facilities are subject to security interests granted to the lender. As of March 31, 2015, we owed $170.5 million of principal under our mortgage facilities.

	Our commercial vehicle distribution business sells vehicles, engines, parts and other products purchased from manufacturers in the U.S., Germany, and the U.K. In order to protect against exchange rate movements, we enter into foreign exchange forward contracts against anticipated cash flows. The contracts are timed to mature when major shipments are scheduled to arrive in Australia and when receipt of payment from customers is expected. We classify our foreign exchange forward contracts as cash flow hedges and state them at fair value. We used Level 2 inputs to estimate the fair value of the foreign exchange forward contracts. The fair value of the contracts designated as hedging instruments was estimated to be an asset of $1.5 million and $1.1 million as of March 31, 2015 and December 31, 2014, respectively.
	We previously were party to interest rate swap agreements through December 2014 pursuant to which the LIBOR portion of $300.0 million of our floating rate floor plan debt was fixed at a rate of 2.135% and $100.0 million of our floating rate floor plan debt was fixed at a rate of 1.55%. During the three months ended March 31, 2014, the swaps increased the weighted average interest rate on our floor plan borrowings by approximately 28 basis points. We are not party to any interest rate swap agreements as of March 31, 2015.

	We are involved in litigation which may relate to claims brought by governmental authorities, issues with customers, and employment related matters, including class action claims and purported class action claims. As of March 31, 2015, we were not party to any legal proceedings, including class action lawsuits that, individually or in the aggregate, are reasonably expected to have a material adverse effect on our results of operations, financial condition or cash flows. However, the results of these matters cannot be predicted with certainty, and an unfavorable resolution of one or more of these matters could have a material adverse effect on our results of operations, financial condition or cash flows.
	We have historically structured our operations so as to minimize ownership of real property. As a result, we lease or sublease substantially all of our facilities. These leases are generally for a period between five and 20 years, and are typically structured to include renewal options at our election. Pursuant to the leases for some of our larger facilities, we are required to comply with specified financial ratios, including a “rent coverage” ratio and a debt to EBITDA ratio, each as defined. For these leases, non-compliance with the ratios may require us to post collateral in the form of a letter of credit. A breach of the other lease covenants gives rise to certain remedies by the landlord, the most severe of which include the termination of the applicable lease and acceleration of the total rent payments due under the lease.
	We have sold a number of dealerships to third parties and, as a condition to certain of those sales, remain liable for the lease payments relating to the properties on which those businesses operate in the event of non-payment by the buyer. We are also party to lease agreements on properties that we no longer use in our retail operations that we have sublet to third parties. We rely on subtenants to pay the rent and maintain the property at these locations. In the event the subtenant does not perform as expected, we may not be able to recover amounts owed to us and we could be required to fulfill these obligations.
	We hold a 9.0% ownership interest in PTL. Historically, General Electric Capital Corporation (“GECC”) provided PTL with a majority of its financing though PTL has refinanced all of its GECC indebtedness. As part of that refinancing, we and the other PTL partners created a new company (“Holdings”), which, together with GECC, co-issued $700.0 million of 3.8% senior unsecured notes due 2019 (the “Holdings Bonds”). GECC agreed to be a co-obligor of the Holdings Bonds in order to achieve lower interest rates on the Holdings Bonds. Additional capital contributions from the members may be required to fund interest and principal payments on the Holdings Bonds to the extent Holdings is unable to pay those amounts. We have agreed to indemnify GECC for 9.0% of any principal or interest that GECC is required to pay on these bonds and pay GECC an annual fee of approximately $0.95 million for acting as obligor. The maximum amount of our obligations to GECC under this agreement is 9.0% of the required principal repayment due in 2019 (which is expected to be $63.1 million) and 9.0% of interest payments under the Holdings Bonds, plus fees and default interest, if any.
	In March 2015, Mitsui & Co. purchased a 20% ownership interest in PTL from GECC. PTL is currently owned 41.1% by Penske Corporation, 9.0% by us, 29.9% by GECC and 20.0% by Mitsui & Co.
	Our floor plan credit agreement with Mercedes Benz Financial Services Australia (“MBA”) provides us revolving loans for the acquisition of commercial vehicles for distribution to our retail network. This facility includes a limited parent guarantee and a commitment to repurchase dealer vehicles in the event the dealer’s floor plan agreement with MBA is terminated.
	We have $22.9 million of letters of credit outstanding as of March 31, 2015, and have posted $14.3 million of surety bonds in the ordinary course of business.

	Our operations are organized by management into operating segments by line of business and geography. We have determined that we have three reportable segments as defined in generally accepted accounting principles for segment reporting: (i) Retail Automotive, consisting of retail automotive dealership operations, (ii) Retail Commercial Truck, consisting of our U.S. retail commercial truck dealership operations, and (iii) Other, consisting of our commercial vehicle distribution operations and our investments in non-automotive retail operations. The Retail Automotive reportable segment includes all automotive dealerships and all departments relevant to the operation of the dealerships and the retail automotive joint ventures. The individual dealership operations included in the Retail Automotive reportable segment have been grouped into four geographic operating segments: Eastern, Central, and Western United States and International. The geographic operating segments have been aggregated into one reportable segment as their operations (A) have similar economic characteristics (all are automotive dealerships having similar margins), (B) offer similar products and services (all sell new and used vehicles, service, parts and third-party finance and insurance products), (C) have similar target markets and customers (generally individuals) and (D) have similar distribution and marketing practices (all distribute products and services through dealership facilities that market to customers in similar fashions).

Interim Financial Statements.
Basis of Presentation
	Basis of Presentation
	The following unaudited consolidated condensed financial statements of PAG have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and disclosures normally included in our annual financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to the SEC rules and regulations. The information presented as of March 31, 2015 and for the three month periods ended March 31, 2015 and 2014 is unaudited, but includes all adjustments which our management believes to be necessary for the fair presentation of results for the periods presented. We have changed the presentation of revenue and cost of sales within the Consolidated Condensed Statements of Income to reflect the addition of the retail commercial truck dealership business for the current and comparative periods presented.  We have also identified the retail commercial truck dealership business as a new reportable segment and have retroactively presented the segment data for all periods presented within the segment information footnote. Additionally, the consolidated condensed financial statements for the prior periods have been revised for entities that have been treated as discontinued operations, and results for interim periods are not necessarily indicative of results to be expected for the year. These consolidated condensed financial statements should be read in conjunction with our audited financial statements for the year ended December 31, 2014, which are included as part of our Annual Report on Form 10-K.
Recent Accounting Pronouncements
	Recent Accounting Pronouncements
	In April 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) — Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” ASU No. 2014-08 changes the requirements for reporting discontinued operations to only allow presentation of a disposal of an entity or component of an entity as a discontinued operation if it represents a strategic shift that has (or will have) a major effect on an entity’s operations or financial results. We adopted this accounting standard update effective January 1, 2015. See “Assets Held for Sale and Discontinued Operations” below for additional discussion.
	In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” This ASU supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. ASU No. 2014-09 will require an entity to recognize revenue when it transfers promised goods or services to customers using a five-step model that requires entities to exercise judgment when considering the terms of the contracts. This ASU can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption. In April 2015, the FASB proposed a one-year deferral of the effective date from January 1, 2017 to January 1, 2018 but would allow for early adoption as of January 1, 2017. We are currently assessing the impact the adoption of this update will have on our consolidated financial position, results of operations, and cash flows.
	In April 2015, the FASB issued ASU No. 2015-03, “Interest — Imputation of Interest (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. This ASU is effective for us beginning after January 1, 2016. We are currently assessing the impact the adoption of this update will have on our consolidated financial position, results of operations, and cash flows.
Assets Held For Sale and Discontinued Operations
	Assets Held for Sale and Discontinued Operations
	We classify an entity as held for sale in the period in which all of the following criteria are met:
		·		management, having the authority to approve the action, commits to a plan to sell the entity;
		·		the entity is available for immediate sale in its present condition;
		·		an active program to locate a buyer and other actions required to complete the plan to sell have been initiated;
		·		the sale is probable and transfer is expected to be completed within one year;
		·		the entity is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and
		·		actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.
	As discussed previously, in April 2014, the FASB issued ASU No. 2014-08 that changes the definition of a discontinued operation to include only those disposals of components of an entity or components of an entity that are classified as held for sale that represent a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. We adopted this accounting standard update effective January 1, 2015.
	Prior to the adoption of ASU No. 2014-08, we accounted for dispositions as discontinued operations when it was evident that the operations and cash flows of an entity being disposed of would be eliminated from ongoing operations and we would not have any significant continuing involvement in its operations. The results of operations for those entities that were classified as discontinued operations prior to adoption of ASU No. 2014-08 are included in Income (loss) from discontinued operations in the accompanying Consolidated Condensed Statements of Income for all periods presented and will continue to be reported within discontinued operations in the future. Beginning with disposals or entities classified as held for sale subsequent to January 1, 2015, only those that represent a strategic shift that has, or will have, a major impact on our operations and financial results will be included in discontinued operations.
	We had no entities newly classified as held for sale during the three months ended March 31, 2015. As such, the combined financial information presented below represents only retail automotive dealerships and our car rental business that were classified as discontinued operations prior to adoption of ASU No. 2014-08:

Divestitures
	Divestitures
	In February 2015, we divested our car rental business which included Hertz car rental franchises in the Memphis, Tennessee market and certain markets throughout Indiana. We received proceeds of $17.8 million from the sale excluding sales of car rental vehicles. The results of operations of our car rental business are included in discontinued operations for the three months ended March 31, 2015 and 2014.
Estimates
	Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The accounts requiring the use of significant estimates include accounts receivable, inventories, income taxes, intangible assets and certain reserves.
Fair Value of Financial Instruments
	Fair Value of Financial Instruments
	Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Accounting standards establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value and also establishes the following three levels of inputs that may be used to measure fair value:
	Level 1	Quoted prices in active markets for identical assets or liabilities
	Level 2	Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted market prices in markets that are not active; or model-derived valuations or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities
	Level 3	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities
	Our financial instruments consist of cash and cash equivalents, debt, floor plan notes payable, forward exchange contracts and interest rate swaps used to hedge future cash flows. Other than our fixed rate debt, the carrying amount of all significant financial instruments approximates fair value due either to length of maturity, the existence of variable interest rates that approximate prevailing market rates, or as a result of mark to market accounting.
	Our fixed rate debt consists of amounts outstanding under our senior subordinated notes and mortgage facilities. We estimate the fair value of our senior unsecured notes using quoted prices for the identical liability (Level 2), and we estimate the fair value of our mortgage facilities using a present value technique based on our current market interest rates for similar types of financial instruments (Level 2). A summary of the carrying values and fair values of our 5.75% senior subordinated notes, 5.375% senior subordinated notes and our fixed rate mortgage facilities are as follows:
			March 31, 2015						December 31, 2014
			Carrying Value			Fair Value			Carrying Value		Fair Value
	5.75% senior subordinated notes due 2022		$	550.0		$	580.3		$	550.0	$	558.4
