Interim Financial Statements.
Interim Financial Statements	1. Interim Financial Statements ​ 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. ​ Business Overview and Concentrations ​ We are a diversified international transportation services company and one of the world's premier automotive and commercial truck retailers. PAG operates dealerships principally in the United States, the United Kingdom, Canada, Germany, and Italy and is the largest retailer of commercial trucks in North America for Freightliner. PAG also distributes and retails commercial vehicles, diesel and gas engines, power systems, and related parts and services principally in Australia and New Zealand. Additionally, PAG owns 28.9% of Penske Transportation Solutions, a business that manages a fleet of over 330,000 vehicles providing innovative transportation, supply chain, and technology solutions to North American fleets. ​ Retail Automotive. ​ We also operate Used Vehicle SuperCenters in the U.S. and the U.K. which retail and wholesale used vehicles under a one price, “no-haggle” methodology under the CarShop brand. Our operations in the U.S. consist of seven retail locations operating in Pennsylvania and New Jersey. Our operations in the U.K. consist of twelve retail locations and a vehicle preparation center. During the second quarter of 2021, we opened one CarShop location in the U.S. and one in the U.K. ​ During the six months ended June 30, 2021, we acquired one retail automotive franchise in the U.S., were awarded one retail automotive franchise in the U.S., and disposed of one retail automotive franchise in the U.K. ​ Retail Commercial Truck Dealership. ​ Penske Australia ​ Penske Transportation Solutions. ​ Basis of Presentation ​ The accompanying 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 (“U.S. GAAP”) have been condensed or omitted pursuant to the SEC rules and regulations. The information presented as of June 30, 2021, and December 31, 2020, and for the three and six month periods ended June 30, 2021, and 2020 is unaudited but includes all adjustments which our management believes to be necessary for the fair presentation of results for the periods presented. 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, 2020, which are included as part of our Annual Report on Form 10-K. ​ Estimates ​ The preparation of financial statements in accordance 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 our fixed rate debt is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ December 31, 2020 ​ Carrying Value Fair Value Carrying Value Fair Value 3.50% senior subordinated notes due 2025 ​ ​ 544.0 ​ ​ 564.1 ​ ​ 543.2 ​ $ 554.6 ​ 3.75% senior subordinated notes due 2029 ​ ​ 493.9 ​ ​ 498.2 ​ ​ — ​ ​ — ​ Mortgage facilities ​ 398.9 ​ 406.5 ​ 458.1 ​ 474.7 ​ ​ During the second quarter of 2021, we issued $500 million in aggregate principal amount of 3.75% senior subordinated notes due 2029, the proceeds of which were used to redeem our $500 million in aggregate principal amount of 5.50% senior subordinated notes due 2026 on June 24, 2021. Refer to Note 9 “Long-Term Debt” for further discussion. ​ Discontinued Operations ​ We had no entities newly classified as held for sale during the six months ended June 30, 2021, or 2020 that met the criteria to be classified as discontinued operations. ​ Disposals ​ During the six months ended June 30, 2021, we disposed of one retail automotive franchise. The results of operations for this business are included within continuing operations for the three and six months ended June 30, 2021, and 2020 as this franchise did not meet the criteria to be classified as held for sale and treated as discontinued operations. ​ Income Taxes Tax regulations may require items to be included in our tax return at different times than when those items are reflected in our financial statements. Some of the differences are permanent, such as expenses that are not deductible on our tax return, and some are temporary differences, such as the timing of depreciation expense. Temporary differences create deferred tax assets and liabilities. Deferred tax assets generally represent items that will be used as a tax deduction or credit in our tax return in future years which we have already recorded in our financial statements. Deferred tax liabilities generally represent deductions taken on our tax return that have not yet been recognized as an expense in our financial statements. We establish valuation allowances for our deferred tax assets if the amount of expected future taxable income is not more likely than not to allow for the use of the deduction or credit. ​ Recent Accounting Pronouncements ​ Reference Rate Reform ​ In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This ASU provides optional guidance for a limited time to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. Additionally, entities can elect to continue applying hedge accounting for hedging relationships affected by reference rate reform if certain conditions are met. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” This ASU refines the scope of ASC 848 and clarifies some of its guidance as part of the Board’s monitoring of global reference rate reform activities. The ASU permits entities to elect certain optional expedients and exceptions when accounting for derivative contracts and certain hedging relationships affected by changes in the interest rates used for discounting cash flows, for computing variation margin settlements, and for calculating price alignment interest in connection with reference rate reform activities. These new standards were effective upon issuance and generally can be applied to applicable contract modifications through December 31, 2022. Our senior secured revolving credit facilities in the U.S. and U.K. and many of our floorplan arrangements utilize LIBOR as a benchmark for calculating the applicable interest rate. We are currently evaluating the impact of the transition from LIBOR to alternative reference interest rates. We cannot predict the effect of the potential changes to or elimination of LIBOR, the establishment and use of alternative rates or benchmarks, and the corresponding effects on our cost of capital but do not expect a significant impact on our consolidated financial position, results of operations, and cash flows. ​ Disclosures for Business Acquisitions, Dispositions, and Significant Subsidiaries ​ On May 20, 2020, the SEC issued a final rule that amends the financial statement requirements for acquisitions and dispositions of businesses, including the determinations of whether a subsidiary or an acquired or disposed business is significant. The significance test rule changes to SEC Regulation S-X, Rule 3-09 impact our disclosure requirements for equity method investments, including our investment in Penske Transportation Solutions (“PTS”) as it relates to providing audited financial statements and summarized financial statement information in our footnotes disclosures. The rule is effective January 1, 2021, but earlier compliance is permitted. The Company early adopted this rule in the fourth quarter of 2020.

Revenues.
Revenues	2. Revenues ​ Automotive and commercial truck dealerships generate the majority of our revenues. New and used vehicle revenues typically include sales to retail customers, to fleet customers, and to leasing companies providing consumer leasing. We generate finance and insurance revenues from sales of third-party extended service contracts, sales of third-party insurance policies, commissions relating to the sale of finance and lease contracts to third parties, and the sales of certain other products. Service and parts revenues include fees paid by customers for repair, maintenance and collision services, ​ Retail Automotive and Retail Commercial Truck Dealership Revenue Recognition Dealership Vehicle Sales. reduced by any noncash consideration representing the fair value of trade-in vehicles, if applicable. Payment is typically due and collected within 30 days subsequent to transfer of control of the vehicle. ​ Dealership Parts and Service Sales. We record revenue for vehicle service and collision work over time as work is completed and when parts are delivered to our customers. For service and parts revenues recorded over time, we utilize a method that considers total costs incurred to date and the applicable margin in relation to total expected efforts to complete our performance obligation in order to determine the appropriate amount of revenue to recognize over time. Recognition of this revenue over time reflects the amount of consideration we expect to be entitled to for the transfer of goods and services performed to date, representative of the amount for which we have a right to payment. The amount of consideration we receive for parts and service sales, including collision repair work, is based upon labor hours expended and parts utilized to perform and complete the necessary services to our customers. Payment is typically due upon delivery or within a period of time shortly thereafter. We receive payment from our customers upon transfer of control or within a period typically less than 30 days subsequent to the completion of services for the customer. We allow for customer returns of parts sales up to 30 days after the sale; however, parts returns are not material. Dealership Finance and Insurance Sales. Subsequent to the sale of a vehicle to a customer, we sell installment sale contracts to various financial institutions on a non-recourse basis (with specified exceptions) to mitigate the risk of default. We receive a commission from the lender equal to either the difference between the interest rate charged to the customer and the interest rate set by the financing institution or a flat fee. We also receive commissions for facilitating the sale of various products to customers, including guaranteed vehicle protection insurance, vehicle theft protection, and extended service contracts. These commissions are recorded as revenue at a point in time when the customer enters into the contract. Payment is typically due and collected within 30 days subsequent to the execution of the contract with the customer. ​ In the case of finance contracts, a customer may prepay or fail to pay their contract, thereby terminating the contract. Customers may also terminate extended service contracts and other insurance products, which are fully paid at purchase, and become eligible for refunds of unused premiums. In these circumstances, a portion of the commissions we received may be charged back based on the terms of the contracts. The revenue we record relating to these transactions is net of an estimate of the amount of chargebacks we will be required to pay. Our estimate is based upon our historical experience with similar contracts, including the impact of refinance and default rates on retail finance contracts and cancellation rates on extended service contracts and other insurance products. Aggregate reserves relating to chargeback activity were $31.0 million and $28.7 million as of June 30, 2021, and December 31, 2020, respectively. ​ Commercial Vehicle Distribution Revenue Recognition Penske Australia. The amount of consideration we receive for vehicle and product sales is stated within the executed contract with our customer. The amount of consideration we receive for parts and service sales is based upon labor hours expended and parts utilized to perform and complete the necessary services to our customers. Payment is typically due upon delivery, upon invoice, or within a period of time shortly thereafter. We receive payment from our customers upon transfer of control or within a period typically less than 30 days subsequent to transfer of control or invoice. We record revenue from the distribution of engines and other products at a point in time when delivered, which is when the transfer of title, risks and rewards of ownership, and control are considered passed to the customer. We record revenue for service or repair work applicable margin in relation to total expected efforts to complete our performance obligation in order to determine the appropriate amount of revenue to recognize over time. Recognition of revenue over time reflects the amount of consideration we expect to be entitled to for the transfer of goods and services performed to date, representative of the amount for which we have a right to payment. For our long-term power generation contracts, we record revenue over time as services are provided in accordance with contract milestones, which is considered an output method that requires judgment to determine our progress towards contract completion and the corresponding amount of revenue to recognize. Any revisions to estimates related to revenues or costs to complete contracts are recorded in the period in which the revisions to estimates are identified and the amounts can be reasonably estimated. The amount of consideration we receive for engine, product, and power generation sales is stated within the executed contract with our customer. The amount of consideration we receive for service sales is based upon labor hours expended and parts utilized to perform and complete the necessary services to our customers. Payment is typically due upon delivery, upon invoice, or within a period of time shortly thereafter. We receive payment from our customers upon transfer of control or within a period typically less than 30 days subsequent to transfer of control or invoice. ​ Service and parts revenue represented $72.0 million and $140.0 million for the three and six months ended June 30, 2021, and $51.0 million and $100.9 million for the three and six months ended June 30, 2020, respectively, for Penske Australia.

Leases

Leases
Leases	3. Leases ​ We lease land and facilities, including certain dealerships and office space. Our property leases are generally for an initial period between 5 and 20 years and are typically structured to include renewal options at our election. We include renewal options that we are reasonably certain to exercise in the measurement of our lease liabilities and right-of-use assets. We also have equipment leases that primarily relate to office and computer equipment, service and shop equipment, company vehicles, and other miscellaneous items. These leases are generally for a period of less than 5 years . We do not have any material leases, individually or in the aggregate, classified as a finance leasing arrangement. ​ We estimate the total undiscounted rent obligations under these leases, including any extension periods that we are reasonably certain to exercise, to be $5.5 billion as of June 30, 2021. Some of our lease arrangements include rental payments that are adjusted based on an index or rate, such as the Consumer Price Index (CPI). As the rate implicit in the lease is generally not readily determinable for our operating leases, the discount rates used to determine the present value of our lease liability are based on our incremental borrowing rate at the lease commencement date and commensurate with the remaining lease term. Our incremental borrowing rate for a lease is the rate of interest we would have to pay to borrow on a collateralized basis over a similar term for an amount equal to the lease payments in a similar economic environment. Leases with an initial term of 12 months or less are not recorded on the balance sheet. ​ 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. ​ In connection with the sale, relocation, and closure of certain of our franchises, we have entered into a number of third-party sublease agreements. The rent paid by our sub-tenants on such properties was $6.7 million and $13.0 million for the three and six months ended June 30, 2021, and $6.5 million and $12.9 million for the three and six months ended June 30, 2020, respectively. We have in the past and may in the future enter into sale-leaseback transactions to finance certain property acquisitions and capital expenditures, pursuant to which we sell property to third parties and agree to lease those assets back for a certain period of time. Such sales generate proceeds that vary from period to period. We had no proceeds from sale-leaseback transactions during the six months ended June 30, 2021, and 2020, respectively. We do not have any material leases that have not yet commenced as of June 30, 2021. ​ The following table summarizes our net operating lease cost during the three and six months ended June 30, 2021, and 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended June 30, ​ Six Months Ended June 30, ​ 2021 2020 2021 2020 Lease Cost ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Operating lease cost ​ $ 62.8 ​ $ 60.5 ​ $ 124.3 ​ $ 120.5 Sublease income ​ ​ (6.7) ​ ​ (6.5) ​ ​ (13.0) ​ ​ (12.9) Total lease cost ​ $ 56.1 ​ $ 54.0 ​ $ 111.3 ​ $ 107.6 (1) Includes short-term leases and variable lease costs, which are immaterial. ​ The following table summarizes supplemental cash flow information related to our operating leases: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six Months Ended ​ Six Months Ended ​ June 30, 2021 ​ June 30, 2020 Other Information ​ ​ ​ ​ ​ ​ Cash paid for amounts included in the measurement of lease liabilities ​ ​ ​ ​ ​ ​ Operating cash flows from operating leases ​ ​ 124.6 ​ ​ 114.3 Right-of-use assets obtained in exchange for operating lease liabilities ​ ​ 64.2 ​ ​ 2.6 ​ Supplemental balance sheet information related to the weighted average remaining lease term and discount rate of our leases is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ ​ December 31, 2020 Lease Term and Discount Rate ​ ​ ​ ​ ​ ​ Weighted-average remaining lease term - operating leases ​ ​ 24 years ​ ​ 25 years Weighted-average discount rate - operating leases ​ ​ 6.2% ​ ​ 6.4% ​ The following table summarizes the maturity of our lease liabilities on an undiscounted cash flow basis and a reconciliation to the operating lease liabilities recognized on our consolidated condensed balance sheet as of June 30, 2021: ​ ​ ​ ​ ​ Maturity of Lease Liabilities ​ June 30, 2021 2021 ​ $ 131.2 2022 ​ 249.4 2023 ​ 241.4 2024 ​ 234.7 2025 ​ ​ 231.1 2026 ​ ​ 221.2 2027 and thereafter ​ 4,198.1 Total future minimum lease payments ​ $ 5,507.1 Less: Imputed interest ​ ​ (3,036.2) Present value of future minimum lease payments ​ $ 2,470.9 ​ ​ ​ ​ Current operating lease liabilities (2) ​ $ 95.4 Long-term operating lease liabilities ​ ​ 2,375.5 Total operating lease liabilities ​ $ 2,470.9 (1) Excludes the six months ended June 30, 2021.

Vehicle Financing	7. 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 Base Rate, the Euro Interbank Offered Rate, the Canadian Prime Rate, the Australian Bank Bill Swap Rate (“BBSW”), or the New Zealand Bank Bill Benchmark Rate. 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 1.2% and 1.6% for the six months ended June 30, 2021, and 2020, respectively. 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.

The U.S. credit agreement provides for a maximum of $150.0 million of borrowings for foreign acquisitions and expires on September 30, 2023. The interest rate on revolving loans is LIBOR plus 1.75% , subject to an incremental 1.25% for uncollateralized borrowings in excess of a defined borrowing base. On April 28, 2021, we amended the U.S. credit agreement to incorporate the previous six amendments, to consolidate the $250 million acquisition line referenced above into the general revolving line (leaving us unchanged at $800 million in total revolving capacity), and to provide us with additional covenant flexibility. ​ 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 operating covenants that, among other things, restrict our ability to dispose of assets, incur additional indebtedness, repay certain 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 June 30, 2021, we had 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 £150.0 million revolving credit agreement with the National Westminster Bank plc and BMW Financial Services (GB) Limited plus an additional £52.0 million of demand overdraft lines of credit, £40.0 million of which is only available on demand from March 20th to April 30th and September 20th to October 31st each year (relating to the peak sales periods in the U.K.), (collectively, the “U.K. credit agreement”) to be used for working capital, acquisitions, capital expenditures, investments, and general corporate purposes. The loans mature on the termination date of the facility, which is December 12, 2023. The revolving loans bear interest between defined LIBOR plus 1.10% and defined LIBOR plus 2.10%. The U.K. credit agreement also includes a £100.0 million “accordion” feature which allows the U.K. subsidiaries to request up to an additional £100.0 million of facility capacity. The lenders may agree to provide the additional capacity, and if not, the U.K. subsidiaries may add an additional lender, if available, to the facility to provide such additional capacity. As of June 30, 2021, we had no outstanding revolver borrowings under the U.K. credit agreement. ​ 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. ​ Senior Subordinated Notes ​ We have issued the following senior subordinated notes: ​ ​ ​ ​ ​ ​ ​ ​ Description Maturity Date Interest Payment Dates ​ Principal Amount 3.50% Notes ​ September 1, 2025 ​ February 15, August 15 ​ $550 million 3.75% Notes June 15, 2029 ​ June 15, December 15 ​ $500 million ​ Each of these notes are our unsecured, senior subordinated obligations and are guaranteed on an unsecured senior subordinated basis by our 100% owned U.S. subsidiaries. Each also contain customary negative covenants and events of default. If we experience certain “change of control” events specified in the indentures, holders of these 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. ​ Optional redemption. we may redeem up to 40% of the 3.50% Notes before September 1, 2022, with net cash proceeds from certain equity offerings at a redemption price equal to 103.50% of the principal thereof, plus accrued and unpaid interest. On or after September 1, 2022, we may redeem the 3.50% Notes at the redemption prices noted in the indenture. Prior to June 15, 2024, we may redeem the 3.75% Notes at a redemption price equal to 100% of the principal thereof, plus an applicable make-whole premium, and any accrued and unpaid interest. In addition, we may redeem up to 40% of the Notes before June 15, 2024 with net cash proceeds from certain equity offerings at a redemption price equal to 103.750% of the principal thereof, plus accrued and unpaid interest. We may redeem the 3.75% Notes on or after June 15, 2024 at the redemption prices specified in the indenture. ​ Australia Loan Agreements ​ Penske Australia is party to two facilities with Volkswagen Financial Services Australia Pty Limited representing a five-year AU $50.0 million capital loan and a one-year AU $50.0 million working capital loan. Both facilities are subject to annual extensions. These agreements each provide the lender with a secured interest in all assets of these businesses. The loans bear interest at the Australian BBSW 30-day Bill Rate plus 3.0% . Irrespective of the term of the agreements, both agreements provide the lender with the ability to call the loans on 90 days’ notice. These facilities are also guaranteed by our U.S. parent company up to AU $50.0 million. As of June 30, 2021, we had AU $39.1 million ( $29.3 million) outstanding under the capital loan agreement and AU $ 10.0 million ($ 7.5 million) outstanding under the working capital loan agreement. ​ Mortgage Facilities ​ We are party to several mortgages that 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 June 30, 2021, we owed $398.9 million of principal under our mortgage facilities.

Derivatives and Hedging
Derivatives and Hedging	10. Derivatives and Hedging ​ Penske Australia 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, Penske Australia enters 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 record them at fair value. We use 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 $1.1 million and a liability of $2.5 million as of June 30, 2021, and December 31, 2020, respectively. ​ The Company periodically uses interest rate swaps to manage interest rate risk associated with the Company’s variable rate floor plan debt. In April 2020, we entered into a five-year interest rate swap agreement pursuant to which the LIBOR portion of $300.0 million of our U.S. floating rate floor plan debt is fixed at 0.5875% . This arrangement is in effect through April 2025. We may terminate this arrangement at any time, subject to the settlement at that time of the fair value of the swap arrangement. ​ The interest rate swap is designated as a cash flow hedge, and the related gain or loss is deferred in stockholders’ equity as a component of Accumulated Other Comprehensive Income (Loss). Monthly contractual settlements of the position are recognized as Floorplan interest expense, net, in the Condensed Consolidated Statements of Operations. We had no gain or loss related to ineffectiveness recognized in the Condensed Consolidated Statements of Operations during the three and six months ended June 30, 2021. We use Level 2 inputs to estimate the fair value of the interest rate swap agreement. The fair value of the swap designated as a hedging instrument was estimated to be a net asset of $0.4 million as of June 30, 2021, and a net liability of $4.3 million as of December 31, 2020.

Commitments and Contingent Liabilities	11. Commitments and Contingent Liabilities ​ 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 June 30, 2021, 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 lease land and facilities, including certain dealerships and office space. 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. Refer to the disclosures provided in Note 3 for further description of our leases. ​ 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. ​ Our floor plan credit agreements with Mercedes Benz Financial Services Australia and Mercedes Benz Financial Services New Zealand (“MBA”) provide us revolving loans for the acquisition of commercial vehicles for distribution to our retail network. These facilities include a commitment to repurchase dealer vehicles in the event the dealer’s floor plan agreement with MBA is terminated. ​ We have $55.9 million of letters of credit outstanding as of June 30, 2021, and have posted $21.8 million of surety bonds in the ordinary course of business.

Segment Information
Segment Information	​ 14. Segment Information ​ Our operations are organized by management into operating segments by line of business and geography. We have determined that we have four reportable segments as defined in generally accepted accounting principles for segment reporting: (i) Retail Automotive, consisting of our retail automotive dealership operations; (ii) Retail Commercial Truck, consisting of our retail commercial truck dealership operations in the U.S. and Canada; (iii) Other, consisting of our commercial vehicle and power systems distribution operations; and (iv) Non-Automotive Investments, consisting of our equity method investments in non-automotive operations which includes our investment in PTS. The Retail Automotive reportable segment includes all automotive dealerships and all departments relevant to the operation of the dealerships and our retail automotive joint ventures. The individual dealership operations included in the Retail Automotive reportable segment represent six operating segments: Eastern, Central, and Western United States, Used Vehicle SuperCenters United States, International, and Used Vehicle SuperCenters International. These 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/or 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 accompanying 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 (“U.S. GAAP”) have been condensed or omitted pursuant to the SEC rules and regulations. The information presented as of June 30, 2021, and December 31, 2020, and for the three and six month periods ended June 30, 2021, and 2020 is unaudited but includes all adjustments which our management believes to be necessary for the fair presentation of results for the periods presented. 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, 2020, which are included as part of our Annual Report on Form 10-K.
Estimates	Estimates ​ The preparation of financial statements in accordance 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 our fixed rate debt is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2021 ​ December 31, 2020 ​ Carrying Value Fair Value Carrying Value Fair Value 3.50% senior subordinated notes due 2025 ​ ​ 544.0 ​ ​ 564.1 ​ ​ 543.2 ​ $ 554.6 ​ 3.75% senior subordinated notes due 2029 ​ ​ 493.9 ​ ​ 498.2 ​ ​ — ​ ​ — ​ Mortgage facilities ​ 398.9 ​ 406.5 ​ 458.1 ​ 474.7 ​ ​ During the second quarter of 2021, we issued $500 million in aggregate principal amount of 3.75% senior subordinated notes due 2029, the proceeds of which were used to redeem our $500 million in aggregate principal amount of 5.50% senior subordinated notes due 2026 on June 24, 2021. Refer to Note 9 “Long-Term Debt” for further discussion.
Discontinued Operations	Discontinued Operations ​ We had no entities newly classified as held for sale during the six months ended June 30, 2021, or 2020 that met the criteria to be classified as discontinued operations.
Disposals	Disposals ​ During the six months ended June 30, 2021, we disposed of one retail automotive franchise. The results of operations for this business are included within continuing operations for the three and six months ended June 30, 2021, and 2020 as this franchise did not meet the criteria to be classified as held for sale and treated as discontinued operations.
Income Taxes	Income Taxes Tax regulations may require items to be included in our tax return at different times than when those items are reflected in our financial statements. Some of the differences are permanent, such as expenses that are not deductible on our tax return, and some are temporary differences, such as the timing of depreciation expense. Temporary differences create deferred tax assets and liabilities. Deferred tax assets generally represent items that will be used as a tax deduction or credit in our tax return in future years which we have already recorded in our financial statements. Deferred tax liabilities generally represent deductions taken on our tax return that have not yet been recognized as an expense in our financial statements. We establish valuation allowances for our deferred tax assets if the amount of expected future taxable income is not more likely than not to allow for the use of the deduction or credit. ​
Recent Accounting Pronouncements	Recent Accounting Pronouncements ​ Reference Rate Reform ​ In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This ASU provides optional guidance for a limited time to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. Additionally, entities can elect to continue applying hedge accounting for hedging relationships affected by reference rate reform if certain conditions are met. In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848): Scope.” This ASU refines the scope of ASC 848 and clarifies some of its guidance as part of the Board’s monitoring of global reference rate reform activities. The ASU permits entities to elect certain optional expedients and exceptions when accounting for derivative contracts and certain hedging relationships affected by changes in the interest rates used for discounting cash flows, for computing variation margin settlements, and for calculating price alignment interest in connection with reference rate reform activities. These new standards were effective upon issuance and generally can be applied to applicable contract modifications through December 31, 2022. Our senior secured revolving credit facilities in the U.S. and U.K. and many of our floorplan arrangements utilize LIBOR as a benchmark for calculating the applicable interest rate. We are currently evaluating the impact of the transition from LIBOR to alternative reference interest rates. We cannot predict the effect of the potential changes to or elimination of LIBOR, the establishment and use of alternative rates or benchmarks, and the corresponding effects on our cost of capital but do not expect a significant impact on our consolidated financial position, results of operations, and cash flows. ​ Disclosures for Business Acquisitions, Dispositions, and Significant Subsidiaries ​ On May 20, 2020, the SEC issued a final rule that amends the financial statement requirements for acquisitions and dispositions of businesses, including the determinations of whether a subsidiary or an acquired or disposed business is significant. The significance test rule changes to SEC Regulation S-X, Rule 3-09 impact our disclosure requirements for equity method investments, including our investment in Penske Transportation Solutions (“PTS”) as it relates to providing audited financial statements and summarized financial statement information in our footnotes disclosures. The rule is effective January 1, 2021, but earlier compliance is permitted. The Company early adopted this rule in the fourth quarter of 2020.
