1. Description of Business and Summary of Significant Accounting Policies

Organization and Business - Sonic Automotive, Inc. (“Sonic” or the “Company”) is one of the largest automotive retailers in the United States (as measured by total revenue). As of December 31, 2017, Sonic operated 114 new vehicle franchises in 13 states (representing 23 different brands of cars and light trucks), 18 collision repair centers and nine pre-owned stores. As a result of the way management operates the business, Sonic had two operating segments as of December 31, 2017: (1) the Franchised Dealerships Segment and (2) the Pre-Owned Stores Segment. For management and operational reporting purposes, Sonic groups certain franchises together that share management and inventory (principally used vehicles) into “stores.” As of December 31, 2017, Sonic operated 103 stores in the Franchised Dealerships Segment and nine stores in the Pre-Owned Stores Segment.

The Franchised Dealerships Segment provides comprehensive services, including (1) sales of both new and used cars and light trucks; (2) sales of replacement parts and performance of vehicle maintenance, manufacturer warranty repairs, and paint and collision repair services (collectively, “Fixed Operations”); and (3) arrangement of extended warranties, service contracts, financing, insurance and other aftermarket products (collectively, “F&I”) for its customers. The Pre-Owned Stores Segment provides the same services (excluding new vehicle sales and manufacturer warranty repairs) in stand-alone pre-owned vehicle specialty retail locations and includes Sonic’s EchoPark stores. Sonic’s pre-owned stores business operates independently from its franchised dealerships business.

Principles of Consolidation - All of Sonic’s dealership and non-dealership subsidiaries are wholly owned and consolidated in the accompanying consolidated financial statements except for one 50%-owned dealership that is accounted for under the equity method. All material intercompany balances and transactions have been eliminated in the accompanying consolidated financial statements.

Recent Accounting Pronouncements - In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2014-09 as well as several subsequent amendments to amend the accounting guidance on revenue recognition. The amendments to the standard are intended to provide a more robust framework for addressing revenue issues, improve comparability of revenue recognition practices and improve disclosure requirements. The amendments to this standard must be applied using either of the following transition methods: (1) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or (2) a modified retrospective approach with the cumulative effect of initially adopting the standard recognized at the date of adoption (which requires additional footnote disclosures). These amendments are effective for reporting periods beginning after December 15, 2017. Earlier application is permitted only as of reporting periods beginning after December 15, 2016. Sonic adopted this ASU effective January 1, 2018 using the modified retrospective transition approach applied to contracts not completed as of the date of adoption, with no restatement of comparative periods and a cumulative effect adjustment to retained earnings recognized as of the date of adoption.

Under the new standard, revenue is recognized when a customer obtains control of promised goods or services and in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. The principles apply a five-step model that includes: (1) identifying the contract(s) with the customer; (2) identifying the performance obligation(s) in the contract; (3) determining the transaction price; (4) allocating the transaction price to the performance obligation(s) in the contract; and (5) recognizing revenue as the performance obligation(s) are satisfied. The standard also requires disclosure of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

During the implementation process, management evaluated its established business processes, revenue transaction streams and accounting policies, and generally expects similar performance obligations to result under the new standard as compared with prior U.S. generally accepted accounting principles and does not expect the adoption of this standard to have a material impact on its consolidated financial statements, revenue recognition practices, accounting policies or internal controls. Management identified its material revenue streams to be (1) the sale of new vehicles; (2) the sale of used vehicles to retail customers; (3) the sale of used vehicles at wholesale auction; (4) arrangement of vehicle financing and the sale of service and other insurance contracts; and (5) the performance of vehicle maintenance and repair services and sale of related parts and accessories. As a result of its analysis during the implementation process, management expects the amounts and timing of revenue recognition to generally remain the same, with the exception of the timing of revenue recognition related to: (1) service and collision repair orders that are incomplete as of a reporting date (“work in process”) and (2) certain retrospective finance and insurance revenue earned in periods subsequent to the completion of the initial performance obligation (“F&I retro revenue”), both of which are subject to accelerated recognition under the new standard. While management is finalizing the cumulative effect adjustment to retained earnings, the expected impact on Sonic’s consolidated financial statements as a result of the changes in revenue recognition practices described above is not expected to be material. Management estimates that the adoption of the new revenue recognition standard will result in a net, after-tax cumulative effect adjustment to increase retained earnings of approximately $3.0 million as of January 1, 2018.

In February 2016, the FASB issued ASU 2016-02 to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The amendments in this ASU require that leases are classified as either finance or operating leases, a right-of-use asset and lease liability is recognized in the statement of financial position, and repayments are classified within operating activities in the statement of cash flows. The amendments in this ASU are to be applied using a modified retrospective approach and are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 (early adoption is permitted). Sonic plans to adopt this ASU effective January 1, 2019. While management is still evaluating the impact of adopting the provisions of this ASU, management expects that upon adoption of this ASU, the presentation of certain items in Sonic’s consolidated financial position, cash flows and other disclosures will be materially impacted, primarily due to the recognition of a right-of-use asset and an associated liability and a change in the timing and classification of certain items in Sonic’s results of operations as a result of the derecognition of the lease liability.

In March 2016, the FASB issued ASU 2016-09 to simplify several aspects of the accounting for share-based payment transactions. For public companies, this ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016 (early adoption is permitted). Sonic adopted this ASU effective January 1, 2017. Upon adoption of this ASU, interim period and annual income tax expense is affected by stock option exercises and restricted stock and restricted stock unit vesting activity, potentially creating volatility in Sonic’s effective income tax rate from period to period. See the heading “Income Taxes” below for further discussion of the impact of the adoption of this ASU on Sonic’s effective income tax rate for 2017.

In January 2017, the FASB issued ASU 2017-04 to simplify the subsequent measurement of goodwill by eliminating step two from the goodwill impairment test. For public companies, this ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019 (early adoption is permitted for impairment testing dates after January 1, 2017). Sonic adopted this ASU prior to its impairment test as of October 1, 2017.

In August 2017, the FASB issued ASU 2017-12 which amends the hedge accounting recognition and presentation requirements in Accounting Standards Codification (“ASC”) 815. This ASU expands and refines hedge accounting for both nonfinancial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. It also includes certain targeted improvements to simplify the application of current guidance related to hedge accounting. For public companies, this ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 (early adoption is permitted). Sonic is currently in the process of evaluating the effects of this pronouncement on its consolidated financial statements.

Reclassifications - Prior to Sonic’s adoption of ASU 2014-08 beginning with its Quarterly Report on Form 10-Q for the period ended June 30, 2014, individual dealership franchises sold, terminated or classified as held for sale were reported as discontinued operations. The results of operations of these dealership franchises sold or terminated prior to March 31, 2014 are reported as discontinued operations for all periods presented. Dealership franchises sold on or after to March 31, 2014 have not been reclassified to discontinued operations since they did not meet the criteria in ASU 2014-08. If, in future periods, Sonic determines that a dealership franchise should be reclassified from continuing operations to discontinued operations, previously reported consolidated statements of income will be reclassified in order to reflect the most recent classification.

Use of Estimates - The preparation of financial statements in conformity with U.S. GAAP requires Sonic’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the accompanying consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates, particularly related to allowance for credit loss, realization of inventory, intangible asset and deferred tax asset values, reserves for tax contingencies, legal matters, reserves for future commission revenue to be returned to the third-party provider for early termination of customer contracts (“chargebacks”), results reported as continuing and discontinued operations, insurance reserves, lease exit accruals and certain accrued expenses.

Cash and Cash Equivalents - Sonic classifies cash and all highly liquid investments with a maturity of three months or less at the date of purchase, including short-term time deposits and government agency and corporate obligations, as cash and cash equivalents. In the event that Sonic is in a book overdraft cash position as of a reporting date, the book overdraft position is reclassified from cash and cash equivalents to trade accounts payable in the accompanying consolidated balance sheets and is reflected as activity in trade accounts payable and other liabilities in the accompanying consolidated statements of cash flows. Sonic was in a book overdraft position in an amount of approximately $6.9 million and $8.0 million, as of December 31, 2017 and 2016, respectively.

Revenue Recognition - Sonic records revenue when vehicles are delivered to customers, when vehicle service work is performed and when parts are delivered. Conditions for completing a sale include having an agreement with the customer, including pricing, and the sales price must be reasonably expected to be collected. See the previous heading “Recent Accounting Pronouncements” for discussion of changes to revenue recognition effective January 1, 2018 upon adoption of ASC 2014-09.

Sonic arranges financing for customers through various financial institutions and receives a commission from the financial institution either in a flat fee amount or in an amount equal to the difference between the interest rates charged to customers and the predetermined interest rates set by the financial institution. Sonic also receives commissions from the sale of various insurance contracts and non-recourse third-party extended service contracts to customers. Sonic may be assessed a chargeback fee in the event of early cancellation of a loan or insurance contract by the customer. Finance and insurance commission revenue is recorded net of estimated chargebacks at the time the related contract is placed with the financial institution.

Sonic also receives commissions from the sale of non-recourse third-party extended service contracts to customers. Under these contracts, the applicable manufacturer or third-party warranty company is directly liable for all warranties provided within the contract. Commission revenue from the sale of these third-party extended service contracts is recorded net of estimated chargebacks at the time of sale.

As of December 31, 2017 and 2016, the amounts recorded as allowances for finance, insurance and service contract commission chargeback reserves were $20.9 million and $19.2 million, respectively, and were classified as other accrued liabilities and other long-term liabilities in the accompanying consolidated balance sheets.

Floor Plan Assistance - Sonic receives floor plan assistance payments from certain manufacturers. This assistance reduces the carrying value of Sonic’s new vehicle inventory and is recognized as a reduction of cost of sales at the time the vehicle is sold. Amounts recognized as a reduction of cost of sales were $45.3 million, $45.0 million and $42.1 million for 2017, 2016 and 2015, respectively.

Contracts in Transit - Contracts in transit represent customer finance contracts evidencing loan agreements or lease agreements between Sonic, as creditor, and the customer, as borrower, to acquire or lease a vehicle in situations where a third-party finance source has given Sonic initial, non-binding approval to assume Sonic’s position as creditor. Funding and final approval from the finance source is provided upon the finance source’s review of the loan or lease agreement and related documentation executed by the customer at the dealership. These finance contracts are typically funded within 10 days of the initial approval of the finance transaction given by the third-party finance source. The finance source is not contractually obligated to make the loan or lease to the customer until it gives its final approval and funds the transaction, and until such final approval is given, the contracts in transit represent amounts due from the customer to Sonic. Contracts in transit are included in receivables, net on the accompanying consolidated balance sheets and totaled $267.6 million and $236.4 million at December 31, 2017 and 2016, respectively.

Accounts Receivable - In addition to contracts in transit, Sonic’s accounts receivable primarily consists of amounts due from the manufacturers for repair services performed on vehicles with a remaining factory warranty and amounts due from third parties from the sale of parts. Sonic evaluates receivables for collectability based on the age of the receivable, the credit history of the customer and past collection experience. The allowance for doubtful accounts receivable was not significant at December 31, 2017 and 2016.

Inventories - Inventories of new vehicles, recorded net of manufacturer credits, and used vehicles, including demonstrators, are stated at the lower of specific cost or market. Inventories of parts and accessories are accounted for using the “first-in, first-out” (“FIFO”) method of inventory accounting and are stated at the lower of FIFO cost or market. Other inventories are primarily service loaner vehicles and, to a lesser extent, vehicle chassis, other supplies and capitalized customer work-in-progress (open customer vehicle repair orders). Other inventories are stated at the lower of specific cost (depreciated cost for service loaner vehicles) or market.

Sonic assesses the valuation of all its vehicle and parts inventories and maintains a reserve where the cost basis exceeds the fair market value. In making this assessment for new vehicles, used vehicles, service loaners and parts inventory, Sonic considers recent internal and external market data and the age of the vehicles to estimate the inventory’s fair market value. The risk with vehicle inventory is minimized by the fact that vehicles can be transferred within Sonic’s network of dealerships. The risk with parts inventories is minimized by the fact that excess or obsolete parts can also be transferred within Sonic’s network of dealerships or can usually be returned to the manufacturer. Recorded inventory reserves were not significant at December 31, 2017 and 2016.

Property and Equipment - Property and equipment are stated at cost. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets. Sonic amortizes leasehold improvements over the shorter of the estimated useful life or the remaining lease life. This lease life includes renewal options if a renewal has been determined to be reasonably assured. The range of estimated useful lives is as follows:

Leasehold and land improvements		10-30 years
Buildings		10-30 years
Parts and service equipment		7-10 years
Office equipment and fixtures		3-10 years
Company vehicles		3-5 years

Sonic reviews the carrying value of property and equipment and other long-term assets (other than goodwill and franchise assets) for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If such an indication is present, Sonic compares the carrying amount of the asset to the estimated undiscounted cash flows related to that asset. Sonic concludes that an asset is impaired if the sum of such expected future cash flows is less than the carrying amount of the related asset. If Sonic determines an asset is impaired, the impairment loss would be the amount by which the carrying amount of the related asset exceeds its fair value. The fair value of the asset would be determined based on the quoted market prices, if available. If quoted market prices are not available, Sonic determines fair value by using a discounted cash flow model. See Note 4, “Property and Equipment,” for a discussion of impairment charges.

Derivative Instruments and Hedging Activities - Sonic utilizes derivative financial instruments for the purpose of hedging the risks of certain identifiable and anticipated transactions. Commonly, the types of risks being hedged are those relating to the variability of cash flows caused by fluctuations in interest rates. Sonic documents its risk management strategy and hedge effectiveness at the inception of and during the term of each hedge. As of December 31, 2017, Sonic utilized interest rate cash flow swap agreements to effectively convert a portion of its LIBOR-based variable rate debt to a fixed rate. In addition, Sonic has interest rate cap agreements to limit its exposure to increases in LIBOR rates above certain levels. See Note 6, “Long-Term Debt,” for further discussion of derivative instruments and hedging activities.

Goodwill - Goodwill is recognized to the extent that the purchase price of the acquisition exceeds the estimated fair value of the net assets acquired, including other identifiable intangible assets. In accordance with “Intangibles - Goodwill and Other” in the ASC, goodwill is tested for impairment at least annually, or more frequently when events or circumstances indicate that impairment might have occurred. The ASC also states that if an entity determines, based on an assessment of certain qualitative factors, that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then a quantitative goodwill impairment test is unnecessary. For purposes of goodwill impairment testing, Sonic has two reporting units, which consist of: (1) its traditional franchised dealerships and (2) its pre-owned stores. The carrying value of Sonic’s goodwill totaled approximately $525.8 million at December 31, 2017, $465.8 million of which is related to its franchised dealerships reporting unit and $60.0 million of which is related to its pre-owned stores reporting unit. As the $60.0 million of goodwill carrying value related to the pre-owned stores reporting unit was acquired immediately preceding the testing date, Sonic evaluated impairment on a qualitative basis and determined there was no indication of impairment. For the franchised dealerships reporting unit, Sonic utilized the Market Price (“MP”) method to estimate its enterprise value as of October 1, 2017. The significant inputs in the MP method include debt value, stock price and control premium.

In evaluating goodwill for impairment, if the fair value of a reporting unit is less than its carrying value, the difference would represent the amount of required goodwill impairment. To the extent the reporting unit’s earnings decline significantly or there are changes in one or more of these inputs that would result in lower valuation results, it could cause the carrying value of the reporting unit to exceed its fair value and thus require Sonic to record goodwill impairment.

Based on the results of Sonic’s quantitative test as of October 1, 2017, its franchised dealerships reporting unit’s fair value exceeded its carrying value. As a result, Sonic was not required to record goodwill impairment for either of its reporting units. See Note 5, “Intangible Assets and Goodwill,” for further discussion of goodwill.

Other Intangible Assets - The principal identifiable intangible assets other than goodwill acquired in an acquisition are rights under franchise or dealer agreements with manufacturers. Sonic classifies franchise and dealer agreements as indefinite lived intangible assets as it has been Sonic’s experience that renewals have occurred without substantial cost or material modifications to the underlying agreements. As such, Sonic believes that its franchise and dealer agreements will contribute to cash flows for an indefinite period, therefore the carrying amount of franchise rights is not amortized. Franchise and dealer agreements acquired on or after July 1, 2001 have been included in other intangible assets, net on the accompanying consolidated balance sheets. Prior to July 1, 2001, franchise and dealer agreements were recorded and amortized as part of goodwill and remain as part of goodwill on the accompanying consolidated balance sheets. Other intangible assets acquired in acquisitions include favorable lease agreements with definite lives which are amortized on a straight-line basis over the remaining lease term. In accordance with “Intangibles - Goodwill and Other” in the ASC, Sonic evaluates other intangible assets for impairment annually (as of October 1) or more frequently if indicators of impairment exist.

Sonic utilized a discounted cash flow (“DCF”) model to estimate the fair value of the franchise assets for each of its franchises with recorded franchise assets. The significant assumptions in Sonic’s DCF model include projected revenue, weighted average cost of capital (and estimates in the weighted average cost of capital inputs) and residual growth rates. In projecting the franchises’ revenue and growth rates, Sonic develops many assumptions which may include, but are not limited to, revenue growth, internal revenue enhancement initiatives, cost control initiatives, internal investment programs (such as training, technology and infrastructure) and inventory floor plan borrowing rates. Sonic’s expectation of revenue growth is in part driven by its estimates of new vehicle industry sales volume in future periods. Sonic believes the historic and projected industry sales volume is a good indicator of growth or contraction in the retail automotive industry.

Based on the October 1, 2017 impairment test, Sonic determined that the fair value of the franchise assets exceeded the carrying value of the franchise assets for all but four of its franchises, resulting in a franchise asset impairment charge of $3.6 million during 2017, recorded in impairment charges in the accompanying consolidated statements of income. See Note 5, “Intangible Assets and Goodwill,” for further discussion of franchise and dealer agreements.

In evaluating its definite life favorable lease assets for impairment, Sonic considered whether the leased asset was being utilized by the dealership and if the dealership operating activities could recover the value of the recorded favorable lease asset. Sonic evaluated its favorable lease assets for impairment as of October 1, 2017 and determined that no impairment was required.

Insurance Reserves - Sonic has various self-insured and high deductible casualty and other insurance programs which require the Company to make estimates in determining the ultimate liability it may incur for claims arising under these programs. These insurance reserves are estimated by management using actuarial evaluations based on historical claims experience, claims processing procedures, medical cost trends and, in certain cases, a discount factor. As of December 31, 2017 and 2016, Sonic had $22.0 million and $22.7 million, respectively, reserved for such programs.

Lease Exit Accruals - The majority of Sonic’s dealership properties are leased under long-term operating lease arrangements. When situations arise where the leased properties are no longer utilized in operations, Sonic records accruals for the present value of the lease payments, net of estimated sublease rentals, for the remaining life of the operating leases and other accruals necessary to satisfy the lease commitment to the landlord. These situations could include the relocation of an existing facility or the sale of a dealership when the buyer will not be subleasing the property for either the remaining term of the lease or for an amount of rent equal to Sonic’s obligation under the lease, or situations in which a store is closed as a result of the associated franchise being terminated by the manufacturer or Sonic and no other operations continue on the leased property. See Note 12, “Commitments and Contingencies,” for further discussion.

Income Taxes - Income taxes are provided for the tax effects of transactions reported in the accompanying consolidated financial statements and consist of taxes currently due plus deferred taxes. Deferred taxes are provided at enacted tax rates for the tax effects of carryforward items and temporary differences between the tax basis of assets and liabilities and their reported amounts. As a matter of course, the Company is regularly audited by various taxing authorities and, from time to time, these audits result in proposed assessments where the ultimate resolution may result in the Company owing additional taxes. Sonic’s management believes that the Company’s tax positions comply, in all material respects, with applicable tax law and that the Company has adequately provided for any reasonably foreseeable outcome related to these matters.

From time to time, Sonic engages in transactions in which the tax consequences may be subject to uncertainty. Significant judgment is required in assessing and estimating the tax consequences of these transactions. Sonic determines whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, Sonic presumes that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information. A tax position that does not meet the more-likely-than-not recognition threshold is measured to determine the amount of benefit to be recognized in the financial statements. The tax position is measured at the largest amount of benefit that is likely to be realized upon ultimate settlement. Sonic adjusts its estimates periodically because of ongoing examinations by and settlements with the various taxing authorities, as well as changes in tax laws, regulations and precedent. See Note 7, “Income Taxes,” for further discussion of Sonic’s uncertain tax positions.

Concentrations of Credit and Business Risk - Financial instruments that potentially subject Sonic to concentrations of credit risk consist principally of cash on deposit with financial institutions. At times, amounts invested with financial institutions exceed Federal Deposit Insurance Corporation insurance limits. Concentrations of credit risk with respect to receivables are limited primarily to receivables from automobile manufacturers, totaling approximately $102.5 million and $92.8 million at December 31, 2017 and 2016, respectively, and receivables from financial institutions (which include manufacturer-affiliated finance companies and commercial banks), totaling approximately $299.6 million and $265.3 million at December 31, 2017 and 2016, respectively. Credit risk arising from trade receivables from commercial customers is reduced by the large number of customers comprising the trade receivables balances.

Sonic participates in a program with two of its manufacturer-affiliated finance companies and one commercial bank wherein Sonic maintains a deposit balance with the lender that earns floor plan interest rebates based on the agreed upon rate. This deposit balance is not designated as a pre-payment of notes payable - floor plan, nor is it Sonic’s intent to use this amount to offset principal amounts owed under notes payable - floor plan in the future, although Sonic has the right and ability to do so. The deposit balance of $3.0 million and $10.0 million as of December 31, 2017 and 2016, respectively, is classified in other current assets in the accompanying consolidated balance sheets, because there are restrictions on Sonic’s availability to withdraw these funds under certain circumstances. Changes in this deposit balance are classified as changes in other assets in the cash flows from operating activities section of the accompanying consolidated statements of cash flows. The interest rebate as a result of this deposit balance is classified as a reduction in interest expense, floor plan in the accompanying consolidated statements of income. In 2017, 2016 and 2015, the reduction in interest expense, floor plan was approximately $0.5 million, $0.6 million and $1.5 million, respectively.

Sonic is subject to a concentration of risk in the event of financial distress or other adverse events related to any of the automobile manufacturers whose franchised dealerships are included in Sonic’s brand portfolio. Sonic purchases its new vehicle inventory from various automobile manufacturers at the prevailing prices available to all franchised dealerships. In addition, Sonic finances a substantial portion of its new vehicle inventory with manufacturer-affiliated finance companies. Sonic’s results of operations could be adversely affected by the manufacturers’ inability to supply Sonic’s dealerships with an adequate supply of new vehicle inventory and related floor plan financing. Sonic also has concentrations of risk related to geographic markets in which its dealerships operate. Changes in overall economic, retail automotive or regulatory environments in one or more of these markets could adversely impact Sonic’s results of operations.

Financial Instruments and Market Risks - As of December 31, 2017 and 2016, the fair values of Sonic’s financial instruments including receivables, notes receivable from finance contracts, notes payable - floor plan, trade accounts payable, borrowings under the revolving credit facilities and certain mortgage notes approximated their carrying values due either to length of maturity or existence of variable interest rates that approximate prevailing market rates. See Note 11, “Fair Value Measurements,” for further discussion of the fair value and carrying value of Sonic’s fixed rate long-term debt and other financial instruments.

Sonic has variable rate notes payable - floor plan, revolving credit facilities and other variable rate notes that expose Sonic to risks caused by fluctuations in the underlying interest rates. The counterparties to Sonic’s interest rate swap and interest rate cap agreements are large financial institutions. Sonic could be exposed to loss in the event of non-performance by any of these counterparties. See further discussion in Note 6, “Long-Term Debt.”

Advertising - Sonic expenses advertising costs in the period incurred, net of earned cooperative manufacturer credits that represent reimbursements for specific, identifiable and incremental advertising costs. Advertising expense amounted to approximately $61.6 million, $61.7 million and $61.6 million for 2017, 2016 and 2015, respectively, and is classified as selling, general and administrative expenses in the accompanying consolidated statements of income.

Sonic has cooperative advertising reimbursement agreements with certain automobile manufacturers it represents. These agreements require Sonic to provide the manufacturer with support for qualified, actual advertising expenditures in order to receive reimbursement under the agreements. It is uncertain whether or not Sonic would maintain the same level of advertising expenditures if these manufacturers discontinued their cooperative programs. Cooperative manufacturer credits classified as an offset to advertising expenses were approximately $26.0 million, $26.2 million and $24.2 million for 2017, 2016 and 2015, respectively.

Segment Information - Sonic has determined it has two reporting segments: (1) the Franchised Dealerships Segment and (2) the Pre-Owned Stores Segment, for purposes of reporting financial condition and results of operations. The Franchised Dealerships Segment is comprised of retail automotive franchises that sell new vehicles and buy and sell used vehicles, sell replacement parts, perform vehicle repair and maintenance services, and arrange finance and insurance products. The Pre-Owned Stores Segment is comprised of stand-alone pre-owned vehicle specialty retail locations that provide customers an opportunity to search, buy, service, finance and sell pre-owned vehicles.
