Summary of Significant Accounting Policies |
Summary of significant accounting policies | NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ​ Nature of business: O’Reilly Automotive, Inc. and Subsidiaries, collectively, “O’Reilly” or the “Company,” is a specialty retailer and supplier of automotive aftermarket parts. The Company’s stores carry an extensive product line, including new and remanufactured automotive hard parts, maintenance items and various automotive accessories. As of December 31, 2020, the Company owned and operated 5,594 stores in 47 U.S. states and 22 stores in Mexico, servicing both do-it-yourself (“DIY”) and the professional service provider customers. The Company’s robust distribution system provides stores with same-day or overnight access to an extensive inventory of hard-to-find items not typically stocked in the stores of other auto parts retailers. ​ Segment reporting: The Company is managed and operated by a single management Team reporting to the chief operating decision maker. The Company’s stores have similar characteristics, including the nature of the products and services, the type and class of customers and the methods used to distribute products and provide service to its customers and, as a whole, make up a single operating segment. The Company does not regularly prepare for review by the chief operating decision maker discrete financial information with respect to product lines, types of customers or geographic locations and as such has one reportable segment. ​ Principles of consolidation: The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation. ​ Use of estimates: The preparation of the consolidated financial statements, in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”), requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates. ​ Cash equivalents: Cash equivalents include investments with maturities of 90 days or less on the date of purchase. ​ Foreign Currency: The Company accounts for its Mexican operations using the local market currency, the Mexican peso, and converts its financial statements compiled for these operations from the Mexican peso to U.S. dollars. The cumulative gain or loss on currency translation is included as a component of “Accumulated other comprehensive income” on the accompanying Consolidated Balance Sheets. See Note 11 for further information concerning the Company’s accumulated other comprehensive income. ​ Accounts receivable: The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of the Company’s customers to make required payments. The Company considers the following factors when determining if collection is reasonably assured: customer creditworthiness, past transaction history with the customer, current expectations of future economic and industry trends, changes in customer payment terms and management’s expectations. Allowances for doubtful accounts are determined based on historical experience and an evaluation of the current composition of accounts receivable. ​ The Company grants credit to certain professional service provider and jobber customers who meet the Company’s pre-established credit requirements. Concentrations of credit risk with respect to these receivables are limited because the Company’s customer base consists of a large number of small customers, spreading the credit risk across a broad base regarded as a single class of financing receivable by the Company. The Company also controls this credit risk through credit approvals, credit limits and accounts receivable and credit monitoring procedures. Generally, the Company does not require security when credit is granted to customers. Credit is granted to customers on a short-term basis, consisting primarily of daily, weekly or monthly accounts. Credit losses are provided for in the Company’s consolidated financial statements and have consistently been within management’s expectations. ​ Amounts due to the Company from its Team Members are included in “Accounts receivable” on the accompanying Consolidated Balance Sheets. These amounts consist primarily of purchases of merchandise on Team Member accounts. Accounts receivable due from Team Members was approximately $0.9 million as of December 31, 2020 and 2019, respectively. ​ Amounts receivable from suppliers: The Company receives concessions from its suppliers through a variety of programs and arrangements, including allowances for new stores and warranties, volume purchase rebates and co-operative advertising. Co-operative advertising allowances that are incremental to the Company’s advertising program, specific to a product or event and identifiable for accounting purposes are reported as a reduction of advertising expense in the period in which the advertising occurred. All other supplier concessions are recognized as a reduction to the cost of sales. Amounts receivable from suppliers also include amounts due to the Company for changeover merchandise and product returns. The Company regularly reviews supplier receivables for collectability and assesses the need for a reserve for uncollectable amounts based on an evaluation of the Company’s suppliers’ financial positions and corresponding abilities to meet financial obligations. Management does not believe there is a reasonable likelihood that the Company will be unable to collect the amounts receivable from suppliers and the Company did not record a reserve for uncollectable amounts from suppliers in the consolidated financial statements as of December 31, 2020 or 2019. ​ Inventory: Inventory, which consists of automotive hard parts, maintenance items, accessories and tools, is stated at the lower of cost or market. Inventory also includes capitalized costs related to procurement, warehousing and distribution centers (“DC”s). Cost has been determined using the last-in, first-out (“LIFO”) method, which more accurately matches costs with related revenues. Over time, as the Company’s merchandise inventory purchases have increased, the Company negotiated improved acquisition costs from its suppliers and the corresponding price deflation exhausted the Company’s LIFO reserve balance. The Company’s policy is to not write up the value of its inventory in excess of its replacement cost, and accordingly, the Company’s merchandise inventory has been effectively recorded at replacement cost since December 31, 2013. The replacement cost of inventory was $3.67 billion and $3.47 billion as of December 31, 2020 and 2019, respectively. LIFO costs exceeded replacement costs by $55.8 million and $31.0 million at December 31, 2020 and 2019, respectively. ​ Fair value of financial instruments: The Company uses the fair value hierarchy, which prioritizes the inputs used to measure the fair value of certain of its financial instruments. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The Company uses the income and market approaches to determine the fair value of its assets and liabilities. The three levels of the fair value hierarchy are set forth below:
| ● | Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.
| ● | Level 2 – Inputs other than quoted prices in active markets included within Level 1 that are observable for the asset or liability, either directly or indirectly.
| ● | Level 3 – Unobservable inputs for the asset or liability.
​ See Note 3 for further information concerning the Company’s financial and non-financial assets and liabilities measured at fair value on a recurring and non-recurring basis. ​ Property and equipment: Property and equipment are carried at cost. Depreciation is calculated using the straight-line method, generally over the estimated useful lives of the assets. Leasehold improvements are amortized over the lesser of the lease term or the estimated economic life of the assets. The lease term includes renewal options determined by management at lease inception, for which failure to execute renewal options would result in a substantial economic penalty to the Company. Maintenance and repairs are charged to expense as incurred. Upon retirement or sale, the cost and accumulated depreciation are eliminated and the gain or loss, if any, is recognized in the Company’s Consolidated Statements of Income. The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. See Note 5 for further information concerning the Company’s property and equipment. ​ Goodwill and other intangibles: The accompanying Consolidated Balance Sheets at December 31, 2020 and 2019, include goodwill and other intangible assets recorded as the result of acquisitions. The Company operates a single reporting unit and evaluates goodwill and indefinite-lived intangibles for impairment annually during the fourth quarter, or when events or changes in circumstances indicate the carrying value of these assets might exceed their current fair values. Beginning in 2019, the goodwill impairment test includes a qualitative assessment. The Company’s qualitative assessment found no evidence to suggest it is more likely than not that its fair value is less than its carrying amount, including goodwill, as of December 31, 2020 and 2019. As such, no goodwill impairment adjustment was required as of December 31, 2020 and 2019. Finite-lived intangibles are carried at amortized cost and amortization is calculated using the straight-line method, generally over the estimated useful lives of the intangibles. See Note 7 for further information concerning the Company’s goodwill and other intangibles. ​ Leases: The Company leases certain office space, retail stores, distribution centers and equipment under long-term, non-cancelable operating leases. Lease components are not accounted for separately from nonlease components. Leases generally include renewal options and some include options to purchase, provisions for percentage rent based on sales and/or incremental step increase provisions. The exercise of renewal options is typically at the Company’s sole discretion and all operating lease expense is recognized on a straight-line basis over the lease term. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company rents or subleases certain surplus real estate to third parties. Right-of-use assets and corresponding operating lease liabilities are recognized for all leases with an initial term greater than 12 months. See Note 6 for further information concerning the Company’s operating leases. ​ Impairment of long-lived assets: The Company reviews its long-lived assets, including its right-of-use assets, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. When such an event occurs, the Company compares the sum of the undiscounted expected future cash flows of the asset (asset group) with the carrying amounts of the asset. If the undiscounted expected future cash flows are less than the carrying value of the assets, the Company measures the amount of impairment loss as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The Company has not historically recorded any material impairment charges to its long-lived assets. During the year ended December 31, 2020, the Company recorded a charge of $3.4 million, related to the write-down on surplus land and buildings that exceeded market value, and $1.9 million and $11.4 million, during the years ended December 31, 2019 and 2018, respectively, related to its long-lived assets, primarily due to the disposal of certain software projects that were no longer expected to provide a long-term benefit. ​ Valuation of investments: The Company has an unsecured obligation to pay, in the future, the value of deferred compensation and a Company match relating to employee participation in the Company’s nonqualified deferred compensation plan (the “Deferred Compensation Plan”). The future obligation is adjusted to reflect the performance, whether positive or negative, of selected investment measurement options, chosen by each participant. The Company invests in various marketable securities with the intention of selling these securities to fulfill its future obligations under the Deferred Compensation Plan. The investments in this plan were stated at fair value based on quoted market prices, were accounted for as trading securities and were included in “Other assets, net” on the accompanying Consolidated Balance Sheets as of December 31, 2020 and 2019. See Note 3 for further information concerning the fair value measurements of the Company’s marketable securities. See Note 13 for further information concerning the Company’s benefit plans. ​ Variable Interest Entities: The Company invests in certain tax credit funds that promote renewable energy. These investments generate a return primarily through the realization of federal tax credits and other tax benefits. The Company accounts for the tax attributes of its renewable energy investments using the deferral method. Under this method, realized investment tax credits and other tax benefits are recognized as a reduction of the renewable energy investments. ​ The Company determined its investment in these tax credit funds was an investment in a variable interest entity (“VIE”). The Company analyzes any investments in VIEs at inception and again if certain triggering events are identified to determine if it is the primary beneficiary. The Company considers a variety of factors in identifying the entity that holds the power to direct matters that most significantly impact the VIE’s economic performance including, but not limited to, the ability to direct financing, leasing, construction and other operating decisions and activities. As of December 31, 2020, the Company had invested in three unconsolidated tax credit fund entities that were considered to be VIEs and concluded it was not the primary beneficiary of any of the entities, as it did not have the power to control the activities that most significantly impact the entities, and has accounted for these investments using the equity method. The Company’s maximum exposure to losses associated with these VIEs is limited to its net investment, which was $19.5 million as of December 31, 2020, and was included in “Other assets, net” on the accompanying Consolidated Balance Sheets. During the years ended December 31, 2020, 2019 and 2018, the Company recognized investment tax credits in the amounts of $170.5 million, $8.5 million and $19.4 million, respectively, all of which were realized through reductions in cash income taxes paid and were reflected as a component of the change in Income taxes payable on the accompanying Consolidated Statements of Cash Flows for the respective years. See Note 16 for further information concerning the Company’s investment in renewable energy tax credits. ​ Self-insurance reserves: The Company uses a combination of insurance and self-insurance mechanisms to provide for potential liabilities for Team Member health care benefits, workers’ compensation, vehicle liability, general liability and property loss. With the exception of certain Team Member health care benefit liabilities, employment related claims and litigation, certain commercial litigation and certain regulatory matters, the Company obtains third-party insurance coverage to limit its exposure. The Company estimates its self-insurance liabilities by considering a number of factors, including historical claims experience and trend-lines, projected medical and legal inflation, growth patterns and exposure forecasts. Certain of these liabilities were recorded at an estimate of their net present value, using a credit-adjusted discount rate. ​ The following table identifies the components of the Company’s self-insurance reserves as of December 31, 2020 and 2019 (in thousands): ​
​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | December 31,
​ |  | 2020 |  | 2019
Self-insurance reserves (undiscounted) | ​ | $ | 213,332 | ​ | $ | 168,397
Self-insurance reserves (discounted) | ​ |  | 202,454 | ​ |  | 156,585
​ The current portion of the Company’s discounted self-insurance reserves totaled $109.2 million and $79.1 million as of December 31, 2020 and 2019, respectively, which was included in “Self-insurance reserves” on the accompanying Consolidated Balance Sheets as of December 31, 2020 and 2019. The remainder was included in “Other liabilities” on the accompanying Consolidated Balance Sheets as of December 31, 2020 and 2019. ​ Warranties: The Company offers warranties on certain merchandise it sells with warranty periods ranging from 30 days to limited lifetime warranties. The risk of loss arising from warranty claims is typically the obligation of the Company’s suppliers. Certain suppliers provide upfront allowances to the Company in lieu of accepting the obligation for warranty claims. For this merchandise, when sold, the Company bears the risk of loss associated with the cost of warranty claims. Differences between supplier allowances received by the Company, in lieu of warranty obligations and estimated warranty expense, are recorded as an adjustment to cost of sales. Estimated warranty costs, which are recorded as obligations at the time of sale, are based on the historical failure rate of each individual product line. The Company’s historical experience has been that failure rates are relatively consistent over time and that the ultimate cost of warranty claims to the Company has been driven by volume of units sold as opposed to fluctuations in failure rates or the variation of the cost of individual claims. See Note 9 for further information concerning the Company’s aggregate product warranty liabilities. ​ Litigation accruals: O’Reilly is currently involved in litigation incidental to the ordinary conduct of the Company’s business. The Company accrues for litigation losses in instances where a material adverse outcome is probable and the Company is able to reasonably estimate the probable loss. The Company accrues for an estimate of material legal costs to be incurred in pending litigation matters. Although the Company cannot ascertain the amount of liability that it may incur from any of these matters, it does not currently believe that, in the aggregate, these matters, taking into account applicable insurance and accruals, will have a material adverse effect on its consolidated financial position, results of operations or cash flows in a particular quarter or annual period. ​ Share repurchases: In January of 2011, the Company’s Board of Directors approved a share repurchase program. Under the program, the Company may, from time to time, repurchase shares of its common stock, solely through open market purchases effected through a broker dealer at prevailing market prices, based on a variety of factors such as price, corporate trading policy requirements and overall market conditions. All shares repurchased under the share repurchase program are retired and recorded under the par value method on the accompanying Consolidated Balance Sheets. See Note 10 for further information concerning the Company’s share repurchase program. ​ Revenue recognition: The Company’s primary source of revenue is derived from the sale of automotive aftermarket parts and merchandise to its customers. Revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied, in an amount representing the consideration the Company expects to receive in exchange for transferring goods to the customer. Generally, the Company’s performance obligations are satisfied when the customer takes possession of the merchandise, which normally occurs immediately at the point of sale or through same day delivery of the merchandise. All sales are recorded net of estimated returns allowances, discounts and taxes. The Company does not recognize revenue related to product warranties, as these are considered assurance warranty obligations. ​ Over-the-counter retail sales to DIY customers are recorded when the customer takes possession of the merchandise. Internet retail sales, included in sales to DIY customers, are recorded when the merchandise is shipped or when the customer picks up the merchandise at a store. Sales to professional service provider customers, also referred to as “commercial sales,” are recorded upon same-day delivery of the merchandise to the customer, generally at the customer’s place of business. Other sales and sales adjustments primarily includes sales to Team Members, wholesale sales to other retailers (“jobber sales”), equipment sales, discounts, rebates, deferred revenue adjustments relating to the Company’s retail loyalty program and adjustments to estimated sales returns allowances. Sales to Team Members are recorded when the Team Member takes possession of the merchandise. Jobber sales are recorded upon shipment of the merchandise from a regional distribution center with same-day delivery to the jobber customer’s location. ​ The Company maintains a retail loyalty program named O’Reilly O’Rewards, which represents a performance obligation. The Company records a deferred revenue liability, based on a breakage adjusted, estimated redemption rate and a corresponding reduction in revenue in periods when loyalty points are earned by members. The Company recognizes revenue and a corresponding reduction to the deferred revenue liability in periods when loyalty program issued coupons are redeemed by members, generally within a period of three months from issuance, or when unredeemed points expire, generally within 12 months after the date they were earned, which satisfies the Company’s performance obligation. See Note 12 for further information concerning the Company’s revenue. ​ Cost of goods sold and selling, general and administrative expenses: The following table illustrates the primary costs classified in each major expense category:
​ | ​ | ​
Cost of goods sold, including warehouse and distribution expenses |  | Selling, general and administrative expenses
Total cost of merchandise sold, including: | ​ | Payroll and benefit costs for store and corporate Team Members
Freight expenses associated with acquiring merchandise and with moving merchandise inventories from the Company’s distribution centers to the stores | ​ | Occupancy costs of store and corporate facilities
Defective merchandise and warranty costs | ​ | Depreciation and amortization related to store and corporate assets
Supplier allowances and incentives, including: | ​ | Vehicle expenses for store delivery services
Allowances that are not reimbursements for specific, incremental and identifiable costs | ​ | Self-insurance costs
Cash discounts on payments to suppliers | ​ | Closed store expenses
Costs associated with the Company’s supply chain, including: | ​ | Other administrative costs, including:
Payroll and benefit costs | ​ | Accounting, legal and other professional services
Warehouse occupancy costs | ​ | Bad debt, banking and credit card fees
Transportation costs | ​ | Supplies
Depreciation | ​ | Travel
Inventory shrinkage | ​ | Advertising costs
​ Advertising expenses: Advertising expense consists primarily of expenses related to the Company’s integrated marketing program, which includes radio, in-store, digital and social media promotions, as well as sports and event sponsorships and direct mail and newspaper promotional distribution. The Company expenses advertising costs as incurred. The Company also participates in cooperative advertising arrangements with certain of its suppliers. Advertising expense, net of cooperative advertising allowances from suppliers that were incremental to the advertising program, specific to the product or event and identifiable for accounting purposes, total $73.8 million, $79.3 million and $81.4 million for the years ended December 31, 2020, 2019 and 2018, respectively, which were included in “Selling, general and administrative expenses” on the accompanying Consolidated Statements of Income. ​ Share-based compensation and benefit plans: The Company sponsors share-based compensation plans and benefit plans. The Company recognizes compensation expense over the requisite service period for its share-based plans based on the fair value of the awards on the date of the grant, award or issuance and accounts for forfeitures as they occur. Share-based plans include stock option awards, restricted stock awards and stock appreciation rights issued under the Company’s incentive plans and stock issued through the Company’s employee stock purchase plan. See Note 13 for further information concerning the Company’s share-based compensation and benefit plans. ​ Pre-opening expenses: Costs associated with the opening of new stores, which consist primarily of payroll and occupancy costs, are charged to “Selling, general and administrative expenses” on the accompanying Consolidated Statements of Income as incurred. Costs associated with the opening of new distribution centers, which consist primarily of payroll and occupancy costs, are included in “Cost of goods sold, including warehouse and distribution expenses” on the accompanying Consolidated Statements of Income as incurred. ​ Interest expense: The Company capitalizes interest costs as a component of construction in progress, based on the weighted-average interest rates incurred on its long-term borrowings. Total interest costs capitalized for the years ended December 31, 2020, 2019 and 2018, were $10.2 million, $13.0 million and $9.1 million, respectively, which were included in “Interest expense” on the accompanying Consolidated Statements of Income. ​ In conjunction with the issuance or amendment of long-term debt instruments, the Company incurs various costs, including debt registration fees, accounting and legal fees and underwriter and book runner fees. Debt issuance costs related to the Company’s long-term unsecured senior notes are recorded as a reduction of the principal amount of the corresponding unsecured senior notes. Debt issuance costs related to the Company’s unsecured revolving credit facility are recorded as an asset. These debt issuance costs have been deferred and are being amortized over the term of the corresponding debt instrument and the amortization expense is included in “Interest expense” on the accompanying Consolidated Statements of Income. Deferred debt issuance costs totaled $22.3 million and $18.0 million, net of accumulated amortization, as of December 31, 2020 and 2019, respectively, of which $0.6 million and $1.1 million were included in “Other assets, net” as of December 31, 2020 and 2019, respectively, with the remainder included in “Long-term debt” on the accompanying Consolidated Balance Sheets. ​ The Company issued its long-term unsecured senior notes at a discount. The original issuance discounts on the senior notes are recorded as a reduction of the principal amount of the corresponding senior notes and are accreted over the term of the applicable senior note, with the accretion expense included in “Interest expense” on the accompanying Consolidated Statements of Income. Original issuance discounts, net of accretion, totaled $5.1 million and $3.5 million as of December 31, 2020 and 2019, respectively. ​ See Note 8 for further information concerning debt issuance costs and original issuance discounts associated with the Company’s issuances of long-term debt instruments. ​ Income taxes: The Company accounts for income taxes using the liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on differences between the U.S. GAAP basis and tax basis of assets and liabilities using enacted tax rules and rates currently scheduled to be in effect for the year in which the differences are expected to reverse. Tax carry forwards are also recognized in deferred tax assets and liabilities under this method. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period of the enactment date. The Company would record a valuation allowance against deferred tax assets to the extent it is more likely than not the amount will not be realized, based upon evidence available at the time of the determination and any change in the valuation allowance is recorded in the period of a change in such determination. The Company did not establish a valuation allowance for deferred tax assets as of December 31, 2020 and 2019, as it was considered more likely than not that deferred tax assets were realizable through a combination of future taxable income, the realization of deferred tax liabilities and tax planning strategies. ​ The Company regularly reviews its potential tax liabilities for tax years subject to audit. The amount of such liabilities is based on various factors, such as differing interpretations of tax regulations by the responsible tax authority, experience with previous tax audits and applicable tax law rulings. In management’s opinion, adequate provisions for income taxes have been made for all years presented. The estimates of the Company’s potential tax liabilities contain uncertainties because management must use judgment to estimate the exposures associated with the Company’s various tax positions and actual results could differ from estimates. See Note 16 for further information concerning the Company’s income taxes. ​ Earnings per share: Basic earnings per share is calculated by dividing net income by the weighted-average number of common shares outstanding during the fiscal period. Diluted earnings per share is calculated by dividing the weighted-average number of common shares outstanding plus the common stock equivalents associated with the potential impact of dilutive stock options. Certain common stock equivalents that could potentially dilute basic earnings per share in the future were not included in the fully diluted computation because they would have been antidilutive. Generally, stock options are antidilutive and excluded from the earnings per share calculation when the exercise price exceeds the market price of the common shares. See Note 17 for further information concerning the Company’s common stock equivalents. ​ New accounting pronouncements: In June of 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standard Update (“ASU”) No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). Under ASU 2016-13, businesses and other organizations are required to present financial assets, measured at amortized costs basis, at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis, such as trade receivables. The measurement of expected credit loss will be based on historical experience, current conditions and reasonable and supportable forecasts that affect the collectibility of the reported amount. For public companies, ASU 2016-13 is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. The Company adopted this guidance using the modified retrospective adoption method beginning with its first quarter ending March 31, 2020, and applied it to all applicable accounts. The application of this new guidance did not have a material impact on the Company’s consolidated financial condition, results of operations or cash flows. See Note 4 for further information concerning the Company’s allowance for accounts receivable.
