NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

March 31, 2018

NOTE 1 - BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements of O’Reilly Automotive, Inc. and its subsidiaries (the “Company” or “O’Reilly”) have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2018, are not necessarily indicative of the results that may be expected for the year ended December 31, 2018. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

NOTE 2 – FAIR VALUE MEASUREMENTS

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.

Financial assets and liabilities measured at fair value on a recurring basis:

The Company invests in various marketable securities with the intention of selling these securities to fulfill its future unsecured obligation under the Company’s nonqualified deferred compensation plan. See Note 7 for further information concerning the Company’s benefit plans.

The Company’s marketable securities were accounted for as trading securities and the carrying amount of its marketable securities were included in “Other assets, net” on the accompanying Condensed Consolidated Balance Sheets as of March 31, 2018, and December 31, 2017. The Company recorded a decrease in fair value related to its marketable securities in the amount of $0.1 million for the three months ended March 31, 2018, and an increase in fair value related to its marketable securities in the amount of $0.9 million for the three months ended March 31, 2017, which were included in “Other income (expense)” on the accompanying Condensed Consolidated Statements of Income.

The tables below identify the estimated fair value of the Company’s marketable securities, determined by reference to quoted market prices (Level 1), as of March 31, 2018, and December 31, 2017 (in thousands):



	March 31, 2018
	Quoted Prices in Active Markets for Identical Instruments (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Marketable securities	$	26,179	$	—	$	—	$	26,179



	December 31, 2017
	Quoted Prices in Active Markets for Identical Instruments (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Marketable securities	$	25,706	$	—	$	—	$	25,706

Non-financial assets and liabilities measured at fair value on a nonrecurring basis:

Certain long-lived non-financial assets and liabilities may be required to be measured at fair value on a nonrecurring basis in certain circumstances, including when there is evidence of impairment. These non-financial assets and liabilities may include assets acquired

in a business combination or property and equipment that are determined to be impaired. As of March 31, 2018, and December 31, 2017, the Company did not have any non-financial assets or liabilities that had been measured at fair value subsequent to initial recognition.

Fair value of financial instruments:

The carrying amounts of the Company’s senior notes and unsecured revolving credit facility borrowings are included in “Long-term debt” on the accompanying Condensed Consolidated Balance Sheets as of March 31, 2018, and December 31, 2017. See Note 3 for further information concerning the Company’s senior notes and unsecured revolving credit facility.

The table below identifies the estimated fair value of the Company’s senior notes, using the market approach. The fair value as of March 31, 2018, and December 31, 2017, was determined by reference to quoted market prices of the same or similar instruments (Level 2) (in thousands):



	March 31, 2018				December 31, 2017
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
Senior Notes	$	2,633,066	$	2,662,350	$	2,632,390	$	2,728,167

The carrying amount of the Company’s unsecured revolving credit facility approximates fair value, as borrowings under the facility bear variable interest at current market rates.

The accompanying Condensed Consolidated Balance Sheets include other financial instruments, including cash and cash equivalents, accounts receivable, amounts receivable from suppliers and accounts payable. Due to the short-term nature of these financial instruments, the Company believes that the carrying values of these instruments approximate their fair values.

NOTE 3 – FINANCING

The following table identifies the amounts included in “Long-term debt” on the accompanying Condensed Consolidated Balance Sheets as of March 31, 2018, and December 31, 2017 (in thousands):

Unsecured revolving credit facility:

On April 5, 2017, the Company entered into a credit agreement (the “Credit Agreement”). The Credit Agreement provides for a $1.2 billion unsecured revolving credit facility (the “Revolving Credit Facility”) arranged by JPMorgan Chase Bank, N.A., which is scheduled to mature in April 2022. The Credit Agreement includes a $200 million sub-limit for the issuance of letters of credit and a $75 million sub-limit for swing line borrowings under the Revolving Credit Facility. As described in the Credit Agreement governing the Revolving Credit Facility, the Company may, from time to time, subject to certain conditions, increase the aggregate commitments under the

Revolving Credit Facility by up to $600 million, provided that the aggregate amount of the commitments does not exceed $1.8 billion at any time.

As of March 31, 2018, and December 31, 2017, the Company had outstanding letters of credit, primarily to support obligations related to workers’ compensation, general liability and other insurance policies, in the amounts of $36.9 million and $36.8 million, respectively, reducing the aggregate availability under the Credit Agreement by those amounts.

Borrowings under the Revolving Credit Facility (other than swing line loans) bear interest, at the Company’s option, at either an Alternate Base Rate or an Adjusted LIBO Rate (both as defined in the Credit Agreement) plus an applicable margin. Swing line loans made under the Revolving Credit Facility bear interest at an Alternate Base Rate plus the applicable margin for Alternate Base Rate loans. In addition, the Company pays a facility fee on the aggregate amount of the commitments under the Credit Agreement in an amount equal to a percentage of such commitments. The interest rate margins and facility fee are based upon the better of the ratings assigned to the Company’s debt by Moody’s Investor Service, Inc. and Standard & Poor’s Ratings Services, subject to limited exceptions. As of March 31, 2018, based upon the Company’s current credit ratings, its margin for Alternate Base Rate loans was 0.000%, its margin for Eurodollar Revolving Loans was 0.900% and its facility fee was 0.100%.

The Credit Agreement contains certain covenants, including limitations on subsidiary indebtedness, a minimum consolidated fixed charge coverage ratio of 2.50:1.00 and a maximum consolidated leverage ratio of 3.50:1.00. The consolidated fixed charge coverage ratio includes a calculation of earnings before interest, taxes, depreciation, amortization, rent and non-cash share-based compensation expense to fixed charges. Fixed charges include interest expense, capitalized interest and rent expense. The consolidated leverage ratio includes a calculation of adjusted debt to earnings before interest, taxes, depreciation, amortization, rent and non-cash share-based compensation expense. Adjusted debt includes outstanding debt, outstanding stand-by letters of credit and similar instruments, five-times rent expense and excludes any premium or discount recorded in conjunction with the issuance of long-term debt. In the event that the Company should default on any covenant (subject to customary grace periods, cure rights and materiality thresholds) contained in the Credit Agreement, certain actions may be taken, including, but not limited to, possible termination of commitments, immediate payment of outstanding principal amounts plus accrued interest and other amounts payable under the Credit Agreement and litigation from lenders. As of March 31, 2018, the Company remained in compliance with all covenants under the Credit Agreement.

Senior notes:

The Company has issued a cumulative $2.7 billion aggregate principal amount of unsecured senior notes, which are due between 2021 and 2027, with UMB Bank, N.A. as trustee. Interest on the senior notes, ranging from 3.550% to 4.875%, is payable semi-annually and is computed on the basis of a 360-day year. Each of the senior notes is subject to certain customary covenants, with which the Company complied as of March 31, 2018.

NOTE 4 – WARRANTIES

The Company provides 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.

The Company’s product warranty liabilities are included in “Other current liabilities” on the accompanying Condensed Consolidated Balance Sheets as of March 31, 2018, and December 31, 2017. The following table identifies the changes in the Company’s aggregate product warranty liabilities for the three months ended March 31, 2018 (in thousands):



Warranty liabilities, balance at December 31, 2017	$	44,398
Warranty claims	(19,554		)
Warranty accruals	20,797
Warranty liabilities, balance at March 31, 2018	$	45,641

NOTE 5 – SHARE REPURCHASE PROGRAM

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. The Company’s Board of Directors may increase or otherwise modify, renew, suspend or terminate the share repurchase program at any time, without prior notice. As announced on February 7, 2018, the Company’s Board of Directors approved a resolution to increase the authorization amount under the share repurchase program by an additional $1.0 billion, resulting in a cumulative authorization amount of $10.8 billion. The additional authorization is effective for a three-year period, beginning on its announcement date.

The following table identifies shares of the Company’s common stock that have been repurchased as part of the Company’s publicly announced share repurchase program (in thousands, except per share data):



	For the Three Months Ended March 31,
	2018		2017
Shares repurchased	2,188		1,829
Average price per share	$	251.08	$	268.09
Total investment	$	549,428	$	490,312

As of March 31, 2018, the Company had $1.2 billion remaining under its share repurchase program. Subsequent to the end of the first quarter and through May 7, 2018, the Company repurchased an additional 0.5 million shares of its common stock under its share repurchase program, at an average price of $238.90, for a total investment of $117.5 million. The Company has repurchased a total of 68.9 million shares of its common stock under its share repurchase program since the inception of the program in January of 2011 and through May 7, 2018, at an average price of $140.75, for a total aggregate investment of $9.7 billion.

NOTE 6 – REVENUE

The table below identifies the Company’s revenues disaggregated by major customer type for the three months ended March 31, 2018 and 2017 (in thousands):



	For the Three Months Ended March 31,
	2018		2017
Sales to do-it-yourself customers	$	1,272,414	$	1,217,146
Sales to professional service provider customers	975,009		905,925
Other sales and sales adjustments	35,258		33,188
Total sales	$	2,282,681	$	2,156,259

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. The Company’s primary source of revenue is derived from the sale of automotive aftermarket parts and merchandise to its customers. 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; see Note 4 for information concerning the expected costs associated with the Company’s assurance warranty obligations. See Note 10 for information regarding the adoption implementation of Accounting Standard Update No. 2014-09, “Revenue from Contracts with Customers (Topic 606).”

Over-the-counter retail sales to do-it-yourself (“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.

As of March 31, 2018, and December 31, 2017, the Company had recorded a deferred revenue liability of $4.6 million and $4.7 million, respectively, related to its loyalty program, which were included in “Other liabilities” on the accompanying Condensed Consolidated Balance Sheets. During the three months ended March 31, 2018 and 2017, the Company recognized $3.2 million and $3.4 million, respectively, of deferred revenue related to its loyalty program, which were included in “Sales” on the accompanying Condensed Consolidated Statements of Income.

NOTE 7 – SHARE-BASED COMPENSATION AND BENEFIT PLANS

The Company recognizes share-based compensation expense based on the fair value of the grants, awards or shares at the time of the grant, award or issuance. Share-based compensation includes stock option awards issued under the Company’s employee incentive plans and director stock plan, restricted stock awarded under the Company’s employee incentive plans and director stock plan and stock issued through the Company’s employee stock purchase plan.

Stock options:

The Company’s stock-based incentive plans provide for the granting of stock options for the purchase of common stock of the Company to directors and certain key employees of the Company. Options are granted at an exercise price that is equal to the closing market price of the Company’s common stock on the date of the grant. Director options granted under the plans expire after seven years and are fully vested after six months. Employee options granted under the plans expire after ten years and typically vest 25% per year, over four years. The Company records compensation expense for the grant-date fair value of the option awards evenly over the vesting period or the minimum required service period.

The table below identifies stock option activity under these plans during the three months ended March 31, 2018 (in thousands, except per share data):



	Shares		Weighted-Average Exercise Price
Outstanding at December 31, 2017	2,364		$	137.08
Granted	201		252.78
Exercised	(155	)	71.47
Forfeited	(9	)	252.78
Outstanding at March 31, 2018	2,401		$	150.59
Exercisable at March 31, 2018	1,507		$	91.61

The fair value of each stock option award is estimated on the date of the grant using the Black-Scholes option pricing model. The Black-Scholes model requires the use of assumptions, including the risk free rate, expected life, expected volatility and expected dividend yield.


•	Risk-free interest rate – The United States Treasury rates in effect at the time the options are granted for the options’ expected life.


•


•	Expected life – Represents the period of time that options granted are expected to be outstanding. The Company uses historical experience to estimate the expected life of options granted.


•	Expected volatility – Measure of the amount, by which the Company’s stock price is expected to fluctuate, based on a historical trend.


•	Expected dividend yield – The Company has not paid, nor does it have plans in the foreseeable future to pay, any dividends.

The table below identifies the weighted-average assumptions used for grants awarded during the three months ended March 31, 2018 and 2017:



	For the Three Months Ended March 31,
	2018		2017
Risk free interest rate	2.58	%	2.09	%
Expected life	6.3 Years		5.9 Years
Expected volatility	23.7	%	22.3	%
Expected dividend yield	—	%	—	%

The following table summarizes activity related to stock options awarded by the Company for the three months ended March 31, 2018 and 2017 (in thousands, except per share data):



	For the Three Months Ended March 31,
	2018		2017
Compensation expense for stock options awarded	$	4,292	$	4,209
Income tax benefit from compensation expense related to stock options	1,078		1,593
Weighted-average grant-date fair value of options awarded	$	75.42	$	70.34

The remaining unrecognized compensation expense related to unvested stock option awards at March 31, 2018, was $37.3 million, and the weighted-average period of time over which this cost will be recognized is 2.9 years.

Other share-based compensation plans:

The Company sponsors other share-based compensation plans: an employee stock purchase plan (the “ESPP”), which permits all eligible employees to purchase shares of the Company’s common stock at 85% of the fair market value, and a director stock plan, which provides for the award of shares of restricted stock to the Company’s independent directors, that vest evenly over a three-year period and are held in escrow until such vesting has occurred. The fair value of shares issued under the ESPP is based on the average of the high and low market prices of the Company’s common stock during the offering periods, and compensation expense is recognized based on the discount between the fair value and the employee purchase price for the shares sold to employees. The fair value of shares awarded under the director stock plan is based on the closing market price of the Company’s common stock on the date of the award, and compensation expense is recorded evenly over the vesting period or the minimum required service period.

The table below summarizes activity related to the Company’s other share-based compensation plans for the three months ended March 31, 2018 and 2017 (in thousands):



	For the Three Months Ended March 31,
	2018		2017
Compensation expense for shares issued under the ESPP	$	543	$	541
Income tax benefit from compensation expense related to shares issued under the ESPP	136		205
Compensation expense for restricted shares awarded	341		678
Income tax benefit from compensation expense related to restricted awards	$	86	$	257

Profit sharing and savings plan:

The Company sponsors a contributory profit sharing and savings plan (the “401(k) Plan”) that covers substantially all employees who are at least 21 years of age and have completed one year of service. The Company makes matching contributions equal to 100% of the first 2% of each employee’s wages that are contributed and 25% of the next 4% of each employee’s wages that are contributed. An employee generally must be employed on December 31 to receive that year’s Company matching contribution, with the matching contribution funded annually at the beginning of the subsequent year following the year in which the matching contribution was earned. The Company may also make additional discretionary profit sharing contributions to the plan on an annual basis as determined by the Board of Directors. The Company did not make any discretionary contributions to the 401(k) Plan during the three months ended March 31, 2018 or 2017. The Company expensed matching contributions under the 401(k) Plan in the amounts of $5.7 million and $5.5 million for the three months ended March 31, 2018 and 2017, respectively, which were included in “Selling, general and administrative expenses” on the accompanying Condensed Consolidated Statements of Income.

Nonqualified deferred compensation plan:

The Company sponsors a nonqualified deferred compensation plan (the “Deferred Compensation Plan”) for highly compensated employees whose contributions to the 401(k) Plan are limited due to the application of the annual limitations under the Internal Revenue Code. The Deferred Compensation Plan provides these employees with the opportunity to defer the full 6% of matched compensation, including salary and incentive based compensation that was precluded under the Company’s 401(k) Plan, which is then matched by the Company using the same formula as the 401(k) Plan. An employee generally must be employed on December 31 to receive that year’s Company matching contribution, with the matching contribution funded annually at the beginning of the subsequent year following the year in which the matching contribution was earned. In the event of bankruptcy, the assets of this plan are available to satisfy the claims of general creditors. The Company has an unsecured obligation to pay, in the future, the value of the deferred compensation and Company match, adjusted to reflect the performance, whether positive or negative, of selected investment measurement options chosen by each participant during the deferral period. The liability for compensation deferred under the Deferred Compensation Plan was $26.2 million

and $25.7 million as of March 31, 2018, and December 31, 2017, respectively, which was included in “Other liabilities” on the accompanying Condensed Consolidated Balance Sheets. The Company expensed matching contributions under the Deferred Compensation Plan in the amount of less than $0.1 million for the three months ended March 31, 2018 and 2017, which were included in “Selling, general and administrative expenses” on the accompanying Condensed Consolidated Statements of Income.

NOTE 8 – EARNINGS PER SHARE

The following table illustrates the computation of basic and diluted earnings per share for the three months ended March 31, 2018 and 2017 (in thousands, except per share data):



	For the Three Months Ended March 31,
	2018		2017
Numerator (basic and diluted):
Net income	$	304,906	$	264,934

Denominator:
Weighted-average common shares outstanding – basic	83,530		92,001
Effect of stock options ⁽¹⁾	993		1,494
Weighted-average common shares outstanding – assuming dilution	84,523		93,495

Earnings per share:
Earnings per share-basic	$	3.65	$	2.88
Earnings per share-assuming dilution	$	3.61	$	2.83

Antidilutive potential common shares not included in the calculation of diluted earnings per share:
Stock options ⁽¹⁾	761		478
Weighted-average exercise price per share of antidilutive stock options ⁽¹⁾	$	259.28	$	266.71


⁽¹⁾	See Note 7 for further information concerning the terms of the Company’s share-based compensation plans.

For the three months ended March 31, 2018 and 2017, the computation of diluted earnings per share did not include certain securities. These securities represent underlying stock options not included in the computation of diluted earnings per share, because the inclusion of such equity awards would have been antidilutive.

NOTE 9 – LEGAL MATTERS

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.

As previously reported, on June 18, 2015, a jury in Greene County, Missouri, returned an unfavorable verdict in a litigated contract dispute in the matter Meridian Creative Alliance vs. O’Reilly Automotive Stores, Inc. et. al. in the amount of $12.5 million. As previously reported, the verdict was appealed, reversed in part and remanded to the trial court for a new trial. In the interim period, the matter was resolved at mediation for an amount within the previously reported accrual.

NOTE 10 - RECENT ACCOUNTING PRONOUNCEMENTS

Topic 606, an entity is required to follow a five-step process to determine the amount of revenue to recognize when promised goods or services are transferred to customers. Topic 606 offers specific accounting guidance for costs to obtain or fulfill a contract with a customer. In addition, an entity is required to disclose sufficient information to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted this guidance using the modified retrospective transition method with its first quarter ended March 31, 2018. Results of the three months ended March 31, 2018, were presented under Topic 606, while amounts in prior periods were not adjusted and continue to be reported under the accounting standard in effect for the prior periods. The adoption of Topic 606 did not have a material impact on the Company’s business process, internal controls, systems, consolidated financial condition, results of operations or cash flows; as such, a cumulative effective adjustment was not recorded to opening retained earnings. See Note 6 for information concerning the Company’s revenue recognition policy.

In February of 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. The Company will adopt this guidance beginning with its first quarter ending March 31, 2019. The Company has established a task force, composed of multiple functional groups inside of the Company, which is currently in the process of evaluating critical components of this new guidance and the potential impact of the guidance on the Company’s financial position, results of operations and cash flows. Based on the preliminary work completed, the Company is considering the potential implications of the new standard on determining the discount rate to be used in valuing new and existing leases, the treatment of existing favorable and unfavorable lease agreements acquired in connection with previous acquisitions, procedural and operational changes that may be necessary to comply with the provisions of the guidance and all applicable financial statement disclosures required by the new guidance, all of which are areas that could potentially be impacted by adoption of the guidance. At this time, the task force has not completed its full evaluation; however, the Company believes the adoption of the new guidance will have a material impact on the total assets and total liabilities reported on the Company’s consolidated balance sheets.

In June of 2016, the FASB issued 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 will adopt this guidance beginning with its first quarter ending March 31, 2020. The application of this new guidance is not expected to have a material impact on the Company’s consolidated financial condition, results of operations or cash flows.

In January of 2017, the FASB issued ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). ASU 2017-04 eliminates the second step in the previous process for goodwill impairment testing; instead, the test is now a one-step process that calls for goodwill impairment loss to be measured as the excess of the reporting unit’s carrying amount over its fair value. For public companies, ASU 2017-04 is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period, and requires prospective adoption, with early adoption after January 1, 2017. The Company will adopt this guidance beginning with its first quarter ending March 31, 2019. The application of this new guidance is not expected to have a material impact on the Company’s consolidated financial condition, results of operations or cash flows.

OVERVIEW

We are a specialty retailer of automotive aftermarket parts, tools, supplies, equipment and accessories in the United States. We are one of the largest U.S. automotive aftermarket specialty retailers, selling our products to both do-it-yourself (“DIY”) customers and professional service providers – our “dual market strategy.” Our stores carry an extensive product line consisting of new and remanufactured automotive hard parts, maintenance items, accessories, a complete line of auto body paint and related materials, automotive tools and professional service provider service equipment. Our extensive product line includes an assortment of products that are differentiated by quality and price for most of the product lines we offer. For many of our product offerings, this quality differentiation reflects “good,” “better,” and “best” alternatives. Our sales and total gross margin dollars are highest for the “best” quality category of products. Consumers’ willingness to select products at a higher point on the value spectrum is a driver of sales and profitability in our industry. Our stores also offer enhanced services and programs to our customers, including used oil, oil filter and battery recycling; battery, wiper and bulb replacement; battery diagnostic testing; electrical and module testing; check engine light code extraction; loaner tool program; drum and rotor resurfacing; custom hydraulic hoses; professional paint shop mixing and related materials; and machine shops.

Our strategy is to open new stores to achieve greater penetration into existing markets and expansion into new, contiguous markets. We typically open new stores either by (i) constructing a new facility or renovating an existing one on property we purchase or lease and stocking the new store with fixtures and inventory; (ii) acquiring an independently owned auto parts store, typically by the purchase of substantially all of the inventory and other assets (other than realty) of such store; or (iii) purchasing multi-store chains. We plan to open 200 net, new stores in 2018. We believe our investment in store growth will be funded with the cash flows expected to be generated by our existing operations and through available borrowings under our existing unsecured revolving credit facility. During the three months ended March 31, 2018, we opened 78 stores and did not close any stores and, as of that date, operated 5,097 stores in 47 states.

Operating within the retail industry, we are influenced by a number of general macroeconomic factors including, but not limited to, fuel costs, unemployment rates, consumer preferences and spending habits, and competition. We have ongoing initiatives aimed at tailoring our product offering to adjust to customers’ changing preferences, and we also have initiatives focused on marketing and training to educate customers on the advantages of ongoing vehicle maintenance, as well as “purchasing up” on the value spectrum.

We believe the key drivers of current and future demand for the products sold within the automotive aftermarket include the number of U.S. miles driven, number of U.S. registered vehicles, new light vehicle registrations, average vehicle age and unemployment.

•

Number of Miles Driven – The number of total miles driven in the U.S. influences the demand for repair and maintenance products sold within the automotive aftermarket. In total, vehicles in the U.S. are driven approximately three trillion miles per year, resulting in ongoing wear and tear and a corresponding continued demand for the repair and maintenance products necessary to keep these vehicles in operation. According to the Department of Transportation, the number of total miles driven in the U.S. increased 1.2%, 2.4% and 3.5% in 2017, 2016 and 2015, respectively, and through February of 2018, year-to-date miles driven increased 0.2%. We would expect to continue to see modest improvements in total miles driven in the U.S., supported by an increasing number of registered vehicles on the road, resulting in continued demand for automotive aftermarket products.

•

Number of U.S. Registered Vehicles, New Light Vehicle Registrations and Average Vehicle Age – The total number of vehicles on the road and the average age of the vehicle population heavily influence the demand for products sold within the automotive aftermarket industry. As reported by The Auto Care Association, the total number of registered vehicles increased 7% from 2006 to 2016, bringing the number of light vehicles on the road to 264 million by the end of 2016. For the year ended December 31, 2017, the seasonally adjusted annual rate of light vehicle sales in the U.S. (“SAAR”) was approximately 17.8 million, and for 2018, the SAAR is estimated to be approximately 17.4 million, contributing to the continued growth in the total number of registered vehicles on the road. In the past decade, vehicle scrappage rates have remained relatively stable, ranging from 4.3% to 5.7% annually. As a result, over the past decade, the average age of the U.S. vehicle population has increased, growing 22%, from 9.5 years in 2006 to 11.6 years in 2016. We believe this increase in average age can be attributed to better engineered and manufactured vehicles, which can be reliably driven at higher mileages due to better quality power trains and interiors and exteriors, and the consumer’s willingness to invest in maintaining these higher-mileage, better built vehicles. As the average age of vehicles on the road increases, a larger percentage of miles are being driven by vehicles that are outside of a manufacturer warranty. These out-of-warranty, older vehicles generate strong demand for automotive aftermarket products as they go through more routine maintenance cycles, have more frequent mechanical failures and generally require more maintenance than newer vehicles. We believe consumers will continue to invest in these reliable, higher-quality, higher-mileage vehicles and these investments, along with an increasing total light vehicle fleet, will support continued demand for automotive aftermarket products.

•

Unemployment – Unemployment, underemployment, the threat of future joblessness and the uncertainty surrounding the overall economic health of the U.S. have a negative impact on consumer confidence and the level of consumer discretionary spending. Long-term trends of high unemployment have historically impeded the growth of annual miles driven, as well as decrease consumer discretionary spending, both of which negatively impact demand for products sold in the automotive aftermarket industry. The U.S. unemployment rate was 4.1% for both March 31, 2018, and December 31, 2017. We believe total employment should remain at healthy levels supporting the trend of modest growth of total miles driven in the U.S. and the continued demand for automotive aftermarket products.

We remain confident in our ability to gain market share in our existing markets and grow our business in new markets by focusing on our dual market strategy and the core O’Reilly values of hard work and excellent customer service.

RESULTS OF OPERATIONS

Sales:

Sales for the three months ended March 31, 2018, increased $126 million to $2.28 billion from $2.16 billion for the same period one year ago, representing an increase of 6%. Comparable store sales for stores open at least one year increased 3.4% and 0.8% for the three months ended March 31, 2018 and 2017, respectively. Comparable store sales are calculated based on the change in sales for stores open at least one year and exclude sales of specialty machinery, sales to independent parts stores and sales to Team Members.

The following table presents the components of the increase in sales for the three months ended March 31, 2018 (in millions):



	Increase in Sales for the Three Months Ended March 31, 2018, Compared to the Same Period in 2017
Store sales:
Comparable store sales	$	72
Non-comparable store sales:
Sales for stores opened throughout 2017, excluding stores open at least one year that are included in comparable store sales	44
Sales for stores opened throughout 2018	9
Sales in 2017 for stores that have closed	(1		)
Non-store sales:
Includes sales of machinery and sales to independent parts stores and Team Members	2
Total increase in sales	$	126

We believe the increased sales achieved by our stores are the result of store growth, the high levels of customer service provided by our well-trained and technically proficient Team Members, superior inventory availability, including same day and over-night access to inventory in our regional distribution centers, enhanced services and programs offered in our stores, a broader selection of product offerings in most stores with a dynamic catalog system to identify and source parts, a targeted promotional and advertising effort through a variety of media and localized promotional events, continued improvement in the merchandising and store layouts of our stores, compensation programs for all store Team Members that provide incentives for performance and our continued focus on serving both DIY and professional service provider customers.

Our comparable store sales increase for the three months ended March 31, 2018, was driven by an increase in average ticket values, partially offset by slightly negative transaction counts. Average ticket values for both DIY and professional service provider customers were positive; however, position transaction counts for professional service provider customers were offset by negative DIY customer transaction counts. The improvement in average ticket values was the result of the increasing complexity and cost of replacement parts necessary to maintain the current population of better engineered and more technically advanced vehicles. These better engineered, more technically advanced vehicles require less frequent repairs, as the component parts are more durable and last for longer periods of time. This decrease in repair frequency creates pressure on customer transaction counts. However when repairs are needed, the cost of replacement parts is, on average, greater, which is a benefit to average ticket values. In addition, DIY customer transaction counts were negatively impacted by the delay in spring weather in some of our markets during the current period, which negatively impacted our DIY customers’ willingness to perform maintenance on their vehicles in those affected markets.

We opened 78 net, new stores during the three months ended March 31, 2018, respectively, compared to 59 net, new stores for the three months ended March 31, 2017, respectively. As of March 31, 2018, we operated 5,097 stores in 47 states compared to 4,888 stores in 47 states at March 31, 2017. We anticipate total new store growth to be 200 net, new store openings in 2018.

Gross profit:

Gross profit for the three months ended March 31, 2018, increased to $1.20 billion (or 52.6% of sales) from $1.13 billion (or 52.5% of sales) for the same period one year ago, representing an increase of 6%. The increase in gross profit dollars for the three months ended March 31, 2018, was primarily the result of sales from new stores and the increase in comparable store sales at existing stores. The increase in gross profit as a percentage of sales for the three months ended March 31, 2018, was primarily due to a smaller non-cash last-in, first-out (“LIFO”) impact, partially offset by a decrease in capitalized distribution costs and increased transportation costs. The smaller non-cash LIFO impact was the result of fewer product acquisition cost improvements in the current period, as compared to the same period in the prior year, as well as the impact from commodity cost increases. Our policy is to not write up inventory in excess of replacement cost, and accordingly, we are effectively valuing our inventory at replacement cost. During the three months ended March 31, 2018 and 2017, our LIFO costs were written down by approximately $1 million and $7 million, respectively, to reflect replacement cost. The decrease in capitalized distribution costs was the result of a smaller increase in inventory levels during the current period, as compared to the same period in the prior year. The increase in transportation costs is primarily do to increased contract delivery and fuel prices, as compared to the same period in the prior year.

Selling, general and administrative expenses:

Selling, general and administrative expenses (“SG&A”) for the three months ended March 31, 2018, increased to $778 million (or 34.1% of sales) from $728 million (or 33.8% of sales) for the same period one year ago, representing an increase of 7%. The increase in total SG&A dollars for the three months ended March 31, 2018, was primarily the result of additional Team Members, facilities and vehicles

to support our increased sales and store count, and the planned reinvestment of a portion of the tax savings we anticipate to realize as a result of the U.S. Tax Cuts and Jobs Act, enacted in December 2017 (the “Tax Act”). For the full year ended December 31, 2018, we estimate these reinvestments will result in approximately 70 basis points of operating profit headwind. The increase in SG&A as a percentage of sales for the three months ended March 31, 2018, was primarily due to our tax savings reinvestment initiatives.

Operating income:

As a result of the impacts discussed above, operating income for the three months ended March 31, 2018, increased to $423 million (or 18.5% of sales) from $403 million (or 18.7% of sales) for the same period one year ago, representing an increase of 5%.

Other income and expense:

Total other expense for the three months ended March 31, 2018, increased to $27 million (or 1.2% of sales) from $18 million (or 0.8% of sales) for the same period one year ago, representing an increase of 53%. The increase in total other expense for the three months ended March 31, 2018, was primarily the result of increased interest expense on higher average outstanding borrowings.

Income taxes:

Our provision for income taxes for the three months ended March 31, 2018, decreased to $91 million (or 4.0% of sales) from $120 million (or 5.6% of sales) for the same period one year ago, representing a decrease of 25%. Our effective tax rate for the three months ended March 31, 2018, was 22.9% of income before income taxes, compared to 31.2% for the same period one year ago. The decrease in our provision for income taxes and our effective tax rate for the three months ended March 31, 2018, was primarily the result of the lower federal corporate tax rate set forth by the Tax Act, partially offset by lower excess tax benefits from share-based compensation. During the three months ended March 31, 2018 and 2017, excess tax benefits from share-based compensation were approximately $6 million and $23 million, respectively.

Net income:

As a result of the impacts discussed above, net income for the three months ended March 31, 2018, increased to $305 million (or 13.4% of sales) from $265 million (or 12.3% of sales) for the same period one year ago, representing an increase of 15%.

Earnings per share:

Our diluted earnings per common share for the three months ended March 31, 2018, increased 28% to $3.61 on 85 million shares from $2.83 on 93 million shares for the same period one year ago.

LIQUIDITY AND CAPITAL RESOURCES

Our long-term business strategy requires capital to open new stores, fund strategic acquisitions, expand distribution infrastructure, operate and maintain existing stores and may include the opportunistic repurchase of shares of our common stock through our Board-approved share repurchase program. The primary sources of our liquidity are funds generated from operations and borrowed under our unsecured revolving credit facility. Decreased demand for our products or changes in customer buying patterns could negatively impact our ability to generate funds from operations. Additionally, decreased demand or changes in buying patterns could impact our ability to meet the debt covenants of our credit agreement and, therefore, negatively impact the funds available under our unsecured revolving credit facility. We believe that cash expected to be provided by operating activities and availability under our unsecured revolving credit facility will be sufficient to fund both our short-term and long-term capital and liquidity needs for the foreseeable future. However, there can be no assurance that we will continue to generate cash flows at or above recent levels.

The following table identifies cash provided by/(used in) our operating, investing and financing activities for the three months ended March 31, 2018 and 2017 (in thousands):



	For the Three Months Ended March 31,
Liquidity:	2018			2017
Total cash provided by/(used in):
Operating activities	$	432,277		$	376,700
Investing activities	(114,466		)	(111,023		)
Financing activities	(325,634		)	(384,736		)
Net decrease in cash and cash equivalents	$	(7,823	)	$	(119,059	)

Capital expenditures	$	114,843		$	110,632
Free cash flow ⁽¹⁾	$	311,116		$	242,754


⁽¹⁾	Calculated as net cash provided by operating activities, less capital expenditures and excess tax benefit from share-based compensation payments for the period.

Operating activities:

The increase in net cash provided by operating activities during the three months ended March 31, 2018, compared to the same period in 2017, was primarily due to an increase in net income and a smaller increase in our net inventory investment, partially offset by a smaller benefit from income taxes payable. The smaller increase in our net inventory investment was primarily the result of seasonal fluctuations in inventory levels combined with an increase in accounts payable as a percentage of inventory. The smaller benefit in income taxes payable was primarily driven by a lower provision for income taxes in the current period, as compared to the same period in the prior year, as a result of the lower federal corporate tax rate due to the Tax Act.

Investing activities:

The increase in net cash used in investing activities during the three months ended March 31, 2018, compared to the same period in 2017, was primarily the result of an increase in capital expenditures. The increase in capital expenditures was primarily related to the timing of property acquisitions, closing costs and construction costs for new stores, as compared to the same period in the prior year.

Financing activities:

The decrease in net cash used in financing activities during the three months ended March 31, 2018, compared to the same period in 2017, was primarily attributable to a higher level of net borrowings during the current period, as compared to the same period in the prior year, partially offset by higher repurchases of our common stock during the current period, as compared to the same period in the prior year.

Unsecured revolving credit facility:

On April 5, 2017, the Company entered into a credit agreement (the “Credit Agreement”). The Credit Agreement provides for a five-year $1.20 billion unsecured revolving credit facility (the “Revolving Credit Facility”) arranged by JPMorgan Chase Bank, N.A., which is scheduled to mature in April 2022. The Credit Agreement includes a $200 million sub-limit for the issuance of letters of credit and a $75 million sub-limit for swing line borrowings. As described in the Credit Agreement governing the Revolving Credit Facility, the Company may, from time to time, subject to certain conditions, increase the aggregate commitments under the Revolving Credit Facility by up to $600 million, provided that the aggregate amount of the commitments does not exceed $1.80 billion at any time.

As of March 31, 2018, we had outstanding letters of credit, primarily to support obligations related to workers’ compensation, general liability and other insurance policies, in the amount of $37 million, reducing the aggregate availability under the Credit Agreement by that amount. As of March 31, 2018, we had outstanding borrowings under the Revolving Credit Facility in the amount of $560 million.

Senior Notes:

We have issued a cumulative $2.65 billion aggregate principal amount of unsecured senior notes, which are due between 2021 and 2027, with UMB Bank, N.A. as trustee. Interest on the senior notes, ranging from 3.550% to 4.875%, is payable semi-annually and is computed on the basis of a 360-day year. None of our subsidiaries are guarantors under the Senior Notes.

Debt covenants:

The indentures governing our senior notes contain covenants that limit our ability and the ability of certain of our subsidiaries to, among other things, create certain liens on assets to secure certain debt and enter into certain sale and leaseback transactions, and limit our ability to merge or consolidate with another company or transfer all or substantially all of our property, in each case as set forth in the indentures.

These covenants are, however, subject to a number of important limitations and exceptions. As of March 31, 2018, we were in compliance with the covenants applicable to our senior notes.

The Credit Agreement contains certain covenants, including limitations on indebtedness, a minimum consolidated fixed charge coverage ratio of 2.50:1.00 and a maximum consolidated leverage ratio of 3.50:1.00. The consolidated fixed charge coverage ratio includes a calculation of earnings before interest, taxes, depreciation, amortization, rent and non-cash share-based compensation expense to fixed charges. Fixed charges include interest expense, capitalized interest and rent expense. The consolidated leverage ratio includes a calculation of adjusted debt to earnings before interest, taxes, depreciation, amortization, rent and non-cash share-based compensation expense. Adjusted debt includes outstanding debt, outstanding stand-by letters of credit and similar instruments, five-times rent expense and excludes any premium or discount recorded in conjunction with the issuance of long-term debt. In the event that we should default on any covenant contained within the Credit Agreement, certain actions may be taken, including, but not limited to, possible termination of commitments, immediate payment of outstanding principal amounts plus accrued interest and other amounts payable under the Credit Agreement and litigation from our lenders.

We had a consolidated fixed charge coverage ratio of 5.64 times and 5.98 times as of March 31, 2018 and 2017, respectively, and a consolidated leverage ratio of 2.05 times and 1.56 times as of March 31, 2018 and 2017, respectively, remaining in compliance with all covenants related to the borrowing arrangements.

The table below outlines the calculations of the consolidated fixed charge coverage ratio and consolidated leverage ratio covenants, as defined in the Credit Agreement governing the Revolving Credit Facility, for the twelve months ended March 31, 2018 and 2017 (dollars in thousands):

The table below outlines the calculation of Free cash flow and reconciles Free cash flow to Net cash provided by operating activities, the most directly comparable GAAP financial measure, for the three months ended March 31, 2018 and 2017 (in thousands):



		For the Three Months Ended March 31,

Free cash flow		$	311,116	$	242,754

Free cash flow, the consolidated fixed charge coverage ratio and the consolidated leverage ratio discussed and presented in the tables above are not derived in accordance with United States generally accepted accounting principles (“GAAP”). We do not, nor do we suggest investors should, consider such non-GAAP financial measures in isolation from, or as a substitute for, GAAP financial information. We believe that the presentation of our free cash flow, consolidated fixed charge coverage ratio and consolidated leverage ratio provides meaningful supplemental information to both management and investors and reflects the required covenants under the Credit Agreement. We include these items in judging our performance and believe this non-GAAP information is useful to investors as well. Material limitations of these non-GAAP measures are that such measures do not reflect actual GAAP amounts. We compensate for such limitations by presenting, in the tables above, a reconciliation to the most directly comparable GAAP measures.

Share repurchase program:

In January of 2011, our Board of Directors approved a share repurchase program. Under the program, we may, from time to time, repurchase shares of our 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. Our Board of Directors may increase or otherwise modify, renew, suspend or terminate the share repurchase program at any time, without prior notice. As announced on February 7, 2018, our Board of Directors approved a resolution to increase the authorization amount under our share repurchase program by an additional $1.00 billion, resulting in a cumulative authorization amount of $10.75 billion. The additional authorization is effective for a three-year period, beginning on its announcement date.

The following table identifies shares of our common stock that have been repurchased as part of our publicly announced share repurchase program (in thousands, except per share data):



	For the Three Months Ended March 31,
	2018		2017
Shares repurchased	2,188		1,829
Average price per share	$	251.08	$	268.09
Total investment	$	549,428	$	490,312

As of March 31, 2018, we had $1.17 billion remaining under our share repurchase program. Subsequent to the end of the first quarter and through May 7, 2018, we repurchased 0.5 million additional shares of our common stock under our share repurchase program, at an average price of $238.90, for a total investment of $117 million. We have repurchased a total of 68.9 million shares of our common stock under our share repurchase program since the inception of the program in January of 2011 and through May 7, 2018, at an average price of $140.75, for a total aggregate investment of $9.70 billion.

CONTRACTUAL OBLIGATIONS

There have been no material changes to the contractual obligations, to which we are committed, since those discussed in our Annual Report on Form 10-K for the year ended December 31, 2017.

CRITICAL ACCOUNTING ESTIMATES

The preparation of our financial statements in accordance with GAAP requires the application of certain estimates and judgments by management. Management bases its assumptions, estimates, and adjustments on historical experience, current trends and other factors believed to be relevant at the time the condensed consolidated financial statements are prepared. There have been no material changes in the critical accounting estimates since those discussed in our Annual Report on Form 10-K for the year ended December 31, 2017.

INFLATION AND SEASONALITY

We have been successful, in many cases, in reducing the effects of merchandise cost increases principally by taking advantage of supplier incentive programs, economies of scale resulting from increased volume of purchases and selective forward buying. To the extent our acquisition costs increased due to base commodity price increases industry-wide, we have typically been able to pass along these increased costs through higher retail prices for the affected products. As a result, we do not believe inflation has had a material adverse effect on our operations.

To some extent, our business is seasonal primarily as a result of the impact of weather conditions on customer buying patterns. While we have historically realized operating profits in each quarter of the year, our store sales and profits have historically been higher in the second and third quarters (April through September) than in the first and fourth quarters (October through March) of the year.

RECENT ACCOUNTING PRONOUNCEMENTS

In May of 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standard Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” now codified in the Accounting Standards Codification (“Topic 606”). Under Topic 606, an entity is required to follow a five-step process to determine the amount of revenue to recognize when promised goods or services are transferred to customers. Topic 606 offers specific accounting guidance for costs to obtain or fulfill a contract with a customer. In addition, an entity is required to disclose sufficient information to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. We adopted this guidance using the modified retrospective transition method with our first quarter ended March 31, 2018. Results of the three months ended March 31, 2018, were presented under Topic 606, while amounts in prior periods were not adjusted and continue to be reported under the accounting standard in effect for the prior periods. The adoption of Topic 606 did not have a material impact on our business process, internal controls, systems, consolidated financial condition, results of operations or cash flows; as such, a cumulative effective adjustment was not recorded to opening retained earnings.

In February of 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. We will adopt this guidance beginning with our first quarter ending March 31, 2019. We have established a task force, composed of multiple functional groups inside of the Company, which is currently in the process of evaluating critical components of this new guidance and the potential impact of the guidance on our financial position, results of operations and cash flows. Based on the preliminary work completed, we are considering the potential implications of the new standard on determining the discount rate to be used in valuing new and existing leases, the treatment of existing favorable and unfavorable lease agreements acquired in connection with previous acquisitions, procedural and operational changes that may be necessary to comply with the provisions of the guidance and all applicable financial statement disclosures required by the guidance, all of which are areas that could potentially be impacted by adoption of the guidance. At this time, the task force has not completed its full evaluation; however, we believe the adoption of the new guidance will have a material impact on the total assets and total liabilities reported on our consolidated balance sheets.

In June of 2016, the FASB issued 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. We will adopt this guidance beginning with our first quarter ending March 31, 2020. The application of this new guidance is not expected to have a material impact on our consolidated financial condition, results of operations or cash flows.

In January of 2017, the FASB issued ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). ASU 2017-04 eliminates the second step in the previous process for goodwill impairment testing; instead, the test is now a one-step process that calls for goodwill impairment loss to be measured as the excess of the reporting unit’s carrying amount over its fair value. For public companies, ASU 2017-04 is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period, and requires prospective adoption, with early adoption after January 1, 2017. We will adopt this guidance beginning with our first quarter ending March 31, 2019. The application of this new guidance is not expected to have a material impact on our consolidated financial condition, results of operations or cash flows.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Unless otherwise indicated, “we,” “us,” “our” and similar terms, as well as references to the “Company” or “O’Reilly,” refer to O’Reilly Automotive, Inc. and its subsidiaries.

We are subject to interest rate risk to the extent we borrow against our unsecured revolving credit facility (the “Revolving Credit Facility”) with variable interest rates based on either a Base Rate or Eurodollar Rate, as defined in the credit agreement governing the Revolving Credit Facility. As of March 31, 2018, we had outstanding borrowings under our Revolving Credit Facility in the amount of $560 million, at the weighted-average variable interest rate of 2.784%. At this borrowing level, a 0.25% increase in interest rates would have had an unfavorable annual impact on our pre-tax earnings and cash flows in the amount of $1.4 million.

We invest certain of our excess cash balances in short-term, highly-liquid instruments with maturities of 90 days or less. We do not expect any material losses from our invested cash balances and we believe that our interest rate exposure is minimal. As of March 31, 2018, our cash and cash equivalents totaled $39 million.

Our market risks have not materially changed since those discussed in our Annual Report on Form 10-K for the year ended December 31, 2017.

Item 4. Controls and Procedures

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

As of the end of the period covered by this report, the management of O’Reilly Automotive, Inc. and Subsidiaries (the “Company”), under the supervision and with the participation of its Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to Rule 13a-15(b) and as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended (“the Exchange Act”).

Legal Matters	3 Months Ended

Loss Contingency [Abstract]
Legal matters	NOTE 9 – LEGAL MATTERS 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. As previously reported, on June 18, 2015, a jury in Greene County, Missouri, returned an unfavorable verdict in a litigated contract dispute in the matter Meridian Creative Alliance vs. O’Reilly Automotive Stores, Inc. et. al. in the amount of $12.5 million. As previously reported, the verdict was appealed, reversed in part and remanded to the trial court for a new trial. In the interim period, the matter was resolved at mediation for an amount within the previously reported accrual.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent accounting pronouncements	NOTE 10 - RECENT ACCOUNTING PRONOUNCEMENTS In May of 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standard Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” now codified in the Accounting Standards Codification (“Topic 606”). Under Topic 606, an entity is required to follow a five-step process to determine the amount of revenue to recognize when promised goods or services are transferred to customers. Topic 606 offers specific accounting guidance for costs to obtain or fulfill a contract with a customer. In addition, an entity is required to disclose sufficient information to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted this guidance using the modified retrospective transition method with its first quarter ended March 31, 2018. Results of the three months ended March 31, 2018, were presented under Topic 606, while amounts in prior periods were not adjusted and continue to be reported under the accounting standard in effect for the prior periods. The adoption of Topic 606 did not have a material impact on the Company’s business process, internal controls, systems, consolidated financial condition, results of operations or cash flows; as such, a cumulative effective adjustment was not recorded to opening retained earnings. See Note 6 for information concerning the Company’s revenue recognition policy. In February of 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. The Company will adopt this guidance beginning with its first quarter ending March 31, 2019. The Company has established a task force, composed of multiple functional groups inside of the Company, which is currently in the process of evaluating critical components of this new guidance and the potential impact of the guidance on the Company’s financial position, results of operations and cash flows. Based on the preliminary work completed, the Company is considering the potential implications of the new standard on determining the discount rate to be used in valuing new and existing leases, the treatment of existing favorable and unfavorable lease agreements acquired in connection with previous acquisitions, procedural and operational changes that may be necessary to comply with the provisions of the guidance and all applicable financial statement disclosures required by the new guidance, all of which are areas that could potentially be impacted by adoption of the guidance. At this time, the task force has not completed its full evaluation; however, the Company believes the adoption of the new guidance will have a material impact on the total assets and total liabilities reported on the Company’s consolidated balance sheets. In June of 2016, the FASB issued 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 will adopt this guidance beginning with its first quarter ending March 31, 2020. The application of this new guidance is not expected to have a material impact on the Company’s consolidated financial condition, results of operations or cash flows. In January of 2017, the FASB issued ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). ASU 2017-04 eliminates the second step in the previous process for goodwill impairment testing; instead, the test is now a one-step process that calls for goodwill impairment loss to be measured as the excess of the reporting unit’s carrying amount over its fair value. For public companies, ASU 2017-04 is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period, and requires prospective adoption, with early adoption after January 1, 2017. The Company will adopt this guidance beginning with its first quarter ending March 31, 2019. The application of this new guidance is not expected to have a material impact on the Company’s consolidated financial condition, results of operations or cash flows.

Warranties (Policies)	Mar. 31, 2018
Product Warranties Disclosures [Abstract]
Warranties, policy	The Company provides 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.

Revenue from Contract with Customer [Abstract]
Revenue, policy	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. The Company’s primary source of revenue is derived from the sale of automotive aftermarket parts and merchandise to its customers. 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.
