Summary of Significant Accounting Policies
Fair Value Measurements	When available, quoted prices were used to determine fair value. When quoted prices in active markets were available, investments were classified within Level 1 of the fair value hierarchy. When quoted prices in active markets were not available, fair values were determined using pricing models, and the inputs to those pricing models were based on observable market inputs. The inputs to the pricing models were typically benchmark yields, reported trades, broker-dealer quotes, issuer spreads and benchmark securities, among others. The Company reviews the carrying amounts of long-lived assets whenever certain events or changes in circumstances indicate that the carrying amounts may not be recoverable. With input from retail store operations, the Company's accounting and finance personnel that organizationally report to the chief financial officer, assess the performance of retail stores quarterly against historical patterns and projections of future profitability for evidence of possible impairment. An impairment loss is recognized when the carrying amount of the asset (disposal) group is not recoverable and exceeds its fair value. The Company estimated the fair values of assets subject to long-lived asset impairment based on the Company's own judgments about the assumptions that market participants would use in pricing the assets and on observable market data, when available. The Company classified these fair value measurements as Level 3.
Extended Protection Plans	The Company sells separately-priced extended protection plan contracts under a Lowe's-branded program for which the Company is ultimately self-insured. The Company recognizes revenue from extended protection plan sales on a straight-line basis over the respective contract term. Extended protection plan contract terms primarily range from one to four years from the date of purchase or the end of the manufacturer's warranty, as applicable. Incremental direct acquisition costs associated with the sale of extended protection plans are also deferred and recognized as expense on a straight-line basis over the respective contract term. The Company's extended protection plan deferred costs are included in other assets (noncurrent) on the consolidated balance sheets. All other costs, such as costs of services performed under the contract, general and administrative expenses and advertising expenses are expensed as incurred. The liability for extended protection plan claims incurred is included in other current liabilities on the consolidated balance sheets.
