Fair Value Measurements - Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The authoritative guidance for fair value measurements establishes a three-level hierarchy, which encourages an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of the hierarchy are defined as follows:


•	Level 1 - inputs to the valuation techniques that are quoted prices in active markets for identical assets or liabilities


•	Level 2 - inputs to the valuation techniques that are other than quoted prices but are observable for the assets or liabilities, either directly or indirectly


•	Level 3 - inputs to the valuation techniques that are unobservable for the assets or liabilities

Assets and Liabilities that are Measured at Fair Value on a Recurring Basis

The following table presents the Company’s financial assets measured at fair value on a recurring basis as of November 2, 2018, November 3, 2017, and February 2, 2018. The fair values of these instruments approximated amortized costs.

There were no transfers between Levels 1, 2 or 3 during any of the periods presented.

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.

Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis

During the three and nine months ended November 2, 2018, the Company’s only significant assets or liabilities measured at fair value on a nonrecurring basis subsequent to their initial recognition were certain long-lived assets. During the three and nine months ended November 3, 2017, the Company had no significant measurements of assets and liabilities at fair value on a nonrecurring basis subsequent to their initial recognition.

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 executive management and 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, projections of future profitability and whether it is more likely than not the assets will be disposed of significantly prior to the end of their estimated useful life 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.

In the determination of impairment for operating locations, the Company determined the fair values of individual operating locations using an income approach, which required discounting projected future cash flows. When determining the stream of projected future cash flows associated with an individual operating location, management made assumptions, including highest and best use, incorporating local market conditions and inputs from retail store operations where necessary, and about key variables including the following unobservable inputs: sales growth rates, gross margin, controllable and uncontrollable expenses, and asset residual values. In order to calculate the present value of those future cash flows, the Company discounted cash flow estimates at a rate commensurate with the risk that selected market participants would assign to the cash flows. In general, the selected market participants represented a group of other retailers with a location footprint similar in size to the Company’s.

As part of a strategic reassessment of Orchard Supply Hardware (Orchard), during the three months ended August 3, 2018, it was determined to be more likely than not the assets of Orchard would be sold or otherwise disposed of significantly before the end of their previously estimated useful lives, and therefore, these assets experienced a triggering event and were evaluated for recoverability. Operating locations evaluated for recoverability included all Orchard stores, as well as a distribution facility that services the Orchard stores and a corporate facility. Based on this evaluation of Orchard, certain long-lived assets, including tangible and intangible assets, were written down to their fair value of $284 million resulting in impairment charges of $206 million. These non-cash impairment charges are included in selling, general and administrative expense in the accompanying consolidated statements of current and retained earnings.

During the three months ended November 2, 2018, the company committed to closing 20 U.S. home improvement stores and 31 locations in Canada, including 27 stores, as well as exiting certain immaterial non-core activities within its U.S. home improvement business. As a result of these decisions, the related assets experienced a triggering event and were evaluated for recoverability. Based on this evaluation, certain long-lived assets were written down to their fair value of $81 million resulting in impairment charges of $99 million, with $90 million associated with the location closures and $9 million associated with the exit of non-core activities. These non-cash impairment charges are included in selling, general and administrative expense in the accompanying consolidated statements of current and retained earnings.

In addition, as part of the Company’s strategic reassessment process, during the three months ended November 2, 2018, it was determined to be more likely than not the assets of the Mexico retail operations would be sold or otherwise disposed of significantly before the end of their previously estimated useful lives, and therefore, these assets experienced a triggering event and were evaluated for recoverability. Operating locations evaluated for recoverability included all 13 stores in Mexico, as well as a corporate facility. Based on this evaluation of the Mexico retail operations, certain long-lived assets were written down to their fair value of $107 million resulting in impairment charges of $22 million. These non-cash impairment charges are included in selling, general and administrative expense in the accompanying consolidated statements of current and retained earnings.

See Note 8 for additional information regarding the Company’s decisions to exit its Orchard operations and certain U.S. and Canada locations during the third quarter as part of the Company’s ongoing strategic reassessment of the business.

The following table presents the Company’s non-financial assets measured at estimated fair value on a nonrecurring basis and the resulting long-lived asset impairment losses included in earnings. Because assets subject to long-lived asset impairment are not measured at fair value on a recurring basis, certain fair value measurements presented in the table may reflect values at earlier measurement dates and may no longer represent the fair values at November 2, 2018.



	Fair Value Measurements		Impairment Losses
(In millions)	November 2, 2018		Three Months Ended November 2, 2018			Nine Months Ended November 2, 2018
Assets-held-for-use:
Operating locations	$	473	$	(112	)	$	(329	)

Fair Value of Financial Instruments

The Company’s financial instruments not measured at fair value on a recurring basis include cash and cash equivalents, accounts receivable, short-term borrowings, accounts payable, accrued liabilities and long-term debt and are reflected in the financial statements at cost. With the exception of long-term debt, cost approximates fair value for these items due to their short-term nature. The fair values of the Company’s unsecured notes were estimated using quoted market prices. The fair values of the Company’s mortgage notes were estimated using discounted cash flow analyses, based on the future cash outflows associated with these arrangements and discounted using the applicable incremental borrowing rate.

Carrying amounts and the related estimated fair value of the Company’s long-term debt, excluding capitalized lease obligations, are as follows:



	November 2, 2018				November 3, 2017				February 2, 2018
(In millions)	Carrying Amount		Fair Value		Carrying Amount		Fair Value		Carrying Amount		Fair Value
Unsecured notes (Level 1)	$	14,718	$	14,430	$	14,958	$	15,974	$	14,961	$	15,608
Mortgage notes (Level 2)	6		6		7		7		6		7
Long-term debt (excluding capitalized lease obligations)	$	14,724	$	14,436	$	14,965	$	15,981	$	14,967	$	15,615
