Fair Value Measurements

The carrying values of cash, accounts receivable, accounts payable and accrued expenses approximate the fair values of these instruments due to their short-term nature. The carrying amount for borrowings under the revolving credit facility approximates fair value because of the variable market interest rate charged to the Company for these borrowings. When the Company recognizes impairment on certain of its underperforming stores, the carrying values of these stores are reduced to their estimated fair values.

As of December 31, 2017 and January 1, 2017, the Company’s only significant assets or liabilities measured at fair value on a nonrecurring basis subsequent to their initial recognition were assets subject to long-lived asset impairment related to certain underperforming stores. As discussed in Note 5 to the Notes to Consolidated Financial Statements, the Company estimated the fair values of these long-lived assets based on the Company’s own judgments about the assumptions that market participants would use in pricing the asset and on observable market data, when available. The Company classified these fair value measurements as Level 3 inputs, which are unobservable inputs for which market data are not available and that are developed using the best information available about pricing assumptions used by market participants in accordance with ASC 820, Fair Value Measurement. After the impairment charges, the carrying values of the remaining assets of these stores were not material.

As discussed in Note 4 of the Notes to Consolidated Financial Statements, the Company recorded a goodwill impairment charge of $4.4 million in the fourth quarter of fiscal 2017. The fair value of the Company’s reporting unit was determined using level 3 inputs and valuation techniques discussed in Note 4. There were no goodwill impairment charges recorded in fiscal 2016 or 2015.
