Impaired long-lived assets held and used, method for determining fair value	Long-lived assets are measured at fair value on a non-recurring basis for purposes of calculating impairment using the fair value hierarchy of ASC Topic No. 820 “Fair Value Measurements” (Topic No. 820). Refer to Note 16, “Fair Value of Financial Instruments,” for further discussion of the Company’s fair value hierarchy. The fair value of the Company’s long-lived assets is calculated using a discounted cash-flow model that used level 3 inputs. In calculating future cash flows, the Company makes estimates regarding future operating results based on its experience and knowledge of market factors in which the retail location is located.
