Inventory	11. Inventory At February 29, 2020 and March 2, 2019, inventories were $539,640 and $604,444, respectively, lower than the amounts that would have been reported using the first-in, first-out (“FIFO”) cost flow assumption. The Company calculates its FIFO inventory valuation using the retail method for store inventories and the cost method for distribution facility inventories. The Company recorded a LIFO credit for fiscal year 2020 of $64,804, compared to a LIFO charge of $23,354 for fiscal year 2019 and a LIFO credit of $28,827 for fiscal year 2018. During fiscal 2020, 2019 and 2018, a reduction in non-pharmacy inventories resulted in the liquidation of applicable LIFO inventory quantities carried at lower costs in prior years. This LIFO liquidation resulted in a $14,449, $5,884 and $2,707 cost of revenues decrease, with a corresponding reduction to the adjustment to LIFO for fiscal 2020, fiscal 2019 and fiscal 2018, respectively.
