Inventories

Inventories, which consist of merchandise and fuel, are stated at the lower of cost or market. For

fuel, cost is determined through the use of the first$-$in$,$ first$-$out $($FIFO$)$ method. For merchandise

inventories, cost is determined through the use of the last$-$in$,$ first$-$out $($LIFO$)$ method. The excess of

replacement cost over the stated LIFO value was $$87,546$ and $$80,814$ at April $30,2020$ and $2019,$

respectively. There were no material LIFO liquidations during the period presented. Below is a
