King Supply maintains its internal inventory records using perpetual FIFO, but for financial reporting purposes, reports ending inventory and cost of goods sold using periodic LIFO. At the beginning of the year, the company had a balance of $$37,000$ in its LIFO reserve account. By the end of the year, internal records reveal that FIFO ending inventory is $$51,000$ greater than LIFO ending inventory.

Record the year$-$end adjusting entry for the LIFO reserve.
