Our inventories that are valued at the lower of LIFO cost or market reflect a valuation reserve of $468.1 million and $240.4 million at September 30, 2020 and December 31, 2019, respectively. The December 31, 2019 market reserve of $240.4 million was reversed due to the sale of inventory quantities that gave rise to the 2019 reserve. A new market reserve of $468.1 million was established as of September 30, 2020 based on market conditions and prices at that time. The effect of the change in lower of cost or market reserve was a decrease to cost of products sold totaling $62.8 million for the three months ended September 30, 2020 and an increase to cost of products sold totaling $34.1 million for the three months ended September 30, 2019, and an increase to cost of products sold totaling $227.7 million for the nine months ended September 30, 2020 and a decrease to cost of products sold totaling $150.5 million for the nine months ended September 30, 2019.

At September 30, 2020, the LIFO value of inventory, net of the lower of cost or market reserve, was equal to current costs.

In connection with our announcement of the conversion of our Cheyenne Refinery to renewable diesel production, we recorded a reserve of $2.9 million and $9.0 million, for the three and the nine months September 30, 2020, respectively, against our repair and maintenance supplies inventory. This charge was recorded in operating expenses.
