Inventories, which are valued at the lower of LIFO cost or market, reflect a valuation reserve of $480.9 million and $397.5 million at September 30, 2015 and December 31, 2014, respectively. The December 31, 2014 market reserve of $397.5 million was reversed due to the sale of inventory quantities that gave rise to the 2014 reserve. A new market reserve of $480.9 million was established as of September 30, 2015 based on market conditions and prices at that time. The effect of the change in lower of cost or market reserve was a $225.5 million and $83.4 million increase to cost of products sold for the three and nine months ended September 30, 2015, respectively.
