Inventory under inventory supply and intermediation arrangements included certain crude oil stored at the Company's Delaware City refinery's storage facilities that the Company was obligated to purchase as it was consumed in connection with its Crude Supply Agreement that expired on December 31, 2015; and light finished products sold to counterparties in connection with the A&R Intermediation Agreements and stored in the Paulsboro and Delaware City refineries' storage facilities.

Due to the lower crude oil and refined product pricing environment beginning at the end of 2014 and continuing throughout 2015 and 2016, the Company recorded adjustments to value its inventories to the lower of cost or market. During the year ended December 31, 2016, the Company recorded an adjustment to value its inventories to the lower of cost or market which increased both operating income and net income by $521,348 reflecting the net change in the lower of cost or market inventory reserve from $1,117,336 at December 31, 2015 to $595,988 at December 31, 2016. During the year ended December 31, 2015, the Company recorded an adjustment to value its inventories to the lower of cost or market which decreased both operating income and net income by $427,226 reflecting the net change in the lower of cost or market inventory reserve from $690,110 at December 31, 2014 to $1,117,336 at December 31, 2015.

An actual valuation of inventories valued under the LIFO method is made at the end of each year based on inventory levels and costs at that time. We recorded a charge related to a LIFO layer decrement of $11,746 during the year ended December 31, 2016. No such LIFO decrement was recorded in the year ended December 31, 2015.
