Effective January 1, 2017, we changed the inventory basis of SHR to FIFO. We believe that the use of FIFO more accurately reflects current inventory valuation. The drop in crude oil prices over the last several years has caused LIFO value of inventory to be above the FIFO value for each period presented. There was no LIFO reserve in any of the periods in this filing; therefore, no change is reflected in our current statements for the retrospective application.

Prior to this change, the difference between the calculated value of inventory under the FIFO and LIFO bases generated either a recorded LIFO reserve (i.e., where FIFO value exceeds the LIFO value) or an unrecorded negative LIFO reserve (i.e., where LIFO value exceeds the FIFO value). In the latter case, in order to ensure that inventory was reported at the lower of cost or market and in accordance with ASC 330-10, we did not increase the stated value of our inventory to the LIFO value. At December 31, 2016, LIFO value of petrochemical inventory exceeded FIFO; therefore, in accordance with the above policy, no LIFO reserve was recorded.

Inventory serves as collateral for our amended and restated credit agreement. See Note 9.

Inventory included petrochemical products in transit valued at approximately $3.4 million and $2.1 million at June 30, 2017, and December 31, 2016, respectively.

Beginning January 1, 2017, due to the expansion of our plant assets at SHR and TC, we began inventorying spare parts for the repair and maintenance of our plant, pipeline and equipment.
