4.    INVENTORY

Typically inventories are stated at the lower of cost (first-in, first-out basis) or market (net realizable value). However, in relation to the Immucor Acquisition on August 19, 2011, and the LIFECODES acquisition on March 22, 2013, fair value adjustments of approximately $24.4 million and $4.5 million, respectively, increased inventory to fair value as of those dates which was greater than replacement cost. As of May 31, 2013, approximately $1.7 million of the fair value adjustment related to the LIFECODES acquisition has been expensed through cost of sales in the fiscal 2013 period. The remaining fair value adjustment is expected to be expensed through cost of sales by the end of the second quarter of fiscal 2014, at which time inventories will again be stated at the lower of cost (first-in, first-out basis) or market (net realizable value). As of May 31, 2012, all of the fair value adjustment related to the Immucor Acquisition had been expensed through cost of sales in the Successor fiscal 2012 period and inventories were again stated at the lower of cost (first-in, first-out basis) or market (net realizable value). The following table is in thousands of dollars:
