As indicated in Note 3, in connection with the adoption of ASC 606, effective January 1, 2018, inventories were reduced by $40.2. In connection with the Cues transaction, we acquired $30.7 of inventories.
Inventories include material, labor and factory overhead costs and are reduced, when necessary, to estimated net realizable values. Certain domestic inventories are valued using the last-in, first-out (“LIFO”) method. These inventories were approximately 45% and 56% of total inventory at December 31, 2018 and 2017, respectively. Other inventories are valued using the first-in, first-out (“FIFO”) method.
