4. Inventories are stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out method. The components of inventories consist of the following:

	September 30, 2018		December 31, 2017
Finished products	$	144,963	$	107,595
Raw materials		17,797		15,529
	$	162,760	$	123,124

At September 30, 2018 and December 31, 2017, inventory reserve amounted to $1,673 and $3,137, respectively. Included in this change, during the three and nine months ended September 30, 2018, we adjusted our expected future costs for the re-work and released $696 to income as a consequence. As of September 30, 2018, we believe our inventories are valued at lower of cost or net realizable value.

In July 2015, Financial Accounting Standards Board (“FASB”) issued Accounting Standards Codification (“ASU”) 2015-11, Inventory (Topic 330). Topic 330 required an entity to measure inventory at the lower of cost or market, where market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. This ASU limits the scope to inventory that is measured using first-in, first-out (FIFO) or average cost and requires inventory be measured at the lower of costs or net realizable value. The new standard is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company adopted this new standard effective January 1, 2017. There was no impact on this adoption.
