The $0.2 million increase in the Company's net contract assets from December 31, 2017 to December 29, 2018 was primarily due to our fixed-price contracts with the U.S. government that resulted in revenue recognized in excess of amounts billed and the adoption of Topic 606. The Company recognized revenue of approximately $0.3 million and $0.4 million related to our contract liabilities at December 31, 2017 and January 1, 2017, respectively. The Company did not recognize impairment losses on our contract assets during the years ended December 29, 2018 and December 30, 2017.
