Depreciation of capitalized internal-use software costs included in depreciation expense was $869 and $749 for 1^st Quarter 2017 and 1^st Quarter 2016, respectively.

Depreciation expense was $8,979 and $8,058 for 1^st Quarter 2017 and 1^st Quarter 2016, respectively.

During 1^st Quarter 2017, the Company announced its intention to close one of its manufacturing facilities in Enid, Oklahoma effective May 1, 2017 and relocate the affected employees, production and inventory to another manufacturing facility. In connection with the announcement, the Company assessed the net book value of the long-lived assets held at this facility for recoverability and concluded that the carrying amount was recoverable. The net book value of long-lived assets at the facility was $1,592 at April 1, 2017. Fair values were determined using level 3 inputs as defined by ASC 820. Unobservable inputs were developed based on the best estimates available, including the Company’s projections of future cash inflows and outflows and an independent appraisal of the land and building.
