Depreciation expense was $37.1 million, $31.6 million and $29.8 million in fiscal 2018, 2017 and 2016, respectively. As previously announced, as a result of our investments in productivity and increased capabilities which have led to increased capacity, we closed our St. George, UT architectural glass manufacturing facility in March 2018. As a result of the closure, at year-end, the land and building have been classified as available-for-sale and are carried at estimated fair value within property, plant and equipment on our consolidated balance sheets.
