In the second quarter of fiscal year 2018, the Company announced its decision to relocate its Duarte, California operations to the Company’s newly renovated Drake Campus in Fort Collins, Colorado, and in fiscal year 2019, Woodward finalized the relocation. On December 30, 2019 the Company closed on the sale of one of two parcels of real property at Woodward’s former Duarte operations and recorded a pre-tax gain on sale of assets of $13,522 (see Note 18, Other (income) expense, net). The carrying value of the remaining parcel of Duarte real property is $2,520 as of March 31, 2020, all of which the Company has identified as an asset held for sale and is included in “Land and land improvements”. The asset held for sale is included in unallocated corporate property, plant, and equipment. Based on an existing real property purchase agreement and current market conditions, the Company expects to record an additional gain on the subsequent sale of the remaining parcel of real property, which is expected to close by September 30, 2020. The Company assessed whether the decision to relocate from its Duarte facility could indicate a potential impairment of the assets at the Duarte facility and concluded that the assets were not impaired as of March 31, 2020 and September 30, 2019.

In the first quarter of fiscal year 2020, Woodward determined that the approved plan to divest of the disposal groups (see Note 10, Impairment of assets held for sale) represented a triggering event requiring the long-lived assets attributable to the disposal groups be assessed for impairment. Given the facts and circumstances at that time, Woodward determined that the remaining value of the plant, property and equipment of the disposal groups was not recoverable and a $13,813 non-cash impairment charge was recorded during the six-months ended March 31, 2020.

For the three and six-months ended March 31, 2020 and 2019, Woodward had depreciation expense as follows:
