Goodwill GoodwillThe Company performed an annual qualitative assessment of impairment of goodwill as of October 1, 2020 for each of the three reporting units, Mission Solutions, Space Components, and Engineering Services, concluding there was no impairment. The Company also concluded that there were no indicators of goodwill impairment requiring further testing during the three and nine months ended September 30, 2021.

Ending balance of goodwill as of September 30, 2021
$ 69,625 

The Company’s estimate of the amount payable to/receivable from the seller as of the acquisition date changed during the Successor 2021 Period resulting in measurement period adjustments for DSS, MIS, Roccor and DPSS. These changes primarily related to the settlement of net working capital adjustments.

During the Successor 2021 Period, LoadPath finalized its predecessor tax return which included an election for which assets and liabilities are recorded at fair value and no differences between book and tax basis exist at the acquisition date, resulting in a measurement period adjustment to the deferred tax liability recorded at acquisition. Based on the Company's continued refinement of estimates around the LoadPath percentage of completion calculation, during the Successor 2021 Period, the Company recorded a measurement period adjustment to reduce the deferred revenue balance with a corresponding reduction to the goodwill balance as of the acquisition date.

Also during the Successor 2021 Period, the Company continued to refine its estimates around the valuation of intangible assets from the acquisition of Oakman. Based on the fair value methodologies described in Note C, a measurement period adjustment was recognized to reduce the fair value of intangible assets with a corresponding increase in goodwill as of the acquisition date.
