As of September 30, 2019, our fair value allocation of the assets acquired and liabilities assumed from Fairway is still considered preliminary, pending finalization of tax related matters, and is subject to revision, which may result in adjustments to this allocation. We expect to finalize these amounts as soon as possible but not later than the end of 2019. Our updated preliminary fair value allocation of Fairway as of September 30, 2019 includes property, plant and equipment, intangibles and goodwill of $99,386, $186,130 and $145,258, respectively. During the period ended September 30, 2019, goodwill was adjusted $36,859 due to updates from the original preliminary allocation provided as of December 31, 2018. The updated preliminary allocation resulted in prior and current period changes to depreciation and amortization. These changes were considered immaterial and recorded during the nine months ended September 30, 2019. During the period ended September 30, 2019, assets purchased from Fairway which were initially placed into our taxable REIT subsidiary were transferred to our qualifying REIT subsidiary, as a result the Company wrote off $17,031 in deferred tax liabilities assumed from our purchase.
