On the Merger Date, we completed our business combination with GulfMark pursuant to the Agreement and Plan of Merger, dated July 15, 2018 (the “business combination”). The business combination was effected through a two-step reverse merger, pursuant to which (i) Gorgon Acquisition Corp., a Delaware corporation and wholly-owned subsidiary, merged with and into GulfMark, with GulfMark continuing as the surviving corporation and a wholly-owned subsidiary and then, immediately afterwards, (ii) GulfMark merged with and into Gorgon NewCo, LLC, a Delaware limited liability company and wholly-owned subsidiary (“Gorgon”), with Gorgon continuing as the surviving entity and a direct, wholly-owned subsidiary. GulfMark’s results are included in our consolidated results beginning on the Merger Date.

Revenues of GulfMark from the Merger Date included in our consolidated statements of operations were $12.7 million for the year ended December 31, 2018. The net loss of GulfMark from the Merger Date was $30.6 million for the year ended December 31, 2018.

Upon completion of the business combination, GulfMark shareholders received 1.10 (the “Exchange Ratio”) shares of Tidewater common stock in exchange for each share of GulfMark owned. Outstanding GulfMark Creditor Warrants (“GLF Creditor Warrants”) and GulfMark Equity Warrants (“GLF Equity Warrants”) were assumed from GulfMark with each warrant becoming exercisable for 1.10 shares of Tidewater common stock on substantially the same terms and conditions as provided in the warrant agreements governing the GLF Creditor Warrants and the GLF Equity Warrants. All outstanding GulfMark restricted stock units (awards granted to GulfMark directors and management prior to the merger) were converted into substantially similar awards to acquire Tidewater common stock with the number of restricted stock units being adjusted by the Exchange Ratio. The fair value of the Tidewater common stock and warrants issued as part of the consideration paid for GulfMark was determined based on the closing price of Tidewater’s common stock on the New York Stock Exchange on November 14, 2018.

Upon consummation of the business combination, we utilized cash from GulfMark and cash on hand to repay the $100 million outstanding balance of GulfMark’s term loan facility. The total purchase consideration for this business combination was $385.5 million.

Assets acquired and liabilities assumed in the business combination have been recorded at their estimated fair values as of the Merger Date under the acquisition method of accounting. The estimated fair values of certain assets and liabilities including long-lived assets and contingencies require judgments and assumptions. There were no adjustments to the original fair value estimates during the measurement period subsequent to the Merger Date.

Upon consummation of the business combination, the $100.0 million GulfMark term loan was repaid. The amounts for assets acquired and liabilities as of the Merger Date were as follows:

	Estimated Fair
(In thousands)	Value
Assets:
Current assets	$	77,942
Property and equipment		360,701
Other assets		779
Liabilities:
Current liabilities		33,881
Long term debt		100,000
Other liabilities		20,049
Net assets acquired	$	285,492

Business combination related costs were expensed as incurred and consisted of various advisory, legal, accounting, valuation and other professional fees totaling $9.0 million for the year ended December 31, 2018. These costs are included in general and administrative expense in our consolidated statement of operations.

Property and equipment acquired in the business combination consisted primarily of 65 offshore support vessels. We recorded property and equipment acquired at its estimated fair value of approximately $361.0 million. The fair values of the offshore support vessels were estimated by applying an income approach, using projected discounted cash flows or a market approach. We estimate the remaining useful lives for the GulfMark fleet, which ranged from 1 to 18 years based on an original estimated useful life of 20 years.

The business combination was executed through the acquisition of GulfMark’s outstanding common stock and therefore the historical tax bases of the acquired assets and assumed liabilities, net operating losses and other tax attributes of GulfMark were assumed at the Merger Date. However, adjustments to the deferred tax assets and liabilities for the tax effects of the difference between the acquisition date fair values and the tax bases of assets acquired and liabilities assumed were nearly completely offset by valuation allowances which resulted in only a minor change to the net deferred tax accounts of GulfMark.

The following unaudited supplemental pro forma results present consolidated information as if the business combination was completed on August 1, 2017. The pro forma results include, among others, (i) a reduction in depreciation expense for adjustments to property and equipment and (ii) a reduction in interest expense resulting from the extinguishment of the GulfMark Term Loan Facility. The pro forma results do not include any potential synergies or non-recurring charges that may result directly from the business combination.
