We account for acquisitions in accordance with ASC 805, “Business Combinations”. The estimated fair values of all assets acquired and liabilities assumed in acquisitions are provisional and may be revised as a result of additional information obtained during the measurement period of up to one year from the acquisition date. See “Note 3. Acquisitions and Investment” of the Notes to Consolidated Financial Statements section in the Fiscal 2019 Form 10-K for information about our prior year acquisitions and investments. For the three and nine months ended June 30, 2020, no changes to our fiscal 2019 provisional fair value estimates of assets and liabilities assumed in acquisitions, where the measurement period was open at the beginning of the fiscal year, have been significant. The measurement periods for all prior acquisitions are closed.

On November 2, 2018, pursuant to the Agreement and Plan of Merger (the “Merger Agreement”), dated as of January 28, 2018, among WRKCo Inc. (formerly known as WestRock Company), which we refer to as “WRKCo”, KapStone Paper and Packaging Corporation (“KapStone”), the Company (formerly known as Whiskey Holdco, Inc.), Whiskey Merger Sub, Inc. and Kola Merger Sub, Inc., the Company acquired all of the outstanding shares of KapStone through a transaction in which: (i) Whiskey Merger Sub, Inc. merged with and into WRKCo, with WRKCo surviving the merger as a wholly owned subsidiary of the Company and (ii) Kola Merger Sub, Inc. merged with and into KapStone, with KapStone surviving the merger as a wholly owned subsidiary of the Company (collectively, the “KapStone Acquisition”). Effective as of the effective time of the KapStone Acquisition (the “Effective Time”), Whiskey Holdco, Inc. changed its name to “WestRock Company” and WRKCo changed its name to “WRKCo Inc.”

KapStone is a leading North American producer and distributor of containerboard, corrugated products and specialty papers, including liner and medium containerboard, kraft papers and saturating kraft. KapStone also owns Victory Packaging, a packaging solutions distribution company with facilities in the U.S., Canada and Mexico. We have included the financial results of KapStone in our Corrugated Packaging segment since the date of the KapStone Acquisition.

Pursuant to the KapStone Acquisition, at the Effective Time, (a) each issued and outstanding share of common stock, par value $0.01 per share, of WRKCo was converted into one share of common stock, par value $0.01 per share, of the Company (“Company common stock”) and (b) each issued and outstanding share of common stock, par value $0.0001 per share, of KapStone (“KapStone common stock”) (other than shares of KapStone common stock owned by (i) KapStone or any of its subsidiaries or (ii) any KapStone stockholder who properly exercised appraisal rights with respect to its shares of KapStone common stock in accordance with Section 262 of the Delaware General Corporation Law) was automatically canceled and converted into the right to receive (1) $35.00 per share in cash, without interest (the “Cash Consideration”), or, at the election of the holder of such share of KapStone common stock, (2) 0.4981 shares of Company common stock (the “Stock Consideration”) and cash in lieu of fractional shares, subject to proration procedures designed to ensure that the Stock Consideration would be received in respect of no more than 25% of the shares of KapStone common stock issued and outstanding immediately prior to the Effective Time (the “Maximum Stock Amount”). Each share of KapStone common stock in respect of which a valid election of Stock Consideration was not made by 5:00 p.m. New York City time on September 5, 2018 was converted into the right to receive the Cash Consideration. KapStone stockholders elected to receive Stock Consideration that was less than the Maximum Stock Amount and no proration was required.

The consideration for the KapStone Acquisition was $4.9 billion including debt assumed, a long-term financing obligation and assumed equity awards. As a result, KapStone stockholders received in the aggregate approximately $3.3 billion in cash and 1.6 million shares of WestRock common stock with a value of $70.1 million, or approximately 0.6% of the issued and outstanding shares of WestRock common stock immediately following the Effective Time. Pursuant to the Merger Agreement, at the Effective Time, the Company assumed any outstanding awards granted under the equity-based incentive plans of WRKCo and KapStone (including the shares underlying such awards), the award agreements evidencing the grants of such awards and, in the case of the WRKCo equity-based incentive plans, the remaining shares available for issuance under the applicable plan, in each case subject to adjustments to such awards in the manner set forth in the Merger Agreement. Included in the consideration was $70.8 million related to outstanding KapStone equity awards that were replaced with WestRock equity awards with identical terms for pre-combination service. The amount related to post-combination service will be expensed over the remaining service period of the awards.

The following table summarizes the fair values of the assets acquired and liabilities assumed in the KapStone Acquisition by major class of assets and liabilities as of the acquisition date, as well as adjustments made during fiscal 2019 and fiscal 2020 (referred to as “measurement period adjustments”) (in millions):

	Amounts Recognized as of the Acquisition Date		Measurement Period Adjustments ⁽¹⁾			Amounts Recognized as of Acquisition Date (as Adjusted)⁽²⁾
Cash and cash equivalents	$	8.6	$	—		$	8.6
Current assets, excluding cash and cash equivalents		878.9		(30.2	)		848.7
Property, plant and equipment, net		1,910.3		11.5			1,921.8
Goodwill		1,755.0		0.5			1,755.5
Intangible assets		1,336.1		30.3			1,366.4
Other long-term assets		27.9		(0.1	)		27.8
Total assets acquired		5,916.8		12.0			5,928.8

Current portion of debt		33.3		—			33.3
Current liabilities		337.5		7.9			345.4
Long-term debt due after one year		1,333.4		—			1,333.4
Accrued pension and other long-term benefits		9.8		2.8			12.6
Deferred income taxes		609.7		(1.4	)		608.3
Other long-term liabilities		118.4		2.7			121.1
Total liabilities assumed		2,442.1		12.0			2,454.1
Net assets acquired	$	3,474.7	$	—		$	3,474.7

The fair value assigned to goodwill is primarily attributable to buyer-specific synergies expected to arise after the KapStone Acquisition (e.g., enhanced geographic reach of the combined organization, increased vertical integration and other synergistic opportunities) and the assembled work force of KapStone, as well as from establishing deferred tax liabilities for the assets and liabilities acquired. The goodwill and intangible assets resulting from the KapStone Acquisition are not amortizable for tax purposes.

The following table summarizes the weighted average life and the fair value of intangible assets recognized in the KapStone Acquisition, excluding goodwill (in millions, except lives):

	Weighted Avg. Life		Gross Carrying Amount
Customer relationships		11.7	$	1,303.0
Trademarks and tradenames		16.9		54.2
Favorable contracts		6.0		9.2
Total		11.9	$	1,366.4

None of the intangible assets have significant residual value. The intangible assets are being amortized over estimated useful lives ranging from one to 20 years based on a straight-line basis because the amortization pattern was not reliably determinable.
