Acquisitions and Divestitures	Acquisitions and Divestitures Acquisitions As more fully discussed in Note 11 of the Company's notes to the consolidated financial statements in its 2017 Annual Report on Form 10-K, the estimated fair values of the assets acquired and liabilities assumed as part of the AAG acquisition in November 2017 are preliminary and subject to revision, pending completion of the final valuations for these assets.

For the six months ended June 30, 2018, no significant changes were made to the provisional amounts disclosed for the year ended December 31, 2017. Divestitures On April 12, 2018, the Company entered into a definitive agreement with Essendant to combine with the Company's Business Products Group in a business combination transaction. The transaction is structured as a Reverse Morris Trust, in which the Company will separate the Business Products Group into a standalone company and spin off that standalone company to the Company's shareholders, immediately followed by the merger of a subsidiary of Essendant and the spun-off company. Subsequently, Essendant received letters from Staples, Inc. ("Staples") expressing its interest in the purchase of 100% of Essendant's equity for $11.50 per share in cash. Additionally, the Federal Trade Commission has issued second requests in connection with filings under the Hart-Scott-Rodino Antitrust Improvement Act for both the Company's definitive agreement with Essendant and the Staples proposal to acquire Essendant. The proceeds of the transaction will take the form of Essendant shares to be issued at closing to the Company's shareholders plus one-time cash payments to the Company of approximately $347,000, subject to adjustments at closing. Upon closing, the Company's shareholders will own approximately 51% and Essendant shareholders will own approximately 49% of the combined company on a diluted basis, with approximately 80,000,000 diluted shares expected to be outstanding. The spinoff will have no effect on the number of the Company's common shares owned by the Company's shareholders or the number of shares of the Company's common stock outstanding. The transaction is intended to be tax-free to the Company's shareholders for U.S. federal income tax purposes. Subject to regulatory and Essendant shareholder approvals and other customary closing conditions, the Company continues to expect to close on the proposed transaction with Essendant before the end of 2018. The assets and liabilities of the Business Products Group will continue to be presented as "held and used" on the Company's condensed consolidated balance sheet until the closing of the transaction. The spinoff announcement was evaluated and determined not to be an event or a change in circumstance that required a recoverability test or a goodwill impairment assessment. However, an impairment loss could be recognized by the Company at the spinoff date if the aggregate carrying amount of the Business Products Group's assets and liabilities exceeds its aggregate fair value at that date. The Company cannot currently predict whether an impairment loss will be recorded at the spinoff date.

Divestitures

On April 12, 2018, the Company entered into a definitive agreement with Essendant to combine with the Company's Business Products Group in a business combination transaction. The transaction is structured as a Reverse Morris Trust, in which the Company will separate the Business Products Group into a standalone company and spin off that standalone company to the Company's shareholders, immediately followed by the merger of a subsidiary of Essendant and the spun-off company. Subsequently, Essendant received letters from Staples, Inc. ("Staples") expressing its interest in the purchase of 100% of Essendant's equity for $11.50 per share in cash. Additionally, the Federal Trade Commission has issued second requests in connection with filings under the Hart-Scott-Rodino Antitrust Improvement Act for both the Company's definitive agreement with Essendant and the Staples proposal to acquire Essendant.

The proceeds of the transaction will take the form of Essendant shares to be issued at closing to the Company's shareholders plus one-time cash payments to the Company of approximately $347,000, subject to adjustments at closing.

The assets and liabilities of the Business Products Group will continue to be presented as "held and used" on the Company's condensed consolidated balance sheet until the closing of the transaction.
