Significant Transactions | Significant Transactions Sale of OneBeacon On May 2, 2017, OneBeacon Ltd. entered into a definitive agreement to be acquired by Intact in an all-cash transaction for $18.10 per share, or roughly 1.65 x tangible book value. White Mountains owns 75.7% of OneBeacon’s outstanding common shares, representing 96.9% of the voting power as of June 30, 2017. On July 18, 2017, White Mountains voted its shares of OneBeacon Ltd. in favor of the OneBeacon Transaction. White Mountains expects to receive gross proceeds of $1.3 billion from the OneBeacon Transaction, which is expected to close in the third or fourth quarter of 2017 and is subject to regulatory approval and other customary closing conditions. The results of OneBeacon have been presented as discontinued operations in the statement of operations and comprehensive income for all periods and OneBeacon’s assets and liabilities have been presented as held for sale as of June 30, 2017 and December 31, 2016. As the OneBeacon Transaction was set at a fixed price, the results of OneBeacon do not impact White Mountains’s adjusted book value per share including the estimated gain from the transaction between signing and closing. See Note 15 — “Held for Sale and Discontinued Operations”. Sale of Star & Shield On March 7, 2017, White Mountains completed its sale of Star & Shield and its investment in SSIE surplus notes to K2 Insurances LLC.

See Note 15 — “Held for Sale and Discontinued Operations”. Acquisition of Buzzmove On August 4, 2016, White Mountains acquired a 70.9% ownership share in Buzzmove for a purchase price of GBP 6.1 million (approximately $8.1 million based upon the foreign exchange spot rate at the date of acquisition). White Mountains recognized total assets acquired related to Buzzmove of $11.5 million, including $7.6 million of goodwill and $1.1 million of intangible assets, and total liabilities assumed of $0.1 million, reflecting acquisition date fair values.

On October 5, 2016, White Mountains received additional proceeds of $1.2 million following the release of the post-closing purchase price adjustment escrow. White Mountains recorded a $51.9 million gain from the sale of Tranzact in discontinued operations, which included a $30.2 million tax expense for the reversal of a tax valuation allowance that is offset by a tax benefit recorded in continuing operations. See Note 6 — “Income Taxes”. The increase to White Mountains’s book value from the sale of Tranzact was $82.1 million. A reconciliation of the gain reported in discontinued operations to the impact to White Mountains’s book value is as follows:
Gain from sale of Tranzact reported in discontinued operations |  | $ | 51.9 |
Add back reclassification from continuing operations for the release of a tax valuation allowance |  | 30.2 |
Increase to White Mountains’s book value from sale of Tranzact |  | $ | 82.1 |
In the first quarter of 2017, White Mountains recorded a $1.0 million reduction to the gain from sale of Tranzact in discontinued operations as a result of state tax expense. Through July 21, 2016, Tranzact’s results of operations are reported as discontinued operations and assets and liabilities held for sale within White Mountains’s GAAP financial statements. See Note 15 — “Held for Sale and Discontinued Operations”.

The amount paid at closing was based on an estimate of Sirius Group’s closing date tangible common shareholder’s equity. During the third quarter of 2016, there was a final true-up to Sirius Group’s tangible common shareholder’s equity that resulted in a $4.0 million reduction to the gain. During 2016, White Mountains recorded $363.2 million of gain from sale of Sirius Group in discontinued operations and $113.3 million in other comprehensive income from discontinued operations from Sirius Group. During the second quarter of 2017, White Mountains recorded a $0.6 million reduction to the gain from sale of Sirius Group as a result of a change to the valuation of the accrued incentive compensation payable to Sirius Group employees.
