[1] On December 27, 2017, two of the Company’s wholly-owned subsidiaries, Altisource Solutions S.à r.l. and Altisource Holdings S.à r.l., merged, with Altisource Holdings S.à r.l. as the surviving entity. Altisource Holdings S.à r.l. was subsequently renamed Altisource S.à r.l. The merger is part of a larger subsidiary restructuring plan designed to simplify the Company’s corporate structure, allow it to operate more efficiently and reduce administrative costs. For Luxembourg tax purposes, the merger was recognized at fair value and generated an NOL of $1.3 billion and a deferred tax asset, net of valuation allowance, of $300.9 million as of December 31, 2017. The NOL has a 17 year life. This deferred tax asset was partially offset by the impact of other changes in U.S. and Luxembourg income tax rates of $6.3 million and an increase in certain foreign income tax reserves (and related interest) of $10.5 million. See Note 21.

[2] The sum of quarterly amounts, including per share amounts, may not equal amounts reported for year-to-date periods. This is due to the effects of rounding and changes in the number of weighted average shares outstanding for each period.

[3] During the fourth quarter of 2016, Altisource recorded a litigation settlement loss of $32.0 million in connection with a litigation matter. Also during the fourth quarter of 2016, Altisource recorded an insurance recovery related to this litigation settlement of $4.0 million. See Note 19.

[4] We acquired Granite on July 29, 2016. See Note 5.
