[1] During the six months ended June 30, 2014, the Company recorded Measurement Period Adjustments (as hereinafter defined) to certain net assets and intangible assets acquired in the Colomer Acquisition (as hereinafter defined) on October 9, 2013. Accordingly, the prior period has been retrospectively adjusted for such Measurement Period Adjustments. Refer to Note 2, "Business Combination" for additional details.

[2] The Company recorded a $3.9 million income tax adjustment to the beginning tax balance within other assets and a $4.8 million adjustment to other long-term liabilities, resulting in a net increase to goodwill of $0.9 million.

[3] The Measurement Period Adjustments to intangible assets, deferred tax liability and goodwill in the first quarter of 2014 related to a change in assumptions used to calculate the fair value of an acquired customer relationship intangible asset, which increased the intangible asset by $5.4 million and extended the life of the asset from 10 to 20 years, increased deferred tax liabilities by $2.1 million, and resulted in a net decrease to goodwill of $3.3 million.
