[1] (a) As previously reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.

[2] (b) The measurement period adjustments are related to 1) certain working capital adjustments to reflect facts and circumstances existing as of the acquisition date and; 2) adjustments related to deferred taxes to reflect the allocation of assets and liabilities to various legal entities. These adjustments did not have a significant impact on the Company’s previously reported consolidated financial statements and accordingly, the Company has not retrospectively adjusted those financial statements.
