[1] 2014 reorganization activities related to discontinued operations included elimination of 30 positions in the U.S. and Sweden as well as lease termination payments for offices in the U.S. and the U.K.

[2] As a result of the divestiture of the Company's Legal eDiscovery business in the fourth quarter of 2014, the Company recorded impairment charges related to assets no longer in use of $467 in the U.S. and U.K.

[3] Income tax expense is provided at the effective tax rate by taxing jurisdiction and differs from the U.S. statutory tax rate of 35% due to the inability of the Company to recognize tax benefits on losses in the U.S. and certain foreign jurisdictions, variations from the U.S. tax rate in foreign jurisdictions, non-deductible expenses and other miscellaneous taxes.

[4] As of December 31, 2014, other assets from Legal eDiscovery consisted primarily of estimated customary working capital adjustments in connection with the sale of the Legal eDiscovery business.
