U.S. Federal Income Tax Information Relating to Computer Sciences Corporation’s Distribution of the Common Stock of CSRA, Inc. and Payment of the Special Dividend

On November 27, 2015 (the “Effective Date”), Computer Sciences Corporation (“CSC”) distributed all of the shares of common stock of CSRA, Inc. (“CSRA”), a wholly owned subsidiary of CSC, to CSC shareholders (the “Distribution”). Promptly following the Distribution, on November 30, 2015, CSC and CSRA each paid a concurrent special cash dividend of $2.25 per share and $8.25 per share, respectively, to each holder of CSC common stock that received shares of CSRA common stock as a result of the Distribution (together, the “Special Dividend”). Prior to the Distribution, CSC contributed certain assets and operations relating to CSC’s North American Public Sector segment to CSRA.

The Distribution occurred by way of a pro rata dividend to CSC shareholders of record as of November 18, 2015 (the “Record Date”). Each CSC shareholder was entitled to receive one share of CSRA common stock for every share of CSC common stock held by such shareholder at the close of business on the Record Date. CSC did not distribute any fractional shares to shareholders in the Distribution.

The documentation provided below summarizes certain U.S. federal income tax consequences of the Distribution, as well as provides additional information.
