The number of CSC options was converted at a ratio of 1.0731 to 1. The exercise price of CSC options was converted at a ratio of 0.4486 to 1 resulting in an adjustment of the exercise price from $27.36 to $12.28. CSRA options were granted at a ratio of 1.2666 for every 1 CSC option held, and the exercise price of CSRA options was calculated at a ratio of 0.4510 to 1 resulting in an exercise price of $12.34.
