[1] See Note 1 for restatement information. [2] Certain amounts have been adjusted to reflect measurement period adjustments related to the CSI acquisition (see Note 2). [3] Certain amounts have been reclassified to reflect a change in accounting principle (see Note 1). [4] Sums may not total due to rounding. [5] The Company had 0.6 million shares represented by options for the twelve months ended March 31, 2014, which were not included in the computation of average dilutive shares outstanding because they were anti-dilutive. In periods with a net loss from continuing operations, the basic loss per share equals the diluted loss per share as all common stock equivalents are excluded from the per share calculation.
