[1] Due to the use of weighted average shares outstanding when calculating earnings per share, the sum of the quarterly per share data may not equal the per share data for the year.

[2] In periods where convertible debt instruments are dilutive to earnings per share the “if-converted” method of computing diluted EPS requires an interest expense adjustment, net of tax, to net income available to shareholders. The interest expense adjustment was not tax effected for all 2014 periods presented due to our valuation allowance on deferred tax assets. See Note 3 – “Summary of Significant Accounting Policies” for further discussion.
