Use of Non-GAAP Financials

The Company refers to the non-GAAP financial measures cited above in making operating decisions because they provide meaningful supplemental information regarding the Company’s ongoing operational performance. Non-GAAP net income excludes stock-based compensation expenses, executive separation costs, in connection with our follow-on offering, expenses in relation to flood, and expenses related to reduction in workforce. We have excluded these items in order to enhance investors’ understanding of our ongoing operations. The use of these non-GAAP financial measures has material limitations because they should not be used to evaluate our company without reference to their corresponding GAAP financial measures. As such, we compensate for these material limitations by using these non-GAAP financial measures in conjunction with GAAP financial measures.

These non-GAAP financial measures are used to: (1) measure company performance against historical results, (2) facilitate comparisons to our competitors’ operating results, and (3) allow greater transparency with respect to information used by management in financial and operational decision making. In addition, these non-GAAP financial measures are used to measure company performance for the purposes of determining employee incentive plan compensation.
