Management uses economic income and economic net income as financial measures to evaluate the profitability and efficiency of its business model. Economic income and economic net income are not presented in accordance with GAAP. Economic income excludes from income before provision for income taxes:
- the non-cash interest expense associated with the liability for shares subject to mandatory redemption. Upon consummation of the initial public offering, such mandatory redemption obligation terminated and the Company no longer reflects in its financial statements non-cash interest expense or the liability related to such obligation; and
- the reorganization-related share-based compensation, which results in non-cash compensation expense reported over the vesting period. In addition, upon the consummation of the initial public offering, the vesting terms related to the ownership of its employees were modified, including the Company’s named executive officers, other than William Manning. Such individuals were entitled to 15% of their ownership interests upon the consummation of the offering, and 15% of their ownership interests over the subsequent three years. The remaining ownership interests are subject to performance-based vesting over such three-year period. Such new vesting terms will not result in dilution to the number of outstanding shares of the Company’s Class A common stock. As a result of such vesting requirements, the Company will recognize non-cash compensation charges through 2014.
