Goodwill impaired, method for fair value determination | In calculating the fair value for CTU and AIU, we performed a valuation analysis, utilizing both income and market approaches, in our goodwill assessment process. The following describes the valuation methodologies used to derive the fair value of our reporting units: • Income Approach: To determine the estimated fair value of each reporting unit, we discount the expected cash flows which are developed by management. We estimate our future cash flows after considering current economic conditions and trends, estimated future operating results and capital investments, our views of growth rates and anticipated future economic and regulatory conditions. The discount rate used represents the estimated weighted average cost of capital, which reflects the overall level of inherent risk involved in our future expected cash flows and the rate of return an outside investor would expect to earn. To estimate cash flows beyond the final year of our models, we use a Gordon Growth Model and terminal value approach and incorporate the present value of the resulting terminal value into our estimate of fair value. • Market-Based Approach: To corroborate the results of the income approach described above, we estimate the fair value of our reporting units using several market-based approaches, including the guideline company method, which focuses on comparing our risk profile and growth prospects to select reasonably similar for-profit postsecondary education publicly traded companies. |  |
