The loss on extinguishment of debt during the twelve months ended December 31, 2010 relates to the $0.7 million write-off of remaining capitalized debt issuance costs associated with our prior credit facility.
(2) In addition to Adjusted EBITDA, we use a second non-GAAP financial metric that we label "Adjusted Net Income" to evaluate our financial performance. We compute Adjusted Net Income by adjusting net income or net loss to remove tax-effected amortization expense, stock-based compensation and other non-recurring gains and losses and we believe it is an important metric that is useful to our board of directors, management and investors for the following reasons:
- Assets being depreciated will often have to be replaced in the future and Adjusted EBITDA does not reflect any expenditure for these items;
- Adjusted EBITDA does not reflect the significant interest expense, or the payments necessary to service interest payments on our debt;
- Adjusted Net Income provides a meaningful comparison of our operating results over several periods because it removes the impact of income and expense items that are not a direct result of our core operations, such as goodwill and intangible impairments, legal settlements, one-time settlement gains and losses on the early extinguishment of long-term debt; and
- We believe Adjusted Net Income measurements are used by investors as a supplemental measure to evaluate the overall operating performance of companies in our industry.
By providing this non-GAAP financial measure, together with the above reconciliation, we believe we are enhancing investors' understanding of our business and our results of operations, as well as assisting investors in evaluating how well we are executing strategic initiatives.
