Adjusted Earnings before Interest, Taxes, Depreciation and Amortization (Adjusted EBITDA)
EBITDA is net income (loss), including that net income (loss) related to the non-controlling interest and interest income excluding interest expense, income taxes, depreciation and amortization. EBITDA represents Capstone’s continuing capacity to generate income from operations before taking into account management’s financing decisions and costs of consuming tangible capital assets and intangible assets, which vary according to their vintage, technological currency, and management’s estimate of their useful life.

Adjusted EBITDA is calculated as revenue less operating and administrative expenses plus interest income and dividends or distributions received from equity accounted investments. Amounts attributed to any non-controlling interest are deducted. Adjusted EBITDA for the investment in Bristol Water is included at Capstone’s proportionate ownership interest. Adjusted EBITDA is reconciled to EBITDA by removing equity accounted income, other gains and losses (net), foreign exchange gains and losses, and adding in dividends or distributions from equity accounted investments.

Adjusted Funds from Operations (AFFO)
Capstone’s definition of AFFO measures cash generated by its infrastructure business investments that is available for dividends and general corporate purposes. For wholly owned businesses, AFFO is equal to Adjusted EBITDA less interest paid, repayment of principal on debt, income, taxes paid and maintenance capital expenditures. For businesses that are not wholly owned, the cash generated by the business is only available to Capstone through periodic dividends. For these businesses, AFFO is equal to distributions received. Also deducted are corporate expenses and dividends on preferred shares.
