EBITDA, adjusted earnings and distributable cash are not recognized measures under Canadian generally accepted accounting principles (GAAP) and do not have standardized meanings prescribed by GAAP. EBITDA is a performance measure used by management to provide an indication of cash available for distribution from ongoing operations prior to debt service, capital expenditures and income taxes and is often used to compare companies and income trusts on the basis of ability to generate cash from ongoing operations. Adjusted earnings is defined as earnings before one-time after tax costs of antitrust investigations and related expenses and goodwill impairment. Adjusted earnings is used by management to evaluate the ongoing profitablity of the Fund by eliminating the effect of these material non-operating costs. Distributable cash is a performance measure used by management as an indicator of funds available for distribution to unitholders in an income trust. Management believes that these are useful supplemental measures that may assist investors in assessing the Fund's financial results.

Investors should be cautioned that EBITDA, adjusted earnings and distributable cash should not be construed as alternatives to earnings, cash from operations or other financial measures determined in accordance with GAAP as indicators of the Fund’s performance. The Fund’s method of calculating EBITDA, adjusted earnings and distributable cash may differ from other companies and income trusts and, accordingly, may not be comparable to measures used by them.
