Non-GAAP Financial Measures

In April 2007, TSX Group began to bill Toronto Stock Exchange customers for initial and additional listing fees. Prior to this date, these fees were paid upon the listing or reserving of securities which is still the practice on TSX Venture Exchange. With the adoption of a new system, there is now a lag between when securities are issued or reserved and when these listing fees are paid for Toronto Stock Exchange listed issuers. In order to reflect this change, we have adopted the terms issuer services fees billed, initial listing fees billed and additional listing fees billed. These terms replace “listing fees received”, “initial listing fees received” and “additional listing fees received”, which have been used in previous financial reporting. The composition of these measures, however, is unchanged.

Certain measures used in this MD&A, specifically issuer services fees billed, initial listing fees billed, additional listing fees billed and total revenue based on initial and additional listing fees billed do not have standardized meanings prescribed by Canadian GAAP and therefore are unlikely to be comparable to similar measures presented by other issuers. We present these measures as an indication of how initial and additional listing activity and the fees billed for listing or reserving securities, impact the financial performance and cash flows of our business. Management uses these measures to assess the effectiveness of our strategy to serve our listed issuers and grow the listings portion of our business.

We present earnings per share prior to a reduction in the value of the future tax asset as an indication of operating performance exclusive of tax charges, which primarily relate to lower federal corporate income tax rates and other adjustments. This measure is unlikely to be comparable to similar measures presented by other issuers. Management uses this measure to assess financial performance excluding non-cash items such as the reduction of the future tax asset.
