Voluntarily Delist from Toronto Stock Exchange

The Company has provided written notice to the Toronto Stock Exchange (“TSX”) regarding the delisting of its common stock. The Company anticipates that its common stock will be delisted from the TSX at the close of trading on June 24, 2013. The Company believes that the minimal trading volume of its shares on the TSX no longer justifies the expenses and administrative efforts associated with maintaining this dual listing. The Company’s listing with NASDAQ provides its shareholders with sufficient liquidity, as NASDAQ accounts for nearly all of the Company’s current trading volume. Further, administrative and regulatory efficiencies will be achieved by focusing on the single listing. The Company’s common stock will continue to be listed and trade on NASDAQ and its Canadian shareholders will be able to continue to trade through their brokers on that market.

Non-GAAP Financial Measure

Constant-dollar net revenue changes, which exclude the impact of changes in foreign exchange rates, is not a United States Generally Accepted Accounting Principle (“GAAP”) performance measure. We provide constant-dollar net revenue changes because we use the measure to understand the underlying growth rate of revenue excluding the impact on a quarter-by-quarter basis of changes in foreign exchange rates, which are not under management’s direct control. We believe that disclosing net revenue changes on a constant-dollar basis is useful to investors because it enables them to better understand the level of growth of our business.
