Share Repurchase Program

Our board of directors has authorized a share repurchase program (the "Share Repurchase Program") under which we may purchase up to $600.0 million of our outstanding Common Shares. The Share Repurchase Program does not have a fixed expiration, may be modified, suspended or discontinued at any time and any repurchases made pursuant to the Share Repurchase Program are subject to compliance with applicable covenants and restrictions under our financing agreements.

The following table summarizes shares repurchase, aggregate cost (exclusive of fees) and the average per share price (in millions, except average per share price):
