Second Amendment to Amended and Restated Credit and Guaranty Agreement

On April 19, 2013, we executed a second amendment to our Amended and Restated Credit and Guaranty Agreement entered into as of August 16, 2011. The second amendment (i) removes limits on our ability to conduct a share repurchase program so long as we remain in compliance with certain existing financial covenants; (ii) increases the income we may receive from leases and subleases; (iii) increases the amount of debt we may assume in connection with acquisitions; and (iv) increases our ability to invest in Canada and the United Kingdom. This amendment in and of itself does not have a material financial effect.

Share Repurchase Program

In April, our Board of Directors authorized a new share repurchase program, authorizing us to repurchase up to $125.0 million of our common shares from time to time in open market purchases, pursuant to trading plans established in accordance with SEC rules or through privately negotiated transactions. The extent and timing of our repurchases will depend upon market conditions, our cash requirements to fund the long-term growth investments in our business and other corporate considerations. The repurchases will be funded by existing cash balances and by our revolving credit facility. The share repurchase program has no expiration date. The repurchase program may be suspended or discontinued at any time.
