The application and interpretation of applicable state sales tax laws to certain of our products is uncertain. Accordingly, we may be exposed to additional sales tax liability to the extent various state jurisdictions determine that certain of our products are subject to such jurisdictions’ sales tax. We have recorded a liability of $10.0 million as of December 31, 2011, reflecting our best estimate of our potential sales tax liability.

In addition to the above matter, we are involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material effect on our financial position, results of operations or liquidity.
