We are from time to time involved in various legal proceedings incidental to the conduct of our business, including claims by customers, landlords, employees or former employees. Once it becomes probable that we will incur costs in connection with a legal proceeding and such costs can be reasonably estimated, we establish appropriate reserves. While legal proceedings are subject to uncertainties and the outcome of any such matter is not predictable, we are not aware of any legal proceedings pending or threatened against us that we expect to have a material adverse effect on our financial condition, results of operations or liquidity. ​
