Line of Credit

We have available for use a credit line of $50.0 million in the United States. As of March 31, 2013, we had no borrowings outstanding on the line of credit. The credit line bears interest at the bank’s base rate and requires us, upon utilization of the credit line, to meet certain financial covenants with respect to limitations on losses. In the event the covenants are not met, the lender may require us to provide collateral to secure the outstanding balance. At March 31, 2013, we were in compliance with the covenants.

Litigation

We are involved in a variety of claims, demands, suits, investigations and proceedings that arise from time to time relating to matters incidental to the ordinary course of our business, including actions with respect to contracts, intellectual property, product liability, employment, benefits and securities matters. As required by authoritative guidance, we have estimated the amount of probable losses that may result from all currently pending matters, and such amounts are reflected in our consolidated financial statements. These recorded amounts are not material to our consolidated financial position or results of operations and no additional material losses related to these pending matters are reasonably possible. While it is not possible to predict the outcome of these matters with certainty, we do not expect the results of any of these actions to have a material adverse effect on our business, results of operations or financial condition. Because litigation is inherently unpredictable, however, the actual amounts of loss may prove to be larger or smaller than the amounts reflected in our consolidated financial statements, and we could incur judgments or enter into settlements of claims that could adversely affect our operating results or cash flows in a particular period.
