tax expense. The income tax effects of infrequent or unusual items are recognized in the interim period in which they occur. As the fiscal year progresses, we continually refine our estimate based upon actual events and earnings by jurisdiction during the year. This continual estimation process periodically results in a change to our expected effective tax rate for the fiscal year. When this occurs, we adjust the income tax provision during the quarter in which the change in estimate occurs so that the year-to-date provision equals the expected annual rate.

We account for uncertain tax positions in accordance with FIN 48. On a quarterly basis, we reevaluate the probability that a tax position will be effectively sustained and the appropriateness of the amount recognized for uncertain tax positions based on factors including changes in facts or circumstances, changes in tax law, settled audit issues and new audit activity. Changes in our assessment may result in the recognition of a tax benefit or an additional charge to the tax provision in the period our assessment changes. We recognize interest and penalties related to income tax matters in income tax expense.

Other Contingencies

In the ordinary course of business, we are involved in legal proceedings regarding contractual and employment relationships, product liability claims, trademark rights, and a variety of other matters. We record contingent liabilities resulting from claims against us, including related legal costs, when a loss is assessed to be probable and the amount of the loss is reasonably estimable. Assessing probability of loss and estimating probable losses requires analysis of multiple factors, including in some cases judgments about the potential actions of third party claimants and courts. Recorded contingent liabilities are based on the best information available and actual losses in any future period are inherently uncertain. If future adjustments to estimated probable future losses or actual losses exceed our recorded liability for such claims, we would record additional charges as other (expense) income, net during the period in which the actual loss or change in estimate occurred. In addition to contingent liabilities recorded for probable losses, we disclose contingent liabilities when there is a reasonable possibility that the ultimate loss will materially exceed the recorded liability. Currently, we do not believe that any of our pending legal proceedings or claims will have a material impact on our financial position or results of operations.

Quantitative and Qualitative Disclosures about Market Risk

In the normal course of business and consistent with established policies and procedures, we employ a variety of financial instruments to manage exposure to fluctuations in the value of foreign currencies and interest rates. It is our policy to utilize these financial instruments only where necessary to finance our business and manage such exposures; we do not enter into these transactions for speculative purposes.
