We are currently a party to various claims and legal proceedings incidental to the conduct of our business. If management believes that a loss arising from any of these matters is probable and can reasonably be estimated, we will record the amount of the loss, or the minimum estimated liability when the loss is estimated using a range, and no point within the range is more probable than another. As additional information becomes available, any potential liability related to these matters is assessed and the estimates are revised, if necessary. Litigation is subject to inherent uncertainties, and unfavorable rulings could occur and may include monetary damages. If an unfavorable ruling were to occur, there exists the possibility of a material adverse impact on the financial position and results of operations of the period in which any such ruling occurs, or in future periods.
