Litigation

From time to time, the Company is a party to legal proceedings in the course of its business, including the matters described below. The outcome of any such legal proceedings, regardless of the merits, is inherently uncertain. In addition, litigation and related matters are costly and may divert the attention of our management and other resources that would otherwise be engaged in other activities. If the Company were unable to prevail in any such legal proceedings, its business, results of operations, liquidity and financial condition could be adversely affected. The Company recognizes accruals for litigations to the extent that it can conclude that a loss is both probable and reasonably estimable and recognizes legal expenses as incurred.
