The Company believes the complaint is without merit and intends to vigorously defend itself against the allegations. Given the preliminary stage and the inherent uncertainty of the potential outcome of such proceedings, the Company cannot estimate the reasonably possible range of loss at this time. Based on the available information, the Company believes that the low end of the reasonably possible range of loss is zero and, accordingly, no loss accrual has been provided in the Company’s accompanying financial statements.
