Although the maximum amount of future payments that the Company could be required to make under these indemnification agreements is unlimited, management believes that the Company maintains adequate levels of insurance coverage to protect the Company with respect to most potential claims arising from such agreements and that such agreements do not otherwise have value separate and apart from the liabilities incurred in the ordinary course of the Company’s business. Thus, no liabilities have been recorded with respect to such indemnification agreements as of May 31, 2017.
