Bond commitments. In the ordinary course of business, predominantly in the Company’s Architectural Services business, the Company is required to provide surety or performance bonds that commit payments to its customers for any non-performance by the Company. At May 31, 2014, $81.6 million of the Company’s backlog was bonded by performance bonds with a face value of $278.1 million. Performance bonds do not have stated expiration dates, as the Company is released from the bonds upon completion of the contract. The Company has never been required to make any payments related to these performance bonds with respect to any of the current portfolio of businesses. Warranties. The Company accrues for warranty and claim costs as a percentage of sales based on historical trends and for specific sales credits as they become known and estimable. Actual warranty and claim costs are deducted from the accrual when paid. Factors that could have an impact on the warranty accrual in any given period include the following: changes in manufacturing quality, shifts in product mix and any significant changes in sales volume. The Company’s warranty and claim accruals are detailed below.

Letters of credit. At May 31, 2014, the Company had ongoing letters of credit related to its construction contracts and certain industrial revenue bonds. The total value of letters of credit under which the Company was obligated as of May 31, 2014 was approximately $23.5 million, all of which have been issued under the credit facility. The Company’s total availability under its $100.0 million credit facility is reduced by borrowings under the facility and also by letters of credit issued under the facility. Purchase obligations. The Company has purchase obligations for raw material commitments and capital expenditures. As of May 31, 2014, these obligations totaled $85.2 million. Litigation. The Company is a party to various legal proceedings incidental to its normal operating activities. In particular, like others in the construction supply and services industry, the Company’s construction supply and services businesses are routinely involved in various disputes and claims arising out of construction projects, sometimes involving significant monetary damages or product replacement. The Company is subject to litigation arising out of employment practices, workers compensation, general liability and automobile claims. Although it is very difficult to accurately predict the outcome of such proceedings, facts currently available indicate that no such claims will result in losses that would have a material adverse effect on the results of operations, cash flows or financial condition of the Company.
