Balance at March 31, 2025 included $9,735 for the Puerto Rico project. Accrued contract costs Accrued contract costs consisted of accrued expenses for contracting a third-party service provider to fulfill repair and maintenance obligations required under a contract with a foreign military for units sold in fiscal 2011. Payments to the service provider will be made annually upon completion of each year of service. The Company is contractually obligated to provide such repair and maintenance services through November 2027. These services are being recorded in cost of revenues to correspond with the revenues for these services. Warranty reserve Changes in the warranty reserve and extended warranty were as follows:

The Company establishes a warranty reserve based on anticipated warranty claims at the time product revenue is recognized. Factors affecting warranty reserve levels include the number of units sold, anticipated cost of warranty repairs and anticipated rates of warranty claims. The Company evaluates the adequacy of the provision for warranty costs each reporting period and adjusts the accrued warranty liability to an amount equal to estimated warranty expense for products currently under warranty.
