Cost of Revenues	Cost of Revenues Costs associated with subscription and maintenance revenues consist primarily of direct labor, amortization of previously capitalized software development costs, communication costs, data feeds, travel and entertainment, and consulting fees. Previously, cost of revenues in each reporting period was impacted by capitalized costs associated with software development and data center projects, and costs associated with upgrades to PASSUR and SMLAT Systems necessary to make such systems compatible with new software applications (all referred to as “Capitalized Assets”), depreciation of PASSUR and SMLAT Network Systems as well as the ordinary repair and maintenance of existing PASSUR and SMLAT Systems. Additionally, cost of revenues in each previous reporting period was impacted by the number of PASSUR and SMLAT System units added to the PASSUR Network, which included the production, shipment, and installation of these assets (largely installed by unaffiliated outside contractors), which had previously been capitalized to the PASSUR Network. The PASSUR Network was written off as of April 30, 2020, as described in more detail below. In prior periods, the labor and fringe benefit costs of the Company employees involved in creating Capitalized Assets were capitalized, rather than expensed, and amortized over three years, as determined by their projected useful life. The Company did not capitalize any software development costs as well as network and data center costs for any periods subsequent to January 31, 2020. Given business conditions in the aviation industry surrounding the unprecedented COVID-19 pandemic, the Company’s software efforts were concentrated in the areas of maintenance of existing products. As a result of the industry changes in response to the COVID-19 pandemic (described in “Impact of the COVID-19 Pandemic”, below), the corresponding review conducted by the Company during the second quarter of fiscal 2020 and the resultant write-offs taken during fiscal 2020, the Company anticipates that its level of capitalized software development costs, including related amortization of such costs, will continue to decrease in the future.
