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, costs associated with upgrades to PASSUR and Surface Multilateration (“SMLAT”) Systems necessary to make such systems compatible with new software applications (all referred to as “Capitalized Assets”), depreciation of PASSUR and SMLAT 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 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. Certain of PASSUR’s services have traditionally relied on our proprietary network of sensors for aircraft surveillance - the PASSUR and SMLAT Network Systems (both collectively, the “PASSUR Network”). During the second quarter of fiscal year 2020, in light of the FAA's mandate for ADS-B equipage on aircrafts operating in most U.S. airspace, effective January 2020, and parallel adoption of ADS-B requirements in much of the world, the Company performed a comprehensive review of its data feeds, specifically those associated with the PASSUR Network units, and external ADS-B data feeds to determine if these external data feeds provide sufficient redundant data as to that generated from the existing PASSUR installations. The Company determined that such services could be powered by a combination of FAA data plus commercial ADS-B aggregator feeds and other data feeds available to the Company, which would provide a more cost-effective solution and allow us to focus more on value-added analytics, and less on sensor technology. In this regard, the Company reviewed and decommissioned approximately half of its PASSUR Network system assets during the second quarter of fiscal 2020. As a result, during the year ended October 31, 2020, the Company wrote off the carrying value applicable to the PASSUR Network systems of approximately $3,565,000, and lease assets applicable to these PASSUR locations of approximately $175,000 during the second quarter of fiscal 2020, which amounts were included as an impairment charge for the year ended October 31, 2020. The write-off amount included PASSUR System and SMLAT System assets as well as inventory of finished and spare parts. Additionally, due to the financial and economic hardships being experienced by the Company’s customers and air transportation support vendors in the current COVID-19 environment, there has been a sufficient amount of uncertainty surrounding the ability of our customers to either renew and/or maintain their current levels of committed contracts with the Company. As a result, during the second quarter of fiscal year 2020, the Company conducted a review of its customer contracts to determine whether an impairment had occurred. In order to determine whether or not an impairment had occurred, we looked at existing contracted revenue, adjusted for future uncertainties, and compared those amounts with the net carrying value of the related software development asset. Where the contracted revenue amount was less than the net carrying value of the software development asset, we noted an impairment. As a result, the Company wrote off previously capitalized software development costs totaling approximately $6,134,000 due to impairment during fiscal 2020. The amount of these charges and write-offs were included as an impairment charge for the year ended October 31, 2020 totaling $9,874,000. 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 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 decrease in the future.

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.
