Policies
Long-lived Assets	Long-Lived Assets The Company reviews long-lived assets for impairment when circumstances indicate the carrying amount of an asset may not be recoverable. Impairment is recognized to the extent the sum of undiscounted estimated future cash flows expected to result from the use of the asset is less than the carrying value. Assets to be disposed of are carried at the lower of their carrying value or fair value, less costs to sell. The Company evaluates the periods of amortization continually in determining whether later events and circumstances warrant revised estimates of useful lives. If estimates are changed, the unamortized costs will be allocated to the increased or decreased number of remaining periods in the asset’s revised life. During the fiscal year ended October 31, 2018, the Company recorded approximately $230,000, $510,000 and $960,000, a total of $1,700,000, of costs associated with an increase in the provision for obsolete and slow moving PASSUR Network parts and supplies, an impairment charge and write-off of carrying amounts related to certain PASSUR Network systems, and capitalized software development costs, respectively. Please refer to footnotes below for further details. The Company did not have any additions to inventory reserves, impairment charges, or write-offs during the fiscal year ended October 31, 2017.
