Mobile Security, Inc. (MSI) has been an audit client of Leo & Lee, LLP for the past 12 years. MSI is a small, publicly traded aviation company based in Cleveland, Ohio, where it manufactures high-tech unmanned aerial vehicles (UAV), also known as drones, and other surveillance and security equipment. MSI’s products are primarily used by the military and scientific research institutions, but there is growing demand for UAVs for commercial and recreational use. MSI must go through an extensive bidding process for large government contracts. Because of the sensitive nature of government contracts and military product designs, both the facilities and records of MSI must be highly secured.

MSI is known as being an innovator in the industry and holds 25 patents on its products. One of its older patents is for the Covert Recorder, a listening device for land-line phones. Sales of the Covert Recorder have slowly declined in the last decade, primarily due to increased use of smart phones and other advances in technology. For the last few years, management has debated whether the patent, which currently has a carrying value of $500,000, should be impaired. Management conducted an analysis by estimating the future cash flows that will be generated from sales of the Covert Recorder. Based on the analysis, management believes an impairment loss of $400,000 should be recorded and the patent balance written down for the current year.
