We offer a diversified array of security products, encompassing access control systems, door-locking products, intrusion and fire alarm systems and video surveillance products. These products are used for commercial, residential, institutional, industrial and governmental applications, and are sold worldwide principally to independent distributors, dealers and installers of security equipment. We have experienced significant growth in recent years, primarily driven by fast growing recurring service revenues generated from wireless communication services for intrusion and fire alarm systems, as well as our school security products that are designed to meet the increasing needs to enhance school security as a result of on-campus shooting and violence in the U.S. </p>

We continuously evaluate our estimates and judgments based on historical experience, as well as other factors that we believe to be reasonable under the circumstances. The results of our evaluation form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Critical estimates include management’s judgments associated with reserves for sales returns and allowances, allowance for credit losses, overhead expenses applied to inventory, inventory reserves, valuation of intangible assets, share based compensation and income taxes. These estimates may change in the future if underlying assumptions or factors change, and actual results may differ from these estimates.</p>
