The Company also provides wireless communication service for intrusion and fire alarm systems. 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.</div></div><div style="font-family: "times new roman", times, serif; font-size: 10pt; margin-bottom: 0px; margin-top: 0px; margin-right: 0px; background: none;"><div style="white-space: pre-wrap; font-family: "times new roman", times, serif; font-size: 10pt; background: none; color: rgb(0, 0, 0); text-decoration: none; letter-spacing: 0px; top: 0px;;display:inline;"> </div></div><div style="font-family: "times new roman", times, serif; font-size: 10pt; margin-bottom: 0px; margin-top: 0px; text-align: justify; margin-right: 0px;"><div style="font-family: "times new roman", times, serif; font-size: 10pt; background: none; color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">The Company's fiscal year begins on July 1 and ends on June 30. Historically, the end users of the Company's products want to install its products prior to the summer; therefore sales of its products historically peak in the period April 1 through June 30, the Company's fiscal fourth quarter, and are reduced in the period July 1 through September 30, the Company's fiscal first quarter. In addition, demand is affected by the housing and construction markets.</div></div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table> | |

Critical estimates include management's judgments associated with reserves for sales returns and allowances, concentration of credit risk, inventory reserves, intangible assets and income taxes. Actual results could differ from those estimates.</div></div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table> | |

Estimates for sales returns are based on several factors including actual returns and based on expected return data communicated to it by its customers. Accordingly, the Company believes that its historical returns analysis is an accurate basis for its allowance for sales returns. Actual results could differ from those estimates. As a percentage of gross sales, sales returns, rebates and allowances were 8%, and 7% for the fiscal years ended June 30, 2018 and 2017, respectively.</div></div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table> | |
