Revenue Recognition:
 
Adoption of ASC Topic 606, 
Revenue from Contracts with Customers - 
On April 1, 2018, the Company adopted ASC Topic 606 using the modified retrospective method. Results for reporting periods beginning after April 1, 2018 are presented under ASC Topic 606, while prior period amounts were not adjusted and continue to be reported in accordance with ASC Topic 605, “Revenue Recognition”. The adoption of ASC Topic 606 had no material impact on our current or previously recorded results of operations.
 
The Company’s primary source of revenue is the sale of safety and security products based upon purchase orders or contracts with customers. Revenue is recognized at a point in time once the Company has determined that the customer has obtained control over the product. Control is typically deemed to have been transferred to the customer when the product is shipped or delivered to the customer. Customers may not return, exchange or refuse acceptance of goods without our approval. Generally, the Company does not grant extended payment terms. Shipping and handling costs associated with outbound freight, after control over a product has transferred to a customer, are accounted for as a fulfillment cost and are recorded in selling, general and administrative expense.
 
The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for products sold. Revenue is recorded at the transaction price net of estimates of variable consideration. The Company uses the expected value method based on historical data in considering the impact of estimates of variable consideration, which may include trade discounts, allowances, product returns (including rights of return) or warranty replacements. Estimates of variable consideration are included in revenue to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur.
 
Disaggregation of Revenue: The Company presents below revenue associated with sales of products acquired from our Hong Kong Joint Venture separately from revenue associated with sales of ground fault circuit interrupters (GFCI’s) and ventilation fans. The Company believes this disaggregation best depicts how our various product lines perform and are affected by economic factors. Revenue recognized by these categories for the fiscal years ended March 31, 2019 and 2018 are as follows:

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
