Key estimates in the accompanying consolidated financial statements include, among others, revenue recognition, allowances for doubtful accounts receivable and product returns, provisions for obsolete inventory, potential impairment of long-lived assets, and deferred income tax asset valuation allowances. Actual results could differ materially from these estimates.</font></p> </div> </div> </div> </div> | |

We outsource the manufacture of </font><font style="font-family: 'Times New Roman'; font-size: 10pt;">all of</font><font style="font-family: 'Times New Roman'; font-size: 10pt;"> our products to third party manufacturers located in Asia. If any of these manufacturers experience difficulties in obtaining sufficient supplies of components, component prices significantly exceeding the anticipated costs, an interruption in their operations, or otherwise suffer capacity constraints, we would experience a delay in production and shipping of these products, which would have a negative impact on our revenues. Should there be any disruption in services due to natural disaster, economic or political difficulties, transportation restrictions, acts of terror, quarantine or other restrictions associated with infectious diseases, or other similar events, or any other reason, such disruption may have a material adverse effect on our business. Operating in the international environment exposes us to certain inherent risks, including unexpected changes in regulatory requirements and tariffs, and potentially adverse tax consequences, which could materially affect our results of operations. Currently, we have no second source of manufacturing for a portion of our products.</font></p> </div> </div> </div> </div> | |
