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.

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.
