2.    REVENUE RECOGNITION

The Company presents net revenue by geographic area based upon the location of the original equipment manufacturers’ (“OEMs”) headquarters as it believes that doing so best depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. Net revenue by geographic area is as follows (in millions):

The Company’s revenue from external customers is generated principally from the sale of semiconductor products that facilitate various wireless communication applications. Accordingly, the Company considers its product offerings to be similar in nature and therefore not segregated for reporting purposes. Accrued customer liabilities of $40.5 million and $38.5 million have been included in other current liabilities within the consolidated balance sheets as of March 27, 2020, and September 27, 2019, respectively.

Concentrations

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of trade accounts receivable. Trade accounts receivable are primarily derived from sales to electronic component distributors and manufacturers of communication products. The Company performs ongoing credit evaluations of its customers.

At March 27, 2020, and September 27, 2019, the Company's three largest accounts receivable balances comprised 57% and 67%, respectively, of aggregate gross accounts receivable.

Significant portions of the Company's sales are concentrated among a limited number of customers. The duration, severity, and future impact of the COVID-19 pandemic are highly uncertain and could result in significant disruptions to the business operations of the Company's customers. If one or more of these major customers significantly decreased its orders for the Company's products, the Company's business could be materially and adversely affected.
