During 2022, we expanded our Direct customer business by 73% due in part by acquiring new customers (see Note 2). These customers typically require longer credit terms than traditional CPC based customers. One of these Direct customers was a significant portion, 24.1% of our total revenue, and has stretched its payments to 120 days and beyond. Though the customer is paying amounts due and has significantly reduced the balance since year end, management believed it to be prudent to increase the allowance for doubtful accounts.
