The accounts receivable turnover measures how frequently during the year the accounts receivable are being converted to cash.
A high ratio implies either that a company operates on a cash basis or that its extension of credit and collection of accounts receivable is efficient.
A low ratio implies the company should re-assess its credit policies in order to ensure the timely collection of imparted credit that is not earning interest for the firm. (VERIZON)

(Even though Verizon has more working capital than ATT, both companies don’t need high working capital because they have high inventory turns and do business on a cash basis. These types of businesses raise money every time they open their doors, then turn around and plow that money back into inventory to increase sales. Since cash can be raised so quickly, there is no need to have a large amount of working capital available.)
