We sell products worldwide, on credit terms on an unsecured basis, as an OEM supplier, to independent medical supply distributors and directly to the end customer. The manufacturers and distributors, in turn, sell our products to healthcare providers. For the years ended December 31, 2016 and 2015, we had worldwide sales to one manufacturer, Pfizer, of 30% and 36%, respectively, of consolidated revenue and as of December 31, 2016, accounts receivable from Pfizer was 23% of consolidated accounts receivable.

In February 2017, we completed the acquisition of Pfizer's HIS business, which we acquired in part to protect against the significant earnings exposure indicated above (see Note 2: Acquisitions and Strategic Transaction Expenses).

We report revenue on a “where-sold” basis, which reflects the revenue within the country or region in which the ultimate sale is made to our external customer.
