Risks and Uncertainties [Abstract] |
Concentrations of Risk | Note 13 – Concentrations of Risk Certain financial instruments potentially subject us to concentrations of credit risk. These financial instruments consist primarily of cash equivalents, trade receivables, long-term investments, notes receivable and derivative instruments. In all cases, our maximum exposure to loss from credit risk equals the gross fair value of the financial instruments. We continuously assess the need for reserves for such losses, which have been within our expectations. We do not require collateral or other security to support financial instruments subject to credit risk, except for long-term notes receivable. We limit our credit risk with respect to our cash equivalents, short-term and long-term investments and derivative i nstruments, by monitoring the credit worthiness of the financial institutions who are the counter-parties to such financial instruments. As a risk management policy, we limit the amount of credit exposure by diversifying and utilizing numerous investment grade counter-parties. With respect to our trade receivables, our credit risk is somewhat limited due to a relatively large customer base and its dispersion across different types of health care professionals and geographic areas. No single customer accounted for more than 1.2% of our net sales in 2017 or 2016. With respect to our sources of supply, our top 10 health care distribution suppliers and our single largest supplier accounted for approximately 34% and 5%, respectively, of our aggregate purchases in 2017 and approximately 34% and 6%, respectively, of our aggregate purchases in 2016. Our long-term notes receivable primarily represent strategic financing arrangements with certain industry affiliates and amounts owed to us from sales of certain businesses. Generally, these notes are secured by certain assets of the counter-party; however, in most cases our security is subordinate to other commercial financial institutions. While we have exposure to credit loss in the event of non-performance by these counter-parties, we conduct ongoing assessments of their financial and operational performance.
