Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Market risk is the potential loss arising from adverse changes in market rates and prices, such as interest rates, foreign exchange rates and equity prices. We are exposed to market risk through our investments, revolving credit line, term loan agreements and international operations.

Our invested assets are held primarily as cash and cash equivalents, restricted cash, available-for-sale marketable debt securities, non-marketable debt securities, certificates of deposit, U.S. treasury securities, and professionally managed short duration fixed income funds. These investments are subject to interest rate risk. The fair values of our invested assets at December 31, 2016 and December 31, 2015, approximated their respective carrying values due to their short-term duration and therefore, such market risk is not considered to be material.

We do not actively invest or trade in equity securities. In addition, we generally dispose of any significant equity securities received in conjunction with an acquisition shortly after the acquisition date.

As of December 31, 2016 we had $481.3 million of borrowings outstanding under our term loan which bears interest on a floating basis tied to the London Interbank Offered Rate (LIBOR) and therefore subject to changes in the associated interest expense. The effect of an immediate hypothetical 10% change in interest rates would not have a material effect on our Consolidated Financial Statements.

We are subject to exchange rate risk primarily in our U.K-based wholesale brokerage business that has a cost base principally denominated in British pounds and a revenue base in several other currencies, but principally in U.S. dollars. Based upon our foreign currency rate exposure as of December 31, 2016, an immediate 10% hypothetical changes of foreign currency exchange rates would not have a material effect on our Consolidated Financial Statements.
