At December 31, 2013, our investments in money market accounts are through a money market fund that invests in high quality, short-term money market instruments which are classified as cash equivalents in the accompanying Consolidated Balance Sheet due to their short maturities. The investment seeks to provide the highest possible level of current income while still maintaining liquidity and preserving capital. From time to time, we carry cash balances in excess of federally insured limits. Our cash balance at December 31, 2013 includes approximately $146,000 held by our U.K. subsidiary. We do not hold any investments that were in a material unrealized loss position as of December 31, 2013.
