[1] The values of investment securities, including mutual funds, are classified as cash and cash equivalents ($8.4 million and $10.9 million as of December 31, 2014 and 2013, respectively) and other assets ($13.1 million and $10.3 million as of December 31, 2014 and 2013, respectively). For mutual funds that are publicly traded, fair value is determined on the basis of quoted market prices and, accordingly, these investments have been classified as Level 1. Other investment securities are valued at the net asset value per share or unit multiplied by the number of shares or units held as of the measurement date and have been classified as Level 2.
