(2) Comprising short-term CDs ($1.0 million) included within Level II.

(3) Does not include certain other invested assets ($14.6 million), primarily invested in limited partnerships, accounted for as cost-method investments and not measured at fair value. Also excludes investments classified as assets held for sale of $495.1 million, $839.2 million and $102.6 million, with fair values categorized in Level I, Level II and Level III, respectively.

At December 31, 2014, there were no Level III assets, and total Level III liabilities of $3.8 million accounted for 100% of total liabilities measured at fair value.

For the year ended December 31, 2014, $137.3 million of U.S. government and agency securities and $21.0 million of equity securities were transferred from Level II to Level I at the end of the period as a result of our ongoing review of the inputs to the valuations of our assets and liabilities, and the availability of unadjusted quoted prices in active markets for those identical securities as of that date. There were no investment transfers from Level I to Level II for the year ended December 31, 2014.
