Interest and dividend income is earned principally from the Company’s surplus cash balances and marketable securities. Unrealized losses on the contingent interest derivative on the Convertible Debentures in the three and six months ended June 30, 2012, reflect the change in value of the derivative that resulted primarily from an increase in the Company's stock price. Income from transition services agreements includes fees generated from services provided to the purchasers of divested businesses for a certain period of time to facilitate the transfer of business operations. This income decreases over time as the transition services agreements expire. Other, net for the three and six months ended June 30, 2011 includes $2.3 million of realized gains on the sale of investments. Gains on the sale of investments in the three and six months ended June 30, 2012 were not material.
