Note 2.	Significant Accounting Policies
	All highly liquid investments with maturity of three months or less when purchased are considered to be cash equivalents. The carrying value of cash equivalents approximates its fair value based on its nature.
	At September 30, 2013, December 31, 2012 and September 30, 2012 all cash and cash equivalents were invested in a United States Treasury money market fund, of which an affiliate of the Company serves as the investment manager of the money market fund.
	The Company may from time to time invest in marketable securities that are bought and held principally for the purpose of selling them in the near term and are classified as trading securities. Trading securities are recorded at fair value on the balance sheet in current assets, with the change in fair value during the period included in earnings.
	Basic earnings per share is based on the weighted-average number of common shares outstanding during each period. Diluted earnings per share is based on basic shares plus the incremental shares that would be issued upon the assumed exercise of in-the-money stock options and unvested restricted stock using the treasury stock method and, if dilutive.
	Certain line items in the previously reported financial statements have been reclassified to conform to the current presentation.
