The amortized cost and approximate fair value of held-to-maturity securities are as follows:

Maturities of held-to-maturity securities at December 31, 2012 are as follows:

	Amortized Cost		Approximate Fair Value
Within One Year	$	0.6	$	0.6
One to Five Years		1.7		1.8
Five to Ten Years		0.2		0.2
After Ten Years		0.9		0.9
Total	$	3.4	$	3.5

At December 31, 2012 and December 31, 2011, the fair value of certain investments in debt and marketable securities are less than their historical cost. Total fair value of these investments was $0.8 and$1.8, respectively,for the periods then ended, which is approximately 22% and 53%, respectively, of the Company's held-to-maturity investment portfolio. These declines primarily resulted from decreases in market interest rates and failure of certain investments to maintain consistent credit quality ratings or meet projected earnings targets.

Based on evaluation of available evidence, including changes in market interest rates, credit rating information and information obtained from regulatory filings, management believes the declines in fair value for these securities are temporary.

Should the impairment of any of these securities become other-than-temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period in whichthe permanent impairment is identified.
