Company Outlook	Rating	Description
Strong	Aaa	Exceptional financial security. While the financial strength of these companies is likely to change, such changes as can be visualized are most unlikely to impair their fundamentally strong position.
	Aa	Excellent financial security, together with the Aaa group, they constitute what are generally known as high-grade companies. They are rated lower than Aaa companies because long-term risks appear somewhat larger.
	A	Good financial security. However, elements may be present which suggest a susceptibility to impairment sometime in their future.
	Baa	Adequate financial security. However, certain protective elements may be lacking or may be characteristically unreliable over any great length of time.
Weak	Ba	Questionable financial security. Often the ability of these companies to meet policyholder obligations may be very moderate and thereby not well safeguarded in the future.
	B	Poor financial security. Assurance of punctual payment of policyholder obligations over any long period of time is small.
	Caa	Very poor financial security. They may be in default on their policyholder obligations or there may be present elements of danger with respect to punctual payment of policyholder obligations claims.
	Ca	Extremely poor financial security. Such companies are often in default on their policyholder obligations or have other marked shortcomings.
	C	The lowest rated class of insurance company; can be regarded as having extremely poor prospects of ever offering financial security.
1, 2, 3 Modifiers		These modifiers can be used for each generic rating category from Aa to B. 1 indicates that the insurance company ranks in the higher end of its generic rating category. 2 indicates a mid-range ranking. 3 indicates that the company ranks in the lower end of its generic category.

Standard & Poor's

This rating service rates the claims-paying ability of over 300 insurance organizations worldwide, and monitors public data on another 2,000 U.S. companies.

Company Outlook	Rating	Description
Strong	AAA	Superior financial security on an absolute and relative basis. Capacity to meet policyholder obligations is overwhelming under a variety of economic and underwriting conditions.
	AA	Excellent financial security. Capacity to meet policyholder obligations is strong under a variety of economic and underwriting conditions.
	A	Good financial security, but capacity to meet policyholder obligations is somewhat susceptible to adverse economic and underwriting conditions.
	BBB	Adequate financial security, but capacity to meet policyholder obligations is susceptible to adverse economic and underwriting conditions.
Weak	BB	Financial security may be adequate, but capacity to meet policyholder obligations, particularly with respect to long-term or "long-tail" policies, is vulnerable to adverse economic and underwriting conditions.
	B	Vulnerable financial security. Currently able to meet policyholder obligations, but capacity to meet policyholder obligations is particularly vulnerable to adverse economic and underwriting conditions.
	CCC	Extremely vulnerable financial security. Continued capacity to meet policyholder obligations is highly questionable unless favorable economic and underwriting conditions prevail.
	NR	Not Rated. The insurer is not rated by Standard & Poor's.
	R	Regulatory action. As of the date indicated, the insurer is under supervision of insurance regulators following rehabilitation, receivership, liquidation, or any other action that reflects regulatory concern about the insurer's financial condition. Information on this status is provided by the National Association of Insurance Commissioners and other regulatory bodies. Although believed to be accurate, this information is not guaranteed. The "R" rating does not apply to insurers subject only to non financial actions such as market conduct violations.
Plus (+) or Minus (-) Sign		The ratings from "AA" to "B" may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories. Standard & Poor's ratings and other assessments of credit worthiness and financial strength are not a recommendation to purchase or discontinue any policy or contract issues by an insurer or to buy, hold or sell any security issued by an insurer. In addition, neither a rating nor an assessment is a guaranty of an insurer's financial strength.
