Item 7.
Management’s Discussion and Analysis of Financial Condition and Results of Operations Results of Operations – CNA Financial – (Continued) Favorable net prior year development of $123 million was recorded in 2007, including $104 million of favorable claim and allocated claim adjustment expense reserve development and $19 million of favorable premium development.
Unfavorable net prior year development of $150 million, including $208 million of unfavorable claim and allocated claim adjustment expense reserve development and $58 million of favorable premium development, was recorded in 2006.
Further information on Standard Lines Net Prior Year Development for 2007 and 2006 is included in Note 9 of the Notes to Consolidated Financial Statements included under Item 8.
Specialty Lines The following table summarizes the results of operations for Specialty Lines:
## Table 0 ##
2008 Compared with 2007 Net written premiums for Specialty Lines decreased $71 million in 2008 as compared with 2007.
Premiums written in 2008 were unfavorably impacted by competitive market conditions resulting in decreased production as compared with 2007, primarily in U. S.  Specialty Lines.
These competitive market conditions may put ongoing pressure on premium and income levels, and the expense ratio.
The unfavorable impact in premiums written was partially offset by decreased ceded premiums primarily due to decreased use of reinsurance.
Net earned premiums decreased $7 million as compared with the same period in 2007, consistent with the decrease in net written premiums.
Specialty Lines averaged rate decreases of 3.0% for 2008 and 2007 for the contracts that renewed during those periods.
Retention rates of 84.0% and 83.0% were achieved for those contracts that were up for renewal in each period.
Net income decreased $237 million in 2008 as compared with 2007.
This decrease was primarily attributable to lower net operating income and higher net realized investment losses.
See the Investments section of this MD&A for further discussion of net investment income and net realized investment results.
Net operating income decreased $117 million in 2008 as compared with 2007.
This decrease was primarily driven by significantly lower net investment income, decreased current accident year underwriting results and increased foreign currency transaction losses.
These unfavorable results were partially offset by increased favorable net prior year development.
The combined ratio increased 0.4 points in 2008 as compared with 2007.
The loss ratio improved 0.9 points, primarily due to increased favorable net prior year development in 2008 as compared to 2007.
This was partially offset by higher current accident year loss ratios recorded primarily in CNA’s errors and omissions (“E&O”) and directors and officers (“D&O”) coverages for financial institutions due to the current financial markets credit crisis.
The expense ratio increased 1.1 points in 2008 as compared with 2007.
The increase primarily related to increased underwriting expenses and reduced ceding commissions.
Item 7.
Management’s Discussion and Analysis of Financial Condition and Results of Operations Results of Operations – CNA Financial – (Continued) Approximately 81.0% and 81.2% of CNA’s total active asbestos accounts are classified as small accounts at December 31, 2008 and 2007.
CNA also evaluates its asbestos liabilities arising from its assumed reinsurance business and its participation in various pools, including Excess & Casualty Reinsurance Association (“ECRA”).
CNA carries unassigned IBNR reserves for asbestos.
These reserves relate to potential development on accounts that have not settled and potential future claims from unidentified policyholders.
The tables below depict CNA’s overall pending asbestos accounts and associated reserves:

Other policyholders with active accounts
## Table 2 ##
Some asbestos-related defendants have asserted that their insurance policies are not subject to aggregate limits on coverage.
CNA has such claims from a number of insureds.
Some of these claims involve insureds facing exhaustion of products liability aggregate limits in their policies, who have asserted that their asbestos-related claims fall within socalled “non-products” liability coverage contained within their policies rather than products liability coverage, and that the claimed “non-products” coverage is not subject to any aggregate limit.
It is difficult to predict the ultimate size of any of the claims for coverage purportedly not subject to aggregate limits or predict to what extent, if any, the attempts to assert “non-products” claims outside the products liability aggregate will succeed.
CNA’s policies also contain other
Item 1.  Business CNA Financial Corporation – (Continued) unpredictability in the law, insurance underwriting is expected to continue to be difficult in commercial lines, professional liability and other specialty coverages.
The Dodd-Frank Wall Street Reform and Consumer Protection Act expands the federal presence in insurance oversight and may increase the regulatory requirements to which CNA may be subject.
The Act’s requirements include streamlining the state-based regulation of reinsurance and nonadmitted insurance (property or casualty insurance placed from insurers that are eligible to accept insurance, but are not licensed to write insurance in a particular state).
The Act also establishes a new Federal Insurance Office within the U. S.  Department of the Treasury with powers over all lines of insurance except health insurance, certain long term care insurance and crop insurance, to, among other things, monitor aspects of the insurance industry, identify issues in the regulation of insurers that could contribute to a systemic crisis in the insurance industry or the overall financial system, coordinate federal policy on international insurance matters and preempt state insurance measures under certain circumstances.
The Act calls for numerous studies and contemplates further regulation.
The Patient Protection and Affordable Care Act and the related amendments in the Health Care and Education Reconciliation Act may increase CNA’s operating costs and underwriting losses.
This landmark legislation may lead to numerous changes in the health care industry that could create additional operating costs for CNA, particularly with respect to workers’ compensation and long term care products.
These costs might arise through the increased use of health care services by claimants or the increased complexities in health care bills that could require additional levels of review.
In addition, due to the expected number of new participants in the health care system and the potential for additional malpractice claims, CNA may experience increased underwriting risk in the lines of business that provide management and professional liability insurance to individuals and businesses engaged in the health care industry.
The lines of business that provide professional liability insurance to attorneys, accountants and other professionals who advise clients regarding the health care reform legislation may also experience increased underwriting risk due to the complexity of the legislation.
