CNA Financial Corporation
Notes to Condensed Consolidated Financial Statements (Unaudited)
Note A. General
Basis of Presentation
The Condensed Consolidated Financial Statements include the accounts of CNA Financial Corporation (CNAF) and its subsidiaries. Collectively, CNAF and its subsidiaries are referred to as CNA or the Company. Loews Corporation (Loews) owned approximately 90% of the outstanding common stock of CNAF as of March 31,June 30, 2016.
The accompanying Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Intercompany amounts have been eliminated. Certain financial information that is normally included in annual financial statements, including certain financial statement notes, prepared in accordance with GAAP, is not required for interim reporting purposes and has been condensed or omitted. These statements should be read in conjunction with the Consolidated Financial Statements and notes thereto included in CNAF's Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2015, including the summary of significant accounting policies in Note A. The preparation of Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.
The interim financial data as of March 31,June 30, 2016 and for the three and six months ended March 31,June 30, 2016 and 2015 is unaudited. However, in the opinion of management, the interim data includes all adjustments, including normal recurring adjustments, necessary for a fair statement of the Company's results for the interim periods. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year.
Recently Adopted Accounting Standards Updates (ASU)
In April 2015, the Financial Accounting Standards Board (FASB) issued ASU No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The updated accounting guidance requires debt issuance costs to be presented as a deduction from the corresponding debt liability instead of the historical presentation as an unamortized debt issuance asset. As of January 1, 2016, the Company adopted the updated accounting guidance retrospectively. The Company adjusted its previously reported financial information included herein to reflect the change in accounting guidance for debt issuance costs. The impacts of adopting the new accounting standard on the Company’s Consolidated Balance Sheet as of December 31, 2015, were a decrease in Other assets and a decrease in Long term debt of $2 million.
In May 2015, the FASB issued ASU No. 2015-07, Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent). The updated accounting guidance removes the requirement to categorize assets measured at fair value utilizing the net asset value per share (or equivalent) practical expedient within the fair value hierarchy. As of January 1, 2016, the Company adopted the updated accounting guidance retrospectively. The Company adjusted its previously reported financial information included herein to reflect the change in accounting guidance for assets measured using the net asset value. The impactsimpact of adopting the new accounting standard resulted in excluding overseas deposits of $28 million and $27 million from the fair value level disclosure as of March 31,June 30, 2016 and December 31, 2015.

Recently Issued ASUsAccounting Standards Pending Adoption
In May 2015, the FASB issued ASU No. 2015-09, Financial Services-Insurance (Topic 944): Disclosures about
Short-Duration Contracts.The updated accounting guidance requires enhanced disclosures to provide additional information about insurance liabilities for short-duration contracts. The guidance is effective for annual periods beginning after December 15, 2015, and interim periods within the annual periods beginning after December 15, 2016. The Company is currently evaluating the effect the updated guidance will have on the Company's financial statement disclosures.disclosures but expects to provide additional incurred and paid claims development information by accident year, quantitative information about claim frequency and the history of claims duration for significant lines of business within the Company’s annual financial statements.
In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The updated accounting guidance requires changes to the reporting model for financial instruments. The guidance is effective for interim and annual periods beginning after December 15, 2017. The Company is currently evaluating the effect the guidance will have on the Company's financial statements, and expects the primary change for the Company to be the requirement for equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income.
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842): Accounting for Leases. The updated accounting guidance requires lessees to recognize on the balance sheet the assets and liabilities for the rights and obligations created by all leases, including those historically accounted for as operating leases. The guidance is effective for interim and annual periods beginning after December 15, 2018. The Company is currently evaluating the effect the updated guidance will have on the Company's financial statements.
In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The updated accounting guidance simplifies the accounting for share-based payment award transactions including income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The guidance is effective for annual periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018. The Company is currently evaluating the effect the updated guidance will have on the Company’s financial statements.
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The updated accounting guidance requires changes to the recognition of credit losses on financial instruments not accounted for at fair value through net income. The guidance is effective for interim and annual periods beginning after December 15, 2019. The Company is currently evaluating the effect the guidance will have on the Company's financial statements, but expects the primary changes to be the use of the expected credit loss model for its mortgage loan portfolio and reinsurance receivables and the presentation of credit losses within the available-for-sale fixed maturities portfolio through an allowance method rather than as a direct write-down. The expected credit loss model will require a financial asset to be presented at the net amount expected to be collected. The allowance method for available-for-sale debt securities will allow the Company to record reversals of credit losses when the estimate of credit losses declines.


Note B. Earnings Per Share
Earnings per share is based on the weighted average number of outstanding common shares. Basic earnings (loss) per share excludes the effect of dilutive securities and is computed by dividing Net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.
For the three and six months ended March 31,June 30, 2016, and 2015, approximately 542409 thousand and 654473 thousand potential shares attributable to exercises under stock-based employee compensation plans were included in the calculation of diluted earnings per share. For those same periods, approximately 178 thousand and 180 thousand potential shares attributable to exercises under stock-based employee compensation plans were not included in the calculation of diluted earnings per share because the effect would have been antidilutive.
For the three and 182six months ended June 30, 2015, approximately 423 thousand and 543 thousand potential shares attributable to exercises under stock-based employee compensation plans were included in the calculation of diluted earnings per share. For those same periods, approximately 238 thousand and 208 thousand potential shares attributable to exercises under stock-based employee compensation plans were not included in the calculation of diluted earnings per share because the effect would have been antidilutive.

The net unrealized gains on investments included in the tables above are recorded as a component of Accumulated other comprehensive income (AOCI). When presented in AOCI, these amounts are net of tax and any required Shadow Adjustments. To the extent that unrealized gains on fixed income securities supporting certain products within the Life & Group Non-Core segment would result in a premium deficiency if realized, a related increase in Insurance reserves is recorded, net of tax, as a reduction of net unrealized gains through Other comprehensive income (loss) (Shadow Adjustments). As of March 31,June 30, 2016 and December 31, 2015, the net unrealized gains on investments included in AOCI were net of after-taxcorrespondingly reduced by Shadow Adjustments of $1,311$1,682 million and $1,111 million.

The following tables present the estimated fair value and gross unrealized losses of fixed maturity and equity securities in a gross unrealized loss position by the length of time in which the securities have continuously been in that position.

Based on current facts and circumstances, the Company believes the unrealized losses presented in the March 31,June 30, 2016 table above, are not indicative of the ultimate collectibility of the current amortized cost of the securities, but rather are attributable to changes in interest rates, credit spreads and other factors, including volatility in the energy and metals and mining sectors. As of March 31, 2016, the Company held fixed maturity securities and equity securities with an estimated fair value of $2,446 million and a cost or amortized cost of $2,464 million in the energy and metals and mining sectors. The portion of these securities in a gross unrealized loss position had an estimated fair value of $1,069 million and a cost or amortized cost of $1,202 million.factors. The Company has no current intent to sell securities with unrealized losses, nor is it more likely than not that it will be required to sell prior to recovery of amortized cost; accordingly, the Company has determined that there are no additional OTTI losses to be recorded as of March 31,June 30, 2016.
The following table presents the activity related to the pretax credit loss component reflected in Retained earnings on fixed maturity securities still held as of March 31,June 30, 2016 and 2015 for which a portion of an OTTI loss was recognized in Other comprehensive income (loss).

Note D. Fair Value
Fair value is the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following fair value hierarchy is used in selecting inputs, with the highest priority given to Level 1, as these are the most transparent or reliable.
Level 1 - Quoted prices for identical instruments in active markets.
Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets.
Level 3 - Valuations derived from valuation techniques in which one or more significant inputs are not observable.
Prices may fall within Level 1, 2 or 3 depending upon the methodology and inputs used to estimate fair value for each specific security. In general the Company seeks to price securities using third-party pricing services. Securities not priced by pricing services are submitted to independent brokers for valuation and, if those are not available, internally developed pricing models are used to value assets using a methodology and inputs the Company believes market participants would use to value the assets. Prices obtained from third-party pricing services or brokers are not adjusted by the Company.
The Company performs control procedures over information obtained from pricing services and brokers to ensure prices received represent a reasonable estimate of fair value and to confirm representations regarding whether inputs are observable or unobservable. Procedures include i) the review of pricing service or broker pricing methodologies, ii) back-testing, where past fair value estimates are compared to actual transactions executed in the market on similar dates, iii) exception reporting, where period-over-period changes in price are reviewed and challenged with the pricing service or broker based on exception criteria, iv) deep dives, where the Company performs an independent analysis of the inputs and assumptions used to price individual securities and v) pricing validation, where prices received are compared to prices independently estimated by the Company.

Securities shown on the previous pages may be transferred in or out of levels within the fair value hierarchy based on the availability of observable market information and quoted prices used to determine the fair value of the security. The availability of observable market information and quoted prices varies based on market conditions and trading volume. During the three and six months ended March 31,June 30, 2016 and 2015 there were no transfers between Level 1 and Level 2. The Company's policy is to recognize transfers between levels at the beginning of quarterly reporting periods.
Valuation Methodologies and Inputs
The following section describes the valuation methodologies and relevant inputs used to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which the instruments are generally classified.
Fixed Maturity Securities
Level 1 securities include highly liquid and exchange traded bonds and redeemable preferred stock, valued using quoted market prices. Level 2 securities include most other fixed maturity securities as the significant inputs are observable in the marketplace. All classes of Level 2 fixed maturity securities are valued using a methodology based on information generated by market transactions involving identical or comparable assets, a discounted cash flow methodology, or a combination of both when necessary. Common inputs for all classes of fixed maturity securities include prices from recently executed transactions of similar securities, marketplace quotes, benchmark yields, spreads off benchmark yields, interest rates and U.S. Treasury or swap curves. Specifically for asset-backed securities, key inputs include prepayment and default projections based on past performance of the underlying collateral and current market data. Fixed maturity securities are primarily assigned to Level 3 in cases where broker/dealer quotes are significant inputs to the valuation and there is a lack of transparency as to whether these quotes are based on information that is observable in the marketplace. Level 3 securities also include private placement debt securities whose fair value is determined using internal models with inputs that are not market observable.
Equity Securities
Level 1 equity securities include publicly traded securities valued using quoted market prices. Level 2 securities are primarily non-redeemable preferred stocks and common stocks valued using pricing for similar securities, recently executed transactions and other pricing models utilizing market observable inputs. Level 3 securities are primarily priced using broker/dealer quotes and internal models with inputs that are not market observable.

Derivative Financial InvestmentsOther invested assets - Federal Home Loan Bank of Chicago (FHLBC) Stock
Level 2 securities primarily include the embedded derivative on funds withheld liability. The embedded derivative on funds withheld liability is valued using the change in fair value of FHLBC stock is equal to par because it can only be redeemed by the assets supportingFHLBC at par or sold to another member of the funds withheld liability, which are fixed maturity securities valued with observable inputs.FHLBC at par and is classified as Level 2.
Short Term Investments
Securities that are actively traded or have quoted prices are classified as Level 1. These securities include money market funds and treasury bills. Level 2 primarily includes commercial paper, for which all inputs are market observable. Fixed maturity securities purchased within one year of maturity are classifiedvalued consistent with fixed maturity securities discussed above. Short term investments as presented in the tables above differ from the amounts presented on the Condensed Consolidated Balance Sheets because certain short term investments, such as time deposits, are not measured at fair value.
Life Settlement Contracts
The fair values of life settlement contracts are determined as the present value of the anticipated death benefits less anticipated premium payments based on contract terms that are distinct for each insured, as well as the Company's own assumptions for mortality, premium expense and the rate of return that a buyer would require on the contracts, as no comparable market pricing data is available.
Other invested assets - Federal Home Loan Bank of Chicago (FHLBC) StockDerivative Financial Investments
Level 2 securities primarily include the embedded derivative on funds withheld liability. The embedded derivative on funds withheld liability is valued using the change in fair value of FHLBC stock is equal to par because it can only be redeemed by the FHLBC at par or sold to another member ofassets supporting the FHLBC at par and is classified as Level 2.funds withheld liability, which are fixed maturity securities valued with observable inputs.
Other invested assets - Overseas Deposits
As of March 31,June 30, 2016 and December 31, 2015, there were approximately $28 million and $27 million respectively of overseas deposits, which can be redeemed at net asset value in 90 days or less. Overseas deposits are excluded from the fair value hierarchy because their fair value is recorded using the net asset value per share (or equivalent) practical expedient.
Significant Unobservable Inputs
The following tables present quantitative information about the significant unobservable inputs utilized by the Company in the fair value measurementsmeasurement of Level 3 assets. Valuations for assets and liabilities not presented in the tables below are primarily based on broker/dealer quotes for which there is a lack of transparency as to inputs used to develop the valuations. The quantitative detail of these unobservable inputs is neither provided nor reasonably available to the Company.

For fixed maturity securities, an increase to the credit spread assumptions would result in a lower fair value measurement. For life settlement contracts, an increase in the discount rate risk premium or decrease in the mortality assumption would result in a lower fair value measurement.

The following methods and assumptions were used to estimate the fair value of these financial assets and liabilities.
The fair value of Mortgage loans was based on the present value of the expected future cash flows discounted at the current interest rate for origination of similar quality loans, adjusted for specific loan risk.
The Company's senior notes and debentures were valued based on observable market prices. The fair value for other debt was estimated using discounted cash flows based on current incremental borrowing rates for similar borrowing arrangements.
The carrying amounts reported on the Condensed Consolidated Balance Sheets for Cash, Short term investments not carried at fair value, Accrued investment income and certain Other assets and Other liabilities approximate fair value due to the short term nature of these items. These assets and liabilities are not listed in the tables above.


Note E. Claim and Claim Adjustment Expense Reserves
The Company's property and casualty insurance claim and claim adjustment expense reserves represent the estimated amounts necessary to resolve all outstanding claims, including incurred but not reported (IBNR) claims as of the reporting date. The Company's reserve projections are based primarily on detailed analysis of the facts in each case, the Company's experience with similar cases and various historical development patterns. Consideration is given to such historical patterns as field reserving trends and claims settlement practices, loss payments, pending levels of unpaid claims and product mix, as well as court decisions, economic conditions including inflation and public attitudes. All of these factors can affect the estimation of claim and claim adjustment expense reserves.
Establishing claim and claim adjustment expense reserves, including claim and claim adjustment expense reserves for catastrophic events that have occurred, is an estimation process. Many factors can ultimately affect the final settlement of a claim and, therefore, the necessary reserve. Changes in the law, results of litigation, medical costs, the cost of repair materials and labor rates can all affect ultimate claim costs. In addition, time can be a critical part of reserving determinations since the longer the span between the incidence of a loss and the payment or settlement of the claim, the more variable the ultimate settlement amount can be. Accordingly, short-tail claims, such as property damage claims, tend to be more reasonably estimable than long-tail claims, such as workers' compensation, general liability and professional liability claims. Adjustments to prior year reserve estimates, if necessary, are reflected in the results of operations in the period that the need for such adjustments is determined. There can be no assurance that the Company's ultimate cost for insurance losses will not exceed current estimates.
Catastrophes are an inherent risk of the property and casualty insurance business and have contributed to material period-to-period fluctuations in the Company's results of operations and/or equity. The Company reported catastrophe losses, net of reinsurance, of $36$85 million and $29$121 million for the three and six months ended March 31, 2016 and 2015.June 30, 2016. Catastrophe losses in 2016 relatedresulted primarily tofrom U.S. weather-related events.events and the Fort McMurray wildfires. The Company reported catastrophe losses, net of reinsurance, of $60 million and $89 million for the three and six months ended June 30, 2015.

Three Months
2016
Favorable development in medical professional liability was due to lower than expected severity for individual healthcare professionals and allied facilities for accident years 2014 and prior.
Favorable development in other professional liability and management liability was primarily related to lower than expected frequency of claims in accident years 2010 through 2015, mainly driven by professional services. This was partially offset by unfavorable development in accident year 2015 related to an increase in management liability frequency of larger claims.
2015
Overall, favorable development in medical professional liability was primarily due to lower than expected severity for individual healthcare professionals and allied facilities in accident years 2009 through 2012. Unfavorable development was recorded related to increased claim frequency in the aging services business in accident years 2009 and 2010.
Favorable development of $38 million was recorded in other professional liability and management liability related to lower than expected severity for professional services primarily in accident years 2010 and prior. Unfavorable development of $37 million was recorded primarily related to increased claim frequency on public company management liability in accident years 2012 through 2014.
Favorable development for other coverages was primarily due to better than expected claim frequency in property coverages provided to Specialty customers in accident year 2014.

Favorable development of $41 million was recorded in other professional liability and management liability primarily related to lower than expected severity in accident years 2010 and prior for professional services. Unfavorable development of $37 million was recorded primarily related to increased claim frequency on public company management liability in accident years 2012 through 2014.
Favorable development for other coveragecoverages was primarily due to better than expected claim frequency in property coverages provided to Specialty customers in accident year 2014.

Favorable development for commercial auto was primarily due to favorable settlements on claims in accident years 20112010 through 2014.
Favorable development for general liability was primarily due to better than expected claim settlements in accident years 2012 through 2014 and better than expected severity on umbrella claims in accident years 2010 through 2013.
Unfavorable development for workers’ compensation was due to a reduction in estimated recoveries on war hazard claims for Defense Base Act contractors, which was partially offset by favorable development related to lower than expected frequencies for our small and middle market businesses in accident years 2009 through 2014.
Favorable development for property and other was primarily due to better than expected loss emergence in accident years 2013 through 2015.
2015
In the aggregate, the unfavorable loss development of $16 million was driven by an extra contractual obligation loss and losses associated with premium development. The reserve development discussed below was largely offsetting.
Unfavorable development for workers’ compensation was primarily due to higher than expected severity related to Defense Base Act contractors in accident years 2008 through 2013.
Favorable development for property and other was primarily due to better than expected loss emergence from 2012 catastrophe events and better than expected claim frequency of large claims in accident year 2014.

Asbestos and Environmental Pollution Reserves (A&EP)
In 2010, Continental Casualty Company (CCC) together with several of the Company’s insurance subsidiaries completed a transaction with National Indemnity Company (NICO), a subsidiary of Berkshire Hathaway Inc., under which substantially all of the Company’s legacy A&EP liabilities were ceded to the NICO through a Loss Portfolio Transfer (Loss Portfolio Transfer or LPT)(LPT). At the effective date of the transaction, the Company ceded approximately $1.6 billion of net A&EP claim and allocated claim adjustment expense reserves to NICO under a retroactive reinsurance agreement with an aggregate limit of $4 billion. The $1.6 billion of claim and allocated claim adjustment expense reserves ceded to NICO was net of $1.2 billion of ceded claim and allocated claim adjustment expense reserves under existing third-party reinsurance contracts. The NICO LPT aggregate reinsurance limit also covers credit risk on the existing third-party reinsurance related to these liabilities. The Company paid NICO a reinsurance premium of $2 billion and transferred to NICO billed third-party reinsurance receivables related to A&EP claims with a net book value of $215 million, resulting in total consideration of $2.2 billion.
Through December 31, 2013, the Company recognized $0.9 billion of additional amounts ceded under the LPT. As a result, the cumulative amounts ceded under the LPT exceeded the $2.2 billion consideration paid, resulting in the NICO LPT moving into a gain position, requiring deferred retroactive reinsurance accounting treatment. This deferred gain is recognized in earnings in proportion to actual paid recoveries under the LPT. Over the life of the contract, there is no economic impact as long as any additional losses incurred are within the limit of the LPT. In a period in which a change in the estimate of ceded incurred losses is recognized, the change to the deferred gain is cumulatively recognized in earnings as if the revised estimate was available at the effective date of the LPT.
The following table presents the impact of the Loss Portfolio Transfer on the Condensed Consolidated Statements of Operations.

The Company expected to completecompleted its reserve review of A&EP reserves in the second quarter of 2016; however, during the first quarter of 2016 the Company received communication from NICO that their reserve review indicated a substantial increase in reserves. As a result, the Company accelerated and completed its reserve review during the first quarter.2016. Based upon the Company's accelerated review, net unfavorable development prior to cessions to the LPT of $200 million was recognized; $146 million related to asbestos claims and $54 million related to environmental pollution claims.recognized. The unfavorable development was driven by an increase in anticipated future expenses associated with determination of coverage, higher anticipated payouts associated with a limited number of historical accounts having significant asbestos exposures and higher than expected severity on pollution claims. This unfavorable development was ceded to NICO under the LPT; however, the Company’s reported earnings were negatively affected due to the application of retroactive reinsurance accounting, as only a portion of the additional amounts ceded under the LPT were recognized in the currentthat quarter. Retroactive reinsurance accounting resulted in the recognition of a reinsurance benefit of $73 million in the current quarter, while the remaining $127 million of incurred losses covered by the LPT will be recognized as a benefit through future earnings in proportion to the actual paid recoveries subject to the NICO LPT. All amounts recognized related to the LPT are recorded within Insurance claims and policyholders’ benefits in the Condensed Consolidated Statement of Operations.
As of March 31,June 30, 2016 and December 31, 2015, the cumulative amounts ceded under the LPT were $2.8 billion and $2.6 billion. Cumulative losses recognized in the Company's Condensed Consolidated Statement of Operations that are covered by the LPT were $368The unrecognized deferred retroactive reinsurance benefit was $359 million and $241 million as of March 31,June 30, 2016 and December 31, 2015.
NICO established a collateral trust account as security for its obligations to the Company. The fair value of the collateral trust account was $2.7$2.6 billion and $2.8 billion as of March 31,June 30, 2016 and December 31, 2015. In addition, Berkshire Hathaway Inc. guaranteed the payment obligations of NICO up to the full aggregate reinsurance limit

as well as certain of NICO’s performance obligations under the trust agreement. NICO is responsible for claims handling and billing and collection from third-party reinsurers related to the Company’s A&EP claims.

In the second quarter of 2015, the Company eliminated future benefit accruals associated with the CNA Retirement Plan (Plan) effective June 30, 2015.  Employees who were continuing to accrue under this Plan up until that date are entitled to an accrued benefit payable based on their eligible compensation and accrued service through June 30, 2015, in accordance with the terms of the Plan. Starting with the first pay period after July 1, 2015, affected employees began receiving enhanced employer contributions in the CNA 401(k) Plus Plan similar to employees who elected to cease accruals effective December 31, 1999. Employees who elected to cease accruals effective December 31, 1999 are not affected by this curtailment. This curtailment resulted in a $55 million decrease in the Plan benefit obligation liability and a reduction of the unrecognized actuarial losses included in AOCI. In connection with the curtailment, the Company remeasured the plan benefit obligation which resulted in an increase in the discount rate used to determine the benefit obligation from 3.85% to 4.00%.


Note H. Commitments, Contingencies and Guarantees
Commitments and Contingencies
The Company holds an investment in a real estate joint venture in which the Company, on a joint and several basis with the other unrelated shareholders guaranteed to fund operating deficits of the joint venture and an operating lease for an office building entered into by the venture. The lease was terminated in March 2016. In the event that the other parties to the joint venture are unable to meet their commitments in funding this joint venture, the Company would be required to assume future obligations, primarily related to the wind-down of the lease and joint venture. The Company does not believe it is likely that it will be required to do so. However, as of March 31,June 30, 2016, the maximum potential loss that the Company could be required to pay under this guarantee, in excess of amounts already recorded, was approximately $18$16 million. If the Company were required to assume future obligations, the Company would have the right to pursue reimbursement from the other shareholders.
Guarantees
As of March 31,June 30, 2016 and December 31, 2015, the Company had recorded liabilities of approximately $5 million related to guarantee and indemnification agreements and management believes that it is not likely that any future indemnity claims will be significantly greater than the amounts recorded.
In the course of selling business entities and assets to third parties, the Company agreed to guarantee the performance of certain obligations of a previously owned subsidiary and to indemnify purchasers for losses arising out of breaches of representation and warranties with respect to the business entities or assets sold, including, in certain cases, losses arising from undisclosed liabilities or certain named litigation. Such guarantee and indemnification agreements in effect for sales of business entities, assets and third-party loans may include provisions that survive indefinitely. As of March 31,June 30, 2016, the aggregate amount related to quantifiable guarantees was $375 million and the aggregate amount related to indemnification agreements was $259 million. Should the Company be required to make payments under the guarantee, it would have the right to seek reimbursement in certain cases from an affiliate of a previously owned subsidiary.
In addition, the Company has agreed to provide indemnification to third-party purchasers for certain losses associated with sold business entities or assets that are not limited by a contractual monetary amount. As of March 31,June 30, 2016, the Company had outstanding unlimited indemnifications in connection with the sales of certain of its business entities or assets that included tax liabilities arising prior to a purchaser's ownership of an entity or asset, defects in title at the time of sale, employee claims arising prior to closing and in some cases losses arising from certain litigation and undisclosed liabilities. Certain provisions of the indemnification agreements survive indefinitely, while others survive until the applicable statutes of limitation expire, or until the agreed-upon contract terms expire.
The Company also provided guarantees, if the primary obligor fails to perform, to holders of structured settlement annuities provided by a previously owned subsidiary. As of March 31,June 30, 2016, the potential amount of future payments the Company could be required to pay under these guarantees was approximately $2.0 billion, which will be paid over the lifetime of the annuitants. The Company does not believe any payment is likely under these guarantees, as the Company is the beneficiary of a trust that must be maintained at a level that approximates the discounted reserves for these annuities.

Note J. Business Segments
The Company's core property and casualty commercial insurance operations are aggregated and reported in three business segments: Specialty, Commercial and International. The Company's non-core operations are managed and reported in two segments: Life & Group Non-Core and Corporate & Other Non-Core.
The accounting policies of the segments are the same as those described in Note A to the Consolidated Financial Statements within CNAF's Annual Report on Form 10-K for the year ended December 31, 2015. The Company manages most of its assets on a legal entity basis, while segment operations are generally conducted across legal entities. As such, only Insurance and Reinsurance receivables, Insurance reserves, Deferred acquisition costs and Goodwill are readily identifiable for all individual segments. Distinct investment portfolios are not maintained for every individual segment; accordingly, allocation of assets to each segment is not performed. Therefore, a significant portion of Net investment income and Realized investment gains or losses are allocated primarily based on each segment's net carried insurance reserves, as adjusted. All significant intersegment income and expense has been eliminated. Income taxes have been allocated on the basis of the taxable income of the segments.
In the following tables, certain financial measures are presented to provide information used by management to monitor the Company's operating performance. Management utilizes these financial measures to monitor the Company's insurance operations and investment portfolio. Net operating income (loss), which is derived from certain income statement amounts, is used by management to monitor performance of the Company's insurance operations. The Company's investment portfolio is monitored by management through analysis of various factors including unrealized gains and losses on securities, portfolio duration and exposure to market and credit risk. Based on such analyses, the Company may recognize an OTTI loss on an investment security in accordance with its policy, or sell a security, which may produce realized gains and losses.
Net operating income (loss) is calculated by excluding from net income (loss) the after-tax effects of 1)i) net realized investment gains (losses) 2)ii) income or loss from discontinued operations and 3)iii) any cumulative effects of changes in accounting guidance. The calculation of net operating income excludes net realized investment gains (losses) because net realized investment gains (losses) are largely discretionary, except for some losses related to OTTI, and are generally driven by economic factors that are not necessarily consistent with key drivers of underwriting performance, and are therefore not considered an indication of trends in insurance operations.









The Company's results of operations and selected balance sheet items by segment are presented in the following tables.

Item 2. Management's Discussion and Analysis (MD&A) of Financial Condition and Results of Operations
Overview
The following discussion highlights significant factors affecting the Company. References to “we,” “our,” “us” or like terms refer to the business of CNA. Based on 2014 statutory net written premiums, we are the eighth largest commercial insurance writer and the 14th largest property and casualty insurance organization in the United States of America.
The following discussion should be read in conjunction with the Condensed Consolidated Financial Statements included under Part I, Item 1 of this Form 10-Q and Item 1A Risk Factors and Item 7 Management's Discussion and Analysis of Financial Condition and Results of Operations, which are included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2015.
We utilize the net operating income (loss) financial measure to monitor our operations. Net operating income (loss) is calculated by excluding from net income (loss) the after-tax effects of 1) net realized investment gains or losses, 2) income or loss from discontinued operations and 3) any cumulative effects of changes in accounting guidance. See further discussion regarding how we manage our business in Note J to the Condensed Consolidated Financial Statements included under Part I, Item 1.
In the evaluation of the results of our core Specialty, Commercial and International segments, we utilize the loss ratio, the expense ratio, the dividend ratio and the combined ratio. These ratios are calculated using GAAP financial results. The loss ratio is the percentage of net incurred claim and claim adjustment expenses to net earned premiums. The expense ratio is the percentage of insurance underwriting and acquisition expenses, including the amortization of deferred acquisition costs, to net earned premiums. The dividend ratio is the ratio of policyholders' dividends incurred to net earned premiums. The combined ratio is the sum of the loss, expense and dividend ratios. In addition we also utilize rate, retention and new business in evaluating operating trends. Rate represents the average change in price on policies that renew excluding exposure change. Retention represents the percentage of premium dollars renewed in comparison to the expiring premium dollars from policies available to renew. New business represents premiums from policies written with new customers and additional policies written with existing customers.
Changes in estimates of claim and allocated claim adjustment expense reserves and premium accruals, net of reinsurance, for prior years are defined as net prior year development within this MD&A. These changes can be favorable or unfavorable. Net prior year development does not include the effect of related acquisition expenses. Further information on our reserves is provided in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1.


CONSOLIDATED OPERATIONS
The following table includes the consolidated results of our operations. For more detailed components of our business operations and the net operating income financial measure, see the segment discussions within this MD&A. For further discussion of Net investment income and Net realized investment results, see the Investments section of this MD&A.

Net income$66
 $233
Net operating income decreased $134 million for the three months ended March 31, 2016 as compared with the same period 2015. Results in 2016 within our Corporate and Other Non-Core segment were negatively affected by an $83 million after-tax charge related to the application of retroactive reinsurance accounting to adverse reserve development ceded under the 2010 A&EP Loss Portfolio Transfer, as further discussed in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1. Net operating income decreased $57 million for our core segments due to a decrease in net investment income driven by lower limited partnership returns, partially offset by improved underwriting results. Excluding the effect of the retroactive reinsurance charge, net operating results for our non-core segments improved $6 million primarily driven by our long term care business. Catastrophe losses were $24 million after tax for the three months ended March 31, 2016 as compared to $19 million after tax for the same period 2015.
Favorable net prior year development of $66 million was recorded for the three months ended March 31, 2016 as compared with unfavorable net prior year development of $2 million for the three months ended March 31, 2015 related to our Specialty, Commercial, International and Corporate & Other Non-Core segments. Further information on net prior year development is in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1.


CRITICAL ACCOUNTING ESTIMATES
The preparation of the Condensed Consolidated Financial Statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the amounts of revenues and expenses reported during the period. Actual results may differ from those estimates.
Our Condensed Consolidated Financial Statements and accompanying notes have been prepared in accordance with GAAP applied on a consistent basis. We continually evaluate the accounting policies and estimates used to prepare the Condensed Consolidated Financial Statements. In general, our estimates are based on historical experience, evaluation of current trends, information from third-party professionals and various other assumptions that are believed to be reasonable under the known facts and circumstances.
The accounting estimates below are considered by us to be critical to an understanding of our Condensed Consolidated Financial Statements as their application places the most significant demands on our judgment.
Insurance Reserves
Reinsurance and Insurance Receivables
Valuation of Investments and Impairment of Securities
Long Term Care Policies
Pension and Postretirement Benefit Obligations
Income Taxes
Due to the inherent uncertainties involved with these types of judgments, actual results could differ significantly from estimates and may have a material adverse impact on our results of operations or equity. See the Critical Accounting Estimates section of our Management's Discussion and Analysis of Financial Condition and Results of Operations included under Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2015 for further information.

Three Month Comparison
Net operating income increased $69 million for the three months ended June 30, 2016 as compared with the same period in 2015. Results in 2015 within our Corporate and Other Non-Core segment were negatively affected by a $54 million after-tax charge related to the application of retroactive reinsurance accounting to adverse reserve development ceded under the 2010 A&EP Loss Portfolio Transfer, as further discussed in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1. Excluding the effect of the retroactive reinsurance charge, net operating results for our non-core segments improved $23 million primarily driven by our long term care business. Net operating income decreased $8 million for our core segments due to improved underwriting results, largely due to favorable net prior year development, which were more than offset by foreign currency exchange rate losses and lower investment income.
Favorable net prior year development of $106 million and $20 million was recorded for the three months ended June 30, 2016 and 2015 related to our Specialty, Commercial and International segments. Further information on net prior year development is in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1. Catastrophe losses were $58 million after tax for the three months ended June 30, 2016 as compared to $39 million after tax for the same period in 2015.


Six Month Comparison
Net operating income decreased $65 million for the six months ended June 30, 2016 as compared with the same period in 2015. Net operating income decreased $65 million for our core segments due to a decrease in net investment income, driven by lower limited partnership returns, and higher non-catastrophe current accident year losses, partially offset by higher net favorable prior year development. Results for our non-core segments were negatively affected in both periods by after tax charges related to the application of retroactive reinsurance accounting to adverse reserve development ceded under the 2010 A&EP Loss Portfolio Transfer. The Loss Portfolio Transfer drove $25 million of the period over period change, as further discussed in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1. Excluding the effect of the retroactive reinsurance charges, net operating results for our non-core segments improved $29 million primarily driven by our long term care business.
Favorable net prior year development of $172 million and $18 million was recorded for the six months ended June 30, 2016 and 2015 related to our Specialty, Commercial and International segments. Further information on net prior year development is in Note E to the Condensed Consolidated Financial Statements included under Part I, Item 1. Catastrophe losses were $82 million after tax for the six months ended June 30, 2016 as compared to $58 million after tax for the same period in 2015.

Duration
A primary objective in the management of the investment portfolio is to optimize return relative to corresponding liabilities and respective liquidity needs. Our views on the current interest rate environment, tax regulations, asset class valuations, specific security issuer and broader industry segment conditions and the domestic and global economic conditions, are some of the factors that enter into an investment decision. We also continually monitor exposure to issuers of securities held and broader industry sector exposures and may from time to time adjust such exposures based on our views of a specific issuer or industry sector.
A further consideration in the management of the investment portfolio is the characteristics of the corresponding liabilities and the ability to align the duration of the portfolio to those liabilities and to meet future liquidity needs, minimize interest rate risk and maintain a level of income sufficient to support the underlying insurance liabilities. For portfolios where future liability cash flows are determinable and typically long term in nature, we segregate investments for asset/liability management purposes. The segregated investments support the long term care and structured settlement liabilities in the Life & Group Non-Core segment.
The effective durations of fixed maturity securities and short term investments are presented in the following table. Amounts presented are net of payable and receivable amounts for securities purchased and sold, but not yet settled.

The investment portfolio is periodically analyzed for changes in duration and related price risk. Additionally, we periodically review the sensitivity of the portfolio to the level of foreign exchange rates and other factors that contribute to market price changes. A summary of these risks and specific analysis on changes is included in the Quantitative and Qualitative Disclosures About Market Risk included under Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2015.

LIQUIDITY AND CAPITAL RESOURCES
Cash Flows
Our primary operating cash flow sources are premiums and investment income from our insurance subsidiaries. Our primary operating cash flow uses are payments for claims, policy benefits and operating expenses, including interest expense on corporate debt. Additionally, cash may be paid or received for income taxes.
For the threesix months ended March 31,June 30, 2016, net cash provided by operating activities was $334$613 million as compared with $94$540 million for the same period in 2015. Cash provided by operating activities reflected increased receipts relating to returns on limited partnerships.
Cash flows from investing activities include the purchase and disposition of available-for-sale financial instruments and may include the purchase and sale of businesses, land, buildings, equipment and other assets not generally held for resale. The cash flow from investing activities is affected by various factors such as the anticipated payment of claims, financing activity, asset/liability management and individual security buy and sell decisions made in the normal course of portfolio management.
Net cash used by investing activities was $9$167 million for the threesix months ended March 31,June 30, 2016, as compared with net cash provided of $526$87 million for the same period in 2015. In the first quarter of 2016, we sold the principal executive offices of CNAF for $107 million.
Cash flows from financing activities may include proceeds from the issuance of debt and equity securities, outflows for stockholder dividends or repayment of debt and outlays to reacquire equity instruments.
For the threesix months ended March 31,June 30, 2016, net cash used by financing activities was $469$538 million as compared with $603$670 million for the same period in 2015. In the first quarter of 2016, we issued $500 million of 4.50% senior notes due March 1, 2026 and redeemed the $350 million outstanding aggregate principal balance of the 6.50% senior notes due August 15, 2016.
Common Stock Dividends
A quarterly dividendDividends of $0.25$2.50 per share andof our common stock, including a special dividend of $2.00 per share, of our common stock were declared and paid induring the first quarter ofsix months ended June 30, 2016. On AprilJuly 29, 2016, our Board of Directors declared a quarterly dividend of $0.25 per share, payable June 1,August 31, 2016 to stockholders of record on May 16,August 15, 2016. The declaration and payment of future dividends to holders of our common stock will be at the discretion of our Board of Directors and will depend on many factors, including our earnings, financial condition, business needs and regulatory constraints.

Liquidity
We believe our present cash flows from operating, investing and financing activities are sufficient to fund our current and expected working capital and debt obligation needs and we do not expect this to change in the near term. There are currently no amounts outstanding under our $250 million senior unsecured revolving credit facility and no borrowings outstanding through our membership in the Federal Home Loan Bank of Chicago (FHLBC).
Dividends from CCC are subject to the insurance holding company laws of the State of Illinois, the domiciliary state of CCC. Under these laws, ordinary dividends, or dividends that do not require prior approval by the Illinois Department of Insurance (the Department), are determined based on the greater of the prior yearsyear's statutory net income or 10% of statutory surplus as of the end of the prior year, as well as timing and amount of dividends paid in the preceding twelve months. Additionally, ordinary dividends may only be paid from earned surplus, which is calculated by removing unrealized gains from unassigned surplus. As of March 31,June 30, 2016 CCC was in a positive earned surplus position. The maximum allowable dividend CCC could pay during 2016 that would not be subject to the Department's prior approval is $1,079 million, less dividends paid during the preceding twelve months measured at that point in time. CCC paid dividends of $300$200 million during the ninesix months ended December 31, 2015 and $565 million during the threesix months ended March 31,June 30, 2016. As of March 31,June 30, 2016 CCC is able to pay approximately $214$314 million of dividends that would not be subject to prior approval of the Department. The actual level of dividends paid in any year is determined after an assessment of available dividend capacity, holding company liquidity and cash needs as well as the impact the dividends will have on the statutory surplus of the applicable insurance company.
We have an effective automatic shelf registration statement under which we may issue debt, equity or hybrid securities.

ACCOUNTING STANDARDS UPDATES
For discussion of Accounting Standards Updates adopted in the current periodas of January 1, 2016 and that will be adopted in the future, see Note A to the Condensed Consolidated Financial Statements.
FORWARD-LOOKING STATEMENTS
This report contains a number of forward-looking statements which relate to anticipated future events rather than actual present conditions or historical events. These statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and generally include words such as “believes,” “expects,” “intends,” “anticipates,” “estimates,” and similar expressions. Forward-looking statements in this report include any and all statements regarding expected developments in our insurance business, including losses and loss reserves for A&EP and other mass tort claims which are more uncertain, and therefore more difficult to estimate than loss reserves respecting traditional property and casualty exposures; the impact of routine ongoing insurance reserve reviews we are conducting; our expectations concerning our revenues, earnings, expenses and investment activities; volatility in investment returns; expected cost savings and other results from our expense reduction activities; and our proposed actions in response to trends in our business. Forward-looking statements, by their nature, are subject to a variety of inherent risks and uncertainties that could cause actual results to differ materially from the results projected in the forward-looking statement. We cannot control many of these risks and uncertainties. These risks and uncertainties include, but are not limited to, the following:
Company-Specific Factors
the risks and uncertainties associated with our insurance reserves, as outlined in the Critical Accounting Estimates and the Reserves - Estimates and Uncertainties sections of our Annual Report on Form 10-K, including the sufficiency of the reserves and the possibility for future increases, which would be reflected in the results of operations in the period that the need for such adjustment is determined;
the risk that the other parties to the transaction in which, subject to certain limitations, we ceded our legacy A&EP liabilities will not fully perform their obligations to CNA, the uncertainty in estimating loss reserves for A&EP liabilities and the possible continued exposure of CNA to liabilities for A&EP claims that are not covered under the terms of the transaction;
the performance of reinsurance companies under reinsurance contracts with us; and
the risks and uncertainties associated with potential acquisitions and divestitures, including the consummation of such transactions, the successful integration of acquired operations and the potential for subsequent impairment of goodwill or intangible assets.
Industry and General Market Factors
the impact of competitive products, policies and pricing and the competitive environment in which we operate, including changes in our book of business;
product and policy availability and demand and market responses, including the level of ability to obtain rate increases and decline or non-renew underpriced accounts, to achieve premium targets and profitability and to realize growth and retention estimates;
general economic and business conditions, including recessionary conditions that may decrease the size and number of our insurance customers and create additional losses to our lines of business, especially those that provide management and professional liability insurance, as well as surety bonds, to businesses engaged in real estate, financial services and professional services and inflationary pressures on medical care costs, construction costs and other economic sectors that increase the severity of claims;
conditions in the capital and credit markets, including continuing uncertainty and instability in these markets, as well as the overall economy, and their impact on the returns, types, liquidity and valuation of our investments;
conditions in the capital and credit markets that may limit our ability to raise significant amounts of capital on favorable terms; and
the possibility of changes in our ratings by ratings agencies, including the inability to access certain markets or distribution channels and the required collateralization of future payment obligations as a result of such changes, and changes in rating agency policies and practices.

Regulatory Factors
regulatory initiatives and compliance with governmental regulations, judicial interpretations within the regulatory framework, including interpretation of policy provisions, decisions regarding coverage and theories of liability, legislative actions that increase claimant activity, trends in litigation and the outcome of any litigation involving us and rulings and changes in tax laws and regulations;
regulatory limitations, impositions and restrictions upon us, including with respect to our ability to increase premium rates, and the effects of assessments and other surcharges for guaranty funds and second-injury funds, other mandatory pooling arrangements and future assessments levied on insurance companies; and
regulatory limitations and restrictions, including limitations upon our ability to receive dividends from our insurance subsidiaries, imposed by regulatory authorities, including regulatory capital adequacy standards.
Impact of Catastrophic Events and Related Developments
weather and other natural physical events, including the severity and frequency of storms, hail, snowfall and other winter conditions, natural disasters such as hurricanes and earthquakes, as well as climate change, including effects on global weather patterns, greenhouse gases, sea, land and air temperatures, sea levels, rain, hail and snow;
regulatory requirements imposed by coastal state regulators in the wake of hurricanes or other natural disasters, including limitations on the ability to exit markets or to non-renew, cancel or change terms and conditions in policies, as well as mandatory assessments to fund any shortfalls arising from the inability of quasi-governmental insurers to pay claims;
man-made disasters, including the possible occurrence of terrorist attacks, the unpredictability of the nature, targets, severity or frequency of such events, and the effect of the absence or insufficiency of applicable terrorism legislation on coverages; and
the occurrence of epidemics.
Referendum on the United Kingdom's Membership in the European Union
on June 23, 2016, the United Kingdom (U.K.) held a referendum in which voters approved an exit from the European Union (E.U.), commonly referred to as "Brexit". As a result of the referendum, it is expected that the British government will formally commence the process to leave the E.U. and begin negotiating the terms of treaties that will govern the U.K.'s future relationship with the E.U. Although it is unknown what those terms will be, it is possible that a U.K. insurance entity's ability to transact insurance business in E.U. countries will be subject to increased regulatory complexities or may not be possible at all. Brexit related changes may adversely affect our operations and financial results.
Our forward-looking statements speak only as of the date on which they are made and we do not undertake any obligation to update or revise any forward-looking statement to reflect events or circumstances after the date of the statement, even if our expectations or any related events or circumstances change.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
There were no material changes in our market risk components for the threesix months ended March 31,June 30, 2016. See the Quantitative and Qualitative Disclosures About Market Risk included in Item 7A on our Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2015 for further information. Additional information related to portfolio duration is discussed in the Investments section of our Management’s Discussion and Analysis of Financial Condition and Results of Operations included in Part I, Item 2.
Item 4. Controls and Procedures
The Company maintains a system of disclosure controls and procedures which are designed to ensure that information required to be disclosed by the Company in reports that it files or submits to the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including this report, is recorded, processed, summarized and reported on a timely basis. These disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed under the Exchange Act is accumulated and communicated to the Company's management on a timely basis to allow decisions regarding required disclosure.
As of March 31,June 30, 2016, the Company's management, including the Company's Chief Executive Officer (CEO) and Chief Financial Officer (CFO), conducted an evaluation of the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Exchange Act Rules 13a-15(e) and 15d-15(e)). Based on this evaluation, the CEO and CFO have concluded that the Company's disclosure controls and procedures are effective as of March 31,June 30, 2016.
There has been no change in the Company’s internal control over financial reporting (as defined in Rules 13a-15 (f) and 15d-15(f) under the Exchange Act) during the quarter ended March 31,June 30, 2016 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
