Summary of Significant Accounting Policies

(1)  Summary of Significant Accounting Policies

 

(a) Basis of Presentation

The Chubb Corporation (Chubb) is a holding company with subsidiaries principally engaged in the property and casualty insurance business. The property and casualty insurance subsidiaries (the P&C Group) underwrite most lines of property and casualty insurance in the United States, Canada, Europe, Australia and parts of Latin America and Asia. The geographic distribution of property and casualty business in the United States is broad with a particularly strong market presence in the Northeast.

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and include the accounts of Chubb and its subsidiaries (collectively, the Corporation). Significant intercompany transactions have been eliminated in consolidation. The results of our operations in Australia, Brazil and other smaller foreign locations are recorded on a three month lag in our consolidated financial statements. Specific events having significant financial impact that occur during the lag period are included in the current period results.

The consolidated financial statements include amounts based on informed estimates and judgments of management for transactions that are not yet complete. Such estimates and judgments affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Certain amounts in the consolidated financial statements for prior years have been reclassified to conform with the 2014 presentation.

 

(b) Invested Assets

Short term investments, which have an original maturity of one year or less, are carried at amortized cost, which approximates fair value.

Fixed maturities, which include taxable and tax exempt bonds, are classified as available-for-sale and carried at fair value as of the balance sheet date. Taxable bonds include U.S. government and government agency and authority obligations, including taxable bonds issued by states, municipalities and political subdivisions within the United States, and foreign government and government agency obligations, corporate bonds and mortgage-backed securities. Corporate bonds include redeemable preferred stocks. Tax exempt bonds consist of bonds issued by states, municipalities and political subdivisions within the United States. Fixed maturities are purchased to support the investment strategies of the Corporation. These strategies are developed based on many factors including rate of return, maturity, credit risk, tax considerations and regulatory requirements. Fixed maturities may be sold prior to maturity to support the investment strategies of the Corporation.

Premiums and discounts arising from the purchase of fixed maturities are amortized using the interest method over the estimated remaining term of the securities. For mortgage-backed securities, prepayment assumptions are reviewed periodically and revised as necessary.

Equity securities, which include common stocks and non-redeemable preferred stocks, are carried at fair value as of the balance sheet date.

Unrealized appreciation or depreciation, including unrealized other-than-temporary impairment losses, of fixed maturities and equity securities carried at fair value is excluded from net income and is included, net of applicable deferred income tax, in other comprehensive income.

 

Other invested assets primarily include private equity limited partnerships, which are carried at the Corporation’s equity in the net assets of the partnerships based on valuations provided by the manager of each partnership. As a result of the timing of the receipt of valuation data from the investment managers, these investments are generally reported on a three month lag. Changes in the Corporation’s equity in the net assets of the partnerships are included in net income as realized investment gains or losses. Other invested assets also include warrants, which are carried at fair value as of the balance sheet date. Changes in the fair value of warrants are included in net income as realized investment gains or losses.

Realized gains and losses on the sale of investments are determined on the basis of the cost of the specific investments sold and are included in net income.

When the fair value of an investment is lower than its cost, an assessment is made to determine whether the decline is temporary or other than temporary. The assessment of other-than-temporary impairment of fixed maturities and equity securities is based on both quantitative criteria and qualitative information. A number of factors are considered including, but not limited to, the length of time and the extent to which the fair value has been less than the cost, the financial condition and near term prospects of the issuer, whether the issuer is current on contractually obligated interest and principal payments, general market conditions and industry or sector specific factors.

In determining whether fixed maturities are other than temporarily impaired, the Corporation is required to recognize an other-than-temporary impairment loss when it concludes it has the intent to sell or it is more likely than not it will be required to sell an impaired fixed maturity before the security recovers to its amortized cost value or it is likely it will not recover the entire amortized cost value of an impaired security. If the Corporation has the intent to sell or it is more likely than not that the Corporation will be required to sell an impaired fixed maturity before the security recovers to its amortized cost value, the security is written down to fair value and the entire amount of the writedown is included in net income as a realized investment loss. For all other impaired fixed maturities, when the impairment is determined to be other than temporary, the impairment loss is separated into the amount representing the credit loss and the amount representing the loss related to all other factors. The amount of the impairment loss that represents the credit loss is included in net income as a realized investment loss and the amount of the impairment loss that relates to all other factors is included in other comprehensive income.

For fixed maturities, the split between the amount of other-than-temporary impairment losses that represents credit losses and the amount that relates to all other factors is principally based on assumptions regarding the amount and timing of projected cash flows. For fixed maturities other than mortgage-backed securities, cash flow estimates are based on assumptions regarding the probability of default and estimates regarding the timing and amount of recoveries associated with a default. For mortgage-backed securities, cash flow estimates are based on assumptions regarding future prepayment rates, default rates, loss severity and timing of recoveries. The Corporation has developed the estimates of projected cash flows using information based on historical market data, industry analyst reports and forecasts and other data relevant to the collectibility of a security.

In determining whether equity securities are other than temporarily impaired, the Corporation considers its intent and ability to hold a security for a period of time sufficient to allow for the recovery of cost. If the decline in the fair value of an equity security is deemed to be other than temporary, the security is written down to fair value and the amount of the writedown is included in net income as a realized investment loss.

 

(c) Premium Revenues and Related Expenses

Insurance premiums are earned on a monthly pro rata basis over the terms of the policies and include estimates of audit premiums and premiums on retrospectively rated policies. Assumed reinsurance premiums are earned over the terms of the reinsurance contracts. Unearned premiums represent the portion of direct and assumed premiums written applicable to the unexpired terms of the insurance policies and reinsurance contracts in force.

Ceded reinsurance premiums are reflected in operating results over the terms of the reinsurance contracts. Prepaid reinsurance premiums represent the portion of premiums ceded to reinsurers applicable to the unexpired terms of the reinsurance contracts in force.

Reinsurance reinstatement premiums are recognized in the same period as the loss event that gave rise to the reinstatement premiums.

Acquisition costs that are directly related to the successful acquisition of new or renewal insurance contracts are deferred and amortized over the period in which the related premiums are earned. Such costs include commissions, premium taxes and certain other underwriting and policy issuance costs. Commissions received related to reinsurance premiums ceded are considered in determining net acquisition costs eligible for deferral. Deferred policy acquisition costs are reviewed to determine whether they are recoverable from future income. If such costs are deemed to be unrecoverable, they are expensed. Anticipated investment income is considered in the determination of the recoverability of deferred policy acquisition costs.

 

(d) Unpaid Losses and Loss Expenses

Unpaid losses and loss expenses (also referred to as loss reserves) include the accumulation of individual case estimates for claims that have been reported and estimates of claims that have been incurred but not reported as well as estimates of the expenses associated with processing and settling all reported and unreported claims, less estimates of anticipated salvage and subrogation recoveries. Estimates are based upon past loss experience modified for current trends as well as prevailing economic, legal and social conditions. Loss reserves are not discounted to present value.

Loss reserves are regularly reviewed using a variety of actuarial techniques. Reserve estimates are updated as historical loss experience develops, additional claims are reported and/or settled and new information becomes available. Any changes in estimates are reflected in operating results in the period in which the estimates are changed.

Reinsurance recoverable on unpaid losses and loss expenses represents an estimate of the portion of gross loss reserves that will be recovered from reinsurers. Amounts recoverable from reinsurers are estimated using assumptions that are consistent with those used in estimating the gross losses associated with the reinsured policies. A provision for estimated uncollectible reinsurance is recorded based on periodic evaluations of balances due from reinsurers, the financial condition of the reinsurers, coverage disputes and other relevant factors.

 

(e) Financial Products

Derivatives are carried at fair value as of the balance sheet date. Changes in fair value are recognized in net income in the period of the change and are included in other revenues.

Assets and liabilities related to these derivatives are included in other assets and other liabilities.

 

(f) Goodwill

Goodwill represents the excess of the cost of an acquired entity over the fair value of net assets acquired. Goodwill is tested for impairment at least annually.

 

(g) Property and Equipment

Property and equipment used in operations, including certain costs incurred to develop or obtain computer software for internal use, are capitalized and carried at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. Property and equipment are included in other assets.

 

(h) Real Estate

Real estate properties are carried at cost less accumulated depreciation and any writedowns for impairment. Real estate properties are reviewed for impairment whenever events or circumstances indicate that the carrying value of such properties may not be recoverable. Measurement of such impairment is based on the fair value of the property. Real estate properties are included in other assets.

 

(i) Income Taxes

Deferred income tax assets and liabilities are recognized for the expected future tax effects attributable to temporary differences between the financial reporting and tax bases of assets and liabilities, based on enacted tax rates and other provisions of tax law. The effect on deferred tax assets and liabilities of a change in tax laws or rates is recognized in net income in the period in which such change is enacted. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that all or some portion of the deferred tax assets will not be realized.

The Corporation does not consider the earnings of its foreign subsidiaries to be permanently reinvested. Accordingly, provision has been made for the expected U.S. federal income tax liabilities applicable to undistributed earnings of foreign subsidiaries.

 

(j) Stock-Based Employee Compensation

The fair value method of accounting is used for stock-based employee compensation plans. Under the fair value method, compensation cost is measured based on the fair value of the award at the grant date and recognized over the requisite service period.

 

(k) Foreign Exchange

Assets and liabilities relating to foreign operations are translated into U.S. dollars using current exchange rates as of the balance sheet date. Revenues and expenses are translated into U.S. dollars using the average exchange rates during the year.

The functional currency of foreign operations is generally the currency of the local operating environment since business is primarily transacted in such local currency. Translation gains and losses, net of applicable income tax, are excluded from net income and are credited or charged directly to other comprehensive income.

 

(l) Cash Flow Information

In the statement of cash flows, short term investments are not considered to be cash equivalents. The effect of changes in foreign exchange rates on cash balances was insignificant.

In 2013, the Corporation exchanged its holdings of common stock and warrants of Alterra Capital Holdings Limited, with a cost basis of $177 million and a carrying value of $63 million, respectively, for common stock of Markel Corporation, valued at $226 million, and cash of $98 million, as a result of a business combination. The noncash portions of the transaction have been excluded from the statement of cash flows.
