(c) Premium Revenues and Related Expenses<br />

<strong>Insurance</strong> premiums are earned on a monthly pro rata<br />

basis over the terms <strong>of</strong> the policies and include estimates<br />

<strong>of</strong> audit premiums and premiums on retrospectively<br />

rated policies. Assumed reinsurance premiums are<br />

earned over the terms <strong>of</strong> the reinsurance contracts.<br />

Unearned premiums represent the portion <strong>of</strong> direct and<br />

assumed premiums written applicable to the unexpired<br />

terms <strong>of</strong> the insurance policies and reinsurance contracts<br />

in force.<br />

Ceded reinsurance premiums are charged to income<br />

over the terms <strong>of</strong> the reinsurance contracts. Prepaid<br />

reinsurance premiums represent the portion <strong>of</strong> premiums<br />

ceded to reinsurers applicable to the unexpired<br />

terms <strong>of</strong> the reinsurance contracts in force.<br />

Reinsurance reinstatement premiums are recognized in<br />

the same period as the loss event that gave rise to the<br />

reinstatement premiums.<br />

Acquisition costs that vary with and are primarily<br />

related to the production <strong>of</strong> business are deferred and<br />

amortized over the period in which the related premiums<br />

are earned. Such costs include commissions, premium<br />

taxes and certain other underwriting and policy issuance<br />

costs. Commissions received related to reinsurance pre-<br />

miums ceded are considered in determining net acquisition<br />

costs eligible for deferral. Deferred policy acquisition<br />

costs are reviewed to determine whether they are recoverable<br />

from future income. If such costs are deemed to be<br />

unrecoverable, they are expensed. Anticipated invest-<br />

ment income is considered in the determination <strong>of</strong> the<br />

recoverability <strong>of</strong> deferred policy acquisition costs.<br />

(d) Unpaid Losses and Loss Expenses<br />

Unpaid losses and loss expenses (also referred to as<br />

loss reserves) include the accumulation <strong>of</strong> individual case<br />

estimates for claims that have been reported and estimates<br />

<strong>of</strong> claims that have been incurred but not reported<br />

as well as estimates <strong>of</strong> the expenses associated with<br />

processing and settling all reported and unreported<br />

claims, less estimates <strong>of</strong> anticipated salvage and subrogation<br />

recoveries. Loss reserves are not discounted to<br />

present value.<br />

Reinsurance recoverable on unpaid losses and loss<br />

expenses represents an estimate <strong>of</strong> the portion <strong>of</strong> gross<br />

loss reserves that will be recovered from reinsurers.<br />

Amounts recoverable from reinsurers are estimated in a<br />

manner consistent with the gross losses associated with<br />

the reinsured policies. A provision for estimated uncollectible<br />

reinsurance is recorded based on an evaluation <strong>of</strong><br />

balances due from reinsurers, changes in the credit<br />

standing <strong>of</strong> the reinsurers, coverage disputes and other<br />

relevant factors.<br />

Estimates are based upon past loss experience modiÑed<br />

for current trends as well as prevailing economic, legal<br />

and social conditions. Such estimates are regularly re-<br />

viewed and updated. Any changes in estimates are re-<br />

Öected in operating results in the period in which the<br />

estimates are changed.<br />

(e) Financial Products<br />

Credit derivatives, principally portfolio credit default<br />

swaps, are carried at estimated fair value as <strong>of</strong> the balance<br />

sheet date. Changes in fair value are recognized in in-<br />

come in the period <strong>of</strong> the change and are included in<br />

other revenues.<br />

Assets and liabilities related to the credit derivatives<br />

are included in other assets and other liabilities.<br />

(f) Real Estate<br />

Real estate properties are carried at cost less accumu-<br />

lated depreciation and any writedowns for impairment.<br />

Real estate taxes, interest and other carrying costs in-<br />

curred prior to completion <strong>of</strong> the assets for their in-<br />

tended use are capitalized. Also, costs incurred during<br />

the initial leasing <strong>of</strong> income producing properties are<br />

capitalized until the project is substantially complete,<br />

subject to a maximum time period subsequent to comple-<br />

tion <strong>of</strong> major construction activity.<br />

Real estate properties are reviewed for impairment<br />

whenever events or circumstances indicate that the car-<br />

rying value <strong>of</strong> such properties may not be recoverable. In<br />

performing the review for recoverability <strong>of</strong> carrying<br />

value, estimates are made <strong>of</strong> the future undiscounted<br />

cash Öows from each <strong>of</strong> the properties during the period<br />

the property will be held and upon its eventual disposi-<br />

tion. If the expected future undiscounted cash Öows are<br />

less than the carrying value <strong>of</strong> any property, an impair-<br />

ment loss is recognized, resulting in a writedown <strong>of</strong> the<br />

carrying value <strong>of</strong> the property. Measurement <strong>of</strong> such<br />

impairment is based on the fair value <strong>of</strong> the property.<br />

Rental revenues are recognized on a straight-line basis<br />

over the term <strong>of</strong> the lease. ProÑts on land, residential unit<br />

and commercial building sales are recognized at closing,<br />

subject to compliance with applicable accounting<br />

guidelines.<br />

(g) Investment in Partially Owned Company<br />

Investment in partially owned company includes the<br />

Corporation's 19% interest in a corporate joint venture,<br />

Allied World Assurance Holdings, Ltd. The equity<br />

method <strong>of</strong> accounting is used for this investment.<br />

(h) Goodwill<br />

Goodwill represents the excess <strong>of</strong> the purchase price<br />

over the fair value <strong>of</strong> net assets <strong>of</strong> entities acquired.<br />

Goodwill is tested for impairment at least annually.<br />
