Definitions of Non-GAAP and Operating Measures

We believe that investors’ understanding of our performance is enhanced by our disclosure of the following non-GAAP financial measures. Our methods of calculating these measures may differ from those used by other companies and therefore comparability may be limited.

Operating income is net income excluding:

•                  realized capital gains and losses, after-tax, except for periodic settlements and accruals on non-hedge derivative instruments which are reported with realized capital gains and losses but included in operating income,

•                  amortization of deferred policy acquisition costs (“DAC”) and deferred sales inducements (“DSI”), to the extent they resulted from the recognition of certain realized capital gains and losses,

•                  (loss) gain on disposition of operations, after-tax, and

•                  adjustments for other significant non-recurring, infrequent or unusual items, when (a) the nature of the charge or gain is such that it is reasonably unlikely to recur within two years, or (b) there has been no similar charge or gain within the prior two years.

Net income is the GAAP measure that is most directly comparable to operating income.

We use operating income to evaluate our results of operations. It reveals trends in our insurance and financial services business that may be obscured by the net effect of realized capital gains and losses, (loss) gain on disposition of operations and adjustments for other significant non-recurring, infrequent or unusual items. Realized capital gains and losses and (loss) gain on disposition of operations may vary significantly between periods and are generally driven by business decisions and economic developments such as market conditions, the timing of which is unrelated to the insurance underwriting process. Moreover, we reclassify periodic settlements on non-hedge derivative instruments into operating income to report them in a manner consistent with the economically hedged investments, replicated assets or product attributes (e.g. net investment income and interest credited to contractholder funds) and by doing so, appropriately reflect trends in product performance. Non-recurring items are excluded because, by their nature, they are not indicative of our business or economic trends. Therefore, we believe it is useful for investors to evaluate these components separately and in the aggregate when reviewing our performance. We use adjusted measures of operating income in incentive compensation. Operating income should not be considered as a substitute for net income and does not reflect the overall profitability of our business.

The following table reconciles operating income and net income.

Operating income return on equity is a ratio that uses a non-GAAP measure. It is calculated by dividing the rolling 12-month operating income by the average of shareholder’s equity at the beginning and at the end of the 12-month period, after excluding the effect of unrealized net capital gains. We use it to supplement our evaluation of net income and return on equity. We believe that this measure is useful to investors because it eliminates the effect of items that can fluctuate significantly from period to period and that are driven by economic developments, the magnitude and timing of which are generally not influenced by management:  the after-tax effects of realized and unrealized capital gains and losses and the cumulative effect of change in accounting principle, and non-recurring items that are not indicative of our business or economic trends. Return on equity is the most directly comparable GAAP measure.  The following table shows the reconciliation.

Operating Measures

We believe that investors’ understanding of our performance is enhanced by our disclosure of the following operating financial measures. Our method of calculating these measures may differ from those used by other companies and therefore comparability may be limited.

Premiums and deposits is an operating measure that we use to analyze production trends for sales. It includes premiums on insurance policies and annuities and all deposits and other funds received from customers on deposit-type products, which we account for under GAAP as increases to liabilities rather than as revenue.

The following table illustrates where premiums and deposits are reflected in the condensed consolidated financial statements.

New sales of financial products by Allstate exclusive agencies is an operating measure that we use to quantify the current year sales of financial products by the Allstate Agency proprietary distribution channel. New sales of financial products by Allstate exclusive agencies includes annual premiums on new life insurance policies, initial premiums and deposits on annuities, net new deposits in the Allstate Bank, sales of other companies’ mutual funds, and excludes renewal premiums. New sales of financial products by Allstate exclusive agencies for the first quarter of 2006 and 2005 totaled est. $539 million and $514 million, respectively, or an increase of 4.9%.
