Definitions of Non-GAAP and Operating Financial Measures

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

Operating income is income before cumulative effect of change in accounting principle, after-tax, 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 that 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 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 that 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 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 proprietary distribution channel.  New sales of financial products by Allstate exclusive agencies includes annual premiums on new 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 twelve months ended December 31, 2005, 2004 and 2003 totaled est. $2.40 billion, $2.27 billion and $1.83 billion, respectively.
