Non-GAAP and Operating Measures
We believe that investors’ understanding of Allstate’s performance is enhanced by our disclosure of the following non-GAAP and operating 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 income before dividends on preferred securities and 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 acquisition costs (DAC) and deferred sales inducements (DSI), to the extent they resulted from the recognition of certain realized capital gains and losses,

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

adjustments for other significant nonrecurring, 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 as an important measure to evaluate our results of operations. We believe that the measure provides investors with a valuable measure of the Company’s ongoing performance because it reveals trends in our insurance and financial services business that may be obscured by the net effect of realized capital gains and losses, gain (loss) on disposition of operations and adjustments for other significant nonrecurring, infrequent or unusual items. Realized capital gains and losses and gain (loss) on disposition of operations may vary significantly between periods and are generally driven by business decisions and external economic developments such as capital market conditions, the timing of which is unrelated to the insurance underwriting process. Consistent with our intent to protect results or earn additional income, operating income includes periodic settlements and accruals on certain derivative instruments that are reported in realized capital gains and losses because they do not qualify for hedge accounting or are not designated as hedges for accounting purposes. These instruments are used for economic hedges and to replicate fixed income securities, and by including them in operating income, we are appropriately reflecting their trends in our performance and in a manner consistent with the economically hedged investments, product attributes (e.g. net investment income and interest credited to contractholder funds) or replicated investments. Nonrecurring items are excluded because, by their nature, they are not indicative of our business or economic trends. Accordingly, operating income excludes the effect of items that tend to be highly variable from period to period and highlights the results from ongoing operations and the underlying profitability of our business. A byproduct of excluding these items to determine operating income is the transparency and understanding of their significance to net income variability and profitability while recognizing these or similar items may recur in subsequent periods.

Operating income is used by management along with the other components of net income to assess our performance. We use adjusted measures of operating income and operating income per diluted share in incentive compensation. Therefore, we believe it is useful for investors to evaluate net income, operating income and their components separately and in the aggregate when reviewing and evaluating our performance. We note that investors, financial analysts, financial and business media organizations and rating agencies utilize operating income results in their evaluation of our and our industry’s financial performance and in their investment decisions, recommendations and communications as it represents a reliable, representative and consistent measurement of the industry and the Company and management’s performance. We note that the price-to-earnings multiple commonly used by insurance investors as a forward-looking valuation technique uses operating income as the denominator. Operating income should not be considered as a substitute for net income and does not reflect the overall profitability of our business.

The tables below reconcile operating income and net income for the years ended December 31.

Premiums and deposits is an operating measure that we use to analyze production trends for Allstate Financial sales. It includes premiums on insurance policies and annuities, and all deposits and other funds received from customers on deposit-type products including the net new deposits of Allstate Bank, which we account for under GAAP as increases to liabilities rather than as revenue. The tables below illustrate where premiums and deposits are reflected in the consolidated financial statements.

Book value per share, excluding the impact of unrealized net capital gains on fixed income securities, is a ratio that uses a non-GAAP measure. It is calculated by dividing shareholders’ equity after excluding the impact of unrealized net capital gains on fixed income securities and related DAC and life insurance reserves by total shares outstanding plus dilutive potential shares outstanding. Book value per share is the most directly comparable GAAP measure.

We use the trend in book value per share, excluding unrealized net capital gains on fixed income securities, in conjunction with book value per share to identify and analyze the change in net worth attributable to management efforts between periods. We believe the non-GAAP ratio is useful to investors because it eliminates the effect of items that can fluctuate significantly from period to period and are generally driven by economic developments, primarily capital market conditions, the magnitude and timing of which are generally not influenced by management, and we believe it enhances understanding and comparability of performance by highlighting underlying business activity and profitability drivers. We note that book value per share, excluding unrealized net capital gains on fixed income securities, is a measure commonly used by insurance investors as a valuation technique. Book value per share, excluding unrealized net capital gains on fixed income securities, should not be considered as a substitute for book value per share, and does not reflect the recorded net worth of our business. The tables below show the reconciliation.
