Executive Summary

Financial Results Overview

Net income per diluted share was $0.67 for the first quarter of 2009, compared to $1.02 for the first quarter of 2008. Net income for these same periods was $32.7 million and $50.3 million, respectively. Results for the first quarter of 2009 reflected after-tax net capital losses of $17.3 million compared to after-tax net capital losses of $2.8 million for the first quarter of 2008. In addition, the Company recorded after-tax one-time costs in operating expenses for the first quarter of 2009 of $5.4 million associated with severance and lease terminations related to operating efficiency projects. Results for the first quarter of 2009 reflect comparatively favorable claims experience for the group insurance and individual disability insurance businesses, partially offset by comparatively lower premiums for the group insurance businesses and comparatively lower administrative fee revenue from the Asset Management segment resulting from the impact of declining equity markets on asset-based fees.

Outlook

General economic conditions remain turbulent and reflect a disruption of both credit and equity markets. While we are not immune to the current economic turbulence, we will continue to focus on our long-term objectives and address challenges that arise with financial discipline and from a position of financial strength.

We manage for profitability, focusing on good business diversification, disciplined product pricing, sound underwriting, effective claims management and high-quality customer service. In 2009, our intent is to preserve the value of our business by continuing to provide excellent value to our customers, to preserve and enhance our financial strength by remaining disciplined in our approach, and to continue to build value for our shareholders despite facing the headwinds of a troubled economy. Through the implementation of our current operating efficiency initiatives, we are positioning ourselves for growth as economic conditions improve.

During the first quarter of 2009, we have experienced a group insurance market that continues to reflect a price-competitive sales environment. In addition, we continue to experience a decline in revenues in our retirement plans business due to declines in equity markets and their impact on asset values, which is a key driver in administrative fee revenue. Despite these challenges, we continue to experience positive net cash flows in our Retirement Plans business, and retention in our group insurance business remains consistent with our retention over the last several years. Although we have experienced some losses in our fixed maturity securities investment portfolio, our mortgage loan portfolio continues to perform well despite a challenging economic environment. Over the past twelve months we have seen delinquency rates rise, which is expected given the economy, however we have not seen the delinquency rates or foreclosures that have been experienced by other financial institutions, including those that participate in the commercial mortgage backed securities market place. We point to our long history in the commercial mortgage loan business and our attention to disciplined underwriting at origination, which explains our comparatively favorable experience. We believe that our vast experience combined with our track record of superior performance in this asset class during previous recessions will serve us well given current economic conditions.

For 2009, the Company has established the following expectations, which will affect our annual financial results:

• Return on average equity, excluding after-tax net capital gains and losses from net income and accumulated other comprehensive income and losses from equity, will be within the target range of 14% to 15%.

• Revenues are likely to be relatively flat compared to 2008 given the challenging economic environment.

• The annual benefit ratio for the group insurance business will be consistent with the experience of the previous five years, during which it has ranged from 73.6% to 78.3%.

• Expenses for our employee pension plans will increase by approximately $10 million over 2008 as a result of declines in equity values experienced during 2008.

• We will diligently manage operating expenses in response to changing market conditions. One-time costs of $15 million to $20 million will be experienced in 2009 and will be associated with projects designed to enhance our operating efficiencies and reduce our annualized operating expenses by approximately $25 million per year beginning in the second half of 2009.

Consolidated Results of Operations

Revenues

Revenues consist of premiums, administrative fees, net investment income and net capital gains and losses. Total revenues of $686.0 million remained relatively flat for the first quarter of 2009, compared to $692.8 million for the first quarter of 2008. Historically, premiums in our Insurance Services segment and administrative fees in our Asset Management segment have been the primary drivers of consolidated revenue growth. During the first quarter of 2009, premiums in our Insurance Services segment and net investment income in our Asset Management segment were the primary drivers of revenue growth.

Revenue in the Insurance Services segment and Asset Management segment showed modest growth in the first quarter of 2009. Revenue growth in the Insurance Services segment was primarily due to an approximately $18 million premium related to the termination of reinsurance agreements for individual disability insurance. The

Asset Management segment revenue was driven by an increase in net investment income due to increased levels of individual annuity assets under administration, which was partially offset by a decline in administrative fee revenue due to the impact of declining equity markets on asset based fee revenue. In addition, growth in the Insurance Services and Asset Management segment was offset by capital losses recorded in the Other category.

The following table sets forth percentages of premium growth, administrative fee growth and net investment income growth by segment:

                                                            For the

    Consolidated revenue growth                          (1.0 )             7.8

Revenue growth in the Insurance Services and Asset Management segments was offset by net capital losses of $26.7 million for the first quarter of 2009 compared to net capital losses of $4.4 million for the first quarter of 2008. Net capital losses are reflected in the Other category.

Premiums

Premiums from our Insurance Services segment are the primary driver of consolidated premium growth. The three primary factors that influence premium growth for our Insurance Services segment are sales, customer retention, and organic growth derived from wage and employment growth. Premiums for the Insurance Services segment increased 1.6% to $542.9 million for the first quarter of 2009, compared to the same period in 2008. The increase in premiums was primarily due to an approximately $18 million premium related to the termination of reinsurance agreements for individual disability insurance in the first quarter of 2009, compared to a $3.7 million premium related to the termination of a reinsurance agreement that occurred in the first quarter of 2008. The increase in premiums from the termination of reinsurance agreements was offset by a slight decrease in premiums from our group insurance business primarily due to the loss of a few large groups during the second and third quarters of 2008. See "Business Segments-Insurance Services Segment."

Premiums from our Asset Management segment are primarily generated from life-contingent annuities, which are a single-premium product. Due to the nature of single premium products, premiums in the Asset Management segment can fluctuate widely from quarter to quarter. Premiums for the Asset Management segment decreased 66.1% to $2.1 million for the first quarter of 2009 compared to the first quarter of 2008.

Administrative Fees

The primary driver for administrative fee revenue is the level of assets under administration in our Asset Management segment, which is primarily driven by equity market performance. Administrative fees for our Asset Management segment decreased 11.5% to $25.5 million for the first quarter of 2009 compared to the same period in 2008. The comparative decrease in administrative fee revenue in our Asset Management segment was due to lower levels of assets managed or administered for retirement accounts, which was the result of declining equity markets. This was partially offset by growth in net customer deposits in retirement plans. See "Business Segments-Asset Management Segment."

Administrative fee revenue from our Insurance Services segment is primarily from insurance products for which we provide only administrative services. Administrative fee revenue from our Insurance Services segment decreased 13.0% to $2.0 million for the first quarter of 2009 compared to the first quarter of 2008.

Net Investment Income

Net investment income increased 11.4% to $143.5 million for the first quarter of 2009 compared to the first quarter of 2008. Net investment income is affected primarily by changes in levels of invested assets, interest rates, the change in fair value of derivative assets and commercial mortgage loan prepayment fees.

The increase in net investment income for the first quarter of 2009 compared to the same period in 2008 was primarily due to an increase of 6.8% in average invested assets to $9.52 billion, primarily resulting from additional individual annuity assets under administration. Average invested assets do not include cash and cash equivalents. Also contributing to the increase were higher average yields in our fixed maturity securities and commercial loan portfolios. Portfolio yields for our fixed maturity securities and commercial mortgage loan portfolios increased to 5.61% and 6.38% respectively, at March 31, 2009, compared to 5.54% and 6.36% respectively, at March 31, 2008. Also affecting net investment income was the fair value adjustment to derivative assets which was a decrease of $1.4 million for the first quarter of 2009, compared to a decrease of $4.9 million for the first quarter of 2008. The increase in net investment income was partially offset by a decrease in commercial mortgage loan prepayment fees. Commercial mortgage loan prepayment fees were $0.6 million for the first quarter of 2009, compared to $1.8 million for the first quarter of 2008.

Net Capital Gains (Losses)

Net capital gains and losses are reported in Other. Net capital losses were $26.7 million for the first quarter of 2009, compared to $4.4 million for the first quarter of 2008. Net capital gains and losses occur as a result of other-than-temporary impairments ("OTTI") or sales of the Company's assets for less than the amortized cost, neither of which is likely to occur in regular patterns. The net capital losses in the first quarter of 2009 were primarily due to the sale of certain fixed maturity securities. Approximately $14.2 million of the capital losses were due to bond sales related primarily to holdings in financial institutions, particularly insurance companies which were downgraded by rating agencies during the current period, and $3.3 million was the result of other-than-temporary bond impairments.

Benefits and Expenses

Benefits to Policyholders

Benefits to policyholders are affected by four primary factors: reserves that are established in part based on premium levels, claims experience, assumptions used to establish related reserves and current estimates for future benefits of life-contingent annuities. The predominant factors affecting claims experience are incidence measured by the number of claims, and severity measured as the length of time a disability claim is paid and the size of the claim. The assumptions used to establish the related reserves reflect expected incidence and severity, as well as new investment interest rates and overall portfolio yield, both of which affect the discount rate used to establish reserves. See "Critical Accounting Policies and Estimates-Reserves."

Benefits to policyholders increased 0.2% to $412.5 million for the first quarter of 2009 compared to the same period in 2008. The increase was primarily due to the termination of reinsurance contracts in the first quarter of 2009 and 2008, where the Company assumed risk previously ceded and therefore increased reserves by approximately $18 million and $3.9 million, respectively. Excluding the impact of the termination of reinsurance, benefits to policyholders decreased 3.5% for the first quarter of 2009. See "Business Segments-Insurance Services Segment-Benefits and Expenses-Benefits to Policyholders."

Benefits to policyholders for the Asset Management segment decreased 42.2% to $4.8 million for the first quarter of 2009 compared to the same period in 2008. This was primarily due to lower sales of life contingent annuities in the first quarter of 2009 compared to the same period in 2008. Life-contingent annuities are primarily a single-premium product, and for that reason, activity can fluctuate widely from quarter to quarter.

Interest Credited

Interest credited represents interest paid to policyholders on retirement plan general account assets and individual fixed annuity deposits in the Asset Management segment and interest paid on life insurance proceeds on deposit in the Insurance Services segment. The primary factors that affect interest credited are growth in general account assets under administration, new investment interest rates and overall portfolio yield (which influence our interest crediting rate for our customers), and customer retention. In addition, interest credited associated with our indexed annuity product may fluctuate from quarter to quarter due to changes in interest rates and equity market volatility.

Consolidated interest credited increased to $34.0 million for the first quarter of 2009, compared to $21.2 million for the first quarter of 2008. The increase was primarily due to growth in average individual annuity assets under administration of 53.7% to $2.09 billion from higher levels of sales in 2008.

Operating Expenses

Operating expenses increased 8.0% to $126.2 million for the first quarter of 2009 compared to the same period of 2008. The increase was primarily due to one-time costs of $8.4 million, primarily related to severance costs and lease terminations. In 2009, the Company expects to incur one-time costs of $15 to $20 million associated with projects that will enhance the Company's operating efficiencies and reduce its annualized operating expense run rate by approximately $25 million beginning in the second half of 2009. See "Business Segments."

Commissions and Bonuses

Commissions and bonuses primarily represent sales-based compensation, which can vary depending on the product, the structure of the commission program and factors such as customer retention, sales, growth in assets under administration and profitability of the business in each of our segments. Commissions and bonuses decreased 4.5% to $54.6 million for the first quarter of 2009 compared to the same period in 2008. The decrease primarily was due to lower assets under administration in our retirement plans business, lower sales in our individual annuity business and a reduction in premium revenue in our group insurance businesses. See "Business Segments."

Net Increase in Deferred Acquisition Costs ("DAC"), Value of Business Acquired ("VOBA") and Intangibles

We defer certain commissions, bonuses and operating expenses, which are considered acquisition costs. These costs are then amortized into expenses over a period not to exceed the life of the related policies, which for group insurance contracts is the initial premium rate guarantee period, which averages 2.5 years. VOBA primarily represents the discounted future profits of business assumed through reinsurance agreements. A portion

of VOBA is amortized each year to achieve matching against expected gross profits. The Company's intangibles, consisting of customer lists and marketing agreements, are also subject to amortization. Customer lists were obtained through acquisitions and are amortized over 10 years. The amortization for the marketing agreement with the Minnesota Life Insurance Company ("Minnesota Life") is up to 25 years. See "Critical Accounting Policies and Estimates-Deferred Acquisition Costs ("DAC"), Value of Business Acquired ("VOBA") and Other Intangible Assets." The net deferral for DAC, VOBA and intangibles for the first quarter of 2009 decreased $0.4 million compared to the same period of 2008.

Income Taxes

Income taxes may differ from the amount computed by applying the federal corporate tax rate of 35% to pre-tax income because of the net result of permanent differences between book and taxable income and because of the inclusion of state and local income taxes, net of the federal tax benefit. The combined federal and state effective income tax rates were 33.4% and 33.9% for the first quarters of 2009 and 2008, respectively. At March 31, 2009, the years open for audit by the Internal Revenue Service ("IRS") were 2005 through 2008. The federal statute of limitations for the 2004 tax year expired in September 2008.

Business Segments

StanCorp operates through two reportable segments: Insurance Services and Asset Management, as well as an Other category, which includes net capital gains and losses, return on capital not allocated to the product segments, holding company expenses, interest on debt, unallocated expenses including one-time costs and adjustments made in consolidation. Resources are allocated and performance is evaluated at the segment level. The Insurance Services segment offers group and individual disability insurance, group life and accidental death and dismemberment ("AD&D") insurance, and group dental insurance. The Asset Management segment offers full-service 401(k) plans, 457 plans, defined benefit plans, money purchase pension plans, profit sharing plans, 403(b) plans and non-qualified deferred compensation products and services through an affiliated broker-dealer. This segment also offers investment advisory and management services, financial planning services, commercial mortgage loan origination and servicing, individual fixed annuities, group annuity contracts and retirement plan trust products.

The following table sets forth segment revenues measured as a percentage of total revenues, excluding net capital losses:

                                           Three Months Ended
                                                March 31,

                    Insurance Services       88.1 %         88.9 %
                    Asset Management         11.5           10.7

Insurance Services Segment

The Insurance Services segment is our largest segment and substantially influences our consolidated financial results. Income before income taxes for the Insurance Services segment was $86.0 million for the first quarter of 2009, compared to $78.9 million for the first quarter of 2008. Results for the first quarter of 2009 reflected comparatively favorable claims experience for the group insurance and individual disability insurance businesses, partially offset by comparatively lower premiums for the group insurance businesses.

The following are key indicators that management uses to manage and assess the performance of the Insurance Services segment:

                                                                         For the

Revenues

Revenues for the Insurance Services segment increased 1.3% to $627.8 million for the first quarter of 2009 compared to the same period in 2008. Revenue growth was primarily due to premium growth, which was affected by an approximately $18 million premium related to the termination of reinsurance agreements for individual disability insurance, partially offset by slightly lower administrative fee revenue.

Premiums

Premiums for the Insurance Services segment increased 1.6% to $542.9 million for the first quarter of 2009 compared to the same period in 2008. Premiums for the first quarters of 2009 and 2008 included approximately $18 million and $3.7 million, respectively related to termination of reinsurance agreements. The primary factors that affect premium growth for the Insurance Services segment are sales and persistency for all of our insurance products and organic growth in our group insurance product lines primarily due to employment and wage rate growth from existing group policyholders.

Sales. Sales of our group insurance products reported as annualized new premiums were $100.1 million and $120.8 million for the first quarters of 2009 and 2008, respectively. The group insurance market continues to reflect a price-competitive sales environment.

Persistency. Annual persistency for our group insurance products has historically exceeded industry averages. We believe this demonstrates our commitment to customer service and pricing discipline for new sales. Persistency is reported annually. Premium growth for the first quarter of 2009 was affected by the loss of a few large group customers during the second quarter of 2008, which also impacted annual persistency in 2008.

Organic Growth. A portion of our premium growth in our group insurance in force . . .
