partnerships. Individually, the interests in these partnerships do not represent a significant variable interest pursuant to the definition of Financial Accounting Standards Board (FASB) Interpretation No. 46(R), Consolidation of
Variable Interest Entities, (revised December 2003)an interpretation of ARB No. 51, nor do they meet the requirements for consolidation. The total investment in these interests was $17.4 million and $17.8 million at March 31,
2008, and December 31, 2007, respectively.

Minority interest related to consolidated entities included in other liabilities was $0.6

The unaudited consolidated financial statements include
StanCorp and its subsidiaries. Intercompany balances and transactions have been eliminated.

The accompanying unaudited consolidated
financial statements of StanCorp and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and in conformance with the
requirements of Form 10-Q pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and disclosures required by GAAP for complete financial statements. The preparation of financial statements in
conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the financial statement date, and the reported amounts of
revenues and expenses during the period. Actual results may differ from those estimates. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal recurring accruals,
considered necessary for a fair presentation of the Companys financial condition at March 31, 2008, and for the results of operations for the three months ended March 31, 2008 and 2007, and cash flows for the three months ended
March 31, 2008 and 2007. Interim results for the three-month period ended March 31, 2008, are not necessarily indicative of the results that may be expected for the year ending December 31, 2008. This report should be read in
conjunction with the Companys 2007 annual report on Form 10-K.



|2. | NET INCOME PER COMMON SHARE
|-- | ---------------------------

Basic net income per
common share was calculated by dividing net income by the weighted-average number of common shares outstanding. Net income per diluted common share, as calculated using the treasury stock method, reflects the potential dilutive effects of restricted
stock grants and exercises of dilutive outstanding stock options. The computation of diluted weighted-average earnings per share does not include stock options with an option exercise price greater than the average market price because they are
antidilutive and inclusion would increase earnings per share.

|3. | SHARE-BASED COMPENSATION
|-- | ------------------------

The Company has three
share-based compensation plans: the 1999 Omnibus Stock Incentive Plan, the 2002 Stock Incentive Plan and the 1999 Employee Share Purchase Plan (ESPP).

The 1999 Omnibus Stock Incentive Plan authorized the board of directors of StanCorp to grant eligible employees certain incentive or non-statutory stock options, bonuses and performance stock options, restricted and
foreign stock awards, and stock appreciation and cash bonus rights related to StanCorps common stock. The maximum number of shares of common stock that may be issued under this plan is 3.4 million. Substantially all of these shares have been
issued or optioned.

The 2002 Stock Incentive Plan authorized the board of directors to grant eligible employees and certain related
parties incentive or non-statutory stock options and restricted stock. The maximum number of shares of common stock that may be issued under this plan is 2.9 million. At March 31, 2008, 2.5 million shares or options for shares had been
issued under the 2002 plan. At the May 5, 2008 annual meeting of shareholders, the shareholders approved amending the plan to increase the number of shares available by 1.9 million shares.

The Companys ESPP allows eligible employees to purchase StanCorp common stock at a discount. The ESPP is described later in this section.

Income before income taxes included compensation cost related to all share-based compensation arrangements of $3.4 million and $2.8
million for the first quarters of 2008 and 2007, respectively. The related tax benefits were $1.2 million and $1.0 million for the same periods, respectively.

The Company has provided three types of share-based compensation pursuant to the 1999 Omnibus Stock Incentive Plan and the 2002 Stock Incentive Plan: option grants to directors, officers and certain non-officer
employees; restricted stock grants to officers; and stock retainer fees to directors.

Option Grants

Options are granted to directors, officers and certain non-officer employees. Directors and executive officers receive annual grants in amounts determined
by the organization and compensation committee of the board of directors. Officers may also receive options when hired or promoted to an officer position. In addition, the chief executive officer has authority to award a limited number of options at
his discretion to non-executive officers

and other employees. Options are granted with an exercise price equal to the market closing price of the stock on the date of grant. Directors options
vest in one year with all others vesting in four equal installments on the first four anniversaries of the grant date. Option awards to certain officers vest immediately upon a change of control of the Company as defined in the change of control
agreement. Options generally expire 10 years from the grant date.

A summary of option activity and options outstanding and exercisable is
presented below:

The fair value of each option award under the share-based compensation plans was estimated using
the Black-Scholes option-pricing model as of the grant date using the assumptions noted in the following table. The Black-Scholes model uses the expected term as an input, with the calculated option value varying directly with the length of time
until exercise. The Company bases its estimate of expected term on an analysis of the historical exercise experience of similar options granted to similar employee or director groups. The expected term given below represents the weighted-average
expected term of options granted. Expected stock price volatility was based on volatility of the Companys stock over the prior period equal in duration to the expected term. The dividend rate is the rate expected to be paid over the expected
term, generally estimated to be equal to the rate for the year prior to the grant. The risk-free rate is the interest rate on a U.S. Treasury bond of a maturity closest to the expected term of the option.

The weighted-average grant date fair value of options granted was $11.95 during the first quarter
of 2008, compared to $11.36 during the first quarter of 2007. The total intrinsic value of the options exercised was $0.7 million for both the first quarters of 2008 and 2007. The amount received from the exercise of stock options was $0.9 million
for the first quarter of 2008, compared to $0.7 million for the first quarter of 2007. The related tax benefit derived from the tax deduction received by the Company for the difference between the stock price and the exercise price when the options
were exercised was $0.3 million for both the first quarters of 2008 and 2007.

The expense of stock options is amortized over the vesting period, which is also the period over which
the grantee must provide services to the Company. At March 31, 2008, the total compensation cost related to unvested option awards that has not yet been recognized in the financial statements was $8.1 million. This cost will be recognized over
the next four years.

Restricted Stock Grants

Restricted stock grants are a part of the Companys long-term compensation for certain senior officers. The Company grants both performance-based and retention-based restricted stock. Under the current plans, the Company had
0.4 million shares available for issuance as restricted stock at March 31, 2008.

Performance-based Restricted Stock

Performance-based awards are made to designated officers each year and vest with respect to all or a portion of the awards based on
the Companys financial performance for a given year. In years prior to 2007, awards consisted of restricted stock (60%) and cash performance units (40%), which represent a right to receive cash equal to the value of one share of stock
subject to the same employment and performance criteria. Both restricted stock and cash performance units are subject to forfeiture if continued employment and financial performance criteria are not met.

On December 8, 2006, the organization and compensation committee of the board of directors of StanCorp approved a revised form of long-term
incentive award agreement to be used in connection with future grants of performance-based awards to executives (Stock Performance Units). Under the new agreement, Stock Performance Units granted represent the maximum number of shares to
be issued and Units are generally granted two years before the performance period. Stock is issued at the end of the performance period based on satisfaction of employment and financial performance conditions, with a portion of the shares withheld
to cover required tax withholding. The new agreement replaces the restricted stock and cash performance unit arrangement previously used.

The compensation cost of these awards was measured using an estimate of the number of shares of StanCorp stock that will vest at the end of the performance period, multiplied by the fair market value. For shares, the fair market value was
measured at the grant date. For cash units, the value was measured as of the date of the financial statements.

A summary of the activity
for Stock Performance Units outstanding is presented below:

During the first quarters of 2008 and 2007, there were 62,962 and 83,655 Stock Performance Units
granted. The total value of performance-based shares vested and cash units paid was $1.8 million for the first quarter of 2008, compared to $2.2 million for the same period in 2007.

The compensation cost that the Company will ultimately recognize as a result of these awards is dependent on the Companys financial performance and
(for cash units) the price of the Companys stock on the vesting dates. Assuming that the maximum target is achieved for each performance goal, and valuing cash units at the price of StanCorp stock on March 31, 2008, $7.6 million in
additional compensation cost would be recognized through 2010. The target or expected payout is 70% of the total or approximately $5.3 million. This cost is expected to be recognized over a weighted-average period of 1.9 years.

Retention-based Restricted Stock

Awards of retention-based restricted stock to certain senior officers are made less frequently and at irregular intervals by the organization and compensation committee of the board of directors. Participants vest with respect to the stock
after completion of a specified period of employment, generally three or four years. The compensation cost of these awards is measured using the fair market value of the stock at the grant date and is amortized over the specified period of
employment. There was $0.1 million of total unrecognized compensation cost related to unvested retention-based shares at March 31, 2008, which will be recognized by the end of 2008.

A summary of the retention-based restricted stock activity and its characteristics are presented below:

Stock Retainer Fees to Directors

Prior to May 7, 2007, the Company used StanCorp common stock pursuant to the 1999 Omnibus Stock Incentive Plan and the 2002 Stock Incentive Plan to pay a portion of the retainer fees to members of the
Companys board of directors each quarter. Total retainer fees were fixed in dollars. Directors received one-third of the retainer fees in stock and received the remainder in cash. The number of shares issued varied according to the market
value of the stock on the date of the issue. The shares were fully vested when issued. There were 989 shares issued in the first quarter of 2007 as compensation for directors retainer fees.

On November 6, 2006, the board of directors of StanCorp approved a new director compensation schedule that became effective May 7, 2007. Under
the new schedule, each director who is not an employee of StanCorp or Standard receives cash retainer fees that the Company pays quarterly. Additionally, each director will receive 1,000 shares of common stock annually beginning on the day preceding
the annual shareholders meeting in 2008.

Employee Share Purchase Plan

The Companys ESPP allows eligible employees to purchase StanCorp common stock at a 15% discount off the lesser of the fair market value of the stock on either the commencement date of each six-month offering
period or the end-of-the-period purchase date. Under the terms of the plan, each eligible employee may elect to have up to 10% of the employees gross total cash compensation for the period withheld to purchase StanCorp common stock. No
employee may purchase StanCorp common stock having a fair market value in excess of $25,000 in any calendar year. Of the 2.0 million shares authorized for this plan, 0.8 million remain available at March 31, 2008.

The compensation cost for the ESPP was measured as the sum of the value of the 15% discount and the value of the embedded six-month option. The value of
the discount is equal to 15% of the fair market value of the purchase price of the stock. The value of the embedded option is calculated using the Black-Scholes option pricing model using the assumptions noted in the following table. Expected stock
price volatility was based on the volatility of StanCorp common stock over the six months preceding the offering period. The risk-free rate was based on the U.S. Treasury yield curve in effect at the time of the grant.

The weighted-average per-share fair value for the Companys ESPP offerings was $11.70 for the
first quarter of 2008, compared to $10.19 for the first quarter of 2007. The Companys compensation cost resulting from the ESPP was $0.5 million and $0.4 million for the first quarters of 2008 and 2007, respectively. The related tax benefit
was $0.2 million and $0.1 million for the same periods, respectively.

|5. | RETIREMENT BENEFITS
|-- | -------------------

The Company has two
non-contributory defined benefit pension plans: the employee pension plan and the agent pension plan. The employee pension plan is for all eligible employees of StanCorp and its subsidiaries and was frozen effective January 2003 for new
participants. The agent pension plan, which is frozen for new participants, is for former field employees and agents. Both plans are sponsored and administered by Standard. The defined benefit pension plans provide benefits based on years of service
and final average pay.

In addition, Standard sponsors and administers a postretirement benefit plan that includes medical, prescription
drug benefits and group term life insurance. Eligible retirees are required to contribute specified amounts for medical and prescription drug benefits that are determined periodically and are based on retirees length of service and age at
retirement. Effective January 1, 2006, participation in the postretirement benefit plan is limited to employees who had reached the age of 40 as of January 1, 2006, or whose combined age and length of service were equal to or greater than
45 years at January 1, 2006.

The following tables set forth the components of net periodic benefit cost and other amounts recognized
in other comprehensive income (loss) for pension benefits and postretirement benefits:

The Company is not obligated to make any contributions to its pension plans for 2008.

Eligible employees are covered by one of two qualified deferred compensation plans sponsored by Standard and Standard Retirement Services under which
a portion of the employee contribution is matched. Employees not eligible for the employee pension plan are eligible for an additional non-elective employer contribution. Contributions to the plan were $3.0 million and $2.3 million for the first
quarters of 2008 and 2007, respectively.

In addition, eligible executive officers are covered by a non-qualified supplemental retirement
plan. Expenses were $0.5 million and $0.6 million for the first quarters of 2008 and 2007, respectively. Furthermore, a gain of $0.1 million, net of tax, was reported in other comprehensive income for the first quarter of 2008 and $0.4 million was
reported in other liabilities.

##### Table of Contents

Eligible executive officers, directors, agents and group producers may participate in one of several
non-qualified deferred compensation plans under which a portion of the deferred compensation for participating executive officers, agents and group producers is matched. The liability for the plans was $9.1 million and $8.9 million at March 31,
2008, and December 31, 2007, respectively.



|6. | DERIVATIVE FINANCIAL INSTRUMENTS
|-- | --------------------------------

The Company
markets indexed annuities, which permit the holder to elect an interest rate return or an indexed return, where interest credited to the contracts is based on the performance of the S&P 500 index, subject to an upper limit or cap. Policyholders
may elect to rebalance between interest crediting options at renewal dates annually. At each renewal date, the Company has the opportunity to re-price the indexed component by changing the cap, subject to minimum guarantees. Statement of Financial
Accounting Standards (SFAS) No. 133, Accounting for Derivative Instruments and Hedging Activities, requires that the Company estimate the fair value of the index-based interest rate guarantees for the current period and for
all future reset periods until contract maturity. Changes in the fair value of the index-based interest guarantees are recorded as interest credited and represent an estimate of the cost of the options to be purchased in the future to hedge the
guarantees, discounted back to the date of the balance sheet using current market indicators for future interest rates, option costs and actuarial estimates for policyholder lapse behavior. The interest credited to policyholders relating to the
change in the fair value of the index-based interest guarantees was a $6.5 million decrease for the first quarter of 2008, compared to a $0.1 million decrease for the first quarter of 2007. The decrease in the first quarter of 2008 primarily was due
to the decline of the S&P 500 Index during the period.

The Company purchases S&P 500 Index options in conjunction with its sales
of indexed annuities. SFAS No. 133 requires companies to recognize all derivative investments as assets in the balance sheet at fair value. These investments are highly correlated to the portfolio allocation decisions of its policyholders, such
that the Company is economically hedged with respect to index-based interest rate guarantees for the current reset period. However, the Company does not use hedge accounting. The fair value of the Companys derivative instruments of $2.3
million and $6.0 million at March 31, 2008, and December 31, 2007, respectively, is included in fixed maturity securities in the consolidated balance sheets. The change in fair value associated with these investments was a decrease of $4.9
million for the first quarter of 2008, compared to an increase of less than $0.1 million for the first quarter of 2007, and is accounted for in the net investment income section of the income statement. For additional fair value information, see
Note 7Fair Value of Financial Instruments.



|7. | FAIR VALUE OF FINANCIAL INSTRUMENTS
|-- | -----------------------------------

In September
2006, the FASB issued SFAS No. 157, Fair Value Measurements, which is intended to increase consistency and comparability in fair value measurements by defining fair value, establishing a framework for measuring fair value, and expanding
disclosures about fair value measurements. SFAS No. 157 applies to other accounting pronouncements that require or permit fair value measurements. SFAS No. 157 is effective for financial statements issued for fiscal years
beginning after November 15, 2007, and interim periods within those fiscal years. StanCorp adopted the provisions of SFAS No. 157 beginning January 1, 2008.

SFAS No. 157 establishes a three-level hierarchy for disclosure of assets and liabilities recorded at fair value. The classification of assets and
liabilities within the hierarchy is based on whether the inputs to the valuation methodology used for measurement are observable or unobservable. Observable inputs reflect market-derived or market-based information obtained from independent sources
while unobservable inputs reflect our estimates about market data.

The fair value hierarchy prioritizes the inputs to valuation techniques
used to measure fair value into three broad levels: Level 1 inputs are based upon quoted prices in active markets for identical assets or liabilities that we can access at the measurement date. Level 2 inputs are based upon quoted prices for similar
instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based

valuation techniques for which all significant assumptions are observable in the market. Level 3 inputs are generated from model-based techniques that use
significant assumptions not observable in the market. These unobservable assumptions reflect the Companys estimates of assumptions that market participants would use in pricing the asset or liability.

Fixed maturity securitiesavailable-for-sale, S&P 500 index options and index-based interest guarantees are recorded at fair value on a
recurring basis. The Company currently has no assets or liabilities measured at fair value on a nonrecurring basis. In the Companys consolidated statements of income and comprehensive income, unrealized gains and losses are reported in other
comprehensive income for fixed maturity securitiesavailable-for-sale, in net investment income for S&P 500 index options and in interest credited for index-based interest guarantees.

There are three types of valuation techniques described in SFAS No. 157: (1) the market approach, which uses prices or other relevant
information generated by market transactions involving identical or comparable assets or liabilities; (2) the income approach, which uses the present value of cash flows or earnings; and (3) the cost approach, which uses replacement costs
more readily adaptable for valuing physical assets.

Fixed maturity securitiesavailable-for-sale are placed into two groups depending
on the valuation technique used to determine the fair value of the securities. Fixed maturity securities totaling $5.15 billion, or approximately 99%, were valued using the market approach and Level 1 measurement based on quoted market prices where
available, or on values obtained from independent pricing services. The remaining $49.9 million of fixed maturity securities were valued using the income approach and Level 2 measurement, where the expected future cash flows for the fixed maturity
securities were discounted to present value based on information such as credit quality, market conditions and credit spread, which is the difference between the yields for the fixed maturity securities in relation to comparable U.S. Treasury rates.

The valuation technique used to determine the fair value of S&P 500 index options is the market approach. The monthly valuations for
the Companys S&P 500 index options are provided to us by the investment banks with which we do business. The valuations are an estimate of the mid-market values of the positions, based on proprietary valuation models using information
derived from estimated or actual bids and offers for similar positions.

The valuation technique used to determine the fair value of
index-based interest guarantees is the income approach. The liability is the present value of future cash flows attributable to the projected index growth in excess of cash flows driven by fixed interest rate guarantees for the indexed annuity
product. Level 3 assumptions for policyholder behavior and future index interest rate declaration significantly impact the calculation.

The following table sets forth the estimated fair values of assets and liabilities measured and recorded at fair value on a recurring basis at March 31, 2008:

|8. | DEFERRED ACQUISITION COSTS (DAC), VALUE OF BUSINESS ACQUIRED (VOBA), OTHER INTANGIBLE ASSETS AND GOODWILL
|-- | -------------------------------------------------------------------------------------------------------------

DAC, VOBA, other intangible assets and goodwill are considered intangible assets. These intangible assets are generally originated through the issuance of
new business or the purchase of existing business, either by purchasing blocks of insurance policies from other insurers or by the outright purchase of other companies. The Companys intangible assets are subject to impairment tests on an
annual basis or more frequently if circumstances indicate that carrying values may not be recoverable.

Acquisition costs that the Company
has deferred as DAC are those costs that vary with and primarily are related to the acquisition and, in some instances, the renewal of insurance products. These costs are typically one-time expenses that represent the cost of originating new
business and placing that business in force. Certain costs related to obtaining new business and acquiring business through reinsurance agreements have been deferred and will be amortized to accomplish matching against related future premiums or
gross profits, as appropriate. The Company normally defers certain acquisition-related commissions and incentive payments, certain costs of policy issuance and underwriting, and certain printing costs. Assumptions used in developing DAC and
amortization amounts each period include the amount of business in force, expected future persistency, withdrawals, interest rates and profitability. These assumptions are modified to reflect actual experience when appropriate. Additional
amortization of DAC is charged to current earnings to the extent it is determined that future premiums or gross profits are not adequate to cover the remaining amounts deferred. DAC totaled $212.2 million and $202.3 million at March 31, 2008,
and December 31, 2007, respectively. Changes in actual persistency are reflected in the calculated DAC balance. Costs that do not vary with the production of new business are not deferred as DAC and are charged to expense as incurred.

DAC for group and individual disability insurance products and group life insurance products is amortized over the life of related
policies in proportion to future premiums in accordance with SFAS No. 60, Accounting and Reporting by Insurance Enterprises. Beginning with the adoption of Statement of Position (SOP) 05-1 on January 1, 2007, the
Company began amortizing DAC for group disability and life insurance products over the initial premium rate guarantee period, which averages 2.5 years. DAC for individual disability insurance products is amortized in proportion to future premiums
over the life of the contract, averaging 20 to 25 years with approximately 50% and 75% expected to be amortized by years 10 and 15, respectively.

The Companys individual deferred annuities and group annuity products are classified as investment contracts. DAC related to these products is amortized over the life of related policies in proportion to expected gross profits in
accordance with SFAS No. 97, Accounting and Reporting by Insurance Enterprises for Certain Long-Duration Contracts and for Realized Gains and Losses from the Sale of Investments. For the Companys individual deferred annuities, DAC
is generally amortized over 30 years with approximately 50% and 90%

expected to be amortized by years 5 and 15, respectively. DAC for group annuity products is amortized over 10 years with approximately 30% expected to be
amortized by year five.

VOBA primarily represents the discounted future profits of business assumed through reinsurance agreements. We
have established VOBA for a block of individual disability business assumed from the Minnesota Life Insurance Company (Minnesota Life) and a block of group disability and group life business assumed from Teachers Insurance and Annuity
Association of America (TIAA). VOBA is generally amortized in proportion to future premiums for group and individual disability insurance products and group life products. However, a portion of the VOBA related to the TIAA transaction
associated with an in force block of group long term disability claims for which no ongoing premium is received is amortized in proportion to expected gross profits. If actual premiums or future profitability are inconsistent with our assumptions,
the Company could be required to make adjustments to VOBA and related amortization. For the VOBA associated with the Minnesota Life block of business reinsured, the amortization period is up to 30 years and is amortized in proportion to future
premiums. The amortization period of the intangible asset for the marketing agreement with Minnesota Life is up to 25 years. The VOBA associated with the TIAA transaction is comprised of two parts with differing amortization methods. The
amortization period was up to 10 years for VOBA that was amortized in proportion to premiums and up to 20 years for VOBA that is amortized in proportion to expected gross profits. VOBA totaled $33.4 million and $34.4 million at March 31, 2008,
and December 31, 2007, respectively. Upon adoption of SOP 05-1, the premium portion of the VOBA related to TIAA was recorded as a $10.0 million reduction to retained earnings.

VOBA related to the TIAA group long term disability claims, for which no further premiums are due, is amortized in proportion to expected gross profits.
At March 31, 2008, DAC and VOBA balances amortized in proportion to expected gross profits accounted for 29.0% and 26.8%, or $61.5 million and $8.9 million of the total balance for DAC and VOBA, respectively. At December 31, 2007, DAC and
VOBA balances amortized in proportion to expected gross profits accounted for 29.5% and 27.3%, or $59.7 million and $9.4 million of the total balance for DAC and VOBA, respectively.

Key assumptions, which will affect the determination of expected gross profits for determining DAC and VOBA balances, are:



| |  |  | Persistency.
| | - |  | ------------



| |  |  | Investment income.
| | - |  | ------------------



| |  |  | Interest credited.
| | - |  | ------------------



| |  |  | Stock market performance.
| | - |  | -------------------------



| |  |  | Capital gains and losses.
| | - |  | -------------------------



| |  |  | Claim termination rates.
| | - |  | ------------------------

Although a
change in a single assumption may have an impact on the calculated amortization of DAC or VOBA, it is the relationship of that change to the changes in other key assumptions that determines the ultimate impact on DAC or VOBA amortization. Because
actual results and trends related to these assumptions do vary from those assumed, the Company revises these assumptions annually to reflect its current best estimate of expected gross profits. As a result of this process, known as
unlocking, the cumulative balances of DAC and VOBA are adjusted with an offsetting benefit or charge to income to reflect changes in the period of the revision. An unlocking event that results in an after-tax benefit generally occurs as
a result of actual experience or future expectations being favorable compared to previous estimates. An unlocking event that results in an after-tax charge generally occurs as a result of actual experience or future expectations being unfavorable
compared to previous estimates. As a result of unlocking, the amortization schedule for future periods is also adjusted. Due to unlocking, DAC and VOBA balances decreased $0.7 million in the first quarter of 2008 and decreased $0.2 million for the
first quarter of 2007. Based on past experience, future changes in DAC and VOBA balances due

to changes in underlying assumptions are not expected to be material. However, significant, unanticipated changes in key assumptions, which affect the
determination of expected gross profits, may result in a large unlocking event that could have a material adverse effect on the Companys financial position or results of operations.

The Companys other intangible assets are subject to amortization and consist of certain customer lists and a marketing agreement. Customer lists
were acquired primarily in connection with the purchase of Invesmart, Inc. (Invesmart), the purchase of DPA, Inc. and with the acquisition of small investment advisory firms. Customer lists have a combined estimated weighted-average
remaining life of approximately 9.1 years. The marketing agreement accompanied the Minnesota Life transaction and provides access to Minnesota Life agents, some of whom now market Standards individual disability insurance products. The
amortization period for the Minnesota Life marketing agreement is up to 25 years. Other intangible assets totaled $51.5 million and $52.1 million at March 31, 2008, and December 31, 2007, respectively.

Goodwill totaled $36.1 million and $36.0 million at March 31, 2008, and December 31, 2007, respectively, and is related to the purchase of
Invesmart, which is part of the Asset Management segment.

|9. | CONTINGENCIES AND COMMITMENTS
|-- | -----------------------------

In the normal course
of business, the Company is involved in various legal actions and other state and federal proceedings. A number of actions or proceedings were pending at March 31, 2008. In some instances, lawsuits include claims for punitive damages and
similar types of relief in unspecified or substantial amounts, in addition to amounts for alleged contractual liability or other compensatory damages. In the opinion of management, the ultimate liability, if any, arising from the actions or
proceedings is not expected to have a material adverse effect on the Companys business, financial position, results of operations or cash flows.

The Company maintains a $200 million senior unsecured revolving credit facility (Facility), which expires June 15, 2012. At the option of StanCorp and with the consent of the lenders under the
Facility, during May 2008, the expiration date can be extended for an additional one-year period. Additionally, upon the request of StanCorp and with consent of the lenders under the Facility, the Facility can be increased by up to $100 million to a
total of up to $300 million. Borrowings under the Facility will be used to provide for working capital and general corporate purposes of the Company and its subsidiaries and the issuance of letters of credit.

Under the agreement, StanCorp is subject to customary covenants that take into consideration the impact of material transactions, changes to the
business, compliance with legal requirements and financial performance. The two financial covenants are based on the Companys total debt to total capitalization ratio and consolidated net worth. The Facility is subject to performance pricing
based upon the Companys total debt to total capitalization ratio and includes interest based on a Eurodollar margin, plus facility and utilization fees. At March 31, 2008, StanCorp was in compliance with all covenants under the Facility
and had no outstanding balance on the Facility.

On May 29, 2007, the Company completed a public debt offering of $300 million of
6.90%, junior subordinated debentures (Subordinated Debt). The Subordinated Debt has a final maturity on June 1, 2067, is non-callable for the first 10 years and is subject to a replacement capital covenant. The covenant limits
replacement of the Subordinated Debt for the first 40 years to be redeemable only with securities that carry equity-like characteristics that are the same as or more equity-like than the Subordinated Debt. The principal amount of the Subordinated
Debt is payable at final maturity. Interest is payable semi-annually at 6.90% in June and December for the first 10 years and quarterly thereafter at a floating rate of three-month LIBOR plus 2.51%. StanCorp has the option to defer interest payments
for up to five years.



|10. | ACCOUNTING PRONOUNCEMENTS
|--- | -------------------------

In December 2007, the
FASB issued SFAS No. 141 (Revised 2007), Business Combinations. The revised standard will improve, simplify and converge internationally the accounting for business combinations. Under SFAS No. 141R, an acquiring entity in a
business combination must recognize the assets acquired, the liabilities assumed, and any noncontrolling interest in the acquired entity at the acquisition date fair values, with limited exceptions. In addition, SFAS No. 141R requires the
acquirer to disclose all information that investors and other users need to evaluate and understand the nature and financial effect of the business combination. SFAS

##### Table of Contents

No. 141R applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period
beginning on or after December 15, 2008. Earlier adoption is prohibited. Accordingly, the Company will record and disclose business combinations under the revised standard beginning January 1, 2009.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements  An Amendment of ARB
No. 51. The new statement establishes new accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. Specifically, SFAS No. 160 requires the recognition of a
noncontrolling interest (formerly referred to as minority interest) as equity in the consolidated financial statements and separate from the parents equity. The amount of net income attributable to the noncontrolling interest will
be identified and included in consolidated net income on the face of the income statement. SFAS No. 160 clarifies that changes in a parents ownership interest in a subsidiary that do not result in deconsolidation are equity transactions
if the parent retains its controlling financial interest. In addition, this statement requires that a parent recognize a gain or loss in net income when a subsidiary is deconsolidated. This statement also includes expanded disclosure requirements
regarding interests of the parent and its noncontrolling interest. SFAS No. 160 is effective for fiscal years beginning on or after December 15, 2008, and earlier adoption is prohibited. The Company has performed an analysis of the impact
that the adoption of SFAS No. 160 will have on our financial statements, and we do not expect it to have a material effect.

In March
2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activitiesan Amendment of FASB Statement 133. SFAS No. 161 expands the disclosure requirements for derivative instruments and hedging
activities. The enhanced disclosures required by SFAS No. 161 include how and why an entity uses derivative instruments, how derivative instruments and related hedged items are accounted for under SFAS No. 133 and its related
interpretations, and how derivative instruments and related hedged items affect an entitys financial position, financial performance and cash flows. The guidance in SFAS No. 161 is effective for fiscal years and interim periods beginning
after November 15, 2008. The Company plans to adopt the new standard on January 1, 2009.

|------- | -------------------------------------------------------------------------------------

As used in this Form 10-Q, the terms StanCorp, Company, we, us and our refer to StanCorp
Financial Group, Inc. and its subsidiaries, unless the context otherwise requires. The following analysis of the consolidated financial condition and results of operations of StanCorp should be read in conjunction with the unaudited consolidated
financial statements and related condensed notes thereto. See Part 1, Item 1, Financial Statements.

Our filings with
the Securities and Exchange Commission (SEC) include our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, proxy statements, registration statements and amendments to those reports. Access to all
filed reports is available free of charge on our website at www.stancorpfinancial.com/investors as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. The SEC also maintains an Internet
site that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC at www.sec.gov.

The following management assessment of the financial condition and results of operations should be read in conjunction with the consolidated financial statements and notes thereto in our 2007 Form 10-K. Those
consolidated financial statements and certain disclosures made in this Form 10-Q have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and require us to make estimates and
assumptions that affect reported amounts of assets and liabilities and contingent assets and contingent liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during each reporting period. The
estimates most susceptible to material changes due to significant judgment are identified as critical accounting policies. The results of these estimates are critical because they affect our profitability and may affect key indicators used to
measure the Companys performance. See Critical Accounting Policies and Estimates.

We have made certain statements, which
are predictive in nature and not based on historical facts, in this Form 10-Q, and from time to time in our public filings, news releases and oral presentations and discussions. These statements are forward-looking and, accordingly,
involve risks and uncertainties that could cause actual results to differ materially from those discussed or implied. Although such forward-looking statements have been made in good faith and are based on reasonable assumptions, there is no
assurance that the expected results will be achieved. See Forward-looking Statements.

Executive Summary

Financial Results Overview

Net
income per diluted share was $1.02 for the first quarter of 2008, compared to $0.90 for the first quarter of 2007. Net income for these same periods was $50.3 million and $48.3 million, respectively. Results for the first quarter reflected premium
growth, comparatively favorable claims experience for the group insurance businesses and a 4.6 million reduction in diluted weighted-average shares outstanding primarily due to share repurchases. These factors were partially offset by the
decrease in income before income taxes in the Asset Management segment. The results in the Asset Management segment reflected the impact of declining equity markets on revenues and the amortization of deferred acquisition costs in the retirement
plans business.

Outlook

For 2008, we will continue to focus on our long-term objectives and address challenges that may arise with financial discipline and from a position of superior financial strength. We manage for profitability, focusing on good business
diversification, disciplined product pricing, sound underwriting, effective claims management and high quality customer service.

##### Table of Contents

For 2008, the Company has established the following expectations:



| |  |  | Premium growth in the range of 6% to 8%, a rate we expect will maintain our historical pattern of growing at least 1% to 2% more than what we estimate the industry
growth rate will be.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An annual benefit ratio in the range of 77.5% to 79.5% for the group insurance business, noting that our average actual experience over the last four years has been
toward the lower end of this range. Claims experience can fluctuate widely from quarter to quarter.

Premium growth in our Insurance Services segment and administrative fee growth in our Asset
Management segment are the primary drivers in consolidated growth. Premiums for the Insurance Services segment increased 9.1% to $534.3 million for the first quarter of 2008 compared to the same period in 2007. The increase in premiums was primarily
due to growth in both the group and individual insurance businesses. Group insurance premium growth was driven by some large case sales in the second half of 2007. These 2007 sales continue to benefit premium growth in the first quarter of 2008. In
addition, premiums for the individual disability business included $3.7 million received related to the termination of reinsurance on a small block of reinsured policies and claims. See Business Segments-Insurance Services Segment.
Administrative fees for our Asset Management segment increased 5.1% to $28.8 million for the first quarter of 2008 compared to the same period in 2007. Administrative fee growth in our Asset Management segment was due to retirement plan business
growth through the acquisition of DPA, Inc. in the third quarter of 2007, which added approximately $1.3 million in administrative fees. Administrative fee growth was also due to increased fees from commercial mortgage loan servicing related to
increased commercial mortgage loan sales in the fourth quarter of 2007.

Net Investment Income

Net investment income increased 4.5% to $128.8 million for the first quarter of 2008 compared to the first quarter of 2007. Net investment income
primarily is affected by changes in levels of invested assets, interest rates, the change in fair value of derivative assets and commercial mortgage loan prepayment fees.

##### Table of Contents

The increase in net investment income for the first quarter of 2008 compared to the same period in 2007
primarily was due to an increase of 7.3% to $8.91 billion in average invested assets, which primarily was the result of the investment of additional cash from operations. Average invested assets do not include cash and cash equivalents. The increase
in net investment income was partially offset by a decrease in the fair value of derivative assets, lower portfolio yields of fixed maturity securities and commercial mortgage loans and a decrease in commercial mortgage loan prepayment fees. The
fair value adjustment to derivative assets was a decrease of $4.9 million for the first quarter of 2008, compared to an increase of less than $0.1 million for the first quarter of 2007. The portfolio yields for our fixed maturity securities and
commercial mortgage loan portfolios decreased to 5.54% and 6.36% respectively, for the first quarter of 2008, compared to 5.57% and 6.39% respectively, for the first quarter of 2007. Commercial mortgage loan prepayment fees were $1.8 million for the
first quarter of 2008, compared to $2.0 million for the first quarter of 2007.

Net Capital Gains (Losses)

Net capital gains and losses are reported in Other. Net capital losses were $4.4 million before tax for the first quarter of 2008, compared to
net capital gains of $0.9 million before tax for the first quarter of 2007. Net capital gains and losses occur as a result of sale or impairment of the Companys assets, neither of which is likely to occur in regular patterns. The net capital
losses in the first quarter of 2008 were primarily the result of losses on disposal of fixed maturity securities during the quarter.

Benefits and Expenses

Benefits to Policyholders

Benefits to policyholders, including interest credited, for the Insurance Services segment increased 6.7% to $407.1 million for the first quarter of 2008
compared to the same period in 2007. The increase primarily was due to business growth as evidenced by premium growth, offset by comparatively favorable claims experience in our group insurance business.

Benefits to policyholders, including interest credited, for the Asset Management segment decreased 1.1% to $25.8 million for the first quarter of 2008
compared to the same period in 2007. This was due to decreased interest credited, which resulted primarily from the decline of the S&P 500 Index. The decrease in interest credited was offset by growth in individual fixed annuity deposits. The
growth in average assets under administration for the retirement plans general account and individual fixed annuities was 11.2% and 11.3%, respectively, for the first quarter of 2008 compared to the same period in 2007.

Operating Expenses

Operating
expenses increased 10.0% to $116.9 million for the first quarter of 2008 compared to the same period of 2007. The increase included operating expense growth due to business growth as evidenced by premium growth and technology infrastructure costs
related to the integration of group annuity and trust product platforms used to administer our retirement plans business. 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
increased 14.4% to $57.2 million for the first quarter of 2008 compared to the same period in 2007. The increase primarily was due to premium growth and individual annuity sales in the first quarter of 2008.

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 acquired through the purchase of Invesmart, Inc. (Invesmart), DPA, Inc. and several small investment advisory firms. The customer lists are amortized over 10 years. The
amortization for the marketing agreement with the Minnesota Life Insurance Company (Minnesota Life) is up to 25 years. The net deferral for DAC, VOBA and intangibles for the first quarter of 2008 increased $0.6 million compared to the
same period of 2007. In addition, a cumulative effect adjustment of $39.4 million after-tax was recorded as a reduction to retained earnings as of January 1, 2007, as a result of the adoption of Statement of Position (SOP) 05-1,
Accounting by Insurance Enterprises for Deferred Acquisition Costs in Connection With Modifications or Exchanges of Insurance Contracts. See Item 1, Financial StatementsCondensed Notes to Unaudited Consolidated Financial
StatementsNote 8Deferred Acquisition Costs (DAC), Value of Business Acquired (VOBA), Other Intangible Assets and Goodwill.

Income Taxes

Total income taxes may differ from the amount computed by applying the federal
corporate tax rate of 35% because of the net result of permanent differences and the inclusion of state and local income taxes, net of the federal benefit. The combined federal and state effective income tax rates were 33.9% and 34.6% for the first
quarters of 2008 and 2007, respectively. At March 31, 2008, the years open for audit by the Internal Revenue Service (IRS) are 2004 through 2007. The federal statute of limitations for the 2004 tax year expires in September 2008.

Business Segments

StanCorp operates
through two reportable segments: Insurance Services and Asset Management, as well as an Other category for activity outside of the two segments. 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, and individual fixed annuities. Effective January 1, 2007, the administration and servicing operations for the retirement plans group annuity
contracts and the trust products began operating under the name Standard Retirement Services, Inc.

Segment revenues measured as a
percentage of total revenues, excluding net capital losses, were 88.9% for the Insurance Services segment and 10.7% for the Asset Management segment for the first quarter of 2008. Segment revenues measured as a percentage of total revenues,
excluding net capital gains, for the first quarter of 2007 were 89.0% for Insurance Services and 11.0% for Asset Management.

Net capital
gains and losses on investments, return on capital not allocated to the product segments, holding company expenses, interest on debt and adjustments made in consolidation are reflected in Other.

Insurance Services Segment

As the Insurance Services segment is our largest segment, it substantially influences our consolidated financial results. Income before income taxes for
the Insurance Services segment was $78.9 million for the first quarter of 2008, compared to $67.1 million for the first quarter of 2007. Results for the comparative periods were affected by premium growth and by comparatively favorable claims
experience in our group insurance business.

Revenues

Revenues for the Insurance Services segment increased 8.4% to $619.5 million for the first quarter of 2008 compared to the same period in 2007. The growth
in revenues for both comparative periods primarily was due to increased premiums and net investment income in our group insurance business.

Premiums

Premiums for the Insurance Services segment increased 9.1% to $534.3 million for the first quarter of 2008
compared to the same period in 2007. 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 $120.8 million and $120.1 million for the first quarters of 2008 and 2007, 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,
which we believe demonstrates our commitment to customer service and pricing discipline for new sales. Persistency is reported annually.

Organic Growth.    A portion of our premium growth in our group insurance in force business is affected by employment and wage rate growth. Organic growth is also affected by changes in price per insured
and the average age of employees. Current economic conditions are not favorable for significant organic growth in our insurance business.

##### Table of Contents

Premium growth was offset by ERRs of $10.1 million for the first quarter of 2008, compared to $11.0
million for the same period in 2007. ERRs, which are refunds to certain group contract holders based on favorable claims experience, can fluctuate widely from quarter to quarter depending on the underlying experience of specific contracts.

In addition to the factors listed above, premiums for the first quarter included $3.7 million received related to the termination of
reinsurance on a small block of reinsured policies and claims. Offsetting the premiums received in this termination of reinsurance were $3.9 million in additional reserves assumed. The termination of these agreements was made primarily for the
purpose of gaining administrative efficiencies.

Net Investment Income

Net investment income for the Insurance Services segment increased 4.1% to $82.9 million for the first quarter of 2008 compared to the same period in
2007. The increases in net investment income primarily were affected by growth in average invested assets due to premium growth. See Consolidated Results of OperationsRevenuesNet Investment Income.

Benefits and Expenses

Benefits to Policyholders (including interest credited)

Three primary factors that affect benefits to policyholders are
reserves that are established in part based on premium level, claims experience and the assumptions used to establish related reserves. The predominant factors affecting claims experience are claims incidence measured by the number of claims, and
claims 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 claims incidence and claims severity, in addition to new-money investment interest
rates and overall portfolio yield, as both affect the discount rate used to establish reserves.

Benefits to policyholders, including
interest credited, for the Insurance Services segment increased 6.7% to $407.1 million for the first quarter of 2008 compared to the same period in 2007. The increase primarily resulted from business growth as evidenced by premium growth, offset by
favorable claims experience. Premiums for the Insurance Services segment increased 9.1% to $534.3 million for the first quarter of 2008 compared to the same period in 2007.

Because premium growth is one of the primary factors that affect benefits to policyholders, the benefit ratio, calculated as benefits to policyholders
and interest credited as a percentage of premiums, is utilized to provide a measurement of claims normalized for premium growth. The benefit ratio for our group insurance product lines for the first quarter of 2008 was 76.6%, compared to 79.6% for
the first quarter of 2007. The benefit ratio for the first quarter of 2008 was below the Companys estimated annual range of 77.5% to 79.5% for 2008 but well within our normal historical range. Claims experience can fluctuate widely from
quarter to quarter.

In 2007, we adopted a new group life waiver table, the Society of Actuaries Table 2005, to be used in the calculation
of reserves for group life waiver claims incurred in 2007 and later. Adoption of this table resulted in a reduction in the amount of reserves established for new group life waiver claims of $15.5 million for the last nine months of 2007 compared to
the reserves that would have been established using the prior table. The effect on first quarter 2008 results was a reduction of $7.3 million in reserves established for new group life waiver claims compared to the reserves that would have been
established using the prior table.

The benefit ratio for our individual disability business was 70.6% for the first quarter of 2008,
compared to 53.5% for the first quarter of 2007, primarily reflecting less favorable claims experience. The first quarter benefits ratio for individual disability included $3.7 million of premium and $3.9 million in additional reserves related to
the termination of reinsurance on a small block of reinsured policies and claims. Excluding the effects

##### Table of Contents

of this termination of reinsurance, the benefit ratio would have been 67.0% for the first quarter of 2008. Due to the size of our individual disability
business, claims experience can fluctuate more widely from quarter to quarter than that of our group insurance business.

Generally, we
expect the individual disability benefit ratio to trend down over the next few years as the Minnesota Life block becomes a smaller portion of the total business, and the corresponding shift in revenues from net investment income to premiums. The
decrease year to year in the expected benefit ratio does not necessarily indicate an increase in profitability; rather it reflects a change in the mix of revenues from the business.

The discount rate used for the first quarter of 2008 for newly established long term disability claim reserves decreased to 5.00% from the fourth quarter
of 2007 discount rate of 5.35% and the first quarter of 2007 discount rate of 5.50%.

If investment rates prove to be lower than provided
for in the margin between the new money investment rate and the reserve discount rate, we could be required to increase reserves, which could cause expense for benefits to policyholders to increase. The margin at March 31, 2008, in our overall
block of business for group insurance between invested asset yield and weighted-average reserve discount rate was 41 basis points. See Liquidity and Capital Resources  Trends in Key Assumptions.

Operating Expenses

Operating
expenses in the Insurance Services segment increased 8.0% to $84.7 million for the first quarter of 2008 compared to the first quarter of 2007. The increase in operating expenses was primarily due to business growth as evidenced by premium growth
and the corresponding set-up and administrative costs on new group business resulting from strong sales in the second half of 2007.

Asset Management Segment

Income before income taxes for the Asset Management segment was $8.3 million for the first
quarter of 2008, compared to $10.4 million for the same period in 2007. The decrease primarily was due to the impact of declining equity markets on revenue, DAC amortization, and planned technology infrastructure costs related to the integration of
our group annuity and trust product administrative platforms. Revenues increased 5.6% for the first quarter of 2008 compared to the same period in 2007.

Revenues

Revenues for the Asset Management segment increased 5.6% to $74.9 million for the first quarter of 2008 compared to the same period in 2007. Revenues from
the retirement plans business include premiums on life contingent annuities, plan and trust administration fees, fees on equity investments held in separate account assets and other assets under administration, and investment income on general
account assets under administration. Most of the sales for this segment are recorded as deposits and are therefore not reflected as premiums. Individual fixed annuity deposits earn investment income, a portion of which is credited to policyholders.

##### Table of Contents

Premiums

Premiums for the Asset Management segment are generated from life-contingent annuities, which primarily are a single-premium product. Premiums and benefits to policyholders reflect both the sale of immediate annuities
by our individual annuity business and the conversion of retirement plan assets into life-contingent annuities, which can be selected by plan participants at the time of retirement. Premiums for the segment can vary significantly from quarter to
quarter due to low sales volume of life-contingent annuities and the varying size of single premiums. Premiums for the Asset Management segment were $6.2 million for the first quarter of 2008, compared to $2.2 million for the first quarter of 2007.

Administrative Fees

Administrative fees for the Asset Management segment were $28.8 million for the first quarter of 2008, compared to $27.4 million for the first quarter of 2007. Administrative fees are earned primarily from assets under administration.

Assets under administration for this segment, including retirement plans, individual fixed annuities and commercial mortgage loans managed
for third party investors, were $21.78 billion and $19.62 billion at March 31, 2008 and 2007, respectively. The increase was primarily due to increased mortgages managed for third party investors and $1.7 billion of assets under
administration added through the third quarter 2007 acquisition of DPA, Inc., a retirement plans business based in Portland, Oregon. These increases in assets under administration were partially offset by market value declines in equity assets under
administration during the first quarter of 2008.

StanCorp Mortgage Investors, LLC (StanCorp Mortgage Investors) originated
$407.3 million and $300.2 million of commercial mortgage loans for the first quarters of 2008 and 2007, respectively. The increases in originations primarily were due to favorable interest rate conditions and distribution channel growth, accompanied
by increased demand for fixed-rate commercial mortgage loans. Commercial mortgage loans managed for other investors increased 38.5% at March 31, 2008, compared with March 31, 2007.

Net Investment Income

Net investment
income for the Asset Management segment was $39.9 million for the first quarter of 2008, compared to $41.3 million for the first quarter of 2007. The decrease primarily was due to a decrease in the fair value of derivative financial instruments in
the first quarter of 2008. The decrease was partially offset by an increase in average retirement plan general account and individual annuity assets under administration. The fair value of derivative instruments decreased $4.9 million for the first
quarter of 2008, compared to an increase in the fair value of less than $0.1 million for the first quarter of 2007. See Item 1, Financial StatementsCondensed Notes to Unaudited Consolidated Financial StatementsNote
6Derivative Financial Instruments. Excluding the effect of changes in the derivative instruments, net investment income increased 8.5% or $3.5 million for the first quarter of 2008 compared to the same period in 2007. Average retirement
plan general account assets under administration increased 8.2% to $1.49 billion for the first quarter of 2008 compared to the same period in 2007. Average individual annuity assets under administration increased 9.7% to $1.36 billion for the first
quarter of 2008 compared to the same period in 2007.

Benefits and Expenses

Benefits to Policyholders

Benefits to
policyholders for the Asset Management segment represents current and future benefits on life-contingent annuities, which vary significantly with life-contingent annuity sales. Benefits to policyholders for the Asset Management segment increased
93.0% to $8.3 million for the first quarter of 2008 compared to the first quarter of 2007. Changes in the level of benefits to policyholders will approximate changes in premium levels because these annuities primarily are single-premium
life-contingent annuity products with a significant portion of all premium payments established as a reserve.

Interest Credited

Interest credited represents interest paid to policyholders on retirement plan general account assets and individual fixed annuity deposits. Interest credited for the Asset Management segment decreased 19.7% to $17.5
million for the first quarter of 2008 compared to the first quarter of 2007. The decrease in interest credited was primarily related to a decline in the S&P 500 index, which is used in valuing the indexed annuities. The decrease for the
comparative periods was partially offset by increased interest credited related to the growth in individual fixed-rate annuity and retirement plan general account assets under administration. See Item 1 Financial StatementsCondensed
Notes to Unaudited Consolidated Financial StatementsNote 6, Derivative Financial Instruments.

Operating Expenses

Operating expenses for the Asset Management segment increased 14.5% to $32.3 million for the first quarter of 2008 compared to the first
quarter of 2007. The increase in operating expenses for this segment was due to a combination of business growth, as evidenced by growth in assets under administration and planned technology infrastructure costs related to the integration of our
group annuity and trust product administrative platforms. In addition, the Company acquired DPA, Inc., a retirement plans business based in Portland, Oregon in the third quarter of 2007. Operating expenses for the first quarter of 2008 include
approximately $0.9 million in expenses related to the operations of this business.

Other

In addition to our two segments, we report our holding company and corporate activity in Other. This category includes net capital gains and
losses, return on capital not allocated to the product segments, holding company expenses, interest on debt and adjustments made in consolidation.

The Other category reported a loss before income taxes of $11.1 million for the first quarter of 2008, compared to a loss before income taxes of $3.7 million for the first quarter of 2007. Contributing to the loss before income taxes for
the first quarter of 2008 was increased interest expense of $5.2 million, primarily related to the $300 million junior subordinated debentures (Subordinated Debt) issuance in May 2007. The interest expense was partially offset by
increased net investment income of $3.6 million for the same comparative periods primarily due to increased levels of invested assets. The increase in invested assets for the first quarter of 2008 is due to the Company retaining more capital at the
holding company level and insurance subsidiaries levels outside of the business segments. See Liquidity and Capital ResourcesFinancing Cash Flows.

Liquidity and Capital Resources

Asset/Liability Matching and Interest Rate Risk Management

Asset/Liability management is a part of our risk management structure. The risks we assume related to asset/liability mismatches
vary with economic conditions. The primary source of economic risk originates from changes in interest rates. It is generally managements objective to align the characteristics of assets and liabilities so that our financial obligations can be
met under a wide variety of economic conditions. From time to time, management may choose to liquidate certain investments and reinvest in different investments so that the certainty of meeting our financial obligations is increased. See
Investing Cash Flows.

We manage interest rate risk, in part, through asset/liability analyses. In keeping with presently
accepted actuarial standards, the Company has made adequate provisions for the anticipated cash flows required to meet contractual obligations and related expenses, through the use of statutory reserves and related items at March 31, 2008.

As a percentage of our fixed maturity investments, callable bonds were 2.8% at March 31, 2008. Since 2001, all of our commercial
mortgage loans originated by us contain a provision requiring the borrower to pay a

prepayment fee to assure that our expected cash flow from commercial mortgage loan investments would be protected in the event of prepayment. Approximately
86% of our commercial mortgage loan portfolio contains this prepayment provision. The remaining commercial mortgage loans contain fixed prepayment fees that mitigate prepayments, but may not fully protect our expected cash flow in the event of
prepayment.

Operating Cash Flows

Net cash provided by operating activities is net income adjusted for non-cash items and accruals. Net cash provided by operating activities was $237.3 million for the first quarter of 2008, compared to $155.7 million
for the first quarter of 2007. The increase in operating cash flows was primarily due to increased deposits from our individual annuity business, and to increased net income.

Investing Cash Flows

We
maintain a diversified investment portfolio primarily consisting of fixed maturity securities and fixed-rate commercial mortgage loans. Investing cash inflows primarily consist of the proceeds of investments sold, matured or repaid. Investing cash
outflows primarily consist of payments for investments acquired or originated.

The insurance laws of the states of domicile and other
states in which the insurance subsidiaries conduct business regulate the investment portfolios of the insurance subsidiaries. Relevant laws and regulations generally limit investments to bonds and other fixed maturity securities, mortgage loans,
common and preferred stock and real estate. Decisions to acquire and dispose of investments are made in accordance with guidelines adopted and modified from time to time by the insurance subsidiaries boards of directors. Each investment
transaction requires the approval of one or more members of senior investment staff, with increasingly higher approval authorities required for transactions that are more significant. Transactions are reported quarterly to the finance and operations
committee of the board of directors for Standard and to the board of directors for The Standard Life Insurance Company of New York.

Net
cash used in investing activities was $358.5 million and $219.2 million for the first quarters of 2008 and 2007, respectively.

Our target
investment portfolio allocation is approximately 60% fixed maturity securities and 40% commercial mortgage loans. At March 31, 2008, our portfolio consisted of 57.3% fixed maturity securities, 41.9% commercial mortgage loans and 0.8% real
estate.

Fixed Maturity Securities

Our fixed maturity securities totaled $5.20 billion at March 31, 2008. We believe that we maintain prudent diversification across industries, issuers and maturities. Our corporate bond industry diversification
targets are based on the Lehman Investment Grade Credit Index, which is reasonably reflective of the mix of issuers broadly available in the market. We also target a specified level of government, agency and municipal securities in our portfolio for
credit quality and additional liquidity. The overall credit quality of our fixed maturity securities investment portfolio was A (Standard & Poors) at March 31, 2008. The percentage of fixed maturity securities below
investment-grade was 4.4% and 4.1% at March 31, 2008 and December 31, 2007, respectively. At March 31, 2008, bonds on our watch list totaled approximately $54.8 million. We did not have any direct exposure to sub-prime or Alt-A
mortgages in our fixed maturity securities portfolio at March 31, 2008. We held investments in debt securities issued by bond and mortgage insurers at March 31, 2008, with $26.8 million in market value and $40.7 million in book value. The
Company has the ability and intends to hold these securities to recovery and will continue to evaluate these holdings, but currently expects the fair values of its investments in debt securities issued by bond insurers to recover as these debt
securities approach their maturity dates. Should the credit quality of our fixed maturity securities decline, there could be a material adverse effect on our business, financial position, results of operations or cash flows.

##### Table of Contents

At March 31, 2008, our fixed maturity securities portfolio had gross unrealized capital gains of
$157.3 million and gross unrealized capital losses of $62.5 million. Unrealized gains and losses primarily result from holding fixed maturity securities with interest rates higher or lower, respectively, than those currently available at the
reporting date.

Commercial Mortgage Loans

StanCorp Mortgage Investors originates and services fixed-rate commercial mortgage loans for the investment portfolios of our insurance subsidiaries and generates additional fee income from the origination and
servicing of commercial mortgage loans participated to institutional investors.

Commercial mortgage loan originations for internal and
external investors were $407.3 million and $300.2 million for the first quarters of 2008 and 2007, respectively. The increased originations in 2008 reflected a less competitive origination market, partially due to decreased competition from
securitized lenders. The level of commercial mortgage loan originations in any year is influenced by market conditions as we respond to changes in interest rates, available spreads and borrower demand.

At March 31, 2008, StanCorp Mortgage Investors serviced $3.81 billion in commercial mortgage loans for subsidiaries of StanCorp and $2.07 billion
for other institutional investors, compared to $3.66 billion serviced for subsidiaries of StanCorp and $1.90 billion for other institutional investors at December 31, 2007.

The average loan to value ratio for the overall portfolio was approximately 57.4% at March 31, 2008, and the average loan size in the portfolio was
approximately $0.8 million at March 31, 2008. We have the contractual ability to pursue personal recourse on most of the loans.

Capitalized commercial mortgage loan servicing rights associated with commercial loans serviced for other institutional investors were $6.0 million and $4.2 million at March 31, 2008 and 2007, respectively.

At March 31, 2008, there were four commercial mortgage loans totaling $1.9 million in our portfolio that were more than sixty days delinquent, of
which two commercial mortgage loans with a total balance of $0.7 million were in the process of foreclosure. We had a net balance of restructured loans of $1.9 million at March 31, 2008, and a commercial mortgage loan loss reserve of $3.6
million. In March 2008, StanCorp Mortgage Investors purchased two loans from a third party lender related to a current borrower. These loans, which had an aggregate obligation to the previous lender of $31.9 million, were purchased at a discounted
price of $25.0 million. At March 31, 2008, we did not have any direct exposure to sub-prime or Alt-A mortgages. The delinquency rate and loss performance of our commercial mortgage loan portfolio was in line with the recent industry averages as
reported by the American Council of Life Insurers. The performance of our commercial mortgage loan portfolio may fluctuate in the future. Should the delinquency rate or loss performance of our commercial mortgage loan portfolio increase, the
increase could have a material adverse effect on our business, financial position, results of operations or cash flows.

At March 31,
2008, our commercial mortgage loan portfolio was collateralized by properties with the following characteristics:



| |  |  | 44.4% retail properties.
| | - |  | ------------------------



| |  |  | 17.3% industrial properties.

Commercial
mortgage loans in California accounted for 29.4% of our commercial mortgage loan portfolio at March 31, 2008. Through this concentration, we are exposed to potential losses from an economic downturn in California as well as to certain
catastrophes, such as earthquakes and fires, which may affect certain areas of the state. We require borrowers to maintain fire insurance coverage to provide reimbursement for any losses due to fire. We diversify our commercial mortgage loan
portfolio within California by both location and type of property in an effort to reduce certain catastrophe and economic exposure. However, diversification may not always eliminate the risk of such losses. Historically, the delinquency rate of our
California-based commercial mortgage loans has been substantially below the industry average and consistent with our experience in other states. In addition, when new loans are underwritten, we do not require earthquake insurance for properties on
which we make commercial mortgage loans, but do consider the potential for earthquake loss based upon seismic surveys and structural information specific to each property. We do not expect a catastrophe or earthquake damage in California to have a
material adverse effect on our business, financial position, results of operations or cash flows. If economic conditions in California decline, we could experience a higher delinquency rate on the portion of our commercial mortgage loan portfolio
located in California, which could have a material adverse effect on our business, financial position, results of operations or cash flows.

Under the laws of certain states, environmental contamination of a property may result in a lien on the property to secure recovery of the costs of cleanup. In some states, such a lien has priority over the lien of an existing mortgage
against such property. As a commercial mortgage lender, we customarily conduct environmental assessments prior to making commercial mortgage loans secured by real estate and before taking title through foreclosure on real estate collateralizing
delinquent commercial mortgage loans held by us. Based on our environmental assessments, we believe that any compliance costs associated with environmental laws and regulations or any remediation of affected properties would not have a material
adverse effect on our business, financial position, results of operations or cash flows. However, we cannot provide assurance that material compliance costs will not be incurred by us.

In the normal course of business, we commit to fund commercial mortgage loans generally up to 90 days in advance. At March 31, 2008, we had
outstanding commitments to fund commercial mortgage loans totaling $344.9 million, with fixed interest rates ranging from 5.625% to 7.125%. These commitments generally have fixed expiration dates. A small percentage of commitments expire due to the
borrowers failure to deliver the requirements of the commitment by the expiration date. In these cases, we will retain the commitment fee and good faith deposit. Alternatively, if we terminate a commitment due to the disapproval of a
commitment requirement, the commitment fee and good faith deposit may be refunded to the borrower, less an administrative fee.

Financing Cash Flows

Financing cash flows primarily consist of policyholder fund deposits and withdrawals,
borrowings and repayments on the line of credit, borrowings and repayments on long-term debt, repurchases of common stock and dividends paid on common stock. Net cash provided by financing activities was $190.0 million and $62.2 million for the
first quarters of 2008 and 2007, respectively. The increase for 2008 primarily resulted from a larger increase in policyholder deposits net of withdrawals in the first quarter of 2008 compared to the first quarter of 2007.

The Company maintains a $200 million senior unsecured revolving credit facility (Facility) which expires June 15, 2012. At the option of
StanCorp and with the consent of the lenders under the Facility, during May 2008 the expiration date can be extended for an additional one-year period. Additionally, upon the request of StanCorp and with consent of the lenders under the Facility,
the Facility can be increased by up to $100 million to a total of up to $300 million. Borrowings under the Facility will be used to provide for working capital and general corporate purposes of the Company and its subsidiaries and the issuance of
letters of credit.

Under the agreement, StanCorp is subject to customary covenants that take into consideration the impact
of material transactions, changes to the business, compliance with legal requirements and financial performance. The two financial covenants are based on our total debt to total capitalization ratio and consolidated net worth. The Facility is
subject to performance pricing based upon our total debt to total capitalization ratio and includes interest based on a Eurodollar margin, plus facility and utilization fees. At March 31, 2008, StanCorp was in compliance with all covenants
under the Facility and had no outstanding balance on the Facility.

StanCorp filed a $1.0 billion shelf registration statement with the
SEC, which became effective on July 23, 2002, and expires on December 1, 2008, registering common stock, preferred stock, debt securities and warrants. On September 25, 2002, we completed an initial public debt offering of $250
million of 6.875%, 10-year senior notes (Senior Notes), pursuant to the shelf registration statement. The principal amount of the Senior Notes is payable at maturity and interest is payable semi-annually in April and October.

On May 29, 2007, the Company completed a public debt offering of $300 million of 6.90%, Subordinated Debt. The Subordinated Debt has a final
maturity on June 1, 2067, is non-callable at par for the first 10 years and is subject to a replacement capital covenant. The covenant limits replacement of the Subordinated Debt for the first 40 years to be redeemable only with securities,
which carry equity-like characteristics that are the same as or more equity-like than the Subordinated Debt. The principal amount of the Subordinated Debt is payable at final maturity. Interest is payable semi-annually at 6.90% in June and December
for the first 10 years and quarterly thereafter at a floating rate equal to three-month LIBOR plus 2.51%. StanCorp has the option to defer interest payments for up to five years.

Upon expiration of the $1.0 billion shelf registration statement in December 2008, the Company, as a well-known seasoned issuer, has the ability to file
an automatic shelf registration statement for subsequent security issuances.

On May 7, 2007, the board of directors authorized a
repurchase program for up to 6.0 million shares of StanCorp common stock, which replaced the Companys prior share repurchase program. We repurchased 0.2 million shares of common stock at a total cost of $10.9 million for the first
quarter of 2008, compared to 0.2 million shares at $9.3 million for the first quarter of 2007. At March 31, 2008, there were 1.2 million shares remaining under the repurchase program.

Capital Management

State insurance departments
require insurance enterprises to maintain minimum levels of capital and surplus. Our insurance subsidiaries target is generally to maintain capital at 300% of the company action level of Risk-Based Capital (RBC) required by
regulators, which is 600% of the authorized control level RBC required by our states of domicile. The insurance subsidiaries held an estimated 303% of the company action level RBC at March 31, 2008. At March 31, 2008, statutory capital,
adjusted to exclude asset valuation reserves, for our regulated insurance subsidiaries totaled $1.19 billion.

The levels of capital in
excess of targeted RBC we generate vary inversely in relation to our levels of premium growth, primarily due to initial reserve requirements, certain regulatory capital requirements based on premiums and certain acquisition costs associated with
policy issuance. At higher levels of premium growth, we generate less capital in excess of targeted RBC. At very high levels of premium growth, we could generate the need for capital infusions. At lower levels of premium growth, we generate more
capital in excess of targeted RBC. At our expected growth rate, we anticipate generating capital in excess of our 300% target of $125 to $150 million in 2008. In part, we seek to maintain amounts sufficient to fund holding company operating
expenses, interest on our debt and our annual dividends to shareholders.

We will continue to maintain our three priorities, in the
following order, for the remaining excess capital:



| |  |  | Fund internal growth.
| | - |  | ---------------------

##### Table of Contents

| |  |  | Fund acquisitions that are consistent with our mission and meet our return objectives.
| | - |  | --------------------------------------------------------------------------------------



| |  |  | Provide a return to shareholders, via share repurchases and dividends.
| | - |  | ----------------------------------------------------------------------

In addition to the excess capital carried on the insurance subsidiaries, our non-insurance subsidiaries also hold capital in excess of regulatory
requirements. Maintaining additional capital provides timing flexibility if we choose to access capital markets to finance growth or acquisition. StanCorp has a $1.0 billion shelf registration statement with the SEC. Under the shelf registration, we
have issued $550 million in long-term debt. See Liquidity and Capital ResourcesFinancing Cash Flows.

We had debt to
total capitalization ratios of 28.0% and 16.1% at March 31, 2008 and 2007, respectively. The increase in our debt to total capitalization ratio primarily was due to the $300 million Subordinated Debt issuance in May 2007. Certain rating
agencies recognize a portion of the Subordinated Debt as equity. Standard & Poors currently recognizes the Subordinated Debt as 100% equity, while Moodys and AM Best currently recognize 75% of the Subordinated Debt as equity.
Debt to total capitalization after the 75% equity credit was 16.9% at March 31, 2008. StanCorps ratio of earnings to fixed charges, including interest credited to policyholders, was 3.3x and 3.3x for the first quarters of 2008 and 2007,
respectively.

Dividends from Insurance Subsidiary

StanCorps ability to pay dividends to its shareholders, repurchase its shares and meet its obligations substantially depends upon the receipt of
distributions from its subsidiaries, including Standard. Standards ability to pay dividends to StanCorp is affected by factors deemed relevant by Standards board of directors. One factor considered by the board is the ability to maintain
adequate RBC according to Oregon statute. Under Oregon law, Standard may pay dividends only from the earned surplus arising from its business. If the proposed dividend exceeds certain statutory limitations, Standard must receive the prior approval
of the Director of the Oregon Department of Consumer and Business ServicesInsurance Division (Oregon Insurance Division). The current statutory limitations are the greater of (a) 10% of Standards combined capital and
surplus as of December 31 of the preceding year, or (b) the net gain from operations after dividends to policyholders and federal income taxes before realized capital gains or losses for the 12-month period ended on the preceding
December 31. In each case, the limitation must be determined under statutory accounting practices. Oregon law gives the Oregon Insurance Division broad discretion to decline requests for dividends in excess of these limits. There are no
regulatory restrictions on dividends from non-insurance subsidiaries to StanCorp.

In March 2007, Standard paid a dividend of $95 million
to StanCorp. There were no dividends to StanCorp in the first quarter of 2008.

Dividends to Shareholders

The declaration and payment of dividends is subject to the discretion of StanCorps board of directors. It is anticipated that annual dividends will
be paid in December of each year depending on StanCorps financial condition, results of operations, cash requirements, future prospects, regulatory restrictions on distributions from the insurance subsidiaries, the ability of the insurance
subsidiaries to maintain adequate capital and other factors deemed relevant by the board of directors. In addition, the declaration and payment of dividends would be restricted if StanCorp elects to defer interest payments on its subordinated debt.
If elected, the restriction would be in place during the deferral period, which cannot exceed five years. In the fourth quarter of 2007, StanCorp paid an annual cash dividend of $0.72 per share, totaling $35.7 million. StanCorp has paid dividends
each year since its initial public offering in 1999.

Share Repurchases

From time to time, the board of directors has authorized share repurchase programs. Share repurchases are to be effected in the open market or in
negotiated transactions in compliance with the safe harbor provisions of



36



---

##### Table of Contents

Rule 10b-18 under regulations of the Securities Exchange Act of 1934 (the Exchange Act). Execution of the share repurchase program is based upon
managements assessment of market conditions for its common stock and other potential growth opportunities.

On May 7, 2007, the
board of directors authorized a share repurchase program of up to 6.0 million shares of StanCorp common stock. The share repurchase program will be effected in the open market or in negotiated transactions through December 31, 2008. The
share repurchase program replaced our previous share repurchase program, which had 1.2 million shares remaining that expired upon authorization of the new program.

During the first quarter of 2008, we repurchased 0.2 million shares of common stock at a total cost of $10.9 million for a volume weighted-average price of $47.30 per share. At March 31, 2008, there
were 1.2 million shares remaining under the share repurchase program. In addition, during the first quarter of 2008, we acquired 4,065 shares of common stock from executive officers to cover tax liabilities of these officers resulting from the
release of performance-based shares at a total cost of $0.2 million for a volume weighted-average price of $50.78 per common share, which reflects the market price on the transaction date. See Part II, Item 2, Unregistered Sales of Equity
Securities and Use of Proceeds.

Financial Strength Ratings

Financial strength ratings, which gauge claims paying ability, are an important factor in establishing the competitive position of insurance companies. Ratings are important in maintaining public confidence in our
company and in our ability to market our products. Rating organizations continually review the financial performance and condition of insurance companies, including ours. In addition, credit ratings on our Senior Notes and Subordinated Debt are tied
to our financial strength ratings. A ratings downgrade could increase surrender levels for our annuity products, could adversely affect our ability to market our products and could increase costs of future debt issuances. Standard &
Poors, Moodys Investors Service, Inc. and A.M. Best Company provide financial strength and credit ratings.

Standards
financial strength ratings as of May 2008 were:



| |  |  | AA- (Very Strong) by Standard & Poors4th of 20 ratings.
| | - |  | ---------------------------------------------------------



| |  |  | A1 (Good) by Moodys5th of 21 ratings.
| | - |  | ---------------------------------------



| |  |  | A (Excellent) by A.M. Best3rd of 13 ratings.
| | - |  | ---------------------------------------------

Credit Ratings

Standard & Poors, Moodys Investors Service, Inc. and A.M. Best Company provide credit
ratings on StanCorps Senior Notes. As of May 2008, ratings from these agencies were A-, Baa1 and bbb+, respectively. As of May 2008, A.M. Best Company affirmed an issuer credit rating of a+ to Standard.

Standard & Poors, Moodys Investor Services, Inc. and A.M. Best Company also provide credit ratings on StanCorps Subordinated
Debt. As of May 2008, ratings from these agencies were BBB, Baa2 and bbb-, respectively.

Insolvency Assessments

Insolvency regulations exist in many of the jurisdictions in which our subsidiaries do business. Such regulations may require insurance companies operating within the jurisdiction to participate in guaranty
associations. The associations levy assessments against their members for the purpose of paying benefits due to policyholders of impaired or insolvent insurance companies. Association assessments levied against us from January 1, 2006, through
March 31, 2008, aggregated $0.4 million. At March 31, 2008, we maintained a reserve of $0.6 million for future assessments with respect to currently impaired, insolvent or failed insurers.

Statutory Financial Accounting

Standard and The
Standard Life Insurance Company of New York prepare their statutory financial statements in accordance with accounting practices prescribed or permitted by their states of domicile. Prescribed statutory accounting practices include state laws,
regulations and general administrative rules, as well as the Statements of Statutory Accounting Principles set forth in publications of the National Association of Insurance Commissioners.

Statutory net gains from insurance operations before federal income taxes were $76.5 million for the first quarter of 2008, compared to $57.3 million for
the first quarter of 2007. Statutory net gains from operations increased for the first quarter of 2008 compared to the first quarter of 2007 primarily due to a comparatively favorable benefit ratio.

Differences between Statutory and GAAP results for the first quarter of 2008 compared to the first quarter 2007 were due to a decrease in earnings from
non-insurance subsidiaries and a decrease in capital gains that are deferred on a statutory basis. Statutory capital adjusted to exclude asset valuation reserves for our insurance subsidiaries totaled $1.19 billion and $1.01 billion at
March 31, 2008 and 2007, respectively. The asset valuation reserve was $104.5 million and $98.8 million at March 31, 2008 and 2007, respectively.

See Item 1, Financial StatementsCondensed Notes to Unaudited Consolidated
Financial StatementsNote 7, Fair Value of Financial Instruments.

Critical Accounting Policies and Estimates

Our consolidated financial statements and certain disclosures made in this Form 10-Q have been prepared in accordance with GAAP and require us to make
estimates and assumptions that affect reported amounts of assets and liabilities and contingent assets and contingent liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting
periods. The estimates most susceptible to material changes due to significant judgment (identified as the critical accounting policies) are those used in determining asset impairments, DAC, VOBA, other intangibles and goodwill, the
reserves for future policy benefits and claims, and the provision for income taxes. The results of these estimates are critical because they affect our profitability and may affect key indicators used to measure the Companys performance. These
estimates have a material effect on our results of operations and financial condition.

Deferred Acquisition Costs (DAC),
Value of Business Acquired (VOBA), Other Intangible Assets and Goodwill

DAC, VOBA, other intangible assets and goodwill
are considered intangible assets. These intangible assets are generally originated through the issuance of new business or the purchase of existing business, either by purchasing blocks of insurance policies from other insurers or by the outright
purchase of other companies. Our intangible assets are subject to impairment tests on an annual basis or more frequently if circumstances indicate that carrying values may not be recoverable.

##### Table of Contents

Acquisition costs that we have deferred as DAC are those costs that vary with and primarily are related
to the acquisition and, in some instances, the renewal of insurance products. These costs are typically one-time expenses that represent the cost of originating new business and placing that business in force. Certain costs related to obtaining new
business and acquiring business through reinsurance agreements have been deferred and will be amortized to accomplish matching against related future premiums or gross profits, as appropriate. We normally defer certain acquisition-related
commissions and incentive payments, certain costs of policy issuance and underwriting, and certain printing costs. Assumptions used in developing DAC and amortization amounts each period include the amount of business in force, expected future
persistency, withdrawals, interest rates and profitability. These assumptions are modified to reflect actual experience when appropriate. Additional amortization of DAC is charged to current earnings to the extent it is determined that future
premiums or gross profits are not adequate to cover the remaining amounts deferred. DAC totaled $212.2 million and $202.3 million at March 31, 2008, and December 31, 2007, respectively. Changes in actual persistency are reflected in the
calculated DAC balance. Costs that do not vary with the production of new business are not deferred as DAC and are charged to expense as incurred.

DAC for group and individual disability insurance products and group life insurance products is amortized over the life of related policies in proportion to future premiums in accordance with Statement of Financial Accounting Standards
(SFAS) No. 60, Accounting and Reporting by Insurance Enterprises. Beginning with the adoption of SOP 05-1 on January 1, 2007, we began amortizing DAC for group disability and life insurance products over the initial
premium rate guarantee period, which averages 2.5 years. DAC for individual disability insurance products is amortized in proportion to future premiums over the life of the contract, averaging 20 to 25 years with approximately 50% and 75% expected
to be amortized by years 10 and 15, respectively.

Our individual deferred annuities and group annuity products are classified as
investment contracts. DAC related to these products is amortized over the life of related policies in proportion to expected gross profits in accordance with SFAS No. 97, Accounting and Reporting by Insurance Enterprises for Certain
Long-Duration Contracts and for Realized Gains and Losses from the Sale of Investments. For our individual deferred annuities, DAC is generally amortized over 30 years with approximately 50% and 90% expected to be amortized by years 5 and 15,
respectively. DAC for group annuity products is amortized over 10 years with approximately 30% expected to be amortized by year five.

VOBA
primarily represents the discounted future profits of business assumed through reinsurance agreements. We have established VOBA for a block of individual disability business assumed from the Minnesota Life and a block of group disability and group
life business assumed from Teachers Insurance and Annuity Association of America (TIAA). VOBA is generally amortized in proportion to future premiums for group and individual disability insurance products and group life products.
However, a portion of the VOBA related to the TIAA transaction associated with an in force block of group long term disability claims for which no ongoing premium is received is amortized in proportion to expected gross profits. If actual premiums
or future profitability are inconsistent with our assumptions, we could be required to make adjustments to VOBA and related amortization. For the VOBA associated with the Minnesota Life block of business reinsured, the amortization period is up to
30 years and is amortized in proportion to future premiums. The amortization period of the intangible asset for the marketing agreement with Minnesota Life is up to 25 years. The VOBA associated with the TIAA transaction is comprised of two parts
with differing amortization methods. The amortization periods are up to 10 years for VOBA that is amortized in proportion to premiums and up to 20 years for VOBA that is amortized in proportion to expected gross profits. VOBA totaled $33.4 million
and $34.4 million at March 31, 2008, and December 31, 2007, respectively. Upon adoption of SOP 05-1, the premium portion of the VOBA related to TIAA was recorded as a $10.0 million reduction to retained earnings.

VOBA related to the TIAA group long term disability claims, for which no further premiums are due, is amortized in proportion to expected gross profits.
At March 31, 2008, DAC and VOBA balances amortized in proportion to expected gross profits accounted for 29.0% and 26.8%, or $61.5 million and $8.9 million of the total balance for DAC and VOBA, respectively. At December 31, 2007, DAC and
VOBA balances amortized in



39



---

##### Table of Contents

proportion to expected gross profits accounted for 29.5% and 27.3%, or $59.7 million and $9.4 million of the total balance for DAC and VOBA, respectively.

Key assumptions, which will affect the determination of expected gross profits for determining DAC and VOBA balances, are:



| |  |  | Persistency.
| | - |  | ------------



| |  |  | Investment income.
| | - |  | ------------------



| |  |  | Interest credited.
| | - |  | ------------------



| |  |  | Stock market performance.
| | - |  | -------------------------



| |  |  | Capital gains and losses.
| | - |  | -------------------------



| |  |  | Claim termination rates.
| | - |  | ------------------------

Although a
change in a single assumption may have an impact on the calculated amortization of DAC or VOBA, it is the relationship of that change to the changes in other key assumptions that determines the ultimate impact on DAC or VOBA amortization. Because
actual results and trends related to these assumptions do vary from those assumed, we revise these assumptions annually to reflect the Companys current best estimate of expected gross profits. As a result of this process, known as
unlocking, the cumulative balances of DAC and VOBA are adjusted with an offsetting benefit or charge to income to reflect changes in the period of the revision. An unlocking event that results in an after-tax benefit generally occurs as
a result of actual experience or future expectations being favorable compared to previous estimates. An unlocking event that results in an after-tax charge generally occurs as a result of actual experience or future expectations being unfavorable
compared to previous estimates. As a result of unlocking, the amortization schedule for future periods is also adjusted. Due to unlocking, DAC and VOBA balances decreased $0.7 million in the first quarter of 2008 and decreased $0.2 million for the
first quarter of 2007. Based on past experience, future changes in DAC and VOBA balances due to changes in underlying assumptions are not expected to be material. However, significant, unanticipated changes in key assumptions, which affect the
determination of expected gross profits, may result in a large unlocking event that could have a material adverse effect on the Companys financial position or results of operations.

Our other intangible assets are subject to amortization and consist of certain customer lists and a marketing agreement. Customer lists were acquired
primarily in connection with the purchase of Invesmart, the purchase of DPA, Inc. and with the acquisition of small investment advisory firms. Customer lists have a combined estimated weighted-average remaining life of approximately 9.1 years. The
marketing agreement accompanied the Minnesota Life transaction and provides access to Minnesota Life agents, some of whom now market Standards individual disability insurance products. The amortization period for the Minnesota Life marketing
agreement is up to 25 years. Other intangible assets totaled $51.5 million and $52.1 million at March 31, 2008, and December 31, 2007, respectively.

Goodwill totaled $36.1 million and $36.0 million at March 31, 2008, and December 31, 2007, respectively, and is related to the purchase of Invesmart, which is part of the Asset Management segment.

Reserves

Reserves represent amounts to pay future benefits and claims. Developing the estimates for reserves (and therefore the resulting impact on earnings) requires varying degrees of subjectivity and judgment, depending upon the nature of the
reserve. For most of our reserves, the calculation methodology is prescribed by various accounting and actuarial standards, although judgment is required in the determination of assumptions to use in the calculation. At March 31, 2008, these
reserves represented approximately 88% of total reserves held or $4.55 billion. We also hold reserves that lack a prescribed methodology but instead are determined by a formula that



40



---

##### Table of Contents

we have developed based on our own experience. Because this type of reserve requires a higher level of subjective judgment, we closely monitor its adequacy.
These reserves, which are primarily incurred but not reported reserves associated with our disability products represented approximately 12% of total reserves held at March 31, 2008, or $645.0 million. Finally, a small amount of reserves is
held based entirely upon subjective judgment. These reserves are generally set up as a result of unique circumstances that are not expected to continue far into the future and are released according to pre-established conditions and timelines. These
reserves represented less than 1% of total reserves held at March 31, 2008, or $7.4 million.

Reserves include policy reserves for
claims not yet incurred, and claim reserves for liabilities for unpaid claims and claim adjustment expenses for claims that have been incurred or are estimated to have been incurred but not yet reported to us. These reserves totaled $5.05 billion at
March 31, 2008, and represented over 97% of total reserves, compared to $5.02 billion at December 31, 2007.

Policy Reserves

Policy reserves totaled $913.8 million and $908.3 million at March 31, 2008, and December 31, 2007, respectively. Policy
reserves include reserves established for individual life and individual disability businesses.

Policy reserves for our individual
disability block of business are established at the time of policy issuance using the net level premium method as prescribed by GAAP and represent the current value of projected future benefits including expenses less projected future premium. These
reserves, related specifically to our individual disability block of business, totaled $166.8 million and $164.4 million at March 31, 2008, and December 31, 2007, respectively.

We continue to maintain a policy reserve for as long as a policy is in force, even after a separate claim reserve is established.

Assumptions used to calculate individual disability policy reserves may vary by the age, gender and occupation class of the claimant, the year of policy
issue and specific contract provisions and limitations.

Individual disability policy reserves are sensitive to assumptions and
considerations regarding:



| |  |  | Claim incidence rates.
| | - |  | ----------------------



| |  |  | Claim termination rates.
| | - |  | ------------------------



| |  |  | Discount rates used to value expected future claim payments and premiums.
| | - |  | -------------------------------------------------------------------------



| |  |  | Persistency rates.
| | - |  | ------------------



| |  |  | The amount of monthly benefit paid to the insured less reinsurance recoveries and other offsets.
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | Expense rates including inflation.
| | - |  | ----------------------------------

Policy reserves for our individual and group immediate annuity blocks of business totaled $145.5 million and $141.8 million at March 31, 2008, and December 31, 2007, respectively. These reserves are established at the time of
policy issue and represent the present value of future payments due under the annuity contracts. The contracts are single premium contracts, and, therefore, there is no projected future premium.

Assumptions used to calculate immediate annuity policy reserves may vary by the age and gender of the annuitant and year of policy issue.

Immediate annuity policy reserves are sensitive to assumptions and considerations regarding:



| |  |  | Annuitant mortality rates.
| | - |  | --------------------------



| |  |  | Discount rates used to value expected future annuity payments.
| | - |  | --------------------------------------------------------------

##### Table of Contents

Policy reserves for our individual life block of business totaled $601.5 million and $602.1 million at
March 31, 2008, and December 31, 2007, respectively. Effective January 1, 2001, substantially all of our individual life policies and the associated reserves were ceded to Protective Life Insurance Company under a reinsurance
agreement.

Policy reserves are calculated using our best estimates of assumptions and considerations at the time the policy was issued,
adjusted to allow for the effect of adverse deviations in actual experience. These assumptions are not subsequently modified unless policy reserves become inadequate, at which time, we may need to change assumptions to increase reserves.

Claim Reserves

Claim reserves are
established when a claim is incurred or is estimated to have been incurred but not yet reported to us and, as prescribed by GAAP, equals our best estimate of the present value of the liability of future unpaid claims and claim adjustment expenses.
Reserves for incurred but not reported (IBNR) claims are determined using company experience and consider actual historical incidence rates, claim reporting patterns, and the average cost of claims. The IBNR reserves are calculated using
a company derived formula based primarily upon premium, which is validated through a close examination of reserve run-out experience.

The
claim reserves are related to group life and group and individual disability products offered by our Insurance Services segment. The following table sets forth total claim reserves segregated between reserves associated with life versus disability
products:



|                      |  |               |         |                  |   |

Unlike policy reserves, claim reserves are subject to revision as our current claim experience and
expectations regarding future factors, which may influence claim experience, change. During each quarter, we monitor our emerging claim experience to ensure that the claim reserves remain appropriate and make adjustments to our assumptions based on
actual experience and our expectations regarding future events as appropriate.

Assumptions used to calculate claim reserves may vary by
the age, gender and occupation class of the claimant, the year the claim was incurred, time elapsed since disablement, and specific contract provisions and limitations.

Claim reserves for our disability products are sensitive to assumptions and considerations regarding:



| |  |  | Claim incidence rates for IBNR claim reserves.
| | - |  | ----------------------------------------------



| |  |  | Claim termination rates.
| | - |  | ------------------------



| |  |  | Discount rates used to value expected future claim payments.
| | - |  | ------------------------------------------------------------



| |  |  | The amount of monthly benefit paid to the insured less reinsurance recoveries and other offsets.
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | Expense rates including inflation.
| | - |  | ----------------------------------



| |  |  | Historical delay in reporting of claims incurred.
| | - |  | -------------------------------------------------

Certain of these factors could be materially affected by changes in social perceptions about work ethics,
emerging medical perceptions and legal interpretations regarding physiological or psychological causes of disability, emerging or changing health issues and changes in industry regulation. If there are changes in one or more of these factors or if
actual claims experience is materially inconsistent with our assumptions, we could be required to change our reserves.

Claim reserves for
our group life and AD&D products are established for death claims reported but not yet paid, IBNR for death and waiver claims and waiver of premium benefits. The death claim reserve is based on the actual amount to be paid. The IBNR reserve is
calculated using historical information, and the waiver of premium benefit is calculated using a tabular reserve method that takes into account company experience and published industry tables.

Trends in Key Assumptions

Key
assumptions affecting our reserve calculations are (1) the discount rate, (2) claim termination rate and (3) the claim incidence rate for policy reserves and IBNR claim reserves.

Reserve discount rates for newly incurred claims are reviewed quarterly and, if necessary, are adjusted to reflect our current and expected net
investment yields. The discount rate used to calculate GAAP reserves for newly incurred long term disability claims decreased to 5.00% for the first quarter of 2008 from 5.35% for the fourth quarter of 2007. Based on our current size, a 25 basis
point decrease in the discount rate would result in a short-term increase of approximately $2 million per quarter of benefits to policyholders, and a corresponding decrease to pre-tax earnings. Offsetting adjustments to group insurance premium rates
can take from one to three years given that most new contracts have rate guarantees in place.

Claim termination rates can vary widely from
quarter to quarter. The claim termination assumptions used in determining our reserves represent our expectation for claim terminations over the life of our block of business and will vary from actual experience in any one quarter. In the first
quarter of 2008, while we have experienced some variation in our claim termination experience, we have not seen any prolonged or systemic change that would indicate a sustained underlying trend that would affect the claim termination rates used in
the calculation of reserves.

In 2007, we adopted a new group life waiver table; the Society of Actuaries Table 2005, to be used in the
calculation of reserves for group life waiver claims incurred in 2007 and later. Adoption of this table resulted in a reduction in the amount of reserves established for new group life waiver claims of $7.3 million for the first quarter of 2008, and
$15.5 million for the last nine months of 2007 compared to the reserves that would have been established using the prior table.

In 2007,
as a result of continued favorable recovery patterns for our group long term disability insurance, partially offset by the recognition of the unique characteristics of a certain group, we released incurred but not reported reserves totaling $13.5
million.

In 2007, we adjusted the calculation of the incurred but not reported reserves related to pending group life waiver claims as a
result of continued redundancy in the reserve. This resulted in a decrease in reserves of $6.0 million. There were no similar reserve reclasses in 2006 or 2005.

In 2007, we adjusted the termination assumptions associated with a small block of group long term disability reported reserves due to prolonged unfavorable reserve run-out experience for the block. This resulted in an
increase in reserves of $16.8 million. There were no similar reserve increases in 2006 or 2005.

In 2006, we did adjust the claim
termination rate assumptions for a small block of individual disability claims in light of a recently released industry table. This resulted in an increase in reserves of $6 million. These



43

##### Table of Contents

assumptions were further refined in 2007 and resulted in an additional increase in reserves of $7.4 million. Our block of business is relatively small, and,
as a result, we view the new industry table as more credible for establishing reserve levels compared solely to our own experience. We will continue to monitor our developing experience in light of the availability of the new industry table and, if
necessary, will adjust reserves accordingly.

Claim incidence rates, which affect our policy reserves and IBNR claim reserves, can also
vary widely from quarter to quarter. Overall, we have not seen any prolonged or systemic change that would indicate a sustained underlying trend that would affect the claim incidence rates used in the calculation of policy reserves or IBNR claim
reserves.

We monitor the adequacy of our reserves relative to our key assumptions. In our estimation, scenarios based on reasonably
possible variations in claim termination assumptions could produce a percentage change in reserves for our group insurance lines of business of approximately +/- 0.2% or $9 million. However, given that claims experience can fluctuate widely from
quarter to quarter, significant unanticipated changes in claim termination rates over time could produce a change in reserves for our group insurance lines outside of this range.

There have been no material changes in market risks faced by StanCorp since those reported in our annual report on Form 10-K for the year ended December 31, 2007.



|ITEM 4: | CONTROLS AND PROCEDURES
|------- | -----------------------

(a)Evaluation of
disclosure controls and procedures. Management of StanCorp has evaluated, under the supervision and with the participation of our chief executive officer and chief financial officer, the effectiveness of our disclosure controls and
procedures, (as defined by the Securities Exchange Act of 1934 Rules 13a-15(c) and 15-d-15(c)) as of the end of the period covered by this report. Based on this evaluation, the chief executive officer and chief financial officer have concluded
that our disclosure controls and procedures were effective at March 31, 2008, and designed to provide reasonable assurance that material information relating to us and our consolidated subsidiaries is recorded, processed, summarized and
reported within the time periods specified in the Securities and Exchange Commissions rules and forms, and is accumulated and communicated to management, including our chief executive officer and chief financial officer, as appropriate, to
allow timely decisions regarding required disclosure. Mr. Chadee joined the Company as senior vice president and chief financial officer in April 2008, and therefore was not the chief financial officer at March 31, 2008.

(b)Changes in internal control. There were no changes in our internal control over financial reporting that occurred during the last fiscal
quarter that have materially affected, or are reasonably likely to affect materially, our internal control over financial reporting.

StatementsCondensed Notes to Unaudited Consolidated Financial StatementsNote 9, Contingencies and Commitments.



|ITEM 1A: | RISK FACTORS
|-------- | ------------

Risk factors that may affect our
business are as follows:



| |  |  | Our reserves for future policy benefits and claims related to our current and future business, as well as reserves related to businesses we may acquire in the
future, may prove to be inadequateFor certain of our product lines, we establish and carry as a liability actuarially determined reserves that are calculated to meet our obligations for future policy benefits and claims. These reserves do
not represent an exact calculation of our future benefit liabilities, but are instead estimates based on assumptions, which can be materially affected by changes in the national or regional economy, changes in social perceptions about work ethics,
emerging medical perceptions regarding physiological or psychological causes of disability, emerging or changing health issues and changes in industry regulation. Claims experience on our products can fluctuate widely from period to period. If
actual events vary materially from our assumptions used when establishing the reserves to meet our obligations for future policy benefits and claims, we may be required to increase our reserves, which could have a material adverse effect on our
business, financial position, results of operations or cash flows.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Differences between actual claims experience and underwriting and reserving assumptions may adversely affect our financial resultsOur long term
disability products provide coverage for claims incurred during the policy period. Generally, group policies offer rate guarantees for periods from one to three years. While we can prospectively re-price and re-underwrite coverages at the end of
these guarantee periods, we must pay benefits with respect to claims incurred during these periods without being able to increase guaranteed premium rates during these periods. Historically, approximately 50% of all claims filed under our long term
disability policies close within 24 months. However, claims caused by more severe disabling conditions may be paid over much longer periods, including, in some cases, up to normal retirement age or longer. Longer duration claims, in addition to a
higher volume of claims than we expect, expose us to the possibility that we may pay benefits in excess of the amount that we anticipated when the policy was underwritten. The profitability of our long term disability products is thus subject to
volatility resulting from the difference between our actual claims experience and our assumptions at the time of underwriting and from changes in economic conditions.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We are exposed to concentration risk on our group life insurance businessDue to the nature of group life insurance coverage, we are subject to
geographical concentration risk from the occurrence of a catastrophe.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Catastrophic losses from a disease pandemic could have an adverse effect on usOur life insurance operations are exposed to the risk of loss from an
occurrence of catastrophic mortality caused by a disease pandemic, such as could arise from the avian flu, which could have a material adverse effect on our business, financial position, results of operations or cash flows.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Catastrophic losses from terrorism or other factors could have an adverse effect on usAn occurrence of a significant catastrophic event, including
natural disasters, terrorism, or other disasters, or a change in the nature and availability of reinsurance and catastrophe reinsurance, could have a material adverse effect on our business, financial position, results of operations or cash flows.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We may be exposed to disintermediation risk during periods of increasing interest ratesIn periods of increasing interest rates, withdrawals of annuity
contracts may increase as policyholders seek to invest in investments with higher perceived returns. This process, referred to as
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



46

##### Table of Contents

| | disintermediation, may lead to cash outflows. These outflows may require investment assets to be sold at a time when the prices of those assets are adversely
affected by the increase in interest rates, which may result in realized investment losses. A significant portion of our investment portfolio consists of commercial mortgage loans, which are relatively illiquid, thus increasing our liquidity risk in
the event of disintermediation during a period of rising interest rates.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our profitability may be adversely affected
by declining interest ratesDuring periods of declining interest rates, annuity products may be relatively more attractive investments, resulting in increases in the percentage of policies remaining in force from year to year during a
period when our new investments carry lower returns. During these periods, lower returns on our investments could prove inadequate for us to meet contractually guaranteed minimum payments to holders of our annuity products. In addition, the
profitability of our life and disability insurance products can be affected by declining interest rates. A factor in pricing our insurance products is prevailing interest rates. Longer duration claims and premium rate guarantee periods can expose us
to interest rate risk when portfolio yields are less than those assumed when pricing these products. Mortgages and bonds in our investment portfolio are more likely to be prepaid or redeemed as borrowers seek to borrow at lower interest rates, and
we may be required to reinvest those funds in lower interest-bearing investments.



| |  |  | Our investment portfolio is subject to risks of market value fluctuations, defaults, delinquencies and liquidityOur general account investments
primarily consist of fixed maturity securities, commercial mortgage loans and real estate. The market values of our investments vary with changing economic and market conditions and interest rates. In addition, we are subject to default risk on our
fixed maturity securities portfolio, and delinquency and default risk on our commercial mortgage loans. Our commercial mortgage loans are relatively illiquid. We may have difficulty selling commercial mortgage loans at attractive prices, in a timely
manner, or both if we require significant amounts of cash on short notice.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our business is subject to significant competitionEach of our business segments faces competition from other insurers and financial services companies,
such as banks, broker-dealers, mutual funds, and managed care providers for employer groups, individual consumers and distributors. Since many of our competitors have greater financial resources, offer a broader array of products and, with respect
to other insurers, may have higher financial strength ratings than we do, the possibility exists that any one of our business segments could be adversely affected, which in turn could have a material adverse effect on our business, financial
position, results of operations or cash flows.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A significant downgrade in our financial strength ratings may negatively affect our businessFinancial strength ratings, which rate our claims paying
ability, are an important factor in establishing the competitive position of insurance companies. Ratings are important to maintaining public confidence in our company and in our ability to market our products. Rating organizations continually
review the financial performance and condition of insurance companies, including our company. A significant ratings downgrade could increase our surrender levels and could adversely affect our ability to market our products and thereby have a
material adverse effect on our business, financial position, results of operations or cash flows.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our profitability may be affected by changes in state and federal regulationOur business is subject to comprehensive state regulation and supervision
throughout the United States. While we cannot predict the impact of potential or future state or federal legislation or regulation on our business, future laws and regulations, or the interpretation thereof, could have a material adverse effect on
our business, financial position, results of operations or cash flows.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our business is subject to litigation riskIn the normal course of business, we are a plaintiff or defendant in actions arising out of our insurance
business and investment operations. We are from time to time involved in various governmental and administrative proceedings. While the outcome of any pending or future litigation cannot be predicted, as of the date hereof, we do not believe that
any pending litigation will have a material adverse effect on our results of operations and financial
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | condition. However, no assurances can be given that such litigation would not materially and adversely affect our business, financial position, results of
operations or cash flows.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The concentration of our investments in California may subject us to losses resulting from an economic downturn as well as certain catastrophes in this
stateOur commercial mortgage loans are concentrated in the western region of the U.S., particularly in California. Due to this concentration, we are exposed to potential losses resulting from the risk of an economic downturn in California
as well as to certain catastrophes, such as earthquakes and fires, which may affect the region. Although we diversify our commercial mortgage loan portfolio within California by both location and type of property in an effort to reduce earthquake
exposure, such diversification may not eliminate the risk of such losses, which could have a material adverse effect on our business, financial position, results of operations or cash flows.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We may be exposed to environmental liability from our commercial mortgage loan and real estate investmentsAs a commercial mortgage lender, we
customarily conduct environmental assessments prior to making commercial mortgage loans secured by real estate and before taking title through foreclosure to real estate collateralizing delinquent commercial mortgage loans held by us. Based on our
environmental assessments, we believe that any compliance costs associated with environmental laws and regulations or any remediation of affected properties would not have a material adverse effect on our results of operations or financial
condition. However, we cannot provide assurance that material compliance costs will not be incurred by us.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | As a holding company, we depend on the ability of our subsidiaries to transfer funds to us in sufficient amounts to pay dividends to shareholders, make payments
on debt securities and meet our other obligationsWe are a holding company for our insurance and asset management subsidiaries and do not have any significant operations of our own. Dividends and permitted payments from our subsidiaries are
our principal source of cash to meet our other obligations, pay dividends to shareholders and make payments on debt securities. As a result, our ability to pay dividends to shareholders and interest payments on debt securities primarily will depend
upon the receipt of dividends and other distributions from our subsidiaries.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Many of our subsidiaries are non-insurance
businesses and have no regulatory restrictions on dividends. Our insurance subsidiaries, however, are regulated by insurance laws and regulations that limit the maximum amount of dividends, distributions and other payments that they could declare
and pay to us without prior approval of the states in which the subsidiaries are domiciled. Under Oregon law, Standard Insurance Company may pay dividends only from the earned surplus arising from its business. Oregon law gives the Director of the
Oregon Department of Consumer and Business ServicesInsurances Division (Oregon Insurance Division) broad discretion regarding the approval of dividends. Oregon law requires us to receive the prior approval of the Oregon Insurance
Division to pay a dividend if such dividend exceeds certain statutory limitations; however, it is at the Oregon Insurance Divisions discretion to request prior approval of dividends at any time. See Part I, Item 2, Managements
Discussion and Analysis of Financial Condition and Results of OperationsCapital ManagementDividends from Insurance Subsidiary.



| |  |  | Our business may be affected by employment and wage growthTwo factors in the growth of StanCorps group insurance and retirement plans businesses
are the employment levels, and salary and wage growth of its employer groups. A reduction in either of these factors may affect premium levels for our group businesses and revenues in our retirement plans business.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our profitability may be adversely affected by declining equity marketsSustained equity market declines could result in decreases in the value of the
assets under administration in our retirement plans, which could reduce our ability to earn administrative fee income derived from the value of those assets.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

On May 7, 2007, the board of directors authorized a share repurchase program of up to
6.0 million shares of StanCorp common stock. The share repurchase program will be effected in the open market or in negotiated transactions through December 31, 2008. The share repurchase program replaced our previous share repurchase
program, which had 1.2 million shares remaining that expired upon authorization of the new program.

Included in the share repurchases
during the first quarter of 2008 were 4,065 shares of common stock acquired from executive officers to cover tax liabilities of these officers resulting from the release of performance-based shares at a total cost of $0.2 million for a volume
weighted-average price of $50.78 per common share, which reflects the market price on the transaction date.

In addition, the declaration
or payment of dividends would be restricted if StanCorp elects to defer interest payments on its junior subordinated debt. If the Company elected to defer interest payments, the dividend restriction would be in place during the deferral period,
which cannot exceed five years. See Part I, Item 2, Managements Discussion and Analysis of Financial Conditions and Results of OperationsCapital ManagementDividends to Shareholders.

|ITEM 5: | OTHER INFORMATION
|------- | -----------------

On May 5, 2008, at the
Annual meeting of Shareholders, the Shareholders approved proposals to approve amendments to the Amended 2002 Stock Incentive Plan and to approve the Amended and Restated Shareholder Rights Plan. The changes to the Shareholder Rights Plan will
become effective April 20, 2009 upon adoption by the board of directors. The following summarizes the approved changes to the two agreements.



| |  |  | The amendments to the Amended 2002 Stock Incentive Plan included increasing the shares of common stock available for issuance by 1.9 million shares of which
400,000 are available for stock awards other than options. It also included increasing the maximum dollar-denominated performance awards granted to only one person in any year from $2 million to $3 million.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Amended Rights Plan modified the existing plan in several ways that are considered progressive or shareholder friendly:
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | The Amended Rights Plan increased the stock ownership threshold of a potential acquirer that would trigger the issuance of the Rights under the Amended Rights Plan
from 15 percent to 20 percent.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Amended Rights Plan has a three-year term, compared to the existing rights plan, which has a ten-year term that is due to expire in April 2009.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The independent directors will assess on an annual basis whether the Amended Rights Agreement remains in the best interest of Shareholders.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Amended Rights Plan also includes a Qualifying Offer provision that would, under certain circumstances, permit holders of at least 10 percent of the
outstanding shares of common stock to request that a special meeting be convened for the purpose of voting on whether to exempt the offer from the Amended Rights Plan.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

A copy of the agreements are attached hereto as Exhibit 10.1 and 10.2 and furnished herewith.

At the May 2008 Board of Directors meeting, the Board approved revisions to the Standard Insurance Company Supplemental Retirement Plan for the Senior
Officer Management Group. A copy of the agreement is attached hereto as Exhibit 10.3 and furnished herewith.
