CONDENSED NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

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.

1. ORGANIZATION, PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION

StanCorp, headquartered in Portland, Oregon, is a holding company and conducts business through wholly-owned operating subsidiaries throughout the United States (“U.S”). Through its subsidiaries, StanCorp has the authority to underwrite insurance products in all 50 states. StanCorp operates through two segments: Insurance Services and Asset Management as well as an Other category. See “Note 5—Segments.”

StanCorp has the following wholly-owned operating subsidiaries: Standard Insurance Company (“Standard”), The Standard Life Insurance Company of New York, Standard Retirement Services, Inc. (“Standard Retirement Services”), StanCorp Equities, Inc. (“StanCorp Equities”), StanCorp Mortgage Investors, LLC (“StanCorp Mortgage Investors”), StanCorp Investment Advisers, Inc. (“StanCorp Investment Advisers”), StanCorp Real Estate, LLC (“StanCorp Real Estate”), Standard Management, Inc. (“Standard Management”) and Adaptu, LLC (“Adaptu”).

Standard, the Company’s largest subsidiary, underwrites group and individual disability insurance and annuity products, group life and accidental death and dismemberment (“AD&D”) insurance, and provides group dental and group vision insurance, absence management services and retirement plan products. Founded in 1906, Standard is domiciled in Oregon, licensed in all states except New York, and licensed in the District of Columbia and the U.S. territories of Guam and the Virgin Islands.

The Standard Life Insurance Company of New York was organized in 2000 and is licensed to provide group long term and short term disability insurance, individual disability insurance, group life and AD&D insurance and group dental insurance in New York.

The Standard is a service mark of StanCorp and its subsidiaries and is used as a brand mark and marketing name by Standard and The Standard Life Insurance Company of New York.

Standard Retirement Services administers and services StanCorp’s retirement plans group annuity contracts and trust products. Retirement plan products are offered in all 50 states through Standard or Standard Retirement Services.

StanCorp Equities is a limited broker-dealer and member of the Financial Industry Regulatory Authority. StanCorp Equities serves as principal underwriter and distributor for group variable annuity contracts issued by Standard and as the broker of record for certain retirement plans using the trust platform. StanCorp Equities carries no customer accounts but provides supervision and oversight for the distribution of group variable annuity contracts and of the sales activities of all registered representatives employed by StanCorp Equities and its affiliates.

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

StanCorp Real Estate is a property management company that owns and manages the Hillsboro, Oregon home office properties and other properties held for investment and held for sale. StanCorp Real Estate also manages the Portland, Oregon home office properties.

Standard Management has owned and managed certain real estate properties held for sale.

Adaptu provides an online service to help users plan and manage their financial lives.

Standard holds interests in low-income housing tax credit investments. These interests do not meet the requirements for consolidation under existing accounting standards, and thus the Company’s interests in the low-income housing tax credit investments are accounted for under the equity method of accounting. The total investment in these interests was $181.8 million and $128.0 million at June 30, 2012 and December 31, 2011, respectively.

In October 2010, the Financial Accounting Standards Board (‘FASB’) issued Accounting Standards Update (‘ASU’) No. 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts. ASU No. 2010-26 amends the codification guidance for insurance entities to eliminate the diversity of accounting treatment related to deferred acquisition costs (‘DAC’). The Company has adopted this standard retrospectively as of January 1, 2012, and comparative financial statements of prior periods have been adjusted.

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. Intercompany balances and transactions have been eliminated on a consolidated basis. 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 June 30, 2012, and for the results of operations for the three and six months ended June 30, 2012 and 2011, and cash flows for the six months ended June 30, 2012 and 2011. Interim results for the three and six months ended June 30, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. This report should be read in conjunction with

6

the Company’s 2011 annual report on Form 10-K and the Company’s current report on Form 8-K dated July 18, 2012 which updated certain items in the Company’s annual report on Form 10-K for the retrospective adoption of ASU No. 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts.

2. NET INCOME PER COMMON SHARE

Net income per basic 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 stock award 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.

The following table sets forth the calculation of net income per basic and diluted weighted-average common shares outstanding:

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2011		2012		2011
Net income (in millions)	$	20.0	$	17.8	$	55.2	$	51.1
Basic weighted-average common shares outstanding		44,266,776		44,868,646		44,296,945		45,398,006
Stock options		87,944		187,826		106,584		219,275
Stock awards		—		—		3,796		1,996
Diluted weighted-average common shares outstanding		44,354,720		45,056,472		44,407,325		45,619,277
Net income per common share:
Net income per basic common share	$	0.45	$	0.40	$	1.25	$	1.12
Net income per diluted common share		0.45		0.40		1.24		1.12
Antidilutive shares not included in net income per diluted common share calculation		2,199,670		1,367,485		2,139,650		1,270,435

3. SHARE-BASED COMPENSATION

The Company has two active share-based compensation plans: the 2002 Stock Incentive Plan (“2002 Plan”) and the 1999 Employee Share Purchase Plan (“ESPP”). The 2002 Plan authorizes the Board of Directors to grant incentive or non-statutory stock options and stock awards to eligible employees and certain related parties. Of the 4.8 million shares of common stock authorized for the 2002 Plan, 0.9 million shares or options for shares remain available for grant at June 30, 2012. The Company’s ESPP allows eligible employees to purchase StanCorp common stock at a discount. Of the 3.5 million shares authorized for the ESPP, 1.7 million shares remain available for issuance at June 30, 2012.

The following table sets forth the total compensation cost and related income tax benefit under the Company’s share-based compensation plans:

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2011		2012		2011
	(In millions)
Compensation cost	$	1.6	$	1.5	$	3.9	$	3.1
Related income tax benefit		0.5		0.5		1.3		1.1

The Company has provided three types of share-based compensation pursuant to the 2002 Plan: option grants, stock award grants and director stock grants.

Option Grants

Options are granted to officers and certain non-officer employees. Options are granted with an exercise price equal to the closing market price of StanCorp common stock on the grant date. Options generally vest in equal installments on the first four anniversaries of the vesting reference date.

The Company granted 225,133 and 236,785 options for the first six months of 2012 and 2011, respectively, at a weighted-average exercise price of $39.58 and $45.46, respectively. The fair value of each option award granted was estimated using the Black-Scholes option pricing model as of the grant date. The weighted-average grant date fair value of options granted for the first six months of 2012 and 2011 was $14.44 and $17.48, respectively.

The compensation cost of stock options is recognized over the vesting period, which is also the period over which the grantee must provide services to the Company. At June 30, 2012, the total compensation cost related to unvested option awards that had not yet been recognized in the financial statements was $7.1 million. This compensation cost will be recognized over a weighted-average period of 2.7 years.

7

Stock Award Grants

The Company grants performance-based stock awards (“Performance Shares”) to designated senior officers. The payout for these awards is based on the Company’s financial performance over a three-year period. Performance Share grants represent the maximum number of shares of StanCorp common stock issuable to the designated senior officers. The actual number of shares issued at the end of the performance period is based on satisfaction of employment and Company financial performance conditions, with a portion of the shares withheld to cover required tax withholding. Under the 2002 Plan, the Company had 0.6 million shares available for issuance as stock award grants at June 30, 2012.

The Company granted 179,818 and 116,978 Performance Shares for the first six months of 2012 and 2011, respectively.

The Company issued 9,899 and 4,906 shares of StanCorp common stock for the first six months of 2012 and 2011, respectively, to redeem Performance Shares that vested following the 2011 and 2010 performance periods, net of Performance Shares withheld to cover the required taxes.

The fair value of the Performance Shares is determined based on the closing market price of StanCorp common stock on the grant date.

The compensation cost that the Company will ultimately recognize as a result of these stock awards is dependent on the Company’s financial performance. Assuming that the maximum performance is achieved for each performance goal, $15.3 million in additional compensation cost would be recognized through 2014. Assuming that the target performance is achieved for each performance goal, $8.1 million in additional compensation cost would be recognized through 2014. Assuming that the maximum performance is achieved this cost is would be recognized over a weighted-average period of 1.8 years.

Director Stock Grants

Effective May 7, 2012, each director who is not an employee of the Company receives annual compensation of StanCorp common stock with a fair value equal to $100,000 based on the closing market price of StanCorp common stock on the day of the annual shareholders meeting.

The Company issued 9,489 and 10,399 shares of StanCorp common stock for the second quarters of 2012 and 2011, respectively, related to the annual Director stock grant.

Employee Share Purchase Plan

The Company’s ESPP allows eligible employees to purchase StanCorp common stock at a 15% discount of the lesser of the closing market price of StanCorp common stock on either the commencement date or the final date of each six-month offering period. 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.

The following table sets forth the compensation cost and related income tax benefit under the Company’s ESPP:

4. RETIREMENT BENEFITS

Pension 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 the Company, and the agent pension plan is for former field employees and agents. The defined benefit pension plans provide benefits based on years of service and final average pay. Both plans are sponsored by Standard and administered by Standard Retirement Services and are closed to new participants. Participation in the defined benefit pension plans is generally limited to eligible employees whose date of employment began before 2003.

Under the employee pension plan, a participant is entitled to a normal retirement benefit once the participant reaches age 65. A participant can also receive a normal, unreduced retirement benefit once the sum of his or her age plus years of service is at least 90.

The Company recognizes the funded status of the pension plans as an asset or liability on the balance sheet. The funded status is measured as the difference between the fair value of the plan assets and the projected benefit obligation as of the year-end balance sheet date. While the Company is not obligated to make any contributions to its pension plans for 2012, it does evaluate the funding status of these plans annually in the fourth quarter.

Postretirement Benefits Other Than Pensions

Standard sponsors and administers a postretirement benefit plan that includes medical and prescription drug benefits. A group term life insurance benefit was curtailed as of December 31, 2011. 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. Participation in the postretirement benefit plan is limited to employees who had reached the age of 40, or whose combined age and length of service was equal to or greater than 45 years as of January 1, 2006. This plan is closed to new participants.

The Company recognizes the funded status of the postretirement benefit plan as an asset or liability on the balance sheet. The funded status is measured as the difference between the fair value of the plan assets and the accumulated benefit obligation.

Deferred Compensation Plans

Eligible employees are covered by a qualified deferred compensation plan sponsored by Standard 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 $2.3 million and $2.7 million for the second quarters of 2012 and 2011, respectively, and $5.4 million and $5.8 million for the first six months of 2012 and 2011, respectively.

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 $10.3 million at June 30, 2012 and $10.7 million at December 31, 2011.

Non-Qualified Supplemental Retirement Plan

Eligible executive officers are covered by a non-qualified supplemental retirement plan (“non-qualified plan”). Under the non-qualified plan, a participant is entitled to a normal retirement benefit once the participant reaches age 65. A participant can also receive a normal, unreduced retirement benefit once the sum of his or her age plus years of service is at least 90. The Company recognizes the unfunded status of the non-qualified plan in other liabilities on the balance sheet. The unfunded status was $28.8 million and $28.5 million at June 30, 2012 and December 31, 2011, respectively. Expenses were $0.7 million and $0.7 million for the second quarters of 2012 and 2011, respectively, and were $1.3 million and $1.4 million for the first six months of 2012 and 2011, respectively. The net loss and prior service cost, net of tax, excluded from the net periodic benefit cost and reported as a component of accumulated other comprehensive income was $5.4 million and $5.7 million at June 30, 2012 and December 31, 2011, respectively.

5. SEGMENTS

StanCorp operates through two reportable segments: Insurance Services and Asset Management, as well as an Other category. Subsidiaries, or operating segments, have been aggregated to form the Company’s reportable 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 AD&D insurance, group dental and group vision insurance, and absence management services. The Asset Management segment offers full-service 401(k) plans, 403(b) plans, 457 plans, defined benefit plans, money purchase pension plans, profit sharing plans and non-qualified deferred compensation products and services. This segment also offers investment advisory and management services, financial planning services, commercial mortgage loan origination and servicing, individual fixed-rate annuity products, group annuity contracts and retirement plan trust products. The Other category includes return on capital not allocated to the product segments, holding company expenses, operations of certain unallocated subsidiaries, interest on debt, unallocated expenses, net capital gains and losses related to the impairment or the disposition of the Company’s invested assets and adjustments made in consolidation.

Intersegment revenues are comprised of administrative fee revenues charged by the Asset Management segment to manage the fixed maturity securities—available-for-sale (“fixed maturity securities”) and commercial mortgage loan portfolios for the Company’s insurance subsidiaries.

6. FAIR VALUE

Assets and liabilities recorded at fair value are disclosed using a three-level hierarchy. 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 the Company’s 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 the Company 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.

There are three types of valuation techniques used to measure assets and liabilities recorded at fair value:

• The market approach, which uses prices or other relevant information generated by market transactions involving identical or comparable assets or liabilities.

• The income approach, which uses the present value of cash flows or earnings.

• The cost approach, which uses replacement costs more readily adaptable for valuing physical assets.

The Company uses both the market and income approach in its fair value measurements. These measurements are discussed in more detail below.

The following table sets forth the estimated fair value and the carrying value of each financial instrument:

Financial Instruments Not Recorded at Fair Value

The Company did not elect to measure and record commercial mortgage loans, policy loans, other policyholders funds that are investment-type contracts, short-term debt, or long-term debt at fair value on the consolidated balance sheets.

For disclosure purposes, the fair values of commercial mortgage loans were estimated using an option-adjusted discounted cash flow valuation. The valuation includes both observable market inputs and estimated model parameters.

Significant observable inputs to the valuation include:

• Indicative quarter-end pricing for a package of loans similar to those originated by the Company near quarter-end.

• U.S. Government treasury yields.

• Indicative yields from industrial bond issues.

• The contractual terms of nearly every mortgage subject to valuation.

Significant estimated parameters include:

• A liquidity premium that is estimated from historical loan sales and is applied over and above base yields.

• Adjustments in interest rate spread based on an aggregate portfolio loan-to-value ratio, estimated from historical differential yields with respect to loan-to-value ratios.

• Projected prepayment activity.

For policy loans, the carrying value represents historical cost but approximates fair value. While potentially financial instruments, policy loans are an integral component of the insurance contract and have no maturity date.

The fair value of other policyholder funds that are investment-type contracts was calculated using the income approach in conjunction with the cost of capital method. The parameters used for discounting in the calculation were estimated using the perspective of the principal market for the contracts under consideration. The principal market consists of other insurance carriers with similar contracts on their books.

The fair value for short-term and long-term debt was predominantly based on quoted market prices as of June 30, 2012 and December 31, 2011, and trades occurring close to June 30, 2012 and December 31, 2011.

Financial Instruments Measured and Recorded at Fair Value

Fixed maturity securities, Standard & Poor’s (“S&P”) 500 Index call options (“S&P 500 Index options”) and index-based interest guarantees embedded in indexed annuities (“index-based interest guarantees”) are recorded at fair value on a recurring 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, in net investment income for S&P 500 Index options and in interest credited for index-based interest guarantees.

Separate account assets represent segregated funds held for the exclusive benefit of contract holders. The activities of the account primarily relate to participant-directed 401(k) contracts. Separate account assets are recorded at fair value on a recurring basis, with changes in fair value recorded in separate account liabilities. Separate account assets consist of mutual funds. The mutual funds’ fair value is determined through Level 1 and Level 2 inputs. The majority of the separate account assets are valued using quoted prices in an active market with the remainder of the assets valued using quoted prices from an independent pricing service. The Company reviews the values obtained from the pricing service for reasonableness through analytical procedures and performance reviews.

16

Fixed maturity securities are comprised of the following classes:

• U.S. government and agency bonds.

• U.S. state and political subdivision bonds.

• Foreign government bonds.

• Corporate bonds.

• S&P 500 Index options.

The fixed maturity securities are diversified across industries, issuers and maturities. The Company calculates fair values for all classes of fixed maturity securities using valuation techniques described below. They are placed into three levels depending on the valuation technique used to determine the fair value of the securities.

The Company uses an independent pricing service to assist management in determining the fair value of these assets. The pricing service incorporates a variety of information observable in the market in its valuation techniques, including:

• Reported trading prices.

• Benchmark yields.

• Broker-dealer quotes.

• Benchmark securities.

• Bids and offers.

• Credit ratings.

• Relative credit information.

• Other reference data.

The pricing service also takes into account perceived market movements and sector news, as well as a bond’s terms and conditions, including any features specific to that issue that may influence risk, and thus marketability. Depending on the security, the priority of the use of observable market inputs may change as some observable market inputs may not be relevant or additional inputs may be necessary. The Company generally obtains one value from its primary external pricing service. On a case-by-case basis, the Company may obtain further quotes or prices from additional parties as needed.

The pricing service provides quoted market prices when available. Quoted prices are not always available due to bond market inactivity. The pricing service obtains a broker quote when sufficient information, such as security structure or other market information, is not available to produce a valuation. Valuations and quotes obtained from third party commercial pricing services are non-binding and do not represent quotes on which one may execute the disposition of the assets.

The significant unobservable inputs used in the fair value measurement of the reporting entity’s bonds are valuations and quotes received from secondary pricing service, analytical reviews and broker quotes. Significant increases or decreases in any of those inputs in isolation would result in a significantly lower or higher fair value measurement. Generally, a change in the assumption used for the pricing evaluation is accompanied by a directionally similar change in the assumption used for the methodologies.

The Company performs control procedures over the external valuations at least quarterly through a combination of procedures that include an evaluation of methodologies used by the pricing service, analytical reviews and performance analysis of the prices against statistics and trends, back testing of sales activity and maintenance of a securities watch list. As necessary, the Company compares prices received from the pricing service to prices independently estimated by the Company utilizing discounted cash flow models or through performing independent valuations of inputs and assumptions similar to those used by the pricing service in order to ensure prices represent a reasonable estimate of fair value. Although the Company does identify differences from time to time as a result of these validation procedures, the Company did not make any significant adjustments as of June 30, 2012 or December 31, 2011.

S&P 500 Index options and certain fixed maturity securities were valued using Level 3 inputs. The Level 3 fixed maturity securities were valued using matrix pricing, independent broker quotes and other standard market valuation methodologies. The fair value was determined using inputs that were not observable or could not be derived principally from, or corroborated by, observable market data. These inputs included assumptions regarding liquidity, estimated future cash flows and discount rates. Unobservable inputs to these valuations are based on management’s judgment or estimation obtained from the best sources available. The Company’s valuations maximize the use of observable inputs, which include an analysis of securities in similar sectors with comparable maturity dates and bond ratings. Broker quotes are validated by management for reasonableness in conjunction with information obtained from matrix pricing and other sources.

The Company calculates the fair value for its S&P 500 Index options using the Black-Scholes option pricing model and parameters derived from market sources. The Company’s valuations maximize the use of observable inputs, which include direct price quotes from the Chicago Board Options Exchange (“CBOE”) and values for on-the-run treasury securities and London Interbank Offered Rate (“LIBOR”) as reported by Bloomberg. Unobservable inputs are estimated from the best sources available to the Company and include estimates of future gross dividends to be paid on the stocks underlying the S&P 500 Index, estimates of bid-ask spreads, and estimates of implied volatilities on options. Valuation parameters are calibrated to replicate the actual end-of-day market quotes for options trading on the CBOE. The Company performs additional validation procedures such as the daily observation of market activity and conditions and the tracking and analyzing of actual quotes provided by banking counterparties each time the Company purchases options from them. Additionally, in order to help validate the values derived through the procedures noted above, the Company obtains indicators of value from representative investment banks.

The Company uses the income approach valuation technique to determine the fair value of index-based interest guarantees. 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 declarations significantly influence the calculation. Index-based interest guarantees are included in the other policyholder funds line on the Company’s consolidated balance sheet.

While valuations for the S&P 500 Index options are sensitive to a number of variables, valuations for S&P 500 Index options purchased are most sensitive to changes in the estimates of bid ask spreads, or the S&P 500 Index value, and the implied volatilities of this index. Significant fluctuations in any of those inputs in isolation would result in a significantly lower or higher fair value measurement. Generally, an increase or decrease used in the assumption for the implied volatilities and in the S&P 500 Index value would result in a directionally similar change in the fair value of the asset.

Valuations for the index-based interest guarantees are sensitive to a number of variables, but are most sensitive to the S&P 500 Index value, the implied volatilities of this index, and LIBOR as reported by Bloomberg. Generally, a significant increase or decrease used in the assumption for the implied volatilities and in the S&P 500 Index value would result in a directionally similar change, while an increase or decrease in LIBOR would result in a directionally opposite change in the fair value of the liability.

Valuations for commercial mortgage loans and real estate owned measured on a nonrecurring basis are sensitive to a number of variables, but are most sensitive to the capitalization rate. Generally, an increase or decrease used in the assumption for the capitalization rate would result in a directionally similar change in the fair value of the asset.

Quantitative information regarding significant unobservable inputs used in Level 3 valuation of assets and liabilities measured and recorded at fair value is as follows:

	June 30, 2012 (Dollars in millions)
	Fair Value		Valuation Technique	Unobservable Input	Range of inputs
S&P 500 Index options	$	12.4	Black-Scholes Option Pricing model	Various assumptions	(a)
Index-based interest guarantees		56.0	Discounted Cash Flow	Expected future option purchase	1%-5%
				Various assumptions	(b)
			Black-Scholes Option Pricing model	Various assumptions	(a)
Commercial mortgage loans		55.4	Appraisals	Discount for dated appraisal	0%-50%
			Cash Flows	Capitalization rate (c)	7%-14%
Real estate owned		27.0	Appraisals	Discount for dated appraisal	0%-50%

(a) Represents various assumptions derived from market data, which include estimates of bid ask spreads and the implied volatilities for the S&P 500 index.

(b) Represents various actuarial assumptions which include combined lapse, mortality and withdrawal decrement rates which generally have a range of inputs from 5%-36%.

(c) Capitalization rates are used as an internal analysis in converting the underlying property’s income to an estimated property value.

For all periods disclosed above, fixed maturity securities transferred into Level 3 from Level 2 are the result of the Company being unable to obtain observable assumptions in the market. Fixed maturity securities transferred out of Level 3 into Level 2 are the result of the Company being able to obtain observable assumptions in the market. There were no transfers between Level 1 and Level 2 for the second quarter of 2012 and 2011.

The following table sets forth the changes in unrealized gains (losses) included in net income relating to positions that the Company continued to hold:

	Three Months Ended June  30,						Six Months Ended June  30,
	2012			2011			2012			2011
	(In millions)
Assets:

Liabilities:
Index-based interest guarantees	$	(1.9	)	$	(1.2	)	$	(8.4	)	$	(4.5	)

Changes to the fair value of fixed maturity securities, excluding S&P 500 Index options, were recorded in other comprehensive income. Changes to the fair value of the S&P 500 Index options were recorded to net investment income. Changes to the fair value of the index-based interest guarantees were recorded as interest credited. The interest credited amount included negative interest on policyholder funds due to changes in the Level 3 actuarial assumptions of $1.1 million and $1.5 million for the second quarters and first six months of 2012 and 2011, respectively.

Certain assets and liabilities are measured at fair value on a nonrecurring basis such as impaired commercial mortgage loans with specific allowances for losses and real estate acquired in satisfaction of debt through foreclosure or the acceptance of deeds in lieu of foreclosure on commercial mortgage loans (“real estate owned”). The impaired commercial mortgage loans and real estate owned are valued using Level 3 measurements. These Level 3 inputs are reviewed for reasonableness by management and evaluated on a quarterly basis. The commercial mortgage loan measurements include valuation of the market value of the asset using general underwriting procedures and appraisals. Real estate owned is initially recorded at estimated net realizable value, which includes an estimate for disposal costs. These amounts may be adjusted in a subsequent period as independent appraisals are received.

The following table sets forth the assets measured at fair value on a nonrecurring basis as of June 30, 2012 that the Company continued to hold:

	June 30, 2012
	Total		Level 1		Level 2		Level 3
	(In millions)
Commercial mortgage loans	$	55.4	$	—	$	—	$	55.4
Real estate owned		27.0		—		—		27.0
Total assets measured at fair value on a nonrecurring basis	$	82.4	$	—	$	—	$	82.4

Commercial mortgage loans measured on a nonrecurring basis with a carrying amount of $74.5 million were written down to their fair value of $55.4 million, less selling costs, at June 30, 2012. The specific commercial mortgage loan loss allowance related to these commercial mortgage loans was $24.6 million at June 30, 2012. The real estate owned measured on a nonrecurring basis as of June 30, 2012, and still held at June 30, 2012 had capital losses totaling $0.6 million for the first six months of 2012. Real estate owned measured on a nonrecurring basis represents newly acquired properties or properties whose value has been adjusted based on pending sale or other market information.

The following table sets forth the assets measured at fair value on a nonrecurring basis as of June 30, 2011 that the Company continued to hold:

	December 31, 2011

The following table sets forth the amortized costs and fair values of the Company’s fixed maturity securities by contractual maturity:

	June 30, 2012				December 31, 2011
	Amortized Cost		Fair Value		Amortized Cost		Fair Value
	(In millions)
Due in one year or less	$	746.6	$	761.0	$	632.7	$	645.0

Total fixed maturity securities	$	6,359.4	$	6,977.2	$	6,209.9	$	6,769.5

Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations. Callable bonds without make-whole provisions represented 7.6%, or $533.7 million, of the Company’s fixed maturity securities portfolio at June 30, 2012. At June 30, 2012, the Company did not have any direct exposure to sub-prime or Alt-A mortgages in its fixed maturity securities portfolio. At June 30, 2012, the Company’s foreign government bonds category did not have any direct exposure to euro zone government issued debt. At June 30, 2012, fixed maturity securities issued by investment and commercial banks headquartered in the euro zone represented 0.7%, or $49.9 million, of the Company’s fixed maturity security portfolio. The Company did not hold any fixed maturity securities issued by investment and commercial banks headquartered in Portugal, Ireland, Italy, Greece or Spain at June 30, 2012. There were no impairments on fixed maturity securities related to euro zone exposure during the first six months of 2012.

Gross Unrealized Losses

The following tables set forth the gross unrealized losses and fair value of investments, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position:

	June 30, 2012
	Total				Less than 12 months				12 or more months
	Number		Amount		Number		Amount		Number		Amount
	(Dollars in millions)
Unrealized losses:
Corporate bonds		201	$	6.9		182	$	4.2		19	$	2.7
Fair market value of securities with unrealized losses:
Corporate bonds		201	$	227.9		182	$	197.9		19	$	30.0
	December 31,  2011
	Total				Less than 12 months				12 or more months
	Number		Amount		Number		Amount		Number		Amount
	(Dollars in millions)
Unrealized losses:
Corporate bonds		360	$	20.9		334	$	17.4		26	$	3.5
Fair market value of securities with unrealized losses:
Corporate bonds		360	$	425.3		334	$	398.0		26	$	27.3

The unrealized losses on the investment securities set forth above were primarily due to increases in market interest rates subsequent to their purchase by the Company. Additionally, unrealized losses have been affected by overall economic factors. The Company expects the fair value of these investment securities to recover as the investment securities approach their maturity dates or sooner if market yields for such investment securities decline. The Company does not believe that any of the investment securities are impaired due to credit quality or due to any company or industry specific event. Based on management’s evaluation of the securities and the Company’s intent to hold the securities, and as it is unlikely that the Company will be required to sell the securities, none of the unrealized losses summarized in this table are considered other-than-temporary.

Commercial Mortgage Loans

The Company underwrites mortgage loans on commercial property throughout the United States. In addition to real estate collateral, the Company requires either partial or full recourse on most loans. At June 30, 2012, the Company did not have any direct exposure to sub-prime or Alt-A mortgages in its commercial mortgage loan portfolio.

* Geographic regions obtained from the American Council of Life Insurers Mortgage Loan Portfolio Profile.

Through its concentration of commercial mortgage loans in California, the Company is exposed to potential losses from an economic downturn in California as well as certain catastrophes, such as earthquakes and fires that may affect certain areas of the western region. Borrowers are required to maintain fire insurance coverage to provide reimbursement for any losses due to fire. Management diversifies the 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 the California-based commercial mortgage loans has been substantially below the industry average and consistent with the Company’s experience in other states. The Company does not require earthquake insurance for the properties when it underwrites new loans. However, management does consider the potential for earthquake loss based upon seismic surveys and structural information specific to each property. The Company does not expect a catastrophe or earthquake damage in the western region to have a material adverse effect on its business, financial position, results of operations or cash flows. Currently, the Company’s California exposure is primarily in Los Angeles County, Orange County, San Diego County and the Bay Area Counties. There is a smaller concentration of commercial mortgage loans in the Inland Empire and the San Joaquin Valley where there has been greater economic decline. Due to the concentration of commercial mortgage loans in California, a continued economic decline in California could have a material adverse effect on the Company’s business, financial position, results of operations or cash flows.

The carrying value of commercial mortgage loans represents the outstanding principal balance less a loan loss allowance for probable uncollectible amounts. The commercial mortgage loan loss allowance is estimated based on evaluating known and inherent risks in the loan portfolio and consists of a general and a specific loan loss allowance.

24

Impairment Evaluation

The Company continuously monitors its commercial mortgage loan portfolio for potential nonperformance by evaluating the portfolio and individual loans. Key factors that are monitored are as follows:

• Loan loss experience.

• Delinquency history.

• Debt coverage ratio.

• Loan to value ratio.

• Refinancing and restructuring history.

• Request for forbearance history.

If the analysis above indicates a loan might be impaired, it is further analyzed for impairment through the consideration of the following additional factors:

• Delinquency status.

• Foreclosure status.

• Restructuring status.

• Borrower history.

If it is determined a loan is impaired, a specific allowance is recorded, if necessary.

General Loan Loss Allowance

The general loan loss allowance is based on the Company’s analysis of factors including changes in the size and composition of the loan portfolio, debt coverage ratios, loan to value ratios, actual loan loss experience and individual loan analysis.

Specific Loan Loss Allowance

An impaired commercial mortgage loan is a loan that is not performing to the contractual terms of the loan agreement. A specific allowance for losses is recorded when a loan is considered to be impaired and it is probable that all amounts due will not be collected. The Company also holds specific loan loss allowances on certain performing commercial mortgage loans that it continues to monitor and evaluate. Impaired commercial mortgage loans without specific allowances for losses are those for which the Company has determined that it remains probable that all amounts due will be collected although the timing or nature may be outside the original contractual terms. In addition, for impaired commercial mortgage loans, the Company evaluates the cost to dispose of the underlying collateral, any significant out of pocket expenses the loan may incur and other quantitative information management has concerning the loan. Portions of loans that are deemed uncollectible are written off against the allowance, and recoveries, if any, are credited to the allowance.

The following table sets forth changes in the commercial mortgage loan loss allowance:

	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2012			2011			2012			2011
	(In millions)
Commercial mortgage loan loss allowance:
Beginning balance	$	45.6		$	39.4		$	48.1		$	36.1
Provision		5.1			9.3			6.4			18.0
Charge-offs, net		(5.1	)		(5.2	)		(8.9	)		(10.6	)
Ending balance	$	45.6		$	43.5		$	45.6		$	43.5
Specific loan loss allowance	$	24.6		$	26.5		$	24.6		$	26.5
General loan loss allowance		21.0			17.0			21.0			17.0
Total commercial mortgage loan loss allowance	$	45.6		$	43.5		$	45.6		$	43.5

The larger commercial mortgage loan loss allowance as of June 30, 2012 compared to June 30, 2011 was primarily due to the net increase in the general reserve during the second quarter and first six months of 2012. The lower provision and charge-offs for the second quarter and first six months of 2012 compared to the same periods of 2011 were primarily related to lower losses associated with foreclosures, accepted deeds in lieu of foreclosure on commercial mortgage loans and other related charges associated with commercial mortgage loans leaving the portfolio during the second quarter and first six months of 2012.

The Company assesses the credit quality of its commercial mortgage loan portfolio quarterly by reviewing the performance of its portfolio which includes evaluating its performing and nonperforming commercial mortgage loans. Nonperforming commercial mortgage loans include all commercial mortgage loans that are 60 days or more past due and commercial mortgage loans that are not 60 days past due but are not substantially performing to other original contractual terms.

The decrease in impaired commercial mortgage loans at June 30, 2012 compared to December 31, 2011 was primarily due to more loans in this category being paid off or being foreclosed on during the first six months of 2012. As of June 30, 2012 and December 31, 2011, the Company did not have any commercial mortgage loans greater than 90 days delinquent that were accruing interest.

A restructuring is considered to be a troubled debt restructuring when the debtor is experiencing financial difficulties and the restructured terms constitute a concession. The Company evaluates all restructured commercial mortgage loans for indications of

27

troubled debt restructurings and the potential losses related to these restructurings. If a loan is considered a troubled debt restructuring, the Company impairs the loan and records a specific allowance for estimated losses. In some cases, the recorded investment in the loan may increase post-restructuring. As a result of adopting the amendments in ASU No. 2011-02, A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring, the Company assessed all restructurings that occurred during the period for identification as troubled debt restructurings. The Company did not identify any troubled debt restructurings that were not already considered impaired.

The following table sets forth information related to the troubled debt restructurings of financing receivables:

Interest Income

The Company records interest income in net investment income and continues to recognize interest income on delinquent commercial mortgage loans until the loans are more than 90 days delinquent. Interest income and accrued interest receivable are reversed when a loan is put on non-accrual status. For loans that are less than 90 days delinquent, management may reverse interest income and the accrued interest receivable if there is a question on the collectability of the interest. Interest income on loans in the 90-day delinquent category is recognized in the period the cash is collected. The Company resumes the recognition of interest income when the loan becomes less than 90 days delinquent and management determines it is probable that the loan will remain performing.

The amount of interest income recognized on impaired commercial mortgage loans was $1.0 million and $0.9 million for the second quarters of 2012 and 2011, respectively and was $2.1 million for the first six months of 2012 and 2011. The cash received by the Company in payment of interest on impaired commercial mortgage loans was $0.9 million and $0.7 million for the second quarters of 2012 and 2011, respectively and was $2.0 million and $1.4 million for the first six months of 2012 and 2011, respectively.

The Company closely monitors all past due commercial mortgage loans; additional attention is given to those loans at least 60 days past due. Commercial mortgage loans that were at least 60 days past due totaled $15.8 million and $17.1 million at June 30, 2012 and December 31, 2011, respectively. The Company’s current level of 60 days past due commercial mortgage loans is higher than its historical levels due to the current economic challenges. Overall, loans at least 60 days past due were 0.31% and 0.34% of the commercial mortgage loan portfolio at June 30, 2012 and December 31, 2011.

8. DERIVATIVE FINANCIAL INSTRUMENTS

The Company sells indexed annuities, which permit the holder to elect a fixed 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 and minimum guarantees. 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. The Company estimates the fair value of the index-based interest 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. The liability represents an estimate of the cost of the options to be purchased in the future to manage the risk related to the index-based interest guarantees. The liability for index-based interest guarantees is the present value of future cash flows attributable to the projected index growth that is in excess of cash flows attributable to fixed interest rates guarantees. The excess cash flows are discounted back to the date of the balance sheet using current market indicators for future interest rates and option costs. Cash flows depend on actuarial estimates for policyholder lapse behavior and management’s discretion in setting renewal index-based interest guarantees.

30

The Company purchases S&P 500 Index options for its interest crediting strategy used in its indexed annuity product. The S&P 500 Index options are purchased from investment banks and are selected in a manner that supports the amount of interest that is expected to be credited in the current year to annuity policyholder accounts that are dependent on the performance of the S&P 500 Index. The purchase of S&P 500 Index options is a pivotal part of the Company’s risk management strategy for indexed annuity products. The S&P 500 Index options are exclusively used for risk management. While valuations of the S&P 500 Index options are sensitive to a number of variables, valuations for S&P 500 Index options purchased are most sensitive to changes in the S&P 500 Index value and the implied volatilities of this index. The Company generally purchases one S&P 500 Index option contract per month, which has an expiry date of one year from the date of purchase.

The notional amount of the Company’s S&P 500 index options at June 30, 2012 and December 31, 2011 was $307.8 million and $303.1 million, respectively. Option premiums paid for the Company’s index option contracts were $2.8 million and $2.4 million for the second quarters of 2012 and 2011, respectively, and were $4.8 million and $4.7 million for the first six months of 2012 and 2011, respectively. The Company received $2.4 million and $4.6 million for options exercised for the second quarters of 2012 and 2011, respectively, and $4.0 million and $9.0 million for the first six months of 2012 and 2011, respectively.

The Company recognizes all derivative investments as assets or liabilities on the balance sheet at fair value. The Company does not designate its derivatives as hedging instruments and thus does not use hedge accounting. As such, any change in the fair value of the derivative assets and derivative liabilities is recognized as income or loss in the period of change. See “Note 6—Fair Value” for additional information regarding the fair value of the Company’s derivative assets and liabilities.

The following table sets forth the fair value of the Company’s derivative assets and liabilities:

Net (loss) gain	$	(0.6	)	$	0.7		$	(0.3	)	$	1.7

Changes in the fair value of the S&P 500 Index options and index-based interest guarantees are primarily the result of fluctuations in the S&P 500 Index and are recorded to net investment income and interest credited, respectively. Interest credited for the second quarter of 2012 was impacted by the Company’s annual update of the key assumptions used to value index-based interest guarantees, a process known as “unlocking.” The interest credited amount included negative interest related to the ‘unlocking’ process of $1.1 million and $1.5 million for the second quarters of 2012 and 2011, respectively, and $1.1 million and $1.5 million for first six months of 2012 and 2011, respectively.

The Company does not bear derivative-related risk that would require it to post collateral with another institution, and its index option contracts do not contain counterparty credit-risk-related contingent features. The Company is exposed to the credit worthiness of the institutions from which it purchases its S&P 500 Index options and these institutions’ continued abilities to perform according to the terms of the contracts. The current values for the credit exposure have been affected by fluctuations in the S&P 500 Index. The Company’s maximum credit exposure would require an increase of approximately 8.9% in the value of the S&P 500 Index. The maximum credit risk is calculated using the cap strike price of the Company’s S&P 500 Index options less the floor price, multiplied by the notional amount of the S&P 500 Index options.

9. DEFERRED ACQUISITION COSTS (“DAC”), VALUE OF BUSINESS ACQUIRED (“VOBA”) AND OTHER INTANGIBLE ASSETS

DAC, VOBA and other acquisition related 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 other intangible assets are subject to impairment tests on an annual basis or more frequently if circumstances indicate that carrying values may not be recoverable.

In October 2010, the FASB issued Accounting Standards Update (‘ASU’) No. 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts. ASU No. 2010-26 amends the codification guidance for insurance entities to eliminate the diversity of accounting treatment related to deferred acquisition costs. The Company adopted this standard retrospectively as of January 1, 2012, and comparative financial statements of prior periods have been adjusted.

The following table sets forth activity for DAC, VOBA and other intangible assets:

	Six Months Ended June 30, 2012			Year Ended December 31, 2011
	(In millions)

Total carrying value at end of period	$	350.4		$	344.9

The Company defers certain acquisition costs that vary with and are directly related to the origination of 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. Changes in actual persistency are reflected in the calculated DAC balance. Costs that are not directly associated with the acquisition of new business are not deferred as DAC and are charged to expense as incurred. Generally, annual commissions are considered expenses and are not deferred.

32

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. The Company amortizes 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.

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. For the Company’s individual deferred annuities, DAC is generally amortized over 30 years, though expected gross profits can fluctuate due to changes in the fair value of our S&P 500 Index options and index-based interest guarantees. DAC for group annuity products is amortized over 10 years.

VOBA primarily represents the discounted future profits of business assumed through reinsurance agreements. The Company has established VOBA for a block of individual disability business assumed from 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, 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 the Company’s assumptions, the Company could be required to make adjustments to VOBA and related amortization. During the first six months of 2012, the Company recorded an $0.8 million impairment to VOBA due to experience related to the block of claims assumed from TIAA. The Company did not record a similar impairment in the second quarter of 2012, or in the second quarter and first six months of 2011. The VOBA associated with the TIAA transaction is amortized in proportion to expected gross profits with an amortization period of up to 20 years. For the VOBA associated with the Minnesota Life block of business assumed, the amortization period is up to 30 years and is amortized in proportion to future premiums. The accumulated amortization of VOBA was $64.5 million and $62.4 million at June 30, 2012 and December 31, 2011, respectively.

The following table sets forth the amount of DAC and VOBA balances amortized in proportion to expected gross profits and the percentage of the total balance of DAC and VOBA amortized in proportion to expected gross profits:

	June 30, 2012					December 31, 2011
	Amount		Percent			Amount		Percent
	(Dollars in millions)
DAC	$	64.4		22.6	%	$	60.7		22.1	%
VOBA		6.1		25.1			7.1		26.9

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

• Persistency.

• Interest rates, which affect both investment income and interest credited.

• Stock market performance.

• Capital gains and losses.

• Claim termination rates.

• Amount of business in force.

These assumptions are modified to reflect actual experience when appropriate. Although a change in a single assumption may have an impact on the calculated amortization of DAC or VOBA for balances associated with investment contracts, 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 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 generally occurs as a result of actual experience or future expectations differing from previous estimates. As a result of unlocking, the amortization schedule for future periods is also adjusted.

33

The following table sets forth the impact of unlocking on DAC and VOBA balances:

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2011		2012		2011
	(In millions)
Decrease to DAC and VOBA	$	0.3	$	0.6	$	1.1	$	0.6

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. However, future changes in DAC and VOBA balances due to changes in underlying assumptions are not expected to be material.

The Company’s other intangible assets are subject to amortization and consist of certain customer lists from Asset Management business acquired and an individual disability marketing agreement. Customer lists have a combined estimated weighted-average remaining life of approximately 8.4 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 Minnesota Life marketing agreement will be fully amortized by the end of 2023. The accumulated amortization of other intangible assets was $33.6 million and $30.6 million at June 30, 2012 and December 31, 2011, respectively.

The following table sets forth the estimated net amortization of VOBA and other intangible assets for the remainder of 2012 and for each of the next five years:

10.  COMMITMENTS AND CONTINGENCIES

Litigation Contingencies

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 June 30, 2012. 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.

Senior Unsecured Revolving Credit Facility (“Facility”) Contingencies

On June 22, 2012, StanCorp entered into an agreement for a four-year, $250 million Facility. Additionally, upon the request of StanCorp and with consent of the lenders under the Facility, the Facility can be increased to $350 million. The termination date of the Facility is June 22, 2016, though, at the option of StanCorp and with the consent of the lenders under the Facility, the termination date can be extended for two additional one year periods. Borrowings from the facility will be used to provide for the 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 two financial covenants that are based on the Company’s ratio of total debt to total capitalization and consolidated net worth. StanCorp is also subject to covenants that limit subsidiary indebtedness. The Facility is subject to performance pricing based upon the Company’s publicly announced debt ratings and includes an interest rate option at the election of the borrower of a base rate plus the applicable margin or the LIBOR rate plus the applicable margin, plus facility and utilization fees. At June 30, 2012, StanCorp was in compliance with all financial covenants under the Facility and had no outstanding balance on the Facility.

Effective upon the closing of the Facility, a prior credit agreement was terminated. This prior credit agreement was scheduled to terminate June 15, 2013.

Other Financing Obligations

The Company has $250 million of 6.875%, 10-year senior notes (“2012 Senior Notes”), which mature on October 1, 2012. The principal amount of the 2012 Senior Notes is payable at maturity and interest is payable semi-annually in April and October. Given the maturity date of the 2012 Senior Notes, they have been classified as short-term debt as of June 30, 2012. See “Note 13 Subsequent Events” for further discussion.

The Company has $300 million of 6.90%, junior subordinated debentures (“Subordinated Debt”), which matures on June 1, 2067, is non-callable at par for the first 10 years (prior to June 1, 2017). The principal amount of the Subordinated Debt is payable at final maturity. Interest is payable semi-annually in June and December for the first 10 years up to June 1, 2017, 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. The

34

declaration and payment of dividends to shareholders would be restricted if the Company elected to defer interest payments on its Subordinated Debt. If elected, the restriction would be in place during the interest deferral period. StanCorp is currently not deferring interest on the Subordinated Debt.

In the normal course of business, the Company commits to fund commercial mortgage loans generally up to 90 days in advance. At June 30, 2012, the Company had outstanding commitments to fund commercial mortgage loans totaling $161.9 million, with fixed interest rates ranging from 4.375% to 5.750%. 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, the Company will retain the commitment fee and good faith deposit. Alternatively, if the Company terminates 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.

11.  ACCOUNTING PRONOUNCEMENTS

ASU 2011-11, Disclosures about Offsetting Assets and Liabilities

In December 2011, the FASB issued ASU No. 2011-11, Disclosures about Offsetting Assets and Liabilities. The main objective of ASU No. 2011-11 is to enhance disclosures for financial instruments and derivative instruments which have right of setoff conditions. Under the guidance provided in this ASU, entities would be required to disclose the amounts offset in determining the net amounts presented in their statement of financial position. The amount of both the recognized asset and the recognized liability subject to offset under the same arrangement will become a required disclosure.

ASU No. 2011-11 is effective for interim and annual periods beginning on or after January 1, 2013. The Company does not currently have exposure to hedges, derivatives or master netting arrangements that would be subjected to these additional disclosures. Therefore, the Company does not expect this ASU to have a material effect on its asset and liability disclosures in the financial statements.

12. INCOME TAXES

Income taxes may differ from the amount computed by applying the Federal corporate tax rate of 35% to pre-tax income because of the net results of permanent differences between book and taxable income and because of the inclusion of state and local income taxes, net of the federal tax benefit.

The following table sets forth the combined federal and state effective income tax rates:

	Three Months Ended June 30,						Six Months Ended June 30,
	2012			2011			2012			2011
Combined federal and state effective income tax rates		11.5	%		27.6	%		21.5	%		30.9	%

During the first six months of 2012, and throughout 2011, the Company purchased tax-advantaged investments, contributing to a decrease in the effective tax rate. In addition, the effective tax rate was also reduced by favorable book-to-tax differences relative to a lower level of income in 2012. These investments, along with lower pre-tax net income, were the primary drivers of the decreases in the effective tax rate for the second quarter and first six months of 2012 when compared to the same periods for 2011.

13. SUBSEQUENT EVENTS

On August 3, 2012, the Company priced a public offering of $250 million of senior notes (“2022 Senior Notes”) which will have a final maturity of August 15, 2022. The 2022 Senior Notes will bear an annual interest rate of 5.00%. Interest will be paid semi-annually on February 15 and August 15, beginning on February 15, 2013. The Company intends to use the net proceeds, together with cash on hand, to repay its $250 million of 6.875% 10-year 2012 Senior Notes due October 1, 2012. The Company intends to close this public offering on August 10, 2012.

ITEM 2: MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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 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 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 2011 Form 10-K and our current report on Form 8-K dated July 18, 2012 which updated certain items in our annual report on Form 10-K for the retrospective adoption of Accounting Standards Update (“ASU”) No. 2012-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts. 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 disclosures of 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 our performance. See “Critical Accounting Policies and Estimates.”

Financial measures that exclude after-tax net capital gains and losses are non-GAAP measures. To provide investors with a broader understanding of earnings, we provide net income per diluted share excluding after-tax net capital gains and losses, along with the GAAP measure of net income per diluted share, because capital gains and losses are not likely to occur in a stable pattern.

We have made in this Form 10-Q, and from time to time may make in our public filings, news releases and oral presentations and discussions, certain statements, which are predictive in nature and not based on historical facts. 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

The following table sets forth selected consolidated financial results:

	Three Months Ended June  30,						Six Months Ended June  30,
	2012			2011			2012			2011
	(Dollars in millions except share data)
Net income	$	20.0		$	17.8		$	55.2		$	51.1
After-tax net capital losses		(2.5	)		(8.5	)		(2.6	)		(10.0	)
Net income excluding after-tax net capital losses	$	22.5		$	26.3		$	57.8		$	61.1
Diluted earnings per common share:
Net income	$	0.45		$	0.40		$	1.24		$	1.12
After-tax net capital losses		(0.06	)		(0.19	)		(0.06	)		(0.22	)
Net income excluding after-tax net capital losses	$	0.51		$	0.59		$	1.30		$	1.34
Diluted weighted-average common shares outstanding		44,354,720			45,056,472			44,407,325			45,619,277

Consolidated financial results for the second quarter and first six months of 2012 compared to the same periods of 2011 reflected a comparatively higher benefit ratio in our Insurance Services segment, primarily due to less favorable claims experience in our group long term disability business. The effect of the less favorable claims experience in the group long term disability business was partially offset by more favorable claims experience in our individual disability business and a lower effective income tax rate. Diluted earnings per share for the three and six months ended June 30, 2012 reflected the effect of a decrease in diluted weighted-average common shares outstanding, which was primarily due to share repurchases.

Outlook

We manage for long-term profitability by focusing on business diversification, disciplined product pricing, sound underwriting, effective claims management and high-quality customer service. We will address challenges that arise with financial discipline.

Our earnings for the second quarter and first six months of 2012 were below our expectations, which reflected an increased level of claims severity, continued elevated claims incidence and the effect of low interest rates in our group long term disability business. As a result of our recent experience surrounding claims severity and claims incidence, we have continued to make adjustments to our pricing and ensuring appropriate claims management resources in response to the current environment.

36

Based on the results for the first six months of 2012, we expect that the 2012 annual benefit ratio for the group insurance business will exceed the guidance range of 80% to 82% that we provided earlier this year. We expect the benefit ratio to remain elevated while economic conditions improve and the effects of our pricing actions take hold. As a result, we expect to be below our 2012 guidance range of $3.60 to $3.90 for net income per diluted share, excluding after-tax net capital gains and losses, and below the guidance range of 9% to 10% for return on average equity, excluding after-tax net capital gains and losses from net income and accumulated other comprehensive income (“AOCI”) from equity. Additionally, we expect our effective income tax rate for 2012 will be below our guidance range of 26% to 27%.

We remain focused on continuing to provide excellent products and services to our customers, enhancing our financial strength and increasing value to our shareholders. We will continue to focus on optimizing shareholder value through sustainable profitability by investing in new product and service capabilities and through the strategic use of capital, as we believe these actions position us well for growth as the economy recovers.

Primary Drivers of 2012 Results

The primary drivers of our results continue to be the group insurance benefit ratio and group insurance premium growth. Our group insurance benefit ratio for the first six months of 2012 was 86.0% and was outside our annual expected range of 80.0% to 82.0%. During the first six months of 2012, the group insurance benefit ratio was affected by comparatively higher claims severity and continued high claims incidence. Claims experience can fluctuate widely from quarter to quarter and tends to be more stable when measured over a longer period of time. The benefit ratio is primarily affected by reserves established based on growth of our in force block of business, claims experience and assumptions used to establish related reserves, such as our discount rate.

The interest rate environment and its effect on our discount rate is a major driver in our reserve levels. The discount rate used in the second quarter of 2012 for newly established long term disability claim reserves was 4.00%, compared to 5.25% used for the second quarter of 2011 and 4.75% used for the first quarter of 2012. A 25 basis point increase or decrease in the discount rate results in a comparable increase or decrease in quarterly pre-tax income of approximately $1.8 million. The decrease in the discount rate from the second quarter of 2011 and the first quarter of 2012 was primarily the result of a continued low interest rate environment. We will maintain our disciplined approach to interest rate management given the uncertainty of the future interest rate environment and the corresponding impact on new investment yields and the discount rates used to establish claim reserves.

Our Insurance Services segment premiums increased 2.0% to $546.5 million and 3.0% to $1.10 billion for the second quarter and first six months of 2012 compared to the same periods of 2011, respectively, primarily due to the favorable impact of experience rated refunds. Premium growth continues to be affected by the economic environment, which has caused lower wage rate and job growth for our group insurance customers.

Consolidated Results of Operations

Revenues

Revenues consist of premiums, administrative fees, net investment income and net capital gains and losses. Historically, premium growth in our Insurance Services segment and administrative fee revenue growth in our Asset Management segment have been the primary drivers of consolidated revenue growth.

The following table sets forth consolidated revenues:

	Three Months Ended June 30,									Six Months Ended June 30,
	2012			2011			Percent    Change			2012			2011			Percent    Change
	(Dollars in millions)
Revenues:
Premiums	$	548.1		$	537.0			2.1	%	$	1,101.4		$	1,070.8			2.9	%
Administrative fees		29.8			29.5			1.0			58.4			58.9			(0.8	)
Net investment income		151.4			152.6			(0.8	)		311.1			309.6			0.5
Net capital losses		(4.0	)		(13.1	)		(69.5	)		(4.2	)		(15.6	)		(73.1	)
Total revenues	$	725.3		$	706.0			2.7		$	1,466.7		$	1,423.7			3.0

The increase in consolidated revenues for the second quarter and first six months of 2012 compared to the same periods of 2011 was primarily due to an increase in premiums from our Insurance Services segment and a decrease in net capital losses. Net capital gains and losses are reflected in the Other category. See “Business Segments—Other—Net Capital Gains (Losses).”

Premiums

Insurance Services segment premiums are the primary driver of consolidated premiums and are affected by the following factors:

• Sales.

37

• Customer retention.

• Organic growth in our group insurance businesses, which is derived from existing policyholders’ employment and wage growth.

• Experience rated refunds (“ERRs”), which represent cost sharing arrangements with certain group contract holders that provide refunds to the contract holders when claims experience is more favorable than contractual benchmarks, and provide for additional premiums to be paid when claims experience is less favorable than contractual benchmarks. ERRs can fluctuate widely from quarter to quarter depending on the underlying experience of specific contracts.

The following table sets forth premiums by segment:

	Three Months Ended June 30,							Six Months Ended June 30,
	2012		2011		Percent    Change			2012		2011		Percent    Change
	(Dollars in millions)
Premiums:
Insurance Services	$	546.5	$	535.6		2.0	%	$	1,097.6	$	1,066.1		3.0	%
Asset Management		1.6		1.4		14.3			3.8		4.7		(19.1	)
Total premiums	$	548.1	$	537.0		2.1		$	1,101.4	$	1,070.8		2.9

The increase in premiums from our Insurance Services segment for the second quarter and first six months of 2012 compared to the same periods of 2011 was primarily driven by ERR activity. ERRs for the second quarter and first six months of 2012 increased premiums by $7.1 million, and $11.2 million, respectively, while ERRs for the second quarter and first six months of 2011 decreased premiums by $5.7 million and $10.2 million, respectively. See “Business Segments—Insurance Services Segment.”

Premiums from our Asset Management segment are generated from sales of life-contingent annuities, which are a single-premium product. Due to the competitive nature of single-premium products, premiums in the Asset Management segment can fluctuate widely from quarter to quarter. See “Business Segments—Asset Management Segment.”

Administrative Fee Revenues

The primary driver for administrative fee revenues is the level of assets under administration in our Asset Management segment, which is primarily driven by equity market performance and net customer deposits. Administrative fee revenues from our Insurance Services segment are primarily derived from insurance products for which we provide only administrative services and absence management services.

The following table sets forth administrative fee revenues by segment:

	Three Months Ended June 30,									Six Months Ended June 30,
	2012			2011			Percent    Change			2012			2011			Percent    Change
	(Dollars in millions)
Administrative fee revenues:
Insurance Services	$	4.2		$	2.9			44.8	%	$	7.3		$	5.6			30.4	%
Asset Management		30.0			30.9			(2.9	)		59.9			61.5			(2.6	)
Other		(4.4	)		(4.3	)		(2.3	)		(8.8	)		(8.2	)		(7.3	)
Total administrative fee revenues	$	29.8		$	29.5			1.0		$	58.4		$	58.9			(0.8	)

The decrease in administrative fee revenues in our Asset Management segment for the second quarter and first six months of 2012 compared to the same periods of 2011 was primarily due to a decrease in our assets under administration in our retirement plan trust assets and private client wealth management assets. See “Business Segments—Asset Management Segment.”

The increase in administrative fee revenues in our Insurance Services segment for the second quarter and first six months of 2012 compared to the same periods of 2011 was primarily due to an increase in administrative and absence management service fees.

Net Investment Income

Net investment income is affected by changes in levels of invested assets, interest rates, fluctuations in the fair value of our Standard & Poor’s (“S&P”) 500 Index call spread options (“S&P 500 Index options”) related to our indexed annuity product, commercial mortgage loan prepayment fees and bond call premiums.

38

The following table sets forth net investment income by segment and associated key indicators:

	Three Months Ended June 30,								Six Months Ended June 30,
	2012			2011		Change			2012		2011		Change
	(Dollars in millions)
Net investment income:
Insurance Services	$	83.6		$	85.4		(2.1	)%	$	168.2	$	169.8		(0.9	)%
Asset Management		64.6			64.9		(0.5	)		137.7		134.5		2.4
Other		3.2			2.3		39.1			5.2		5.3		(1.9	)
Total net investment income	$	151.4		$	152.6		(0.8	)	$	311.1	$	309.6		0.5
Key indicators of net investment income:
Contribution from the change in fair value of the S&P 500 Index options	$	(2.3	)	$	0.8	$	(3.1	)	$	4.4	$	3.8	$	0.6
Average invested assets		12,243.7			11,417.8		7.2	%		12,129.9		11,348.7		6.9	%

	At June 30,
	2012			2011
Portfolio yields:
Fixed maturity securities		4.89	%		5.19	%
Commercial mortgage loans		6.24			6.41

The decrease in net investment income for the second quarter of 2012 compared to the second quarter of 2011 was primarily due to a decline in the portfolio yields for fixed maturity securities and commercial mortgage loans and a change in fair value of our S&P 500 Index options due to the currently low interest rate environment. These decreases were partially offset by an increase in average invested assets.

The increase in net investment income for first six months of 2012 compared to the first six months of 2011 was primarily due to an increase in average invested assets. Partially offsetting this increase was a decline in the portfolio yields for fixed maturity securities and commercial mortgage loans and a $4.3 million decrease in call premiums received on certain bond holdings as fewer issuers exercised make-whole provisions to retire outstanding debt. Also partially offsetting the increased net investment income was a $2.7 million increase in anticipated operating losses related to our low income housing tax credit investments. The benefits from these investments are recorded as a credit to income taxes while the anticipated operating losses are recorded in net investment income.

We may experience lower new money interest rates in the future if credit spreads tighten and interest rates decline. New money interest rates are also affected by the current volume and mix of commercial mortgage loan originations, the purchases of fixed maturity securities, tax-advantaged investments and other investments.

We seek investments containing call or prepayment protection to ensure our expected cash flow is not adversely affected by unexpected prepayments. Callable bonds without make-whole provisions represented 7.6% of our fixed maturity security portfolio at June 30, 2012. We also originate commercial mortgage loans containing a make-whole prepayment provision requiring the borrower to pay a prepayment fee. As interest rates decrease, potential prepayment fees increase. These larger prepayment fees deter borrowers from refinancing during a low interest rate environment. Approximately 95% of our commercial mortgage loan portfolio contains a prepayment provision. Commercial mortgage loans without a make-whole prepayment provision generally contain fixed percentage prepayment fees that mitigate prepayments but may not fully protect our expected cash flows in the event of prepayment. Commercial mortgage loan prepayment fees were $1.8 million and $1.3 million for the second quarters of 2012 and 2011, respectively, and $3.0 million and $2.3 million for the first six months of 2012 and 2011, respectively. The increases in commercial mortgage loan prepayment fees were primarily the result of a continued low interest rate environment.

Net Capital Gains (Losses)

Net capital gains and losses are reported in the Other category and are not likely to occur in a stable pattern. Net capital gains and losses primarily occur as a result of sales of our assets for more or less than carrying value, other-than-temporary impairments (“OTTI”) of assets in our bond portfolio, provisions to our commercial mortgage loan loss allowance, losses recognized due to impairment of real estate and impairments of low-income housing tax credit investments.

39

The following table sets forth net capital gains and losses and associated key components:

	Three Months Ended June 30,									Six Months Ended June 30,
	2012			2011			Dollar     Change			2012			2011			Dollar     Change
	(In millions)
Net capital losses	$	(4.0	)	$	(13.1	)	$	9.1		$	(4.2	)	$	(15.6	)	$	11.4
Key components of net capital gains (losses):
Fixed maturity securities	$	1.0		$	3.0		$	(2.0	)	$	2.2		$	6.5		$	(4.3	)
Real estate investments		—			3.2			(3.2	)		—			8.5			(8.5	)
Real estate owned		(0.3	)		(10.3	)		10.0			(0.7	)		(12.8	)		12.1
Provision to our commercial mortgage loan loss allowance		(5.1	)		(9.3	)		4.2			(6.4	)		(18.0	)		11.6

Net capital losses for the second quarter of 2012 and the first six months of 2012 were primarily related to our commercial mortgage loan loss allowance provision and losses recognized on real estate acquired in satisfaction of debt through foreclosure or the acceptance of deeds in lieu of foreclosure on commercial mortgage loans (“real estate owned”). These losses were partially offset by net capital gains related to the sale of certain fixed maturity securities. See “Liquidity and Capital Resources—Investing Cash Flows—Commercial Mortgage Loans” and “Business Segments—Other—Net Capital Gains (Losses).”

Benefits and Expenses

Benefits to Policyholders

Consolidated benefits to policyholders is primarily affected by the following factors:

• Reserves that are established in part based on premium levels.

• Claims experience—the predominant factors affecting claims experience are claims incidence, measured by the number of claims, and claims severity, measured by the magnitude of the claim and the length of time a disability claim is paid.

• Reserve assumptions—the assumptions used to establish the related reserves reflect expected incidence and severity, and the discount rate. The discount rate is affected by new money investment interest rates and the overall portfolio yield. See “Critical Accounting Policies and Estimates—Reserves for Future Policy Benefits and Claims.”

• Current estimates for future benefits on life-contingent annuities.

40

The following table sets forth benefits to policyholders by segment:

	Three Months Ended June 30,							Six Months Ended June 30,
	2012		2011		Percent    Change			2012		2011		Percent    Change
	(Dollars in millions)
Benefits to policyholders:
Insurance Services	$	471.0	$	448.1		5.1	%	$	915.7	$	882.4		3.8	%
Asset Management		4.9		4.3		14.0			10.2		10.1		1.0
Total benefits to policyholders	$	475.9	$	452.4		5.2		$	925.9	$	892.5		3.7

The increases in benefits to policyholders for the second quarter and first six months of 2012 compared to the same periods of 2011 were primarily due to an increased level of claims severity and continued high claims incidence in our group long term disability business. In addition, the discount rate used for newly established long term disability claim reserves decreased 125 basis points to 4.00% for the second quarter of 2012, compared to 5.25% for the second quarter of 2011 resulting in a corresponding increase in benefits to policyholders of approximately $9 million. See “Business Segments—Insurance Services Segment—Benefits and Expenses—Benefits to Policyholders (including interest credited).”

Interest Credited

Interest credited represents interest paid to policyholders on retirement plan general account assets, individual fixed-rate annuity deposits and index-based interest guarantees embedded in indexed annuities (“index-based interest guarantees”) in the Asset Management segment and interest paid on life insurance proceeds on deposit in the Insurance Services segment.

Interest credited is primarily affected by the following factors:

• Growth in general account assets under management.

• Growth in individual fixed-rate annuity liabilities.

• Changes in new investment interest rates and overall portfolio yield, which influence our interest-crediting rate for our customers.

• Changes in customer retention.

• Changes in the fair value of the index-based interest guarantees. These changes may fluctuate from quarter to quarter due to changes in interest rates and equity market volatility. See “Business Segments—Asset Management Segment—Benefits and Expenses—Interest Credited” for information regarding the interest credited on our indexed annuity product.

The following table sets forth interest credited and associated key components for the periods presented:

Contribution from the change in fair value of index-based interest guarantees	$	(1.7	)	$	0.1	$	(1.8	)	$	4.7	$	2.1	$	2.6
Average individual annuity assets under administration		3,064.5			2,822.9		8.6	%		3,046.2		2,789.7		9.2	%

The decrease in interest credited for the second quarter of 2012 compared to the second quarter of 2011 was primarily due to the change in fair value of our index-based interest guarantees. The increase in interest credited for the first six months of 2012 compared to first six months of 2011 was primarily due to an increase in our average individual fixed-rate annuity assets under administration and the change in fair value of our index-based interest guarantees.

Operating Expenses

The following table sets forth operating expenses:

	Three Months Ended June 30,							Six Months Ended June 30,
	2012		2011		Percent    Change			2012		2011		Percent    Change
	(Dollars in millions)
Operating expenses	$	116.7	$	118.1		(1.2	)%	$	240.6	$	236.4		1.8	%

The decrease in operating expenses for the second quarter of 2012 compared to the second quarter of 2011 was primarily due to reduced costs associated with information technology operations initiatives implemented in 2011.

The increase in operating expenses for the first six months of 2012 compared to the first six months of 2011 was primarily related to business growth and information technology project costs. 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 other factors such as customer retention, sales, growth in assets under administration and the profitability of business in each of our segments.

The following table sets forth commissions and bonuses:

	Three Months Ended June 30,							Six Months Ended June 30,
	2012		2011		Percent    Change			2012		2011		Percent    Change
	(Dollars in millions)
Commissions and bonuses	$	51.3	$	54.2		(5.4	)%	$	106.7	$	113.0		(5.6	)%

The decreases in commissions and bonuses for the second quarter and first six months of 2012 compared to the same periods of 2011 was primarily due to lower group insurance and individual annuity business sales.

Net Change in Deferred Acquisition Costs (“DAC”), Value of Business Acquired (“VOBA”) and Other Intangible Assets

We normally defer certain acquisition costs that vary and are directly related to the origination of 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. 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 and 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. Our other intangible assets, consisting of customer lists and marketing agreements, are also subject to amortization. Customer lists were obtained through acquisitions of Asset Management businesses and have a combined estimated weighted-average remaining life of approximately 8.4 years. The intangible asset associated with the individual disability marketing agreement with the Minnesota Life Insurance Company (“Minnesota Life”) will be fully amortized by 2023. See “Critical Accounting Policies and Estimates—DAC, VOBA and Other Intangible Assets.”

The following table sets forth the operating impact resulting in a net decrease (increase) in DAC, VOBA and other intangible assets:

	Three Months Ended June 30,								Six Months Ended June 30,
	2012			2011			Dollar    Change		2012			2011			Dollar    Change
	(In millions)
Deferral of acquisition costs	$	(16.9	)	$	(18.6	)	$	1.7	$	(38.4	)	$	(44.4	)	$	6.0
Amortization of DAC, VOBA and other intangible assets		17.2			16.6			0.6		36.2			34.0			2.2
Net decrease (increase) in DAC, VOBA and other intangible assets	$	0.3		$	(2.0	)	$	2.3	$	(2.2	)	$	(10.4	)	$	8.2

The net decrease (increase) in DAC, VOBA and other intangible assets was higher for the second quarter and first six months of 2012 compared to the same periods of 2011, and was primarily due to an increase in the amortization of DAC, in addition to a decrease in deferrals in our Insurance Services segment resulting from lower group insurance sales.

Income Taxes

Income taxes may differ from the amount computed by applying the federal corporate tax rate of 35% to pre-tax income because of the net result of permanent differences between book and taxable income and because of the inclusion of state and local income taxes, net of the federal tax benefit.

The following table sets forth the combined federal and state effective income tax rates:

	Three Months Ended June  30,						Six Months Ended June  30,
	2012			2011			2012			2011
Combined federal and state effective income tax rates		11.5	%		27.6	%		21.5	%		30.9	%

During the first six months of 2012, and throughout 2011, we purchased tax-advantaged investments, contributing to a decrease in our effective tax rate. In addition the effective tax rate was also reduced by favorable book-to-tax differences relative to a lower level of income in 2012. These investments, along with lower pre-tax net income, were the primary drivers of the decreases in our effective tax rate for the second quarter and first six months of 2012 when compared to the same periods for 2011.

Business Segments

We operate through two reportable segments: Insurance Services and Asset Management, as well as an Other category. 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, group dental and group vision insurance, and absence management services. The Asset Management segment offers full-service 401(k) plans, 403(b) plans, 457 plans, defined benefit plans, money purchase pension plans, profit sharing plans and non-qualified deferred compensation products and services. The Asset Management segment also offers investment advisory and management services, financial planning services, commercial mortgage loan origination and servicing, individual fixed-rate annuity products, group annuity contracts and retirement plan trust products. The Other category includes return on capital not allocated to the product segments, holding company expenses, operations of certain unallocated subsidiaries, interest on debt, unallocated expenses, net capital gains and losses and adjustments made in consolidation.

The following table sets forth segment revenues measured as a percentage of total revenues, excluding revenues from the Other category:

	Three Months Ended June  30,						Six Months Ended June  30,
	2012			2011			2012			2011
Insurance Services		86.8	%		86.5	%		86.3	%		86.1	%
Asset Management		13.2			13.5			13.7			13.9

Insurance Services Segment

The Insurance Services segment is our largest segment and substantially influences our consolidated financial results.

The following table sets forth key indicators that we use to manage and assess the performance of the Insurance Services segment:

	Three Months Ended June 30,									Six Months Ended June 30,
	2012			2011			Percent  Change			2012			2011			Percent    Change
	(Dollars in millions)
Premiums	$	546.5		$	535.6			2.0	%	$	1,097.6		$	1,066.1			3.0	%
Total revenues		634.3			623.9			1.7			1,273.1			1,241.5			2.5
Income before income taxes		23.3			36.9			(36.9	)		69.4			82.9			(16.3	)
Sales (annualized new premiums) reported at contract effective date		26.7			42.8			(37.6	)		160.5			208.6			(23.1	)
Benefit ratios, including interest credited (% of premiums):
Insurance Services		86.4	%		84.0	%					83.7	%		83.0	%
Group insurance		88.5			84.8						86.0			84.5
Individual disability		60.8			74.5						56.4			65.9
Operating expense ratio (% of premiums)		15.8	%		16.0	%					16.3	%		16.2	%

Income before income taxes decreased for the second quarter and first six months of 2012 when compared to the same periods of 2011 primarily due to less favorable claims experience in our group long term disability insurance business, in addition to a 125 basis point decrease in the discount rate used to establish reserves on newly incurred group long term disability claims. These decreases to income were partially offset by premium growth in our group long term disability insurance business.

Revenues

Revenues for the Insurance Services segment are driven primarily by growth in Insurance Services premiums. The increase in revenues for the second quarter and first six months of 2012 compared to the same periods of 2011 was primarily due to higher premiums in our group insurance business primarily related to ERRs.

Premiums

The primary factors that affect premiums for the Insurance Services segment are sales and customer retention for our insurance products and organic growth in our group insurance businesses derived from existing group policyholders’ employment and wage growth. Premium levels can also be influenced by ERRs, which represent cost sharing arrangements with certain group contract holders that provide refunds to the contract holders when claims experience is more favorable than contractual benchmarks, and provide for additional premiums to be paid when claims experience is less favorable than contractual benchmarks. ERRs can fluctuate widely from quarter to quarter depending on the underlying experience of specific contracts.

The following table sets forth premiums and sales by line of business for the Insurance Services segment:

	Three Months Ended June 30,								Six Months Ended June 30,
	2012		2011			Dollar    Change			2012		2011			Dollar    Change
	(Dollars in millions)
Premiums:
Group life and AD&D	$	223.8	$	224.5		$	(0.7	)	$	448.7	$	446.1		$	2.6
Group long term disability		200.2		201.4			(1.2	)		404.4		401.5			2.9
Group short term disability		54.0		52.5			1.5			107.8		103.9			3.9
Group other		19.6		20.2			(0.6	)		39.5		40.0			(0.5	)
Experience rated refunds		7.1		(5.7	)		12.8			11.2		(10.2	)		21.4
Total group insurance		504.7		492.9			11.8			1,011.6		981.3			30.3
Individual disability		41.8		42.7			(0.9	)		86.0		84.8			1.2
Total premiums	$	546.5	$	535.6			10.9		$	1,097.6	$	1,066.1			31.5
Key indicators of premiums:
Total premiums excluding ERRs	$	539.4	$	541.3		$	(1.9	)	$	1,086.4	$	1,076.3		$	10.1
Group insurance sales (annualized new premiums) reported at contract effective date		22.3		37.7			(15.4	)		151.1		198.0			(46.9	)
Individual disability sales (annualized new premiums)		4.4		5.1			(0.7	)		9.4		10.6			(1.2	)

The increase in group insurance premiums for the second quarter and first six months of 2012 compared to the same periods of 2011 was primarily driven by ERR activity. ERRs increased premiums by $7.1 million and $11.2 million for the second quarter and first six months of 2012, while ERRs decreased premiums by $5.7 million and $10.2 million for the same periods of 2011, respectively. Group insurance premiums for the second quarter of 2012 excluding the impact of ERRs decreased 0.2% compared to the second quarter of 2011 reflecting a decline in sales of our group insurance products and negative organic growth, partially offset by renewal premium rate increases. Group insurance premium growth for the first six months of 2012 excluding the impact of ERRs was 0.9% compared to the same period for 2011, due to a combination of strong 2011 sales and renewal premium rate increases, partially offset by negative organic growth and lower group insurance sales for the first six months of 2012 compared to the first six months of 2011.

Sales.    Sales of our group insurance products reported as annualized new premiums decreased for the first six months of 2012 compared to the first six months of 2011, primarily due to pricing competition.

Persistency.    Persistency is reported annually. Premium growth for the second quarter of 2012 reflected continued strong customer retention levels from 2011.

Organic Growth.    Premium growth in our group insurance in force business is affected by employment and wage growth in our existing customer base, changes in price per insured and the average age of employees. The economy has continued to negatively affect wage rate and employment levels in a significant portion of our customer base, and therefore has put negative pressure on our premiums.

We continue to make progress with the implementation of our pricing actions that began in 2011 related to higher claims incidence and the continued low interest rate environment. Our pricing reflects our long-term expectations of claims experience, demographic changes, return objectives and interest rates. As of the end of our January 2012 renewal season we have had the opportunity to re-price approximately one third of our long term disability business and we are getting favorable acceptance on our rate increases. By the end of the January 2013 renewal season we will have had the opportunity to re-price about three-fourths of our long term disability business. Our sales force is communicating and selling our unique value proposition, while the rest of our employees are delivering the quality service on which we have based our reputation in the employee benefits marketplace.

Net Investment Income

The following table sets forth net investment income for the Insurance Services segment:

	Three Months Ended June 30,							Six Months Ended June 30,
	2012		2011		Percent    Change			2012		2011		Percent    Change
	(Dollars in millions)
Net investment income	$	83.6	$	85.4		(2.1	)%	$	168.2	$	169.8		(0.9	)%

Net investment income is primarily affected by changes in levels of invested assets and interest rates. See “Consolidated Results of Operations—Revenues—Net Investment Income.”

Benefits and Expenses

Benefits to Policyholders (including interest credited)

Benefits to policyholders is primarily affected by the following factors:

• Reserves that are established in part based on premium levels.

• Claims experience – the predominant factors affecting claims experience are claims incidence, measured by the number of claims, and claims severity, measured by the magnitude of the claim and the length of time a disability claim is paid.

• Reserve assumptions – the assumptions used to establish the related reserves reflect claims incidence and severity, and the discount rate. The discount rate is affected by the new money investment interest rates and the overall portfolio yield. See “Critical Accounting Policies and Estimates—Reserves for Future Policy Benefits and Claims.”

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 growth in our in force block.

The following table sets forth benefits to policyholders (including interest credited) and the benefit ratios for the Insurance Services segment:

	Three Months Ended June 30,									Six Months Ended June 30,
	2012			2011			Percent    Change			2012			2011			Percent    Change
	(Dollars in millions)
Benefits to policyholders, including interest credited	$	472.0		$	449.7			5.0	%	$	918.3		$	885.0			3.8	%
Benefit ratios, including interest credited (% of premiums):
Insurance Services segment		86.4	%		84.0	%					83.7	%		83.0	%
Group insurance		88.5			84.8						86.0			84.5
Individual disability		60.8			74.5						56.4			65.9

The increase in Insurance Services benefits to policyholders (including interest credited) for the second quarter and first six months of 2012 compared to the same periods of 2011 was primarily due to an increased level of claims severity and continued elevated claims incidence in the group long term disability insurance business, and the 125 basis point decrease in the discount rate used for newly established long term disability claim reserves for the second quarter of 2012. The effect of the less favorable claims experience in the group long term disability business was partially offset by more favorable claims experience in our individual disability business.

The group insurance benefit ratio for the second quarter and first six months of 2012 was outside our estimated annual range for 2012 of 80% to 82%. We expect the benefit ratio to remain elevated while the economy recovers and the effects of our pricing actions take hold. Claims experience can fluctuate widely from quarter to quarter and tends to be more stable when measured over a longer period of time.

The benefit ratio for individual disability insurance decreased for the second quarter and first six months of 2012 compared to the same periods of 2011. We generally expect the individual disability benefit ratio to trend down over the long term to reflect growth in the business outside of the large block of individual disability business assumed in 2000 from Minnesota Life, and we expect there to be a corresponding shift in revenues from net investment income to premiums. The anticipated general decrease 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 from investment income to premiums.

46

The following table sets forth the discount rate used for newly incurred long term disability claim reserves and life waiver reserves:

	Three Months Ended
	June 30,     2012			March 31,   2012			June 30,   2011
Discount rate		4.00	%		4.75	%		5.25	%

The discount rate is based on the average rate we receive on newly invested assets during the previous 12 months, less a margin. We also consider our average investment yield and average discount rate on our entire block of claims when deciding whether to increase or decrease the discount rate. The discount rate used for newly established long term disability claim reserves decreased 125 basis points to 4.00% for the second quarter of 2012, from 5.25% for the second quarter of 2011 resulting in a corresponding increase in benefits to policyholders of approximately $9 million. The lower discount rate for the second quarter of 2012 compared to the second quarter of 2011 was primarily the result of the continued low interest rate environment. A 25 basis point increase or decrease in the discount rate results in a corresponding increase or decrease in quarterly pre-tax income of $1.8 million. Any offsetting adjustments of group insurance premium rates due to sustained changes in investment yields can take from one to three years given that most new contracts have rate guarantees in place.

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. Given the movement of future interest rates, this may result in significantly higher or lower discount rates. A sustained low interest rate environment and lower commercial mortgage loan originations and tax-advantaged investments utilization in future quarters could result in future reductions to the discount rate. The margin in our overall block of business for group insurance between the invested asset yield and the weighted-average reserve discount rate at June 30, 2012 and 2011 was 44 and 39 basis points, respectively. See “Liquidity and Capital Resources—Asset-Liability Matching and Interest Rate Risk Management,” for additional information regarding our investments and corresponding interest rate risks.

Operating Expenses

The following table sets forth operating expenses for the Insurance Services segment:

	Three Months Ended June 30,							Six Months Ended June 30,
	2012		2011		Percent    Change			2012		2011		Percent    Change
	(Dollars in millions)
Operating expenses	$	86.5	$	85.7		0.9	%	$	179.1	$	172.2		4.0	%

The increase in Insurance Services operating expenses for the second quarter and first six months of 2012 compared to the same periods of 2011 was primarily related to information technology project costs and increased compensation related costs.

Total assets under administration	$	21,073.7	$	22,041.0		(4.4	)

Income before income taxes in the Asset Management segment decreased for the second quarter and first six months of 2012 compared to the same periods of 2011 primarily due to decrease in bond call premiums, the contribution from the change in fair value of the S&P 500 Index and the change in fair value adjustment of index-based guarantees. See Item 1, “Financial Statements—Condensed Notes to Unaudited Consolidated Financial Statements—Note 8—Derivative Financial Instruments” for further derivatives disclosure.

Revenues

Revenues for the Asset Management segment include retirement plan administration fees, fees on investments held in separate account assets and private client wealth management assets under administration, and investment income on general account assets under administration. Premiums and benefits to policyholders reflect both the sale of life-contingent annuities by our individual annuity business and the conversion of retirement plan assets into life-contingent annuities. Most of the sales for this segment are recorded as deposits and are therefore not reflected as premiums. Individual fixed-rate annuity deposits earn investment income, a portion of which is credited to policyholders.

48

The decrease in revenues for the second quarter of 2012 compared to the same period of 2011 was primarily due to lower administrative fee revenues due to the decline in retirement plan assets under administration. This decrease was primarily due to an elevated level of retirement plan terminations in the second half of 2011.

The increase in revenues for the first six months of 2012 compared to the first six months of 2011 was primarily due to an increase in net investment income due to an increase in invested assets and the effect of the change in fair value of our S&P 500 Index options partially offset by lower administration fee revenues due to the decline in retirement plan assets under administration.

Premiums

Premiums for the Asset Management segment are generated from the sale of life-contingent annuities, which are primarily 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. Increases or decreases in premiums for life-contingent annuities generally correlate with corresponding increases or decreases in benefits to policyholders.

The following table sets forth premiums by line of business for the Asset Management segment:

	Three Months Ended June 30,							Six Months Ended June 30,
	2012		2011		Dollar Change			2012		2011		Dollar Change
	(In millions)
Premiums:

Total premiums	$	1.6	$	1.4	$	0.2		$	3.8	$	4.7	$	(0.9	)

The decrease in individual annuity premiums for the first six months of 2012 compared to the first six months of 2011 was due to the decrease in sales of life-contingent annuities.

Administrative Fee Revenues

Administrative fee revenues for the Asset Management segment include asset-based and plan-based fees related to our retirement plans and private client wealth management businesses, and fees related to the origination and servicing of commercial mortgage loans. The primary driver for administrative fee revenues is the level of assets under administration for retirement plans, which is driven by equity market performance and net customer deposits. Assets under administration that produce administrative fee revenues include retirement plan separate account, retirement plan trust products, private client wealth management and commercial mortgage loans under administration for other investors.

The following tables set forth administrative fee revenues by line of business and associated key indicators for the Asset Management segment:

Commercial mortgage loans for other investors		2,718.9		2,698.7		0.7
Private client wealth management		1,003.7		1,199.7		(16.3	)

The decrease in administrative fee revenues for the second quarter and first six months of 2012 compared to the same periods of 2011 were primarily due to a decline in retirement plan trust products assets under administration due to an elevated level of plan terminations in the second half of 2011. The elevated level of plan terminations in the second half of 2011 reflected the continued economic pressure on some of our small business customers, and the termination of one large plan that was not meeting our profit expectations.

The decrease in net investment income for the second quarter of 2012 compared to the second quarter of 2011 was primarily due to a decline in the portfolio yields for fixed maturity securities and commercial mortgage loans and a change in fair value of our S&P 500 Index options in our individual annuities business, partially offset by an increase in average retirement plan general account and individual annuity assets under administration.

The increase in net investment income for the first six months of 2012 compared to the first six months of 2011 was primarily due to an increase in average individual annuity assets under administration and an increase in average retirement plan general account assets under administration. Net investment income also increased due to a change in fair value of our S&P 500 Index options in our individual annuities business and higher prepayment fees received on commercial mortgage loans. These increases were partially offset by lower portfolio yields for fixed maturity securities and commercial mortgage loans and lower real estate income due to the sale of certain investment properties in 2011.

Benefits and Expenses

Benefits to Policyholders

Benefits to policyholders for the Asset Management segment primarily represent current and future benefits on life-contingent annuities. Changes in the level of benefits to policyholders will generally correlate to changes in premium levels because these annuities are primarily single-premium life-contingent annuity products with a significant portion of all premium payments established as reserves.

The following table sets forth benefits to policyholders for the Asset Management segment:

	Three Months Ended June 30,							Six Months Ended June 30,

Interest Credited

Interest credited represents interest paid to policyholders on retirement plan general account assets, individual fixed-rate annuity deposits and index-based interest guarantees.

The following table sets forth interest credited and associated key indicators for the Asset Management segment for the periods presented:

The decrease in interest credited for the second quarter of 2012 compared to the second quarter of 2011 was primarily due to the change in fair value of our index-based interest guarantees. The increase in interest credited for the first six months of 2012 compared to the first six months of 2011 was primarily due to an increase in our average individual fixed-rate annuity assets under administration and the change in fair value of our index-based interest guarantees. See Item 1, “Financial Statements—Condensed Notes to Unaudited Consolidated Financial Statements—Note 8—Derivative Financial Instruments” for further derivatives disclosure.

Operating Expenses

	(Dollars in millions)
Operating expenses	$	29.3	$	28.9		1.4	%	$	59.5	$	58.3		2.1	%

The increase in Asset Management operating expenses for the second quarter and first six months of 2012 compared to the same periods of 2011 were primarily due to increased administrative and service costs.

Other

In addition to our two segments, we report our holding company and corporate activities in the Other category. This category includes return on capital not allocated to the product segments, holding company expenses, operations of certain unallocated subsidiaries, interest on debt, unallocated expenses, net capital gains and losses and adjustments made in consolidation.

The following table sets forth results for the Other category:

	Three Months Ended June 30,							Six Months Ended June 30,
	2012		2011		Percent Change			2012		2011		Percent Change
	(Dollars in millions)
Loss before income taxes	$	15.9	$	28.4		(44.0	) %	$	29.3	$	43.9		(33.3	) %

The decreases in loss before income taxes for the second quarter and first six months of 2012 compared to the same periods of 2011 were primarily due to a decrease in capital losses recognized on real estate owned in addition to decreases in operating expenses during 2012.

Net Capital Gains (Losses)

Net capital gains and losses are reported in the Other category and are not likely to occur in a stable pattern. Net capital gains and losses primarily occur as a result of sales of our assets for more or less than carrying value, OTTI of assets in our bond portfolio, provisions to our commercial mortgage loan loss allowance, losses recognized due to impairment of real estate and impairments of low-income housing tax credit investments

Net capital losses for the second quarter and the first six months of 2012 were primarily related to our commercial mortgage loan loss allowance provision and losses recognized on real estate owned. These losses were partially offset by net capital gains related to the sale of certain fixed maturity securities.

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 sources of economic risk are interest rate related and include changes in interest rate term risk, credit risk and liquidity risk. 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 likelihood of meeting our financial obligations is increased. See “—Investing Cash Flows.”

We manage interest rate risk, in part, through asset-liability analyses. In accordance with presently accepted actuarial standards, we have 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 June 30, 2012.

Our interest rate risk analysis reflects the influence of call and prepayment rights present in our fixed maturity securities and commercial mortgage loans. The majority of these investments have contractual provisions that require the borrower to compensate us in part or in full for reinvestment losses if the security or loan is retired before maturity. Callable bonds without make-whole provisions represented 7.6% of our fixed maturity security portfolio at June 30, 2012. We also originate commercial mortgage loans containing a make-whole prepayment provision requiring the borrower to pay a prepayment fee. As interest rates decrease, potential prepayment fees increase. These larger prepayment fees deter borrowers from refinancing during a low interest rate environment. Approximately 95% of our commercial mortgage loan portfolio contains this prepayment provision. Almost all of the remaining commercial mortgage loans contain fixed percentage prepayment fees that mitigate prepayments but may not fully protect our expected cash flows in the event of prepayment.

Operating Cash Flows

Net cash provided by operating activities is net income adjusted for non-cash items and accruals, and was $200.0 million for the first six months of 2012, compared to $132.2 million for the first six months of 2011. This increase was driven by a $13.2 million increase in our deferred tax liability, in addition to a $10.4 million decrease in other assets and a $41.9 million increase in other liabilities, mainly attributable to timing differences.

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.

Net cash used in investing activities was $405.1 million and $368.6 million for the first six months of 2012 and 2011, respectively. The increase in net cash used in investing activities for the first six months of 2012 compared to the first six months of 2011 was primarily due to an increase in net purchases of fixed maturity securities during the first six months of 2012.

53

Our target investment portfolio allocation is approximately 60% fixed maturity securities and 40% commercial mortgage loans with a maximum allocation of 45% to commercial mortgage loans. At June 30, 2012, our portfolio consisted of 56.4% fixed maturity securities, 41.2% commercial mortgage loans and 0.8% real estate.

Fixed Maturity Securities

We maintain prudent diversification across industries, issuers and maturities. We have avoided the types of structured products that do not meet an adequate level of transparency for good decision making. Our corporate bond industry diversification targets are based on the Bank of America Merrill Lynch U.S. Corporate Master Index, which is reasonably reflective of the mix of issuers broadly available in the market. Our fixed maturity securities below investment grade are primarily managed by a third party.

Our fixed maturity securities portfolio generates unrealized gains or losses primarily resulting from market interest rates that are lower or higher relative to our book yield at the reporting date. In addition, changes in the spread between the risk-free rate and market rates for any given issuer can fluctuate based on the demand for the instrument, the near-term prospects of the issuer and the overall economic climate.

The following table sets forth fixed maturity securities and associated key indicators:

	June 30,     2012			December 31, 2011			Change

We recorded OTTI of $1.7 million and $2.5 million, and $0.5 million and $1.4 million for the second quarter and first six months of 2012 and 2011, respectively. See “Critical Accounting Policies and Estimates—Investment Valuations—Fixed Maturity Securities.” We did not have any direct exposure to sub-prime or Alt-A mortgages in our fixed maturity securities portfolio at June 30, 2012. At June 30, 2012, our foreign government bonds category did not have any direct exposure to euro zone government issued debt. At June 30, 2012, fixed maturity securities issued by investment and commercial banks headquartered in the euro zone represented 0.7%, or $49.9 million, of our fixed maturity securities portfolio. We did not hold any fixed maturity securities issued by investment and commercial banks headquartered in Portugal, Ireland, Italy, Greece or Spain at June 30, 2012. There were no impairments on fixed maturity securities related to euro zone exposure during the first six months of 2012.

Commercial Mortgage Loans

StanCorp Mortgage Investors, LLC 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. The level of commercial mortgage loan originations in any period is influenced by market conditions as we respond to changes in interest rates, available spreads and borrower demand.

The following table sets forth commercial mortgage loan originations:

	Three Months Ended June 30,							Six Months Ended June 30,
	2012		2011		Percent   Change			2012		2011		Percent Change
	(Dollars in millions)
Commercial mortgage loan originations	$	300.2	$	302.7		(0.8	) %	$	509.7	$	499.0		2.1	%

Commercial mortgage loan originations for the second quarter of 2012 compared to the second quarter of 2011 were consistent. The increase in commercial mortgage loan originations for the first six months of 2012 compared to the first six months of 2011 was primarily due to increased activity in the commercial real estate market during the first half of 2012.

The following table sets forth commercial mortgage loan servicing data:

For other institutional investors		2,718.9		2,691.6		1.0
Capitalized commercial mortgage loan servicing rights associated with commercial mortgage loans serviced for other institutional investors		7.2		7.2		—

The estimated average loan to value ratio for the overall portfolio was less than 70% at June 30, 2012. The average loan balance of our commercial mortgage loan portfolio was approximately $0.8 million at June 30, 2012. We have the contractual ability to pursue personal recourse on approximately 74% of our loans and partial personal recourse on a majority of the remaining loans. The average capitalization rate for the portfolio at June 30, 2012 was approximately 9%. Capitalization rates are used internally to value our commercial mortgage loan portfolio annually.

At June 30, 2012, we did not have any direct exposure to sub-prime or Alt-A mortgages in our commercial mortgage loan portfolio. When we undertake mortgage risk, we do so directly through loans that we originate ourselves rather than in packaged products such as commercial mortgage-backed securities. Given that we service the vast majority of loans in our portfolios, we are prepared to deal with them promptly and proactively. Should the delinquency rate or loss performance of our commercial mortgage loan portfolio increase significantly, the increase could have a material adverse effect on our business, financial position, results of operations or cash flows.

* Geographic regions obtained from the American Council of Life Insurers Mortgage Loan Portfolio Profile.

Our largest concentration of commercial mortgage loan property type was retail properties and primarily consisted of convenience related properties in strip malls, convenience stores and restaurants. Our exposure to retail properties is diversified among various borrowers, properties and geographic regions. In addition, retail commercial lending represents an area of experience and expertise, where careful underwriting and consistent surveillance mitigate risks surrounding our commercial mortgage lending in this area.

At June 30, 2012, our ten largest borrowers represented less than 8% of our total commercial mortgage loan portfolio balance. Our largest borrower concentrations within our commercial mortgage loan portfolio consisted of two borrowers that individually ranged from 1% to 2% of our total commercial mortgage loan portfolio balance.

Through our concentration of commercial mortgage loans in California, we are exposed to potential losses from an economic downturn in California as well as to certain catastrophes, such as earthquakes and fires that may affect certain areas of the western region. We require borrowers to maintain fire insurance coverage. 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 is consistent with our experience in other states. We do not require earthquake insurance for the properties when we underwrite new loans. However, we 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 the western region to have a material adverse effect on our business, financial position, results of operations or cash flows. Currently, our California exposure is primarily in Los Angeles County, Orange County, San Diego County and the Bay Area Counties. We have a smaller concentration of commercial mortgage loans in the Inland Empire and the San Joaquin Valley where there has been greater economic decline. Due to the concentration of commercial mortgage loans in California, a continued economic decline in California could have a material effect on our business, financial position, results of operations or cash flows. See Part II, Item 1A, “Risk Factors.”

56

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 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 June 30, 2012, we had outstanding commitments to fund commercial mortgage loans totaling $161.9 million, with fixed interest rates ranging from 4.375% to 5.750%. 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.

The following table sets forth key commercial mortgage loan statistics:

	June 30, 2012			December 31, 2011			Percent Change
	(Dollars in millions)
Commercial mortgage loans 60 day delinquencies:
Book value	$	15.8		$	17.1			(7.6	) %

In process of foreclosure	$	12.4		$	5.1			143.1
Restructured commercial mortgage loans on a statutory basis		83.4			93.7			(11.0	)

The performance of our commercial mortgage loan portfolio may fluctuate in the future. However, based on our business approach of diligently underwriting high-quality loans, we believe our delinquency rate will remain contained. We have steadfastly avoided the types of structured products that do not meet an adequate level of transparency for good decision making.

The following table sets forth details of our commercial mortgage loans foreclosed or accepted as deeds in lieu of foreclosure:

	Three Months Ended June 30,							Six Months Ended June 30,
	2012		2011		Change			2012		2011		Change
	(Dollars in millions)
Number of loans		11		9		2			22		21		1

Number of properties foreclosed and transferred to REO		10		11		(1	)		19		22		(3	)
Real estate acquired	$	6.5	$	4.9	$	1.6		$	13.3	$	10.1	$	3.2

Commercial mortgage loan foreclosures may result in the sale of the property to a third party at the time of foreclosure, resulting in fewer properties transferred to real estate owned than the number of loans foreclosed during the period. Commercial mortgage loans may have multiple properties as collateral, resulting in more properties transferred to real estate owned than the number of loans foreclosed during the period. Real estate acquired through foreclosure or accepted as deeds in lieu of foreclosure is initially recorded at the lower of cost or estimated net realizable value, which includes an estimate for disposal costs. These amounts may be adjusted in a subsequent period as additional market information is received. The book value of real estate acquired during the second quarter and first six months of 2012 increased compared to the same periods of 2011 primarily due to the properties acquired having higher average net realizable values in the second quarter and first six months of 2012. See “Critical Accounting Policies and Estimates—Investment Valuations—Commercial Mortgage Loans” for our commercial mortgage loan loss allowance policy.

57

The following table sets forth changes in the commercial mortgage loan loss allowance:

	Three Months Ended June 30,									Six Months Ended June 30,
	2012			2011			Dollar Change			2012			2011			Dollar Change
	(In millions)
Commercial mortgage loan loss allowance:

Ending balance	$	45.6		$	43.5		$	2.1		$	45.6		$	43.5		$	2.1

The larger commercial mortgage loan loss allowance as of June 30, 2012 compared to June 30, 2011 was primarily due to the net increase in the general reserve during the second quarter and first six months of 2012. The smaller increase in the provision and lower charge-offs for the second quarter and first six months of 2012 compared to the same periods of 2011 were primarily related to lower losses associated with foreclosures, accepted deeds in lieu of foreclosure on commercial mortgage loans and other related charges associated with commercial mortgage loans leaving the portfolio during the second quarter and first six months of 2012.

The following table sets forth impaired commercial mortgage loans identified in management’s specific review of probable loan losses and the related allowance:

	June 30, 2012			December 31, 2011			Dollar Change
	(In millions)
Impaired commercial mortgage loans with specific allowances for losses	$	74.5		$	75.8		$	(1.3	)
Impaired commercial mortgage loans without specific allowances for losses		24.9			28.9			(4.0	)
Specific allowance for losses on impaired commercial mortgage loans, end of the period		(24.6	)		(26.6	)		2.0
Net carrying value of impaired commercial mortgage loans	$	74.8		$	78.1		$	(3.3	)

An impaired commercial mortgage loan is a loan where we do not expect to receive contractual principal and interest in accordance with the terms of the loan agreement. A specific allowance for losses is recorded when a loan is considered to be impaired and it is probable that all amounts due will not be collected. We also hold specific allowances for losses on certain performing loans that we continue to monitor and evaluate. Impaired commercial mortgage loans without specific allowances for losses are those for which we have determined that it remains probable that we will collect all amounts due. The decrease in the impaired commercial mortgage loans at June 30, 2012 compared to December 31, 2011 was primarily due to more loans in this category paying off or being foreclosed during the first six months of 2012.

The following table sets forth the average recorded investment in impaired commercial mortgage loans before specific allowance for losses:

	Three Months Ended June 30,						Six Months Ended June 30,
	2012		2011		Dollar Change		2012		2011		Dollar Change
	(In millions)
Average recorded investment	$	101.8	$	91.0	$	10.8	$	102.8	$	88.1	$	14.7

Interest income is recorded in net investment income. We continue to recognize interest income on delinquent commercial mortgage loans until the loans are more than 90 days delinquent. Interest income and accrued interest receivable are reversed when a loan is put on non-accrual status. For loans that are less than 90 days delinquent, we may reverse interest income and the accrued interest receivable if there is a question on the collectability of the interest. Interest income on loans in the 90-day delinquent category is recognized in the period the cash is collected. We resume the recognition of interest income when the loan becomes less than 90 days delinquent and we determine it is probable that the loan will remain performing.

The amount of interest income recognized on impaired commercial mortgage loans was $1.0 million and $0.9 million for the second quarters of 2012 and 2011, respectively and was $2.1 million for the first six months of 2012 and 2011. The cash received by us in payment of interest on impaired commercial mortgage loans was $0.9 million and $0.7 million for the second quarters of 2012 and 2011, respectively and was $2.0 million and $1.4 million for the first six months of 2012 and 2011, respectively.

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 $196.2 million and $195.5 million for the first six months of 2012 and 2011, respectively. The increase in funds provided by financing cash flows for the comparative periods was primarily due to a decrease in repurchases of common stock. The increase was offset by a decrease in the level of policyholder funds, net of withdrawals. See “Capital Management—Share Repurchases” for further discussion on share repurchases.

On June 22, 2012, we entered into an agreement for a four-year, $250 million credit facility (the “Facility”). Additionally, upon our request and with consent of the lenders under the Facility, the Facility can be increased to $350 million. The termination date of the Facility is June 22, 2016 though, at our option and with the consent of the lenders under the Facility, the termination date can be extended for two additional one year periods. Borrowings under the Facility will be used to provide for working capital, for issuance of letters of credit and for our general corporate purposes.

Under the agreement, we are 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. Under the two financial covenants, we are required to maintain a total debt to capitalization ratio that does not exceed 35% and a consolidated net worth that is equal to at least $1.21 billion. The financial covenants exclude the unrealized gains and losses related to fixed maturity securities that are held in accumulated other comprehensive income (loss). At June 30, 2012, we had a total debt to total capitalization ratio of 24.2% and consolidated net worth of $1.73 billion as defined by the financial covenants. We believe we will continue to meet the financial covenants in the future. The Facility is subject to performance pricing based upon the Company’s publicly announce debt ratings and includes an interest rate option at the election of the borrower of a base rate plus the applicable margin or the LIBOR rate plus the applicable margin, plus facility and utilization fees. At June 30, 2012, we were in compliance with all covenants under the Facility and had no outstanding balance on the Facility.

We have $250 million of 6.875%, 10-year senior notes (“2012 Senior Notes”), which mature on October 1, 2012 and are considered short-term debt. The principal amount of the 2012 Senior Notes is payable at maturity and interest is payable semi-annually in April and October. On August 3, 2012, we priced a public offering of $250 million of senior notes (“2022 Senior Notes”) which will have a final maturity of August 15, 2022. The 2022 Senior Notes will bear an annual interest rate of 5.00%. Interest will be paid semi-annually on February 15 and August 15, beginning on February 15, 2013. We intend to use the net proceeds, together with cash on hand, to repay our $250 million of 6.875% 10-year 2012 Senior Notes due October 1, 2012. We intend to close this public offering on August 10, 2012.

We have $300 million of 6.90%, junior subordinated debentures (“Subordinated Debt”). The Subordinated Debt has a final maturity on June 1, 2067, is non-callable at par for the first 10 years (prior to June 1, 2017). 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 up to June 1, 2017, and quarterly thereafter at a floating rate equal to three-month London Interbank Offered Rate plus 2.51%. We have the option to defer interest payments for up to five years. We have not deferred interest on the Subordinated Debt.

Capital Management

State insurance departments require insurance enterprises to maintain minimum levels of capital and surplus. The target for our insurance subsidiaries is generally to maintain statutory 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 estimated statutory capital of 333% of the Company Action Level RBC at June 30, 2012. At June 30, 2012, statutory capital, adjusted to exclude asset valuation reserves, for our regulated insurance subsidiaries totaled $1.36 billion.

Statutory capital growth from our insurance subsidiaries is generally a result of generated income, less a charge for business growth, measured by insurance premium growth, which includes individual annuity sales. The level of capital in excess of targeted RBC we generate varies inversely in relation to the level of our premium growth. As premium growth increases, capital is utilized to fund additional reserve requirements, meet increased regulatory capital requirements based on premium and cover certain acquisition costs associated with policy issuance, leaving less available capital beyond our target level. Higher levels of premium growth can result in increased utilization of capital beyond that which is generated by the business, and at very high levels of premium growth, we could generate the need for capital infusions. At lower levels of premium growth, additional capital produced by the business exceeds the capital utilized to meet these requirements, which can result in additional capital above our targeted RBC level. In assessing our capital position, we also consider cash and capital at the holding company and non-insurance subsidiaries.

Investments

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 the admissibility of investments to bonds and other fixed maturity securities, commercial 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 Boards of Directors of our insurance subsidiaries. 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 Audit Committee of the Board of Directors for Standard Insurance Company (“Standard”) and to the Board of Directors for The Standard Life Insurance Company of New York.

Dividends from Standard

Our ability to pay dividends to our shareholders, repurchase our shares and meet our obligations substantially depends upon the receipt of distributions from our subsidiary 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 capital according to Oregon statute. Under Oregon law, Standard may pay dividends and other distributions only from the earned surplus arising from its business. If the proposed dividend or other distribution 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 and 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 approve or decline requests for dividends and other distributions in excess of these limits. There are no regulatory restrictions on dividends from our non-insurance subsidiaries.

As of December 31, 2011, Standard’s net gain from operations after dividends to policyholders and federal income taxes and before capital gains or losses for the 12-month period then ended was $144.0 million and capital and surplus was $1.19 billion. Based upon Standard’s results for 2011, the amount of ordinary dividends and other distributions available in 2012 without additional approval from the Oregon Insurance Division is $144.0 million.

Dividends paid from Standard to StanCorp will be based on levels of available capital and needs at the holding company, which are driven by the financial results of Standard and the Company as a whole. Standard did not pay ordinary cash dividends to StanCorp during the second quarter of 2012. Standard paid ordinary cash dividends to StanCorp of $45.0 million for the second quarter of 2011. Standard paid ordinary cash dividends to StanCorp of $10.0 million and $57.8 million for the first six months of 2012 and 2011, respectively.

Dividends to Shareholders

The declaration and payment of dividends to shareholders in the future is subject to the discretion of our Board of Directors. It is anticipated that annual dividends to shareholders will be paid in December of each year depending on our financial condition, results of operations, cash requirements, future prospects, regulatory restrictions on dividends from the insurance subsidiaries, the ability of the insurance subsidiaries to maintain adequate capital and other factors deemed relevant by our Board of Directors. In addition, the declaration and payment of dividends would be restricted if we elect to defer interest payments on our Subordinated Debt dated as of May 21, 2007. If elected, the restriction would be in place during the interest deferral period, which cannot exceed five years. We have not deferred interest on the Subordinated Debt, and have paid dividends each year since our initial public offering in 1999. In the fourth quarter of 2011, StanCorp paid an annual cash dividend of $0.89 per share, totaling $39.3 million.

Share Repurchases

On May 16, 2011, our Board of Directors authorized an additional 3.0 million shares of StanCorp common stock for its share repurchase program. The May 2011 authorization took effect upon the expiration of the February 2010 authorization and expires on December 31, 2012. Share repurchases under the repurchase program are made in the open market or in negotiated transactions in compliance with the safe harbor provisions of Rule 10b-18 under regulations of the Securities Exchange Act of 1934 (“Exchange Act”). Execution of the share repurchase program is based upon management’s assessment of market conditions for its common stock, capital levels, our assessment of the overall economy and other potential growth opportunities or priorities for capital use. Repurchases are made at market prices on the transaction date.

The following table sets forth share repurchases activity:

	Three Months Ended June 30,				Six Months Ended June 30,
	2012		2011		2012		2011
	(Dollars in millions except per share data)

Financial Strength and Credit Ratings

Financial strength ratings are gauges of our claims paying ability and are an important factor in establishing the competitive position of insurance companies. In addition, ratings are important for maintaining public confidence in our company and in our ability to market our products. Rating organizations regularly review the financial performance and condition of insurance companies. 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, adversely affect our ability to market our products and increase costs of future debt issuances.

S&P, Moody’s Investors Service, Inc. (“Moody’s”) and A.M. Best Company (“A.M. Best”) provide financial strength ratings on Standard.

Standard’s financial strength ratings as of August 2012 were:

S&P	Moody’s	A.M. Best
A+ (Strong)	A2 (Good)	A (Excellent)(1)
5th of 20 ratings	6th of 21 ratings	3rd of 13 ratings
Outlook: Negative	Outlook: Negative	Outlook: Stable

(1) Also includes Standard Life Insurance Company of New York

Credit ratings assess credit quality and the likelihood of issuer default. S&P, Moody’s and A.M. Best provide ratings on StanCorp’s Senior Notes and Subordinated Debt. S&P and A.M. Best also provide issuer credit ratings for both Standard and StanCorp.

Our debt ratings and issuer credit ratings as of August 2012, which we believe are indicators of our liquidity and ability to make payments, were:

	S&P	Moody’s	A.M. Best
StanCorp debt ratings:
2012 Senior Notes	BBB+	Baa2	bbb
Subordinated Debt	BBB-	Baa3	bb+
Issuer credit ratings:
Standard	A+	—	a(1)
StanCorp	BBB+	—	bbb
Outlook	Negative	Negative	Stable(1)

(1) Also includes Standard Life Insurance Company of New York

In April 2012, Moody’s lowered the financial strength rating for Standard and the debt and issuer credit ratings for StanCorp. Moody’s downgraded the insurance financial strength rating of Standard to “A2”, our senior unsecured debt to “Baa2” and our subordinated debt to “Baa3”.

In July 2012, both Moody’s and S&P changed their outlook for the ratings of Standard and StanCorp to Negative from Stable.

In August 2012, A.M. Best affirmed the financial strength rating of “A” for Standard and Standard Life Insurance Company of New York with a Stable outlook. A.M. Best lowered the issuer credit ratings for Standard and Standard Life Insurance Company of New York to “a” from “a+” and StanCorp to “bbb” from “bbb+”. A.M. Best also lowered the debt ratings on StanCorp’s 2012 Senior Notes to “bbb” from “bbb+” and StanCorp’s Subordinated Debt to “bb+” from “bbb-”. A.M. Best also changed their outlook for the credit and debt ratings of Standard, Standard Life Insurance Company of New York and StanCorp to Stable from Negative. These changes in ratings and outlook are primarily due to less favorable claims experience in our group long term disability business. Our ratings continue to be high quality investment grade, and we are well positioned within the insurance industry.

We believe our well-managed underwriting and claims operations, high-quality invested asset portfolios, enterprise risk management processes and strong capital position will continue to support our financial strength ratings and strong credit standing. See “Liquidity and Capital Resources—Asset-Liability Matching and Interest Rate Risk Management,” and “Capital Management.” In addition, we remain well within our line of credit financial covenants. See “Liquidity and Capital Resources—Financing Cash Flows.”

Off-Balance Sheet Arrangements

See discussion of loan commitments, “Liquidity and Capital Resources—Investing Cash Flows—Commercial Mortgage Loans.”

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, 2010 through June 30, 2012 aggregated $1.1 million. At June 30, 2012, we maintained a reserve of $0.5 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.

The following table sets forth the difference between the statutory net gains from insurance operations before federal income taxes and net capital gains and losses (“Statutory Results”) and GAAP income before income taxes excluding net capital gains and losses (“Adjusted GAAP Results”):

	Three Months Ended June 30,								Six Months Ended June 30,
	2012		2011			Dollar Change			2012			2011			Dollar Change
	(In millions)
Statutory Results	$	31.0	$	32.6		$	(1.6	)	$	73.1		$	76.3		$	(3.2	)
Adjusted GAAP Results		26.6		37.7			(11.1	)		74.5			89.6			(15.1	)
Difference	$	4.4	$	(5.1	)	$	9.5		$	(1.4	)	$	(13.3	)	$	11.9

The decreases in Statutory Results for the second quarter and first six months of 2012 compared to the same periods of 2011 were primarily due to an increase in group long term disability reserves related to higher claims experience and a 75 basis point reduction in the discount rate used for newly established long term disability claims. The change in direction of the spread between Statutory Results and Adjusted GAAP Results for the second quarter of 2012 was primarily due to a narrowing difference in DAC and the change in fair value for our S&P 500 Index Options. The spread between Statutory Results and adjusted GAAP results for the first six months of 2012 was due to a narrowing difference in DAC and a reduction in the amortization of the Interest Maintenance Reserve for statutory results.

The following table sets forth statutory capital and the associated asset valuation reserve:

	June 30, 2012		December 31, 2011		Percent Change
	(Dollars in millions)
Statutory capital adjusted to exclude asset valuation reserves for our regulated insurance subsidiaries	$	1,358.3	$	1,300.3		4.5	%
Asset valuation reserve		114.4		107.2		6.7

Accounting Pronouncements

See Item 1, “Financial Statements—Condensed Notes to Unaudited Consolidated Financial Statements—Note 11—Accounting Pronouncements.”

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 disclosures of 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 investment valuations, DAC, VOBA and other intangible assets, the reserves for future policy benefits and claims, pension and postretirement benefit plans 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 our performance. These estimates have a material effect on our results of operations and financial condition.

Investment Valuations

Fixed Maturity Securities

Fixed maturity security capital gains and losses are recognized using the specific identification method. If a debt security’s fair value declines below its amortized cost, we must assess the security’s impairment to determine if the impairment is other than temporary.

In our quarterly fixed maturity security impairment analysis, we evaluate whether a decline in value of the fixed maturity security is other than temporary by considering the following factors:

• The nature of the fixed maturity security.

• The duration until maturity.

• The duration and extent the fair value has been below amortized cost.

• The financial quality of the issuer.

62

• Estimates regarding the issuer’s ability to make the scheduled payments associated with the fixed maturity security.

• Our intent to sell or whether it is more likely than not we will be required to sell a fixed maturity security before recovery of the security’s cost basis through the evaluation of facts and circumstances including, but not limited to, decisions to rebalance our portfolio, current cash flow needs and sales of securities to capitalize on favorable pricing.

If it is determined an OTTI exists, we separate the OTTI of debt securities into an OTTI related to credit loss and an OTTI related to noncredit loss. The OTTI related to credit loss represents the portion of losses equal to the difference between the present value of expected cash flows, discounted using the pre-impairment yields, and the amortized cost basis. All other changes in value represent the OTTI related to noncredit loss. The OTTI related to credit loss is recognized in earnings in the current period, while the OTTI related to noncredit loss is deemed recoverable and is recognized in other comprehensive income. The cost basis of the fixed maturity security is permanently adjusted to reflect the credit related impairment. Once an impairment charge has been recorded, we continue to review the OTTI securities for further potential impairment.

We maintain an internally identified list of securities with characteristics that could indicate potential impairment (“watch list”). At June 30, 2012, our fixed maturity securities watch list totaled $7.9 million at fair value and $8.8 million at amortized cost. We recorded $1.7 million and $2.5 million of OTTI related to credit loss due to impairments for the second quarter and first six months of 2012, compared to credit losses of $0.5 million and $1.4 million of OTTI for the second quarter and first six months of 2011, respectively. We recorded no OTTI related to noncredit loss for the second quarter and first six months of 2012 and 2011. See Item 1, “Financial Statements—Notes to Unaudited Consolidated Financial Statements—Note 7—Investments” for further disclosures.

We will continue to evaluate our holdings; however, we currently expect the fair values of our investments to recover either prior to their maturity dates or upon maturity. Should the credit quality of our fixed maturity securities significantly decline, there could be a material adverse effect on our business, financial position, results of operations or cash flows.

In conjunction with determining the extent of credit losses associated with debt securities, we utilize certain information in order to determine the present value of expected cash flows discounted using pre-impairment yields. Some of these input factors include, but are not limited to, original scheduled contractual cash flows, current market spread information, risk-free rates, fundamentals of the industry and sector in which the issuer operates, and general market information.

Fixed maturity securities are classified as available-for-sale and are carried at fair value on the consolidated balance sheet. See Item 1, “Financial Statements—Notes to Unaudited Consolidated Financial Statements—Note 6—Fair Value” for a detailed explanation of the valuation methods we use to calculate the fair value of our financial instruments. Valuation adjustments for fixed maturity securities not accounted for as OTTI are reported as net increases or decreases to other comprehensive income (loss), net of tax, on the consolidated statements of income and comprehensive income.

Commercial Mortgage Loans

The carrying value of commercial mortgage loans represents the outstanding principal balance less a loan loss allowance for probable uncollectible amounts. The commercial mortgage loan loss allowance is estimated based on evaluating known and inherent risks in the loan portfolio and consists of a general loan loss allowance and a specific loan loss allowance. The general loan loss allowance is based on our analysis of factors including changes in the size and composition of the loan portfolio, actual loan loss experience and individual loan analysis. An impaired commercial mortgage loan is a loan that is not performing to the contractual terms of the loan agreement. A specific allowance for losses is recorded when a loan is considered to be impaired. We also hold specific allowances for losses on certain performing loans that we continue to monitor and evaluate. Impaired commercial mortgage loans without specific allowances for losses are those for which we have determined that it remains probable that we will collect all amounts due. In addition, for impaired commercial mortgage loans, we evaluate the loss to dispose of the underlying collateral, any significant out of pocket expenses the loan may incur, the loan-to-value ratio and other quantitative information we have concerning the loan. Portions of loans that are deemed uncollectible are generally written off against the allowance, and recoveries, if any, are credited to the allowance. See “Liquidity and Capital Resources—Investing Cash Flows—Commercial Mortgage Loans.”

Real Estate

Real estate is comprised of two components: real estate investments and real estate owned.

Our real estate investments are stated at cost less accumulated depreciation. Generally, we depreciate this real estate using the straight-line depreciation method with property lives varying from 30 to 40 years.

We record impairments when it is determined that the decline in fair value of an investment below its carrying value is other than temporary. The impairment loss is charged to net capital losses, and the cost basis of the investment is permanently adjusted to reflect the impairment.

Real estate owned is initially recorded at the lower of cost or estimated net realizable value, which includes an estimate for disposal costs. This amount may be adjusted in a subsequent period as additional information is received. Our real estate owned is initially considered an investment held for sale and is expected to be sold within one year from acquisition. For any real estate expected to be sold, an impairment charge is recorded if we do not expect the investment to recover its carrying value prior to the expected date of sale. Once an impairment charge has been recorded, we continue to review the investment for further potential impairment.

Total real estate was $104.1 million at June 30, 2012, compared to $92.7 million at December 31, 2011. The $11.4 million increase in total real estate during the first six months of 2012 was primarily due to an $11.8 million net increase in real estate owned that was acquired in satisfaction of debt through foreclosure or the acceptance of deeds in lieu of foreclosure on commercial mortgage loans.

63

All Other Investments

Other invested assets include low income housing tax credit investments, derivative financial instruments and policy loans. Valuation adjustments for these investments are recognized using the specific identification method.

Low income housing tax credit investments are accounted for under the equity method of accounting. Valuation adjustments are reported as capital losses.

Derivative financial instruments are carried at fair value, and valuation adjustments are reported as a component of net investment income. See “Note 8—Derivative Financial Instruments.”

Policy loans are stated at their aggregate unpaid principal balances and are secured by policy cash values.

Net investment income and capital gains and losses related to separate account assets and liabilities are included in the separate account assets and liabilities.

DAC, VOBA and Other Intangible Assets

DAC, VOBA and other acquisition related 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.

In October 2010, the FASB issued Accounting Standards Update (‘ASU’) No. 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts. ASU No. 2010-26 amends the codification guidance for insurance entities to eliminate the diversity of accounting treatment related to deferred acquisition costs. The Company has adopted this standard retrospectively as of January 1, 2012, and comparative financial statements of prior periods have been adjusted.

The following table sets forth the balances of DAC, VOBA and other intangible assets:

	June 30,         2012		December 31,     2011		Percent         Change
	(Dollars in millions)
DAC	$	285.0	$	274.4		3.9	%
VOBA		24.3		26.4		(8.0	)
Other intangible assets		41.1		44.1		(6.8	)
Total DAC, VOBA and other intangible assets	$	350.4	$	344.9		1.6	%

We defer certain acquisition costs that vary with and are directly related to the origination of 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. Changes in actual persistency are reflected in the calculated DAC balance. Costs that are not directly associated with the acquisition of new business are not deferred as DAC and are charged to expense as incurred. Generally, annual commissions are considered expenses and are not deferred.

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. We amortize 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. For our individual deferred annuities, DAC is generally amortized over 30 years with approximately 55% and 95% expected to be amortized by years 5 and 15, respectively. DAC for group annuity products is amortized over 10 years with approximately 80% 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 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, 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. During the first quarter of 2012, the Company recorded an $0.8 million impairment to VOBA due to experience related to the block of claims assumed from TIAA. The VOBA associated with the TIAA transaction is amortized in proportion to expected gross profits with an amortization period of up to 20 years. For the VOBA associated with the Minnesota Life block of business assumed, the amortization period is up to 30 years and is amortized in proportion to future premiums. The accumulated amortization of VOBA was $64.5 million and $62.4 million at June 30, 2012 and December 31, 2011, respectively.

64

The following table sets forth the amount of DAC and VOBA balances amortized in proportion to expected gross profits and the percentage of the total balance of DAC and VOBA amortized in proportion to expected gross profits:

	June 30, 2012					December 31, 2011
	Amount		Percent			Amount		Percent
	(Dollars in millions)
DAC	$	64.4		22.6	%	$	60.7		22.1	%
VOBA		6.1		25.1			7.1		26.9

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

• Persistency.

• Interest rates, which affect both investment income and interest credited.

• Stock market performance.

• Capital gains and losses.

• Claim termination rates.

• Amount of business in force.

These assumptions are modified to reflect actual experience when appropriate. Although a change in a single assumption may have an impact on the calculated amortization of DAC or VOBA for balances associated with investment contracts, 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 vary from those assumed, we revise these assumptions annually to reflect our 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.

The following table sets forth the impact of unlocking on DAC and VOBA balances:

	Three Months Ended June  30,				Six Months Ended June 30,
	2012		2011		2012		2011
	(In millions)
Decrease to DAC and VOBA	$	0.3	$	0.6	$	1.1	$	0.6

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 our financial position or results of operations. However, future changes in DAC and VOBA balances due to changes in underlying assumptions are not expected to be material.

Our other intangible assets are subject to amortization and consist of certain customer lists from Asset Management business acquired and an individual disability marketing agreement. Customer lists have a combined estimated weighted-average remaining life of approximately 8.4 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 Minnesota Life marketing agreement will be fully amortized by the end of 2023. The accumulated amortization of other intangible assets was $33.6 million and $30.6 million at June 30, 2012 and December 31, 2011, respectively.

Reserves for Future Policy Benefits and Claims

Reserves include policy reserve liabilities and claim reserve liabilities and represent amounts to pay future benefits and claims. Claim reserve liabilities are for claims that have been incurred or are estimated to have been incurred but not yet reported to us. Policy reserve liabilities reflect our best estimate of assumptions at the time of policy issuance including adjustments for adverse deviations in actual experience.

The following table sets forth total reserve balances by reserve type:

	June 30,              2012		December 31,          2011
	(In millions)
Reserves:
Policy reserves	$	1,069.0	$	1,061.2
Claim reserves		4,704.0		4,622.4
Total reserves	$	5,773.0	$	5,683.6

Developing the estimates for reserves, and thus 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 reserve calculation methodology is prescribed by various accounting and actuarial standards, although judgment is required in the determination of assumptions used in the calculation. We also hold reserves that lack a prescribed methodology but instead are determined by a formula that 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 are primarily incurred but not reported (“IBNR”) claim reserves associated with our disability products. 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.

Policy Reserves

Policy reserves include reserves established for individual disability insurance, individual and group immediate annuity businesses and individual life insurance. Policy reserves are calculated using our best estimates of assumptions and considerations at the time the policy was issued, adjusted 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. We maintain a policy reserve for as long as a policy is in force, even after a separate claim reserve is established.

The following table sets forth policy reserves by block of business:

	June 30,          2012		December 31,          2011
	(In millions)
Policy reserves:
Individual disability insurance	$	226.2	$	219.8
Individual and group immediate annuity businesses		243.4		244.2
Individual life insurance		599.4		597.2
Total policy reserves	$	1,069.0	$	1,061.2

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

66

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.

Individual and group immediate annuity businesses.    Policy reserves for our individual and group immediate annuity blocks of business 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.

Individual life insurance.    Effective January 1, 2001, substantially all of our individual life policies and the associated reserves were ceded to Protective Life Insurance Company (“Protective Life”) under a reinsurance agreement. If Protective Life were to become unable to meet its obligations, Standard would retain the reinsured liabilities. Therefore, the associated reserves remain on Standard’s consolidated balance sheets and an equal amount is recorded as a recoverable from the reinsurer. We also retain a small number of individual policies arising out of individual conversions from our group life policies.

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, equal our best estimate of the present value of the liability of future unpaid claims and claim adjustment expenses. Reserves for IBNR claims are determined using our experience and consider actual historical incidence rates, claim-reporting patterns and the average cost of claims. The IBNR claim reserves are calculated using a company derived formula based primarily upon premiums, which is validated through a close examination of reserve run-out experience. The claim reserves are related to group and individual disability insurance and group life insurance products offered by our Insurance Services segment.

Claim reserves are subject to revision based on credible changes in claim experience and expectations of future factors that may influence claim experience. During each quarter, we monitor our emerging claim experience to ensure that the claim reserves remain appropriate. We make adjustments to our assumptions based on emerging trends that are credible and are expected to persist, and expectations of future factors that may influence our claim experience. 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.

The following table sets forth total claim reserves by block of business:

	June 30,              2012		December 31,          2011
	(In millions)
Claim reserves:
Group disability insurance	$	3,210.4	$	3,135.2
Individual disability insurance		727.7		721.8
Group life insurance		765.9		765.4
Total claim reserves	$	4,704.0	$	4,622.4

Group and individual disability insurance.    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.

67

Group life insurance.    Claim reserves for our group life 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 claim reserves are 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:

• The discount rate.

• The claim termination rate.

• The claim incidence rate for policy reserves and IBNR claim reserves.

The following table sets forth the discount rate used for newly incurred long term disability claim reserves and life waiver reserves:

	Three Months Ended
	June 30,         2012			March 31,          2012			June 30,         2011
Discount rate		4.00	%		4.75	%		5.25	%

Reserve discount rates for newly incurred claims are reviewed quarterly and, if necessary, are adjusted to reflect our current and expected new investment yields. The discount rate is based on the average rate we received on newly invested assets during the previous 12 months, less a margin. We also consider our average investment yield and average discount rate on our entire block of claims when deciding whether to increase or decrease the discount rate. The 75 basis point decrease in the discount rate for the second quarter of 2012 compared to the first quarter of 2012 was primarily the result of a continued low interest rate environment and fewer investments in high yielding tax-advantage investments. A 75 basis point decrease in the discount rate for newly incurred claims results in a corresponding decrease in quarterly pre-tax income of $5.4 million. We do not adjust group insurance premium rates based on short-term fluctuations in investment yields. Any offsetting adjustments of group insurance premium rates due to sustained changes in investment yields 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. While we have experienced some variation in our claim termination experience, we did not see any prolonged or systemic change in the second quarter of 2012 that would indicate a sustained underlying trend that would affect the claim termination rates used in the calculation of reserves.

The claims incidence rate for policy reserves and IBNR claim reserves can also fluctuate widely from quarter to quarter and tends to be more stable when measured over a longer period of time. Claims incidence for the second quarter of 2012 compared to the same period of 2011 for our long term disability insurance business remained elevated.

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 $8.0 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.

Pension and Postretirement Benefit Plans

We have 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 and the agent pension plan is for former field employees and agents. The defined benefit pension plans provide benefits based on years of service and final average pay. Participation in the defined benefit pension plans is generally limited to eligible employees whose date of employment began before 2003. These plans are sponsored by Standard and administered by Standard Retirement Services, Inc. and are closed for new participants.

We also have a postretirement benefit plan that includes medical and prescription drug benefits. A group term life insurance benefit was curtailed as of December 31, 2011. 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. Participation in the postretirement benefit plan is limited to employees who had reached the age of 40 or whose combined age and length of service was equal to or greater than 45 years as of January 1, 2006. This plan is sponsored and administered by Standard and is closed for new participants.

In addition, eligible executive officers are covered by a non-qualified supplemental retirement plan.

We are required to recognize the funded status of our pension and postretirement benefit plans as an asset or liability on the balance sheet. For pension plans, this is measured as the difference between the plan assets at fair value and the projected benefit obligation as of the year-end balance sheet date. For our postretirement plan, this is measured as the difference between the plan assets at fair value and the accumulated benefit obligation as of the year-end balance sheet date. Unrecognized actuarial gains or losses, prior service costs or credits, and transition assets are amortized, net of tax, out of accumulated other comprehensive income or loss as components of net periodic benefit cost.

68

In accordance with the accounting principles related to our pension and other postretirement plans, we are required to make a significant number of assumptions in order to calculate the related liabilities and expenses each period. The major assumptions that affect net periodic benefit cost and the funded status of the plans include the weighted-average discount rate, the expected return on plan assets, and the rate of compensation increase.

The weighted-average discount rate is an interest assumption used to convert the benefit payment stream to present value. The discount rate is selected based on the yield of a portfolio of high quality corporate bonds with durations that are similar to the expected distributions from the employee benefit plan.

The expected return on plan assets assumption is the best long-term estimate of the average annual return that will be produced from the pension trust assets until current benefits are paid. Our expectations for the future investment returns of the asset categories are based on a combination of historical and projected market performance. The expected return for the total portfolio is calculated based on each plan’s strategic asset allocation.

The long-term rate of return for the employee pension plan portfolio is derived by calculating the average return for the portfolio monthly, from 1971 to the present, using the average mutual fund manager returns in each asset category, weighted by the target allocation to each category.

The rate of compensation increase is a long-term assumption that is based on an estimated inflation rate in addition to merit and promotion-related compensation increase components.

For the postretirement benefit plan, the assumed health care cost trend rates are also major assumptions that affect expenses and liabilities. Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. A one-percentage-point change in assumed health care cost trend rates would have the following effects:

	1% Point Increase		1% Point Decrease
	(In millions)
Effect on total of service and interest cost	$	0.5	$	(0.4	)
Effect on postretirement benefit obligation		7.1		(5.6	)

Our discount rate assumption is reviewed annually, and we use a December 31 measurement date for each of our plans. For more information concerning our pension and postretirement plans, see Item 1, “Financial Statements—Condensed Notes to Unaudited Consolidated Financial Statements—Note 4—Retirement Benefits.”

Income Taxes

We file a U.S. consolidated income tax return that includes all subsidiaries. Our U.S. income tax is calculated using regular corporate income tax rates on a tax base determined by laws and regulations administered by the Internal Revenue Service (‘IRS’). We also file corporate income tax returns in various states. The provision for income taxes includes amounts currently payable and deferred amounts that result from temporary differences between financial reporting and tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply when the temporary differences are expected to reverse.

GAAP requires management to use a more likely than not standard to evaluate whether, based on available evidence, each deferred tax asset will be realized. A valuation allowance is recorded to reduce a deferred tax asset to the amount expected to be realized. We have recorded a deferred tax asset for certain loss carry forwards. Realization is dependent on generating sufficient taxable income prior to expiration of the loss carryforwards. Although realization is not assured, management believes it is more likely than not that all of the deferred tax assets without a valuation allowance will be realized. The amount of the deferred tax asset considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carryforward period are reduced.

Management is required to determine whether tax return positions are more likely than not to be sustained upon audit by taxing authorities. Tax benefits of uncertain tax positions, as determined and measured by this interpretation, cannot be recognized in our financial statements.

We record income tax interest and penalties in the income tax provision according to our accounting policy.

Currently, years 2008 through 2011 are open for audit by the IRS.

Forward-looking Statements

Some of the statements contained in this Form 10-Q, including those relating to our strategy, growth prospects and other statements that are predictive in nature, that depend on or refer to future events or conditions or that include words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “estimates,” “seeks” and similar expressions, are forward-looking statements within the meaning of Section 21E of the Exchange Act, as amended. These statements are not historical facts but instead represent only management’s expectations, estimates and projections regarding future events. Similarly, these statements are not guarantees of future performance and involve uncertainties that are difficult to predict, which may include, but are not limited to, the factors discussed below. As a provider of financial products and services, our results of operations may vary significantly in response to economic trends, interest rate changes, investment performance and claims experience. Caution should be used when extrapolating historical results or conditions to future periods.

Our actual results and financial condition may differ, perhaps materially, from the anticipated results and financial condition in any such forward-looking statements. Because such statements are subject to risks and uncertainties, actual results in future periods may differ materially from those expressed or implied by such forward-looking statements. Given these uncertainties or circumstances, readers are cautioned not to place undue reliance on such statements. We assume no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

ITEM 1: LEGAL PROCEEDINGS

See Part 1, Item 1, “Financial Statements—Condensed Notes to Unaudited Consolidated Financial Statements—Note 10—Commitments and Contingencies.”

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, may prove to be inadequate—For certain of our product lines, we establish and carry, as a liability, actuarially determined reserves to meet our obligations for future policy benefits and claims. These reserves do not represent an exact calculation of our future benefit liabilities but instead are estimates based on assumptions, which can be materially affected by changes in the 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.

• 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.

• Catastrophe 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, which could have a material adverse effect on our business, financial position, results of operations or cash flows.

• Catastrophe losses from terrorism or other factors could have an adverse effect on us—An occurrence of a significant catastrophic event, including terrorism, natural 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 investments with higher perceived returns. This process, referred to as disintermediation, may lead to net 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 or low interest rates—During periods of declining or low 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, actual 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 or low interest rates. A factor in pricing our insurance products is prevailing interest rates. Longer duration claims and premium rate guarantees 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—available-for-sale (“fixed maturity securities”), commercial mortgage loans and real estate. The fair values of our investments vary with changing economic and market

71

conditions and interest rates. In addition, we are subject to default risk on our fixed maturity securities portfolio and its corresponding impact on credit spreads. Our commercial mortgage loan portfolio is subject to delinquency, default and borrower concentration risks. Related declines in market activity due to overall declining values of fixed maturity securities may result in our fixed maturity securities portfolio becoming less liquid. Also, our commercial mortgage loans are relatively illiquid and the demand for our real estate owned may remain low due to macroeconomic conditions. We may have difficulty selling our fixed maturity securities, commercial mortgage loans and real estate owned 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 by competition, which in turn could have a material adverse effect on our business, financial position, results of operations or cash flows.

• A downgrade in our financial strength ratings may negatively affect our business—Financial strength ratings, which are an indicator of 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 regularly review the financial performance and condition of insurance companies, including our company. A ratings downgrade could increase our surrender levels for our annuity products, could adversely affect our ability to market our products, could increase costs of future debt issuances, and could 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 regulation and supervision throughout the United States (“U.S.”) including rules and regulations relating to income taxes and accounting principles generally accepted in the U.S. 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 deferred tax asset includes net operating losses which depend on future taxable income to be realized and may be limited or impaired by future ownership changes—Our deferred tax assets include federal, state and local net operating losses. Certain of our subsidiaries as a group have generated losses in recent years. Net operating losses can be available to reduce income taxes that might otherwise be incurred on future taxable income. There can be no assurance that we will generate the future taxable income necessary to utilize our net operating losses. Furthermore, the availability of these losses to be utilized in the future can become limited if certain changes in company structure or income levels occur. In such a circumstance, we may be unable to utilize the losses even in the event the company generates future taxable income.

• 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 or 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.

• Certain concentrations in our commercial mortgage loan investments may subject us to losses resulting from an economic downturn—While isolated to a small number of borrowers, the concentration of our commercial mortgage loan portfolio assets by individual borrower may expose us to potential losses resulting from an economic downturn. Although we diversify our commercial mortgage loan portfolio by location, type of property and individual borrower, 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.

• The concentration of our investments in California may subject us to losses resulting from the economic downturn—Our commercial mortgage loans are concentrated in the western region of the U.S., particularly in California. Currently, our California exposure is primarily in Los Angeles County, Orange County, San Diego County and the Bay Area Counties. We have a smaller concentration of commercial mortgage loans in the Inland Empire and the San Joaquin Valley where there has been greater economic decline. A continued decline in economic conditions in California could have a material adverse effect on our business, financial position, results of operations or cash flows.

• The concentration of our investments in the western region of the U.S. may subject us to losses resulting from certain natural catastrophes in this area—Due to our commercial mortgage loan concentration in the western region of the U.S., particularly in California, we are exposed to potential losses resulting from certain natural catastrophes, such as earthquakes and fires, which may affect the region. Although we diversify our commercial mortgage loan portfolio within the western region 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 or deeds in lieu of foreclosure to real estate collateralizing delinquent commercial mortgage loans held by us. Compliance costs associated with environmental laws and regulations or any remediation of affected properties could have a material adverse effect on our results of operations or financial condition.

72

• 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 as well as for the subsidiaries that comprise our Other category and do not have any significant operations of our own. Dividends and permitted payments from our subsidiaries are our principal source of cash to pay dividends to shareholders, make payments on debt securities and meet our other obligations. As a result, our ability to pay dividends to shareholders and interest payments on debt securities will primarily 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 in excess of certain statutory limitations. Oregon law requires us to receive the prior approval of the Oregon Insurance Division to pay such a dividend. See Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capital Management—Dividends from Standard.”

• Our ability to refinance debt and raise capital in future years depends not only on contributions from our subsidiaries but also on market conditions and availability of credit in the market—Our 10-year senior notes of $250 million will mature in October 2012. Should market conditions and credit availability worsen, we could be required to consider alternative means of raising replacement capital for our senior notes.

• Our portfolio of investments, including U.S. government and agency bonds and U.S. state and political subdivision bonds could be negatively impacted by U.S. credit and financial market conditions—A potential ratings downgrade of U.S. government securities could lead to future deterioration in the U.S. and global credit and financial markets. As a result, these events may materially adversely affect our business, financial condition and results of operations.

• Our business continues to be affected by employment and wage levels—Factors influencing the growth of our group insurance and retirement plans businesses include the employment levels, benefit offerings, and salary and wage growth of our employer groups. Current economic conditions have caused our employer groups to experience lower levels of insured employees, to limit benefit offerings, to reduce work hours, or to reduce or slow the growth of wage levels. If economic conditions worsen, it could have a material adverse effect on premium levels for our group businesses and revenues for our retirement plans business.

• Our profitability may be adversely affected by declining equity markets—U.S. and global equity markets heavily influence the value of our retirement plan assets under administration, which are a significant component from which our administrative fee revenues are derived. 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 revenues derived from the value of those assets.

• Declining equity markets and low interest rates could affect the funding status of Company sponsored pension plans—Our estimates of liabilities and expenses for pension and other postretirement benefits incorporate significant assumptions including the rate used to discount the estimated future liability, the long-term rate of return on plan assets and the employee work force. Declines in the discount rate or the rate of return on plan assets resulting from the current economic downturn could increase our required cash contributions or pension-related expenses in future periods. The funding status of the Company’s pension plans is evaluated annually during the fourth quarter.

• Our ability to conduct business may be compromised if we are unable to maintain the availability of our systems and safeguard the security of our data in the event of a disaster or other unanticipated events—We use computer systems to store, retrieve, evaluate and utilize customer and company data and information. Our business is highly dependent on our ability to access these systems to perform necessary business functions. System failures, system outages, outsourcing risk or the failure or unwillingness of a service provider to perform could compromise our ability to perform these functions in a timely manner and could hurt our relationships with our business partners and customers. In the event of a disaster such as a natural catastrophe, fire, a blackout, a computer virus, a terrorist attack or war, these systems may be inaccessible to our employees, customers or business partners for an extended period of time. These systems could also be subject to physical and electronic break-ins and subject to similar disruptions from unauthorized tampering. This may impede or interrupt our business operations and could have a material adverse effect on our business, financial position, results of operations or cash flows.

• The U.S. economic downturn and disruption in global financial markets could continue to adversely affect us in the near term—The U.S. economic downturn and disruption in the global financial market present risks and uncertainties. In the current economic downturn, we face the following risks:

• Declines in revenues or profitability as a result of lost wages or lower levels of insured employees by our customers due to reductions in workforce.

• Increases in pricing pressure and competition resulting in a loss of customers or new business as customers seek to reduce benefit costs and competitors seek to protect market share.

73

• Increases in commercial mortgage loan foreclosures.

• Increases in holdings of real estate owned properties due to a decline in demand for these properties and the decline in value of these properties during our holding period.

• Continued pressure on budgets for public institutions could impact our customer groups in this sector, which represents a significant customer group for our employee benefits business.

• If the U.S. economy and global financial markets do not continue to recover, it could have a lasting adverse effect on us—In addition to the risks we noted above that we are currently facing, if the U.S. economy and global financial markets do not continue to recover, we could be adversely affected in the following ways:

• Increases in corporate tax rates to finance government-spending programs.

• Reductions in the number of our potential lenders or to our committed credit availability due to combinations or failures of financial institutions.

• Loss of employer groups due to business acquisitions, bankruptcy or failure.

• Declines in the financial health of reinsurers.

• Reduction in the value of our general account investment portfolio.

• Declines in revenues and profitability as a result of lower levels of assets under administration.

• Continued pressure on budgets for public institutions could impact our customer groups in this sector, which represents a significant customer group for our employee benefits business.

On May 16, 2011, our Board of Directors authorized an additional 3.0 million shares of StanCorp common stock for its share repurchase program. The May 2011 authorization took effect upon the expiration of the February 2010 authorization and expires on December 31, 2012. Share repurchases under the repurchase program are made in the open market or in negotiated transactions in compliance with the safe harbor provisions of Rule 10b-18 under regulations of the Securities Exchange Act of 1934 (“Exchange Act”). Execution of the share repurchase program is based upon management’s assessment of market conditions for its common stock, capital levels, our assessment of the overall economy and other potential growth opportunities or priorities for capital use. Repurchases are made at market prices on the transaction date. We will evaluate share repurchases opportunistically based on equity markets, capital levels and our assessment of the direction of the overall economy.

The declaration and payment of dividends would be restricted if StanCorp elects to defer interest payments on its junior subordinated debentures. If the Company elected to defer interest payments, the dividend restriction would be in place during the interest deferral period, which cannot exceed five years.

Exhibit 3.1

ARTICLES OF INCORPORATION

OF

STANCORP FINANCIAL GROUP, INC.

(as amended as of October 10, 2011)

The following version of the Articles of Incorporation has been prepared for filing with the Securities and Exchange Commission, and includes all amendments reflected in Articles of Amendment filed with the Oregon Secretary of State through October 10, 2011.

ARTICLE 1

Name

The name of the Corporation is StanCorp Financial Group, Inc.

ARTICLE 2

Capital Stock

A. The Corporation is authorized to issue a total of Four Hundred Million (400,000,000) shares, consisting of Three Hundred Million (300,000,000) shares of Common Stock and One Hundred Million (100,000,000) shares of Preferred Stock.

B. Holders of Common Stock are entitled to one vote per share. On dissolution of the Corporation, after any preferential amount with respect to the Preferred Stock has been paid or set aside, the holders of Common Stock and the holders of any series of Preferred Stock entitled to participate in the distribution of assets are entitled to receive the net assets of the Corporation.

C. The Board of Directors is authorized, subject to limitations prescribed by the Oregon Business Corporation Act, as amended from time to time (the “Act”), and by the provisions of this Article, to provide for the issuance of shares of Preferred Stock in series, to establish from time to time the number of shares to be included in each series and to determine the designations, relative rights, preferences and limitations of the shares of each series. The authority of the Board of Directors with respect to each series includes determination of the following:

(1) The number of shares in and the distinguishing designation of that series;

(2) Whether shares of that series shall have full, special, conditional, limited or no voting rights, except to the extent otherwise provided by the Act;

(3) Whether shares of that series shall be convertible and the terms and conditions of the conversion, including provision for adjustment of the conversion rate in circumstances determined by the Board of Directors;

(4) Whether shares of that series shall be redeemable and the terms and conditions of redemption, including the date or dates upon or after which they shall be redeemable and the amount per share payable in case of redemption, which amount may vary under different conditions or at different redemption dates;

(5) The dividend rate, if any, on shares of that series, the manner of calculating any dividends and the preferences of any dividends;

(6) The rights of shares of that series in the event of voluntary or involuntary dissolution of the Corporation and the rights of priority of that series relative to the Common Stock and any other series of Preferred Stock on the distribution of assets on dissolution; and

(7) Any other rights, preferences and limitations of that series that are permitted by law to vary.

D. Series A Preferred Stock.

(1) Designation and Amount. The shares of such series shall be designated as “Series A Preferred Shares” and the number of shares constituting such series shall be 500,000.

(2) Dividends and Distributions.

(i) The holders of shares of Series A Preferred Shares shall be entitled to receive, when and as declared by the Board of Directors, out of funds legally available for the purpose, dividends in an amount per share equal to 100 (the “Adjustment Number”) multiplied by the aggregate per share amount of all cash dividends, and the Adjustment Number multiplied by the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions other than a dividend payable in Common Stock or a subdivision of the outstanding Common Stock (by reclassification or otherwise), declared on the Common Stock of the Corporation (the “Common Stock”) after the first issuance of any share or fraction of a share of Series A Preferred Shares.

(ii) The Corporation shall declare a dividend or distribution on the Series A Preferred Shares as provided in subparagraph 2(i) at the same time that it declares a dividend or distribution on the Common Stock (other than a dividend payable in Common Stock).

(iii) Dividends shall not be cumulative. Unpaid dividends shall not bear interest. Dividends paid on the Series A Preferred Shares in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding.

(3) Voting Rights. The holders of Series A Preferred Shares shall have the following voting rights:

(i) Each Series A Preferred Share shall entitle the holder thereof to the number of votes equal to the Adjustment Number then in effect on all matters submitted to a vote of the shareholders of the Corporation.

(ii) Except as otherwise provided herein or by law, the holders of Series A Preferred Shares and the holders of Common Stock shall vote together as one class on all matters submitted to a vote of shareholders of the Corporation.

(4) Certain Restrictions.

(i) Whenever dividends or distributions payable on the Series A Preferred Shares as provided in subparagraph 2 have not been declared or paid for any fiscal year, until all such dividends and distributions for such fiscal year on Series A Preferred Shares outstanding shall have been declared and paid in full, the Corporation shall not in such fiscal year:

(a) declare or pay dividends on or make any other distributions on any shares of stock ranking junior or on a parity (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Shares except dividends paid ratably on the Series A Preferred Shares and all such parity stock on which dividends are payable in proportion to the total amounts to which the holders of all such shares are then entitled and, dividends or distributions payable in Common Stock;

(b) purchase or otherwise acquire for consideration any Series A Preferred Shares or any shares of stock ranking on a parity with the Series A Preferred Shares, except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of such shares upon such terms as the Board of Directors, after consideration of the respective dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes.

(ii) The Corporation shall not permit any subsidiary of the Corporation to purchase or otherwise acquire for consideration any shares of stock of the Corporation unless the Corporation could, under subparagraph 4(i), purchase or otherwise acquire such shares at such time and in such manner.

(5) Restriction on Issuance of Shares; Reacquired Shares. The Corporation shall not issue any Series A Preferred Shares except upon exercise of rights (the “Rights”) issued pursuant to the Rights Agreement dated as of April 20, 2009, between the Corporation and Mellon Investor Services, LLC, (the “Rights Agreement”), a copy of which is on file with the secretary of the Corporation at its principal executive office and shall be made available to shareholders of record without charge upon written request. Any Series A Preferred Shares purchased or otherwise acquired by the Corporation in any manner whatsoever may be restored to the status of authorized but unissued shares after the acquisition thereof. All such shares shall upon any such restoration become authorized but unissued shares of Preferred Shares and may be reissued as part of a new series of Preferred Shares to be created by the Board of Directors, subject to the conditions and restrictions on issuance set forth herein.

(6) Liquidation, Dissolution or Winding Up.

(i) Upon any liquidation (voluntary or otherwise), dissolution or winding up of the Corporation, no distribution shall be made to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Preferred Shares unless, prior thereto, the holders of shares of Series A Preferred Shares shall have received the Adjustment Number multiplied by the per share amount to be distributed to holders of Common Stock, plus an amount equal to declared and unpaid dividends and distributions thereon to the date of such payment (the “Series A Liquidation Preference”). Following the payment of the full amount of the Series A Liquidation Preference, no additional distributions shall be made to the holders of shares of Series A Preferred Shares.

(ii) In the event that there are not sufficient assets available to permit payment in full of the Series A Liquidation Preference and the liquidation preferences of all other series of Preferred Shares, if any, which rank senior to or on a parity with the Series A Preferred Shares, then assets shall be distributed first to holders of any series of Preferred Shares ranking senior to the Series A Preferred Shares to the extent of their liquidation preferences and such remaining assets shall be distributed ratably to the holders of Series A Preferred Shares and such parity shares in proportion to their respective liquidation preferences.

(7) Consolidation, Merger, etc. In case the Corporation shall enter into any consolidation, merger, combination or other transaction in which the Common Stock is exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case the Series A Preferred Shares shall at the same time be similarly exchanged or changed in an amount per share equal to the Adjustment Number multiplied by the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each common Share is changed or exchanged.

(8) Anti-Dilution Adjustments to Adjustment Number. In the event the Corporation shall at any time after April 20, 2009 (the “Rights Declaration Date”) (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the Adjustment Number for all purposes of this Article 2 shall be adjusted by multiplying the Adjustment Number then in effect by a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Common Stock that were outstanding immediately prior to such event. In the event the Corporation shall at any time after the Rights Declaration Date, fix a record date for the issuance of rights, options or warrants to all holders of Common Stock entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Common Stock or securities convertible into Common Stock at a price per Common Stock (or having a conversion price per share, if a security convertible into Common Stock) less than the then Current Per Share Market Price of the Common Stock (as defined in Section 11(d) of the Rights Agreement) on such record date, then in each such case the Adjustment Number for all purposes of this Article 2 shall be adjusted by multiplying the Adjustment Number then in effect by, a fraction, the numerator of which shall be the number of shares of Common Stock outstanding on such record date plus the number of additional shares of Common Stock to be offered for subscription or purchase (or into which the convertible securities so to be offered are initially convertible) and the denominator of which shall be the number of shares of Common Stock outstanding on such record date plus the number of shares of Common Stock which the aggregate offering price of the total number of shares of Common Stock so to be offered (and/or the aggregate initial conversion price of the convertible securities so to be offered) would purchase at such Current Per Share Market Price (as defined in Section 11(d) of the Rights Agreement). In case such subscription price may be paid in a consideration part or all of which shall be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors. Common Stock owned by or held for the account of the Corporation shall not be deemed outstanding for the purpose of any such computation. Such adjustment shall be made successively whenever such a record date is fixed. In the event that such rights, options or warrants are not so issued, the Adjustment Number shall be readjusted as if such record date had not been fixed; and to the extent such rights, options or warrants are issued but not exercised prior to their expiration, the Adjustment Number shall be readjusted to be the number which would have resulted from the adjustment provided for in this paragraph 8 if only the rights, options or warrants that were exercised had been issued.

(9) No Redemption. The Series A Preferred Shares shall not be redeemable at the option of the Corporation or any holder thereof. Notwithstanding the foregoing sentence, the Corporation may acquire Series A Preferred Shares in any other manner permitted by law.

(10) Amendment. Subsequent to the Distribution Date (as defined in the Rights Agreement) these Articles of Incorporation shall not be further amended in any manner which would materially alter or change the

preferences, limitations and relative rights of the Series A Preferred Shares so as to affect them adversely without the affirmative vote of the holders of a majority of the outstanding Series A Preferred shares, voting separately as a class.

(11) Fractional Shares. Series A Preferred Shares may be issued in fractions of a share in integral multiples of one one-hundredth of a share, which shall entitle the holder, in proportion to such holders fractional shares, to exercise voting rights, receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series A Preferred Shares.

ARTICLE 3

Number and Tenure of Directors

A. The initial number of directors of the Corporation shall be not less than three (3). At such time as the Corporation has more than one shareholder the number of directors of the Corporation shall be not less than nine (9) nor more than twenty-one (21), and within such limits the exact number shall be fixed and increased or decreased from time to time by resolution of the Board of Directors. At such time as the number of directors is first increased to nine or more, the directors shall be divided into three classes, as nearly equal in number as possible, with the term of office of the first class (“Class I”) to expire at the first annual meeting of shareholders, the term of office of the second class (“Class II”) to expire at the second annual meeting of shareholders following the classification and the term of office of the third class (“Class III”) to expire at the third annual meeting of shareholders following the classification. At each annual meeting of shareholders following such initial classification and election, directors elected to succeed those directors whose terms expire shall be elected to serve three-year terms and until their successors are elected and qualified, so that the term of one class of directors will expire each year. When the number of directors is changed within the limits provided herein, any newly created directorships, or any decrease in directorships, shall be so apportioned among the classes as to make all classes as nearly equal as possible, provided that no decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

B. Directors of the Company may be removed only for cause at a meeting of shareholders called expressly for that purpose.

C. Any vacancy on the Board of Directors, including a vacancy resulting from an increase in the number of directors, may be filled by the Board of Directors, the remaining directors if less than a quorum (by the vote of a majority thereof) or by a sole remaining director. If the vacancy is not so filled, it shall be filled by the shareholders at the next annual meeting of shareholders. A vacancy that will occur at a specified later date, by reason of a resignation or otherwise, may be filled before the vacancy occurs, but the new director may not take office until the vacancy occurs.

D. This Article 3 may not be amended, altered, changed or repealed unless the amendment is approved by the vote of holders of 70 percent of the shares then entitled to vote at an election of directors.

ARTICLE 4

Amendment of Bylaws

Both the Board of Directors and the shareholders shall have the power to alter, amend or repeal the Bylaws of the Corporation. Any repeal or change of the Bylaws by the shareholders shall require the affirmative vote of not less than 70 percent of the votes entitled to be cast on the matter. This Article 4 may not be amended, altered, changed or repealed unless the amendment is approved by the vote of holders of 70 percent of the shares then entitled to vote at an election of directors.

ARTICLE 5

No Personal Liability

No director of the Corporation shall be personally liable to the Corporation or its shareholders for monetary damages for conduct as a director; provided that this Article shall not eliminate the liability of a director for any act or omission for which such elimination of liability is not permitted under the Oregon Business Corporation Act. No amendment to the Oregon Business Corporation Act that further limits the acts or omissions for which elimination of liability is permitted shall affect the liability of a director for any act or omission which occurs prior to the effective date of such amendment.

ARTICLE 6

Indemnification

The Corporation may indemnify to the fullest extent permitted by law any person who is made, or threatened to be made, a party to an action, suit or proceeding, whether civil, criminal, administrative, investigative, or otherwise (including an action, suit or proceeding by or in the right of the Corporation) by reason of the fact that the person is or was a director, officer or employee of the Corporation or a fiduciary within the meaning of the Employee Retirement Income Security Act of 1974 with respect to any employee benefit plan of the Corporation, or serves or served at the request of the Corporation as a director, officer or employee, or as a fiduciary of an employee benefit plan, of another Corporation, partnership, joint venture, trust or other enterprise. This Article shall not be deemed exclusive of any other provisions for indemnification of directors, officers and fiduciaries that may be included in any statute, bylaw, agreement, resolution of shareholders or directors or otherwise, both as to action in any official capacity and action in another capacity while holding office.

ARTICLE 7

Fair Price Provision

A. Whether or not a vote of stockholders is otherwise required, the vote of the holders of not less than 70 percent of the outstanding shares of “Voting Stock” (as hereinafter defined) of the Corporation shall be required for the approval or authorization of any “Business Combination” (as hereinafter defined) with any “Substantial Shareholder” (as hereinafter defined) or any Business Combination in which a Substantial Shareholder has an interest (except proportionately as a stockholder of the Corporation); provided, however, that the 70 percent voting requirement shall not be applicable if either:

(1) The “Continuing Directors” (as hereinafter defined) of the Corporation by at least a two-thirds vote (a) have expressly approved in advance the acquisition of the outstanding shares of Voting Stock that caused such Substantial Shareholder to become a Substantial Shareholder, or (b) have expressly approved such Business Combination; or

(2) The cash or fair market value (as determined by at least a majority of the Continuing Directors) of the property, securities or other consideration to be received per share by holders of Voting Stock of the Corporation (other than the Substantial Shareholder) in the Business Combination is not less than the “Highest Per Share Price” or the “Highest Equivalent Price” (as those terms are hereinafter defined) paid by the Substantial Shareholder involved in the Business Combination in acquiring any of its holdings of the Corporation’s Voting Stock acquired in the last two years.

B. For purposes of this Article 7:

(1) The term “Business Combination” shall include, without limitation, (a) any merger, exchange or consolidation of the Corporation, or any entity controlled by or under common control with the Corporation, with or into any Substantial Shareholder, or any entity controlled by or under common control with such Substantial Shareholder, (b) any merger, exchange or consolidation of a Substantial Shareholder, or any entity controlled by or under common control with such Substantial Shareholder, with or into the Corporation or any entity controlled by or under common control with the Corporation, (c) any sale, lease, exchange, transfer or other disposition (in one transaction or a series of transactions), including without limitation a mortgage or any other security device, of all or any “Substantial Part” (as hereinafter defined) of the property and assets of the Corporation, or any entity controlled by or under common control with the Corporation, to a Substantial Shareholder, or any entity controlled by or under common control with such Substantial Shareholder, (d) any purchase, lease, exchange, transfer or other acquisition (in one transaction or a series of transactions), including without limitation a mortgage or any other security device, of all or any Substantial Part of the property and assets of a Substantial Shareholder or any entity controlled by or under common control with such Substantial Shareholder, by the Corporation, or any entity controlled by or under common control with the Corporation, (e) any recapitalization of the Corporation that would have the effect of increasing the voting power of a Substantial Shareholder, (f) the issuance, sale, exchange or other disposition of any securities of the Corporation, or of any entity controlled by or under common control with the Corporation, by the Corporation or by any entity controlled by or under common control with the Corporation, (g) any liquidation, spinoff, splitoff, splitup or dissolution of the Corporation, and (h) any agreement, contract or other arrangement providing for any of the transactions described in this definition of Business Combination.

(2) The term “Substantial Shareholder” shall mean and include (a) any “Person” (as that term is defined in Section 2(2) of the Securities Act of 1933, as in effect on the date these Articles of Incorporation become effective (the “Effective Date”)) which, together with its “Affiliates” (as hereinafter defined) and “Associates” (as hereinafter defined), “Beneficially Owns” (as defined in Rule 13d-3 of the General Rules and Regulations under the Securities Exchange Act of 1934 as in effect on the Effective Date) in the aggregate 15 percent or more of the outstanding Voting Stock of the Corporation, and (b) any Affiliate or Associate (other than the Corporation or a wholly owned subsidiary of the Corporation) of any such Person. Two or more Persons acting in concert for the purpose of acquiring, holding or disposing of Voting Stock of the Corporation shall be deemed a “Person.”

(3) Without limitation, any share of Voting Stock of the Corporation that any Substantial Shareholder has the right to acquire at any time (notwithstanding that Rule 13d-3 deems such shares to be beneficially owned if such right may be exercised within 60 days) pursuant to any agreement, contract, arrangement or understanding, or upon exercise of conversion rights, warrants or options, or otherwise, shall be deemed to be Beneficially Owned by such Substantial Shareholder and to be outstanding for purposes of subparagraph B(2) above.

With respect to the shares owned by Affiliates, Associates or other Persons whose ownership is attributed to a Substantial Shareholder under the foregoing definition of Substantial Shareholder, if the price paid by such Substantial Shareholder for such shares is not determinable by a majority of the Continuing Directors, the price so paid shall be deemed to be the higher of (a) the price paid upon the acquisition thereof by the Affiliate, Associate or other Person or (b) the market price of the shares in question at the time when such Substantial Shareholder became the Beneficial Owner thereof.

(8) The terms “Highest Per Share Price” and “Highest Equivalent Price” as used in this Article shall mean the following: If there is only one class of capital stock of the Corporation issued and outstanding, the Highest Per Share Price shall mean the highest price that can be determined to have been paid at any time by the Substantial Shareholder involved in the Business Combination for any share or shares of that class of capital stock. If there is more than one class of capital stock of the Corporation issued and outstanding, the Highest Equivalent Price shall mean, with respect to each class and series of capital stock of the Corporation, the amount determined by a majority of the Continuing Directors, on whatever basis they believe is appropriate, to be the highest per share price equivalent to the highest price that can be determined to have been paid at any time by the Substantial Shareholder for any share or shares of any class or series of capital stock of the Corporation. The Highest Per Share Price and the Highest Equivalent Price shall include any brokerage commissions, transfer taxes and soliciting dealers’ fees paid by a Substantial Shareholder with respect to the shares of capital stock of the Corporation acquired by such Substantial Shareholder. In the case of any Business Combination with a Substantial Shareholder, the Continuing Directors shall determine the Highest Per Share Price or the Highest Equivalent Price for each class and series of the capital stock of the Corporation. The Highest Per Share Price and Highest Equivalent Price shall be appropriately adjusted to reflect the occurrence of any reclassification, recapitalization, stock split, reverse stock split or other readjustment in the number of outstanding shares of capital stock of the Corporation, or the declaration of a stock dividend thereon, between the last date upon which the Substantial Shareholder paid the Highest Per Share Price of Highest Equivalent Price and the effective date of the merger or consolidation or the date of distribution to stockholders of the Corporation of the proceeds from the sale of all or substantially all of the assets of the Corporation.

(9) The term “Substantial Part” shall mean 15 percent or more of the fair market value of the total assets of the Person in question, as reflected on the most recent balance sheet of such Person existing at the time the stockholders of the Corporation would be required to approve or authorize the Business Combination involving the assets constituting any such Substantial Part.

D. The provisions set forth in this Article may not be amended, altered, changed . or repealed in any respect unless such action is approved by the affirmative vote of the holders of not less than a majority of the outstanding shares of Voting Stock of the Corporation at a meeting of the shareholders duly called for the consideration of such amendment, alteration, change or repeal; provided, however, that if there is a Substantial Shareholder who is not a Continuing Director, such action must also be approved by the affirmative vote of the holders of not less than 70 percent of the outstanding shares of Voting Stock.

STANCORP FINANCIAL GROUP, INC.

SHORT TERM INCENTIVE PLAN

1. PURPOSES. This Plan is intended to enable the Company to attract, retain, motivate and reward qualified executive officers and key employees by providing them with the opportunity to earn competitive annual cash bonus compensation directly linked to individual performance, business unit performance and overall Company performance. This Plan is also intended to qualify eligible portions of the compensation paid under the Plan as “performance-based compensation” within the meaning of Section 162(m), so as to exempt such eligible compensation from the deduction limits imposed by Section 162(m) and to make such eligible compensation deductible by the Company for Federal income tax purposes.

2. DEFINITIONS. The following words as used in this Plan have the meanings ascribed to each below:

(a) “162(m) Performance Goals” means one or more targeted levels of performance for a fiscal year with respect to one or more of the following objective measures with respect to the Company or any Business Unit: net income, earnings per share, net income or earnings per share excluding after-tax net capital gains, stock price increase, total shareholder return (stock price increase plus dividends), capital adequacy ratio, double leverage ratio, assets under management, portfolio return, return on equity, return on assets, return on net assets, return on capital, return on investment, economic value added, revenues, premium revenues, annualized new premiums, operating expenses, income before income taxes, earnings before interest, taxes, depreciation and amortization (EBITDA), non-premium earnings, net investment income and cash flows, or any of the foregoing before the effect of acquisitions, divestitures, accounting changes, and restructuring and special charges (determined according to criteria pre-established by the Committee). The portion of any cash bonus paid under the Plan based on achievement of 162(m) Performance Goals is intended to constitute “performance-based compensation” within the meaning of Section 162(m).

(b) “Award” means an annual cash incentive award granted in accordance with Section 4 of the Plan.

(c) “Board” means the Board of Directors of the Company

(d) “Business Unit” means any subsidiary, division, line of business or other unit of the Company.

(f) “Company” means StanCorp Financial Group, Inc.

(g) “Discretionary Bonus” means the portion of a Participant’s target bonus for any fiscal year (not to exceed 20% of the target bonus) that will be payable (up to the maximum bonus percentage thereof) in the discretion of the Committee and will not be subject to achievement of 162(m) Performance Goals or Other Performance Goals. The Discretionary Bonus will not constitute “performance-based compensation” within the meaning of Section 162(m).

(h) “Other Performance Goals” means one or more targeted levels of performance for a fiscal year addressing aspects of a Participant’s individual job performance or the performance of any Business Unit for which the Participant is responsible or to which the Participant contributes, as determined and established by the Committee in its discretion. Other Performance Goals may be either objectively or subjectively determinable. The portion of any cash bonus paid under the Plan based on achievement of Other Performance Goals will not constitute “performance-based compensation” within the meaning of Section 162(m).

(i) “Participant” means (i) each executive officer of the Company and (ii) each other key employee of the Company or a subsidiary, whom the Committee designates as a participant under the Plan.

3. ADMINISTRATION. The Committee will administer and interpret the Plan. In accordance with Section 4 of the Plan, the Committee will establish target bonuses and performance goals for the applicable year. In accordance with Section 5 of the Plan, the Committee will certify whether such performance goals have been met, and determine the amount of bonuses to be paid. The Committee’s determinations under the Plan will be final and conclusive.

4. TARGET BONUSES AND PERFORMANCE GOALS. To make an Award to any Participant for any fiscal year under the Plan, the Committee shall, no later than the 90th day of that fiscal year, establish in writing (i) a target cash bonus amount for the Participant for performance in that fiscal year, (ii) the percentage (e.g., 150%) of the target bonus that shall be the maximum bonus, (iii) the portion(s) of the target bonus that will be payable based on 162(m) Performance Goals and/or Other Performance Goals for the fiscal year, and the portion of the target bonus that shall be a Discretionary Bonus, (iv) the 162(m) Performance Goals and/or the Other Performance Goals for the fiscal year, and (v) the methodology for determining the bonus amounts to be paid based on the level of achievement of the 162(m) Performance Goals and/or the Other Performance Goals for the fiscal year. The Committee may, in its sole discretion, reserve the right to reduce the resulting cash bonus under any Award prior to payment on such terms as determined by the Committee. The terms of Awards shall be promptly communicated to Participants.

5. COMPUTATION AND CERTIFICATION OF BONUS. Following the conclusion of any fiscal year, prior to the payment of any cash bonuses under the Plan with respect to that year, the Committee shall certify in writing the levels of attainment of the 162(m) Performance Goals and the Other Performance Goals for the year, the amount of Discretionary Bonus determined by the Committee for each Participant, and the calculation of the total bonus amount for each Participant. No payment of bonus with respect to any portion of the target bonus

based on 162(m) Performance Goals or Other Performance Goals shall be paid if the related performance goal is not met. The Committee shall not exercise its discretion to pay any amount as a Discretionary Bonus in replacement for amounts not earned under the 162(m) Performance Goals. Bonuses shall be paid as soon as practicable following certification by the Committee, and no later than March 15 of the year following the year covered by the Award.

6. MAXIMUM BONUS. The maximum cash bonus that may be paid or accrued for any Participant with respect to performance of the Company in any fiscal year shall be $2,500,000.

7. GENERAL PROVISIONS.

(a) Effective Date. This Plan has been adopted by the Board and is effective beginning with Awards made to Participants for performance in the Company’s 2007 fiscal year, which shall be granted in the first 90 days of 2007. The Plan is subject to approval of the Company’s shareholders and was approved by shareholders at the 2007 Annual Meeting of Shareholders.

(b) Termination; Amendment. The Board may at any time amend or terminate the Plan, except that no amendment will be effective without approval by the Company’s shareholders if such approval is necessary to qualify amounts payable hereunder as “performance-based compensation” under Section 162(m). Unless it is re-approved by the shareholders, the Plan shall terminate on the date of the first shareholder meeting that occurs in the fifth year after the year in which the Plan was last approved or re-approved by shareholders. No termination of the Plan shall affect performance goals and related Awards established by the Committee prior to such termination.

(c) No Employment Rights. Nothing in this Plan will be construed as conferring upon any Participant any right to continue in the employment of the Company or any of its subsidiaries.

(d) Nonalienation of Benefits. Except as expressly provided herein or otherwise required by applicable law, no Participant or beneficiary will have the power or right to alienate, transfer, anticipate, sell, assign, pledge, attach, or otherwise encumber the Participant’s interest under the Plan.

(e) Withholding. Any Award payable to a Participant or a beneficiary under this Plan will be subject to any applicable Federal, state and local income and employment taxes and any other amounts that the Company or a subsidiary is required at law to deduct and withhold from such Award.

(f) Plan Unfunded. The entire cost of the Plan shall be paid from the general assets of the Company. The rights of any Participant or beneficiary to receive an Award under the Plan shall be only those of a general unsecured creditor, and neither the Company nor the Board or the Committee shall be responsible for the adequacy of the general assets of the Company to meet and discharge Plan liabilities.

(g) Severability. If any provision of this Plan is held unenforceable, the remainder of the Plan will continue in full force and effect without regard to such unenforceable provision and will be applied as though the unenforceable provision were not contained in the Plan.

(h) Governing Law. The Plan will be construed in accordance with and governed by the laws of the State of Oregon, without reference to the principles of conflict of laws.

(i) Headings. Headings are inserted in this Plan for convenience of reference only and are to be ignored in any construction of the provisions of the Plan.

Through its subsidiaries, StanCorp has the authority to underwrite insurance products in all 50 states. StanCorp operates through two segments: Insurance Services and Asset Management as well as an Other category. See “Note 5—Segments.”

StanCorp has the following wholly-owned operating subsidiaries: Standard Insurance Company (“Standard”), The Standard Life Insurance Company of New York, Standard Retirement Services, Inc. (“Standard Retirement Services”), StanCorp Equities, Inc. (“StanCorp Equities”), StanCorp Mortgage Investors, LLC (“StanCorp Mortgage Investors”), StanCorp Investment Advisers, Inc. (“StanCorp Investment Advisers”), StanCorp Real Estate, LLC (“StanCorp Real Estate”), Standard Management, Inc. (“Standard Management”) and Adaptu, LLC (“Adaptu”).

Adaptu provides an online service to help users plan and manage their financial lives.

Standard holds interests in low-income housing tax credit investments. These interests do not meet the requirements for consolidation under existing accounting standards, and thus the Company's interests in the low-income housing tax credit investments are accounted for under the equity method of accounting. The total investment in these interests was $181.8 million and $128.0 million at June 30,2012 and December 31, 2011, respectively.

In October 2010, the Financial Accounting Standards Board ('FASB') issued Accounting Standards Update ('ASU') No. 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts. ASU No. 2010-26 amends the codification guidance for insurance entities to eliminate the diversity of accounting treatment related to deferred acquisition costs ('DAC'). The Company has adopted this standard retrospectively as of January 1, 2012, and comparative financial statements of prior periods have been adjusted.

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. Intercompany balances and transactions have been eliminated on a consolidated basis. 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 June 30,2012, and for the results of operations for the three and six months endedJune 30,2012 and 2011, and cash flows for the six months endedJune 30,2012 and 2011. Interim results for the three and six months endedJune 30,2012 are not necessarily indicative of the results that may be expected for the year ending December 31,2012. This report should be read in conjunction with the Company's 2011 annual report on Form 10-K and the Company's current report on Form 8-K dated July 18, 2012 which updated certain items in the Company's annual report on Form 10-K for the retrospective adoption of ASU No. 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts.

Deferred Acquisition Costs ("DAC"), Value Of Business Acquired ("VOBA") And Other Intangible Assets

9.       DEFERRED ACQUISITION COSTS (“DAC”), VALUE OF BUSINESS ACQUIRED (“VOBA”) AND OTHER INTANGIBLE ASSETS

DAC, VOBA and other acquisition related 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 other intangible assets are subject to impairment tests on an annual basis or more frequently if circumstances indicate that carrying values may not be recoverable.

In October 2010, the FASB issued Accounting Standards Update ('ASU') No. 2010-26, Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts. ASU No. 2010-26 amends the codification guidance for insurance entities to eliminate the diversity of accounting treatment related to deferred acquisition costs. The Company adopted this standard retrospectivelyas of January 1, 2012, and comparative financial statements of prior periods have been adjusted.

The following table sets forth activity for DAC, VOBA and other intangible assets:

			Six Months Ended		Year Ended
			June 30, 2012		December 31, 2011
			(In millions)
Carrying value at beginning of period:
	DAC		$	274.4	$	250.1
	VOBA			26.4		28.4
	Other intangible assets			44.1		51.7
		Total balance at beginning of period		344.9		330.2

	DAC			38.4		81.7
		Total deferred or acquired		38.4		81.7

	DAC			(27.8)		(57.4)
	VOBA			(2.1)		(2.0)
	Other intangible assets			(3.0)		(7.6)
		Total amortized during period		(32.9)		(67.0)
Carrying value at end of period, net:
	DAC			285.0		274.4
	VOBA			24.3		26.4
	Other intangible assets			41.1		44.1
		Total carrying value at end of period	$	350.4	$	344.9

The Company defers certain acquisition costs that vary with and are directly related to the origination of 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. Changes in actual persistency are reflected in the calculated DAC balance. Costs that are not directly associated with the acquisition of new business are not deferred as DAC and are charged to expense as incurred. Generally, annual commissions are considered expenses and are not deferred.

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. The Company amortizes 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.

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. For the Company's individual deferred annuities, DAC is generally amortized over 30 years, though expected gross profits can fluctuate due to changes in the fair value of our S&P 500 Index options and index-based interest guarantees. DAC for group annuity products is amortized over 10 years.

VOBA primarily represents the discounted future profits of business assumed through reinsurance agreements. The Company has established VOBA for a block of individual disability business assumed from 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, 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 the Company's assumptions, the Company could be required to make adjustments to VOBA and related amortization. During the first six months of 2012, the Company recorded an $0.8 million impairment to VOBAdue to experience related to the block of claims assumed from TIAA.The Company did not record a similar impairment in the second quarter of 2012, or in the second quarter and first six months of 2011. The VOBA associated with the TIAA transaction is amortized in proportion to expected gross profits with an amortization period of up to 20 years. For the VOBA associated with the Minnesota Life block of business assumed, the amortization period is up to 30 years and is amortized in proportion to future premiums. The accumulated amortization of VOBA was $64.5 million and $62.4 million at June 30,2012 and December 31, 2011, respectively.

The following table sets forth the amount of DAC and VOBA balances amortized in proportion to expected gross profits and the percentage of the total balance of DAC and VOBA amortized in proportion to expected gross profits:

	June 30, 2012				December 31, 2011
	Amount		Percent		Amount		Percent
	(Dollars in millions)
DAC	$	64.4	22.6	%	$	60.7	22.1	%
VOBA		6.1	25.1			7.1	26.9

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

• Persistency.
• Interest rates, which affect both investment income and interest credited.
• Stock market performance.
• Capital gains and losses.
• Claim termination rates.
• Amount of business in force.

These assumptions are modified to reflect actual experience when appropriate. Although a change in a single assumption may have an impact on the calculated amortization of DAC or VOBA for balances associated with investment contracts, 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 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 generally occurs as a result of actual experience or future expectations differing from previous estimates. As a result of unlocking, the amortization schedule for future periods is also adjusted.

The following table sets forth the impact of unlocking on DAC and VOBA balances:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2012		2011		2012		2011
	(In millions)
Decrease to DAC and VOBA	$	0.3	$	0.6	$	1.1	$	0.6

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. However, future changes in DAC and VOBA balances due to changes in underlying assumptions are not expected to be material.

The Company's other intangible assets are subject to amortization and consist of certain customer lists from Asset Management business acquired and an individual disability marketing agreement. Customer lists have a combined estimated weighted-average remaining life of approximately 8.4years. 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 Minnesota Life marketing agreement will be fully amortized by the end of 2023. The accumulated amortization of other intangible assets was $33.6 million and $30.6 million at June 30,2012and December 31, 2011, respectively.

The following table sets forth the estimated net amortization of VOBA and other intangible assets for the remainder of 2012 and for each of the next five years:

Commitments And Contingencies

10.       COMMITMENTS AND CONTINGENCIES

Litigation Contingencies

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 atJune 30,2012. 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.

Senior Unsecured Revolving Credit Facility (“Facility”) Contingencies

On June 22, 2012, StanCorp entered into an agreementfor a four-year, $250 million Facility. Additionally, upon the request of StanCorp and with consent of the lenders under the Facility, the Facility canbe increased to $350 million. The termination date of the Facility is June 22, 2016, though, at the option of StanCorp andwith the consent of the lenders under the Facility, the termination date can be extended for two additional one year periods. Borrowings from the facility will be used to provide for the 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 two financial covenants that are based on the Company's ratio of total debt to total capitalization andconsolidated net worth. StanCorp is also subject to covenants that limit subsidiary indebtedness.The Facility is subject to performance pricing based upon the Company's publicly announced debt ratings and includes an interestrate option at the election of the borrower of a base rate plus the applicable margin or the LIBOR rate plus the applicable margin, plus facility and utilization fees. At June 30,2012, StanCorp was in compliance with all financial covenants under the Facility and had no outstanding balance on the Facility.

Effective upon the closing of the Facility,a prior credit agreement was terminated. This prior credit agreement was scheduled to terminate June 15, 2013.

Other Financing Obligations

The Company has $250 million of 6.875%, 10-year senior notes (“2012 Senior Notes”), which mature on October 1, 2012. The principal amount of the 2012 Senior Notes is payable at maturity and interest is payable semi-annually in April and October.Given the maturity date of the 2012 Senior Notes, they have been classified as short-term debt as of June 30, 2012.See “Note 13—Subsequent Events” for further discussion

The Company has $300 million of 6.90%, junior subordinated debentures (“Subordinated Debt”), which matures onJune 1, 2067, is non-callable at par for the first 10 years (prior to June 1, 2017). The principal amount of the Subordinated Debt is payable at final maturity. Interest ispayable semi-annually in June and December for the first 10 years up to June 1, 2017, and quarterly thereafter at a floatingrate equal to three-month LIBOR plus 2.51%. StanCorp has the option to defer interest payments for up to five years. Thedeclaration and payment of dividends to shareholders would be restricted if the Company elected to defer interestpayments on its Subordinated Debt. If elected, the restriction would be in place during the interest deferral period.StanCorp is currently not deferring interest on the Subordinated Debt.

In the normal course of business, the Company commits to fund commercial mortgage loans generally up to 90 days in advance. At June 30,2012, the Company had outstanding commitments to fund commercial mortgage loans totaling$161.9 million, with fixed interest rates ranging from 4.375% to 5.750%. 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, the Company will retain the commitment fee and good faith deposit. Alternatively, if the Company terminates 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.

Retirement Benefits

4. RETIREMENT BENEFITS

Pension 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 the Company, and the agent pension plan is for former field employees and agents. The defined benefit pension plans provide benefits based on years of service and final average pay. Both plans are sponsored by Standard and administered by Standard Retirement Services and are closed to new participants. Participation in the defined benefit pension plans is generally limited to eligible employees whose date of employment began before 2003.

Under the employee pension plan, a participant is entitled to a normal retirement benefit once the participant reaches age 65. A participant can also receive a normal, unreduced retirement benefit once the sum of his or her age plus years of service is at least 90.

The Company recognizes the funded status of the pension plans as an asset or liability on the balance sheet. The funded status is measured as the difference between the fair value of the plan assets and the projected benefit obligation as of the year-end balance sheet date. While the Company is not obligated to make any contributions to its pension plans for 2012, it does evaluate the funding status of these plans annually in the fourth quarter.

The following table sets forth the components of net periodic benefit cost and other changes in plan assets and benefit obligations recognized in other comprehensive income for pension benefits:

Postretirement Benefits Other Than Pensions

Standard sponsors and administers a postretirement benefit plan that includes medical and prescription drug benefits.A group term life insurance benefit was curtailed as of December 31, 2011. 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. Participation in the postretirement benefit plan is limited to employees who had reached the age of 40, or whose combined age and length of service was equal to or greater than 45 years as of January 1, 2006. This plan is closed to new participants.

The Company recognizes the funded status of the postretirement benefit plan as an asset or liability on the balance sheet. The funded status is measured as the difference between the fair value of the plan assets and the accumulated benefit obligation.

The following table sets forth the components of net periodic benefit cost and other amounts recognized in other comprehensive income for postretirement benefits:

Deferred Compensation Plans

Eligible employees are covered by a qualified deferred compensation plan sponsored by Standard 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 planwere $2.3 million and $2.7 million for the second quarters of2012 and 2011, respectively,and $5.4 million and $5.8 million for the first six months of2012 and 2011, respectively.

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 $10.3 million atJune 30,2012 and$10.7million at December 31, 2011.

Non-Qualified Supplemental Retirement Plan

Eligible executive officers are covered by a non-qualified supplemental retirement plan(“non-qualified plan”). Under the non-qualified plan, a participant is entitled to a normal retirement benefit once the participant reaches age 65. A participant can also receive a normal, unreduced retirement benefit once the sum of his or her age plus years of service is at least 90.The Company recognizes the unfunded status of the non-qualified plan in other liabilities on the balance sheet. The unfunded status was $28.8 million and $28.5 million at June 30,2012and December 31, 2011, respectively. Expenses were $0.7 million and $0.7millionforthe second quarters of2012 and 2011, respectively, and were $1.3million and $1.4 millionfor the first six months of2012 and 2011, respectively. The net loss and prior service cost, net of tax, excluded from the net periodic benefit cost and reported as a component of accumulated other comprehensive income was$5.4 million and $5.7 million at June 30,2012 and December 31, 2011, respectively.

Share-Based Compensation

3.       SHARE-BASED COMPENSATION

The Company has two active share-based compensation plans: the 2002 Stock Incentive Plan (“2002 Plan”) and the 1999 Employee Share Purchase Plan (“ESPP”). The 2002 Plan authorizes the Board of Directors to grant incentive or non-statutory stock options and stock awards to eligible employees and certain related parties. Of the 4.8 million shares of common stock authorized for the 2002 Plan,0.9 million shares or options for shares remain available for grant at June 30,2012. The Company's ESPP allows eligible employees to purchase StanCorp common stock at a discount. Of the 3.5 million shares authorized for the ESPP, 1.7 million shares remain available for issuance at June 30,2012.

The following table sets forth the total compensation cost and related income tax benefit under the Company's share-based compensation plans:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2012		2011		2012		2011
	(In millions)
Compensation cost	$	1.6	$	1.5	$	3.9	$	3.1
Related income tax benefit		0.5		0.5		1.3		1.1

The Company has provided three types of share-based compensation pursuant to the 2002 Plan: option grants, stock award grants and director stock grants.

Option Grants

Options are granted to officers and certain non-officer employees. Options are granted with an exercise price equal to the closing market price of StanCorp common stock on the grant date. Options generally vest in equal installments on the first four anniversaries of the vesting reference date.

The Company granted 225,133and 236,785 options for the first six months of2012 and 2011, respectively, at a weighted-average exercise price of $39.58 and $45.46, respectively. The fair value of each option award granted was estimated using the Black-Scholes option pricing model as of the grant date. The weighted-average grant date fair value of options grantedfor the first six months of2012 and 2011 was $14.44and $17.48, respectively.

The compensation cost of stock options is recognized over the vesting period, which is also the period over which the grantee must provide services to the Company. At June 30,2012, the total compensation cost related to unvested option awards that had not yet been recognized in the financial statements was $7.1 million. This compensation cost will be recognized over a weighted-average period of 2.7 years.

Stock Award Grants

The Company grants performance-based stock awards (“Performance Shares”) to designated senior officers. The payout for these awards is based on the Company's financial performance over a three-year period.Performance Share grants represent the maximum number of shares of StanCorp common stock issuable to the designatedsenior officers. The actual number of shares issued at the end of the performance period is based on satisfaction of employment and Company financial performance conditions, with a portion of the shares withheld to cover required tax withholding. Under the 2002Plan, the Company had 0.6 million shares available for issuance as stock award grants at June 30,2012.

The Company granted 179,818 and 116,978 Performance Shares for the first six months of2012 and 2011, respectively.

The Company issued 9,899and 4,906shares of StanCorp common stock for the first six months of2012 and 2011, respectively, to redeem Performance Shares that vested following the 2011 and 2010 performance periods, net of Performance Shareswithheld to cover the required taxes.

The fair value of the Performance Shares is determined based on the closing market price of StanCorp common stock on the grant date.

The compensation cost that the Company will ultimately recognize as a result of these stock awards is dependent on the Company's financial performance. Assuming that the maximum performance is achieved for each performance goal, $15.3 million in additional compensation cost would be recognized through 2014. Assuming that the target performance is achieved for each performance goal, $8.1 million in additional compensation cost would be recognized through 2014. Assuming that the maximum performance is achieved this cost is would be recognized over a weighted-average period of 1.8 years.

Director Stock Grants

Effective May 7, 2012, each director who is not an employee of the Company receives annual compensation of StanCorp common stock with a fair value equal to $100,000 based on the closing market price of StanCorp common stock on the day of the annual shareholders meeting.

The Company issued 9,489 and 10,399 shares of StanCorp common stock for the second quarters of2012 and 2011, respectively, related to the annual Director stock grant.

Employee Share Purchase Plan

The Company's ESPP allows eligible employees to purchase StanCorp common stock at a 15%discount of the lesser of the closing market price of StanCorp common stock on either the commencement date or the final date of each six-month offering period. 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.

ASU 2011-11, Disclosures about Offsetting Assets and Liabilities

In December 2011, the FASB issued ASU No. 2011-11, Disclosures about Offsetting Assets and Liabilities. The main objective of ASU No. 2011-11 is to enhance disclosures for financial instruments and derivative instruments which have right of setoff conditions. Under the guidance provided in this ASU, entities would be required to disclose the amounts offset in determining the net amounts presented in their statement of financial position. The amount of both the recognized asset and the recognized liability subject to offset under the same arrangement will become a required disclosure.

ASU No. 2011-11 is effective for interim and annual periods beginning on or after January 1, 2013. The Company does not currently have exposure to hedges, derivatives or master netting arrangements that would be subjected to these additional disclosures. Therefore, the Company does not expect this ASU to have a material effect on its asset and liability disclosures in the financial statements.

Gross Unrealized Losses

The following tables set forth the gross unrealized losses and fair value of investments, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position:

			June 30, 2012
			Total				Less than 12 months				12 or more months
			Number		Amount		Number		Amount		Number		Amount
			(Dollars in millions)
Unrealized losses:
		Corporate bonds		201	$	6.9		182	$	4.2		19	$	2.7
Fair market value of securities with
	unrealized losses:
		Corporate bonds		201	$	227.9		182	$	197.9		19	$	30.0

			December 31, 2011
			Total				Less than 12 months				12 or more months

Fair market value of securities with
	unrealized losses:
		Corporate bonds		360	$	425.3		334	$	398.0		26	$	27.3

The unrealized losses on the investment securities set forth above were primarily due to increases in market interest rates subsequent to their purchase by the Company. Additionally, unrealized losses have been affected by overall economic factors. The Company expects the fair value of these investment securities to recover as the investment securities approach their maturity dates or sooner if market yields for such investment securities decline. The Company does not believe that any of the investment securities are impaired due to credit quality or due to any company or industry specific event. Based on management's evaluation of the securities and the Company's intent to hold the securities, and as it is unlikely that the Company will be required to sell the securities, none of the unrealized losses summarized in this table are considered other-than-temporary.

Commercial Mortgage Loans

The Company underwrites mortgage loans on commercial property throughout the United States. In addition to real estate collateral, the Company requires either partial or full recourse on most loans. At June 30,2012, the Company did not have any direct exposure to sub-prime or Alt-A mortgages in its commercial mortgage loan portfolio.

The following table sets forth the commercial mortgage loan portfolio by property type, by geographic region within the U.S. and by U.S. state:

*        Geographic regions obtained from the American Council of Life Insurers Mortgage Loan Portfolio Profile.

Through its concentration of commercial mortgage loans in California, the Company is exposed to potential losses from an economic downturn in California as well as certain catastrophes, such as earthquakes and fires that may affect certain areas of the western region. Borrowers are required to maintain fire insurance coverage to provide reimbursement for any losses due to fire. Management diversifies the 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 the California-based commercial mortgage loans has been substantially below the industry average and consistent with the Company's experience in other states. The Company does not require earthquake insurance for the properties when it underwrites new loans. However, management does consider the potential for earthquake loss based upon seismic surveys and structural information specific to each property. The Company does not expect a catastrophe or earthquake damage in the western region to have a material adverse effect on its business, financial position, results of operations or cash flows. Currently, the Company's California exposure is primarily in Los Angeles County, Orange County, San Diego County and the Bay Area Counties. There is a smaller concentration of commercial mortgage loans in the Inland Empire and the San Joaquin Valley where there has been greater economic decline. Due to the concentration of commercial mortgage loans in California, a continued economic decline in California could have a material adverse effect on the Company's business, financial position, results of operations or cash flows.

The carrying value of commercial mortgage loans represents the outstanding principal balance less a loan loss allowance for probable uncollectible amounts. The commercial mortgage loan loss allowance is estimated based on evaluating known and inherent risks in the loan portfolio and consists of a general and a specific loan loss allowance.

Impairment Evaluation

The Company continuously monitors its commercial mortgage loan portfolio for potential nonperformance by evaluating the portfolio and individual loans. Key factors that are monitored are as follows:

• Loan loss experience.
• Delinquency history.
• Debt coverage ratio.
• Loan to value ratio.
• Refinancing and restructuring history.
• Request for forbearance history.

  If the analysis above indicates a loan might be impaired, it is further analyzed for impairment through the consideration of the following additional factors:

• Delinquency status.
• Foreclosure status.
• Restructuring status.
• Borrower history.

If it is determined a loan is impaired, a specific allowance is recorded, if necessary.

General Loan Loss Allowance

The general loan loss allowance is based on the Company's analysis of factors including changes in the size and composition of the loan portfolio, debt coverage ratios, loan to value ratios, actual loan loss experience and individual loan analysis.

Specific Loan Loss Allowance

An impaired commercial mortgage loan is a loan that is not performing to the contractual terms of the loan agreement. A specific allowance for losses is recorded when a loan is considered to be impaired and it is probable that all amounts due will not be collected. The Company also holds specific loan loss allowances on certain performing commercial mortgage loans that it continues to monitor and evaluate. Impaired commercial mortgage loans without specific allowances for losses are those for which the Company has determined that it remains probable that all amounts due will be collected although the timing or nature may be outside the original contractual terms. In addition, for impaired commercial mortgage loans, the Company evaluates the cost to dispose of the underlying collateral, any significant out of pocket expenses the loan may incur and other quantitative information management has concerning the loan. Portions of loans that are deemed uncollectible are written off against the allowance, and recoveries, if any, are credited to the allowance.

The following table sets forth changes in the commercial mortgage loan loss allowance:

				Three Months Ended				Six Months Ended
				June 30,				June 30,
				2012		2011		2012		2011
				(In millions)
Commercial mortgage loan loss allowance:
	Beginning balance			$	45.6	$	39.4	$	48.1	$	36.1
		Provision			5.1		9.3		6.4		18.0
		Charge-offs, net			(5.1)		(5.2)		(8.9)		(10.6)
			Ending balance	$	45.6	$	43.5	$	45.6	$	43.5
	Specific loan loss allowance			$	24.6	$	26.5	$	24.6	$	26.5

			Total commercial mortgage loan loss allowance	$	45.6	$	43.5	$	45.6	$	43.5

The larger commercial mortgage loan loss allowance as of June 30,2012 compared to June 30,2011 was primarily due to the net increase in the general reserve during the second quarter and first six months of2012. The lower provision and charge-offs for the second quarter and first six months of2012 compared to the same periods of 2011 were primarily related to lower losses associated with foreclosures, accepted deeds in lieu of foreclosure on commercial mortgage loans and other related charges associated with commercial mortgage loans leaving the portfolio during the second quarter and first six months of2012.

The following table sets forth the recorded investment in commercial mortgage loans:

		June 30, 2012		December 31, 2011

Commercial mortgage loan loss allowance			(45.6)		(48.1)
	Total commercial mortgage loans	$	5,098.7	$	4,902.3

The Company assesses the credit quality of its commercial mortgage loan portfolio quarterly by reviewing the performance of its portfolio which includes evaluating its performing and nonperforming commercial mortgage loans. Nonperforming commercial mortgage loans include all commercial mortgage loans that are 60 days or more past due and commercial mortgage loans that are not 60 days past due but are not substantially performing to other original contractual terms.

The decreasein impaired commercial mortgage loans at June 30,2012 compared to December 31,2011 was primarily due to more loans in this category being paid off or being foreclosedon during the first six months of2012. As of June 30,2012and December 31,2011, the Company did not have any commercial mortgage loans greater than 90 days delinquent that were accruing interest.

A restructuring is considered to be a troubled debt restructuring when the debtor is experiencing financial difficulties and the restructured terms constitute a concession. The Company evaluates all restructured commercial mortgage loans for indications of troubled debt restructurings and the potential losses related to these restructurings. If a loan is considered a troubled debt restructuring, the Company impairs the loan and records a specific allowance for estimated losses. In some cases, the recorded investment in the loan may increase post-restructuring. As a result of adopting the amendments in ASU No. 2011-02, A Creditor's Determination of Whether a Restructuring Is a Troubled Debt Restructuring, the Company assessed all restructurings that occurred during the period for identification as troubled debt restructurings. The Company did not identify any troubled debt restructurings that were not already considered impaired.

The following table sets forth information related to the troubled debt restructurings of financing receivables:

Interest Income

The Company records interest income in net investment income and continues to recognize interest income on delinquent commercial mortgage loans until the loans are more than 90 days delinquent. Interest income and accrued interest receivable are reversed when a loan is put on non-accrual status. For loans that are less than 90 days delinquent, management may reverse interest income and the accrued interest receivable if there is a question on the collectability of the interest. Interest income on loans in the 90-day delinquent category is recognized in the period the cash is collected. The Company resumes the recognition of interest income when the loan becomes less than 90 days delinquent and management determines it is probable that the loan will remain performing.

The amount of interest income recognized on impaired commercial mortgage loans was $1.0million and $0.9 million for the second quarters of2012 and 2011, respectively and was $2.1 million for the first six months of2012 and 2011. The cash received by the Company in payment of interest on impaired commercial mortgage loans was $0.9 million and $0.7 million for the second quarters of2012 and 2011, respectively and was $2.0million and $1.4 million for the first six months of2012 and 2011, respectively.

The Company closely monitors all past due commercial mortgage loans; additional attention is given to those loans at least 60 days past due. Commercial mortgage loans that were at least 60 days past due totaled $15.8 million and $17.1 million at June 30, 2012 and December 31, 2011, respectively. The Company's current level of 60 days past due commercial mortgage loans is higher than its historical levels due to the current economic challenges. Overall, loans at least 60 dayspast due were 0.31% and 0.34% of the commercial mortgage loan portfolio at June 30, 2012 and December 31, 2011.

Segments

5. SEGMENTS

StanCorp operates through two reportable segments: Insurance Services and Asset Management, as well as an Other category. Subsidiaries, or operating segments, have been aggregated to form the Company's reportable 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 AD&D insurance, group dental and group vision insurance, and absence management services. The Asset Management segment offers full-service 401(k) plans, 403(b) plans, 457 plans, defined benefit plans, money purchase pension plans, profit sharing plans and non-qualified deferred compensation products and services. This segment also offers investment advisory and management services, financial planning services, commercial mortgage loan origination and servicing, individual fixed-rate annuity products, group annuity contracts and retirement plan trust products. The Other category includes return on capital not allocated to the product segments, holding company expenses, operations of certain unallocated subsidiaries, interest on debt, unallocated expenses, net capital gains and losses related to the impairment or the disposition of the Company's invested assets and adjustments made in consolidation.

Intersegment revenues are comprised of administrative fee revenues charged by the Asset Management segment to manage the fixed maturity securities—available-for-sale (“fixed maturity securities”) and commercial mortgage loan portfolios for the Company's insurance subsidiaries.

Fair Value

Fair Value

6.       FAIR VALUE

Assets and liabilities recorded at fair value are disclosed using a three-level hierarchy. 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 the Company's 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 the Company 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.

There are three types of valuation techniques used to measure assets and liabilities recorded at fair value:

• The market approach, which uses prices or other relevant information generated by market transactions involving identical or comparable assets or liabilities.
• The income approach, which uses the present value of cash flows or earnings.
• The cost approach, which uses replacement costs more readily adaptable for valuing physical assets.

       The Company uses both the market and income approach in its fair value measurements. These measurements are discussed in more detail below.

The following table sets forth the estimated fair value and the carrying value of each financial instrument:

Financial Instruments Not Recorded at Fair Value

The Company did not elect to measure and record commercial mortgage loans, policy loans, other policyholders funds that are investment-type contracts, short-term debt, or long-term debt at fair value on the consolidated balance sheets.

For disclosure purposes, the fair values of commercial mortgage loans were estimated using an option-adjusted discounted cash flow valuation. The valuation includes both observable market inputs and estimated model parameters.

Significant observable inputs to the valuation include:

• Indicative quarter-end pricing for a package of loans similar to those originated by the Company near quarter-end.
• U.S. Government treasury yields.
• Indicative yields from industrial bond issues.
• The contractual terms of nearly every mortgage subject to valuation.

Significant estimated parameters include:

• A liquidity premium that is estimated from historical loan sales and is applied over and above base yields.
• Adjustments in interest rate spread based on an aggregate portfolio loan-to-value ratio, estimated from historical differential yields with respect to loan-to-value ratios.
• Projected prepayment activity.

For policy loans, the carrying value represents historical cost but approximates fair value. While potentially financial instruments, policy loans are an integral component of the insurance contract and have no maturity date.

The fair value of other policyholder funds that are investment-type contracts was calculated using the income approach in conjunction with the cost of capital method. The parameters used for discounting in the calculation were estimated using the perspective of the principal market for the contracts under consideration. The principal market consists of other insurance carriers with similar contracts on their books.

The fair value for short-term and long-term debt was predominantly based on quoted market prices as of June 30,2012 and December 31, 2011, and trades occurring close to June 30,2012and December 31, 2011.

Financial Instruments Measured and Recorded at Fair Value

Fixed maturity securities, Standard & Poor's (“S&P”) 500 Index call options (“S&P 500 Index options”) and index-based interest guarantees embedded in indexed annuities (“index-based interest guarantees”) are recorded at fair value on a recurring 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, in net investment income for S&P 500 Index options and in interest credited for index-based interest guarantees.

Separate account assets represent segregated funds held for the exclusive benefit of contract holders. The activities of the account primarily relate to participant-directed 401(k) contracts. Separate account assets are recorded at fair value on a recurring basis, with changes in fair value recorded in separate account liabilities. Separate account assets consist of mutual funds. The mutual funds' fair value is determined through Level 1 and Level 2 inputs. The majority of the separate account assets are valued using quoted prices in an active market with the remainder of the assets valued using quoted prices from an independent pricing service. The Company reviews the values obtained from the pricing service for reasonableness through analytical procedures and performance reviews.

Fixed maturity securities are comprised of the following classes:

• U.S. government and agency bonds.
• U.S. state and political subdivision bonds.
• Foreign government bonds.
• Corporate bonds.
• S&P 500 Index options.

  The fixed maturity securities are diversified across industries, issuers and maturities. The Company calculates fair values for all classes of fixed maturity securities using valuation techniques described below. They are placed into three levels depending on the valuation technique used to determine the fair value of the securities.

  The Company uses an independent pricing service to assist management in determining the fair value of these assets. The pricing service incorporates a variety of information observable in the market in its valuation techniques, including:

• Reported trading prices.
• Benchmark yields.
• Broker-dealer quotes.
• Benchmark securities.
• Bids and offers.
• Credit ratings.
• Relative credit information.
• Other reference data.

The pricing service also takes into account perceived market movements and sector news, as well as a bond's terms and conditions, including any features specific to that issue that may influence risk, and thus marketability. Depending on the security, the priority of the use of observable market inputs may change as some observable market inputs may not be relevant or additional inputs may be necessary. The Company generally obtains one value from its primary external pricing service. On a case-by-case basis, the Company may obtain further quotes or prices from additional parties as needed.

The pricing service provides quoted market prices when available. Quoted prices are not always available due to bond market inactivity. The pricing service obtains a broker quote when sufficient information, such as security structure or other market information, is not available to produce a valuation. Valuations and quotes obtained from third party commercial pricing services are non-binding and do not represent quotes on which one may execute the disposition of the assets.

The significant unobservable inputs used in the fair value measurement of the reporting entity's bonds are valuations and quotes received from secondary pricing service, analytical reviews and broker quotes. Significant increases or decreases in any of those inputs in isolation would result in a significantly lower or higher fair value measurement. Generally, a change in the assumption used for the pricing evaluation is accompanied by a directionally similar change in the assumption used for the methodologies.

The Company performs control procedures over the external valuations at least quarterly through a combination of procedures that include an evaluation of methodologies used by the pricing service, analytical reviews and performance analysis of the prices against statistics and trends, back testing of sales activity and maintenance of a securities watch list. As necessary, the Company compares prices received from the pricing service to prices independently estimated by the Company utilizing discounted cash flow models or through performing independent valuations of inputs and assumptions similar to those used by the pricing service in order to ensure prices represent a reasonable estimate of fair value. Although the Company does identify differences from time to time as a result of these validation procedures, the Company did not make any significant adjustments as ofJune 30,2012or December 31, 2011.

S&P 500 Index options and certain fixed maturity securities were valued using Level 3 inputs. The Level 3 fixed maturity securities were valued using matrix pricing, independent broker quotes and other standard market valuation methodologies. The fair value was determined using inputs that were not observable or could not be derived principally from, or corroborated by, observable market data. These inputs included assumptions regarding liquidity, estimated future cash flows and discount rates. Unobservable inputs to these valuations are based on management's judgment or estimation obtained from the best sources available. The Company's valuations maximize the use of observable inputs, which include an analysis of securities in similar sectors with comparable maturity dates and bond ratings. Broker quotes are validated by management for reasonableness in conjunction with information obtained from matrix pricing and other sources.

The Company calculates the fair value for its S&P 500 Index options using the Black-Scholes option pricing model and parameters derived from market sources. The Company's valuations maximize the use of observable inputs, which include direct price quotes from the Chicago Board Options Exchange (“CBOE”) and values for on-the-run treasury securities and London Interbank Offered Rate (“LIBOR”) as reported by Bloomberg. Unobservable inputs are estimated from the best sources available to the Company and include estimates of future gross dividends to be paid on the stocks underlying the S&P 500 Index, estimates of bid-ask spreads, and estimates of implied volatilities on options. Valuation parameters are calibrated to replicate the actual end-of-day market quotes for options trading on the CBOE. The Company performs additional validation procedures such as the daily observation of market activity and conditions and the tracking and analyzing of actual quotes provided by banking counterparties each time the Company purchases options from them. Additionally, in order to help validate the values derived through the procedures noted above, the Company obtains indicators of value from representative investment banks.

The Company uses the income approach valuation technique to determine the fair value of index-based interest guarantees. 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 declarations significantly influence the calculation. Index-based interest guarantees are included in the other policyholder funds line on the Company's consolidated balance sheet.

While valuations for the S&P 500 Index options are sensitive to a number of variables, valuations for S&P 500 Index options purchased are most sensitive to changes in the estimates of bid ask spreads, or the S&P 500 Index value, and the implied volatilities of this index. Significant fluctuations in any of those inputs in isolation would result in a significantly lower or higher fair value measurement. Generally, an increase or decrease used in the assumption for the implied volatilities and in the S&P 500 Index value would result in a directionally similar change in the fair value of the asset.

Valuations for the index-based interest guarantees are sensitive to a number of variables, but are most sensitive to the S&P 500 Index value, the implied volatilities of this index, and LIBOR as reported by Bloomberg. Generally, a significant increase or decrease used in the assumption for the implied volatilities and in the S&P 500 Index value would result in a directionally similar change, while an increase or decrease in LIBOR would result in a directionally opposite change in the fair value of the liability.

Valuations for commercial mortgage loans and real estate owned measured on a nonrecurring basis are sensitive to a number of variables, but are most sensitive to the capitalization rate. Generally, an increase or decrease used in the assumption for the capitalization rate would result in a directionally similar change in the fair value of the asset.

Quantitative information regarding significant unobservable inputs used in Level 3 valuation of assets and liabilities measured and recorded at fair value is as follows:

• Represents various assumptions derived from market data, which include estimates of bid ask spreads and the implied volatilities for the S&P 500 index.
• Represents various actuarial assumptions which include combined lapse, mortality and withdrawal decrement rates which generally have a range of inputs from 5%-36%.
• Capitalization rates are used as an internal analysis in converting the underlying property's income to an estimated property value.

For all periods disclosed above, fixed maturity securities transferred into Level 3 from Level 2 are the result of the Company being unable to obtain observable assumptions in the market. Fixed maturity securities transferred out of Level 3 into Level 2 are the result of the Company being able to obtain observable assumptions in the market. There were no transfers between Level 1 and Level 2 for the second quarter of2012 and 2011.

The following table sets forth the changes in unrealized gains (losses) included in net income relating to positions that the Company continued to hold:

		Three Months Ended				Six Months Ended
		June 30,				June 30,

Liabilities:
	Index-based interest guarantees	$	(1.9)	$	(1.2)	$	(8.4)	$	(4.5)

Changes to the fair value of fixed maturity securities, excluding S&P 500 Index options, were recorded in other comprehensive income. Changes to the fair value of the S&P 500 Index options were recorded to net investment income. Changes to the fair value of the index-based interest guarantees were recorded as interest credited. The interest credited amount included negative interest on policyholder funds due to changes in the Level 3 actuarial assumptions of $1.1 million and $1.5 million for the second quarters and first six months of 2012 and 2011, respectively.

Certain assets and liabilities are measured at fair value on a nonrecurring basis such as impaired commercial mortgage loans with specific allowances for losses and real estate acquired in satisfaction of debt through foreclosure or the acceptance of deeds in lieu of foreclosure on commercial mortgage loans (“real estate owned”). The impaired commercial mortgage loans and real estate owned are valued using Level 3 measurements. These Level 3 inputs are reviewed for reasonableness by management and evaluated on a quarterly basis. The commercial mortgage loan measurements include valuation of the market value of the asset using general underwriting procedures and appraisals. Real estate owned is initially recorded at estimated net realizable value, which includes an estimate for disposal costs. These amounts may be adjusted in a subsequent period as independent appraisals are received.

The following table sets forth the assets measured at fair value on a nonrecurring basis as of June 30,2012 that the Company continued to hold:

		June 30, 2012
		Total		Level 1		Level 2		Level 3

Derivative Financial Instruments [Abstract]

Derivative Financial Instruments

8.       DERIVATIVE FINANCIAL INSTRUMENTS

The Company sells indexed annuities, which permit the holder to elect a fixed 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 and minimum guarantees. 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. The Company estimates the fair value of the index-based interest 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. The liability represents an estimate of the cost of the options to be purchased in the future to manage the risk related to the index-based interest guarantees. The liability for index-based interest guarantees is the present value of future cash flows attributable to the projected index growth that is in excess of cash flows attributable to fixed interest rates guarantees. The excess cash flows are discounted back to the date of the balance sheet using current market indicators for future interest rates and option costs. Cash flows depend on actuarial estimates for policyholder lapse behavior and management's discretion in setting renewal index-based interest guarantees.

The Company purchases S&P 500 Index options for its interest crediting strategy used in its indexed annuity product. The S&P 500 Index options are purchased from investment banks and are selected in a manner that supports the amount of interest that is expected to be credited in the current year to annuity policyholder accounts that are dependent on the performance of the S&P 500 Index. The purchase of S&P 500 Index options is a pivotal part of the Company's risk management strategy for indexed annuity products. The S&P 500 Index options are exclusively used for risk management. While valuations of the S&P 500 Index options are sensitive to a number of variables, valuations for S&P 500 Index options purchased are most sensitive to changes in the S&P 500 Index value and the implied volatilities of this index. The Company generally purchases one S&P 500 Index option contract per month, which has an expiry date of one year from the date of purchase.

The notional amount of the Company's S&P 500 index options at June 30,2012and December 31, 2011 was $307.8million and $303.1million, respectively. Option premiums paid for the Company's index option contracts were $2.8 million and $2.4million for the second quarters of2012and 2011, respectively, and were $4.8 million and $4.7 million for the first six months of2012 and 2011, respectively. The Company received $2.4 million and $4.6million for options exercised for the second quarters of2012 and 2011, respectively, and$4.0 million and $9.0millionfor the first six months of2012 and 2011, respectively.

The Company recognizes all derivative investments as assets or liabilities on the balance sheet at fair value. The Company does not designate its derivatives as hedging instruments and thus does not use hedge accounting. As such, any change in the fair value of the derivative assets and derivative liabilities is recognized as income or loss in the period of change. See “Note 6—Fair Value” for additional information regarding the fair value of the Company's derivative assets and liabilities.

The following table sets forth the fair value of the Company's derivative assets and liabilities:

			June 30,		December 31,

The following table sets forth the amount of gain or loss recognized in earnings from the change in fair value of the Company's derivative assets and liabilities:

			Three Months Ended				Six Months Ended

		Net (loss) gain	$	(0.6)	$	0.7	$	(0.3)	$	1.7

Changes in the fair value of the S&P 500 Index options and index-based interest guarantees are primarily the result of fluctuations in the S&P 500 Index and are recorded to net investment income and interest credited, respectively.Interest credited for the second quarter of 2012 was impacted bythe Company's annual update of the key assumptions used to value index-based interest guarantees, a process known as “unlocking.”The interest credited amount included negative interest related to the 'unlocking' process of $1.1 million and $1.5 million for the second quarters of2012 and 2011, respectively, and $1.1 million and $1.5 million for first six months of2012 and 2011, respectively.

The Company does not bear derivative-related risk that would require it to post collateral with another institution, and its index option contracts do not contain counterparty credit-risk-related contingent features. The Company is exposed to the credit worthiness of the institutions from which it purchases its S&P 500 Index options and these institutions' continued abilities to perform according to the terms of the contracts. The current values for the credit exposure have been affected by fluctuations in the S&P 500 Index. The Company's maximum credit exposure would require an increase of approximately 8.9% in the value of the S&P 500 Index. The maximum credit risk is calculated using the cap strike price of the Company's S&P 500 Index options less the floor price, multiplied by the notional amount of the S&P 500 Index options.

Net Income Per Common Share

Net Income Per Common Share [Abstract]

Net Income Per Common Share

2.       NET INCOME PER COMMON SHARE

Net income per basic 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 stock award 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.

The following table sets forth the calculation of net income per basic and diluted weighted-average common shares outstanding:

12.INCOME TAXES

Income taxes may differ from the amount computed by applying the Federal corporate tax rate of 35% to pre-tax income because of the net results of permanent differences between book and taxable income and because of the inclusion of state and local income taxes, net of the federal tax benefit.

The following table sets forth the combined federal and state effective income tax rates:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2012		2011		2012		2011
Combined federal and state effective income tax rates	11.5	%	27.6	%	21.5	%	30.9	%

During the first six months of2012, and throughout 2011, the Company purchased tax-advantaged investments, contributing to a decrease in the effective tax rate. In addition the effective tax rate was also reduced by favorable book-to-tax differences relative to a lower level of income in 2012. These investments, along with lower pre-tax net income,were the primary driversof thedecreases inthe effective tax ratefor the second quarter and first six months of2012 when compared to the same periods for 2011.
