Nature of Operations and Significant Accounting Policies	1. Nature of Operations and Significant Accounting Policies Basis of Presentation The accompanying unaudited consolidated financial statements of Principal Financial Group,Inc. (PFG), its majority-owned subsidiaries and its consolidated variable interest entities (VIEs), have been prepared in conformity with accounting principles generally accepted in the U.S. (U.S. GAAP) for interim financial statements and with the instructions to Form10-Q and Article10 of Regulation S-X. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June30, 2009, are not necessarily indicative of the results that may be expected for the year ended December31, 2009. These interim unaudited consolidated financial statements should be read in conjunction with our annual audited financial statements as of December31, 2008, included in our Form10-K for the year ended December31, 2008, filed with the United States Securities and Exchange Commission (SEC). The accompanying consolidated statement of financial position as of December31, 2008, has been derived from the audited consolidated statement of financial position but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. We have evaluated subsequent events through August5, 2009, which was the date our consolidated financial statements were issued. Reclassifications have been made to prior period financial statements to conform to the June30, 2009, presentation. See Recent Accounting Pronouncements for impact of new accounting guidance on prior period financial statements. Recent Accounting Pronouncements On June30, 2009, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No.168, The FASB Accounting Standards CodificationTMand the Hierarchy of Generally Accepted Accounting Principles, a replacement of FASB Statement No.162 (SFAS 168). This statement replaces SFAS No.162, The Hierarchy of Generally Accepted Accounting Principles, and establishes the FASB Accounting Standards CodificationTM(Codification) as the source of authoritative accounting principles recognized by the FASB to be applied by nongovernmental entities in the preparation of financial statements in conformity with U.S. GAAP. Rulesand interpretive releases of the SEC under federal securities laws are also sources of authoritative U.S. GAAP for SEC registrants. All guidance contained in the Codification carries an equal level of authority. SFAS 168 is effective for financial statements issued for interim and annual periods ending after September15, 2009. We do not anticipate that SFAS 168 will have a material impact on our consolidated financial statements. On June12, 2009, the FASB issued SFAS No.166, Accounting for Transfers of Financial Assets, an amendment of FASB Statement No.140 (SFAS 166). The objective of SFAS 166 is to improve the relevance, representational faithfulness, and comparability of the information that a reporting entity provides in its financial repor

Investments	2. Investments Fixed Maturities and Equity Securities Fixed maturity securities include bonds, mortgage-backed securities, redeemable preferred stock and certain nonredeemable preferred stock. Equity securities include mutual funds, common stock and nonredeemable preferred stock. We classify fixed maturity securities and equity securities as either available-for-sale or trading at the time of the purchase and, accordingly, carry them at fair value. See Note9, Fair Value of Financial Instruments, for methodologies related to the determination of fair value. Unrealized gains and losses related to available-for-sale securities, excluding those in fair value hedging relationships, are reflected in stockholders equity, net of adjustments related to deferred policy acquisition costs (DPAC), sales inducements, unearned revenue reserves, derivatives in cash flow hedge relationships and applicable income taxes. Unrealized gains and losses related to trading securities and hedged portions of available-for-sale securities in fair value hedging relationships are reflected in net income as net realized capital gains (losses). The cost of fixed maturity securities is adjusted for amortization of premiums and accrual of discounts, both computed using the interest method. The cost of fixed maturity securities and equity securities is adjusted for other-than-temporary impairments recognized in net income. For loan-backed and structured securities, we recognize income using a constant effective yield based on currently anticipated prepayments using a tool that models the prepayment behavior of the underlying collateral based on the current interest rate environment. The amortized cost, gross unrealized gains and losses, other-than-temporary impairments in OCI and fair value of fixed maturities and equity securities available-for-sale as of June30, 2009, are summarized as follows: Amortized cost Gross unrealized gains Gross unrealized losses Other-than-temporary impairments in OCI Fair value (in millions) Fixed maturities, available-for-sale: U.S. government and agencies $ 570.2 $ 4.8 $ 0.8 $ $ 574.2 Non-U.S. governments 708.1 82.7 5.8 785.0 States and political subdivisions 1,968.4 33.9 40.4 1,961.9 Corporate 33,176.7 679.0 2,890.9 28.0 30,936.8 Residential mortgage-backed securities 2,187.7 64.3 1.7 2,250.3 Commercial mortgage-backed securities 5,355.3 8.6 1,825.8 31.7 3,506.4 Collateralized debt obligations 641.7 3.0 316.0 34.1 294.6 Other debt obligations 2,436.3 19.2 425.3 40.8 1,989.4 Total fixed maturities, available-for-sale $ 47,044.4 $ 895.5 $ 5,506.7 $ 134.6 $ 42,298.6 Total equity securities, available-for-sale $ 294.2 $ 12.0 $ 93.7 $ $ 212.5 The amortized cost and fair value of fixed maturities available-for-sale as of June30, 2009, by contractual maturity, were as follows: Amortized cost Fair value (in millions) Due in one year or less

Derivative Financial Instrument

Derivative Financial Instruments

Notes to Consolidated Financial Statements
Derivative Financial Instruments	3. Derivative Financial Instruments Derivatives are generally used to hedge or reduce exposure to market risks associated with assets held or expected to be purchased or sold and liabilities incurred or expected to be incurred. Derivatives are used to change the characteristics of our asset/liability mix consistent with our risk management activities. Derivatives are also used in asset replication strategies. We do not buy, sell or hold these investments for trading purposes. Types of Derivative Instruments Interest Rate Contracts Interest rate risk is the risk that we will incur economic losses due to adverse changes in interest rates. Sources of interest rate risk include the difference between the maturity and interest rate changes of assets with the liabilities they support, timing differences between the pricing of liabilities and the purchase or procurement of assets and changing cash flow profiles from original projections due to prepayment options embedded within asset and liability contracts. We use various derivatives to manage our exposure to fluctuations in interest rates. Interest rate swaps are contracts in which we agree with other parties to exchange, at specified intervals, the difference between fixed rate and floating rate interest amounts based upon designated market rates or rate indices and an agreed upon notional principal amount. Generally, no cash is exchanged at the outset of the contract and no principal payments are made by either party. Cash is paid or received based on the terms of the swap. These transactions are entered into pursuant to master agreements that provide for a single net payment to be made by one counterparty at each due date. We use interest rate swaps primarily to more closely match the interest rate characteristics of assets and liabilities arising from timing mismatches between assets and liabilities (including duration mismatches). We also use interest rate swaps to hedge against changes in the value of assets we anticipate acquiring and other anticipated transactions and commitments. Interest rate swaps are used to hedge against changes in the value of the guaranteed minimum withdrawal benefit (GMWB) liability. The GMWB rider on our variable annuity products provides for guaranteed minimum withdrawal benefits regardless of the actual performance of various equity and/or fixed income funds available with the product. A swaption is an option to enter into an interest rate swap at a future date. We have written these options and received a premium in order to transform our callable liabilities into fixed term liabilities. Swaptions provide us the benefit of the agreed-upon strike rate if the market rates for liabilities are higher, with the flexibility to enter into the current market rate swap if the market rates for liabilities are lower. Swaptions not only hedge against the downside risk, but also allow us to take advantage of any upside benefits. In exchange-traded futures transactions, we agree to purchase or sell a specified number of contracts, the values of which are determined by the values of designated classes of securities, and to post variation margin on a

On May18, 2009, we issued $750.0 million of senior notes. We issued a $400.0 million series of notes that bear interest at 7.875% and will mature on May15, 2014, and a $350.0 million series of notes that bear interest at 8.875% and will mature on May15, 2019. Interest on the notes is payable semi-annually on May15 and November15 each year, beginning on November15, 2009. The proceeds will primarily be used to refinance $440.9 million of notes due on August15, 2009, with the remaining proceeds being used for general corporate purposes.

Federal Income Taxes

Notes to Consolidated Financial Statements
Federal Income Taxes	5. Federal Income Taxes The effective income tax rate for the three and six months ended June30, 2009, was lower than the U.S. corporate income tax rate of 35% (U.S. statutory rate) primarily due to income tax deductions allowed for corporate dividends received and the interest exclusion from taxable income. Taxes on our share of earnings generated from equity method investments reflected in net investment income also contributed to a lower than U.S. statutory rate. The effective income tax rates for the three and six months ended June30, 2008, were lower than the U.S. statutory rate primarily due to income tax deductions allowed for corporate dividends received and additional U.S. foreign tax credits resulting from the enactment of legislation to increase the Brazilian tax rate in the second quarter of 2008.As we apply the equity method of accounting to our Brazilian operations, the net increase in deferred tax liabilities associated with the newly enacted rate is reflected in net investment income. The effective income tax rate for the six months ended June30, 2008, was also lower than the prevailing U.S. statutory rate due to the release of state deferred income tax liabilities associated with a reorganization of certain subsidiaries. The Internal Revenue Service (IRS) is currently auditing our federal income tax returns for the years 2004 through 2007. The IRS informed us of their intent to audit our 2008 tax return beginning in early 2010. We do not expect the results of these audits or developments in other tax areas to significantly change the possible increase in the amount of unrecognized tax benefits, but the outcome of tax reviews is uncertain and unforeseen results can occur. Consistent with December31, 2008, we estimate that it is reasonably possible that the amount of our unrecognized tax benefits could increase $0.0 to $11.0 million within the next twelve months.

Contributions Our funding policy for our qualified pension plan is to fund the plan annually in an amount at least equal to the minimum annual contribution required under the Employee Retirement Income Security Act (ERISA) and, generally, not greater than the maximum amount that can be deducted for federal income tax purposes. The minimum annual contribution for 2009 will be zero so we will not be required to fund our qualified pension plan during 2009. However, it is possible that we may fund the qualified and nonqualified pension plans in 2009 for a combined total of between $20.0 million to $100.0 million. During both the three and six months ended June30, 2009, we contributed $12.5 million to these plans.

Contingencies, Guarantees and Indemnifications	7. Contingencies, Guarantees and Indemnifications Litigation and Regulatory Contingencies We are regularly involved in litigation, both as a defendant and as a plaintiff, but primarily as a defendant. Litigation naming us as a defendant ordinarily arises out of our business operations as a provider of asset management and accumulation products and services, life, health and disability insurance. Some of the lawsuits are class actions, or purport to be, and some include claims for punitive damages. In addition, regulatory bodies, such as state insurance departments, the SEC, the Financial Industry Regulatory Authority, the Department of Labor and other regulatory bodies regularly make inquiries and conduct examinations or investigations concerning our compliance with, among other things, insurance laws, securities laws, ERISA and laws governing the activities of broker-dealers. We receive requests from regulators and other governmental authorities relating to other industry issues and may receive additional requests, including subpoenas and interrogatories, in the future. On November8, 2006, a trustee of Fairmount ParkInc. Retirement Savings Plan filed a putative class action lawsuit in the United States District Court for the Southern District of Illinois against Principal Life. Principal Lifes Motion to Transfer Venue was granted and the case is now pending in the Southern District of Iowa. The complaint alleged, among other things, that Principal Life breached its alleged fiduciary duties while performing services to 401(k)plans by failing to disclose, or adequately disclose, to employers or plan participants the fact that Principal Life receives revenue sharing fees from mutual funds that are included in its pre-packaged 401(k)plans and allegedly failed to use the revenue to defray the expenses of the services provided to the plans. Plaintiff further alleged that these acts constitute prohibited transactions under ERISA. Plaintiff sought to certify a class of all retirement plans to which Principal Life was a service provider and for which Principal Life received and retained revenue sharing fees from mutual funds. On August27, 2008, the Plaintiffs Motion for ClassCertification was denied. The Plaintiff filed a petition seeking permission to appeal that ruling. The petition was denied on October28, 2008. On May11, 2009, Plaintiff filed a new Motion for ClassCertification. Principal Life is aggressively defending the lawsuit. On August28, 2007, two plaintiffs, Walsh and Young, filed a putative class action lawsuit in the United States District Court for the Southern District of Iowa against Principal Life and Princor Financial Services Corporation (the Principal Defendants). The lawsuit alleges that the Principal Defendants breached alleged fiduciary duties to participants in employer-sponsored 401(k)plans who were retiring or leaving their respective plans, including providing misleading information and failing to act solely in the interests of the participants, resulting in alleged violations of ERISA. The Principal Defendants are aggressively defending the lawsuit. On February28, 2007, Luz Zapien (Zapien) filed a secu

Fair Value of Financial Instruments	9. Fair Value of Financial Instruments We use fair value measurements to record fair value of certain assets and liabilities and to estimate fair value of financial instruments not recorded at fair value but required to be disclosed at fair value under SFAS 107. We follow SFAS 157 to determine SFAS 107 fair value disclosure amounts. Certain financial instruments, particularly policyholder liabilities other than investment-type insurance contracts, are excluded from these fair value disclosure requirements. Valuation hierarchy SFAS157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). For SFAS 157 disclosures, SFAS 157 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels. Level 1 Fair values are based on unadjusted quoted prices in active markets for identical assets or liabilities. Our Level 1 assets and liabilities primarily include exchange traded equity securities, mutual funds and U.S. Treasury bonds. Level 2 Fair values are based on inputs other than quoted prices within Level 1 that are observable for the asset or liability, either directly or indirectly. Our Level 2 assets and liabilities primarily include fixed maturity securities (including public and private bonds), equity securities, over-the-counter derivatives and other investments for which public quotations are not available but that are priced by third-party pricing services or internal models using substantially all observable inputs. Level 3 Fair values are based on significant unobservable inputs for the asset or liability. Our Level 3 assets and liabilities include certain fixed maturity securities, private equity securities, complex derivatives and embedded derivatives that must be priced using broker quotes or other valuation methods that utilize at least one significant unobservable input. Determination of fair value The following discussion describes the valuation methodologies used for assets and liabilities measured or disclosed at fair value. The techniques utilized in estimating the fair values of financial instruments are reliant on the assumptions used. Care should be exercised in deriving conclusions about our business, its value or financial position based on the fair value information of financial instruments presented below. Fair value estimates are made at a specific point in time, based on available market information and judgments about the financial instrument. Such estimates do not consider the tax impact of the realization of unrealized gains or losses. In addition, the disclosed fair value may not be realized in the immediate settlement of the financial instrument. We validate prices through an investment analyst review process, which includes validation through direct interaction with external sources, review of recent trade activity or use of internal models. In circumstances where broker quotes are used to value an instrument, we generally receive one non-binding quote. Broker quotes are val

Segment Information	10. Segment Information We provide financial products and services through the following segments: U.S. Asset Accumulation, Global Asset Management, International Asset Management and Accumulation and Life and Health Insurance. In addition, there is a Corporate segment. The segments are managed and reported separately because they provide different products and services, have different strategies or have different markets and distribution channels. The U.S. Asset Accumulation segment provides retirement and related financial products and services primarily to businesses, their employees and other individuals. The Global Asset Management segment provides asset management services to our asset accumulation business, our life and health insurance operations, the Corporate segment and third-party clients. The International Asset Management and Accumulation segment consists of Principal International, which has operations in Brazil, Chile, China, Hong Kong Special Administrative Region, India, Indonesia, Malaysia, Mexico and Singapore. We focus on countries with large middle classes, favorable demographics and growing long-term savings with defined contribution markets. We entered these countries through acquisitions, start-up operations and joint ventures. The Life and Health insurance segment provides individual life insurance, group health insurance and specialty benefits, which consists of group dental and vision insurance, individual and group disability insurance and group life insurance, throughout the United States. The Corporate segment manages the assets representing capital that has not been allocated to any other segment. Financial results of the Corporate segment primarily reflect our financing activities (including interest expense), income on capital not allocated to other segments, inter-segment eliminations, income tax risks and certain income, expenses and other after-tax adjustments not allocated to the segments based on the nature of such items. Management uses segment operating earnings in goal setting, as a basis for determining employee compensation and in evaluating performance on a basis comparable to that used by securities analysts. We determine segment operating earnings by adjusting U.S. GAAP net income for net realized capital gains (losses), as adjusted, and other after-tax adjustments which management believes are not indicative of overall operating trends. Net realized capital gains (losses), as adjusted, are net of income taxes, related changes in the amortization pattern of DPAC and sales inducements, recognition of deferred front-end fee revenues for sales charges on retirement products and services, net realized capital gains and losses distributed, noncontrolling interest capital gains and losses and certain market value adjustments to fee revenues. Net realized capital gains (losses), as adjusted, exclude periodic settlements and accruals on non-hedge derivative instruments and exclude certain market value adjustments of embedded derivatives. Segment operating revenues exclude net realized capital gains (losses) (except periodic settlements and accruals on non-hedge derivatives), inc

Stock-Based Compensation Plans	11. Stock-Based Compensation Plans As of June30, 2009, we have the 2005 Stock Incentive Plan, the Employee Stock Purchase Plan, the 2005 Directors Stock Plan, the Stock Incentive Plan, the Directors Stock Plan and the Long-Term Performance Plan (Stock-Based Compensation Plans). As of May17, 2005, no new grants will be made under the Stock Incentive Plan, the Directors Stock Plan or the Long-Term Performance Plan. As of June30, 2009, the maximum number of new shares of common stock that were available for grant under the 2005 Stock Incentive Plan and the 2005 Directors Stock Plan was 13.4 million. The compensation cost that was charged against income for stock-based awards granted under the Stock-Based Compensation Plans is as follows: For the six months ended June30, 2009 2008 (in millions) Compensation cost $ 26.2 $ 27.4 Related income tax benefit 8.6 9.0 Capitalized as part of an asset 2.0 2.6 Nonqualified Stock Options Nonqualified stock options were granted to certain employees under the 2005 Stock Incentive Plan. Total options granted were 2.2 million for the six months ended June30, 2009. The fair value of these options was determined using the Black-Scholes option valuation model assuming a weighted-average dividend yield of 4.1 percent, a weighted-average expected volatility of 55.0 percent, a weighted-average risk-free interest rate of 2.1 percent and a weighted-average expected term of 6 years. The weighted-average estimated fair value of stock options granted during the six months ended June30, 2009, was $4.07 per share. As of June30, 2009, there were $11.6 million of total unrecognized compensation costs related to nonvested stock options. The costs are expected to be recognized over a weighted-average service period of approximately 1.7 years. Performance Share Awards Performance share awards were granted to certain employees under the 2005 Stock Incentive Plan. Total performance share awards granted were 0.5 million for the six months ended June30, 2009. The performance share awards granted represent initial target awards and do not reflect potential decreases resulting from the final performance objective to be determined at the end of the performance period. The actual number of shares to be awarded at the end of each performance period will be either 0% or 100% of the initial target awards. The fair value of performance share awards is determined based on the closing stock price of our common shares on the grant date. The weighted-average grant date fair value of these performance share awards granted was $11.07 per common share. As of June30, 2009, there were $3.6 million of total unrecognized compensation costs related to nonvested performance share awards granted. The costs are expected to be recognized over a weighted-average service period of approximately 1.9 years. Restricted Stock Units Restricted stock units were issued to certain employees and agents pursuant to the 2005 Stock Incentive Plan. Total restricted stock units granted were 1.8 million for the six months ended June30, 2009. The fair value of restricted s

Condensed Consolidating Financial Information	13. Condensed Consolidating Financial Information Principal Life has established special purpose entities to issue secured medium-term notes. Under the program, the payment obligations of principal and interest on the notes are secured by funding agreements issued by Principal Life. Principal Lifes payment obligations on the funding agreements are fully and unconditionally guaranteed by PFG. All of the outstanding stock of Principal Life is indirectly owned by PFG and PFG is the only guarantor of the payment obligations of the funding agreements. The following tables set forth condensed consolidating financial information of (i)PFG, (ii)Principal Life, (iii)Principal Financial Services,Inc. (PFS) and all other direct and indirect subsidiaries of PFG on a combined basis and (iv)the eliminations necessary to arrive at the information for PFG on a consolidated basis as of June30, 2009 and December31, 2008, and for the six months ended June30, 2009 and 2008. In presenting the condensed consolidating financial statements, the equity method of accounting has been applied to (i)PFGs interest in PFS, (ii)Principal Lifes interest in all direct subsidiaries of Principal Life and (iii)PFSs interest in Principal Life even though all such subsidiaries meet the requirements to be consolidated under U.S. GAAP. Earnings of subsidiaries are, therefore, reflected in the parents investment and earnings. All intercompany balances and transactions, including elimination of the parents investment in subsidiaries, between PFG, Principal Life and PFS and all other subsidiaries have been eliminated, as shown in the column Eliminations and Other.
