GENERAL INFORMATION AND HISTORY

Principal Life Insurance Company (the “Company”) is the issuer of the Principal® Lifetime Income Solutions II Variable Annuity (the “Contract”) and serves as custodian of its assets. The Company is a stock life insurance company with authority to transact life and annuity business in all states of the United States and the District of Columbia. The Company’s home office is located at: Principal Financial Group, Des Moines, Iowa 50392. The Company is a wholly owned subsidiary of Principal Financial Services, Inc., which in turn, is a wholly owned direct subsidiary of Principal Financial Group, Inc., a publicly-traded company.

On June 24, 1879, the Company was incorporated under Iowa law as a mutual assessment life insurance company named Bankers Life Association. The Company became a legal reserve life insurance company and changed its name to Bankers Life Company in 1911. In 1986, the Company changed its name to Principal Mutual Life Insurance Company. In 1998, the Company became Principal Life Insurance Company, a subsidiary stock life insurance company of Principal Mutual Holding Company, as part of a reorganization into a mutual insurance holding company structure. In 2001, Principal Mutual Holding Company converted to a stock company through a process called demutualization, resulting in the current organizational structure.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Ernst & Young LLP, 801 Grand Avenue, Suite 3100, Des Moines, Iowa 50309, serves as the independent registered public accounting firm for Principal Life Insurance Company Separate Account B and the Principal Life Insurance Company.

PRINCIPAL UNDERWRITER

The principal underwriter of the Contract is Principal Securities, Inc. ("PSI") which is a wholly owned subsidiary of Principal Financial Services, Inc. and an affiliate of the Company. The address of PSI is the Principal Financial Group, 655 9th Street, Des Moines, Iowa 50392. PSI was incorporated in Iowa in 1968 and is a securities broker-dealer registered with the Securities Exchange Commission as well as a member of the FINRA. The Contracts may also be sold through other broker-dealers authorized by PSI and applicable law to do so. Registered representatives of such broker-dealers may be paid on a different basis than described below.

The Contract’s offering to the public is continuous. As the principal underwriter, PSI is paid for the distribution of the Contract. For the last fiscal year PSI has received and retained the following commissions:

2021 received/retained	2020 received/retained	2019 received/retained
$14,004,267/$0	$12,188,895/$0	$17,397,375/$0

CALCULATION OF PERFORMANCE DATA

The Separate Account may publish advertisements containing information (including graphs, charts, tables and examples) about the performance of one or more of its divisions. Separate performance figures will be shown for the Contract without the premium payment credit rider and for the Contract with the premium payment credit rider.

The Contract was not offered prior to December 28, 2016. However, the certain divisions invest in underlying mutual funds which were offered prior to the date the Contract was available. Thus, the Separate Account may publish advertisements containing information about the hypothetical performance of one or more of its divisions for this Contract as the Contract was issued on or after the date the underlying mutual fund was first offered. The hypothetical performance from the date of inception of the underlying mutual fund in which the division invests is derived by reducing the actual performance of the underlying mutual fund by the highest level of fees and charges of the Contract as if it had been in existence.

In addition, as certain of the underlying mutual funds have added classes since the inception of the fund, performance may be shown for periods prior to the inception date of the new class which represents the historical results of initial class shares adjusted to reflect the fees and expenses of the new class.

The yield and total return figures described below will vary depending upon market conditions, the composition of the underlying mutual fund’s portfolios and operating expenses. These factors and possible differences in the methods used in calculating yield and total return should be considered when comparing the Separate Account performance figures to performance figures published for other investment vehicles.

3

The Separate Account may also quote rankings, yields or returns as published by independent statistical services or publishers and information regarding performance of certain market indices. Any performance data quoted for the Separate Account represents only historical performance and is not intended to indicate future performance.

From time to time the Separate Account advertises its Fidelity VIP Government Money Market Division’s “yield” and “effective yield” for the Contract. Both yield figures are based on historical earnings and are not intended to indicate future performance. The “yield” of the division refers to the income generated by an investment under the Contract in the division over a 7-day period (which period will be stated in the advertisement). This income is then “annualized.” That is, the amount of income generated by the investment during that week is assumed to be generated each week over a 52-week period and is shown as a percentage of the investment. The “effective yield” is calculated similarly but, when annualized, the income earned by an investment in the division is assumed to be reinvested. The “effective yield” will be slightly higher than the “yield” because of the compounding effect of this assumed reinvestment. Neither yield quotation reflects a sales load deducted from purchase payments which, if included, would reduce the “yield” and “effective yield.”

	Yield For the Period Ended December 31, 2021
For Contracts:	7-Day Annualized Yield	7-Day Effective Yield
without a surrender charge	-1.41%	-1.40%
with a surrender charge	-7.41%	-7.40%

Also, from time to time, the Separate Account will advertise the average annual total return of its various divisions. The average annual total return for any of the divisions is computed by calculating the average annual compounded rate of return over the stated period that would equate an initial $1,000 investment to the ending redeemable Contract value. The Separate Account may also advertise total return figures for its divisions for a specified period that does not take into account the surrender charge in order to illustrate the change in the division’s unit value over time. See “Charges” in the Prospectus for a discussion of surrender charges.

Following are the hypothetical average annual total returns for the period ending December 31, 2021 assuming the Contract had been offered as of the effective dates of the underlying mutual funds in which the divisions invest (the performance calculations with Surrender Charge are in accordance with the SEC standard, while the performance calculations without the Surrender Charge are not in accordance with the SEC standard):

TAXATION UNDER CERTAIN RETIREMENT PLANS

INDIVIDUAL RETIREMENT ANNUITIES

Contributions. Individuals may make contributions for individual retirement annuity (IRA) contracts. Individuals may make deductible contributions (for any year) up to the lesser of the amount shown in the chart or 100% of compensation.

Such individuals may establish a traditional IRA for a non-working spouse (if they file a joint return). The annual contribution for both spouses’ contracts cannot exceed the lesser of the amount shown in the chart or 100% of the working spouse’s compensation. No more than the individual IRA limit may be contributed to either spouse’s IRA for any year.

Traditional IRA - Maximum Annual Contribution
Year	Individual IRA	Individual IRA + Spousal IRA
2021	$6,000	$12,000
2022	$6,000	$12,000

For succeeding years, limits are indexed for cost of living.

Individuals age 50 or over are also permitted to make additional “catch-up” contributions. The additional contribution is $1,000 in 2021 and 2022. These additional catch-up contributions can be applied for Spousal IRA purposes.

Contributions may be tax deductible. If an individual and his/her spouse do not participate in a qualified retirement plan, the contributions to an IRA are fully tax deductible regardless of income. If an individual is an active participant in a qualified retirement plan, his/her ability to deduct the contributions depends upon his/her income level and tax filing status.

For individuals who are not active plan participants but whose spouses are, deductibility of traditional IRA contributions is phased out if the couple files a joint return and the Modified Adjusted Gross Income is between $204,000 and $214,000 in 2022.

Deductibility of Traditional IRA Contributions for Active Plan Participants
Married Individuals (Filing Jointly)			Single/Head of Household Individual
Year	Limited Deduction	No Deduction	Year	Limited Deduction	No Deduction
2021	$105,000	$125,000	2021	$66,000	$76,000
2022	$109,000	$129,000	2022	$68,000	$78,000

An individual may make non-deductible IRA contributions to the extent of the excess of:

    (1)    The lesser of maximum annual contribution or 100% of compensation, over

    (2)    The IRA deductible contributions made with respect to the individual.

A person whose filing status is "married, filing separately" may not make a full traditional IRA deduction contribution, unless the couple is separated and have been living apart for the entire year. Only a partial deductible contribution is allowed if your Modified Adjusted Gross Income is less than $10,000.

Taxation of Distributions. Distributions from IRA Contracts are taxed as ordinary income to the recipient, although special rules exist for the tax-free return of non-deductible contributions. In addition, taxable distributions received under an IRA Contract prior to age 59 ½ are subject to a 10% penalty tax in addition to regular income tax. Exempted from this 10% tax penalty are the following types of distributions: distributions due to death; distributions due to disability; if the distribution is paid as part of a series of substantially equal periodic payments made for the life (or life expectancy) of the Owner or the joint lives (or joint life expectancies) of the Owner and the Owner's designated Beneficiary; distributions to pay deductible medical expenses; distributions for unemployed health insurance premiums; distributions for first-time home purchases (up to $10,000); distributions for higher education expenses; made on account of certain levies on income and payments; qualified reservist distributions; and distributions for certain natural disaster victims; qualified birth or adoption distributions (up to $5,000).

5

Required Distributions. Generally, distributions from IRA Contracts must commence not later than April 1 of the calendar year following the calendar year in which the owner attains age 72 (“Required Beginning Date”), and such distributions must be made over a period that does not exceed the uniform lifetime distribution period or in certain instances under the joint life and last survivor period established by the IRS.

Upon the death of the Owner the required minimum distribution options available to the beneficiary will depend upon their status at the time of death. An eligible designated beneficiary must direct that payment of his/her benefits be made or started no later than December 31 of the year following the year of Owner’s death with annual distributions of at least the required minimum distribution. An eligible designated beneficiary is any designated beneficiary who is (1) the Owner’s spouse, (2) no more than ten (10) years younger than the Owner, (3) the Owner’s minor child who has not reached majority, (4) disabled, or chronically ill. If the surviving spouse is the eligible designated beneficiary on the IRA Contract, the surviving spouse may have additional distribution options.

A non-eligible individual designated beneficiary must distribute the entire balance of the IRA Contract by December 31 of the year in which occurs the tenth anniversary of the Owner’s death. An eligible designated beneficiary who is the Owner’s minor child ceases to retain the status upon reaching majority. Upon reaching majority the entire remaining balance of the Contract must be distributed by December 31 of the year in which occurs the tenth anniversary of the minor attaining majority.

If, Owner had not reached his or her Required Beginning Date and there is no designated beneficiary or Owner’s beneficiary is not an individual, the entire balance of the IRA Contract must be paid by December 31 of the year in which occurs the fifth anniversary of Owner’s death.If Owner had attained his or her Required Beginning Date prior to death, distributions must continue at least as rapidly as under the method in effect at the date of death. A penalty tax of 50% will be imposed on the amount by which the required minimum distribution in any year exceeds the amount actually distributed in that year.

Tax-Free Rollovers. The Internal Revenue Code (the “Code”) permits the taxable portion of funds to be transferred in a tax-free rollover from a qualified retirement plan, tax-deferred annuity plan or governmental 457(b) plan to an IRA Contract if certain conditions are met, and if the indirect rollover of assets is completed within 60 days after the distribution from the qualified plan is received by the plan participant. A direct rollover of funds may avoid a 20% federal tax withholding generally applicable to qualified plans, tax-deferred annuity plan, or governmental 457(b) plan distributions and the 60-day rollover rules. In addition, not more frequently than once every twelve months, an individual may execute one tax-free indirect rollover from one IRA to another, subject to the 60-day limitation and other requirements. The once-per-year limitation on rollovers does not apply to direct transfers of funds between IRA custodians or trustees or to Roth IRA conversions.

SIMPLIFIED EMPLOYEE PENSION (SEP) PLANS AND SALARY REDUCTION SIMPLIFIED EMPLOYEE PENSION (SAR/SEP) PLANS

Contributions . Under Section 408(k) of the Code, employers may establish a type of IRA plan referred to as a simplified employee pension plan (SEP). Employer contributions to a SEP cannot exceed the lesser of 25% of employee compensation or $61,000 for 2022.

Employees of certain small employers may have contributions made to the salary reduction simplified employee pension plan (SAR/SEP) on their behalf on a salary reduction basis. The amount that an employee chooses to defer and contribute to the SAR/SEP is referred to as an elective deferral.

These elective deferrals are subject to the same cap as elective deferrals to IRC Section 401(k) plans, see table below. In addition to the elective deferrals, SAR/SEP may permit additional elective deferrals by individuals age 50 or over, referred to as “catch-up contributions”.

No new SAR/SEP are permitted after 1996 for any employer, but those in effect prior to 1997 may continue to operate, receive contributions, and add new employees.

Salary Reduction Simplified Employee Pension Plan (SAR/SEP)
Year	Elective Deferral	Catch-up Contribution
2021	$19,500	$6,500
2022	$20,500	$6,500

Taxation of Distributions. Generally, distribution payments from SEPs and SAR/SEPs are subject to the same distribution rules described above for traditional IRAs.

6

Required Distributions. SEPs and SAR/SEPs are subject to the same minimum required distribution rules described above for traditional IRAs.

Tax-Free Rollovers. Generally, rollovers and direct transfers may be made to and from SEPs and SAR/SEPs in the same manner as described above for traditional IRAs, subject to the same conditions and limitations.

SAVINGS INCENTIVE MATCH PLANS FOR EMPLOYEES (SIMPLE IRA)

Contributions. Under Section 408(p) of the Code, employers may establish a type of IRA plan known as a SIMPLE IRA. Employees may have contributions made to the SIMPLE IRA on a salary reduction basis. The amount that an employee chooses to defer and contribute to the SIMPLE IRA is referred to as an elective deferral.

These elective deferrals cannot exceed the amounts shown in the chart. In addition to the elective deferrals, SIMPLE IRA may permit additional elective deferrals by individuals age 50 or over, referred to as “catch-up contributions” in an amount equal to $3,000 for 2022.

Elective contribution amounts made under the salary reduction portions (i.e., those subject to the $14,000 limit in 2022) of a SIMPLE IRA plan are counted in the overall limit on elective deferrals by any individual. For example, if in 2022, an individual under age 50 defers the maximum of $14,000 to a SIMPLE IRA of one employer and also participates in a 401(k) plan of another employer, they would be limited to an elective deferral of $6,500 ($20,500 - $14,000) to the 401(k) plan for 2022.

The employer generally must match either 100% of the employee’s elective deferral, up to 3% of the employee’s compensation (subject to certain exceptions) or fixed nonelective contributions of 2% of compensation of all eligible employees.

Savings Incentive Match Plan for Employees (SIMPLE IRA)
Year	Elective Deferral	Catch-up Contribution	401(k) Elective Deferral
2021	$13,500	$3,000	$19,500
2022	$14,000	$3,000	$20,500

Taxation of Distributions. Generally, distribution payments from SIMPLE IRAs are subject to the same distribution rules described above for traditional IRAs, except that distributions made within two years of the date of an employee’s first participation in a SIMPLE IRA of an employer are subject to a 25% penalty tax instead of the 10% penalty tax discussed previously.

Required Distributions. SIMPLE IRAs are subject to the same minimum required distribution rules described above for traditional IRAs.

Tax-Free Rollovers. Direct transfers may be made among SIMPLE IRAs in the same manner as described above for IRAs, subject to the same conditions and limitations. Rollovers from SIMPLE IRAs to other types of IRAs and certain qualified plans are permitted after two years have elapsed from the date of an employee’s first participation in a SIMPLE IRA of the employer. Rollovers to SIMPLE IRAs from other plans are permitted after two years of participation in the SIMPLE IRA.

ROTH INDIVIDUAL RETIREMENT ANNUITIES (ROTH IRA)

Contribution. Under Section 408A of the Code, individuals may contribute to a Roth IRA on his/her own behalf up to the lesser of maximum annual contribution limit as shown in the chart or 100% of compensation. In addition, the contribution must be reduced by the amount of any contributions made to other IRAs for the benefit of the same individual.

Roth IRA - Maximum Annual Contribution
Year	Individual Roth IRA	Catch-up Contribution
2021	$6,000	$1,000
2022	$6,000	$1,000

For succeeding years, individual Roth IRA limits are indexed for cost-of-living.

Individuals age 50 or over are also permitted to make additional “catch-up” contributions. The additional contribution is $1,000 for 2021 and 2022.

7

For 2022, the maximum contribution is phased out for single taxpayers with adjusted gross income between $129,000 and $144,000 and for joint filers with adjusted gross income between $204,000 and $214,000 (see chart below).

Modified Adjusted Gross Income Limits - 2022
Single/Head of Household	Married Filing Joint	ROTH IRA Contribution
< $129,000	< $204,000	Full Contribution
> $125,000 but < $144,000	> $198,000 but < $214,000	Partial Contribution*
> $144,000	> $214,000	No Contribution

*    Those entitled to only a partial contribution should check with a tax advisor to determine the allowable contribution amount.

A person whose filing status is “married, filing separately” may not make a full Roth IRA contribution, unless the couple is separated and have been living apart for the entire year. Only a partial contribution is allowed if your Modified Adjusted Gross Income is less than $10,000.

Taxation of Distribution. Qualified distributions are received income-tax free by the Roth IRA owner, or beneficiary in case of the Roth IRA owner’s death. A qualified distribution is any distribution made after five years if the IRA owner is over age 59½, dies, becomes disabled, or uses the funds for first-time home purchase at the time of distribution. The five-year period for owner contributions begins January 1 of the year the first contribution is made to any Roth IRA. The five-year period for converted amounts begins from January 1 of the year of the conversion for the purposes of the 10% penalty tax.

Required Distributions. Roth IRAs are not subject to lifetime minimum required distributions. Roth IRAs are subject to the same post-death minimum required distribution rules described above for IRAs.

In our opinion, the financial statements present fairly, in all material respects, the financial position of each subaccount as of December 31, 2021, the results of its operations and changes in its net assets for each of the periods indicated in the Appendix, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Separate Account’s management. Our responsibility is to express an opinion on each of the subaccounts’ financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Separate Account in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2021,by correspondence with the fund companies or their transfer agents, as applicable. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Notes to Financial Statements

December 31, 2021

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements and accompanying notes of Separate Account B in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported and disclosed. These estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed in the financial statements and accompanying notes.

The outbreak of the novel coronavirus (“COVID-19”) in many countries continues to adversely impact global commercial activity and has contributed to significant volatility in financial markets. These events present material uncertainty and risk with respect to the Separate Account performance and financial results.

Investments

Investments are stated at the closing net asset value (“NAV”) per share on December 31, 2021. Net realized capital gains and losses on sales of investments are determined on the basis of specific identification under the first-in, first-out method. Investment transactions are accounted for on a trade date basis. Dividends and realized gains (losses) on investments are recognized on an accrual basis as of the ex-dividend date and are automatically reinvested in shares of the funds on the payable date.

Fair Value Measurements

    Fair value is defined 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). The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three levels.The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety considering factors specific to the asset or liability.

•Level 1 – Fair values are based on unadjusted quoted prices in active markets for identical assets or liabilities.

•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.

•Level 3 – Fair values are based on at least one significant unobservable input for the asset or liability.

    All investments of the open-end management investment companies listed above represent investments in mutual funds for which a daily NAV is calculated and published. Therefore, all investments are reflected in Level 1 of the fair value hierarchy.

2. Expenses and Related Party Transactions

Principal Life is compensated for the following expenses:

Bankers Flexible Annuity contracts – Mortality and expense risks assumed by Principal Life are compensated for by a daily charge resulting in a reduction of the unit value equivalent to an annual rate of 0.48% of the asset value of each contract.

During the year ended December 31, 2021, investment advisory and management fees were paid indirectly to Principal Global Investors, LLC (“Manager”) (wholly owned indirectly by Principal Financial Services, Inc.) in its capacity as advisor to Principal Variable Contracts Funds, Inc. These fees are computed at an annual percentage rate of each division’s average daily net assets. A portion of the management fee is paid by the Manager to the sub-advisor of each of the divisions, some of which are affiliates of the Manager. The annual rate paid by the SAM Portfolios is based upon the aggregate average daily net assets (“aggregate net assets”) of the SAM Portfolios. The investment advisory and management fee schedule for the SAM Portfolios is 0.25% of aggregate net assets up to the first $1 billion and 0.20% of aggregate net assets over $1 billion. The Principal LifeTime Accounts do not pay investment advisory and management fees.

6. Financial Highlights

Principal Life sells a number of variable annuity products, which have unique combinations of features and fees that are charged against the contractholder’s account balance. Differences in the fee structures result in a variety of unit values, expense ratios and total returns.

Separate Account B has presented the following disclosures for 2021, 2020, 2019, 2018 and 2017 in accordance with the American Institute of Certified Public Accountants Audit and Accounting Guide for Investment Companies. The following table was developed by determining which products issued by Principal Life have the lowest and highest total return. Only product designs within each division that had accumulation units outstanding during the respective periods were considered when determining the lowest and highest total return. The summary may not reflect the minimum and maximum contract charges offered by Principal Life as the contractholder may not have selected all available and applicable contract options as discussed in Note 2. Additionally, the unit values, expense ratios and total returns are presented as a range of minimum to maximum values. Therefore, some individual contract unit values may not be within the ranges presented.

(*)	We identified immaterial corrections in certain divisions related to the unit fair value corresponding to the low/high expense ratios, investment income ratio and total return corresponding to the low/high expense ratios, which were corrected in 2021.
(1)	These amounts represent the dividends, excluding distributions of capital gains, received by the division from the underlying mutual fund, net of management fees assessed by the fund manager, divided by the average net assets. These ratios exclude those expenses, such as mortality and expense charges, that result in direct reductions in the unit values. The recognition of investment income by the division is affected by the timing of the declaration of dividends by the underlying fund in which the divisions invest. These ratios are annualized for periods less than one year.
(2)	These ratios represent the annualized contract expenses of the separate account, consisting primarily of mortality and expense charges, for each period indicated. The ratios include only those expenses that result in a direct reduction to unit values. Charges made directly to contractholder accounts through the redemption of units and expenses of the underlying fund are excluded.
(3)	These amounts represent the total return for the periods indicated, including changes in the value of the underlying fund, and reflect deductions for all items included in the expense ratio. The total return does not include any expenses assessed through the redemption of units; inclusion of these expenses in the calculation would result in a reduction in the total return presented. Investment options with a date notation indicate the effective date of that investment option in the variable account. For purposes of the total return calculation the beginning unit value is typically equal to an investment option with a similar expense structure and if no such similar investment option exists, a beginning unit value of ten would typically be used. The total return is calculated for the period indicated or from the effective date through the end of the reporting period. Total returns have not been annualized for periods less than one year. These percentages represent the range of total returns available as of the report date and correspond with the expense ratio lowest to highest.

APPENDIX B - Principal Life Insurance Company Financials

B-1

Report of Independent Auditors

The Board of Directors and Stockholder of

Principal Life Insurance Company

Opinion

We have audited the consolidated financial statements of Principal Life Insurance Company (the Company), which comprise the consolidated statements of financial position as of December 31, 2021 and 2020, and the related consolidated statements of operations, comprehensive income, stockholder’s equity and cash flows for the years then ended, and the related notes (collectively referred to as the “financial statements”).

In our opinion, the accompanying financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

Basis for Opinion

We conducted our audits in accordance with auditing standards generally accepted in the United States of America (GAAS). Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Financial Statements section of our report. We are required to be independent of the Company and to meet our other ethical responsibilities in accordance with the relevant ethical requirements relating to our audits. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Responsibilities of Management for the Financial Statements

Management is responsible for the preparation and fair presentation of the financial statements in accordance with accounting principles generally accepted in the United States of America, and for the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free of material misstatement, whether due to fraud or error.

In preparing the financial statements, management is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year after the date that the financial statements are available to be issued.

Auditor’s Responsibilities for the Audit of the Financial Statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free of material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance but is not absolute assurance and therefore is not a guarantee that an audit conducted in accordance with GAAS will always detect a material misstatement when it exists. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Misstatements are considered material if there is a substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based on the financial statements.

B-2

In performing an audit in accordance with GAAS, we:

•Exercise professional judgment and maintain professional skepticism throughout the audit.

•Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, and design and perform audit procedures responsive to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements.

•Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control. Accordingly, no such opinion is expressed.

•Evaluate the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluate the overall presentation of the financial statements.

•Conclude whether, in our judgment, there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for a reasonable period of time.

We are required to communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit, significant audit findings, and certain internal control-related matters that we identified during the audit.

Required Supplementary Information

Accounting principles generally accepted in the United States require that the Claims Development and Claim Duration and Payout information presented as unaudited within the Short-Duration Contracts disclosure on page 56-60 be presented to supplement the financial statements. Such information is the responsibility of management and, although not a part of the financial statements, is required by the Financial Accounting Standards Board who considers it to be an essential part of financial reporting for placing the financial statements in an appropriate operational, economic, or historical context. We have applied certain limited procedures to the required supplementary information in accordance with auditing standards generally accepted in the United States of America, which consisted of inquiries of management about the methods of preparing the information and comparing the information for consistency with management’s responses to our inquiries, the financial statements, and other knowledge we obtained during our audit of the financial statements. We do not express an opinion or provide any assurance on the information because the limited procedures do not provide us with sufficient evidence to express an opinion or provide any assurance.

Principal Life Insurance Company
Notes to Consolidated Financial StatementsDecember 31, 2021

1. Nature of Operations and Significant Accounting Policies

Description of Business

Principal Life Insurance Company (“PLIC”) along with its consolidated subsidiaries is a diversified financial services organization offering businesses, individuals and institutional clients a wide range of financial products and services, including retirement and insurance in the U.S. We are a direct wholly owned subsidiary of Principal Financial Services, Inc. (“PFS”), which in turn is a direct wholly owned subsidiary of Principal Financial Group, Inc. (“PFG”).

Basis of Presentation

The accompanying consolidated financial statements include the accounts of PLIC and all other entities in which we directly or indirectly have a controlling financial interest as well as those variable interest entities (“VIEs”) in which we are the primary beneficiary. The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). All significant intercompany accounts and transactions have been eliminated.

Uncertainties, including those associated with the novel coronavirus (“COVID-19”), may impact our business, results of operations, financial condition and liquidity. Our use of estimates and assumptions affect amounts reported and disclosed and includes, but is not limited to, the fair value of investments in the absence of quoted market values, investment impairments and valuation allowances, the fair value of derivatives, deferred acquisition costs (“DAC”) and other actuarial balances, the liability for future policy benefits and claims, the value of other postretirement benefits and accounting for income taxes and the valuation of deferred tax assets. Our estimates and assumptions could change in the future as more information becomes known about the impact of COVID-19. Our results of operations and financial condition may also be impacted by other uncertainties including evolving regulatory, legislative and standard-setter accounting interpretations and guidance.

Certain reclassifications have been made to prior periods relating to the significant components of net deferred income taxes to conform to the current presentation. See Note 11, Income Taxes, under the caption “Net Deferred Income Taxes.”

We evaluated subsequent events through March 10, 2022, which was the date our consolidated financial statements were issued.

Consolidation

We have relationships with various special purpose entities and other legal entities that must be evaluated to determine if the entities meet the criteria of a VIE or a voting interest entity (“VOE”). This assessment is performed by reviewing contractual, ownership and other rights, including involvement of related parties, and requires use of judgment. First, we determine if we hold a variable interest in an entity by assessing if we have the right to receive expected losses and expected residual returns of the entity. If we hold a variable interest, then the entity is assessed to determine if it is a VIE. An entity is a VIE if the equity at risk is not sufficient to support its activities, if the equity holders lack a controlling financial interest or if the entity is structured with non-substantive voting rights. In addition to the previous criteria, if the entity is a limited partnership or similar entity, it is a VIE if the limited partners do not have the power to direct the entity’s most significant activities through substantive kick-out rights or participating rights. A VIE is evaluated to determine the primary beneficiary. The primary beneficiary of a VIE is the enterprise with (1) the power to direct the activities of a VIE that most significantly impact the entity's economic performance and (2) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. When we are the primary beneficiary, we are required to consolidate the entity in our financial statements. We reassess our involvement with VIEs on a quarterly basis. For further information about VIEs, refer to Note 4, Variable Interest Entities.

If an entity is not a VIE, it is considered a VOE. VOEs are generally consolidated if we own a greater than 50% voting interest. If we determine our involvement in an entity no longer meets the requirements for consolidation under either the VIE or VOE models, the entity is deconsolidated. Entities in which we have management influence over the operating and financing decisions but are not required to consolidate, other than investments accounted for at fair value under the fair value option, are reported using the equity method.

Recent Accounting Pronouncements

Description	Date of adoption	Effect on our consolidated financial statements or other significant matters
Standards not yet adopted:
Targeted improvements to the accounting for long-duration insurance contracts This authoritative guidance updates certain requirements in the accounting for long-duration insurance and annuity contracts. 1.The assumptions used to calculate the liability for future policy benefits on traditional and limited-payment contracts will be reviewed and updated periodically. Cash flow assumptions will be reviewed at least annually and updated when necessary with the impact recognized in net income. Discount rate assumptions are prescribed as the current upper-medium grade (low credit risk) fixed income instrument yield and will be updated quarterly with the impact recognized in other comprehensive income (“OCI”). 2.Market risk benefits, which are contracts or contract features that provide protection to the policyholder from capital market risk and expose us to other-than-nominal capital market risk, are measured at fair value. The periodic change in fair value is recognized in net income with the exception of the periodic change in fair value related to our own nonperformance risk, which is recognized in OCI. 3.DAC and other actuarial balances for all insurance and annuity contracts will be amortized on a constant basis over the expected term of the related contracts. 4.Additional disclosures are required, including disaggregated rollforwards of significant insurance liabilities and other account balances as well as disclosures about significant inputs, judgments, assumptions and methods used in measurement. The guidance for the liability for future policy benefits for traditional and limited-payment contracts and DAC will be applied on a modified retrospective basis; that is, to contracts in force as of the beginning of the earliest period presented based on their existing carrying amounts. An entity may elect to apply the changes retrospectively. The guidance for market risk benefits will be applied retrospectively. Early adoption is permitted.	January 1, 2023	Our implementation and evaluation process to date includes, but is not limited to the following: •identifying and documenting contracts and contract features in scope of the guidance; •identifying the actuarial models, systems and processes to be updated; •evaluating and selecting our systems solutions for implementing the new guidance; •building models and evaluating preliminary output as models are developed; •evaluating and finalizing our key accounting policies; •assessing the impact to our chart of accounts; •developing format and content of new disclosures; •conducting financial dry runs using model output and updated chart of accounts; •evaluating transition requirements and impacts and •establishing and documenting appropriate internal controls. This guidance will significantly change how we account for many of our insurance and annuity products. As we progress through our implementation, we will be able to better assess the impact to our consolidated financial statements.

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2021

Description	Date of adoption	Effect on our consolidated financial statements or other significant matters
Standards adopted:
Simplifying the accounting for income taxes This authoritative guidance simplifies the accounting for income taxes by removing certain exceptions, including exceptions related to the incremental approach for intraperiod tax allocation, calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. Also, the guidance clarifies the accounting for franchise taxes, transactions that result in a step-up in the tax basis of goodwill and enacted changes in tax laws or rates. It specifies that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements, although an entity may elect to do so. The guidance will be applied based on varying transition methods defined by amendment. Early adoption is permitted.	January 1, 2021	This guidance did not have a material impact on our consolidated financial statements.
Facilitation of the effects of reference rate reform on financial reporting This authoritative guidance provides optional expedients and exceptions for contracts and hedging relationships affected by reference rate reform. An entity may elect not to apply certain modification accounting requirements to contracts affected by reference rate reform and instead account for the modified contract as a continuation of the existing contract. Also, an entity may apply optional expedients to continue hedge accounting for hedging relationships in which the critical terms change due to reference rate reform. This guidance eases the financial reporting impacts of reference rate reform on contracts and hedging relationships and is effective until December 31, 2022.	March 12, 2020	We adopted the guidance upon issuance prospectively and elected the applicable optional expedients and exceptions for contracts and hedging relationships impacted by reference rate reform through December 31, 2022. The guidance did not have an impact on our consolidated financial statements upon adoption.
Goodwill impairment testing This authoritative guidance simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 (which measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill to the carrying amount of that goodwill) from the goodwill impairment test. A goodwill impairment loss will be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary.	January 1, 2020	This guidance reduces complexity and costs associated with performing a Step 2 test, should one be needed in the future. This guidance did not have a material impact on our consolidated financial statements at adoption.
Credit losses This authoritative guidance requires entities to use a current expected credit loss (“CECL”) model to measure impairment for most financial assets that are not recorded at fair value through net income. Under the CECL model, an entity will estimate lifetime expected credit losses considering available relevant information about historical events, current conditions and reasonable and supportable forecasts. The CECL model does not apply to available-for-sale debt securities; however, the credit loss calculation and subsequent recoveries for available-for-sale securities are required to be recorded through an allowance. This guidance also expands the required credit loss disclosures.	January 1, 2020	We adopted the guidance using the modified retrospective approach. A cumulative effect adjustment of $6.7 million was recorded as a decrease to retained earnings. We recorded an offsetting increase in the allowance for credit loss for mortgage loans, reinsurance recoverables and commitments and a decrease for deferred tax impacts. See Note 5, Investments, for further details.

Notes to Consolidated Financial Statements – (continued)December 31, 2021

Description	Date of adoption	Effect on our consolidated financial statements or other significant matters
Implementation costs in a cloud computing arrangement that is a service contract This authoritative guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This guidance can be applied either retrospectively or prospectively and early adoption is permitted.	January 1, 2019	The effective date of the guidance was January 1, 2020; however, we elected to early-adopt this guidance on a prospective basis, effective January 1, 2019. This guidance did not have a material impact on our consolidated financial statements.
Nonemployee share-based payment accounting This authoritative guidance simplifies the accounting for share-based payments to nonemployees by generally aligning it with the accounting for share-based payments to employees. Under the guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date, where previously the measurement was fixed at performance completion date. The guidance will be applied to equity-classified nonemployee awards for which a measurement date has not been established as of the date of adoption.	January 1, 2019	This guidance did not have a material impact on our consolidated financial statements.
Leases This authoritative guidance requires lessee recognition of lease assets and lease liabilities on the consolidated statements of financial position. The concept of an operating lease, where the lease assets and liabilities are not reported on the consolidated statements of financial position, is eliminated under the new guidance. For lessors, the guidance modifies lease classification criteria and accounting for certain types of leases. Other key aspects of the guidance relate to the removal of the current real estate-specific guidance and new presentation and disclosure requirements. Lessees and lessors are required to recognize and measure leases using a modified retrospective approach, which includes certain optional practical expedients that may be elected. We elected the alternative transition method, which allows entities to initially apply the new standard at the adoption date and recognize a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption.	January 1, 2019	We adopted the guidance using the modified retrospective approach. A cumulative effect adjustment of $4.0 million was recorded as an increase to retained earnings. See Note 13, Contingencies, Guarantees, Indemnifications and Leases, for further details.
Targeted improvements to accounting for hedging activities This authoritative guidance updated certain recognition and measurement requirements for hedge accounting. The objective of the guidance is to more closely align the economics of a company’s risk management activities in its financial results and reduce the complexity of applying hedge accounting. The updates included the expansion of hedging strategies that are eligible for hedge accounting, elimination of the separate measurement and reporting of hedge ineffectiveness, presentation of the changes in the fair value of the hedging instrument in the same consolidated statement of operations line as the earnings effect of the hedged item and simplification of hedge effectiveness assessments. This guidance also included new disclosures.	January 1, 2019	This guidance did not have a material impact on our consolidated financial statements. See Note 6, Derivative Financial Instruments, for further details.

Description	Date of adoption	Effect on our consolidated financial statements or other significant matters
Premium amortization on purchased callable debt securities This authoritative guidance applies to entities that hold certain non-contingently callable debt securities, where the amortized cost basis is at a premium to the price repayable by the issuer at the earliest call date. Under the guidance the premium will be amortized to the first call date.	January 1, 2019	This guidance did not have a material impact on our consolidated financial statements.

When we adopt new accounting standards, we have a process in place to perform a thorough review of the pronouncement, identify the financial statement and system impacts and create an implementation plan among our impacted business units to ensure we are compliant with the pronouncement on the date of adoption. This includes having effective processes and controls in place to support the reported amounts. Each of the standards listed above is in varying stages in our implementation process based on its issuance and adoption dates. We are on track to implement guidance by the respective effective dates.

Use of Estimates in the Preparation of Financial Statements

    The preparation of our consolidated financial statements and accompanying notes requires management to make estimates and assumptions that affect the amounts reported and disclosed. These estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed in the consolidated financial statements and accompanying notes. The most critical estimates include those used in determining:

•the fair value of investments in the absence of quoted market values;

•investment impairments and valuation allowances;

•the fair value of and accounting for derivatives;

•the DAC and other actuarial balances where the amortization is based on estimated gross profits (“EGPs”);

•the liability for future policy benefits and claims;

•the value of our other postretirement benefit obligation and

•accounting for income taxes and the valuation of deferred tax assets.

A description of such critical estimates is incorporated within the discussion of the related accounting policies that follow. In applying these policies, management makes subjective and complex judgments that frequently require estimates about matters that are inherently uncertain. Actual results could differ from these estimates.

Closed Block

    We operate a closed block (“Closed Block”) for the benefit of individual participating dividend-paying policies in force at the time of the 1998 mutual insurance holding company (“MIHC”) formation. See Note 7, Closed Block, for further details.

Cash and Cash Equivalents

    Cash and cash equivalents include cash on hand, money market instruments and other debt issues with a maturity date of three months or less when purchased.

Investments

Fixed maturities include bonds, asset-backed securities (“ABS”), redeemable preferred stock and certain non-redeemable preferred securities. Equity securities include mutual funds, common stock and non-redeemable preferred stock. We classify fixed maturities as either available-for-sale or trading at the time of the purchase and, accordingly, carry them at fair value. Equity securities are also carried at fair value. See Note 15, Fair Value Measurements, for methodologies related to the determination of fair value. Unrealized gains and losses related to fixed maturities, available-for-sale, excluding those in fair value hedging relationships, are reflected in stockholder’s equity, net of adjustments associated with DAC and related actuarial balances, derivatives in cash flow hedge relationships and applicable income taxes. Mark-to-market adjustments on fixed maturities, trading are reflected in net realized capital gains (losses). Unrealized gains and losses related to hedged portions of fixed maturities, available-for-sale in fair value hedging relationships are reflected in net investment income. Mark-to-market adjustments related to certain securities carried at fair value with an investment objective to realize economic value through mark-to-market changes are reflected in net investment income.

B-13

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2021

The amortized cost of fixed maturities includes cost adjusted for amortization of premiums and discounts, computed using the interest method. The amortized cost of fixed maturities, available-for-sale is adjusted for changes in fair value of the hedged portions of securities in fair value hedging relationships and excludes accrued interest receivable. Accrued interest receivable is reported in accrued investment income on the consolidated statements of financial position. Beginning in 2020, fixed maturities, available-for-sale are subject to an allowance for credit loss and changes in the allowance are reported in net income as a component of net realized capital gains (losses). Prior to 2020, the amortized cost of fixed maturities classified as available-for-sale was adjusted for declines in value that were other than temporary. Prior to 2020, impairments in value deemed to be other than temporary were primarily reported in net income as a component of net realized capital gains (losses), with noncredit impairment losses for certain fixed maturities, available-for-sale reported in OCI. Interest income, as well as prepayment fees and the amortization of the related premium or discount, is reported in net investment income.For loan-backed and structured securities, we recognize income using a constant effective yield based on currently anticipated cash flows.

Commercial and residential mortgage loans are generally reported at cost adjusted for amortization of premiums and accrual of discounts, computed using the interest method and net of valuation allowances. Amortized cost excludes accrued interest receivable. Interest income is accrued on the principal amount of the loan based on the loan’s contractual interest rate. Interest income, as well as prepayment of fees and the amortization of the related premium or discount, is reported in net investment income on the consolidated statements of operations. Accrued interest receivable is reported in accrued investment income on the consolidated statements of financial position. Any changes in the loan valuation allowances are reported in net realized capital gains (losses) on the consolidated statements of operations. See Note 5, Investments, for further details of our valuation allowance.    

Our commercial and residential mortgage loan portfolios can include loans that have been modified. We assess loan modifications on a case-by-case basis to evaluate whether a troubled debt restructuring (“TDR”) has occurred. In response to COVID-19, the Coronavirus Aid, Relief and Economic Security Act, which was subsequently amended by the Consolidated Appropriations Act, 2021, (collectively the “CARES Act”) provides a temporary suspension of TDR accounting for certain COVID-19 related loan modifications where the loan was not more than 30 days past due as of December 31, 2019. We elected the TDR relief in the CARES Act beginning in the second quarter of 2020. The CARES Act TDR relief does not apply to modifications completed subsequent to the earlier of 60 days after the national emergency related to COVID-19 ends, or January 1, 2022. In addition, the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus (As Revised on April 7, 2020) (“Interagency Statement”) provides additional guidance to determine if a short-term COVID-19 related loan modification is a TDR. We consider the CARES Act and the Interagency Statement when assessing loan modifications to determine whether a TDR has occurred. See Note 5, Investments, under the caption “Mortgage Loan Modifications” for further details.

Real estate investments are reported at cost less accumulated depreciation. The initial cost bases of properties acquired through loan foreclosures are the lower of the fair market values of the properties at the time of foreclosure or the outstanding loan balance. Buildings and land improvements are generally depreciated on the straight-line method over the estimated useful life of improvements and tenant improvement costs are depreciated on the straight-line method over the term of the related lease. We recognize impairment losses for properties when indicators of impairment are present and a property's expected undiscounted cash flows are not sufficient to recover the property's carrying value. In such cases, the cost basis of the property is reduced to fair value. Real estate expected to be disposed is carried at the lower of cost or fair value, less cost to sell, with valuation allowances established accordingly and depreciation no longer recognized. The carrying amount of real estate held for sale was $74.2 million and $1.2 million as of December 31, 2021 and 2020, respectively. Any impairment losses and any changes in valuation allowances are reported in net income.

Net realized capital gains and losses on sales of investments are determined on the basis of specific identification. In general, in addition to realized capital gains and losses on investment sales and periodic settlements on derivatives not designated as hedges, we report gains and losses related to the following in net realized capital gains (losses) on the consolidated statements of operations: mark-to-market adjustments on equity securities, mark-to-market adjustments on fixed maturities, trading, mark-to-market adjustments on certain investment funds, mark-to-market adjustments on derivatives not designated as hedges, cash flow hedge gains (losses) when the hedged item impacts realized capital gains (losses), changes in the valuation allowance for fixed maturities, available-for-sale and certain financing receivables, impairments of real estate held for investment, impairments of equity method investments and, prior to 2020, other-than-temporary impairments of securities and subsequent realized recoveries. Investment gains and losses on sales of certain real estate held for sale due to investment strategy and mark-to-market adjustments on certain securities carried at fair value with an investment objective to realize economic value through mark-to-market changes are reported as net investment income and are excluded from net realized capital gains (losses).

    Policy loans and certain other investments are reported at cost. Interests in unconsolidated entities, joint ventures and partnerships are generally accounted for using the equity method. We have other investments reported at fair value or for which the fair value option has been elected in prior periods. See Note 15, Fair Value Measurements, for detail on these investments.

Derivatives

Overview

Derivatives are financial instruments whose values are derived from interest rates, foreign exchange rates, financial indices or the values of securities. Derivatives generally used by us include swaps, options, futures and forwards. Derivative positions are either assets or liabilities in the consolidated statements of financial position and are measured at fair value, generally by obtaining quoted market prices or through the use of pricing models. See Note 15, Fair Value Measurements, for policies related to the determination of fair value. Fair values can be affected by changes in interest rates, foreign exchange rates, financial indices, values of securities, credit spreads, and market volatility and liquidity.

Accounting and Financial Statement Presentation

We designate derivatives as either:

(a)    a hedge of the exposure to changes in the fair value of a recognized asset or liability or an unrecognized firm commitment, including those denominated in a foreign currency (“fair value hedge”);

(b)    a hedge of a forecasted transaction or the exposure to variability of cash flows to be received or paid related to a recognized asset or liability, including those denominated in a foreign currency (“cash flow hedge”) or

(c)    a derivative not designated as a hedging instrument.

    Our accounting for the ongoing changes in fair value of a derivative depends on the intended use of the derivative and the designation, as described above, and is determined when the derivative contract is entered into or at the time of redesignation. Hedge accounting is used for derivatives that are specifically designated in advance as hedges and that reduce our exposure to an indicated risk by having a high correlation between changes in the value of the derivatives and the items being hedged at both the inception of the hedge and throughout the hedge period. Cash flows associated with derivatives are included within operating and financing activities in the consolidated statements of cash flows.

Fair Value Hedges. When a derivative is designated as a fair value hedge and is determined to be highly effective, changes in its fair value, along with changes in the fair value of the hedged asset, liability or firm commitment attributable to the hedged risk, are reported in the same consolidated statements of operations line item that is used to report the earnings effect of the hedged item. For fair value hedges of fixed maturities, available-for-sale, these changes in fair value are reported in net investment income. A fair value hedge determined to be highly effective may still result in a mismatch between the change in the fair value of the hedging instrument and the change in the fair value of the hedged item attributable to the hedged risk. Certain fair value hedges use the last-of-layer method to hedge a designated amount (the "last layer") within a closed portfolio of prepayable assets that is expected to remain outstanding for the length of the hedging relationship and is not expected to be impacted by prepayments, defaults or other factors that affect the timing and amount of cash flows. Prepayment risk is excluded when measuring the change in fair value attributable to the hedged risk under the last-of-layer method.

    Cash Flow Hedges. When a derivative is designated as a cash flow hedge and is determined to be highly effective, changes in its fair value are recorded as a component of OCI. At the time the variability of cash flows being hedged impacts net income, the related portion of deferred gains or losses on the derivative instrument is reclassified and reported in net income.

    Non-Hedge Derivatives. If a derivative does not qualify or is not designated for hedge accounting, all changes in fair value are reported in net income without considering the changes in the fair value of the economically associated assets or liabilities.

    Hedge Documentation and Effectiveness Testing. At inception, we formally document all relationships between hedging instruments and hedged items, as well as our risk management objective and strategy for undertaking various hedge transactions. This process includes associating all derivatives designated as fair value or cash flow hedges with specific assets or liabilities on the consolidated statements of financial position or with specific firm commitments or forecasted transactions. Documentation of fair value hedges that use the last-of-layer method supports the expectation that the hedged last layer amount is anticipated to be outstanding at the end of the hedging relationship and includes expectations of prepayments, defaults or other factors that affect the timing and amount of cash flows. Effectiveness of the hedge is formally assessed at inception and throughout the life of the hedging relationship. Even if a hedge is determined to be highly effective, the hedge may still result in a mismatch between the change in the fair value of the hedging instrument and the change in the fair value of the hedged item attributable to the hedged risk.

B-15

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2021

    We use qualitative and quantitative methods to assess hedge effectiveness. Qualitative methods may include monitoring changes to terms and conditions and counterparty credit ratings. Quantitative methods may include statistical tests including regression analysis and minimum variance and dollar offset techniques. For last-of-layer method hedges, the assessment of hedge effectiveness includes confirming we expect the hedged last layer amount to be outstanding at the end of the hedging relationship.

    Termination of Hedge Accounting. We prospectively discontinue hedge accounting when (1) the criteria to qualify for hedge accounting is no longer met, e.g., a derivative is determined to no longer be highly effective in offsetting the change in fair value or cash flows of a hedged item; (2) the derivative expires, is sold, terminated or exercised or (3) we remove the designation of the derivative being the hedging instrument for a fair value or cash flow hedge.

    If it is determined that a derivative no longer qualifies as an effective hedge, the derivative will continue to be carried on the consolidated statements of financial position at its fair value, with changes in fair value recognized prospectively in net realized capital gains (losses). The asset or liability under a fair value hedge will no longer be adjusted for changes in fair value pursuant to hedging rules and the existing basis adjustment is amortized to the consolidated statements of operations line associated with the asset or liability. If a last-of-layer method hedging relationship is discontinued, the outstanding basis adjustment is allocated to the individual assets in the closed portfolio and those amounts are amortized consistent with the amortization of other discounts or premiums associated with those assets.

The component of AOCI related to discontinued cash flow hedges that are no longer highly effective is amortized to the consolidated statements of operations consistent with the net income impacts of the original hedged cash flows. If a cash flow hedge is discontinued because it is probable the hedged forecasted transaction will not occur, the deferred gain or loss is immediately reclassified from AOCI into net income.

    Embedded Derivatives. We purchase and issue certain financial instruments and products that contain a derivative that is embedded in the financial instrument or product. We assess whether this embedded derivative is clearly and closely related to the asset or liability that serves as its host contract. If we deem that the embedded derivative's terms are not clearly and closely related to the host contract, and a separate instrument with the same terms would qualify as a derivative instrument, the derivative is bifurcated from that contract and held at fair value on the consolidated statements of financial position, with changes in fair value reported in net income.

Contractholder and Policyholder Liabilities

    Contractholder and policyholder liabilities (contractholder funds, future policy benefits and claims and other policyholder funds) include reserves for investment contracts, individual and group annuities that provide periodic income payments, universal life insurance, variable universal life insurance, indexed universal life insurance, term life insurance, participating traditional individual life insurance, group dental and vision insurance, group critical illness, group accident, group short-term and long-term disability insurance, group life insurance, individual disability insurance and long-term care insurance. It also includes a provision for dividends on participating policies.

    Investment contracts are contractholders' funds on deposit with us and generally include reserves for pension and annuity contracts. Reserves on investment contracts are equal to the cumulative deposits less any applicable charges and withdrawals plus credited interest. Reserves for universal life, variable universal life and indexed universal life insurance contracts are equal to cumulative deposits less charges plus credited interest, which represents the account balances that accrue to the benefit of the policyholders.

We hold additional reserves on certain long-duration contracts where benefit features result in gains in early years followed by losses in later years; universal life, variable universal life and indexed universal life insurance contracts that contain no lapse guarantee features; and annuities with guaranteed minimum death benefits.

    Reserves for individual and group annuities that provide periodic income payments, nonparticipating term life insurance and disability income contracts are computed on a basis of assumed investment yield, mortality, morbidity and expenses, including a provision for adverse deviation, which generally varies by plan, year of issue and policy duration. Investment yield is based on our experience. Mortality, morbidity and withdrawal rate assumptions are based on our experience and are periodically reviewed against both industry standards and experience. For long-duration insurance contracts, significant changes in experience or assumptions may require us to provide for expected future losses on a product by establishing premium deficiency reserves. Premium deficiency reserves may also be established for short-duration contracts to provide for expected future losses.

    Reserves for participating life insurance contracts are based on the net level premium reserve for death and endowment policy benefits. This net level premium reserve is calculated based on dividend fund interest rates and mortality rates guaranteed in calculating the cash surrender values described in the contract.

B-16

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2021

    Participating business represented approximately 4%, 5% and 6% of our life insurance in force and 18%, 20% and 23% of the number of life insurance policies in force as of December 31, 2021, 2020 and 2019, respectively. Participating business represented approximately 26%, 30% and 31% of life insurance premiums for the years ended December 31, 2021, 2020 and 2019, respectively. The amount of dividends to policyholders is declared annually by our Board of Directors. The amount of dividends to be paid to policyholders is determined after consideration of several factors including interest, mortality, morbidity and other expense experience for the year and judgment as to the appropriate level of statutory surplus to be retained by us. At the end of the reporting period, we establish a dividend liability for the pro rata portion of the dividends expected to be paid on or before the next policy anniversary date.

    Some of our policies and contracts require payment of fees or other policyholder assessments in advance for services that will be rendered over the estimated lives of the policies and contracts. These payments are established as unearned revenue liabilities upon receipt and included in other policyholder funds in the consolidated statements of financial position. These unearned revenue reserves are amortized to net income over the estimated lives of these policies and contracts in relation to the emergence of EGPs.

Short-Duration Contracts

    We include the following group products in our short-duration insurance contracts disclosures: long-term disability (“LTD”), group life waiver, dental, vision, short-term disability (“STD”), critical illness, accident and group life.

Future policy benefits and claims include reserves for group life and disability insurance that provide periodic income payments. These reserves are computed using assumptions of mortality, morbidity and investment performance. These assumptions are based on our experience, industry results, emerging trends and future expectations. Future policy benefits and claims also include reserves for incurred but unreported group disability, dental, vision, critical illness, accident and life insurance claims. We recognize claims costs in the period the service was provided to our policyholders. However, claims costs incurred in a particular period are not known with certainty until after we receive, process and pay the claims. We determine the amount of this liability using actuarial methods based on historical claim payment patterns as well as emerging cost trends, where applicable, to determine our estimate of claim liabilities.

    We have defined claim frequency as follows for each short-duration product:

•LTD: Claim frequency is based on submitted reserve claim counts.

•Group Life Waiver: Claim frequency is based on submitted reserve claim counts, consistent with LTD.

•Dental and Vision: Claim frequency is based on the claim form, which may include one or more procedures.

•STD, Critical Illness and Accident: Claim frequency is based on submitted claims.

•Group Life: Claim frequency is based on submitted life claims (lives, not coverages).

We did not make any significant changes to our methodologies or assumptions used to calculate the liability for unpaid claims for short-duration contracts during 2021.

Liability for Unpaid Claims

    The liability for unpaid claims for both long-duration and short-duration contracts is an estimate of the ultimate net cost of reported and unreported losses not yet settled. This liability is estimated using actuarial analyses and case basis evaluations. Although considerable variability is inherent in such estimates, we believe the liability for unpaid claims is adequate. These estimates are continually reviewed and, as adjustments to this liability become necessary, such adjustments are reflected in net income. Our liability for unpaid claims does not include any allocated claim adjustment expenses.

We incur claim adjustment expenses for both long-duration and short-duration contracts that cannot be allocated to a specific claim. Our claim adjustment expense liability is estimated using actuarial analyses based on historical trends of expenses and expected claim runout patterns.

See Note 9, Insurance Liabilities, under the caption “Liability for Unpaid Claims” for further details.

Recognition of Premiums and Other Considerations, Fees and Other Revenues and Benefits

    Products with fixed and guaranteed premiums and benefits consist principally of whole life and term life insurance policies and individual disability income. Premiums from these products are recognized as premium revenue when due. Related policy benefits and expenses for individual life products are associated with earned premiums and result in the recognition of profits over the expected term of the policies and contracts.

B-17

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2021

    Immediate annuities with life contingencies include products with fixed and guaranteed annuity considerations and benefits and consist principally of group and individual single premium annuities with life contingencies. Annuity considerations from these products are recognized as premium revenue. However, the collection of these annuity considerations does not represent the completion of the earnings process, as we establish annuity reserves using estimates for mortality and investment assumptions, which include provision for adverse deviation as required by U.S. GAAP. We anticipate profits to emerge over the life of the annuity products as we earn investment income, pay benefits and release reserves.

    Group life, dental, vision, critical illness, accident and disability premiums are generally recorded as premium revenue over the term of the coverage. Certain group contracts contain experience premium refund provisions based on a pre-defined formula that reflects their claim experience. Experience premium refunds reduce revenue over the term of the coverage and are adjusted to reflect current experience. Related policy benefits and expenses are associated with earned premiums and result in the recognition of profits over the term of the policies and contracts. Fees for contracts providing claim processing or other administrative services are recorded as revenue over the period the service is provided.

    Universal life-type policies are insurance contracts with terms that are not fixed. Amounts received as payments for such contracts are not reported as premium revenues. Revenues for universal life-type insurance contracts consist of policy charges for the cost of insurance, policy initiation and administration, surrender charges and other fees that have been assessed against policy account values and investment income. Policy benefits and claims that are charged to expense include interest credited to contracts and benefit claims incurred in the period in excess of related policy account balances.

    Investment contracts do not subject us to significant risks arising from policyholder mortality or morbidity and consist primarily of guaranteed investment contracts (“GICs”), funding agreements and certain deferred annuities. Amounts received as payments for investment contracts are established as investment contract liability balances and are not reported as premium revenues. Revenues for investment contracts consist of investment income and policy administration charges. Investment contract benefits that are charged to expense include benefit claims incurred in the period in excess of related investment contract liability balances and interest credited to investment contract liability balances.

    Fees and other revenues are earned for administrative services performed including recordkeeping, trust and custody and reporting services for retirement savings plans, insurance companies, endowments and other financial institutions and other products. Fees and other revenues received for performance of administrative services are recognized as revenue when earned, typically when the service is performed.

Deferred Acquisition Costs

Incremental direct costs of contract acquisition as well as certain costs directly related to acquisition activities (underwriting, policy issuance and processing, medical and inspection and sales force contract selling) for the successful acquisition of new and renewal insurance policies and investment contract business are capitalized to the extent recoverable. Commissions and other incremental direct costs for the acquisition of long-term service contracts are also capitalized to the extent recoverable. Maintenance costs and acquisition costs that are not deferrable are charged to net income as incurred.

DAC for universal life-type insurance contracts and certain investment contracts are amortized over the expected lifetime of the contracts in relation to EGPs or, in certain circumstances, estimated gross revenues (“EGR”). This amortization is adjusted in the current period when EGPs or EGRs are revised. EGRs include similar assumptions as the revenue component of EGPs and the changes of future estimates and reflection of actual experience and market conditions is done in the same manner as EGPs.

For individual variable universal life insurance, individual variable annuities and group annuities that have separate account U.S. equity investment options, we utilize a mean reversion methodology (reversion to the mean assumption), a common industry practice, to determine the future domestic equity market growth rate assumption used for the calculation of EGPs.

DAC for participating life insurance policies are amortized in proportion to estimated gross margins (“EGM”) rather than EGPs. EGMs include similar assumption items as EGPs. We stopped selling participating business in the early 2000s. Some products allow for underwritten death benefit increases and cost of living adjustments, resulting in a small amount of new DAC each year, and the amortization schedules are modified as appropriate.

DAC for non-participating term life insurance and individual disability policies are amortized over the premium-paying period of the related policies using assumptions consistent with those used in computing policyholder liabilities. Once these assumptions are made for a given policy or group of policies, they will not be changed over the life of the policy unless a loss recognition event occurs.

DAC on insurance policies and investment contracts are subject to recoverability testing at the time of policy issue and loss recognition testing on an annual basis, or when an event occurs that may warrant loss recognition. If loss recognition or impairment is necessary, DAC would be written off to the extent it is determined that future policy premiums and investment income or gross profits are not adequate to cover related losses and expenses.

B-18

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2021

DAC on short-duration group benefits policies are amortized over the estimated term of the underlying contracts.

Deferred Acquisition Costs on Internal Replacements

All insurance and investment contract modifications and replacements are reviewed to determine if the internal replacement results in a substantially changed contract. If so, the acquisition costs, sales inducements and unearned revenue associated with the new contract are deferred and amortized over the lifetime of the new contract. In addition, the existing DAC, sales inducement costs and unearned revenue balances associated with the replaced contract are written off. If an internal replacement results in a substantially unchanged contract, the acquisition costs, sales inducements and unearned revenue associated with the new contract are immediately recognized in the period incurred. In addition, the existing DAC, sales inducement costs or unearned revenue balance associated with the replaced contract is not written off, but instead is carried over to the new contract.

Long-Term Debt

    Long-term debt includes notes payable, nonrecourse mortgages and other debt with a maturity date greater than one year at the date of issuance. Current maturities of long-term debt are classified as long-term debt in our consolidated statements of financial position. Long-term debt is primarily recorded at the unpaid principal balance, net of unamortized discount, premium and issuance costs.

Reinsurance

We enter into reinsurance agreements with other companies in the normal course of business in order to limit losses and minimize exposure to significant risks. Assets and liabilities related to reinsurance ceded are reported on a gross basis. Premiums and expenses are reported net of reinsurance ceded. The cost of reinsurance related to long-duration contracts is accounted for over the life of the underlying reinsured policies using assumptions consistent with those used to account for the underlying policies. We are contingently liable with respect to reinsurance ceded to other companies in the event the reinsurer is unable to meet the obligations it has assumed. As of December 31, 2021 and 2020, we had $1,186.4 million and $1,094.9 million of net ceded reinsurance recoverables, respectively, which does not reflect potentially offsetting impacts of collateral. The reinsurance recoverable is recognized in premiums due and other receivables on the consolidated statements of financial position. As of December 31, 2021 and 2020, $578.0 million, or 95%, and $506.3 million, or 97%, were with our five largest ceded reinsurers, respectively.

    The effects of reinsurance on premiums and other considerations and policy and contract benefits were as follows:

		For the year ended December 31,
		2021			2020			2019
		(in millions)
Premiums and other considerations:
	Direct	$	5,364		$	6,489.9		$	8,035.7
	Ceded			(650.0)			(609.1)			(562.4)
Net premiums and other considerations		$	4,714		$	5,880.8		$	7,473.3
Benefits, claims and settlement expenses:
	Direct	$	7,147.6		$	8,362.2		$	9,743.9
	Ceded			(665.0)			(524.7)			(576.4)
Net benefits, claims and settlement expenses		$	6,482.6		$	7,837.5		$	9,167.5

Separate Accounts

The separate accounts are legally segregated and are not subject to the claims that arise out of any of our other business. The client, rather than us, directs the investments and bears the investment risk of these funds. The separate account assets represent the fair value of funds that are separately administered by us for contracts with equity, real estate and fixed income investments and are presented as a summary total within the consolidated statements of financial position. An equivalent amount is reported as separate account liabilities, which represent the obligation to return the monies to the client. We receive fees for mortality, withdrawal and expense risks, as well as administrative, maintenance and investment advisory services that are included in the consolidated statements of operations. Net deposits, net investment income and realized and unrealized capital gains and losses of the separate accounts are not reflected in the consolidated statements of operations. 

B-19

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2021

As of December 31, 2021 and 2020, the separate accounts included a separate account valued at $95.1 million and $80.4 million, respectively, which primarily included shares of PFG common stock that were allocated and issued to eligible participants of qualified employee benefit plans administered by us as part of the policy credits issued under Principal Mutual Holding Company’s 2001 demutualization. In the consolidated statements of financial position, the separate account shares are recorded at fair value and are reported as separate account assets with a corresponding separate account liability. Changes in fair value of the separate account shares are reflected in both the separate account assets and separate account liabilities and do not impact our results of operations.

Income Taxes

    Our ultimate parent, PFG, files a U.S. consolidated income tax return that includes us and all of our qualifying subsidiaries. In addition, PFG files income tax returns in all states and foreign jurisdictions in which it conducts business. PFG allocates income tax expenses and benefits to companies in the group generally based upon pro rata contribution of taxable income or operating losses. We are taxed at corporate rates on taxable income based on existing tax laws. Current income taxes are charged or credited to net income based upon amounts estimated to be payable or recoverable as a result of taxable operations for the current year. Deferred income taxes are provided for the tax effect of temporary differences in the financial reporting and income tax bases of assets and liabilities, net operating loss carryforwards and tax credit carryforwards using enacted income tax rates and laws. The effect on deferred income tax assets and deferred income tax liabilities of a change in tax rates is recognized in net income in the period in which the change is enacted. Subsequent to a change in tax rates and laws, any stranded tax effects remaining in AOCI will be released only if an entire portfolio is liquidated, sold or extinguished.

2. Related Party Transactions

Expense Reimbursements

We have entered into various related party transactions with our ultimate parent and its other affiliates. During the years ended December 31, 2021, 2020 and 2019, we received $647.2 million, $568.1 million and $607.1 million, respectively, of expense reimbursements from affiliated entities.

Cash Advance Agreement

We and our direct parent, PFS, are parties to a cash advance agreement, which allows us, collectively, to pool our available cash with other affiliates in order to more efficiently and effectively invest our cash. The cash advance agreement allows (i) us to advance cash to PFS in aggregate principal amounts not to exceed $1.0 billion, with such advanced amounts earning interest at the daily 30-day LIBOR rate (the “Internal Crediting Rate”); and (ii) PFS to advance cash to us in aggregate principal amounts not to exceed $1.0 billion, with such advance amounts paying interest at the Internal Crediting Rate plus 10 basis points to reimburse PFS for the costs incurred in maintaining short-term investing and borrowing programs. Under this cash advance agreement, we had a payable to PFS of $75.1 million and $56.4 million as of December 31, 2021 and 2020, respectively, and earned interest of $0.1 million, $0.0 million and $4.3 million during 2021, 2020 and 2019, respectively.

Reinsurance

We and an affiliated entity, Principal National Life Insurance Company, are parties to a reinsurance agreement to reinsure certain life insurance business. Under this agreement, we had an assumed reinsurance liability of $5,098.9 million and $4,523.5 million as of December 31, 2021 and 2020, respectively. In addition, we recognized premiums and other fees of $809.3 million, $749.3 million and $672.3 million for the years ended December 31, 2021, 2020 and 2019, respectively, associated with this agreement. Furthermore, we recognized expenses of $1,088.9 million, $1,038.9 million and $869.1 million for the years ended December 31, 2021, 2020 and 2019, respectively, associated with this agreement.

Notes Receivable

As of December 31, 2021, we had the following notes receivable from PFS related to the sale of interests in subsidiaries (1) a 10-year note with a par amount of $156.0 million, which bears interest at 2.87% with semi-annual principal and interest payments due in February and August each year and (2) a 10-year note with a par amount of $300.0 million, which bears interest at 2.885% with semi-annual principal and interest payments due in May and November each year. The carrying amount of the notes is included in premiums due and other receivables on the consolidated statements of financial position. We recorded interest income on these notes of $7.2 million, $8.5 million and $9.8 million for the years ended December 31, 2021, 2020 and 2019, respectively. Our ultimate parent, PFG, is a guarantor of the notes.

	2023			1.9
	2024			1.5
	2025			1.2

4. Variable Interest Entities

We have relationships with various types of entities which may be VIEs. Certain VIEs are consolidated in our financial results. See Note 1, Nature of Operations and Significant Accounting Policies, under the caption “Consolidation” for further details of our consolidation accounting policies. We did not provide financial or other support to investees designated as VIEs for the periods ended December 31, 2021 and December 31, 2020.

Consolidated Variable Interest Entities

Real Estate

We invest in several real estate limited partnerships and limited liability companies. The entities invest in real estate properties. Certain of these entities are VIEs based on the combination of our significant economic interest and related voting rights. We determined we are the primary beneficiary as a result of our power to control the entities through our significant ownership. Due to the nature of these real estate investments, the investment balance will fluctuate as we purchase and sell interests in the entities and as capital expenditures are made to improve the underlying real estate.

Residential Mortgage Loans

We invest in ABS trusts. The trusts issue various collateralized mortgage obligation certificates and purchase residential mortgage loans. The trusts are considered VIEs due to insufficient equity to sustain themselves. We concluded we are the primary beneficiary as we purchase substantially all of the certificates and have the obligation to absorb losses that could potentially be significant to the VIEs.

Assets and Liabilities of Consolidated Variable Interest Entities

The carrying amounts of our consolidated VIE assets, which can only be used to settle obligations of consolidated VIEs, and liabilities of consolidated VIEs for which creditors do not have recourse were as follows:

	December 31, 2021						December 31, 2020
	Total			Total			Total			Total
	assets			liabilities			assets			liabilities
	(in millions)
Real estate (1)	$	709.6		$	36.1		$	499		$	21.3
Residential mortgage loans (2)			1,263.2			20.3			319.8			—
Total	$	1,972.8		$	56.4		$	818.8		$	21.3

(1) The assets of the real estate VIEs primarily include real estate and cash. Liabilities primarily include other liabilities.

(2) The assets of the residential mortgage loans VIEs primarily include residential mortgage loans. The liabilities include other liabilities as of December 31, 2021.

Unconsolidated Variable Interest Entities

We hold a variable interest in a number of VIEs where we are not the primary beneficiary. Our investments in these VIEs are reported in fixed maturities, available-for-sale; fixed maturities, trading and other investments in the consolidated statements of financial position and are described below.

B-22

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2021

Unconsolidated VIEs include certain commercial mortgage-backed securities (“CMBS”), residential mortgage-backed pass-through securities ("RMBS") and other ABS. All of these entities were deemed VIEs because the equity within these entities is insufficient to sustain them. We determined we are not the primary beneficiary in the entities within these categories of investments. This determination was based primarily on the fact we do not own the class of security that controls the unilateral right to replace the special servicer or equivalent function.

We invest in cash collateralized debt obligations, collateralized bond obligations, collateralized loan obligations and other collateralized structures, which are VIEs due to insufficient equity to sustain the entities. We have determined we are not the primary beneficiary of these entities primarily because we do not control the economic performance of the entities and were not involved with the design of the entities or because we do not have a potentially significant variable interest in the entities for which we are the asset manager.

We have invested in various VIE trusts and similar entities as a debt holder. Most of these entities are classified as VIEs due to insufficient equity to sustain them. In addition, we have an entity classified as a VIE based on the combination of our significant economic interest and lack of voting rights. We have determined we are not the primary beneficiary primarily because we do not control the economic performance of the entities and were not involved with the design of the entities.

We have invested in partnerships and other funds, which are classified as VIEs. The entities are VIEs as equity holders lack the power to control the most significant activities of the entities because the equity holders do not have either the ability by a simple majority to exercise substantive kick-out rights or substantive participating rights. We have determined we are not the primary beneficiary because we do not have the power to direct the most significant activities of the entities.

As previously discussed, we sponsor and invest in certain investment funds that are VIEs. We determined we are not the primary beneficiary of the VIEs for which we are the asset manager but do not have a potentially significant variable interest in the funds.

Allowance for Credit Loss

We have a process in place to identify fixed maturity securities that could potentially require an allowance for credit loss. This process involves monitoring market events that could impact issuers’ credit ratings, business climate, management changes, litigation and government actions and other similar factors. This process also involves monitoring late payments, pricing levels, downgrades by rating agencies, key financial ratios, financial statements, revenue forecasts and cash flow projections as indicators of credit issues.

Each reporting period, all securities in an unrealized loss position are reviewed to determine whether a decline in value is due to credit. Relevant facts and circumstances considered include: (1) the extent the fair value is below cost; (2) the reasons for the decline in value; (3) the financial position and access to capital of the issuer, including the current and future impact of any specific events and (4) for structured securities, the adequacy of the expected cash flows. To the extent we determine an unrealized loss is due to credit, an allowance for credit loss is recognized through a reduction to net income.

We estimate the amount of the allowance for credit loss as the difference between amortized cost and the present value of the expected cash flows of the security. The present value is determined using the best estimate cash flows discounted at the effective interest rate implicit to the security at the date of purchase or the current yield to accrete an asset-backed or floating rate security. The methodology and assumptions for establishing the best estimate cash flows vary depending on the type of security. The ABS cash flow estimates are based on security specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity and prepayment speeds and structural support, including subordination and guarantees. The corporate security cash flow estimates are derived from scenario-based outcomes of expected corporate restructurings or liquidations using bond specific facts and circumstances including timing, security interests and loss severity. We do not measure a credit loss allowance on accrued interest receivable because we write off the accrued interest receivable balance to net investment income in a timely manner when we have concern regarding collectability.

Amounts on fixed maturities, available-for-sale deemed to be uncollectible are written off and removed from the allowance for credit loss. A write-off may also occur if we intend to sell a security or whether it is more likely than not we will be required to sell the security before the recovery of its amortized cost which, in some cases, may extend to maturity.

We did not write off any accrued interest to net investment income during the year ended December 31, 2020.

Other-Than-Temporary Impairments

Prior to the implementation of authoritative guidance in 2020, we had a process in place to identify fixed maturity securities that could potentially have an impairment that is other than temporary. This process involved monitoring market events that could impact issuers’ credit ratings, business climate, management changes, litigation and government actions and other similar factors. This process also involved monitoring late payments, pricing levels, downgrades by rating agencies, key financial ratios, financial statements, revenue forecasts and cash flow projections as indicators of credit issues.

Each reporting period, all securities were reviewed to determinewhether an other-than-temporary decline in value existed and whether losses should be recognized. We considered relevant facts and circumstances in evaluating whether a credit or interest rate related impairment of a security was other than temporary. Relevant facts and circumstances considered include: (1) the extent and length of time the fair value was below cost; (2) the reasons for the decline in value; (3) the financial position and access to capital of the issuer, including the current and future impact of any specific events; (4) for structured securities, the adequacy of the expected cash flows and (5) our intent to sell a security or whether it is more likely than not we will be required to sell the security before the recovery of its amortized cost which, in some cases, may extend to maturity. To the extent we determined a security was deemed to be other than temporarily impaired, an impairment loss was recognized.

The way in which impairment losses on fixed maturities were recognized in the financial statements was dependent on the facts and circumstances related to the specific security. If we intended to sell a security or it was more likely than not that we would be required to sell a security before the recovery of its amortized cost, we recognized an other-than-temporary impairment in net income for the difference between amortized cost and fair value. If we did not expect to recover the amortized cost basis, we did not plan to sell the security and if it was not more likely than not that we would be required to sell a security before the recovery of its amortized cost, the recognition of the other-than-temporary impairment was bifurcated. We recognized the credit loss portion in net income and the noncredit loss portion in OCI (“bifurcated OTTI”).

Prior to 2020, net realized capital gains (losses) included total other-than-temporary impairment losses, net of recoveries from the sale of previously impaired securities, as follows:

Net impairment losses on available-for-sale securities				(43.5)
Net realized capital losses		$	(112.2)

(1) Represents the net impact of (a) gains resulting from reclassification of noncredit impairment losses for fixed maturities

with bifurcated OTTI from net realized capital gains (losses) to OCI and (b) losses resulting from reclassification of

previously recognized noncredit impairment losses from OCI to net realized capital gains (losses) for fixed maturities

with bifurcated OTTI that had additional credit losses or fixed maturities that previously had bifurcated OTTI that have

now been sold or are intended to be sold.

We estimated the amount of the credit loss component of a fixed maturity security impairment as the difference between amortized cost and the present value of the expected cash flows of the security. The present value was determined using the best estimate cash flows discounted at the effective interest rate implicit to the security at the date of purchase or the current yield to accrete an asset-backed or floating rate security. The methodology and assumptions for establishing the best estimate cash flows varied depending on the type of security. The ABS cash flow estimates were based on security specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity and prepayment speeds and structural support, including subordination and guarantees. The corporate security cash flow estimates were derived from scenario-based outcomes of expected corporate restructurings or liquidations using bond specific facts and circumstances including timing, security interests and loss severity.

The following table provides a rollforward of accumulated credit losses for fixed maturities with bifurcated credit losses prior to the implementation of new accounting guidance in 2020. The purpose of the table is to provide detail of (1) additions to the bifurcated credit loss amounts recognized in net realized capital gains (losses) during the period and (2) decrements for previously recognized bifurcated credit losses where the loss is no longer bifurcated and/or there has been a positive change in expected cash flows or accretion of the bifurcated credit loss amount.

Of the available-for-sale fixed maturities within our consolidated portfolio in a gross unrealized loss position, 91% were investment grade (rated AAA through BBB-) with an average price of 98 (carrying value/amortized cost) as of December 31, 2021. Gross unrealized losses in our fixed maturities portfolio increased during the year ended December 31, 2021, primarily due to an increase in interest rates, partially offset by tightening of credit spreads.

For those securities that had been in a continuous unrealized loss position for less than twelve months, our consolidated portfolio held 1,805 securities reflecting an average price of 99 as of December 31, 2021. Of this portfolio, 90% was investment grade (rated AAA through BBB-) as of December 31, 2021, with associated unrealized losses of $138.9 million. The unrealized losses on these securities can primarily be attributed to changes in market interest rates and changes in credit spreads since the securities were acquired.

For those securities that had been in a continuous unrealized loss position greater than or equal to twelve months, our consolidated portfolio held 459 securities reflecting an average price of 95 and an average credit rating of A+ as of December 31, 2021. Corporate securities with unrealized losses had an average price of 95 and an average credit rating of BBB+. U.S. government and agency securities with unrealized losses had an average price of 93 and an average credit rating of AAA. Commercial mortgage-backed securities with unrealized losses had an average price of 95 and an average credit rating of AAA. Collateralized debt obligation securities with unrealized losses had an average price of 98 and an average credit rating of AA+. The unrealized losses on these securities can primarily be attributed to changes in market interest rates and changes in credit spreads since the securities were acquired.

Because we expected to recover our amortized cost, we did not record an allowance for credit loss on these securities as of December 31, 2021. Because it was not our intent to sell the fixed maturity available-for-sale securities with unrealized losses and it was not more likely than not that we would be required to sell these securities before recovery of the amortized cost, which may be at maturity, we did not write down these investments to fair value.

Financing Receivables

Mortgage Loans

Mortgage loans consist of commercial and residential mortgage loans. Our commercial mortgage loan portfolio consists primarily of non-recourse, fixed rate mortgages on stabilized properties. Our residential mortgage loan portfolio is composed of first lien and home equity mortgages.

Commercial and residential mortgage loans are generally reported at cost adjusted for amortization of premiums and accrual of discounts, computed using the interest method and net of valuation allowances. Amortized cost excludes accrued interest receivable. Interest income is accrued on the principal amount of the loan based on the loan's contractual interest rate. Interest income, as well as prepayment of fees and the amortization of the related premium or discount, is reported in net investment income on the consolidated statements of operations. Accrued interest receivable is reported in accrued investment income on the consolidated statements of financial position. Any changes in the loan valuation allowances are reported in net realized capital gains (losses) on the consolidated statements of operations. Further details relating to our valuation allowance are included under the caption “Financing Receivables Valuation Allowance.”

Reinsurance Recoverables

Our reinsurance recoverables include amounts due from reinsurers for paid or unpaid claims, claims incurred but not reported or policy benefits. We cede life, disability, medical and long-term care insurance to other insurance companies through reinsurance. Reinsurance recoverables are reported with premiums due and other receivables in the consolidated statements of financial position.

Financing Receivables Credit Monitoring

Commercial Mortgage Loan Credit Risk Profile Based on Internal Rating

We actively monitor and manage our commercial mortgage loan portfolio. All commercial mortgage loans are analyzed regularly and substantially all are internally rated, based on a proprietary risk rating cash flow model, in order to monitor the financial quality of these assets. The model stresses expected cash flows at various levels and at different points in time depending on the durability of the income stream, which includes our assessment of factors such as location (macro and micro markets), tenant quality and lease expirations. Our internal rating analysis presents expected losses in terms of an S&P Global (“S&P”) bond equivalent rating for commercial mortgage loans. As the credit risk for commercial mortgage loans increases, we adjust our internal ratings downward with loans in the category “B+ and below” having the highest risk for credit loss. Internal ratings on commercial mortgage loans are updated at least annually and potentially more often for certain loans with material changes in collateral value or occupancy and for loans on an internal “watch list”.

Commercial mortgage loans that require more frequent and detailed attention are identified and placed on an internal “watch list”. Among the criteria that may indicate a potential problem are significant negative changes in ratios of loan to value or contract rents to debt service, major tenant vacancies or bankruptcies, borrower sponsorship problems, late payments, delinquent taxes and loan relief/restructuring requests.

Residential Mortgage Loan Credit Risk Profile Based on Performance Status

Our residential mortgage loan portfolio is monitored based on performance of the loans. Monitoring on a residential mortgage loan increases when the loan is delinquent or earlier if there is an indication of potential impairment. We define non-performing residential mortgage loans as loans 90 days or greater delinquent or on non-accrual status.

Non-Accrual Financing Receivables

Financing receivables are placed on non-accrual status if we have concern regarding the collectability of future payments or if a financing receivable has matured without being paid off or extended. Factors considered may include conversations with the borrower, loss of major tenant, bankruptcy of borrower or major tenant, decreased property cash flow for commercial mortgage loans or number of days past due and other circumstances for residential mortgage loans. Based on an assessment as to the collectability of the principal, a determination is made to apply any payments received either against the principal, against the valuation allowance or according to the contractual terms. When a financing receivable is placed on non-accrual status, the accrued unpaid interest receivable is reversed against interest income. Accrual of interest resumes after factors resulting in doubts about collectability have improved.

The amortized cost of financing receivables on non-accrual status was as follows:

	December 31, 2021
							Amortized cost
	Beginning			Ending			of nonaccrual
	amortized cost			amortized cost			assets without

(1)As of both December 31, 2021 and 2020, no reinsurance recoverables were considered past due.

We did not have any mortgage loans that were 90 days or more past due and still accruing interest as of December 31, 2021 and 2020.

Financing Receivables Valuation Allowance

We establish a valuation allowance to provide for the risk of credit losses inherent in our financing receivables. The valuation allowance is maintained at a level believed adequate by management to absorb estimated expected credit losses. The valuation allowance is based on amortized cost excluding accrued interest receivable and includes reserves for pools of financing receivables with similar risk characteristics. We do not measure a credit loss allowance on accrued interest receivable because we write off the uncollectible accrued interest receivable balance to net investment income in a timely manner, generally within 90 days. During 2021 and 2020, we did not write off any commercial mortgage loan accrued interest or residential mortgage loan accrued interest.

For commercial and residential mortgage loans, management's periodic evaluation and assessment of the valuation allowance adequacy is based on known and inherent risks in the portfolio, adverse situations that may affect a borrower's ability to repay, the estimated value of the underlying collateral, composition of the portfolio, portfolio delinquency information, underwriting standards, peer group information, current and forecasted economic conditions, loss experience and other relevant factors. For reinsurance recoverables, management’s periodic evaluation and assessment of the valuation allowance adequacy is based on known and inherent risks, adverse situations that may affect a reinsurer’s ability to repay, current and forecasted economic conditions, industry loss experience and other relevant factors.

Our commercial mortgage loans are pooled by risk rating level with an estimated loss ratio applied against each risk rating level. The loss ratio is generally based upon historical loss experience for each risk rating level as adjusted for certain current and forecasted environmental factors management believes to be relevant. Environmental factors are forecasted for two years or less with immediate reversion to historical experience. A commercial mortgage loan is evaluated individually if it does not continue to share similar risk characteristics of a pool. We analyze the need for an individual evaluation for any commercial mortgage loan that is delinquent for 60 days or more, in process of foreclosure, restructured, on the internal “watch list” or that currently is evaluated individually.

We estimate expected credit losses for certain commercial mortgage loan commitments where we have a contractual obligation to extend credit. The expected credit losses are estimated based on the commercial mortgage loan valuation allowance process described previously, adjusted for probability of funding. The estimated expected credit losses for commercial mortgage loan commitments are reported in other liabilities on the consolidated statements of financial position. The change in the credit loss liability for commitments is included in net realized capital gains (losses) on the consolidated statements of operations. Once funded, expected credit losses for commercial mortgage loans are included within the commercial mortgage loan valuation allowance described previously.

We evaluate residential mortgage loans based on aggregated risk factors and historical loss experience by pool type. We adjust these quantitative factors for qualitative factors of present and forecasted conditions. Qualitative factors include items such as economic and business conditions, changes in the portfolio, value of underlying collateral and concentrations. A residential mortgage loan is evaluated individually if it does not continue to share similar risk characteristics of a pool. We analyze the need for an individual evaluation for any residential mortgage loan that is delinquent for 60 days or more, in process of foreclosure, restructured, on the internal “watch list” or that currently is evaluated individually.

As discussed previously, commercial and residential mortgage loans are evaluated individually if the asset does not continue to share similar risk characteristics of a pool. When we determine a commercial or residential mortgage loan is probable of foreclosure, a valuation allowance is established equal to the difference between the carrying amount of the mortgage loan and the estimated value of the collateral reduced by the cost to sell. For certain commercial mortgage loans where repayment is expected to be provided substantially through the operation or sale of the collateral and the borrower is experiencing financial difficulty, we elect to establish a valuation allowance equal to the difference between the carrying amount of the mortgage loan and the estimated value of the real estate collateral, which may be reduced by the cost to sell. Estimated value may also be based on either the present value of the expected future cash flows discounted at the asset's effective interest rate or the asset's observable market price. Subsequent changes in the estimated value are reflected in the valuation allowance. Amounts on financing receivables deemed to be uncollectible are charged off and removed from the valuation allowance. The change in the valuation allowance for loans is included in net realized capital gains (losses) on the consolidated statements of operations.

Our reinsurance recoverables are pooled by reinsurer risk rating with an estimated loss ratio applied against each risk rating level. The loss ratio is generally based upon industry historical loss experience and expected recovery timing as adjusted for certain current and forecasted environmental factors management believes to be relevant. Environmental factors are forecasted for five years or less with immediate reversion to industry historical experience. A reinsurance recoverable is evaluated individually if it does not continue to share similar risk characteristics of a pool. We analyze the need for an individual evaluation for any reinsurance recoverable based on past due payments and changes in reinsurer risk ratings. The change in the valuation allowance for reinsurance recoverables is included in benefits, claims and settlement expenses on the consolidated statements of operations.

(1)During the year ended December 31, 2021, certain valuation allowances for residential mortgage loans were released. This release was a result of further adjustments to our current and forecasted environmental factors management believed to be relevant as global economic activity improved from previously adverse impacts due to COVID-19.

(2)During the year ended December 31, 2020, COVID-19 adversely impacted global economic activity and contributed to significant volatility in financial markets. As a result, certain current and forecasted environmental factors management believed to be relevant were adjusted, resulting in an increase in the valuation allowance for commercial and residential mortgage loans.

(3)Upon adoption of authoritative guidance effective January 1, 2020, we updated accounting policies and methodology, adjusted the commercial and residential mortgage loan valuation allowance and established a valuation allowance for reinsurance recoverables. See Note 1, Nature of Operations and Significant Accounting Policies under the caption, “Recent Accounting Pronouncements” for further details.

(4)Prior to the implementation of authoritative guidance in 2020, only commercial and residential mortgage loans were included in the allowance rollforward and the allowance was based on either individual or collective evaluation.

Mortgage Loan Modifications

    We assess COVID-19 related loan modifications to determine if they are in scope of the CARES Act TDR relief and the Interagency Statement guidance, which was effective the second quarter of 2020. See Note 1, Nature of Operations and Significant Accounting Policies, under the caption “Investments” for further details. COVID-19 related loan modifications typically include delayed principal and interest payments. Based on the terms of the delayed principal and interest payments, past due status generally will not advance, and loans generally will not be placed on non-accrual status during the delay. We did not have a significant amount of COVID-19 related loan modifications that were in scope of the CARES Act TDR relief or the Interagency Statement guidance for the years ended December 31, 2021 and 2020.

We assess loan modifications outside the scope of the CARES Act TDR relief or Interagency Statement guidance on a case-by-case basis to evaluate whether a TDR has occurred. When we have commercial mortgage loan TDRs, they are modified to delay or reduce principal payments and to reduce or delay interest payments. The commercial mortgage loan modifications result in delayed cash receipts, a decrease in interest income and loan rates that are considered below market. When we have residential mortgage loan TDRs, they include modifications of interest-only payment periods, delays in principal balloon payments and interest rate reductions. Residential mortgage loan modifications result in delayed or decreased cash receipts and a decrease in interest income.

When we have commercial mortgage loan TDRs, they are reserved for in the mortgage loan valuation allowance at the estimated fair value of the underlying collateral reduced by the cost to sell.

When we have residential mortgage loan TDRs, they are specifically reserved for in the mortgage loan valuation allowance if losses result from the modification. Residential mortgage loans that have defaulted or have been discharged through bankruptcy are reduced to the expected collectible amount.

We did not have any significant loans that were modified and met the criteria of a TDR for the years ended December 31, 2021, 2020 and 2019.

6. 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.

Types of Derivative Instruments

Interest Rate Contracts

Interest rate risk is the risk 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/or 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 any party. Cash is paid or received based on the terms of the swap. We use interest rate swaps primarily to more closely match the interest rate characteristics of assets and liabilities and to mitigate the risks 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.

Interest rate options, including interest rate caps and interest rate floors, which can be combined to form interest rate collars, are contracts that entitle the purchaser to pay or receive the amounts, if any, by which a specified market rate exceeds a cap strike interest rate, or falls below a floor strike interest rate, respectively, at specified dates. We use interest rate options to manage prepayment risks in our assets and minimum guaranteed interest rates and lapse risks in our liabilities.

A swaption is an option to enter into an interest rate swap at a future date. We have purchased swaptions to hedge interest rate exposure for certain assets and liabilities. 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 daily basis in an amount equal to the difference in the daily market values of those contracts. We enter into exchange-traded futures with regulated futures commissions merchants who are members of a trading exchange. We use exchange-traded futures to hedge against changes in value of the GMWB liability.

Interest rate forwards, including to be announced (“TBA”) forwards and treasury forwards, are contracts to take delivery of a fixed income security at a specified price at a future date. TBA forwards deliver government guaranteed mortgage-backed securities and treasury forwards deliver U.S. Treasury bonds. At inception of these forward contracts we do not intend to take physical delivery. We have used TBA forwards to gain exposure to the investment risk and return of agency mortgage-backed security pools in order to reduce asset and liability duration mismatch. Treasury forwards are used to hedge against changes in the value of the GMWB liability.

Foreign Exchange Contracts

Foreign currency risk is the risk we will incur economic losses due to adverse fluctuations in foreign currency exchange rates. This risk arises from foreign currency-denominated funding agreements issued to nonqualified institutional investors in the international market and foreign currency-denominated fixed maturities we invest in. We use various derivatives to manage our exposure to fluctuations in foreign currency exchange rates.

Currency swaps are contracts in which we agree with other parties to exchange, at specified intervals, a series of principal and interest payments in one currency for that of another currency. Generally, the principal amount of each currency is exchanged at the beginning and termination of the currency swap by each party. The interest payments are primarily fixed-to-fixed rate; however, they may also be fixed-to-floating rate or floating-to-fixed rate. These transactions are entered into pursuant to master agreements that provide for a single net payment to be made by one counterparty for payments made in the same currency at each due date. We use currency swaps to reduce market risks from changes in currency exchange rates with respect to investments or liabilities denominated in foreign currencies that we either hold or intend to acquire or sell.

B-42

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2021

Currency forwards are contracts in which we agree with other parties to deliver or receive a specified amount of an identified currency at a specified future date. Typically, the price is agreed upon at the time of the contract and payment for such a contract is made at the specified future date. We use currency forwards to hedge certain foreign-denominated real estate funds.

Equity Contracts

Equity risk is the risk that we will incur economic losses due to adverse fluctuations in common stock prices. We use various derivatives to manage our exposure to equity risk, which arises from products in which the return or interest we credit is tied to an external equity index as well as products subject to minimum contractual guarantees.

We purchase equity call spreads (“option collars”) to hedge the equity participation rates promised to contractholders in conjunction with our fixed deferred annuity and universal life products that credit interest based on changes in an external equity index. We use exchange-traded futures and equity put options to hedge against changes in the value of the GMWB liability related to the GMWB rider on our variable annuity product. The premium associated with certain options is paid quarterly over the life of the option contract.

We use exchange-traded futures to hedge against changes in value of the GMWB liability.

Credit Contracts

Credit risk relates to the uncertainty associated with the continued ability of a given obligor to make timely payments of principal and interest. We use credit default swaps to enhance the return on our investment portfolio by providing comparable exposure to fixed income securities that might not be available in the primary market. They are also used to hedge credit exposures in our investment portfolio. Credit derivatives are used to sell or buy credit protection on an identified name or names on an unfunded or synthetic basis in return for receiving or paying a quarterly premium. The premium generally corresponds to a referenced name's credit spread at the time the agreement is executed. In cases where we sell protection, we also buy a quality cash bond to match against the credit default swap, thereby entering into a synthetic transaction replicating a cash security. When selling protection, if there is an event of default by the referenced name, as defined by the agreement, we are obligated to pay the counterparty the referenced amount of the contract and receive in return the referenced security in a principal amount equal to the notional value of the credit default swap.

Other Contracts

Embedded Derivatives. We purchase or issue certain financial instruments or products that contain a derivative instrument that is embedded in the financial instrument or product. When it is determined that the embedded derivative possesses economic characteristics that are not clearly or closely related to the economic characteristics of the host contract and a separate instrument with the same terms would qualify as a derivative instrument, the embedded derivative is bifurcated from the host instrument for measurement purposes. The embedded derivative, which is reported with the host instrument in the consolidated statements of financial position, is carried at fair value.

We offer group annuity contracts that have guaranteed separate accounts as an investment option.

We have fixed deferred annuities and universal life products that credit interest based on changes in an external equity index. We also have certain variable annuity products with a GMWB rider, which allows the customer to make withdrawals of a specified annual amount, either for a fixed number of years or for the lifetime of the customer, even if the account value is fully exhausted. Declines in the equity markets may increase our exposure to benefits under contracts with the GMWB. We economically hedge the exposure in these contracts, as previously explained.

Exposure

    Our risk of loss is typically limited to the fair value of our derivative instruments and not to the notional or contractual amounts of these derivatives. We are also exposed to credit losses in the event of nonperformance of the counterparties. Our current credit exposure is limited to the value of derivatives that have become favorable to us. This credit risk is minimized by purchasing such agreements from financial institutions with high credit ratings and by establishing and monitoring exposure limits. We also utilize various credit enhancements, including collateral and credit triggers to reduce the credit exposure to our derivative instruments.

    Derivatives may be exchange-traded or they may be privately negotiated contracts, which are usually referred to as over-the-counter (“OTC”) derivatives. Certain of our OTC derivatives are cleared and settled through central clearing counterparties (“OTC cleared”), while others are bilateral contracts between two counterparties (“bilateral OTC”).Our derivative transactions are generally documented under International Swaps and Derivatives Association, Inc. (“ISDA”) Master Agreements. Management believes that such agreements provide for legally enforceable set-off and close-out netting of exposures to specific counterparties. Under such agreements, in connection with an early termination of a transaction, we are permitted to set off our receivable from a counterparty against our payables to the same counterparty arising out of all included transactions. For reporting purposes, we do not offset fair value amounts of bilateral OTC derivatives for the right to reclaim cash collateral or the obligation to return cash collateral against fair value amounts recognized for derivative instruments executed with the same counterparties under master netting agreements. OTC cleared derivatives have variation margin that is legally characterized as settlement of the derivative exposure, which reduces their fair value in the consolidated statements of financial position.

We posted $164.8 million and $122.6 million in cash and securities under collateral arrangements as of December 31, 2021 and December 31, 2020, respectively, to satisfy collateral and initial margin requirements associated with our derivative credit support agreements and FCM agreements.

Certain of our derivative instruments contain provisions that require us to maintain an investment grade rating from each of the major credit rating agencies on our debt. If the ratings on our debt were to fall below investment grade, it would be in violation of these provisions and the counterparties to the derivative instruments could request immediate payment or demand immediate and ongoing full overnight collateralization on derivative instruments in net liability positions. The aggregate fair value, inclusive of accrued interest, of all derivative instruments with credit-risk-related contingent features that were in a liability position without regard to netting under derivative credit support annex agreements as of December 31, 2021 and December 31, 2020, was $145.7 million and $165.7 million, respectively. Cleared derivatives have contingent features that require us to post excess margin as required by the FCM. The terms surrounding excess margin vary by FCM agreement. With respect to derivatives containing collateral provisions, we posted collateral and initial margin of $164.8 million and $122.6 million as of December 31, 2021 and December 31, 2020, respectively, in the normal course of business, which reflects netting under derivative agreements. If the credit-risk-related contingent features underlying these agreements were triggered on December 31, 2021, we would be required to post an additional $48.4 million of collateral to our counterparties.

As of December 31, 2021 and December 31, 2020, we had received $204.4 million and $220.5 million, respectively, of cash collateral associated with our derivative credit support annex agreements and FCM agreements, for which we recorded a corresponding liability reflecting our obligation to return the collateral.

Credit Derivatives Sold

When we sell credit protection, we are exposed to the underlying credit risk similar to purchasing a fixed maturity security instrument. Our credit derivative contracts sold reference a single name or reference security (referred to as “single name credit default swaps”). These instruments are either referenced in an OTC credit derivative transaction or embedded within an investment structure that has been fully consolidated into our financial statements.

These credit derivative transactions are subject to events of default defined within the terms of the contract, which normally consist of bankruptcy, failure to pay, or modified restructuring of the reference entity and/or issue. If a default event occurs for a reference name or security, we are obligated to pay the counterparty an amount equal to the notional amount of the credit derivative transaction. As a result, our maximum future payment is equal to the notional amount of the credit derivative. In certain cases, we also may have purchased credit protection with identical underlyings to certain of our sold protection transactions. As of December 31, 2021 and December 31, 2020, we did not purchase credit protection relating to our sold protection transactions. In certain circumstances, our potential loss could also be reduced by any amount recovered in the default proceedings of the underlying credit name.

Fair Value and Cash Flow Hedges

Fair Value Hedges

    We use fixed-to-floating rate interest rate swaps to more closely align the interest rate characteristics of certain assets and have used them to align the interest rate characteristics of certain liabilities. In general, these swaps are used in asset and liability management to modify duration, which is a measure of sensitivity to interest rate changes.

The net interest effect of interest rate swap transactions for derivatives in fair value hedges is recorded as an adjustment to income or expense of the underlying hedged item in our consolidated statements of operations.

Cash Flow Hedges

    We utilized floating-to-fixed rate interest rate swaps to eliminate the variability in cash flows of recognized financial assets and liabilities and forecasted transactions.

    We enter into currency exchange swap agreements to convert both principal and interest payments of certain foreign denominated assets and liabilities into U.S. dollar denominated fixed-rate instruments to eliminate the exposure to future currency volatility on those items.

The net interest effect of interest rate swap and currency swap transactions for derivatives in cash flow hedges is recorded as an adjustment to income or expense of the underlying hedged item in our consolidated statements of operations.

The following table shows the effect of derivatives in cash flow hedging relationships on the consolidated statements of financial position.

		Amount of gain (loss) recognized in AOCI on derivatives
Derivatives in cash flow		for the year ended December 31,

Derivatives Not Designated as Hedging Instruments

    Our use of futures, certain swaptions and swaps, option collars, options and forwards are effective from an economic standpoint, but they have not been designated as hedges for financial reporting purposes. As such, periodic changes in the market value of these instruments, which includes mark-to-market gains and losses as well as periodic and final settlements, primarily flow directly into net realized capital gains (losses) on the consolidated statements of operations.

The following table shows the effect of derivatives not designated as hedging instruments, including fair value changes of embedded derivatives that have been bifurcated from the host contract, on the consolidated statements of operations.

7. Closed Block

In connection with the 1998 MIHC formation, we formed a Closed Block to provide reasonable assurance to policyholders included therein that, after the formation of the MIHC, assets would be available to maintain dividends in aggregate in accordance with the 1997 policy dividend scales, if the experience underlying such scales continued. Our assets were allocated to the Closed Block in an amount that produces cash flows which, together with anticipated revenue from policies and contracts included in the Closed Block, were expected to be sufficient to support the Closed Block policies. This includes, but is not limited to, provisions for payment of claims, certain expenses, charges and taxes, and to provide for continuation of policy and contract dividends in aggregate in accordance with the 1997 dividend scales, if the experience underlying such scales continues, and to allow for appropriate adjustments in such scales, if such experience changes. Due to adjustable life policies being included in the Closed Block, the Closed Block is charged with amounts necessary to properly fund for certain adjustments, such as face amount and premium increases, that are made to these policies after the Closed Block inception date. These amounts are referred to as Funding Adjustment Charges and are treated as capital transfers from the Closed Block.

Assets allocated to the Closed Block inure solely to the benefit of the holders of policies included in the Closed Block. Closed Block assets and liabilities are carried on the same basis as other similar assets and liabilities. We will continue to pay guaranteed benefits under all policies, including the policies within the Closed Block, in accordance with their terms. If the assets allocated to the Closed Block, the investment cash flows from those assets and the revenues from the policies included in the Closed Block, including investment income thereon, prove to be insufficient to pay the benefits guaranteed under the policies included in the Closed Block, we will be required to make such payments from our general funds. No additional policies were added to the Closed Block, nor was the Closed Block affected in any other way, as a result of the demutualization.

A policyholder dividend obligation (“PDO”) is required to be established for higher than expected earnings in the Closed Block that will need to be paid as dividends unless future performance of the Closed Block is less favorable than originally expected. A model of the Closed Block was established to produce the pattern of expected earnings, assets and liabilities in the Closed Block. These projections are utilized to determine ratios that will allow us to compare actual cumulative earnings to expected cumulative earnings and determine the amount of the PDO. As of December 31, 2021 and 2020, the PDO was $210.7 million and $298.2 million, respectively.

Contractholder Funds

    Major components of contractholder funds in the consolidated statements of financial position were as follows:

		December 31,
		2021			2020
		(in millions)
Liabilities for investment contracts:
	Liabilities for individual annuities	$	10,652.3		$	12,864.1
	GICs			12,206.0			11,858.0
	Funding agreements			11,685.5			9,407.3

Total liabilities for investment contracts				35,540.9			35,176.7
Universal life and other reserves				7,416.4			7,296.6
Total contractholder funds		$	42,957.3		$	42,473.3

    Our GICs and funding agreements contain provisions limiting or prohibiting early surrenders, which typically include penalties for early surrenders, minimum notice requirements or, in the case of funding agreements with survivor options, minimum pre-death holding periods and specific maximum amounts.

Funding agreements include those issued directly to nonqualified institutional investors and those issued to the

FHLB Des Moines under their membership funding programs. As of December 31, 2021 and 2020, $4,252.4 million and $4,252.5 million, respectively, of liabilities were outstanding with respect to issuances under the program with FHLB Des Moines. In addition, we have five separate programs where the funding agreements have been issued directly or indirectly to unconsolidated special purpose entities. Claims for principal and interest under funding agreements are afforded equal priority to claims of life insurance and annuity policyholders under insolvency provisions of Iowa Insurance Laws.

We were authorized to issue up to $4.0 billion of funding agreements under a program established in 1998 to support the prospective issuance of medium term notes by an unaffiliated entity in non-U.S. markets. As of both December 31, 2021 and 2020, $75.0 million of liabilities were outstanding with respect to the issuance outstanding under this program. We were also authorized to issue up to Euro 4.0 billion (approximately USD$5.3 billion) of funding agreements under a program established in 2006 to support the prospective issuance of medium term notes by an unaffiliated entity in non-U.S. markets. The unaffiliated entity is an unconsolidated special purpose entity. As of December 31, 2021 and 2020, $0.0 million and $122.4 million, respectively, of liabilities were outstanding with respect to issuances outstanding under this program. We do not anticipate any new issuance activity under either of these programs due to the existence of the program established in 2011 described below.

In addition, we were authorized to issue up to $7.0 billion of funding agreements under a program established in 2001 to support the prospective issuance of medium term notes by an unaffiliated entity in both domestic and international markets. The unaffiliated entity is an unconsolidated special purpose entity. As of both December 31, 2021 and 2020, $201.8 million of liabilities were being held with respect to issuances outstanding under this program. We do not anticipate any new issuance activity under this program, given our December 2005 termination of the dealership agreement for this program and the availability of the program established in 2011 described below.

We were authorized to issue up to $5.0 billion of funding agreements under a program that was originally established in 2011 to support the prospective issuance of medium term notes by an unaffiliated entity in both domestic and international markets. The unaffiliated entity is an unconsolidated special purpose entity. In June 2015, this program was amended to authorize issuance of up to an additional $4.0 billion in recognition of the use of nearly all $5.0 billion of existing issuance authorization. In November 2017, this program was amended to authorize issuance of up to an additional $4.0 billion. In February 2021, this program was amended to authorize issuance of up to an additional $4.0 billion. As of December 31, 2021 and 2020, $7,156.3 million and $4,755.8 million, respectively, of liabilities were being held with respect to issuances outstanding under this program. Our payment obligations on each funding agreement issued under this program are guaranteed by PFG. The program established in 2011 is not registered with the United States Securities and Exchange Commission (“SEC”).

Liability for Unpaid Claims

The liability for unpaid claims is reported in future policy benefits and claims within our consolidated statements of financial position. Activity associated with unpaid claims was as follows:

		For the year ended December 31,
		2021			2020			2019
		(in millions)
Balance at beginning of year		$	2,534.9		$	2,365.5		$	2,252.7
Less: reinsurance recoverable				436.9			403.8			404.3
Net balance at beginning of year				2,098.0			1,961.7			1,848.4

	Current year			1,572.5			1,376.8			1,361.3
	Prior years			7.2			26.6			0.8
Total incurred				1,579.7			1,403.4			1,362.1
Payments:
	Current year			1,025.0			863.8			869.4
	Prior years			435.4			403.3			379.4
Total payments				1,460.4			1,267.1			1,248.8
Net balance at end of year				2,217.3			2,098.0			1,961.7
Plus: reinsurance recoverable				442.1			436.9			403.8
Balance at end of year		$	2,659.4		$	2,534.9		$	2,365.5
Amounts not included in the rollforward above:
	Claim adjustment expense liabilities	$	59.5		$	57.8		$	57.9

    Incurred liability adjustments relating to prior years, which affected current operations during 2021, 2020 and 2019, resulted in part from developed claims for prior years being different than were anticipated when the liabilities for unpaid claims were originally estimated. These trends have been considered in establishing the current year liability for unpaid claims.

Short-Duration Contracts

Claims Development

    The following tables present undiscounted information about claims development by incurral year, including separate information about incurred claims and paid claims net of reinsurance for the periods indicated. The tables also include information on incurred but not reported claims and the cumulative number of reported claims.

The tables present information for the number of years for which claims incurred typically remain outstanding, but do not exceed ten years. The data is disaggregated into groupings of claims with similar characteristics, such as duration of the claim payment period and average claim amount, and with consideration to the overall size of the groupings. Outstanding liabilities equal total net incurred claims less total net paid claims plus outstanding liabilities for net unpaid claims of prior years.

(1) Our 2021 effective income tax rate would not be impacted if unrecognized tax benefits were recognized. We recognize interest and penalties related to uncertain tax positions in operating expenses within the consolidated statements of operations.

As of December 31, 2021, 2020 and 2019, we had recognized $1.2 million, $1.1 million and $0.8 million of accumulated pre-tax interest and penalties related to unrecognized tax benefits, respectively. We do not believe there is a reasonable possibility the total amount of the unrecognized tax benefits will significantly increase or decrease in the next twelve months considering recent settlements and the status of current and pending Internal Revenue Service (“IRS”) examinations.

Net Deferred Income Taxes

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Our significant components of net deferred income taxes were as follows:

Our net deferred income taxes by jurisdiction were as follows:

		December 31,
		2021			2020
		(in millions)
Deferred income tax liabilities:
	U.S. federal	$	(2,245.1)		$	(2,285.0)
	State			(28.4)			(33.4)
Total net deferred income tax liabilities		$	(2,273.5)		$	(2,318.4)

In management’s judgment, total deferred income tax assets are more likely than not to be realized. Included in the deferred income tax asset are tax carryforwards available to offset future taxable income or income taxes.As of December 31, 2021 and 2020, we had tax credit carryforwards for U.S. federal income tax purposes of $0.0 million and $4.3 million, respectively. Foreign and general business tax credit carryovers were generated during and since the period we utilized net operating losses, primarily attributable to our captive reinsurance companies that joined PFG’s consolidated U.S. federal income tax return beginning in 2012 and 2013. Alternative minimum tax credit carryforwards became refundable for the 2018 tax year under the 2020 CARES Act and were fully recovered. In addition, the foreign tax and general business credit carryforwards were fully utilized in 2020 and 2021, respectively.

As of both December 31, 2021 and 2020, state net operating loss carryforwards were $0.3 million and will expire between 2032 and 2040. As of December 31, 2021, all accumulated state net operating loss carryforwards are anticipated to be utilized before expiration; therefore, no valuation allowance has been provided for the related deferred income tax assets.

Other Tax Information

Income tax returns are filed in U.S. federal jurisdiction as well as various states where we and one or more of our subsidiaries conduct business. Although determined by jurisdiction, with few exceptions our tax uncertainties relate primarily to the U.S. federal jurisdiction. The IRS has completed examination of PFG’s consolidated U.S. federal income tax returns for years prior to 2015. IRS claims for refund for tax years 2004 through 2008, following settlement of a partnership matter with the Department of Justice in March 2019, were finalized in 2020 and have been received in full as of December 31, 2021. IRS claims for refund filed for tax years 2006 through 2008 were received in September 2020. In 2019, an IRS 30-day letter on examination of tax years 2009 through 2012 was received, the proposed adjustments found acceptable, and associated tax settlements subsequently occurred in 2020 prior to expiration of the extended statute of limitations. As of December 31, 2021 and 2020, we had $16.8 million and $58.4 million, respectively, of current income tax receivables associated with outstanding audit issues.

The IRS is currently auditing PFG’s consolidated U.S. federal income tax returns for tax years 2015-2018. The U.S. federal statute of limitations expired for years prior to 2009, except for pending audit issues. The extended statute expired on June 30, 2021, for 2009 through 2012 although effectively settled, and the original statute has expired for both 2013 and 2014. Tax years 2015 and forward remain open through statute extensions or the normal statute of limitations. The ultimate settlement of earlier tax years can be adjusted into subsequent tax years regardless of statute status. We do not expect the results of these audits, subsequent related adjustments or developments in other tax areas for all open tax years 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.

We believe we have adequate defenses against, or sufficient provisions for, contested issues, but final resolution could take several years depending on whether legal remedies are pursued. Consequently, we do not believe issues that might arise in tax years subsequent to 2014 will have a material impact on our net income.

12. Employee and Agent Benefits

PFG provides a U.S. qualified defined benefit pension plan, covering U.S. employees that meet certain eligibility requirements and certain agents contracted on or before December 31, 2018. A final average pay benefit formula has been in place for plan participants employed prior to January 1, 2002. For agents, this formula ended on December 31, 2018, and for employees the formula will end on December 31, 2022. The final average pay benefit is based on the years of service and generally the employee's or agent's average annual compensation during the last five years prior to the earliest of termination, retirement or the formula end date. A cash balance benefit was added on January 1, 2002. A participant's cash balance account is credited with an amount based on the participant’s salary, age and service. These credits accrue with interest. For plan participants hired on and after January 1, 2002, only the cash balance benefit applies. For pre-2002 participants, the pension benefit earned prior to the final average pay formula end date is the greater of the final average pay benefit or the cash balance benefit earned before the end date. They will also earn a new cash balance benefit for service after the formula end date. We reflect pension expense through our expense allocation agreement with PFG.

In addition, PFG sponsors non-qualified defined benefit plans subject to Section 409A of the Internal Revenue Code. This plan is for certain highly compensated employees and agents to replace the benefit that cannot be provided by the qualified defined benefit pension plan due to IRS limits. These nonqualified plans generally parallel the qualified plan but offer different payment options. No agent will become a new participant in the nonqualified plan after December 31, 2018.

We provide certain health care, life insurance and long-term care benefits for retired employees, their beneficiaries and covered dependents ("other postretirement benefits"). While virtually all U.S. employees continue to have access to the postretirement health care and life insurance benefits, only those U.S. employees that were hired prior to January 1, 2002, and retired prior to January 1, 2011, (post-65 medical) or January 1, 2020, (life insurance and pre-65 medical) were eligible to receive subsidized benefits. All others pay the full cost of coverage. The long-term care plan was subsidized only for those who retired prior to January 1, 2000, and is no longer accessible. The subsidy level for all benefits varies by plan, age, service and retirement date. Our policy is to fund the cost of providing retiree benefits in the years the employees are providing service, taking into account the funded status of the trust. PFG is the sponsor of the post-65 retiree medical plan for both employees and individual field agents.

Other Postretirement Plan Changes and Plan Gains/Losses

For the year ended December 31, 2021, the other postretirement benefit plans had an actuarial gain primarily due to an increase in the discount rate and actual, along with projected, medical claim costs being lower than previously expected. For the year ended December 31, 2020, the other postretirement benefit plans had an actuarial loss primarily due to a decrease in the discount rate and a higher than expected number of retirees electing medical coverage with the elimination of subsidized benefits.

Effective January 1, 2021, the Long-Term Care Assistance Plan merged with the Principal Welfare Plan for Medicare Eligible Retirees and PFG became the plan sponsor. The result of the plan merger was a liability of $2.9 million moving to PFG. In addition, the net unrecognized actuarial loss of $2.0 million and the prior period service cost of $0.7 million from the long-term care plan moved to PFG with the plan merger.

Notes to Consolidated Financial Statements – (continued)December 31, 2021

Effective January 1, 2021, $656.5 million of assets in excess of the expected liability to cover the postretirement medical benefits for retirees were re-designated for non-retiree benefits. The elections were made pursuant to plan provisions, which provide for assets in excess of 125% of expected liabilities to fund other benefits covered under the plans. The re-designated assets, net of associated tax receivable impacts related to a tax adjustment to accumulated other comprehensive income, are not included as part of the asset balances presented in the footnote as they no longer qualify as plan assets in accordance with U.S. GAAP. The re-designated assets are included in equity securities and other investments on our consolidated statements of financial position beginning January 1, 2021.

Rate of compensation increase	N/A		N/A		N/A	%

(1)During the second quarter 2020, subsidy increases provided under the long-term care plan were capped at 5% per calendar year. This change was remeasured as of March 31, 2020. A discount rate of 2.95% was used until the remeasurement date at which time a discount rate of 2.90% was used.

For other postretirement benefits, the discount rate is determined by projecting future benefit payments inherent in the accumulated postretirement benefit obligation, and discounting those cash flows using a spot yield curve for high quality corporate bonds. The plans’ expected benefit payments are discounted to determine a present value using the yield curve and the discount rate is the level rate that produces the same present value. The 4.25% expected long-term return on plan assets for2021 was based on the weighted average expected long-term asset returns for the medical, life and long-term care plans. The expected long-term rates for the home office medical/life and agent medical/life plans were 4.25% and 4.25%, respectively.

Other Postretirement Benefit Plan Assets

Fair value is defined as the price that would be received to sell an asset in an orderly transaction between market participants at the measurement date (an exit price). The fair value hierarchy 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.

•Level 2 – Fair values are based on inputs other than quoted prices within Level 1 that are observable for the asset, either directly or indirectly.

•Level 3 – Fair values are based on significant unobservable inputs for the asset.

Our other postretirement benefit plan assets consist of cash, investments in fixed income security portfolios and investments in equity security portfolios. Because of the nature of cash, its carrying amount approximates fair value. The fair value of fixed income investment funds, U.S. equity portfolios and international equity portfolios is based on quoted prices in active markets for identical assets.

These include, but are not limited to, corporate bonds, residential mortgage-backed securities, commercial mortgage-backed securities, U.S. Treasury securities, agency securities, asset-backed securities and collateralized mortgage obligations.

(2)The portfolios invest primarily in publicly traded equity securities of large U.S. companies.

(3)The portfolios invest primarily in publicly traded equity securities of non-U.S. companies.

As of December 31, 2020, $117.6 million of assets in cash, fixed income security portfolios, U.S. equity portfolios and international equity portfolios were included in a trust owned life insurance contract. Effective January 1, 2021, these assets were redesignated for other welfare benefits.

    We have established an investment policy that provides the investment objectives and guidelines for the other postretirement benefit plans. Our investment strategy is to achieve the following:

•Obtain a reasonable long-term return consistent with the level of risk assumed and at a cost of operation within prudent levels. Performance benchmarks are monitored.

•Ensure sufficient liquidity to meet the emerging benefit liabilities for the plans.

•Provide for diversification of assets in an effort to avoid the risk of large losses and maximize the investment return to the other postretirement benefit plans consistent with market and economic risk.

    In administering the other postretirement benefit plans’ asset allocation strategies, we consider the projected liability stream of benefit payments, the relationship between current and projected assets of the plan and the projected actuarial liabilities streams, the historical performance of capital markets adjusted for the perception of future short- and long-term capital market performance and the perception of future economic conditions.

According to our investment policy, the target asset allocation for the other postretirement benefit plans is:

Asset category	Target allocation
Fixed income security portfolios	50%
U.S. equity portfolios	35%
International equity portfolios	15%

The assumptions used in calculating the estimated future benefit payments are the same as those used to measure the benefit obligation for the year ended December 31, 2021.

13. Contingencies, Guarantees, Indemnifications and Leases

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, individual life insurance, specialty benefits insurance and our investment activities. Some of the lawsuits may be class actions, or purport to be, and some may include claims for unspecified or substantial punitive and treble damages.

We may discuss such litigation in one of three ways. We accrue a charge to income and disclose legal matters for which the chance of loss is probable and for which the amount of loss can be reasonably estimated. We may disclose contingencies for which the chance of loss is reasonably possible and provide an estimate of the possible loss or range of loss or a statement that such an estimate cannot be made. Finally, we may voluntarily disclose loss contingencies for which the chance of loss is remote in order to provide information concerning matters that potentially expose us to possible losses.

In addition, regulatory bodies such as state insurance departments, the SEC, the Financial Industry Regulatory Authority, the Department of Labor and other regulatory agencies regularly make inquiries and conduct examinations or investigations concerning our compliance with, among other things, insurance laws, securities laws, Employee Retirement Income Security Act (“ERISA”) and laws governing the activities of broker-dealers. We receive requests from regulators and other governmental authorities relating to industry issues and may receive additional requests, including subpoenas and interrogatories, in the future.

On November 12, 2014, Frederick Rozo filed a class action lawsuit in the United States District Court for the Southern District of Iowa against us and PFG. PFG was later dismissed as a defendant. The Plaintiff alleged that defendants breached fiduciary duties and engaged in prohibited transactions under ERISA in connection with a general account guaranteed product known as the Principal Fixed Income Option (“PFIO”). On May 12, 2017, the district court certified a nationwide class of participants and beneficiaries who had funds invested in one of the PFIO contracts. On September 25, 2018, the district court granted our motion for summary judgment. On February 3, 2020, the Eighth Circuit Court of Appeals reversed that ruling and remanded the case back to the district court. A bench trial was held before the district court November 3-10, 2020. The court issued its ruling on April 8, 2021, and found in favor of us on all claims. The Plaintiff has appealed this ruling to the Eighth Circuit Court of Appeals. We will continue to aggressively defend the case.

While the outcome of any pending or future litigation or regulatory matter cannot be predicted, management does not believe any such matter will have a material adverse effect on our business or financial position. As of December 31, 2021, we had no estimated loss accrued related to the legal matter discussed above because we believe the chance of loss from this matter is not probable and the amount of loss cannot be reasonably estimated.

B-70

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2021

To the extent such matters present a reasonably possible chance of loss, we are generally not able to estimate the possible loss or range of loss associated therewith. The outcome of such matters is always uncertain and unforeseen results can occur. It is possible that such outcomes could require us to pay damages or make other expenditures or establish accruals in amounts that we could not estimate at December 31, 2021.

Guarantees and Indemnifications

    In the normal course of business, we have provided guarantees to our ultimate parent, PFG, related to benefit payments of the nonqualified pension plans and the nonqualified deferred compensation plans. We also provided guarantees to third parties primarily related to a former subsidiary. The terms of these agreements range in duration and often are not explicitly defined. The maximum exposure under these agreements as of December 31, 2021, was approximately $259.0 million. At inception, the fair value of such guarantees was insignificant. In addition, we believe the likelihood is remote that material payments will be required. Therefore, any liability accrued within our consolidated statements of financial position is insignificant. Should we be required to perform under these guarantees, we generally could recover a portion of the loss from third parties through recourse provisions included in agreements with such parties, the sale of assets held as collateral that can be liquidated in the event performance is required under the guarantees or other recourse generally available to us; therefore, such guarantees would not result in a material adverse effect on our business or financial position. While the likelihood is remote, such outcomes could materially affect net income in a particular quarter or annual period.

We are also subject to various other indemnification obligations issued in conjunction with divestitures, acquisitions and financing transactions whose terms range in duration and often are not explicitly defined. Certain portions of these indemnifications may be capped, while other portions are not subject to such limitations; therefore, the overall maximum amount of the obligation under the indemnifications cannot be reasonably estimated. At inception, the fair value of such indemnifications was insignificant. In addition, we believe the likelihood is remote that material payments will be required. Therefore, any liability accrued within our consolidated statements of financial position is insignificant. While we are unable to estimate with certainty the ultimate legal and financial liability with respect to these indemnifications, we believe that performance under these indemnifications would not result in a material adverse effect on our business or financial position. While the likelihood is remote, performance under these indemnifications could materially affect net income in a particular quarter or annual period.

Guaranty Funds

Under state insurance guaranty fund laws, insurers doing business in a state can be assessed, up to prescribed limits, for certain obligations of insolvent insurance companies to policyholders and claimants. A state’s fund assesses its members based on their pro rata market share of written premiums in the state for the classes of insurance for which the insolvent insurer was engaged. Some states permit member insurers to recover assessments paid through full or partial premium tax offsets. We accrue liabilities for guaranty fund assessments when an assessment is probable, can be reasonably estimated and when the event obligating us to pay has occurred. While we cannot predict the amount and timing of any future assessments, we have established reserves we believe are adequate for assessments relating to insurance companies that are currently subject to insolvency proceedings. As of December 31, 2021 and 2020, the liability balance for guaranty fund assessments, which is not discounted, was $21.0 million and $21.1 million, respectively, and was reported within other liabilities in the consolidated statements of financial position. As of December 31, 2021 and 2020, $9.7 million and $9.6 million, respectively, related to premium tax offsets were included in premiums due and other receivables in the consolidated statements of financial position.

Leases

    As a lessee, we lease office space, data processing equipment, office furniture and office equipment under various operating leases. We also lease buildings and hardware storage equipment under finance leases. Lease assets and liabilities are recognized at the commencement of a lease based on the present value of lease payments over the lease term. We generally use our incremental borrowing rate based on the information available at the lease commencement date to determine the present value of lease payments. Lease term may include options to extend or terminate the lease when it is reasonably certain we will exercise the option. Leases with an initial term of twelve months or less are not recorded on the consolidated statements of financial position. We recognize lease expense for leases on a straight-line basis over the lease term. Some of our lease agreements include payments for property taxes, insurance, utilities or common area maintenance, which are not based on an index or rate. These payments are recognized in net income in the period in which the obligation has occurred.

    We sublease certain office space to third parties, which are primarily operating leases. We record sublease income on a straight-line basis over the lease term.

Dividend Limitations

Under Iowa law, we may pay dividends or make other distributions only from the earned surplus arising from our business and must receive the prior approval of the Commissioner of Insurance of the State of Iowa (“the Commissioner”) to pay stockholder dividends or make any other distribution if such distribution would exceed certain statutory limitations. Iowa law gives the Commissioner discretion to disapprove requests for distributions in excess of these limitations. Extraordinary dividends include those made, together with dividends and other distributions, within the preceding twelve months that exceed the greater of (i) 10% of our statutory policyholder surplus as of the previous year-end or (ii) the statutory net gain from operations from the previous calendar year, not to exceed earned surplus. Based on this limitation and 2021 statutory results, we could pay approximately $961.7 million in ordinary stockholder dividends in 2022 without prior regulatory approval. However, because the dividend test is based on dividends previously paid over rolling 12-month periods, if paid before a specified date during 2022, some or all of such dividends may be extraordinary and require regulatory approval.

15. Fair Value Measurements

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. Certain financial instruments, particularly policyholder liabilities other than investment contracts, are excluded from these fair value disclosure requirements.

Valuation Hierarchy

Fair value is defined 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). The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three levels. The level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety considering factors specific to the asset or liability.

•Level 1 – Fair values are based on unadjusted quoted prices in active markets for identical assets or liabilities.

•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.

•Level 3 – Fair values are based on at least one significant unobservable input for the asset or liability.

Determination of Fair Value

The following discussion describes the valuation methodologies and inputs used for assets and liabilities measured at fair value on a recurring basis. The techniques utilized in estimating the fair value 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 based on available market information and judgments about the financial instrument at a specific point in time. 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 validated through an investment analyst review process, which includes validation through direct interaction with external sources and use of internal models or other relevant information. We did not make any significant changes toour valuation processes during2021.

Fixed Maturities

Fixed maturities include bonds, ABS, redeemable preferred stock and certain non-redeemable preferred securities. When available, the fair value of fixed maturities is based on quoted prices of identical assets in active markets. These are reflected in Level 1 and primarily include U.S. Treasury bonds and actively traded redeemable corporate preferred securities.

When quoted prices of identical assets in active markets are not available, our first priority is to obtain prices from third party pricing vendors. We have regular interaction with these vendors to ensure we understand their pricing methodologies and to confirm they are utilizing observable market information. Their methodologies vary by asset class and include inputs such as estimated cash flows, benchmark yields, reported trades, broker quotes, credit quality, industry events and economic events. Fixed maturities with validated prices from pricing services, which includes the majority of our public fixed maturities in all asset classes, are generally reflected in Level 2. Also included in Level 2 are corporate bonds when quoted market prices are not available, for which an internal model using substantially all observable inputs or a matrix pricing valuation approach is used. In the matrix approach, securities are grouped into pricing categories that vary by sector, rating and average life. Each pricing category is assigned a risk spread based on studies of observable public market data from the investment professionals assigned to specific security classes. The expected cash flows of the security are then discounted back at the current Treasury curve plus the appropriate risk spread. Although the matrix valuation approach provides a fair valuation of each pricing category, the valuation of an individual security within each pricing category may also be impacted by company specific factors.

If we are unable to price a fixed maturity security using prices from third party pricing vendors or other sources specific to the asset class, we may obtain a broker quote or utilize an internal pricing model specific to the asset utilizing relevant market information, to the extent available and where at least one significant unobservable input is utilized. These are reflected in Level 3 in the fair value hierarchy and can include fixed maturities across all asset classes. As of December 31, 2021, approximately 1% of our total fixed maturities were Level 3 securities valued using internal pricing models.

The primary inputs, by asset class, for valuations of the majority of our Level 2 investments from third party pricing vendors or our internal pricing valuation approach are described below.

Inputs include cash flows, priority of the tranche in the capital structure, expected time to maturity for the specific tranche, reinvestment period remaining and performance of the underlying collateral including prepayments, defaults, deferrals, loss severity of defaulted collateral and, for RMBS, prepayment speed assumptions. Other inputs include market indices and recently executed market transactions.

Equity Securities

Equity securities include mutual funds, common stock and non-redeemable preferred stock. Fair values of equity securities are determined using quoted prices in active markets for identical assets when available, which are reflected in Level 1. When quoted prices are not available, we may utilize internal valuation methodologies appropriate for the specific asset that use observable inputs such as underlying share prices or the net asset value (“NAV”), which are reflected in Level 2. Fair values might also be determined using broker quotes or through the use of internal models or analysis that incorporate significant assumptions deemed appropriate given the circumstances and consistent with what other market participants would use when pricing such securities, which are reflected in Level 3. 

Derivatives

The fair values of exchange-traded derivatives are determined through quoted market prices, which are reflected in Level 1. Exchange-traded derivatives include futures that are settled daily, which reduces their fair value in the consolidated statements of financial position. The fair values of OTC cleared derivatives are determined through market prices published by the clearinghouses, which are reflected in Level 2. The clearinghouses utilize the secured overnight financing rate (“SOFR”) curve in their valuation. Variation margin associated with OTC cleared derivatives is settled daily, which reduces their fair value in the consolidated statements of financial position. The fair values of bilateral OTC derivative instruments are determined using either pricing valuation models that utilize market observable inputs or broker quotes. The majority of our bilateral OTC derivatives are valued with models that use market observable inputs, which are reflected in Level 2. Significant inputs include contractual terms, interest rates, currency exchange rates, credit spread curves, equity prices and volatilities. These valuation models consider projected discounted cash flows, relevant swap curves and appropriate implied volatilities. Certain bilateral OTC derivatives utilize unobservable market data, primarily independent broker quotes that are nonbinding quotes based on models that do not reflect the result of market transactions, which are reflected in Level 3.

Our non-cleared derivative contracts are generally documented under ISDA Master Agreements, which provide for legally enforceable set-off and close-out netting of exposures to specific counterparties. Collateral arrangements are bilateral and based on current ratings of each entity. We utilize the SOFR curve to value our positions. Counterparty credit risk is routinely monitored to ensure our adjustment for nonperformance risk is appropriate. Our centrally cleared derivative contracts are conducted with regulated centralized clearinghouses, which provide for daily exchange of cash collateral or variation margin equal to the difference in the daily market values of those contracts that eliminates the nonperformance risk on these trades.

Interest Rate Contracts. For non-cleared contracts, which include interest rate swaps and have included swaptions, we use discounted cash flow valuation techniques to determine the fair value using observable swap curves as the inputs. These are reflected in Level 2. We have forward contracts for which we obtain prices from third party pricing vendors. These are reflected in Level 2. For centrally cleared contracts we use published prices from clearinghouses. These are reflected in Level 2. In addition, we had interest rate options that were valued using broker quotes. These were reflected in Level 3.

Foreign Exchange Contracts. We use discounted cash flow valuation techniques that utilize observable swap curves and exchange rates as the inputs to determine the fair value of foreign currency swaps. These are reflected in Level 2. Currency forwards are valued using observable market inputs, including forward currency exchange rates. These are reflected in Level 2. In addition, we had a limited number of non-standard currency swaps that were valued using broker quotes. These were reflected within Level 3.

Equity Contracts. We use an option pricing model using observable implied volatilities, dividend yields, index prices and swap curves as the inputs to determine the fair value of equity options. These are reflected in Level 2.

Credit Contracts. We use either the ISDA Credit Default Swap Standard discounted cash flow model that utilizes observable default probabilities and recovery rates as inputs to determine the fair value of credit default swaps. These are reflected in Level 2. In addition, we have a limited number of credit default swaps that are valued using broker quotes. These are reflected within Level 3.

Other Investments

Other investments reported at fair value include invested assets of consolidated sponsored investment funds, unconsolidated sponsored investment funds, other investment funds reported at fair value, equity method real estate investments for which the fair value option was elected and certain redeemable and nonredeemable preferred stock. In addition, in 2019 we had commercial mortgage loans of a consolidated VIE for which the fair value option was elected.

The fair value of investment funds is determined using the NAV of the fund. The NAV of the fund represents the price at which we would be able to initiate a transaction. Investments for which the NAV represents a quoted price in an active market for identical assets are reflected in Level 1. Investments that do not have a quoted price in an active market are reflected in Level 2.

Commercial mortgage loans of a consolidated VIE were valued using the more observable fair value of the liabilities of the consolidated collateralized financing entity under the measurement alternative guidance and were reflected in Level 2. The liabilities were affiliated so were not reflected in our consolidated results. The trust was unwound in the third quarter of 2019.

Equity method real estate investments for which the fair value option was elected were reflected in Level 3. The equity method real estate investments consisted of underlying real estate and debt. The real estate fair value was estimated using a discounted cash flow valuation model that utilized public real estate market data inputs such as transaction prices, market rents, vacancy levels, leasing absorption, market cap rates and discount rates. The debt fair value was estimated using a discounted cash flow analysis based on our incremental borrowing rate for similar borrowing arrangements. The last equity method real estate investment for which the fair value option was elected was sold in the third quarter of 2021.

The fair value of certain redeemable and nonredeemable preferred stock is based on an internal model using unobservable inputs, which is reflected in Level 3. The redeemable preferred stock was sold in the third quarter of 2020.

Cash Equivalents

Certain cash equivalents are reported at fair value on a recurring basis and include money market instruments and other short-term investments with maturities of three months or less. Fair values of these cash equivalents may be determined using public quotations, when available, which are reflected in Level 1. When public quotations are not available, because of the highly liquid nature of these assets, carrying amounts may be used to approximate fair values, which are reflected in Level 2.

Separate Account Assets

Separate account assets include equity securities, debt securities, cash equivalents and derivative instruments, for which fair values are determined as previously described, and are reflected in Level 1, Level 2 and Level 3. Separate account assets also include commercial mortgage loans, for which the fair value is estimated by discounting the expected total cash flows using market rates that are applicable to the yield, credit quality and maturity of the loans. The market clearing spreads vary based on mortgage type, weighted average life, rating and liquidity. These are reflected in Level 3. Finally, separate account assets include real estate, for which the fair value is estimated using discounted cash flow valuation models that utilize various public real estate market data inputs. In addition, each property is appraised annually by an independent appraiser. The real estate included in separate account assets is recorded net of related mortgage encumbrances for which the fair value is estimated using discounted cash flow analysis based on our incremental borrowing rate for similar borrowing arrangements. The real estate within the separate accounts is reflected in Level 3.

Investment and Universal Life Contracts

Certain universal life, annuity and other investment contracts include embedded derivatives that have been bifurcated from the host contract and are measured at fair value on a recurring basis, which are reflected in Level 3. The key assumptions for calculating the fair value of the embedded derivative liabilities are market assumptions (such as equity market returns, interest rate levels, market volatility and correlations) and policyholder behavior assumptions (such as lapse, mortality, utilization and withdrawal patterns). Risk margins are included in the policyholder behavior assumptions. The assumptions are based on a combination of historical data and actuarial judgment. The embedded derivative liabilities are valued using models that incorporate a spread reflecting our own creditworthiness. 

The assumption for our own nonperformance risk for investment contracts and any embedded derivatives bifurcated from certain universal life, annuity and investment contracts is based on the current market credit spreads for debt-like instruments we have issued and are available in the market.

Assets transferred into Level 3 during 2021, 2020 and 2019, primarily included those assets for which we are now unable to obtain pricing from a recognized third party pricing vendor as well as assets that were previously priced using a matrix valuation approach that may no longer be relevant when applied to asset-specific situations. In addition, other investments transferred from Level 2 into Level 3 during 2019, included certain redeemable preferred stock for which at least one significant unobservable input is now used to determine fair value.

Assets transferred out of Level 3 during 2021, 2020 and 2019, included those for which we are now able to obtain pricing from a recognized third party pricing vendor or from internal models using substantially all market observable information.

Quantitative Information about Level 3 Fair Value Measurements

The following table provides quantitative information about the significant unobservable inputs used for recurring fair value measurements categorized within Level 3, excluding assets and liabilities for which significant quantitative unobservable inputs are not developed internally, which primarily consists of those valued using broker quotes.

(6)Includes bifurcated embedded derivatives that are reported at net asset (liability) fair value within the same line item in the consolidated statements of financial position in which the host contract is reported.

Market comparable discount rates are used as the base rate in the discounted cash flows used to determine the fair value of certain assets. The use of a higher or lower discount rate would have caused the fair value of the assets to significantly decrease or increase, respectively. Additionally, we may adjust the base discount rate or the modeled price by applying an illiquidity premium given the highly structured nature of certain assets. The use of a higher or lower illiquidity premium would have caused significant decreases or increases, respectively, in the fair value of the asset.

Embedded derivatives within our investment and universal life contracts liability can be in either an asset or liability position, depending on certain inputs at the reporting date. Increases to an asset or decreases to a liability are described as increases to fair value. The use of a higher or lower market volatility would have caused significant decreases or increases, respectively, in the fair value of embedded derivatives in investment and universal life contracts. Long duration interest rates are used as the mean return when projecting the growth in the value of associated account value and impact the discount rate used in the discounted future cash flows valuation. The amount of claims will increase if account value is not sufficient to cover guaranteed withdrawals. The use of higher or lower risk-free rates would have caused the fair value of the embedded derivative to significantly increase or decrease, respectively. The use of a higher or lower rate for our own credit risks, which impact the rates used to discount future cash flows, would have significantly increased or decreased, respectively, the fair value of the embedded derivative.

The use of a lower or higher mortality rate assumption would have caused the fair value of the embedded derivative to decrease or increase, respectively. The use of a lower or higher overall lapse rate assumption would have caused the fair value of the embedded derivative to decrease or increase, respectively. The lapse rate assumption may vary dynamically based on the relationship of the guarantee and associated account value. A stronger or weaker dynamic lapse rate assumption would have caused the fair value of the embedded derivative to decrease or increase, respectively. The utilization rate assumption includes how many contractholders will take withdrawals, when they will take them and how much of their benefit they will take. The use of a higher or lower assumption of the number of contractholders taking withdrawals would have caused the fair value of the embedded derivative to decrease or increase, respectively. Assuming contractholders take withdrawals earlier or later would have caused the fair value of the embedded derivative to decrease or increase, respectively. Assuming contractholders take more or less of their benefit would have caused the fair value of the embedded derivative to decrease or increase, respectively.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

No significant assets and liabilities were measured at fair value on a nonrecurring basis for the years ended December 31, 2021, 2020 and 2019.

Fair Value Option

We elected fair value accounting for:

•Certain commercial mortgage loans of a consolidated VIE for which it was not practicable for us to determine the carrying value. The consolidated VIE was unwound in the third quarter of 2019.

•Certain real estate ventures that were subject to the equity method of accounting because the nature of the investments was to add value to the properties and generate income from the operations of the properties. Other equity method real estate investments were not fair valued because the investments mainly generated income from the operations of the underlying properties. The last equity method real estate investment for which the fair value option was elected was sold in the third quarter of 2021.

16. Statutory Insurance Financial Information

We, the largest indirect subsidiary of PFG, prepare statutory financial statements in accordance with the accounting practices prescribed or permitted by the Insurance Division of the Department of Commerce of the State of Iowa (the “Iowa Insurance Division”). The Iowa Insurance Division recognizes only statutory accounting practices prescribed or permitted by the State of Iowa for determining and reporting the financial condition and results of operations of an insurance company to determine its solvency under the Iowa Insurance Law. The National Association of Insurance Commissioners' (“NAIC”) Accounting Practices and Procedures Manual has been adopted as a component of prescribed practices by the State of Iowa. The Commissioner has the right to permit other specific practices that deviate from prescribed practices. Statutory accounting practices differ from U.S. GAAP primarily due to charging policy acquisition costs to expense as incurred, establishing reserves using different actuarial assumptions, valuing investments on a different basis and not admitting certain assets, including certain net deferred income tax assets.

We cede certain term and universal life insurance statutory reserves to our affiliated reinsurance subsidiaries on a funds withheld coinsurance basis. The reserves are secured by cash, invested assets and financing provided by highly rated third parties. As of December 31, 2021 and 2020, our affiliated reinsurance subsidiaries assumed statutory reserves of $10,085.7 million and $8,978.2 million from us, respectively. In the states of Vermont and Delaware, the affiliated reinsurers had permitted and prescribed practices allowing for the admissibility of certain assets backing these reserves. As of December 31, 2021 and 2020, assets admitted under these practices totaled $4,146.0 million and $3,731.0 million, respectively.

    Life and health insurance companies are subject to certain risk-based capital (“RBC”) requirements as specified by the NAIC. Under those requirements, the amount of capital and surplus maintained by a life and health insurance company is to be determined based on the various risk factors related to it. As of December 31, 2021, we met the minimum RBC requirements.

Our statutory net income and statutory capital and surplus were as follows:

	As of or for the year ended December 31,
	2021			2020			2019
	(in millions)
Statutory net income	$	864.0		$	915.9		$	989.3
Statutory capital and surplus			5,375.2			5,682.4			5,193.4

17. Revenues from Contracts with Customers

Administrative Service Fee Revenue

    We offer service and trust agreements for defined contribution retirement plans, including 401(k) plans, 403(b) plans, and employee stock ownership plans. The investment components of these service agreements are in the form of mutual fund offerings. In addition, plan sponsor retirement plan trust and custody services are also available through an affiliated trust company.

•Fees and other revenues are earned for administrative activities performed for the defined contribution retirement plans including recordkeeping and reporting as well as trust and custody, asset management and investment services. The majority of these activities are performed daily over time. Fee-for-service transactions are also provided upon client request. These services are considered distinct or grouped into a bundle until a distinct performance obligation is identified. Some performance obligations are considered a series of distinct services, which are substantially the same and have the same pattern of transfer to the customer.

•Fees and other revenues can be based on a fixed contractual rate for these services or can be variable based upon contractual rates applied to the market value of the client's investment portfolio each day. If the consideration for this series of performance obligations is based on daily market value, it is considered variable each day as the services are performed over time. The consideration becomes unconstrained and thus recognized as revenue for each day’s series of distinct services once the market value of the clients’ investment portfolios is determined at market close or carried over at the end of the day for days when the market is closed. Additionally, fixed fees and other revenues are recognized point-in-time as fee-for-service transactions upon completion.

We offer administrative services performed for our fee-for-service products, nonqualified benefit plans, separate accounts and dental networks.

•Fees and other revenues are earned for administrative services performed, which include recordkeeping and reporting services. Services within contracts are not distinct on their own; however, we combine the services into a distinct bundle and account for the bundle as a single performance obligation, which is satisfied over time utilizing the output method as services are rendered. The transaction price corresponds with the performance completed to date, for which the value is recognized as revenue during the period. Variability of consideration is resolved at the end of each period and payments are due when billed.

Deposit Account Fee Revenue

    We offer individual retirement accounts (“IRAs”) through Principal Bank, which are primarily funded by retirement savings rolled over from qualified retirement plans. The IRAs are held in savings accounts, money market accounts and certificates of deposit. Revenues are earned through fees as the performance of establishing and maintaining IRA accounts is completed. Fee-for-service transactions are also provided upon client request. The establishment fees and annual maintenance fees are accrued into earnings over a period of time using the average account life. Upfront and recurring bank fees are related to performance obligations that have the same pattern of transfer to the customer and are recognized in income over time with control transferred to the customers utilizing the output method. These fees are based on a fixed contractual rate. Fixed fees and other revenues are also recognized point-in-time as fee-for-service transactions upon completion.

Commission Income

Commission income is earned through sponsored brokerage services. Performance obligations are satisfied at a point in time, upon delivery of a placed case, and the transaction price calculated per the compensation schedule is recognized as revenue. Additionally, commission income is earned on advisory services provided to customers. The revenues are earned over time as the service is performed based upon contractual rates applied to the market value of the clients’ portfolios.

Disaggregation of Revenues from Contracts with Customers

    The following table summarizes the disaggregation of revenues from contracts with customers and reconciles totals to those reported in the consolidated financial statements. Revenues from contracts with customers are included in fees and other revenues on the consolidated statements of operations.

		For the year ended December 31,
		2021			2020			2019
		(in millions)
Administrative service fee revenue		$	432.7		$	280.9		$	283.2
Deposit account fee revenue				9.2			8.4			9.3
Commission income				34.6			27.0			26.9
Other fee revenue				3.8			2.4			2.5
	Total revenues from contracts with customers			480.3			318.7			321.9
Fees and other revenues not within the scope of revenue
	recognition guidance (1)			2,199.3			2,034.9			2,074.8
Total fees and other revenues per consolidated statements of
	operations	$	2,679.6		$	2,353.6		$	2,396.7

(1)     Fees and other revenues not within the scope of the revenue recognition guidance primarily represent revenue on contracts accounted for under the financial instruments or insurance contracts standards.

Contract Costs

    Sales compensation and other incremental costs of obtaining a contract are capitalized and amortized over the period of contract benefit if the costs are expected to be recovered. The contract cost asset, which is included in other assets on the consolidated statements of financial position, was $41.8 million and $40.9 million as of December 31, 2021 and 2020, respectively.

We apply the practical expedient for certain costs where we recognize the incremental costs of obtaining these contracts as an expense when incurred if the amortization period of the assets is one year or less. These costs, along with costs that are not deferrable, are included in operating expenses on the consolidated statements of operations.

Deferred contract costs consist primarily of commissions and variable compensation. We amortize capitalized contract costs on a straight-line basis over the expected contract life, reflecting lapses as they are incurred. Deferred contract costs are subject to impairment testing on an annual basis, or when a triggering event occurs that could warrant an impairment. To the extent future revenues less future maintenance expenses are not adequate to cover the asset balance, an impairment is recognized. For the years ended December 31, 2021, 2020 and 2019, $7.3 million, $7.2 million and $7.5 million, respectively, of amortization expense was recorded in operating expenses on the consolidated statements of operations and no impairment loss was recognized in relation to the costs capitalized.

18. Stock-Based Compensation Plans

As of December 31, 2021, our ultimate parent, PFG, sponsored the 2021 Stock Incentive Plan, the 2014 Stock Incentive Plan, the Employee Stock Purchase Plan, the Amended and Restated 2010 Stock Incentive Plan and the Stock Incentive Plan ("Stock-Based Compensation Plans"), which resulted in expense to us. No new grants will be made under the 2014 Stock Incentive Plan, the Amended and Restated 2010 Stock Incentive Plan or the Stock Incentive Plan. Under the terms of the 2021 Stock Incentive Plan grants may be nonqualified stock options, incentive stock options qualifying under Section 422 of the Internal Revenue Code, restricted stock, restricted stock units, stock appreciation rights, performance shares, performance units or other stock-based awards. To date, PFG has not granted any incentive stock options, restricted stock or performance units under any plans.As part of our fair value process, for each stock-based compensation plan, we assess the impact of material nonpublic information on PFG’s share price or expected volatility, as applicable, at the time of grant. No awards in 2021 required a fair value adjustment.

B-94

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2021

For awards with graded vesting, we use an accelerated expense attribution method. The compensation cost that was charged against net income for stock-based awards granted under the Stock-Based Compensation Plans was as follows:

	For the year ended December 31,
	2021			2020			2019
	(in millions)
Compensation cost	$	25.2		$	24.4		$	21.9
Related income tax benefit			4.3			4.0			4.1
Capitalized as part of an asset			1.4			1.5			1.7

Nonqualified Stock Options

    Nonqualified stock options were granted to certain employees under the 2014 Stock Incentive Plan, the Amended and Restated 2010 Stock Incentive Plan and the Stock Incentive Plan. Options outstanding were granted at an exercise price equal to the fair market value of PFG common stock on the date of grant and expire ten years after the grant date. These options have graded vesting over a three-year period, except in the case of specific types of terminations.

    The fair value of stock options is estimated using the Black-Scholes option pricing model. The following is a summary of the assumptions used in this model for the stock options granted during the period:

	For the year ended December 31,
Options	2021				2020				2019
Expected volatility			34.2	%			25.7	%			23.3	%
Expected term (in years)			7.0				7.0				7.0
Risk-free interest rate			1.2	%			1.3	%			2.6	%
Expected dividend yield			3.82	%			4.33	%			4.07	%
Weighted average estimated fair value	$	15.67			$	9.64			$	10.00

We determine expected volatility based on a combination of historical volatility using daily price observations and implied volatility from traded options on PFG common stock. We believe that incorporating both historical and implied volatility into our expected volatility assumption calculation better reflects market expectations. The expected term represents the period of time that options granted are expected to be outstanding. We determine expected term using historical exercise and employee termination data. The risk-free rate for periods within the expected term of the option is based on the U.S. Treasury risk-free interest rate in effect at the time of grant. The dividend yield is based on historical dividend distributions compared to the closing price of PFG common shares on the grant date.

    As of December 31, 2021, we had $2.4 million of total unrecognized compensation cost related to nonvested stock options. The cost is expected to be recognized over a weighted-average service period of approximately 1.8 years.

Performance Share Awards

    Performance share awards were granted to certain employees under the 2014 Stock Incentive Plan and the Amended and Restated 2010 Stock Incentive Plan. The performance share awards are treated as an equity award and are paid in shares. Whether the performance shares are earned depends upon the participant's continued employment through the performance period (except in the case of specific types of terminations) and PFG’s performance against three-year goals set at the beginning of the performance period. Performance goals based on various PFG factors must be achieved for any of the performance shares to be earned. If the performance requirements are not met, the performance shares will be forfeited, no compensation cost will be recognized and any previously recognized compensation cost will be reversed. These awards have no maximum contractual term. Dividend equivalents are credited on performance shares outstanding as of the record date. These dividend equivalents are only paid on the shares released.

The fair value of performance share awards is determined based on the closing stock price of PFG common shares on the grant date. The weighted-average grant-date fair value of performance share awards granted during 2021, 2020 and 2019 was $58.68, $51.73 and $53.09, respectively.

As of December 31, 2021, we had $4.0 million of total unrecognized compensation cost related to nonvested performance share awards granted. The cost is expected to be recognized over a weighted-average service period of approximately 1.8 years.

Restricted Stock Units

    Restricted stock units were granted to certain employees and agents under the 2021 Stock Incentive Plan and the 2014 Stock Incentive Plan. Restricted stock units are treated as equity awards and are paid in shares. Under these plans, awards have graded or cliff vesting over a three-year service period. When service for PFG ceases (except in the case of specific types of terminations), all vesting stops and unvested units are forfeited. These awards have no maximum contractual term. Dividend equivalents are credited on restricted stock units outstanding as of the record date. These dividend equivalents are only paid on the shares released.

The fair value of restricted stock units is determined based on the closing stock price of PFG common shares on the grant date. The weighted-average grant-date fair value of restricted stock units granted during 2021, 2020 and 2019 was $59.38, $49.33 and $53.19, respectively.

As of December 31, 2021, we had $22.1 million of total unrecognized compensation cost related to nonvested restricted stock unit awards granted under these plans. The cost is expected to be recognized over a weighted-average period of approximately 1.7 years.

Employee Stock Purchase Plan

    Under the Employee Stock Purchase Plan, participating employees have the opportunity to purchase shares of PFG common stock on a quarterly basis. Employees may purchase up to $25,000 in PFG stock value annually. Employees were able to purchase shares of PFG common stock at a price equal to 85% of the shares' fair market value as of the beginning or end of the purchase period, whichever was lower, through 2021. Beginning January 2022, employees may purchase shares of PFG common stock at a price equal to 90% of the shares' fair market value as of the end of the purchase period.

    We recognize compensation expense for the fair value of the discount granted to employees participating in the employee stock purchase plan in the period of grant. Shares of the Employee Stock Purchase Plan are treated as an equity award. The weighted-average fair value of the discount on the stock purchased was $15.64, $11.33 and $11.37 during 2021, 2020 and 2019, respectively.
