⁽¹⁾   This underlying mutual fund is a fund of funds. The fund of funds expenses may be higher than other fund types because the expenses of the selected fund include the expenses of the funds it holds.

An investment in the Contract is not a deposit or obligation of any bank and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency.

The Contract offered by this prospectus may not be available in all states. This prospectus is not an offer to sell, or solicitation of an offer to buy, the Contract in states in which the offer or solicitation may not be lawfully made. No person is authorized to give any information or to make any representation in connection with this Contract other than those contained in this prospectus.

The Contract is available with or without the Purchase Payment Credit Rider. This rider applies credits to the accumulated value for purchase payments made in contract year one. The amount of the credit may be more than offset by the additional charges associated with it (higher surrender charges, a longer surrender charge period and increased annual expenses). A Contract without this rider will cost less. You should review your own circumstances to determine whether this rider is suitable for you. To assist you in making that determination, we have highlighted in grey boxes those portions of this prospectus pertaining to the rider.

NOTE: We recapture the purchase payment credit if you return the Contract during the examination offer period. You take the risk that the recaptured amount may exceed the then current value of the credit(s). This risk occurs when your investment options have experienced negative investment performance (i.e., have lost value) since the credit was applied. In that situation, you would be worse off than if you had not purchased the credit option.

These securities have not been approved or disapproved by the SEC or any state securities commission nor has the SEC or any state securities commission passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

This prospectus is valid only when accompanied by the current prospectuses for the underlying mutual funds. These prospectuses should be kept for future reference.

Example

The example is intended to help you compare the cost of investing in the contract with the cost of investing in other variable annuity contracts. These costs include contract owner transaction expenses, contract fees, separate account annual expenses, and underlying mutual fund fees and expenses. Although your actual costs may be higher or lower, based on these assumptions, your costs would be as shown below.

Contract with Purchase Payment Credit Rider.

This example reflects the maximum charges imposed if you were to purchase the Contract with the Purchase Payment Credit Rider. This example reflects the maximum and minimum annual underlying mutual fund operating expenses as of December 31, 2019 (without voluntary waiver of fees by the underlying funds, if any). This example assumes:

• a $10,000 investment in the Contract for the time periods indicated;

• a 5% return each year;

• an annual contract fee of $30 (expressed as a percentage of the average accumulated value); and

• the Purchase Payment Credit Rider was added to the Contract at issue and the Purchase Payment Credit Rider surrender charge schedule is applied. Because the purchase payment credit can not be added to the accumulated value in these examples, the Purchase Payment Credit Rider charges included below are not representative of the actual costs.

SUMMARY

This prospectus describes an individual flexible premium variable annuity offered by the Company. The Contract is designed to provide individuals with retirement benefits, including:

• Individual Retirement Annuities (“IRAs”), Simplified Employee Pension plans (“SEPs”) and Savings Incentive Match Plan for Employees (“SIMPLE”) IRAs adopted according to Section 408 of the Internal Revenue Code (see FEDERALTAX MATTERS — IRA, SEP and SIMPLE — IRA and Rollover IRAs); and

• non-qualified retirement programs.

The Contract does not provide any additional tax deferral if you purchase it to fund an IRA or other investment vehicle that already provides tax deferral.

This is a brief summary of the Contract’s features. More detailed information follows later in this prospectus.

Investment Limitations

• The initial purchase payment must be $2,500 or more for non-qualified retirement programs.

• The initial purchase payment must be $1,000 for all other contracts.

• Each subsequent purchase payment must be at least $100.

• If you are a member of a retirement plan covering three or more persons and purchase payments are made through an automatic investment program, then the initial and subsequent purchase payments for the Contract must average at least $100 and not be less than $50.

You may allocate your net purchase payments to the investment options.

• A complete list of the divisions may be found in the TABLEOF SEPARATE ACCOUNT DIVISIONS. Each division invests in shares of an underlying mutual fund. More detailed information about the underlying mutual funds may be found in the current prospectus for each underlying mutual fund.

• The investment options also include the Fixed Account and the DCA Plus Accounts.

10

Transfers (See Division Transfers and Fixed Account Transfers, Total andPartial Surrenders for additional restrictions.)

This section does not apply to transfers under the DCA Plus Program (see ScheduledDCA Plus Transfers and Unscheduled DCA Plus Transfers).

During the accumulation period:

• a dollar amount or percentage of transfer must be specified;

• a transfer may occur on a scheduled or unscheduled basis;

• transfers to the Fixed Account are not permitted if a transfer has been made from the Fixed Account to a division within six months; and

• transfers into DCA Plus Accounts are not permitted.

During the annuity benefit payment period, transfers are not permitted (no transfers once annuity payments have begun).

Surrenders (See Surrenders and Fixed Account Transfers, Total and PartialSurrenders and DCA Plus Surrenders)

During the accumulation period:

• a dollar amount must be specified;

• surrendered amounts may be subject to a surrender charge:

• for Contracts without the Purchase Payment Credit Rider, the maximum surrender charge is 6% of the amount surrendered.

• for Contracts with the Purchase Payment Credit Rider, the maximum surrender charge is 8% of the amount surrendered.

• total surrenders may be subject to an annual Contract fee;

• during a contract year, partial surrenders less than the Contract’s earnings or 10% of purchase payments are not subject to a surrender charge; and

• withdrawals before age 59 ½ may involve an income tax penalty (see FEDERAL TAX MATTERS).

Principal^® Variable Annuity Exchange Offer(“exchange offer”)

Original ownersof an eligible Principal^® Variable Annuity (Flexible Variable Annuity) contract may elect to exchange their Principal^® Variable Annuity (Flexible Variable Annuity) contract (“old contract”) for a new Principal^® Lifetime Income Solutions II Variable Annuity contract (“new contract”) subject to the exchange offer terms and conditions. To determine if it is in your best interest to participate in the exchange offer, we recommend that you consult with your tax advisor and financial professional before electing to participate in the exchange offer.

You are eligible to participate in the exchange offer when:

•your old contract is not subject to any surrender charges; and

•the exchange offer is available in your state.

Currently, there is no closing date for the exchange offer. We reserve the right, however, to modify or terminate the exchange offer upon reasonable written notice to you.

See Appendix A for further details about the exchange offer.

NOTE: There is no longer an exchange offer that allows you to purchase the Principal^® Investment Plus Variable Annuity.

Charges and Deductions

• There is no sales charge imposed on purchase payments.

• A contingent deferred surrender charge is imposed on certain total or partial surrenders.

• An annual mortality and expense risks charge equal to 1.25% of amounts in the Separate Account divisions is imposed daily.

• Optional riders are available at an additional charge (see CHARGES AND DEDUCTIONS).

• The Daily Separate Account administration charge is currently 0.05%, but we reserve the right to assess a charge not to exceed 0.15% of Separate Account division value(s) annually.

• Contracts with an accumulated value of less than $30,000 are subject to an annual fee of the lesser of $30 or 2% of the accumulated value. Currently we do not charge the annual fee if your accumulated value is $30,000 or more. If you own more than one Variable Annuity Contract with us, then all the Contracts you own or jointly own may be aggregated on each Contract’s anniversary, to determine if the $30,000 minimum has been met and whether that contract will be charged.

11

• Certain states and local governments impose a premium tax. The Company reserves the right to deduct the amount of the tax from purchase payments or accumulated value.

Annuity Benefit Payments

• You may choose from several fixed annuity benefit payment options which start on your selected annuitization date.

• Annuity benefit payments are made to the owner (or beneficiary depending on the annuity benefit payment option selected). You should carefully consider the tax implications of each annuity benefit payment option (see Annuity Benefit Payment Options and FEDERAL TAXMATTERS).

• Your Contract refers to annuity benefit payments as “retirement benefit” payments.

Death Benefit

• If the annuitant or owner dies before the annuitization date, then a death benefit is payable to the beneficiary of the Contract.

• The death benefit may be paid as either a single payment or under an annuity benefit payment option (see DeathBenefit).

• If the annuitant dies on or after the annuitization date, then the beneficiary will receive only any continuing annuity benefit payments which may be provided by the annuity benefit payment option in effect.

Examination Period (free look)

• You may return the Contract during the examination period which is generally 10 days from the date you receive the Contract. The examination period may be longer in certain states.

• We return all purchase payments if required by state law. Otherwise, we return accumulated value

• We retain the full amount of any purchase payment credit.

FLEXIBLE VARIABLE ANNUITY

The Flexible Variable Annuity is significantly different from a fixed annuity. As the owner of a variable annuity, you assume the risk of investment gain or loss (as to amounts in the divisions) rather than the insurance company. The Separate Account accumulated value under a variable annuity is not guaranteed and varies with the investment performance of the underlying mutual funds.

Based on your investment objectives, you direct the allocation of purchase payments and accumulated values. There can be no assurance that your investment objectives will be achieved.

THE COMPANY

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. Our home office is located at: Principal Financial Group, Des Moines, Iowa 50392. We are 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, we were incorporated under Iowa law as a mutual assessment life insurance company named Bankers Life Association. We became a legal reserve life insurance company and changed our name to Bankers Life Company in 1911. In 1986, we changed our name to Principal Mutual Life Insurance Company. In 1998, we 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 our current organizational structure.

THE SEPARATE ACCOUNT

Principal Life Insurance Company Separate Account B was established under Iowa law on January 12, 1970, and was registered as a unit investment trust with the SEC on July 17, 1970. This registration does not involve SEC supervision of the investments or investment policies of the Separate Account. We do not guarantee the investment results of the Separate Account. There is no assurance that the value of your Contract will equal the total of the payments you make to us.

12

The Separate Account is not affected by the rate of return of our General Account or by the investment performance of any of our other assets. Any income, gain, or loss (whether or not realized) from the assets of the Separate Account are credited to or charged against the Separate Account without regard to our other income, gains, or losses. Obligations arising from the Contract, including the promise to make annuity benefit payments, are general corporate obligations of the Company. Assets of the Separate Account attributed to the reserves and other liabilities under the Contract may not be charged with liabilities arising from any of our other businesses.

The Separate Account is divided into divisions. The assets of each division invest in a corresponding underlying mutual fund. New divisions may be added and made available. Divisions may also be eliminated from the Separate Account following SEC approval.

THE UNDERLYING MUTUAL FUNDS

The underlying mutual funds are registered under the Investment Company Act of 1940 as open-end investment management companies. The underlying mutual funds provide the investment vehicles for the Separate Account. Full descriptions of the underlying mutual funds, the investment objectives, policies and restrictions, charges and expenses and other operational information are contained in the accompanying prospectuses (which should be read carefully before investing) and the Statement of Additional Information (“SAI”). You may request additional copies of these documentswithout charge from your registered representative or by calling us at1-800-852-4450.

We purchase and sell shares of the underlying mutual fund for the Separate Account at their net asset value. Shares represent interests in the underlying mutual fund available for investment by the Separate Account. Each underlying mutual fund corresponds to one of the divisions. The assets of each division are separate from the others. A division’s performance has no effect on the investment performance of any other division.

The underlying mutual funds are NOT available to the general public directly. The underlying mutual funds are available only as investment options in variable life insurance policies or variable annuity contracts issued by life insurance companies and qualified plans. Some of the underlying mutual funds have been established by investment advisers that manage publicly traded mutual funds having similar names and investment objectives. While some of the underlying mutual funds may be similar to, and may in fact be modeled after publicly traded mutual funds, you should understand that the underlying mutual funds are not otherwise directly related to any publicly traded mutual fund. Consequently, the investment performance of any underlying mutual fund may differ substantially from the investment performance of a publicly traded mutual fund.

The Table of Separate Account Divisions later in this prospectus contains a brief summary of the investment objectives and a listing of the advisor and, if applicable, sub-advisor for each division.

Deletion or Substitution of Divisions

We reserve the right, within the law, to make additions, deletions and substitutions for the divisions. We will make no such substitution or deletion without first notifying you and obtaining approval of the appropriate insurance regulatory authorities and the SEC (to the extent required by 1940 Act).

If the shares of a division are no longer available for investment or if, in the judgment of our management, investment in a division becomes inappropriate for the purposes of our contract, we may eliminate the shares of a division and substitute shares of another division of the Trust or another open-end registered investment company. Substitution may be made with respect to both existing investments and the investment of future premium payments.

If we eliminate divisions, you may change allocation percentages and transfer any value in an affected division to another division(s) without charge. You may exercise this exchange privilege until the later of 60 days after a) the effective date of the additions, deletions and/or substitutions of the change, or b) the date you receive notice of the options available. You may only exercise this right if you have any value in the affected division(s).

We also reserve the right to establish additional divisions, each of which would invest in a separate underlying mutual fund with a specified investment objective.

Voting Rights

We vote shares of the underlying mutual funds owned by the Separate Account according to the instructions of owners.

We will notify you of shareholder meetings of the mutual funds underlying the divisions in which you hold units. We will send you proxy materials and instructions for you to provide voting instructions to us. We will arrange for the handling and tallying of proxies received from you and other owners. If you give no voting instructions, we will vote those shares in the same proportion as shares for which we received instructions.

13

We determine the number of fund shares that you may instruct us to vote by allocating one vote for each $100 of accumulated contract value in the division. Fractional votes are allocated for amounts less than $100. We determine the number of underlying fund shares you may instruct us to vote as of the record date established by the mutual fund for its shareholder meeting. In the event that applicable law changes or we are required by regulators to disregard voting instructions, we may decide to vote the shares of the underlying mutual funds in our own right.

NOTE: Because there is no required minimum number of votes, a small number of votes can have a disproportionate effect.

THE CONTRACT

The following descriptions are based on provisions of the Contract offered by this prospectus. You should refer to the actual Contract and the terms and limitations of any qualified plan which is to be funded by the Contract. Qualified plans are subject to several requirements and limitations which may affect the terms of any particular Contract or the advisability of taking certain action permitted by the Contract.

To Buy a Contract

If you want to buy a Contract, you must submit an application and make an initial purchase payment. If you are buying the Contract to fund a SIMPLE-IRA or SEP, an initial purchase payment is not required at the time you send in the application. If the application is complete and the Contract applied for is suitable, the Contract is issued. If the completed application is received in proper order, the initial purchase payment is credited within two valuation days after the later of receipt of the application or receipt of the initial purchase payment at our home office. If the initial purchase payment is not credited within five valuation days, it is refunded unless we have received your permission to retain the purchase payment until we receive the information necessary to issue the Contract.

The date the Contract is issued is the contract date. The contract date is the date used to determine contract years, regardless of when the Contract is delivered.

Tax-qualified retirement arrangements, such as IRAs, SEPs, and SIMPLE-IRAs, are tax-deferred. You derive no additional benefit from the tax deferral feature of the annuity. Consequently, an annuity should be used to fund an IRA, or other tax qualified retirement arrangement to benefit from the annuity’s features other than tax deferral. These features may include guaranteed lifetime income, death benefits without surrender charges, guaranteed caps on fees, and the ability to transfer among investment options without sales or withdrawal charges.

Purchase Payments

• The initial purchase payment must be at least $2,500 for non-qualified retirement programs.

• All other initial purchase payments must be at least $1,000.

• If you are making purchase payments through a payroll deduction plan or through a bank account (or similar financial institution) under an automated investment program, then your initial and subsequent purchase payments must be at least $100.

• All purchase payments are subject to a surrender charge period that begins in the contract year each purchase payment is received.

• Payments may be made via personal or financial institution check (for example, a bank or cashier’s check). We reserve the right to refuse any payment that we feel presents a fraud or money laundering risk. Examples of the types of payments we will not accept are cash, money orders, starter checks, travelers checks, credit card checks, and foreign checks.

• Subsequent purchase payments must be at least $100 and can be made until the annuitization date.

• If you are a member of a retirement plan covering three or more persons, then the initial and subsequent purchase payments for the Contract must average at least $100 and cannot be less than $50.

• The total of all purchase payments may not be greater than $2,000,000 without our prior approval.

• In New Jersey after the first contract year, purchase payments cannot exceed $100,000 per contract year.

Right to Examine the Contract (free look)

It is important to us that you are satisfied with the purchase of your Contract. Under state law, you have the right to return the Contract for any reason during the examination offer period (a “free look”). The examination offer period is the later of 10 days after the Contract is delivered to you, or such later date as specified by applicable state law.

14

Although we currently allocate your initial purchase payments to the investment options you have selected, we reserve the right to allocate initial purchase payments to the Money Market Division during the examination offer period. In addition, we are required to allocate initial purchase payments to the Money Market Division if the contract is issued in California and the owner is age 60 or older. After the examination offer period expires, your accumulated value will be converted into units of the divisions according to your allocation instructions. The units allocated will be based on the unit value next determined for each division.

NOTE: All references to the Money Market Division in this prospectus will mean the Fidelity VIP Government Money Market Division.

If you properly exercise your free look, we will rescind the Contract and we will pay you a refund of your current accumulated value plus any premium tax charge deducted, less any applicable federal and state income tax withholding and depending on the state in which the Contract was issued, any applicable fees and charges. The amount returned to you may be higher or lower than the purchase payment(s) applied during the examination offer period. Some states require us to return to you the amount of your purchase payment(s); if so, we will return the greater of your purchase payments or your current accumulated value plus any premium tax charge deducted, less any applicable federal and state income tax withholding and depending upon the state in which the Contract was issued, any applicable fees and charges.

NOTE: Please note that we recapture the purchase payment credit if you decide to return the Contract during the examination offer period. We recover the full amount of the purchase payment credit and you could receive less than your initial purchase payment.

If you are purchasing this Contract to fund an IRA, SIMPLE-IRA, or SEP-IRA and you return it on or before the seventh day of the examination offer period, we will return the greater of:

• the total purchase payment(s) made; or

• your accumulated value plus any premium tax charge deducted, less any applicable federal and state income tax withholding and depending upon the state in which the Contract was issued, any applicable fees and charges.

You may obtain more specific information regarding the free look from your registered representative or by calling us at 1-800-852-4450.

Purchase Payment Credit Rider

The Purchase Payment Credit Rider applies credits to the accumulated value for purchase payments made in contract year one. This rider may not be available in all states and may be subject to additional restrictions. Some rider provisions may vary from state to state. We may withdraw or prospectively restrict the availability of this rider at any time. For information regarding availability of this rider, you may contact your registered representative or call us at 1-800-852-4450.

This rider can only be elected at the time the Contract is issued. Once this rider is elected, it cannot be terminated.

If you elect this rider, the following provisions apply to the Contract:

• We will apply a credit of 5% of the purchase payment to your accumulated value for each purchase payment received during your first contract year on the date each purchase payment is applied to the Contract. For example, if you make a purchase payment of $10,000 in your first contract year, a credit amount of $500 will be added to your accumulated value (5% x $10,000).

• No credit(s) are applied to your accumulated value for purchase payments made after the first contract year.

• The credit is allocated among the investment options according to your then current purchase payment allocations.

• If you decide to return your Contract during the examination offer period, we recapture the credit(s) from your investment options according to your surrender allocation percentages (if surrender allocation percentages are not specified, we use your purchase payment allocation percentages). The amount we recapture could be more than the current value of the credit(s). If the investment options have experienced negative investment performance you bear the loss for the difference between the original value of the credit(s) (the amount recaptured) and the current (lower) value of the credit(s).

• Credits are considered earnings under the Contract, not purchase payments.

• All purchase payments are subject to the 9-year surrender charge table (see CHARGES AND DEDUCTIONS — Surrender Charge).

• The Purchase Payment Credit Rider can not be cancelled and the associated 9-year surrender charge period cannot be changed.

• You can not participate in the DCA Plus Program.

15

If you elect the Purchase Payment Credit Rider, your unit values will be lower than if you did not elect the rider. The difference reflects the annual charge for the Purchase Payment Credit Rider. In order to stop assessing the annual charge for the Purchase Payment Credit Rider, there will be a one time adjustment to the number of units in each division at the completion of the eighth contract year. The unit value used to calculate your accumulated value will increase at that time to reflect there is no longer an annual charge for the Purchase Payment Credit Rider. Therefore, to maintain your accumulated value, the number of units in each division will decrease. The following example is provided to assist you in understanding the one time adjustment at the completion of the eighth contract year.

	Sample Division Unit Value	Number of Units in Sample Division	Accumulated Value
Prior to the one time adjustment	25.560446	1,611.0709110	$41,179.69
After the one time adjustment	26.659024	1,544.6811189	$41,179.69

You should carefully examine the Purchase Payment Credit Rider to decide if this rider is suitable for you as there are circumstances under which you would be worse off for having received the credit. In making this determination, you should consider the following factors:

• the length of time you plan to own your Contract (this rider increases the amount and duration of the surrender charges, see CHARGES AND DEDUCTIONS — Surrender Charge);

• the amount and timing of your purchase payment(s). Any purchase payments made after the first contract year will be assessed higher Separate Account charges although no credit is applied to those purchase payments; and

• the higher Separate Account charges have a negative impact on investment performance.

The charges used to recoup our cost for the purchase payment credit(s) include the surrender charge and the Purchase Payment Credit Rider charge. The current charge for the rider is 0.60% of the average daily net assets of the annuitization date.

The following tables demonstrate hypothetical surrender values for Contracts with and without this rider but do not show the impact of partial surrenders. The tables are based on:

• a $25,000 initial purchase payment and no additional purchase payments;

• the deduction of total Separate Account annual expenses:

•Contracts with the Purchase Payment Credit Rider:

•2.00% annually for the first eight contract years

•1.40% annually after the first eight contract years

•Contracts without the Purchase Payment Credit Rider:

•1.40% annually for all contract years.

• the deduction of the arithmetic average of the underlying mutual fund expenses as of December 31, 2019;

• 0%, 5% and 10% annual rates of return before charges; and

• payment of the $30 annual contract fee (while the Contract’s value is less than $30,000).

The higher the rate of return, the more advantageous the Purchase Payment Credit Rider becomes. However, Contracts with the Purchase Payment Credit Rider are subject to both a greater surrender charge and a longer surrender charge period than Contracts issued without the Purchase Payment Credit Rider. If you surrender your Contract with the Purchase Payment Credit Rider while subject to a surrender charge, your surrender value may be less than the surrender value of a Contract without the Purchase Payment Credit Rider.

The Accumulation Period

The Value of Your Contract

The value of your Contract is the total of the Separate Account accumulated value plus the DCA Plus Account(s) accumulated value plus the Fixed Account accumulated value. The DCA Plus Accounts and Fixed Account are described in the section titled FIXED ACCOUNT AND DCA PLUS ACCOUNTS.

There is no guaranteed minimum Separate Account accumulated value. Its value reflects the investment experience of the divisions that you choose. It also reflects your purchase payments, partial surrenders, surrender charges and the Contract expenses deducted from the Separate Account.

The Separate Account accumulated value changes from day to day. To the extent the accumulated value is allocated to the Separate Account, you bear the investment risk. At the end of any valuation period, your Contract’s value in a division is:

•the number of units you have in a division multiplied by

•the value of a unit in the division.

The number of units is the total of units purchased by allocations to the division from:

•your initial purchase payment;

•subsequent purchase payments;

•purchase payment credits; and

•transfers from another division, a DCA Plus Account or the Fixed Account.

minus units sold:

•for partial surrenders from the division;

•as part of a transfer to another division or the Fixed Account; and

•to pay contract charges and fees.

Unit values are calculated each valuation date at the close of normal trading of the NYSE. To calculate the unit value of a division, the unit value from the previous valuation date is multiplied by the division’s net investment factor for the current valuation period. The number of units does not change due to a change in unit value.

The net investment factor measures the performance of each division. The net investment factor for a valuation period is [(a) plus (b) divided by (c)] minus d where:

a = the share price (net asset value) of the underlying mutual fund at the end of the valuation period;

b = the per share amount of any dividend* (or other distribution) made by the mutual fund during the valuation period;

c = the share price (net asset value) of the underlying mutual fund at the end of the previous valuation period; and

d = the total Separate Account annual expenses.

* When an investment owned by an underlying mutual fund pays a dividend, the dividend increases the net asset value of a share of the underlying mutual fund as of the date the dividend is recorded. As the net asset value of a share of an underlying mutual fund increases, the unit value of the corresponding division also reflects an increase. Payment of a dividend under these circumstances does not increase the number of units you own in the division.

The Separate Account charges are calculated by dividing the annual amount of the charge by 365 and multiplying by the number of days in the valuation period.

17

Purchase Payments

• On your application, you direct how your purchase payments will be allocated to the Investment Options.

• Allocations may be in percentages.

• Percentages must be in whole numbers and total 100%.

• Subsequent purchase payments are allocated according to your future purchase payment allocation instructions.

• Changes to the allocation instructions are made without charge.

•A change is effective on the next valuation period after we receive your new instructions.

•You can change the current allocations and future allocation instructions by:

•mailing your instructions to us;

•calling us at 1-800-852-4450 (if telephone privileges apply);

•faxing your instructions to us at 1-866-894-2087; or

•visiting www.principal.com.

• Changes to purchase payment allocations do not automatically result in the transfer of any existing investment option accumulated values. You must provide specific instructions to transfer existing accumulated values.

• Purchase payments are credited on the basis of unit value next determined after we receive a purchase payment.

• If no purchase payments are made during two consecutive calendar years and the accumulated value is less than $2,000, we reserve the right to terminate the Contract (see GENERAL INFORMATION – Reservation of Rights).

Division Transfers

•You may request an unscheduled transfer or set up a scheduled transfer by:

•mailing your instructions to us;

•calling us at 1-800-852-4450 (if telephone privileges apply);

•faxing your instructions to us at 1-866-894-2087; or

•visiting www.principal.com.

•You must specify the dollar amount or percentage to transfer from each division.

•The minimum amount is the lesser of $100 or the value of your division.

• In states where allowed, we reserve the right to reject transfer instructions from someone providing them for multiple Contracts for which he or she is not the owner.

You may not make a transfer to the Fixed Account if:

•a transfer has been made from the Fixed Account to a division within six months; or

• following the transfer, the Fixed Account value would be greater than $1,000,000 (without our prior approval).

Unscheduled Transfers

• You may make unscheduled division transfers from one division to another division or to the Fixed Account by:

•mailing your instructions to us;

•calling us at 1-800-852-4450 (if telephone privileges apply);

•faxing your instructions to us at 1-866-894-2087; or

•visiting www.principal.com.

• Transfers are not permitted into DCA Plus Accounts.

• The transfer is made, and values determined, as of the end of the valuation period in which we receive your request.

• We reserve the right to impose a fee of the lesser of $30 or 2% of each unscheduled transfer after the first unscheduled transfer in a contract year.

Limitations on Unscheduled Transfers. We reserve the right to reject excessive exchanges or purchases if the trade would disrupt the management of the Separate Account, any division of the Separate Account or any underlying mutual fund. In addition, we may suspend or modify transfer privileges in our sole discretion at any time to prevent market timing efforts that could disadvantage other owners. These modifications could include, but not be limited to:

• requiring a minimum time period between each transfer;

• imposing a transfer fee;

• limiting the dollar amount that an owner may transfer at any one time; or

• not accepting transfer requests from someone providing requests for multiple Contracts for which he or she is not the owner.

18

Scheduled Transfers (Dollar Cost Averaging)

• You may elect to have transfers made on a scheduled basis.

• There is no charge for scheduled transfers and no charge for participating in the scheduled transfer program.

• You must specify the dollar amount of the transfer.

• You select the transfer date (other than the 29th, 30th or 31st) and the transfer period (monthly, quarterly, semi-annually or annually).

• If the selected date is not a valuation date, the transfer is completed on the next valuation date.

• Transfers are not permitted into DCA Plus Accounts.

• If you want to stop a scheduled transfer, then you must provide us notice prior to the date of the scheduled transfer.

• Transfers continue until your value in the division is zero or we receive notice to stop them.

• We reserve the right to limit the number of divisions from which simultaneous transfers are made. In no event will it ever be less than two.

Scheduled transfers are designed to reduce the risks that result from market fluctuations. They do this by spreading out the allocation of your purchase payments to investment options over a longer period of time. This allows you to reduce the risk of investing most of your purchase payments at a time when market prices are high. The results of this strategy depend on market trends and are not guaranteed.

Example:

Month	Amount Invested	Share Price	Shares Purchased
January	$100	$25.00	4
February	$100	$20.00	5
March	$100	$20.00	5
April	$100	$10.00	10
May	$100	$25.00	4
June	$100	$20.00	5
Total	$600	$120.00	33

In the example above, the average share price is $20.00 (total of share prices ($120.00) divided by number of purchases (6)). The average share cost is $18.18 (amount invested ($600.00) divided by number of shares purchased (33)).

Automatic Portfolio Rebalancing (APR)

• APR allows you to maintain a specific percentage of your Separate Account accumulated value in specified divisions over time.

• You may elect APR at any time.

• APR is not available for values in the Fixed Account or the DCA Plus Accounts.

• APR is not available if you have arranged scheduled transfers from the same division.

• APR will not begin until the examination period has expired.

• There is no charge for APR transfers.

• APR can be done on the frequency you specify:

•quarterly (on a calendar year or contract year basis); or

•semi-annually or annually (on a contract year basis).

• You may rebalance by:

•mailing your instructions to us,

•calling us at 1-800-852-4450 (if telephone privileges apply);

•faxing your instructions to us at 1-866-894-2087; or

•visiting www.principal.com.

Divisions are rebalanced at the end of the valuation period during which we receive your request.

Example: You elect APR to maintain your Separate Account accumulated value with 50% in the Equity Income Division and 50% in the Real Estate Securities Division. At the end of the specified period, 60% of the values accumulated value is in the Equity Income Division, with the remaining 40% in the Real Estate Securities Division. By rebalancing, units from the Equity Income Division are sold and applied to the Real Estate Securities Division so that 50% of the Separate Account accumulated value is once again in each Division.

19

Telephone and Internet Services

If you elect telephone services or you elect internet services and satisfy our internet service requirements (which are designed to ensure compliance with federal UETA and E-SIGN laws), instructions for the following transactions may be given to us via the telephone or internet:

•make purchase payment allocation changes;

•set up Dollar Cost Averaging (DCA) scheduled transfers;

•make transfers; and

•make changes to APR.

Neither the Company nor the Separate Account is responsible for the authenticity of telephone service or internet transaction requests. We reserve the right to refuse telephone service or internet transaction requests. You are liable for a loss resulting from a fraudulent telephone or internet order that we reasonably believe is genuine. We follow procedures in an attempt to assure genuine telephone service or internet transactions. If these procedures are not followed, we may be liable for loss caused by unauthorized or fraudulent transactions. The procedures may include recording telephone service transactions, requesting personal identification (name, address, security phrase, password, daytime telephone number, social security number and/or birth date) and sending written confirmation to your address of record.

Instructions received via our telephone services and/or the internet are binding on both owners if the Contract is jointly owned.

If the Contract is owned by a business entity or a trust, an authorized individual (with the proper password) may use telephone and/or internet services. Instructions provided by the authorized individual are binding on the owner.

We reserve the right to modify or terminate telephone service or internet transaction procedures at any time. Whenever reasonably feasible, we will provide you with prior notice if we modify or terminate telephone service or internet services. In some instances, it may not be reasonably feasible to provide prior notice if we modify or terminate telephone service or internet transaction procedures; however, any modification or termination will apply to all Contract owners in a non-discriminatory fashion.

Telephone Services

Telephone services are available to you. Telephone services may be declined on the application or at any later date by providing us with written notice. You may also elect telephone authorization for your registered representative by providing us written notice.

If you elect telephone privileges, instructions

• may be given by calling us at 1-800-852-4450 while we are open for business (generally, between 8 a.m. and 5 p.m. Eastern Time on any day that the NYSE is open).

• are effective the day they are received if we receive the instructions in good order before the close of normal trading of the NYSE (generally 4:00 p.m. Eastern Time).

• are effective the next valuation day if we receive the instructions when we are not open for business and/or after the NYSE closes its normal trading.

Internet

Internet services are available to you if you register for a secure login on the Principal Financial Group web site, www.principal.com. You may also elect internet authorization for your registered representative by providing us written notice.

If you register for internet privileges, instructions

• are effective the day they are received if we receive the instructions in good order before the close of normal trading of the NYSE (generally 4:00 p.m. Eastern Time).

• are effective the next valuation day if we receive the instructions when we are not open for business and/or after the NYSE closes its normal trading.

20

Surrenders

You may surrender your Contract by providing us notice. Surrenders result in the redemption of units and your receipt of the value of the redeemed units minus any applicable fees and surrender charges. The values are determined as of the end of the valuation period in which we receive your request. Surrenders from the Separate Account are generally paid within seven days of the effective date of the request for surrender (or earlier if required by law). However, certain delays in payment are permitted (see Delay of Payments). Surrenders before age 59 ½ may involve an income tax penalty (see FEDERAL TAX MATTERS).

You may specify surrender allocation percentages with each partial surrender request. If you don’t provide us with specific percentages, we will use your purchase payment allocation percentages for the partial surrender. Surrenders may be subject to a surrender charge (see Surrender Charge).

Surrender requests may be sent to us at:

Principal Life Insurance Company

P O Box 9382

Des Moines, Iowa 50306-9382

Total Surrender

• You may surrender the Contract at any time before the annuitization date.

• You receive the cash surrender value at the end of the valuation period during which we receive your surrender request.

• The cash surrender value is your accumulated value minus any applicable surrender charges and fee(s) (contract fee and or prorated share of the charge(s) for optional rider(s)).

• The written consent of all collateral assignees and irrevocable beneficiaries must be obtained prior to surrender. A collateral assignment is an agreement under which you assign the annuity benefits to a lender as collateral for a loan. An irrevocable beneficiary is someone whose name cannot be removed from this annuity contract without his or her consent.

• We reserve the right to require you to return the Contract.

Unscheduled Partial Surrender

• Prior to the annuitization date and during the lifetime of the Annuitant, you may surrender a portion of your accumulated value by sending us a written request.

• You must specify the dollar amount of the surrender (which must be at least $100).

• The unscheduled partial surrender is effective at the end of the unscheduled partial valuation period during which we receive your written request for the unscheduled partial surrender.

• The unscheduled partial surrender is deducted from your Investment Options according to the surrender allocation percentages you specify.

• If surrender allocation percentages are not specified, we use your purchase payment allocation percentages.

• We surrender units from your investment options to equal the dollar amount of the unscheduled partial surrender request plus any applicable surrender charge and fee.

• The accumulated value after the unscheduled partial surrender must be equal to or greater than $5,000 (we reserve the right to change the minimum remaining accumulated value but it will not be greater than $10,000).

Scheduled Partial Surrender

• You may elect scheduled partial surrenders from any of the investment options on a scheduled basis by sending us written notice.

• Your accumulated value must be at least $5,000 when the scheduled partial surrenders begin.

• You may specify monthly, quarterly, semi-annually or annually and choose a surrender date (other than the 29th, 30th or 31st).

• If the selected date is not a valuation date, the scheduled partial surrender is completed on the next valuation date.

• All scheduled partial surrenders occurring on the Contract anniversary are reflected in the values for the prior year.

• We surrender units from your investment options to equal the dollar amount of the scheduled partial surrender request plus any applicable surrender charge.

• The scheduled partial surrenders continue until your value in the division is zero or we receive written notice to stop the scheduled partial surrenders.

Death Benefit

The following table illustrates the various situations and the resulting death benefit payment if you die before the annuitization date.

If you die and . . .	And . . .	Then . . .
You are the sole owner	Your spouse is not named as a primary beneficiary	The beneficiary(ies) receives the death benefit under the Contract. If a beneficiary dies before you, on your death we will make equal payments to the surviving beneficiaries unless you provided us with other written instructions. If no beneficiary(ies) survives you, the death benefit is paid to your estate in a single payment. Upon your death, only your beneficiary(ies’) right to the death benefit will continue; all other rights and benefits under the Contract will terminate.
You are the sole owner	Your spouse is named as a primary beneficiary	Your spouse may either a. elect to continue the Contract; or b. receive the death benefit under the Contract. All other beneficiaries receive the death benefit under the Contract. If a beneficiary dies before you, on your death we will make equal payments to the surviving beneficiaries unless you provided us with other written instructions. If no beneficiary(ies) survives you, the death benefit is paid to your estate in a single payment. Unless your spouse elects to continue the Contract, only your spouse’s and any other beneficiary(ies’) right to the death benefit will continue; all other rights and benefits under the Contract will terminate.
You are a joint owner	The surviving joint owner is not your spouse	The surviving owner receives the death benefit under the Contract. Upon your death, only the surviving owner’s right to the death benefit will continue; all other rights and benefits under the Contract will terminate.
You are a joint owner	The surviving joint owner is your spouse	Your spouse may either a. elect to continue the Contract; or b. receive the death benefit under the Contract. Unless the surviving spouse owner elects to continue the Contract, upon your death, only your spouse’s right to the death benefit will continue; all other rights and benefits under the rider and the Contract will terminate.

22

If . . .	And . . .	Then . . .
The annuitant dies	The owner is not a natural person	The beneficiary(ies) receives the death benefit under the Contract. If a beneficiary dies before the annuitant, on the annuitant’s death we will make equal payments to the surviving beneficiaries unless the owner provided us with other written instructions. If no beneficiary(ies) survives the annuitant, the death benefit is paid to the owner. Upon the annuitant’s death, only the beneficiary(ies’) right to the death benefit will continue; all other rights and benefits under the Contract will terminate.

Before the annuitization date, you may give us written instructions for payment under a death benefit option. If we do not receive your instructions, the death benefit is paid according to instructions from the beneficiary(ies). The beneficiary(ies) may elect to apply the death benefit under an annuity benefit payment option or receive the death benefit as a single payment. Generally, unless the beneficiary(ies) elects otherwise, we pay the death benefit in a single payment, subject to proof of your death.

No surrender charge applies when a death benefit is paid.

Standard Death Benefit – for Contracts issued prior to November 23, 2003 (and all contracts issued in Louisiana, Oregon, and South Carolina)

The amount of the standard death benefit is the greatest of a, b or c, where:

a = the accumulated value on the date we receive proof of death and all required documents;

b = the total of purchase payments minus any partial surrenders (and any applicable fees and surrender charges) made prior to the date we receive proof of death and all required documents; and

c = the highest accumulated value on any contract anniversary that is wholly divisible by seven (for example, contract anniversaries 7, 14, 21, 28, etc.) plus any purchase payments since that contract anniversary and minus any partial surrenders (and any applicable surrender charges and fees) made after that contract anniversary.

Standard Death Benefit - for Contracts issued on or after November 23, 2003 (except contracts issued in Louisiana, Oregon, and South Carolina)

The amount of the standard death benefit is the greatest of a, b or c, where:

a = the accumulated value on the date we receive proof of death and all required documents;

b = is the total of purchase payments minus an adjustment* for each partial surrender (and any applicable fees and surrender charges) made prior to the date we receive proof of death and all required documents; and

c = is the highest accumulated value on any contract anniversary that is wholly divisible by seven (for example, contract anniversaries 7, 14, 21, 28, etc.) plus any purchase payments since that contract anniversary and minus an adjustment* for each partial surrender (and any applicable fees and surrender charges) made after that contract anniversary.

* The adjustment for each partial surrender is equal to ((i) divided by (ii)) multiplied by the amounts determined in (b) or (c) above immediately prior to the partial surrender, where:

•(i)    is the amount of the partial surrender (and any applicable fees and surrender charges); and

•(ii)    is the accumulated value immediately before the partial surrender.

Annual Enhanced Death Benefit Rider

This is an optional death benefit rider. The rider provides you with the greater of the annual enhanced death benefit or the standard death benefit. The rider can only be purchased at the time the Contract is issued. Once the rider is terminated, it cannot be reinstated (except in Florida). The rider charge is discussed in the section CHARGES AND DEDUCTIONS — Charges for Optional Riders.

23

For Contracts issued prior to November 23, 2003 and all contracts issued in New Jersey and Washington

Prior to the annuitization date and prior to the lock-in date (the later of five years after the rider effective date or the contract anniversary following the original owner’s or original annuitant’s 75th birthday), the annual enhanced death benefit is the greatest of (a) or (b) or (c) where:

• (a) is the standard death benefit;

• (b) is the annual increasing death benefit, based on purchase payments (accumulated at 5% annually) minus any partial surrender (and any applicable fees and charges) (accumulated at 5% annually) until the lock-in date; or

• (c) is the highest accumulated value on any prior contract anniversary, plus purchase payments and minus the amount of each partial surrender (and any applicable fees and charges) made after that contract anniversary and prior to the lock-in date.

NOTE: For Contracts issued in New York prior to November 23, 2003, the annual enhanced death benefit is the greater of (a) or (c).

Lock-in Feature -  At the later of five years after the rider effective date or the contract anniversary following the original owner’s or original annuitant’s 75th birthday (the “lock-in date”), the death benefit amount is locked-in. After the lock-in date, the death benefit increases by purchase payments (subject to applicable restrictions) made after the lock-in date and decreases by the amount of each partial surrender (and any applicable fees and surrender charges) made after the lock-in date. After the lock-in date, once the standard death benefit equals the annual enhanced death benefit, the annual enhanced death benefit and any associated charges terminate. The standard death benefit then applies.

For Contracts issued on or after November 23, 2003 (except for contracts issued in New Jersey and Washington)

Prior to the annuitization date and prior to the lock-in date (the later of five years after the rider effective date or the contract anniversary following the original owner’s or original annuitant’s 75th birthday), the annual enhanced death benefit is the greatest of (a) or (b) or (c) where:

• (a) is the standard death benefit;

• (b) is the annual increasing death benefit, based on purchase payments (accumulated at 5% annually) minus the proportionate withdrawal amount* of each partial surrender (and any applicable fees and surrender charges) (accumulated at 5% annually) until the lock-in date; or

• (c) is the highest accumulated value on any prior contract anniversary, plus purchase payments and minus the proportionate withdrawal amount* of each partial surrender (and any applicable fees and surrender charges) made after that contract anniversary and prior to the lock-in date.

NOTE: For Contracts issued in New York on or after November 23, 2003, the annual enhanced death benefit is the greater of (a) or (c).

* The proportionate withdrawal amount is equal to ((i) divided by (ii)) multiplied by the amounts determined in (b) or (c) above immediately prior to the partial surrender, where:

(i)    is the amount of the partial surrender (and any applicable fees and surrender charges); and

(ii)    is the accumulated value immediately before the partial surrender.

Lock-In Feature - At the later of five years after the rider effective date or the contract anniversary following the original owner’s or original annuitant’s 75th birthday (the “lock-in date”), the death benefit amount is locked-in. After the lock-in date, the death benefit increases by purchase payments (subject to applicable restrictions) made after the lock-in date and decreases by the adjusted proportionate withdrawal amount of each partial surrender (and any applicable fees and surrender charges). After the lock-in date, once the standard death benefit equals the annual enhanced death benefit, the annual enhanced death benefit and any associated charge terminate. The standard death benefit then applies.

Payment of Death Benefit

The death benefit is usually paid within five business days of our receiving all documents (including proof of death) that we require to process the claim. Payment is made according to benefit instructions provided by you. Some states require this payment to be made in less than five business days. Under certain circumstances, this payment may be delayed (see Delay of Payments). We pay interest (as required by state law) on the death benefit from the date we receive all required documents until payment is made or until the death benefit is applied under an annuity benefit payment option.

NOTE: Proof of death includes: a certified copy of a death certificate; a certified copy of a court order; a written statement by a medical doctor; or other proof satisfactory to us.

24

The accumulated value remains invested in the divisions until the valuation period during which we receive the required documents. If more than one beneficiary is named, each beneficiary’s portion of the death benefit remains invested in the divisions until the valuation period during which we receive the required documents for that beneficiary. After payment of all of the death benefit, the Contract is terminated.

The Annuity Benefit Payment Period

Annuitization Date

You may specify an annuitization date in your application. You may change the annuitization date with our prior approval. The request must be in writing. You may not select an annuitization date later than the maximum annuitization date found on the data page. If you do not specify an annuitization date, the annuitization date is the maximum annuitization date shown on the data page.

You may annuitize your Contract at any time by electing to receive payments under an annuity benefit payment option. If the accumulated value on the annuitization date is less than $2,000.00 or if the amount applied under an annuity benefit payment option is less than the minimum requirement, we may pay out the entire amount in a single payment. The contract would then be canceled. You may select when you want the annuity benefit payments to begin (within the period that begins the business day following our receipt of your instruction and ends one year after our receipt of your instructions).

Once annuity benefit payments begin under the annuity benefit payment option you choose, the option may not be changed. In addition, once annuity benefit payments begin, you may not surrender or otherwise liquidate or commute any of your accumulated value that has been annuitized.

Depending on the type of annuity benefit payment option selected, annuity benefit payments that are initiated either before or after the annuitization date may be subject to penalty taxes (see FEDERAL TAX MATTERS). You should consider this carefully when you select or change the annuity benefit payment commencement date.

Annuity Benefit Payment Options

We offer fixed annuity benefit payments only. No surrender charge is imposed on any portion of your accumulated value that has been annuitized.

You may choose from several fixed annuity benefit payment options. Annuity benefit payments will be made on the frequency you choose. You may elect to have your annuity benefit payments made on a monthly, quarterly, semiannual or annual basis. The dollar amount of the annuity benefit payments is specified for the entire payment period according to the annuity benefit payment option selected. There is no right to take a total surrender after the annuitization date.

The amount of the fixed annuity benefit payment depends on:

• the amount of accumulated value applied to the annuity benefit payment option;

• the annuity benefit payment option selected; and

• the age and gender of the annuitant and joint annuitant, if any (unless the Fixed Period Income benefit payment option is selected).

Annuity benefit payments are determined in accordance with annuity tables and other provisions contained in the Contract. The annuity benefit payments tables contained in this Contract are based on the 1983 Table A Mortality Table. These tables are guaranteed for the life of the Contract. The amount of the initial annuity benefit payment is determined by applying the accumulated value as of the date of the application to the annuity table for the annuitant’s annuity option, gender, and age.

Annuity benefit payments generally are higher for male annuitants than for female annuitants with an otherwise identical Contract. This is because statistically females have longer life expectancies than males. In certain states, this difference may not be taken into consideration in fixing the annuity benefit payment amount. Additionally, Contracts with no gender distinctions are made available for certain employer-sponsored plans because, under most such plans, gender discrimination is prohibited by law.

You may select an annuity benefit payment option by written request only. Your selection of an annuity benefit payment option may not be changed after annuity benefit payments begin. You may change your selection of an annuity benefit payment option (for which no annuity benefit payments have been made) by sending us a written request prior to the annuitization date. We must receive your written request on or before the annuitization date. If you fail to elect an annuity benefit payment option, we will automatically apply:

• for Contracts with one annuitant – Life Income with annuity benefit payments guaranteed for a period of 10 years.

• for Contracts with joint annuitants – Joint and Full Survivor Life Income with annuity benefit payments guaranteed for a period of 10 years.

25

The available annuity benefit payment options include:

• Fixed Period Income - Level payments are made for a fixed period. You may select a range from 5 to 30 years (state variations may apply). If the annuitant dies before the selected period expires, payments continue to you or the person(s) you designate until the end of the period. If a shorter period is required by law, we will pay a commuted value at the end of that shorter period. Payments stop after all guaranteed payments are made.

• Life Income - Level payments are made during the annuitant’s lifetime only. NOTE:There is no death benefit value remaining or further payments when the annuitant dies. If you defer the first payment date, it is possible that you would receive no payments if the annuitant dies before the first payment date.

• Life Income with Period Certain - Level payments continue during the annuitant’s lifetime with a guaranteed payment period of 5 to 30 years. If the annuitant dies before all of the guaranteed payments have been made, the guaranteed payments continue to you or the person(s) you designate until the end of the guaranteed payment period. If a shorter period is required by law, we will pay a commuted value at the end of that shorter period.

• Joint and Survivor -Payments continue as long as either the annuitant or the joint annuitant is alive. You may also choose an option that lowers the amount of income after the death of a joint annuitant. It is possible that you would only receive one payment under this option if both annuitants die before the second payment is due. If you defer the first payment date, it is possible that you would receive no payments if both annuitants die before the first payment date. NOTE:There is no death benefit value remaining or future payments after both annuitants have died.

• Joint and Survivor with Period Certain - Payments continue as long as either the annuitant or the joint annuitant is alive with a guaranteed payment period of 5 to 30 years. You may choose an option that lowers the amount of income after the death of a joint annuitant. If both annuitants die before all guaranteed payments have been made, the guaranteed payments continue to you or the person(s) you designate until the end of the guaranteed payment period. If a shorter period is required by law, we will pay a commuted value at the end of that shorter period.

• Joint and Two-thirds Survivor Life Income -Payments continue as long as either the annuitant or the joint annuitant is alive. If either the annuitant or joint annuitant dies, payments continue to the survivor at two-thirds the original amount. Payments stop when both the annuitant and joint annuitant have died. It is possible that only one payment is made under this option if both annuitants die before the second payment is due. If you defer the first payment date, it is possible that you would receive no payments if both annuitants die before the first payment date. NOTE:There is no death benefit value remaining or future payments after both annuitants have died.

Other annuity benefit payment options may be available.

Supplementary Contract

When you annuitize your Contract’s accumulated value, we issue a supplementary fixed annuity contract that provides an annuity benefit payment based on the amount you have annuitized and the annuity benefit payment option that you have selected. The date of the first annuity benefit payment under the supplementary contract is the effective date of that supplementary contract unless you select a date for the first annuity benefit payment that is later than the supplementary contract effective date. The first annuity benefit payment must be made within one year of the supplementary contract effective date.

Tax Considerations Regarding Annuity Benefit Payment Options

If you own one or more tax qualified annuity contracts, you may avoid tax penalties if payments from at least one of your tax qualified contracts begin no later than April 1 following the calendar year in which you turn age 72. The required minimum distribution payment must be in equal (or substantially equal) amounts over your life or over the joint lives of you and your designated beneficiary. These required minimum distribution payments must be made at least once a year. Tax penalties may apply at your death on certain excess accumulations. You should confer with your tax advisor about any potential tax penalties before you select an annuity benefit payment option or take other distributions from the Contract.

Additional rules apply to distributions under non-qualified contracts (see RequiredDistributions for Non-Qualified Contracts).

Death of Annuitant (during the annuity benefit payment period)

If the annuitant dies during the annuity benefit payment period, remaining annuity benefit payments are made to the owner throughout the guarantee period, if any, or for the life of any joint annuitant, if any. If the owner is the annuitant, remaining annuity benefit payments are made to the joint owner, if any, or the named beneficiaries. In all cases the person entitled to receive payments also receives any rights and privileges under the annuity benefit payment option.

26

CHARGES AND DEDUCTIONS

Certain charges are deducted under the Contract. If the charge is not sufficient to cover our costs, we bear the loss. If the benefit is more than our costs, the excess is profit to the Company. Other than the Annual Fee and Premium Taxes (which we do not expect to generate a profit), we expect a profit from the fees and charges listed below.

In addition to the charges under the Contract, there are also deductions from and expenses paid out of the assets of the underlying mutual funds which are described in the underlying mutual funds’ prospectuses.

Annual Fee

Contracts with an accumulated value of less than $30,000 are subject to an annual Contract fee of the lesser of $30 or 2% of the accumulated value. Currently, we do not charge the annual fee if your accumulated value is $30,000 or more. If you own more than one variable annuity contract with us, all the Contracts you own or jointly own are aggregated, on each Contract’s anniversary, to determine if the $30,000 minimum has been met and whether that Contract will be charged. The fee is deducted from the investment option that has the greatest value. The fee is deducted on each Contract anniversary and upon total surrender of the Contract. The fee assists in covering administration costs, primarily costs to establish and maintain the records which relate to the Contract.

Mortality and Expense Risks Charge

We assess each division with a daily charge for mortality and expense risks. The annual rate of the charge is 1.25% of the average daily net assets of the Separate Account. We agree not to increase this charge for the duration of the Contract. This charge is assessed only prior to the annuitization date. This charge is assessed daily when the value of a unit is calculated.

We have a mortality risk in that we guarantee payment of a death benefit in a single payment or under an annuity benefit payment option. No surrender charge is imposed on a death benefit payment which gives us an additional mortality risk.

The expense risk that we assume is that the actual expenses incurred in issuing and administering the Contract exceed the Contract limits on administrative charges.

If the mortality and expense risks charge is not enough to cover the costs, we bear the loss. If the amount of mortality and expense risks charge deducted is more than our costs, the excess is profit to the Company.

Separate Administration Charge

We assess each division with a daily Separate Account administration charge. The annual rate of the charge is 0.05% of the average daily net assets of the Separate Account divisions. This charge only is assessed prior to the annuitization date. This charge is assessed daily, at the time the value of a unit is calculated. We reserve the right to increase this administration charge up to an annual rate of 0.15% of the average daily net assets of the Separate Account divisions.

The administration charge is intended to cover our costs for administration of the Contract that are not covered in the mortality and expense risks charge above. If the administration charge is not enough to cover our costs, we bear the loss. If the administration charge is more than our costs, the excess is profit to the Company.

Charges for Optional Riders

Subject to certain conditions, you may add one or more of the following optional riders to your Contract. Detailed information concerning the optional riders may be obtained from your registered representative or by calling us at 1-800-852-4450.

Purchase Payment Credit Rider. The current annual charge for the rider is 0.60% of the average daily net assets of the Separate Account divisions. If you elect the Purchase Payment Credit Rider, the rider charge is assessed until completion of your 8th contract year (and only prior to the annuitization date) even if the credit(s) have been recovered. After the 8th Contract anniversary, your Contract accumulated value is moved to units in your chosen divisions that do not include this rider charge. This move of division units will not affect your accumulated value. It will, however, result in a smaller number of division units but those units will have a higher unit value. We will notify you when the division units move because of discontinuation of the rider charge.

The rider charge is intended to cover our cost for the credit(s).

27

Annual Enhanced Death Benefit Rider

The annual charge for the rider is 0.20% of the accumulated value (0.15% in New York). The charge is equal to 0.05% (0.0375% in New York) of the average accumulated value during the calendar quarter. The charge is deducted through the redemption of units from the accumulated value in the same proportion as the surrender allocation percentages. If the rider is purchased after the beginning of a quarter, the charge is prorated according to the number of days it is in effect during the quarter. Upon termination of the rider or upon death, you will be charged based on the number of days the rider is in effect during the quarter.

The rider charge is intended to reimburse us for the cost of the potentially greater death benefit provided by this rider.

Transaction Fee

We reserve the right to charge a transaction fee of the lesser of $25 or 2% of each unscheduled partial surrender after the 12th unscheduled partial surrender in a contract year. The transaction fee would be deducted from the accumulated value remaining in the investment option(s) from which the amount is surrendered, on a pro rata basis.

We also reserve the right to charge a transaction fee of the lesser of $30 or 2% of each unscheduled transfer after the first unscheduled transfer in a contract year. The transfer fee would be deducted from the investment option(s) from which the amount is transferred, on a pro rata basis.

Premium Taxes

We reserve the right to deduct an amount to cover any premium taxes imposed by states or other jurisdictions. Any deduction is made from either a purchase payment when we receive it, or from the accumulated value when you request a surrender or you request application of the accumulated value under an annuity benefit payment option. Premium taxes range from 0% in most states to as high as 3.50%.

Surrender Charge

No sales charge is collected or deducted when purchase payments are applied under the Contract. A surrender charge is assessed on certain total or partial surrenders. The amounts we receive from the surrender charge are used to cover some of the expenses of the sale of the Contract (commissions and other promotional or distribution expenses). If the surrender charge collected is not enough to cover the actual costs of distribution, the costs are paid from the Company’s General Account assets which includes profit, if any, from the mortality and expense risks charge.

The surrender charge for any total or partial surrender is a percentage of the purchase payments surrendered which were received by us during the contract years prior to the surrender. The applicable percentage which is applied to the sum of the purchase payments paid during each contract year is determined by the following tables. The amount of the purchase payment credit, if any, is not included in the sum of the purchase payments made.

Surrender Charge without the Purchase Payment Credit Rider (as a percentage of amounts surrendered)

Number of completed contract years since each purchase payment was made	Surrender charge applied to all purchase payments received in that contract year
0 (year of purchase payment)*	6%
1	6%
2	6%
3	5%
4	4%
5	3%
6	2%
7 and later	0%

28

Surrender Charge with the Purchase Payment Credit Rider (as a percentage of amounts surrendered)

Number of completed contract years since each purchase payment was made	Surrender charge applied to all purchase payments received in that contract year
0 (year of purchase payment)*	8%
1	8%
2	8%
3	8%
4	7%
5	6%
6	5%
7	4%
8	3%
9 and later	0%

* Each purchase payment begins in year 0 for purposes of calculating the percentage applied to that purchase payment. However, purchase payments are added together by contract year for purposes of determining the applicable surrender charge. If your contract year begins April 1 and ends March 31 the following year, then all purchase payments received during that period are considered to have been made in that contract year.

For purposes of calculating surrender charges, we assume that surrenders and transfers are made in the following order:

• first from purchase payments no longer subject to a surrender charge;

• then from the free surrender privilege (first from the earnings, then from the oldest purchase payments (first-in, first-out)) described below; and

• then from purchase payments subject to a surrender charge on a first-in, first-out basis.

A surrender charge is not imposed in states where it is prohibited, including:

• New Jersey – no surrender charge for total surrender on or after the later of the annuitant’s 64th birthday or 4 years after the contract date.

• Washington – no surrender charge for total surrender on or after the later of the annuitant’s 70th birthday or 10 years after the contract date.

NOTE: Partial surrenders may be subject to both the surrender charge and the transaction fee, if any.

Free Surrender Privilege

The free surrender privilege is an amount normally subject to a surrender charge that may be surrendered without a charge. The free surrender privilege is the greater of:

• earnings in the Contract (earnings = accumulated value less unsurrendered purchase payments as of the surrender date); or

• 10% of the purchase payments, decreased by any partial surrenders since the last contract anniversary.

Any amount not taken under the free surrender privilege in a contract year is not added to the amount available under the free surrender privilege for any following contract year(s).

Unscheduled partial surrenders of the free surrender privilege may be subject to the transaction fee described above.

Waiver of Surrender Charge

The surrender charge does not apply to:

• amounts applied under an annuity benefit payment option; or

• payment of any death benefit, however, the surrender charge does apply to purchase payments made by a surviving spouse after an owner’s death; or

• amounts distributed to satisfy the minimum distribution requirement of Section 401(a)9 of the Internal Revenue Code provided that the amount surrendered does not exceed the minimum distribution amount which would have been calculated based on the value of this Contract alone; or

• an amount transferred from a Contract used to fund an IRA to another annuity contract issued by the Company to fund an IRA of the participant’s spouse when the distribution is made pursuant to a divorce decree.

29

Waiver of Surrender Charge Rider

This Waiver of Surrender Charge Rider waives the surrender charge on surrenders made after the first contract anniversary if the original owner or original annuitant has a critical need. This rider is automatically made a part of the Contract at issue. There is no charge for this rider. This rider may not be available in all states or through all broker dealers and may be subject to additional restrictions. Some rider provisions may vary from state to state. We may withdraw or prospectively restrict the availability of this rider at any time. For more information regarding availability or features of this rider, you may contact your registered representative or call us at 1-800-852-4450.

Waiver of the surrender charge is available for critical need if the following conditions are met:

• the original owner or original annuitant has a critical need (NOTE: A change of ownership will terminate this rider; once terminated the rider may not be reinstated); and

• the critical need did not exist before the contract date.

• For the purposes of this section, the following definitions apply:

• critical need – limited to an owner’s or annuitant’s confinement to a health care facility, terminal illness diagnosis or total and permanent disability. If the critical need is confinement to a health care facility, the confinement must continue for at least 60 consecutive days after the contract date and the surrender must occur within 90 days of the confinement’s end.

• health care facility – a licensed hospital or inpatient nursing facility providing daily medical treatment and keeping daily medical records for each patient (not primarily providing just residency or retirement care). This does not include a facility primarily providing drug or alcohol treatment, or a facility owned or operated by the owner, annuitant or a member of their immediate families.

• terminal illness – sickness or injury that results in the owner’s or annuitant’s life expectancy being 12 months or less from the date notice to receive a distribution from the Contract is received by the Company. In Texas and New Jersey, terminal illness is not included in the criteria for critical need.

• total and permanent disability – a disability that occurs after the contract date but before the original owner or annuitant reaches age 65 and qualifies to receive social security disability benefits. In New York, a different definition of total and permanent disability applies. In Oregon, total and permanent disability is not included in the criteria for critical need.

NOTE: The Waiver of Surrender Charge Rider is not available in Massachusetts.

Special Provisions for Group or Sponsored Arrangements

Where permitted by state law, Contracts may be purchased under group or sponsored arrangements as well as on an individual basis.

Group Arrangement – program under which a trustee, employer or similar entity purchases Contracts covering a group of individuals on a group basis.

Sponsored Arrangement – program under which an employer permits group solicitation of its employees or an association permits group solicitation of its members for the purchase of Contracts on an individual basis.

The charges and deductions described above may be reduced or eliminated for Contracts issued in connection with group or sponsored arrangements. The rules in effect at the time the application is approved will determine if reductions apply. Reductions may include but are not limited to sales of Contracts without, or with reduced, mortality and expense risks charges, annual fees or surrender charges.

Eligibility for and the amount of these reductions are determined by a number of factors, including the number of individuals in the group, the amount of expected purchase payments, total assets under management for the Contract owner, the relationship among the group’s members, the purpose for which the Contract is being purchased, the expected persistency of the Contract, and any other circumstances which, in our opinion are rationally related to the expected reduction in expenses. Reductions reflect the reduced sales efforts and administrative costs resulting from these arrangements. We may modify the criteria for and the amount of the reduction in the future. Modifications will not unfairly discriminate against any person, including affected Contract owners and other contract owners with contracts funded by the Separate Account.

Because of exemptive and exclusionary provisions, interests in the Fixed Account and DCA Plus Accounts are not registered under the Securities Act of 1933 and the General Account is not registered as an investment company under the Investment Company Act of 1940. The Fixed Account and DCA Plus Accounts are not subject to these Acts. The staff of the SEC does not review the prospectus disclosures relating to the Fixed Account or DCA Plus Accounts. However, these disclosures are subject to certain generally applicable provisions of the federal securities laws relating to the accuracy and completeness of statements made in the prospectus. Separate Account expenses are not assessed against any Fixed Account or DCA Plus Account values. More information concerning the Fixed Account and DCA Plus Accounts is available from your registered representative or by calling us at 1-800-852-4450.

Fixed Account

The Company guarantees that purchase payments allocated and amounts transferred to the Fixed Account earn interest at a guaranteed interest rate. In no event will the guaranteed interest rate be less than 3% compounded annually.

Each purchase payment allocated or amount transferred to the Fixed Account earns interest at the guaranteed rate in effect on the date it is received or transferred. This rate applies to each purchase payment or amount transferred through the end of the contract year.

Each contract anniversary, we declare a renewal interest rate that applies to the Fixed Account value in existence at that time. This rate applies until the end of the contract year. Interest is earned daily and compounded annually at the end of each contract year. Once credited, the interest is guaranteed and becomes part of the Fixed Account accumulated value from which deductions for fees and charges may be made.

Fixed Account Accumulated Value

Your Fixed Account accumulated value on any valuation date is equal to:

•purchase payments allocated to the Fixed Account;

•plus any transfers to the Fixed Account from the Separate Account and DCA Plus Accounts;

•plus interest credited to the Fixed Account;

•minus any surrenders or applicable surrender charges from the Fixed Account;

•minus any transfers to the Separate Account.

Fixed Account Transfers, Total and Partial Surrenders

Transfers and surrenders from the Fixed Account are subject to certain limitations. In addition, surrenders from the Fixed Account may be subject to a charge (see Surrender Charge).

You may transfer amounts from the Fixed Account to the divisions before the annuitization date and as provided below. The transfer is effective on the valuation date following our receiving your instructions. You may transfer amounts on either a scheduled or unscheduled basis by:

•mailing your instructions to us;

•calling us at 1-800-852-4450 (if telephone privileges apply);

•faxing your instructions to us at 1-866-894-2087; or

•visiting www.principal.com

You may not make both scheduled and unscheduled Fixed Account transfers in the same contract year.

Unscheduled Fixed Account Transfers

The minimum transfer amount is $100 (or entire Fixed Account accumulated value if less than $100). Once per contract year, within the 30 days following the contract anniversary date, you can:

• transfer an amount not to exceed 25% of your Fixed Account accumulated value; or

• transfer up to 100% of your Fixed Account accumulated value if:

•your Fixed Account accumulated value is less than $1,000; or

•(a) minus (b) is greater than 1% where:

•(a) is the weighted average of your Fixed Account interest rates for the preceding contract year; and

•(b) is the renewal interest rate for the Fixed Account.

We will inform you if the renewal interest rate falls to that level.

31

Scheduled Fixed Account Transfers (Fixed Account Dollar Cost Averaging)

You may make scheduled transfers on a monthly basis from the Fixed Account to the Separate Account as follows:

• Transfers occur on a date you specify (other than the 29th, 30th or 31st of any month).

• If the selected date is not a valuation date, the transfer is completed on the next valuation date.

• Scheduled transfers are only available if the Fixed Account accumulated value is $5,000 or more at the time the scheduled transfers begin.

• Scheduled monthly transfers of a specified dollar amount will continue until the Fixed Account accumulated value is zero or until you notify us to discontinue the transfers. This specified dollar amount cannot exceed 2% of your Fixed Account accumulated value.

• The minimum transfer amount is $100.

• If the Fixed Account accumulated value is less than $100 at the time of transfer, then the entire Fixed Account accumulated value will be transferred.

• If you stop the transfers, you may not start them again without our prior approval.

Dollar Cost Averaging Plus Program (DCA Plus Program)

Purchase payments allocated to the DCA Plus Accounts earn a guaranteed interest rate. A portion of your DCA Plus Account accumulated value is periodically transferred (on the 28th of each month) to divisions and/or to the Fixed Account. If the 28th is not a valuation date, then the transfer occurs on the next valuation date. The transfers are allocated according to your DCA Plus allocation instructions. Transfers into a DCA Plus Account are not permitted.

If you elect the Purchase Payment Credit rider, you may not participate in the DCA Plus Program.

DCA Plus Purchase Payments

You may enroll in the DCA Plus program by allocating a minimum purchase payment of $1,000 into a DCA Plus Account and selecting divisions and or the Fixed Account into which transfers will be made. Subsequent purchase payments of at least $1,000 are permitted. You can change your DCA Plus allocation instructions during the transfer period. Automatic portfolio rebalancing does not apply to DCA Plus Accounts.

DCA Plus purchase payments receive the fixed rate of return in effect on the date each purchase payment is received by us. The rate of return remains in effect for the remainder of the 6-month or 12-month DCA Plus transfer program.

Selecting a DCA Plus Account

DCA Plus Accounts are available in either a 6-month transfer program or a 12-month transfer program. The 6-month transfer program and the 12-month transfer program generally will have different credited interest rates. You may enroll in both a 6-month and 12-month DCA Plus program. However, you may only participate in one 6-month and one 12-month DCA Plus program at a time. Under the 6-month transfer program, all purchase payments and accrued interest must be transferred from the DCA Plus Account to the selected divisions and/or Fixed Account in no more than 6 months. Under the 12-month transfer program, all payments and accrued interest must be transferred to the selected divisions and or Fixed Account in no more than 12 months.

We will transfer an amount each month which is equal to your DCA Plus Account value divided by the number of months remaining in your transfer program. For example, if four scheduled transfers remain in the six-month transfer program and the DCA Plus Account accumulated value is $4,000, the transfer amount would be $1,000 ($4,000 / 4).

Scheduled DCA Plus Transfers

Transfers are made from DCA Plus Accounts to divisions and the Fixed Account according to your allocation instructions. The transfers begin after we receive your purchase payment and completed enrollment instructions. Transfers occur on the 28th of the month and continue until your entire DCA Plus Account accumulated value is transferred.

Unscheduled DCA Plus Transfers

You may make unscheduled transfers from DCA Plus Accounts to divisions and or the Fixed Account. A transfer is made, and values determined, as of the end of the valuation period in which we receive your request.

DCA Plus Surrenders

You may make scheduled or unscheduled surrenders from DCA Plus Accounts. Purchase payments earn interest according to the corresponding rate until the surrender date. Surrenders are subject to any applicable surrender charge.

32

GENERAL PROVISIONS

The Contract

The entire Contract is made up of the Contract, amendments, riders and endorsements and data page. Only our corporate officers can agree to change or waive any provisions of a Contract. Any change or waiver must be in writing and signed by an officer of the Company.

Delay of Payments

Surrendered amounts are generally disbursed within seven calendar days after we receive your instruction for a surrender in a form acceptable to us. This period may be shorter where required by law. However, payment of any amount upon total or partial surrender, death, annuitization of accumulated value or the transfer to or from a division may be deferred during any period when the right to sell mutual fund shares is suspended as permitted under provisions of the Investment Company Act of 1940 (as amended).

The right to sell shares may be suspended during any period when:

• trading on the NYSE is restricted as determined by the SEC or when the NYSE is closed for other than weekends and holidays; or

• an emergency exists, as determined by the SEC, as a result of which:

•disposal by a mutual fund of securities owned by it is not reasonably practicable;

•it is not reasonably practicable for a mutual fund to fairly determine the value of its net assets; or

•the SEC permits suspension for the protection of security holders.

If payments are delayed the transaction will be processed on the first valuation date following the expiration of the permitted delay unless we receive your written instructions to cancel your surrender, annuitization, or transfer. Your written instruction must be received in the home office prior to the expiration of the permitted delay. The transaction will be completed within seven business days.

In addition, we reserve the right to defer payment of that portion of your accumulated value that is attributable to a premium payment made by check for a reasonable period of time (not to exceed 15 business days) to allow the check to clear the banking system.

Misstatement of Age or Gender

If the age or, where applicable, gender of the annuitant has been misstated, we adjust the annuity benefit payment under your Contract to reflect the amount that would have been payable at the correct age and gender. If we make any overpayment because of incorrect information about age or gender, or any error or miscalculation, we deduct the overpayment from the next payment or payments due. Underpayments are added to the next payment.

Assignment

If your Contract is part of your qualified plan, IRA, SEP, or SIMPLE-IRA, you may not assign ownership.

You may assign ownership of your non-qualified Contract. Each assignment is subject to any payments made or action taken by the Company prior to our notification of the assignment. We assume no responsibility for the validity of any assignment. An assignment or pledge of a Contract may have adverse tax consequences.

An assignment must be made in writing and filed with us at the home office. The irrevocable beneficiary(ies), if any, must authorize any assignment in writing. Your rights, as well as those of the annuitant and beneficiary, are subject to any assignment on file with us. Any amount paid to an assignee is treated as a partial surrender and is paid in a single payment.

The Company may refuse any assignment or transfer at any time on a non-discriminatory basis and may refuse any assignment where it believes such assignment may cause the development of a trading market.

Change of Owner or Annuitant

If your Contract is part of your qualified plan, IRA, SEP, or SIMPLE-IRA you may not change either the owner or the annuitant.

You may change your non-qualified Contract ownership and/or annuitant designation at any time. Your request must be in writing and approved by us. After approval, the change is effective as of the date you signed the request for change. If ownership is changed, then the waiver of the surrender charge for surrenders made because of critical need of the owner is not available. We reserve the right to require that you send us the Contract so that we can record the change.

33

If an annuitant who is not an owner dies while the Contract is in force, a new annuitant may be named unless the owner is a corporation, trust or other entity.

Beneficiary

While this Contract is in force, you have the right to name or change a beneficiary. This may be done as part of the application process or by sending us a written request. Unless you have named an irrevocable beneficiary, you may change your beneficiary designation by sending us notice.

Contract Termination

We reserve the right to terminate the Contract and make a single payment (without imposing any charges) to you if your accumulated value at the end of the accumulation period is less than $2,000. Before the Contract is terminated, we will send you a notice to increase the accumulated value to $2,000 within 60 days. Termination of the Contract will not unfairly discriminate against any owner.

Reinstatement

Reinstatement is only available for full surrender of your Contract. You cannot reinstate a partial surrender or partial annuitization; if you return either of these amounts, they will be considered new premium payments.

If you have requested to replace this Contract with an annuity contract from another company and want to reinstate this Contract, the following apply:

• we reinstate the Contract effective on the original surrender date;

• if you had the Purchase Payment Credit Rider on the original Contract, the 9-year surrender charge period applies to the reinstated Contract. The remaining surrender charge period, if any, is calculated based on the number of years since the original contract date;

• we apply the amount received from the other company (“reinstatement amount”) and the amount of the surrender charge you paid when you surrendered the Contract ;

• these amounts are priced on the valuation date the money from the other company is received by us;

• commissions are not paid on the reinstatement amounts; and

• new data page is sent to your address of record.

If you have any of the optional riders, rider fees will apply for the period between the date you requested termination and the date your contract was reinstated.

If you have any of the optional riders, rider benefits will be adjusted when the amount originally surrendered differs from the reinstatement amount.

Reports

We will mail to you a statement, along with any reports required by state law, of your current accumulated value at least once per year prior to the annuitization date. After the annuitization date, any reports will be mailed to the person receiving the annuity benefit payments.

Quarterly statements reflect purchases and surrenders occurring during the quarter as well as the balance of units owned and accumulated values.

Important Information About Customer Identification Procedures

To help the government fight the funding of terrorism and money laundering activities, Federal law requires financial institutions to obtain, verify, and record information that identifies each person who opens an account. When you open an account, we will ask for your name, address, date of birth, and other information that will allow us to verify your identity. We may also ask to see your driver’s license or other identifying documents.

If concerns arise with verification of your identification, no transactions will be permitted while we attempt to reconcile the concerns. If we are unable to verify your identity within 30 days of our receipt of your initial purchase payment, the account(s) will be closed and redeemed in accordance with normal redemption procedures.

We do not knowingly sell annuities that are for the benefit of a business/organization that is illegal under Federal and/or State law (such as a marijuana clinic), or a person who owns or receives income from such an entity or whose source of funds is illegal.

34

RIGHTS RESERVED BY THE COMPANY

We reserve the right to make certain changes if, in our judgment, they best serve the interests of you and the annuitant or are appropriate in carrying out the purpose of the Contract. Any changes will be made only to the extent and in the manner permitted by applicable laws. Also, when required by law, we will obtain your approval of the changes and approval from any appropriate regulatory authority. Approvals may not be required in all cases. Examples of the changes the Company may make include:

• transfer assets in any division to another division or to the Fixed Account;

• add, combine or eliminate a division(s);

• substitute the units of a division for the units of another division:

• if units of a division are no longer available for investment; or

• if in our judgment, investment in a division becomes inappropriate considering the purposes of the Separate Account.

Frequent Trading and Market-Timing (Abusive Trading Practices)

This Contract is not designed for frequent trading or market timing activity of the divisions. If you intend to trade frequently and/or use market timing investment strategies, you should not purchase this Contract. The Company does not accommodate market timing.

We consider frequent trading and market timing activities to be abusive trading practices because they:

• Disrupt the management of the underlying mutual funds by:

• forcing the fund to hold short-term (liquid) assets rather than investing for long term growth, which results in lost investment opportunities for the fund;

• causing unplanned portfolio turnover;

• Hurt the portfolio performance of the underlying mutual funds; and

• Increase expenses of the underlying mutual fund and separate account due to:

•increased broker-dealer commissions; and

•increased recordkeeping and related costs.

If we are not able to identify such abusive trading practices, the abuses described above will negatively impact the Contract and cause investors to suffer the harms described.

We have adopted policies and procedures to help us identify and prevent abusive trading practices. In addition, the underlying mutual funds monitor trading activity to identify and take action against abuses. While our policies and procedures are designed to identify and protect against abusive trading practices, there can be no certainty that we will identify and prevent abusive trading in all instances. When we do identify abusive trading, we will apply our policies and procedures in a fair and uniform manner.

If we, or an underlying mutual fund that is a division with the Contract, deem abusive trading practices to be occurring, we will take action that may include, but is not limited to:

• Rejecting transfer instructions from a Contract owner or other person authorized by the owner to direct transfers;

• Restricting submission of transfer requests by, for example, allowing transfer requests to be submitted by 1st class U.S. mail only and disallowing requests made via the internet, by facsimile, by overnight courier or by telephone;

• Limiting the number of unscheduled transfers during a Contract year to no more than 12;

• Prohibiting you from requesting a transfer among the divisions for a minimum of thirty days where there is evidence of at least one round-trip transaction (exchange or redemption of shares that were purchased within 30 days of the exchange/redemption) by you; and

• Taking such other action as directed by the underlying mutual fund.

We will support the underlying mutual funds’ right to accept, reject or restrict, without prior written notice, any transfer requests into a fund.

In some instances, a transfer may be completed prior to a determination of abusive trading. In those instances, we will reverse the transfer (within two business days of the transfer) and return the Contract to the investment option holdings it had prior to the transfer. We will give you notice in writing in this instance.

35

DISTRIBUTION OF THE CONTRACT

The Company has appointed Principal Securities, Inc. ("PSI") (Des Moines, Iowa 50392-0200), a broker-dealer registered under the Securities Exchange Act of 1934, a member of the Financial Industry Regulatory Authority and affiliate of the Company, as the distributor and principal underwriter of the Contract. PSI is paid 6.5% of purchase payments by the Company for the distribution of the Contract. PSI also receives 12b-1 fees in connection with purchases and sales of certain mutual funds underlying the Contracts. The 12b-1 fees for the underlying mutual funds are shown in this Contract prospectus in Summary of Expense, Annual Underlying Mutual Fund Expenses.

Applications for the Contracts were solicited by registered representatives of PSI or such other broker-dealers as have entered into selling agreements with PSI. Such registered representatives act as appointed agents of the Company under applicable state insurance law and must be licensed to sell variable insurance products.

PERFORMANCE CALCULATION

The Separate Account may publish advertisements containing information (including graphs, charts, tables and examples) about the hypothetical performance of its divisions for this Contract as if the Contract had been issued on or after the date the underlying mutual fund in which the division invests was first offered. The hypothetical performance from the date of the inception of the underlying mutual fund in which the division invests is calculated by reducing the actual performance of the underlying mutual fund by the fees and charges of this Contract as if it had been in existence.

The yield and total return figures described below vary depending upon market conditions, 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. 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. For further information on how the Separate Account calculates yield and total return figures, see the SAI.

From time to time the Separate Account advertises its Money Market Division’s “yield” and “effective yield” for these Contracts. 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 in the division over a 7-day period (which period is 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” is slightly higher than the “yield” because of the compounding effect of the assumed reinvestment.

The Separate Account also advertises 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 accumulated value.

FEDERAL TAX MATTERS

The following description is a general summary of the tax rules, primarily related to federal income taxes, which in our opinion are currently in effect. These rules are based on laws, regulations and interpretations which are subject to change at any time. This summary is not comprehensive and is not intended as tax advice. Federal estate and gift tax considerations, as well as state and local taxes, may also be material. You should consult a tax advisor about the tax implications of taking action under a Contract or related retirement plan.

Taxation of Non-Qualified Contracts

Non-Qualified Contracts

Section 72 of the Internal Revenue Code (Code) governs the income taxation of annuities in general.

• Purchase payments made under non-qualified Contracts are not excludable or deductible from your gross income or any other person’s gross income.

• An increase in the accumulated value of a non-qualified Contract owned by a natural person resulting from the investment performance of the Separate Account or interest credited to the DCA Plus Accounts and the Fixed Account is generally not taxable until paid out as surrender proceeds, death benefit proceeds, or otherwise.

• Generally, owners who are non-natural persons are immediately taxed on any increase in the accumulated value unless the non-natural person is acting as an agent for a natural person.

36

The following discussion applies generally to Contracts owned by natural persons.

• Surrenders or partial surrenders are taxed as ordinary income to the extent of the accumulated income or gain under the Contract.

• The value of the Contract pledged or assigned is taxed as ordinary income to the same extent as a partial surrender.

• Annuity benefit payments:

• The basic rule for taxing annuity benefit payments is that part of each annuity benefit payment is considered a nontaxable return of the investment in the contract and part is considered taxable income. An “exclusion ratio” is applied to each annuity benefit payment to determine how much of the payment is excludable from gross income. The remainder of the annuity benefit payment is includable in gross income for the year received.

• The “investment in the contract” is generally the total of the purchase payments made less any tax-free return of premiums.

• After the investment in the Contract is paid out, the full amount of any annuity benefit payment is taxable.

For purposes of determining the amount of taxable income resulting from distributions, all Contracts and other annuity contracts issued by us or our affiliates to the same owner within the same calendar year are treated as if they are a single contract.

Transfer of ownership may have tax consequences to the owner. For owners who are non-natural persons changing the annuitant may have tax consequences to the owner. Please consult with your tax advisor before changing the owner or annuitant on your Contract.

Required Distributions for Non-Qualified Contracts

In order for a non-qualified Contract to be treated as an annuity contract for federal income tax purposes, the Code requires:

• If the person receiving payments dies on or after the annuitization date but prior to the time the entire interest in the Contract has been distributed, the remaining portion of the interest is distributed at least as rapidly as under the method of distribution being used as of the date of that person’s death.

• If you die prior to the annuitization date, the entire interest in the Contract will be distributed:

• within five years after the date of your death; or

• as annuity benefit payments (or similar periodic payments) which begin within one year of your death and which are made over the life of your designated beneficiary or over a period not extending beyond the life expectancy of that beneficiary.

Generally, unless the beneficiary elects otherwise, the above requirements are satisfied prior to the annuitization date by paying the death benefit in a single payment, subject to proof of your death. The beneficiary may elect, by written request, to receive an annuity benefit payment option instead of a single payment.

If your designated beneficiary is your surviving spouse, the Contract may be continued with your spouse deemed to be the new owner for purposes of the Code. When the owner receiving payments is not a natural person, the required distributions provided for in the Code apply upon the death of the annuitant.

Early Distribution Penalty

• If you take a premature distribution from the Contract, you may incur a 10% income tax penalty, unless the distribution is:

• made on or after you reach age 59½;

• made to a beneficiary on or after your death;

• made upon your disability as defined in the Internal Revenue Code;

• part of a series of substantially equal periodic payments for the life or life expectancy of you or you and your designated beneficiary;

• made under an immediate annuity contract; or

• allocable to contributions made prior to August 14, 1982.

Tax-Free Exchanges

Under Section 1035 of the Code, the exchange of one annuity contract for another is not a taxable transaction if the same owner is on each contract in the exchange, but may be reportable to the IRS.

Net Investment Income Tax

The Net Investment Income Tax is imposed at a rate of 3.8% on net investment income for higher tax bracket individuals.

37

This tax may apply to an individual’s net investment income if the individual’s modified Adjustable Gross Income exceeds $200,000 for a single filer or $250,000 for a married filing jointly filer. The tax applies to income from interest, dividends, annuities, royalties and rents not obtained in a normal trade of business. The tax may also apply to certain trusts and estates with net investment income.

Income from annuities that are part of a qualified retirement plan (as described in the following section) are not treated as investment income for the purpose of this new tax and thus are not subject to the new 3.8% rate but may be includible for purposes of determining whether the applicable Net Investment Income Tax income limits are exceeded.

Taxation of Qualified Contracts

Tax-Qualified Contracts: IRA, SEP, and SIMPLE-IRA

The Contract may be used to fund IRAs, SEPs, and SIMPLE-IRAs.

• IRA — An Individual Retirement Annuity (IRA) is a retirement savings annuity. Contributions grow tax deferred.

• SEP-IRA — SEP stands for Simplified Employee Pension and is a form of IRA. A SEP allows you, as an employer, to provide retirement benefits for your employees by contributing to their IRAs.

• SIMPLE-IRA — SIMPLE stands for Savings Incentive Match Plan for Employees. A SIMPLE-IRA allows employees to save for retirement by deferring salary on a pre-tax basis and receiving predetermined company contributions.

The tax rules applicable to owners, annuitants and other payees vary according to the type of plan and the terms and conditions of the plan itself. In general, purchase payments made under a retirement program recognized under the Code are excluded from the participant’s gross income for tax purposes prior to the annuity benefit payment date (subject to applicable state law). The portion, if any, of any purchase payment made that is not excluded from their gross income is their investment in the Contract. Aggregate deferrals under all plans at the employee’s option may be subject to limitations.

Tax-qualified retirement arrangements, such as IRAs, SEPs, and SIMPLE-IRAs, aretax-deferred. You derive no additional benefit from the tax deferral feature of theannuity. Consequently, an annuity should be used to fund an IRA, or other tax qualified retirement arrangement to benefit from the annuity’s features other than tax deferral. These features may include guaranteed lifetime income, death benefits without surrender charges, guaranteed caps on fees, and the ability to transfer among investment options without sales or withdrawal charges.

The tax implications of these plans are further discussed in the SAI under the heading Taxation Under Certain Retirement Plans. Check with your tax advisor for the rules which apply to your specific situation.

Premature Distributions: There is a 10% additional penalty tax under the Code on the taxable portion of a “premature distribution” from IRAs, IRA rollovers, SEP-IRAs and SIMPLE-IRAs. The tax penalty is increased to 25% in the case of distributions from SIMPLE-IRAs during the first two years of participation in the SIMPLE IRA. Generally, an amount is a “premature distribution” unless the distribution is:

• made on or after you reach age 59½;

• made to a beneficiary on or after your death;

• made upon your disability as defined in the Internal Revenue Code;

• part of a series of substantially equal periodic payments for the life or life expectancy of you or you and your designated beneficiary;

• made to pay certain deductible medical expenses;

• for health insurance premiums while unemployed;

• for first home purchases (up to $10,000);

• for qualified higher education expenses;

• for qualified disaster tax relief distributions;

• for qualified reservist distributions;

• for amounts levied by the IRS directly against your IRA; or

• a qualified birth or adoption distribution (up to $5,000).

For more information regarding premature distributions, please reference IRS Publication 590-B and consult your tax advisor.

38

Rollover IRAs

If you receive a lump-sum distribution from a qualified retirement plan, tax-sheltered annuity or governmental 457(b) plan, you may maintain the tax-deferred status of the distribution by rolling it over into an eligible retirement plan or IRA. You can accomplish this by electing a direct rollover from the plan, or you can receive the distribution and roll it over into an eligible retirement plan or IRA within 60 days. However, if you do not elect a direct rollover from the plan, the plan is required to withhold 20% of the taxable portion of the distribution. This amount is sent to the IRS as income tax withholding to be credited against your taxes. Amounts received prior to age 59½ and not rolled over may be subject to an additional 10% penalty tax. You may roll over amounts from a qualified plan directly to a Roth IRA. As part of this rollover, previously taxed deferred funds from the qualified plan are converted to after-tax funds under a Roth IRA. Generally, the entire rollover is taxable (unless it includes after-tax dollars) and is included in gross income in the year of the rollover/conversion. For more information, please consult your tax advisor.

In addition, not more frequently than once every twelve months, an owner may execute one tax-free indirect rollover from one IRA to another, subject to the 60-day limitation. The once-per-year limitation on rollovers does not apply to direct transfers of funds between IRA providers or to Roth IRA conversions. For more information, please consult your tax advisor.

Roth IRAs

The Contract may be purchased to fund a Roth IRA. Contributions to a Roth IRA are not deductible from taxable income. Subject to certain limitations, a traditional IRA, SEP-IRA or SIMPLE-IRA may be converted into a Roth IRA or a distribution from such an arrangement may be rolled over to a Roth IRA. However, a conversion or a rollover to a Roth IRA is not excludable from gross income. If certain conditions are met, qualified distributions from a Roth IRA are tax-free. For more information, please contact your tax advisor.

Required Minimum Distributions for IRAs

The Required Minimum Distribution (RMD) regulations dictate when individuals must start taking payments from their IRA. Generally speaking, RMDs for IRAs must begin no later than April 1 following the close of the calendar year in which you turn 72. Thereafter, the RMD is required no later than December 31 of each calendar year.

The RMD rules apply to traditional IRAs, as well as SEP-IRAs and SIMPLE-IRAs, during the lifetime and after the death of IRA owners. They do not, however, apply to Roth IRAs during the lifetime of the Roth IRA owner. If an individual owns more than one IRA, the RMD amount must be determined for each, but the actual distribution can be satisfied from a combination of one or more of the owner’s IRAs. Roth IRAs may not be aggregated with other IRAs, but may be aggregated with other Roth IRAs.

Failure to comply with the RMD rules can result in tax penalty of 50% on the amount by which the RMD in any year exceeds the amount actually distributed in that year.

Note: Required minimum distributions (RMDs) for 2020 are waived for certain defined contribution plans (including 401(k), 403(b), and governmental 457(b) plans) and IRAs. Beneficiaries receiving distributions over a 5-year period can waive the distribution for 2020 and determine the 5-year period without regard to calendar year 2020 .

Withholding

Annuity benefit payments and other amounts received under the Contract are subject to income tax withholding unless the recipient elects not to have taxes withheld. The amounts withheld vary among recipients depending on the tax status of the individual and the type of payments from which taxes are withheld.

Notwithstanding the recipient’s election, withholding may be required on payments delivered outside the United States. Moreover, special withholding rules may require us to disregard the recipient’s election if the recipient fails to supply us with a taxpayer identification number (social security number for individuals), or if the Internal Revenue Service notifies us that the taxpayer identification number provided by the recipient is incorrect.

39

MUTUAL FUND DIVERSIFICATION

The United States Treasury Department has adopted regulations under Section 817(h) of the Internal Revenue Code which establish standards of diversification for the investments underlying the Contracts. Under this Internal Revenue Code Section, Separate Account investments must be adequately diversified in order for the increase in the value of non-qualified Contracts to receive tax-deferred treatment. In order to be adequately diversified, the portfolio of each underlying mutual fund must, as of the end of each calendar quarter or within 30 days thereafter, have no more than 55% of its assets invested in any one investment, 70% in any two investments, 80% in any three investments and 90% in any four investments. Failure of an underlying mutual fund to meet the diversification requirements could result in tax liability to non-qualified Contract holders.

The investment opportunities of the underlying mutual funds could conceivably be limited by adhering to the above diversification requirements. This would affect all owners, including owners of Contracts for whom diversification is not a requirement for tax-deferred treatment.

STATE REGULATION

The Company is subject to the laws of the State of Iowa governing insurance companies and to regulation by the Insurance Department of the State of Iowa. An annual statement in a prescribed form must be filed by March 1 in each year covering our operations for the preceding year and our financial condition on December 31 of the prior year. Our books and assets are subject to examination by the Commissioner of Insurance of the State of Iowa, or the Commissioner’s representatives, at all times. A full examination of our operations is conducted periodically by the National Association of Insurance Commissioners. Iowa law and regulations also prescribe permissible investments, but this does not involve supervision of the investment management or policy of the Company.

In addition, we are subject to the insurance laws and regulations of other states and jurisdictions where we are licensed to operate. Generally, the insurance departments of these states and jurisdictions apply the laws of the state of domicile in determining the field of permissible investments.

GENERAL INFORMATION

Reservation of Rights

The Company reserves the right to:

• increase the minimum amount for each purchase payment to not more than $1,000; and

• terminate a Contract and send you the accumulated value if no purchase payments are made during two consecutive calendar years and the accumulated value (or total purchase payments less partial surrenders and applicable surrender charges) is less than $2,000. The Company will first notify you of its intent to exercise this right and give you 60 days to increase the accumulated value to at least $2,000.

Legal Opinions

Legal matters applicable to the issue and sale of the Contracts, including our right to issue Contracts under Iowa Insurance Law, have been passed upon by Doug Hodgson, Counsel.

Legal Proceedings

There are no legal proceedings pending to which Separate Account B is a party or which would materially affect Separate Account B.

Other Variable Annuity Contracts

The Company currently offers other variable annuity contracts that participate in Separate Account B. In the future, we may designate additional group or individual variable annuity contracts as participating in Separate Account B.

Householding

To avoid sending duplicate copies of materials to owners, only one copy of the prospectus and annual and semi-annual reports for the funds will be mailed to owners having the same name and address on our records. The consolidation of these mailings, called householding, benefits us through reduced mailing expense. If you want to receive multiple copies of these materials, you may call us at 1-800-852-4450. You may also notify us in writing. Individual copies of prospectuses and reports will be sent to you within thirty (30) days after we receive your request to stop householding.

40

Payments to Financial Intermediaries

The Company pays compensation to broker-dealers, financial institutions, and other parties (“Financial Intermediaries”) for the sale of the Contract according to schedules in the sales agreements and other agreements reached between the Company and the Financial Intermediaries. Such compensation generally consists of commissions on purchase payments made on the Contract. The Company and or its affiliates may also pay other amounts (“Additional Payments”) that include, but are not limited to, marketing allowances, expense reimbursements, and educational payments. These Additional Payments are designed to provide incentives for the sale of the Contracts as well as other products sold by the Company and may influence the Financial Intermediaries or their registered representatives to recommend the purchase of this Contract over competing annuity contracts or other investment options. You may ask your registered representative about these differing and divergent interests, how your registered representative is personally compensated, and how your registered representative’s broker-dealer is compensated for soliciting applications for the Contract.

We and/or our affiliates provide services to and/or funding vehicles for benefit and retirement plans. We and our affiliates may pay a bonus or other consideration or incentive to brokers or dealers:

• if a participant in such a benefit or retirement plan purchases a product with the assistance of a registered representative of an affiliate of ours;

• if a participant in such a retirement plan establishes a rollover individual retirement account with the assistance of a registered representative of an affiliate of ours;

• if the broker or dealer sold the funding vehicle the benefit or retirement plan utilizes; or

• based on the broker’s or dealer’s relationship to the benefit or retirement plan.

The broker or dealer may pay to its financial professionals some or all of the amounts we pay to the broker or dealer.

Conflicts of Interest Related to Underlying Mutual Funds

Compensation and Underlying Mutual Fund Selection

When selecting the underlying mutual funds, we consider each such fund’s investment strategy, asset class, manager’s reputation, and performance. We also consider the amount of compensation that we receive from the underlying mutual funds, their advisers, sub-advisers, or their distributors, which can be significant. Additionally, we offer certain underlying mutual funds at least in part because they are managed by an affiliate.

Compensation We Receive from Underlying Mutual Funds

The Company and certain of our affiliates receive compensation from certain underlying mutual funds pursuant to Rule 12b-1 under the 1940 Act. This compensation is paid out of an underlying mutual fund’s assets and is as much as 0.25% of the average net assets of an underlying mutual funds that are attributable to the variable life insurance products issued by us and our affiliates that offer the particular fund (the Company’s variable contracts). An investment in an underlying mutual funds with a 12b-1 fee will increase the cost of your investment.

Compensation We Receive from Underlying Mutual Fund Advisors

We and certain of our affiliates also receive compensation from the advisers and sub-advisers to some of the underlying mutual funds. We use this compensation for such purposes as paying expenses that we incur in promoting, issuing, distributing and administering the Policy and providing services on behalf of the underlying mutual funds in our role as intermediary. Some advisers and sub-advisers pay us more than others; some advisers and sub-advisers do not pay us any such compensation. Such compensation is not reflected in an underlying mutual fund's expenses in cases where it is not paid directly out of such fund’s assets, or if it is derived, in whole or in part, from the advisory fee deducted from fund assets. Owners, through their indirect investment in the underlying mutual funds, bear the costs of these advisory fees.

Other Conflicts of Interest

The underlying mutual funds are available to registered separate accounts offering variable annuity and variable life products of other affiliated and unaffiliated insurance companies, as well as to the separate account and other separate accounts of the Company. Although we do not anticipate any disadvantages to these arrangements, it is possible that a material conflict may arise between the interests of the separate account and one or more of the other separate accounts participating in the underlying mutual funds. A conflict may occur, for example, as a result of a change in law affecting the operations of variable life and variable annuity separate accounts, differences in the voting instructions of the owners and payees and those of other insurance companies, or some other reason. In the event of a conflict of interest, we will take steps necessary to protect owners and payees, including withdrawing the Separate Account from participation in the underlying mutual funds involved in the conflict or substituting shares of other funds.

Charges and Expenses

The new contract and your old contract have different annual expenses, different transaction charges, and different investment options that may result in different underlying mutual fund expenses.

Surrender Charges

Under the exchange offer, surrender charges will not apply on any amounts transferred from the old contract to the new contract. Surrender charges under the new contract will only apply to new contract premium payments.

Death Benefit

The death benefit in the new contract will be calculated as specified in the prospectus for the new contract. At the time of the exchange, the death benefit from the old contract will be transferred to the new contract and will be adjusted for new premium payments made and withdrawals taken under the new contract.

Upon your death, we will pay the greater of the new contract death benefit or the old contract death benefit adjusted as described above.

GMWB Rider

The new contract offers GMWB riders (Target Income Protector, Flexible Income Protector, or Flexible Income Protector Plus) not available under the old contract. A GMWB rider allows you to take certain guaranteed annual withdrawals, regardless of your Contract accumulated value.

Your Contract can only have one GMWB rider. You must qualify for the Target Income Protector, Flexible Income Protector, or Flexible Income Protector Plus rider when you purchase the new contract.

The Target Income Protector, Flexible Income Protector, or Flexible Income Protector Plus rider may not be terminated for 5 contract years following the rider effective date.

63

A GMWB rider results in restriction of your Contract investment options to the more limited GMWB investment options (additional information is included in the new contract prospectus). The GMWB investment options reflect a balanced investment objective that is intended to support the rider guarantees. If your investment objective is aggressive growth, the rider investment restrictions may not support your investment objective.

Target Income Protector

The Target Income Protector rider offers an annual Step-Up feature. The GMWB Step-Up can increase your rider For Life withdrawal benefit payments if your Contract accumulated value increases. The Contract accumulated value increases whenever additional premium payments are added or the division values rise with market growth.

The Target Income Protector rider also offers a GMWB Bonus. The GMWB Bonus rewards you annually for not taking a withdrawal in the years that a bonus is available. The GMWB Bonus amount will provide an increase to your rider withdrawal benefit payments. The GMWB Bonus does not increase your Contract accumulated value.

The Target Income Protector rider provides your beneficiary(ies) with the GMWB Death Benefit.

Flexible Income Protector

The Flexible Income Protector rider offers an annual Step-Up feature. The GMWB Step-Up can increase your rider For Life withdrawal benefit payments if your Contract accumulated value increases. The Contract accumulated value increases whenever additional premium payments are made or the division values rise with market growth.

The Flexible Income Protector rider does not offer a GMWB Bonus.

The Flexible Income Protector rider provides your beneficiary(ies) with the GMWB Death Benefit.

Flexible Income Protector Plus

The Flexible Income Protector Plus rider offers an annual Step-Up feature. The GMWB Step-Up can increase your rider For Life withdrawal benefit payments if your Contract accumulated value increases. The Contract accumulated value increases whenever additional premium payments are added or the division values rise with market growth.

The Flexible Income Protector Plus rider also offers a GMWB Bonus. This rider includes an annual bonus for not taking withdrawals for a specific number of years immediately following the purchase of a Contract. The GMWB Bonus amount will provide an increase to your rider For Life withdrawal benefit payments. The GMWB Bonus does not increase your Contract accumulated value.

The Flexible Income Protector Plus rider provides your beneficiary(ies) with the GMWB Death Benefit.

It is important that you review the new contract prospectus in its entirety for additional information regarding the Target Income Protector, Flexible Income Protector, and Flexible Income Protector Plus riders and whether a GMWB rider is appropriate for your needs.

Tax Matters

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 3000, 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 non-continuous. As the principal underwriter, PSI is paid for the distribution of the Contract. For the last three fiscal years PSI has received and retained the following commissions:

2019 received/retained	2018 received/retained	2017 received/retained
$8,369,834/$0	$8,705,701/$0	$9,203,089/$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.

The Contract was not offered prior to June 16, 1994. Certain of the underlying funds 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.

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 these Contracts. 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 seven-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, 2019
For Contracts	7-day annualized yield	7-day effective yield
without a surrender charge or a Purchase Payment Credit Rider	0.08%	0.08%
with a surrender charge but without a Purchase Payment Credit Rider	-5.92%	-5.92%
without a surrender charge but with a Purchase Payment Credit Rider	-0.52%	-0.52%

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. In this calculation for the Contract without the Purchase Payment Credit Rider, the ending value is reduced by a surrender charge that decreases from 6% to 0% over a period of 7 years. For the calculations relating to the Contract with the Purchase Payment Credit Rider, the ending value is reduced by a surrender charge that decreases from 8% to 0% over a period of 9 years. 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 and Deductions” in the Prospectus for a discussion of surrender charges.

Following are the hypothetical average annual total returns for the period ending December 31, 2019 assuming the Contract had been offered as of the effective dates of the underlying mutual funds in which the divisions invest:

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
2019	$6,000	$12,000
2020	$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 2019 and 2020. 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 $196,000 and $206,000 in 2020.

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
2019	$103,000	$123,000	2019	$64,000	$74,000
2020	$104,000	$124,000	2020	$65,000	$75,000

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 59½ 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).

12

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.

Note: Required minimum distributions (RMDs) for 2020 are waived for certain defined contribution plans (including 401(k), 403(b), and governmental 457(b) plans) and IRAs. Beneficiaries receiving distributions over a 5-year period can waive the distribution for 2020 and determine the 5-year period without regard to calendar year 2020 .

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 $57,000 for 2020.

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.

13

Salary Reduction Simplified Employee Pension Plan (SAR/SEP)
Year	Elective Deferral	Catch-up Contribution
2019	$19,000	$6,000
2020	$19,500	$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.

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 2020.

Elective contribution amounts made under the salary reduction portions (i.e., those subject to the $13,500 limit in 2020) of a SIMPLE IRA plan are counted in the overall limit on elective deferrals by any individual. For example, if in 2020, an individual under age 50 defers the maximum of $13,500 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 $6,000 ($19,500 - $13,500) to the 401(k) plan for 2020.

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
2019	$13,000	$3,000	$19,000
2020	$13,500	$3,000	$19,500

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
2019	$6,000	$1,000
2020	$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 2019 and 2020.

For 2020, the maximum contribution is phased out for single taxpayers with adjusted gross income between $124,000 and $139,000 and for joint filers with adjusted gross income between $196,000 and $206,000 (see chart below).

Modified Adjusted Gross Income Limits – 2019
Single/Head of Household	Married Filing Joint	ROTH IRA Contribution
< $124,000	< $196,000	Full Contribution
> $124,000 but < $139,000	> $196,000 but < $206,000	Partial Contribution*
> $139,000	> $206,000	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 59 ½, 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.

FINANCIAL STATEMENTS

APPENDIX A - Principal Life Insurance Company Separate Account B Financials

A-1

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Principal Life Insurance Company and Contract Owners of Principal Life Insurance Company Separate Account B

Opinion on the Financial Statements

We have audited the accompanying statements of assets and liabilities of each of the subaccounts listed in the Appendix that comprise Principal Life Insurance Company Separate Account B (the Separate Account), as of December 31, 2019, the related statements of operations and the statements of changes in net assets for each of the periods indicated in the Appendix, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each subaccount as of December 31, 2019, 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, 2019,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.

/s/ Ernst & Young LLP

We have served as the Separate Account’s auditor since 1970.

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.

Investments

Investments are stated at the closing net asset value (“NAV”) per share on December 31, 2019. 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.

Pension Builder Plus and Pension Builder Plus-Rollover IRA 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 1.50% (1.00% for a Rollover IRA) of the asset value of each contract.

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 2019, 2018, 2017, 2016 and 2015 in accordance with the AICPA 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 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 contact options as discussed in Note 2.

(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.

7. Subsequent Events

The Separate Account performed an evaluation of subsequent events through March 27, 2020. 

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. The global impact of the outbreak has been rapidly evolving and many countries have reacted by instituting quarantines and restrictions on travel. Such measures, as well as the general uncertainty surrounding the dangers and impact of COVID-19, are creating significant disruption in supply chains and economic activity.  As COVID-19 continues to spread, the potential impacts, including a global, regional or other economic recession, are increasingly difficult to assess. These events, or fear of such an event, present material uncertainty and risk with respect to the Separate Account performance and financial results.

Report of Independent Auditors

The Board of Directors and Stockholders

Principal Life Insurance Company

We have audited the accompanying consolidated financial statements of Principal Life Insurance Company, which comprise the consolidated statements of financial position as of December 31, 2019 and 2018, and the related statements of operations, comprehensive income, stockholder’s equity and cash flows for each of the three years in the period ended December 31, 2019, and the related notes to the consolidated financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these financial statements in conformity with U.S. generally accepted accounting principles; this includes 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.

Auditor’s Responsibility

Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the financial statements 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 entity’s internal control. Accordingly, we express no such opinion.An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Principal Life Insurance Company at December 31, 2019 and 2018, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles.

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 pages 55-59 be presented to supplement the financial statements. Such information, 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, 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.

Notes to Consolidated Financial StatementsDecember 31, 2019

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.

On May 1, 2017, we sold our ownership interest in Principal Global Investors, LLC (“PGI LLC”) to PFS in connection with a corporate reorganization designed to better utilize and allocate capital internally. PGI LLC met the criteria to be reported as a discontinued operation. See Note 2, Discontinued Operations, for further details. Information included in the notes to the financial statements excludes information applicable to the discontinued operations, unless otherwise noted.

We evaluated subsequent events through March 13, 2020, 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 5, 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 certain market-based options or guarantees associated with deposit or account balance contracts, will be measured at fair value. The periodic change in fair value related to instrument-specific credit risk will be recognized in OCI while the remaining change in fair value will be recognized in net income. 3.    Deferred acquisition costs (“DAC”) 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 and 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, 2022	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; •    beginning to build key models; •    evaluating our key accounting policies; •    assessing the impact to our chart of accounts; •    developing format and content of new disclosures and •    evaluating transition requirements and impacts. As we progress through our implementation, we will be able to better assess the impact to our consolidated financial statements; however, we expect this guidance to significantly change how we account for many of our insurance and annuity products.
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. Early adoption is permitted.	January 1, 2020	We expect the guidance will reduce complexity and costs associated with performing a Step 2 test, should one be needed in the future. However, the impact of eliminating the Step 2 test from any such future impairment assessment will be dependent on modeling factors that are not currently determinable. We do not expect this guidance to have a material impact on our consolidated financial statements.

Notes to Consolidated Financial Statements – (continued)December 31, 2019

Description	Date of adoption	Effect on our consolidated financial statements or other significant matters
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. This guidance also expands the required credit loss disclosures and will be applied using a modified retrospective approach by recording a cumulative effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. Early adoption is permitted.	January 1, 2020	The guidance will be adopted using the modified retrospective approach. Our evaluation process is complete and included, but was not limited to, identifying financial assets within scope of the guidance, developing and refining CECL models for the relevant assets, preparing quarterly estimates of the cumulative effect of adoption, developing and refining necessary internal controls and preparing the required financial statement disclosures. The financial statement changes are not material and will result in an immaterial reduction to stockholder’s equity.
Standards adopted:
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 is 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.

Description	Date of adoption	Effect on our consolidated financial statements or other significant matters
Leases This authoritative guidance requires lessee recognition of lease assets and lease liabilities on the balance sheet. The concept of an operating lease, where the lease assets and liabilities are off balance sheet, 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 and comparative periods were not restated. Further details are included under the caption “Adoption of Lease Guidance” and in Note 14, Contingencies, Guarantees, Indemnifications and Leases.
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 7, Derivative Financial Instruments, for further details.
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.

Reclassification of certain tax effects from accumulated other   comprehensive income  This authoritative guidance permits a reclassification from accumulated other comprehensive income (“AOCI”) to retained earnings for the stranded tax effects resulting from U.S. tax legislation enacted on December 22, 2017, which is referred to as the ‘‘Tax Cuts and Jobs Act’’ (‘‘U.S. tax reform’’). The amount of that reclassification includes the change in corporate income tax rate, as well as an election to include other income tax effects related to the application of U.S. tax reform. The guidance also requires disclosures about stranded tax effects.	January 1, 2018	The effective date of the guidance was January 1, 2019; however, we elected to early adopt the guidance. The guidance was applied at the beginning of the period of adoption and comparative periods were not restated. We reclassified the stranded tax effects in AOCI resulting from U.S. tax reform, which includes the change in corporate income tax rate and an election to reclassify the tax effects of the one-time deemed repatriation tax. A reclassification of $242.0 million was recorded as an increase to AOCI and a decrease to retained earnings.
Revenue recognition This authoritative guidance replaces all general and most industry specific revenue recognition guidance currently prescribed by U.S. GAAP. The core principle is that an entity recognizes revenue to reflect the transfer of a promised good or service to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for that good or service. This guidance also provides clarification on when an entity is a principal or an agent in a transaction. In addition, the guidance updates the accounting for certain costs associated with obtaining and fulfilling a customer contract. The guidance may be applied using one of the following two methods: (1) retrospectively to each prior reporting period presented, or (2) retrospectively with the cumulative effect of initially applying the standard recognized at the date of initial application.	January 1, 2018	We adopted the guidance using the modified retrospective approach. The guidance did not have a material impact on our consolidated financial statements. A cumulative effect adjustment of $36.4 million was recorded as an increase to total stockholder’s equity. See Note 18, Revenues from Contracts with Customers, for further details.
Income tax - intra-entity transfers of assets This authoritative guidance requires entities to recognize current and deferred income tax resulting from an intra-entity asset transfer when the transfer occurs. Prior to issuance of this guidance, U.S. GAAP did not allow recognition of income tax consequences until the asset had been sold to a third party. This guidance requires adoption through a cumulative effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption.	January 1, 2018	We adopted the guidance using the modified retrospective approach. The guidance did not have a material impact on our consolidated financial statements.

Description	Date of adoption	Effect on our consolidated financial statements or other significant matters
Financial instruments - recognition and measurement This authoritative guidance addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The guidance eliminated the classification of equity securities into different categories (trading or available-for-sale) and requires equity investments to be measured at fair value with changes in the fair value recognized through net income. The guidance also updated certain financial instrument disclosures and eliminated the requirement to disclose the methods and significant assumptions used to estimate the fair value of financial instruments that are measured at amortized cost on the balance sheet.	January 1, 2018	We adopted this guidance using the modified retrospective approach. A cumulative effect adjustment of $0.1 million was recorded as an increase to AOCI and a corresponding decrease to retained earnings. The guidance did not have a material impact on our consolidated financial statements. See Note 6, Investments, for further details.
Nonfinancial asset derecognition and partial sales of nonfinancial   assets This authoritative guidance clarifies the scope of the recently established guidance on nonfinancial asset derecognition and the accounting for partial sales of nonfinancial assets. The guidance conforms the derecognition guidance on nonfinancial assets with the model for transactions in the new revenue recognition standard.	January 1, 2018	The guidance did not have a material impact on our consolidated financial statements.
Presentation of net periodic pension cost and net periodic   postretirement benefit cost This authoritative guidance requires that an employer disaggregate the service cost component from the other components of net benefit cost. The guidance also provides explicit guidance on the presentation of the service cost component and the other components of net benefit cost in the consolidated statement of operations and allows only the service cost component of net benefit cost to be eligible for capitalization.	January 1, 2018	The guidance did not have a material impact on our consolidated financial statements.
Definition of a business This authoritative guidance clarifies the definition of a business to assist with evaluating when transactions involving an integrated set of assets and activities (a “set”) should be accounted for as acquisitions or disposals of assets or businesses. The guidance requires that when substantially all of the fair value of the gross assets acquired or disposed of is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. The guidance also requires a set to include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output to be considered a business. Lastly, the guidance removes the evaluation of whether a market participant could replace missing elements and narrows the definition of outputs by more closely aligning it with how outputs are described in the revenue recognition guidance. The guidance will be applied prospectively.	January 1, 2018	The guidance did not have a material impact on our consolidated financial statements.
Employee share-based payment accounting This authoritative guidance changes certain aspects of accounting for and reporting share-based payments to employees including changes related to the income tax effects of share-based payments, tax withholding requirements and accounting for forfeitures. Various transition methods will apply depending on the situation being addressed.	January 1, 2017	The guidance was adopted prospectively as indicated by the guidance for each area of change and did not have a material impact on our consolidated financial statements.

Notes to Consolidated Financial Statements – (continued)December 31, 2019

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.

Adoption of Lease Guidance

On January 1, 2019, we adopted the guidance using the modified retrospective approach with the cumulative effect of initially applying the standard recognized at the date of adoption. We elected the package of practical expedients permitted under the transition guidance. In addition, we elected the hindsight practical expedient to determine the lease term for existing leases. We have agreements with lease and non-lease components, which we account for as a combined unit of account for all classes.

The impact of the guidance to our consolidated financial statements primarily related to the establishment of additional assets and liabilities of $102.2 million and $97.2 million, respectively. The difference between the additional assets and liabilities, net of deferred tax impacts, was recorded as a cumulative effect adjustment to retained earnings and increased total stockholder’s equity by $4.0 million.

Results of reporting periods beginning January 1, 2019, are presented under the new guidance, while prior period amounts are not adjusted and continue to be reported in accordance with our prior accounting. The guidance did not have a material impact on our consolidated statements of operations.

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 8, 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.

B-14

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

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 16, 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 equity securities, unrealized gains and losses related to hedged portions of fixed maturities, available-for-sale in fair value hedging relationships prior to 2019 and mark-to-market adjustments on fixed maturities, trading are reflected in net realized capital gains (losses). Beginning in 2019, 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.

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 classified as available-for-sale is adjusted for changes in fair value of hedged portions of securities in fair value hedging relationships and declines in value that are other than temporary. Impairments in value deemed to be other than temporary are 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.

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 $169.0 million and $207.7 million as of December 31, 2019 and 2018, respectively. Any impairment losses and any changes in valuation allowances are reported in net income.

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. 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.Any changes in the valuation allowances are reported in net realized capital gains (losses). We measure impairment based upon the difference between carrying value and estimated value less cost to sell. Estimated value is based on either the present value of expected cash flows discounted at the loan's effective interest rate, the loan's observable market price or the fair value of the collateral. If foreclosure is probable, the measurement of any valuation allowance is based upon the fair value of the collateral.    

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): other-than-temporary impairments of securities and subsequent realized recoveries, 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 mortgage loan valuation allowance provision, impairments of real estate held for investment and impairments of equity method investments. 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).

B-15

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

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 16, 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 and futures. 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 16, 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.

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 income statement 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. Prior to 2019, these changes in fair value were recorded in net realized capital gains (losses). 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.

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. 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-16

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

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.

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. 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.

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.

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

Participating business represented approximately 6%, 7% and 8% of our life insurance in force and 23%, 26% and 29% of the number of life insurance policies in force as of December 31, 2019, 2018 and 2017, respectively. Participating business represented approximately 31%, 34% and 39% of life insurance premiums for the years ended December 31, 2019, 2018 and 2017, 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 2019.

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 10, 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.

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 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.

B-19

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

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.

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. We may assume reinsurance from or cede reinsurance to other companies. 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, 2019 and 2018, we had $465.3 million and $450.4 million of net ceded reinsurance recoverables related to claims that have been received, respectively. As of December 31, 2019 and 2018, $457.2 million, or 98%, and $435.6 million, or 97%, were with our five largest ceded reinsurers, respectively. Our total amount recoverable from reinsurers includes net ceded reinsurance recoverables related to claims that have been received and reserves ceded to reinsurers; however, it does not reflect potentially offsetting impacts of collateral. As of December 31, 2019 and 2018, the total amount recoverable from reinsurers was $961.4 million and $920.8 million, respectively, and is recognized in premiums due and other receivables.

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. 

As of December 31, 2019 and 2018, the separate accounts included a separate account valued at $100.4 million and $94.9 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, we file income tax returns in all states and foreign jurisdictions in which we conduct 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. However, a specific exception to this rule was adopted effective January 1, 2018, to reclassify the stranded tax effects generated by U.S. tax reform from AOCI to retained earnings. Further details are included under the caption “Recent Accounting Pronouncements.”

2. Discontinued Operations

On May 1, 2017, we sold our ownership interest in PGI LLC to PFS. PGI LLC results are subsequently reported as discontinued operations and the results of operations have been removed from our results of continuing operations for all periods presented. Additionally, intercompany eliminations associated with PGI LLC are reported as discontinued operations and have been removed from our results of continuing operations for all periods presented. PGI LLC continues to provide asset management services for us.

3. 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, 2019, 2018 and 2017, we received $607.1 million, $520.7 million and $431.9 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 receivable from/(payable to) PFS of $(52.9) million and $64.2 million as of December 31, 2019 and 2018, respectively, and earned interest of $4.3 million, $4.9 million and $1.7 million during 2019, 2018 and 2017, 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 $3,958.9 million and $3,399.2 million as of December 31, 2019 and 2018, respectively. In addition, we recognized premiums and other fees of $672.3 million, $555.4 million and $498.9 million for the years ended December 31, 2019, 2018 and 2017, respectively, associated with this agreement. Furthermore, we recognized expenses of $869.1 million, $776.1 million and $700.3 million for the years ended December 31, 2019, 2018 and 2017, respectively, associated with this agreement.

Sale of Subsidiaries

On May 1, 2017, we sold our ownership interest in PGI LLC to PFS as part of a common control transaction. Accordingly, no gain or loss was recognized on the sale and the amount received in excess of book value was recorded in additional paid-in capital. We received $1,068.4 million in cash and a $300.0 million 10-year note from PFS, with the note balance approximating the carrying value of PGI LLC. The note bears interest at 2.885% with semi-annual principal and interest payments due in May and November each year. Subsequent to the sale, we paid an extraordinary dividend of $1,068.4 million to PFS with the cash proceeds received from the sale.

Following the sale of our ownership of PGI LLC, it continues to provide asset management services for us. We recognized $100.1 million, $103.6 million and $65.7 million of asset management fee expense for the years ended December 31, 2019, 2018 and 2017, respectively. Prior to the sale of PGI LLC, these expenses were eliminated upon consolidation.

Our ultimate parent, PFG, is a guarantor of notes received from PFS related to the sale of interests in subsidiaries. We recorded interest income on these notes of $9.8 million, $11.1 million and $9.4 million for the years ended December 31, 2019, 2018 and 2017, respectively.

Distribution of Affiliated Products

We receive commission fees, distribution fees and service fees from Principal Securities, Inc. and PGI LLC. Furthermore, we receive management and administrative fees for investments our products sold in the Principal Mutual Funds and Principal Variable Contracts. Fees and other revenues were $392.7 million, $412.0 million and $433.8 million for the years ended December 31, 2019, 2018 and 2017, respectively. In addition, we pay commission expense to affiliated registered representatives within Principal Securities, Inc. to sell proprietary products. Commission expense was $88.7 million, $82.6 million and $84.8 million for the years ended December 31, 2019, 2018 and 2017, respectively.

Benefit Plans

PFG is the sponsor of the qualified defined contribution plans for both employees and individual field agents. We were allocated plan expenses from PFG of $32.9 million, $32.1 million and $31.6 million during 2019, 2018 and 2017, respectively.

PFG is also the sponsor of the nonqualified deferred compensation plans for select employees and individual field agents. We were allocated plan expenses from PFG of $1.9 million, $2.0 million and $2.4 million during 2019, 2018 and 2017, respectively.

PFG is the sponsor of the defined benefit pension plans for both employees and individual field agents. We were allocated $46.7 million, $51.2 million and $48.4 million of pension expense from PFG during 2019, 2018 and 2017, respectively.

Other Agreements

Pursuant to certain regulatory requirements or otherwise in the ordinary course of business, we guarantee certain payments of our affiliates and have agreements with affiliates to provide and/or receive management, administrative and other services, all of which, individually and in the aggregate, are immaterial to our business, financial condition and net income.

4. Goodwill and Other Intangible Assets

Goodwill

The carrying amount of goodwill did not change during 2019 and 2018.

Finite Lived Intangible Assets

Amortized intangible assets that continue to be subject to amortization over a weighted average remaining expected life of 14 years were as follows:

The amortization expense for intangible assets with finite useful lives was $2.6 million, $2.6 million and $2.6 million for 2019, 2018 and 2017, respectively. As of December 31, 2019, the estimated amortization expense for the next five years is as follows (in millions):

Year ending December 31:
	2020	$	2.4
	2021		2.2
	2022		2.0
	2023		1.2
	2024		1.1

5. 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, 2019 and December 31, 2018.

Consolidated Variable Interest Entities

Grantor Trust

We contributed undated subordinated floating rate notes to a grantor trust. The trust separated its cash flows by issuing an interest-only certificate and a residual certificate related to each note contributed. Each interest-only certificate entitles the holder to interest on the stated note for a specified term, while the residual certificate entitles the holder to interest payments subsequent to the term of the interest-only certificate and to all principal payments. We retained the interest-only certificates and the residual certificates were subsequently sold to third parties. We determined the grantor trust is a VIE due to insufficient equity to sustain it. We determined we are the primary beneficiary as a result of our contribution of securities into the trust and our significant continuing interest in the trust.

Commercial Mortgage-Backed Securities

We sold commercial mortgage loans to a real estate mortgage investment conduit trust. The trust issued various commercial mortgage-backed securities ("CMBS") certificates using the cash flows of the underlying commercial mortgage loans it purchased. This was considered a VIE due to insufficient equity to sustain itself. We determined we were the primary beneficiary as we retained the special servicing role for the assets within the trust as well as the ownership of the bond class that controls the unilateral kick-out rights of the special servicer. The trust was unwound in the third quarter of 2019.

B-24

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

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.

Sponsored Investment Fund

We invest in certain series of an investment fund. These series are VIEs as the equity holders of each series lack the power to direct the most significant activities of the VIE. We determined we are the primary beneficiary of these series as our interest is more than insignificant and collectively we have the power to direct the most significant activities of the fund.

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, 2019				December 31, 2018
	Total		Total		Total		Total
	assets		liabilities		assets		liabilities
	(in millions)
Grantor trust (1)	$	99.9	$	98.6	$	95.0	$	89.4
CMBS		—		—		6.4		—
Real estate (2)		479.7		88.0		379.2		70.6
Sponsored investment fund (3)		19.9		—		37.7		—
Total	$	599.5	$	186.6	$	518.3	$	160.0

(1) The assets of the grantor trust are primarily fixed maturities, available-for-sale. The liabilities are primarily other liabilities that reflect an embedded derivative of the forecasted transaction to deliver the underlying securities.

(2) The assets of the real estate VIEs primarily include real estate and cash. Liabilities primarily include long-term debt and other liabilities.

(3) The assets of the sponsored investment fund include other investments.

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.

Unconsolidated VIEs include certain 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.

B-25

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

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, invest in and have other interests 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.

The carrying value and maximum loss exposure for our unconsolidated VIEs were as follows:

				Maximum exposure to
		Asset carrying value		loss (1)

Other-Than-Temporary Impairments

We have a process in place to identify fixed maturity securities that could potentially have an impairment that is other than temporary. Prior to 2018, we also used this process to assess equity securities for impairment. 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.

B-29

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

Each reporting period, all securities are reviewed to determinewhether an other-than-temporary decline in value exists and whether losses should be recognized. We consider relevant facts and circumstances in evaluating whether a credit or interest rate related impairment of a security is other than temporary. Relevant facts and circumstances considered include: (1) the extent and length of time the fair value has been 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; (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 and (6) for equity securities, our ability and intent to hold the security for a period of time that allows for the recovery in value. To the extent we determine a security is deemed to be other than temporarily impaired, an impairment loss is recognized.

The way in which impairment losses on fixed maturities are recognized in the financial statements is dependent on the facts and circumstances related to the specific security. If we intend to sell a security or it is more likely than not that we would be required to sell a security before the recovery of its amortized cost, we recognize an other-than-temporary impairment in net income for the difference between amortized cost and fair value. If we do not expect to recover the amortized cost basis, we do not plan to sell the security and if it is 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 is bifurcated. We recognize the credit loss portion in net income and the noncredit loss portion in OCI (“bifurcated OTTI”). Prior to 2018, impairment losses on equity securities were recognized in net income and were measured as the difference between amortized cost and fair value.

Total other-than-temporary impairment losses, net of recoveries from the sale of previously impaired securities, were as follows:

		For the year ended December 31,
		2019		2018		2017
		(in millions)

Net impairment losses on available-for-sale securities		$	(43.5)	$	(29.1)	$	(79.7)

(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 estimate 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 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.

Of the available-for-sale fixed maturities within our consolidated portfolio in a gross unrealized loss position, 97% were investment grade (rated AAA through BBB-) with an average price of 99 (carrying value/amortized cost) as of December 31, 2019. Gross unrealized losses in our fixed maturities portfolio decreased during the year ended December 31, 2019, primarily due to a decrease in interest rates and 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 882 securities reflecting an average price of 99 as of December 31, 2019. Of this portfolio, 98% was investment grade (rated AAA through BBB-) as of December 31, 2019, with associated unrealized losses of $43.1 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 502 securities reflecting an average price of 98 and an average credit rating of AA+ as of December 31, 2019. Corporate securities with unrealized losses had an average price of 94 and an average credit rating of BBB-. Commercial mortgage-backed securities with unrealized losses had an average price of 95 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, 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 consider these investments to be other-than-temporarily impaired as of December 31, 2019.

Of the available-for-sale fixed maturities within our consolidated portfolio in a gross unrealized loss position, 95% were investment grade (rated AAA through BBB-) with an average price of 97 (carrying value/amortized cost) as of December 31, 2018. Gross unrealized losses in our fixed maturities portfolio increased during the year ended December 31, 2018, primarily due to widening of credit spreads and an increase in interest rates.

For those securities that had been in a continuous unrealized loss position for less than twelve months, our consolidated portfolio held 2,076 securities reflecting an average price of 97 as of December 31, 2018. Of this portfolio, 92% was investment grade (rated AAA through BBB-) as of December 31, 2018, with associated unrealized losses of $473.7 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 2,335 securities reflecting an average price of 96 and an average credit rating of AA- as of December 31, 2018. Corporate securities with unrealized losses had an average price of 95 and an average credit rating of A-. Commercial mortgage-backed securities with unrealized losses had an average price of 96 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, 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 consider these investments to be other-than-temporarily impaired as of December 31, 2018.

Mortgage Loans

Mortgage loans consist of commercial and residential mortgage loans. We evaluate risks inherent in our commercial mortgage loans in two classes: (1) brick and mortar property loans, including mezzanine loans, where we analyze the property's rent payments as support for the loan, and (2) credit tenant loans (“CTL”), where we rely on the credit analysis of the tenant for the repayment of the loan. We evaluate risks inherent in our residential mortgage loan portfolio in two classes: (1) first lien mortgages and (2) home equity mortgages. The carrying amount of our mortgage loan portfolio was as follows:

Mortgage Loan Credit Monitoring

Commercial 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. 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 would 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.

The amortized cost of our commercial mortgage loan portfolio by credit risk, as determined by our internal rating system expressed in terms of an S&P bond equivalent rating, was as follows:

Residential 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.

The amortized cost of our performing and non-performing residential mortgage loans was as follows:

	December 31, 2019
	First liens		Home equity		Total
	(in millions)

Non-performing		2.9		4.3		7.2
Total	$	893.2	$	15.1	$	908.3

Non-Accrual Mortgage Loans

Commercial and residential mortgage loans are placed on non-accrual status if we have concern regarding the collectability of future payments or if a loan 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 of the loan. When a loan 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.

Mortgage Loan Valuation Allowance

We establish a valuation allowance to provide for the risk of credit losses inherent in our portfolio. The valuation allowance includes loan specific reserves for loans that are deemed to be impaired as well as reserves for pools of loans with similar risk characteristics where a property risk or market specific risk has not been identified but for which we anticipate a loss may occur. Mortgage loans on real estate are considered impaired when, based on current information and events, it is probable we will be unable to collect all amounts due according to contractual terms of the loan agreement. When we determine a loan is impaired, a valuation allowance is established equal to the difference between the carrying amount of the mortgage loan and the estimated value reduced by the cost to sell. Estimated value is based on either the present value of the expected future cash flows discounted at the loan's effective interest rate, the loan's observable market price or fair value of the collateral. Subsequent changes in the estimated value are reflected in the valuation allowance. Amounts on loans deemed to be uncollectible are charged off and removed from the valuation allowance. The change in the valuation allowance provision is included in net realized capital gains (losses) on our consolidated statements of operations.

B-37

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

The valuation allowance is maintained at a level believed adequate by management to absorb estimated probable credit losses. 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 loan portfolio, portfolio delinquency information, underwriting standards, peer group information, current economic conditions, loss experience and other relevant factors. The evaluation of our impaired loan component is subjective, as it requires the estimation of timing and amount of future cash flows expected to be received on impaired loans.

We review our commercial mortgage loan portfolio and analyze the need for a valuation allowance for any loan that is delinquent for 60 days or more, in process of foreclosure, restructured, on the internal “watch list” or that currently has a valuation allowance. In addition to establishing allowance levels for specifically identified impaired commercial mortgage loans, management determines an allowance for all other loans in the portfolio for which historical experience and current economic conditions indicate certain losses exist. These loans are segregated 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 environmental factors management believes to be relevant.

For our residential mortgage loan portfolio, we separate the loans into several homogeneous pools, each of which consist of loans of a similar nature including but not limited to loans similar in collateral, term and structure and loan purpose or type. We evaluate loan pools based on aggregated risk ratings, estimated specific loss potential in the different classes of credits, and historical loss experience by pool type. We adjust these quantitative factors for qualitative factors of present conditions. Qualitative factors include items such as economic and business conditions, changes in the portfolio, value of underlying collateral and concentrations. Residential mortgage loan pools exclude loans that have been restructured or impaired, as those loans are evaluated individually.

Impaired Mortgage Loans

Impaired mortgage loans are loans with a related specific valuation allowance, loans whose carrying amount has been reduced to the expected collectible amount because the impairment has been considered other than temporary or a loan modification has been classified as a troubled debt restructuring (“TDR”). 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 of the loan. Our recorded investment in and unpaid principal balance of impaired loans along with the related loan specific allowance for losses, if any, and the average recorded investment and interest income recognized during the time the loans were impaired were as follows:

Mortgage Loan Modifications

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 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 in 2019, 2018 and 2017.

Real Estate

Depreciation expense on invested real estate was $60.3 million, $54.1 million and $55.9 million in 2019, 2018 and 2017, respectively. Accumulated depreciation was $525.9 million and $487.0 million as of December 31, 2019 and 2018, respectively.

Real Estate Transactions

In September 2017, we entered an exchange agreement to exit certain real estate joint ventures. The transaction resulted in us transferring our interest in certain real estate properties in exchange for our joint venture partner’s interest in certain other real estate properties. In a subsequent transaction we sold certain of these real estate properties to a third party. Both transactions closed in September 2017, and resulted in a net pre-tax realized capital gain of $690.9 million (net after-tax realized capital gain of $410.8 million).

Other Investments

Other investments include interests in unconsolidated entities, joint ventures and partnerships and properties owned jointly with venture partners and operated by the partners. Such investments are generally accounted for using the equity method. In applying the equity method, we record our share of income or loss reported by the equity investees in net investment income.

Derivative assets are carried at fair value and reported as a component of other investments. See Note 7, Derivative Financial Instruments, for further details.

Securities Posted as Collateral

As of December 31, 2019 and 2018, we posted $4,062.0 million and $3,761.3 million, respectively, in commercial mortgage loans and residential first lien mortgages to satisfy collateral requirements associated with our obligation under funding agreements with Federal Home Loan Bank of Des Moines (“FHLB Des Moines”). In addition, as of December 31, 2019 and 2018, we posted $2,633.2 million and $2,383.0 million, respectively, in fixed maturities, available-for-sale and trading securities to satisfy collateral requirements primarily associated with a reinsurance arrangement, our derivative credit support annex (collateral) agreements, Futures Commission Merchant (“FCM”) agreements, a lending arrangement and our obligation under funding agreements with FHLB Des Moines. Since we did not relinquish ownership rights on these instruments, they are reported as mortgage loans, fixed maturities, available-for-sale and fixed maturities, trading, respectively, on our consolidated statements of financial position. Of the securities posted as collateral, as of December 31, 2019 and 2018, $163.9 million and $124.2 million, respectively, could be sold or repledged by the secured party.

7. 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 purchase 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 have used exchange‑traded futures to reduce market risks from changes in interest rates and to alter mismatches between the assets in a portfolio and the liabilities supported by those assets.

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 currency swaps 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.

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 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.

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 structured investment relationships with trusts we have determined to be VIEs, which are consolidated in our financial statements. The notes issued by these trusts include obligations to deliver an underlying security to residual interest holders and the obligations contain an embedded derivative of the forecasted transaction to deliver the underlying security.

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 $148.9 million and $88.7 million in cash and securities under collateral arrangements as of December 31, 2019 and December 31, 2018, 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, 2019 and December 31, 2018, was $151.1 million and $108.7 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 triggers, we posted collateral and initial margin of $148.9 million and $88.7 million as of December 31, 2019 and December 31, 2018, 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, 2019, we would be required to post an additional $42.5 million of collateral to our counterparties.

As of December 31, 2019 and December 31, 2018, we had received $156.8 million and $70.1 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, 2019 and December 31, 2018, 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.

	active or discontinued hedging relationships	$	301.3	$	435.9	$	25.8	$	25.7

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 maximum length of time we are hedging our exposure to the variability in future cash flows for forecasted transactions, excluding those related to the payments of variable interest on existing financial assets and liabilities, is 0.5 years. As of December 31, 2019, we had $0.0 million of net gains reported in AOCI on the consolidated statements of financial position related to active hedges of forecasted transactions. If a hedged forecasted transaction is no longer probable of occurring, cash flow hedge accounting is discontinued. If it is probable that the hedged forecasted transaction will not occur, the deferred gain or loss is immediately reclassified from AOCI into net income.

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

We expect to reclassify net gains of $24.3 million from AOCI into net income in the next 12 months, which includes both net deferred gains on discontinued hedges and net losses on periodic settlements of active hedges. Actual amounts may vary from this amount as a result of market conditions.

8. 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, 2019 and 2018, the PDO was $202.7 million and $36.6 million, respectively.

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, 2019 and 2018, $4,010.9 million and $3,512.2 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 December 31, 2019 and 2018, $75.2 million and $109.6 million, respectively, 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, 2019 and 2018, $112.2 million and $114.4 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 December 31, 2019 and 2018, $201.7 million and $201.6 million, respectively, 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.

Additionally, we were authorized to issue up to $9.0 billion of funding agreements under a program that was originally established in March 2004 to support the prospective issuance of medium term notes by unaffiliated entities in both domestic and international markets. Under this program, both the notes and the supporting funding agreements were registered with the United States Securities and Exchange Commission (“SEC”). As of both December 31, 2019 and 2018, $26.2 million of liabilities were being held with respect to issuances outstanding under this program. In contrast with direct funding agreements, GIC issuances and the other three funding agreement backed medium term note programs described above, our payment obligations on each funding agreement issued under this SEC registered program are guaranteed by PFG. We do not anticipate any new issuance activity under this program due to the existence 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. As of December 31, 2019 and 2018, $4,214.3 million and $3,765.3 million, respectively, of liabilities were being held with respect to issuances outstanding under this program. Similar to the SEC registered 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 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,
		2019		2018		2017
		(in millions)
Balance at beginning of year		$	2,252.7	$	2,130.5	$	2,001.3

Net balance at beginning of year			1,848.4		1,754.7		1,661.0

	Current year		1,361.3		1,268.8		1,196.6
	Prior years		0.8		0.3		18.2
Total incurred			1,362.1		1,269.1		1,214.8

Net balance at end of year			1,961.7		1,848.4		1,754.7
Plus: reinsurance recoverable			403.8		404.3		375.8
Balance at end of year		$	2,365.5	$	2,252.7	$	2,130.5
Amounts not included in the rollforward above:
	Claim adjustment expense liabilities	$	57.9	$	54.6	$	50.7

Incurred liability adjustments relating to prior years, which affected current operations during 2019, 2018 and 2017, 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.

Effective income tax rate	11	%	10	%	(30)	%

The U.S. tax reform enacted on December 22, 2017, made broad and complex changes to the U.S. Internal Revenue Code applicable to us. The U.S. statutory tax rate was reduced from 35% to 21% effective January 1, 2018. Other provisions of U.S. tax reform effective January 1, 2018, included, but were not limited to: 1) provisions reducing the dividends received deduction; 2) essentially eliminating U.S. federal income taxes on dividends from foreign subsidiaries; 3) retaining an element of current inclusion of certain earnings of controlled foreign corporations; 4) eliminating the corporate alternative minimum tax (“AMT”); and, 5) changing how existing AMT credits are realized.

Our changes in unrecognized tax benefits were as follows:

		For the year ended December 31,
		2019		2018		2017
		(in millions)
Balance at beginning of period		$	37.2	$	188.5	$	202.6
	Additions based on tax positions related to the current year		0.1		—		7.2
	Additions for tax positions of prior years		23.1		43.1		19.3
	Reductions for tax positions related to the current year		(3.2)		(10.6)		(3.4)
	Reductions for tax positions of prior years		—		(23.2)		(0.5)
	Settlements		—		(160.6)		(36.7)
Balance at end of period (1)		$	57.2	$	37.2	$	188.5

(1) There would be no impact to the effective income tax rate if the 2019 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, 2019, 2018 and 2017, we had recognized $0.8 million, $1.3 million and $125.3 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. Settlement agreements applicable to tax years 1995 to 2003 were executed in 2018 with the Department of Justice, as previously approved by the Joint Committee of Taxation in August 2017. In 2019, an IRS 30-day letter on examination of tax years 2009 through 2012 was received, and the IRS began its examination of tax years 2015 through 2017.

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:

			December 31,
			2019		2018
			(in millions)
Deferred income tax assets:
	Investments, including derivatives		$	190.9	$	122.6
	Insurance liabilities			62.9		—
	Net unrealized losses on available-for-sale securities			—		1.5
	Net operating and capital loss carryforwards			0.1		13.7
	Tax credit carryforwards			106.0		163.2
	Employee benefits			—		10.7
		Total deferred income tax assets		359.9		311.7
Deferred income tax liabilities:
	Deferred acquisition costs			(562.8)		(615.9)
	Investments, including derivatives			(362.0)		(238.3)
	Net unrealized gains on available-for-sale securities			(874.7)		—
	Real estate			(146.7)		(144.5)
	Insurance liabilities			—		(87.9)
	Intangible assets			(9.6)		(7.6)
	Gain on sale of discontinued operations (1)			(203.2)		(209.2)
	Employee benefits			(3.4)		—
	Other deferred income tax liabilities			(21.4)		(37.7)
		Total deferred income tax liabilities		(2,183.8)		(1,341.1)
		Total net deferred income tax liabilities	$	(1,823.9)	$	(1,029.4)

(1) Represents a deferred intercompany gain on the sale of PGI LLC to PFS, which was allocated to stockholder’s equity as the result of a taxable common control transaction on the standalone financials of the transferring entity. 

Our net deferred income taxes by jurisdiction were as follows:

		December 31,
		2019		2018
		(in millions)
Deferred income tax liabilities:
	U.S. federal	$	(1,795.2)	$	(999.1)
	State		(28.7)		(30.3)
Total net deferred income tax liabilities		$	(1,823.9)	$	(1,029.4)

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, 2019 and 2018, we had tax credit carryforwards for U.S. federal income tax purposes of $106.0 million and $163.2 million, respectively. Alternative minimum 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 our consolidated U.S. federal income tax return beginning in 2012 and 2013. The AMT credit carryforwards became refundable in 2018 and will be fully recovered by 2021, and the other tax credits will expire by 2028 if unused. As of December 31, 2019, all accumulated U.S. federal tax credit carryforwards are anticipated to be utilized before expiration; therefore, no valuation allowance has been provided for the related deferred income tax assets.

Notes to Consolidated Financial Statements – (continued)December 31, 2019

As of December 31, 2019 and 2018, domestic state net operating loss carryforwards were $1.0 million and $4.7 million, respectively, and will expire between 2026 and 2036. As of December 31, 2019, 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.

The effects of tax legislation on deferred taxes are recognized in the period of enactment. The primary impact of U.S. tax reform on our 2017 financial results was associated with the effect of reducing the U.S. statutory tax rate from 35% to 21% on our deferred tax balances as of December 31, 2017. The effects of the U.S. tax reform were reflected in the 2017 financial statements as determined or as reasonably estimated provisional amounts based on available information subject to interpretation in accordance with the SEC's Staff Accounting Bulletin No. 118. The provisional amounts apply in regard to potential technical interpretations of accounting and taxing authorities related to elements of the U.S. tax reform subject to change. The provisional amount was finalized within the one-year measurement period with no material adjustments.

Other Tax Information

Income tax returns are filed in the U.S. federal jurisdiction as well as various states and foreign jurisdictions 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 our consolidated U.S. federal income tax returns for years prior to 2009. A settlement was reached in 2018 with the Department of Justice involving a suit in the Court of Federal Claims, requesting refunds for the years 1995-2003. IRS claims for refund for tax years 2004 through 2008, following settlement of a partnership matter with the Department of Justice in March 2019, are expected to be finalized in 2020 following review by the Joint Committee of Taxation. As of December 31, 2019 and 2018, we had $196.6 million and $195.7 million, respectively, of current income tax receivables associated with outstanding audit issues reported as other assets in our consolidated statements of financial position.

PFG filed claims for refund for tax years 2006 through 2008 in 2015 and tax year 2012 in 2016. The IRS commenced audit of our U.S. federal income tax return for 2009 in the fourth quarter of 2011, 2010 in the first quarter of 2012, 2011 in the first quarter of 2013, 2012 in the third quarter of 2015 and 2015 through 2017 in the first quarter of 2019. The U.S. federal statute of limitations expired for years prior to 2009, except for pending audit issues. The statute was extended until December 31, 2020, for 2009 through 2012, has expired for 2013 and 2014, and was extended or remains open for tax years 2015 through 2017 through October 15, 2021. 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 while legal remedies are pursued. Consequently, we do not expect the resolved issues from tax years 1995-2003 or those that might arise in tax years subsequent to 2003 to have a material impact on our net income.

13. 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 post-retirement 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.

Obligations and Funded Status

The combined funded status, reconciled to amounts recognized in the consolidated statements of financial position relating to other postretirement employee benefit (“OPEB”) plan, was as follows:

Other Postretirement Plan Changes and Plan Gains/Losses

For the year ended December 31, 2019, the other postretirement benefit plans had an actuarial loss primarily due to a decrease in the discount rate and a gain from actual and projected medical claims cost being lower than expected. For the year ended December 31, 2018, other postretirement benefit plans had an actuarial gain primarily due to an increase in the discount rate and a gain from actual and projected medical claims cost being lower than expected.

The components of net periodic benefit cost including the service cost component are included in operating expenses on the consolidated statements of operations.

For the other postretirement benefit plans, actuarial gains and losses were amortized with use of the corridors allowed.

For the other postretirement benefit plans, amounts recognized in pre-tax accumulated other comprehensive (income) loss were as follows:

		For the year ended December 31,

Net actuarial (gain) loss and net prior service cost benefit have been recognized in AOCI. The estimated net actuarial (gain) loss and prior service cost (benefit) for the postretirement benefits that will be amortized from AOCI into net periodic benefit cost during the2020 fiscal year are $(0.1) million and $(0.9) million, respectively.

Weighted average assumptions used for other postretirement benefit plans to determine net periodic benefit cost
	For the year ended December 31,
	2019		2018		2017
Discount rate	3.95	%	3.35	%	3.75	%
Expected long-term return on plan assets	5.20	%	4.85	%	4.40	%
Rate of compensation increase	N/A		2.39	%	2.44	%

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 5.20% expected long-term return on plan assets for2019 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, agent medical/life and long-term care plans were 5.25%, 4.95% and 4.35%, respectively.

Assumed Health Care Cost Trend Rates Used to Determine Net Periodic Benefit Cost

	December 31,
	2019		2018
Health care cost trend rate assumed for next year under age 65	6.75	%	7.00	%
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate)	4.50	%	4.50	%
Year that the rate reaches the ultimate trend rate (under age 65)	2029		2026

Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. A one-percentage-point change in assumed health care cost trend rates would have the following effects:

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, investments in equity security portfolios, investments in alternative mutual fund portfolios and investment in a real estate mutual fund. 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. The fair value of the alternative mutual fund portfolios and the real estate mutual fund are based on quoted market prices, which represent the net asset value (“NAV”) of shares held by the other postretirement benefit plan.

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.

(4) The portfolios invest primarily in equities, corporate bonds, foreign currencies, convertible securities and derivatives.

(5) The mutual fund invests primarily in U.S. commercial real estate properties.

As of December 31, 2019 and 2018, $101.8 million and $86.1 million of assets, respectively, in cash, fixed income security portfolios, U.S. equity portfolios and international equity portfolios were included in a trust owned life insurance contract.

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
U.S. equity portfolios	35	%
International equity portfolios	15	%
Fixed income security portfolios	50	%

Estimated Future Benefit Payments

The above table reflects the total estimated future benefits to be paid from the plan, including both our share of the benefit cost and the participants' share of the cost, which is funded by their contributions to the plan. 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, 2019.

14. 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.

Notes to Consolidated Financial Statements – (continued)December 31, 2019

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. 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, 2019, 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.

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, 2019.

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, 2019, was approximately $258.0 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, 2019 and 2018, the liability balance for guaranty fund assessments, which is not discounted, was $21.7 million and $22.2 million, respectively, and was reported within other liabilities 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.

The lease assets and liabilities were as follows:

	December 31, 2019
	(in millions)
Assets
Operating lease assets (1)	$	92.9
Finance lease assets (1)		31.0
Total lease assets	$	123.9
Liabilities
Operating lease liabilities (2)	$	94.0
Finance lease liabilities (2)		31.4
Total lease liabilities	$	125.4

(1) Operating and finance lease assets are primarily reported within property and equipment on the consolidated statements of financial position.

(2) Operating and finance lease liabilities are reported within other liabilities on the consolidated statements of

financial position.

As of December 31, 2018, we had capital lease assets of $31.9 million.

The lease cost was as follows:

		For the year ended
		December 31, 2019
		(in millions)
Finance lease cost (1):
	Amortization of right-of-use assets	$	14.5
	Interest on lease liabilities		1.0
Operating lease cost (1)			29.4
Other lease cost (1) (2)			5.0
Sublease income (3)			(1.7)
Total lease cost		$	48.2

(1) Finance, operating and other lease costs are primarily included in operating expenses on the consolidated statements of operations.

(2) Other lease cost primarily reflects variable and short-term lease costs.

(3) Sublease income is included in fees and other revenues on the consolidated statements of operations.

Dividend Limitations

Under Iowa law, we may pay dividends 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 2019 statutory results, our dividend limitation is approximately $1,060.3 million in ordinary stockholder dividends in 2020 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 2020, some or all of such dividends may be extraordinary and require regulatory approval.

On May 1, 2017, we sold our ownership interest in PGI LLC to PFS in connection with a corporate reorganization designed to better utilize and allocate capital internally. Subsequent to the sale, we paid an extraordinary dividend of $1,068.4 million to PFS with the cash proceeds received from the sale, which was approved by the Commissioner.

16. 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 or disclosed at fair value. 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 during2019.

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, 2019, less than 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.

U.S. Government and Agencies/Non-U.S. Governments. Inputs include recently executed market transactions, interest rate yield curves, maturity dates, market price quotations and credit spreads relating to similar instruments.

States and Political Subdivisions. Inputs include Municipal Securities Rulemaking Board reported trades, U.S. Treasury and other benchmark curves, material event notices, new issue data and obligor credit ratings.

Corporate. Inputs include recently executed transactions, market price quotations, benchmark yields, issuer spreads and observations of equity and credit default swap curves related to the issuer. For private placement corporate securities valued through the matrix valuation approach inputs include the current Treasury curve and risk spreads based on sector, rating and average life of the issuance.

RMBS, CMBS, Collateralized Debt Obligations and Other Debt Obligations. 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 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.

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

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 may utilize the overnight indexed swap (“OIS”) 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 LIBOR interest rate curve to value our positions, which includes a credit spread. This credit spread incorporates an appropriate level of nonperformance risk into our valuations given the current ratings of our counterparties, as well as the collateral agreements in place. Counterparty credit risk is routinely monitored to ensure our adjustment for non-performance 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 non-performance risk on these trades.

Interest Rate Contracts. For non-cleared contracts we use discounted cash flow valuation techniques to determine the fair value of interest rate swaps and swaptions using observable swap curves as the inputs. 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 have interest rate options and have had swaptions that are valued using broker quotes. These are 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. In addition, we have a limited number of non-standard currency swaps that are valued using broker quotes. These are 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 or broker prices to determine the fair value of credit default swaps. These are reflected in Level 3.

Other Investments

Other investments reported at fair value include investment funds reported at fair value, commercial mortgage loans of consolidated VIEs for which the fair value option was elected, equity method real estate investments for which the fair value option was elected and certain redeemable and nonredeemable preferred stock. In addition, in 2017 we had other investment funds 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 (“CCFE”) 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.

B-81

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

Equity method real estate investments for which the fair value option was elected are reflected in Level 3. The equity method real estate investments consist of underlying real estate and debt. The real estate fair value is estimated using a discounted cash flow valuation model that utilizes 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 is estimated using a discounted cash flow analysis based on our incremental borrowing rate for similar borrowing arrangements.

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. In 2018, the fair value of redeemable preferred stock was based on observable inputs and was reflected in Level 2.

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 non-performance 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.

Other Liabilities

Certain obligations reported in other liabilities include embedded derivatives to deliver underlying securities of structured investments to third parties. The fair value of the embedded derivatives is calculated based on the value of the underlying securities that are valued based on prices obtained from third party pricing vendors as utilized and described in our discussion of how fair value is determined for fixed maturities, which are reflected in Level 2.

Certain obligations of consolidated VIEs for which the fair value option was elected were included in other liabilities. The synthetic entity that had these obligations matured in the first quarter of 2017. The VIEs’ unaffiliated obligations were valued utilizing internal pricing models, which were reflected in Level 3.

(2) Within the consolidated statements of financial position, derivative assets are reported with other investments and derivative liabilities are reported with other liabilities. The amounts are presented gross in the tables above to reflect the presentation on the consolidated statements of financial position; however, are presented net for purposes of the rollforward in the Changes in Level 3 Fair Value Measurements tables. Refer to Note 7, Derivative Financial Instruments, for further information on fair value by class of derivative instruments.

(3) 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.

(4)Certain investments are measured at fair value using the NAV per share (or its equivalent) practical expedient and have not been classified in the fair value hierarchy. Other investments using the NAV practical expedient consist of certain fund interests that are restricted until maturity with unfunded commitments totaling $19.9 million and $32.0 million as of December 31, 2019 and December 31, 2018, respectively. Separate account assets using the NAV practical expedient consist of hedge funds with varying investment strategies that also have a variety of redemption terms and conditions. We do not have unfunded commitments associated with these hedge funds.

(1) Both realized gains (losses) and mark-to-market unrealized gains (losses) are generally reported in net realized capital gains (losses) within the consolidated statements of operations. Realized and unrealized gains (losses) on certain securities with an investment objective to realize economic value through mark-to-market changes are reported in net investment income within the consolidated statements of operations.

(2) Gains and losses for separate account assets do not impact net income as the change in value of separate account assets is offset by a change in value of separate account liabilities.

Transfers between fair value hierarchy levels are recognized at the beginning of the reporting period.

Separate account assets transferred from Level 1 to Level 2 during 2018 primarily included cash equivalents as a result of additional analysis to clarify the source of the price. Separate account assets transferred between Level 1 and Level 2 during 2017 primarily related to foreign equity securities. When these securities are valued at the close price of the local exchange where the assets traded, they are reflected in Level 1. When events materially affecting the value occur between the close of the local exchange and the New York Stock Exchange, we use adjusted prices determined by a third party pricing vendor to update the foreign market closing prices and the fair value is reflected in Level 2.

Assets transferred into Level 3 during 2019, 2018 and 2017, 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.

Assets transferred out of Level 3 during 2019, 2018 and 2017, 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.

(1) Represents market comparable interest rate or an index adjusted rate used as the base rate in the discounted cash flow analysis prior to any illiquidity or other adjustments, where applicable.

(2) Revenue multiples are amounts used when we have determined market participants would use such multiples to value the investments.

(3) Represents the range of rate curves used in the valuation analysis that we have determined market participants would use when pricing the instrument. Derived from interpolation between various observable swap rates.

(4) This input factor is the number of contractholders taking withdrawals as well as the amount and timing of the withdrawals and a range does not provide a meaningful presentation.

(5) This input is based on an appropriate industry mortality table and a range does not provide a meaningful presentation.

(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. Increases or decreases in the credit spreads on the comparable assets could cause 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. Increases or decreases in this illiquidity premium could cause 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. Increases or decreases in market volatilities could cause 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. Increases or decreases in risk-free rates could cause the fair value of the embedded derivative to significantly increase or decrease, respectively. Increases or decreases in our own credit risks, which impact the rates used to discount future cash flows, could significantly increase or decrease, respectively, the fair value of the embedded derivative. All of these changes in fair value would impact net income.

Decreases or increases in the mortality rate assumption could cause the fair value of the embedded derivative to decrease or increase, respectively. Decreases or increases in the overall lapse rate assumption could cause 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 could cause 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. Increases or decreases in the assumption of the number of contractholders taking withdrawals could cause the fair value of the embedded derivative to decrease or increase, respectively. Assuming contractholders take withdrawals earlier or later could cause the fair value of the embedded derivative to decrease or increase, respectively. Assuming contractholders take more or less of their benefit could cause 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, 2019, 2018 and 2017.

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. In addition, we had certain obligations of consolidated VIEs held by a synthetic entity for which it was not practicable for us to determine the carrying value. The synthetic entity matured in the first quarter of 2017.

• Certain real estate ventures that are subject to the equity method of accounting because the nature of the investments is to add value to the properties and generate income from the operations of the properties. Other equity method real estate investments are not fair valued because the investments mainly generate income from the operations of the underlying properties.

• In 2017, we had certain investment funds for which we did not have enough influence to account for under the equity method in order to reflect the economics of the investment in the financial statements. We did not elect the fair value option for other similar investments as these investments are generally accounted for under the equity method of accounting.

The following tables present information regarding the assets and liabilities for which the fair value option was elected.

17. 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.

For the years ended, December 31, 2019 and 2018, our use of prescribed statutory accounting practices resulted in higher statutory surplus of $862.1 million and $546.3 million, respectively, relative to the accounting practices and procedures of the NAIC due to its accounting for reserve credits associated with a reinsurance transaction with an affiliated reinsurer. In addition, as of December 31, 2019 and 2018, our permitted statutory accounting practice relating to variable annuities with a guaranteed living benefit rider resulted in lower statutory surplus of $151.3 million and $69.9 million, respectively, relative to carrying certain interest rate swaps at book value rather than fair value, as if they received hedge accounting treatment for statutory. Effective January 1, 2020, the Iowa Insurance Division approved our request to discontinue the use of this permitted practice due to changes in the practices and procedures of the NAIC. The discontinuance of the permitted practice will create a one-time increase to surplus.

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, 2019 and 2018, our affiliated reinsurance subsidiaries assumed statutory reserves of $7,902.3 million and $6,850.3 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, 2019 and 2018, assets admitted under these practices totaled $3,358.0 million and $2,852.0 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, 2019, we met the minimum RBC requirements.

18. Revenues from Contracts with Customers

Administrative Service Fee Revenue

We offer service and trust agreements for defined contribution 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 trust services are also available through an affiliated trust company.

• Fees and other revenues are earned for administrative activities performed for the defined contribution plans including recordkeeping and reporting as well as trust, 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.

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,
		2019		2018		2017

Administrative service fee revenue		$	283.2	$	284.1	$	288.0
Deposit account fee revenue			9.3		10.5		10.2
Commission income			26.9		19.6		14.9
Other fee revenue			2.5		2.3		2.1
	Total revenues from contracts with customers		321.9		316.5		315.2
Fees and other revenues not within the scope of revenue
	recognition guidance (1)		2,074.8		1,905.7		1,866.9
Total fees and other revenues per consolidated statements of
	operations	$	2,396.7	$	2,222.2	$	2,182.1

(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 $42.1 million and $42.5 million as of December 31, 2019 and December 31, 2018, 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, 2019 and 2018, $7.5 million and $8.4 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.

19. Stock‑Based Compensation Plans

As of December 31, 2019, our ultimate parent, PFG, sponsored 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. As of May 20, 2014, no new grants will be made under the Amended and Restated 2010 Stock Incentive Plan. No grants have been made under the Stock Incentive Plan since at least 2005. Under the terms of the 2014 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. The following Stock-Based Compensation Plans information represents all share-based compensation data related to us and our subsidiaries’ employees.

B-98

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

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

	For the year ended December 31,
	2019		2018		2017
	(in millions)
Compensation cost	$	21.9	$	26.4	$	28.4
Related income tax benefit		4.1		5.2		9.8
Capitalized as part of an asset		1.7		1.9		2.5

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	2019			2018			2017
Expected volatility		23.3	%		26.0	%		27.6	%
Expected term (in years)		7.0			7.0			7.0
Risk-free interest rate		2.6	%		2.8	%		2.2	%
Expected dividend yield		4.07	%		3.19	%		2.87	%
Weighted average estimated fair value	$	10.00		$	14.85		$	15.31

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, 2019, we had $1.5 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 2019, 2018 and 2017 was $53.09, $63.98 and $62.78, respectively.

B-99

Principal Life Insurance Company
Notes to Consolidated Financial Statements – (continued)December 31, 2019

As of December 31, 2019, we had $1.9 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 1.6 years.

Restricted Stock Units

Restricted stock units were granted to certain employees and agents under the 2014 Stock Incentive Plan, the Amended and Restated 2010 Stock Incentive Plan and 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 2019, 2018 and 2017 was $53.19, $63.77 and $62.80, respectively.

As of December 31, 2019, we had $18.1 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 had the opportunity to purchase shares of PFG common stock on a semi-annual basis through 2017. Beginning in 2018, participating employees had 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 may 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 is lower.

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 $11.37, $9.27 and $14.72 during 2019, 2018 and 2017, respectively.

Item 28. Indemnification

Sections 490.851 through 490.859 of the Iowa Business Corporation Act permit corporations to indemnify directors and officers where (A) all of the following apply: the director or officer (i) acted in good faith; (ii) reasonably believed that (a) in the case of conduct in the individual's official capacity, that the individual's conduct was in the best interests of the corporation or (b) in all other cases, that the individual's conduct was at least not opposed to the best interests of the corporation; and (iii) in the case of any criminal proceeding, the individual had no reasonable cause to believe the individual's conduct was unlawful; and (B) the individual engaged in conduct for which broader indemnification has been made permissible or obligatory under a provision of the corporation's articles of incorporation.

Unless ordered by a court pursuant to the Iowa Business Corporation Act, a corporation shall not indemnify a director or officer in either of the following circumstances: (A) in connection with a proceeding by or in the right of the corporation, except for reasonable expenses incurred in connection with the proceeding if it is determined that the director has met the relevant standard of conduct (above) or (B) in connection with any proceeding with respect to conduct for which the director was adjudged liable on the basis that the director receive a financial benefit to which he or she was not entitled, whether or not involving action in the director's official capacity.

Registrant's By-Laws provide that it shall indemnify directors and officers against damages, awards, settlements and costs reasonably incurred or imposed in connection with any suit or proceeding to which such person is or may be made a party by reason of being a director or officer of the Registrant. Such rights of indemnification are in addition to any rights to indemnity to which the person may be entitled under Iowa law and are subject to any limitations imposed by the Board of Directors. The Board has provided that certain procedures must be followed for indemnification of officers, and that there is no indemnity of officers when there is a final adjudication of liability based upon acts which constitute gross negligence or willful misconduct.

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Item 29. Principal Underwriters

(a)Other Activity

Principal Securities, Inc. acts as principal underwriter for variable annuity contracts issued by Principal Life Insurance Company Separate Account B, a registered unit investment trust and for variable life insurance contracts issued by Principal Life Insurance Company Variable Life Separate Account, a registered unit investment trust.
