PRUDENTIAL PREMIER VARIABLE ANNUITY B SERIES SM ( B SERIES ) PRUDENTIAL PREMIER VARIABLE ANNUITY L SERIES SM ( L SERIES ) PRUDENTIAL PREMIER VARIABLE ANNUITY X SERIES SM ( X SERIES ) Flexible Premium Deferred Annuities PROSPECTUS: APRIL 30, 2018 PRUCO LIFE INSURANCE COMPANY A Prudential Financial Company 751 Broad Street, Newark, NJ 07102-3777 This prospectus describes three different flexible premium deferred annuity classes issued by Pruco Life Insurance Company ( Pruco Life, we, our, or us ). This prospectus is being provided for informational or educational purposes only and does not take into account the investment objectives or financial situation of any client or prospective clients. The information is not intended as investment advice and is not a recommendation about managing or investing your retirement savings. Clients seeking information regarding their particular investment needs should contact a financial professional. If you are receiving this prospectus, it is because you currently own one of these products. These Annuities are no longer offered for new sales. Each of the B Series, L Series, and X Series is a class within a single annuity contract, rather than a separate annuity contract under State insurance law. For convenience in this prospectus, we sometimes refer to each of these annuity classes as an Annuity, and to the classes collectively as the Annuities. We also sometimes refer to each class by its specific name (e.g., the B Series ). These Annuities were offered as an individual annuity contract or as an interest in a group annuity. Each Annuity has different features and benefits that may be appropriate for you based on your financial situation, your age and how you intend to use the Annuity. This Prospectus describes the important features of the Annuities. The Prospectus also describes differences among the Annuities which include differences in the fees and charges you pay and variations in some product features such as the availability of certain bonus amounts. Each Annuity or certain of its investment options and/or features may not be available in all states. There may also be differences in the compensation paid to your financial professional for each Annuity. Differences in compensation among different annuity products could influence a financial professional s decision as to which annuity to recommend to you. In addition, selling broker-dealer firms through which each Annuity was sold may not make available or may not recommend to their customers certain of the optional features and investment options offered generally under the Annuity. Alternatively, such firms may restrict the optional benefits that they do make available to their customers (e.g., by imposing a lower maximum issue age for certain optional benefits than what is prescribed generally under the Annuity). Selling broker-dealer firms may not recommend all the Annuities and/or benefits described in this prospectus and/or may impose restrictions on the availability of the Annuity based on certain criteria. Please speak to your financial professional for further details. The guarantees provided by the variable annuity contracts and the optional benefits are the obligations of and subject to the claims paying ability of Pruco Life. Certain terms are capitalized in this Prospectus. Those terms are either defined in the Glossary of Terms or in the context of the particular section. Because the X Series Annuity grants Credits with respect to your purchase payments, the expenses of the X Series Annuity may be higher than expenses for an Annuity without a credit. In addition, the amount of the Credits that you receive under the X Series Annuity may be more than offset over time by the additional fees and charges associated with the Credit. THE SUB-ACCOUNTS Each Sub-account of the Pruco Life Flexible Premium Variable Annuity Account invests in an underlying mutual fund portfolio. The Pruco Life Flexible Premium Variable Annuity Account is a separate account of Pruco Life, and is the investment vehicle in which your Purchase Payments are held. Currently, portfolios of Advanced Series Trust and ProFunds VP are being offered. See the following page for a complete list of Subaccounts. Certain Sub-accounts are not available if you participate in an optional living benefit see Stipulated Investment Options if you Elect Certain Optional Benefits later in this prospectus for details. PLEASE READ THIS PROSPECTUS Please read this Prospectus and the current prospectuses for the underlying mutual funds. Keep them for future reference.

GLOSSARY OF TERMS Many terms used within this Prospectus are described within the text where they appear. The description of those terms are not repeated in this Glossary of Terms. Account Value: The value of each allocation to a Sub-account (also referred to as a variable investment option ) plus any Fixed Rate Option prior to the Annuity Date, increased by any earnings, and/or less any losses, distributions and charges. The Account Value is calculated before we assess any applicable Contingent Deferred Sales Charge ( CDSC or surrender charge ) and/or, unless the Account Value is being calculated on an Annuity anniversary, any fee that is deducted from the Annuity annually in arrears. The Account Value is determined separately for each Sub-account and for each Fixed Rate Option, and then totaled to determine the Account Value for your entire Annuity. With respect to the X Series, the Account Value includes any Longevity Credit we apply and includes any Purchase Credits we applied to your purchase payments that we are entitled to recover under certain circumstances. With respect to Annuities with a Highest Daily Lifetime Five Income Benefit election, Account Value includes the value of any allocation to the Benefit Fixed Rate Account. Adjusted Purchase Payments: As used in the discussion of certain optional benefits in this prospectus and elsewhere, Adjusted Purchase Payments are purchase payments, increased by any Credits applied to your Account Value in relation to such purchase payments, and decreased by any charges deducted from such purchase payments. Annual Income Amount: This is the annual amount of income for which you are eligible for life under the optional benefits. Annuitization: The application of Account Value to one of the available annuity options for the Owner to begin receiving periodic payments for life (or joint lives), for a guaranteed minimum number of payments or for life with a guaranteed minimum number of payments. Annuity Date: The date you choose for annuity payments to commence. Unless we agree otherwise, the Annuity Date must be no later than the first day of the calendar month coinciding with or next following the 95th birthday of the older of the Owner or Annuitant. Annuity Year: A 12-month period commencing on the Issue Date of the Annuity and each successive 12-month period thereafter. Beneficiary Annuity: If you are a beneficiary of an Annuity that was owned by a decedent, subject to the requirements discussed in this Prospectus, you may transfer the proceeds of the decedent s annuity into one of the Annuities described in this prospectus and continue receiving the distributions that are required by the tax laws. This transfer option is only available for purchase of an IRA, Roth IRA, or a nonqualified annuity. Benefit Fixed Rate Account: A Fixed Rate option offered as part of this Annuity that is used only if you have elected the optional Highest Daily Lifetime Five Income Benefit. Amounts allocated to the Benefit Fixed Rate Account earn a fixed rate of interest, and are held within our general account. You may not allocate purchase payments to the Benefit Fixed Rate Account. Rather, Account Value is transferred to and from the Benefit Fixed Rate Account only under the pre-determined mathematical formula of the Highest Daily Lifetime Five Income Benefit. Code: The Internal Revenue Code of 1986, as amended from time to time. Combination 5% Roll-Up and HAV Death Benefit: We offer an optional Death Benefit that, for an additional cost, provides an enhanced level of protection for your beneficiary(ies) by providing the greater of the Highest Anniversary Value Death Benefit and a 5% annual increase on purchase payments adjusted for withdrawals. Contingent Deferred Sales Charge ( CDSC ): This is a sales charge that may be deducted when you make a full or partial withdrawal under your Annuity. We refer to this as a contingent charge because it can be imposed only if you make a withdrawal. The charge is a percentage of each applicable Purchase Payment that is being withdrawn. The period during which a particular percentage applies is measured from the effective date of each Purchase Payment. The amount and duration of the CDSC varies among the X Series, L Series, and B Series. See Summary of Contract Fees and Charges for details on the CDSC for each Annuity. DCA Fixed Rate Option: An investment option that offers a fixed rate of interest for a specified period during the accumulation period. The DCA Fixed Rate Option is used only with our 6 or 12 Month Dollar Cost Averaging Program ( 6 or 12 Month DCA Program ), under which the Purchase Payments that you have allocated to that DCA Fixed Rate Option are transferred to the designated Sub-accounts over a 6 month or 12 month period. We no longer offer our 6 or 12 Month DCA Program. Excess Income: All or a portion of a Lifetime Withdrawal that exceeds the Annual Income Amount for that benefit year is considered excess income ( Excess Income ). Each withdrawal of Excess Income proportionally reduces the Annual Income Amount for future benefit years. Fixed Rate Option: An investment option that offers a fixed rate of interest for a specified Guarantee Period during the accumulation period. Free Look: Under state insurance laws, you have the right, during a limited period of time, to examine your Annuity and decide if you want to keep it or cancel it. This right is referred to as your Free Look right. The length of this time period depends on the law of your state, and may vary depending on whether your purchase is a replacement or not. Good Order: An instruction received by us, utilizing such forms, signatures, and dating as we require, which is sufficiently complete and clear that we do not need to exercise any discretion to follow such instructions. In your Annuity contract, we may use the term In Writing to refer to this general requirement. Guaranteed Minimum Income Benefit (GMIB): An optional benefit that, for an additional cost, after a seven-year waiting period, guarantees 1

your ability to begin receiving income from your Annuity in the form of annuity payments based on your total purchase payments and an annual increase of 5% on such purchase payments adjusted for withdrawals (called the Protected Income Value ), regardless of the impact of market performance on your Account Value. We no longer offer GMIB. Guarantee Period: A period of time during the accumulation period where we credit a fixed rate of interest on a Fixed Rate Option. Highest Daily Guaranteed Return Option (Highest Daily GRO)/Highest Daily Guaranteed Return Option (HD GRO II): Highest Daily GRO and HD GRO II are separate optional benefits that, for an additional cost, guarantee a minimum Account Value at one or more future dates and that requires your participation in a program that may transfer your Account Value according to a predetermined mathematical formula.

We no longer offer Lifetime Five. Owner: With an Annuity issued as an individual annuity contract, the Owner is either an eligible entity or person named as having ownership rights in relation to the Annuity. With an Annuity issued as a certificate under a group annuity contract, the Owner refers to the person or entity who has the rights and benefits designated as to the Participant in the certificate. Service Office: The place to which all requests and payments regarding an Annuity are to be sent. We may change the address of the Service Office at any time.
