PROPOSAL 1 –— APPROVE CHANGINGTHE RECLASSIFICATION OF THE PORTFOLIO’S INVESTMENT OBJECTIVEDIVERSIFICATION STATUS FROM DIVERSIFIED TONON-DIVERSIFIED

IntroductionIf the Proposal is approved at the Meeting, the Portfolio would no longer be subject to the following fundamental investment restriction:

The Portfolio will not, with respect to 75% of its total assets, purchase securities of an issuer (other than the U.S. Government, its agencies, instrumentalities or authorities or repurchase agreements fully collateralized by U.S. Government securities, and other investment companies) if (a) such purchase would, at the time, cause more than 5% of the Portfolio’s total assets taken at market value to be invested in the securities of such issuer; or (b) such purchase would, at the time, result in more than 10% of the outstanding voting securities of such issuer being held by the Portfolio.

Section 5(b) of the 1940 Act requires mutual funds to be classified as either diversified ornon-diversified, and a fund’s diversification status is considered a fundamental policy that cannot be changed without Shareholder approval. Diversified funds are subject to the restrictions included in the above policy andnon-diversified funds are not. As a result, anon-diversified fund is permitted to hold a greater percentage of its assets in the securities of a single issuer. In addition, anon-diversified fund is permitted to operate as a diversified fund, but a diversified fund cannot becomenon-diversified unless Shareholders approve the change.

The Portfolio is anopen-end management investment company (i.e.,has been constrained by operating as a mutual fund), which is registered under the Investment Company Actdiversified fund since securities of 1940 (the “Act”). Under the Act and related regulations, a mutual fund must disclose its investment objective in its registration statement filed with the Securities and Exchange Commission (the “SEC”). The Portfolio’s investment objective currently is:

Thrivent Bond Index Portfolio strives for investment results similar to the total return of the Barclays U.S. Aggregate Bond Index.

This investment objective currently is considered a “fundamental” investment policy, which means that, under the Act, it may be changed only if approved by a majoritycertain issuers represent greater than 5% of the Portfolio’s shareholders. Thisindex, the S&P 500 Growth Index (the “Index”), and securities of other issuers are just below 5%. Being classified as a diversified fund has made it more difficult for the Portfolio to achieve targeted weightings with respect to these holdings because of the 5% limitation. The proposed change to the diversification policy could allow the Portfolio to more effectively implement its investment strategy due to greater flexibility to hold larger positions without substantially impacting its portfolio management process.

If the proposal is approved at the Meeting, the Portfolio would continue to changebe subject to diversification tests under Subchapter M of the Internal Revenue Code that apply to regulated investment companies. To qualify, among other requirements, the Portfolio must limit its investment so that, at the close of each quarter of the taxable year, (1) not more than 25% of the Portfolio’s investment objective to:

Thrivent Government Bond Portfolio seeks total return, consistentassets will be invested in the securities of a single issuer, and (2) with preservationrespect to 50% of capital.

In seeking to achieve its new investment objective,total assets, not more than 5% of its total assets will be invested in the securities of a single issuer and the Portfolio will under normal circumstances, invest at least 80% of its net assets (plus the amount of borrowings for investment purposes) in U.S. government bonds. For purposes of this disclosure, “U.S. government bonds” are debt instruments issued or guaranteed by the U.S. government or its agencies and instrumentalities, including Treasury Inflation Protected Securities (TIPS) and mortgage-backed securities issued or guaranteed by the Government National Mortgage Association (GNMA or Ginnie Mae), the Federal National Mortgage Association (FNMA or Fannie Mae) or the Federal Home Loan Mortgage Corporation (FHLMC or Freddie Mac). Currently, under normal circumstances, the Portfolio invests at least 80% of net assets (plus the amount of any borrowing for investment purposes) in a representative sample of investment-grade bonds and other debt securities included in the Barclays U.S. Aggregate Bond Index. Accordingly, the Portfolio currently invests in government bonds, asset- and mortgage-backed securities, and corporate bonds from a broad range of industries.

If the change to the investment objective is approved by shareholders, Thrivent Financial will make certain other significant changes to the Portfolio that shareholders are not being asked to vote on. The significant changes would include changes to the principal investment strategies and changing the Portfolio’s name. These changes areown more fully described in the “Other Proposed Changes to the Portfolio” section below.

Thrivent Financial’s Recommendation and Board of Directors’ Action

At a meetingthan 10% of the Fund’s Board held on May 24, 2017, Thrivent Financial recommended that the Board approve changing the Portfolio’s investment objective – subject to shareholder approval – and corresponding changes to the Portfolio’s name and principal investment strategies.outstanding voting securities of a single issuer.

3

Thrivent Financial believes that the proposed change to the investment objective, together with the proposed changes to the investment strategies, would enable the Portfolio to offer more yield and higher risk-adjusted returns, but with a similar duration and no corporate credit risk. In addition, Thrivent Financial believes the Portfolio would be better positioned to take advantage of the anticipated continuation of the overall bond market becoming more heavily weighted to U.S. Treasuries. Thrivent Financial also believes that index investing is not the most compelling way to invest in fixed income securities because a bond index will have its largest weightings in the most heavily indebted issuers.

After extensively discussing Thrivent Financial’s recommended changes to the Portfolio, the Board unanimously approved the proposed changes. In approving the changes, the Board took the following factors into account, among others:

4

The Board was advised and assisted by counsel to the Independent Directors. No single factor or group of factors was deemed to be determinative by the Board in approving the proposed changes. Instead, the Board based its decision on the totality of the information that it reviewed.

Other Proposed Changes to the Portfolio

Principal Investment Strategies. If the change to the Portfolio’s investment objective is approved, the Portfolio’s principal strategies also will change. For ease of comparison, the following chart shows the Portfolio’s current principal strategies next to the proposed principal strategies:

5

If the change to the Portfolio’s investment objective is approved, the Portfolio will employ an active management strategy, rather than a passive strategy that seeks to track an index. The primary changes to the composition of the Portfolio would include eliminating its allocation to corporate bonds and significantly increasing the Portfolio’s allocation to securitized assets (e.g., asset- and mortgage-backed securities and agency commercial mortgage-backed securities). The Portfolio will incur transaction costs when it changes its composition.

Portfolio’s Name. In connection with the principal investment strategies changes, the Portfolio would change its name to Thrivent Government Bond Portfolio.

Principal Risks. If the principal investment strategies are changed as described above, the Portfolio will continue to be subject to some of the same principal risks, including: interest rate risk, investment adviser risk, market risk, mortgage-related and other asset-backed securities risk, liquidity risk, and portfolio turnover rate risk. The Portfolio will also be subject to the following additional principal risks:

6

There can also be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. The Portfolio’s investments in inflation-linked securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation index. In addition, inflation-linked securities are subject to the risk that the Consumer Price Index for All Urban Consumers(CPI-U) or other relevant pricing index may be discontinued, fundamentally altered in a manner materially adverse to the interests of an investor in the securities, altered by legislation or Executive Order in a materially adverse manner to the interests of an investor in the securities or substituted with an alternative index.

Portfolio Managers. Currently, Michael G. Landreville, CFA, CPA (inactive) serves as portfolio manager of the Portfolio. If the change to the investment objective is approved and the aforementioned investment strategy changes are implemented, Gregory R. Anderson, CFA will join Mr. Landreville as portfolio manager of the Portfolio. Mr. Anderson has been with Thrivent Financial since 1997 and has served as a portfolio manager since 2000.

Effect if Shareholders do not Approve the Change toReclassification of the Portfolio’s Investment ObjectiveDiversification Status from Diversified toNon-Diversified

If shareholders do not approve the change toreclassification of the Portfolio’s investment objective, the Portfolio’s current investment objective will stay the same, the other proposed changes described above willdiversification status from diversified tonon-diversified is not be made, andapproved, the Portfolio will continue to be operated in its current form.operate as a diversified fund. However, in the future, the Board may take such actions as it deems to be in the best interests of the Portfolio and its shareholders, such as considering proposing the reorganization of the Portfolio into another portfolio.

The Board recommends that you vote “FOR” the proposed change to the Portfolio’s investment objective.

7

PROPOSAL 2 – APPROVE THE CONVERSION OF THE PORTFOLIO’S INVESTMENT OBJECTIVE FROM FUNDAMENTAL TONON-FUNDAMENTAL

The Portfolio’s investment objective currently is described in the prospectus as a “fundamental” investment policy, which means that, under the Act, the Portfolio’s investment objective may be changed only if approved by a majority of the Portfolio’s shareholders. If approved by shareholders, the Portfolio’s investment objective would change from fundamental tonon-fundamental, which would give the Board additional flexibility to make any changes to the Portfolio’s investment objective, with advance notice to shareholders, that it deems appropriate in the future to address changing market conditions or other developments, while saving the Portfolio’s shareholders the potential cost and delay of a proxy solicitation.

If shareholders approve the conversion of the Portfolio’s investment objective from fundamental tonon-fundamental, the Board may change the Portfolio’s investment objective with advance notice to shareholders. Shareholders will not be required to approve future changes to the Portfolio’s investment objective.

This Proposal 2 relates only to the Portfolio’s investment objective.

Effect if Shareholders do not Approve the Conversion of the Portfolio’s Investment Objective from “Fundamental” to“Non-Fundamental”

If the conversion of the Portfolio’s investment objective from fundamental tonon-fundamental is not approved, the Portfolio’s investment objective will continue to be fundamental, and shareholders will be required to approve future changes to the Portfolio’s investment objective.Shareholders.

ADDITIONAL INFORMATION ABOUT THE PORTFOLIO

Shareholder Information

At the close of business on the Record Date, the Portfolio had outstanding 18,252,740[                ] shares. As of the Record Date, the directorsDirectors and officers of the Portfolio as a group owned less than 1% of the shares of the outstanding shares of the Portfolio. As of the Record Date, no person was known by the Portfolio to own beneficially or of record as much as 5% of the Portfolio shares except as follows:

Under the 1940 Act, any person who owns more than 25 percent of the voting securities of another company is presumed to control such company.

The Separate Accounts and the Retirement Plans

Shares in the Portfolio are currently sold, without sales charges, only to: (1) separate accounts of Thrivent Financial and Thrivent Life, Insurance Company (“Thrivent Life”), a subsidiary of Thrivent Financial, which are used to fund benefits of variable life insurance and variable annuity contracts (each a “variable contract”) issued by Thrivent Financial and Thrivent Life; and (2) other portfolios of Thrivent Series Fund. Effective June 30, 2019, it is expected that Thrivent Life will be dissolved and the contract obligations of Thrivent Life will be assumed by Thrivent Financial.

A Prospectus for the variable contract describes how the premiums and the assets relating to the variable contract may be allocated among one or more of the subaccounts that correspond to the portfolios of Thrivent Series Fund.

Thrivent SeriesThe Fund serves as the underlying investment vehicle for variable annuity contracts and variable life insurance policies that are funded through separate accounts established by Thrivent Financial. It is possible that in the future, it may not be advantageous for variable life insurance separate accounts and variable annuity separate accounts to invest in the portfolios at the same time. Although neither Thrivent Financial nor Thrivent Seriesthe Fund currently foresees any such disadvantage, the Board monitors events in order to identify any material conflicts between such policy owners and contract owners. Material conflict could result from, for example, (1) changes in state insurance laws, (2) changes in federal income tax law, (3) changes in the investment management of a portfolio, or (4) differences in voting instructions between those given by policy owners and those given by contract owners. Should it be necessary, the Board would determine what action if any, should be taken on response to any such conflicts.

95

As a result of differences in tax treatment and other considerations, a conflict could arise between the interests of the variable life insurance contract owners and variable annuity contract owners, and plan participants with respect to their investments in Thrivent Series Fund.owners. The Board will monitor events in order to identify the existence of any material irreconcilable conflicts and to determine what action if any, should be taken in response to any such conflicts.

If reasonable procedures are employed, the Portfolio will not be liable for following Internet or telephone votes which it believes to be genuine.

11
