PROPOSAL I

APPROVAL OF A PLAN OF LIQUIDATION

At a meeting held on October 2, 2007, the Board, upon the recommendation of the Fund’s investment adviser, Transamerica Fund Advisors, Inc. (“TFAI”), determined that it would be in the best interests of the Fund and the Fund’s shareholders to liquidate and dissolve the Fund. The Board and TFAI reached this decision primarily for two reasons: (1) Gateway Investment Advisers, L.P. (“Gateway”), the Fund’s sub-adviser, notified the Board and TFAI that it intends to resign as sub-adviser of the Fund effective December 3, 2007, and no replacement to Gateway has been found; and (2) the Fund is not economically viable at its current asset level, and the asset level is expected to decline further.

After consideration of the Fund’s prospects and possible alternatives to dissolution, upon recommendation of TFAI and the management of TA IDEX, the Board, including all of the Trustees who are not “interested persons” (for regulatory purposes) of TA IDEX or TFAI (the “Independent Trustees”), reviewed and approved the proposed liquidation and dissolution of the Fund pursuant to a Plan of Liquidation and Dissolution (the “Plan”). The Plan provides for the liquidation of the Fund’s assets and the distribution to its shareholders of all of the proceeds of the liquidation. If Proposal I is approved by the shareholders of the Fund, the net proceeds (after deduction for amounts estimated to be necessary to satisfy the debts and liabilities of the Fund) will be paid to shareholders pro rata, in cash or cash equivalents or in-kind, on or about November 29, 2007.

Shareholder approval of the Fund’s liquidation and dissolution is requested. For the reasons set forth below, the Board recommends that the shareholders of the Fund vote in favor of Proposal I. If the Fund’s shareholders do not approve the Plan, the Fund will continue to exist in accordance with its stated objective and policies. In such a case, the Board would consider what, if any, steps to take

concerning the future of the Fund (which could include liquidation of the Fund without obtaining shareholder approval, as permitted by the Fund’s organizational documents).

Shareholders are free to redeem their shares prior to the date on which the Fund is proposed to be liquidated, and they may exchange their Fund shares for shares offered by another TA IDEX series without incurring any fees.

Reasons for Liquidation and Dissolution

The liquidation and dissolution of the Fund is recommended for the following reasons, among others:

	•		The Fund offers a “guarantee” feature, pursuant to which TFAI, the Fund’s investment adviser, guarantees that shareholders will receive the higher of the amount of the principal they initially invested in the Fund five years after the investment date (the “guarantee period”) or the value of their investment based on the performance of the Fund over the guarantee period. At the end of a guarantee period, the Fund redeems the entirety of the investments covered under the guarantee period to the applicable shareholders. The Fund offered three successive guarantee periods on July 1, 2002, 2003 and 2004. The Fund’s first guarantee period matured on July 2, 2007. As a result of the redemption of investments covered in the first guarantee period, which included most of the Fund’s assets, the Fund’s assets were significantly reduced. As of September 13, 2007, the Fund had approximately $11 million in assets. It is anticipated that asset levels will continue to significantly decrease each time a guarantee period matures. In addition, as a result of the Fund’s “guarantee” feature, the Fund is closed to new investment, which significantly limits its ability to increase or maintain its size.
	•		Gateway, the Fund’s investment sub-adviser, invests the assets of the Fund primarily in the 500 stocks included in the Standard & Poor’s 500 Composite Stock Price Index and in virtually the same proportion as the index. Gateway then writes call options on the index. Gateway informed the Board and TFAI that it is increasingly challenging to manage the Fund according to its investment objective and strategies due to the current low level of assets in the Fund. For example, it is increasingly difficult to acquire all the stocks included in the Fund’s index. As a result, Gateway notified TFAI that it no longer intends to serve as investment sub-adviser to the Fund, effective December 3, 2007.
	•		The Fund is too small to generate investment sub-adviser interest. As a result, TFAI has been unable to find a viable replacement to Gateway.
	•		As a result of the Fund’s small asset size and inability to significantly increase its asset levels, the Fund has high expense ratios. As a result, TFAI has advised the Board that it believes the Fund currently suffers diseconomies of scale, and investors in the Fund are unlikely to benefit from economies of scale and realize lower expense ratios. Further, Fund management has determined that the Fund does not significantly add to management’s long-term strategy of building a diversified, competitive fund family.

The officers of TA IDEX considered alternatives to the Fund’s liquidation. Among other things, they sought to determine whether hiring a new sub-adviser with investment experience and expertise similar to Gateway could be a viable option or if a merger or transfer of assets with another investment company would be possible, and if so, whether it would produce desirable results for shareholders. Management reviewed current market conditions; the similarities and differences between the Fund and other funds managed by TFAI and other investment sub-advisers; the unique “guarantee” feature of the Fund; the relatively small size of the Fund; the time, effort and expense required to effect a transaction; and the implications for shareholders of such a transaction. The officers determined that there was neither a suitable sub-adviser to replace Gateway nor any affiliated fund with which the Fund could be combined without significant changes in the Fund’s portfolio, including liquidation of significant portions of its portfolio.

They also determined that the expense of a merger or transfer of the assets to another investment company likely would be greater than any benefits shareholders of the Fund could expect to realize from such a transaction. The officers also investigated the relative costs involved in the liquidation and dissolution of the Fund. Following these considerations, the officers of TA IDEX decided to recommend to the Board the Fund’s liquidation and dissolution.

Terms of the Plan

Following are some of the key terms of the Plan, which is attached as Appendix A to this Proxy Statement and qualifies the following summary in its entirety.

•

Effective Date of the Plan and Liquidation of the Fund’s Assets. The Plan shall become effective with respect to the Fund on the date of its adoption and approval by the shareholders of the Fund. Following this approval, the Fund: (i) will cease to invest its assets in accordance with its investment objective and will sell any portfolio securities it owns in order to convert its assets to cash or cash equivalents, or, if determined to be in the best interest of the Fund and the Fund shareholders, elect not to liquidate certain assets but rather distribute them in-kind to its shareholders, to the extent authorized by law; (ii) will not engage in any business activities except for the purposes of winding up its business and affairs, marshalling and preserving the value of its assets and distributing its assets to shareholders after the payment to (or reservation of assets for payment to) all creditors; and (iii) will be dissolved in accordance with the laws of the State of Delaware and the Fund’s Declaration of Trust. The Fund may begin to liquidate some or all of its portfolio prior to the Special Meeting in order to meet redemption requests or in anticipation of liquidation.

•

Liquidating Distribution. On or about November 29, 2007 or as soon as practical thereafter, TA IDEX on behalf of the Fund will mail the following to each shareholder of record of the liquidating Fund on that date: (i) a liquidating distribution, which may be in cash or cash equivalents or in-kind, equal to the shareholder’s proportionate interest in the net assets of the Fund (after giving effect to amounts considered necessary to satisfy the Fund’s liabilities); and (ii) information concerning the sources of the liquidating distribution.

•

Cessation of Rights of Shareholders. As a result of the liquidating distribution for the Fund, shares of the Fund will no longer be deemed outstanding as of such time and will be deemed cancelled.

•

Expenses. TFAI and/or its affiliates will bear all expenses incurred by it in carrying out of the Plan, including but not limited to, all printing, legal, accounting, custodian and transfer agency fees, and the expenses of any reports to or meeting of shareholders. Any expenses and liabilities attributed to the Fund subsequent to the mailing of the liquidating distribution and for which a reserve has not been established will be borne by TFAI and/or its affiliates.

•

Implementation. The Plan provides that the Trustees and officers of TA IDEX may take such actions as are necessary to effectuate the Plan, and that the Trustees shall have the authority to authorize such amendments of the provisions of the Plan as may be necessary or appropriate to marshal the assets of the Fund and to effect the dissolution, complete liquidation and termination of the existence of the Fund and the purposes to be accomplished by the Plan.

Material Federal Income Tax Consequences

Each shareholder who receives a liquidating distribution will recognize gain (or loss) for federal income tax purposes equal to the amount by which the distribution exceeds (or is less than) the shareholder’s tax basis in his or her Fund shares. Assuming that the shareholder holds such shares as capital assets, such gain or loss generally will be treated as long-term capital gain or loss if the shares were held for more than one year and otherwise generally will be treated as short-term capital gain or loss.

It is expected that, prior to the liquidating distribution, the Fund will distribute any previously undistributed net income or net capital gains. Such distribution would be taxed as ordinary income to the extent that it is derived from net income or net short-term capital gains and will be generally be taxed as long-term capital gain to the extent that it is derived from net long-term capital gains.

Notwithstanding the foregoing, any loss realized by a shareholder in respect of his or her Fund shares with a tax holding period of six months or less will be treated as long-term capital loss to the extent of any capital gain dividends with respect to such shares. The federal income tax treatment that a Fund shareholder would receive if such shareholder’s entire interest in the Fund were redeemed prior to the liquidation generally would be identical to the federal income tax treatment described above to a shareholder in liquidation of the shareholder’s interest in the Fund.

The tax consequences discussed herein may affect shareholders differently depending upon their particular tax situations unrelated to the liquidating distribution, and accordingly, this summary is not a substitute for careful tax planning on an individual basis. Shareholders may wish to consult their personal tax advisers concerning their particular tax situations and the impact thereon of receiving the liquidating distribution as discussed herein, including any state, local and foreign tax consequences.

The Fund anticipates that it will retain its qualification as a regulated investment company under the Internal Revenue Code, as amended, (the “Code”) during the liquidation period and, therefore, will not be taxed on any of its net income from the sale of its assets.

Other Information

Prior to the proposed liquidation and dissolution of the Fund, Fund shareholders may wish to invest in other TA IDEX series. Class A, B and C shareholders may exchange their Fund shares for shares of the same class offered by another TA IDEX series without incurring any sales charge, and Class M shareholders are able to purchase Class A shares of other TA IDEX series with their Class M redemption proceeds without paying a sales charge. Upon consummation of the liquidation and dissolution, Fund shareholders will be able to direct the re-investment of the proceeds of the liquidation in the same class of shares of another TA IDEX series without paying any sales charges. Investors should consult the prospectuses of the other TA IDEX series in which they wish to invest prior to making their decision.

Fund shareholders who currently hold shares through tax-deferred accounts with TA IDEX such as, without limitation, retirement plans described in Section 403(b) and 408 (IRAs) of the Code and Coverdell ESA, can continue to maintain their accounts by investing into another TA IDEX series as discussed in the preceding paragraph. If they do not intend to maintain their accounts with TA IDEX, they may need to establish a similar tax-deferred account with another institution and submit instructions accordingly. If such shareholders do not provide specific re-investment instructions prior to the consummation of the liquidation and dissolution of the Fund and if their account documents do not specify how the proceeds from the liquidation must be re-invested, the proceeds from the liquidation will be automatically re-invested in the corresponding class of shares (or Class A shares if they hold Class M shares of the Fund) of TA IDEX Transamerica Money Market, another TA IDEX series, as a temporary investment pending specific instructions from the shareholders to avoid

unintended tax consequences from a payment of the proceeds of the liquidation directly to the shareholders. Such fund shareholders who currently hold shares through tax-deferred accounts and who do not provide specific instructions prior to the consummation of the liquidation and dissolution of the Fund, and whose account documents do not specify how the proceeds from the liquidation must be re-invested, will be deemed to have consented to this temporary re-investment in TA IDEX Transamerica Money Market pending further instructions.

Evaluation by the Board

At a meeting held on October 2, 2007, the Board carefully considered whether it was appropriate to approve the Plan and recommend that Fund shareholders approve the Plan. The Board requested information, provided by TFAI, that it believed to be reasonably necessary to reach its conclusion. The Board carefully evaluated this information, and was advised by Fund counsel and independent legal counsel during its deliberations. After review, the Trustees determined that the Plan is in the best interests of the Fund and its shareholders. Accordingly, the Trustees, including the Independent Trustees, approved the Plan and authorized its submission to the Fund’s shareholders for their approval. The Trustees recommended that the Fund’s shareholders approve the Plan on the basis of the following considerations, among others:

•

Gateway, the Fund’s sub-adviser, intends to resign as sub-adviser of the Fund and no appropriate replacement has been identified;

•

The size of the Fund makes it increasingly challenging for Gateway to pursue the Fund’s investment objective and strategies;

•

The size of the Fund is modest, leaving the Fund too small to be economically viable and there is limited opportunity to increase the size of the Fund and achieve economies of scale;

•

The Fund’s operating expenses are relatively high;

•

The guarantee feature of the Fund has an impact on the Fund’s expense ratios and performance;

•

The performance results of the Fund since its inception are positive;

•

Possible alternatives to liquidation, including the merger of the Fund into another mutual fund, are not practical in the current circumstances and may not be advantageous to the Fund or its shareholders; and

•

Class A, B and C shareholders may exchange their Fund shares for shares offered by another TA IDEX series without incurring any fee, and Class M shareholders are able to purchase Class A shares of other TA IDEX series with their Class M redemption proceeds without paying a sales charge.

Based upon its review, the Board determined that the Plan is in the best interests of the Fund and its shareholders. Accordingly, after consideration of the above factors, and such other information it considered relevant, the Board voted to recommend approval of the Plan by the Fund’s shareholders.

THE BOARD, INCLUDING THE INDEPENDENT TRUSTEES, RECOMMENDS THAT SHAREHOLDERS OF THE FUND VOTE “FOR” APPROVAL OF THE PLAN AS PROVIDED UNDER THIS PROPOSAL. UNMARKED PROXIES WILL BE SO VOTED.

OTHER BUSINESS

The Trustees do not know of any matters to be presented at the Special Meeting other than those set forth in this Proxy Statement. If other business should properly come before the Special Meeting, Proxies will be voted in accordance with the judgment of the persons named in the accompanying Proxy.

The costs of the Special Meeting, including the preparation and mailing of the Notice, Proxy Statement and Proxy, and the solicitation of Proxies, including reimbursements to broker-dealers and others who forwarded proxy materials to their clients will be paid by TFAI and/or its affiliates.

Shareholder Voting. Shareholders of record of the Fund who own shares of beneficial interest at the close of business on the Record Date will be entitled to notice of, and to vote at, the Special Meeting. Shareholders are entitled to one vote for each share held and fractional votes for fractional shares held. As of the Record Date, the number of shares issued and outstanding of the Fund is listed on Appendix B. As of October 4, 2007 no person owned beneficially more than 5% of any class of the Fund, except as set forth in Appendix B. To the best of the Fund’s knowledge, as of October 4, 2007, no Trustee or officer owned beneficially more than 1% of any class of the Fund.

Thirty-three and one-third percent (33 1/3%) of the Fund’s shares, represented in person or by proxy, will constitute a quorum for the Special Meeting and must be present for the transaction of business at the Special Meeting. Only Proxies that are voted, abstentions and “broker non-votes” will be counted toward establishing a quorum. “Broker non-votes” are shares held by a broker or nominee as to which

instructions have not been received from the beneficial owners or persons entitled to vote, and the broker or nominee does not have discretionary voting power.

In the event that a quorum is not present at the Special Meeting for the Fund, or a quorum is present but sufficient votes to approve Proposal I are not received, the persons named as proxies may propose one or more adjournments of the Special Meeting for the Fund to permit further solicitation of Proxies. Any such adjournment will require the affirmative vote of a majority of the Fund’s shares represented at the Special Meeting in person or by proxy (excluding abstentions and broker non-votes). The person named as proxies will vote those Proxies that they are entitled to vote “FOR” Proposal I in favor of an adjournment of the Special Meeting, and will vote those Proxies required to be voted AGAINST the proposal for the Fund against such adjournment. A shareholder vote may be taken on any proposal prior to any such adjournment if sufficient votes have been received and it is otherwise appropriate.

The individuals named as proxies on the enclosed Proxy will vote in accordance with your directions, if your Proxy is received properly executed. If we receive your Proxy, and it is executed properly, but you give no voting instructions with respect to a proposal, your shares will be voted “FOR” Proposal I. The duly appointed proxies may, in their discretion, vote upon such other matters as may properly come before the Special Meeting.

In order that your shares may be represented at the Special Meeting, you are requested to vote your shares by mail, the Internet, or by telephone by following the enclosed instructions. IF YOU VOTE BY TELEPHONE OR INTERNET, PLEASE DO NOT RETURN YOUR PROXY CARD, UNLESS YOU LATER ELECT TO CHANGE YOUR VOTE. You may revoke your Proxy: (a) at any time prior to its exercise by written notice of its revocation to the secretary of TA IDEX prior to the Special Meeting; (b) by the subsequent execution and return of another Proxy prior to the Special Meeting; or (c) by being present and voting in person at the Special Meeting and giving oral notice of revocation to the chairman of the Special Meeting. However, attendance in-person at the Special Meeting, by itself, will not revoke a previously-tendered Proxy.

Required Vote. Approval of Proposal I requires the affirmative vote of at least a majority of the Fund’s shares entitled to vote at the meeting. Abstentions and broker non-votes will have the same effect as a vote against Proposal I.

Shareholder Proposals. As a general matter, TA IDEX does not hold annual meetings of shareholders. Shareholders wishing to submit proposals for inclusion in a proxy statement for a subsequent meeting should send their written proposal to the Secretary of TA IDEX, 570 Carillon Parkway, St. Petersburg, Florida 33716. Proposals should be in writing, should be signed by the shareholder and should identify the full name of the Fund.

Proposals must be received by a reasonable time prior to the date of a meeting of shareholders to be considered for inclusion in the proxy materials for a meeting. Timely submission of a proposal does not, however, necessarily mean that the proposal will be included. Persons named as proxies for any subsequent shareholders’ meeting will vote in their discretion with respect to proposals submitted on an untimely basis.

Shareholders Sharing the Same Address. As permitted by law, only one copy of this Proxy Statement is being delivered to shareholders residing at the same address, unless such shareholders have notified TA IDEX of their desire to receive multiple copies of the shareholder reports and proxy statements TA IDEX sends. If you would like to receive an additional copy, please contact TA IDEX by writing to TA IDEX’s address or by calling the telephone number shown on the front page of this Proxy Statement. TA IDEX will then promptly deliver, upon request, a separate copy of the Proxy Statement to any shareholder residing at an address to which only one copy was mailed. Shareholders wishing to receive separate copies of TA IDEX’s shareholder reports and proxy statements in the future, and shareholders sharing an address that wish to receive a single copy if they are receiving multiple copies, should also direct requests as indicated.

TO ENSURE THE PRESENCE OF A QUORUM AT THE SPECIAL MEETING, PROMPT EXECUTION AND RETURN OF THE ENCLOSED PROXY IS REQUESTED. A SELF-ADDRESSED, POSTAGE-PAID ENVELOPE IS ENCLOSED FOR YOUR CONVENIENCE.

APPENDIX A

TRANSAMERICA IDEX MUTUAL FUNDS

TA IDEX Protected Principal Stock

FORM OF
PLAN OF LIQUIDATION AND DISSOLUTION

This Plan of Liquidation and Dissolution (the “Plan”) is adopted by Transamerica IDEX Mutual Funds (the “Trust”), a Delaware statutory trust, with respect to TA IDEX Protected Principal Stock (“Fund”), a series of the Trust. The Trust is an open-end management investment company registered under the Investment Company Act of 1940 (the “Investment Company Act”), and this Plan is adopted as a plan of liquidation for purposes of the Internal Revenue Code of 1986, as amended (the “IRC”), and the regulations thereunder, with respect to the Fund. The Plan is intended to accomplish the complete liquidation and dissolution of the Fund and the redemption of the Fund’s outstanding shares in conformity with all applicable laws, including the laws of the State of Delaware, the Investment Company Act, the IRC, and the Trust’s charter documents.

WHEREAS, the Trust’s Board of Trustees (the “Board”), on behalf of the Fund, has determined that it is in the best interests of the Fund and the beneficial owners of the Fund’s shares to liquidate and dissolve the Fund; and

WHEREAS, the Board has considered and unanimously adopted this Plan as the method of liquidating the Fund and has recommended that shareholders of the Fund approve the Plan at a special meeting of the Fund’s shareholders called for such purpose;

NOW THEREFORE, the liquidation and dissolution of the Fund shall be carried out in the manner hereinafter set forth:

1. Effective Date of Plan. The Plan shall become effective immediately with respect to the Fund upon a vote approving the Plan by the affirmative vote of at least a majority of the outstanding securities of the Fund entitled to vote at a special meeting of shareholders of the Fund duly called for such purpose to be held on November 27, 2007 or such other date as determined by the Board, which date is hereinafter called the “Effective Date.”

2. Dissolution. As promptly as practicable, consistent with the Provisions of the Plan, the Fund shall be dissolved in accordance with the laws of the State of Delaware and the Trust’s charter documents.

3. Cessation of Business. As soon as is reasonable and practicable on or after the Effective Date, the Fund shall cease its business as an investment company and shall not engage in any business activities except for the purposes of winding up its business and affairs, marshalling and preserving the value of its assets, and distributing its assets to shareholders in redemption of their shares in accordance with the provisions of the Plan after the payment to (or reservation of assets for payment to) all creditors of the Fund and discharging or making reasonable provisions for the Fund’s liabilities.

4. Liquidation of Assets. As soon as is reasonable and practicable before, on, or after the Effective Date, all portfolio securities of the Fund shall be converted to cash or cash equivalents. In the alternative, if determined to be in the best interests of a Fund and the beneficial owners of its shares, the Fund may elect not to liquidate its portfolio assets and shall rather distribute such amounts in-kind to its shareholders consistent with applicable statutes, regulations, and interpretations, which shall constitute a liquidating distribution for this purpose.

5. Payment of Debts. As soon as is reasonable and practicable on or after the Effective Date, subject to the provisions of Section 6 hereof, the Fund shall determine and pay, or set aside in cash or equivalents, the amount of all known or reasonably ascertainable liabilities of the Fund incurred or expected to be incurred prior to the date of the liquidating distribution provided for in Section 6 below, subject to Section 8 below.

6. Liquidating Distribution. As soon as possible on or after the Effective Date, or such other date as determined by the Board (the “Liquidation Date”), the Fund shall mail the following to a shareholder of record on the business day preceding the Liquidation Date in redemption of such shareholder’s shares of the Fund: (1) a liquidating distribution (or distributions, if more than one distribution shall be necessary), which may be in cash or cash equivalents or in-kind, equal to the shareholder’s proportionate interest in the net assets of the Fund (after giving effect to amounts considered necessary to satisfy the Fund’s liabilities); and (2) information concerning the sources of the liquidating distribution. Upon the mailing of the liquidating distribution, all outstanding shares of the Fund will be deemed cancelled.

If the Trust is unable to make distributions to all of the Fund’s shareholders because of the inability to locate shareholders to whom distributions in cancellation and redemption of the Fund’s shares are payable, the Board may create, in the name and on behalf of the Fund, a trust with a financial institution and, subject to applicable abandoned property laws, deposit any remaining assets of the Fund in such trust for the benefit of the shareholders that cannot be located. The expenses of such trust shall be charged against the assets therein.

7. Satisfaction of Federal Income and Excise Tax Distribution Requirements. If necessary, the Fund shall, by the Liquidation Date, have declared and paid a dividend or dividends which, together with all previous such dividends, shall have the effect of distributing to the Fund’s shareholders all of the Fund’s investment company taxable income for the taxable years ending at or prior to the Liquidation Date (computed without regard to any deduction for dividends paid), and all of the Fund’s net capital gain, if any, realized in the taxable years ending at or prior to the Liquidation Date (after reduction for any available capital loss carry-forward) and any additional amounts necessary to avoid any excise tax for such periods.
