You are cordially invited to attend a special joint shareholders meeting (the "Special Meeting") of each of Credit Suisse Large Cap Value Fund (the "Large Cap Value Fund"), a series of Credit Suisse Capital Funds, Credit Suisse Large Cap Growth Fund (the "Large Cap Growth Fund"), and Credit Suisse Mid-Cap Core Fund, Inc. (the "Mid-Cap Core Fund" and collectively with the Large Cap Value Fund and the Large Cap Growth Fund, the "Funds" and each, a "Fund") to be held on Friday, August 27, 2010. Before the Special Meeting, I would like to provide you with additional background information and ask for your vote on an important proposal affecting your Fund.

We are asking for your vote to approve a proposed reorganization of your Fund with Credit Suisse Large Cap Blend Fund, Inc., (the "Large Cap Blend Fund"). In this reorganization, your Fund shares would, in effect, be exchanged for the same class of shares of the Large Cap Blend Fund (with the exception of Advisor Class shares of each Fund, which will be exchanged for Class A shares of the Large Cap Blend Fund) with the same aggregate net asset value of the Fund shares that you currently hold. It is currently anticipated that the reorganization of each Fund should be effected on a tax-free basis for federal income tax purposes. There may be taxable distributions to shareholders made prior to the reorganization.

The reorganization of each Fund is being proposed because Credit Suisse Asset Management, LLC ("Credit Suisse"), each Fund's and the Large Cap Blend Fund's investment adviser, believes that shareholders of each fund will benefit more from the potential operating efficiencies and economies of scale that may be achieved by combining the funds' assets in the respective reorganizations, than by continuing to operate, in each case, the two funds separately. Credit Suisse further believes that it is in the best interests of each Fund's shareholders to combine the Fund's assets with a fund that has the same or a lower gross expense structure and the same or a lower net expense structure (i.e., after voluntary fee waivers and expense reimbursements), although the performance history of each Fund is generally better than that of the Large Cap Blend Fund. Credit Suisse believes that the Large Cap Blend Fund's investment objective and strategies make it a compatible fund within the Credit Suisse complex for a reorganization with each of the Funds. The portfolio managers of each of the Large Cap Value Fund, the Large Cap Growth Fund, the Mid-Cap Core Fund and the Large Cap Blend Fund use the same proprietary quantitative models in selecting securities in accordance with the Funds' respective strategies.

The Board of Trustees of Credit Suisse Capital Funds, on behalf of the Large Cap Value Fund, the Board of Trustees of the Large Cap Growth Fund and the Board of Directors of the Mid-Cap Core Fund, as applicable, has determined that the proposed reorganization of the relevant Fund with the Large Cap Blend Fund is in the best interests of the relevant Fund, and the interests of the relevant Fund's existing shareholders will not be diluted as a result of the applicable reorganization. If a reorganization is approved by shareholders, it is expected that the proposed reorganization will take effect on or about September 17, 2010. Included in this booklet is information about the upcoming Special Meeting:

• A Notice of a Special Meeting of Shareholders, which summarizes the matter(s) on which you are being asked to vote; and

• The Combined Prospectus/Proxy Statement, which provides detailed information on the Large Cap Blend Fund, the specific proposal relating to your Fund being considered at the Special Meeting, and why the proposal is being made.

I encourage you to review the enclosed materials carefully. As a shareholder, your vote is important, and we hope that you will respond today to ensure that your shares will be represented at the Special Meeting. You may vote in one of the following ways:

• By calling us toll-free at the telephone number listed on the enclosed proxy card;

To avoid the wasteful and unnecessary expense of further solicitation, we urge you to promptly indicate your vote on the enclosed proxy card, date and sign it and return it in the envelope provided, or record your voting instructions by telephone or via the internet, no matter how large or small your holdings may be. If you submit a properly executed proxy but do not indicate how you wish your shares to be voted, your shares will be voted "For" the applicable reorganization. If your shares are held through a broker, you must provide voting instructions to your broker about how to vote your shares in order for your broker to vote your shares at the Special Meeting.

We recommend that you read the complete Combined Prospectus/Proxy Statement. For your convenience, we have provided a brief overview of the issue(s) to be voted on.

(i) an agreement and plan of reorganization (a "Reorganization Agreement") between Credit Suisse Capital Funds (the "Capital Funds Trust"), on behalf its series, Credit Suisse Large Cap Value Fund (the "Large Cap Value Fund"), and Credit Suisse Large Cap Blend Fund, Inc. (the "Large Cap Blend Fund");

(ii) a Reorganization Agreement between Credit Suisse Large Cap Growth Fund (the "Large Cap Growth Fund") and the Large Cap Blend Fund;

(iii) a Reorganization Agreement between Credit Suisse Mid-Cap Core Fund, Inc. (the "Mid-Cap Core Fund" and collectively with the Large Cap Value Fund and the Large Cap Growth Fund, the "Target Funds" and each, a "Target Fund"), and the Large Cap Blend Fund (the Large Cap Blend Fund, together with the Target Funds, the "Funds" and each, a "Fund").

The Large Cap Blend Fund pursues an investment objective identical or substantially similar to that of each of the Target Funds and pursues certain investment strategies similar to that of each of the Target Funds. If the proposed reorganization ("Reorganization") relating to your Target Fund is approved and completed, an account at the Large Cap Blend Fund will be set up in your name, you will become a shareholder of the Large Cap Blend Fund, and your Target Fund will be terminated as a trust or corporation, or series thereof, as applicable. Please refer to the Combined Prospectus/Proxy Statement for a detailed explanation of the proposed Reorganization relating to your Target Fund and for a more complete description of the Large Cap Blend Fund.

A: After careful consideration, each of the Board of Trustees of the Capital Funds Trust, on behalf of the Large Cap Value Fund, the Board of Trustees of the Large Cap Growth Fund and the Board of Directors of the Mid-Cap Core Fund (collectively, the "Boards" and each, a "Board") has determined that each proposed Reorganization is in the best interests of the relevant Target Fund and the interests of the Target Fund's existing shareholders will not be diluted as a result of the Reorganization and, therefore, recommends that you cast your vote "For" the proposed Reorganization. The relevant Board has determined that shareholders of a Target Fund may benefit from (i) the possible operating efficiencies from the larger net asset size of the combined fund, (ii) the expectation that the combined fund will have operating expenses the same as or below those of the Target Fund and (iii) the similarity of the investment objective and the compatibility of certain investment strategies of the Large Cap Blend Fund.

A: If shareholders of a Target Fund approve the proposed Reorganization relating to their Fund, all the assets and liabilities of the Target Fund will be combined with those of the Large Cap Blend Fund, an account will be set up in your name at the Large Cap Blend Fund and you will receive shares of the Large Cap Blend Fund. Unless you are an Advisor Class shareholder of a Target Fund, you will receive the same class of shares of the Large Cap Blend Fund as you currently hold of your Target Fund; Advisor Class shareholders of each Target Fund will receive Class A shares of the Large Cap Blend Fund (but will not be charged Class A's sales load on shares received in the Reorganization). The aggregate net asset value of the shares you receive in the Reorganization relating to your Target Fund will equal the aggregate net asset value of the shares you own immediately prior to the Reorganization. As a result of a Reorganization, however, a shareholder of a Target Fund will hold a smaller percentage of ownership in the combined fund than he or she held in the Target Fund prior to the Reorganization.

Q: IN THE REORGANIZATION, WILL I RECEIVE SHARES OF THE LARGE CAP BLEND FUND OF THE SAME CLASS AS THE SHARES OF THE TARGET FUND THAT I NOW HOLD?

A: Unless you are an Advisor Class shareholder of a Target Fund, you will receive shares of the Large Cap Blend Fund of the same class as the shares you own of your Target Fund; Advisor Class shareholders of each Target Fund will receive Class A shares of the Large Cap Blend Fund (but will not be charged Class A's sales load on shares received in the Reorganization).

Q: WILL I OWN THE SAME NUMBER OF SHARES OF THE LARGE CAP BLEND FUND AS I CURRENTLY OWN OF MY TARGET FUND?

A: No. You will receive shares of the Large Cap Blend Fund with the same aggregate net asset value as the shares of the Target Fund you own prior to the Reorganization relating to your Fund. However, the number of shares you receive will depend on the relative net asset value of the shares of the relevant Target Fund and the Large Cap Blend Fund on the closing date. Thus, on the closing date, if the net asset value of a share of the Large Cap Blend Fund is lower than the net asset value of the corresponding share class of the relevant Target Fund, you will receive a greater number of shares of the Large Cap Blend Fund in the applicable Reorganization than you held in the Target Fund before the Reorganization. On the other hand, if the net asset value of a share of the Large Cap Blend Fund is higher than the net asset value of the corresponding share class of the relevant Target Fund, you will receive fewer shares of the Large Cap Blend Fund in the applicable Reorganization than you held in the Target Fund before the Reorganization. The aggregate net asset value of your Large Cap Blend Fund shares immediately after the applicable Reorganization will be the same as the aggregate net asset value of your Target Fund shares immediately prior to the Reorganization.

A: Your rights as a shareholder will not change in any substantial way as a result of the Reorganization relating to your Target Fund. However, if you are a shareholder of the Large Cap Growth Fund, a Massachusetts business trust, or the Large Cap Value Fund, a series of the Capital Funds Trust, a Massachusetts business trust, you will be a shareholder of the Large Cap Blend Fund, which is a Maryland corporation, as a result of the applicable Reorganization. If you are a shareholder of the Mid-Cap Core Fund, a Maryland corporation, you will continue to be a shareholder of a Maryland corporation as a result of the applicable Reorganization. As discussed in the Combined Proxy Statement/Prospectus, there are certain differences between Maryland corporations and Massachusetts business trusts with respect to shareholder rights. The shareholder services available to you after the applicable Reorganization will be identical, except in the case of Advisor Class shareholders of each Target Fund who will receive Class A shares of the Large Cap Blend Fund in the applicable Reorganization.

• the Advisor Class does not impose minimums for initial or subsequent investments, while Class A generally requires initial and subsequent investments to be greater than $2,500 and $100, respectively;

• the Advisor Class assesses an ongoing distribution and service fee of 0.50% per annum without an initial sales charge and Class A assesses an ongoing distribution and service fee of 0.25% per annum with an initial sales charge of up to 5.75% (which, as noted, will be waived with respect to Class A shares received in the Reorganizations);

• Advisor Class shareholders receive shareholder services directly through their Institutional Services Center, including account opening, obtaining fund information and buying, selling or exchanging shares, while Class A shareholders receive such services through a third party financial intermediary; and

• the Advisor Class is not subject to any minimums in connection with automatic investments or withdrawals, but Class A is subject to a $50 minimum for automatic investments and a $250 minimum for automatic withdrawals.

Q: WHO WILL ADVISE THE LARGE CAP BLEND FUND ONCE THE REORGANIZATIONS ARE COMPLETED?

A: As you know, each Target Fund is advised by Credit Suisse Asset Management, LLC ("Credit Suisse"). The Large Cap Blend Fund also is advised by Credit Suisse and will continue to be advised by Credit Suisse once the Reorganizations are completed.

Q: WILL I HAVE TO PAY ANY SALES LOAD, COMMISSION OR OTHER SIMILAR FEE IN CONNECTION WITH THE REORGANIZATION?

A: No, you will not pay any sales load, commission or other similar fee in connection with the Reorganization relating to your Target Fund. As more fully discussed in the Combined Prospectus/Proxy Statement, the holding period with respect to any contingent deferred sales charge that applies to shares of the Large Cap Blend Fund acquired by you in the Reorganization relating to your Target Fund will be measured from the earlier of the time (i) you purchased your Target Fund shares or (ii) you purchased your shares of any other fund advised by Credit Suisse and subsequently exchanged them for shares of the Target Fund.

Advisor Class shareholders of each Target Fund will receive Class A shares of the Large Cap Blend Fund in the applicable Reorganization. While Class A's sales load will be waived with respect to those Class A shares received in the applicable Reorganization, to the extent such shareholders purchase additional Class A shares following the close of the applicable Reorganization, such additional shares will be subject to Class A's sales load.

Q: HOW DO OPERATING EXPENSES PAID BY THE LARGE CAP BLEND FUND COMPARE TO THOSE PAYABLE BY EACH TARGET FUND?

A: Following the Reorganizations, the Large Cap Blend Fund's gross operating expenses are expected to be the same as or below those of each Target Fund and the Large Cap Blend Fund's net projected operating expenses (i.e., after voluntary fee waivers and expense reimbursements) are expected to be the same as or below those of each Target Fund.

Q: WHAT WILL I HAVE TO DO TO OPEN AN ACCOUNT IN THE LARGE CAP BLEND FUND? WHAT HAPPENS TO MY ACCOUNT IF THE REORGANIZATION IS APPROVED?

A: If the Reorganization relating to your Target Fund is approved, an account will be set up in your name and your shares automatically will be converted into shares of the Large Cap Blend Fund. We will send you written confirmation that this change has taken place. Unless you are an Advisor Class shareholder of a Target Fund, you will receive the same class of shares of the Large Cap Blend Fund as you currently hold of your Target Fund; Advisor Class shareholders of each Target Fund will receive Class A shares of the Large Cap Blend Fund (but will not be charged Class A's sales load on shares received in the Reorganization). The aggregate net asset value of the shares you receive in the Reorganization relating to your Target Fund will be equal to the aggregate net asset value of the shares you own immediately prior to the Reorganization. No certificates for shares will be issued in connection with a Reorganization. If you currently hold certificates representing your Target Fund shares, it is not necessary to surrender such certificates.

A: If a Reorganization is not approved by shareholders of the relevant Target Fund, you will continue to be a shareholder of the Target Fund and the relevant Board

will consider other possible courses of action available to it, including resubmitting the Reorganization proposal to shareholders.

Q: WHAT HAPPENS IF SHAREHOLDERS OF ONE TARGET FUND APPROVE THEIR REORGANIZATION, WHILE SHAREHOLDERS OF THE OTHER TARGET FUND(S) DO NOT?

A: Each Reorganization is a separate transaction and is not dependent on the approval of the other Reorganizations. Thus, if shareholders of one Target Fund approve the Reorganization relating to their Fund, their Fund will be reorganized, even if shareholders of one or both of the other Target Funds do not approve the Reorganization relating to their Funds.

A: Each Reorganization is currently expected to qualify as a tax-free "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. If a Reorganization so qualifies, in general, the relevant Target Fund will not recognize any gain or loss as a result of the transfer of all of its assets and liabilities in exchange solely for shares of the Large Cap Blend Fund and the assumption of the Target Fund's liabilities by the Large Cap Blend Fund, or as a result of the Target Fund's liquidation, and you will not recognize any gain or loss upon your receipt solely of shares of the Large Cap Blend Fund in connection with the Reorganization.

To the extent that prior to the applicable Reorganization, the portfolio holdings of a Target Fund are sold by the Target Fund in connection with the Reorganization, the tax impact of such sales will depend on the difference between the price at which such portfolio holdings are sold and the Target Fund's basis in such holdings. Any capital gains recognized in these sales on a net basis will be distributed, if required, to such Target Fund's shareholders as either capital gain dividends (to the extent of net realized long-term capital gains) or ordinary dividends (to the extent of net realized short-term capital gains) during or with respect to the year of sale, and such distributions will be taxable to shareholders.

A: Credit Suisse or its affiliates will pay all reasonable, ordinary expenses incurred in connection with each Reorganization.

Q: WHAT IF I REDEEM OR EXCHANGE MY SHARES BEFORE THE REORGANIZATION TAKES PLACE?

A: If you choose to redeem or exchange your shares before the Reorganization relating to your Target Fund takes place, the redemption or exchange will be treated as a normal redemption or exchange of shares and, generally, will be a taxable transaction and any applicable redemption fees will be applied. Also, in the case of redemptions, you will be responsible for payment of any applicable contingent deferred sales charges.

A: You may cast your vote by mail, telephone or internet or in person at the special joint shareholders meeting. To vote by mail, please mark your vote on the enclosed proxy card and sign, date and return the card in the postage-paid envelope provided. To vote by telephone or over the internet, please have the proxy card in hand and call the telephone number or go to the website address listed on the enclosed form and follow the instructions.

A: If you are a shareholder of more than one Target Fund, you will receive a proxy card for each Fund.

A: If approved by shareholders, each Reorganization is expected to occur on or about September 17, 2010. A Reorganization will not take place if the Reorganization is not approved by the relevant Target Fund's shareholders.

A: Your vote makes a difference. If many small shareholders just like you fail to vote their proxies, your Target Fund may not receive enough votes to go forward with the special joint shareholders meeting and additional costs will be incurred through further proxy solicitations.

A: You may call The Altman Group, Inc., our proxy solicitation firm at (866) 745-0271.

Important additional information about the proposal is set forth in the accompanying Combined Prospectus/Proxy Statement. Please read it carefully.

To the Shareholders of each of Credit Suisse Large Cap Value Fund, Credit Suisse Large Cap Growth Fund and Credit Suisse Mid-Cap Core Fund:

This is to notify you that a Joint Special Meeting of Shareholders (the "Special Meeting") of each of Credit Suisse Large Cap Value Fund (the "Large Cap Value Fund"), a series of Credit Suisse Capital Funds, a Massachusetts business trust (the "Capital Funds Trust"), Credit Suisse Large Cap Growth Fund, a Massachusetts business trust (the "Large Cap Growth Fund"), and Credit Suisse Mid-Cap Core Fund, Inc., a Maryland corporation (the "Mid-Cap Core Fund" and collectively with the Large Cap Value Fund and the Large Cap Growth Fund, the "Target Funds" and each, a "Target Fund"), will be held on Friday, August 27, 2010 at 1:00 p.m., Eastern time, at the offices of Credit Suisse Asset Management, LLC ("Credit Suisse"), located at Eleven Madison Avenue, New York, New York 10010 for the following purposes:

1. The shareholders of each Target Fund are being asked to consider a proposal to approve an Agreement and Plan of Reorganization ("Reorganization Agreement") relating to their Target Fund pursuant to which (i) the Target Fund would transfer to Credit Suisse Large Cap Blend Fund, Inc., a Maryland corporation (the "Large Cap Blend Fund"), all of its assets in exchange for Class A, Class B, Class C and Common Class shares of the Large Cap Blend Fund and the assumption by the Large Cap Blend Fund of the Target Fund's liabilities, (ii) such shares of the Large Cap Blend Fund would be distributed to shares of the Target Fund in liquidation of the Target Fund, and (iii) the Target Fund would subsequently be terminated as a trust or corporation, or series thereof, as applicable; and

2. To transact such other business as may properly be presented at the Special Meeting or any adjournment or postponement thereof.

The Board of Trustees of the Capital Funds Trust, the Board of Trustees of the Large Cap Growth Fund and the Board of Directors of the Mid-Cap Core Fund (collectively, the "Boards" and each, a "Board") have fixed the close of business on June 11, 2010 as the record date for determination of shareholders of each Target Fund entitled to notice of, and to vote at, the Special Meeting and any adjournments or postponements thereof.

THE RELEVANT BOARD UNANIMOUSLY RECOMMENDS THAT
YOU VOTE "FOR" THE PROPOSAL RELATING TO YOUR TARGET FUND.

It is very important that your vote be received prior to the Special Meeting date. Voting instructions for shares held of record in the name of a nominee, such as a broker-dealer or director of an employee benefit plan, may be subject to earlier cut-off dates established by such intermediaries for receipt of such instructions.

Your vote is important regardless of the size of your holdings in the Target Fund. Whether or not you expect to be present at the Special Meeting, please complete and sign the enclosed proxy card and return it promptly in the enclosed envelope. Certain shareholders may also vote by telephone or over the Internet; please see page the enclosed Proxy Card for details on how to do so. If you vote by proxy and then desire to change your vote or vote in person at the Special Meeting, you may revoke your proxy at any time prior to the votes being tallied at the Special Meeting. Please refer to the section of the enclosed Combined Prospectus/Proxy Statement entitled "Voting Information and Requirements-Manner of Voting" for more information.

This Combined Prospectus/Proxy Statement is furnished to you as a shareholder of Credit Suisse Large Cap Value Fund (the "Large Cap Value Fund"), a series of Credit Suisse Capital Funds, a Massachusetts business trust (the "Capital Funds Trust"), Credit Suisse Large Cap Growth Fund, a Massachusetts business trust (the "Large Cap Growth Fund"), or Credit Suisse Mid-Cap Core Fund, Inc., a Maryland corporation (the "Mid-Cap Core Fund" and collectively with the Large Cap Value Fund and the Large Cap Growth Fund, the "Target Funds" and each, a "Target Fund"). A joint special meeting of shareholders of each of the Target Funds (the "Special Meeting") will be held at the offices of Credit Suisse Asset Management, LLC ("Credit Suisse"), located at Eleven Madison Avenue, New York, New York 10010, on Friday, August 27, 2010 at 1:00 p.m., Eastern time, to consider the items that are listed below and discussed in greater detail elsewhere in this Combined Prospectus/Proxy Statement. Shareholders of record of each Target Fund at the close of business on June 11, 2010 (the "Record Date") are entitled to notice of, and to vote at, the Special Meeting or any adjournments or postponements thereof. This Combined Prospectus/Proxy Statement, proxy card and accompanying Notice of Special Meeting of Shareholders were first sent or given to shareholders of each Target Fund on or about July 15, 2010. Whether or not you expect to attend the Special Meeting or any adjournment or postponement thereof, each of the Board of Trustees of the Capital Funds Trust, on behalf of the Large Cap Value Fund, the Board of Trustees of the Large Cap Growth Fund and the Board of Directors of the Mid-Cap Core Fund (collectively, the "Boards" and each, a "Board"), as applicable, requests that shareholders vote their shares by completing and returning the enclosed proxy card.

2. To transact such other business as may properly be presented at the Special Meeting or any adjournment or postponement thereof.

The Board of Trustees of the Capital Funds Trust has approved a reorganization ("Reorganization") with respect to the Large Cap Value Fund, by which the Large Cap Value Fund, a series of the Capital Funds Trust, an open-end management investment company, would be acquired by the Large Cap Blend Fund, an open-end management investment company. The Board of Trustees of the Large Cap Growth Fund has approved a Reorganization by which the Large Cap Growth Fund, an open-end management investment company, would be acquired by the Large Cap Blend Fund. The Board of Directors of the Mid-Cap Core Fund has approved a Reorganization by which the Mid-Cap Core Fund, an open-end management investment company, would be acquired by the Large Cap Blend Fund. The Large Cap Blend Fund has an investment objective of long-term appreciation of capital, which is identical to that of the Large Cap Growth Fund, whose investment objective is long-term capital appreciation, and substantially similar to those of each of the Large Cap Value Fund and the Mid-Cap Core Fund whose investment objectives are long-term capital appreciation and continuity of income and maximum capital appreciation, respectively. The Large Cap Blend Fund also has certain investment strategies that are compatible with those of each of the Target Funds. Each Target Fund and the Large Cap Blend Fund, however, employ certain differing investment strategies to achieve their respective objectives, as discussed in more detail below. For more information on each Fund's investment strategies see "Summary — Investment Objectives and Principal Investment Strategies" below.

If a Target Fund's shareholders approve the Reorganization relating to their Fund, the Target Fund will transfer its assets to the Large Cap Blend Fund. The Large Cap Blend Fund will assume the liabilities of the Target Fund and will issue shares to the Target Fund in an amount equal to the aggregate net asset value of the outstanding shares of the Target Fund. Immediately thereafter, the Target Fund will distribute these shares of the Large Cap Blend Fund to its shareholders. After distributing these shares, the Target Fund will be terminated as a trust or a corporation, or series thereof, as applicable. When the Reorganization is complete, the Target Fund's shareholders will hold the same class of shares of the Large Cap Blend Fund as they currently hold of the Target Fund, with the exception of Advisor Class shareholders of each Target Fund who will hold Class A shares of the Large Cap Blend Fund. The aggregate net asset value of the Large Cap Blend Fund shares received in the Reorganization will equal the aggregate net asset value of the Target Fund shares held by Target Fund shareholders immediately prior to the Reorganization. As a result of the Reorganization, however, a shareholder of the Target Fund will hold a smaller percentage of ownership in the combined fund than such shareholder held in the Target Fund prior to the Reorganization.

This Combined Prospectus/Proxy Statement sets forth concisely the information shareholders of each Target Fund should know before voting on the Reorganization relating to their Fund and constitutes an offering of Class A, Class B, Class C and Common Class shares of the Large Cap Blend Fund only. Please read it carefully and retain it for future reference.

The Boards know of no business other than that discussed above that will be presented for consideration at the Special Meeting. If any other matter is properly presented, it is the intention of the persons named in the enclosed proxy to vote in accordance with their best judgment.

No person has been authorized to give any information or make any representation not contained in this Combined Prospectus/Proxy Statement and, if so given or made, such information or representation must not be relied upon as having been authorized. This Combined Prospectus/Proxy Statement does not constitute an offer to sell or a solicitation of an offer to buy any securities in any jurisdiction in which, or to any person to whom, it is unlawful to make such offer or solicitation.

Neither the SEC nor any state regulator has approved or disapproved of these securities or passed upon the adequacy of this Combined Prospectus/Proxy Statement. Any representation to the contrary is a criminal offense.

The following is a summary of certain information contained elsewhere in this Combined Prospectus/Proxy Statement and is qualified in its entirety by reference to the more complete information contained herein. Shareholders should read the entire Combined Prospectus/Proxy Statement carefully.

Each of the Capital Funds Trust, the Large Cap Growth Fund, the Mid-Cap Core Fund and the Large Cap Blend Fund is an open-end management investment company registered with the SEC. The Large Cap Value Fund is a series of the Capital Funds Trust. Each of the Capital Funds Trust and the Large Cap Growth Fund is organized as a business trust under the laws of the Commonwealth of Massachusetts and each of the Mid-Cap Core Fund and the Large Cap Blend Fund is organized as a corporation under the laws of the State of Maryland. The investment objective of the Large Cap Value Fund is to provide long-term capital appreciation and continuity of income. The investment objective of the Large Cap Growth Fund is to provide long-term capital appreciation. The investment objective of the Mid-Cap Core Fund is to provide maximum capital appreciation. The investment objective of the Large Cap Blend Fund is to provide long-term appreciation of capital.

Each of the Large Cap Value Fund and the Large Cap Blend Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of U.S. companies with large market capitalizations ("large companies"). A principal difference between such Funds is that the Large Cap Value Fund invests principally in "value" stocks, while the Large Cap Blend Fund invests principally in a blend of "value" and "growth" stocks. Accordingly, the Large Cap Value Fund considers a large company to be one that is represented in the Russell 1000^® Value Index (the "Russell Value Index") or has similar attributes and capitalization to companies in the Russell Value Index and the Large Cap Blend Fund considers a large company to be one that is represented in the S&P 500 Index or has similar attributes and capitalization to companies in the S&P 500 Index.

The Large Cap Growth Fund invests substantially all of its assets — but no less than 80% of its assets — in equity securities of large cap U.S. companies. As noted above, the Large Cap Blend Fund invests at least 80% of its assets, plus any borrowings for investment purposes, in equity securities of U.S. companies with large market capitalizations. A principal difference between such Funds is that the Large Cap Growth Fund invests principally in "growth" stocks, while the Large Cap Blend Fund invests principally in a blend of "growth" and "value" stocks. Accordingly, the Large Cap Growth Fund considers a large company to be one that is represented in the Russell 1000^® Growth Index (the "Russell Growth Index") or has similar attributes and capitalization to companies in the Russell Growth Index and, as noted above, the Large Cap Blend Fund considers a large company to be one that is represented in the S&P 500 Index or has similar attributes and capitalization to companies in the S&P 500 Index.

Each of the Mid-Cap Core Fund and the Large Cap Blend Fund invests in a blend of "growth" and "value" stocks. A principal difference between such Funds is that the Mid-Cap Core Fund invests principally in "mid-cap" stocks, while the Large Cap Blend Fund invests principally in "large cap" stocks. The Mid-Cap Core Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of "mid cap" companies. The Mid-Cap Core Fund considers a "mid cap" company to be one that is represented in the Standard & Poor's MidCap 400^® Index (the "S&P 400 Index") or has similar attributes and capitalizations to companies in the S&P 400 Index. As noted above, the Large Cap Blend Fund invests at least 80% of its assets, plus any borrowings for investment purposes, in equity securities of U.S. companies with large market capitalizations. The Large Cap Blend Fund considers a large company to be one that is represented in the S&P 500 Index or has similar attributes and capitalization to companies in the S&P 500 Index. As of December 31, 2009, the market capitalizations of companies included in the S&P 400 Index were $293.49 million to $8.24 billion and the market capitalizations of companies included in the S&P 500 Index were $1.12 billion to $322.67 billion.

Credit Suisse Asset Management, LLC ("Credit Suisse") serves as the investment adviser of each of the Funds. Each Fund publicly offers its shares on a continuous basis, and shares may be purchased through the Fund and/or numerous financial intermediaries. Shareholders of each Fund have the right to exchange their shares for shares of the same class of other Credit Suisse funds at net asset value per share at the time of exchange, subject to certain limitations. Each Fund permits its shareholders to redeem their shares at any time upon proper notice (subject, in certain cases, to redemption fees and/or contingent deferred sales charges).

The governing Board of each Fund, including the members of the Board who are not "interested persons" of the relevant Fund (as defined in the 1940 Act) (the "Independent Trustees/Directors"), has unanimously approved the applicable Reorganization. Subject to approval by the relevant Target Fund shareholders, each Reorganization provides for:

• the transfer of all the assets of the relevant Target Fund to the Large Cap Blend Fund in exchange for the assumption of the Target Fund's liabilities by the Large Cap Blend Fund and Class A, Class B, Class C and Common Class shares of the Large Cap Blend Fund;

• the distribution of such Class A, Class B, Class C and Common Class shares of the Large Cap Blend Fund to the relevant Target Fund's shareholders; and

• the termination of the relevant Target Fund as a trust or corporation, or series thereof, as applicable.

If a proposed Reorganization is approved and completed, the Target Fund's shareholders would hold shares of the same class of the Large Cap Blend Fund as they currently hold of the Target Fund (with the exception of Advisor Class shareholders of each Target Fund who would hold Class A shares of the

Large Cap Blend Fund). The aggregate net asset value of the shares you receive in the Reorganization relating to your Target Fund will equal the aggregate net asset value of the shares you own immediately prior to the Reorganization. If a proposed Reorganization is approved, it is expected to take effect on or about September 17, 2010.

Credit Suisse believes that, with respect to each proposed Reorganization, the shareholders of each Fund will benefit more from the potential operating efficiencies and economies of scale that may be achieved by combining the Funds' assets in the Reorganization, than by continuing to operate the two Funds separately. Credit Suisse further believes that it is in the best interests of each Target Fund's shareholders to combine its assets with a Fund that has the same or a lower gross expense structure and the same or a lower net expense structure (i.e., after voluntary fee waivers and expense reimbursements), although the performance history of each Target Fund is generally better than that of the Large Cap Blend Fund. The Large Cap Blend Fund, following completion of one or more of the Reorganizations, may be referred to as the "Combined Fund" in this Combined Prospectus/Proxy Statement. It is anticipated that the gross operating expense ratio for the Combined Fund will be the same as or lower than the current gross operating expense ratio for each Target Fund and that the net operating expense ratio (i.e., after voluntary fee waivers and expense reimbursements) for the Combined Fund will be the same as or lower than the current net operating expense ratio for each Target Fund. Credit Suisse believes that continuing to operate each Target Fund as currently constituted is not in the best interests of the Target Fund's shareholders.

In approving each Reorganization, the relevant Board, including the relevant Independent Trustees/Directors, determined that participation in the Reorganization is in the best interests of the relevant Target Fund and that the interests of the Target Fund's shareholders will not be diluted as a result of the Reorganization. The Board of Directors of the Large Cap Blend Fund also made similar determinations and approved each Reorganization with respect to the Large Cap Blend Fund. The relevant Board considered the Reorganization proposals at a meeting held on May 3, 2010, and at such meeting, the entire Board, including the Independent Trustees/Directors, unanimously approved each relevant Reorganization. The approval determinations were made on the basis of each Trustee's or Director's judgment after consideration of all of the factors taken as a whole, though individual Trustees and Directors may have placed different weight on various factors and assigned different degrees of materiality to various conclusions.

The factors considered by each Board with regard to each applicable Reorganization include, but are not limited to, the following:

• The fact that the investment objectives of the relevant Target Fund and the Large Cap Blend Fund are identical or substantially similar and certain investment strategies of the relevant Target Fund and Large Cap Blend Fund are compatible, while others are different. The Trustees and the Directors

considered the principal differences in investment strategy between the Large Cap Blend Fund and each relevant Target Fund. See "Summary — Investment Objectives and Principal Investment Strategies."

• The possibility that the Combined Fund may achieve certain operating efficiencies and economies of scale from its larger net asset size, such as eliminating multiple sets of prospectuses, reports to shareholders and other documents required if the Target Fund and the Large Cap Blend Fund remained separate.

• The larger Combined Fund asset base could produce portfolio management benefits, such as the ability to command more attention from brokers and underwriters of securities in which the Funds invests than either Fund currently enjoys.

• The expectation that the Combined Fund will have gross operating expenses (i.e., operating expenses before taking into account waivers and reimbursements) the same as or below those of the each Target Fund; and that the Combined Fund will have net operating expenses (i.e., operating expenses after taking into account voluntary fee waivers and expense reimbursement arrangements) the same as or below those of each Target Fund.

• The personnel of Credit Suisse who will manage the Combined Fund. The Directors considered that Credit Suisse will continue to serve as the investment adviser of the Combined Fund after the Reorganization. The Directors further noted that the proposed portfolio managers of the Combined Fund currently manage each of the Target Funds. See "Comparison of the Funds — Management of the Funds."

• The relative performance histories of each Fund over different time periods compared with each other and to the relative benchmarks applicable to each Fund.

• The fact that it is currently anticipated that there will be no gain or loss recognized by shareholders for federal income tax purposes as a result of a Reorganization, as each Reorganization is expected to be a tax-free transaction.

• The fact that Credit Suisse or its affiliates will pay all reasonable, ordinary expenses incurred in connection with each Reorganization.

• The interests of shareholders of each Target Fund will not be diluted as a result of a Reorganization.

• No sales or other charges will be imposed in connection with a Reorganization.

If a Reorganization is not approved by shareholders of the relevant Target Fund, the relevant Board may consider other alternatives. If no such suitable alternatives can be found, the relevant Board may consider the liquidation of such Target Fund. Any such liquidation could be a taxable event for certain shareholders.

Each relevant Board unanimously recommends that you vote "For" the Reorganization relating to your Target Fund.

INVESTMENT OBJECTIVES. The investment objectives of the Large Cap Value Fund and the Large Cap Blend Fund are substantially similar. The investment objective of the Large Cap Value Fund is long-term capital appreciation and continuity of income. The investment objective of the Large Cap Blend Fund is long-term appreciation of capital. Each of the Large Cap Value Fund's and the Large Cap Blend Fund's investment objective may be changed without shareholder approval. The Combined Fund will pursue the Large Cap Blend Fund's investment objective.

PRINCIPAL INVESTMENT STRATEGIES. Under normal market conditions, each Fund invests at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of U.S. companies with large market capitalizations ("large companies"). The Large Cap Value Fund considers a large company to be one that is represented in the Russell Value Index or has similar attributes and capitalization to companies in the Russell Value Index. The Large Cap Blend Fund considers a large company to be one that is represented in the S&P 500 Index or has similar attributes and capitalizations to companies in the S&P 500 Index. As of December 31, 2009, the market capitalizations of companies included in the Russell Value Index were $262.55 million to $322.67 billion and the market capitalizations of companies included in the S&P 500 Index were $1.12 billion to $322.67 billion. In the case of the Large Cap Value Fund, some companies may fall outside the definition of large company after the Large Cap Value Fund has purchased their securities. These companies continue to be considered large for purposes of the Large Cap Value Fund's minimum 80% allocation to large company equities.

Each Fund follows the same quantitative portfolio management techniques rather than a traditional fundamental equity research approach. Each Fund's portfolio managers select securities for the Fund using proprietary quantitative models, which are designed to:

• forecast the expected relative return of stocks by analyzing a number of fundamental factors, including a company's relative valuation, use of capital, balance sheet quality, profitability, realized and expected growth potential and earnings and price momentum,

• identify stocks likely to suffer price declines if market conditions deteriorate and limit the Fund's overall exposure to such low quality stocks, and

• help determine the Fund's relative exposure to different industry sectors by analyzing sector performance under different market scenarios.

The Large Cap Value Fund's portfolio managers apply the proprietary quantitative models to companies that are represented in the Russell Value Index, as well as other

companies with similar attributes and capitalizations to the companies in the Russell Value Index. The Large Cap Blend Fund's portfolio managers apply the proprietary quantitative models to companies that are represented in the S&P 500 Index, as well as other companies with similar attributes and capitalizations to the companies in the S&P 500 Index. A stock may be overweighted or underweighted in relation to the applicable index based on the expected return and risks associated with that stock, both considered relative to the applicable Fund as a whole, among other characteristics. In general, each Fund maintains investment attributes similar to those of the applicable index, and limits its divergence from the applicable index in terms of market, industry and sector exposures.

The portfolio managers of each Fund may sell securities for a variety of reasons such as to realize profits, limit losses, and to take advantage of other investment opportunities.

The Large Cap Blend Fund may engage in active and frequent trading, resulting in high portfolio turnover.

Each Fund's 80% investment policy may be changed by the relevant Board on 60 days' notice to shareholders.

Each Fund primarily invests in common stocks, preferred stocks and securities convertible into common stocks, and the Large Cap Blend Fund also primarily invests in securities whose values are based on common stocks, such as rights and warrants. The Large Cap Value Fund may invest in both listed and unlisted securities. It may also invest up to 10% of its net assets in non-U.S. securities and up to 10% in restricted securities. The Large Cap Blend Fund may invest up to 20% of its net assets in foreign securities, including dollar-denominated ADRs of foreign issuers. To a limited extent, each Fund may also engage in other investment practices. See "Comparison of the Funds — Certain Investment Practices" below.

The Combined Fund's principal investment strategies will be those of the Large Cap Blend Fund.

COMPARISON. The main difference between the Funds is that the Large Cap Value Fund invests principally in large cap value stocks, while the Large Cap Blend Fund invests principally in a blend of large cap value and growth stocks. As noted above, the Large Cap Value Fund maintains investment attributes that are similar to those of the Russell Value Index, while the Large Cap Blend Fund maintains investment attributes that are similar to those of the S&P 500 Index.

While the Large Cap Value Fund and the Large Cap Blend Fund have certain differences in strategies, the Funds pursue substantially similar investment objectives and utilize certain compatible investment strategies.

INVESTMENT OBJECTIVES. The investment objectives of the Mid-Cap Core Fund and the Large Cap Blend Fund are substantially similar. The investment objective of the Mid-Cap Core Fund is maximum capital appreciation. The investment objective of the Large Cap Blend Fund is long-term appreciation of capital. Each of the Mid-Cap Core Fund's and the Large Cap Blend Fund's investment objective may be changed without shareholder approval.

PRINCIPAL INVESTMENT STRATEGIES. Under normal market conditions, the Mid-Cap Core Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities of mid-cap companies. As

noted above, under normal market conditions, the Large Cap Blend Fund invests at least 80% of its assets, plus any borrowings for investment purposes, in equity securities of U.S. large companies. The Mid-Cap Core Fund considers a "mid cap" company to be one that is represented in the S&P 400 Index or has similar attributes and capitalization to companies in the S&P 400 Index. The Large Cap Blend Fund considers a large company to be one that is represented in the S&P 500 Index or has similar attributes and capitalizations to companies in the S&P 500 Index.
