The Trust's share price can be found in the financial section of most newspapers as "MassPrt" or "MassMuPrt" under the New York Stock Exchange listings or Closed-End Fund Listings. The Trust's investment objective is to maximize total return by providing a high level of current income, the potential for growth of income, and capital appreciation. The Trust's principal investments are privately placed, below-investment grade, long-term debt obligations purchased directly from their issuers, which tend to be smaller companies. At least half of these investments normally include equity features such as common stock, warrants, conversion rights, or other equity features that provide the Trust with the opportunity to realize capital gains. The Trust will also invest in publicly traded debt securities (including high yield securities), again with an emphasis on those with equity features, and in convertible preferred stocks and, subject to certain limitations, readily marketable equity securities. Below-investment grade or high yield securities have predominantly speculative characteristics with respect to the capacity of the issuer to pay interest and repay principal. In addition, the Trust may temporarily invest in high quality, readily marketable securities. Babson Capital Management LLC ("Babson Capital") manages the Trust on a total return basis. The Trust distributes substantially all of its net income to shareholders each year. Accordingly, the Trust pays dividends to shareholders in January, May, August, and November. All registered shareholders are automatically enrolled in the Dividend Reinvestment and Cash Purchase Plan unless cash distributions are requested. FORM N-Q The Trust files its complete schedule of portfolio holdings with the U.S. Securities and Exchange Commission ("SEC") for the first and third quarters of each fiscal year on Form N-Q. This information is available (i) on the SEC's website at http://www.sec.gov; and (ii) at the SEC's Public Reference Room in Washington, DC (which information on their operation may be obtained by calling 1-800-SEC-0330).

MPV Listed NYSE MassMutual Participation Investors TO OUR SHAREHOLDERS April 30, 2009 We are pleased to present the March 31, 2009 Quarterly Report of MassMutual Participation Investors (the "Trust"). At the Trust's Quarterly Board of Trustees Meeting, which was held on January 23, 2009, the Trustees announced that Roger W. Crandall had stepped down as Trustee and Chairman of the Board of Trustees as a result of his new position as President and Chief Operating Officer of Massachusetts Mutual Life Insurance Company ("MassMutual"). Subsequently, Clifford M. Noreen, former President of the Trust, was appointed as a Trustee and elected to succeed Mr. Crandall as Chairman of the Board of Trustees. Mr. Noreen is considered an "Interested Person" of the Trust as defined by the Investment Company Act of 1940. Mr. Noreen currently serves as President of Babson Capital Management LLC ("Babson"), the Trust's investment advisor. The Board of Trustees elected me to succeed Mr. Noreen as President of the Trust at their January 23, 2009 meeting. I was previously a Vice President of the Trust, and am currently the co-head of the Mezzanine & Private Equity Group at Babson, where I jointly oversee all of the group's activities. I have been with Babson and its predecessor organization since 1988. I look forward to serving as President of the Trust. The Board of Trustees declared a quarterly dividend of 25 cents per share, payable on May 18, 2009 to shareholders of record on May 4, 2009. The Trust had paid a 25 cent per share dividend for the preceding quarter. U.S. equity markets, as approximated by the Russell 2000 Index, decreased 14.95% for the quarter. U.S. fixed income markets, as approximated by the Barclays Capital U.S. Corporate High Yield Index increased 5.98% for the quarter. The ongoing turmoil in the financial markets continues to have an adverse effect on middle market buyout activity. Leveraged loan volume in the first quarter of 2009 was as low as it has been in recorded history. With senior lending capacity so limited, our deal flow has been sluggish. During the quarter, we closed on one new investment and have a few transactions that are nearing completion. Beyond that, however, our transaction backlog is very low and we do not expect a significant pickup in investment activity for the foreseeable future. On the positive side, the few transactions we have completed or are about to complete have been more conservatively structured and attractively priced than has been the market norm for the past few years. We continue to spend considerable time working with our portfolio companies as the current economic conditions and the difficult banking environment negatively impact the ability of some of our borrowers to pay their obligations. During the quarter, the Trust made a private placement investment in one new issuer totaling approximately $1.3 million. The new issuer was Sencore Holding Company. (A brief description of this investment can be found in the Consolidated Schedule of Investments.) During the quarter ended March 31, 2009, net assets of the Trust decreased to $105,445,089 or $10.62 per share compared to $110,175,930 or $11.10 per share on December 31, 2008, which translates into a -4.32% total return for the quarter, based on the change in the Trust's net assets assuming the reinvestment of all dividends. Long term, the Trust returned -10.15%, 3.55%, 11.52% and 10.66% for the 1-, 3-, 5- and 10-year time periods, respectively, based on the change in the Trust's net assets assuming the reinvestment of all dividends. The Trust earned 27 cents per share of net investment income for the quarter, compared to 26 cents per share in the previous quarter. During the quarter ended March 31, 2009, the market price of the Trust decreased 6.08% from $9.05 per share to $8.50 per share. The Trust's market price of $8.50 per share equates to a 19.96% discount to the March 31, 2009 net asset value per share. The Trust's average quarter-end premium for the 3, 5 and 10-year periods was 11.6%, 10.9% and 6.5%, respectively.

HISTORY MassMutual Participation Investors (the "Trust") was organized as a Massachusetts business trust under the laws of the Commonwealth of Massachusetts pursuant to a Declaration of Trust dated April 7, 1988. The Trust is a diversified closed-end management investment company. Babson Capital Management LLC ("Babson Capital"), a wholly-owned indirect subsidiary of Massachusetts Mutual Life Insurance Company ("MassMutual"), acts as its investment adviser. The Trust's investment objective is to maximize total return by providing a high level of current income, the potential for growth of income, and capital appreciation. The Trust's principal investments are privately placed, below-investment grade, long-term debt obligations purchased directly from their issuers, which tend to be smaller companies. At least half of these investments normally include equity features such as common stock, warrants, conversion rights, or other equity features that provide the Trust with the opportunity to realize capital gains. The Trust will also invest in publicly traded debt securities (including high yield securities), again with an emphasis on those with equity features, and in convertible preferred stocks and, subject to certain limitations, readily marketable equity securities. Below-investment grade or high yield securities have predominantly speculative characteristics with respect to the capacity of the issuer to pay interest and repay capital. In addition, the Trust may temporarily invest in high quality, readily marketable securities. On January 27, 1998, the Board of Trustees authorized the formation of a wholly-owned subsidiary of the Trust ("MMPI Subsidiary Trust") for the purpose of holding certain investments. The results of the MMPI Subsidiary Trust are consolidated in the accompanying financial statements. Footnote 2.D below discusses the federal tax consequences of MMPI Subsidiary Trust. 2. SIGNIFICANT ACCOUNTING POLICIES The following is a summary of significant accounting policies followed consistently by the Trust in the preparation of its consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. A. VALUATION OF INVESTMENTS: Valuation of a security in the Trust's portfolio is made on the basis of the market price whenever market quotations are readily available and all securities of the same class held by the Trust can be readily sold in such market. Nearly all securities which are acquired by the Trust directly from the issuers and shares into which such securities may be converted or which may be purchased on the exercise of warrants attached to such securities will be subject to legal or contractual delays in, or restrictions on, resale and will therefore be "restricted securities." Generally speaking, as contrasted with open-market sales of unrestricted securities, which may be effected immediately if the market is adequate, restricted securities can be sold only in a public offering for which a registration statement is in effect under the Securities Act of 1933, as amended (the "1933 Act") or pursuant to a transaction that is exempt from registration under the 1933 Act. The value of restricted securities, and of any other assets for which there are no reliable market quotations, is the fair value as determined in good faith by the Trust's Board of Trustees (the "Trustees"). Each restricted security is valued by the Trustees at the time of its acquisition and at least quarterly thereafter. The Trustees have established guidelines to aid in the valuation of each security. Generally, restricted securities are initially valued at cost or less at the time of acquisition by the Trust. Values greater or less than cost are used thereafter for restricted securities in appropriate circumstances. Among the factors ordinarily considered are the existence of restrictions upon the sale of a security held by the Trust; an estimate of the existence and the extent of a market for the security; the extent of any discount at which the security was acquired; the estimated period of time during which the security will not be freely marketable; the estimated expenses of registering or otherwise qualifying the security for public sale; estimated underwriting commissions if underwriting would be required to effect a sale; in the case of a convertible security, whether or not it would trade on the basis of its stock equivalent; in the case of a debt obligation which would trade independently of any equity equivalent, the current yields on comparable securities; the estimated amount of the floating supply of such securities available for purchase; the proportion of the issue held by the Trust; changes in the financial condition and prospects of the issuer; the existence of merger proposals or tender offers affecting the issuer; and any other factors affecting fair value, all in accordance with the Investment Company Act of 1940, as amended (the "1940 Act"). In making valuations, opinions of counsel may be relied upon as to whether or not securities are restricted securities and as to the legal requirements for public sale. When market quotations are readily available for unrestricted securities of an issuer, restricted securities of the same class are generally valued at a discount from the market price of such unrestricted securities. The Trustees, however, consider all factors in fixing any discount, including the filing of a registration statement for such securities under the 1933 Act and any other developments which are likely to increase the probability that the securities may be publicly sold by the Trust without restriction. The Trustees meet at least once each quarter to approve the value of the Trust's portfolio securities as of the close of business on the last business day of the preceding quarter. This valuation requires the approval of a majority of the Trustees of the Trust, including a majority of the Trustees who are not interested persons of the Trust or of Babson Capital. In making valuations, -------------------------------------------------------------------------------- 35 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) (Unaudited) the Trustees will consider reports by Babson Capital analyzing each portfolio security in accordance with the relevant factors referred to above. Babson Capital has agreed to provide such reports to the Trust at least quarterly. The consolidated financial statements include private placement restricted securities valued at $91,719,502 (86.98% of net assets) as of March 31, 2009 whose values have been estimated by the Trustees in the absence of readily ascertainable market values. Due to the inherent uncertainty of valuation, those estimated values may differ significantly from the values that would have been used had a ready market for the securities existed, and the differences could be material. The values for Rule 144A restricted securities and corporate public securities are stated at the last reported sales price or at prices based upon quotations obtained from brokers and dealers as of March 31, 2009, subject to discount where appropriate, and are approved by the Trustees. Short-term securities with more than sixty days to maturity are valued at fair value and short-term securities having a maturity of sixty days or less are valued at amortized cost, which approximates market value. Effective January 1, 2008, the Trust adopted FASB Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"). FAS 157 clarifies the definition of fair value, establishes a framework for measuring fair values and requires additional disclosures about the use of fair value measurements. FAS 157 requires companies to provide expanded information about the assets and liabilities measured at fair value and the potential effect of these fair valuations on an entity's financial performance. Various inputs are used in determining the value of the Trust's investments. Using the hierarchy established under FAS 157, these inputs are summarized in the three broad levels listed below: Level 1: quoted prices in active markets for identical securities Level 2: other significant observable inputs (including quoted prices for similar securities, interest rates, prepayments speeds, credit risk, etc.) Level 3: significant unobservable inputs (including the Trust's own assumptions in determining the fair value of investments) The inputs and methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The following is a summary of the inputs used to value the Trust's net assets as of March 31, 2009: ASSETS TOTAL LEVEL 1 LEVEL 2 LEVEL 3 ----------------------------------------------------------------------------- Restricted Securities $95,043,121 $ -- $ 3,323,619 $91,719,502 Public Securities 16,827,587 302,494 16,525,093 -- Short-term Securities 1,980,000 -- 1,980,000 -- ----------------------------------------------------------------------------- TOTAL $113,850,708 $302,494 $21,828,712 $91,719,502 Following is a reconciliation of Level 3 assets for which significant unobservable inputs were used to determine fair value: RESTRICTED PUBLIC SHORT-TERM ASSETS SECURITIES SECURITIES SECURITIES TOTAL ----------------------------------------------------------------------------- Beginning balance at 12/31/2008 $97,424,749 $ -- $ -- $97,424,749 Total gains or losses (realized/unrealized) included in earnings* (7,547,321) -- -- (7,547,321) Purchases, sales, issuances & settlements (net) 1,842,074 -- -- 1,842,074 Transfers in and / or out of Level 3 -- -- -- -- ----------------------------------------------------------------------------- ENDING BALANCE at 3/31/09 $91,719,502 $ -- $ -- $91,719,502 *The amount of net losses for the period included in earnings attributable to the change in unrealized gains or losses relating to Level 3 assets still held at 03/31/09 is $(7,819,842). B. ACCOUNTING FOR INVESTMENTS: Investment transactions are accounted for on the trade date. Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis, including the amortization of premiums and accretion of discounts on bonds held using the yield-to-maturity method. The Trust does not accrue income when payment is delinquent and when management believes payment is questionable. Realized gains and losses on investment transactions and unrealized appreciation and depreciation of investments are reported for financial statement and federal income tax purposes on the identified cost method. -------------------------------------------------------------------------------- 36 MassMutual Participation Investors NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) (Unaudited) C. USE OF ESTIMATES: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. D. FEDERAL INCOME TAXES: The Trust has elected to be taxed as a "regulated investment company" under the Internal Revenue Code, and intends to maintain this qualification and to distribute substantially all of its net taxable income to its shareholders. In any year when net long-term capital gains are realized by the Trust, management, after evaluating the prevailing economic conditions, will recommend that Trustees either designate the net realized long-term gains as undistributed and pay the federal capital gains taxes thereon, or distribute all or a portion of such net gains. The Trust is taxed as a regulated investment company and is therefore limited as to the amount of non-qualified income that it may receive as the result of operating a trade or business, e.g. the Trust's PRO RATA share of income allocable to the Trust by a partnership operating company. The Trust's violation of this limitation could result in the loss of its status as a regulated investment company, thereby subjecting all of its net income and capital gains to corporate taxes prior to distribution to its shareholders. The Trust, from time-to-time, identifies investment opportunities in the securities of entities that could cause such trade or business income to be allocable to the Trust. The MMPI Subsidiary Trust (described in Footnote 1, above) was formed in order to allow investment in such securities without adversely affecting the Trust's status as a regulated investment company. The MMPI Subsidiary Trust is not taxed as a regulated investment company. Accordingly, prior to the Trust receiving any distributions from the MMPI Subsidiary Trust, all of the MMPI Subsidiary Trust's taxable income and realized gains, including non-qualified income and realized gains, is subject to taxation at prevailing corporate tax rates. For the three months ended March 31, 2009, the MMPI Subsidiary Trust has not accrued any income tax expense. In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB Interpretation No. 48, ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES - AN INTERPRETATION OF FASB STATEMENT NO. 109 ("FIN 48"). Management has analyzed the Trust's tax positions taken on federal income tax returns for all open tax years and has concluded that as of March 31, 2009, no provision for uncertain income tax positions would be required in the Trust's financial statements. The Trust's federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue. E. DISTRIBUTIONS TO SHAREHOLDERS: The Trust records distributions to shareholders from net investment income and net realized gains, if any, on the ex-dividend date. The Trust's net investment income dividend is declared four times per year, in April, July, October, and December. The Trust's net realized capital gain distribution, if any, is declared in December. F. EXPENSE REDUCTION: Citibank, N.A. ("Citibank") serves as custodian to the Trust. Pursuant to the custodian agreement, Citibank receives a fee reduced by credits on cash balances the Trust maintains with Citibank. All credit balances, if any, used to reduce the Trust's custodian fees are reported as fees paid indirectly on the Statement of Operations. For the three months ended March 31, 2009, there were no credit balances used to reduce custodian fees. 3. INVESTMENT ADVISORY AND ADMINISTRATIVE SERVICES CONTRACT A. SERVICES: Under an Investment Advisory and Administrative Services Contract (the "Contract") with the Trust, Babson Capital has agreed to use its best efforts to present to the Trust a continuing and suitable investment program consistent with the investment objectives and policies of the Trust. Babson Capital represents the Trust in any negotiations with issuers, investment banking firms, securities brokers or dealers and other institutions or investors relating to the Trust's investments. Under the Contract, Babson Capital also provides administration of the day-to-day operations of the Trust and provides the Trust with office space and office equipment, accounting and bookkeeping services, and necessary executive, clerical and secretarial personnel for the performance of the foregoing services. B. FEE: For its services under the Contract, Babson Capital is paid a quarterly investment advisory fee equal to 0.225% of the value of the Trust's net assets as of the last business day of each fiscal quarter, an amount approximately equivalent to 0.90% on an annual basis. A majority of the Trustees, including a majority of the Trustees who are not interested persons of the Trust or of Babson Capital, approve the valuation of the Trust's net assets as of such day. 4. SENIOR SECURED INDEBTEDNESS MassMutual holds the Trust's $12,000,000 Senior Fixed Rate Convertible Note (the "Note") issued by the Trust in 1995. The Note, as amended, is due December 13, 2011 and accrues -------------------------------------------------------------------------------- 37 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) (Unaudited) interest at 5.80% per annum. MassMutual, at its option, can convert the principal amount of the Note into common shares. The dollar amount of principal would be converted into an equivalent dollar amount of common shares based upon the average price of the common shares for ten business days prior to the notice of conversion. For the three months ended March 31, 2009, the Trust incurred total interest expense on the Note of $174,000. The Trust may redeem the Note, in whole or in part, at the principal amount proposed to be redeemed together with the accrued and unpaid interest thereon through the redemption date plus a Make Whole Premium. The Make Whole Premium equals the excess of (i) the present value of the scheduled payments of principal and interest which the Trust would have paid but for the proposed redemption, discounted at the rate of interest of U.S. Treasury obligations whose maturity approximates that of the Note plus 0.50% over (ii) the principal of the Note proposed to be redeemed. 5. PURCHASES AND SALES OF INVESTMENTS FOR THE THREE MONTHS ENDED 3/31/2009 COST OF PROCEEDS FROM INVESTMENTS SALES OR ACQUIRED MATURITIES -------- ---------- Corporate restricted securities $3,273,194 $1,054,247 Corporate public securities 2,142,152 868,491 The aggregate cost of investments is substantially the same for financial reporting and federal income tax purposes as of March 31, 2009. The net unrealized depreciation of investments for financial reporting and federal tax purposes as of March 31, 2009 is $23,804,196 and consists of $7,987,072 appreciation and $31,791,268 depreciation. -------------------------------------------------------------------------------- 38 MassMutual Participation Investors This page is intentionally left blank This page is intentionally left blank This page is intentionally left blank DIVIDEND REINVESTMENT AND CASH PURCHASE PLAN MassMutual Participation Investors offers a Dividend Reinvestment and Cash Purchase Plan. The Plan provides a simple and automatic way for shareholders to add to their holdings in the Trust through the receipt of dividend shares issued by the Trust or through the reinvestment of cash dividends in Trust shares purchased in the open market. The dividends of each shareholder will be automatically reinvested in the Trust by Shareholder Financial Services Inc., the Transfer Agent, in accordance with the Plan, unless such shareholder elects not to participate by providing written notice to the Transfer Agent. A shareholder may terminate his or her participation by notifying the Transfer Agent in writing. Participating shareholders may also make additional contributions to the Plan from their own funds. Such contributions may be made by personal check or other means in an amount not less than $100 nor more than $5,000 per quarter. Cash contributions must be received by the Transfer Agent at least five days (but no more then 30 days) before the payment date of a dividend or distributions. Whenever the Trust declares a dividend payable in cash or shares, the Transfer Agent, acting on behalf of each participating shareholder, will take the dividend in shares only if the net asset value is lower than the market price plus an estimated brokerage commission as of the close of business on the valuation day. The valuation day is the last day preceding the day of dividend payment. When the dividend is to be taken in shares, the number of shares to be received is determined by dividing the cash dividend by the net asset value as of the close of business on the valuation date or, if greater than net asset value, 95% of the closing share price. If the net asset value of the shares is higher than the market value plus an estimated commission, the Transfer Agent, consistent with obtaining the best price and execution, will buy shares on the open market at current prices promptly after the dividend payment date. The reinvestment of dividends does not, in anyway, relieve participating shareholders of any federal, state or local tax. For federal income tax purposes, the amount reportable in respect of a dividend received in newly-issued shares of the Trust will be the fair market value of the shares received, which will be reportable as ordinary income and/or capital gains. As compensation for its services, the Transfer Agent receives a fee of 5% of any dividend and cash contribution (in no event in excess of $2.50 per distribution per shareholder.)
