                        Investment Objective and Policy

MassMutual Corporate Investors, a closed-end investment company, was offered to
the public in September 1971 and its shares are listed on the New York Stock
Exchange. The share price of Corporate Investors can be found in the financial
section of most newspapers as "MassCp" or "MassMuInv" under the New York Stock
Exchange listings. The trading symbol is "MCI".

The Trust's investment objective is to maintain a portfolio of securities
providing a fixed yield and at the same time offering an opportunity for capital
gains. The principal investments are long-term corporate debt obligations and
occasionally preferred stocks purchased directly from issuers. These provide a
fixed yield and potential capital gains through warrants, conversion rights, or
other equity features which are a prerequisite to every private placement
purchased.

The Trust holds investments in a number of companies that are not publicly
traded at this time. Capital gains may be realized on holdings of private
companies through various methods, including directly negotiated sales, put
options and initial public offerings of stock.

The Trust pays quarterly dividends and intends to distribute substantially all
of its net income to shareholders each year. All distributions are paid in cash
unless the shareholder elects to participate in the Dividend Reinvestment and
Share Purchase Plan.

Dividends are distributed in January, May, August, and November.



To Our Shareholders

                                                                October 31, 2002

We are pleased to present the September 30, 2002 Quarterly Report of MassMutual
Corporate Investors. The Board of Trustees declared a quarterly dividend of 36
cents per share, payable on November 14, 2002 to shareholders of record on
October 31, 2002. A dividend of 43 cents per share was paid in the previous
quarter.

The financial markets continued to decline during the third quarter. For the
quarter, the Dow Jones Industrial Average declined 17.43%, the sharpest
quarterly decline since the fourth quarter of 1987. The S&P 500 and Russell 2000
Indices had similar drops, declining 17.27% and 21.40%, respectively, during the
third quarter.

Fixed income markets continue to be mixed with higher quality indices up for the
quarter. On one hand, the Lehman Intermediate Government/Credit Bond Index and
the Lehman Government/Credit Bond Index both posted solid increases of 4.53% and
5.70%, respectively, for the quarter. On the other hand, high yield indices were
down significantly. For example, the Merrill Lynch High Yield Master II Index
declined 3.02% for the third quarter.

For the quarter ended September 30, 2002, the Trust earned 38 cents per share
compared to 43 cents per share in the previous quarter. Net assets of the Trust
as of September 30th were $173,375,477 or $19.71 per share compared to
$179,984,179 or $20.51 per share on June 30, 2002. This translated into a
negative 1.84% return for the quarter, based on change in net assets with
reinvestment of dividends.

During the quarter, two new private placement securities, totaling approximately
$4.5 million were added to the Trust's portfolio. The Trust purchased the
securities of C&M Conveyor and Shelter Acquisition, Inc. The weighted average
coupon of these investments was 11.1%. (A brief description of these investments
can be found in the Schedule of Investments.)

As noted in past press releases, quarterly earnings of the Trust have been
declining. The decline in earnings is generally attributable to a decline in
interest rates and to the weak economic environment which has adversely impacted
the ability of some borrowers to pay their obligations. Due to this decline in
earnings, the Trustees voted to reduce the Trust's dividend to 36 cents per
share.

Thank you for your continued interest in and support of MassMutual Corporate
Investors.

Sincerely,




Robert E. Joyal
President

1. HISTORY

   MassMutual Corporate Investors (the "Trust") is a closed-end, non-diversified
   investment company. David L. Babson & Company Inc. ("Babson"), a majority
   owned subsidiary of Massachusetts Mutual Life Insurance Company,
   ("MassMutual"), acts as its investment adviser.

   The Trust commenced operations in 1971 as a Delaware corporation. Pursuant to
   an Agreement and Plan of Reorganization dated November 14, 1985, approved by
   shareholders, the Trust was organized as a Massachusetts business trust under
   the laws of the Commonwealth of Massachusetts, effective November 28, 1985.

   On January 27,1998, the Board of Trustees authorized the formation of a
   wholly-owned subsidiary ("MMCI Subsidiary Trust") for the purpose of holding
   certain investments. The results of MMCI Subsidiary Trust have been
   consolidated in the accompanying financial statements.

2. SIGNIFICANT ACCOUNTING POLICIES

   The following is a summary of significant accounting policies followed
   consistently by the Trust in the preparation of the 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
   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 directly negotiated transaction to a limited number of purchasers or in
   a public offering for which a registration statement is in effect under the
   Securities Act of 1933.

   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 Board of Trustees of the Trust (the "Trustees"). Each restricted
   security is valued by the Trustees at the time of the acquisition thereof 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 the security by
   the Trust; an estimate of the existence and 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; 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. 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS        MASSMUTUAL CORPORATE INVESTORS
(CONTINUED)

   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 Securities Act of 1933
   and any other developments which are likely to increase the probability that
   the securities may be publicly sold by the Trust without restriction.

   The Board of Trustees of the Trust meets at least once in each quarter to
   value 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 (otherwise than as
   Trustees) or of Babson. In making valuations, the Trustees will consider
   reports by Babson analyzing each portfolio security in accordance with the
   relevant factors referred to above. Babson has agreed to provide such reports
   to the Trust at least quarterly.

   The financial statements include restricted securities valued at $170,590,994
   (98.39% of net assets) as of September 30, 2002 ($165,661,462 at September
   30, 2001) whose values have been estimated by the Board of 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 corporate public securities are stated at the last reported
   sales price or at prices based upon quotations obtained from brokers and
   dealers as of September 30, 2002, 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.

   B. ACCOUNTING FOR INVESTMENTS:

   Investment transactions are accounted for on trade date. Dividend income is
   recorded on the ex-dividend date. Interest income is recorded on the accrual
   basis.

   The Trust has elected to accrue, for financial reporting purposes, certain
   premiums and discounts which are required to be accrued for federal income
   tax purposes.

   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.

   The Trust does not accrue income when payment is delinquent and when
   management believes payment is questionable.

   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:

   No provision for federal taxes on net investment income and short-term
   capital gains is considered necessary because 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 to the Trustees
   either to designate the net realized long-term gains as undistributed and to
   pay the federal capital gains taxes thereon or to distribute all or a portion
   of such net gains.

3. MANAGEMENT FEE

   Under an investment services contract, Babson has agreed to invest for
   MassMutual Life Insurance Company's ("MassMutual") general account
   concurrently with the Trust in each restricted security purchased by the
   Trust. Babson, in addition to originating and sharing in the purchase of such
   securities, 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. Babson provides a continuing
   review of the investment operations of the Trust. Babson also 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.

   Under the investment services contract, as amended July 1, 1988, the Trust
   pays Babson a quarterly base rate (the "Base Fee Rate") of 5/16 of 1% of the
   value of the Trust's net assets as of the end of each fiscal quarter,
   approximately equivalent to 1.25% of the net asset value of the Trust on an
   annual basis, plus or minus a quarterly performance adjustment (the
   "Performance Adjustment") of up to 1/16 of 1% approximately equivalent to
   .25% on an annual basis.

   The Performance Adjustment is based on the Trust's performance as compared to
   a benchmark rate of return (the "Target Rate") equal to 5.0 percentage points
   plus an unweighted, arithmetic average of the rates of return on the Standard
   & Poor's Industrial Stock Price Index and the Lehman Brothers Intermediate
   Credit Bond Index (formerly called the Lehman Brothers Intermediate Corporate
   Bond Index) over a rolling three-year period (the "Measurement Period")
   comprising the twelve quarters ending on the last day of each quarter (the
   "Valuation Date"). The Performance Adjustment is equal to 5% of the
   difference between the Trust's actual rate of return over the Measurement
   Period and the Target Rate. If the Trust's actual rate of return exceeds the
   Target Rate, the Base Fee Rate is increased by an amount equal to the
   Performance Adjustment; if the Trust's actual rate of return is less than the
   Target Rate, the Base Fee Rate is reduced by the Performance Adjustment. The
   advisory fee payable by the Trust is equal to the Base Fee Rate (as adjusted
   by the Performance Adjustment) times the net asset value of the Trust as of
   the Valuation Date. The Performance Adjustment for the quarters ended March
   31, June 30, and September 30, 2002 was:

                                PERFORMANCE

                                 ----------      ------
           March 31, 2002          0.0625%      $114,090
           June 30, 2002           0.0625%      $112,914
           September 30, 2002      0.0625%      $108,793

4. SENIOR SECURED INDEBTEDNESS

   A. NOTE PAYABLE

   MassMutual holds the Trust's $20,000,000 Senior Fixed Rate Convertible Note
   (the "Note") issued by the Trust in 1995. The Note, as amended, is due
   November 15, 2007 and accrues at 7.39% per annum. The Noteholder, 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 each of the periods
   ended September 30, 2002 and 2001, the Trust incurred total interest expense
   on the Note of $1,108,500.

   B. REVOLVING CREDIT AGREEMENT

   The Trust entered into a Revolving Credit Agreement with Fleet National Bank
   as of June 29, 2000, in the principal amount of $25,000,000, maturing on May
   31, 2005. The interest rate on the outstanding revolving loan is determined
   for periods of one, three or six months (as selected by the Trust) and is set
   at an annual rate equal to LIBOR (London Interbank Offered Rate) plus 0.37%.
   The Trust also agreed to pay an up-front fee equal to 0.10% on the total
   commitment. The facility fee is 0.15% per annum of the total commitment.

   As of September 30, 2002 and 2001, there were no outstanding loans drawn
   against the revolving credit facility. For each of the periods ended
   September 30, 2002 and 2001, the Trust incurred $27,945 in expense related to
   the undrawn portion.

                  DIVIDEND REINVESTMENT AND SHARE PURCHASE PLAN

MassMutual Corporate Investors offers a Dividend Reinvestment and Share Purchase
Plan. The Plan provides a simple 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. A shareholder may join the Plan by filling out and mailing an
authorization card to Shareholder Financial Services, Inc., the Transfer Agent.
Participating shareholders will continue to participate until they notify the
Transfer Agent, in writing, of their desire to terminate participation. Unless a
shareholder elects to participate in the Plan, he or she will, in effect, have
elected to receive dividends and distributions in cash.

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 $10 nor more than $5,000 per quarter.

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 any way, 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.)

Any questions regarding the Plan should be addressed to Shareholder Financial
Services, Inc., Agent for MassMutual Corporate Investors' Dividend Reinvestment
and Share Purchase Plan, P.O. Box 173673, Denver CO 80217-3673.
