Morgan Stanley
Institutional Fund, Inc.

NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 1997 (UNAUDITED)

Morgan Stanley Institutional Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as an open-end management investment
company.  As of December 31, 1997, the Fund was comprised of 29 separate active,
diversified and non-diversified portfolios (individually referred to as a 
"Portfolio",  collectively as the "Portfolios").  Each Portfolio (with the
exception of the International Small Cap, Money Market and Municipal Money
Market Portfolios) offers two classes of shares - Class A and Class B.  Both
classes of shares have identical voting rights (except shareholders of a Class
have exclusive voting rights regarding any matter relating solely to that Class
of shares), dividend, liquidation and other rights. The U.S. Equity Plus
Portfolio commenced operations on July 31, 1997 and the Asian Real Estate and
European Real Estate Portfolios commenced operations on October 1, 1997.  The
financial statements presented here are for the Asian Real Estate, European Real
Estate and U.S. Equity Plus Portfolios only. 

A.  ACCOUNTING POLICIES: The following significant accounting policies are in
conformity with generally accepted accounting principles for investment
companies.  Such policies are consistently followed by the Fund in the
preparation of the financial statements.  Generally accepted accounting
principles may require management to make estimates and assumptions that affect
the reported amounts and disclosures in the financial statements.  Actual
results may differ from those estimates.

1.  SECURITY VALUATION:  Equity securities listed on a U.S. exchange and equity
securities traded on NASDAQ are valued at the latest quoted sales price on the
valuation date.  Securities listed on a foreign exchange are valued at their
closing price.  Unlisted securities and listed securities not traded on the
valuation date for which market quotations are readily available are valued at
the average of the mean between the current bid and asked prices obtained from
reputable brokers.  Bonds and other fixed income securities may be valued
according to the broadest and most representative market.  In addition, bonds
and other fixed income securities may be valued on the basis of prices provided
by a pricing service which are based primarily on institutional size trading in
similar groups of securities.  Debt securities purchased with remaining
maturities of 60 days or less are valued at amortized cost, if it approximates
market value.  All other securities and assets for which market values are not
readily available, including restricted securities, are valued at fair value as
determined in good faith by the Board of Directors, although the actual
calculations may be done by others.

2.  INCOME TAXES:  It is each Portfolio's intention to qualify as a regulated
investment company and distribute all of its taxable and tax-exempt income. 
Accordingly, no provision for Federal income taxes is required in the financial
statements. 

A Portfolio may be subject to taxes imposed by countries in which it invests. 
Such taxes are generally based on income and/or capital gains earned or
repatriated.  Taxes are accrued and applied to net investment income, net
realized gains and net unrealized appreciation as  income and/or capital gains
are earned.

3.  FOREIGN CURRENCY TRANSLATION AND FOREIGN INVESTMENTS:  The books and records
of the Fund are maintained in U.S. dollars.  Foreign currency amounts are
translated into U.S. dollars at the mean of the bid and asked prices of such
currencies against U.S. dollars last quoted by a major bank as follows:

- -   investments, other assets and liabilities at the
    prevailing rates of exchange on the valuation
    date;

- -   investment transactions and investment income
    at the prevailing rates of exchange on the dates
    of such transactions.

Although the net assets of the Fund are presented at the foreign exchange rates
and market values at the close of the period, the Fund does not isolate that
portion of the results of operations arising as a result of changes in the
foreign exchange rates from the fluctuations arising from changes in the market
prices of the securities held at period end.  Similarly, the Fund does not
isolate the effect of changes in foreign exchange rates from the fluctuations
arising from changes in the market prices of securities sold during the period. 
Accordingly, realized and unrealized foreign currency gains (losses) are
included in the reported net realized and unrealized gains (losses) on
investment transactions and balances.  However, pursuant to U.S. Federal income
tax regulations, gains and losses from certain foreign currency transactions and
the foreign currency portion of gains and losses realized on sales and
maturities of foreign denominated debt securities are treated as ordinary income
for U.S. Federal income tax purposes.  

Net realized gains (losses) on foreign currency transactions represent net
foreign exchange gains (losses) from foreign currency exchange contracts,
disposition of foreign currencies, currency gains or losses realized between the
trade and settlement dates on securities transactions, and the difference
between the amount of investment income and foreign withholding taxes recorded
on the Fund's books and the U.S. dollar equivalent amounts actually received or 
paid.  Net unrealized currency gains (losses) from valuing foreign currency
denominated assets and liabilities at period end exchange rates are reflected as
a component of unrealized appreciation (depreciation) on the Statement of Net
Assets.  The change in net unrealized currency gains (losses) for the period is 
reflected on the Statement of Operations.

Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of U.S. dollar denominated
transactions as a
<PAGE>

result of, among other factors, the possibility of lower levels of 
governmental supervision and regulation of foreign securities markets and the 
possibility of political or economic instability.

Prior governmental approval for foreign investments may be required under
certain circumstances in some countries, and the extent of foreign investments
in domestic companies may be subject to limitation in other countries.  Foreign
ownership limitations also may be imposed by the charters of individual
companies to prevent, among other concerns, violation of foreign investment
limitations.  As a result, an additional class of shares (identified as
"Foreign" in the Statement of Net Assets) may be created and offered for
investment.  The "local" and "foreign" shares' market values may differ.  In the
absence of trading of the foreign shares in such markets at December 31, 1997,
the Portfolios value the foreign shares at the closing exchange price of the
local shares.  Such securities are reflected as fair valued in the Statements of
Net Assets.

4. FOREIGN CURRENCY EXCHANGE CONTRACTS: Certain Portfolios may enter into
foreign currency exchange contracts to attempt to protect securities and related
receivables and payables against changes in future foreign currency exchange
rates.  A foreign currency exchange contract is an agreement between two parties
to buy or sell currency at a set price on a future date.  The market value of
the contract will fluctuate with changes in currency exchange rates.  The
contract is marked-to-market daily and the change in market value is recorded by
the Portfolios as unrealized gain or loss.  The Portfolios record realized gains
or losses when the contract is closed equal to the difference between the value
of the contract at the time it was opened and the value at the time it was
closed.  Risk may arise upon entering into these contracts from the potential
inability of counterparties to meet the terms of their contracts and is
generally limited to the amount of the unrealized gain on the contracts, if any,
at the date of  default.  Risks may also arise from unanticipated movements in
the value of a foreign currency relative to the U.S. dollar.

5.  OTHER:  Security transactions are accounted for on the date the securities
are purchased or sold.  Realized gains and losses on the sale of investment
securities are determined on the identified cost basis.  Dividend income is
recorded on the ex-dividend date (except for certain foreign dividends which may
be recorded as soon as the Fund is informed of such dividends) net of applicable
withholding taxes where recovery of such taxes is not reasonably assured.  
Interest income is recognized on the accrual basis except where collection is in
doubt.  Discounts and premiums on securities purchased are amortized according
to the effective yield method over their respective lives.  Most expenses of the
Fund can be directly attributed to a particular Portfolio.  Expenses which
cannot be directly attributed are apportioned among the Portfolios based upon
relative net assets.  Income, expenses (other than class specific expenses) and
realized and unrealized gains or losses are allocated to each class of shares
based upon their relative net assets.  Distributions for the remaining
Portfolios are recorded on the ex-distribution date.

The amount and character of income and capital gain distributions to be paid by
the Fund are determined in accordance with Federal income tax regulations which 
may differ from generally accepted accounting principles.  These differences are
primarily due to differing book and tax treatments for the character and timing
of the recognition of gains or losses on securities and forward foreign currency
exchange contracts, and the timing of the deductibility of certain foreign
taxes. 

Permanent book and tax basis differences relating to shareholder distributions
may result in reclassifications among undistributed net investment income
(loss), accumulated net realized gain (loss) and paid in capital.

Permanent book and tax differences, if any, are not included in ending
undistributed (distributions in excess of) net investment income/accumulated net
investment loss for the purpose of calculating net investment income (loss) per
share in the Financial Highlights.

B.  ADVISER:  Morgan Stanley Asset Management Inc. (the "Adviser" or "MSAM"), a
wholly-owned subsidiary of Morgan Stanley, Dean Witter, Discover & Co., provides
the Fund with investment advisory services under the terms of an Investment
Advisory and Management Agreement (the "Agreement") at the annual rates of
average daily net assets indicated below.  MSAM has agreed to reduce fees
payable to it and to reimburse the Portfolios, if necessary, if the annual
operating expenses, as defined, expressed as a percentage of average daily net
assets, exceed the maximum ratios indicated as follows:

                                             Maximum
                                           Expense Ratio

     PORTFOLIO        ADVISORY
     ---------           FEE          CLASS A        CLASS B
                         ---          -------        -------
Asian Real Estate        0.80%          1.00%          1.25%
European Real Estate      0.80           1.00           1.25
U.S. Equity Plus          0.45           0.80           1.05


C.  ADMINISTRATOR:  MSAM also provides the Fund with administrative services
pursuant to an administrative agreement for a monthly fee which on an annual
basis equals 0.15% of the average daily net assets of each Portfolio, plus
reimbursement of out-of-pocket expenses.  Under an agreement between MSAM and
The Chase Manhattan Bank ("Chase"), through its affiliate Chase Global Funds
Services Company ("CGFSC"),  Chase provides certain administrative services to
the Fund. For such services, MSAM pays Chase a portion of the fee MSAM receives
from the Fund.  Certain employees of CGFSC are officers of the Fund.  In
addition, the Fund incurs local administration fees in connection with doing
business with certain emerging market countries.

D.  DISTRIBUTOR:  Morgan Stanley & Co., Incorporated (the "Distributor"), a
wholly-owned subsidiary of Morgan Stanley, Dean Witter, Discover & Co., and an
affiliate of MSAM, serves as the distributor of the Fund and provides Class B
shareholders of the applicable Portfolios with distribution services pursuant to
a Distribution Plan (the "Plan") in accordance with Rule 12b-1 under the
Investment Company Act of 1940.
<PAGE>

Under the Plan, the Distributor is entitled to receive from each Portfolio, a
distribution fee, which is accrued daily and paid quarterly, at an annual rate
