LETTER TO SHAREHOLDERS
- --------------------------------------------------------------------------------

We are pleased to present you with this semi-annual report for the BT
Institutional Asset Management Fund (the "Fund"), providing a review of the
markets, the Portfolio, and our outlook, as well as a complete financial summary
of the Fund's operations and a listing of the Portfolio's holdings.

The Fund returned 19.25% for the semi-annual period ended September 30, 1997*,
as compared to 16.93% for the Asset Allocation Index-Long Range**, 26.26% for
the S&P 500 Index**, and 7.05% for the Salomon Broad Investment Grade (BIG)
Index**.  The Lipper Flexible Portfolio Average+ had a return of 17.99% for the
same period.  Since its inception on September 16, 1993, the Fund delivered a
total return of 69.13% cumulatively, or 13.90% annualized, as of September 30,
1997.   The Fund returned 28.13% for the year ended September 30, 1997.

MARKET ACTIVITY
U.S. MARKETS
Economic growth in the first quarter of the Fund's fiscal year was a strong
3.6%, and then it slowed in the next quarter to an estimated 2.8%.  The
inflation picture, which was already quite benign, improved even further.  In
fact, talk of potential deflation even appeared on the scene.   Given this
scenario, the Federal Reserve Board opted to maintain its tight monetary policy
during these months, holding its target for the federal funds rate at 5.5%.  We
believe this suggests that any further tightening will occur only after
inflationary pressures become more evident.

- --------------------------------------------------------------------------------
                                      OBJECTIVE
Seeks a high total return with reduced risk over the long term by allocating
investments among stocks, bonds and short-term instruments.

- --------------------------------------------------------------------------------

Strong economic growth combined with a lack of inflation proved to be positive
for both the equity and bond markets, although there was a short-lived
correction in each during the period, as questions were raised concerning the
possibility of emerging inflation.

U.S. EQUITIES
After a correction of approximately 10% between early March and mid-April, the
S&P 500 Index rebounded and advanced by a huge 17.4% for the second calendar
quarter.  The combination of impressive gains in corporate profits, despite the
absence of pricing power, along with the lack of evident inflation supported the
market's rise to record levels.  The Dow Jones Industrial Average broke the 8000
mark on July 17, and the S&P 500 Index moved to a record level on August 4.  The
Index fell back for the rest of August, swung back once more and almost
recovered to a new peak at the end of September.  Even with that impressive
performance, smaller stocks, as represented by the Russell 2000 Index, recovered
from its March/April bear market even more strongly.  For the period from May
through September 1997, small cap stocks outperformed both the midcap and large
cap segments of the market and broke records virtually every day in September.  

- --------------------------------------------------------------------------------
                                INVESTMENT INSTRUMENTS
Primarily common stocks, corporate and government issued intermediate to 
long-term bonds, various government agency issued asset-backed securities and 
all types of domestic and foreign securities and money market instruments.

U.S. BONDS
The bond market, too, was strong during this semi-annual period overall.

The U.S. Treasury market rallied through most of both quarters, with yields 
closing 0.60% to 0.80% below opening levels.  Continued benign inflation and 
controlled economic growth, put the market's expectations of Federal Reserve 
Board activity on hold and supported the rally in the second calendar 
quarter. In the next quarter, the economy continued to grow at a reasonably 
good rate, while inflation remained muted--a now familiar combination.  
However, a stronger-than-expected employment release in early August, 
combined with the digestion of the $38 billion Treasury Refunding, 
interrupted the rally mid-quarter, and the bond market trended irregularly 
higher before rates resumed their fall at the end of the quarter.

INTERNATIONAL MARKETS
Most of the world's developed equity markets came roaring back in September,
shaking off summer doldrums and returning to their record-setting pace set
through most of the past twelve months amidst a backdrop of sustainable economic
growth and historically low inflation.  So, too, international bonds lagged the
U.S. by only 0.29% in the second calendar quarter, as domestic issues in several
major markets at least partially offset the positive tone provided by the U.S. 
And in the third calendar quarter, international bonds pre-

DIVERSIFICATION OF PORTFOLIO INVESTMENTS
- --------------------------------------------------------------------------------

                       By Asset Class as of September 30, 1997
                       (percentages are based on market value)

                                       [CHART]

Stocks 70%
Bonds 30%


This diversification pie chart shows the Fund's investment exposure to different
asset classes (i.e. stocks, bonds and cash) based on the risk characteristics of
the asset class rather than the actual instrument. For example, the Fund may buy
or sell a futures contract to increase or decrease the Fund's exposure to the
stock market.


cisely matched the performance of the U.S. fixed income market.  With U.S.
Federal Reserve Board policymakers on hold for the time being and renewed
confidence that European economic and monetary convergence will occur, a
supportive environment for both bond and stock markets remains in place.

More specifically, Europe as a whole did not beat the surging U.S. market in the
six months ended September 30, 1997.  However, several of the individual
European equity markets did outperform the S&P 500 Index, even in dollar terms,
in spite of the strength of the U.S. dollar; these included Finland, Italy, and
Spain.  Strong bond market performances came from several of these same
peripheral European nations, as the market came to accept that these economies
will most likely participate in the first round of European Monetary Union in
1999. 

The Japanese stock market continued its pattern of offering great promise and
profound disappointment.  The Nikkei skyrocketed to its year high in the second
calendar quarter, as unexpectedly strong fiscal year 1996 earnings buoyed the
market.  And then in the third calendar quarter, Japan was the poorest
performing major EAFE market.  Several equity markets elsewhere in Asia also saw
precipitous falls, as the Thai currency crisis set off in July sent the region
into a tailspin from which it has yet to recover.  This currency crisis also
sent several of the Southeast Asian debt markets reeling.  Japanese bond returns
lagged the other international markets on a fully-hedged basis.

Canada continued its strong performance both in stocks and bonds, reflecting its
growing, low inflation economy.  Although the Bank of Canada has indicated that
further interest rate moves may be necessary to contain inflationary pressure,
fundamentals remain quite positive.  

CASH
The U.S. dollar was strong versus most currencies, including the yen, the German
mark, and the British pound, during the semi-annual period.  Strong domestic
economic growth, controlled inflation, and the Federal Reserve Board on hold,
along with high volatility in Asia and Latin America, added to the relative
attractiveness of the U.S. currency.  

INVESTMENT REVIEW
The Fund outperformed both the Asset Allocation Index-Long Range benchmark and
its Lipper category average. This strong relative performance was due primarily
to superior asset allocation.

Supported by the "new paradigm" of strong real growth and low inflation, as well
as by strong stock market momentum, low long-term interest rates, and a
relatively modest term premium, the Fund remained overweighted in U.S. stocks
for the semi-annual period.  As U.S. equities were the leading market for the
six months, such an allocation was the primary reason for the Fund's strong
performance.  Even though this sector did not match S&P performance, the Fund's
portfolio remained a top quartile performer, and individual security selection
remained strong. 

An underweight position in the U.S. bond market was supported by weak momentum
and increases in commodity prices, which, in turn, suggests inflationary
pressures.  The Fund's U.S. bond portfolio beat the Salomon Broad Investment
Grade (BIG) Index in the second calendar quarter and lagged it in the third
calendar quarter, to end the six months even versus the benchmark.  Corporate
and mortgage issue selection accounted for both the relative out- and
underperformance. 

The Fund's underweight position in U.S. bonds was used to fund a neutral
position in the international bond markets.  International stock and bond market
exposure provided diversification of risk, but did not make a substantial
contribution to return during this period, although light investment in
international equity markets, most consistently in Germany, helped performance. 
International bond market focus continued to be in Canada, France, and Japan*.

As of September 30, 1997, the Fund's asset weightings were 65% in U.S. equities,
20% in U.S. bonds, 10% in international bonds, 5% in international equities, and
0% in cash.

MANAGER OUTLOOK
Strong underlying fundamentals in the consumer sector, continued capital
investment, and increased government spending are all expected to keep the U.S.
economy on a relatively upward course, at least into the new year.  At some
point, we still anticipate that this relatively fast pace of economic growth
will generate some inflationary pressures.  Rising wage rates in response to the
tight labor market conditions are bound to put some pressure on profit margins,
force prices higher, or both.  As inflation picks up, interest rates are
expected to follow, although not to the degree feared earlier.

For the near term, then, the Fund remains overweight in U.S. stocks and
underweight in U.S. bonds.  We believe that a continual slowing of corporate
profits growth, as the economy slows and as margins are crimped, heighten the
possibility of correction in equity prices, as do the high current valuations. 
Any correction, though, is anticipated to be brief and mild, followed by renewed
strength.  As for the U.S. bond market, we believe a cautious stance is still
warranted for now, although the long-term fundamentals for bonds are still
favorable.

We believe Continental European markets continue to offer the best prospects
both for international equities and bonds.  In equities, France and the
periphery nations should benefit the most, as European unification will reward
companies that have taken the crucial steps required to be successful in the
increasingly competitive marketplace.  With Japanese bonds at record low levels
and convergence being fully discounted in all but the shortest of maturities
across peripheral Europe, we believe the largest potential for gains in the
coming months appear to be in the intermediate sector of core European markets
such as Germany.  

We will, of course, continue to closely observe economic conditions and how they
affect the financial markets, as we seek to provide high total return with
reduced risk over the long term.

We value your ongoing support of the BT Institutional Asset Management Fund and
look forward to continuing to serve your investment needs in the years ahead.

BT INSTITUTIONAL ASSET MANAGEMENT FUND

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

NOTE 1--ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
A. ORGANIZATION
BT Pyramid Mutual Funds (the "Trust") is registered under the Investment 
Company Act of 1940 (the "Act"), as amended, as an open-end management 
investment company. The Trust was organized on February 28, 1992, as a 
business trust under the laws of the Commonwealth of Massachusetts. The BT 
Institutional Asset Management Fund (the "Fund") is one of the funds offered 
to investors by the Trust. The Fund commenced operations and began offering 
shares of beneficial interest on September 16, 1993. The Fund invests 
substantially all of its assets in the Asset Management Portfolio (the 
"Portfolio"). The Portfolio is an open-end management investment company 
registered under the Act. The Fund seeks to achieve its investment objective 
by investing all of its investable assets in the Portfolio. The value of such 
investment in the Portfolio reflects the Fund's proportionate interest in the 
net assets of the Portfolio. At September 30, 1997, the Fund's investment was 
77% of the Portfolio.

The financial statements of the Portfolio, including the Schedule of Portfolio
Investments, are contained elsewhere in this report.

B. INVESTMENT INCOME
The Fund earns income, net of expenses, daily on its investment in the
Portfolio. All of the net investment income and realized and unrealized gains
and losses from the security transactions of the Portfolio are allocated pro
rata among the investors in the Portfolio at the time of such determination.

C. DIVIDENDS
It is the Fund's policy to declare and distribute dividends quarterly to
shareholders from net investment income. Dividends payable to shareholders are
recorded by the Fund on the ex-dividend date, which is the same as the
declaration date. Distributions of net realized short-term and long-term capital
gains, if any, will be made annually to the extent they are not offset by any
capital loss carryforwards.

D. FEDERAL INCOME TAXES
It is the Fund's policy to comply with the requirements of the Internal Revenue
Code applicable to regulated investment companies and distribute substantially
all of its taxable income to shareholders. Therefore, no federal income tax
provision is required.

E. OTHER
The Trust accounts separately for the assets, liabilities and operations of the
Fund. Expenses directly attributable to the Fund are charged to that Fund, while
expenses which are attributable to all of the Trust's funds are allocated among
them.

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts in the financial statements.

NOTE 2--FEES AND TRANSACTIONS WITH AFFILIATES
The Fund has entered into an Administration and Services Agreement with Bankers
Trust Company ("Bankers Trust"). Under this Administration and Services
Agreement, Bankers Trust provides administrative, custody, transfer agency and
shareholder services to the Fund in return for a fee computed daily and paid
monthly at an annual rate of 0.15 of 1% of the Fund's average daily net assets.
For the six months ended September 30, 1997, this fee aggregated $238,460.

Under the Distribution Agreement with the Trust, pursuant to Rule 12b-1 of the
Act, Edgewood may seek reimbursement, at an annual rate not exceeding 0.20 of 1%
of the Fund's average daily net assets, for expenses incurred in connection with
any activities primarily intended to result in the sale of the Fund's shares.
For the six months ended September 30, 1997, there were no reimbursable expenses
incurred under this agreement.

Bankers Trust has voluntarily undertaken to waive and reimburse expenses of the
Fund, to the extent necessary, to limit all expenses to 0.00 of 1% of the
average daily net assets of the Fund, excluding expenses of the Portfolio and
0.60 of 1% of the average daily net assets of the Fund, including expenses of
the Portfolio. For the six months ended September 30, 1997, expenses of the Fund
have been reduced by $269,947.

Certain trustees and officers of the Fund are also directors, officers and/or
employees of Edgewood. None of the trustees so affiliated received compensation
for services as trustees of the Fund. Similarly, none of the Fund's officers
received compensation from the Fund.

NOTE 3--SHARES OF BENEFICIAL INTEREST
At September 30, 1997, there were an unlimited number of shares of beneficial
interest authorized. Transactions in shares of beneficial interest were as
follows:

ASSET MANAGEMENT PORTFOLIO

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------

NOTE--1 ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
A. ORGANIZATION
The Asset Management Portfolio (the "Portfolio") is registered under the
Investment Company Act of 1940 (the "Act"), as amended, as an open-end
management investment company. The Portfolio was organized on June 9, 1992 as an
unincorporated trust under the laws of New York and commenced operations on
September 16, 1993. The Declaration of Trust permits the Board of Trustees (the
"Trustees") to issue beneficial interests in the Portfolio.

B. SECURITY VALUATION
The Portfolio's investments listed or traded on National Stock Exchanges or 
other domestic or foreign exchanges are valued based on the closing price of 
a security traded on that exchange prior to the time when the Portfolio 
assets are valued. Short-term obligations with remaining maturities of 60 
days or less are valued at amortized cost. Other short-term debt securities 
are valued on a mark-to-market basis until such time as they reach a 
remaining maturity of 60 days, whereupon they will be valued at amortized 
cost using their value on the 61st day. All other securities and other assets 
are valued at their fair value as determined in good faith under procedures 
established by and under the general supervision of the Trustees.

C. SECURITY TRANSACTIONS AND INVESTMENT INCOME
Security transactions are accounted for on a trade date basis. Dividend income,
less foreign taxes withheld, if any, is recorded on the ex-dividend date or upon
receipt of ex-dividend notification in the case of certain foreign securities.
Interest income is recorded on the accrual basis and includes amortization of
premium and accretion of discount on investments. Realized gains and losses from
securities transactions are recorded on the identified cost basis.

All of the net investment income and realized and unrealized gains and losses
from the security and foreign currency transactions of the Portfolio are
allocated pro rata among the investors in the Portfolio at the time of such
determination.

D. REPURCHASE AGREEMENTS
The Portfolio may enter into repurchase agreements with financial institutions
deemed to be creditworthy by the Portfolio's Investment Advisers, subject to the
seller's agreement to repurchase such securities at a mutually agreed upon
price. Securities purchased subject to repurchase agreements are deposited with
the Portfolio's custodian, and, pursuant to the terms of the repurchase
agreement, must have an aggregate market value greater than or equal to the
repurchase price plus accrued interest at all times. If the value of the
underlying securities falls below the value of the repurchase price plus accrued
interest, the Portfolio will require the seller to deposit additional collateral
by the next business day. If the request for additional collateral is not met,
or the seller defaults on its repurchase obligation, the Portfolio maintains the
right to sell the underlying securities at market value and may claim any
resulting loss against the seller. However, in the event of default or
bankruptcy by the seller, realization and/or retention of the collateral may be
subject to legal proceedings.

E. FOREIGN CURRENCY TRANSACTIONS
The books and records of the Asset Management Portfolio are maintained in U.S.
dollars. All assets and liabilities initially expressed in foreign currencies
are converted into U.S. dollars at prevailing exchange rates. Purchases and
sales of investment securities, dividend and interest income and certain
expenses are translated at the rates of exchange prevailing on the respective
dates of such transactions.

F. FORWARD FOREIGN CURRENCY CONTRACTS
The Portfolio may enter into forward foreign currency contracts for the purpose
of settling specific purchases or sales of securities denominated in a foreign
currency or with respect to the Portfolio's investments. The net U.S. dollar
value of foreign currency underlying all contractual commitments held by the
Portfolio and the resulting unrealized appreciation or depreciation are
determined using prevailing exchange rates. With respect to forward foreign
currency contracts, losses in excess of amounts recognized in the Statement of
Assets and Liabilities may arise due to changes in the value of the foreign
currency or if the counterparty does not perform under the contract.

G. OPTION CONTRACTS
The Portfolio may enter into option contracts. Upon the purchase of a put option
or a call option by the Portfolio, the premium paid is recorded as an
investment, valued at mark-to-market daily to reflect the current market value.
When a purchased option expires, the Portfolio will realize a loss in the amount
of the cost of the option. When the Portfolio enters into a closing sale
transaction, the Portfolio will realize a gain or loss depending on whether the
sale proceeds from the closing sale transaction are greater or less than the
cost of the option. When the Portfolio exercises a put option, it realizes a
gain or loss from the sale of the underlying security and the proceeds from such
sale will be decreased by the premium originally paid. When the Portfolio
exercises a call option, the cost of the security which the Portfolio purchases
upon exercise will be increased by the premium originally paid.

H. FUTURES CONTRACTS
The Portfolio may enter into financial futures contracts which are contracts to
buy a standard quantity of securities at a specified price on a future date. The
Portfolio is required to deposit either in cash or securities an amount equal to
a certain percentage of the contract amount. Subsequent payments are made or
received by the Portfolio each day, dependent on the daily fluctuations in the
value of the underlying security, and are recorded for financial statement
purposes as unrealized gains or losses by the Portfolio.

Futures contracts are valued at the settlement price established each day by the
board of trade or exchange on which they are traded.

I. FEDERAL INCOME TAXES
It is the Portfolio's policy to comply with the requirements of the Internal
Revenue Code. Therefore, no federal income tax provision is required.

J. OTHER
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts in the financial statements.

NOTE 2--FEES AND TRANSACTIONS WITH AFFILIATES
The Portfolio has entered into an Administration and Services Agreement with
Bankers Trust Company ("Bankers Trust"). Under this Administration and Services
Agreement, Bankers Trust provides administrative, custody, transfer agency and
shareholder services to
