BT PreservationPlus Fund

Letter to Shareholders
- --------------------------------------------------------------------------------


We are pleased to present you with this annual report for the year ended
September 30, 1999 for the BT PreservationPlus Fund (the "Fund"). It provides a
review of the market, the Portfolio, and our outlook. Included are a complete
financial summary of the Fund's operations and a listing of the Portfolio's
holdings.

The BT PreservationPlus Fund is the first SEC registered mutual fund
specifically designed as an investment alternative to traditional GIC commingled
funds and other stable value products. The Fund is open to investors in
participant-directed employee benefit plans that meet certain eligibility
criteria, including corporate 401(k), public 457, and not-for-profit 403(b)
plans.

MARKET ACTIVITY
Overall, the U.S. bond market was dominated by a dramatic increase in interest
rates during the twelve months ended September 30, 1999.

A myriad of political and economic events boosted the "spread sectors" but
lofted the U.S. yield curve across all maturities over the first six months of
the Fund's fiscal year, dragging down the performance of U.S. Treasury
securities.
o  The birth of the Euro currency, Brazilian devaluation, NATO military action
   in the Balkans, and heavy merger activity and booming debt origination in the
   U.S., were just some of the factors that led to disappointing returns from
   U.S. Treasuries. The Treasury market conceded to reduced concerns over
   international turmoil and increased investor demand for the higher yields
   offered by other fixed income sectors.
o  In contrast, the corporate, mortgage and asset-backed sectors rallied, as
   yield spreads tightened substantially with the return of liquidity to the
   fixed income markets. The mortgage and corporate bond sectors reacted
   favorably to three Federal Reserve Board easings, interest rate cuts in a
   number of other countries, and better coordination of international monetary
   policy. All three of the credit-dependent "spread sectors"--i.e. corporate,
   mortgage, and asset-backed--flourished with declining implied volatilities,
   subsiding refinancing worries, and a continuing reduction of liquidity
   premiums.

During the second half of the Fund's fiscal year, virtually all of the U.S.
fixed income sectors were impacted by higher interest rates, renewed inflation
fears, and a reversal in Federal Reserve Board policy.
o  To guard against the perceived risks of inflationary pressures brought on by
   an improving global economy, a still strong U.S. economy, and an extremely
   tight labor market, the Federal Reserve Board acted twice during the second
   half of the Fund's fiscal year. The Fed raised the fed funds rate by 0.25%
   each on June 30 and August 24. We believe the hike in rates marked a movement
   from the low growth/low yield environment of 1998 to the medium growth/medium
   yield arena of 1999.
o  U.S. Treasury yields continued to move sharply higher. For example, the
   5-year U.S. Treasury note rose 0.88% in the first half of the fiscal year and
   increased another 0.66% in the second half.
o  The "spread sectors" were impacted to an even greater degree, underperforming
   U.S. Treasuries for the six months ended September 30, 1999. During the
   second calendar quarter, yields on these sectors moved higher across all
   maturities, as yield spreads came under pressure from increased new issue
   offerings and concerns over prepayment volatility in the mortgage market.
   During the third calendar quarter, yield spreads on corporate bonds widened,
   as investors' concerns grew over the credit implications of increased
   inflation and its effect on earnings, while yield spreads on asset-backed
   securities tightened in September, as the new issue calendar failed to meet
   earlier volume expectations. Mortgage securities' yields rose dramatically in
   September, primarily due to higher interest rates and slower prepayments.

INVESTMENT REVIEW
Despite significant market volatility, the Fund met its objective of maintaining
a stable value per share and produced a high level of current income. The Fund's
NAV has remained steady at $10 per share every day since inception./1

The Portfolio is diversified across the major sectors of the investment grade
fixed income market. As of September 30, 1999, the Portfolio is allocated 41% to
corporate bonds, 25% to mortgage-backed securities, 2% to foreign bonds, 10% to
U.S. Treasuries/agencies, and 22% to cash equivalents. This allocation of fixed
income securities is intentionally weighted towards the corporate, asset-backed
and mortgage sectors, as these sectors have historically offered higher yields
than U.S. government securities. Additionally, the Fund has entered into Wrapper
Agreements that are intended to stabilize the Fund's NAV.

The Fund is the first SEC registered mutual fund to make use of Wrapper
Agreements to seek to maintain principal stability in the face of fluctuations
in values due to changes in yields. To date, we have negotiated four Wrapper
Agreements, each of which covers approximately one quarter of the fixed income
securities in the Portfolio covered by such Agreements. Generally speaking,
Wrapper Agreements are issued by insurance companies, banks and other financial
institutions. The Wrapper Agreements held by the Portfolio as of September 30,
1999 are issued by Bank of America NT&SA, National Westminster Bank PLC, Credit
Suisse Financial Products, and Transamerica Life Insurance & Annuity Co. This
continues to be a successful strategy for the Fund.

1/ Performance quoted represents past performance. The Fund seeks to maintain a
   constant $10.00 per share net asset value. The Fund is not a money market
   fund, and there can be no assurance that it will be able to maintain a stable
   share value. The Fund holds fixed income securities, money market
   instruments, futures, options, and other instruments, and contracts with
   financial institutions, such as insurance companies and banks that are
   intended to stabilize the value per share. The Fund is not insured by the
   FDIC and is not a deposit, obligation of, or guaranteed by Bankers Trust
   Company. The Fund is subject to investment risks, including possible loss of
   principal amount invested.
2/ In addition to the IBC Money Fund Averages, we use two alternative
   benchmarks. The Lehman 1 to 3 Year Government/Corporate Index, our primary
   benchmark, is a total return index consisting of all U.S. Government agency
   securities, U.S. Government Treasury securities, and all investment grade
   corporate debt securities with maturities of one to three years. We also have
   changed our second benchmark from the Ryan Labs 5 Year GIC Index, comparing
   our performance instead to the Wrapped Lehman Intermediate Index. This index
   more closely reflects the market sectors in which the Fund invests. Indices
   are unmanaged and investments cannot be made in an index.
3/ The benchmarks for the Since Inception time periods are calculated from
   September 30, 1997 for the Investment Class, from December 31, 1997 for the
   Institutional Class, from March 31, 1998 for the Institutional Service Class,
   and from September 30, 1998 for the Service Class comparisons.

The Fund has maintained a high quality portfolio. The average credit quality of
investments in the Fund improved during the year from AA+ at March 31 to AAA at
the end of the fiscal year, as measured by Standard & Poor's. The average
quality of the issuers of the Wrapper Agreements at that time was AA-, as
measured by Standard & Poor's. The Fund's duration at September 30, 1999 stood
at 3.16 years.

MANAGER OUTLOOK
Economic momentum continues to build around the world. U.S. growth has shown
little sign of slowing; the expansions in Europe have picked up speed; and the
recoveries in Asia have been surprisingly vigorous. We expect such global growth
trends to intensify and accelerate in a self-reinforcing manner over the balance
of 1999 and into 2000. This brighter world economic picture should continue to
fuel the sale of U.S. Treasuries by foreign investors. At the same time, we
believe that shifts by foreign investors to comparatively riskier asset classes
should provide a lift to the corporate, mortgage, and asset-backed spread
sectors.

We do not believe that this rebound in growth is likely to result in any serious
build up of inflationary pressures in Europe and Asia because of the ample
economic slack that still exists in those regions. In the U.S., by contrast,
while inflation remains low currently, recent hikes in the prices of oil and
gold, together with other indications of persistent economic strength, suggest
that inflation may increase at some point in the near future. Furthermore, labor
markets remain drum tight, so the risks of economic overheating are more
palpable unless growth cools down fairly soon. We continue to doubt that such a
slowing is in the cards for the near term given the U.S. economy's strong
fundamentals. This, along with the Federal Reserve Board's "tightening bias"
stance declared on October 5, leads us to expect some additional Fed tightening
and gradually building inflationary pressures to impart a cautious tone in U.S.
financial markets.

Given this outlook, we anticipate fixed income yields to drift a bit higher and
yield spreads to widen over the near term, as Y2K and liquidity concerns arise.
These conditions should present us with attractive, but limited, opportunities
to invest new cash flows at higher yield spreads. Over the longer term, we
maintain a generally positive but cautious outlook for the U.S. fixed income
markets.

We will maintain our long-term perspective for the Fund, monitoring economic
conditions and how they affect the financial markets, as we seek to provide a
high level of current income while seeking to maintain a stable value per share.
Our strategy is to continue to focus on selecting the highest quality spread
sector assets at the maximum yield possible, while normally maintaining a 10%
cash allocation to provide liquidity. This liquidity facilitates effective
wrapper agreement management while maximizing the return volatility of the fixed
income securities.

We value your support of the PreservationPlus Fund and look forward to serving
your investment needs in the years ahead.

BT PreservationPlus Fund

Notes to Financial Statements
- --------------------------------------------------------------------------------

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 PreservationPlus Fund (the
"Fund") is one of the funds offered to investors by the Trust.

The Fund offers four classes of shares to investors; Investment Class,
Institutional Class, Service Class and Institutional Service Class (the
"Classes"). All classes of shares have identical rights to earnings, assets and
voting privileges, except that each class has its own expenses and exclusive
voting rights with respect to matters affecting it.

The Investment, Institutional, Institutional Service, and Service Classes began
operations on October 1, 1997, December 14, 1997, April 1, 1998 and September
23, 1998, respectively.

The Fund seeks to achieve its investment objective by investing all of its
investable assets in the BT PreservationPlus Portfolio (the "Portfolio"). The
Portfolio is an open-end management investment company registered under the Act.
The value of such investment in the Portfolio reflects the Fund's proportionate
interest in the net assets of the Portfolio. At September 30, 1999, the Fund's
investment was approximately 100% of the Portfolio.

The financial statements of the Portfolio, including the Schedule of Portfolio
Investments, are contained elsewhere in this report and should be read in
conjunction with the Fund's financial statements.

B. Security Transactions and Related Investment Income
The Fund earns income, net of expenses, on its investment in the Portfolio. All
of the net investment income and net realized and unrealized gains and losses
(including Wrapper Agreements) of the Portfolio are allocated pro rata among the
investors in the Portfolio on a daily basis.

Security transactions are accounted for on the trade date. Realized gains and
losses on investments sold are computed on the basis of identified cost. The
realized and unrealized gains and losses in the Statement of Operations
represent the Fund's pro-rata interest in the realized and unrealized gains and
losses of the Portfolio, including the offsetting valuation change of the
Wrapper Agreements.

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

D. Federal Income Taxes
It is the Fund's policy to comply with the requirements of the Internal Revenue
Code and distribute income to shareholders. Therefore, no federal income tax
provision is required. The Fund may periodically make reclassifications among
certain of its capital accounts as a result of differences in the
characterization and allocation of certain income and capital gains determined
in accordance with federal tax regulations which may differ from generally
accepted accounting principles.

E. Other
The Trust accounts separately for the assets, liabilities and operations of each
fund and each class. Expenses directly attributable to a fund or class are
charged to that fund or class, while expenses which are attributable to all of
the Trust's funds or classes are allocated among them on the basis of relative
net assets.

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. Actual results could
differ from those estimates.

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 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 .25% of
average daily net assets for the Investment and Service classes and .10% of
average daily net assets for the Institutional and Institutional Service
classes.

The Service and Institutional Service Classes are also subject to shareholder
servicing fees in the maximum amount of .25% and .15% of average daily net
assets, respectively.

ICC Distributors, Inc. provides distribution services to the Fund.

Bankers Trust has voluntarily undertaken to waive its fees and reimburse
expenses of each Class, to the extent necessary to limit all expenses as
follows: Investment Class of Shares to .20% of the average daily net assets of
the Class, excluding expenses of the Portfolio and .55% of the average daily net
assets of the Class, including expenses of the Portfolio; Service Class of
Shares to .45% of the average daily net assets of the Class, excluding expenses
of the Portfolio and .80% of the average daily net assets of the Class,
including expenses of the Portfolio; Institutional Class of Shares to .05% of
the average daily net assets of the Class, excluding expenses of the Portfolio
and .40% of the average daily net assets of the Class, including expenses of the
Portfolio; and Institutional Service Class to .20% of the average daily net
assets of the Class, excluding expenses of the Portfolio and .55% of the average
daily net assets of the Class, including expenses of the Portfolio.

Shareholder transaction expenses are charges paid when investors buy, redeem or
exchange Shares. Under normal circumstances, redemptions of Shares that are
directed by Plan participants are not subject to a redemption fee. Redemptions
of Shares that are not directed by Plan participants and that are made on less
than twelve months' prior written notice to the Fund are subject to a redemption
fee payable to the Fund of 2% of the proceeds of the redemption.

Bankers Trust was a wholly owned subsidiary of Bankers Trust Corporation ("BT
Corp."). On June 4, 1999, BT Corp. was acquired by Deutsche Bank AG ("Deutsche
Bank"). As a result of the transaction, Bankers Trust became an indirect
wholly-owned subsidiary of Deutsche Bank.

Note 3--Shares of Beneficial Interest
At September 30, 1999, there were an unlimited number of shares of beneficial
interest authorized. Transactions in shares of beneficial interest were as

Note 4--Additional Distributions
In order to comply with requirements of the Internal Revenue Code applicable to
regulated investment companies, the Fund is required to distribute accumulated
net realized gains, if any, on an annual basis. When such distributions are
made, the immediate impact is a corresponding reduction in the net asset value
per share of each Class. Given the objective of the Fund to maintain a stable
net asset value of $10 per share, the Fund intends to declare a reverse stock
split immediately subsequent to any such distributions at a rate that will cause
the total number of shares held by each shareholder, including shares acquired
on reinvestment of that distribution, to remain the same as before the
distribution was paid and in effect reinstate a net asset value of $10 per
share.

On December 4, 1998, the Fund declared a capital gain distribution of $.05 per
share and a corresponding reverse stock split of .995 per share. There was no
effect on the value of the total holdings of each shareholder (assuming
reinvestment of such distributions) as a result of this
activity.

Report of Independent Auditors
- --------------------------------------------------------------------------------

To the Shareholders and Board of Trustees
BT Pyramid Mutual Funds - BT PreservationPlus Fund

We have audited the accompanying statement of assets and liabilities of BT
PreservationPlus Fund (the "Fund") as of September 30, 1999, and the related
statement of operations for the year then ended, the statements of changes in
net assets for each of the two years in the period then ended, and the financial
highlights for each of the periods indicated therein. These financial statements
and financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of BT
PreservationPlus Fund at September 30, 1999, the results of its operations for
the year then ended, the changes in its net assets for each of the two years in
the period then ended, and its financial highlights for each of the periods
indicated therein, in conformity with generally accepted accounting principles.

BT PreservationPlus Portfolio

Notes to Financial Statements
- --------------------------------------------------------------------------------

Note 1--Organization and Significant Accounting Policies
A. Organization
The BT PreservationPlus 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 and began operations
on October 1, 1997 as an unincorporated trust under the laws of New York. The
Declaration of Trust permits the Board of Trustees (the "Trustees") to issue
beneficial interests in the Portfolio.

B. Security Valuation
Debt securities (other than short-term debt obligations maturing in 60 days or
less), including listed securities and securities for which price quotations are
available, will normally be valued on the basis of market valuations furnished
by a pricing service. Such market valuations may represent the last quoted price
on the securities' major trading exchange or quotes received from dealers or
market makers in the relevant securities or may be determined through the use of
matrix pricing. In matrix pricing, pricing services may use various pricing
models involving comparable securities, historic relative price movements,
economic factors and dealer quotations. Over-the-counter securities are normally
valued at the bid price. Short-term debt obligations and money market securities
maturing in 60 days or less are valued at amortized cost. Securities for which
market quotations are not readily available are valued by Bankers Trust pursuant
to procedures adopted by the Portfolio's Board of Trustees.

Wrapper Agreements generally will be equal to the difference between the Book
Value and Market Value (plus the crediting rate adjustment) on the applicable
covered assets and will either be reflected as an asset or liability of the
Portfolio. The Portfolio's Board of Trustees, in performing its fair value
determination of the Portfolio's Wrapper Agreements, considers the
creditworthiness and the ability of Wrapper Providers to pay amounts due under
the Wrapper Agreements.

C. Security Transactions and Interest Income
Security transactions are accounted for on a trade date basis. Interest income
is recorded on an accrual basis and includes amortization of premium and
discount on investments. Realized gains and losses from security transactions
are recorded on an identified cost basis. The credited rate interest represents
the actual interest earned on covered assets under the Portfolio's Wrapper
Agreements plus or minus an adjustment for an amount receivable from or payable
to the wrapper provider based on fluctuation in the market value of covered
assets.

All of the net investment income and net realized and unrealized gains and
losses (including the Wrapper Agreements) of the Portfolio are allocated pro
rata to the investors in the Portfolio on a daily basis.

D. TBA Purchase Commitments
The Portfolio may enter into "TBA" (to be announced) purchase commitments to
purchase securities for a fixed price at a future date, typically not exceeding
45 days. TBA purchase commitments may be considered securities in themselves,
and involve a risk of loss if the value of the security to be purchased declines
prior to settlement date. Unsettled TBA purchase commitments are valued at the
current market value of the underlying securities, according to the procedures
described under "Security Valuation" above.

E. Federal Income Taxes
The Portfolio is considered a partnership under the Internal Revenue Code.
Therefore, no federal income tax provision is necessary.

F. 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. Actual results could
differ from those estimates.

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 agreement, Bankers Trust
provides administrative, custody, transfer agency and shareholder services to
the Portfolio in return for a fee computed daily and paid monthly at an annual
rate of .05% of the Portfolio's average daily net assets.

The Portfolio has entered into an Advisory Agreement with Bankers Trust. Under
this agreement, the Portfolio pays Bankers Trust an advisory fee computed daily
and paid monthly at an annual rate of .35% of the Portfolio's average daily net
assets, less advisor fees paid for the pro rata amount due to investment in the
Institutional Cash Management Fund.

Bankers Trust has voluntarily undertaken to waive its fees and reimburse
expenses of the Portfolio, to the extent necessary, to limit all expenses to
 .35% of the average daily net assets of the Portfolio.

The Portfolio may invest in the Institutional Cash Management Fund (the "Fund"),
an open-end management investment company managed by Bankers Trust. The Fund is
offered as a cash management option to the Portfolio and other accounts managed
by Bankers Trust. Distributions from the Fund to the Portfolio for the year
ended September 30, 1999 amounted to $2,951,834.

At September 30, 1999, the Portfolio was a participant with other affiliated
entities in a revolving credit facility in the amount of $100,000,000, which
expires April 29, 2000. A commitment fee of .10% per annum on the average daily

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


amount of the available commitment is payable on a quarterly basis and
apportioned equally among all participants. On October 8, 1999, the revolving
credit facility was increased to $150,000,000. No amounts were outstanding under
the credit facility for the year ended September 30, 1999.

Bankers Trust was a wholly owned subsidiary of Bankers Trust Corporation ("BT
Corp."). On June 4, 1999, BT Corp. was acquired by Deutsche Bank AG ("Deutsche
Bank"). As a result of the transaction, Bankers Trust became an indirect
wholly-owned subsidiary of Deutsche Bank.

Note 3--Purchases and Sales of Investment Securities
The aggregate cost of purchases and proceeds from sales of investments, other
than short-term obligations, for the year ended September 30, 1999, were
$845,562,428 and $744,984,453, respectively. For federal income tax purposes,
the tax basis of investments held at September 30, 1999, was $394,943,913. The
aggregate gross unrealized appreciation was $463,318, and the aggregate gross
unrealized depreciation for all investments was $7,614,231 as of September 30,
1999.

Note 4--Wrapper Agreements
The Portfolio will enter into Wrapper Agreements with insurance companies, banks
or other financial institutions ("Wrapper Providers") that are rated, at the
time of purchase, in one of the top two long-term rating categories by Moody's
or S&P. A wrapper agreement is a derivative instrument that is designed to
protect the portfolio from investment losses and under most circumstances permit
the Fund to maintain a constant NAV per share. There is no active trading market
for Wrapper Agreements, and none is expected to develop; therefore, they are
considered illiquid.

A default by the issuer of a Portfolio Security or a Wrapper Provider on its
obligations might result in a decrease in the value of the Portfolio assets. The
Wrapper Agreements generally do not protect the Portfolio from loss if an issuer
of Portfolio Securities defaults on payments of interest or principal.
Additionally, a Fund shareholder may realize more or less than the actual
investment return on the Portfolio Securities depending upon the timing of the
shareholder's purchases and redemption of Shares, as well as those of other
shareholders.

Report of Independent Auditors
- --------------------------------------------------------------------------------

To the Shareholders and Board of Trustees
BT PreservationPlus Portfolio

We have audited the accompanying statement of assets and liabilities, including
the schedule of portfolio investments, of BT PreservationPlus Portfolio (the
"Portfolio") as of September 30, 1999, the related statement of operations for
the year then ended and the statements of changes in net assets and the
financial highlights for each of two years in period then ended. These financial
statements and financial highlights are the responsibility of the Portfolio's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights. Our procedures included confirmation of
securities owned as of September 30, 1999, by correspondence with the
Portfolio's custodian and brokers. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly in all material respects, the financial position of BT
PreservationPlus Portfolio at September 30, 1999, the results of its operations
for the year then ended, and the changes in its net assets and its financial
highlights for each of the two years in the period then ended, in conformity
with generally accepted accounting principles.
