Dear ProFund Shareholders,

It is with great pleasure that we present to you the first Annual Report to 
Shareholders, of the ProFunds.

We are very gratified with the early progress of the ProFunds, In a little over 
one month since we commenced investment activities on November 26, 1997, assets 
of the ProFunds grew to $12,210,421 at December 31, 1997. Most importantly, 
while our start up period was marked by substantial volatility in the domestic 
and international markets, the ProFunds achieved high correlation to their 
benchmarks.

Thank you for your confidence in the ProFunds' management team during our 
introduction. In 1998 we look forward to continue providing you, our 
shareholders, with the investment tools and flexibility that allow you to pursue
your investment objectives.

If you have any questions feel free to call us at 888-776-3637.

Sincerely,

/s/ Michael L. Sapir

Michael L. Sapir
Chairman

ProFunds
Notes to Financial Statements
December 31, 1997



1)   Organization

ProFunds (the "Trust") is a registered open-end investment company under the
Investment Company Act of 1940 (the "1940 Act"). The Trust was organized as a
Delaware business trust on April 17, 1997, and has authorized capital of
unlimited shares of beneficial interest of no par value which may be issued in
more than one class or series. Currently, the Trust consists of six separately
managed series: Bull ProFund, UltraBull ProFund, Bear ProFund, UltraBear
ProFund, UltraOTC ProFund, and Money Market ProFund (individually, a "ProFund").
Each ProFund offers two classes of shares: the Service Shares and the Investor
Shares.

The investment objectives of the ProFunds are as follows:

The Bull ProFund and the UltraBull ProFund. The Bull ProFund's investment
objective is to provide investment returns that correspond to the performance of
the S&P 500 Index. The UltraBull ProFund's investment objective is to provide
investment returns that correspond to 200% of the performance of the S&P 500
Index. The UltraBull ProFund should gain more than the Bull ProFund when the
prices of the securities in the S&P 500 Index rise and lose more when such
prices decline.

The Bear ProFund and the UltraBear ProFund. The Bear ProFund's investment
objective is to provide investment results that will inversely correlate to the
performance of the S&P 500 Index. The UltraBear ProFund's investment objective
is to provide investment results that will inversely correlate to 200% of the
performance of the S&P 500 Index.

If the Bear ProFund is successful in meeting its objective, the net asset value
of Bear ProFund shares will increase in direct proportion to any decrease in the
level of the S&P 500 Index. Conversely, the net asset value of Bear ProFund
shares will decrease in direct proportion to any increases in the level of the
S&P 500 Index. The percentage change of net asset value of shares of the
UltraBear ProFund should increase or decrease approximately twice as much as
does that of the Bear ProFund on any given day.

The UltraOTC ProFund. The investment objective of the UltraOTC ProFund is to
provide investment results that correspond to 200% of the performance of the
NASDAQ 100 Index. The NASDAQ 100 Index includes 100 of the largest non-financial
domestic companies listed on the NASDAQ National Market tier of The NASDAQ Stock
Market.

The Money Market ProFund. The Money Market ProFund seeks, as its investment
objective, a high level of current income consistent with liquidity and
preservation of capital. To achieve its objective, the Money Market ProFund
invests all of its investable assets in the Cash Management Portfolio
("Portfolio"), which has the same investment objective as the Money Market
ProFund.

The performance of the Money Market ProFund is directly affected by the
performance of the Portfolio. The financial statements of the Portfolio,
including its schedule of investments, are included elsewhere within this report
and should be read in conjunction with the Money Market ProFund's financial
statements.

2)   Significant Accounting Policies

The following is a summary of significant accounting policies consistently
followed by each ProFund in preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles. The
preparation of financial statements in accordance with generally accepted
accounting 

                                       15

Notes to Financial Statements -- Continued


principles requires management to make estimates and assumptions that effect the
reported amount of assets and liabilities and disclosure of contingent assets
and liabilities at the date of the financial statements and the reported amounts
of income and expense during the reporting period. The actual results could
differ from those estimates.

a)   Investment Valuation

The securities, except as otherwise noted, in the portfolio of a non-money
market ProFund that are listed or traded on a stock exchange, are valued on the
basis of the last sale on that day or, lacking any sales, at a price that is the
mean between the closing bid and asked prices. Other securities that are traded
on the OTC markets are priced using NASDAQ, which provides information on bid
and asked prices quoted by major dealers in such stocks. Bonds, other than
convertible bonds, are valued using a third-party pricing system. Convertible
bonds are valued using this pricing system only on days when there is no sale
reported. Short-term debt securities are valued at amortized cost, which
approximates market value. When market quotations are not readily available,
securities and other assets are valued at fair value as determined in good faith
under procedures established by and under general supervision and responsibility
of the ProFund's Board of Trustees.

Puts, calls and futures contracts purchased and held by the ProFunds are valued
at the close of the securities or commodities exchanges on which they are
traded. Options on securities and indices purchased by a ProFund generally are
valued at their last bid price in the case of exchange-traded options or, in the
case of options traded in the OTC market, the average of the last bid price as
obtained from two or more dealers unless there is only one dealer, in which case
that dealer's price is used. Futures contracts are valued with reference to
established futures exchanges. The value of a futures contract purchased by the
ProFunds will be either the closing price of that contract or the bid price.
Conversely, the value of a futures contract sold by the ProFunds will be either
the closing price or the asked price. The value of options on futures contracts
is determined based upon the current settlement price for a like option acquired
on the day on which the option is being valued.

Valuation of securities held by the Portfolio is discussed in Note 1 of the
notes to financial statements of the Portfolio which are included elsewhere in
this report.

b)   Repurchase Agreements

Under a repurchase agreement, a ProFund purchases a debt security and
simultaneously agrees to sell the security back to the seller at a mutually
agreed-upon future price and date, normally one day or a few days later. The
resale price is greater than the purchase price, reflecting an agreed-upon
market interest rate during the purchaser's holding period. While the maturities
of the underlying securities in repurchase transactions may be more than one
year, the term of each repurchase agreement will always be less than one year. A
ProFund will enter into repurchase agreements only with member banks of the
Federal Reserve System or primary dealers of U.S. government securities. The
Advisor and, with respect to the Portfolio, Bankers Trust, will monitor the
creditworthiness of each of the firms which is a party to a repurchase agreement
with any of the ProFunds.

The ProFunds require that the securities purchased in a repurchase agreement
transaction be transferred to the custodian in a manner sufficient to enable the
ProFund to obtain those securities in the event of a counterparty default. The
seller, under the repurchase agreement, is required to maintain the value of the
securities held at not less than the repurchase price, including accrued
interest. Repurchase agreements are considered to be loans under the 1940 Act.

c)   Federal Income Tax

Each of the ProFunds intends to elect to be treated to qualify each year as a
regulated investment company (a "RIC") under Subchapter M of the Internal
Revenue Code of 1986, as amended. A RIC generally is not subject to federal
income tax on income and gains distributed in a timely manner to its
shareholders; the ProFunds intend to make timely distributions in order to avoid
tax liability.

d)   Securities Transactions and Related Income

Securities transactions are accounted for on the date the security is purchased
or sold (trade date). Interest income is recognized on the accrual basis and
includes, where applicable, the pro rata amortization of premium or discount.
Dividend income is recorded on the ex-dividend date. Gains or losses realized on
sales of securities are determined by comparing the identified cost of the
security lot sold with the net sales proceeds.

e)   Dividends, Distributions and Expenses

The ProFunds, other than the Money Market ProFund, will distribute net
investment income and net realized gains, if any, will be declared and
distributed at least once a year. Each ProFund bears expenses incurred
specifically on its behalf as well as a portion of general expenses.

The Money Market ProFund ordinarily (i) declares dividends of net investment
income (and net short-term capital gains, if any) for shares of the Money Market
ProFund on a daily basis and (ii) distributes such dividends to shareholders of
the Money Market ProFund on a monthly basis. Net realized capital gains will be
distributed annually.

All income dividends and capital gains distributions of each ProFund
automatically will be reinvested in additional shares of the ProFund at the net
asset value calculated on the ex-dividend date, unless an investor has requested
otherwise in writing.

f)   Capital Accounts

The Trust follows the provisions of the AICPA's Statement of Position 93-2
"Determination, Disclosure and Financial Statement Presentation of Income,
Capital Gain and Return of Capital Distributions by Investment Companies"
("SOP"). The purpose of this SOP is to report undistributed net investment
income and accumulated net realized gain or loss in such a manner as to
approximate amounts available for future distributions to shareholders, if any.

g)    Short Sales

When the Trust engages in a short sale, an amount equal to the proceeds received
by the Trust is reflected as an asset and an equivalent liability. The amount of
the liability is subsequently marked to market to reflect the market value of
the short sale. The Trust maintains a segregated account of securities as
collateral for the short sales. The Trust is exposed to market risk based on the
amount, if any, that the market value of the stock exceeds the market value of
the securities in the segregated account.

h)    Options

When the Trust writes (sells) an option, an amount equal to the premium received
is entered in the Trust's accounting records as an asset and equivalent
liability. The amount of the liability is subsequently marked to market to
reflect the current value of the option written. When an option expires, or if
the Trust enters into a closing purchase transaction, the Trust realizes a gain
(or loss if the cost of a closing purchase transaction exceeds the premium
received with the option was sold).

i)    Futures Contracts

The Trust may purchase or sell stock index futures contracts and options on such
futures contracts. Futures contracts are contracts for delayed delivery of
securities at a specified future delivery date and at a specific price. Upon
entering into a contract, the Trust deposits and maintains as collateral such
initial margin as required by the exchange on which the transaction is effected.
Pursuant to the contract, the Trust agrees to receive from or pay to the broker
an amount of cash equal to the daily fluctuation in value of the contract. Such
receipts or payments are known as variation margin and are recorded by the Trust
as unrealized gains or losses. When the contract is closed, the Trust records a
realized gain or loss 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.

j)    Risks of Futures Contracts and Options

Futures contracts and written options involve, to varying degrees, elements of
market risk and risks in excess of the amount recognized in the Statements of
Assets and Liabilities. The face or contract amounts reflect the extent of the
involvement each ProFund has in the particular classes of instruments. Risks may

                                       17

Notes to Financial Statements -- Continued


be caused by an imperfect correlation between movements in the price of the
instruments and the price of the underlying securities.

k)    Organization Costs

Costs incurred by the Trust in connection with its organization have been
deferred and are being amortized on the straight-line method over a five-year
period beginning on the date on which each ProFund commenced its investment
activities.

beneficial interest authorized. Transactions in shares of beneficial interest

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Trustees and Shareholders
of ProFunds

We have audited the accompanying statements of assets and liabilities of 
ProFunds (comprising, respectively, the Bull ProFund, UltraBull ProFund, Bear 
ProFund, UltraBear ProFund, UltraOTC ProFund, and Money Market ProFund), 
including the schedules of portfolio investments, as of December 31, 1997, and 
the related statements of operations, statements of changes in net assets, and 
the financial highlights for the period then ended. These financial statements 
and financial highlights are the responsibility of ProFunds 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 required 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. Our procedures included confirmation of securities owned as of 
December 31, 1997 by correspondence with the 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 
ProFunds as of December 31, 1997, and the results of their operations, the 
changes in their net assets and their financial highlights for the period then 
ended in conformity with generally accepted accounting principles.

Cash Management Portfolio

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

Note 1--Organization and Significant Accounting Policies

A.  Organization
The Cash 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 March 26, 1990, as
an unincorporated trust under the laws of New York, and commenced operations on
July 23, 1990. The Declaration of Trust permits the Board of Trustees (the
"Trustees") to issue beneficial interests in the Portfolio.

B.  Security Valuation
Investments are valued at amortized cost, which is in accordance to Rule 2a-7 of
the Investment Company Act of 1940 and represents the fair value of the
Portfolio's investments.

C.  Security Transactions and Interest Income
Security transactions are accounted for on a trade date basis. Interest income
is recorded on the accrual basis and includes amortization of premium and
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 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 Advisor, 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 all 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.  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.

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 Administration and Services
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 0.05 of 1% of the Portfolio's average daily
net assets. For the year ended December 31, 1997, this fee aggregated
$2,181,394.

The Portfolio has entered into an Advisory Agreement with Bankers Trust. Under
this Advisory Agreement, the Portfolio pays Bankers Trust an advisory fee
computed daily and paid monthly at an annual rate of 0.15 of 1% of the
Portfolio's average daily net assets. For the year ended December 31, 1997, this
fee aggregated $6,544,181.

Bankers Trust has voluntarily undertaken to waive its fees and reimburse
expenses of the Portfolio, to the extent necessary, to limit all expenses to
0.18 of 1% of the average daily net assets of the Portfolio. For the year ended
December 31, 1997, expenses of the Portfolio have been reduced by $940,530.

In 1994, the Portfolio sold certain structured notes carried at par to an
unrelated third party financial institution at par plus accrued interest to a
put agreement and that third party financial institution immediately resold such
security to Bankers Trust New York Corporation, the parent of the Advisor, at
the same price, also pursuant to a put agreement. As a result of these
transactions the Portfolio's Financial Highlights for the year ended December
31, 1994 reflects the Portfolio's realized loss on the sale of these securities
and a capital contribution in the amount of $18,718,663. In 1996, Bankers Trust
contributed capital in the amount of $1,113,488 to reimburse the Cash Management
Portfolio for capital losses incurred in prior years.

Certain trustees and officers of the Portfolio are also directors, officers
and/or employees of Edgewood Services, Inc., distributor of BT Institutional
Funds. None of the trustees so affiliated received compensation for services as
trustees of the Portfolio. Similary, none of the Portfolio's officers received 
compensation from the Portfolio.

Cash Management Portfolio

Report of Independent Accountants
- --------------------------------------------------------------------------------

To the Trustees and Holders of Beneficial Interest of the Cash
Management Portfolio:

We have audited the accompanying statement of assets and liabilities, including
the schedule of portfolio investments, of the Cash Management Portfolio as of
December 31, 1997, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended and the financial highlights for each of the five years in the
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. Our procedures included confirmation of securities owned as of
December 31, 1997, by correspondence with the 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 the
Cash Management Portfolio as of December 31, 1997, 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 the financial highlights for each of the five years
in the period then ended, in conformity with generally accepted accounting
principles.
