PRESIDENT'S MESSAGE
- --------------------------------------------------------------------------------

Dear Shareholder:

I am pleased to present the Annual Report to Shareholders for Government Cash
Series (the "Fund"), which covers the twelve-month period ended May 31, 1994.
The report includes the Investment Review and Financial Statements, which
contain the Portfolio of Investments.

Government Cash Series pursues current income--along with the additional
advantages of daily liquidity and stability of principal*--through some of the
most secure investments available. Because of their yield advantage, repurchase
agreements backed fully by short-term U.S. government securities accounted for
63.5% of the portfolio at the end of the reporting period.

At the end of the period, the Fund's net assets stood at $401.3 million.
Dividends paid to shareholders during the period totaled $10.7 million, or $0.02
per share.

Thank you for putting your cash to work through Government Cash Series. Please
contact your investment representative if you have any questions about the Fund.
We will continue to keep you up to date on your investment.

Sincerely,

Richard B. Fisher
President
July 15, 1994

* As a money market mutual fund, the Fund is managed to pursue a stable share
  price of $1.00, although there is no guarantee that it will do so.


INVESTMENT REVIEW
- --------------------------------------------------------------------------------

Government Cash Series (the "Fund") is invested in direct U.S. Treasury and U.S.
Government agency obligations and in repurchase agreements which have these
securities as collateral. Although the Fund has maintained a Treasury position
due to narrow agency yield spreads over Treasuries, the Fund continues to invest
in issues of the Federal National Mortgage Association, Student Loan Marketing
Association, Farm Credit Bank System, Federal Home Loan Bank System, and Federal
Home Loan Mortgage Corporation. Recently, the Fund has been managed with a
somewhat conservative average maturity of 30-40 days.

The reporting period brought the first changes in Federal Reserve (the "Fed")
policy since September, 1992. The Fed tightened monetary policy by increasing
the Federal Fund target rate from 3% to 4.25% over the period from February
through May. The moves were viewed as being a preemptive strike against the
threat of inflation by removing the stimulus that the Fed had been providing to
the economy through an overly accommodative policy stance. With inflation
apparently under control and economic growth slowing slightly, Fed policy
appears to be on hold temporarily at its current neutral stance. However, rising
capacity utilization rates, commodity prices, and other inflation measures may
prompt another tightening by the Fed sometime this summer in order to keep
inflation firmly in check.

Prior to the policy changes by the Fed, movements in short rates were largely
driven by market sentiment during the reporting period. The rate on the three
month Treasury bill fell from 3.1% at the end of May 1993 to 3.0% at the end of
September. The rate then rose to 3.2% by the end of November and then returned
to near 3% by the end of January. Once the Fed began tightening in February, the
three-month Treasury bill rate then rose steadily to 4.25% by the end of May,
1994.

As a yield advantage continued to exist for investments in repurchase agreements
versus direct investments in short-term Treasury and agency securities, a
substantial percentage of the Fund's investments remained in repurchase
agreements. The Fund continued to combine attractive yields from repurchase
agreements collateralized by U.S. government mortgage-backed securities with
short-term agency floating rate notes and Treasury and agency securities with
longer maturities of 6 to 12 months. We believe this portfolio structure
continues to provide a competitive yield.

Over the reporting period, the Fund's average maturity drifted shorter in the
face of the somewhat uncertain environment created by the Fed. In light of the
expectations of additional tightening in monetary policy, the Fund is expected
to continue to maintain its conservative posture in the near future, while
maximizing performance through ongoing relative value analysis. However,
changing economic and market developments are continuously monitored to best
serve our clients attracted to the short-term U.S. government market.

GOVERNMENT CASH SERIES
NOTES TO FINANCIAL STATEMENTS
MAY 31, 1994
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Cash Trust Series, Inc. (the "Corporation"), is registered under the Investment
Company Act of 1940, as amended (the "Act"), as an open-end management
investment company. The Corporation consists of four portfolios. The financial
statements included herein present only those of Government Cash Series (the
"Fund"). The financial statements of the other portfolios are presented
separately. The assets of each portfolio are segregated and a shareholder's
interest is limited to the portfolio in which shares are held.

Effective June 15, 1993, shareholders approved the reorganization of the fund as
a portfolio of Cash Trust Series, Inc., a Maryland corporation.

(2) SIGNIFICANT ACCOUNTING POLICIES

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

A. INVESTMENT VALUATIONS--The Fund's use of the amortized cost method to value
   its portfolio securities is in accordance with Rule 2a-7 under the Act.

B. REPURCHASE AGREEMENTS--It is the policy of the Fund to require the custodian
   bank to take possession, to have legally segregated in the Federal Reserve
   Book Entry System or to have segregated within the custodian bank's vault,
   all securities held as collateral in support of repurchase agreement
   investments. Additionally, procedures have been established by the Fund to
   monitor, on a daily basis, the market value of each repurchase agreement's
   underlying collateral to ensure the value at least equals the principal
   amount of the repurchase agreement, including accrued interest.

   The Fund will only enter into repurchase agreements with banks and other
   recognized financial institutions such as broker/dealers which are deemed by
   the Fund's adviser to be creditworthy pursuant to guidelines established by
   the Board of Directors ("Directors"). Risks may arise from the potential
   inability of counterparties to honor the terms of the repurchase agreement.
   Accordingly, the Fund could receive less than the repurchase price on the
   sale of collateral securities.

C. INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS--Interest income and expenses
   are accrued daily. Bond premium and discounts, if applicable, are amortized
   as required by the Internal Revenue Code, as amended (the "Code").
   Distributions to shareholders are recorded on the ex-dividend date.

D. FEDERAL TAXES--It is the Fund's policy to comply with the provisions of the
   Code applicable to regulated investment companies and to distribute to
   shareholders each year substantially all of its taxable income. Accordingly,
   no provisions for federal tax are necessary.


GOVERNMENT CASH SERIES
- --------------------------------------------------------------------------------

E. WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS--The Fund may engage in
   when-issued or delayed delivery transactions. A Fund records when-issued
   securities on the trade date and maintains security positions such that
   sufficient liquid assets will be available to make payment for the securities
   purchased. Securities purchased on a when-issued or delayed delivery basis
   are marked to market daily and begin earning interest on the settlement date.

F. DEFERRED EXPENSES--The costs incurred by the Fund with respect to
   registration of its shares in its first fiscal year, excluding the initial
   expense of registering the shares, have been deferred and are being amortized
   using the straight-line method over a period of five years from the Fund's
   commencement date.

G. OTHER--Investment transactions are accounted for on the trade date.

(3) CAPITAL STOCK

At May 31, 1994, there were 12,500,000,000 shares of $0.001 par value capital
stock authorized. Capital paid in aggregated $401,333,704. Transactions in
capital stock were as follows:

INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

To the Board of Directors of

CASH TRUST SERIES, INC. and

Shareholders of GOVERNMENT CASH SERIES:

We have audited the accompanying statement of assets and liabilities of
Government Cash Series (one of the portfolios comprising Cash Trust Series,
Inc.), including the portfolio of investments, as of May 31, 1994, the related
statement of operations for the year then ended, the statement of changes in net
assets for the years ended May 31, 1994 and 1993, and the financial highlights
for each of the years in the five-year period ended May 31, 1994. 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. Our procedures included confirmation of the securities owned as of
May 31, 1994 by correspondence with the custodian and brokers; where replies
were not received from brokers, we performed other auditing procedures. 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, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Government Cash
Series as of May 31, 1994, the results of its operations, the changes in its net
assets, and its financial highlights for the respective stated periods in
conformity with generally accepted accounting principles.

PRESIDENT'S MESSAGE
- --------------------------------------------------------------------------------

Dear Shareholder:

I am pleased to present the Annual Report to Shareholders for Municipal Cash
Series (the "Fund"), which covers the twelve-month period ended May 31, 1994.
The report includes the Investment Review and Financial Statements, which
contain the Portfolio of Investments.

Municipal Cash Series pursues current income exempt from federal regular income
tax*--along with the additional advantages of daily liquidity and stability of
principal**--through a portfolio of short-term municipal securities. At the end
of the period, the portfolio was invested in securities issued by municipalities
in 34 states.

At the end of the period, the Fund's net assets stood at $574.8 million, a
dramatic increase of more than $119 million over the assets at the beginning of
the period. Dividends paid to shareholders during the period totaled $9.9
million, or $0.02 per share.

Thank you for putting your cash to work pursuing tax-free income through
Municipal Cash Series. Please contact your investment representative if you have
any questions about the Fund. We will continue to keep you up to date on your
investment progress.

Sincerely,

Richard B. Fisher
President
July 15, 1994

 * Income may be subject to the federal alternative minimum tax.

** As a money market mutual fund, the Fund is managed to pursue a stable share
   price of $1.00, although there is no guarantee that it will do so.



INVESTMENT REVIEW
- --------------------------------------------------------------------------------

Municipal Cash Series (the "Fund"), invests in high quality, short-term
tax-exempt debt securities and seeks to maintain a constant net asset value of
$1.00 a share. For the twelve-month period ending May 31, 1994, the Fund paid
shareholders a net annualized return of 1.83%. This is equivalent to a taxable
money market fund return in the highest federal tax bracket of 39.6% of 2.96%.
Tax-exempt funds provide an attractive alternative to taxable money market
funds.

The first few months of the reporting period were characterized by slow economic
growth coupled with low inflationary pressures. With little threat of inflation,
the municipal markets responded with some of the lowest yields over the past
decade in both the bonds and the money market. Despite the low yield
environment, total assets of municipal money market funds reached an all-time
high of over $116 billion in March, 1994, illustrating the popularity of
tax-exempt cash investments.

In the first quarter of 1994 there was a shift in the outlook for the economy
and, in turn, short-term interest rates. Signs of economic strength prompted the
Federal Reserve (the "Fed") to twice "tighten" or increase short-term interest
rates, moving the Federal Funds rate target from 3.0% to 3.50%. The Fed again
tightened twice (in mid-April and mid-May) moving the Federal Funds target from
3.50% to 4.25%. The municipal money market reacted to the Fed policy with a
corresponding back-up in rates, which was somewhat exacerbated by $3.2 million
of new fixed-rate supply offered by the State of California in mid-February.
With renewed concerns of economic recovery and inflation, investors immediately
began to demand higher liquidity premiums to invest further out the yield curve,
causing rates on one-year municipal notes to rise to their highest levels since
June, 1992. For example, the Bond Buyer Note Index, a proxy for one-year
municipal notes, started the period at 2.55% and steadily increased over 1.20%
to end the period at 3.75%. Although yields on twelve-month tax-free securities
did rise, they did not rise by the same magnitude as on comparable maturity
taxable instruments. In November, the one-year tax-exempt note yield was 76% of
the taxable yield; in May it was 68%.*

In this environment of increasing money market interest rates, the Fund's
average portfolio maturity was shortened from the 70-day range at the beginning
of December, 1993, to the 50-day range in May, 1994. Looking ahead to the second
half of 1994, we expect short-term rates to continue to rise as the U.S. economy
continued its solid and sustainable recovery. If rates do, in fact, rise this
year, we will continue to keep the average maturity short and the portfolio
liquid while choosing carefully and selectively along the yield curve as
attractive fixed income opportunities appear.

* The direction of rates on tax-free variable rate demand notes (VRDNs), which
  comprise 50% of the Fund's assets, increased as well over the period. VRDNs
  started the period at 2.20% and increased 0.50% to 2.90% by May 31, 1994.
  However, because VRDNs are particularly affected by a variety of supply and
  demand seasonal factors, VRDN yields displayed significant volatility over the
  period.

NOTES TO FINANCIAL STATEMENTS
MAY 31, 1994
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Cash Trust Series, Inc. (the "Corporation"), is registered under the Investment
Company Act of 1940, as amended (the "Act"), as an open-end management
investment company. The Corporation consists of four portfolios. The financial
statements included herein present only those of Municipal Cash Series (the
"Fund"). The financial statements of the other portfolios are presented
separately. The assets of each portfolio are segregated and a shareholder's
interest is limited to the portfolio in which shares are held.

Effective June 15, 1993, shareholders approved the reorganization of the Fund as
a portfolio of Cash Trust Series, Inc., a Maryland corporation.

(2) SIGNIFICANT ACCOUNTING POLICIES

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

A. INVESTMENT VALUATIONS--The Fund's use of the amortized cost method to value
   its portfolio securities is in accordance with Rule 2a--7 under the Act.

B. INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS--Interest income and expenses
   are accrued daily. Bond premium and discount, if applicable, are amortized as
   required by the Internal Revenue Code, as amended (the "Code"). Distributions
   to shareholders are recorded on the ex-dividend date.

C. FEDERAL TAXES--It is the Fund's policy to comply with the provisions of the
   Code applicable to regulated investment companies and to distribute to
   shareholders each year substantially all of its tax-exempt income.
   Accordingly, no provisions for federal tax are necessary.

D. WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS--The Fund may engage in
   when-issued or delayed delivery transactions. A Fund records when-issued
   securities on the trade date and maintains security positions such that
   sufficient liquid assets will be available to make payment for the securities
   purchased. Securities purchased on a when-issued or delayed delivery basis
   are marked to market daily and begin earning interest on the settlement date.

E. DEFERRED EXPENSES--The costs incurred by the Fund with respect to
   registration of its shares in its first fiscal year, excluding the initial
   expense of registering the shares, have been deferred and are being amortized
   using the straight-line method over a period of five years from the Fund's
   commencement date.

F. OTHER--Investment transactions are accounted for on the trade date.

Services ("FSS"), the Fund will pay FSS up to 0.25 of 1% of average net assets

INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

To the Board of Directors of

CASH TRUST SERIES, INC. and Shareholders of
MUNICIPAL CASH SERIES:

We have audited the accompanying statement of assets and liabilities of
Municipal Cash Series (one of the portfolios comprising Cash Trust Series,
Inc.), including the portfolio of investments, as of May 31, 1994, the related
statement of operations for the year then ended, the statement of changes in net
assets for the years ended May 31, 1994 and 1993, and the financial highlights
for each of the years in the five-year period ended May 31, 1994. 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. Our procedures included confirmation of the securities owned as of
May 31, 1994, 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, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Municipal Cash
Series as of May 31, 1994, the results of its operations, the changes in its net
assets, and its financial highlights for the respective stated periods in
conformity with generally accepted accounting principles.

PRESIDENT'S MESSAGE
- --------------------------------------------------------------------------------

Dear Shareholder:

I am pleased to present the Annual Report to Shareholders for Prime Cash Series
(the "Fund"), which covers the twelve-month period ended May 31, 1994. The
Report includes the Investment Review and Financial Statements, which contain
the Portfolio of Investments.

Prime Cash Series pursues current income--along with the additional advantages
of daily liquidity and stability of principal*--through a diversified portfolio
of high-quality money market securities. At the end of the period, the portfolio
was invested primarily in commercial paper (45.7%) and variable rate obligations
(29.7%). It also held positions in repurchase agreements (20.9%), as well as
certificates of deposit and a bank note.

At the end of the period, the Fund's net assets stood at $791 million. Dividends
paid to shareholders during the period totaled $19.9 million, or $0.02 per
share.

Thank you for putting your cash to work through Prime Cash Series. Please
contact your investment representative if you have any questions about the Fund.
We will continue to keep you up to date on your investment progress.

Sincerely,

Richard B. Fisher
President
July 15, 1994

* As a money market mutual fund, the Fund is managed to pursue a stable share
  price of $1.00, although there is no guarantee that it will do so.


INVESTMENT REVIEW
- --------------------------------------------------------------------------------

Prime Cash Series (the "Fund"), invests exclusively in money market instruments
maturing in thirteen months or less. The average maturity of these securities,
computed on a dollar-weighted basis, is restricted to 90 days or less. Portfolio
securities must be rated in one of the two highest short-term rating categories
by one or more nationally recognized statistical rating organizations or be of
comparable quality to securities having such ratings. Typical security types
include, but are not limited to, commercial paper, certificates of deposit, time
deposits, Eurodollar certificates of deposit, variable rate instruments and
repurchase agreements.

The pace of U.S. economic activity has been moderate over the past year except
for a spurt of strength in the fourth quarter of 1993. Employment seems to be
making modest but steady gains while personal income and personal spending have
experienced minor upticks. From a manufacturing vantage point, industrial
production, capacity utilization, and durable goods orders have all begun to
rebound. In this mild recovery, both the Consumer Price Index, ("CPI") and the
Producer Price Index, ("PPI") have been contained, indicating that inflation
remains under control.

The target average maturity range for Prime Cash Series has gone from its
maximum of 50-60 days in November, 1993, to its current 30-40 day range. This
reflects our continuing bias that the money market yield curve is fairly steep,
and value can be obtained through both structure as well as by stepping out the
curve a bit. In structuring the Fund, there is continued emphasis placed on
positioning 25% 30% of the Fund's assets in variable rate demand notes and
accomplishing a modest barbell structure.

Defensive positioning has proven helpful since October, 1993. The Federal
Reserve ("the Fed") has raised short-term rates four times since February 4,
1994. The Fed Funds target has gone from 3% to 4.25% and the discount rate has
increased from 3% to 3.5%. Despite the fact that CPI and PPI indicate moderate
inflationary levels, the Fed has begun to fight "inflation expectations." Given
the continued path of recovery, the Fed has now declared a neutral stance.

For the fiscal year ending May 31, 1994, the net assets of Prime Cash Series
decreased from $796.8 million to $791.1 million while the seven-day net yield
increased from 2.27% to 3.18%.* The effective average maturity of the Fund on
May 31 was 35 days.

* Performance quoted represents past performance and is not indicative of future
  returns.

PRIME CASH SERIES
NOTES TO FINANCIAL STATEMENTS
MAY 31, 1994
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Cash Trust Series, Inc. (the "Corporation"), is registered under the Investment
Company Act of 1940, as amended (the "Act"), as an open-end management
investment company. The Corporation consists of four portfolios. The financial
statements included herein present only those of Prime Cash Series (the "Fund").
The financial statements of the other portfolios are presented separately. The
assets of each portfolio are segregated and a shareholder's interest is limited
to the portfolio in which shares are held.

Effective June 15, 1993, shareholders approved the reorganization of the Fund as
a portfolio of Cash Trust Series, Inc., a Maryland corporation.

(2) SIGNIFICANT ACCOUNTING POLICIES

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

A. INVESTMENT VALUATIONS--The Fund's use of the amortized cost method to value
   its portfolio securities is in accordance with Rule 2a-7 under the Act.

B. REPURCHASE AGREEMENTS--It is the policy of the Fund to require the custodian
   bank to take possession, to have legally segregated in the Federal Reserve
   Book Entry System or to have segregated within the custodian bank's vault,
   all securities held as collateral in support of repurchase agreement
   investments. Additionally, procedures have been established by the Fund to
   monitor, on a daily basis, the market value of each repurchase agreement's
   underlying collateral to ensure the value at least equals the principal
   amount of the repurchase agreement, including accrued interest.

   The Fund will only enter into repurchase agreements with banks and other
   recognized financial institutions, such as broker/dealers, which are deemed
   by the Fund's adviser to be creditworthy pursuant to guidelines established
   by the Board of Directors ("Directors"). Risks may arise from the potential
   inability of counterparties to honor the terms of the repurchase agreement.
   Accordingly, the Fund could receive less than the repurchase price on the
   sale of collateral securities.

C. INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS--Interest income and expenses
   are accrued daily. Bond premium and discount, if applicable, are amortized as
   required by the Internal Revenue Code, as amended (the "Code"). Distributions
   to shareholders are recorded on the ex-dividend date.

D. FEDERAL TAXES--It is the Fund's policy to comply with the provisions of the
   Code applicable to regulated investment companies and to distribute to
   shareholders each year substantially all of its taxable income. Accordingly,
   no provision for federal tax are necessary.


PRIME CASH SERIES
- --------------------------------------------------------------------------------

E. WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS--The Fund may engage in
   when-issued or delayed delivery transactions. A Fund records when-issued
   securities on the trade date and maintains security positions such that
   sufficient liquid assets will be available to make payment for the securities
   purchased. Securities purchased on a when-issued or delayed delivery basis
   are marked to market daily and begin earning interest on the settlement date.

F. DEFERRED EXPENSES--The costs incurred by the Fund with respect to
   registration of its shares in its first fiscal year, excluding the initial
   expense of registering the shares, have been deferred and are being amortized
   using the straight-line method over a period of five years from the Fund's
   commencement date.

G. OTHER--Investment transactions are accounted for on the trade date.

(3) CAPITAL STOCK

At May 31, 1994, there were 12,500,000,000 shares of $0.001 par value capital
stock authorized. Capital paid in aggregated $791,147,071. Transactions in
capital stock were as follows:

(4) INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISORY FEE--Federated Advisers, the Fund's investment adviser (the
"Adviser"), receives for its services an annual investment advisory fee equal to
0.50 of 1% of the Fund's average daily net assets. The Adviser may voluntarily
choose to waive a portion of its fee. The Adviser can modify or terminate this
voluntary waiver at any time at its sole discretion.

ADMINISTRATIVE FEE--Federated Administrative Services ("FAS") provides the Fund
with administrative personnel and services. Prior to March 1, 1994, these
services were provided at approximate cost. Effective March 1, 1994, the FAS fee
is based on the level of average aggregate daily net assets of all funds advised
by subsidiaries of Federated Investors for the period. The administrative fee
received during any fiscal year shall be at least $125,000 per portfolio and
$30,000 per each additional class of shares.

DISTRIBUTION AND SHAREHOLDER SERVICES FEES--The Fund has adopted a Distribution
Plan (the "Plan") pursuant to Rule 12b-1 under the Act. Under the terms of the
Plan, the Fund will reimburse Federated Securities Corp. ("FSC"), the principal
distributor, from the net assets of the Fund to finance

Under the terms of a Shareholder Services Agreement with Federated Shareholder
Services ("FSS"), the Fund will pay FSS up to 0.25 of 1% of average net assets
of the Fund for the period. This fee is to obtain certain personal services for
shareholders and to maintain shareholder accounts.

based on the size, type and number of accounts and transactions made by
shareholders.

INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

To the Board of Directors of

CASH TRUST SERIES, INC. and Shareholders of

PRIME CASH SERIES:

We have audited the accompanying statement of assets and liabilities of Prime
Cash Series (one of the portfolios comprising Cash Trust Series, Inc.),
including the portfolio of investments, as of May 31, 1994, the related
statement of operations for the year then ended, the statement of changes in net
assets for the years ended May 31, 1994 and 1993 and the financial highlights
for each of the years in the five-year period ended May 31, 1994. 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. Our procedures included confirmation of the securities owned as of
May 31, 1994 by correspondence with the custodian. 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, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Prime Cash Series as
of May 31, 1994, the results of its operations, the changes in its net assets,
and its financial highlights for the respective stated periods in conformity
with generally accepted accounting principles.

PRESIDENT'S MESSAGE
- --------------------------------------------------------------------------------

Dear Shareholder:

I am pleased to present the Annual Report to Shareholders for Treasury Cash
Series (the "Fund"), which covers the twelve-month period ended May 31, 1994.
The report includes the Investment Review and Financial Statements, which
contain the Portfolio of Investments.

Treasury Cash Series pursues current income--along with the additional
advantages of daily liquidity and stability of principal*--through some of the
most stable investments available. The Fund's diversified portfolio may consist
of short-term U.S. Treasury obligations or repurchase agreements backed by these
obligations. Because of their yield advantage, repurchase agreements continued
to account for over 74% of the portfolio at the end of the reporting period.

At the end of the period, the Fund's net assets stood at $427 million. Dividends
paid to shareholders during the period totaled $11.3 million, or $0.02 per
share.

As always, we thank you for putting your cash to work through Treasury Cash
Series. Please contact your investment representative if you have any questions
about the Fund. We will continue to keep you up to date on your investment.

Sincerely,

Richard B. Fisher
President
July 15, 1994

* As a money market mutual fund, the Fund is managed to pursue a stable share
  price of $1.00, although there is no guarantee that it will do so.


INVESTMENT REVIEW
- --------------------------------------------------------------------------------

Treasury Cash Series (the "Fund"), which is rated AAAm by Standard & Poor's
Corporation and Aaa by Moody's Investors Service, Inc.*, is invested in direct
obligations of the U.S. Treasury, either in the form of notes and bills or as
collateral for repurchase agreements. Recently, the Fund has been managed with a
somewhat conservative average maturity of 30-40 days.

The reporting period brought the first changes in Federal Reserve (the "Fed")
policy since September, 1992. The Fed tightened monetary policy by increasing
the Federal Fund target rate from 3% to 4.25% over the period from February
through May. The moves were viewed as being preemptive strikes against the
threat of inflation by removing the stimulus that the Fed had been providing to
the economy through an overly accommodative policy stance. With inflation
apparently under control and economic growth slowing slightly, Fed policy
appears to be on hold temporarily at its current neutral stance. However, rising
capacity utilization rates, commodity prices, and other inflation measures may
prompt another tightening by the Fed sometime this summer in order to keep
inflation firmly in check.

Prior to the policy changes by the Fed, movements in short-term rates were
largely driven by market sentiment during the reporting period. The rate on the
three-month Treasury bill fell from 3.1% at the end of May, 1993, to 3.0% at the
end of September. The rate then rose to 3.2% by the end of November and then
returned to near 3% by the end of January. Once the Fed began tightening in
February, the three-month Treasury bill rate then rose steadily to 4.25% by the
end of May, 1994.

As a yield advantage continued to exist for investments in repurchase agreements
versus direct investments in short-term Treasury securities. The barbell
structure of the Fund was maintained over the period, combining a significant
position in overnight repurchase agreements with Treasury securities with longer
maturities of six to twelve months.

Over the reporting period, the Fund's average maturity drifted shorter in the
face of the somewhat uncertain environment created by the Fed. In light of the
expectations of additional tightenings in monetary policy, the Fund is expected
to continue to maintain its conservative posture in the near future, while
maximizing performance through ongoing relative value analysis. However,
changing economic and market developments are continuously monitored to best
serve our clients attracted to the short-term U.S. government market.

* Ratings are subject to change.

TREASURY CASH SERIES
NOTES TO FINANCIAL STATEMENTS
MAY 31, 1994
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Cash Trust Series, Inc. (the "Corporation"), is registered under the Investment
Company Act of 1940, as amended (the "Act"), as an open-end management
investment company. The Corporation consists of four portfolios. The financial
statements included herein present only those of Treasury Cash Series (the
"Fund"). The financial statements of the other portfolios are presented
separately. The assets of each portfolio are segregated and a shareholder's
interest is limited to the portfolio in which shares are held.

Effective June 15, 1993, shareholders approved the reorganization of the Fund as
a portfolio of Cash Trust Series, Inc., a Maryland corporation.

(2) SIGNIFICANT ACCOUNTING POLICIES

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

A. INVESTMENT VALUATIONS--The Fund's use of the amortized cost method to value
   its portfolio securities is in accordance with Rule 2a-7 under the Act.

B. REPURCHASE AGREEMENTS--It is the policy of the Fund to require the custodian
   bank to take possession, to have legally segregated in the Federal Reserve
   Book Entry System or to have segregated within the custodian bank's vault,
   all securities held as collateral in support of repurchase agreement
   investments. Additionally, procedures have been established by the Fund to
   monitor, on a daily basis, the market value of each repurchase agreement's
   underlying collateral to ensure the value at least equals the principal
   amount of the repurchase agreement, including accrued interest.

   The Fund will only enter into repurchase agreements with banks and other
   recognized financial institutions, such as broker/dealers, which are deemed
   by the Fund's adviser to be creditworthy pursuant to guidelines established
   by the Board of Directors ("Directors").

C. INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS--Interest income and expenses
   are accrued daily. Bond premium and discount, if applicable, are amortized as

INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

To the Board of Directors of

CASH TRUST SERIES, INC. and Shareholders of
TREASURY CASH SERIES:

We have audited the accompanying statement of assets and liabilities of Treasury
Cash Series (one of the portfolios comprising Cash Trust Series, Inc.),
including the portfolio of investments, as of May 31, 1994, the related
statement of operations for the year then ended, the statement of changes in net
assets for the years ended May 31, 1994 and 1993, and the financial highlights
for each of the years in the five-year period ended May 31, 1994. 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. Our procedures included confirmation of the securities owned as of
May 31, 1994 by correspondence with the custodian. 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, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Treasury Cash Series
as of May 31, 1994, the results of its operations, the changes in its net assets
and its financial highlights for the respective stated periods in conformity
with generally accepted accounting principles.
