Dear Shareholder:


We are pleased to provide you with the June 30, 1999, Semi-Annual Report of the
Merrimac Series. The funds are part of a master-feeder fund structure under
which each fund invests its assets in a master portfolio having identical
investment objectives. The fund structure is described further in the footnotes
to the enclosed financial statements.

We are pleased to have introduced two new funds during the first half of 1999
and will continue to develop our fund offerings to respond to your needs. The
Merrimac Treasury Plus Series commenced operations on January 22, 1999 and the
Merrimac U.S. Government Series commenced operations on June 29, 1999. As of
June 30, four money market funds are in operation. The Merrimac Cash Series and
the Merrimac U.S. Government Series each invest in master portfolios which are
sub-advised by Allmerica Asset Management, Inc. The Merrimac Treasury Series and
the Merrimac Treasury Plus Series each invest in master portfolios which are
sub-advised by M&I Investment Management Corp.

Thank you for your support and participation. We look forward to continuing to
serve you in the future.


Very truly yours,

/S/ George A. Rio

George A. Rio
President

                                 Merrimac Series

                    Notes to Financial Statements (Unaudited)
     ---------------------------------------------------------------------------


(1)  Significant Accounting Policies

     The Merrimac Series (the "Trust") is organized as a Delaware business trust
     and is registered under the Investment Company Act of 1940, as an open-end
     management investment company. The Merrimac Cash Series (the "Cash
     Series"), the Merrimac Treasury Series (the "Treasury Series"), the
     Merrimac Treasury Plus Series (the "Treasury Plus Series"), the Merrimac
     U.S. Government Series (the "Government Series") and the Merrimac
     Short-Term Asset Reserve Series (the "STAR Series") (collectively, the
     "Funds") are separate diversified investment portfolios or series of the
     Trust. The Funds consist of three classes of shares, the Premium Class, the
     Institutional Class and the Investment Class. The Treasury Plus Series
     commenced operations on January 22, 1999 and the Government Series
     commenced operations on June 29, 1999. The STAR Series is currently
     inactive.

     The Funds seek to achieve their investment objective by investing all of
     their investable assets in the Merrimac Cash Portfolio (the "Cash
     Portfolio"), the Merrimac Treasury Portfolio (the "Treasury Portfolio"),
     the Merrimac Treasury Plus Portfolio (the "Treasury Plus Portfolio"), and
     the Merrimac U.S. Government Portfolio (the "Government Portfolio"),
     respectively. The Portfolios are each an open-end investment management
     company and a series of the Merrimac Master Portfolio, and are hereinafter
     referred to singly as a "Portfolio," and collectively as the "Portfolios."
     Each Portfolio seeks to achieve a high level of current income, consistent
     with the preservation of capital and liquidity. Each Fund has the same
     investment objective as the Portfolio into which it invests. The
     performance of each Fund is directly affected by the performance of the
     Portfolio into which it invests. The financial statements of the Portfolios
     are included elsewhere in this report and should be read in conjunction
     with the Funds' financial statements. At June 30, 1999, the investment by
     the Cash Series, the Treasury Series, Treasury Plus Series, and the
     Government Series represent ownership of proportionate interests of 23.1%,
     100%, 100%, and 100%, respectively, of their corresponding portfolios.

     The policies of the Funds, except the STAR series, are designed to maintain
     a stable net asset value of $1.00 per share. They have adopted certain
     investment, valuation, dividend and distribution policies which conform to
     general industry practice, to enable them to do so. However, there is no
     assurance that they will be able to maintain a stable net asset value.

     The following is a summary of significant accounting policies followed by
     the Funds in the preparation of their financial statements. The preparation
     of financial statements in accordance with generally accepted accounting
     principles ("GAAP") requires management to make estimates and assumptions
     that affect the reported amounts and disclosures in the financial
     statements. Actual results could differ from those estimates.

     A. Investment Security Valuations

     The Funds record their investment in the Portfolios at value. Valuation of
     securities by the Portfolios is discussed in Note 1 of the Portfolios'
     Notes to Financial Statements, which are included elsewhere in this report.

     B. Securities Transactions and Income

     The Portfolios record securities transactions as of the trade date.
     Interest income, including the accretion of discount or the amortization of
     premium, is recognized when earned. Gains or losses on sales of securities
     are calculated on the identified cost basis. Each Fund's net investment
     income consists of its pro rata share of the net investment income of its
     corresponding Portfolio, less all expenses of the Fund determined in
     accordance with GAAP.

     C. Federal Income Taxes

     Each Fund intends to qualify annually as a regulated investment company
     under Subchapter M of the Internal Revenue Code, and thus not be subject to
     income taxes. To qualify, each Fund must distribute all of its taxable
     income for its fiscal year and meet certain other requirements.
     Accordingly, no provision for federal income taxes is required.

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


     D. Deferred Organization Expense

     Costs incurred by the Cash Series and Treasury Series in connection with
     their organization and initial registration are being amortized on a
     straight-line basis over a five year period beginning at the commencement
     of operations of each Fund.

     E. Expense Allocation

     Expenses directly attributable to a Fund are charged to that Fund. Expenses
     not directly attributable to a specific Fund are allocated, based on
     relative net assets, to each of the Funds.

(2)  Dividends and Distributions to Shareholders

     Dividends on the shares of the Funds are declared each business day to
     shareholders of record on that day, and paid or reinvested as of the last
     business day of the month. Distributions of net realized gains, if any, may
     be declared annually. Dividends and distributions are determined in
     accordance with federal income tax regulations, which may differ from GAAP.

(3)  Shareholder Servicing and Distribution Plans

     The Trust has adopted a Shareholder Servicing Plan with respect to the
     Institutional Class under which certain service organizations may be
     compensated for providing shareholder accounting and other administrative
     services for their clients. The Institutional Class may pay an annual fee
     of up to 0.25% of the value of the assets that an organization services on
     behalf of its clients. Under a Distribution Plan, the Investment Class may
     pay an annual distribution fee of up to 0.25% of the value of the assets
     that an organization invests in the Funds on behalf of its clients. The
     Investment Class of each Fund, and the Premium Class of the Treasury Plus
     Series, and the Government Series have not yet commenced operations.

(4)  Management Fee and Affiliated Transactions

     The Merrimac Master Portfolio retains Investors Bank & Trust Company
     ("Investors Bank") as investment adviser. Allmerica Asset Management, Inc.
     ("AAM") serves as the sub-adviser to the Cash Portfolio and U.S. Government
     Portfolio and M&I Investment Management Corp. ("M&I") serves as sub-adviser
     to the Treasury Portfolio and Treasury Plus Portfolio. The Funds pay no
     direct fees for such services, but indirectly bear their pro rata share of
     the compensation paid by the Portfolios. See Note 2 of the Portfolios'
     Notes to Financial Statements which are included elsewhere in this report.

     Investors Bank or its subsidiary, IBT Fund Services (Canada), Inc. serves
     as administrator, custodian, fund accounting agent, and transfer agent to
     the Trust. For these services, Investors Bank and its subsidiary are paid a
     monthly fee at an annual rate of 0.01% of the average daily net assets of
     each Fund.

     Certain trustees and officers of the Trust are directors or officers of
     Investors Bank. The Funds do not pay compensation to the trustees or
     officers who are affiliated with Investors Bank.

(5)  Shares of Beneficial Interest

     The Declaration of Trust permits the Trustees to issue an unlimited number
     of shares of beneficial interest for each Fund having a par value of $0.001
     per share. Transactions in Fund shares for each class were as follows:

Notes to the Schedule of Investments:

*    Variable rate securities - maturity dates on these securities reflect the
     next interest rate reset date or, when applicable, the put date or final
     maturity date. Yield to maturity for these securities is determined on the
     date of the most recent interest rate change.

**   On August 10, 1999, management of the Portfolio was notified that the
     short-term debt ratings of General American Life Insurance Company
     ("GALIC") had been downgraded by certain rating agencies and management
     promptly exercised the Portfolio's seven-day demand rights on the funding
     agreement with GALIC scheduled to mature on March 16, 2000. Subsequently,
     because of short-term liquidity problems, GALIC was placed under
     administrative supervision by the Missouri Department of Insurance. On
     August 17, 1999, in anticipation of a default by GALIC, the Portfolio
     agreed to extend for thirty days the date for repayment of this refunding
     agreement and, in consideration for such extension, received a partial
     payment of $1.5 million on August 18, 1999 and an increase in the interest
     rate payable on the balance outstanding. Subsequently, it was announced
     that Metropolitan Life Insurance Company ("MetLife") and GenAmerican Corp.,
     the parent of GALIC, had agreed to terms of a cash purchase of GenAmerican
     Corp. by MetLife.

                    Notes to Financial Statements (Unaudited)
- --------------------------------------------------------------------------------


(1)      Significant Accounting Policies

         The Merrimac Master Portfolio (the "Portfolio Trust") is organized as a
         common law trust under the laws of the State of New York and is
         registered under the Investment Company Act of 1940 ("1940 Act"), as an
         open-end management investment company with its principal offices in
         the Cayman Islands. The Merrimac Cash Portfolio (the "Cash Portfolio"),
         the Merrimac Treasury Portfolio (the "Treasury Portfolio"), the
         Merrimac Treasury Plus Portfolio (the "Treasury Plus Portfolio") and
         the Merrimac U.S. Government Portfolio (the "Government Portfolio" and
         collectively, the "Portfolios") are separate diversified investment
         series of the Portfolio Trust.

         The following is a summary of significant accounting policies followed
         by the Portfolio Trust in the preparation of its financial statements.
         The preparation of financial statements in accordance with generally
         accepted accounting principles ("GAAP") requires management to make
         estimates and assumptions that affect the reported amounts and
         disclosures in the financial statements. Actual results could differ
         from those estimates.

         A. Investment Security Valuations

         Portfolio securities are valued using the amortized cost method, which
         involves initially valuing an investment at its cost and thereafter
         assuming a constant amortization to maturity of any premium or
         discount. This method results in a value approximating market value.
         Each Portfolio's use of amortized cost is subject to compliance with
         certain conditions specified under Rule 2a-7 of the 1940 Act.

         B. Securities Transactions and Income

         Interest income consists of interest accrued and discount earned
         (including both the original issue and market discount) less premium
         amortized on the investments of the Portfolios, accrued ratably to the
         date of maturity. Purchases, maturities and sales of money market
         instruments are accounted for on the date of transaction. Expenses of
         the Portfolios are accrued daily. All investment income, expenses, and
         realized capital gains and losses of the Portfolios are allocated pro
         rata to their investors.

         C. Federal Income Taxes

         Each Portfolio is considered a partnership under the U.S. Internal
         Revenue Code. Accordingly, no provision for federal income taxes is
         necessary. Each Portfolio also intends to conduct its operations such
         that each investor will be able to qualify as a regulated investment
         company.

         D. Repurchase Agreements

         It is the policy of the Portfolio Trust to require the custodian bank
         to take possession of all securities held as collateral in support of
         repurchase agreement investments. Additionally, procedures have been
         established to monitor the daily market value of the repurchase
         agreement's underlying investments to ensure the existence of a proper
         level of collateral. The Treasury Portfolio does not invest in
         repurchase agreements.

         E. Deferred Organization Expense

         Costs incurred by the Cash Portfolio and the Treasury Portfolio in
         connection with its organization and initial registration are being
         amortized on a straight-line basis over a five year period beginning at
         the commencement of operations of each Portfolio.

(2)      Management Fee and Affiliated Transactions

         The Portfolios retain Investors Bank & Trust Company ("Investors Bank")
         as investment adviser to continuously review and monitor the
         Portfolios' investment program. Investors Bank also serves as custodian
         for the Portfolio Trust. Investor's Fund Services (Ireland) Limited, a
         subsidiary of Investors Bank, serves as administrator. IBT Fund
         Services (Canada) Inc., a subsidiary of Investors Bank, serves as fund
         accounting and transfer agent. For these services, Investors Bank and
         its subsidiaries are paid a monthly fee at an annual rate of 0.17% of
         the average daily assets of the Portfolios.

(4)      Line of Credit

         The Portfolios participate in a $100 million line of credit agreement
         with a group of banks. Borrowings will be made solely to facilitate the
         handling of unusual and/or unanticipated short-term cash requirements.
         Interest is charged to each portfolio based on its borrowings at an
         amount above the Federal Funds rate. In addition, a fee computed at an
         annual rate of 0.08% on the daily unused portion of the line of credit
         is allocated among the portfolios. There were no borrowings during the
         period ended June 30, 1999.
