This Amendment No. 8 to the Registration Statement on Form N-1A (the
"Amendment") has been filed by the Registrant pursuant to Section 8(b) of the
Investment Company Act of 1940, as amended (the "1940 Act"), and Rule 8b-16
thereunder. However, beneficial interests in the series of the Registrant are
not registered under the Securities Act of 1933, as amended (the "1933 Act"),

common or commingled trust funds or similar organizations or entities that are
"accredited investors" within the meaning of Regulation D under the 1933 Act.
The Amendment does not constitute an offer to sell, or the solicitation of an
offer to buy, any beneficial interests in any series of the Registrant.

This Amendment relates only to the Standish Fixed Income Portfolio,
Standish Diversified Income Portfolio, Standish Global Fixed Income Portfolio
and Standish Short Term Asset Reserve Portfolio and does not affect the
registration of any other series of the Registrant.

THIS PART A DOES NOT CONSTITUTE AN OFFER TO SELL, OR THE SOLICITATION OF AN
OFFER TO BUY, ANY BENEFICIAL INTERESTS IN STANDISH FIXED INCOME PORTFOLIO.

The Portfolio's Part B, of even date herewith, is incorporated by
reference into this Part A.

Responses to Items 1 through 3, 5 and 9 have been omitted pursuant to
paragraph 2(b) of Instruction B of the General Instructions to Form N-1A.

RISKS.

The Portfolio Trust incorporates by reference the information concerning

<PAGE>

The Portfolio's securities trades, pricing and accounting services and
other operations could be adversely affected if the computer systems of the
advisers, distributor, custodian and transfer agent were unable to recognize
dates after 1999. The cost of addressing the year 2000 issue may adversely
affect the issues of individual securities held by the Portfolio. The advisers
and other service providers have told the Portfolio that they are taking action
to prevent, and do not expect the Portfolio to suffer from, material year 2000
problems.

ITEM 6. MANAGEMENT, ORGANIZATION AND CAPITAL STRUCTURE.

MANAGEMENT

The Portfolio Trust incorporates by reference information concerning the
Portfolio's and the Portfolio Trust's management from "The Investment Advisers"
in the Prospectus.

Administrator of the Portfolio. IBT Trust Company (Cayman) Ltd., P.O. Box
501, Grand Cayman, Cayman Islands, BWI, serves as the administrator to the
Portfolio (the "Portfolio Administrator") pursuant to a written administration
agreement with the Portfolio Trust on behalf of the Portfolio. The Portfolio
Administrator provides the Portfolio Trust with office space for managing its
affairs, and with certain clerical services and facilities. The Portfolio's
administration agreement can be terminated by either party on not more than 60
days' written notice.

ORGANIZATION

The Portfolio Trust is a no-load, open-end management investment company
which was organized as a master trust fund under the laws of the State of New
York on January 18, 1996. Beneficial interests in the Portfolio Trust are
divided into separate sub-trusts or series, each having distinct investment
objectives and policies, one of which, the Portfolio, is described herein.
Beneficial interests in the Portfolio are issued solely in transactions that are
exempt from registration under the 1933 Act. Investments in the Portfolio Trust
may only be made by investment companies, insurance company separate accounts,
common or commingled trust funds or similar organizations or entities that are
"accredited investors" within the meaning of Regulation D under the 1933 Act.
This Registration Statement does not constitute an offer to sell, or the
solicitation of an offer to buy, any "security" within the meaning of the 1933
Act.

CAPITAL STRUCTURE

The Portfolio Trust incorporates by reference information concerning the
master-feeder structure from "Fund Details - Master/feeder structure" in the
Prospectus.

A-2
<PAGE>

The Portfolio Trust was organized as a trust under the laws of the State
of New York on January 18, 1996. Under the Declaration of Trust, the Trustees
are authorized to issue beneficial interests in separate series of the Portfolio
Trust. Each investor is entitled to a vote in proportion to the amount of its
investment in the Portfolio. Investments in the Portfolio may not be
transferred, but an investor may withdraw all or any portion of his investment
at any time at net asset value. Investors in the Portfolio (e.g., investment
companies, insurance company separate accounts and common and commingled trust
funds) will not be liable for the obligations of the Portfolio although they
will bear the risk of loss of their entire respective interests in the
Portfolio. However, there is a risk that interest-holders in the Portfolio may
be held personally liable as partners for the Portfolio's obligations. Because
the Portfolio Trust's Declaration of Trust disclaims interest-holder liability
and provides for indemnification against such liability, the risk of an investor
in the Portfolio incurring financial loss on account of such liability is
limited to circumstances in which both inadequate insurance existed and the
Portfolio itself was unable to meet its obligations.

The Portfolio Trust reserves the right to create and issue any number of
series, in which case investments in each series would participate equally in
earnings and assets of the particular series.

Investments in the Portfolio have no pre-emptive or conversion rights and
are fully paid and non-assessable, except as set forth above. The Portfolio
Trust is not required and has no current intention to hold annual meetings of
investors, but the Portfolio Trust will hold special meetings of investors when
in the judgment of the Trustees it is necessary or desirable to submit matters
for an investor vote. Changes in fundamental policies will be submitted to
investors for approval. Investors have under certain circumstances (e.g., upon
application and submission of certain specified documents to the Trustees by a
specified percentage of the aggregate value of the Portfolio Trust's outstanding
interests) the right to communicate with other investors in connection with
requesting a meeting of investors for the purpose of removing one or more
Trustees. Investors also have the right to remove one or more Trustees without a
meeting by a declaration in writing by a specified number of investors. Upon
liquidation of a Portfolio, investors would be entitled to share pro rata in the
net assets of the Portfolio available for distribution to investors.

As of the date of this Part A, the Fund beneficially owned substantially
all of the then outstanding interests in the Portfolio and therefore controlled
the Portfolio.

Inquiries concerning the Portfolio should be made by contacting the
Portfolio at the Portfolio Trust's registered office in care of the Portfolio
Administrator, P.O. Box 501, Cardinal Avenue, George Town, Grand Cayman, Cayman
Islands, British West Indies.

ITEM 7. SHAREHOLDER INFORMATION

PRICING OF SECURITIES BEING OFFERED

The Portfolio Trust incorporates by reference information concerning the
calculation of the Portfolio's net asset value from "Investment and Account
Information - Valuation of shares" in the Prospectus.

The net asset value of the Portfolio is computed in U.S. dollars each day
on which the New York Stock Exchange ("NYSE") is open for trading ("Business
Day") (and on such other days as are deemed necessary in order to comply with
Rule 22c-1 under the 1940 Act). Currently, the NYSE is not open on weekends, New
Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. This
determination is made as of the close of regular trading on the NYSE which is
normally 4:00 p.m., New York time (the "Valuation Time"). If the NYSE closes
early, the Portfolio accelerates calculation of NAV and transaction deadlines to
that time.

Fixed income securities (other than money market instruments) for which
accurate market prices are readily available are valued at their current market
value on the basis of quotations, which may be furnished by a pricing service or
provided by dealers in such securities. Securities not listed on an exchange or
national securities market, certain mortgage-backed and asset-backed securities
and securities for which there were no reported transactions are valued at the
last quoted bid prices. Fixed income securities for which accurate market prices
are not readily available and all other assets are valued at fair value as
determined in good faith by Standish in accordance with procedures approved by
the Trustees, which may include the use of yield equivalents or matrix pricing.
Money market instruments with less than sixty days remaining to maturity when
acquired by the Portfolio are valued on an amortized cost basis unless the
Trustees determine that amortized cost does not represent fair value. If the
Portfolio acquires a money market instrument with more than sixty days remaining
to its maturity, it is valued at current market value until the sixtieth day
prior to maturity and will then be valued at amortized cost based upon the value
on such date unless the Trustees determine during such sixty-day period that
amortized cost does not represent fair value.

Each investor in the Portfolio may add to or reduce its investment in the
Portfolio on each Business Day. At each Valuation Time on each such Business
Day, the value of each investor's beneficial interest in the Portfolio will be
determined by multiplying the net asset value of the Portfolio by the
percentage, effective for that day, that represents that investor's share of the
aggregate beneficial interests in the Portfolio. Any additions or withdrawals,
which are to be effected on that day, will

A-4
<PAGE>

then be effected. The investor's percentage of the aggregate beneficial
interests in the Portfolio will then be recomputed as the percentage equal to
the fraction (i) the numerator of which is the value of such investor's
investment in the Portfolio as of the Valuation Time, on such Business Day plus
or minus, as the case may be, the amount of any additions to or withdrawals from
the investor's investment in the Portfolio effected on such Business Day, and
(ii) the denominator of which is the aggregate net asset value of the Portfolio
as of the Valuation Time, on such Business Day plus or minus, as the case may
be, the amount of the net additions to or withdrawals from the aggregate
investments in the Portfolio by all investors in the Portfolio. The percentage
so determined will then be applied to determine the value of the investor's
interest in the Portfolio as of the Valuation Time, on the following Business
Day.

PURCHASE OF SECURITIES BEING OFFERED

Beneficial interests in the Portfolio are issued solely in transactions
that are exempt from registration under the 1933 Act. See "Management,
Organization and Capital Structure" above.

An investment in the Portfolio may be made without a sales load by certain
eligible investors. All investments are made at the net asset value next
determined after an order and payment for the investment is received by the
Portfolio or its agent by the designated cutoff time for each accredited
investor. There is no minimum initial or subsequent investment in the Portfolio.
However, because the Portfolio intends to be as fully invested at all times as
is reasonably practicable in order to enhance the yield on its assets,
investments must be made in federal funds (i.e., monies credited to the account
of the Portfolio Trust's custodian bank by a Federal Reserve Bank). The
Portfolio Trust reserves the right to cease accepting investments in the
Portfolio at any time or to reject any investment order.

REDEMPTION OF SECURITIES BEING OFFERED

An investor in the Portfolio may withdraw all or any portion of its
investment at the net asset value next determined after receipt by the Portfolio
or its agent, by the close of trading (normally 4:00 p.m. Eastern Time) on the
NYSE or, as of such earlier times at which the Portfolio's net asset value is
calculated on each Business Day, by a withdrawal request in proper form. The
proceeds of a withdrawal will be paid by the Portfolio in federal funds normally
on the Business Day the withdrawal is effected, but in any event within five
Business Days following receipt of the request. The Portfolio reserves the right
to pay redemptions in kind. Investments in the Portfolio may not be transferred.

The right of any investor to receive payment with respect to any
withdrawal may be suspended or the payment of the withdrawal proceeds postponed
during any

A-5
<PAGE>

period in which the NYSE is closed (other than weekends or holidays) or trading
on such exchange is restricted, or, to the extent otherwise permitted by the
1940 Act, if an emergency exists.

DIVIDENDS AND DISTRIBUTIONS

The net income of the Portfolio shall consist of (i) all income accrued,
less the amortization of any premium, on the assets of the Portfolio, less (ii)
all actual and accrued expenses of the Portfolio determined in accordance with
generally accepted accounting principles ("Net Income"). Interest income
includes discount earned (including both original issue and market discount) on
discount paper accrued ratably to the date of maturity and any net realized
gains or losses on the assets of the Portfolio. All the Net Income of the
Portfolio is allocated pro rata among the investors in the Portfolio. The Net
Income is accrued daily and reflected in each investor's interest in the
Portfolio.

TAX CONSEQUENCES

Under the anticipated method of operation of the Portfolio, it is expected
that the Portfolio will not be subject to any U.S. federal or state income tax.
However, any investor in the Portfolio that is subject to U.S. federal income
taxation will take into account its share (as determined in accordance with the
governing instrument of the Portfolio) of the Portfolio's items of income, gain,
loss, deduction and credit in determining its income tax liability, if any. The
determination of such share will be made in a manner that is intended to comply
with the Internal Revenue Code of 1986, as amended (the "Code"), and applicable
tax regulations.

It is intended that the Portfolio's assets, income and distributions will
be managed in such a way that any investor in the Portfolio that is otherwise
eligible to be treated as a regulated investment company should be able to
satisfy the requirements of Subchapter M of the Code, assuming that the investor
invests all of its investment securities (as such term is used in the 1940 Act)
in the Portfolio.

data for the year ended December 31, 1998.

ITEM 14. CONTROL PERSONS AND PRINCIPAL HOLDERS OF SECURITIES.

B-2
<PAGE>

As of the date of this Part B, the Trustees and officers of the Portfolio
Trust as a group beneficially owned (i.e., had voting and/or investment power)
less than 1% of the then outstanding interests of the Portfolio. As of the date
of this Part B, the Standish Fixed Income Fund beneficially owned substantially
all of the then outstanding interests of the Portfolio and therefore controlled
the Portfolio. Accordingly, the Fund may be able to take actions with respect to
the Trust (i.e., elect Trustees or approve an advisory agreement) without the
approval of other investors in the Portfolio. The Standish Fixed Income Fund is
a separate diversified series of the Standish, Ayer & Wood Investment Trust, an
open-end investment company, located at One Financial Center, Boston, MA 02111.

Registered investment companies investing in the Portfolio have informed
the Portfolio that whenever such an investor is requested to vote on matters
pertaining to the fundamental policies of the Portfolio, the investment company
will hold a meeting of shareholders and will cast its votes as instructed by the
company's shareholders.

ITEM 15. INVESTMENT ADVISORY AND OTHER SERVICES.

The Portfolio Trust incorporates by reference information concerning the
Portfolio's and the Portfolio Trust's investment advisory and other services
from "Management" in the SAI.

Massachusetts 02116, serves as custodian of all cash and securities of the
Portfolio.

Portfolio and Its Investors" in the SAI.

ITEM 18. PURCHASE, REDEMPTION AND PRICING OF SECURITIES BEING OFFERED.

B-3
<PAGE>

Beneficial interests in the Portfolio are issued solely in transactions
that are exempt from registration under the Securities Act of 1933. See
"Management, Organization and Capital Structure," "Shareholder Information -
Purchase of Securities Being Offered" and "Redemption of Securities Being
Offered" in Part A.

The Portfolio Trust incorporates by reference information concerning the
Portfolio's and the Portfolio Trust's pricing of interests being offered from
"Determination of Net Asset Value" in the SAI.

The Portfolio intends to pay redemption proceeds in cash for all interests
redeemed but, under certain conditions, the Portfolio may make payment wholly or
partly in portfolio securities. The Portfolio will select such securities in a
manner it considers equitable, regardless of the composition of the Portfolio's
portfolio at the time of the redemption in-kind. Portfolio securities paid upon
withdrawal or reduction of an interest-holder's investment in the Portfolio will
be valued at their then current market value. The Portfolio Trust has elected to
be governed by the provisions of Rule 18f-1 under the 1940 Act which limits the
Portfolio's obligation to make cash redemption payments to any investor during
any 90-day period to the lesser of $250,000 or 1% of the Portfolio's net asset
value at the beginning of such period. An investor may incur brokerage costs in
converting portfolio securities received upon redemption to cash. The Portfolio
intends that it will not redeem an investor's interest in-kind except in
circumstances in which the particular investor is permitted to redeem in-kind or
in the event that the particular investor completely withdraws its interest in
the Portfolio.

ITEM 19. TAXATION OF THE PORTFOLIO.

The Portfolio Trust incorporates by reference information concerning the
Portfolio's and the Portfolio Trust's tax status from "Taxation" in the SAI.

There are certain tax issues that will be relevant to only certain of the
investors, such as investors who contribute assets rather than cash to the
Portfolio. It is intended that such contributions of assets will not be taxable,
provided certain requirements are met. Such investors are advised to consult
their own tax advisors as to the tax consequences of an investment in the
Portfolio.

Non-U.S. Investors

The following is a discussion of the principal U.S. federal income tax
consequences of an investment in the Portfolio by an entity that is organized or
established under Non-U.S. laws and that is or would be properly classified as a
corporation under the entity classification principles of U.S. tax law (a
"Foreign Investor"). This discussion assumes that, without considering the
effect, if any, of an investment in the Portfolio, the Foreign Investor will not
be engaged in a trade or

B-4
<PAGE>

business in the U.S. and that the Foreign Investor will not have any activities
in or connections with the U.S. other than its investment in the Portfolio. This
discussion also assumes that the Portfolio will be classified as a partnership
for U.S. federal income tax purposes.

The Portfolio intends to operate so that Foreign Investors in the
Portfolio would not be considered to be engaged in a trade or business in the
U.S. solely as a result of investing in the Portfolio, under special U.S.
federal income tax provisions applicable to certain entities the principal
business of which is trading in stocks or securities for their own account.
Consequently, it is anticipated that a Foreign Investor in the Portfolio will
generally not incur any U.S. taxes in respect of the ownership or disposition of
its interest in the Portfolio, including upon the allocation or distribution to
it of the ordinary income and capital gains realized by the Portfolio, with the
exception described in the next sentence. Foreign Investors may be subject to
nonresident alien withholding tax (which would be withheld by the Portfolio or
its agent and paid to U.S. tax authorities) at the rate of 30% (or a reduced
rate if an income tax treaty rate reduction is available) on certain amounts
that are from U.S. sources and are treated as ordinary income allocated to them
by the Portfolio, except to the extent a U.S. withholding tax exemption may be
available. Such an exemption will generally be available principally for (i)
interest income that qualifies as "portfolio interest" under U.S. tax law, (ii)
other interest from certain short-term debt obligations or bank deposits, and
(iii) interest and dividends that are treated as non- U.S. source income under
the Internal Revenue Code of 1986, as amended (the "Code") (e.g., in general,
interest or dividends paid with respect to the Portfolio's investments in stock
or securities of non-U.S. companies or non-U.S. governmental entities, which may
be subject to withholding or other taxes imposed by the countries in which such
issuers are located). Such an exemption will not, however, be available for
dividend income the Portfolio receives with respect to its investments in stock
of U.S. corporations, certain U.S.-source interest that does not qualify as
interest described in clauses (i) or (ii) of the previous sentence, and possibly
certain other income. U.S. withholding taxes could also apply to gains
attributable to any interests held by the Portfolio in U.S. real property other
than interests held solely as a creditor, but the Portfolio anticipates that it
will generally not hold the types of interest in U.S. real property to which
these withholding taxes apply.

If the Portfolio were considered to be engaged in a U.S. trade or business
for U.S. federal income tax purposes, any Foreign Investor in the Portfolio
would also be considered to be engaged in a U.S. trade or business and would be
subject to U.S. federal income tax on its allocable share of any income of the
Portfolio which is considered to be effectively connected with such U.S. trade
or business ("Effectively Connected Income"). The tax on Effectively Connected
Income would be imposed on a net basis at the rates applicable to U.S. taxpayers
generally (and the after-tax amount of such income could also be subject to a
separate branch profits tax at a 30% rate). The Portfolio would be required to
withhold tax from the portion of its

B-5
<PAGE>

Effectively Connected Income which is allocable to Foreign Investors at the
highest rates applicable to U.S. taxpayers (whether or not distributions are
made by the Portfolio to such Foreign Investors during the taxable year). To the
extent the income of the Portfolio constitutes Effectively Connected Income, a
Foreign Investor may also be subject to U.S. federal income tax on some or all
of the gain it recognizes on the disposition of its interest in the Portfolio.
The Portfolio intends to operate in a manner that will not result in any
significant portion of the Portfolio's income being treated as Effectively
Connected Income, although it is possible that the Portfolio could receive some
Effectively Connected Income to the extent, if any, it invests in a partnership
or trust that earns such income or holds certain interests in U.S. real
property.

The U.S. nonresident alien withholding taxes which may be applicable to a
Foreign Investor's allocable share of some of the Portfolio's income might in
some cases be reduced or eliminated under a tax treaty between the U.S. and the
foreign country of which the Foreign Investor is a resident, if that country has
an income tax treaty with the U.S., the Foreign Investor qualifies for benefits
under that treaty, the treaty applies to investments made through partnership
entities like the Portfolio, and any other applicable requirements can be
satisfied. Prospective Foreign Investors should consult their tax advisors
regarding the potential applicability to them of an income tax treaty and the
procedures for qualifying for treaty benefits.

Massachusetts Taxation

A Foreign Investor or U.S. investor that is properly classified as a
corporation under U.S. federal and Massachusetts tax principles (collectively,
an "Investor") might be required to pay Massachusetts corporate excise tax if
the Investor or the Portfolio has sufficient activities in or contacts with the
Commonwealth of Massachusetts ("tax nexus") to be subject to Massachusetts
taxing jurisdiction. The Portfolio intends to conduct its operations so that it
should not have tax nexus with Massachusetts and, consequently, an Investor that
is not otherwise subject to Massachusetts taxation should not become subject to
Massachusetts taxation solely by virtue of investing in the Portfolio. It should
be noted that, under present Massachusetts tax law, an Investor that qualifies
as a RIC under the federal income tax provisions incorporated in Massachusetts
law will not be required to pay any Massachusetts income or Massachusetts
corporate excise or franchise tax even if tax nexus with Massachusetts does
exist as a result of investing in the Portfolio.

ITEM 24. PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH REGISTRANT.

ITEM 25. INDEMNIFICATION.

Reference is hereby made to Article V of the Registrant's Declaration of
Trust, previously filed as an Exhibit.

Under the Registrant's Declaration of Trust, any past or present Trustee
or officer of the Registrant is indemnified to the fullest extent permitted by
law against liability and all expenses reasonably incurred by him in connection
with any action, suit or proceeding to which he may be a party or is otherwise
involved by reason of his being or having been a Trustee or officer of the
Registrant. The Declaration of

C-3
<PAGE>

Trust of the Registrant does not authorize indemnification where it is
determined, in the manner specified in the Declaration, that such Trustee or
officer has not acted in good faith in the reasonable belief that his actions
were in the best interest of the Registrant. Moreover, the Declaration does not
authorize indemnification where such Trustee or officer is liable to the
Registrant or its investors by reason of willful misfeasance, bad faith, gross
negligence or reckless disregard of his or her duties.

Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to Trustees, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that, in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a Trustee, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by any such Trustee, officer or controlling person
against the Registrant in connection with the securities being registered, and
the Commission is still of the same opinion, the Registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification is against public policy as expressed in the Act and will be
governed by the final adjudication of such issue.

ITEM 26. BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER.

Standish, Ayer & Wood, Inc. and Standish International Management Company, L.P.:

The business and other connections of the officers and Directors of
Standish, the investment adviser to all series of the Registrant, other than
Standish Global Fixed Income Portfolio and Standish Diversified Income
