                          LifePath Retirement Portfolio

                              IMPORTANT INFORMATION

Dear Shareholder:

     I am writing to inform you about a reorganization that will affect your
investment in the LifePath 2010 Portfolio ("your fund"). As the target date of
the LifePath 2010 Portfolio approaches in 2010 (as indicated in the LifePath
2010 Portfolio's name), the investment objective, policies and strategies of the
LifePath 2010 Portfolio are converging with the investment objective, policies
and strategies of the LifePath Retirement Portfolio. Barclays Global Investors,
N.A. ("BGI") serves as the administrator of the LifePath 2010 Portfolio and the
LifePath Retirement Portfolio, each a series of Barclays Global Investors Funds
(the "Trust")./1/ Rather than run two separate funds with the same portfolio
allocation, BGI intends to reorganize the LifePath 2010 Portfolio into the
LifePath Retirement Portfolio as provided in an Agreement and Plan of
Reorganization (the "Agreement"), approved by the Board of Trustees of the Trust
(the "Board").

     The enclosed combined information statement and prospectus contains
information about the reorganization of your fund into the LifePath Retirement
Portfolio. As a result of the reorganization, you will receive shares of the
same class in the LifePath Retirement Portfolio equal in value to the value of
your shares of the same class you hold in the LifePath 2010 Portfolio on the
closing date of the reorganization, and you will become a shareholder of the
LifePath Retirement Portfolio, which has an investment objective, policies and
strategies substantially the same as to your fund. We expect that this
reorganization will enable the combined fund to operate more efficiently in the
future.

Why is the Reorganization Taking Place?

     In approving the reorganization, the Board determined that the
reorganization is in the best interests of the shareholders of your fund and the
LifePath Retirement Portfolio and that the interests of each fund's shareholders
will not be diluted as a result of the reorganization. Both funds are part of
the LifePath investment program pursuant to which your fund will have the

- ----------
/1/  The LifePath 2010 Portfolio and the LifePath Retirement Portfolio each
     operate in a master-feeder structure and invest all of their assets in
     corresponding Master Portfolios -- the LifePath 2010 Master Portfolio and
     the LifePath Retirement Portfolio, respectively. Each of these Master
     Portfolios is a series of Master Investment Portfolio and is advised by
     Barclays Global Fund Advisors (the "Adviser"). For simplicity's sake, all
     discussion of investment objectives, strategies and risks of the LifePath
     2010 Portfolio and the LifePath Retirement Portfolio refers also to the
     investment objectives, strategies and risks of their corresponding Master
     Portfolios, unless otherwise indicated. The LifePath 2010 Master Portfolio
     is also being reorganized into the LifePath Retirement Master Portfolio in
     connection with the reorganization of the LifePath 2010 Portfolio into the
     LifePath Retirement Portfolio.




same investment objective, investment policies, strategies and restrictions, and
will be subject to the same investment risks, as the LifePath Retirement
Portfolio as the target date of your fund approaches in 2010 (as indicated in
your fund's name). The portfolio management of a larger combined fund may be
easier than for two separate smaller funds.

No Change in Investment Adviser or Portfolio Managers and No Impact on Fund Fees
and Expenses as a Result of the Reorganization

     The Adviser will continue as the investment adviser of the combined fund
after the reorganization and no change in portfolio managers will result from
the reorganization. In addition, no increase in advisory, administration or
other fee rates will result from the reorganization. Your fund and the LifePath
Retirement Portfolio have the same expense structure, the same types of fees,
the same fee rates and the same or substantially the same annual fund operating
expense ratios.

No Shareholder Action Required as a Result of the Reorganization

     In accordance with the Trust's declaration of trust and applicable Delaware
state and U.S. federal law (including Rule 17a-8 under the Investment Company
Act of 1940 ("Investment Company Act")), the reorganization may be effected
without the approval of shareholders of either fund. Prior to the
reorganization, you may purchase and redeem shares of your fund as usual in
accordance with the procedures described in the enclosed prospectus for the
funds. On or about November 20, 2009, the expected closing date of the
reorganization, your fund will transfer all of its assets and liabilities to the
LifePath Retirement Portfolio, and your shares in the LifePath 2010 Portfolio
will automatically be exchanged for shares of the LifePath Retirement Portfolio.
This will not be a taxable transaction for federal income tax purposes and you
will not recognize gain or loss upon the exchange of your shares as part of this
transaction. The basis of the shares in the LifePath Retirement Portfolio
exchanged for your shares in your fund will be the same as the basis of your
shares in your fund.

     Please note that on June 16, 2009, Barclays PLC, the ultimate parent
company of BGI and the Adviser, accepted a binding offer and entered into an
agreement to sell its interests in the Adviser, BGI and certain affiliated
companies, to BlackRock, Inc. (the "BlackRock Transaction"). The BlackRock
Transaction is subject to certain regulatory approvals, as well as other
conditions to closing. Under the Investment Company Act, completion of the
BlackRock Transaction will cause the automatic termination of the LifePath 2010
Master Portfolio's and the LifePath Retirement Master Portfolio's current
investment advisory agreements with the Adviser. In order for the investment
management of each such Master Portfolio and Portfolio to continue
uninterrupted, the Board of Trustees of the Master Portfolios (the "Master
Portfolios' Board") will be asked to approve a new investment advisory agreement
for each such Master Portfolio. If approved by the Master Portfolios' Board, the
new investment advisory agreement will be submitted for approval by the
investors in such Master Portfolios, including the LifePath 2010 Portfolio and
each LifePath Retirement Portfolio. Each such Portfolio will in turn call a
meeting of its shareholders at which shareholders will vote to instruct the
Portfolio how to vote on the applicable Master Portfolio's new investment
advisory agreement. The BlackRock Transaction and the reorganization are
separate and independent transactions.

                                     SUMMARY

The Reorganization and the Agreement and Plan of Reorganization

     As the target date of the LifePath 2010 Portfolio approaches in 2010 (as
indicated in the LifePath 2010 Portfolio's name), the investment objective,
policies and strategies of the LifePath 2010 Portfolio are converging with the
investment objective, policies and strategies of the LifePath Retirement
Portfolio. Barclays Global Investors, N.A. ("BGI") serves as the administrator
of the LifePath 2010 Portfolio and the LifePath Retirement Portfolio, each a
series of the Trust./2/ Rather than run two separate funds with the same
portfolio allocation, BGI intends to reorganize the LifePath 2010 Portfolio into
the LifePath Retirement Portfolio, as provided in an Agreement and Plan of
Reorganization (the "Agreement").

     The Board of Trustees of the Trust (the "Board") has approved the
Agreement, which provides for the reorganization of your fund into the Acquiring
Fund. The Board concluded that the reorganization is in the best interests of
your fund and that interests of the shareholders of your fund will not be
diluted as a result of the reorganization. Similarly, the Board concluded that
the reorganization is in the best interests of the Acquiring Fund and that
interests of the shareholders of the Acquiring Fund will not be diluted as a
result of the reorganization.

     Under the Agreement, your fund will transfer all of its assets to the
Acquiring Fund in exchange for shares of the Acquiring Fund and the Acquiring
Fund will assume all of the liabilities of your fund. You will receive shares of
the same class in the Acquiring Fund equal in value to the value of your shares
of the same class in your fund on the closing date of the reorganization.
Following the closing of the reorganization, your fund will then be dissolved.
BGI will pay for all of the expenses of the reorganization. Notwithstanding the
foregoing, the Agreement provides that your fund and/or the Acquiring Fund will
bear any expense to the extent necessary under tax law applicable to "regulated
investment companies."

     The implementation of the reorganization is subject to a number of
conditions set forth in the Agreement. Among the significant conditions is the
receipt by your fund of an opinion of counsel to the effect that the
reorganization will not result in income, gain or loss being recognized by your
fund, the Acquiring Fund or the shareholders of your fund for federal income tax
purposes as described further below. This description of the reorganization is
qualified by reference to the full text of the form of the Agreement, which is
attached as Exhibit A.

- ----------
/2/  The LifePath 2010 Portfolio and the LifePath Retirement Portfolio each
     operate in a master-feeder structure and invest all of their assets in
     corresponding Master Portfolios -- the LifePath 2010 Master Portfolio and
     the LifePath Retirement Portfolio, respectively. Each of these Master
     Portfolios is a series of Master Investment Portfolio and is advised by
     Barclays Global Fund Advisors ("BGFA" or the "Adviser"). For simplicity's
     sake, all discussion of investment objectives, strategies and risks of the
     LifePath 2010 Portfolio and the LifePath Retirement Portfolio refers also
     to the investment objectives, strategies and risks of its corresponding
     Master Portfolio, unless otherwise indicated. As discussed below, the
     LifePath 2010 Master Portfolio is also being reorganized into the LifePath
     Retirement Master Portfolio in connection with the reorganization of the
     LifePath 2010 Portfolio into the LifePath Retirement Portfolio.




Comparison of Your Fund to the Acquiring Fund

     The following is a summary of more complete information appearing later in
this Information Statement/Prospectus or incorporated herein by reference. You
should read carefully this entire Information Statement/Prospectus, including
the form of Agreement and Plan of Reorganization attached as Exhibit A. See also
the May 2009 Prospectus. If a row extends across the entire table, the policy

                                                        INVESTMENT INFORMATION

Investment             Each of the Acquiring Fund and the Acquired Fund (each, a "LifePath Portfolio") is a feeder fund that invests
adviser/3/ and         all of its assets in a corresponding master portfolio ("Master Portfolio") that has a substantially identical
portfolio managers     investment objective, strategies and policies as the LifePath Portfolio. The Master Portfolios, in turn,
                       invest in a combination of underlying funds ("Underlying Funds"). BGFA, a registered investment adviser,
                       serves as investment adviser to each Master Portfolio, and also serves as investment adviser to each
                       Underlying Fund, other than the BGIF Institutional Money Market Fund, which invests in a Master Portfolio
                       advised by BGFA. BGFA manages the investing of the Master Portfolios' assets and provides the Master
                       Portfolios with investment guidance and policy direction in connection with daily portfolio management,
                       subject to the supervision of the Master Portfolios' Board of Trustees. For its services to the Master
                       Portfolios, BGFA is entitled to receive an advisory fee at the annual rate of 0.35% of each Master
                       Portfolio's average daily net assets. A discussion regarding the basis for the Master Portfolios' Board of
                       Trustees' approval of the investment advisory agreements with BGFA is available in each LifePath Portfolio's
                       semi-annual report for the six-month period ended June 30, 2009.

                       BGFA receives investment advisory fees from the Underlying Funds for the investment advisory services it
                       provides to those funds. In addition, BGI provides administration services to certain of the Underlying Funds
                       and, for those services, may receive administration fees from those Underlying Funds. BGFA has contractually
                       agreed through April 30, 2011 to waive its advisory fees at the Master Portfolio level in an amount equal to


- ----------
/3/  On June 16, 2009, Barclays PLC, the ultimate parent company of BGI and the
     Adviser, accepted a binding offer and entered into an agreement to sell its
     interests in the Adviser, BGI and certain affiliated companies, to
     BlackRock, Inc. (the "BlackRock Transaction"). The BlackRock Transaction is
     subject to certain regulatory approvals, as well as other conditions to
     closing. Under the Investment Company Act of 1940, as amended, completion
     of the BlackRock Transaction will cause the automatic termination of the
     LifePath 2010 Master Portfolio's and the LifePath Retirement Master
     Portfolio's current investment advisory agreements with the Adviser. In
     order for the investment management of each such Master Portfolio and such
     Portfolio to continue uninterrupted, the Board of Trustees of the Master
     Portfolios (the "Master Portfolios' Board") will be asked to approve a new
     investment advisory agreement for each such Master Portfolio. If approved
     by the Master Portfolios' Board, a new investment advisory agreement will
     be submitted for approval by the investors in such Master Portfolios,
     including the LifePath 2010 Portfolio and each LifePath Retirement
     Portfolio. Each such Portfolio will in turn call a meeting of its
     shareholders at which shareholders will vote to instruct the Portfolio how
     to vote on the applicable Master Portfolio's new investment advisory
     agreement. The BlackRock Transaction and the reorganization are separate
     and independent transactions.

Investment objective   Each fund seeks to maximize return consistent with the quantitatively measured risk that investors on average
and restrictions       may be willing to accept given their investment time horizon. Each fund's investment objective may be changed
                       by the Board without shareholder approval. Each fund has the identical fundamental and non-fundamental
                       investment restrictions

                       Your fund is managed for investors planning to retire   The Acquiring Fund is managed for investors seeking

                       investment) approximately in the year 2010.

                       As indicated in the table below, as the target date
                       of the LifePath 2010 Portfolio approaches in 2010,
                       the investment objective, policies and strategies of
                       the LifePath 2010 Portfolio are converging with the
                       investment objective, policies and strategies of the
                       LifePath Retirement Portfolio.

                       The Adviser has reported that (1) as of October 2009, your fund and the Acquiring Fund will both have the
                       same investment objective, strategies, policies and restrictions and the most conservative allocation within
                       the LifePath strategy and (2) at the closing of the reorganization, their portfolios of Underlying Funds are
                       expected to be identical.

Primary investments    Each fund invests all of its assets in a corresponding Master Portfolio which allocates and re-allocates its
and strategies         assets among Underlying Funds. The Underlying Funds invest in a mix of equity securities, bonds and money
                       market instruments. Certain Underlying Funds invest in real estate investment trusts, foreign securities,
                       emerging markets, below investment grade bonds and derivatives, which are subject to additional risks.

                       Your fund's allocation of assets among Underlying       The Acquiring Fund is in its most conservative phase
                       Funds that invest primarily in equity securities and    and therefore its allocation generally does not

                       become more conservative over time and to have lower
                       expected returns as the stated time horizon of 2010
                       approaches.

                       Allocation: As of November 2009 the allocation of your fund is expected to be the same as the allocation of
                       the Acquiring Fund.

                       Each Fund is expected to have approximately 38% of its assets in Underlying Funds that invest primarily in
                       equity securities, 62% of its assets in Underlying Funds that invest primarily in bonds and the remainder in
                       Underlying Funds that invest primarily in money market instruments.

Other investments      In addition to investing in Underlying Funds, each fund may borrow, lend its securities to brokers, dealers
                       and financial institutions, and may invest the collateral in short-term instruments either directly or
                       through one or more joint accounts or money market funds.

Benchmarks             The funds use custom benchmarks that are hypothetical representations of the performance of the applicable
                       LifePath Portfolio's asset classes according to their weightings as of the most recent quarter end. The
                       weightings

No sales charges;      The sales charge and Rule 12b-1 fee structure are the same for each fund:
Rule 12b-1 fees for
Class R Shares              .  Shares of each fund are purchased and sold without paying a sales charge.

                            .  Class I and Class S shares are not subject to Rule 12b-1 fees.

                            .  Rule 12b-1 fees are paid out of the assets of Class R shares of each fund at an annual rate of 0.25%
                               of the average daily net assets of the Class R shares.

                            .  Holders of Class R Shares may be charged additional fees by the shareholder servicing agent.

Buying shares          The procedures for buying shares of the Acquiring Fund are identical to those of your fund. You may buy
                       shares

                            .  through an employer-sponsored or individual retirement savings plan,

                            .  through a custodian or shareholder servicing agent of the funds,

                            .  through an account with State Street Bank and Trust ("State Street"), the funds' transfer agent and
                               custodian (Class R Shares only), or

                            .  directly from the funds (Class I Shares only).

                       You can purchase shares at their net asset value, next determined after receipt of the purchase order.
                       Purchases generally must be made in U.S. dollars.

Minimum initial        The minimum initial investment for both funds are the same:
investment
                            .  Classes R and S have no minimum initial investment.

                            .  Class I has no minimum initial investment (except a $1 million initial investment that applies only
                               to direct investment).

Selling shares         The procedures for selling shares of the Acquiring Fund are identical to those of your fund. You may sell
                       shares on any business day at their net asset value, next determined after receipt of the order.

Net asset value        The procedure for calculating net asset value is the same for both funds:

                               For each fund class, net asset value is calculated by deducting all of its liabilities (including
                               accrued expenses) from the total value of its assets (including securities held by the fund plus any
                               cash or other assets, including interest and dividends accrued but not yet received) and dividing the
                               result by the number of shares outstanding, and generally rounded to the nearest cent. Each fund
                               calculates a net asset value for its shares at the close of regular trading on the New York Stock
                               Exchange (generally, 4:00 p.m. Eastern Time) on any business day.

                                                                 TAX

Federal income tax     For federal income tax purposes, the reorganization will not result in income, gain or loss being recognized
consequences           by your fund, the Acquiring Fund or the shareholders of your fund. For further information see "Federal

strategies, please refer to the comparison chart above.

                                      -4-




Comparison of Principal Risks of Investing in the Funds

     As your fund's investment horizon date (2010) approaches, its investment
objective, policies and strategies will become substantially identical to those
of the Acquiring Fund. Accordingly, the funds are generally subject to the same
types of principal risks./4/ These principal risks are:

     .    Equity Securities Market Risk: The price of the equity securities in
          which the Underlying Funds invest may fluctuate or fall in response to
          economic events or trends.

     .    Bond Investment Risks: Risks associated with investment in bonds
          include (a) interest rate risk, which means that the prices of bonds
          in which the Underlying Funds invest may fall because of a rise in
          interest rates, and credit risk, which is the risk that the price of
          an individual bond may fall with the decline in an issuer's real or
          apparent ability to meet its financial obligations; (b) extension
          risk, which is the risk that borrowers may extend the prepayment of
          their mortgages or loans for longer periods than expected, thereby
          affecting the security's average life and, potentially, its yield; and
          (c) prepayment risk, which is the risk that borrowers may prepay their
          mortgages or loans faster than expected, thereby affecting the
          security's average life and, potentially, its yield. The risk of
          default and price volatility of high yield securities is greater than
          the risk usually associated with higher-rated securities. The funds'
          yields may decline during times of falling interest rates.

     .    Investments in Foreign Securities: Investments in foreign securities
          by the Underlying Funds are subject to certain special risks and
          considerations, including potentially less liquidity and greater price
          volatility than investments in securities traded in U.S. markets.
          These risks are greater for investments in foreign securities issued
          by companies or sovereign entities in emerging market countries.

     .    Passive Investment Risk: Because the Adviser does not select
          individual companies in the underlying indexes for certain Underlying
          Funds, those Underlying Funds may hold stocks in companies that
          present risks that an adviser researching individual stocks might seek
          to avoid.

     .    Security Selection Risk: In the case of the Underlying Funds where
          BGFA does select securities based on its analysis, these funds are
          subject to the risk that security selection will contribute to
          underperformance.

     .    Concentration Risk: The risk that an Underlying Fund that concentrates
          in a single industry or group of industries may be more susceptible to
          any single economic, market, political or regulatory occurrence in
          that industry or group of industries.

     .    Real Estate Investment Risk: The risk that investment in securities
          exposed to real estate carries many of the same risks associated with
          the direct ownership of real estate.

     .    Derivatives: Investments in derivatives by certain Underlying Funds
          are subject to special risks and considerations. Derivatives are
          financial instruments whose values

- ----------
/4/  Historically, as a result of differences in the funds' time horizons and
     the resulting differences in their Master Portfolios' investment allocation
     between Underlying Funds that invest in equity securities and bonds, the
     Acquired Fund may have had greater exposure to certain risks described
     below than the Acquiring Fund. However, those differences are of limited
     relevance as the Acquired Fund will reach its target date and Master
     Portfolios will have the same portfolio allocation in November 2009.

                                      -5-




          are derived, at least in part, from the prices of other securities or
          specified assets, indexes or rates.

     .    Market Trading Risk: The risk certain Underlying Funds face due to
          their shares being listed and traded on securities exchanges
          (including potential halts in trading or a fluctuation in trading
          price in accordance with changes in net asset value), and tracking
          error risk, in that the return of an Underlying Fund that seeks to
          track an index may deviate from the return of such index.

     The funds cannot eliminate risk or assure achievement of their investment
objectives and you may lose money by investing in the funds.

The Funds' Fees and Expenses

     The Acquiring Fund and the Acquired Fund have the same expense structure,
the same fees and fee rates and the same or substantially the same annual fund
operating expense ratios. More detailed information regarding expenses appears
in Exhibit B.

Performance

     Historically, as contemplated by the LifePath strategy, the performance of
the Acquiring Fund and the Acquired Fund have differed due to their different
time horizons and portfolio allocations. However, the differences are of limited
relevance since the Acquired Fund will reach its target date in November 2009,
and thereafter the Acquiring Fund and the Acquired Fund would have the most
conservative allocation of the LifePath strategy and the same portfolio
allocation. For further information regarding historical performance, see
Exhibit C.

                               THE REORGANIZATION

Agreement and Plan of Reorganization

     The Board approved the Agreement regarding the reorganization, a copy of
which is attached to this Information Statement/Prospectus as Exhibit A. The
description of the Agreement contained herein is qualified in its entirety by
the attached copy.

The Reorganization

     The Agreement provides for the reorganization on the following terms:

     .    The reorganization is scheduled to occur on the close of business on
          November 20, 2009, but may occur on a later date as the Board
          determines. Your fund will transfer all of its assets to the Acquiring
          Fund, and the Acquiring Fund will assume all of your fund's
          liabilities. This will result in the addition of your fund's assets to
          the Acquiring Fund's portfolio. The net asset value of both funds will
          be computed as of the close of regular trading on the New York Stock
          Exchange on the reorganization date.

     .    The Acquiring Fund will issue shares to your fund with a value equal
          to the net assets attributable to your fund's shares. As part of the
          liquidation of your fund, these shares will immediately be distributed
          to shareholders of record of your fund so that

                                      -6-




          you will receive shares of the same class in the Acquiring Fund with a
          value equal to the value of your shares of the same class in your fund
          on the reorganization date. As a result, shareholders of your fund
          will become shareholders of the Acquiring Fund.

     .    After the shares are issued, the existence of your fund will be
          terminated.

Since each fund is a feeder fund that invests all of its assets in a Master
Portfolio, there are other aspects of the reorganization that are not covered in
the Agreement or this Information Statement/Prospectus because they do not
relate to your fund or the Acquiring Fund directly. Prior to the reorganization
of your fund into the Acquiring Fund, the LifePath 2010 Master Portfolio and the
LifePath Retirement Master Portfolio will be combined. That combination is not
governed by the Agreement or this Information Statement/Prospectus.

Reasons for the Reorganization

     At a meeting held on May 20, 2009, the Board approved the Agreement on
behalf of your fund. The Board also determined that the reorganization is in the
best interests of your fund and that the interests of shareholders of your fund
will not be diluted as a result of the reorganization. The Board believes that
the reorganization will be advantageous to the shareholders of your fund for
several reasons. The Board considered the following matters, among others, in
approving the reorganization:

     FIRST, both funds are part of the LifePath investment program pursuant to
which the combined fund will have the same investment objective, investment
policies, strategies and restrictions as your fund, and will be subject to the
same investment risks.

     SECOND, there will be no change in the investment adviser or in the persons
managing the portfolios,/5/ and BGFA advised the Board that it does not
anticipate that the reorganization will result in any decline in the level of
investment advisory services from that historically provided to the funds.

     THIRD, no increase in advisory, administration or other fees, as a
percentage of average daily net assets, will occur as a result of the
reorganization, nor will there be any change in the contractual terms of the
existing investment advisory agreement with BGFA or other service agreements
with BGI as a result of the reorganization.

     FOURTH, your fund and the Acquiring Fund have the same expense structure,
the same fees and fee rates and the same or substantially the same annual fund
operating expense ratio.

     FIFTH, in addition to having the same investment adviser and administrator,
your fund and the Acquiring Fund have the same service providers, such as the
custodian, transfer agent, subadministrator, principal underwriter, auditors and
counsel.

     SIXTH, for federal income tax purposes, the reorganization will not result
in income, gain, or loss being recognized by your fund, the Acquiring Fund or
the shareholders of your fund (as further discussed below).

- ----------
/5/  See footnote 3.

                                      -7-




     SEVENTH, the shareholder services and privileges available to the Acquiring
Fund are the same as those available to your fund.

     EIGHTH, the funds use the same methodology for valuing their assets and
that each shareholder of your fund will receive shares of the same class of the
Acquiring Fund with an aggregate net asset value identical to that of the shares
of the same class of your fund that such shareholder held immediately prior to
the reorganization. As a result, the existing interests of the shareholders
would not be diluted as a result of the reorganization.

     NINTH, because it can be more efficient to run a single larger fund than
smaller separate funds, over time lower expenses may result from the combined
funds' larger asset and income base./6/

     The Board considered that BGI will pay all of the expenses of the funds in
connection with the reorganization, including expenses associated with the
preparation, printing and mailing of any shareholder communications, including
this Information Statement/Prospectus, and any filings with the SEC and other
governmental agencies in connection with the reorganization (except that the
Acquired Fund and the Acquiring Fund will bear any expense to the extent
necessary under tax law applicable to "regulated investment companies"). It is
expected that the reorganization will not result in any additional expenses
being incurred by the shareholders of the funds either directly as a result of
effectuating the reorganization or indirectly over time.

     The Board further considered that the funds' shareholders approved in 2007
as amendment to the Trust's Declaration of Trust to allow the Board to authorize
a LifePath series' merger or consolidation with, or sale of assets to, another
LifePath series without shareholder approval (unless shareholder approval is
required by the Investment Company Act). The Board considered the reason for
this amendment was, among other things, to permit the Board to approve a merger
or reorganization of one LifePath series whose target date was approaching into
another LifePath series that had already reached its target date, without the
necessity of a shareholder vote and this reason was explained in the Proxy
Statement to shareholders relating to such amendment.

     The Board, to the extent it deemed relevant, also considered the funds'
investment performance records in light of the overall LifePath strategy and the
funds' different time horizons.

     The Board considered that the funds are series of BGIF. As such, there will
be no change in the governance of the funds, including without limitation the
composition of the Boards, as a result of the reorganization. In addition, there
will be no change in the compliance program of the Acquiring Fund, including
without limitation the person serving as the chief compliance officer, as a
result of the reorganization.

- ----------
/6/  The Board noted that since the LifePath Retirement Master Portfolio pays
     advisory fees to BGFA and the Acquiring Fund pays administration fees to
     BGI, out of which BGI pays virtually all of the Acquiring Funds' other
     expenses, any such economies and savings would accrue to BGFA and BGI under
     the current expense structure.

                                      -8-




     In addition, the Board considered possible alternatives to the
reorganization, including maintaining the status quo. The Board, however,
determined that, given the Funds' LifePath strategy, the opportunity presented
by the reorganization and the factors in favor of the reorganization made the
reorganization more compelling than these alternatives. For the reasons stated
above and other factors considered by the Board, the Board determined that the
reorganization is in the best interests of your fund and its shareholders.

Tax Status of the Reorganization

     The reorganization is intended to result in no income, gain or loss for
federal income tax purposes to the Acquiring Fund, your fund or the shareholders
of your fund. Consummation of the reorganization is subject to the condition
that your fund and the Acquiring Fund receive an opinion from Wilmer Cutler
Pickering Hale and Dorr LLP, counsel to the Trust, substantially to the effect
that

     .    the reorganization will be a "reorganization" within the meaning of
          section 368(a) of the Internal Revenue Code of 1986;

     .    the reorganization will not result in taxable income, gain or loss to
          any fund or to its shareholders;

     .    the basis of the Acquiring Fund shares received by you in the
          Reorganization will be the same as the basis of your shares of the
          Acquired Fund surrendered in exchange; and

     .    the tax holding period of the Acquiring Fund shares you receive will
          include the tax holding period of the shares of the Acquired Fund
          surrendered in the exchange, provided that the shares of the Acquired
          Fund were held as capital assets on the date of the exchange.

In rendering such opinion, counsel will rely upon, among other things,
reasonable assumptions as well as representations of the Acquiring Fund, your
fund, the Master Portfolios, and certain Underlying Funds.

     No ruling has been or will be received from the Internal Revenue Service
("IRS") in connection with the reorganization. An opinion of counsel is not
binding on the IRS or a court, and no assurance can be given that the IRS would
not assert, or a court would not sustain, a contrary position.

     The foregoing discussion does not address certain classes of taxpayers who
are subject to special circumstances, such as shareholders who are not citizens
or residents of the United States, insurance companies, tax-exempt
organizations, financial institutions, dealers in securities or foreign
currencies, or persons who hold their shares as part of a straddle or conversion
transaction.

     You should consult your own advisor for the particular tax consequences to
you of the reorganization, including the applicability of any state, local or
foreign tax laws.

                                      -9-




Additional Terms of the Agreement and Plan of Reorganization

     Conditions to Closing the Reorganization. The obligation of the Acquiring
Fund to consummate the reorganization is subject to the satisfaction of
customary conditions, including your fund's performance of its obligations under
the Agreement, the receipt of certain documents and financial statements from
your fund and the receipt of all consents, orders and permits necessary to
consummate the reorganization (see Agreement, section 6).

     The obligation of your fund to consummate the reorganization is subject to
the satisfaction of customary conditions, including the performance by the
Acquiring Fund of its obligations under the Agreement, and the receipt of all
consents, orders and permits necessary to consummate the reorganization (see
Agreement, section 7).

     The funds' obligations are also subject to the receipt of a favorable
opinion of Wilmer Cutler Pickering Hale and Dorr LLP as to the federal income
tax consequences of the reorganization (see Agreement, section 8).

     Termination of Agreement. The Board may terminate the Agreement at any time
before the reorganization date if the Board believes that proceeding with the
reorganization would no longer be advisable (see Agreement, section 11).

                                 CAPITALIZATION

     The following table sets forth the capitalization of each fund as of June
30, 2009, and the pro forma combined capitalization of both funds as if the
reorganization had occurred on that date. When the reorganization is
consummated, the actual exchange ratios on the reorganization date may vary from
the exchange ratios indicated. This is due to changes in the market value of the
portfolio securities of both funds between June 30, 2009, and the reorganization
date, changes in the amount of undistributed net investment income and net
realized capital gains of both funds during that period resulting from income
and distributions, and changes in the accrued liabilities of both funds during
the same period.

     It is impossible to predict how many shares of the Acquiring Fund will
actually be received and distributed by your fund on the closing date of the
reorganization. The table should not be relied upon to determine the amount of
the Acquiring Fund's shares that will actually be received and distributed.

                      BOARD'S EVALUATION AND RECOMMENDATION

     For the reasons described above, the Board, including a majority of the
trustees who are not "interested persons" of the Trust within the meaning of the
Investment Company Act (the "Independent Trustees"), approved the
reorganization. In particular, the Board determined that the reorganization is
in the best interests of your fund and that the interests of your fund's
shareholders will not be diluted as a result of the reorganization. Similarly,
the Board, including the Independent Trustees, approved the reorganization on
behalf of the Acquiring Fund. The Board also determined that the reorganization
is in the best interests of the Acquiring Fund and that the interests of the
Acquiring Fund's shareholders will not be diluted as a result of the
reorganization.

                                                                       Exhibit A

                  FORM OF AGREEMENT AND PLAN OF REORGANIZATION

     THIS AGREEMENT AND PLAN OF REORGANIZATION ("Agreement") is made as of the
__ day of ________, 2009, by and between Barclays Global Investors Funds, a
Delaware statutory trust ("Trust"), on behalf of its series, LifePath Retirement
Portfolio ("Acquiring Fund"), with its principal place of business at 400 Howard
Street, San Francisco, California 94105, and the Trust on behalf of its series,
LifePath 2010 Portfolio ("Acquired Fund"). The Acquiring Fund and the Acquired
Fund are sometimes referred to collectively herein as "Funds" and individually
as "Fund."

     This Agreement is intended to be and is adopted as a plan of a
"reorganization" as defined in Section 368(a)(1)(D) of the United States
Internal Revenue Code of 1986, as amended ("Code"), and the Treasury Regulations
thereunder. The reorganization ("Reorganization") will consist of (1) the
transfer of all of the assets of the Acquired Fund to the Acquiring Fund solely
in exchange for (A) the issuance of shares of beneficial interest of the
Acquiring Fund that correspond to the shares of the Acquired Fund equal to the
net asset value represented by such shares (collectively, "Acquiring Fund
Shares" and each, an "Acquiring Fund Share") to the Acquired Fund, and (B) the
assumption by the Acquiring Fund of all of the liabilities of the Acquired Fund
on the closing date of the Reorganization ("Closing Date") ("Assumed
Liabilities"), and (2) the distribution by the Acquired Fund, on or promptly
after the Closing Date as provided herein, of the Acquiring Fund Shares to the
shareholders of the Acquired Fund in liquidation and dissolution of the Acquired
Fund, all upon the terms and conditions hereinafter set forth in this Agreement.

     WHEREAS, the Acquiring Fund and the Acquired Fund are each series of the
Trust, a registered investment company classified as a management company of the
open-end type, and the Acquired Fund owns securities that are assets of the
character in which the Acquiring Fund is permitted to invest;

     WHEREAS, the Acquiring Fund is authorized to issue shares of beneficial
interest;

     WHEREAS, the Board of Trustees of the Trust ("Board") has determined that
the exchange of all of the assets of the Acquired Fund for Acquiring Fund Shares
and the assumption of the Assumed Liabilities of the Acquired Fund by the
Acquiring Fund are in the best interests of the Acquiring Fund shareholders and
that the interests of the existing shareholders of the Acquiring Fund will not
be diluted as a result of the Reorganization; and

     WHEREAS, the Board has determined that the exchange of all of the assets of
the Acquired Fund for Acquiring Fund Shares and the assumption of the Assumed
Liabilities of the Acquired Fund by the Acquiring Fund are in the best interests
of the Acquired Fund shareholders and that the interests of the existing
shareholders of the Acquired Fund will not be diluted as a result of the
Reorganization.

                                       A-1




     NOW, THEREFORE, in consideration of the covenants and agreements
hereinafter set forth, the parties hereto covenant and agree as follows:

1.   TRANSFER OF ASSETS OF THE ACQUIRED FUND IN EXCHANGE FOR THE ACQUIRING FUND
     SHARES AND ASSUMPTION OF THE ASSUMED LIABILITIES; LIQUIDATION AND
     TERMINATION OF THE ACQUIRED FUND.

     1.1 Transfer of Assets by Acquired Fund; Issuance of Shares and Assumption
of Liabilities by Acquiring Fund. Subject to the requisite approvals, the terms
and conditions herein set forth and on the basis of the representations and
warranties contained herein, the Acquired Fund will sell, assign, convey,
transfer and deliver all of its property and assets as set forth in Section 1.2
("Acquired Assets") to the Acquiring Fund free and clear of all liens and
encumbrances (other than those, if any, arising under the Securities Act of
1933, as amended ("Securities Act"), liens for Taxes (as defined below) not yet
due, and, as disclosed to the Trust in accordance with Section 3.2 hereof,
contractual restrictions, if any, on the transfer of the Acquired Assets), and
the Acquiring Fund agrees in exchange therefor: (i) to issue to the Acquired
Fund the number of Acquiring Fund Shares, including fractional Acquiring Fund
Shares, of the applicable class with an aggregate net asset value ("NAV") equal
to the NAV of the Acquired Fund's shares of the corresponding class, as
determined in the manner set forth in Article 2; and (ii) to assume all of the
liabilities (whether absolute or contingent, known or unknown) of the Acquired
Fund ("Assumed Liabilities"). Such transactions shall take place at the Closing
(as defined in Section 3.1 below).

     1.2 Assets to be Acquired; Investments by Acquired Fund Pending Closing.

          (a) The Acquired Assets shall consist of all of the Acquired Fund's
assets and property as of the Valuation Time (as defined in Article 2),
including, without limitation, all portfolio securities and instruments,
dividends, receivables (including dividends, interest and other receivables),
cash, cash equivalents, deferred or prepaid expenses, goodwill, rights and
choses in action of the Acquired Fund or the Trust in respect of the Acquired
Fund, all other tangible and intangible property owned by the Acquired Fund,
originals or copies of all books and records of the Acquired Fund, and all other
assets of the Acquired Fund. The Acquiring Fund shall also be entitled to
receive copies of all records that the Acquired Fund is required to maintain
under the Investment Company Act of 1940, as amended ("Investment Company Act"),
and the rules of the Securities and Exchange Commission ("Commission")
thereunder.

          (b) The Acquired Fund has provided the Acquiring Fund with a list of
all of the Acquired Fund's securities and other assets as of the date of
execution of this Agreement, specifically describing all contractual
restrictions, if any, on the transfer of such assets. The Acquired Fund reserves
the right to sell any of such securities or other assets before the Closing Date
(except to the extent sales may be limited by representations of the Acquired
Fund contained herein and made in connection with the issuance of the tax
opinion provided for in Section 8.4 hereof). The Acquired Fund agrees not to
acquire any portfolio security or other asset that is not an eligible investment
for, or that would violate any investment policy or restriction of, the
Acquiring Fund. For avoidance of doubt, reference is hereby made to Section 5.1
of this Agreement pursuant to which the Acquired Fund agrees to operate its
business

                                       A-2




in the ordinary course and to comply in all material respects with all
applicable laws, rules and regulations between the date hereof and the Closing
Date.

     1.3 Assumed Liabilities. The Acquired Fund will endeavor to discharge all
of its known liabilities and obligations that are or will become due prior to
the Valuation Time. Notwithstanding the foregoing, any liabilities not so
discharged as of the Valuation Time shall be Assumed Liabilities, which shall
include all of the Acquired Fund's liabilities, debts, obligations, and duties
of whatever kind or nature, whether absolute, accrued, contingent, or otherwise,
whether known or unknown, whether or not arising in the ordinary course of
business, whether or not determinable at the Closing Date, and whether or not
specifically referred to in this Agreement. The Acquiring Fund shall assume the
Assumed Liabilities at the Closing.

     1.4 Liquidation of Acquired Fund; Distribution of Acquiring Fund Shares. On
the Closing Date or as soon thereafter as is practicable, the Acquired Fund
shall distribute pro rata to its shareholders of record, determined as of the
close of regular trading on the New York Stock Exchange ("NYSE") on the Closing
Date ("Acquired Fund Shareholders"), the Acquiring Fund Shares received by the
Acquired Fund pursuant to Section 1.1 hereof. Each Acquired Fund Shareholder
shall receive the number of Acquiring Fund Shares of the class corresponding to
the shares of beneficial interest of the same class in the Acquired Fund
("Acquired Fund Shares") held by such Acquired Fund Shareholder that have an
aggregate NAV equal to the aggregate NAV of the Acquired Fund Shares held of
record by such Acquired Fund Shareholder on the Closing Date. Such distribution
will be accomplished by the Trust instructing its transfer agent ("Transfer
Agent") to transfer the Acquiring Fund Shares then credited to the account of
the Acquired Fund on the books of the Acquiring Fund to open accounts on the
share records of the Acquiring Fund established and maintained by the Transfer
Agent in the names of the Acquired Fund Shareholders and representing the
respective pro rata number of the Acquiring Fund Shares due the Acquired Fund
Shareholders. The Transfer Agent shall retain evidence of such distribution. All
issued and outstanding Acquired Fund Shares will simultaneously be cancelled on
the books of the Acquired Fund, and as soon as practicable thereafter, the Trust
shall terminate the existence of the Acquired Fund as a series of the Trust
under the laws of the State of Delaware and in accordance with the Trust's
Agreement and Declaration of Trust ("Trust Instrument") and By-Laws. The
Acquiring Fund shall not issue certificates representing the Acquiring Fund
Shares in connection with such exchange.

     1.5 Cancellation of Acquired Fund Share Certificates. Ownership of
Acquiring Fund Shares will be shown on the books of the Transfer Agent. Any
certificates representing ownership of Acquired Fund Shares that remain
outstanding on the Closing Date shall be deemed to be cancelled and shall no
longer evidence ownership of Acquired Fund Shares.

     1.6 Transfer Taxes. Any transfer taxes payable upon issuance of Acquiring
Fund Shares in a name other than the registered holder of the Acquired Fund
Shares on the books of the Acquired Fund as of that time shall, as a condition
of such issuance and transfer, be paid by the person to whom such Acquiring Fund
Shares are to be issued and transferred.

     1.7 Acquired Fund Reporting Responsibility. Any reporting responsibility of
the Trust with respect to the Acquired Fund for taxable periods ending on or
before the Closing Date, including, but not limited to, the responsibility for
filing of regulatory reports, Tax Returns

                                       A-3




(as defined in Section 4.1(j)(O) below), or other documents with the Commission,
any state securities commissions, and any federal, state or local tax
authorities or any other relevant regulatory authority, is and shall remain the
responsibility of the Trust on behalf of the Acquired Fund.

2.   VALUATION

     The NAV of the Acquiring Fund Shares and the NAV of the Acquired Fund
shall, in each case, be determined as of the close of regular trading on the
NYSE, and after the declaration of any dividends by the Acquired Fund, on the
Closing Date (such time and date being hereinafter called the "Valuation Time"),
computed using the valuation procedures previously approved by the Board. All
computations of value shall be made by the fund accountant for the Trust
("Administrator"). The Acquired Fund shall cause the Administrator to deliver a
copy of its valuation report to the Acquiring Fund at the Closing.

3.   CLOSING AND CLOSING DATE

     3.1 Closing Date and Place. The Closing Date shall be November 20, 2009, or
such later date as the parties may agree to in writing. All acts necessary to
consummate the Reorganization ("Closing") shall be deemed to take place
simultaneously as of the close of business on the Closing Date unless otherwise
agreed to by the parties. The close of business on the Closing Date shall be as
of 4:00 p.m. (Eastern time) or such later time on that date as the Acquired
Fund's NAV is calculated in accordance with Article 2 and after the declaration
of any dividends by the Acquired Fund. The Closing shall be held at the offices
of the Trust, or at such other place as the parties may agree.

     3.2 Delivery of Acquired Assets by Acquired Fund. State Street Bank & Trust
Company ("SSB&T") serves as custodian and record holder for each Fund, and in
that capacity for the Acquiring Fund ("Acquiring Fund Custodian"), SSB&T shall
examine the portfolio securities, if any, that are held other than in book-entry
form in the name of SSB&T as custodian and record holder for the Acquired Fund
("Acquired Fund Custodian") no later than three (3) business days preceding the
Closing Date, together with a description of all contractual restrictions on the
transfer of the Acquired Assets. Such portfolio securities shall be delivered by
the Acquired Fund to the Acquiring Fund Custodian for the account of the
Acquiring Fund on the Closing Date, duly endorsed in proper form for transfer,
in such condition as to constitute good delivery thereof in accordance with the
custom of brokers, and shall be accompanied by all necessary federal and state
stock transfer stamps or a check or other appropriate means for the appropriate
purchase price thereof. Portfolio securities held of record by the Acquired Fund
Custodian in book-entry form on behalf of the Acquired Fund shall be delivered
by the Acquired Fund Custodian through the Depository Trust Company to the
Acquiring Fund Custodian and by the Acquiring Fund Custodian recording the
beneficial ownership thereof by the Acquiring Fund on the Acquiring Fund
Custodian's records in accordance with the customary practices of the Acquiring
Fund Custodian and of each securities depository, as defined by Rule 17f-4 under
the Investment Company Act. Any cash balances maintained by the Acquired Fund
shall be delivered by the Acquired Fund Custodian and the Acquiring Fund
Custodian crediting such amounts to the account of the Acquiring Fund from the
account of the Acquired Fund.

                                       A-4




     3.3 Custodian Certificate with respect to Delivery of Acquired Assets. The
Trust shall direct the Acquired Fund Custodian to deliver at the Closing a
certificate of an authorized officer stating that: (a) the Acquired Assets have
been delivered in proper form to the Acquiring Fund on the Closing Date; and (b)
all necessary transfer Taxes including all applicable federal and state stock
transfer stamps, if any, have been paid, or provision for payment has been made
in conjunction with the delivery of portfolio securities as part of the Acquired
Assets.

     3.4 Trading Restriction on Scheduled Closing Date. If on the Closing Date
(a) the NYSE is closed to trading or trading thereon shall be restricted or (b)
trading or the reporting of trading on such exchange or elsewhere is disrupted
so that accurate appraisal of the NAV of the Acquiring Fund Shares or the
Acquired Fund pursuant to Article 2 is impracticable, the Closing Date shall be
postponed until the first business day after the day when trading shall have
been fully resumed and reporting shall have been restored.

     3.5 Acquired Fund Shareholder List. The Acquired Fund shall deliver at the
Closing a list of the names, addresses, federal taxpayer identification numbers
and backup withholding and nonresident alien withholding status and certificates
of the Acquired Fund Shareholders and the number and percentage ownership of
outstanding Acquired Fund Shares owned by each Acquired Fund Shareholder as of
the Valuation Time, certified by the President or the Secretary of the Trust and
its Treasurer, Secretary or other authorized officer ("Shareholder List") as
being an accurate record of the information (a) provided by the Acquired Fund
Shareholders, (b) provided by the Acquired Fund's transfer agent, or (c) derived
from the Trust's records by such officers or one of the Trust's service
providers.

     3.6 Acquiring Fund Shares Credited to Acquired Fund. The Acquiring Fund
shall issue and deliver to the Acquired Fund a confirmation evidencing the
Acquiring Fund Shares to be credited on the Closing Date, or provide evidence
satisfactory to the Acquired Fund that such Acquiring Fund Shares have been
credited to the Acquired Fund's account on the books of the Acquiring Fund. At
the Closing, each party shall deliver to the other such bills of sale, checks,
assignments, stock certificates, receipts or other documents as such other party
or its counsel may reasonably request.

4.   REPRESENTATIONS AND WARRANTIES

     4.1 Representations and Warranties by Acquired Fund. Except as set forth on
Schedule 4.1 hereto, the Trust, on behalf of the Acquired Fund, represents,
warrants and covenants to the Acquiring Fund, which representations, warranties
and covenants are true and correct on the date hereof, as follows:

          (a) The Acquired Fund is a series of the Trust. The Trust is a
statutory trust duly organized, validly existing and in good standing under the
laws of the State of Delaware. The Trust has the power to own all of its
properties and assets and to perform its obligations under this Agreement. The
Acquired Fund is not required to qualify to do business in any jurisdiction in
which it is not so qualified or where failure to qualify would subject it to any
material liability or disability. Each of the Trust and the Acquired Fund has
all necessary federal, state and local authorizations to own all of its
properties and assets and to carry on its business as now being conducted;

                                       A-5




          (b) The Trust is a series registered investment company classified as
a management company of the open-end type, and its registration with the
Commission as an investment company under the Investment Company Act is in full
force and effect;

          (c) The Trust is not in violation of, and the execution and delivery
of this Agreement and the performance of its obligations under this Agreement
will not result in (i) a violation of, any provision of the Trust Instrument or
Bylaws or any material agreement, indenture, instrument, contract, lease or
other undertaking with respect to the Acquired Fund to which the Trust is a
party or by which the Acquired Fund or any of its assets are bound, or (ii) the
acceleration of any obligation, or the imposition of any penalty under any
agreement, indenture, instrument, contract, lease, judgment or decree to which
the Trust, on behalf of the Acquired Fund, is a party or by which it is bound;

          (d) No consent, approval, authorization, or order of any court or
governmental authority is required for the consummation by the Acquired Fund of
the transactions contemplated herein, except such as may be required under the
Securities Act, the Securities Exchange Act of 1934, as amended ("Exchange
Act"), the Investment Company Act, and state securities laws;

          (e) No litigation or administrative proceeding or investigation of or
before any court or governmental body is currently pending or to its knowledge
threatened against the Acquired Fund or any of the Acquired Fund's properties or
assets. The Acquired Fund knows of no facts that might form the basis for the
institution of such proceedings. Neither the Trust nor the Acquired Fund is a
party to or subject to the provisions of any order, decree or judgment of any
court or governmental body which materially and adversely affects the Acquired
Fund's business or its ability to consummate the transactions contemplated
herein or would be binding upon the Acquiring Fund as the successor to the
Acquired Fund;

          (f) All material contracts or other commitments of the Acquired Fund
(other than this Agreement, contracts listed in Schedule 4.1 and certain
investment contracts, including options, futures and forward contracts) will
terminate without liability to the Acquired Fund on or prior to the Closing

agreement;

          (g) The Statement of Assets and Liabilities of the Acquiring
Fund, and the related Statements of Operations and Changes in Net Assets and

reflect, in all material respects, the financial condition of the Acquiring Fund
as of such date and the results of its operations for the period then ended, and

significant change or other factor that could significantly affect the internal

any other purpose of this Agreement), a decline in NAV per Acquiring Fund share
arising out of its normal investment operations or a decline in market values of

adverse change;

Closing Date, the Trust reasonably expects that the Acquiring Fund will be able
to meet the requirements of Subchapter M of the Code for qualification and

federal income tax under Section 852 of the Code. The Acquiring Fund has not
taken any action,

deficiency has been proposed or threatened;

               (G) The Acquiring Fund has no actual or potential liability for
any Tax obligation of any taxpayer other than itself. The Acquiring Fund is not

any item of income in, or exclude any item of deduction from, taxable income for
any taxable period (or portion thereof) ending after the Closing Date as a

                        EXPENSES AND RELATED INFORMATION

     The table below shows the fees and expenses that you would pay if you were
to buy and hold shares of each fund. The table does not reflect any charges that
may be imposed by institutions directly on their customer accounts in connection
with investments in either fund. The expenses appearing in the table below for
each fund are based on the fund's expenses for the twelve-month period ended
December 31, 2008. Future expenses may be greater (after expiration of the
contractual expense limitations described below) or less. The table also shows
the estimated ("pro forma") expenses of the combined fund assuming the
reorganization occurred on December 31, 2008. Pro forma expense levels shown
should not be considered an actual representation of future expenses or
performance. Such pro forma expense levels project anticipated expenses but
actual expenses may be greater or less than those shown.

Example

     The hypothetical example below helps you compare the cost of investing in
each fund with the cost of investing in other mutual funds. The example
illustrates the cost you would have incurred on an initial $10,000 investment in
each class of each fund over the time periods shown. It assumes your investment
earns an annual return of 5% over the periods, that total operating expenses
remain the same and that the contractual fee waivers and reimbursements by BGFA
and BGI are in effect for two years.

     THE FUNDS DO NOT CHARGE A SALES LOAD OR OTHER FEE UPON REDEMPTION. This
means that your cost for each period would be the same whether or not you sell
your shares at the end of a period. Your actual costs may be higher or lower
than this hypothetical example:

                             PERFORMANCE INFORMATION

Comparison of Fund Performance

     Set forth below is performance information for each fund, which indicates
some of the risks of investing in each fund. The first set of tables shows how
each fund's total return has varied from year to year for each full calendar
year. The first set of tables shows the returns for each class of each fund for
each of the last ten calendar years. The second set of tables shows average
annual total return (before and after taxes) for each fund over time as compared
with a broad-based securities market index. The average annual total return
tables compare the average annual total returns (before and after taxes) of
class of each fund to those of a corresponding index for various periods of
time.

     Effective March 15, 2004, the returns for each fund reflects its Master
Portfolio's investment in Underlying Funds. For periods prior to March 15, 2004,
the returns for each fund reflect the direct investment by its Master Portfolio
in a portfolio of securities and also reflect investment in accordance with a
model that included "tactical," or short-term, shifts in allocation between
stocks and bonds. In addition, as of December 31, 2003, BGFA made certain
changes to its asset allocation strategies for the funds, including a change to
the frequency with which the funds' respective holdings were rebalanced among
asset classes from monthly to quarterly.

     How the funds performed in the past (before and after taxes) is not
necessarily an indication of how they will perform in the future. You should
note that the investment adviser and portfolio managers of the combined fund
after the reorganization will be the same as your fund's and the Acquiring
Fund's investment adviser and portfolio managers. BGFA has reported that as of
November 2009, your fund and the Acquiring Fund will both have the same
investment objective, strategies, policies and restrictions and the most
conservative allocation within the LifePath strategy. However, prior to November
2009, the investment objective and policies of your fund were similar, but not
identical, to the investment objective, policies and strategies of the Acquiring
Fund, which causes the funds to have different risk/return profiles. Both your
fund and the Acquiring Fund benefited from an expense limitation agreement
during various periods. In the absence of such expense limitation agreement, the
funds' performance would have been lower.

/(1)/ Effective March 15, 2004, the returns for each LifePath Portfolio reflect
      its Master Portfolio's investment in Underlying Funds. For all periods
      prior to March 15, 2004, the returns for each LifePath Portfolio reflect
      the direct investment by its Master Portfolio in a portfolio of securities
      and also reflect investment in accordance with a model that included
      "tactical," or short-term, shifts in allocation between stocks and bonds.
      In addition, as of December 31, 2003, BGFA made certain changes to its
      asset allocation strategies for the LifePath Portfolios, including a
      change to the frequency with which the LifePath Portfolios' respective
      holdings were rebalanced among asset classes from monthly to quarterly.

/(2)/ The inception date of the Class I Shares of the LifePath Retirement
      Portfolio and LifePath 2010 Portfolio is March 1, 1994. The inception date
      of the LifePath Retirement Portfolio Custom Benchmark and LifePath 2010
      Portfolio Custom Benchmark is March 1, 1994.

/(3)/ After tax returns in the table above are calculated using the historical
      highest individual federal marginal income tax rates and do not reflect
      the impact of state, local or foreign taxes. Actual after-tax returns
      depend on an investor's tax situation and may differ from those shown, and
      after-tax returns shown are not relevant to tax-exempt investors or
      investors who hold shares through tax-deferred arrangements, such as
      401(k) plans or individual retirement accounts ("IRAs"). A LifePath
      Portfolio's returns after taxes on distributions and sale of LifePath
      Portfolio shares are calculated assuming that an investor has sufficient
      capital gains of the same character from other investments to offset any
      capital losses from the sale of LifePath Portfolio shares. As a result, a
      LifePath Portfolio's returns after taxes on distributions and sale of
      LifePath Portfolio shares may exceed the LifePath Portfolio's returns
      before taxes and/or returns after taxes on distributions.

/(4)/ The LifePath Portfolios' custom benchmarks are hypothetical
      representations of the performance of the respective LifePath Portfolio's
      asset classes according to their weightings as of the most recent quarter
      end. The weightings of the various indexes that are included in the
      LifePath Portfolios' custom benchmarks are adjusted quarterly to reflect
      the LifePath Portfolios' changing asset allocations over time. As of
      December 31, 2008, the following indexes are used to calculate the
      LifePath Portfolios' custom benchmarks: S&P 500 Index, S&P 400 Index, S&P
      600 Index, Barclays Capital U.S. Aggregate Bond Index, Citigroup 3-Month
      Treasury Bill Index, Barclays Capital U.S. Treasury Inflation Protected
      Securities (TIPS) Index (Series-L), MSCI All Country World Index ex US IMI
      Index and FTSE EPRA/NAREIT Global Real Estate Index. The MSCI All Country
      World Index ex US IMI Index replaced the MSCI All Country World Index ex
      USA Index on July 1, 2008. The FTSE EPRA/NAREIT Global Real Estate Index
      replaced the Cohen & Steers Realty Majors Index on July 1, 2008.

/(5)/ Reflects no deductions for fees, expenses or taxes.

/(6)/ Effective November 3, 2008, the names of the noted indexes changed from
      the Lehman Brothers U.S. Aggregate Index and Lehman Brothers U.S. Treasury
      TIPS Index to the Barclays Capital U.S. Aggregate Bond Index and Barclays
      Capital U.S. Treasury Inflation Protected Securities (TIPS) Index
      (Series-L), respectively. Changes to these indexes are discussed further
      in the May 2009 Prospectus.

BGFA and BGI have in the past waived and may from time to time agree to waive
all or a portion of their fees or reimburse expenses to a Master Portfolio or
LifePath Portfolio. When they do so, the applicable LifePath Portfolio's
operating expenses are reduced so that the LifePath Portfolio's total return is
increased. These waivers and reimbursements may be discontinued at any time,
except as described in footnotes 1 and 2 to the Fees and Expenses tables above.
In the absence of such waivers and/or reimbursements, the applicable LifePath
Portfolio's total return would be lower.

      Class R Shares commenced operations) reflects the performance of the Class
      I Shares adjusted to reflect the fees and expenses of the Class R Shares.
      Performance from April 30, 2001 reflects the actual performance of Class R
      Shares. Effective May 1, 2005, Class R Shares are sold without any sales
      charges. Effective March 15, 2004, the returns for each LifePath Portfolio

      BGFA made certain changes to its asset allocation strategies for the
      LifePath Portfolios, including a change to the frequency with which the
      LifePath Portfolios' respective holdings were rebalanced among asset
      classes from monthly to quarterly.

      after-tax returns shown are not relevant to tax-exempt investors or
      investors who hold shares through tax-deferred arrangements, such as
      401(k) plans or IRAs. A LifePath Portfolio's returns after taxes on
      distributions and sale of LifePath Portfolio shares are calculated
      assuming that an investor has sufficient capital gains of the same
      character from other investments to offset any capital losses from the
      sale of LifePath Portfolio shares. As a result, a LifePath Portfolio's
      returns after taxes on distributions and sale of LifePath Portfolio shares
      may exceed the LifePath Portfolio's returns before taxes and/or returns
      after taxes on distributions.

/(4)/ The LifePath Portfolios' custom benchmarks are hypothetical
      representations of the performance of the respective LifePath Portfolio's
      asset classes according to their weightings as of the most recent quarter
      end. The weightings of the various indexes that are included in the
      LifePath Portfolios' custom benchmarks are adjusted quarterly to reflect
      the LifePath Portfolios' changing asset allocations over time. As of
      December 31, 2008, the following indexes are used to calculate the
      LifePath Portfolios' custom benchmarks: S&P 500 Index, S&P 400 Index, S&P
      600 Index, Barclays Capital U.S. Aggregate Bond Index, Citigroup 3-Month

      World Index ex US IMI Index replaced the MSCI All Country World Index ex

      replaced the Cohen & Steers Realty Majors Index on July 1, 2008.

BGFA and BGI have in the past waived and may from time to time agree to waive
all or a portion of their fees or reimburse expenses to a Master Portfolio or
LifePath Portfolio. When they do so, the applicable LifePath Portfolio's
operating expenses are reduced so that the LifePath Portfolio's total return is
increased. These waivers and reimbursements may be discontinued at any time,
except as described in footnotes 1 and 2 to the Fees and Expenses tables above.
In the absence of such waivers and/or reimbursements, the applicable LifePath
Portfolio's total return would be lower.

Overview

INTRODUCTION

The LifePath Portfolios/1/ are designed to offer individual investors
comprehensive asset allocation strategies tailored to the time when they expect
to begin withdrawing assets. Asset allocation is the distribution of
investments among broad types of asset classes: equity securities, bonds and
money market instruments. Each LifePath Portfolio invests all of its assets in
a separate mutual fund, called a Master Portfolio, that has a substantially
identical investment objective as the LifePath Portfolio. To implement the
asset allocation strategy, each Master Portfolio, in turn, invests in a
combination of equity securities, bond and money market funds (the "Underlying
Funds") in proportions based on its own comprehensive investment strategy that
gradually becomes more conservative as the year in the LifePath Portfolio's
name approaches, except for the LifePath Retirement Portfolio, which is already
in its most conservative phase. Barclays Global Fund Advisors ("BGFA") is the
investment adviser to the Master Portfolios.

WHICH LIFEPATH PORTFOLIO TO CONSIDER

The first step in choosing which LifePath Portfolio to consider is answering a
key question: When will you need the money you are thinking of investing? Will
it be in ten years, when your kids are ready for college? Or 30 years, when you
retire?

The number in the name of most of the LifePath Portfolios is actually a year -
a "target year" when you might expect to begin withdrawing your money.
Selecting the LifePath Portfolio that may be most appropriate for your
investment may be as simple as matching your target year with the closest
LifePath Portfolio target year.

For example, let's say that you are investing for retirement purposes, and that
you expect to retire at age 60. If you are 45 years old, you have 15 years
before retirement. By adding 15 to the current year, you can define your
"target year." If you expect to retire in the year 2023, as in this example,
you may conclude that the LifePath 2020 Portfolio is the most appropriate
LifePath Portfolio for you.

(1)For simplicity's sake, all discussion of investment objective, strategies
   and risks of a particular LifePath Portfolio refers also to the investment
   objective, strategies and risks of the Master Portfolio, unless otherwise
   indicated. A detailed description of the relationship of the LifePath
   Portfolios to their Master Portfolios appears under the heading
   "Shareholder Information - Master/Feeder Mutual Fund Structure" in this
   Prospectus.

LIFEPATH(Reg. TM) PORTFOLIOS - HOW THEY WORK

[GRAPHIC APPEARS HERE]

NOTE: THE ABOVE CHART IS FOR ILLUSTRATIVE PURPOSES ONLY AND DOES NOT REPRESENT
THE ACTUAL ALLOCATION PERCENTAGES OF THE LIFEPATH PORTFOLIOS.

The chart shows that over time, the investment mix of each LifePath Portfolio
gradually shifts from a greater concentration of higher-risk investments
(namely, equity securities funds) to a greater concentration of lower-risk
investments (namely, bond funds), thereby making the LifePath Portfolio
increasingly conservative.

In making your investment decision, you should keep in mind:

[] Each LifePath Portfolio's investment strategy derives from the risk
 tolerance of average investors with a particular time horizon.

[] Each LifePath Portfolio's time horizon is based on the year in its name,
 except for the LifePath Retirement Portfolio, which is designed for investors
 who are currently withdrawing, or plan in the near future to begin
 withdrawing, a substantial portion of their investment.

If you are willing to accept a greater risk of short-term loss in exchange for
the potential to achieve higher long-term returns, you may invest some or all
of your assets in a LifePath Portfolio with a longer time horizon. If you
desire a more conservative investment and are willing to forego some potential
returns, you may invest some or all of your assets in a LifePath Portfolio with
a shorter time horizon. The final choice is yours.

Investment Objectives

Each LifePath Portfolio seeks to maximize return consistent with the
quantitatively measured risk that investors on average may be willing to accept
given their investment time horizon. An investor's time horizon marks the point
when the investor plans to start making net withdrawals from his or her
investments. As a general rule, investors with a longer time horizon have a
greater tolerance for risk than investors with a shorter time horizon.
Long-term investors are more likely to accept a greater risk of short-term loss
in exchange for the potential to achieve higher long-term returns. Each
LifePath Portfolio has its own time horizon, which affects the targeted risk
level of the LifePath Portfolio and, in turn, its asset allocation.

SPECIFICALLY:

[] LifePath Retirement Portfolio is managed for investors seeking income and
moderate long-term growth of capital.

[] LifePath 2010 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2010.

[] LifePath 2020 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2020.

[] LifePath 2030 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2030.

[] LifePath 2040 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2040.

[] LifePath 2050 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2050.

Each LifePath Portfolio's investment objective may be changed by the LifePath
Portfolio's Board of Trustees without shareholder approval.

                                                                              3



Summary of Principal Investment Strategies
Each LifePath Portfolio invests all of its assets in a corresponding Master
Portfolio which allocates and reallocates its assets among the Underlying
Funds. The Master Portfolios with longer time horizons invest a greater portion
of their assets in Underlying Funds that invest in equity securities, which
provide a greater opportunity for capital appreciation over the long-term but
have a greater risk of short-term loss. The Master Portfolios with shorter time
horizons invest a greater portion of their assets in Underlying Funds that
invest in bonds and money market instruments, which typically offer reduced
risk and price volatility but forego some potential returns. Accordingly, under
normal circumstances, the LifePath Portfolios with shorter time horizons have
lower expected returns than the LifePath Portfolios with longer time horizons.

[] LifePath Retirement Portfolio is designed for investors seeking current
 income and moderate long-term growth of capital. As of March 31, 2009, the
 LifePath Retirement Portfolio held approximately 38% of its assets in
 Underlying Funds that invest primarily in equity securities, 62% of its assets
 in Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 Because the LifePath Retirement Portfolio is in its most conservative phase,
 its allocation generally does not become more conservative over time, although
 its allocation may change to maintain the LifePath Retirement Portfolio's risk
 profile.

[] LifePath 2010 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2010. As of March 31, 2009, the
 LifePath 2010 Portfolio held approximately 40% of its assets in Underlying
 Funds that invest primarily in equity securities, 60% of its assets in
 Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 As the stated time horizon approaches, the allocation will become more
 conservative and have lower expected returns.

[] LifePath 2020 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2020. As of March 31, 2009, LifePath
 2020 Portfolio held approximately 61% of its assets in Underlying Funds that
 invest primarily in equity securities, 39% of its assets in Underlying Funds
 that invest primarily in bonds and the remainder of its assets in Underlying
 Funds that invest primarily in money market instruments. As the stated time
 horizon approaches, the allocation will become more conservative and have
 lower expected returns.

[] LifePath 2030 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2030. As of March 31, 2009, the
 LifePath 2030 Portfolio held approximately 76% of its assets in Underlying
 Funds that invest primarily in equity securities, 24% of its assets in
 Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 As the stated time horizon approaches, the allocation will become more
 conservative and have lower expected returns.

[] LifePath 2040 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2040. As of March 31, 2009, the
 LifePath 2040 Portfolio held approximately 89% of its assets in Underlying
 Funds that invest primarily in equity securities, 11% of its assets in
 Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 As the stated time horizon approaches, the allocation will become more
 conservative and have lower expected returns.

[] LifePath 2050 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2050. As of March 31, 2009, the
 LifePath 2050 Portfolio held approximately 99% of its assets in Underlying
 Funds that invest primarily in equity securities, 1% of its assets in
 Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 As the stated time horizon approaches, that allocation will become more
 conservative and have lower expected returns.

When a LifePath Portfolio reaches its stated time horizon and enters its most
conservative phase - E.G., the LifePath 2010 Portfolio - the allocation of its
assets is expected to be similar to that of the LifePath Retirement Portfolio.
Such LifePath Portfolio and the LifePath Retirement Portfolio may then continue
to operate as separate funds or, subject to approval by the LifePath
Portfolios' Board of Trustees, they may be merged into a single fund.

Summary of Principal Risk Factors

As with any investment, your investment in the LifePath Portfolios could lose
money or the Portfolios' performance could trail that of other investments.

EACH LIFEPATH PORTFOLIO HAS A DIFFERENT LEVEL OF RISK.

The value of your investment is subject to equity securities market risk, which
means the price of the equity securities in which the Underlying Funds invest
may fluctuate or fall in response to economic events or trends.

The value of your investment is also subject to bond investment risks,
including interest rate risk, which means that the prices of bonds in which the
Underlying Funds invest may fall because of a rise in interest rates; credit
risk, which is the risk that the price of an individual bond may fall with the
decline in an issuer's real or apparent ability to meet its financial
obligations; extension risk, which is the risk that borrowers may extend the
prepayment of their mortgages or loans for longer periods than expected,
thereby affecting the security's average life and, potentially, its yield; and
prepayment risk, which is the risk that borrowers may prepay their mortgages or
loans faster than expected, thereby affecting the security's average life and,
potentially, its yield. The risk of default and price volatility of high yield
securities is greater than the risk usually associated with higher-rated
securities.

Investments in foreign securities by the Underlying Funds are subject to
certain special risks and considerations, including potentially less liquidity
and greater price volatility than investments in securities traded in the U.S.
markets. These risks are greater for investments in foreign securities issued
by companies or sovereign entities in emerging market countries.

The allocation of each LifePath Portfolio's assets is managed using a
quantitative model that has been developed based on a number of factors.
Neither the LifePath Portfolios nor BGFA can offer any assurance that the
recommended asset allocation will either maximize returns or minimize risk or
be the appropriate allocation in all circumstances for every investor with a
particular time horizon.

The value of your investment is also subject to passive investment risk,
security selection risk and concentration risk. Because BGFA does not select
individual companies in the underlying indexes for certain Underlying Funds,
those Underlying Funds may hold stocks in companies that present risks that an
adviser researching individual stocks might seek to avoid. This is known as
passive investment risk. In the case of the Underlying Funds where BGFA does
select securities based on its analysis, these funds are subject to the risk
that security selection will contribute to underperformance. Concentration risk
is the risk that an Underlying Fund that concentrates in a single industry or
group of industries may be more susceptible to any single economic, market,
political or regulatory occurrence in that industry or group of industries.

The value of your investment is subject to real estate investment risk, which
includes many of the same risks associated with the direct ownership of real
estate.

Investments in derivatives by certain Underlying Funds are subject to special
risks and considerations. Derivatives are financial instruments whose values
are derived, at least in part, from the prices of other securities or specified
assets, indexes or rates.

Certain Underlying Funds are also subject to market trading risks due to their
shares being listed and traded on securities exchanges (including potential
halts in trading or a fluctuation in trading price in accordance with changes
in net asset value), and tracking error risk, in that the return of an
Underlying Fund that seeks to track an index may deviate from the return of
such index.

- --------------------------------------------------------------------------------
                                                                              5



The LifePath Portfolios must maintain cash balances to meet redemption
requests, which may lower overall portfolio performance.

An investment in a LifePath Portfolio is not a bank deposit and it is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

Investment Returns

TOTAL RETURNS

The bar charts and table in this section provide some indication of the risks
of investing in the LifePath Portfolios by showing the changes in their
performance from year to year. The bar charts show the returns for Class I of
each LifePath Portfolio for each of the last ten calendar years. The average
annual total return table compares the average annual total returns (before and
after taxes) of Class I of each LifePath Portfolio to those of a corresponding
index for various periods of time. Effective March 15, 2004, the returns for
each LifePath Portfolio reflect its Master Portfolio's investment in Underlying
Funds. For all periods prior to March 15, 2004, the returns for each LifePath
Portfolio reflect the direct investment by its Master Portfolio in a portfolio
of securities and also reflect investment in accordance with a model that
included "tactical," or short-term, shifts in allocation between stocks and
bonds. In addition, as of December 31, 2003, BGFA made certain changes to its
asset allocation strategies for the LifePath Portfolios, including a change to
the frequency with which the LifePath Portfolios' respective holdings were
rebalanced among asset classes from monthly to quarterly.

How the LifePath Portfolios performed in the past (before and after taxes) is
not necessarily an indication of how they will perform in the future.

  (1)   Effective March 15, 2004, the returns for each LifePath Portfolio
        reflect its Master Portfolio's investment in Underlying Funds. For all
        periods prior to March 15, 2004, the returns for each LifePath
        Portfolio reflect the direct investment by its Master Portfolio in a
        portfolio of securities and also reflect investment in accordance with
        a model that included "tactical," or short-term, shifts in allocation
        between stocks and bonds. In addition, as of December 31, 2003, BGFA
        made certain changes to its asset allocation strategies for the
        LifePath Portfolios, including a change to the frequency with which the
        LifePath Portfolios' respective holdings were rebalanced among asset
        classes from monthly to quarterly.

  (2)   The inception date of the Class I Shares of the LifePath Retirement
        Portfolio, LifePath 2010 Portfolio, LifePath 2020 Portfolio, LifePath
        2030 Portfolio and LifePath 2040 Portfolio is March 1, 1994. The
        inception date of the Class I Shares of the LifePath 2050 Portfolio is
        June 30, 2008. The returns for the Class I Shares of the LifePath 2050
        Portfolio are not annualized. The inception date of the LifePath
        Retirement Portfolio Custom Benchmark, LifePath 2010 Portfolio Custom
        Benchmark, LifePath 2020 Portfolio Custom Benchmark, LifePath 2030
        Portfolio Custom Benchmark and LifePath 2040 Portfolio Custom Benchmark
        is March 1, 1994. The inception date of the LifePath 2050 Portfolio
        Custom Benchmark is June 30, 2008.


  (3)   After tax returns in the table above are calculated using the
        historical highest individual federal marginal income tax rates and do
        not reflect the impact of state, local or foreign taxes. Actual
        after-tax returns depend on an investor's tax situation and may differ
        from those shown, and after-tax returns shown are not relevant to
        tax-exempt investors or investors who hold shares through tax-deferred
        arrangements, such as 401(k) plans or individual retirement accounts
        ("IRAs"). A LifePath Portfolio's returns after taxes on distributions
        and sale of LifePath Portfolio shares are calculated assuming that an
        investor has sufficient capital gains of the same character from other
        investments to offset any capital losses from the sale of LifePath
        Portfolio shares. As a result, a LifePath Portfolio's returns after
        taxes on distributions and sale of LifePath Portfolio shares may exceed
        the LifePath Portfolio's returns before taxes and/or returns after
        taxes on distributions.


  (4)   The LifePath Portfolios' custom benchmarks are hypothetical
        representations of the performance of the respective LifePath
        Portfolio's asset classes according to their weightings as of the most
        recent quarter end. The weightings of the various indexes that are
        included in the LifePath Portfolios' custom benchmarks are adjusted
        quarterly to reflect the LifePath Portfolios' changing asset
        allocations over time. As of December 31, 2008, the following indexes
        are used to calculate the LifePath Portfolios' custom benchmarks: S&P
        500 Index, S&P 400 Index, S&P 600 Index, Barclays Capital U.S.
        Aggregate Bond Index, Citigroup 3-Month Treasury Bill Index, Barclays
        Capital U.S. Treasury Inflation Protected Securities (TIPS) Index
        (Series-L), MSCI All Country World Index ex US IMI Index and FTSE
        EPRA/NAREIT Global Real Estate Index. The MSCI All Country World Index
        ex US IMI Index replaced the MSCI All Country World Index ex USA Index
        on July 1, 2008. The FTSE EPRA/NAREIT Global Real Estate Index replaced
        the Cohen & Steers Realty Majors Index on July 1, 2008.
  (5)   Reflects no deductions for fees, expenses or taxes.
  (6)   Effective November 3, 2008, the names of the noted indexes changed
        from the Lehman Brothers U.S. Aggregate Index and Lehman Brothers U.S.
        Treasury TIPS Index to the Barclays Capital U.S. Aggregate Bond Index
        and Barclays Capital U.S. Treasury Inflation Protected Securities
        (TIPS) Index (Series-L), respectively. Changes to these indexes are
        discussed further on page 21.

BGFA and BGI have in the past waived and may from time to time agree to waive
all or a portion of their fees or reimburse expenses to a Master Portfolio or
LifePath Portfolio. When they do so, the applicable LifePath Portfolio's
operating expenses are reduced so that the LifePath Portfolio's total return is
increased. These waivers and reimbursements may be discontinued at any time,
except as described in footnotes 1 and 2 to the Fees and Expenses table on the
immediately following page. In the absence of such waivers and/or
reimbursements, the applicable LifePath Portfolio's total return would be
lower.

Fees and Expenses

The table below describes the fees and expenses that you may pay if you buy and
hold Class I Shares of a LifePath Portfolio. The expenses are deducted from
each LifePath Portfolio's assets, which means you pay them indirectly. This
table does not reflect charges that may be imposed in connection with an
account in which you hold the shares. A broker-dealer or financial institution
maintaining the account in which you hold shares may charge a separate account,
service or transaction fee on the purchase or sale of Class I Shares that would
be in addition to the fees and expenses shown here.

The total annual operating expense ratios in the table and the example on the
next page reflect the expenses of the Class I Shares of each LifePath Portfolio
and its corresponding Master Portfolio and also reflect a weighted average of
the total operating expense ratios of the Underlying Funds in which each Master
Portfolio invests:

  (1)   BGFA, the investment adviser to the Master Portfolios, has
        contractually agreed to waive its management fees at the Master
        Portfolio level in an amount equal to advisory fees and administration
        fees, if any, charged to the Underlying Funds through April 30, 2011
        (the "contractual waiver").
  (2)   "Independent Expenses" consist of those fees and expenses of the
        Independent Trustees of the LifePath Portfolios and the Master

        are allocated to the Class I Shares of the LifePath Portfolios.
        Barclays Global Investors, N.A. ("BGI") and BGFA, as applicable, have
        contractually agreed to reimburse, or provide offsetting credits to,
        the Class I Shares of the LifePath Portfolios and the Master Portfolios
        for Independent Expenses through April 30, 2011. After giving effect to
        such contractual arrangements, Independent Expenses will be 0.00%. For

EXAMPLE

The example below is intended to help you compare the cost of investing in
Class I Shares of the LifePath Portfolios with the cost of investing in other
mutual funds. The example illustrates the cost you would have incurred on an
initial $10,000 investment in Class I Shares of each LifePath Portfolio over
the time periods shown. It assumes your investment earns an annual return of 5%
over the periods, that total operating expenses remain the same and that the
contractual fee waivers and reimbursements by BGFA and BGI are in effect for
two years.

THE LIFEPATH PORTFOLIOS DO NOT CHARGE A SALES LOAD OR OTHER FEE UPON
REDEMPTION. This means that your cost for each period would be the same whether
or not you sell your shares at the end of a period. Your actual costs may be
higher or lower than this hypothetical example:

A Further Discussion of Principal Investment Strategies

INTRODUCTION

Each LifePath Portfolio pursues a common strategy of allocating and
reallocating its assets among the Underlying Funds. The LifePath Portfolios
with longer time horizons invest a greater portion of their assets in
Underlying Funds that invest in equity securities, which provide a greater
potential to achieve higher returns over the long-term but have a greater risk
of short-term loss. In addition to investing in Underlying Funds, each LifePath
Portfolio may borrow, lend its portfolio securities to brokers, dealers and
financial institutions, and may invest the collateral in certain short-term
instruments either directly or through one or more joint accounts or money
market funds, as described in greater detail in the LifePath Portfolios'
combined Statement of Additional Information ("SAI").

The LifePath Portfolios with shorter time horizons invest a greater portion of
their assets in Underlying Funds that invest in bonds and money market
instruments, which typically offer reduced risk and price volatility, but
forego some potential returns. Accordingly, under normal circumstances, the
LifePath Portfolios with shorter time horizons have lower expected returns than
the LifePath Portfolios with longer time horizons. As each LifePath Portfolio
approaches its designated time horizon, it systematically seeks to reduce the
level of risk by allocating assets more conservatively among the Underlying
Funds. This systematic shift toward more conservative investments is designed
to reduce the risk of significant reductions in the value of an investment in a
LifePath Portfolio as it approaches its time horizon.

For example, the LifePath Retirement Portfolio has entered its "retirement
phase" and seeks to maximize returns consistent with the risk that an average
investor in retirement may be willing to accept. This does not mean, however,
that it invests exclusively, or primarily, in Underlying Funds that are money
market funds. Rather, because BGFA believes that most investors are still
willing to take some risks in pursuing returns even while drawing on their
investments, a portion of the LifePath Retirement Portfolio's assets will
continue to be allocated to Underlying Funds that are equity and bond funds, in
addition to Underlying Funds that are money market funds.

In determining the allocation of assets to the Underlying Funds, BGFA uses a
proprietary investment model that analyzes securities market data, including
risk, asset class correlations, and expected returns, to provide portfolio
allocations among the asset classes represented by the Underlying Funds. The
allocations are periodically monitored and rebalanced in an effort to maximize
expected return for a given level of risk. In managing the LifePath Portfolios,
BGFA focuses on long-term targets and objectives. The progression over time of
a LifePath Portfolio's asset allocation to more conservative asset classes is a
relatively steady process resulting in only gradual changes to the asset
allocation from quarter to quarter. The Underlying Funds invest in a mix of
equity securities, bonds and money market instruments. Certain Underlying Funds
invest in real estate investment trusts ("REITs"), foreign securities, emerging
markets, below investment-grade bonds and derivatives, which are subject to
additional risks, as described in the "Further Discussion of Principal Risk
Factors" section of this Prospectus. The investment model adjusts each LifePath
Portfolio's risk level by gradually making it more conservative as the year in
the LifePath Portfolio's name approaches, except for the LifePath Retirement
Portfolio, which is already in its most conservative phase.

THE UNDERLYING FUNDS

Two of the Underlying Funds - the Active Stock Master Portfolio and the
CoreAlpha Bond Master Portfolio (collectively, the "Underlying Master
Portfolios") - are diversified portfolios of Master Investment Portfolio
("MIP"). The Active Stock Master Portfolio seeks to provide long-term
appreciation of capital. BGFA invests the Active Stock Master Portfolio's
assets using a proprietary quantitative model that is designed to select stocks
based on an analysis of a wide range of company-specific factors. The CoreAlpha
Bond Master Portfolio seeks to provide a combination of income and capital
growth. BGFA invests the CoreAlpha Bond Master Portfolio's assets pursuant to a
systematic method that relies on

proprietary quantitative models to allocate assets among various bond sectors
by evaluating each sector's relative value and risk-adjusted return.

The remaining Underlying Funds, other than the Barclays Global Investors Funds
("BGIF") Institutional Money Market Fund (the "Underlying Money Market Fund")
are exchange-traded funds ("ETFs") that are part of the iShares family of funds
("Underlying iShares Funds"). Each of the Underlying iShares Funds seeks
investment results that correspond generally to the performance, before fees
and expenses, of its underlying index. As a result, adverse performance of a
particular security in an Underlying iShares Fund's portfolio will ordinarily
not result in the elimination of the security from the Underlying iShares
Fund's portfolio. Each Underlying iShares Fund offers and issues iShares at
their net asset value per share only to certain institutional investors in
aggregations of a specified number of iShares, generally in exchange for a
basket of securities included in its underlying index, together with the
deposit of a specified cash payment. The iShares for these Underlying iShares
Funds are listed and traded on national securities exchanges and also may be
listed on certain non-U.S. exchanges. BGFA purchases iShares on behalf of the
Master Portfolios in the secondary market.

The relative weightings for each Master Portfolio in the various Underlying
Funds will vary over time, and BGFA is not required to invest any Master
Portfolio's assets in each of the Underlying Funds or in any particular
percentage in any given Underlying Fund. BGFA may add, eliminate or replace
Underlying Funds at any time.

Each Master Portfolio currently expects to invest in some or all of the
Underlying Funds described below:

ACTIVE STOCK MASTER PORTFOLIO

Seeks to provide long-term appreciation of capital. The Active Stock Master
Portfolio invests, under normal circumstances, at least 80% of its assets in
common stocks. The Active Stock Master Portfolio invests primarily in equity
securities of U.S. companies with market capitalizations similar to the range
of market capitalizations represented in the Standard & Poor's S&P 500 Index.
BGFA invests the Active Stock Master Portfolio's assets using a proprietary
quantitative model that is designed to select stocks based on an analysis of a
wide range of company-specific factors, such as relative values based on
earnings and cash flows; earnings quality as measured by the company's
financial condition and earnings reports; sentiment as expressed through
management and market participant behavior; and industry classification. BGFA
considers risk parameters in deciding upon the Active Stock Master Portfolio's
aggregate holdings, and factors trading costs into its stock selection process.


COREALPHA BOND MASTER PORTFOLIO

Seeks to provide a combination of income and capital growth. BGFA invests the
CoreAlpha Bond Master Portfolio's assets pursuant to a systematic method that
relies on proprietary quantitative models to allocate assets among various bond
sectors by evaluating each sector's relative value and risk-adjusted return.
BGFA's models also allocate assets among bonds of different maturities based on
yield characteristics and expectations. Specific investment selection decisions
are made on the basis of evaluations of relative value, credit quality and
other factors. The CoreAlpha Bond Master Portfolio invests, under normal
circumstances, at least 80% of its assets in bonds. For the purposes of this
strategy, "bonds" include the following: obligations issued or guaranteed by
the U.S. government, its agencies or instrumentalities; mortgage-backed
securities issued or guaranteed by the U.S. government, its agencies or
instrumentalities, including U.S. agency mortgage pass-through securities;
commercial mortgage-backed securities; debt obligations of U.S. corporations;
dollar-denominated debt obligations of foreign issuers; municipal securities;
and asset-backed securities. The CoreAlpha Bond Master Portfolio invests a
substantial portion of its assets in U.S.-registered, dollar-denominated bonds.
The CoreAlpha Bond Master Portfolio may invest in bonds of any maturity or
duration.

BGIF INSTITUTIONAL MONEY MARKET FUND

Seeks a high level of income consistent with liquidity and the preservation of
capital. The BGIF Institutional Money Market Fund invests in high-quality,
short-term money market instruments that include fixed-rate, floating-rate and
variable-rate debt securities. The BGIF Institutional Money Market Fund also
may invest in high-quality, short-term U.S.

and foreign government debt, including the debt of agencies and
instrumentalities, such as the Federal National Mortgage Association ("Fannie
Mae"), U.S. and foreign bank obligations, corporate obligations, repurchase
agreements and asset-backed securities.

UNDERLYING ISHARES FUNDS

In managing each of the Underlying iShares Funds, BGFA uses a representative
sampling index strategy. Representative sampling is an indexing strategy that
involves investing in a representative sample of securities that has an
investment profile similar to the underlying index. The securities selected are
expected to have, in the aggregate, investment characteristics (based on
factors such as market capitalization and industry weightings), fundamental
characteristics (such as return variability, duration, maturity or credit
ratings and yield) and liquidity measures similar to those of the applicable
underlying index. Underlying iShares Funds that use representative sampling may
or may not hold all of the securities in the relevant underlying index.

A Further Discussion of Principal Risk Factors

In addition to the principal risks of investing described in the "Summary of
Principal Risk Factors" section of this Prospectus, the LifePath Portfolios
have the following risks:

GENERAL

The net asset value of each LifePath Portfolio's shares ("NAV") is neither
insured nor guaranteed, is not fixed and will fluctuate.

GENERAL RISKS APPLICABLE TO THE LIFEPATH PORTFOLIOS

EQUITY SECURITIES MARKET RISKS

The risks of investing in the equity securities market include both short-term
and prolonged price declines. The value of an equity security may decline in
value due to factors affecting equity securities markets generally or
particular industries represented in the markets. Equity securities may
underperform fixed-income investments and securities market indexes that track
other markets, segments and sectors. Equity securities of mid- to small-cap
companies tend to present greater risks than equity securities of large-cap
companies because they are generally more volatile and can be less liquid.

BOND INVESTMENT RISKS

The risks of fixed-income investing include short-term and prolonged price
declines because of a rise in interest rates, issuer quality considerations and
other economic considerations; however, such price declines in the bond market
have historically been less severe than stock declines.

CREDIT RISK

Credit risk is the risk that issuers or guarantors of debt instruments or the
counterparty to a derivatives contract, repurchase agreement or loan of
portfolio securities is unable or unwilling to make timely interest and/or
principal payments or to otherwise honor its obligations. There is the chance
that any of an Underlying Fund's holdings will have their credit ratings
downgraded or will default (fail to make scheduled interest or principal
payments), potentially reducing an Underlying Fund's income level and share
price. Debt instruments are subject to varying degrees of credit risk, which
may be reflected in credit ratings. Securities issued by the U.S. government
have limited credit risk. However, securities issued by U.S. government
agencies (such as U.S. agency mortgage pass-through securities) are not
necessarily backed by the full faith and credit of the U.S. government.

INTEREST RATE RISK

Interest rate risk is the risk that bond prices will decline over short or even
long periods due to rising market interest rates. All bonds, including those
issued by the U.S. government and its agencies, are subject to interest rate
risk. Their prices tend to move in the opposite direction from market interest
rate movements. When interest rates go up, bond prices tend to fall; when rates
fall, prices tend to rise. Bonds with longer maturities are affected more by
interest rate movements than bonds with shorter maturities, bonds with interest
rate reset provisions, notes or money market instruments. If prices throughout
the economy were to decline over time, resulting in "deflation," the principal
and income of inflation-protected bonds held by an Underlying Fund would likely
decline in price, which would result in losses for the Underlying Fund.
Mortgage-backed securities represent interests in or instruments backed by a
pool of loans secured by mortgages and asset-backed securities represent
interests in or instruments backed by a pool of loans secured by other assets.
Mortgage-backed securities and asset-backed securities are also subject to
prepayment risk and extension risk. Prepayment risk is the risk that during
periods of falling interest rates, an issuer of mortgages and other securities
may be able to repay principal prior to the security's maturity, causing the
Underlying Fund to have to

- --------------------------------------------------------------------------------
     22                                        BARCLAYS GLOBAL INVESTORS FUNDS



reinvest in securities with a lower yield. Extension risk is the risk that when
interest rates rise, certain mortgage-backed securities will be paid off
substantially more slowly than originally anticipated and the value of those
securities may fall sharply. Both prepayment risk and extension risk may result
in a decline to the Underlying Funds' income.

HIGH YIELD SECURITIES RISK

High yield securities risk is the risk that securities that are rated below
investment-grade (commonly referred to as "junk bonds," include those bonds
rated lower than "BBB-" by S&P, a division of The McGraw-Hill Companies, Inc.
and Fitch Rating Service Inc. or "Baa3" by Moody's(Reg. TM) Investor's
Services, Inc.) or are unrated but judged by an Underlying Fund to be of
comparable quality, at the time of purchase, may be more volatile than
higher-rated securities of similar maturity.

High yield securities may also be subject to greater levels of credit or
default risk than higher-rated securities. The value of high yield securities
can be adversely affected by overall economic conditions, such as an economic
downturn or a period of rising interest rates, and high yield securities may be
less liquid and more difficult to sell at an advantageous time or price or to
value than higher-rated securities.

NON-U.S. SECURITIES RISKS

Investments in the securities of non-U.S. issuers are subject to all the risks
of investing in the market of such issuers, including market fluctuations
caused by factors such as economic and political developments, changes in
interest rates and abrupt changes in stock prices. As a result of Underlying
Funds' investing in non-U.S. securities, the Fund may be subject to the risks
listed below. These risks may decrease the value of your investment:

[] Lower levels of liquidity and market efficiency;

[] Greater securities price volatility;

[] Exchange rate fluctuations and exchange controls;

[] Less availability of public information about issuers;

[] Imposition of withholding or other taxes;

[] Imposition of restrictions on the expatriation of funds or other assets of
the Underlying Fund;

[] Higher transaction and custody costs and delays in settlement procedures;

[] Difficulties in enforcing contractual obligations;

[] Substantial government involvement in the economy;

[] Higher rates of inflation;

[] Greater social, economic and political uncertainty, the risk of
 nationalization or expropriation of assets and risk of war;

[] Lower levels of regulation of the securities markets;

[] Different accounting, disclosure and reporting requirements; and

[] Legal principles relating to corporate governance, director's fiduciary
 duties and liabilities and stockholder's rights in markets in which the
 Underlying Funds invest may differ and/or may not be as extensive or
 protective as those that apply in the United States.

Investments in non-U.S. securities may be made by an Underlying Fund directly
or through investments in American Depositary Receipts ("ADRs") and other
similar investments. ADRs are receipts for shares of non-U.S. stocks held on
deposit in U.S. banks or banks of major European countries. The receipts trade
on the U.S. or local European stock markets as would normal stocks, entitling
their owners to the dividends and capital gains earned by the real shares
stored in bank vaults. ADRs reduce some of the risks of foreign investing
because a large, liquid market generally exists

- --------------------------------------------------------------------------------
                                                                             23



and U.S. trading and settlement practices reduce currency, custodial and other
operational risks. Similar investments (European and Global Depositary
Receipts) are receipts for stock deposited in non-U.S. bank and trust
companies, trade across foreign and domestic markets, and can involve different
or greater risks than ADRs.

EMERGING MARKETS RISK

Some foreign markets are considered to be emerging markets. Investment in these
emerging markets is subject to a greater risk of loss than investments in a
developed market. This is due to, among other things, greater market
volatility, lower trading volume, political and economic instability, greater
risk of market shut down and more governmental limitations on foreign
investment policy than those typically found in a developed market.

MODEL RISK

Although the quantitative model used to manage the Master Portfolios' assets
has been developed and refined over many years, neither the Master Portfolios
nor BGFA can offer any assurance that the recommended allocation will either
maximize returns or minimize risks, nor can the Master Portfolios or BGFA offer
assurance that a recommended allocation will be the appropriate allocation in
all circumstances for every investor with a particular time horizon.

REAL ESTATE INVESTMENT RISK

Investment in equity securities in the real estate sector is subject to many of
the same risks associated with the direct ownership of real estate, such as
adverse changes in national, state or local real estate conditions (resulting
from, for example, oversupply of or reduced demand for space and changes in
market rental rates); obsolescence of properties; changes in the availability,
cost and terms of mortgage funds; and the impact of tax, environmental, and
other laws.

DERIVATIVES

Derivatives include, among other instruments, futures contracts, options on
futures contracts, other types of options that may be exchange-traded or traded
over-the-counter, indexed and inverse floating-rate securities, and swap
agreements. Derivatives are financial instruments whose values are derived, at
least in part, from the prices of other securities or specified assets, indexes
or rates. Some derivatives may be more sensitive than direct securities to
changes in interest rates or sudden market moves. Some derivatives also may be
susceptible to fluctuations in yield or value due to their structure or
contract terms.

PASSIVE INVESTMENT RISK

Because BGFA does not select individual companies in the underlying indexes for
the Underlying iShares Funds, those Underlying iShares Funds may hold stocks in
companies that present risks that an investment adviser researching individual
stocks might seek to avoid.

SECURITY SELECTION RISK

For each of Active Stock Master Portfolio and CoreAlpha Bond Master Portfolio,
BGFA bases security selection on its analysis of securities and therefore each
of these Master Portfolios is subject to the risk that poor security selection
will result in underperformance of the Master Portfolio in comparison with
other investment vehicles with similar investment objectives and strategies.

SECURITIES LENDING RISK

The LifePath Portfolios may also lend portfolio securities to borrowers that
provide collateral at least equal to the current market value of the securities
loaned, plus accrued interest or dividends. BGI acts as securities lending
agent for, and is compensated by, the LifePath Portfolios. Securities lending
collateral is generally reinvested in a joint account or money market funds,
including those advised by BGFA. Risks related to securities lending include
operational, credit, legal, counterparty and market risk, as well as investment
risks related to the collateral and risk of loss if the collateral is
liquidated.

     24                                        BARCLAYS GLOBAL INVESTORS FUNDS



CONCENTRATION RISK

To the extent that an underlying index of an Underlying iShares Fund is
concentrated in the securities of companies, a particular market industry,
group of industries, sector or asset class countries, regions or groups of
countries, that Underlying iShares Fund may be adversely affected by the
performance of those securities, may be subject to increased price volatility
and may be more susceptible to adverse economic, market, political or
regulatory occurrences affecting that market, industry, group of industries,
sector or asset class country, region or group of countries.

MARKET TRADING RISKS

The Underlying iShares Funds are subject to certain additional risks due to
their shares being listed and traded on securities exchanges. There can be no
assurance that an active trading market for these particular ETFs will develop
or be maintained. Trading in ETFs may be halted because of market conditions or
for reasons that, in the view of the listing exchange, make trading in ETFs
inadvisable. In addition, trading in ETFs is subject to trading halts caused by
extraordinary market volatility pursuant to "circuit breaker" rules. There can
be no assurance that the requirements necessary to maintain the listing of ETFs
will continue to be met or will remain unchanged. An ETF may trade at, above or
below its NAV. The NAV of an ETF will fluctuate with changes in the market
value of its holdings. The trading price of an ETF will generally fluctuate in
accordance with changes in its NAV, as well as market supply and demand.

TRACKING ERROR RISK

Imperfect correlation between an Underlying iShares Fund's securities and those
in its underlying index, rounding of prices, changes to the underlying index
and regulatory requirements, may cause "tracking error," which is measured as
the divergence of the Underlying iShares Fund's performance from that of its
underlying index. Tracking error also may result because an Underlying iShares
Fund incurs fees and expenses while its underlying index does not incur the
same expenses.

Management of the LifePath Portfolios

INVESTMENT ADVISER

Each LifePath Portfolio is a feeder fund that invests all of its assets in a
Master Portfolio that has a substantially identical investment objective,
strategies and policies as the LifePath Portfolio. The Master Portfolios, in
turn, invest in a combination of the Underlying Funds. BGFA, a registered
investment adviser, serves as investment adviser to each Master Portfolio, and
also serves as investment adviser to each Underlying Fund, with the exception
of the Underlying Money Market Fund, which invests in a Master Portfolio
advised by BGFA. BGFA manages the investing of the Master Portfolios' assets
and provides the Master Portfolios with investment guidance and policy
direction in connection with daily portfolio management, subject to the
supervision of the Master Portfolios' Board of Trustees. For its services to
the Master Portfolios, BGFA is entitled to receive an annual advisory fee of
0.35% of each Master Portfolio's average daily net assets.

For its services to the Underlying Funds, BGFA receives fees that differ from
the fees described for the LifePath Portfolios in this Prospectus. BGFA
provides investment advisory services for the Underlying Funds that differ from
the investment advisory services it provides for the Master Portfolios. For
those services, BGFA receives investment advisory fees from the Underlying
Funds. In addition, BGI provides administration services to certain of the
Underlying Funds and, for those services, may receive administration fees from
those Underlying Funds. BGFA has contractually agreed to waive its management
fees at the Master Portfolio level in an amount equal to advisory and
administration fees, if any, paid by the Underlying Funds to BGFA and BGI,
respectively, through April 30, 2011.

BGFA is located at 400 Howard Street, San Francisco, CA 94105. It is a
wholly-owned subsidiary of BGI, which in turn is a majority-owned subsidiary of
Barclays Bank PLC. As of February 28, 2009, BGI and its affiliates, including
BGFA, provided investment advisory services for assets in excess of $1.36
trillion. BGI, BGFA, Barclays Global Investors Services, Barclays Bank PLC and
their affiliates deal, trade and invest for their own accounts in the types of
securities in which the Master Portfolios invest.

A discussion regarding the basis for the Master Portfolios' Board of Trustees'
approval of the investment advisory agreements with BGFA is available in each
LifePath Portfolio's semi-annual report for the six-month period ending June
30.

PORTFOLIO MANAGERS

Dagmar Nikles, Leslie Gambon and Dale Hogan (the "Portfolio Managers") are
primarily responsible for the day-to-day management of the Master Portfolios
and act collaboratively on all aspects concerning the Master Portfolios. Each
Portfolio Manager is responsible for various functions related to portfolio
management, including, but not limited to, investing cash inflows, coordinating
with members of their team to focus on certain asset classes, implementing
investment strategy, researching and reviewing investment strategy, and
overseeing members of his or her portfolio management team with more limited
responsibilities.

Ms. Nikles is an employee of BGFA and BGI and has been one of the Portfolio
Managers primarily responsible for the day-to-day management of the Master
Portfolios since June 2005. Ms. Nikles has been a member of the asset
allocation portfolio management team since July 2003. From September 2002 to
June 2003, Ms. Nikles was pursuing her Financial Risk Manager certification.

Ms. Gambon is an employee of BGFA and BGI and has been one of the Portfolio
Managers primarily responsible for the day-to-day management of the Master
Portfolios since May 2007. Ms. Gambon has been a member of the asset allocation
portfolio management team since April 2007. Prior to becoming a member of the
asset allocation portfolio

- --------------------------------------------------------------------------------
     26                                        BARCLAYS GLOBAL INVESTORS FUNDS



management team, Ms. Gambon was an Active Equity Product Manager with BGI from
2001 to 2004 and in October 2004 became Head of Defined Contribution Portfolio
Management at BGI.

Mr. Hogan is an employee of BGFA and BGI and has been one of the Portfolio
Managers primarily responsible for the day-to-day management of the Master
Portfolios since October 2008. Mr. Hogan has been a member of the asset
allocation portfolio management team since May 2007. Prior to becoming a
Portfolio Manager, Mr. Hogan was a derivatives trader with Credit Suisse from
2004 to 2006. From April 2002 through April 2004, Mr. Hogan was a currency
trader at BGI.

The LifePath Portfolios' SAI provides additional information about the
Portfolio Managers' compensation, other accounts managed by the Portfolio
Managers, and the Portfolio Managers' ownership of shares in the LifePath
Portfolios that invest in the Master Portfolios for which they are Portfolio
Managers.

ADMINISTRATIVE SERVICES

BGI provides the following services, among others, as the LifePath Portfolios'
administrator:

[] Supervise the LifePath Portfolios' administrative operations;

[] Provide or cause to be provided management reporting and treasury
administration services;

[] Financial reporting;

[] Legal, blue sky and tax services;

[] Preparation of proxy statements and shareholder reports; and

[] Engaging and supervising shareholder servicing agents (the "Shareholder
 Servicing Agents") on behalf of the LifePath Portfolios.

BGI is entitled to receive fees for these services at the annual rate of 0.50%
of the average daily net assets of the Class I Shares of each LifePath
Portfolio. In addition to performing these services, BGI has agreed to bear all
costs of operating the LifePath Portfolios, other than brokerage expenses,
advisory fees, distribution fees, certain fees and expenses related to the
LifePath Portfolios' Independent Trustees and their counsel, auditing fees,
litigation expenses, taxes or other extraordinary expenses.

The Shareholder Servicing Agents service individual and omnibus LifePath
Portfolio accounts pursuant to agreements with the LifePath Portfolios and/or
BGI. In addition to serving as agents of the LifePath Portfolios for purposes
of accepting orders for purchases and redemptions of LifePath Portfolio shares,
Shareholder Servicing Agents may provide administrative support and account
services such as processing purchases and redemptions of shares on behalf of
individual and omnibus LifePath Portfolio accounts, answering shareholder
inquiries, keeping records, transmitting reports and communications from the
LifePath Portfolios, and providing reports on the status of individual and
omnibus accounts. Shareholder Servicing Agents may provide these services, in
whole or in part, by operating electronic transaction systems or websites
through which shareholders may obtain information or engage in purchase or
redemption transactions of LifePath Portfolio shares. By operating these
systems or providing other services described above, the Shareholder Servicing
Agents make the LifePath Portfolios available to their clients.

BGI pays shareholder servicing fees to certain Shareholder Servicing Agents in
amounts not exceeding the maximum fee rates approved by the LifePath
Portfolios' Board of Trustees for those services that the Shareholder Servicing
Agents perform for their clients that would otherwise be performed by BGI or
the LifePath Portfolios' other service providers. In addition, BGFA and/or BGI
pay additional amounts to certain Shareholder Servicing Agents for more
services or to other intermediaries that perform services in connection with a
LifePath Portfolio's shares. These amounts, which may be significant, are paid
by BGFA and/or BGI from their own resources, which generally come directly or
indirectly from fees paid by funds advised by BGFA or administered by BGI. The
LifePath Portfolios' distributor may also pay certain Shareholder Servicing
Agents or intermediaries for such services from its own resources, which
generally come directly or indirectly from fees paid by BGI.

- --------------------------------------------------------------------------------
                                                                             27



A Shareholder Servicing Agent may make decisions about which investment options
it will service and make available to its clients based on the payments the
Shareholder Servicing Agent may be eligible to receive for its services.
Therefore, payments to a Shareholder Servicing Agent may create potential
conflicts of interest between the Shareholder Servicing Agent and its clients
where the Shareholder Servicing Agent determines which investment options it
will make available to those clients. Additional information regarding the
LifePath Portfolios' shareholder servicing arrangements can be found in the
LifePath Portfolios' SAI, which is available upon request.

Shareholder Information

WHO IS ELIGIBLE TO INVEST

To be eligible to purchase LifePath Portfolio Class I Shares, you must:

[] Invest through an employer-sponsored or individual retirement savings plan;

[] Invest the proceeds rolled over from such retirement savings plan into an
IRA;

[] Maintain an account with State Street Bank and Trust Company ("State
 Street"), the LifePath Portfolios' custodian, transfer agent and dividend
 disbursing agent, or with one of the LifePath Portfolios' Shareholder
 Servicing Agents; or

[] Initially invest a minimum of $1 million directly through State Street (in
 certain situations this minimum initial investment may be reduced or waived;
 please contact your Shareholder Servicing Agent or State Street for more
 information).

The LifePath Portfolios offer other classes of shares (Class R Shares and Class
S Shares) with different features and expense levels, which you may be eligible
to buy. Please see the LifePath Portfolios' Class R Shares and Class S Shares
prospectuses for more information.

In order to invest, a completed account application form must be submitted to,

account number assigned. You may be asked to provide information to verify your
identity when opening an account.

Your Shareholder Servicing Agent may charge you a fee and may offer additional
account services. Additionally, your Shareholder Servicing Agent may have
procedures for placing orders for Class I Shares that differ from those of the
LifePath Portfolios, such as different investment minimums or earlier trading
deadlines. Please contact your Shareholder Servicing Agent directly for more
information and details.

HOW TO BUY SHARES

[] PLAN PARTICIPANT. Invest through payroll deductions or make a direct
 contribution by rolling over an amount from another 401(k) plan or from a
 rollover IRA (make arrangements through your employer). If you are investing
 through a Shareholder Servicing Agent, your Shareholder Servicing Agent is
 responsible for properly transmitting your purchase order to State Street and
 may impose an earlier deadline than the LifePath Portfolios, as described
 below.

[] TAX-DEFERRED INVESTOR. Invest through a Shareholder Servicing Agent as
 provided in your benefit plan documents. Your Shareholder Servicing Agent,
 plan sponsor or administrator is responsible for properly transmitting your
 purchase order to State Street and may impose an earlier deadline for purchase
 and redemption orders than the LifePath Portfolios, as described below.

[] QUALIFIED BUYER. Invest through an account set up with State Street or your

[] DIRECT BUYER. See the "Special Instructions for Direct Buyers" section of
this Prospectus.

You may buy LifePath Portfolio shares without paying a sales charge. Your
purchase order must be received in proper form, as determined by State Street
or an intermediary pursuant to an appropriate agreement, by the close of
regular trading on the New York Stock Exchange ("NYSE") (generally 4:00 p.m.
Eastern Time) (or if regular trading on the NYSE closes early, at such closing
time) on any day the LifePath Portfolios are open (a "Business Day") to
purchase shares at that day's NAV. Orders received after the close of regular
trading on the NYSE will be executed on the next Business Day. The LifePath
Portfolios are generally open Monday through Friday and are generally closed on
weekends and any day on which the NYSE is closed.

Each LifePath Portfolio reserves the right to suspend or discontinue the offer
and sale of its shares and reject or cancel any purchase order for any reason.

Purchases generally must be made in U.S. dollars. You may be charged for any
costs incurred in connection with a purchase order that has been placed but for
which the LifePath Portfolio has not received full payment.

HOW TO SELL SHARES

[] PLAN PARTICIPANT AND TAX-DEFERRED INVESTOR. Contact your plan sponsor,
 administrator or Shareholder Servicing Agent. Your Shareholder Servicing Agent

You may sell LifePath Portfolio shares without paying a sales charge. Your
order to sell shares must be received in proper form, as determined by State
Street or an intermediary pursuant to an appropriate agreement, by the close of
regular trading on the NYSE (generally 4:00 p.m. Eastern Time) (or if regular

sell shares at that day's NAV. Orders received after the close of regular
trading on the NYSE will be executed on the next Business Day.

The LifePath Portfolios generally remit the proceeds from a sale the next
Business Day after receiving a properly executed order to sell and no longer
than seven days after the sale. Each LifePath Portfolio reserves the right to
suspend your right of redemption and to delay delivery of your redemption
proceeds up to seven days, as permitted under applicable law. Each LifePath
Portfolio further reserves the right to automatically redeem your shares and
close your account for any reason, subject to applicable law, and send you the
proceeds, which would reflect the NAV on the day the LifePath Portfolio
automatically redeems your shares. For example, a LifePath Portfolio may
automatically redeem your shares to reimburse the LifePath Portfolio for any
losses sustained by reason of your failure to make full payment for shares
purchased or to collect any charge relating to a transaction effected for your
benefit that is applicable to the LifePath Portfolio's shares as provided from
time to time in this Prospectus.

In addition, each LifePath Portfolio reserves the right to send your redemption
proceeds in the form of securities from its Master Portfolio.

Upon redemption, the identity of the holder of the account to which the
proceeds are being sent may need to be verified.

CALCULATING THE LIFEPATH PORTFOLIOS' SHARE PRICE

Each LifePath Portfolio's share price (also known as a LifePath Portfolio's
NAV) is calculated by dividing the value of the net assets of the LifePath
Portfolio (I.E., the value of its total assets less total liabilities) by the
total number of outstanding shares of the LifePath Portfolio, generally rounded
to the nearest cent.

Each LifePath Portfolio's NAV is calculated at the close of regular trading on
the NYSE (generally, 4:00 p.m. Eastern Time) on any Business Day. If regular
trading on the NYSE closes early, the time for calculating each LifePath
Portfolio's NAV and the deadline for share transactions will be accelerated to
the earlier closing time. The NAV of each LifePath Portfolio is calculated
based on the net asset value of the Master Portfolio in which the LifePath
Portfolio invests. The LifePath Portfolios' SAI includes a description of the
methods for valuing the Master Portfolios' investments, including a

- --------------------------------------------------------------------------------
     30                                        BARCLAYS GLOBAL INVESTORS FUNDS



description of the circumstances in which the Master Portfolios' investments
would be valued using fair value pricing and the effects of using fair value
pricing.

LIFEPATH PORTFOLIO DISTRIBUTIONS

The LifePath Portfolios distribute their net investment income to shareholders
quarterly. The LifePath Portfolios distribute their net realized capital gains,
if any, to shareholders at least annually. Distributions payable to you will be
automatically reinvested in additional Class I Shares of your LifePath
Portfolio, unless you have elected to receive distribution payments in cash.

FREQUENT TRADING IN LIFEPATH PORTFOLIO SHARES

Frequent purchases and redemptions of mutual fund shares ("frequent trading")
may have a detrimental effect on a fund and its shareholders. Depending on
various factors, such as the size of the fund's investment portfolio and the
amount of assets maintained in cash, frequent trading may harm the performance
of the fund by interfering with the implementation of its investment strategies
and/or increasing transaction costs and taxes, and/or may dilute the value of
fund shares held by long-term investors. Frequent trading may include activity
that appears to attempt to take advantage of a potential arbitrage opportunity
presented by a lag between a change in the value of a fund's investment
portfolio securities after the close of the primary markets for those portfolio
securities and the reflection of that change in the fund's net asset value
("market timing").

Each LifePath Portfolio invests only in interests of its Master Portfolio, and
the Boards of Trustees of the Master Portfolios and the LifePath Portfolios
have each considered the issues of frequent trading and market timing.

The Master Portfolios' Board of Trustees has adopted a policy of not monitoring
for possible market timing activity because the Master Portfolios' holdings are
valued as of the same time that the net asset value of the Master Portfolios is
calculated (generally 4:00 p.m. Eastern Time), which eliminates the potential
arbitrage opportunity presented by a lag between a change in the value of the
Master Portfolios' holdings and the reflection of that change in the Master
Portfolios' respective net asset values. The Master Portfolios' Board of
Trustees has not adopted a policy of monitoring for other forms of frequent
trading because daily flows into and out of the Master Portfolios are
aggregated, and the process of aggregation is expected to reduce the potential
for frequent trading to disrupt the implementation of the Master Portfolios'
investment strategies.

The LifePath Portfolios' Board of Trustees has not adopted a policy of
monitoring for market timing or other frequent trading activity in the LifePath
Portfolios in light of the nature of the LifePath Portfolios' investment in
Master Portfolios, the policies of the Master Portfolios, as described in the
preceding paragraphs, and the historical nature of flows into and out of the
LifePath Portfolios.

BGI's ability to monitor trades that are placed by participants in plans that
are shareholders in the LifePath Portfolios or other shareholders in the
LifePath Portfolios that trade through omnibus accounts maintained by
intermediaries will be severely limited to the extent BGI does not receive
transaction information showing individual investment decisions. Upon request
by the LifePath Portfolios, intermediaries are required to provide certain
transaction information that may enable the LifePath Portfolios to identify
trading activity that is potentially harmful to the LifePath Portfolios. The
LifePath Portfolios may, but do not have the obligation to, respond to any
potentially harmful trading activity that is identified. In the event any
potentially harmful trading activity is identified, responses may include the
imposition of trading restrictions, the rejection of purchases, or such other
steps the LifePath Portfolios determine are appropriate. Intermediaries'
ability to impose restrictions on the trading practices of their clients may,
however, be affected by legal or technological limitations.

TAXES

The following discussion regarding U.S. federal income taxes is based upon laws
in effect as of the date of this Prospectus and summarizes only some of the
important U.S. federal income tax considerations affecting the LifePath
Portfolios and their U.S. shareholders. This discussion is not intended as a
substitute for careful tax planning. Please see the SAI for additional U.S.
federal income tax information.

- --------------------------------------------------------------------------------
                                                                             31



Distributions from your LifePath Portfolio's net investment income and net
realized capital gains are taxable, whether you choose to receive them in cash
or automatically reinvest them in additional LifePath Portfolio shares. The
amount of taxes you owe will vary depending on your tax status and on your tax
rate and the amount and character of the LifePath Portfolio's distributions to
you. Normally, distributions are taxable to you when paid. However, when
distributions are declared in the last three months of a year and paid in
January of the next year, they are taxable as if paid on December 31 of the
prior year.

Distributions from the LifePath Portfolios generally are taxable as follows:



DISTRIBUTION TYPE             TAX STATUS
- ---------------------------   --------------------------------
                           
Qualified dividend
  income...................   Qualified dividend income(1)(2)
Other income...............   Ordinary income(2)
Short-term capital gain....   Ordinary income
Long-term capital gain.....   Long-term capital gain(3)


- -------
  (1)   If you are an individual, your distributions attributable to the
        LifePath Portfolio's qualified dividend income generally are taxable to
        you at a maximum 15% U.S. federal income tax rate, as long as you meet
        certain holding period and other requirements. Qualified dividend
        income is, in general, dividend income received from taxable U.S. and
        certain foreign corporations. Absent further legislation, the reduced
        rates of tax for qualified dividend income will expire after December
        31, 2010.
  (2)   A portion of distributions paid to corporate shareholders of the
        LifePath Portfolios may qualify for the dividends-received deduction
        available to corporations.
  (3)   An individual's net long-term capital gain currently is subject to a
        reduced maximum 15% U.S. federal income tax rate. Absent further
        legislation, this reduced 15% maximum tax rate on long-term capital
        gain is scheduled to expire after December 31, 2010.

In addition, if you sell your LifePath Portfolio shares you generally will have
a taxable capital gain or loss in an amount equal to the difference between the
net amount of sale proceeds that you receive and your tax basis for the shares
that you sell. In certain circumstances, a loss on the sale may be disallowed:



TRANSACTION                   TAX STATUS
- ---------------------------   --------------------------------
                           
You sell shares owned
for more than one year ....   Long-term capital gain or loss
You sell shares owned
for one year or less ......   Short-term capital gain or loss


If you buy a LifePath Portfolio's shares shortly before it makes a
distribution, you will, in effect, receive part of your purchase back in the
form of a taxable distribution. Similarly, if you buy shares of a LifePath
Portfolio that holds appreciated securities, you will, in effect, receive part
of your purchase back in a taxable distribution if and when the LifePath
Portfolio sells the appreciated securities and distributes the realized gain on
the sale. The LifePath Portfolios have built up, or have the potential to build
up, high levels of unrealized appreciation in their investments.

After the end of each year, the LifePath Portfolios will send to you a notice
that tells you how much you have received in distributions during the year and
their U.S. federal income tax status. You could also be subject to foreign,
state and local taxes on such distributions.

In certain circumstances, you may be subject to back-up withholding taxes on
distributions to you from the LifePath Portfolios if you fail to provide the
LifePath Portfolios with your correct social security number or other taxpayer
identification number, or to make required certifications, or if you have been
notified by the Internal Revenue Service that you are subject to back-up
withholding.

TAX CONSIDERATIONS FOR TAX-EXEMPT OR FOREIGN INVESTORS OR THOSE HOLDING
LIFEPATH PORTFOLIO SHARES THROUGH A TAX-DEFERRED ACCOUNT, SUCH AS A 401(K) PLAN
OR IRA, WILL BE DIFFERENT. FOR EXAMPLE, SHAREHOLDERS THAT ARE EXEMPT FROM U.S.
FEDERAL INCOME TAX, SUCH AS RETIREMENT PLANS THAT ARE QUALIFIED UNDER SECTION
401 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED, GENERALLY ARE NOT SUBJECT
TO U.S. FEDERAL INCOME TAX ON LIFEPATH PORTFOLIO DIVIDENDS OR DISTRIBUTIONS OR
ON SALES OF LIFEPATH PORTFOLIO SHARES. BECAUSE EACH INVESTOR'S TAX
CIRCUMSTANCES ARE UNIQUE AND BECAUSE TAX LAWS ARE SUBJECT TO CHANGE, YOU SHOULD
CONSULT YOUR TAX ADVISOR ABOUT YOUR INVESTMENT.

MASTER/FEEDER MUTUAL FUND STRUCTURE

The LifePath Portfolios do not have their own investment adviser. Instead, each
LifePath Portfolio invests all of its assets in a separate mutual fund, called
a Master Portfolio, that has a substantially identical investment objective,
strategies and policies as the LifePath Portfolio. BGFA serves as investment
adviser to each Master Portfolio. The Master Portfolios may accept investments
from other feeder funds. Certain actions involving other feeder funds, such as
a substantial withdrawal, could affect the Master Portfolios and, therefore,
the LifePath Portfolios.

FEEDER FUND EXPENSES

Feeder funds, including the LifePath Portfolios, bear their respective Master
Portfolio's expenses in proportion to the amount of assets each invests in the
Master Portfolio. Each feeder fund can set its own transaction minimums,
fund-specific expenses and conditions.

FEEDER FUND RIGHTS

Under the master/feeder structure, the LifePath Portfolios' Board of Trustees
retains the right to withdraw a LifePath Portfolio's assets from its Master
Portfolio if it believes doing so is in the best interests of the LifePath
Portfolio's shareholders. If the Board of Trustees decides to withdraw a
LifePath Portfolio's assets, it would then consider whether the LifePath
Portfolio should hire its own investment adviser, invest in another master
portfolio or take other action.

FUND OF FUNDS

The Master Portfolios do not invest directly in a portfolio of securities.
Instead, they invest in the Underlying Money Market Fund and other Underlying
Funds that are also advised by BGFA. Each Master Portfolio charges for its own
direct expenses, in addition to bearing a PRO RATA share of the expenses
charged by the Underlying Funds in which it invests.

Financial Highlights

The financial tables in this section are intended to help investors understand
the financial performance of the Class I Shares of each LifePath Portfolio for
the past five years or, if shorter, the period of the LifePath Portfolio's
operations. Certain information reflects financial results for a single Class I
Share of each LifePath Portfolio. The total returns in the tables represent the
rate of return that an investor would have earned (or lost) on an investment in
Class I Shares of a given LifePath Portfolio, assuming reinvestment of all
distributions. The information has been audited by PricewaterhouseCoopers LLP,
whose report, along with the LifePath Portfolios' financial statements, is
included in the LifePath Portfolios' annual report. You may obtain copies of

Overview

INTRODUCTION

The LifePath Portfolios/1/ are designed to offer individual investors
comprehensive asset allocation strategies tailored to the time when they expect
to begin withdrawing assets. Asset allocation is the distribution of
investments among broad types of asset classes: equity securities, bonds and
money market instruments. Each LifePath Portfolio invests all of its assets in
a separate mutual fund, called a Master Portfolio, that has a substantially
identical investment objective as the LifePath Portfolio. To implement the
asset allocation strategy, each Master Portfolio, in turn, invests in a
combination of equity securities, bond and money market funds (the "Underlying
Funds") in proportions based on its own comprehensive investment strategy that
gradually becomes more conservative as the year in the LifePath Portfolio's
name approaches, except for the LifePath Retirement Portfolio, which is already
in its most conservative phase. Barclays Global Fund Advisors ("BGFA") is the
investment adviser to the Master Portfolios.

WHICH LIFEPATH PORTFOLIO TO CONSIDER

The first step in choosing which LifePath Portfolio to consider is answering a
key question: When will you need the money you are thinking of investing? Will
it be in ten years, when your kids are ready for college? Or 30 years, when you
retire?

The number in the name of most of the LifePath Portfolios is actually a year -
a "target year" when you might expect to begin withdrawing your money.
Selecting the LifePath Portfolio that may be most appropriate for your
investment may be as simple as matching your target year with the closest
LifePath Portfolio target year.

For example, let's say that you are investing for retirement purposes, and that
you expect to retire at age 60. If you are 45 years old, you have 15 years
before retirement. By adding 15 to the current year, you can define your
"target year." If you expect to retire in the year 2023, as in this example,
you may conclude that the LifePath 2020 Portfolio is the most appropriate
LifePath Portfolio for you.

(1)For simplicity's sake, all discussion of investment objective, strategies
   and risks of a particular LifePath Portfolio refers also to the investment
   objective, strategies and risks of the Master Portfolio, unless otherwise
   indicated. A detailed description of the relationship of the LifePath
   Portfolios to their Master Portfolios appears under the heading
   "Shareholder Information - Master/Feeder Mutual Fund Structure" in this
   Prospectus.

LIFEPATH(Reg. TM) PORTFOLIOS - HOW THEY WORK

[GRAPHIC APPEARS HERE]

NOTE: THE ABOVE CHART IS FOR ILLUSTRATIVE PURPOSES ONLY AND DOES NOT REPRESENT
THE ACTUAL ALLOCATION PERCENTAGES OF THE LIFEPATH PORTFOLIOS.

The chart shows that over time, the investment mix of each LifePath Portfolio
gradually shifts from a greater concentration of higher-risk investments
(namely, equity securities funds) to a greater concentration of lower-risk
investments (namely, bond funds), thereby making the LifePath Portfolio
increasingly conservative.

In making your investment decision, you should keep in mind:

[] Each LifePath Portfolio's investment strategy derives from the risk
 tolerance of average investors with a particular time horizon.

[] Each LifePath Portfolio's time horizon is based on the year in its name,
 except for the LifePath Retirement Portfolio, which is designed for investors
 who are currently withdrawing, or plan in the near future to begin
 withdrawing, a substantial portion of their investment.

If you are willing to accept a greater risk of short-term loss in exchange for
the potential to achieve higher long-term returns, you may invest some or all
of your assets in a LifePath Portfolio with a longer time horizon. If you
desire a more conservative investment and are willing to forego some potential
returns, you may invest some or all of your assets in a LifePath Portfolio with
a shorter time horizon. The final choice is yours.

Investment Objectives

Each LifePath Portfolio seeks to maximize return consistent with the
quantitatively measured risk that investors on average may be willing to accept
given their investment time horizon. An investor's time horizon marks the point
when the investor plans to start making net withdrawals from his or her
investments. As a general rule, investors with a longer time horizon have a
greater tolerance for risk than investors with a shorter time horizon.
Long-term investors are more likely to accept a greater risk of short-term loss
in exchange for the potential to achieve higher long-term returns. Each
LifePath Portfolio has its own time horizon, which affects the targeted risk
level of the LifePath Portfolio and, in turn, its asset allocation.

SPECIFICALLY:

[] LifePath Retirement Portfolio is managed for investors seeking income and
moderate long-term growth of capital.

[] LifePath 2010 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2010.

[] LifePath 2020 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2020.

[] LifePath 2030 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2030.

[] LifePath 2040 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2040.

[] LifePath 2050 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2050.

Each LifePath Portfolio's investment objective may be changed by the LifePath
Portfolio's Board of Trustees without shareholder approval.

Summary of Principal Investment Strategies
Each LifePath Portfolio invests all of its assets in a corresponding Master
Portfolio which allocates and reallocates its assets among the Underlying
Funds. The Master Portfolios with longer time horizons invest a greater portion
of their assets in Underlying Funds that invest in equity securities, which
provide a greater opportunity for capital appreciation over the long-term but
have a greater risk of short-term loss. The Master Portfolios with shorter time
horizons invest a greater portion of their assets in Underlying Funds that
invest in bonds and money market instruments, which typically offer reduced
risk and price volatility but forego some potential returns. Accordingly, under
normal circumstances, the LifePath Portfolios with shorter time horizons have
lower expected returns than the LifePath Portfolios with longer time horizons.

[] LifePath Retirement Portfolio is designed for investors seeking current
 income and moderate long-term growth of capital. As of March 31, 2009, the
 LifePath Retirement Portfolio held approximately 38% of its assets in
 Underlying Funds that invest primarily in equity securities, 62% of its assets
 in Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 Because the LifePath Retirement Portfolio is in its most conservative phase,
 its allocation generally does not become more conservative over time, although
 its allocation may change to maintain the LifePath Retirement Portfolio's risk
 profile.

[] LifePath 2010 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2010. As of March 31, 2009, the
 LifePath 2010 Portfolio held approximately 40% of its assets in Underlying
 Funds that invest primarily in equity securities, 60% of its assets in
 Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 As the stated time horizon approaches, the allocation will become more
 conservative and have lower expected returns.

[] LifePath 2020 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2020. As of March 31, 2009, LifePath
 2020 Portfolio held approximately 61% of its assets in Underlying Funds that
 invest primarily in equity securities, 39% of its assets in Underlying Funds
 that invest primarily in bonds and the remainder of its assets in Underlying
 Funds that invest primarily in money market instruments. As the stated time
 horizon approaches, the allocation will become more conservative and have
 lower expected returns.

[] LifePath 2030 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2030. As of March 31, 2009, the
 LifePath 2030 Portfolio held approximately 76% of its assets in Underlying
 Funds that invest primarily in equity securities, 24% of its assets in
 Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 As the stated time horizon approaches, the allocation will become more
 conservative and have lower expected returns.

[] LifePath 2040 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2040. As of March 31, 2009, the
 LifePath 2040 Portfolio held approximately 89% of its assets in Underlying
 Funds that invest primarily in equity securities, 11% of its assets in
 Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 As the stated time horizon approaches, the allocation will become more
 conservative and have lower expected returns.

[] LifePath 2050 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2050. As of March 31, 2009, the
 LifePath 2050 Portfolio held approximately 99% of its assets in Underlying
 Funds that invest primarily in equity securities, 1% of its assets in
 Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 As the stated time horizon approaches, that allocation will become more
 conservative and have lower expected returns.

When a LifePath Portfolio reaches its stated time horizon and enters its most
conservative phase - E.G., the LifePath 2010 Portfolio - the allocation of its
assets is expected to be similar to that of the LifePath Retirement Portfolio.
Such LifePath Portfolio and the LifePath Retirement Portfolio may then continue
to operate as separate funds or, subject to approval by the LifePath
Portfolios' Board of Trustees, they may be merged into a single fund.

Summary of Principal Risk Factors

As with any investment, your investment in the LifePath Portfolios could lose
money or the Portfolios' performance could trail that of other investments.

EACH LIFEPATH PORTFOLIO HAS A DIFFERENT LEVEL OF RISK.

The value of your investment is subject to equity securities market risk, which
means the price of the equity securities in which the Underlying Funds invest
may fluctuate or fall in response to economic events or trends.

The value of your investment is also subject to bond investment risks,
including interest rate risk, which means that the prices of bonds in which the
Underlying Funds invest may fall because of a rise in interest rates; credit
risk, which is the risk that the price of an individual bond may fall with the
decline in an issuer's real or apparent ability to meet its financial
obligations; extension risk, which is the risk that borrowers may extend the
prepayment of their mortgages or loans for longer periods than expected,
thereby affecting the security's average life and, potentially, its yield; and
prepayment risk, which is the risk that borrowers may prepay their mortgages or
loans faster than expected, thereby affecting the security's average life and,
potentially, its yield. The risk of default and price volatility of high yield
securities is greater than the risk usually associated with higher-rated
securities.

Investments in foreign securities by the Underlying Funds are subject to
certain special risks and considerations, including potentially less liquidity
and greater price volatility than investments in securities traded in the U.S.
markets. These risks are greater for investments in foreign securities issued
by companies or sovereign entities in emerging market countries.

The allocation of each LifePath Portfolio's assets is managed using a
quantitative model that has been developed based on a number of factors.
Neither the LifePath Portfolios nor BGFA can offer any assurance that the
recommended asset allocation will either maximize returns or minimize risk or
be the appropriate allocation in all circumstances for every investor with a
particular time horizon.

The value of your investment is also subject to passive investment risk,
security selection risk and concentration risk. Because BGFA does not select
individual companies in the underlying indexes for certain Underlying Funds,
those Underlying Funds may hold stocks in companies that present risks that an
adviser researching individual stocks might seek to avoid. This is known as
passive investment risk. In the case of the Underlying Funds where BGFA does
select securities based on its analysis, these funds are subject to the risk
that security selection will contribute to underperformance. Concentration risk
is the risk that an Underlying Fund that concentrates in a single industry or
group of industries may be more susceptible to any single economic, market,
political or regulatory occurrence in that industry or group of industries.

The value of your investment is subject to real estate investment risk, which
includes many of the same risks associated with the direct ownership of real
estate.

Investments in derivatives by certain Underlying Funds are subject to special
risks and considerations. Derivatives are financial instruments whose values
are derived, at least in part, from the prices of other securities or specified
assets, indexes or rates.

Certain Underlying Funds are also subject to market trading risks due to their
shares being listed and traded on securities exchanges (including potential
halts in trading or a fluctuation in trading price in accordance with changes
in net asset value), and tracking error risk, in that the return of an
Underlying Fund that seeks to track an index may deviate from the return of
such index.

- --------------------------------------------------------------------------------
                                                                              5



The LifePath Portfolios must maintain cash balances to meet redemption
requests, which may lower overall portfolio performance.

An investment in a LifePath Portfolio is not a bank deposit and it is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

Investment Returns

TOTAL RETURNS

The bar charts and table in this section provide some indication of the risks
of investing in the LifePath Portfolios by showing the changes in their
performance from year to year. The bar charts show the returns for Class R of
each LifePath Portfolio for each of the last ten calendar years./1/ The average
annual total return table compares the average annual total returns (before and
after taxes) of Class R of each LifePath Portfolio to those of a corresponding
index for various periods of time. Effective March 15, 2004, the returns for
each LifePath Portfolio reflect its Master Portfolio's investment in Underlying
Funds. For all periods prior to March 15, 2004, the returns for each LifePath
Portfolio reflect the direct investment by its Master Portfolio in a portfolio
of securities and also reflect investment in accordance with a model that
included "tactical," or short-term, shifts in allocation between stocks and
bonds. In addition, as of December 31, 2003, BGFA made certain changes to its
asset allocation strategies for the LifePath Portfolios, including a change to
the frequency with which the LifePath Portfolios' respective holdings were
rebalanced among asset classes from monthly to quarterly.

How the LifePath Portfolios performed in the past (before and after taxes) is
not necessarily an indication of how they will perform in the future.

  (1)   Performance shown for the periods prior to April 30, 2001 (the date
        the Class R Shares commenced operations) reflects the performance of
        the Class I Shares adjusted to reflect the fees and expenses of the
        Class R Shares. Performance from April 30, 2001 reflects the actual
        performance of Class R Shares. Effective May 1, 2005, Class R Shares
        are sold without any sales charges. Effective March 15, 2004, the
        returns for each LifePath Portfolio reflect its Master Portfolio's
        investment in Underlying Funds. For all periods prior to March 15,
        2004, the returns for each LifePath Portfolio reflect the direct
        investment by its Master Portfolio in a portfolio of securities and
        also reflect investment in accordance with a model that included
        "tactical," or short-term, shifts in allocation between stocks and
        bonds. In addition, as of December 31, 2003, BGFA made certain changes
        to its asset allocation strategies for the LifePath Portfolios,
        including a change to the frequency with which the LifePath Portfolios'
        respective holdings were rebalanced among asset classes from monthly to
        quarterly.

        not reflect the impact of state, local or foreign taxes. Actual
        after-tax returns depend on an investor's tax situation and may differ
        from those shown, and after-tax returns shown are not relevant to
        tax-exempt investors or investors who hold shares through tax-deferred
        arrangements, such as 401(k) plans or individual retirement accounts
        ("IRAs"). A LifePath Portfolio's returns after taxes on distributions
        and sale of LifePath Portfolio shares are calculated assuming that an
        investor has sufficient capital gains of the same character from other
        investments to offset any capital losses from the sale of LifePath
        Portfolio shares. As a result, a LifePath Portfolio's returns after
        taxes on distributions and sale of LifePath Portfolio shares may exceed
        the LifePath Portfolio's returns before taxes and/or returns after
        taxes on distributions.

        included in the LifePath Portfolios' custom benchmarks are adjusted
        quarterly to reflect the LifePath Portfolios' changing asset
        allocations over time. As of December 31, 2008, the following indexes
        are used to calculate the LifePath Portfolios' custom benchmarks: S&P

        ex US IMI Index replaced the MSCI All Country World Index ex USA Index
        on July 1, 2008. The FTSE EPRA/NAREIT Global Real Estate Index replaced
        the Cohen & Steers Realty Majors Index on July 1, 2008.

  (6)   Effective November 3, 2008, the names of the noted indexes changed
        from the Lehman Brothers U.S. Aggregate Index and Lehman Brothers U.S.
        Treasury TIPS Index to the Barclays Capital U.S. Aggregate Bond Index
        and Barclays Capital U.S. Treasury Inflation Protected Securities
        (TIPS) Index (Series-L), respectively. Changes to these indexes are
        discussed further on page 21.

BGFA and BGI have in the past waived and may from time to time agree to waive
all or a portion of their fees or reimburse expenses to a Master Portfolio or
LifePath Portfolio. When they do so, the applicable LifePath Portfolio's
operating expenses are reduced so that the LifePath Portfolio's total return is
increased. These waivers and reimbursements may be discontinued at any time,
except as described in footnotes 1 and 2 to the Fees and Expenses table on the
immediately following page. In the absence of such waivers and/or
reimbursements, the applicable LifePath Portfolio's total return would be
lower.

Fees and Expenses

The table below describes the fees and expenses that you may pay if you buy and
hold Class R Shares of a LifePath Portfolio. The expenses are deducted from
each LifePath Portfolio's assets, which means you pay them indirectly. This
table does not reflect charges that may be imposed in connection with an
account in which you hold the shares. A broker-dealer or financial institution
maintaining the account in which you hold shares may charge a separate account,
service or transaction fee on the purchase or sale of Class R Shares that would
be in addition to the fees and expenses shown here.

The total annual operating expense ratios in the table and the example on the
next page reflect the expenses of the Class R Shares of each LifePath Portfolio
and its corresponding Master Portfolio and also reflect a weighted average of
the total operating expense ratios of the Underlying Funds in which each Master
Portfolio invests:

EXAMPLE

The example below is intended to help you compare the cost of investing in
Class R Shares of the LifePath Portfolios with the cost of investing in other
mutual funds. The example illustrates the cost you would have incurred on an
initial $10,000 investment in Class R Shares of each LifePath Portfolio over
the time periods shown. It assumes your investment earns an annual return of 5%
over the periods, that total operating expenses remain the same and that the
contractual fee waivers and reimbursements by BGFA and BGI are in effect for
two years.

THE LIFEPATH PORTFOLIOS DO NOT CHARGE A SALES LOAD OR OTHER FEE UPON
REDEMPTION. This means that your cost for each period would be the same whether
or not you sell your shares at the end of a period. Your actual costs may be
higher or lower than this hypothetical example:

A Further Discussion of Principal Investment Strategies

INTRODUCTION

Each LifePath Portfolio pursues a common strategy of allocating and
reallocating its assets among the Underlying Funds. The LifePath Portfolios
with longer time horizons invest a greater portion of their assets in
Underlying Funds that invest in equity securities, which provide a greater
potential to achieve higher returns over the long-term but have a greater risk
of short-term loss. In addition to investing in Underlying Funds, each LifePath
Portfolio may borrow, lend its portfolio securities to brokers, dealers and
financial institutions, and may invest the collateral in certain short-term
instruments either directly or through one or more joint accounts or money
market funds, as described in greater detail in the LifePath Portfolios'
combined Statement of Additional Information ("SAI").

The LifePath Portfolios with shorter time horizons invest a greater portion of
their assets in Underlying Funds that invest in bonds and money market
instruments, which typically offer reduced risk and price volatility, but
forego some potential returns. Accordingly, under normal circumstances, the
LifePath Portfolios with shorter time horizons have lower expected returns than
the LifePath Portfolios with longer time horizons. As each LifePath Portfolio
approaches its designated time horizon, it systematically seeks to reduce the
level of risk by allocating assets more conservatively among the Underlying
Funds. This systematic shift toward more conservative investments is designed
to reduce the risk of significant reductions in the value of an investment in a
LifePath Portfolio as it approaches its time horizon.

For example, the LifePath Retirement Portfolio has entered its "retirement
phase" and seeks to maximize returns consistent with the risk that an average
investor in retirement may be willing to accept. This does not mean, however,
that it invests exclusively, or primarily, in Underlying Funds that are money
market funds. Rather, because BGFA believes that most investors are still
willing to take some risks in pursuing returns even while drawing on their
investments, a portion of the LifePath Retirement Portfolio's assets will
continue to be allocated to Underlying Funds that are equity and bond funds, in
addition to Underlying Funds that are money market funds.

In determining the allocation of assets to the Underlying Funds, BGFA uses a
proprietary investment model that analyzes securities market data, including
risk, asset class correlations, and expected returns, to provide portfolio
allocations among the asset classes represented by the Underlying Funds. The
allocations are periodically monitored and rebalanced in an effort to maximize
expected return for a given level of risk. In managing the LifePath Portfolios,
BGFA focuses on long-term targets and objectives. The progression over time of
a LifePath Portfolio's asset allocation to more conservative asset classes is a
relatively steady process resulting in only gradual changes to the asset
allocation from quarter to quarter. The Underlying Funds invest in a mix of
equity securities, bonds and money market instruments. Certain Underlying Funds
invest in real estate investment trusts ("REITs"), foreign securities, emerging
markets, below investment-grade bonds and derivatives, which are subject to
additional risks, as described in the "Further Discussion of Principal Risk
Factors" section of this Prospectus. The investment model adjusts each LifePath
Portfolio's risk level by gradually making it more conservative as the year in
the LifePath Portfolio's name approaches, except for the LifePath Retirement
Portfolio, which is already in its most conservative phase.

THE UNDERLYING FUNDS

Two of the Underlying Funds - the Active Stock Master Portfolio and the
CoreAlpha Bond Master Portfolio (collectively, the "Underlying Master
Portfolios") - are diversified portfolios of Master Investment Portfolio
("MIP"). The Active Stock Master Portfolio seeks to provide long-term
appreciation of capital. BGFA invests the Active Stock Master Portfolio's
assets using a proprietary quantitative model that is designed to select stocks
based on an analysis of a wide range of company-specific factors. The CoreAlpha
Bond Master Portfolio seeks to provide a combination of income and capital
growth. BGFA invests the CoreAlpha Bond Master Portfolio's assets pursuant to a
systematic method that relies on

- --------------------------------------------------------------------------------
                                                                             13



proprietary quantitative models to allocate assets among various bond sectors
by evaluating each sector's relative value and risk-adjusted return.

The remaining Underlying Funds, other than the Barclays Global Investors Funds
("BGIF") Institutional Money Market Fund (the "Underlying Money Market Fund")
are exchange-traded funds ("ETFs") that are part of the iShares family of funds
("Underlying iShares Funds"). Each of the Underlying iShares Funds seeks
investment results that correspond generally to the performance, before fees
and expenses, of its underlying index. As a result, adverse performance of a
particular security in an Underlying iShares Fund's portfolio will ordinarily
not result in the elimination of the security from the Underlying iShares
Fund's portfolio. Each Underlying iShares Fund offers and issues iShares at
their net asset value per share only to certain institutional investors in
aggregations of a specified number of iShares, generally in exchange for a
basket of securities included in its underlying index, together with the
deposit of a specified cash payment. The iShares for these Underlying iShares
Funds are listed and traded on national securities exchanges and also may be
listed on certain non-U.S. exchanges. BGFA purchases iShares on behalf of the
Master Portfolios in the secondary market.

The relative weightings for each Master Portfolio in the various Underlying
Funds will vary over time, and BGFA is not required to invest any Master
Portfolio's assets in each of the Underlying Funds or in any particular
percentage in any given Underlying Fund. BGFA may add, eliminate or replace
Underlying Funds at any time.

Each Master Portfolio currently expects to invest in some or all of the
Underlying Funds described below:

ACTIVE STOCK MASTER PORTFOLIO

Seeks to provide long-term appreciation of capital. The Active Stock Master
Portfolio invests, under normal circumstances, at least 80% of its assets in
common stocks. The Active Stock Master Portfolio invests primarily in equity
securities of U.S. companies with market capitalizations similar to the range
of market capitalizations represented in the Standard & Poor's S&P 500 Index.
BGFA invests the Active Stock Master Portfolio's assets using a proprietary
quantitative model that is designed to select stocks based on an analysis of a
wide range of company-specific factors, such as relative values based on
earnings and cash flows; earnings quality as measured by the company's
financial condition and earnings reports; sentiment as expressed through
management and market participant behavior; and industry classification. BGFA
considers risk parameters in deciding upon the Active Stock Master Portfolio's
aggregate holdings, and factors trading costs into its stock selection process.


COREALPHA BOND MASTER PORTFOLIO

Seeks to provide a combination of income and capital growth. BGFA invests the
CoreAlpha Bond Master Portfolio's assets pursuant to a systematic method that
relies on proprietary quantitative models to allocate assets among various bond
sectors by evaluating each sector's relative value and risk-adjusted return.
BGFA's models also allocate assets among bonds of different maturities based on
yield characteristics and expectations. Specific investment selection decisions
are made on the basis of evaluations of relative value, credit quality and
other factors. The CoreAlpha Bond Master Portfolio invests, under normal
circumstances, at least 80% of its assets in bonds. For the purposes of this
strategy, "bonds" include the following: obligations issued or guaranteed by
the U.S. government, its agencies or instrumentalities; mortgage-backed
securities issued or guaranteed by the U.S. government, its agencies or
instrumentalities, including U.S. agency mortgage pass-through securities;
commercial mortgage-backed securities; debt obligations of U.S. corporations;
dollar-denominated debt obligations of foreign issuers; municipal securities;
and asset-backed securities. The CoreAlpha Bond Master Portfolio invests a
substantial portion of its assets in U.S.-registered, dollar-denominated bonds.
The CoreAlpha Bond Master Portfolio may invest in bonds of any maturity or
duration.

BGIF INSTITUTIONAL MONEY MARKET FUND

Seeks a high level of income consistent with liquidity and the preservation of
capital. The BGIF Institutional Money Market Fund invests in high-quality,

factors such as market capitalization and industry weightings), fundamental
characteristics (such as return variability, duration, maturity or credit

underlying index. Underlying iShares Funds that use representative sampling may

A Further Discussion of Principal Risk Factors

In addition to the principal risks of investing described in the "Summary of
Principal Risk Factors" section of this Prospectus, the LifePath Portfolios
have the following risks:

GENERAL

The net asset value of each LifePath Portfolio's shares ("NAV") is neither
insured nor guaranteed, is not fixed and will fluctuate.

GENERAL RISKS APPLICABLE TO THE LIFEPATH PORTFOLIOS

EQUITY SECURITIES MARKET RISKS

The risks of investing in the equity securities market include both short-term
and prolonged price declines. The value of an equity security may decline in
value due to factors affecting equity securities markets generally or
particular industries represented in the markets. Equity securities may
underperform fixed-income investments and securities market indexes that track
other markets, segments and sectors. Equity securities of mid- to small-cap
companies tend to present greater risks than equity securities of large-cap
companies because they are generally more volatile and can be less liquid.

BOND INVESTMENT RISKS

The risks of fixed-income investing include short-term and prolonged price
declines because of a rise in interest rates, issuer quality considerations and
other economic considerations; however, such price declines in the bond market
have historically been less severe than stock declines.

CREDIT RISK

Credit risk is the risk that issuers or guarantors of debt instruments or the
counterparty to a derivatives contract, repurchase agreement or loan of
portfolio securities is unable or unwilling to make timely interest and/or
principal payments or to otherwise honor its obligations. There is the chance
that any of an Underlying Fund's holdings will have their credit ratings
downgraded or will default (fail to make scheduled interest or principal
payments), potentially reducing an Underlying Fund's income level and share
price. Debt instruments are subject to varying degrees of credit risk, which
may be reflected in credit ratings. Securities issued by the U.S. government
have limited credit risk. However, securities issued by U.S. government
agencies (such as U.S. agency mortgage pass-through securities) are not
necessarily backed by the full faith and credit of the U.S. government.

INTEREST RATE RISK

Interest rate risk is the risk that bond prices will decline over short or even
long periods due to rising market interest rates. All bonds, including those
issued by the U.S. government and its agencies, are subject to interest rate
risk. Their prices tend to move in the opposite direction from market interest
rate movements. When interest rates go up, bond prices tend to fall; when rates
fall, prices tend to rise. Bonds with longer maturities are affected more by
interest rate movements than bonds with shorter maturities, bonds with interest
rate reset provisions, notes or money market instruments. If prices throughout
the economy were to decline over time, resulting in "deflation," the principal
and income of inflation-protected bonds held by an Underlying Fund would likely
decline in price, which would result in losses for the Underlying Fund.
Mortgage-backed securities represent interests in or instruments backed by a
pool of loans secured by mortgages and asset-backed securities represent
interests in or instruments backed by a pool of loans secured by other assets.
Mortgage-backed securities and asset-backed securities are also subject to
prepayment risk and extension risk. Prepayment risk is the risk that during
periods of falling interest rates, an issuer of mortgages and other securities
may be able to repay principal prior to the security's maturity, causing the
Underlying Fund to have to

- --------------------------------------------------------------------------------
     22                                        BARCLAYS GLOBAL INVESTORS FUNDS



reinvest in securities with a lower yield. Extension risk is the risk that when
interest rates rise, certain mortgage-backed securities will be paid off
substantially more slowly than originally anticipated and the value of those
securities may fall sharply. Both prepayment risk and extension risk may result
in a decline to the Underlying Funds' income.

HIGH YIELD SECURITIES RISK

High yield securities risk is the risk that securities that are rated below
investment-grade (commonly referred to as "junk bonds," include those bonds
rated lower than "BBB-" by S&P, a division of The McGraw-Hill Companies, Inc.
and Fitch Rating Service Inc. or "Baa3" by Moody's(Reg. TM) Investor's
Services, Inc.) or are unrated but judged by an Underlying Fund to be of
comparable quality, at the time of purchase, may be more volatile than
higher-rated securities of similar maturity.

High yield securities may also be subject to greater levels of credit or
default risk than higher-rated securities. The value of high yield securities
can be adversely affected by overall economic conditions, such as an economic
downturn or a period of rising interest rates, and high yield securities may be
less liquid and more difficult to sell at an advantageous time or price or to
value than higher-rated securities.

NON-U.S. SECURITIES RISKS

Investments in the securities of non-U.S. issuers are subject to all the risks
of investing in the market of such issuers, including market fluctuations
caused by factors such as economic and political developments, changes in
interest rates and abrupt changes in stock prices. As a result of Underlying
Funds' investing in non-U.S. securities, the Fund may be subject to the risks
listed below. These risks may decrease the value of your investment:

[] Lower levels of liquidity and market efficiency;

[] Greater securities price volatility;

[] Exchange rate fluctuations and exchange controls;

[] Less availability of public information about issuers;

[] Imposition of withholding or other taxes;

[] Imposition of restrictions on the expatriation of funds or other assets of
the Underlying Fund;

[] Higher transaction and custody costs and delays in settlement procedures;

[] Difficulties in enforcing contractual obligations;

[] Substantial government involvement in the economy;

[] Higher rates of inflation;

[] Greater social, economic and political uncertainty, the risk of
 nationalization or expropriation of assets and risk of war;

[] Lower levels of regulation of the securities markets;

[] Different accounting, disclosure and reporting requirements; and

[] Legal principles relating to corporate governance, director's fiduciary
 duties and liabilities and stockholder's rights in markets in which the
 Underlying Funds invest may differ and/or may not be as extensive or
 protective as those that apply in the United States.

Investments in non-U.S. securities may be made by an Underlying Fund directly
or through investments in American Depositary Receipts ("ADRs") and other
similar investments. ADRs are receipts for shares of non-U.S. stocks held on
deposit in U.S. banks or banks of major European countries. The receipts trade
on the U.S. or local European stock markets as would normal stocks, entitling
their owners to the dividends and capital gains earned by the real shares
stored in bank vaults. ADRs reduce some of the risks of foreign investing
because a large, liquid market generally exists

- --------------------------------------------------------------------------------
                                                                             23



and U.S. trading and settlement practices reduce currency, custodial and other
operational risks. Similar investments (European and Global Depositary
Receipts) are receipts for stock deposited in non-U.S. bank and trust
companies, trade across foreign and domestic markets, and can involve different
or greater risks than ADRs.

EMERGING MARKETS RISK

Some foreign markets are considered to be emerging markets. Investment in these
emerging markets is subject to a greater risk of loss than investments in a
developed market. This is due to, among other things, greater market
volatility, lower trading volume, political and economic instability, greater
risk of market shut down and more governmental limitations on foreign
investment policy than those typically found in a developed market.

MODEL RISK

Although the quantitative model used to manage the Master Portfolios' assets
has been developed and refined over many years, neither the Master Portfolios
nor BGFA can offer any assurance that the recommended allocation will either
maximize returns or minimize risks, nor can the Master Portfolios or BGFA offer
assurance that a recommended allocation will be the appropriate allocation in
all circumstances for every investor with a particular time horizon.

REAL ESTATE INVESTMENT RISK

Investment in equity securities in the real estate sector is subject to many of
the same risks associated with the direct ownership of real estate, such as
adverse changes in national, state or local real estate conditions (resulting
from, for example, oversupply of or reduced demand for space and changes in
market rental rates); obsolescence of properties; changes in the availability,
cost and terms of mortgage funds; and the impact of tax, environmental, and
other laws.

DERIVATIVES

Derivatives include, among other instruments, futures contracts, options on
futures contracts, other types of options that may be exchange-traded or traded
over-the-counter, indexed and inverse floating-rate securities, and swap
agreements. Derivatives are financial instruments whose values are derived, at
least in part, from the prices of other securities or specified assets, indexes
or rates. Some derivatives may be more sensitive than direct securities to
changes in interest rates or sudden market moves. Some derivatives also may be
susceptible to fluctuations in yield or value due to their structure or
contract terms.

PASSIVE INVESTMENT RISK

Because BGFA does not select individual companies in the underlying indexes for
the Underlying iShares Funds, those Underlying iShares Funds may hold stocks in
companies that present risks that an investment adviser researching individual
stocks might seek to avoid.

SECURITY SELECTION RISK

For each of Active Stock Master Portfolio and CoreAlpha Bond Master Portfolio,
BGFA bases security selection on its analysis of securities and therefore each
of these Master Portfolios is subject to the risk that poor security selection
will result in underperformance of the Master Portfolio in comparison with
other investment vehicles with similar investment objectives and strategies.

SECURITIES LENDING RISK

The LifePath Portfolios may also lend portfolio securities to borrowers that
provide collateral at least equal to the current market value of the securities
loaned, plus accrued interest or dividends. BGI acts as securities lending
agent for, and is compensated by, the LifePath Portfolios. Securities lending
collateral is generally reinvested in a joint account or money market funds,
including those advised by BGFA. Risks related to securities lending include
operational, credit, legal, counterparty and market risk, as well as investment
risks related to the collateral and risk of loss if the collateral is
liquidated.

     24                                        BARCLAYS GLOBAL INVESTORS FUNDS



CONCENTRATION RISK

To the extent that an underlying index of an Underlying iShares Fund is
concentrated in the securities of companies, a particular market industry,
group of industries, sector or asset class countries, regions or groups of
countries, that Underlying iShares Fund may be adversely affected by the
performance of those securities, may be subject to increased price volatility
and may be more susceptible to adverse economic, market, political or
regulatory occurrences affecting that market, industry, group of industries,
sector or asset class country, region or group of countries.

MARKET TRADING RISKS

The Underlying iShares Funds are subject to certain additional risks due to
their shares being listed and traded on securities exchanges. There can be no
assurance that an active trading market for these particular ETFs will develop
or be maintained. Trading in ETFs may be halted because of market conditions or
for reasons that, in the view of the listing exchange, make trading in ETFs
inadvisable. In addition, trading in ETFs is subject to trading halts caused by
extraordinary market volatility pursuant to "circuit breaker" rules. There can
be no assurance that the requirements necessary to maintain the listing of ETFs
will continue to be met or will remain unchanged. An ETF may trade at, above or
below its NAV. The NAV of an ETF will fluctuate with changes in the market
value of its holdings. The trading price of an ETF will generally fluctuate in
accordance with changes in its NAV, as well as market supply and demand.

TRACKING ERROR RISK

Imperfect correlation between an Underlying iShares Fund's securities and those
in its underlying index, rounding of prices, changes to the underlying index
and regulatory requirements, may cause "tracking error," which is measured as
the divergence of the Underlying iShares Fund's performance from that of its
underlying index. Tracking error also may result because an Underlying iShares
Fund incurs fees and expenses while its underlying index does not incur the
same expenses.

Management of the LifePath Portfolios

INVESTMENT ADVISER

Each LifePath Portfolio is a feeder fund that invests all of its assets in a
Master Portfolio that has a substantially identical investment objective,
strategies and policies as the LifePath Portfolio. The Master Portfolios, in
turn, invest in a combination of the Underlying Funds. BGFA, a registered
investment adviser, serves as investment adviser to each Master Portfolio, and
also serves as investment adviser to each Underlying Fund, with the exception
of the Underlying Money Market Fund, which invests in a Master Portfolio
advised by BGFA. BGFA manages the investing of the Master Portfolios' assets
and provides the Master Portfolios with investment guidance and policy
direction in connection with daily portfolio management, subject to the
supervision of the Master Portfolios' Board of Trustees. For its services to
the Master Portfolios, BGFA is entitled to receive an annual advisory fee of
0.35% of each Master Portfolio's average daily net assets.

For its services to the Underlying Funds, BGFA receives fees that differ from
the fees described for the LifePath Portfolios in this Prospectus. BGFA
provides investment advisory services for the Underlying Funds that differ from
the investment advisory services it provides for the Master Portfolios. For
those services, BGFA receives investment advisory fees from the Underlying
Funds. In addition, BGI provides administration services to certain of the
Underlying Funds and, for those services, may receive administration fees from
those Underlying Funds. BGFA has contractually agreed to waive its management
fees at the Master Portfolio level in an amount equal to advisory and
administration fees, if any, paid by the Underlying Funds to BGFA and BGI,
respectively, through April 30, 2011.

BGFA is located at 400 Howard Street, San Francisco, CA 94105. It is a
wholly-owned subsidiary of BGI, which in turn is a majority-owned subsidiary of
Barclays Bank PLC. As of February 28, 2009, BGI and its affiliates, including
BGFA, provided investment advisory services for assets in excess of $1.36
trillion. BGI, BGFA, Barclays Global Investors Services, Barclays Bank PLC and
their affiliates deal, trade and invest for their own accounts in the types of
securities in which the Master Portfolios invest.

A discussion regarding the basis for the Master Portfolios' Board of Trustees'
approval of the investment advisory agreements with BGFA is available in each
LifePath Portfolio's semi-annual report for the six-month period ending June
30.

PORTFOLIO MANAGERS

Dagmar Nikles, Leslie Gambon and Dale Hogan (the "Portfolio Managers") are
primarily responsible for the day-to-day management of the Master Portfolios
and act collaboratively on all aspects concerning the Master Portfolios. Each
Portfolio Manager is responsible for various functions related to portfolio
management, including, but not limited to, investing cash inflows, coordinating
with members of their team to focus on certain asset classes, implementing
investment strategy, researching and reviewing investment strategy, and
overseeing members of his or her portfolio management team with more limited
responsibilities.

Ms. Nikles is an employee of BGFA and BGI and has been one of the Portfolio
Managers primarily responsible for the day-to-day management of the Master
Portfolios since June 2005. Ms. Nikles has been a member of the asset
allocation portfolio management team since July 2003. From September 2002 to
June 2003, Ms. Nikles was pursuing her Financial Risk Manager certification.

Ms. Gambon is an employee of BGFA and BGI and has been one of the Portfolio
Managers primarily responsible for the day-to-day management of the Master
Portfolios since May 2007. Ms. Gambon has been a member of the asset allocation
portfolio management team since April 2007. Prior to becoming a member of the
asset allocation portfolio

- --------------------------------------------------------------------------------
     26                                        BARCLAYS GLOBAL INVESTORS FUNDS



management team, Ms. Gambon was an Active Equity Product Manager with BGI from
2001 to 2004 and in October 2004 became Head of Defined Contribution Portfolio
Management at BGI.

Mr. Hogan is an employee of BGFA and BGI and has been one of the Portfolio
Managers primarily responsible for the day-to-day management of the Master
Portfolios since October 2008. Mr. Hogan has been a member of the asset
allocation portfolio management team since May 2007. Prior to becoming a
Portfolio Manager, Mr. Hogan was a derivatives trader with Credit Suisse from
2004 to 2006. From April 2002 through April 2004, Mr. Hogan was a currency
trader at BGI.

The LifePath Portfolios' SAI provides additional information about the
Portfolio Managers' compensation, other accounts managed by the Portfolio
Managers, and the Portfolio Managers' ownership of shares in the LifePath
Portfolios that invest in the Master Portfolios for which they are Portfolio
Managers.

ADMINISTRATIVE SERVICES

BGI provides the following services, among others, as the LifePath Portfolios'
administrator:

[] Supervise the LifePath Portfolios' administrative operations;

[] Provide or cause to be provided management reporting and treasury
administration services;

[] Financial reporting;

[] Legal, blue sky and tax services;

[] Preparation of proxy statements and shareholder reports; and

[] Engaging and supervising shareholder servicing agents (the "Shareholder
 Servicing Agents") on behalf of the LifePath Portfolios.

BGI is entitled to receive fees for these services at the annual rate of 0.50%
of the average daily net assets of the Class R Shares of each LifePath
Portfolio. In addition to performing these services, BGI has agreed to bear all
costs of operating the LifePath Portfolios, other than brokerage expenses,
advisory fees, distribution fees, certain fees and expenses related to the
LifePath Portfolios' Independent Trustees and their counsel, auditing fees,
litigation expenses, taxes or other extraordinary expenses.

The Shareholder Servicing Agents service individual and omnibus LifePath
Portfolio accounts pursuant to agreements with the LifePath Portfolios and/or
BGI. In addition to serving as agents of the LifePath Portfolios for purposes
of accepting orders for purchases and redemptions of LifePath Portfolio shares,
Shareholder Servicing Agents may provide administrative support and account
services such as processing purchases and redemptions of shares on behalf of
individual and omnibus LifePath Portfolio accounts, answering shareholder
inquiries, keeping records, transmitting reports and communications from the
LifePath Portfolios, and providing reports on the status of individual and
omnibus accounts. Shareholder Servicing Agents may provide these services, in
whole or in part, by operating electronic transaction systems or websites
through which shareholders may obtain information or engage in purchase or
redemption transactions of LifePath Portfolio shares. By operating these
systems or providing other services described above, the Shareholder Servicing
Agents make the LifePath Portfolios available to their clients.

BGI pays shareholder servicing fees to certain Shareholder Servicing Agents in
amounts not exceeding the maximum fee rates approved by the LifePath
Portfolios' Board of Trustees for those services that the Shareholder Servicing
Agents perform for their clients that would otherwise be performed by BGI or
the LifePath Portfolios' other service providers. In addition, BGFA and/or BGI
pay additional amounts to certain Shareholder Servicing Agents for more
services or to other intermediaries that perform services in connection with a
LifePath Portfolio's shares. These amounts, which may be significant, are paid
by BGFA and/or BGI from their own resources, which generally come directly or
indirectly from fees paid by funds advised by BGFA or administered by BGI. The
LifePath Portfolios' distributor may also pay certain Shareholder Servicing
Agents or intermediaries for such services from its own resources, which
generally come directly or indirectly from fees paid by BGI.

- --------------------------------------------------------------------------------
                                                                             27



A Shareholder Servicing Agent may make decisions about which investment options
it will service and make available to its clients based on the payments the
Shareholder Servicing Agent may be eligible to receive for its services.
Therefore, payments to a Shareholder Servicing Agent may create potential
conflicts of interest between the Shareholder Servicing Agent and its clients
where the Shareholder Servicing Agent determines which investment options it
will make available to those clients. Additional information regarding the
LifePath Portfolios' shareholder servicing arrangements can be found in the
LifePath Portfolios' SAI, which is available upon request.

DISTRIBUTION PLAN

The LifePath Portfolios have adopted a Distribution Plan applicable to Class R
Shares pursuant to Rule 12b-1 under the Investment Company Act of 1940, as
amended. Class R is the only class that has a Distribution Plan. This plan is
used to pay for distribution-related services, including ongoing compensation
to selling agents. The Rule 12b-1 fees are paid out of Class R's assets. Over
time, these fees will increase the cost of your investment in Class R Shares
and may cost you more than paying other types of sales arrangements. The Rule
12b-1 fees are paid at an annual rate of 0.25% of the average daily net assets
of the Class R Shares of the relevant LifePath Portfolios.

Shareholder Information

WHO IS ELIGIBLE TO INVEST

To be eligible to purchase LifePath Portfolio Class R Shares, you must:

[] Invest through an employer-sponsored or individual retirement savings plan;

[] Invest the proceeds rolled over from such retirement savings plan into an
IRA; or

[] Maintain an account with State Street Bank and Trust Company ("State
 Street"), the LifePath Portfolios' custodian, transfer agent and dividend
 disbursing agent, or with one of the LifePath Portfolios' Shareholder
 Servicing Agents.

The LifePath Portfolios offer other classes of shares (Class I Shares and Class
S Shares) with different features and expense levels, which you may be eligible
to buy. Please see the LifePath Portfolios' Class I Shares and Class S Shares
prospectuses for more information.

In order to invest, a completed account application form must be submitted to,
and processed by, your Shareholder Servicing Agent or State Street and an
account number assigned. You may be asked to provide information to verify your
identity when opening an account.

Your Shareholder Servicing Agent may charge you a fee and may offer additional
account services. Additionally, your Shareholder Servicing Agent may have
procedures for placing orders for Class R Shares that differ from those of the
LifePath Portfolios, such as different investment minimums or earlier trading
deadlines. Please contact your Shareholder Servicing Agent directly for more
information and details.

HOW TO BUY SHARES

[] PLAN PARTICIPANT. Invest through payroll deductions or make a direct
 contribution by rolling over an amount from another 401(k) plan or from a
 rollover IRA (make arrangements through your employer). If you are investing
 through a Shareholder Servicing Agent, your Shareholder Servicing Agent is
 responsible for properly transmitting your purchase order to State Street and
 may impose an earlier deadline than the LifePath Portfolios, as described
 below.

- --------------------------------------------------------------------------------
     28                                        BARCLAYS GLOBAL INVESTORS FUNDS



[] TAX-DEFERRED INVESTOR. Invest through a Shareholder Servicing Agent as
provided in your benefit plan documents. Your Shareholder Servicing Agent, plan
sponsor or administrator is responsible for properly transmitting your purchase
order to State Street and may impose an earlier deadline for purchase and
redemption orders than the LifePath Portfolios, as described below.

[] QUALIFIED BUYER. Invest through an account set up with State Street or your
 Shareholder Servicing Agent. Your Shareholder Servicing Agent is responsible
 for properly transmitting your purchase order to State Street and may impose
 an earlier deadline than the LifePath Portfolios, as described below.

You may buy LifePath Portfolio shares without paying a sales charge. Your
purchase order must be received in proper form, as determined by State Street
or an intermediary pursuant to an appropriate agreement, by the close of
regular trading on the New York Stock Exchange ("NYSE") (generally 4:00 p.m.
Eastern Time) (or if regular trading on the NYSE closes early, at such closing
time) on any day the LifePath Portfolios are open (a "Business Day") to
purchase shares at that day's NAV. Orders received after the close of regular
trading on the NYSE will be executed on the next Business Day. The LifePath
Portfolios are generally open Monday through Friday and are generally closed on
weekends and any day on which the NYSE is closed.

Each LifePath Portfolio reserves the right to suspend or discontinue the offer
and sale of its shares and reject or cancel any purchase order for any reason.

Purchases generally must be made in U.S. dollars. You may be charged for any
costs incurred in connection with a purchase order that has been placed but for
which the LifePath Portfolio has not received full payment.

HOW TO SELL SHARES

[] PLAN PARTICIPANT AND TAX-DEFERRED INVESTOR. Contact your plan sponsor,
 administrator or Shareholder Servicing Agent. Your Shareholder Servicing Agent
 is responsible for properly transmitting your sale order to State Street.

[] QUALIFIED BUYER. Contact your Shareholder Servicing Agent. Your Shareholder
 Servicing Agent is responsible for properly transmitting your sale order to
 State Street.

You may sell LifePath Portfolio shares without paying a sales charge. Your
order to sell shares must be received in proper form, as determined by State
Street or an intermediary pursuant to an appropriate agreement, by the close of
regular trading on the NYSE (generally 4:00 p.m. Eastern Time) (or if regular
trading on the NYSE closes early, at such closing time) on any Business Day to
sell shares at that day's NAV. Orders received after the close of regular
trading on the NYSE will be executed on the next Business Day.

The LifePath Portfolios generally remit the proceeds from a sale the next
Business Day after receiving a properly executed order to sell and no longer
than seven days after the sale. Each LifePath Portfolio reserves the right to
suspend your right of redemption and to delay delivery of your redemption
proceeds up to seven days, as permitted under applicable law. Each LifePath
Portfolio further reserves the right to automatically redeem your shares and
close your account for any reason, subject to applicable law, and send you the
proceeds, which would reflect the NAV on the day the LifePath Portfolio
automatically redeems your shares. For example, a LifePath Portfolio may
automatically redeem your shares to reimburse the LifePath Portfolio for any
losses sustained by reason of your failure to make full payment for shares
purchased or to collect any charge relating to a transaction effected for your
benefit that is applicable to the LifePath Portfolio's shares as provided from
time to time in this Prospectus.

In addition, each LifePath Portfolio reserves the right to send your redemption
proceeds in the form of securities from its Master Portfolio.

Upon redemption, the identity of the holder of the account to which the

CALCULATING THE LIFEPATH PORTFOLIOS' SHARE PRICE

Each LifePath Portfolio's share price (also known as a LifePath Portfolio's
NAV) is calculated by dividing the value of the net assets of the LifePath
Portfolio (I.E., the value of its total assets less total liabilities) by the
total number of outstanding shares of the LifePath Portfolio, generally rounded
to the nearest cent.

Each LifePath Portfolio's NAV is calculated at the close of regular trading on
the NYSE (generally, 4:00 p.m. Eastern Time) on any Business Day. If regular
trading on the NYSE closes early, the time for calculating each LifePath
Portfolio's NAV and the deadline for share transactions will be accelerated to
the earlier closing time. The NAV of each LifePath Portfolio is calculated
based on the net asset value of the Master Portfolio in which the LifePath
Portfolio invests. The LifePath Portfolios' SAI includes a description of the
methods for valuing the Master Portfolios' investments, including a description
of the circumstances in which the Master Portfolios' investments would be
valued using fair value pricing and the effects of using fair value pricing.

LIFEPATH PORTFOLIO DISTRIBUTIONS

The LifePath Portfolios distribute their net investment income to shareholders
quarterly. The LifePath Portfolios distribute their net realized capital gains,
if any, to shareholders at least annually. Distributions payable to you will be
automatically reinvested in additional Class R Shares of your LifePath
Portfolio, unless you have elected to receive distribution payments in cash.

FREQUENT TRADING IN LIFEPATH PORTFOLIO SHARES

Frequent purchases and redemptions of mutual fund shares ("frequent trading")
may have a detrimental effect on a fund and its shareholders. Depending on
various factors, such as the size of the fund's investment portfolio and the
amount of assets maintained in cash, frequent trading may harm the performance
of the fund by interfering with the implementation of its investment strategies
and/or increasing transaction costs and taxes, and/or may dilute the value of
fund shares held by long-term investors. Frequent trading may include activity
that appears to attempt to take advantage of a potential arbitrage opportunity
presented by a lag between a change in the value of a fund's investment
portfolio securities after the close of the primary markets for those portfolio
securities and the reflection of that change in the fund's net asset value
("market timing").

Each LifePath Portfolio invests only in interests of its Master Portfolio, and
the Boards of Trustees of the Master Portfolios and the LifePath Portfolios
have each considered the issues of frequent trading and market timing.

The Master Portfolios' Board of Trustees has adopted a policy of not monitoring
for possible market timing activity because the Master Portfolios' holdings are
valued as of the same time that the net asset value of the Master Portfolios is
calculated (generally 4:00 p.m. Eastern Time), which eliminates the potential
arbitrage opportunity presented by a lag between a change in the value of the
Master Portfolios' holdings and the reflection of that change in the Master
Portfolios' respective net asset values. The Master Portfolios' Board of
Trustees has not adopted a policy of monitoring for other forms of frequent
trading because daily flows into and out of the Master Portfolios are
aggregated, and the process of aggregation is expected to reduce the potential
for frequent trading to disrupt the implementation of the Master Portfolios'
investment strategies.

The LifePath Portfolios' Board of Trustees has not adopted a policy of
monitoring for market timing or other frequent trading activity in the LifePath
Portfolios in light of the nature of the LifePath Portfolios' investment in
Master Portfolios, the policies of the Master Portfolios, as described in the
preceding paragraphs, and the historical nature of flows into and out of the
LifePath Portfolios.

BGI's ability to monitor trades that are placed by participants in plans that
are shareholders in the LifePath Portfolios or other shareholders in the
LifePath Portfolios that trade through omnibus accounts maintained by
intermediaries will be severely limited to the extent BGI does not receive
transaction information showing individual investment decisions. Upon request
by the LifePath Portfolios, intermediaries are required to provide certain
transaction information that may enable the LifePath Portfolios to identify
trading activity that is potentially harmful to the LifePath Portfolios. The

- --------------------------------------------------------------------------------
     30                                        BARCLAYS GLOBAL INVESTORS FUNDS



LifePath Portfolios may, but do not have the obligation to, respond to any
potentially harmful trading activity that is identified. In the event any
potentially harmful trading activity is identified, responses may include the
imposition of trading restrictions, the rejection of purchases, or such other
steps the LifePath Portfolios determine are appropriate. Intermediaries'
ability to impose restrictions on the trading practices of their clients may,
however, be affected by legal or technological limitations.

TAXES

The following discussion regarding U.S. federal income taxes is based upon laws
in effect as of the date of this Prospectus and summarizes only some of the
important U.S. federal income tax considerations affecting the LifePath
Portfolios and their U.S. shareholders. This discussion is not intended as a
substitute for careful tax planning. Please see the SAI for additional U.S.
federal income tax information.

Distributions from your LifePath Portfolio's net investment income and net
realized capital gains are taxable, whether you choose to receive them in cash
or automatically reinvest them in additional LifePath Portfolio shares. The
amount of taxes you owe will vary depending on your tax status and on your tax
rate and the amount and character of the LifePath Portfolio's distributions to
you. Normally, distributions are taxable to you when paid. However, when
distributions are declared in the last three months of a year and paid in
January of the next year, they are taxable as if paid on December 31 of the
prior year.

Distributions from the LifePath Portfolios generally are taxable as follows:



DISTRIBUTION TYPE           TAX STATUS
- -------------------------   --------------------------------
                         
Qualified dividend
  income ................   Qualified dividend income(1)(2)
Other income.............   Ordinary income(2)
Short-term capital gain .   Ordinary income
Long-term capital gain...   Long-term capital gain(3)


- -------
  (1)   If you are an individual, your distributions attributable to the
        LifePath Portfolio's qualified dividend income generally are taxable to
        you at a maximum 15% U.S. federal income tax rate, as long as you meet
        certain holding period and other requirements. Qualified dividend
        income is, in general, dividend income received from taxable U.S. and
        certain foreign corporations. Absent further legislation, the reduced
        rates of tax for qualified dividend income will expire after December
        31, 2010.
  (2)   A portion of distributions paid to corporate shareholders of the
        LifePath Portfolios may qualify for the dividends-received deduction
        available to corporations.
  (3)   An individual's net long-term capital gain currently is subject to a
        reduced maximum 15% U.S. federal income tax rate. Absent further
        legislation, this reduced 15% maximum tax rate on long-term capital
        gain is scheduled to expire after December 31, 2010.

In addition, if you sell your LifePath Portfolio shares you generally will have
a taxable capital gain or loss in an amount equal to the difference between the
net amount of sale proceeds that you receive and your tax basis for the shares
that you sell. In certain circumstances, a loss on the sale may be disallowed:



TRANSACTION                   TAX STATUS
- ---------------------------   --------------------------------
                           
You sell shares owned
  for more than one year ..   Long-term capital gain or loss
You sell shares owned
  for one year or less ....   Short-term capital gain or loss


If you buy a LifePath Portfolio's shares shortly before it makes a
distribution, you will, in effect, receive part of your purchase back in the
form of a taxable distribution. Similarly, if you buy shares of a LifePath
Portfolio that holds appreciated securities, you will, in effect, receive part
of your purchase back in a taxable distribution if and when the LifePath
Portfolio sells the appreciated securities and distributes the realized gain on
the sale. The LifePath Portfolios have built up, or have the potential to build
up, high levels of unrealized appreciation in their investments.

- --------------------------------------------------------------------------------
                                                                             31



After the end of each year, the LifePath Portfolios will send to you a notice
that tells you how much you have received in distributions during the year and
their U.S. federal income tax status. You could also be subject to foreign,
state and local taxes on such distributions.

In certain circumstances, you may be subject to back-up withholding taxes on
distributions to you from the LifePath Portfolios if you fail to provide the
LifePath Portfolios with your correct social security number or other taxpayer
identification number, or to make required certifications, or if you have been
notified by the Internal Revenue Service that you are subject to back-up
withholding.

TAX CONSIDERATIONS FOR TAX-EXEMPT OR FOREIGN INVESTORS OR THOSE HOLDING
LIFEPATH PORTFOLIO SHARES THROUGH A TAX-DEFERRED ACCOUNT, SUCH AS A 401(K) PLAN
OR IRA, WILL BE DIFFERENT. FOR EXAMPLE, SHAREHOLDERS THAT ARE EXEMPT FROM U.S.
FEDERAL INCOME TAX, SUCH AS RETIREMENT PLANS THAT ARE QUALIFIED UNDER SECTION
401 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED, GENERALLY ARE NOT SUBJECT
TO U.S. FEDERAL INCOME TAX ON LIFEPATH PORTFOLIO DIVIDENDS OR DISTRIBUTIONS OR
ON SALES OF LIFEPATH PORTFOLIO SHARES. BECAUSE EACH INVESTOR'S TAX
CIRCUMSTANCES ARE UNIQUE AND BECAUSE TAX LAWS ARE SUBJECT TO CHANGE, YOU SHOULD
CONSULT YOUR TAX ADVISOR ABOUT YOUR INVESTMENT.

MASTER/FEEDER MUTUAL FUND STRUCTURE

The LifePath Portfolios do not have their own investment adviser. Instead, each
LifePath Portfolio invests all of its assets in a separate mutual fund, called
a Master Portfolio, that has a substantially identical investment objective,
strategies and policies as the LifePath Portfolio. BGFA serves as investment
adviser to each Master Portfolio. The Master Portfolios may accept investments
from other feeder funds. Certain actions involving other feeder funds, such as
a substantial withdrawal, could affect the Master Portfolios and, therefore,
the LifePath Portfolios.

FEEDER FUND EXPENSES

Feeder funds, including the LifePath Portfolios, bear their respective Master
Portfolio's expenses in proportion to the amount of assets each invests in the
Master Portfolio. Each feeder fund can set its own transaction minimums,
fund-specific expenses and conditions.

FEEDER FUND RIGHTS

Under the master/feeder structure, the LifePath Portfolios' Board of Trustees
retains the right to withdraw a LifePath Portfolio's assets from its Master
Portfolio if it believes doing so is in the best interests of the LifePath
Portfolio's shareholders. If the Board of Trustees decides to withdraw a
LifePath Portfolio's assets, it would then consider whether the LifePath
Portfolio should hire its own investment adviser, invest in another master
portfolio or take other action.

FUND OF FUNDS

The Master Portfolios do not invest directly in a portfolio of securities.
Instead, they invest in the Underlying Money Market Fund and other Underlying
Funds that are also advised by BGFA. Each Master Portfolio charges for its own
direct expenses, in addition to bearing a PRO RATA share of the expenses
charged by the Underlying Funds in which it invests.

Overview

INTRODUCTION

The LifePath Portfolios/1/ are designed to offer individual investors
comprehensive asset allocation strategies tailored to the time when they expect
to begin withdrawing assets. Asset allocation is the distribution of
investments among broad types of asset classes: equity securities, bonds and
money market instruments. Each LifePath Portfolio invests all of its assets in
a separate mutual fund, called a Master Portfolio, that has a substantially
identical investment objective as the LifePath Portfolio. To implement the
asset allocation strategy, each Master Portfolio, in turn, invests in a
combination of equity securities, bond and money market funds (the "Underlying
Funds") in proportions based on its own comprehensive investment strategy that
gradually becomes more conservative as the year in the LifePath Portfolio's
name approaches, except for the LifePath Retirement Portfolio, which is already
in its most conservative phase. Barclays Global Fund Advisors ("BGFA") is the
investment adviser to the Master Portfolios.

WHICH LIFEPATH PORTFOLIO TO CONSIDER

The first step in choosing which LifePath Portfolio to consider is answering a
key question: When will you need the money you are thinking of investing? Will
it be in ten years, when your kids are ready for college? Or 30 years, when you
retire?

The number in the name of most of the LifePath Portfolios is actually a year -
a "target year" when you might expect to begin withdrawing your money.
Selecting the LifePath Portfolio that may be most appropriate for your
investment may be as simple as matching your target year with the closest
LifePath Portfolio target year.

For example, let's say that you are investing for retirement purposes, and that
you expect to retire at age 60. If you are 45 years old, you have 15 years
before retirement. By adding 15 to the current year, you can define your
"target year." If you expect to retire in the year 2023, as in this example,
you may conclude that the LifePath 2020 Portfolio is the most appropriate
LifePath Portfolio for you.

- -------
(1)For simplicity's sake, all discussion of investment objective, strategies
   and risks of a particular LifePath Portfolio refers also to the investment
   objective, strategies and risks of the Master Portfolio, unless otherwise
   indicated. A detailed description of the relationship of the LifePath
   Portfolios to their Master Portfolios appears under the heading
   "Shareholder Information - Master/Feeder Mutual Fund Structure" in this
   Prospectus.

LIFEPATH(Reg. TM) PORTFOLIOS - HOW THEY WORK

[GRAPHIC APPEARS HERE]

NOTE: THE ABOVE CHART IS FOR ILLUSTRATIVE PURPOSES ONLY AND DOES NOT REPRESENT
THE ACTUAL ALLOCATION PERCENTAGES OF THE LIFEPATH PORTFOLIOS.

The chart shows that over time, the investment mix of each LifePath Portfolio
gradually shifts from a greater concentration of higher-risk investments
(namely, equity securities funds) to a greater concentration of lower-risk
investments (namely, bond funds), thereby making the LifePath Portfolio
increasingly conservative.

In making your investment decision, you should keep in mind:

[] Each LifePath Portfolio's investment strategy derives from the risk
 tolerance of average investors with a particular time horizon.

[] Each LifePath Portfolio's time horizon is based on the year in its name,
 except for the LifePath Retirement Portfolio, which is designed for investors
 who are currently withdrawing, or plan in the near future to begin
 withdrawing, a substantial portion of their investment.

If you are willing to accept a greater risk of short-term loss in exchange for
the potential to achieve higher long-term returns, you may invest some or all
of your assets in a LifePath Portfolio with a longer time horizon. If you
desire a more conservative investment and are willing to forego some potential
returns, you may invest some or all of your assets in a LifePath Portfolio with
a shorter time horizon. The final choice is yours.

Investment Objectives

Each LifePath Portfolio seeks to maximize return consistent with the
quantitatively measured risk that investors on average may be willing to accept
given their investment time horizon. An investor's time horizon marks the point
when the investor plans to start making net withdrawals from his or her
investments. As a general rule, investors with a longer time horizon have a
greater tolerance for risk than investors with a shorter time horizon.
Long-term investors are more likely to accept a greater risk of short-term loss
in exchange for the potential to achieve higher long-term returns. Each
LifePath Portfolio has its own time horizon, which affects the targeted risk
level of the LifePath Portfolio and, in turn, its asset allocation.

SPECIFICALLY:

[] LifePath Retirement Portfolio is managed for investors seeking income and
moderate long-term growth of capital.

[] LifePath 2010 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2010.

[] LifePath 2020 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2020.

[] LifePath 2030 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2030.

[] LifePath 2040 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2040.

[] LifePath 2050 Portfolio is managed for investors planning to retire (or
 begin to withdraw substantial portions of their investment) approximately in
 the year 2050.

Each LifePath Portfolio's investment objective may be changed by the LifePath
Portfolio's Board of Trustees without shareholder approval.

- --------------------------------------------------------------------------------
                                                                              3



Summary of Principal Investment Strategies
Each LifePath Portfolio invests all of its assets in a corresponding Master
Portfolio which allocates and reallocates its assets among the Underlying
Funds. The Master Portfolios with longer time horizons invest a greater portion
of their assets in Underlying Funds that invest in equity securities, which
provide a greater opportunity for capital appreciation over the long-term but
have a greater risk of short-term loss. The Master Portfolios with shorter time
horizons invest a greater portion of their assets in Underlying Funds that
invest in bonds and money market instruments, which typically offer reduced
risk and price volatility but forego some potential returns. Accordingly, under
normal circumstances, the LifePath Portfolios with shorter time horizons have
lower expected returns than the LifePath Portfolios with longer time horizons.

[] LifePath Retirement Portfolio is designed for investors seeking current
 income and moderate long-term growth of capital. As of March 31, 2009, the
 LifePath Retirement Portfolio held approximately 38% of its assets in
 Underlying Funds that invest primarily in equity securities, 62% of its assets
 in Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 Because the LifePath Retirement Portfolio is in its most conservative phase,
 its allocation generally does not become more conservative over time, although
 its allocation may change to maintain the LifePath Retirement Portfolio's risk
 profile.

[] LifePath 2010 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2010. As of March 31, 2009, the
 LifePath 2010 Portfolio held approximately 40% of its assets in Underlying
 Funds that invest primarily in equity securities, 60% of its assets in
 Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 As the stated time horizon approaches, the allocation will become more
 conservative and have lower expected returns.

[] LifePath 2020 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2020. As of March 31, 2009, LifePath
 2020 Portfolio held approximately 61% of its assets in Underlying Funds that
 invest primarily in equity securities, 39% of its assets in Underlying Funds
 that invest primarily in bonds and the remainder of its assets in Underlying
 Funds that invest primarily in money market instruments. As the stated time
 horizon approaches, the allocation will become more conservative and have
 lower expected returns.

[] LifePath 2030 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2030. As of March 31, 2009, the
 LifePath 2030 Portfolio held approximately 76% of its assets in Underlying
 Funds that invest primarily in equity securities, 24% of its assets in
 Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 As the stated time horizon approaches, the allocation will become more
 conservative and have lower expected returns.

[] LifePath 2040 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2040. As of March 31, 2009, the
 LifePath 2040 Portfolio held approximately 89% of its assets in Underlying
 Funds that invest primarily in equity securities, 11% of its assets in
 Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 As the stated time horizon approaches, the allocation will become more
 conservative and have lower expected returns.

[] LifePath 2050 Portfolio is designed for investors expecting to retire or to
 begin withdrawing assets around the year 2050. As of March 31, 2009, the
 LifePath 2050 Portfolio held approximately 99% of its assets in Underlying
 Funds that invest primarily in equity securities, 1% of its assets in
 Underlying Funds that invest primarily in bonds and the remainder of its
 assets in Underlying Funds that invest primarily in money market instruments.
 As the stated time horizon approaches, that allocation will become more
 conservative and have lower expected returns.

When a LifePath Portfolio reaches its stated time horizon and enters its most
conservative phase - E.G., the LifePath 2010 Portfolio - the allocation of its
assets is expected to be similar to that of the LifePath Retirement Portfolio.
Such LifePath Portfolio and the LifePath Retirement Portfolio may then continue
to operate as separate funds or, subject to approval by the LifePath
Portfolios' Board of Trustees, they may be merged into a single fund.

Summary of Principal Risk Factors

As with any investment, your investment in the LifePath Portfolios could lose
money or the Portfolios' performance could trail that of other investments.

EACH LIFEPATH PORTFOLIO HAS A DIFFERENT LEVEL OF RISK.

The value of your investment is subject to equity securities market risk, which
means the price of the equity securities in which the Underlying Funds invest
may fluctuate or fall in response to economic events or trends.

The value of your investment is also subject to bond investment risks,
including interest rate risk, which means that the prices of bonds in which the
Underlying Funds invest may fall because of a rise in interest rates; credit
risk, which is the risk that the price of an individual bond may fall with the
decline in an issuer's real or apparent ability to meet its financial
obligations; extension risk, which is the risk that borrowers may extend the
prepayment of their mortgages or loans for longer periods than expected,
thereby affecting the security's average life and, potentially, its yield; and
prepayment risk, which is the risk that borrowers may prepay their mortgages or
loans faster than expected, thereby affecting the security's average life and,
potentially, its yield. The risk of default and price volatility of high yield
securities is greater than the risk usually associated with higher-rated
securities.

Investments in foreign securities by the Underlying Funds are subject to
certain special risks and considerations, including potentially less liquidity
and greater price volatility than investments in securities traded in the U.S.
markets. These risks are greater for investments in foreign securities issued
by companies or sovereign entities in emerging market countries.

The allocation of each LifePath Portfolio's assets is managed using a
quantitative model that has been developed based on a number of factors.
Neither the LifePath Portfolios nor BGFA can offer any assurance that the
recommended asset allocation will either maximize returns or minimize risk or
be the appropriate allocation in all circumstances for every investor with a
particular time horizon.

The value of your investment is also subject to passive investment risk,
security selection risk and concentration risk. Because BGFA does not select
individual companies in the underlying indexes for certain Underlying Funds,
those Underlying Funds may hold stocks in companies that present risks that an
adviser researching individual stocks might seek to avoid. This is known as
passive investment risk. In the case of the Underlying Funds where BGFA does
select securities based on its analysis, these funds are subject to the risk
that security selection will contribute to underperformance. Concentration risk
is the risk that an Underlying Fund that concentrates in a single industry or
group of industries may be more susceptible to any single economic, market,
political or regulatory occurrence in that industry or group of industries.

The value of your investment is subject to real estate investment risk, which
includes many of the same risks associated with the direct ownership of real
estate.

Investments in derivatives by certain Underlying Funds are subject to special
risks and considerations. Derivatives are financial instruments whose values
are derived, at least in part, from the prices of other securities or specified
assets, indexes or rates.

Certain Underlying Funds are also subject to market trading risks due to their
shares being listed and traded on securities exchanges (including potential
halts in trading or a fluctuation in trading price in accordance with changes
in net asset value), and tracking error risk, in that the return of an
Underlying Fund that seeks to track an index may deviate from the return of
such index.

- --------------------------------------------------------------------------------
                                                                              5



The LifePath Portfolios must maintain cash balances to meet redemption
requests, which may lower overall portfolio performance.

An investment in a LifePath Portfolio is not a bank deposit and it is not
insured or guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

Investment Returns

TOTAL RETURNS

The bar charts and table in this section provide some indication of the risks
of investing in the LifePath Portfolios by showing the changes in their
performance from year to year. The bar charts show the returns for Class S of
each LifePath Portfolio for each of the last ten calendar years./1/ The average
annual total return table compares the average annual total returns (before and
after taxes) of Class S of each LifePath Portfolio to those of a corresponding
index for various periods of time. Effective March 15, 2004, the returns for
each LifePath Portfolio reflect its Master Portfolio's investment in Underlying
Funds. For all periods prior to March 15, 2004, the returns for each LifePath
Portfolio reflect the direct investment by its Master Portfolio in a portfolio
of securities and also reflect investment in accordance with a model that
included "tactical," or short-term, shifts in allocation between stocks and
bonds. In addition, as of December 31, 2003, BGFA made certain changes to its
asset allocation strategies for the LifePath Portfolios, including a change to
the frequency with which the LifePath Portfolios' respective holdings were
rebalanced among asset classes from monthly to quarterly.

How the LifePath Portfolios performed in the past (before and after taxes) is
not necessarily an indication of how they will perform in the future.

  (1)   Performance shown for the periods prior to May 30, 2008 (the date the
        Class S Shares commenced operations) reflects the performance of the
        Class I Shares adjusted to reflect the fees and expenses of the Class S
        Shares. Performance from May 30, 2008 reflects the actual performance
        of Class S Shares. Effective March 15, 2004, the returns for each
        LifePath Portfolio reflect its Master Portfolio's investment in
        Underlying Funds. For all periods prior to March 15, 2004, the returns
        for each LifePath Portfolio reflect the direct investment by its Master
        Portfolio in a portfolio of securities and also reflect investment in
        accordance with a model that included "tactical," or short-term, shifts
        in allocation between stocks and bonds. In addition, as of December 31,
        2003, BGFA made certain changes to its asset allocation strategies for
        the LifePath Portfolios, including a change to the frequency with which
        the LifePath Portfolios' respective holdings were rebalanced among
        asset classes from monthly to quarterly.

  (3)   After tax returns in the table above are calculated using the
        historical highest individual federal marginal income tax rates and do
        not reflect the impact of state, local or foreign taxes. Actual
        after-tax returns depend on an investor's tax situation and may differ
        from those shown, and after-tax returns shown are not relevant to
        tax-exempt investors or investors who hold shares through tax-deferred
        arrangements, such as 401(k) plans or individual retirement accounts
        ("IRAs"). A LifePath Portfolio's returns after taxes on distributions
        and sale of LifePath Portfolio shares are calculated assuming that an
        investor has sufficient capital gains of the same character from other
        investments to offset any capital losses from the sale of LifePath
        Portfolio shares. As a result, a LifePath Portfolio's returns after
        taxes on distributions and sale of LifePath Portfolio shares may exceed
        the LifePath Portfolio's returns before taxes and/or returns after
        taxes on distributions.
  (4)   The LifePath Portfolios' custom benchmarks are hypothetical
        representations of the performance of the respective LifePath
        Portfolio's asset classes according to their weightings as of the most

        included in the LifePath Portfolios' custom benchmarks are adjusted
        quarterly to reflect the LifePath Portfolios' changing asset
        allocations over time. As of December 31, 2008, the following indexes
        are used to calculate the LifePath Portfolios' custom benchmarks: S&P
        500 Index, S&P 400 Index, S&P 600 Index, Barclays Capital U.S.
        Aggregate Bond Index, Citigroup 3-Month Treasury Bill Index, Barclays

        ex US IMI Index replaced the MSCI All Country World Index ex USA Index
        on July 1, 2008. The FTSE EPRA/NAREIT Global Real Estate Index replaced
        the Cohen & Steers Realty Majors Index on July 1, 2008.

        Treasury TIPS Index to the Barclays Capital U.S. Aggregate Bond Index
        and Barclays Capital U.S. Treasury Inflation Protected Securities
        (TIPS) Index (Series-L), respectively. Changes to these indexes are
        discussed further on page 21.

BGFA and BGI have in the past waived and may from time to time agree to waive
all or a portion of their fees or reimburse expenses to a Master Portfolio or
LifePath Portfolio. When they do so, the applicable LifePath Portfolio's
operating expenses are reduced so that the LifePath Portfolio's total return is
increased. These waivers and reimbursements may be discontinued at any time,
except as described in footnotes 1 and 2 to the Fees and Expenses table on the
immediately following page. In the absence of such waivers and/or
reimbursements, the applicable LifePath Portfolio's total return would be
lower.

Fees and Expenses

The table below describes the fees and expenses that you may pay if you buy and
hold Class S Shares of a LifePath Portfolio. The expenses are deducted from
each LifePath Portfolio's assets, which means you pay them indirectly. This
table does not reflect charges that may be imposed in connection with an
account in which you hold the shares. A broker-dealer or financial institution
maintaining the account in which you hold shares may charge a separate account,
service or transaction fee on the purchase or sale of Class S Shares that would
be in addition to the fees and expenses shown here.

The total annual operating expense ratios in the table and the example on the
next page reflect the expenses of the Class S Shares of each LifePath Portfolio
and its corresponding Master Portfolio and also reflect a weighted average of
the total operating expense ratios of the Underlying Funds in which each Master
Portfolio invests:

EXAMPLE

The example below is intended to help you compare the cost of investing in
Class S Shares of the LifePath Portfolios with the cost of investing in other
mutual funds. The example illustrates the cost you would have incurred on an
initial $10,000 investment in Class S Shares of each LifePath Portfolio over
the time periods shown. It assumes your investment earns an annual return of 5%
over the periods, that total operating expenses remain the same and that the
contractual fee waivers and reimbursements by BGFA and BGI are in effect for
two years.

THE LIFEPATH PORTFOLIOS DO NOT CHARGE A SALES LOAD OR OTHER FEE UPON
REDEMPTION. This means that your cost for each period would be the same whether
or not you sell your shares at the end of a period. Your actual costs may be
higher or lower than this hypothetical example:

A Further Discussion of Principal Investment Strategies

INTRODUCTION

Each LifePath Portfolio pursues a common strategy of allocating and
reallocating its assets among the Underlying Funds. The LifePath Portfolios
with longer time horizons invest a greater portion of their assets in
Underlying Funds that invest in equity securities, which provide a greater
potential to achieve higher returns over the long-term but have a greater risk
of short-term loss. In addition to investing in Underlying Funds, each LifePath
Portfolio may borrow, lend its portfolio securities to brokers, dealers and
financial institutions, and may invest the collateral in certain short-term
instruments either directly or through one or more joint accounts or money
market funds, as described in greater detail in the LifePath Portfolios'
combined Statement of Additional Information ("SAI").

The LifePath Portfolios with shorter time horizons invest a greater portion of
their assets in Underlying Funds that invest in bonds and money market
instruments, which typically offer reduced risk and price volatility, but
forego some potential returns. Accordingly, under normal circumstances, the
LifePath Portfolios with shorter time horizons have lower expected returns than
the LifePath Portfolios with longer time horizons. As each LifePath Portfolio
approaches its designated time horizon, it systematically seeks to reduce the
level of risk by allocating assets more conservatively among the Underlying
Funds. This systematic shift toward more conservative investments is designed
to reduce the risk of significant reductions in the value of an investment in a
LifePath Portfolio as it approaches its time horizon.

For example, the LifePath Retirement Portfolio has entered its "retirement
phase" and seeks to maximize returns consistent with the risk that an average
investor in retirement may be willing to accept. This does not mean, however,
that it invests exclusively, or primarily, in Underlying Funds that are money
market funds. Rather, because BGFA believes that most investors are still
willing to take some risks in pursuing returns even while drawing on their
investments, a portion of the LifePath Retirement Portfolio's assets will
continue to be allocated to Underlying Funds that are equity and bond funds, in
addition to Underlying Funds that are money market funds.

In determining the allocation of assets to the Underlying Funds, BGFA uses a
proprietary investment model that analyzes securities market data, including
risk, asset class correlations, and expected returns, to provide portfolio
allocations among the asset classes represented by the Underlying Funds. The
allocations are periodically monitored and rebalanced in an effort to maximize
expected return for a given level of risk. In managing the LifePath Portfolios,
BGFA focuses on long-term targets and objectives. The progression over time of
a LifePath Portfolio's asset allocation to more conservative asset classes is a
relatively steady process resulting in only gradual changes to the asset
allocation from quarter to quarter. The Underlying Funds invest in a mix of
equity securities, bonds and money market instruments. Certain Underlying Funds
invest in real estate investment trusts ("REITs"), foreign securities, emerging
markets, below investment-grade bonds and derivatives, which are subject to
additional risks, as described in the "Further Discussion of Principal Risk
Factors" section of this Prospectus. The investment model adjusts each LifePath
Portfolio's risk level by gradually making it more conservative as the year in
the LifePath Portfolio's name approaches, except for the LifePath Retirement
Portfolio, which is already in its most conservative phase.

THE UNDERLYING FUNDS

Two of the Underlying Funds - the Active Stock Master Portfolio and the
CoreAlpha Bond Master Portfolio (collectively, the "Underlying Master
Portfolios") - are diversified portfolios of Master Investment Portfolio
("MIP"). The Active Stock Master Portfolio seeks to provide long-term
appreciation of capital. BGFA invests the Active Stock Master Portfolio's
assets using a proprietary quantitative model that is designed to select stocks
based on an analysis of a wide range of company-specific factors. The CoreAlpha
Bond Master Portfolio seeks to provide a combination of income and capital
growth. BGFA invests the CoreAlpha Bond Master Portfolio's assets pursuant to a
systematic method that relies on

- --------------------------------------------------------------------------------
                                                                             13



proprietary quantitative models to allocate assets among various bond sectors
by evaluating each sector's relative value and risk-adjusted return.

The remaining Underlying Funds, other than the Barclays Global Investors Funds
("BGIF") Institutional Money Market Fund (the "Underlying Money Market Fund")
are exchange-traded funds ("ETFs") that are part of the iShares family of funds
("Underlying iShares Funds"). Each of the Underlying iShares Funds seeks
investment results that correspond generally to the performance, before fees
and expenses, of its underlying index. As a result, adverse performance of a
particular security in an Underlying iShares Fund's portfolio will ordinarily
not result in the elimination of the security from the Underlying iShares
Fund's portfolio. Each Underlying iShares Fund offers and issues iShares at
their net asset value per share only to certain institutional investors in
aggregations of a specified number of iShares, generally in exchange for a
basket of securities included in its underlying index, together with the
deposit of a specified cash payment. The iShares for these Underlying iShares
Funds are listed and traded on national securities exchanges and also may be
listed on certain non-U.S. exchanges. BGFA purchases iShares on behalf of the
Master Portfolios in the secondary market.

The relative weightings for each Master Portfolio in the various Underlying
Funds will vary over time, and BGFA is not required to invest any Master
Portfolio's assets in each of the Underlying Funds or in any particular
percentage in any given Underlying Fund. BGFA may add, eliminate or replace
Underlying Funds at any time.

Each Master Portfolio currently expects to invest in some or all of the
Underlying Funds described below:

ACTIVE STOCK MASTER PORTFOLIO

Seeks to provide long-term appreciation of capital. The Active Stock Master
Portfolio invests, under normal circumstances, at least 80% of its assets in
common stocks. The Active Stock Master Portfolio invests primarily in equity
securities of U.S. companies with market capitalizations similar to the range
of market capitalizations represented in the Standard & Poor's S&P 500 Index.
BGFA invests the Active Stock Master Portfolio's assets using a proprietary
quantitative model that is designed to select stocks based on an analysis of a
wide range of company-specific factors, such as relative values based on
earnings and cash flows; earnings quality as measured by the company's
financial condition and earnings reports; sentiment as expressed through
management and market participant behavior; and industry classification. BGFA
considers risk parameters in deciding upon the Active Stock Master Portfolio's
aggregate holdings, and factors trading costs into its stock selection process.


COREALPHA BOND MASTER PORTFOLIO

Seeks to provide a combination of income and capital growth. BGFA invests the
CoreAlpha Bond Master Portfolio's assets pursuant to a systematic method that
relies on proprietary quantitative models to allocate assets among various bond
sectors by evaluating each sector's relative value and risk-adjusted return.
BGFA's models also allocate assets among bonds of different maturities based on
yield characteristics and expectations. Specific investment selection decisions
are made on the basis of evaluations of relative value, credit quality and
other factors. The CoreAlpha Bond Master Portfolio invests, under normal
circumstances, at least 80% of its assets in bonds. For the purposes of this
strategy, "bonds" include the following: obligations issued or guaranteed by
the U.S. government, its agencies or instrumentalities; mortgage-backed
securities issued or guaranteed by the U.S. government, its agencies or
instrumentalities, including U.S. agency mortgage pass-through securities;
commercial mortgage-backed securities; debt obligations of U.S. corporations;
dollar-denominated debt obligations of foreign issuers; municipal securities;
and asset-backed securities. The CoreAlpha Bond Master Portfolio invests a
substantial portion of its assets in U.S.-registered, dollar-denominated bonds.
The CoreAlpha Bond Master Portfolio may invest in bonds of any maturity or
duration.

BGIF INSTITUTIONAL MONEY MARKET FUND

Seeks a high level of income consistent with liquidity and the preservation of
capital. The BGIF Institutional Money Market Fund invests in high-quality,
short-term money market instruments that include fixed-rate, floating-rate and
variable-rate debt securities. The BGIF Institutional Money Market Fund also
may invest in high-quality, short-term U.S.

and foreign government debt, including the debt of agencies and
instrumentalities, such as the Federal National Mortgage Association ("Fannie
Mae"), U.S. and foreign bank obligations, corporate obligations, repurchase
agreements and asset-backed securities.

UNDERLYING ISHARES FUNDS

In managing each of the Underlying iShares Funds, BGFA uses a representative
sampling index strategy. Representative sampling is an indexing strategy that
involves investing in a representative sample of securities that has an
investment profile similar to the underlying index. The securities selected are
expected to have, in the aggregate, investment characteristics (based on
factors such as market capitalization and industry weightings), fundamental
characteristics (such as return variability, duration, maturity or credit
ratings and yield) and liquidity measures similar to those of the applicable
underlying index. Underlying iShares Funds that use representative sampling may

A Further Discussion of Principal Risk Factors

In addition to the principal risks of investing described in the "Summary of
Principal Risk Factors" section of this Prospectus, the LifePath Portfolios
have the following risks:

GENERAL

The net asset value of each LifePath Portfolio's shares ("NAV") is neither
insured nor guaranteed, is not fixed and will fluctuate.

GENERAL RISKS APPLICABLE TO THE LIFEPATH PORTFOLIOS

EQUITY SECURITIES MARKET RISKS

The risks of investing in the equity securities market include both short-term
and prolonged price declines. The value of an equity security may decline in
value due to factors affecting equity securities markets generally or
particular industries represented in the markets. Equity securities may
underperform fixed-income investments and securities market indexes that track
other markets, segments and sectors. Equity securities of mid- to small-cap
companies tend to present greater risks than equity securities of large-cap
companies because they are generally more volatile and can be less liquid.

BOND INVESTMENT RISKS

The risks of fixed-income investing include short-term and prolonged price
declines because of a rise in interest rates, issuer quality considerations and
other economic considerations; however, such price declines in the bond market
have historically been less severe than stock declines.

CREDIT RISK

Credit risk is the risk that issuers or guarantors of debt instruments or the
counterparty to a derivatives contract, repurchase agreement or loan of
portfolio securities is unable or unwilling to make timely interest and/or
principal payments or to otherwise honor its obligations. There is the chance
that any of an Underlying Fund's holdings will have their credit ratings
downgraded or will default (fail to make scheduled interest or principal
payments), potentially reducing an Underlying Fund's income level and share
price. Debt instruments are subject to varying degrees of credit risk, which
may be reflected in credit ratings. Securities issued by the U.S. government
have limited credit risk. However, securities issued by U.S. government
agencies (such as U.S. agency mortgage pass-through securities) are not
necessarily backed by the full faith and credit of the U.S. government.

INTEREST RATE RISK

Interest rate risk is the risk that bond prices will decline over short or even
long periods due to rising market interest rates. All bonds, including those
issued by the U.S. government and its agencies, are subject to interest rate
risk. Their prices tend to move in the opposite direction from market interest
rate movements. When interest rates go up, bond prices tend to fall; when rates
fall, prices tend to rise. Bonds with longer maturities are affected more by
interest rate movements than bonds with shorter maturities, bonds with interest
rate reset provisions, notes or money market instruments. If prices throughout
the economy were to decline over time, resulting in "deflation," the principal
and income of inflation-protected bonds held by an Underlying Fund would likely
decline in price, which would result in losses for the Underlying Fund.
Mortgage-backed securities represent interests in or instruments backed by a
pool of loans secured by mortgages and asset-backed securities represent
interests in or instruments backed by a pool of loans secured by other assets.
Mortgage-backed securities and asset-backed securities are also subject to
prepayment risk and extension risk. Prepayment risk is the risk that during
periods of falling interest rates, an issuer of mortgages and other securities
may be able to repay principal prior to the security's maturity, causing the
Underlying Fund to have to

- --------------------------------------------------------------------------------
     22                                        BARCLAYS GLOBAL INVESTORS FUNDS



reinvest in securities with a lower yield. Extension risk is the risk that when
interest rates rise, certain mortgage-backed securities will be paid off
substantially more slowly than originally anticipated and the value of those
securities may fall sharply. Both prepayment risk and extension risk may result
in a decline to the Underlying Funds' income.

HIGH YIELD SECURITIES RISK

High yield securities risk is the risk that securities that are rated below
investment-grade (commonly referred to as "junk bonds," include those bonds
rated lower than "BBB-" by S&P, a division of The McGraw-Hill Companies, Inc.
and Fitch Rating Service Inc. or "Baa3" by Moody's(Reg. TM) Investor's
Services, Inc.) or are unrated but judged by an Underlying Fund to be of
comparable quality, at the time of purchase, may be more volatile than
higher-rated securities of similar maturity.

High yield securities may also be subject to greater levels of credit or
default risk than higher-rated securities. The value of high yield securities
can be adversely affected by overall economic conditions, such as an economic
downturn or a period of rising interest rates, and high yield securities may be
less liquid and more difficult to sell at an advantageous time or price or to
value than higher-rated securities.

NON-U.S. SECURITIES RISKS

Investments in the securities of non-U.S. issuers are subject to all the risks
of investing in the market of such issuers, including market fluctuations
caused by factors such as economic and political developments, changes in
interest rates and abrupt changes in stock prices. As a result of Underlying
Funds' investing in non-U.S. securities, the Fund may be subject to the risks
listed below. These risks may decrease the value of your investment:

[] Lower levels of liquidity and market efficiency;

[] Greater securities price volatility;

[] Exchange rate fluctuations and exchange controls;

[] Less availability of public information about issuers;

[] Imposition of withholding or other taxes;

[] Imposition of restrictions on the expatriation of funds or other assets of
the Underlying Fund;

[] Higher transaction and custody costs and delays in settlement procedures;

[] Difficulties in enforcing contractual obligations;

[] Substantial government involvement in the economy;

[] Higher rates of inflation;

[] Greater social, economic and political uncertainty, the risk of
 nationalization or expropriation of assets and risk of war;

[] Lower levels of regulation of the securities markets;

[] Different accounting, disclosure and reporting requirements; and

[] Legal principles relating to corporate governance, director's fiduciary
 duties and liabilities and stockholder's rights in markets in which the
 Underlying Funds invest may differ and/or may not be as extensive or
 protective as those that apply in the United States.

Investments in non-U.S. securities may be made by an Underlying Fund directly
or through investments in American Depositary Receipts ("ADRs") and other
similar investments. ADRs are receipts for shares of non-U.S. stocks held on
deposit in U.S. banks or banks of major European countries. The receipts trade
on the U.S. or local European stock markets as would normal stocks, entitling
their owners to the dividends and capital gains earned by the real shares
stored in bank vaults. ADRs reduce some of the risks of foreign investing
because a large, liquid market generally exists

- --------------------------------------------------------------------------------
                                                                             23



and U.S. trading and settlement practices reduce currency, custodial and other
operational risks. Similar investments (European and Global Depositary
Receipts) are receipts for stock deposited in non-U.S. bank and trust
companies, trade across foreign and domestic markets, and can involve different
or greater risks than ADRs.

EMERGING MARKETS RISK

Some foreign markets are considered to be emerging markets. Investment in these
emerging markets is subject to a greater risk of loss than investments in a
developed market. This is due to, among other things, greater market
volatility, lower trading volume, political and economic instability, greater
risk of market shut down and more governmental limitations on foreign
investment policy than those typically found in a developed market.

MODEL RISK

Although the quantitative model used to manage the Master Portfolios' assets
has been developed and refined over many years, neither the Master Portfolios
nor BGFA can offer any assurance that the recommended allocation will either
maximize returns or minimize risks, nor can the Master Portfolios or BGFA offer
assurance that a recommended allocation will be the appropriate allocation in
all circumstances for every investor with a particular time horizon.

REAL ESTATE INVESTMENT RISK

Investment in equity securities in the real estate sector is subject to many of
the same risks associated with the direct ownership of real estate, such as
adverse changes in national, state or local real estate conditions (resulting
from, for example, oversupply of or reduced demand for space and changes in
market rental rates); obsolescence of properties; changes in the availability,
cost and terms of mortgage funds; and the impact of tax, environmental, and
other laws.

DERIVATIVES

Derivatives include, among other instruments, futures contracts, options on
futures contracts, other types of options that may be exchange-traded or traded
over-the-counter, indexed and inverse floating-rate securities, and swap
agreements. Derivatives are financial instruments whose values are derived, at
least in part, from the prices of other securities or specified assets, indexes
or rates. Some derivatives may be more sensitive than direct securities to
changes in interest rates or sudden market moves. Some derivatives also may be
susceptible to fluctuations in yield or value due to their structure or
contract terms.

PASSIVE INVESTMENT RISK

Because BGFA does not select individual companies in the underlying indexes for
the Underlying iShares Funds, those Underlying iShares Funds may hold stocks in
companies that present risks that an investment adviser researching individual
stocks might seek to avoid.

SECURITY SELECTION RISK

For each of Active Stock Master Portfolio and CoreAlpha Bond Master Portfolio,
BGFA bases security selection on its analysis of securities and therefore each
of these Master Portfolios is subject to the risk that poor security selection
will result in underperformance of the Master Portfolio in comparison with
other investment vehicles with similar investment objectives and strategies.

SECURITIES LENDING RISK

The LifePath Portfolios may also lend portfolio securities to borrowers that
provide collateral at least equal to the current market value of the securities
loaned, plus accrued interest or dividends. BGI acts as securities lending
agent for, and is compensated by, the LifePath Portfolios. Securities lending
collateral is generally reinvested in a joint account or money market funds,
including those advised by BGFA. Risks related to securities lending include
operational, credit, legal, counterparty and market risk, as well as investment
risks related to the collateral and risk of loss if the collateral is
liquidated.

     24                                        BARCLAYS GLOBAL INVESTORS FUNDS



CONCENTRATION RISK

To the extent that an underlying index of an Underlying iShares Fund is
concentrated in the securities of companies, a particular market industry,
group of industries, sector or asset class countries, regions or groups of
countries, that Underlying iShares Fund may be adversely affected by the
performance of those securities, may be subject to increased price volatility
and may be more susceptible to adverse economic, market, political or
regulatory occurrences affecting that market, industry, group of industries,
sector or asset class country, region or group of countries.

MARKET TRADING RISKS

The Underlying iShares Funds are subject to certain additional risks due to
their shares being listed and traded on securities exchanges. There can be no
assurance that an active trading market for these particular ETFs will develop
or be maintained. Trading in ETFs may be halted because of market conditions or
for reasons that, in the view of the listing exchange, make trading in ETFs
inadvisable. In addition, trading in ETFs is subject to trading halts caused by
extraordinary market volatility pursuant to "circuit breaker" rules. There can
be no assurance that the requirements necessary to maintain the listing of ETFs
will continue to be met or will remain unchanged. An ETF may trade at, above or
below its NAV. The NAV of an ETF will fluctuate with changes in the market
value of its holdings. The trading price of an ETF will generally fluctuate in
accordance with changes in its NAV, as well as market supply and demand.

TRACKING ERROR RISK

Imperfect correlation between an Underlying iShares Fund's securities and those
in its underlying index, rounding of prices, changes to the underlying index
and regulatory requirements, may cause "tracking error," which is measured as
the divergence of the Underlying iShares Fund's performance from that of its
underlying index. Tracking error also may result because an Underlying iShares
Fund incurs fees and expenses while its underlying index does not incur the
same expenses.

Management of the LifePath Portfolios

INVESTMENT ADVISER

Each LifePath Portfolio is a feeder fund that invests all of its assets in a
Master Portfolio that has a substantially identical investment objective,
strategies and policies as the LifePath Portfolio. The Master Portfolios, in
turn, invest in a combination of the Underlying Funds. BGFA, a registered
investment adviser, serves as investment adviser to each Master Portfolio, and
also serves as investment adviser to each Underlying Fund, with the exception
of the Underlying Money Market Fund, which invests in a Master Portfolio
advised by BGFA. BGFA manages the investing of the Master Portfolios' assets
and provides the Master Portfolios with investment guidance and policy
direction in connection with daily portfolio management, subject to the
supervision of the Master Portfolios' Board of Trustees. For its services to
the Master Portfolios, BGFA is entitled to receive an annual advisory fee of
0.35% of each Master Portfolio's average daily net assets.

For its services to the Underlying Funds, BGFA receives fees that differ from
the fees described for the LifePath Portfolios in this Prospectus. BGFA
provides investment advisory services for the Underlying Funds that differ from
the investment advisory services it provides for the Master Portfolios. For
those services, BGFA receives investment advisory fees from the Underlying
Funds. In addition, BGI provides administration services to certain of the
Underlying Funds and, for those services, may receive administration fees from
those Underlying Funds. BGFA has contractually agreed to waive its management
fees at the Master Portfolio level in an amount equal to advisory and
administration fees, if any, paid by the Underlying Funds to BGFA and BGI,
respectively, through April 30, 2011.

BGFA is located at 400 Howard Street, San Francisco, CA 94105. It is a
wholly-owned subsidiary of BGI, which in turn is a majority-owned subsidiary of
Barclays Bank PLC. As of February 28, 2009, BGI and its affiliates, including
BGFA, provided investment advisory services for assets in excess of $1.36
trillion. BGI, BGFA, Barclays Global Investors Services, Barclays Bank PLC and
their affiliates deal, trade and invest for their own accounts in the types of
securities in which the Master Portfolios invest.

A discussion regarding the basis for the Master Portfolios' Board of Trustees'
approval of the investment advisory agreements with BGFA is available in each
LifePath Portfolio's semi-annual report for the six-month period ending June
30.

HOW TO BUY SHARES

[] PLAN PARTICIPANT. Invest through payroll deductions or make a direct
 contribution by rolling over an amount from another 401(k) plan or from a
 rollover IRA (make arrangements through your employer). If you are investing
 through an IRA, your IRA trustee or custodian is responsible for properly
 transmitting your purchase order to State Street Bank and Trust Company
 ("State Street"), the LifePath Portfolios' custodian, transfer agent and
 dividend disbursing agent. Your plan or IRA may impose an earlier deadline for
 purchase or redemption orders than the LifePath Portfolios, as described
 below.

[] TAX-DEFERRED INVESTOR. Invest through a custodian as provided in your
 benefit plan documents. Your custodian, plan sponsor or administrator is
 responsible for properly transmitting your purchase order to State Street and
 may impose an earlier deadline for purchase and redemption orders than the
 LifePath Portfolios, as described below.

You may buy LifePath Portfolio shares without paying a sales charge. Your
purchase order must be received in proper form, as determined by State Street
or an intermediary pursuant to an appropriate agreement, by the close of
regular trading on the New York Stock Exchange ("NYSE") (generally 4:00 p.m.
Eastern Time) (or if regular trading on the NYSE closes early, at such closing
time) on any day the LifePath Portfolios are open (a "Business Day") to
purchase shares at that day's NAV. Orders received after the close of regular
trading on the NYSE will be executed on the next Business Day. The LifePath
Portfolios are generally open Monday through Friday and are generally closed on
weekends and any day on which the NYSE is closed.

Each LifePath Portfolio reserves the right to suspend or discontinue the offer
and sale of its shares and reject or cancel any purchase order for any reason.

Purchases generally must be made in U.S. dollars. You may be charged for any
costs incurred in connection with a purchase order that has been placed but for
which the LifePath Portfolio has not received full payment.

HOW TO SELL SHARES

[] PLAN PARTICIPANT AND TAX-DEFERRED INVESTOR. Contact your plan sponsor,
 administrator or custodian, who is responsible for properly transmitting your
 sale order to State Street.

You may sell LifePath Portfolio shares without paying a sales charge. Your
order to sell shares must be received in proper form, as determined by State
Street or an intermediary pursuant to an appropriate agreement, by the close of
regular trading on the NYSE (generally 4:00 p.m. Eastern Time) (or if regular
trading on the NYSE closes early, at such closing time) on any Business Day to
sell shares at that day's NAV. Orders received after the close of regular
trading on the NYSE will be executed on the next Business Day.

The LifePath Portfolios generally remit the proceeds from a sale the next
Business Day after receiving a properly executed order to sell and no longer
than seven days after the sale. Each LifePath Portfolio reserves the right to
suspend your right of redemption and to delay delivery of your redemption
proceeds up to seven days, as permitted under applicable law. Each LifePath
Portfolio further reserves the right to automatically redeem your shares and
close your account for any reason, subject to applicable law, and send you the
proceeds, which would reflect the NAV on the day the LifePath Portfolio
automatically redeems your shares. For example, a LifePath Portfolio may
automatically redeem your shares to reimburse the LifePath Portfolio for any
losses sustained by reason of your failure to make full payment for shares
purchased or to collect any charge relating to a transaction effected for your
benefit that is applicable to the LifePath Portfolio's shares as provided from
time to time in this Prospectus.

In addition, each LifePath Portfolio reserves the right to send your redemption
proceeds in the form of securities from its Master Portfolio.

Upon redemption, the identity of the holder of the account to which the
proceeds are being sent may need to be verified.

CALCULATING THE LIFEPATH PORTFOLIOS' SHARE PRICE

Each LifePath Portfolio's share price (also known as a LifePath Portfolio's
NAV) is calculated by dividing the value of the net assets of the LifePath
Portfolio (I.E., the value of its total assets less total liabilities) by the
total number of outstanding shares of the LifePath Portfolio, generally rounded
to the nearest cent.

Each LifePath Portfolio's NAV is calculated at the close of regular trading on
the NYSE (generally, 4:00 p.m. Eastern Time) on any Business Day. If regular
trading on the NYSE closes early, the time for calculating each LifePath
Portfolio's NAV and the deadline for share transactions will be accelerated to
the earlier closing time. The NAV of each LifePath Portfolio is calculated
based on the net asset value of the Master Portfolio in which the LifePath
Portfolio invests. The LifePath Portfolios' SAI includes a description of the
methods for valuing the Master Portfolios' investments, including a description
of the circumstances in which the Master Portfolios' investments would be
valued using fair value pricing and the effects of using fair value pricing.

LIFEPATH PORTFOLIO DISTRIBUTIONS

The LifePath Portfolios distribute their net investment income to shareholders
quarterly. The LifePath Portfolios distribute their net realized capital gains,
if any, to shareholders at least annually. Distributions payable to you will be
automatically reinvested in additional Class S Shares of your LifePath
Portfolio, unless you have elected to receive distribution payments in cash.

FREQUENT TRADING IN LIFEPATH PORTFOLIO SHARES

Frequent purchases and redemptions of mutual fund shares ("frequent trading")
may have a detrimental effect on a fund and its shareholders. Depending on
various factors, such as the size of the fund's investment portfolio and the
amount of assets maintained in cash, frequent trading may harm the performance
of the fund by interfering with the implementation of its investment strategies
and/or increasing transaction costs and taxes, and/or may dilute the value of
fund shares held by long-term investors. Frequent trading may include activity
that appears to attempt to take advantage of a potential arbitrage opportunity
presented by a lag between a change in the value of a fund's investment
portfolio securities after the close of the primary markets for those portfolio
securities and the reflection of that change in the fund's net asset value
("market timing").

Each LifePath Portfolio invests only in interests of its Master Portfolio, and
the Boards of Trustees of the Master Portfolios and the LifePath Portfolios
have each considered the issues of frequent trading and market timing.

The Master Portfolios' Board of Trustees has adopted a policy of not monitoring
for possible market timing activity because the Master Portfolios' holdings are
valued as of the same time that the net asset value of the Master Portfolios is
calculated (generally 4:00 p.m. Eastern Time), which eliminates the potential
arbitrage opportunity presented by a lag between a change in the value of the
Master Portfolios' holdings and the reflection of that change in the Master
Portfolios' respective net asset values. The Master Portfolios' Board of
Trustees has not adopted a policy of monitoring for other forms of frequent
trading because daily flows into and out of the Master Portfolios are
aggregated, and the process of aggregation is expected to reduce the potential
for frequent trading to disrupt the implementation of the Master Portfolios'
investment strategies.

The LifePath Portfolios' Board of Trustees has not adopted a policy of
monitoring for market timing or other frequent trading activity in the LifePath
Portfolios in light of the nature of the LifePath Portfolios' investment in
Master Portfolios, the policies of the Master Portfolios, as described in the
preceding paragraphs, and the historical nature of flows into and out of the
LifePath Portfolios.

BGI's ability to monitor trades that are placed by participants in plans that
are shareholders in the LifePath Portfolios or other shareholders in the
LifePath Portfolios that trade through omnibus accounts maintained by
intermediaries will be severely limited to the extent BGI does not receive
transaction information showing individual investment decisions. Upon request
by the LifePath Portfolios, intermediaries are required to provide certain
transaction information that may enable the LifePath Portfolios to identify
trading activity that is potentially harmful to the LifePath Portfolios. The

LifePath Portfolios may, but do not have the obligation to, respond to any
potentially harmful trading activity that is identified. In the event any
potentially harmful trading activity is identified, responses may include the
imposition of trading restrictions, the rejection of purchases, or such other
steps the LifePath Portfolios determine are appropriate. Intermediaries'
ability to impose restrictions on the trading practices of their clients may,
however, be affected by legal or technological limitations.

TAXES

The following discussion regarding U.S. federal income taxes is based upon laws
in effect as of the date of this Prospectus and summarizes only some of the
important U.S. federal income tax considerations affecting the LifePath
Portfolios and their U.S. shareholders. This discussion is not intended as a
substitute for careful tax planning. Please see the SAI for additional U.S.
federal income tax information.

Shareholders that are exempt from U.S. federal income tax, such as retirement
plans that are qualified under Section 401 of the U.S. Internal Revenue Code of
1986, as amended (the "Code"), generally are not subject to U.S. federal income
tax on fund dividends or distributions or on sales of LifePath Portfolio
shares. However, in the case of LifePath Portfolio shares held through a
non-qualified deferred compensation plan, fund dividends and distributions
received by the plan and sales of LifePath Portfolio shares by the plan
generally will be taxable to the employer sponsoring such plan in accordance
with U.S. federal income tax laws governing deferred compensation plans.

A plan participant whose retirement plan invests in LifePath Portfolio shares
generally is not taxed on LifePath Portfolio dividends or distributions
received by the plan or on sales of LifePath Portfolio shares by the plan for
U.S. federal income tax purposes. However, distributions to plan participants
from a retirement plan generally are taxable to plan participants as ordinary
income. Special rules may also apply to such distributions. Plan participants
should contact their own tax advisers for more information.

You must provide your correct social security number or other taxpayer
identification number to the LifePath Portfolio along with any certifications
required by the Internal Revenue Service when you open an account.

MASTER/FEEDER MUTUAL FUND STRUCTURE

The LifePath Portfolios do not have their own investment adviser. Instead, each
LifePath Portfolio invests all of its assets in a separate mutual fund, called
a Master Portfolio, that has a substantially identical investment objective,
strategies and policies as the LifePath Portfolio. BGFA serves as investment
adviser to each Master Portfolio. The Master Portfolios may accept investments
from other feeder funds. Certain actions involving other feeder funds, such as
a substantial withdrawal, could affect the Master Portfolios and, therefore,
the LifePath Portfolios.

FEEDER FUND EXPENSES

Feeder funds, including the LifePath Portfolios, bear their respective Master
Portfolio's expenses in proportion to the amount of assets each invests in the
Master Portfolio. Each feeder fund can set its own transaction minimums,
fund-specific expenses and conditions.

FEEDER FUND RIGHTS

Under the master/feeder structure, the LifePath Portfolios' Board of Trustees
retains the right to withdraw a LifePath Portfolio's assets from its Master
Portfolio if it believes doing so is in the best interests of the LifePath
Portfolio's shareholders. If the Board of Trustees decides to withdraw a
LifePath Portfolio's assets, it would then consider whether the LifePath
Portfolio should hire its own investment adviser, invest in another master
portfolio or take other action.

FUND OF FUNDS

The Master Portfolios do not invest directly in a portfolio of securities.
Instead, they invest in the Underlying Money Market Fund and other Underlying
Funds that are also advised by BGFA. Each Master Portfolio charges for its own
direct expenses, in addition to bearing a PRO RATA share of the expenses
charged by the Underlying Funds in which it invests.

Financial Highlights

The financial tables in this section are intended to help investors understand
the financial performance of the Class S Shares of each LifePath Portfolio
since inception. Certain information reflects financial results for a single
Class S Share of each LifePath Portfolio. The total returns in the tables
represent the rate of return that an investor would have earned (or lost) on an
investment in Class S Shares of a given LifePath Portfolio, assuming
reinvestment of all distributions. The information has been audited by
PricewaterhouseCoopers LLP, whose report, along with the LifePath Portfolios'
financial statements, is included in the LifePath Portfolios' annual report.
You may obtain copies of the annual report, at no cost, by calling

invest. On June 16, 2009, Barclays PLC, the ultimate parent company of BGI and
the Adviser, accepted a binding offer and entered into an agreement to sell its
interests in the Adviser, BGI and certain affiliated companies, to BlackRock,
Inc., (the "BlackRock Transaction"). The BlackRock Transaction is subject to
certain regulatory approvals, as well as other conditions to closing.

Under the Investment Company Act of 1940, as amended, completion of the
BlackRock Transaction will cause the automatic termination of each Master
Portfolio's current investment advisory agreement with the Adviser. In order
for the investment management of each Master Portfolio and Fund to continue
uninterrupted, the Board of Trustees of the Master Portfolios (the "Master
Portfolios' Board") will be asked to approve a new investment advisory
agreement for each Master Portfolio. If approved by the Master Portfolios'
Board, the new investment advisory agreements will be submitted for approval by
the investors in the Master Portfolios, including the Funds. Each Fund will in
turn call a meeting of its shareholders at which shareholders will vote to
instruct the Fund how to vote on the applicable Master Portfolio's new
investment advisory agreement.

If you have any additional questions, please call 1-877-BGI-1544
(1-877-244-1544) (toll-free).

The information in this section of the Supplement updates information in, and
should be read in conjunction with, the Prospectus for each of LifePath 2010
Portfolio and LifePath Retirement Portfolio.

On May 20, 2009, the Board of Trustees of the Barclays Global Investors Funds
approved an Agreement and Plan of Reorganization pursuant to which shareholders
of each class of shares of the LifePath 2010 Portfolio would become
shareholders of the corresponding class of shares of the LifePath Retirement
Portfolio, another series of the Barclays Global Investment Funds. The
reorganization is expected to close on or about November 20, 2009 (the "Closing
Date"), at which time the LifePath 2010 Portfolio will be approaching its
target date and the investment objective, policies, strategies and restrictions
of the LifePath 2010 Portfolio will have aligned with those of the LifePath
Retirement Portfolio. The closing of the reorganization is subject to certain
conditions. The reorganization does not require any action on the part of
shareholders and is expected to be free of any tax consequences to shareholders.

Prior to the reorganization, the LifePath 2010 Portfolio will continue to
operate as described in each Prospectus and will continue to accept investments
from new and existing shareholders. Further detail regarding the reorganization
will be distributed to shareholders in advance of the Closing Date.

                           Master Investment Portfolio
                      LifePath Retirement Master Portfolio
                                    Pro Forma
               Notes to Combining Financial Statements (Unaudited)
                                  June 30, 2009

1) Description of the Fund

Master Investment Portfolio ("MIP") is registered under the Investment Company
Act of 1940, as amended (the "1940 Act"), as an open-end series management
investment company organized as a Delaware statutory trust.

These financial statements relate only to the LifePath Retirement and LifePath
2010 Master Portfolios, (each, a "Master Portfolio," collectively, the "Master
Portfolios"). Each of the LifePath Retirement and LifePath 2010 Master
Portfolios seeks to achieve its investment objective by investing in a
combination of equity securities, bond and money market funds (the "Underlying
Funds") in proportions suggested by its own comprehensive investment strategy.
The Underlying Funds are advised by Barclays Global Fund Advisors ("BGFA"), and
include the Active Stock and CoreAlpha Bond Master Portfolios, the Barclays
Global Investors Funds Institutional Money Market Fund and exchange-traded funds
in the iShares(R) family of funds.

Pursuant to MIP's organizational documents, the Master Portfolios' officers and
trustees are indemnified against certain liabilities that may arise out of the
performance of their duties to the Master Portfolios. Additionally, in the
normal course of business, the Master Portfolios enter into contracts with
service providers that contain general indemnification clauses. The Master
Portfolios' maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Master Portfolios that have
not yet occurred.

2) Basis of Combination

The accompanying pro forma financial statements are presented to show the effect
of the proposed acquisition of the LifePath 2010 Master Portfolio, (the "Target
Fund") by LifePath Retirement Master Portfolio, (the "Acquiring Fund") as if
such acquisition had taken place as of June 30, 2009.

Under the terms of the Agreement and Plan of Reorganization (the "Agreement"),
the combination of the Target Fund and the Acquiring Fund will be accounted for
by the method of accounting for tax-free mergers of investment companies. The
acquisition would be accomplished by a transfer of the net assets of the Target
Fund in exchange for shares of the Acquiring Fund at net asset value. The
Acquiring Fund will assume all of the liabilities of the Target Fund. The
statement of assets and liabilities and the related statement of operations of
the Target Fund and the Acquiring Fund have been combined as of and for the
twelve months ended June 30, 2009. Following the acquisition, the Acquiring Fund
will be the accounting survivor. In accordance with accounting principles
generally accepted in the United States of America ("U.S. GAAP"), the historical
cost of investment securities will be carried forward to the surviving fund and
the results of operations for precombination periods of the surviving fund will
not be restated.

The accompanying pro forma financial statements should be read in conjunction
with the financial statements of the Acquiring Fund and the Target Fund included
in their respective semi-annual reports dated June 30, 2009.

The following notes refer to the accompanying pro forma financial statements as
if the

                                        8




above-mentioned acquisition of the Target Fund by the Acquiring Fund had taken
place as of June 30, 2009.

3) Security Valuation

The securities and other assets of each Master Portfolio are valued pursuant to
the pricing policy and procedures approved by the Board of Trustees of MIP (the
"Board"). The Master Portfolios are subject to the provisions of Financial
Accounting Standards Board ("FASB") Statement of Financial Accounting Standards
No. 157 ("FAS 157"), "Fair Value Measurements." This standard establishes a fair
value hierarchy that prioritizes the inputs to valuation techniques used to
measure fair value into three broad levels. Inputs may be based on independent
market data ("observable inputs") or they may be internally developed
("unobservable inputs"). The hierarchy gives the highest priority to unadjusted
quoted prices in active markets for identical assets or liabilities (Level 1
measurements) and the lowest priority to unobservable inputs (Level 3
measurements). The three levels of the fair value hierarchy under FAS 157 are as
follows:

Level 1 - Inputs that reflect unadjusted quoted prices in active markets for
identical assets or liabilities that the Master Portfolio has the ability to
access at the measurement date (a "Level 1 Price");

Level 2 - Inputs other than quoted prices included within Level 1 that are
observable for the asset or liability either directly or indirectly, including
quoted prices for similar assets or liabilities in active markets, quoted prices
for identical or similar assets or liabilities in markets that are not
considered to be active, inputs other than quoted prices that are observable for
the asset or liability, and inputs that are derived principally from or
corroborated by observable market data by correlation or other means (a "Level 2
Price");

Level 3 - Inputs that are unobservable for the asset or liability (a "Level 3
Price").

The availability of observable inputs can vary from security to security and is
affected by a wide variety of factors, including, for example, the type of
security, whether the security is new and not yet established in the
marketplace, the liquidity of markets, and other characteristics particular to
the security. Inputs may include price information, volatility statistics,
specific and broad credit data, liquidity statistics, and other factors. To the
extent that valuation is based on models or inputs that are less observable or
unobservable in the market, the determination of fair value requires more
judgment. Accordingly, the degree of judgment exercised in determining fair
value is greatest for instruments categorized in Level 3 of the fair value
hierarchy.

The level of a value determined for a financial instrument within the fair value
hierarchy is based on the lowest level of any input that is significant to the
fair value measurement in its entirety. The categorization of a value determined
for a financial instrument within the hierarchy is based upon the pricing
transparency of the instrument and does not necessarily correspond to the Master
Portfolios' perceived risk of that instrument.

                                        9




Investments whose values are based on quoted market prices in active markets,
and whose values are therefore classified as Level 1 Prices, include active
listed equities and certain U.S. government securities. The Master Portfolios do
not adjust the quoted price for such instruments, even in situations where the
Master Portfolios hold a large position and a sale could reasonably impact the
quoted price.

Investments that trade in markets that are not considered to be active, but
whose values are based on inputs such as quoted market prices, dealer quotations
or valuations provided by alternative pricing sources supported by observable
inputs are classified within Level 2. These generally include certain U.S.
government and sovereign obligations, most government agency securities,
investment-grade corporate bonds, certain mortgage products, less liquid listed
equities, and state, municipal and provincial obligations. As Level 2
investments include positions that are not traded in active markets and/or are
subject to transfer restrictions, valuations may be adjusted to reflect
illiquidity and/or non-transferability, which are generally based on available
market information.

Investments whose values are classified as Level 3 Prices have significant
unobservable inputs, as they may trade infrequently or not at all. Investments
whose values are classified as Level 3 Prices may include unlisted securities
related to corporate actions, securities whose trading have been suspended or
which have been de-listed from their primary trading exchange, less liquid
corporate debt securities (including distressed debt instruments),
collateralized debt obligations, and less liquid mortgage securities (backed by
either commercial or residential real estate). When observable prices are not
available for these securities, the Master Portfolios use one or more valuation
techniques (e.g., the market approach or the income approach) for which
sufficient and reliable data is available. Within Level 3 of the fair value
hierarchy, the use of the market approach generally consists of using comparable
market transactions, while the use of the income approach generally consists of
the net present value of estimated future cash flows, adjusted as appropriate
for liquidity, credit, market and/or other risk factors.

The inputs used by the Master Portfolios in estimating the value of Level 3
Prices may include the original transaction price, recent transactions in the
same or similar instruments, completed or pending third-party transactions in
the underlying investment or comparable issuers, and changes in financial ratios
or cash flows. Level 3 Prices may also be adjusted to reflect illiquidity and/or
non-transferability, with the amount of such discount estimated by the Master
Portfolios in the absence of market information. The fair value measurement of
Level 3 Prices does not include transaction costs that may have been capitalized
as part of the security's cost basis. Assumptions used by the Master Portfolios
due to the lack of observable inputs may significantly impact the resulting fair
value and therefore the Master Portfolios' results of operations.

Fair value pricing could result in a difference between the prices used to
calculate a Master Portfolio's net assets and the prices used by the Master
Portfolio's underlying index, which in turn, could result in a difference
between the Master Portfolio's performance and the performance of the Master
Portfolio's underlying index.

4) Unaudited Pro Forma Adjustments

LifePath 2010 Master Portfolio expenses were adjusted assuming LifePath
Retirement Master Portfolio's fee structure was in effect for the twelve months
ended June 30, 2009.

5) Use of Estimates

The following significant accounting policies are consistently followed by MIP
in the preparation of its financial statements in conformity with U.S. GAAP. The
preparation of financial statements in conformity with U.S. GAAP requires
management to make certain estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosures of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
revenue and expenses during the 12 months ended June 30, 2009. Actual results
could differ from those estimates.

6) Federal Income Taxes

In general, MIP believes that each Master Portfolio has and will continue to be
operated in a manner so as to qualify it as a non-publicly traded partnership
for federal income tax purposes. Provided that each such Master Portfolio so
qualifies, it will not be subject to any federal income tax on its income and
gains (if any). However, each interestholder in such a Master Portfolio will be
taxed on its distributive share of the Master Portfolio's taxable income in
determining its

                                       11




federal income tax liability. As a non-publicly traded partnership for federal
income tax purposes, each such Master Portfolio will be deemed to have "passed
through" to its interestholders any interest, dividends, gains or losses of the
Master Portfolio for such purposes. The determination of such share will be made
in accordance with the Internal Revenue Code of 1986, as amended (the "Code"),
and regulations promulgated thereunder.

It is intended that each Master Portfolio's assets, income and distributions
will be managed in such a way that an entity electing and qualifying as a
"regulated investment company" under the Code can continue to so qualify by
investing substantially all of its assets through the Master Portfolio, provided
that the regulated investment company meets other requirements for such
qualifications not within the control of the Master Portfolio (e.g.,
distributing at least 90% of the regulated investment company's "investment
company taxable income" annually).

As of June 30, 2009, the gross unrealized appreciation and gross unrealized
depreciation based on cost for federal income tax purposes for the Master
Portfolios were as follows:



                                                                Gross          Gross

(a)  Tax cost information does not include investments in the underlying Master
     Portfolios.

Management has reviewed the tax positions as of June 30, 2009, inclusive of the
prior three open tax return years and has determined that no provision for
income tax is required in the Master Portfolios' financial statements.

                         Barclays Global Investors Funds
                          LifePath Retirement Portfolio
                                    Pro Forma
               Notes to Combining Financial Statements (Unaudited)
                                  June 30, 2009

1) Description of the Fund

Barclays Global Investors Funds (the "Trust"), a Delaware statutory trust, is
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as an open-end series management investment company. The Trust, formerly
known as Barclays Global Investors Funds, Inc. was redomiciled from a Maryland
corporation to a Delaware statutory trust effective January 11, 2002.

These financial statements relate only to the LifePath Retirement and LifePath
2010 Portfolios, (each, a "LifePath Portfolio," collectively, the "LifePath
Portfolios").

The LifePath Portfolios offer three classes of shares: Class I, Class R and
Class S. All classes of shares have equal rights to assets and earnings, and
differ principally in administration and distribution fees.

Pursuant to the Trust's organizational documents, the LifePath Portfolios'
officers and trustees are indemnified against certain liabilities that may arise
out of the performance of their duties to the LifePath Portfolios. Additionally,
in the normal course of business, the LifePath Portfolios enter into contracts
with service providers that contain general indemnification clauses. The
LifePath Portfolios' maximum exposure under these arrangements is unknown as
this would involve future claims that may be made against the LifePath
Portfolios that have not yet occurred.

2) Basis of Combination

The accompanying pro forma financial statements are presented to show the effect
of the proposed acquisition of the LifePath 2010 Portfolio, (the "Target Fund")
by the LifePath Retirement Portfolio, (the "Acquiring Fund") as if such
acquisition had taken place as of June 30, 2009.

Under the terms of the Agreement and Plan of Reorganization (the "Agreement"),
the combination of the Target Fund and the Acquiring Fund will be accounted for
by the method of accounting for tax-free mergers of investment companies. The
acquisition would be accomplished by a transfer of the net assets of the Target
Fund in exchange for shares of the Acquiring Fund at net asset value. The
Acquiring Fund will assume all of the liabilities of the Target Fund. The
statement of assets and liabilities and the related statement of operations of
the Target Fund and the Acquiring Fund have been combined as of and for the
twelve months ended June 30, 2009. Following the acquisition, the Acquiring Fund
will be the accounting survivor. In accordance with accounting principles
generally accepted in the United States of America ("U.S. GAAP"), the historical
cost of investment securities will be carried forward to the surviving fund and
the results of operations for precombination periods of the surviving fund will
not be restated.

The accompanying pro forma financial statements should be read in conjunction
with the financial statements of the Acquiring Fund and the Target Fund included
in their respective semi-annual reports dated June 30, 2009.

The following notes refer to the accompanying pro forma financial statements as
if the above-mentioned acquisition of the Target Fund by the Acquiring Fund had
taken place as of June 30, 2009.

                                       15




3) Security Valuation

The LifePath Portfolios are subject to the provisions of Financial Accounting
Standards Board ("FASB") Statement of Financial Accounting Standards No. 157
("FAS 157"), "Fair Value Measurements." This standard establishes a fair value
hierarchy that prioritizes the inputs to valuation techniques used to measure
fair value into three broad levels. Inputs may be based on independent market
data ("observable inputs") or they may be internally developed ("unobservable
inputs"). The hierarchy gives the highest priority to unadjusted quoted prices
in active markets for identical assets or liabilities (Level 1 measurements) and
the lowest priority to unobservable inputs (Level 3 measurements). The three
levels of the fair value hierarchy under FAS 157 are as follows:

..    Level 1 - Inputs that reflect unadjusted quoted prices in active markets
     for identical assets or liabilities that the LifePath Portfolio has the
     ability to access at the measurement date;

..    Level 2 - Inputs other than quoted prices included within Level 1 that are
     observable for the asset or liability either directly or indirectly,
     including quoted prices for similar assets or liabilities in active
     markets, quoted prices for identical or similar assets or liabilities in
     markets that are not considered to be active, inputs other than quoted
     prices that are observable for the asset or liability, and inputs that are
     derived principally from or corroborated by observable market data by
     correlation or other means;

..    Level 3 - Inputs that are unobservable for the asset or liability.

Each LifePath Portfolio invests all of its assets in a separate series (each, a
"Master Portfolio") of Master Investment Portfolio ("MIP"). Each Master
Portfolio has the same or substantially similar investment objective as its
corresponding LifePath Portfolio. The value of each LifePath Portfolio's
investment in its corresponding Master Portfolio reflects that LifePath
Portfolio's interest in the net assets of that Master Portfolio (49.76% and
49.34% for the LifePath Retirement and LifePath 2010 Portfolios, respectively,
as of June 30, 2009).

The determination of what constitutes an "observable" input may require
significant judgment by the LifePath Portfolios. As of June 30, 2009, each
LifePath Portfolio's investment in its corresponding Master Portfolio was
classified as Level 2. The level of a value determined for an investment within
the fair value hierarchy is based upon the pricing transparency of the
investment and does not necessarily correspond to the LifePath Portfolios'
perceived risk of an investment in their corresponding Master Portfolio, nor the
levels of the investments held within the Master Portfolios.

The LifePath Portfolios believe more relevant disclosure regarding fair value
measurements relate to the investment portfolios of the Master Portfolios, which
can be found in the MIP's Pro Forma Notes to Combining Financial Statements, and
are included elsewhere in this report.

The performance of each LifePath Portfolio is directly affected by the
performance of its corresponding Master Portfolio. The financial statements of
each Master Portfolio, including the

                                       16




Schedule of Investments, are included elsewhere in this report and should be
read in conjunction with the corresponding LifePath Portfolio's financial
statements.

4) Capital Shares

The unaudited pro forma net asset value per share assumes retirement of the
LifePath 2010 Portfolio shares of common stock in connection with the proposed
acquisition of the LifePath 2010 Portfolio by the LifePath Retirement Portfolio
as of June 30, 2009. The number of retired shares was calculated by dividing the
net asset value of each class of the LifePath 2010 Portfolio by the respective
class net asset value per share of the LifePath Retirement Portfolio.

                     Shares of      Additional Shares   Total Outstanding
                   Acquiring Fund   Assumed Issued In         Shares
Class of Shares   Pre-Combination     The Agreement      Post-Combination
- ---------------   ---------------   -----------------   -----------------
Class I              11,158,953         27,988,486         39,147,439
Class R               2,914,706          9,781,589         12,696,295
Class S                   3,731              7,944             11,675

5) Unaudited Pro Forma Adjustments

The unaudited pro forma financial statements reflect changes in fund shares as
if the Agreement had taken place on June 30, 2009. LifePath 2010 Portfolio
expenses were adjusted assuming LifePath Retirement Portfolio's fee structure
was in effect for the twelve months ended June 30, 2009.

6) Use of Estimates

The following significant accounting policies are consistently followed by the
Trust in the preparation of its financial statements in conformity with U.S.
GAAP. The preparation of financial statements in conformity with U.S. GAAP
requires management to make certain estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosures of contingent assets
and liabilities at the date of the financial statements and the reported amounts
of revenue and expenses during the twelve months ended June 30, 2009. Actual
results could differ from those estimates.

7) Federal Income Taxes

Each LifePath Portfolio is treated as a separate entity for federal income tax
purposes. It is the policy of each LifePath Portfolio to qualify as a regulated
investment company by complying with the provisions applicable to regulated
investment companies, as defined under Subchapter M of the Internal Revenue Code
of 1986, as amended, and to annually distribute substantially all of its
ordinary income and any net capital gains (taking into account any capital loss
carryforwards) sufficient to relieve it from all, or substantially all, federal
income and excise

                                       17




taxes. Accordingly, no provision for federal income taxes was required for the
twelve months ended June 30, 2009.

The LifePath Portfolios had tax basis net capital carryforwards as of December
31, 2008, the tax year-end of the LifePath Portfolios, as follows:

                      Expiring
Portfolio               2016
- -------------------   --------
LifePath Retirement   $880,743
LifePath 2010               19

Net capital loss carryforwards may be applied against any net realized taxable
gains in each succeeding year or until their respective expiration dates,
whichever occurs first.

Management has reviewed the tax positions as of June 30, 2009, inclusive of the
prior three open tax return years, and has determined that no provision for
income tax is required in the LifePath Portfolios' financial statements.
