ITEM 1. REPORTS TO STOCKHOLDERS.

                               THE RBB FUND, INC.

This report is submitted for the general  information of the shareholders of the
Portfolio.  It is not authorized for distribution unless preceded or accompanied
by a prospectus for the Fund.
================================================================================




                               THE RBB FUND, INC.
                             MONEY MARKET PORTFOLIO
                             FUND EXPENSE EXAMPLES
                                  (UNAUDITED)

As a  shareholder  of the Fund,  you incur two types of costs:  (1)  transaction
costs and (2) ongoing costs,  including management fees,  distribution fees, and
other Fund expenses.  These  examples are intended to help you  understand  your
ongoing  costs (in dollars) of investing in the Fund and to compare  these costs
with the ongoing costs of investing in other mutual funds.

These examples are based on an investment of $1,000 invested at the beginning of
the period and held for the period from  September 1, 2005 through  February 28,
2006.

ACTUAL EXPENSES

The first line of the  accompanying  tables  provides  information  about actual
account values and actual  expenses.  You may use the  information in this line,
together  with the amount you  invested,  to estimate the expenses that you paid
over the period.  Simply divide your account  value by $1,000 (for  example,  an
$8,600  account value divided by $1,000 = 8.6),  then multiply the result by the
number in the first  line  under the  heading  entitled  "Expenses  Paid  During
Period" to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The  second  line  of  the  accompanying   tables  provides   information  about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense  ratio and an  assumed  rate of return of 5% per year  before  expenses,
which is not the Fund's  actual  return.  The  hypothetical  account  values and
expenses  may not be used to  estimate  the  actual  ending  account  balance or
expenses you paid for the period.  You may use this  information  to compare the
ongoing costs of investing in the Fund and other funds.  To do so, compare these
5% hypothetical  examples with the 5%  hypothetical  examples that appear in the
shareholder reports of other funds.

Please  note that the  expenses  shown in the  accompanying  tables are meant to
highlight  your ongoing costs only and do not reflect any  transactional  costs,
such as  redemption  fees that may be incurred by  shareholders  of other Funds.
Therefore,  the second line of the  accompanying  tables is useful in  comparing
ongoing costs only,  and will not help you determine the relative total costs of
owning different funds.

* Expenses  are equal to the Fund's  annualized  expense  ratio of 0.86% for the
  Bedford  Class  shares and 0.20% for the Sansom  Street  Class  shares,  which
  includes waived fees or reimbursed expenses, multiplied by the average account
  value  over the  period,  multiplied  by the  number of days (181) in the most
  recent  fiscal  half-year,  then divided by 365 to reflect the  one-half  year
  period.  The Fund's  ending  account  value on the first line in each table is
  based on the actual total return for each class of 1.65% for the Bedford Class
  shares and 1.98% for the Sansom Street Class shares.

                               THE RBB FUND, INC.
                             MONEY MARKET PORTFOLIO
                         NOTES TO FINANCIAL STATEMENTS
                               FEBRUARY 28, 2006
                                   (UNAUDITED)

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The RBB Fund, Inc. ("RBB" or "Company") was incorporated  under the laws of
the  State of  Maryland  on  February  29,  1988,  and is  registered  under the
Investment  Company  Act of 1940,  as  amended,  (the "1940 Act") as an open-end
management  investment  company.  RBB is a "series fund," which is a mutual fund
divided into separate portfolios. Each portfolio is treated as a separate entity
for  certain  matters  under  the  1940  Act,  and  for  other  purposes,  and a
shareholder  of one  portfolio  is not deemed to be a  shareholder  of any other
portfolio. Currently, RBB has seventeen active investment portfolios,  including
the Money  Market  Portfolio  ("Portfolio"),  which  comprise  the RBB family of
funds.

     RBB has  authorized  capital of thirty  billion  shares of common  stock of
which 26.473 billion shares are currently  classified into one hundred and three
classes of Common  Stock.  The  Portfolio  has issued shares with a par value of
$0.001.  Each  class  represents  an  interest  in an  active  or  inactive  RBB
investment  portfolio.  The active classes have been grouped into seven separate
"families," six of which have begun investment operations.

              A) SECURITY  VALUATION --  Securities  held in the  Portfolio  are
     valued under the amortized cost method,  which approximates  current market
     value. Under this method,  securities are valued at cost when purchased and
     thereafter  assumes  constant  accretion  of  discount or  amortization  of
     premium is recorded  until  maturity of the  security.  Regular  review and
     monitoring of the  valuation is performed to ensure that cost  continues to
     approximate  market value and to avoid  dilution or other unfair results to
     shareholders.  The Portfolio seeks to maintain net asset value per share at
     $1.00.

              B)  SECURITY  TRANSACTIONS,  INVESTMENT  INCOME,  AND  EXPENSES --
     Security  transactions  are  accounted  for on the trade date.  The cost of
     investments sold is determined by use of the specific identification method
     for both financial  reporting and income tax purposes.  Interest  income is
     accrued when  earned.  Certain  expenses,  such as  distribution,  transfer
     agency  and  printing,  are  class  specific  expenses  and vary by  class.
     Expenses not  directly  attributable  to a specific  portfolio or class are
     allocated  based on  relative  net  assets  of each  portfolio  and  class,
     respectively. Expenses incurred on behalf of a specific class, fund or fund
     family  are  charged  directly  to the  class,  fund  or  fund  family  (in
     proportion to net assets).  Expenses incurred for all portfolios within the
     RBB family of funds (such as director or professional  fees) are charged to
     all portfolios in proportion to their average net assets.

              C) DIVIDENDS AND  DISTRIBUTIONS  TO SHAREHOLDERS -- Dividends from
     net investment income are declared daily,  recorded on the ex-date and paid
     monthly. All distributions from net investment income are taxed as ordinary
     income.  Any net realized  capital gains are distributed at least annually.
     Income subject to  distributions  and capital gain subject to distributions
     are determined in accordance with income tax regulations,  which may differ
     from  accounting  principles  generally  accepted  in the United  States of
     America.

              D) FEDERAL INCOME TAXES -- No provision is made for federal income
     taxes.  It is the Company's  intention to have each  portfolio  continue to
     qualify for and elect the tax treatment  applicable to regulated investment
     companies   under  the  Internal   Revenue  Code  and  make  the  requisite
     distributions  to its  shareholders  which will be sufficient to relieve it
     from Federal income and excise taxes.

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

              E)  REPURCHASE  AGREEMENTS  --  Money  market  instruments  may be
     purchased subject to the seller's agreement to repurchase them at an agreed
     upon date and  price.  The  seller  will be  required  on a daily  basis to
     maintain the value of the  securities  subject to the agreement at not less
     than the  repurchase  price  plus  accrued  interest.  If the  value of the
     underlying securities falls below 102% of the value of the repurchase price
     plus accrued  interest,  the  Portfolio  will require the seller to deposit
     additional collateral by the next Portfolio business day. In the event that
     the seller under the  agreement  defaults on its  repurchase  obligation or
     fails to deposit sufficient  collateral,  the Portfolio has the contractual
     right, subject to the requirements of applicable  bankruptcy and insolvency
     laws, to sell the  underlying  securities  and may claim any resulting loss
     from the seller.  The agreements are conditioned  upon the collateral being
     deposited  under  the  Federal  Reserve  Book  Entry  System  or  with  the
     Portfolio's custodian or a third party sub-custodian.

              F) USE OF ESTIMATES -- The preparation of financial  statements in
     conformity  with  accounting  principles  generally  accepted in the United
     States of America  requires  management to make estimates and  assumptions.
     These estimates and assumptions  affect the reported  amounts of assets and
     liabilities and disclosure of contingent assets and liabilities at the date
     of the  financial  statements  and the  reported  amounts of  revenues  and
     expenses  during the  reporting  period.  Actual  results could differ from
     those estimates.

              G) OTHER -- In the normal  course of business,  the Fund may enter
     into contracts that provide  general  indemnifications.  The Fund's maximum
     exposure under these  arrangements  is dependent on claims that may be made
     against  the Fund in the  future,  and,  therefore,  cannot  be  estimated;
     however, based on experience,  the risk of material loss for such claims is
     considered remote.

NOTE 2. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

     Pursuant  to  Investment  Advisory  Agreements,   BlackRock   Institutional
Management  Corp.  (the  "Adviser"  or  "BIMC"),   an  indirect   majority-owned
subsidiary  of The PNC  Financial  Services  Group,  Inc.,  serves as investment
adviser and as administrator for the Portfolio. BIMC and PFPC Inc. ("PFPC") have
entered into a delegation agreement on behalf of the Portfolio, wherein PFPC has
agreed to perform  administration  and accounting  services for an annual fee of
0.10% of the  average net assets of the  Portfolio,  paid out of the fee paid to

account values and actual  expenses.  You may use the  information in this line,
together  with the amount you  invested,  to estimate the expenses that you paid
over the period.  Simply divide your account  value by $1,000 (for  example,  an
$8,600  account value divided by $1,000 = 8.6),  then multiply the result by the
number in the first  line  under the  heading  entitled  "Expenses  Paid  During
Period" to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The  second  line  of  the  accompanying   tables  provides   information  about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense  ratio and an  assumed  rate of return of 5% per year  before  expenses,
which is not the Fund's  actual  return.  The  hypothetical  account  values and
expenses  may not be used to  estimate  the  actual  ending  account  balance or
expenses you paid for the period.  You may use this  information  to compare the
ongoing costs of investing in the Fund and other funds.  To do so, compare these
5% hypothetical  examples with the 5%  hypothetical  examples that appear in the
shareholder reports of other funds.

Please  note that the  expenses  shown in the  accompanying  tables are meant to
highlight  your ongoing costs only and do not reflect any  transactional  costs,
such as  redemption  fees that may be incurred by  shareholders  of other Funds.
Therefore,  the second line of the  accompanying  tables is useful in  comparing
ongoing costs only,  and will not help you determine the relative total costs of
owning different funds.

*  Expenses are equal to the Fund's annualized expense ratio of 0.86% for the Bedford Class shares and
   0.20% for the Sansom  Street Class  shares,  which  includes  waived fees or  reimbursed  expenses,
   multiplied by the average account value over the period,  multiplied by the number of days (181) in
   the most recent  fiscal  half-year,  then divided by 365 to reflect the one-half  year period.  The
   Fund's ending account value on the first line in each table is based on the actual total return for
   each class of 1.65% for the Bedford Class shares and 1.98% for the Sansom Street Class shares.

                               THE RBB FUND, INC.
                             MONEY MARKET PORTFOLIO
                          NOTES TO FINANCIAL STATEMENTS
                                FEBRUARY 28, 2006
                                   (UNAUDITED)

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   The RBB Fund,  Inc. ("RBB" or "Company") was  incorporated  under the laws of
the  State of  Maryland  on  February  29,  1988,  and is  registered  under the
Investment  Company  Act of 1940,  as  amended,  (the "1940 Act") as an open-end
management  investment  company.  RBB is a "series fund," which is a mutual fund
divided into separate portfolios. Each portfolio is treated as a separate entity
for  certain  matters  under  the  1940  Act,  and  for  other  purposes,  and a
shareholder  of one  portfolio  is not deemed to be a  shareholder  of any other
portfolio. Currently, RBB has seventeen active investment portfolios,  including
the Money  Market  Portfolio  ("Portfolio"),  which  comprise  the RBB family of
funds.

   RBB has authorized  capital of thirty billion shares of common stock of which
26.473  billion  shares are  currently  classified  into one  hundred  and three
classes of Common  Stock.  The  Portfolio  has issued shares with a par value of
$0.001.  Each  class  represents  an  interest  in an  active  or  inactive  RBB
investment  portfolio.  The active classes have been grouped into seven separate
"families," six of which have begun investment operations.

       A) SECURITY  VALUATION --  Securities  held in the  Portfolio  are valued
   under the amortized  cost method,  which  approximates  current market value.
   Under  this  method,  securities  are  valued  at  cost  when  purchased  and
   thereafter  assumes constant accretion of discount or amortization of premium
   is recorded until maturity of the security.  Regular review and monitoring of
   the  valuation  is performed  to ensure that cost  continues  to  approximate
   market value and to avoid dilution or other unfair  results to  shareholders.
   The Portfolio seeks to maintain net asset value per share at $1.00.

       B) SECURITY  TRANSACTIONS,  INVESTMENT  INCOME,  AND EXPENSES -- Security
   transactions  are  accounted for on the trade date.  The cost of  investments
   sold is  determined  by use of the  specific  identification  method for both
   financial reporting and income tax purposes.  Interest income is accrued when
   earned. Certain expenses, such as distribution, transfer agency and printing,
   are  class  specific  expenses  and  vary by  class.  Expenses  not  directly
   attributable to a specific portfolio or class are allocated based on relative
   net assets of each portfolio and class,  respectively.  Expenses  incurred on
   behalf of a specific class,  fund or fund family are charged  directly to the
   class,  fund or fund family (in proportion to net assets).  Expenses incurred
   for all  portfolios  within  the RBB  family of funds  (such as  director  or
   professional  fees) are  charged to all  portfolios  in  proportion  to their
   average net assets.

       C) DIVIDENDS AND  DISTRIBUTIONS  TO  SHAREHOLDERS  -- Dividends  from net
   investment  income are  declared  daily,  recorded  on the  ex-date  and paid
   monthly.  All distributions  from net investment income are taxed as ordinary
   income.  Any net realized  capital gains are  distributed at least  annually.
   Income subject to distributions and capital gain subject to distributions are
   determined in accordance with income tax  regulations,  which may differ from
   accounting principles generally accepted in the United States of America.

       D) FEDERAL INCOME TAXES -- No provision is made for federal income taxes.
   It is the Company's  intention to have each portfolio continue to qualify for
   and elect the tax  treatment  applicable  to regulated  investment  companies
   under the Internal  Revenue Code and make the requisite  distributions to its
   shareholders  which will be sufficient to relieve it from Federal  income and
   excise taxes.

                                   (UNAUDITED)

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

       E)  REPURCHASE  AGREEMENTS -- Money market  instruments  may be purchased
   subject to the seller's  agreement to repurchase  them at an agreed upon date
   and price. The seller will be required on a daily basis to maintain the value
   of the  securities  subject to the agreement at not less than the  repurchase
   price plus accrued interest.  If the value of the underlying securities falls
   below 102% of the value of the repurchase  price plus accrued  interest,  the
   Portfolio  will require the seller to deposit  additional  collateral  by the
   next Portfolio business day. In the event that the seller under the agreement
   defaults  on  its  repurchase  obligation  or  fails  to  deposit  sufficient
   collateral,   the  Portfolio  has  the  contractual  right,  subject  to  the
   requirements  of  applicable  bankruptcy  and  insolvency  laws,  to sell the
   underlying  securities and may claim any resulting loss from the seller.  The
   agreements are  conditioned  upon the collateral  being  deposited  under the
   Federal  Reserve  Book Entry  System or with the  Portfolio's  custodian or a
   third party sub-custodian.

       F) USE OF  ESTIMATES  --  The  preparation  of  financial  statements  in
   conformity with accounting principles generally accepted in the United States
   of America  requires  management  to make  estimates and  assumptions.  These
   estimates  and  assumptions   affect  the  reported  amounts  of  assets  and
   liabilities  and disclosure of contingent  assets and liabilities at the date
   of the financial statements and the reported amounts of revenues and expenses
   during  the  reporting  period.   Actual  results  could  differ  from  those
   estimates.

       G) OTHER -- In the  normal  course of  business,  the Fund may enter into
   contracts that provide general indemnifications.  The Fund's maximum exposure
   under these  arrangements is dependent on claims that may be made against the
   Fund in the future, and, therefore,  cannot be estimated;  however,  based on
   experience, the risk of material loss for such claims is considered remote.

NOTE 2. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

   Pursuant  to  Investment   Advisory   Agreements,   BlackRock   Institutional
Management  Corp.  (the  "Adviser"  or  "BIMC"),   an  indirect   majority-owned
subsidiary  of The PNC  Financial  Services  Group,  Inc.,  serves as investment
adviser and as administrator for the Portfolio. BIMC and PFPC Inc. ("PFPC") have
entered into a delegation agreement on behalf of the Portfolio, wherein PFPC has
agreed to perform  administration  and accounting  services for an annual fee of
0.10% of the  average net assets of the  Portfolio,  paid out of the fee paid to
BIMC.

   For its advisory  services,  BIMC is entitled to receive the following  fees,
computed daily and payable monthly,  and based on the Portfolio's  average daily
net assets:

           PORTFOLIO                             ANNUAL RATE

NOTE 2. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES (CONTINUED)

   BIMC may,  at its  discretion,  voluntarily  waive all or any  portion of its
advisory fee for the  Portfolio.  For each class of shares within the Portfolio,

   Money Market Portfolio            $535,243       $(460,547)      $74,696

   As of February 28, 2006, the Portfolio owed BIMC $11,485 in advisory fees.

   The investment adviser/administrator may voluntarily waive and/or reimburse a
portion  of its  management  fees.  The  portfolio  service  provider  may  also
voluntarily waive a portion of their fees and/or reimburse expenses.

   The Funds will not pay BIMC at a later  time for any  amounts it may waive or
any amounts that BIMC has assumed.

   For providing regulatory  administration services to RBB, PFPC is entitled to
receive compensation as agreed to by the Company and PFPC. This fee is allocated
to each  portfolio  in  proportion  to their net  assets of the RBB  funds.  The
Portfolio's  portion of this fee for the six months ended  February 28, 2006 was
$15,434.

   PFPC serves as the  transfer and  dividend  disbursing  agent for each class.
Both PFPC Trust Co. and PFPC are  wholly-owned  subsidiaries  of PFPC  Worldwide
Inc., an indirect  wholly-owned  subsidiary of The PNC Financial Services Group,

 This report is submitted for the general information of the shareholders of the
 Portfolio. It is not authorized for distribution unless preceded or accompanied
 by a prospectus for the Fund.

================================================================================



                               THE RBB FUND, INC.
                             MONEY MARKET PORTFOLIO
                             FUND EXPENSE EXAMPLES
                                  (UNAUDITED)

As a  shareholder  of the Fund,  you incur two types of costs:  (1)  transaction
costs and (2) ongoing costs,  including management fees,  distribution fees, and
other Fund expenses.  These  examples are intended to help you  understand  your
ongoing  costs (in dollars) of investing in the Fund and to compare  these costs
with the ongoing costs of investing in other mutual funds.

These examples are based on an investment of $1,000 invested at the beginning of
the period and held for the period from  September 1, 2005 through  February 28,
2006.

ACTUAL EXPENSES

The first line of the  accompanying  tables  provides  information  about actual
account values and actual  expenses.  You may use the  information in this line,
together  with the amount you  invested,  to estimate the expenses that you paid
over the period.  Simply divide your account  value by $1,000 (for  example,  an
$8,600  account value divided by $1,000 = 8.6),  then multiply the result by the
number in the first  line  under the  heading  entitled  "Expenses  Paid  During
Period" to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The  second  line  of  the  accompanying   tables  provides   information  about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense  ratio and an  assumed  rate of return of 5% per year  before  expenses,
which is not the Fund's  actual  return.  The  hypothetical  account  values and
expenses  may not be used to  estimate  the  actual  ending  account  balance or
expenses you paid for the period.  You may use this  information  to compare the
ongoing costs of investing in the Fund and other funds.  To do so, compare these
5% hypothetical  examples with the 5%  hypothetical  examples that appear in the
shareholder reports of other funds.

Please  note that the  expenses  shown in the  accompanying  tables are meant to
highlight  your ongoing costs only and do not reflect any  transactional  costs,
such as  redemption  fees that may be incurred by  shareholders  of other Funds.
Therefore,  the second line of the  accompanying  tables is useful in  comparing
ongoing costs only,  and will not help you determine the relative total costs of
owning different funds.

  half-year,  then divided by 365 to reflect the one-half year period.  The Fund's ending account value on the

  shares and 1.98% for the Sansom Street Class shares.

                               THE RBB FUND, INC.
                             MONEY MARKET PORTFOLIO
                          NOTES TO FINANCIAL STATEMENTS
                                FEBRUARY 28, 2006
                                   (UNAUDITED)

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      The RBB Fund, Inc. ("RBB" or "Company") was incorporated under the laws of
the  State of  Maryland  on  February  29,  1988,  and is  registered  under the
Investment  Company  Act of 1940,  as  amended,  (the "1940 Act") as an open-end
management  investment  company.  RBB is a "series fund," which is a mutual fund
divided into separate portfolios. Each portfolio is treated as a separate entity
for  certain  matters  under  the  1940  Act,  and  for  other  purposes,  and a
shareholder  of one  portfolio  is not deemed to be a  shareholder  of any other
portfolio. Currently, RBB has seventeen active investment portfolios,  including
the Money  Market  Portfolio  ("Portfolio"),  which  comprise  the RBB family of
funds.

      RBB has  authorized  capital of thirty  billion  shares of common stock of
which 26.473 billion shares are currently  classified into one hundred and three
classes of Common  Stock.  The  Portfolio  has issued shares with a par value of
$0.001.  Each  class  represents  an  interest  in an  active  or  inactive  RBB
investment  portfolio.  The active classes have been grouped into seven separate
"families," six of which have begun investment operations.

            A) SECURITY VALUATION -- Securities held in the Portfolio are valued
      under the amortized cost method,  which approximates current market value.
      Under  this  method,  securities  are  valued at cost when  purchased  and
      thereafter  assumes  constant  accretion  of discount or  amortization  of
      premium is recorded  until  maturity of the security.  Regular  review and
      monitoring of the valuation is performed to ensure that cost  continues to
      approximate  market value and to avoid dilution or other unfair results to
      shareholders. The Portfolio seeks to maintain net asset value per share at
      $1.00.

            B)  SECURITY  TRANSACTIONS,   INVESTMENT  INCOME,  AND  EXPENSES  --
      Security  transactions  are accounted  for on the trade date.  The cost of
      investments  sold  is  determined  by use of the  specific  identification
      method for both  financial  reporting  and income tax  purposes.  Interest
      income is accrued when earned.  Certain  expenses,  such as  distribution,
      transfer  agency and  printing,  are class  specific  expenses and vary by
      class. Expenses not directly attributable to a specific portfolio or class
      are  allocated  based on relative net assets of each  portfolio and class,
      respectively.  Expenses  incurred on behalf of a specific  class,  fund or
      fund  family are charged  directly  to the class,  fund or fund family (in
      proportion to net assets). Expenses incurred for all portfolios within the
      RBB family of funds (such as director or professional fees) are charged to
      all portfolios in proportion to their average net assets.

            C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net
      investment  income are  declared  daily,  recorded on the ex-date and paid
      monthly.  All  distributions  from  net  investment  income  are  taxed as
      ordinary  income.  Any net realized capital gains are distributed at least
      annually.  Income  subject to  distributions  and capital  gain subject to
      distributions  are determined in accordance  with income tax  regulations,
      which may differ  from  accounting  principles  generally  accepted in the
      United States of America.

            D) FEDERAL  INCOME TAXES -- No provision is made for federal  income
      taxes.  It is the Company's  intention to have each portfolio  continue to
      qualify for and elect the tax treatment applicable to regulated investment
      companies  under  the  Internal   Revenue  Code  and  make  the  requisite
      distributions to its  shareholders  which will be sufficient to relieve it
      from Federal income and excise taxes.

                               THE RBB FUND, INC.

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                FEBRUARY 28, 2006
                                   (UNAUDITED)

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

            E)  REPURCHASE   AGREEMENTS  --  Money  market  instruments  may  be
      purchased  subject to the  seller's  agreement  to  repurchase  them at an
      agreed  upon date and price.  The seller will be required on a daily basis
      to maintain the value of the  securities  subject to the  agreement at not
      less than the repurchase price plus accrued interest.  If the value of the
      underlying  securities  falls  below  102% of the value of the  repurchase
      price plus  accrued  interest,  the  Portfolio  will require the seller to
      deposit  additional  collateral by the next Portfolio business day. In the
      event that the  seller  under the  agreement  defaults  on its  repurchase
      obligation or fails to deposit  sufficient  collateral,  the Portfolio has
      the  contractual   right,   subject  to  the  requirements  of  applicable
      bankruptcy and insolvency laws, to sell the underlying  securities and may
      claim any resulting loss from the seller.  The agreements are  conditioned
      upon the collateral  being  deposited under the Federal Reserve Book Entry
      System or with the Portfolio's custodian or a third party sub-custodian.

            F) USE OF ESTIMATES -- The  preparation  of financial  statements in
      conformity with  accounting  principles  generally  accepted in the United
      States of America  requires  management to make estimates and assumptions.
      These estimates and assumptions  affect the reported amounts of assets and
      liabilities  and  disclosure of contingent  assets and  liabilities at the
      date of the financial  statements and the reported amounts of revenues and
      expenses  during the reporting  period.  Actual  results could differ from
      those estimates.

            G) OTHER -- In the  normal  course of  business,  the Fund may enter
      into contracts that provide general  indemnifications.  The Fund's maximum
      exposure under these  arrangements is dependent on claims that may be made
      against  the Fund in the  future,  and,  therefore,  cannot be  estimated;
      however, based on experience, the risk of material loss for such claims is
      considered remote.

NOTE 2. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

            Pursuant to Investment Advisory Agreements,  BlackRock Institutional
      Management  Corp.  (the "Adviser" or "BIMC"),  an indirect  majority-owned
      subsidiary of The PNC Financial Services Group, Inc., serves as investment
      adviser  and as  administrator  for the  Portfolio.  BIMC  and  PFPC  Inc.
      ("PFPC")  have  entered  into a  delegation  agreement  on  behalf  of the
      Portfolio,   wherein  PFPC  has  agreed  to  perform   administration  and
      accounting  services  for an annual fee of 0.10% of the average net assets
      of the Portfolio, paid out of the fee paid to BIMC.

NOTE 2. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES (CONTINUED)

            BIMC may, at its discretion, voluntarily waive all or any portion of
      its advisory fee for the  Portfolio.  For each class of shares  within the
      Portfolio,  the net  advisory  fee  charged to each class is the same on a
      relative basis. For the six months ended February 28, 2006,  advisory fees

      As of February 28, 2006, the Portfolio owed BIMC $11,485 in advisory fees.

      The  investment   adviser/administrator   may  voluntarily   waive  and/or
reimburse a portion of its management  fees. The portfolio  service provider may
also voluntarily waive a portion of their fees and/or reimburse expenses.

      The Funds will not pay BIMC at a later  time for any  amounts it may waive
or any amounts that BIMC has assumed.

      For providing regulatory  administration services to RBB, PFPC is entitled
to  receive  compensation  as agreed  to by the  Company  and PFPC.  This fee is
allocated to each  portfolio in proportion to their net assets of the RBB funds.

                                       1


The N/I  NUMERIC  INVESTORS  FAMILY OF FUNDS  experienced  significant  positive
returns during the six-month  period ended February 28, 2006,  with the smallest
return being 9.2%. In three of the four funds, the significant positive absolute
return was  augmented  by a positive  benchmark-relative  return.  The  positive
benchmark-relative  return  during the period  ranged from slightly more than 1%
for the Small Cap Value Fund to 2.9% for the Mid Cap Fund,  with only the Growth
Fund trailing its benchmark by about 2%.

Equity markets were once again firm over the six-month period ended February 28,
2006,  more  than  recovering  from a sharp  pull-back  during  October,  with a
majority  of the  positive  return  coming  during  the months of  November  and
January.  October's  decline  was  precipitated  by  lack-luster  third  quarter
earnings relative to aggressive  expectations,  combined with some soft economic
data (e.g. weaker than expected measures for: a leading economic index, consumer
confidence,  industrial  production,  and durable  goods  orders).  In addition,
inflationary  concerns  also  weighed  on the  market  following  a higher  than
expected  producer price index.  Equity markets then spent the month of November
more than undoing October's  decline.  Most of the economic data released during
the month  (including  consumer  confidence,  durable  goods  orders and leading
economic  indicators)   re-established   investor  confidence  that  the  growth
trajectory  remains intact and that  inflation is being kept in check.  Finally,
January  was the most  fruitful  month for equity  investors  during this recent
semi-annual  period,  as the Russell  3000(R) was up over 3.3%.  Generally  tame
inflation  measures  during the month  prompted many to believe that the Federal
Reserve  may be at the end of its  tightening  cycle.  Furthermore,  January was
marked  by  an   increased   appetite   for  risk  by   investors,   as  smaller
capitalization, higher beta, and high growth stocks all outperformed.

The Federal Reserve continued its "measured pace policy" of monetary  tightening
and raised the federal funds target rate four times, in each instance by 25 bps,
over this six month period.  This Fed  tightening  has brought the federal funds
rate from 3.5% to 4.5%. More importantly, the rate increases at the short end of
the yield curve (i.e.  the portion which the Federal  Reserve has direct control
over) have been met with stubbornly  resilient  yields at the long end (i.e. the
portion, such as the 10-year bond, which is controlled by market forces). During
our last letter at the end of August 2005, we indicated that the yield curve may
become inverted by year end.  Indeed,  it has become  inverted,  with the spread
between 2-year T-Bills and 10-year Treasuries  standing down 12bps at the end of
this semi-annual period.

Inspecting  the  market's  return in greater  detail  during the past six months
reveals that  investors  once again  demonstrated  a  preference  for smaller to
mid-sized companies over their large cap counterparts. In addition, a preference
was  shown for  value  stocks  over  growth  stocks in the large  capitalization
domain,  while the reverse  was true in the mid and small cap domain.  Using the
Russell  style  indices,  small  cap  growth  stocks  were  found to be the best
performing  group during the period,  with the Russell  2000(R)  Growth index up
11.69%.

As you  will  recall,  we  construct  our  portfolios  using a  bottom-up  stock
selection process that is based on our proprietary quantitative  stock-selection
models. These models allow us to formulate a view on the fair price for a stock,
considering its growth and stability,  and take into account analysts'  estimate
revisions,  and the quality of a company's earnings.  In addition,  while always
seeking to have strong  absolute  performance,  we are primarily  focused on the
benchmark-relative  return of each Fund.  For this  reason,  we seek to mitigate
unnecessary  risks by managing  portfolios that are effectively  economic-sector
neutral  with respect to their  benchmark.  Namely,  we seek to maintain  sector
weights  that  are only a few  percentage  points  away  from  their  respective
benchmark sector weights. Furthermore, we try to avoid large stock-specific risk
by broadly  diversifying  the portfolio across many stocks and by preventing any
one holding from exceeding approximately 2% of a Fund's overall weight.


                                       2


An  attribution  analysis of each Fund's return over the past six months reveals
that our  information-flow  based models (i.e. Estrend,  Quality of Earnings and
Short  Interest)  all  added  value  across  the Fund  family.  This is in sharp
contrast to our Fair Value model which suffered another period of weakness.  The
alternative  valuation  technique based on cash flow and used for growth stocks,
did not mitigate these losses but rather also contributed. While the information
flow success was  sufficient to overcome  Fair Value's  weakness in the Mid Cap,
Emerging Growth,  and Small Cap Value Funds, this was unfortunately not true for
the  Growth  Fund.  The end  result was that the  former  three  funds  achieved
positive  benchmark-relative  returns over this semi-annual period, while Growth
did not. As we  mentioned  in our last letter,  the Fair Value  weakness,  while
undesirable, follows a fruitful period of several years. The return to value has
been substantial  post the equity bubble  bursting,  leading to a compression in
valuation  disparities  across the market. It is not altogether  surprising that
the Fair Value model may suffer some decline for short  periods  following  such
success  and  resulting  compression.  However,  we believe  that the growth and
quality  adjustments  made in our Fair  Value  model,  combined  with our use of
information flow, will ultimately help the strategies add value.

The following  table  summarizes  which economic  sectors were among the largest
positive  contributors to the benchmark relative return for each Fund during the
six-month period ended February 28, 2006.

      FUND               LARGEST CONTRIBUTING SECTORS            SECTOR'S RETURN

Mid Cap                     Consumer Non-Cyclicals                    15.0%
                              Consumer Cyclicals                       9.9%
Small Cap Value               Consumer Cyclicals                      11.8%
                                  Industrials                         19.7%

Examining the benchmark relative return at the individual security level for the
Emerging Growth Fund, the construction machinery  manufacturer,  JLG Industries,
(+50bps  contribution  to the Fund's relative  return),  and the printed circuit
board manufacturer,  Multi-Fineline  Electronix (+49bps), were among the largest
positive  contributors  to the  Fund's  benchmark  relative  return  during  the
six-month  period.  The  largest  detractors  included  Tekelec  (-23bps),   the
telecommunications equipment manufacturer, and Transmontaigne Inc. (-22bps), the
oilfield services company.

The Growth Fund's largest positive  contributors to relative return included the
specialty  investment  services  company,  GFI  Group  (+50bps),  and the  heavy
machinery  manufacturer,  Terex  Corp.  (+33bps).  On the  downside,  Nash Finch
(-23bps),  the food wholesaler,  and The Mills Corp.  (-23bps),  a regional mall
real-estate  investment trust company,  were among the largest detractors to the
relative return.

Considering  the Mid Cap Fund, the largest  contributors  to the relative return
included the hard disk drive manufacturer,  Seagate Technology (+55bps), and the
pharmacy benefit management company,  Express Scripts (+48bps).  The Mills Corp.
(-34bps), a regional mall real-estate investment trust company, and IPC Holdings
(-29bps), the property catastrophe re-insurer, were among the largest detractors
from the Fund's relative return.


                                       3


Finally,  for the Small Cap Value Fund,  the largest  positive  contributors  to
relative   return   included  the  hotel   franchise   company,   Choice  Hotels
International  (+50bps),  and the  oil  refining  company,  Frontier  Oil  Corp.
(+40bps).  The holdings  which most  negatively  impacted  the  relative  return
included Nash Finch (-40bps),  the food wholesaler,  and IPC Holdings  (-33bps),
the property catastrophe re-insurer.

                              EMERGING GROWTH FUND
                                  GROWTH FUND
                                  MID CAP FUND
                              SMALL CAP VALUE FUND

                        FUND EXPENSE EXAMPLES (UNAUDITED)

As a shareholder of the Fund(s),  you incur two types of costs:  (1) transaction
costs,  including  redemption fees and (2) ongoing costs,  including  management
fees and other Fund expenses. These examples are intended to help you understand
your ongoing costs (in dollars) of investing in the Fund(s) and to compare these
costs with the ongoing costs of investing in other mutual funds.

These examples are based on an investment of $1,000 invested at the beginning of
the period and held for the period from  September 1, 2005 through  February 28,
2006.

ACTUAL EXPENSES

The first line of the  accompanying  tables  provides  information  about actual
account values and actual  expenses.  You may use the  information in this line,
together  with the amount you  invested,  to estimate  the expense that you paid
over the period.  Simply divide your account  value by $1,000 (for  example,  an
$8,600  account value divided by $1,000 = 8.6),  then multiply the result by the
number in the first  line  under the  heading  entitled  "Expenses  Paid  During
Period" to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The  second  line  of  the  accompanying   tables  provides   information  about
hypothetical  account  values and  hypothetical  expenses  based on your  Fund's
actual  expense  ratio  and an  assumed  rate of  return  of 5% per year  before
expenses, which is not the Fund's actual return. The hypothetical account values
and expenses may not be used to estimate the actual  ending  account  balance or
expenses you paid for the period.  You may use this  information  to compare the
ongoing costs of investing in the Fund and other funds.  To do so,  compare this
5%  hypothetical  example with the 5%  hypothetical  examples that appear in the
shareholder reports of other funds.

Please  note that the  expenses  shown in the  accompanying  tables are meant to
highlight  your ongoing costs only and do not reflect any  transactional  costs,
such as redemption fees.  Therefore,  the second line of the accompanying tables
is useful in comparing  ongoing costs only,  and will not help you determine the
relative  total  costs  of  owning  different  funds.  In  addition,   if  these
transactional costs were included, your costs would have been higher.

*     Amount is less than $0.01 per share.

(1)   Calculated based on average shares outstanding for the period.

(2)   The  amounts  shown  for a share  outstanding  throughout  the  respective
      periods  are not in accord  with the  changes in the  aggregate  gains and
      losses on investments  during the respective periods because of the timing
      of the sales and repurchases of fund shares in relation to fluctuating net
      asset values during the respective periods.

(3)   Total investment return is calculated assuming a purchase of shares on the
      first day and a sale of shares on the last day of each period reported and
      includes reinvestment of dividends and distributions, if any.

(4)   Reflects waivers and expense reimbursements, if any.

(5)   Annualized.

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

The RBB Fund, Inc. ("RBB" or "Company") was  incorporated  under the laws of the
State of Maryland on February 29, 1988,  and is registered  under the Investment
Company Act of 1940, as amended (the  "Investment  Company Act"), as an open-end
management  investment  company.  RBB is a "series fund," which is a mutual fund
divided into separate portfolios. Each portfolio is treated as a separate entity
for certain  matters under the Investment  Company Act, and for other  purposes,
and a  shareholder  of one  portfolio is not deemed to be a  shareholder  of any
other  portfolio.  Currently,  RBB has seventeen active  investment  portfolios,
including  the N/I NUMERIC  INVESTORS  FAMILY OF FUNDS ("n/i  numeric  investors
Family") which consists of four diversified  portfolios:  N/I NUMERIC  INVESTORS
Emerging Growth Fund ("Emerging Growth Fund"), N/I NUMERIC INVESTORS Growth Fund
("Growth  Fund"),  N/I NUMERIC  INVESTORS  Mid Cap Fund ("Mid Cap Fund") and N/I
NUMERIC INVESTORS Small Cap Value Fund ("Small Cap Value Fund") (each, a "Fund,"
and collectively, the "Funds").

RBB has  authorized  capital of thirty  billion  shares of common stock of which
26.473  billion are currently  classified  into one hundred and three classes of
common  stock.  Each class  represents  an interest in an active or inactive RBB
investment  portfolio.  The active classes have been grouped into seven separate
"families," six of which have begun investment operations.

USE OF ESTIMATES -- The  preparation of financial  statements in conformity with
accounting  principles  generally  accepted  in the  United  States of  America,
requires  management to make estimates and assumptions  that affect the reported
amounts  of assets and  liabilities  and  disclosure  of  contingent  assets and
liabilities at the date of the financial  statements and the reported amounts of
revenues and expenses during the period.  Actual results could differ from those
estimates.

PORTFOLIO  VALUATION -- The Funds' net asset value  ("NAV") is  calculated  once
daily at the close of regular  trading  hours on the NYSE  (generally  4:00 p.m.
Eastern  time) on each day the NYSE is open.  Securities  held by the  Funds are
valued using the closing  price or the last sale price on a national  securities
exchange  or  on  the  National  Association  of  Securities  Dealers  Automatic
Quotation System  ("NASDAQ")  market system where they are primarily  traded. If
there  were  no  sales  on  that  day or the  securities  are  traded  on  other
over-the-counter  markets,  the mean of the last bid and ask prices prior to the
market close are used. Short-term debt securities having a remaining maturity of
60 days or less are amortized to maturity based on their cost.  Debt  securities
having a  remaining  maturity  of  greater  than 60 days are  valued at the mean
between the bid and ask prices.  With the  approval  of the  Company's  Board of
Directors, the Funds may use a pricing service, bank or broker/dealer experience
in providing valuations to value the Funds' securities. If market quotations are
unavailable  or deemed  unreliable,  securities  will be  valued  by the  Funds'
Valuation Committee following procedures adopted by the Board of Directors.

REPURCHASE  AGREEMENTS  -- Each Fund has  agreed  to  purchase  securities  from
financial  institutions  subject to the seller's agreement to repurchase them at
an  agreed-upon  time  and  price  ("repurchase   agreements").   The  financial
institutions with whom each Fund enters into repurchase agreements are banks and
broker/dealers,   which  Numeric  Investors  LLC(R)  (the  Funds'  "Adviser"  or
"Numeric") considers creditworthy.  The seller under a repurchase agreement will
be required to maintain the value of the  securities as  collateral,  subject to
the agreement at not less than the repurchase price plus accrued interest.

                              SMALL CAP VALUE FUND

             NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

Numeric  marks to market daily the value of the  collateral,  and, if necessary,
requires the seller to deposit  additional  collateral by the next business day,
so that the  value of the  collateral  is not less  than the  repurchase  price.
Default by or  bankruptcy  of the seller  would,  however,  expose  each Fund to
possible loss because of adverse market action or delays in connection  with the
disposition of the underlying securities.

INVESTMENT  TRANSACTIONS,  INVESTMENT  INCOME AND  EXPENSES -- The Funds  record
security  transactions  on the  trade  date.  The  cost of  investments  sold is
determined  by use of the  specific  identification  method  for both  financial
reporting and income tax purposes in  determining  realized  gains and losses on
investments. Interest income is accrued when earned. Dividend income is recorded
on the ex-dividend date.  Distributions  received on securities that represent a
return of  capital  or  capital  gain are  recorded  as a  reduction  of cost of
investments  and/or as a realized  gain.  The Funds  estimate the  components of
distributions received that may be considered return of capital distributions or
capital gain  distributions.  Expenses  incurred on behalf of a specific fund or
fund family are charged  directly to the fund or fund family (in  proportion  to
net assets).  Expenses incurred for all of the RBB families (such as director or
professional fees) are charged to all funds in proportion to their net assets of
the RBB Funds,  or in such other manner as the Board of Directors  deems fair or
equitable.  Expenses and fees,  including investment advisory and administration
fees,  are accrued  daily and taken into account for the purpose of  determining
the net asset value of the Funds.

DIVIDENDS AND  DISTRIBUTIONS  TO  SHAREHOLDERS  -- Dividends from net investment
income and  distributions  from net  realized  capital  gains,  if any,  will be
declared  and  recorded on the  ex-dividend  date and paid at least  annually to
shareholders.  Income dividends and capital gain distributions are determined in
accordance  with U.S.  federal  income tax  regulations,  which may differ  from
accounting principles generally accepted in the United States of America.  These
differences can include the treatment of non-taxable dividends, expiring capital
loss carryforwards,  foreign currency gain/loss, and losses deferred due to wash
sales and  excise  tax  regulations.  Permanent  book and tax basis  differences
relating to shareholder  distributions will result in  reclassifications  within
the composition of net assets.

U.S.  TAX STATUS -- No  provision  is made for U.S.  income  taxes as it is each
Fund's  intention  to  continue  to  qualify  for and  elect  the tax  treatment
applicable to regulated  investment companies under Subchapter M of the Internal
Revenue Code of 1986, as amended,  and make the requisite  distributions  to its
shareholders  which will be sufficient  to relieve it from all or  substantially
all U.S. federal income and excise taxes.

OTHER -- In the normal  course of business,  the Funds may enter into  contracts
that provide general  indemnifications.  The Funds' maximum exposure under these
arrangements  is  dependent  on claims that may be made against the Funds in the
future, and, therefore,  cannot be estimated;  however, based on experience, the
risk of material loss for such claims is considered remote.

2. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

Numeric  serves as each  Fund's  investment  adviser.  Numeric is  entitled to a
performance  based fee for its  advisory  services  for the Growth,  Mid Cap and
Small Cap Value Funds  calculated  at the end of each month using a basic fee of
0.85% of average daily net assets and a performance  fee  adjustment  based upon
each Fund's performance during the last rolling 12-month period. Each Fund's net
performance is compared with the  performance of its benchmark index during that
same rolling  12-month  period.  When a Fund's  performance is between 4.00% and
4.99%  better than its  benchmark,  it would pay  Numeric the basic fee.  When a
Fund's  performance  is at least 5.00% better than its  benchmark,  it would pay
Numeric more than the basic fee. If a Fund did not perform at least 4.00% better
than its benchmark, Numeric would be paid less than the basic fee. Each 1.00% of
the difference in performance between a Fund and its benchmark plus 4.00% during
the performance  period would result in a 0.10% adjustment to the basic fee. The
benchmark  index for the Growth Fund is the Russell  2500(R)  Growth  Index.  On
November 12, 2004,  during a special  meeting,  shareholders of the Mid Cap Fund
approved a proposal to change the Fund's  benchmark  from the S&P MidCap  400(R)
Index to the  Russell  MidCap(R)  Index.  The  Adviser  elected  to  change  the
benchmark index because the Russell MidCap(R) Index more appropriately  reflects
the types of  securities  held in the Fund's  portfolio  and  provides  the best
comparative performance information.  From December 1, 2004 through November 30,
2005, the  performance  fee was compared to both the S&P MidCap 400(R) Index and
the  Russell  MidCap(R)  Index  separately  each month.  Each month  during this
period,  the Fund paid the advisory  fee based upon  whichever  performance  fee
calculation  resulted in a lower advisory fee.  Effective  December 1, 2005, the
Fund  began  paying  an  advisory  fee  based  solely  on  the  performance  fee
calculation of the Russell  MidCap(R)  Index.  The benchmark index for the Small
Cap Value Fund is the Russell 2000(R) Value Index.

The  maximum  annualized  performance  adjustment  rate would be + or - 0.50% of
average  daily net assets which would be added to or deducted from the basic fee
if a Fund  outperformed  its benchmark  index over a rolling  12-month period by
9.00%  or  more or if it  underperformed  its  benchmark  index  over a  rolling
12-month period.

The chart below shows what the  management  fee rate would be if a Fund  exceeds
its benchmark by the stated amount.

At the end of each month,  the  management fee rate is applied to the net assets
averaged  over the same  12-month  rolling  period  over  which  the  investment
performance of a Fund was measured to determine the monthly management fee.

Numeric is entitled to receive 0.75% of the Emerging Growth Fund's average daily
net assets, computed daily and payable monthly for its advisory services.

The Adviser contractually agreed to limit the Emerging Growth,  Growth, Mid Cap,
and Small Cap Value  Fund's  total  operating  expenses  (other than  investment
advisory fees, shareholder servicing fees, brokerage commissions,  extraordinary
items,  interest  and taxes)  through  December 31, 2006 to the extent that such
expenses exceed 1.25%,  0.50%,  0.50%, and 0.50%,  respectively,  of the average
daily net  assets.  As  necessary,  this  limitation  is  effected in waivers of
advisory  fees and  reimbursements  of expenses  exceeding the advisory fee. The
Funds will not pay  Numeric at a later time for any  amounts it may waive or any
amounts that Numeric has  assumed.  For the six months ended  February 28, 2006,
investment advisory fees were as follows:

FUND                                                        ADVISORY FEES
- ----                                                        -------------
Emerging Growth Fund ..................................       $553,694
Growth Fund ...........................................         73,389
Mid Cap Fund ..........................................         99,151
Small Cap Value Fund ..................................        843,604

During the fiscal year ended August 31, 2004,  the Staff of the  Securities  and
Exchange  Commission  (the "SEC" or "Staff")  notified RBB that the  methodology
used to calculate the  performance-based  investment  advisory fee for the Small
Cap Value Fund,  the Growth Fund and the Mid Cap Fund managed by Numeric did not
comply with the rules under the  Investment  Advisers  Act of 1940,  as amended,
(the "Advisers Act") concerning  performance  fees. The rules under the Advisers
Act  require the  performance  rate to be applied to the average net assets over
the performance  period (a  twelve-month  rolling period for these Funds) rather
than the  average  daily  net  assets  in the  most  recent  month,  as was done
previously.

Applying  the  revised  methodology  to the Small Cap Value  Fund for the period
since the inception of the  performance  fee (January  2001)  indicates that the
Small Cap Value Fund overpaid  Numeric by approximately  $920,000.  In addition,
the Staff  indicated that interest of  approximately  $110,000 was also due from
Numeric on this amount.  During December 2005,  Numeric reimbursed these amounts
to the Small Cap Value  Fund.  With  respect to the Growth  Fund and the Mid Cap
Fund,  application  of the revised  methodology  indicated  that these funds had
underpaid Numeric since the inception of the performance fee. Numeric has agreed
to waive repayment of the underpaid fees.

Effective on September 1, 2004,  the  performance  for all three  aforementioned
funds began to be calculated in accordance with the Advisers Act.

6. SECURITIES LENDING

Loans of securities are required at all times to be secured by collateral  equal
to at least 100% of the market value of the securities on loan.  However, in the
event of default or bankruptcy by the other party to the agreement,  realization
and/or retention of the collateral may be subject to legal  proceedings.  In the
event  that the  borrower  fails to  return  securities,  and  collateral  being
maintained  by  the  lender  is  insufficient  to  cover  the  value  of  loaned
securities,  the borrower is obligated to pay the amount of the  shortfall  (and
interest thereon) to the Funds. However, there can be no assurance the Funds can
recover  this  amount.  The  value  of  securities  on loan to  brokers  and the
aggregate  value of collateral by the Funds and pledged to borrowers at February
28, 2006, were as follows:



                                                                                                  VALUE OF

Collateral  pledged by borrowers for securities out on loan to broker/dealers is

is invested into repurchase  agreements with Bear,  Stearns & Co. Inc., which in
turn are collateralized by various U.S. Treasury securities. The stated interest
rate  on  repurchase  agreements  is net of  rebate  paid  to  the  borrower  on
securities loaned.

GENERAL MARKET COMMENTARY
- --------------------------------------------------------------------------------

Dear Shareholder:

     The stock market  continued  its positive  performance  for the  six-months
ended  February  28, 2006  despite  fears of rising oil  prices.  We have seen a
compression in valuations that has continued into the current market.  In normal
environments,  if such a thing  still  exists,  there is  often a wide  range in
valuations between unprofitable  companies and highly profitable companies.  Not
so today.  The spread in P/E's between  companies that make money and those that
don't is  compressed.  In essence,  investors are not rewarded in today's market
for taking risks,  and this is evident in more than just the U.S. equity market.
This  compression  exists in many segments of the financial  markets  around the
world. In the U.S. we have a flat yield curve in the fixed income market, a lack
of spread  between junk bonds and investment  grade credit,  overseas there is a
lack  of  spread  between  emerging  market   securities  and  developed  market
securities, and, lastly, a lack of spread between large cap stocks and small cap
stocks as measured by the valuations of their indices.

     In this environment we continue to invest in higher quality  companies with
sustainable  growth  prospects.  In our opinion the risk to owning lower quality
companies is simply not one worth taking.

     The  following  pages contain  investment  commentary on each of the Robeco
Investment  Funds.  Please  take a minute to review  and feel free to contact us
with any questions.



Warm Regards,

ROBECO BOSTON PARTNERS SMALL CAP VALUE FUND II (Unaudited)
- --------------------------------------------------------------------------------

Dear Shareholder:

     The Robeco  Boston  Partners  Small Cap Value Fund II  Institutional  Class
returned  7.70% for the  six-month  period ended  February  28,  2006.  The Fund
trailed the Russell 2000(R) Value Index for the period by just over 1%.

     Of the thirteen  economic  sectors,  10 of them contributed to the positive
returns.  Capital  Goods,  Consumer  Services  and  Technology  were the largest
contributors.

     The  portfolio is  constructed  of companies  that  possess  valuation  and
profitability characteristics that are more attractive than the benchmark.

     The Fund remains closed to new investors.


Sincerely,

David Dabora
BP Small Cap Value Fund II Portfolio Manager

ROBECO BOSTON PARTNERS LONG/SHORT EQUITY FUND (unaudited)
- --------------------------------------------------------------------------------

Dear Shareholder:

     The Robeco Boston  Partners  Long/Short Fund  Institutional  Class returned
- -0.75% for the six-month period ended February 28, 2006 trailing the benchmark.

     The major  contributors  on the long side  included  holdings  in  Consumer
Services, Capital Goods and Technology.

     Our  fundamental  analysis has led us to construct a portfolio  which has a
bias towards mid to large capitalized companies on the long side and conversely,
we found more short  opportunities in the smaller  capitalizations  sector.  The
capitalization  bias boded well throughout  2005 as mid to large  capitalization
indices generally outperformed their smaller capitalized counterparts. The early
part  of 2006  has  seen a  reversal  of  this  trend  as  smaller  cap,  highly
speculative  growth  companies  have led the  charge.  We  continue to find more
attractive long term opportunities in the mid to larger  capitalization  segment
of the  market.  This  is  reflected  in the  current  average  weighted  market
capitalization on the long side of $17B and $1.5B on the short side.

     The  long  portfolio  is  attractively  positioned  relative  to the  short
portfolio from both a valuation and profitability standpoint.


Sincerely,

Robert T. Jones
BP Long/Short Equity Fund Portfolio Manager

                                   ----------
Long/Short  Equity is an absolute  return  product that  balances long and short
portfolio   strategies  and  seeks  to  achieve  stable  absolute  returns  with
approximately half the risk of the S&P 500(R). However, this product is not risk
neutral. It is exposed to style, capitalization, sector and short-implementation
risk.  Use of the S&P Index is for  comparative  purposes only since  Long/Short
returns  are not  correlated  to  equity  market  returns.  An  absolute  return
benchmark of 15% is the more appropriate measure for this product.

ROBECO BOSTON PARTNERS LARGE CAP VALUE FUND (unaudited)
- --------------------------------------------------------------------------------

Dear Shareholder:

     The  Robeco  Boston  Partners  Large Cap  Value  Fund  Institutional  Class
returned  7.71% for the six-month  period ended  February 28, 2006 outpacing the
Russell 1000(R) Value Index.

     The  portfolio  had  positive  returns in 12 of the  economic  sectors with
Finance and Technology  leading the way. No sector posted  negative  returns for
the period.

     Our minimal  exposure to the poor  performing  utilities  sector provided a
boost to relative  performance.  We remain  comfortable with our holdings in the
finance sector.  Instead, we own insurance  companies and diversified  financial
service companies.  The revenues of the diversified financial services companies
we own are fee based and not dependent on the direction of interest rates.


Sincerely,

Mark Donovan
BP Large Cap Value Fund Portfolio Manager

ROBECO BOSTON PARTNERS MID CAP VALUE FUND (unaudited)
- --------------------------------------------------------------------------------

Dear Shareholder:

     The  Robeco  Boston  Partners  Mid  Cap  Value  Fund  Institutional   Class
underperformed  the Russell  2500(R) Value Index for the six-month  period ended
February 28, 2006.

     Nine of  thirteen  economic  sectors  contributed  to  performance  for the
quarter with  Consumer  Services,  Finance,  and Capital  Goods leading the way.
Health Care,  Consumer  Durables and  Utilities  were the biggest  detractors on
performance.

     Our  current  focus  continues  to be in  the  consumer  services  sectors,
specifically Services and Non-Durables.  The restaurant industry has provided us
some  interesting  opportunities  and we  continue  to watch this area  closely.
Energy, still a slight overweight in the portfolio,  has been reduced as we sell
into  strength.  The two biggest  underweights  in the portfolio  continue to be
Utilities  and  REITs;  both  are  sectors  where  we fail  to  find  compelling
valuations.


Sincerely,

Steven Pollack
BP Mid Cap Value Fund Portfolio Manager

ROBECO BOSTON PARTNERS ALL-CAP VALUE FUND (unaudited)
- --------------------------------------------------------------------------------

Dear Shareholder:

     The Robeco Boston Partners All-Cap Value Fund  Institutional  Class trailed
the Russell  3000(R)  Value Index for the  six-month  period ended  February 28,
2006.

     Areas of strength for the portfolio  include Finance,  Energy,  and Capital
Goods. The main detractors were Communications and Transportation.

     The portfolio's  all-cap flexibility enabled us to invest in companies that
meet our value based investment  discipline  irrespective of their size. We have
continued to find attractive stock specific opportunities  throughout the market
capitalization  universe.   Within  this  wide  range,  the  portfolio's  market
capitalization profile is currently centered in the mid-to-large cap sphere.

     In a market of narrow spreads among companies of disparate fundamentals, we
have   stock-by-stock   been  investing  in  quality  without   sacrificing  the
portfolio's  valuation core. The attractive  valuation/profitability  profile of
the  portfolio  reflects our  efforts.  We believe the  portfolio is  positioned
favorably.


Sincerely,

Harry Rosenbluth
BP All-Cap Value Fund Portfolio Manager

ROBECO WPG TUDOR FUND (unaudited)
- --------------------------------------------------------------------------------

Dear Shareholder:

     The Robeco WPG Tudor Fund  returned  3.79% for the  six-month  period ended
February 28, 2006, underperforming the benchmark.

     The  Robeco  WPG  Tudor  Fund  underperformed  the  benchmark  due to a few
factors.   There  were  several  stock  specific  company  events  that  led  to
underperformance.  Additionally,  companies  with  market  caps  less  than $250
million  underperformed  during  the  period.  While we were  running at reduced
levels of exposure to  companies  in this market  range as we  anticipated  some
vulnerability,  we were still impacted on an absolute and relative  basis.  This
was  witnessed in the fact that several of our  holdings  announced  significant
positive  news and were not rewarded  with a  corresponding  move in their stock
price.


Regards,

Richard Shuster
WPG Tudor Fund Portfolio Manager

ROBECO WPG LARGE CAP GROWTH FUND (unaudited)
- --------------------------------------------------------------------------------

Dear Shareholder:

     The Robeco  WPG Large Cap  Growth  Fund  returned  6.48% for the  six-month
period ended February 28, 2006,  outperforming  the Russell 1000(R) Growth Index
benchmark.

     The proprietary  quantitative  stock selection model made a strong positive
contribution to performance.

     Stock selection was the primary source of outperformance for the period. At
the sector level,  stocks in the technology and transportation  sectors provided
the strongest  positive  contributions to performance.  Stocks in the industrial
and consumer non-cyclical sectors made the strongest negative contributions.
The individual  stocks making the largest positive  contributions to performance
were Advanced Micro Devices,  Seagate  Technology and Burlington  Northern Santa
Fe; the largest negative contributions came from Kinetic Concepts,  Potash Corp.
and Toll Brothers.

     The Robeco WPG Large Cap Growth  Fund  seeks to  identify  stocks  that are
quantatively  attractive because of rising earnings  expectations,  low relative
valuations  and high share  buybacks.  All stocks in the selection  universe are

Dear Shareholder:

     During the six-month period ended February 28, 2006, the portfolio  trailed
the Lehman Brothers  Aggregate  Index.  The biggest  contribution to performance
during this period came from TIPS (Treasury Inflation Protected Securities). Our
yield curve position  contributed  to performance as we were  underweight in the
poor performing 10 year portion of the curve.

     Corporate bonds made a positive  contribution  to the portfolio  during the
six month  period.  Starting  in  September,  the  portfolio  benefited  from an
overweight in the strong performing  corporate market.  The portfolio shifted to
an  underweight  by the end of the year which helped as the sector  weakened and
spreads widened.

     Mortgage-backed  securities  had little impact on performance at the end of
the year. In January and February,  however,  a 25 basis point overweight to the
index and strong performance in the sector led to a positive contribution.  CMBS
had a modest positive  impact on performance  for the period.  The portfolio was
modestly overweight in the strong performing sector.

     The one sector that detracted from performance  during this time period was
agencies.  During the fourth quarter,  agency spreads  widened,  detracting from
performance  as the portfolio was  overweight.  A shift to an underweight in the
sector  in the first  quarter  contributed  to  performance  as  agency  spreads
continued to widen.

Sid Bakst

FUND EXPENSE EXAMPLES (unaudited)
- --------------------------------------------------------------------------------

As a shareholder of the Fund(s),  you incur two types of costs:  (1) transaction
costs,  redemption  fees;  and (2) ongoing  costs,  including  management  fees,
distribution fees and other Fund expenses. The examples are intended to help you
understand  your  ongoing  costs (in dollars) of investing in the Fund(s) and to
compare these costs with the ongoing costs of investing in other mutual funds.

The examples are based on an investment  of $1,000  invested at the beginning of
the period and held for the period from  September 1, 2005 through  February 28,
2006.

ACTUAL EXPENSES

The first line of the  accompanying  tables  provides  information  about actual
account values and actual  expenses.  You may use the  information in this line,
together  with the amount you  invested,  to estimate the expenses that you paid
over the period.  Simply divide your account  value by $1,000 (for  example,  an
$8,600  account value divided by $1,000 = 8.6),  then multiply the result by the
number in the first  line  under the  heading  entitled  "Expenses  Paid  During
Period" to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The  second  line  of  the  accompanying   tables  provides   information  about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense  ratio and an  assumed  rate of return of 5% per year  before  expenses,
which is not the Fund's  actual  return.  The  hypothetical  account  values and
expenses  may not be used to  estimate  the  actual  ending  account  balance or
expenses you paid for the period.  You may use this  information  to compare the
ongoing costs of investing in the Fund and other funds.  To do so, compare these
5% hypothetical  examples with the 5%  hypothetical  examples that appear in the
shareholder reports of other funds.

Please  note that the  expenses  shown in the  accompanying  tables are meant to
highlight  your ongoing costs only and do not reflect any  transactional  costs,
such as redemption fees.  Therefore,  the second line of the accompanying tables
is useful in comparing  ongoing costs only,  and will not help you determine the
relative  total  costs  of  owning  different  funds.  In  addition,   if  these
transactional costs were included, your costs would have been higher.

(1) These amounts include dividends on securities which the Fund has sold short ("short-sale dividends").  Short-sale
  dividends  generally  reduce the market  value of the  securities  by the amount of the  dividend  declared -- thus
  increasing  the Fund's  unrealized  gain or  reducing  the Fund's  unrealized  loss on the  securities  sold short.
  Short-sale  dividends are treated as an expense,  and increase the Fund's total expense ratio,  although no cash is
  received  or paid by the Fund.  The amount of  short-sale  dividends  was 0.08% of average  net assets for the most
  recent fiscal half-year.

1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     The RBB Fund, Inc. ("RBB" or "Company") was incorporated  under the laws of
the  State of  Maryland  on  February  29,  1988  and is  registered  under  the
Investment  Company Act of 1940,  as amended  (the "1940  Act"),  as an open-end
management  investment  company.  RBB is a "series fund", which is a mutual fund
divided into separate portfolios. Each portfolio is treated as a separate entity
for  certain  matters  under  the  1940  Act,  and  for  other  purposes,  and a
shareholder  of one  portfolio  is not deemed to be a  shareholder  of any other
portfolio. Currently, RBB has seventeen active investment portfolios,  including
Robeco Boston  Partners  Small Cap Value Fund II ("BP Small Cap Value Fund II"),
Robeco Boston Partners  Long/Short  Equity Fund ("BP  Long/Short  Equity Fund"),
Robeco Boston Partners Large Cap Value Fund ("BP Large Cap Value Fund"),  Robeco
Boston  Partners  Mid Cap Value Fund ("BP Mid Cap Value  Fund"),  Robeco  Boston
Partners  All-Cap Value Fund ("BP All-Cap  Value  Fund"),  Robeco WPG Tudor Fund
("WPG  Tudor  Fund"),  Robeco WPG Large Cap Growth  Fund ("WPG  Large Cap Growth
Fund") and Robeco  WPG Core Bond Fund  ("WPG  Core Bond  Fund")  (each a "Fund",
collectively  the "Funds").  As of February 28, 2006, the Boston  Partners Funds
each offer two classes of shares,  Institutional  Class and Investor Class.  The
WPG Tudor and Large Cap Growth  Funds are single class funds  offering  only the
Institutional  Class of  shares.  The Core Bond Fund  offers  three  classes  of
shares, Institutional Class, Investor Class and Retirement Class.

     RBB has  authorized  capital of thirty  billion  shares of common  stock of
which 26.473 billion are currently classified into one hundred and three classes
of common stock.  Each class represents an interest in an active or inactive RBB
investment  portfolio.  The active classes have been grouped into seven separate
"families," six of which have begun investment operations.

     On December  16,  2004,  the Board of  Trustees of the WPG Tudor Fund,  WPG
Large Cap Growth Fund and WPG Core Bond Fund, a series of Weiss,  Peck and Greer
Funds Trust (each a "WPG Fund" and collectively,  the "WPG Funds"),  approved an
Agreement  and Plan of  Reorganization  between each Fund and the Company,  that
provided  for the  tax-free  reorganization  of the  Funds  into  newly  created
portfolios  of the  Company  (the  "New  Funds").  The  Agreement  and  Plan  of
Reorganization was approved by the shareholders,  and, effective after the close
of  business on April 29,  2005.  All of the assets and  liabilities  of the WPG
Funds have been transferred,  in a tax-free  exchange,  to the New Funds and the
shareholders of the WPG Funds have become shareholders of the New Funds.

     PORTFOLIO  VALUATION  -- The Funds' net asset value  ("NAV") is  calculated
once daily at the close of regular  trading  hours on the NYSE  (generally  4:00
p.m.  Eastern time) on each day the NYSE is open.  Securities  held by the Funds
are  valued  using  the  closing  price or the  last  sale  price on a  national
securities  exchange  or on  the  National  Association  of  Securities  Dealers
Automatic  Quotation  System  ("NASDAQ")  market system where they are primarily
traded. If there were no sales on that day or the securities are traded on other
over-the-counter  markets,  the mean of the last bid and ask price  prior to the
market close is used.  Short-term debt securities having a remaining maturity of
60 days or less are amortized to maturity based on their cost.  Debt  securities
having a  remaining  maturity  of  greater  than 60 days are valued by a pricing
service which  utilizes both  dealer-supplied  valuations  and other  techniques
which take into account appropriate factors such as  institutional-size  trading
in similar groups of securities,  yield, quality, coupon rate, maturity, type of
issue,  trading  characteristics  and other market data.  Investments  in mutual
funds are valued at the funds  closing NAV.  With the approval of the  Company's
Board of Directors,  the Funds may use a pricing service,  bank or broker/dealer
experienced in providing  valuations to value the Funds'  securities.  If market
quotations are  unavailable or deemed  unreliable,  securities will be valued by
the Company's Valuation  Committee following  procedures adopted by the Board of
Directors.

     USE OF ESTIMATES -- The  preparation of financial  statements in conformity
with accounting  principles  generally  accepted in the United States of America
requires  management to make estimates and assumptions  that affect the reported
amounts  of assets and  liabilities  and  disclosure  of  contingent  assets and
liabilities at the date of the financial  statements and the reported amounts of
revenues and expenses during the period.  Actual results could differ from those
estimates.

     INVESTMENT TRANSACTIONS, INVESTMENT INCOME AND EXPENSES -- The Funds record
security  transactions  based on trade  date.  The cost of  investments  sold is
determined  by use of the  specific  identification  method  for both  financial
reporting and income tax purposes in  determining  realized  gains and losses on
investments. Interest income is accrued when earned. Dividend income is recorded
on the ex-dividend date.  Distributions  received on securities that represent a
return of  capital  or  capital  gain are  recorded  as a  reduction  of cost of
investments  and/or as a realized  gain.  The Funds  estimate the  components of
distributions received that may be considered return of capital distributions or
capital gain distributions.  The Funds' investment income,  expenses (other than
class  specific  distribution  fees)  and  unrealized  and  realized  gains  and


64 | SEMI-ANNUAL REPORT 2006

NOTES TO FINANCIAL STATEMENTS (unaudited) (continued)
- --------------------------------------------------------------------------------

losses  are  allocated  daily to each class of shares  based  upon the  relative
proportion  of net assets of each class at the  beginning  of the day.  Expenses
incurred on behalf of a specific class, fund or fund family are charged directly
to the  class,  fund or fund  family (in  proportion  to net  assets).  Expenses
incurred for all of the RBB families (such as director or professional fees) are
charged to all funds in proportion  to their net assets of the RBB funds,  or in
such other manner as the Board of Directors  deems fair or  equitable.  Expenses
and fees,  including  investment  advisory and  administration  fees are accrued
daily and taken into account for the purpose of determining  the net asset value
of the Funds.

     DIVIDENDS  AND   DISTRIBUTIONS   TO  SHAREHOLDERS  --  Dividends  from  net
investment income and distributions from net realized capital gains, if any, are
declared and paid at least annually to shareholders  and recorded on ex-date for
all Funds with the exception of the WPG Core Bond Fund which  declares daily and
pays monthly dividends from net investment income.  Income dividends and capital
gain  distributions  are determined in accordance  with U.S.  federal income tax
regulations  which may differ from  generally  accepted  accounting  principles.
These  differences  include the  treatment of  non-taxable  dividends,  expiring
capital loss carryforwards,  foreign currency gain/loss, and losses deferred due
to wash  sales  and  excise  tax  regulations.  Permanent  book  and  tax  basis
differences    relating   to   shareholder    distributions   will   result   in
reclassifications within the components of net assets.

     U.S. TAX STATUS -- No provision is made for U.S.  income taxes as it is the
Funds'  intention  to  continue  to  qualify  for and  elect  the tax  treatment
applicable to regulated  investment companies under Subchapter M of the Internal
Revenue Code of 1986, as amended,  and make the requisite  distributions  to its
shareholders  which will be sufficient to relieve it from U.S. income and excise
taxes.

     OTHER -- In the  normal  course of  business,  the  Funds  may  enter  into
contracts that provide  general  indemnifications.  The Funds' maximum  exposure
under these  arrangements  is  dependent  on claims that may be made against the
Funds in the future,  and,  therefore,  cannot be estimated;  however,  based on
experience, the risk of material loss for such claims is considered remote.

     FOREIGN CURRENCY TRANSLATION -- The books and records of the portfolios are
maintained in U.S. dollars as follows:  (1) the foreign currency market value of
investment  securities  and other  assets  and  liabilities  stated  in  foreign
currencies  are  translated  at the exchange  rate  prevailing at the end of the
period; and (2) purchases, sales, income and expenses are translated at the rate
of  exchange  prevailing  on the  respective  dates  of such  transactions.  The
resulting exchange gains and losses are included in the Statement of Operations.

     FOREIGN  SECURITIES -- There are certain risks  resulting from investing in
foreign  securities  in  addition  to  the  usual  risks  inherent  in  domestic
investments. Such risks include future political, economic and currency exchange
developments including investment restrictions and changes in foreign laws.

     FORWARD  CURRENCY  CONTRACTS -- The Funds may enter into  forward  currency
contracts.  Such contracts may be utilized in connection with planned  purchases
or sales  of  securities  or to  hedge  the  U.S.  dollar  value  of  portfolios
denominated  in foreign  currencies.  Fluctuations  in the value of the  forward
contracts  are recorded as  unrealized  gains or losses by the Funds.  Risks may
arise upon  entering  into  these  contracts  from the  potential  inability  of
counterparties  to meet  the  terms of their  contracts  and from  unanticipated
movements in the value of the foreign currency relative to the U.S. dollar. Upon
entering into such a contract, the Fund is required to segregate assets with its
custodian  at  least  equal to the  value  of the  Fund's  assets  committed  to
fulfilling the forward  currency  contract.  At February 28, 2006, the Funds did
not hold any forward currency contracts.

     FUTURES  -- The WPG Tudor  Fund and the WPG Core  Bond Fund may enter  into
futures contracts. A futures contract is an agreement between two parties to buy
and sell a security at a set price on a future date.  Upon  entering into such a
contract,  a Fund is  required  to pledge to the broker an amount of cash and/or
securities equal to the minimum "initial margin" requirements of the exchange on
which such  contract  is traded.  Pursuant to the  contract,  the Fund agrees to
receive  from,  or pay to the  broker,  an  amount  of cash  equal to the  daily
fluctuation  in value of the  contract.  Such a receipt of payment is known as a
"variation  margin" and is recorded by each Fund as an unrealized  gain or loss.
When the contract is closed,  the Fund records a realized  gain or loss equal to
the  difference  between the value of the contract at the time it was opened and
the  value  at the  time it was  closed.  The  Fund is also  required  to  fully
collateralize  futures  contracts  purchased.  The Fund only enters into futures
contracts which are traded on exchanges. At February 28, 2006, the Funds did not
hold any futures.


                                                    SEMI-ANNUAL REPORT 2006 | 65

     LINE OF CREDIT -- Each Robeco Boston  Partners Fund may borrow an amount up
to its  prospectus-defined  limitations,  from a  committed  line of  credit  of
$5,000,000  available to the Funds in the Robeco  Boston  Partners  Fund Family.
Borrowings from the line of credit will bear interest at the Federal Funds Rate.
The Funds had no  outstanding  borrowings  at  February  28, 2006 or at any time
during the six-months ended February 28, 2006.

     MORTGAGE  DOLLAR  ROLLS  (WPG CORE BOND FUND) -- The WPG Core Bond Fund may
enter into  mortgage  dollar  rolls in which WPG Core Bond Fund  sells  mortgage
securities  for delivery in the current  month and  simultaneously  contracts to
repurchase similar,  but not identical,  securities at an agreed upon price on a
fixed date.  The WPG Core Bond Fund  accounts for such dollar rolls as purchases
and  sales  and  records  an  unrealized  gain or loss  each  day  equal  to the
difference  between the original  value of the  purchase and the current  market
value. The WPG Core Bond Fund must maintain liquid securities having a value not
less than the  repurchase  price  (including  accrued  interest) for such dollar
rolls.  Losses  may arise due to changes  in value of the  securities  or if the
counterparty  does  not  perform  under  the  terms  of  the  agreement.  If the
counterparty files for bankruptcy or becomes insolvent, the WPG Core Bond Fund's
right to repurchase or sell securities may be limited.

     OPTIONS -- The BP All-Cap Value Fund,  WPG Tudor Fund, WPG Large Cap Growth
Fund and WPG Core Bond Fund may buy put and call options and write  covered call
and secured put options.  Such options may relate to  particular  securities  or
domestic  stock indices,  and may or may not be listed on a domestic  securities
exchange or issued by the Options  Clearing  Corporation.  The risk in writing a
call option is that the Fund gives up the  opportunity  for profit if the market
price of the  security  increases.  The risk in writing a put option is that the
Fund may incur a loss if the  market  price of the  security  decreases  and the
option is  exercised.  The risk in  purchasing an option is that the Fund pays a
premium whether or not the option is exercised. The Fund also has the additional
risk of being unable to enter into a closing  transaction at an acceptable price
if  a  liquid  secondary  market  does  not  exist.  The  Fund  also  may  write
over-the-counter options where completing the obligation depends upon the credit
standing of the other party.  Option  contracts  also involve the risk that they
may result in loss due to  unanticipated  developments  in market  conditions or
other causes.

     Options purchased are recorded as an asset and written options are recorded
as liabilities  to the extent of premiums paid or received.  Gains or losses are
realized  when the  option  transaction  expires  or  closes.  When an option is
exercised,  the proceeds on sales for a written call option,  the purchase  cost
for a written put option or the cost of a security  for a purchased  put or call
option is adjusted by the amount of the premium received or paid.

     The BP All-Cap Value Fund had  transactions  in options  written during the
six-months ended February 28, 2006 as follows:

                                                      NUMBER OF       PREMIUMS

                                                      ---------       --------
Options outstanding at August 31, 2005                    89          $ 31,116
Options written                                          124            49,832
Options exercised                                        (95)          (29,656)
                                                         ---          --------
Options outstanding at February 28, 2006                 118          $ 51,292
                                                         ---          --------

     SHORT SALES -- In the BP  Long/Short  Equity Fund and the BP All-Cap  Value
Fund, when the Investment Adviser believes that a security is overvalued, it may
sell the security  short by borrowing  the same  security from a broker or other
institution and selling the security.  A Fund will incur a loss as a result of a
short sale if the price of the borrowed  security  increases between the date of
the short sale and the date on which the Fund buys and  replaces  such  borrowed
security.  A Fund  will  realize  a gain if there is a  decline  in price of the
security between those dates where decline exceeds costs of the borrowing of the
security and other transaction costs. There can be no assurance that a Fund will
be able to close out a short position at any particular time or at an acceptable
price.  Although  a Fund's  gain is  limited  to the  amount  at which it sold a
security short, its potential loss is unlimited in size. Until a Fund replaces a
borrowed  security,  it  will  maintain  at  all  times  cash,  U.S.  Government
securities,  or other liquid  securities in an amount  which,  when added to any
amount  deposited with a broker as  collateral,  will at least equal the current
market value of the security  sold short.  Depending on  arrangements  made with
brokers, a Fund may not receive any payments (including  interest) on collateral
deposited with them.

2.   TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

     Boston Partners Asset Management,  LLC ("Boston Partners"),  a wholly owned
subsidiary  of  Robeco  Investment  Management,  USA,  serves  as the BP  Funds'
Investment  Adviser.  For its advisory services,  Boston Partners is entitled to

     Boston  Partners  contractually  agreed to limit a Fund's  total  operating

                                 .80% of net assets $300 million to $500 million

capped at 1.70%,  WPG Large Cap Growth Fund's expenses are capped at 1.40%,  and

beginning in 2004,  WPG may seek  reimbursement  from the WPG Tudor Fund and WPG
Large Cap Growth Fund for  expenses  waived by WPG during the prior two years to
the extent that such  recovery  would not cause the affected  fund to exceed the
expense limitations in effect at the time of recovery. At February 28, 2006, the
amounts  potentially  recoverable  by WPG from the WPG  Large  Cap  Growth  Fund
pursuant to this  agreement are $42,989  expiring  December 31, 2006 and $54,529

     At August 31, 2005,  the WPG Core Bond Fund had capital loss  carryforwards
of $2,731,098 available to offset future capital gains which expire in 2007.

     During the year ended August 31, 2005, the BP Large Cap Value Fund utilized
$3,129,974 of prior capital loss  carryforwards,  the BP Long/Short  Equity Fund
utilized $7,780,009 of prior capital loss  carryforwards,  and the WPG Core Bond
Fund utilized $360,085 of prior capital loss carryforwards.

     Under Federal tax law,  foreign  currency and capital losses realized after
October 31 may be deferred and treated as having  arisen on the first day of the
following  fiscal  year.  For the year  ended  August  31,  2005,  there were no
post-October  capital losses or  post-October  currency  losses  incurred by the
Funds.   The  differences   between  the  book  and  tax  basis   components  of
distributable earnings relate principally to the timing of recognition of income
and gains for federal income tax purposes. Short-term and foreign currency gains
are reported as ordinary income for federal tax purposes.


8.   IN-KIND REDEMPTION

     During  the year  ended  August  31,  2005,  the BP Large  Cap  Value  Fund

redemption.  The  shareholder  received a  pro-rata  portion of the BP Large Cap
Value Fund's  holdings.  The value of the redemption was  $7,471,816,  (of which
$1,185,294 was a realized gain for financial reporting purposes).  Institutional
shares of 581,012  were  redeemed  from the BP Large Cap Value Fund as a part of
this transaction.  This transaction was completed following  guidelines approved
by the Board of Directors.

AMENDED AND RESTATED INVESTMENT ADVISORY AGREEMENTS: ROBECO BOSTON PARTNERS
FUNDS

     As required by the 1940 Act,  the Board of Directors  (the  "Board") of the
Company,  including all of the Directors who are not "interested persons" of the
Company, as that term is defined in the 1940 Act (the "Independent  Directors"),
considered the approval of amended and restated  investment  advisory agreements
between Boston Partners Asset  Management,  L.L.C.  ("Boston  Partners") and the
Company   (each  an  "Amended   Agreement"   and   collectively,   the  "Amended
Agreements"),  on behalf of the Robeco Boston  Partners Large Cap Value Fund and
the Robeco Boston  Partners  All-Cap Value Fund (each a "Fund" and  collectively
the  "Funds"),  at a meeting of the Board held on  February  15, 2006 (the "2006
Meeting").  The Directors noted that the annual review and renewal of the Funds'
investment advisory  agreements ("Prior  Agreements") had been considered at the
meeting of the Board held on May 25,  2005 (the  "2005  Meeting"),  and that the
Amended  Agreements  were being  considered  as a result of reductions by Boston
Partners  in the  contractual  advisory  fee rates  payable  by the  Funds.  The
Directors  also  noted  that  the  annual  review  and  renewal  of the  Amended
Agreements  would be  considered  at the meeting of the Board of Directors to be
held on May 25, 2006.

     At the 2006 Meeting,  the Board approved the Amended  Agreements for a term
ending on August 16, 2006 and renewed annually thereafter.  The Board's decision
to approve the Amended Agreements reflects the exercise of its business judgment
to continue the existing  arrangement  with Boston  Partners with respect to the
Funds at reduced  contractual  advisory  fee rates.  In  approving  the  Amended
Agreements, the Board considered information provided by Boston Partners at both
the 2005 Meeting and the 2006 Meeting with the  assistance and advice of counsel
to the Independent Directors and the Company. In considering the approval of the
Amended Agreements, the Directors took into account all materials provided prior
to and during the 2005  Meeting and the 2006  Meeting,  the  presentations  made
during the 2005  Meeting  and the 2006  Meeting,  and the  discussions  with the
Adviser  during the 2005 Meeting and the 2006 Meeting.  The Directors  noted the
factors that they had considered in connection with their review and approval of
the Prior  Agreements at the 2005 Meeting as well as  information on the reduced
contractual  advisory  fee  rates  for the  Funds  and  related  changes  in the
Adviser's  advisory fee waiver and expense  reimbursement  arrangements  for the
Funds  discussed at the 2006  Meeting.  No one factor was  determinative  in the
Board's  consideration  of the Amended  Agreements.  The  Directors  then met in
executive session with counsel to discuss and consider information  presented in
connection with the approval of the Amended Agreements as well as the Directors'
responsibilities and duties in approving the Amended Agreements.

     The Directors evaluated the reduction in the contractual  advisory fee rate
for the Robeco Boston Partners  All-Cap Value Fund,  noting that the contractual
advisory  fee rate would be reduced to 0.80% from 1.00% of average  net  assets.
The Directors also  considered  that for the one-year  period ended December 31,
2005, the Fund had  outperformed  its  benchmark.  The Directors then noted that
Boston   Partners  also  had  agreed  to  modify  its  fee  waiver  and  expense
reimbursement  arrangements  for the Fund to limit  the total  annual  operating
expenses  for the Fund's  Investor  Class and  Institutional  Class to 1.20% and
0.95%,   respectively,   of  average  net  assets  through  December  31,  2006.
Previously,  Boston Partners had waived its advisory fee and reimbursed expenses
to limit the total annual  operating  expenses of the Fund's  Investor Class and
Institutional Class to 1.50% and 1.25%, respectively, of average net assets. The
Directors  considered  and  assessed  the  reasons  for  the  reduction  in  the
contractual  advisory  fee rate and the overall  impact of the  reduction on the
performance of the Fund relative to its benchmark.

     The Directors then evaluated the reduction in the contractual  advisory fee
rate of the  Robeco  Boston  Partners  Large Cap  Value  Fund,  noting  that the
contractual  advisory  fee rate  would be reduced to 0.60% from 0.75% of average
net assets.  The Directors also  considered  that for the one-year  period ended
December 31, 2005, the Fund had outperformed  its benchmark.  The Directors then
noted that  Boston  Partners  had agreed to modify its  advisory  fee waiver and
expense  reimbursement  arrangements  for the Fund to  limit  the  total  annual
operating expenses of the Fund's Investor Class and Institutional Class to 1.00%
and 0.75%,  respectively,  of average  net assets  through  December  31,  2006.
Previously,  Boston Partners had waived its advisory fee and reimbursed expenses
to limit the total annual  operating  expenses of the Fund's  Investor Class and
Institutional Class to 1.25% and 1.00%, respectively, of average net assets. The
Directors  considered  and  assessed  the  reasons  for  the  reduction  in  the
contractual  advisory  fee rate and the overall  impact of the  reduction on the
performance of the Fund relative to its benchmark.

     The Directors then  determined,  considering the  information  presented at
both the 2005 Meeting and the 2006 Meeting,  that the nature, extent and quality
of  the  services  provided  by  Boston  Partners  in  advising  the  Funds  was
satisfactory;  the profits earned by Boston Partners seemed reasonable;  and the
benefits  derived by Boston Partners from managing the Funds,  including its use
of soft dollars and the way it selects brokers, seemed reasonable. The Directors
discussed  and  considered  any  economies-of-scale  realized  by each Fund as a
result of asset growth.  Based on all of the information  presented to the Board
and its consideration of relevant factors, the Board concluded that the fee paid
to the Adviser by each Fund was reasonable,  and in the exercise of its business
judgment that the Amended Agreements be approved.

                     SEMI-ANNUAL INVESTMENT ADVISER'S REPORT
                                FEBRUARY 28, 2006


Dear Fellow Shareholder:

   We are pleased to provide you with the  semi-annual  report for The Schneider
Funds for the six months ended February 28, 2006.

INVESTMENT CLIMATE

   "It takes a licking  and keeps on  ticking".....despite  a backdrop of rising
short-term interest rates, energy costs and inflation concerns, healthy economic
and corporate  earnings  growth led U.S.  equities to moderate  gains during the
period.  The Russell 3000(R) Index,  which measures the performance of the broad
U.S.  equity market,  posted a 6.6% return for the six months ended February 28,
2006.   Small   capitalization   stocks   continued  their  six-year  streak  of
outperformance versus large caps.

   The past four years have marked a notable  period of  sustained,  above-trend
growth in the U.S. economy and corporate profits.  However,  it appears that the
domestic  economy is currently in transition to a slower-growth  environment led
by softness in consumer spending.

   We believe that positive momentum in the global economy will be sufficient to
offset the dampening  effect of the Fed's  interest rate  increases.  GDP growth
outside the U.S.  should be well above 3% in 2006,  keeping the world economy on
track for its fourth consecutive year of above-trend growth. As a result, we are
favorably  inclined  toward  businesses  that can generate  top-line growth from
non-U.S. demand.

Strong  corporate  balance sheets should provide an impetus for further dividend
increases, share buybacks and acquisitions in 2006, but we think that there will
also be a continued pickup in capital  expenditures.  For this reason, the Funds
continue to have exposure to  later-stage  capital goods stocks as we expect the
days of open-ended consumer demand to draw to a close.

SCHNEIDER SMALL CAP VALUE FUND -- INVESTMENT REVIEW AND PORTFOLIO STRATEGY

   The Small Cap Value Fund  produced  favorable  results  during the six months
ended February 28, 2006,  returning 9.75% versus 8.80% for the benchmark Russell
2000(R)  Value  Index.  Since  inception  on  September  2,  1998,  the Fund has
performed  exceptionally  well in  delivering  a 29.1%  annualized  total return
versus 14.7 % for the index.

   The Fund has made  successful  investments  in companies  that are benefiting
from the  cyclical  upswing in the office  real estate  market.  EMCOR Group and
Jones Lang LaSalle were notably strong  performers  during the period. We expect
to see the  industry's  improving  health  lead to  favorable  trends in leasing
activity, property transactions and new construction.

   B/E Aerospace,  the largest Fund position and a successful long-term holding,
made a major contribution  during the past six months. We purchased the stock in
2003 in anticipation of an upswing in the commercial aerospace cycle that is now
on firm  footing.  The order cycle for  commercial  aircraft  continues  to look
bright,  and we also expect the  company's  backlog to expand from airlines that
are retrofitting their international first-class seating.

                               THE SCHNEIDER FUNDS
               SEMI-ANNUAL INVESTMENT ADVISER'S REPORT (CONTINUED)
                                FEBRUARY 28, 2006


   We have increased the Fund's commitment to financial stocks,  although we are
still  underweighted  relative  to the  benchmark.  The  current  interest  rate
environment has exerted downward  pressure on select financials and provided the
opportunity to invest in Anworth  Mortgage Asset and Deerfield  Triarc  Capital.
These REITs invest in mortgage-backed  securities that are sensitive to interest
rate fluctuations,  but are not exposed to credit risk. We expect their earnings
to benefit as the yield curve returns to a more normal long-term relationship.

SCHNEIDER VALUE FUND -- INVESTMENT REVIEW AND PORTFOLIO STRATEGY

   Results  for the Value Fund fell short of the  benchmark  over the six months
ended February 28, 2006,  returning  5.19% versus 7.33% for the Russell  1000(R)
Value  Index.  Since the  inception  date of September  30,  2002,  the Fund has
performed exceedingly well in delivering a 29.08% annualized total return versus
19.77% for the benchmark.

   A number of success stories such as CSX Corp.,  AON Corp. and Tate & Lyle PLC
were  outweighed  by the  more  significant  drop in a few  portfolio  holdings,
particularly  Reliant Energy, and also Visteon Corp. and Liberty Global. We feel
confident that these  undervalued  companies can  eventually  realize their true
earnings potential, gain investor favor and rebound in price.

   Reliant Energy operates two unrelated  businesses:  an unregulated  wholesale
power generation  business centered primarily in the mid-Atlantic  region, and a
deregulated  retail  power  supply  business  in  Texas.  We  made  our  initial
investment  in 2003 in  anticipation  of a  long-term  cyclical  rebound  in the
wholesale power market,  and our investment case is right on track.  Electricity
demand  is  growing  at a faster  rate  than  supply in  Reliant's  key  markets
(Mid-Atlantic,  California,  Texas), and the company is poised for a recovery in
operating  margins that should become evident as 2007 comes more into focus. The
stock,  a top performer for the Fund in 2003 and 2004,  pulled back last October
when  temporary  troubles  at the  Texas  retail  unit  resulted  in a poor 2006
earnings  outlook.  It is a very cheap  stock  relative to net asset  value.  We
believe that investor  confidence will eventually be restored,  and it remains a
top holding in the portfolio.

   During  the period our  exposure  to the  Financial  Services  sector  nearly
doubled,  although  we remain  underweighted  relative to the  benchmark  index.
Rising rates and a flat yield curve have exerted pressure on select  financials.
This  environment  enabled us to increase  our  exposure  through new names like
Annaly Mortgage  Management,  a REIT that invests in mortgage-backed  securities
with no credit risk, and Countrywide  Financial,  which is engaged  primarily in
residential mortgage banking and related businesses.

   We also  added to our  position  in  Fannie  Mae.  We  believe  the  stock is
undervalued  relative to its peak  earning  power,  and we  anticipate  improved
returns  from both its  mortgage  guaranty  business  and  investment  portfolio
holdings.

   We appreciate your continuing support of the Funds.

                              FUND EXPENSE EXAMPLES
                                   (UNAUDITED)


As a shareholder of the Fund(s),  you incur two types of costs:  (1) transaction
costs,  including  redemption fees; and (2) ongoing costs,  including management
fees and other Fund expenses. These examples are intended to help you understand
your ongoing costs (in dollars) of investing in the Fund(s) and to compare these
costs with the ongoing costs of investing in other mutual funds.

These examples are based on an investment of $1,000 invested at the beginning of
the period and held for the period from  September 1, 2005 through  February 28,
2006.


ACTUAL EXPENSES

The first line of the  accompanying  tables  provides  information  about actual
account values and actual  expenses.  You may use the  information in this line,
together  with the amount you  invested,  to estimate the expenses that you paid
over the period.  Simply divide your account  value by $1,000 (for  example,  an
$8,600  account value divided by $1,000 = 8.6),  then multiply the result by the
number in the first  line  under the  heading  entitled  "Expenses  Paid  During
Period" to estimate the expenses you paid on your account during this period.


HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The  second  line  of  the  accompanying   tables  provides   information  about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense  ratio and an  assumed  rate of return of 5% per year  before  expenses,
which is not your Fund's actual  return.  The  hypothetical  account  values and
expenses  may not be used to  estimate  the  actual  ending  account  balance or
expenses you paid for the period.  You may use this  information  to compare the
ongoing costs of investing in the Fund and other funds.  To do so, compare these
5% hypothetical  examples with the 5%  hypothetical  examples that appear in the
shareholder  reports of other funds.

Please  note that the  expenses  shown in the  accompanying  tables are meant to
highlight  your ongoing costs only and do not reflect any  transactional  costs,
such as redemption fees.  Therefore,  the second line of the accompanying tables
is useful in comparing  ongoing costs only,  and will not help you determine the
relative  total  costs  of  owning  different  funds.  In  addition,   if  these
transactional costs were included, your costs would have been higher.

*  Expenses  are equal to an  annualized  expense  ratio of 1.10% for the  Schneider  Small Cap Value Fund and 0.85% for the
   Schneider Value Fund, which includes waived fees or reimbursed expenses, multiplied by the average account value over the
   period,  multiplied by the number of days in the most recent fiscal half-year  (181),  then divided by 365 to reflect the
   one-half  year period.  The Fund's  ending  account  values on the first line in each table are based on the actual total
   return for each Fund of 9.75% for the Schneider Small Cap Value Fund and 5.19% for the Schneider Value Fund.

the  State of  Maryland  on  February  29,  1988  and is  registered  under  the
Investment  Company Act of 1940,  as amended  (the "1940  Act"),  as an open-end
management  investment  company.  RBB is a "series fund," which is a mutual fund
divided into separate portfolios. Each portfolio is treated as a separate entity
for  certain  matters  under  the  1940  Act,  and  for  other  purposes,  and a
shareholder  of one  portfolio  is not deemed to be a  shareholder  of any other
portfolio. Currently, RBB has seventeen active investment portfolios,  including
the  Schneider  Small  Cap Value  Fund (the  "Small  Cap  Value  Fund")  and the
Schneider  Value  Fund  (the  "Value  Fund")  (each a "Fund",  collectively  the
"Funds"),  which  commenced  investment  operations  on  September  2,  1998 and
September 30, 2002,  respectively.  As of the date hereof,  each Fund offers the
Institutional Class.

   RBB has authorized  capital of thirty billion shares of common stock of which
26.473  billion are currently  classified  into one hundred and three classes of
Common  Stock.  Each class  represents  an interest in an active or inactive RBB
investment  portfolio.  The active classes have been grouped into seven separate
"families," six of which have begun investment operations.

   PORTFOLIO  VALUATION -- The Funds' net asset value ("NAV") is calculated once
daily at the  close of  regular  trading  hours on the New York  Stock  Exchange
("NYSE")  (generally  4:00  p.m.  Eastern  time)  on each  day the NYSE is open.
Securities held by the Funds are valued using the closing price or the last sale
price on a  national  securities  exchange  or on the  National  Association  of
Securities  Dealers  Automatic  Quotation System  ("NASDAQ") market system where
they are primarily  traded. If there were no sales on that day or the securities
are traded on other  over-the-counter  markets, the mean of the last bid and ask
prices prior to the market close are used.  Short-term debt securities  having a
remaining  maturity of 60 days or less are amortized to maturity  based on their
cost.  Debt securities  having a remaining  maturity of greater than 60 days are
valued at the mean  between  the bid and ask prices.  If the Funds hold  foreign
equity securities,  the calculation of the Funds' NAV will not occur at the same
time as the  determination of the value of the foreign equity  securities in the
Funds'  portfolio,  since  these  securities  are traded on  foreign  exchanges.
Investments  in mutual  funds are  valued at the  funds  closing  NAV.  With the
approval  of the  Company's  Board of  Directors,  the  Funds  may use a pricing
service, bank or broker/dealer  experienced in providing valuations to value the
Funds'  securities.  If market quotations are unavailable or deemed  unreliable,
securities will be valued by the Funds' Valuation Committee following procedures
adopted by the Board of Directors.

   USE OF ESTIMATES -- The  preparation  of financial  statements  in conformity
with accounting  principles  generally accepted in the United States of America,
requires  management to make estimates and assumptions  that affect the reported
amounts  of assets and  liabilities  and  disclosure  of  contingent  assets and
liabilities at the date of the financial  statements and the reported amounts of
revenues and expenses during the period.  Actual results could differ from those
estimates.

   REPURCHASE  AGREEMENTS -- The Funds may purchase  securities  from  financial
institutions  subject  to  the  seller's  agreement  to  repurchase  them  at an
agreed-upon time and price ("repurchase agreements"). The financial institutions
with whom a Fund enters into repurchase  agreements are banks and broker/dealers
that  Schneider   Capital   Management,   LP  ("Adviser"  or  "SCM")   considers
creditworthy.  The seller  under a  repurchase  agreement  will be  required  to
maintain the value of the securities as collateral,  subject to the agreement at
not less than the repurchase  price plus accrued  interest.  SCM marks to market
daily the value of the  collateral,  and, if  necessary,  requires the seller to
deposit  additional  securities  by the next Fund  business  day.  Default by or
bankruptcy of the seller would, however,  expose a Fund to possible loss because

                          FEBRUARY 28, 2006 (UNAUDITED)


of adverse  market action or delays in connection  with the  disposition  of the
underlying securities. For the six months ended February 28, 2006, the Funds did
not enter into any repurchase agreements.

   INVESTMENT TRANSACTIONS,  INVESTMENT INCOME, AND EXPENSES -- Transactions are
accounted for on the trade date. The cost of  investments  sold is determined by
use of the  specific  identification  method for both  financial  reporting  and
income tax purposes in  determining  realized  gains and losses on  investments.
Interest  income is  accrued  as  earned.  Dividend  income is  recorded  on the
ex-dividend date.  Distributions  received on securities that represent a return
of capital or capital gain are  recorded as a reduction  of cost of  investments
and/or as a realized gain.  The fund  estimates the components of  distributions
received that may be considered return of capital  distributions or capital gain
distributions.  Expenses  incurred on behalf of a specific  class,  fund or fund
family are charged directly to the class,  fund or fund family (in proportion to
net assets).  Expenses incurred for all of the RBB families (such as director or
professional  fees) are charged to all funds in  proportion to their average net
assets of the RBB funds, or in such other manner as the Board of Directors deems
fair  or  equitable.  Expenses  and  fees,  including  investment  advisory  and
administration fees, are accrued daily and taken into account for the purpose of
determining the net asset value of the Funds.

   FOREIGN  CURRENCY  TRANSLATION  --  Foreign  securities,   other  assets  and
liabilities are valued using the foreign currency exchange rate effective at the
end of the reporting  period.  The books and records of the Funds are maintained
in U.S. dollars. Cost of investments is translated at the currency exchange rate
effective  at the  trade  date.  The gain or loss  resulting  from a  change  in
currency  exchange rates between the trade and  settlement  dates of a portfolio
transaction is treated as a gain or loss on foreign currency. Likewise, the gain
or loss resulting  from a change in currency  exchange  rates,  between the date
income is accrued and paid, is treated as a gain or loss on foreign currency.

   DIVIDENDS AND  DISTRIBUTIONS TO SHAREHOLDERS -- Dividends from net investment
income and distributions  from net realized capital gains, if any, are declared,
recorded on ex-date and paid at least annually to shareholders. Income dividends
and capital gain  distributions  are determined in accordance with U.S.  federal
income tax  regulations,  which may differ from  generally  accepted  accounting
principles.  These differences  include the treatment of non-taxable  dividends,
expiring capital loss carryforwards,  foreign currency gain/loss,  partnerships,
and losses deferred due to wash sales and excise tax regulations. Permanent book
and tax basis differences  relating to shareholder  distributions will result in
reclassifications within the components of net assets.

   U.S. TAX STATUS -- No  provision is made for U.S.  income taxes as it is each
Fund's  intention  to  continue  to  qualify  for and  elect  the tax  treatment
applicable to regulated  investment companies under Subchapter M of the Internal
Revenue Code of 1986, as amended,  and make the requisite  distributions  to its
shareholders  which will be sufficient to relieve it from U.S. income and excise
taxes.

   OTHER -- In the normal course of business, the Funds may enter into contracts
that provide general  indemnifications.  The Funds' maximum exposure under these
arrangements  is  dependent  on claims that may be made against the Funds in the
future, and, therefore,  cannot be estimated;  however, based on experience, the
risk of material loss for such claims is considered remote.

  As of August 31, 2005, the components of distributable earnings on a tax basis
were as follows:

   At August 31, 2005, the Funds had no capital loss carryforwards  available to
offset future capital gains.

   Under Federal tax law,  foreign  currency and capital  losses  realized after
October 31 may be deferred and treated as having  arisen on the first day of the
following fiscal year. For the six months ended February 28, 2006, there were no
post-October  losses incurred in the Funds. The differences between the book and
tax basis components of distributable  earnings relate principally to the timing
of recognition  of income and gains for federal income tax purposes.  Short-term
and foreign  currency  gains are  reported  as  ordinary  income for federal tax
purposes.

6. IN KIND TRANSFER OF SECURITIES

   For the six months ended February 28, 2006, the Schneider Value Fund received

                             SMALL CAP GROWTH FUND
       SEMIANNUAL REPORT FOR THE SIX-MONTH PERIOD ENDED FEBRUARY 28, 2006
- --------------------------------------------------------------------------------

Fellow Shareholder:

Beating its benchmark in all six months of the semiannual  period ended February
28,  2006,  the  Bogle  Small Cap  Growth  Fund (the  "Fund")  outperformed  the
benchmark Russell 2000(R) by +9.11%*,  returning +19.34% for the Investor shares
and +19.39% for the Institutional shares. The unmanaged Russell 2000(R) Index of
smaller  companies  gained  +10.23% over the six-month time period (all of these
results  are  unannualized).  The Fund's  latest  stretch of  positive  relative
performance,  which began in December  of 2004 and  extended  through the end of
this latest  reporting  period,  is attributed to positive  performance from all
three of our primary  investment  models and  positive  stock  selection in most
sectors,  including  robust relative  performance in the technology  sector.  As
shown in the  chart  below,  the  Fund has  outperformed  its  benchmark  in all
multi-year periods since inception in 1999. With the exception of 2004, the Fund
has also stayed ahead of its benchmark in each calendar year since inception.

The recent market environment is discussed in more detail in the next section of
this  letter.  This is  followed  by  performance  attribution  analysis,  which
explains the results  generated by our  investment  models during the semiannual
period,  illustrating sources of value added with a few stock specific examples.
We then  present  key  fundamental  characteristics  of the Fund and  benchmark,
highlighting  the Fund's  likeness to the  benchmark  due to our risk  controls.
Finally, we close with an update on developments at Bogle Investment Management,
L.P.

                                       1

MARKET ENVIRONMENT. U.S. equity market performance was generally positive in the
semiannual  reporting period. The last four months of 2005 saw modestly positive
performance,  as  negative  results  through  October  were more than  offset by
positive  performance  in November and December.  The lack of a strong  year-end
rally,  when compared to the year-end rallies of the last few years,  likely set
the stage for the strong  market  bounce  experienced  in  January of 2006.  The
bounce was  notably  pronounced  in small cap  stocks,  and  indeed  much of the
semiannual period performance for the benchmark occurred in January (the Russell
2000(R) advanced +8.97% in this month alone). All Russell(R) market sub-segments
ended the semiannual period in positive territory.  Small capitalization  stocks
fared  particularlY  well during the  six-month  period,  due primarily to their
strong  January  performance,  as the Russell  2000(R) Index  returned  +10.23%,
compared  with a +6.20% return for the Russell  1000(R) Index of larger  stocks.
Within small  capitalization  stocks,  growth outperformeD value by nearly three
percentage  points  overall and in four out of the six months of the  semiannual
period.  For the six months ended February 28, 2006, the Russell  2000(R) Growth
advanced  +11.69%,  while the  Russell  2000(R)  Value  gained  +8.80%.  Despite
continUed  macroeconomic  uncertainty  (related  to  concerns  about  rising oil
prices, interest rates, and future corporate earnings growth), the Fund's recent
performance  indicates  to us  that  investors  are  paying  some  attention  to
stock-specific  fundamentals.  Further,  the recent  performance of our earnings
expectations model,  specifically during earnings announcement periods, suggests
to us that  earnings  trends  have  been  sustainable  over the last  twelve  to
fourteen  months,  and particularly  for those companies  applying  conservative
accounting techniques.

PERFORMANCE ATTRIBUTION.  According to our return attribution analysis, positive
stock selection accounted for nearly all of the Fund's  outperformance  relative
to its benchmark in the semiannual period.  Recall that our three primary models
seek to identify the following:  1) stocks that have demonstrated the ability to
produce earnings growth (the earnings  expectations model); 2) companies that do
not have to manufacture earnings growth through aggressive accounting (financial
quality model);  and 3) stocks that trade at attractive  valuations  relative to
their most similar peers (relative  valuation model). In the most recent period,
the Fund benefited from positive  contributions from all three models,  with the
strongest contribution coming from the earnings expectations model. The earnings
expectations  and the financial  quality models also helped us avoid stocks with
poor earnings and  operational  trends.  The  combination of the models provided
robust returns, as stock selection added approximately nine percentage points of
value over the benchmark  return for the six-month  period.  Stock selection was
strongest  in  energy,  industrial  and  technology  stocks,  while the  largest
contribution  to return  came from stock  selection  within the  technology  and
financial sectors. Note that these two sectors currently represent a little more
than 40% of both the Fund's and benchmark's allocations.

At the end of the  semiannual  period,  the Fund held 176 stocks and the largest
holding  represented 1.2% of portfolio assets. This  diversification  limits the
impact any single stock can have on total Fund performance. Despite this lack of
portfolio   concentration,   it  is  interesting   to  look  at   stock-specific
illustrations  of  investment  performance  during  the  reporting  period.  For
example,  Xyratex Ltd., a company providing network storage subsystem technology
as well as disk drive  process and test  technology,  looked  attractive  from a
relative valuation and financial quality perspective at the start of this latest
semiannual  period.  Price  performance  started to improve in November,  and in
January the company  announced strong earnings,  surpassing  expectations.  From
early  November  through the end of February,  the stock advanced more than 80%.
Core  Laboratories,  an oil & gas  services  company,  entered our  portfolio in
mid-2004              because       of                 its                  good

                                        2

financial  quality  rating,  and started doing  especially well according to our
earnings  expectations signal in October 2005. The company posted record results
for the fourth  quarter 2005.  Both of these  examples  illustrate the potential
ability of our financial quality model to predict future earnings strength.  GFI
Group is an example of a profitable Fund investment in the financial sector. The
company,  which provides brokerage services to institutional  clients,  strongly
outperformed its peers during the annual period, maintaining attractive earnings
growth prospects  through February 2006 and advancing more than 80% over the six
months ended February 28, 2006. Of course, not every investment works out and we
cannot always avoid companies that experience  revenue and earnings  shortfalls,
events that can have a severely  negative  impact on stock prices.  For example,
the Fund's  investment in Skyworks  Solutions was  profitable for the six months
ended August 2005, but faltered when the company  warned of a revenue  shortfall
in its fiscal fourth  quarter.  As of the end of February  2006, we continued to
hold this stock in the Fund, as it maintained  favorable  financial  quality and
relative valuation rankings.

INVESTMENT POSITIONING.  We strive to maintain Fund characteristics in line with
the  benchmark.  Note that small  deviations  from  benchmark  reflected in both
sector  exposures and the fundamental  characteristics  of the Fund arise purely
from the  bottom-up  stock  selection  process and do not reflect any attempt to
time the overall market, style preferences, or sector rotation. As of the end of
February  2006,  our  median  market  capitalization  was  below  benchmark.  By
continuing to keep the size of the Fund controlled,  we benefit from the ability
to maintain exposure to the smaller  companies within the small cap market.  The
Fund  maintains a bias to companies  with  modestly  higher  long-term  earnings
growth  rates  and   price-to-earnings   ratios;   however,  the  Fund's  median
price-to-sales  ratio  continues to be lower than the benchmark,  reflecting its
primacy in our relative valuation model.

PROGRESS AT BOGLE INVESTMENT MANAGEMENT.  L.P. Our team has not changed over the
last six months, remaining at twelve full-time professionals,  five dedicated to
portfolio   management  and  research  and  seven  focused  on  client  service,
compliance, and operations. At the end of February 2006, assets in the Fund were
just over $367 million and the Fund remains closed to new investors.  After more
than six years in our original  office space,  we recently took  advantage of an
opportunity to move to a slightly larger office space, not far from where we set
up  shop  in  late-1999.   Please   continue  to  send  all   investment-related
correspondence  to our transfer agent,  PFPC; but if you wish to reach us in the
investment  management  office,  please make note of our new address as shown on
the back cover of this report. Our phone numbers remain the same.

As a reminder,  information  about the Fund,  including  historical NAVs, sector
allocation, fundamental characteristics,  and top ten holdings, can be viewed on
our website, WWW.BOGLEFUNDS.COM. The NAVs are updated daily while the other Fund
information is updated quarterly.

The  Russell  2000(R) is an index of stocks  1001  through  3000 in the  Russell
3000(R) Index, as ranked by total market capitalization.  The index is unmanaged
and not available for direct  investment.  Unlike a mutual fund, the performance
of an index  assumes  no  taxes,  transaction  costs,  management  fees or other
expenses.

The fund is actively  managed on a daily  basis,  and the  securities  mentioned
herein  may not be  representative  of  current  or  future  composition  of the
portfolio.  For more specific  information about fund holdings,  please refer to
the Portfolio of Investments section in this report.

Investing in small companies can involve more  volatility,  less liquidity,  and
less publicly available information than investing in large companies.

                             FUND EXPENSE EXAMPLES
                                   (UNAUDITED)

As a  shareholder  of the Fund,  you incur two types of costs:  (1)  transaction
costs and (2) ongoing costs,  including management fees,  shareholder  servicing
fees and other Fund expenses. These examples are intended to help you understand
your ongoing  costs (in  dollars) of investing in the Fund and to compare  these
costs with the ongoing costs of investing in other mutual funds.

These examples are based on an investment of $1,000 invested at the beginning of
the six-month  period from September 1, 2005 through February 28, 2006, and held
for the entire period.

ACTUAL EXPENSES

The first line of the  accompanying  tables  provides  information  about actual
account values and actual  expenses.  You may use the  information in this line,
together  with the amount you  invested,  to estimate the expenses that you paid
over the period.  Simply divide your account  value by $1,000 (for  example,  an
$8,600  account value divided by $1,000 = 8.6),  then multiply the result by the
number in the first  line  under the  heading  entitled  "Expenses  Paid  During
Period" to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The  second  line  of  the  accompanying   tables  provides   information  about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense  ratio and an  assumed  rate of return of 5% per year  before  expenses,
which is not the Fund's  actual  return.  The  hypothetical  account  values and
expenses  may not be used to  estimate  the  actual  ending  account  balance or
expenses you paid for the period.  You may use this  information  to compare the
ongoing costs of investing in the Fund and other funds.  To do so, compare these
5% hypothetical  examples with the 5%  hypothetical  examples that appear in the
shareholder reports of other funds.

Please  note that the  expenses  shown in the  accompanying  tables are meant to
highlight  your ongoing costs only and do not reflect any  transactional  costs,
such as redemption fees.  Therefore,  the second line of the accompanying tables
is useful in comparing  ongoing costs only,  and will not help you determine the
relative  total  costs  of  owning  different  funds.  In  addition,   if  these
transactional costs were included, your costs would have been higher.

*Expenses are equal to the Fund's annualized expense ratio of 1.25% for the
 Institutional Class and 1.35% for the Investor Class, which includes waived
 fees or reimbursed expenses, multiplied by the average account value over the
 period, multiplied by the number of days (181) in the most recent fiscal
 half-year, then divided by 365 to reflect the one-half year period. The Fund's
 ending account values on the first line in each table are based on the actual
 total return for each class of 19.39% for the Institutional Class and 19.34%
 for the Investor Class.

1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     The RBB Fund, Inc. ("RBB" or "Company") was incorporated  under the laws of
the  State of  Maryland  on  February  29,  1988  and is  registered  under  the
Investment Company Act of 1940, as amended, (the "Investment Company Act") as an
open-end  management  investment  company.  RBB is a "series  fund,"  which is a
mutual fund divided into  separate  portfolios.  Each  portfolio is treated as a
separate  entity for certain  matters under the Investment  Company Act, and for
other  purposes,  and a  shareholder  of one  portfolio  is not  deemed  to be a
shareholder  of  any  other  portfolio.  Currently,  RBB  has  seventeen  active
investment  portfolios,  including  the Bogle  Investment  Management  Small Cap
Growth Fund (the "Fund"),  which commenced  investment  operations on October 1,
1999.  As  of  the  date  hereof,   the  Fund  offers  two  classes  of  shares,
Institutional Class and Investor Class.

     RBB has  authorized  capital of thirty  billion  shares of common  stock of
which 26.473 billion are currently classified into one hundred and three classes
of common stock.  Each class represents an interest in an active or inactive RBB
investment  portfolio.  The active classes have been grouped into seven separate
"families," six of which have begun investment operations.

     PORTFOLIO  VALUATION  -- The Fund's net asset value  ("NAV") is  calculated
once daily at the close of regular  trading  hours on the NYSE  (generally  4:00
p.m. Eastern time) on each day the NYSE is open. Securities held by the Fund are
valued using the closing  price or the last sale price on a national  securities
exchange  or  on  the  National  Association  of  Securities  Dealers  Automatic
Quotation System  ("NASDAQ")  market system where they are primarily  traded. If
there  were  no  sales  on  that  day or the  securities  are  traded  on  other
over-the-counter  markets,  the mean of the last bid and ask prices prior to the
market close are used. Short-term debt securities having a remaining maturity of
60 days or less are amortized to maturity based on their cost.  Debt  securities
having a  remaining  maturity  of  greater  than 60 days are  valued at the mean
between the bid and ask prices.  Investments  in mutual  funds are valued at the
funds closing NAV. With the approval of the  Company's  Board of Directors,  the
Fund may use a pricing service,  bank or broker-dealer  experienced in providing
valuations to value the Fund's securities.  If market quotations are unavailable
or  deemed  unreliable,  securities  will  be  valued  by the  Fund's  Valuation
Committee following procedures adopted by the Board of Directors.

     USE OF ESTIMATES -- The  preparation of financial  statements in conformity
with accounting  principles  generally  accepted in the United States of America
requires  management to make estimates and assumptions  that affect the reported
amounts  of assets and  liabilities  and  disclosure  of  contingent  assets and
liabilities at the date of the financial  statements and the reported amounts of
revenues and expenses during the period.  Actual results could differ from those
estimates.

     REPURCHASE  AGREEMENTS -- The Fund may purchase  securities  from financial
institutions  subject  to  the  seller's  agreement  to  repurchase  them  at an
agreed-upon time and price ("repurchase agreements"). The financial institutions
with  whom  the  Fund  enters   into   repurchase   agreements   are  banks  and
broker-dealers that Bogle Investment Management, L.P. (the "Adviser" or "Bogle")
considers  creditworthy.  The  seller,  under a  repurchase  agreement,  will be
required to maintain the value of the securities as collateral,  subject to  the

                                       16

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                  (UNAUDITED)

agreement  at not less than the  repurchase  price plus  accrued  interest.  The
Adviser  marks to market daily the value of the  collateral,  and, if necessary,
requires  the  seller  to  deposit  additional  collateral  by the  next  day of
business,  to  ensure  that the  value is not less  than the  repurchase  price.
Default  by or  bankruptcy  of the  seller  would,  however,  expose the Fund to
possible loss because of adverse market action or delays in connection  with the
disposition of the underlying securities.  For the six months ended February 28,
2006, the Fund did not enter into any repurchase agreements.

     INVESTMENT TRANSACTIONS, INVESTMENT INCOME AND EXPENSES -- The Fund records
security  transactions  based on trade  date.  The cost of  investments  sold is
determined  by use of the  specific  identification  method  for both  financial
reporting and income tax purposes in  determining  realized  gains and losses on
investments. Interest income is accrued when earned. Dividend income is recorded
on the  ex-dividend  date.  The Fund's net  investment  income (other than class
specific  shareholder  servicing  fees) and  unrealized  and realized  gains and
losses  are  allocated  daily to each class of shares  based  upon the  relative
proportion  of net assets of each class at the  beginning  of the day.  Expenses
incurred on behalf of a specific class, fund or fund family are charged directly
to the  class,  fund or fund  family (in  proportion  to net  assets).  Expenses
incurred for all of the RBB families (such as director or professional fees) are
charged to all funds in proportion  to their net assets of the RBB Funds,  or in
such other manner as the Board of Directors  deems fair or  equitable.  Expenses
and fees,  including  investment  advisory and administration  fees, are accrued
daily and taken into account for the purpose of determining  the net asset value
of the Fund.

     DIVIDENDS  AND   DISTRIBUTIONS   TO  SHAREHOLDERS  --  Dividends  from  net
investment  income and  distributions  from net realized  capital gains, if any,
will be declared  and paid at least  annually to  shareholders  and  recorded on
ex-date.  Income  dividends  and capital gain  distributions  are  determined in
accordance  with U.S.  federal  income tax  regulations  which may  differ  from
accounting principles generally accepted in the United States. These differences
include  the  treatment  of  non-taxable   dividends,   expiring   capital  loss
carryforwards, foreign currency gain/loss, and losses deferred due to wash sales
and excise tax regulations. Permanent book and tax basis differences relating to
shareholder distributions will result in reclassifications within the components
of net assets.

     U.S. TAX STATUS -- No provision is made for U.S.  income taxes as it is the
Fund's  intention  to  qualify  for and elect the tax  treatment  applicable  to
regulated  investment  companies under Subchapter M of the Internal Revenue Code
of 1986, as amended,  and make the requisite  distributions  to its shareholders
which will be sufficient to relieve it from U.S. income and excise taxes.

     OTHER  -- In the  normal  course  of  business,  the Fund  may  enter  into
contracts that provide  general  indemnifications.  The Fund's maximum  exposure
under these  arrangements  is  dependent  on claims that may be made against the
Fund in the future,  and,  therefore,  cannot be  estimated;  however,  based on
experience, the risk of material loss for such claims is considered remote.

Fund's average daily net assets, computed daily and payable monthly.

     The  Adviser  contractually  agreed to limit  the  Fund's  total  operating

1.25% of the  average  daily net  assets of the Fund's  Institutional  Class and
1.35%  of the  average  daily  net  assets  of the  Fund's  Investor  Class.  As
necessary,  this  limitation  is  effected  in  waivers  of  advisory  fees  and
reimbursements  of expenses  exceeding  the advisory  fee. The  contractual  fee

As of August 31, 2005, the components of  distributable  earnings on a tax basis
were as follows:

     At August 31, 2005, the Fund had no capital loss carryforwards available to
offset future capital gains.

     Under Federal tax law,  foreign  currency and capital losses realized after
October 31 may be deferred and treated as having  arisen on the first day of the
following  fiscal year. For the year ended August 31, 2005, the Fund incurred no
post-October  capital  losses.  The  differences  between the book and tax basis
components  of  distributable  earnings  relate  principally  to the  timing  of
recognition of income and gains for federal income tax purposes.  Short-term and
foreign currency gains are reported as ordinary income for federal tax purposes.

                                   (UNAUDITED)









           This report is intended for the information of shareholders
                of Senbanc Fund, but it may also be used as sale
             literature when preceded or accompanied by the current

            investment objectives and operating policies of the Fund.




SIX MONTHS ENDED FEBRUARY 28, 2006


TO: SHAREHOLDERS OF SENBANC FUND

The  decline in Senbanc  Fund's net asset value  ("NAV")  reversed in the second
half  of  the   six-month   period  ended   February  28,  2006.   Adjusted  for
distributions, Senbanc's NAV has risen 112% since its inception in 1999, versus
a 71% gain in the  unmanaged  Nasdaq Bank Index.  Five year  annualized  returns
confirm  Senbanc's  relative  strength.  One day before the end of the six-month
period  ended  February  28,  2006,  the Fund's NAV reached  its highest  level,
including  distributions,   since  its  inception  in  1999.

Senbanc Fund has underperformed the Nasdaq Bank Index in the most recent one and
three year periods  because of the Fund's steady  accumulation  of large cap and
money center bank stocks. This shift in emphasis is indicated by the discrepancy
in market  capitalization  between Senbanc Fund, and the Nasdaq Bank Index which
contains few large capitalization bank stocks.

In a larger context,  rising interest rates since March 2004 have been perceived
as a negative by bank stock  investors,  and the band of valuation for all banks
has narrowed without regard to relative merit.

There is now a  confluence  of events  that  should  reward  well run banks:  we
believe that short term  interest  rate rises may be closer to their end than to
their beginning,  and the weight of evidence that the earnings of well-run banks
benefit from changes in interest rates may, in its eighth quarter,  be too great
to be ignored.

We believe that Senbanc Fund is now ideally  placed to take  advantage of a long
overdue reversal in investors' perceptions of bank stocks.

                                                 Yours very truly,

                                                 /s/Alan F. Morel
                                                 Alan F. Morel

Unlike a mutual fund, performance of an index assumes no taxes, transaction
costs, fees, or expenses. The index is unmanaged and is not available for
direct investment.

                                       1


                                  SENBANC FUND



FUND EXPENSE EXAMPLES (UNAUDITED)
As a  shareholder  of the Fund,  you incur two types of costs:  (1)  transaction
costs,  including  sales charges (loads) on purchase  payments;  and (2) ongoing
costs,  including  management  fees;  distribution  (12b-1) fees; and other Fund
expenses. This example is intended to help you understand your ongoing costs (in
dollars) of  investing  in the Fund and to compare  these costs with the ongoing
costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the entire period September 1, 2005 to February 28, 2006.

ACTUAL EXPENSES
The first line of the table below  provides  information  about  actual  account
values and actual expenses.  You may use the information in this line,  together
with the amount you  invested,  to estimate the expenses  that you paid over the
period.  Simply  divide your  account  value by $1,000 (for  example,  an $8,600
account value  divided by $1,000 = 8.6),  then multiply the result by the number
in the first line under the heading  entitled  "Expenses  Paid During Period" to
estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second  line of the table  below  provides  information  about  hypothetical
account  values and  hypothetical  expenses  based on the Fund's actual  expense
ratio and an assumed rate of return of 5% per year before expenses, which is not
the Fund's actual return.  The hypothetical  account values and expenses may not
be used to estimate the actual ending  account  balance or expenses you paid for
the  period.  You may use the  information  to  compare  the  ongoing  costs  of
investing in the Fund and other funds.  To do so,  compare this 5%  hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the  expenses  shown in the table are meant to  highlight  your
ongoing  costs only and do not reflect any  transactional  costs,  such as sales
charges (loads).  Therefore, the second line of the table is useful in comparing
ongoing costs only,  and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

  * Expenses  are  equal  to  the  Fund's  annualized  expense  ratio  of  1.30%
    multiplied by the average  account value over the period,  multiplied by the
    number of days (181) in the most recent  fiscal  half-year,  then divided by
    365 to reflect the one-half year period.  The Fund's ending account value is
    based on the actual total return of 4.58%.

                                  (UNAUDITED)



1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

The RBB Fund, Inc. ("RBB" or "Company") was  incorporated  under the laws of the
State of Maryland on February 29, 1988 and is  registered  under the  Investment
Company Act of 1940, as amended,  (the "Investment  Company Act") as an open-end
management  investment  company.  RBB is a "series fund", which is a mutual fund
divided into separate portfolios. Each portfolio is treated as a separate entity
for certain  matters under the Investment  Company Act, and for other  purposes,
and a  shareholder  of one  portfolio is not deemed to be a  shareholder  of any
other  portfolio.  Currently,  RBB has seventeen active  investment  portfolios,
including the Senbanc Fund(the "Fund").  As of the date hereof,  the Fund offers
one class of shares.

RBB has  authorized  capital of thirty  billion  shares of common stock of which
26.473  billion are currently  classified  into one hundred and three classes of
common  stock.  Each class  represents  an interest in an active or inactive RBB
investment  portfolio.  The active classes have been grouped into seven separate
"families",  six of which have begun investment  operations.

The Fund  commenced  operations  on July 8, 1999, as a separate  portfolio  (the
"Predecessor  Fund") of the Hilliard Lyons Research  Trust.  On August 31, 2005,
all of the assets and  liabilities of the Predecessor  Fund were  transferred to
the Fund,  a  newly-created  portfolio of the Company,  that is  continuing  the
business,  including  carrying forward the financial and performance  history of
the Predecessor Fund.

PORTFOLIO  VALUATION -- The Fund's net asset value  ("NAV") is  calculated  once
daily at the close of regular  trading  hours on the NYSE  (generally  4:00 p.m.
Eastern  time) on each day the  NYSE is  open.  Securities  held by the Fund are
valued using the closing  price or the last sale price on a national  securities
exchange  or  on  the  National  Association  of  Securities  Dealers  Automatic
Quotation System  ("NASDAQ")  market system where they are primarily  traded. If
there  were  no  sales  on  that  day or the  securities  are  traded  on  other
over-the-counter  markets,  the mean of the last bid and ask prices prior to the
market close are used. Short-term debt securities having a remaining maturity of
60 days or less are amortized to maturity based on their cost.  Debt  securities
having a  remaining  maturity  of  greater  than 60 days are  valued at the mean
between the bid and ask prices.  With the  approval  of the  Company's  Board of
Directors, the Fund may use a pricing service, bank or broker-dealer experienced
in providing valuations to value the Fund's securities. If market quotations are
unavailable  or deemed  unreliable,  securities  will be  valued  by the  Fund's
Valuation Committee following procedures adopted by the Board of Directors.

USE OF ESTIMATES -- The  preparation of financial  statements in conformity with
accounting  principles  generally  accepted  in the  United  States  of  America
requires  management to make estimates  and assumptions that affect the reported
amounts  of assets and  liabilities  and  disclosure  of  contingent  assets and
liabilities at the date of the financial  statements and the reported amounts of
revenues and expenses during the period.  Actual results could differ from those
estimates.

INVESTMENT  TRANSACTIONS,  INVESTMENT  INCOME AND  EXPENSES -- The Fund  records
security  transactions  based on trade  date.  The cost of  investments  sold is
determined  by use of the  specific  identification  method  for both  financial
reporting and income tax purposes in  determining  realized  gains and losses on
investments. Interest income is accrued when earned. Dividend income is recorded
on the ex-dividend  date.  Expenses incurred on behalf of a specific class, fund
or fund  family  are  charged  directly  to the class,  fund or fund  family (in
proportion to net assets).  Expenses  incurred for all of the RBB families (such
as

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                FEBRUARY 28, 2006
                                   (UNAUDITED)

director or  professional  fees) are charged to all funds in proportion to their
net assets of the RBB funds,  or in such other  manner as the Board of Directors
deems fair or equitable.  Expenses and fees,  including  investment advisory and
administration fees, are accrued daily and taken into account for the purpose of
determining the net asset value of the Fund.

DIVIDENDS AND  DISTRIBUTIONS  TO  SHAREHOLDERS  -- Dividends from net investment
income and  distributions  from net  realized  capital  gains,  if any,  will be
declared  and paid at least  annually to  shareholders  and recorded on ex-date.
Income  dividends and capital gain  distributions  are  determined in accordance
with U.S.  federal  income  tax  regulations  which may differ  from  accounting
principles  generally accepted in the United States.  These differences  include
the treatment of non-taxable  dividends,  expiring  capital loss  carryforwards,
foreign currency gain/loss, and losses deferred due to wash sales and excise tax
regulations.  Permanent book and tax basis  differences  relating to shareholder
distributions  will result in  reclassifications  within the  components  of net
assets.

U.S.  TAX  STATUS -- No  provision  is made for U.S.  income  taxes as it is the
Fund's  intention  to  qualify  for and elect the tax  treatment  applicable  to
regulated  investment  companies under Subchapter M of the Internal Revenue Code
of 1986, as amended,  and make the requisite  distributions  to its shareholders
which will be sufficient to relieve it from U.S. income and excise taxes.

OTHER -- In the normal  course of  business,  the Fund may enter into  contracts
that provide general  indemnifications.  The Fund's maximum exposure under these
arrangements  is  dependent  on claims that may be made  against the Fund in the
future, and, therefore,  cannot be estimated;  however, based on experience, the
risk of material loss for such claims is considered remote.

2. TRANSACTIONS WITH AFFILIATES AND RELATED PARTIES

5. FEDERAL INCOME TAX INFORMATION
At February 28, 2006, Federal tax cost, aggregate gross unrealized  appreciation
and depreciation of securities held by the Fund were as follows:

        Cost of investments for tax purposes .................   $183,668,965
        Gross tax unrealized appreciation.....................     32,410,118

        Gross tax unrealized depreciation.....................     (3,094,800)
                                                                 ------------
        Net tax unrealized appreciation on investments........   $ 29,315,318
                                                                 ============

At August 31,  2005,  the Fund had no capital  loss  carryforwards  available to
offset future capital gains.

Under  Federal tax law,  foreign  currency  and capital  losses  realized  after
October 31 may be deferred and treated as having  arisen on the first day of the
following  fiscal year. For the year ended August 31, 2005, the Fund incurred no
post-October  capital  losses.  The  differences  between the book and tax basis
components  of  distributable  earnings  relate  principally  to the  timing  of
recognition of income and gains for federal income tax purposes.  Short-term and
foreign currency gains are reported as ordinary income for federal tax purposes.

6. INDUSTRY CONCENTRATION RISK

Since the Fund's investments will be concentrated in the banking industry,  they
will be subject to risks in addition  to those that apply to the general  equity
market.  Events may occur that significantly affect the entire banking industry;
therefore,  the Fund's share value may at times increase or decrease at a faster
rate than the share value of a mutual fund with investments in many industries.
