                                EXECUTIVE SUMMARY

o     The unitary or cluster board structure,  in which directors oversee all or
      many of the  funds in a  complex,  is  prevalent  in the  industry  and is
      consistent with good governance.

o     Neither  Congress nor the  Securities and Exchange  Commission  have found
      that  imposing an  arbitrary  limit on the number of funds a director  may
      oversee would be in the best interests of  shareholders.  Rather,  the SEC
      has required that boards evaluate their performance in this regard as part
      of an annual self-assessment.

o     Mutual funds within a fund family  share the same  investment  adviser and
      other key service providers and, as a result, significant efficiencies are
      realized  when a single or limited  number of boards  oversees  all of the
      funds.

o     Independent  directors  control who serves as an independent  director and
      the amount of compensation  for each director.  Control of these processes
      by  independent  directors  is a  critical  factor  in  assuring  director
      independence.

o     Oversight of significant assets enhances a board's knowledge and expertise
      and its ability to influence  fund  management  and key service  providers
      and,  as a result,  enhances  the  board's  effectiveness  in serving  the
      interests of shareholders.

o     The tasks of a fund director involve a common regulatory structure, common
      personnel  and  service  providers  and  oversight   mechanisms  that  are
      complex-wide.  These  tasks  contrast  significantly  with  the  role of a
      corporate  director  that, in many cases,  involves  oversight of multiple
      product  lines,  several  business  units,  numerous  business  plans  and
      management teams, and diverse regulatory structures and compliance issues.

o     Mutual fund boards have  developed a number of techniques  and  strategies
      that address the  challenges  inherent in the oversight of multiple  funds
      and that enable directors to meet their responsibilities to shareholders.

o     Limiting  the  number  of  funds  a  director  may  oversee  is  not  only
      inefficient, it would result in significant additional management, service
      provider and director costs to shareholders.

o     Board annual assessments provide an opportunity for boards to periodically
      evaluate their ability to continue to provide appropriate oversight to the
      number  of funds  for which  they are  responsible.  A board can take into
      account  a  number  of  relevant  factors,  including  the  types of funds
      involved, the support the board receives and the strategies the board uses
      to manage its workload.
