any funds received will be returned to the sending institution.

accounts for which the institution acts in some other capacity. An
institution's master account(s) and sub-accounts with the Class may be
aggregated for the purpose of the minimum investment requirement. No
minimum is required for subsequent investments in the Portfolio nor are
minimum balances required. Except for those individual participants in
the AMVESCAP International Sharesave Plan, an Account Application must
