*The Adviser contractually agreed beginning as of January 1, 2013, to limit each
Fund's total operating expenses (excluding any extraordinary expenses that may arise
and charges incurred in trading portfolio securities) to its investment management
fees. This contractual obligation continues in effect until April 30, 2017, and
will continue for each succeeding 12 month period thereafter, unless either the
Investment Company gives not less than 30 days' written notice of termination to
the Adviser or the Adviser gives written notice of termination to the Investment
Company within a 45 day calendar period prior to the next May 1.
Beginning in 2009, the Adviser has waived a portion or all of the Money Market Fund's
Management Fee (not to exceed 0.20%), and other expenses of the Fund for which the Adviser
is entitled to reimbursement, to cause the cumulative monthly total investment returns,
net of fees and expenses, to be no less than zero. This waiver is not permanent or
contractual, is at the discretion of the Adviser, and may be revoked in whole or in part at
any time. Upon such revocation, the fund will not be liable for the fees and expenses that
were waived, but the full amount of these fees and expenses will be imposed from the time
of revocation forward.
