IMPORTANT NOTICE REGARDING CHANGE IN THE FEES AND EXPENSES OF BARON INTERNATIONAL GROWTH AND BARON GLOBAL ADVANTAGE FUNDS

Effective November 15, 2017, in connection with the lowering of certain fees and expenses of Baron International Growth Fund (the "Fund"), the Prospectus of the Fund is modified as follows:

On page 18 of the Prospectus, the "Annual Fund Operating Expenses" table is deleted in its entirety and replaced with the following:

Annual Fund Operating Expenses

(Expenses that you pay each year as a percentage of the value of your investment)

	Management Fee		Distribution (12b-1) Fee		Other Expenses		Total Annual Fund Operating Expenses		Expense Reimbursements			Total Annual Fund Operating Expenses after Expense Reimbursements2
BARON INTERNATIONAL GROWTH FUND1
Retail Shares		0.88%		0.25%		0.40%		1.53%		(0.33	)%		1.20%
Institutional Shares		0.88%		0.00%		0.36%		1.24%		(0.29	)%		0.95%
R6 Shares		0.88%		0.00%		0.38%		1.26%		(0.31	)%		0.95%

¹ Based on the fiscal year ended December 31, 2016 (restated to reflect management fee reduction from 1.00% to 0.88% and current expense waivers).

² BAMCO, Inc. ("BAMCO" or the "Adviser") has agreed that for so long as it serves as the Adviser to the Fund, it will reimburse certain expenses of the Fund, limiting net annual operating expenses (expenses such as portfolio transaction costs, interest, dividend and extraordinary expenses are not subject to the operating expense limitation) to 1.20% of average daily net assets of Retail Shares and 0.95% of average daily net assets of Institutional Shares and R6 Shares.

On page 18 of the Prospectus, the "Example" paragraph and table are deleted in their entirety and replaced with the following:
