Supplement to the Statement of Additional Information Dated March 26, 2014

Statement of Additional Information Text Changes

In the Investment Advisory Services section, the following is added under “1. Other Accounts Managed” on
page B-36:

Stuart Spangler co-manages a portion of Vanguard Convertible Securities Fund. As of November 30, 2014, Mr. Spangler
also managed 1 other registered investment company with total assets of $212 million, 2 other pooled investment
vehicles with total assets of $653 million, and 17 other accounts with total assets of $2.4 billion (none of which had
advisory fees based on account performance).

In the same section, the following replaces the second paragraph under “3. Description of Compensation” on
page B-36:

Larry Keele, Portfolio Manager of the Fund, is a Principal of Oaktree and is compensated by virtue of his ownership
interest in an Oaktree affiliate. The compensation for Stuart Spangler, Jean-Paul Nedelec, and Abe Ofer, Managing
Directors for Oaktree and Portfolio Managers for the Fund, generally consists of a base salary, participation in the firm-
wide bonus pool, and distributions under Oaktree’s equity plan. Equity participation vests over a multi-year period. At
Oaktree, salaries are capped so that a significant portion of an individual’s compensation is derived from bonuses, which
are a function of the firm’s profitability and the individual’s responsibilities and performance, and equity participation for
the most senior employees. The Portfolio Managers’ compensation is not specifically dependent on the performance of
the Convertible Securities Fund, on an absolute basis or relative to the Fund’s specific benchmark. They are not
compensated based on the growth of the Fund’s, or any other client’s assets except to the extent that such growth
contributes to the firm’s overall asset growth, which in turn contributes to the firm’s overall profitability. They do not
receive a percentage of the revenue earned on any client portfolios, and their compensation is not increased or
decreased specifically as a result of any performance fee that may be earned by Oaktree with respect to the funds or
accounts they manage.

In the same section, the following is added under “4. Ownership of Securities” on page B-36:

As of November 30, 2014, Mr. Spangler did not own any shares of the Fund.
