Item 4.

Ownership

The securities reported herein (the “Securities”) are beneficially owned by one or

more open- or closed-end investment companies or other managed accounts that are

investment management clients of investment managers that are direct and indirect

subsidiaries (each, an “Investment Management Subsidiary” and, collectively, the

“Investment Management Subsidiaries”) of Franklin Resources, Inc. (“FRI”), including

the Investment Management Subsidiaries listed in Item 7. Investment management

contracts grant to the Investment Management Subsidiaries all investment and/or

voting power over the securities owned by such investment management clients, unless

otherwise noted in this Item 4. Therefore, for purposes of Rule 13d-3 under the Act,

the Investment Management Subsidiaries may be deemed to be the beneficial owners of

the Securities.

Beneficial ownership by investment management subsidiaries and other affiliates of

FRI is being reported in conformity with the guidelines articulated by the SEC staff

in Release No. 34-39538 (January 12, 1998) relating to organizations, such as FRI,

where related entities exercise voting and investment powers over the securities

being reported independently from each other. The voting and investment powers held

by Franklin Mutual Advisers, LLC (“FMA”), an indirect wholly-owned Investment

Management Subsidiary, are exercised independently from FRI and from all other

Investment Management Subsidiaries (FRI, its affiliates and the Investment Management

Subsidiaries other than FMA are collectively, “FRI affiliates”). Furthermore,

internal policies and procedures of FMA and FRI establish informational barriers that

prevent the flow between FMA and the FRI affiliates of information that relates to

the voting and investment powers over the securities owned by their respective

investment management clients. Consequently, FMA and the FRI affiliates report the

securities over which they hold investment and voting power separately from each

other for purposes of Section 13 of the Act.

13G

Page 7 of 15

Charles B. Johnson and Rupert H. Johnson, Jr. (the “Principal Shareholders”) each own

in excess of 10% of the outstanding common stock of FRI and are the principal

stockholders of FRI. FRI and the Principal Shareholders may be deemed to be, for

purposes of Rule 13d-3 under the Act, the beneficial owners of securities held by

persons and entities for whom or for which FRI subsidiaries provide investment

management services. The number of shares that may be deemed to be beneficially

owned and the percentage of the class of which such shares are a part are reported in

Items 9 and 11 of the cover pages for FRI and each of the Principal Shareholders.

FRI, the Principal Shareholders and each of the Investment Management Subsidiaries

disclaim any pecuniary interest in any of the Securities. In addition, the filing of

this Schedule 13G on behalf of the Principal Shareholders, FRI and FRI affiliates, as

applicable, should not be construed as an admission that any of them is, and each

disclaims that it is, the beneficial owner, as defined in Rule 13d-3, of any of the

Securities.

FRI, the Principal Shareholders, and each of the Investment Management Subsidiaries

believe that they are not a “group” within the meaning of Rule 13d-5 under the Act

and that they are not otherwise required to attribute to each other the beneficial

ownership of the Securities held by any of them or by any persons or entities for

whom or for which FRI subsidiaries provide investment management services.

securities referred to above were acquired and are held in the ordinary course of

This report shall not be construed as an admission by the persons filing the report

that they are the beneficial owner of any securities covered by this report.
