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.

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 of

 

them 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 the Investment Management Subsidiaries provide investment

 

management services.
