Item 4. Ownership

The securities reported herein 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 this Item 4. When an investment management contract (including a sub‑advisory

agreement) delegates to an Investment Management Subsidiary investment discretion or

voting power over the securities held in the investment advisory accounts that are subject

to that agreement, FRI treats the Investment Management Subsidiary as having sole

investment discretion or voting authority, as the case may be, unless the agreement

specifies otherwise. Accordingly, each Investment Management Subsidiary reports on

Schedule 13G that it has sole investment discretion and voting authority over the

securities covered by any such investment management agreement, unless otherwise noted in

this Item 4. As a result, for purposes of Rule 13d‑3 under the Act, the Investment

Management Subsidiaries listed in this Item 4 may be deemed to be the beneficial owners of

the securities reported in this Schedule 13G.

Beneficial ownership by Investment Management Subsidiaries and other FRI affiliates 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”) and Franklin Advisory Services, LLC (“FAS”), each 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 and FAS are collectively, “FRI

affiliates”). Furthermore, internal policies and procedures of FMA, FAS and FRI establish

informational barriers that prevent the flow between FMA and FAS, on the one hand, and the

FRI affiliates, on the other hand, of information that relates to the voting and

investment powers over the securities owned by their respective management clients.

Consequently, FMA and FAS report the securities over which they hold investment and voting

power separately from the FRI affiliates for purposes of Section 13 of the Act.

CUSIP NO. 87166L100 13G Page 7 of 13

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 such

securities. In addition, the filing of this Schedule 13G on behalf of the Principal

Shareholders, FRI and the 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 reported in this Schedule 13G.

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.

Item 5. Ownership of Five Percent or Less of a Class

If this statement is being filed to report the fact that as of the date hereof

the reporting person has ceased to be the beneficial owner of more than five

percent of the class of securities, check the following [X].

Item 6. Ownership of More than Five Percent on Behalf of Another Person

The clients of the Investment Management Subsidiaries, including investment

companies registered under the Investment Company Act of 1940 and other

managed accounts, have the right to receive or power to direct the receipt of

dividends from, and the proceeds from the sale of, the securities reported

herein.
