AGIC is an investment adviser registered under Section 203 of the Investment Advisers Act of 1940, as amended, and is an indirectly wholly-owned subsidiary of Allianz Asset Management of America L.P. (“AAM LP”).

The securities reported herein are held by investment advisory clients or discretionary accounts of which AGIC is the investment adviser. Investment advisory contracts grant to AGIC voting and/or investment power over the securities held by its clients or in accounts that it manages. As a result, AGIC may be deemed to beneficially own the securities held by its clients or accounts within the meaning of Rule 13d-3 under the Act.

In conformity with the guidelines articulated by the SEC staff in Release No. 34-39538 (January 12, 1998) relating to organizations in which related entities exercise voting and investment powers over the securities being reported independently from each other, this filing does not reflect securities beneficially owned by affiliates of AAM LP other than AGIC. The voting and investment powers held by AGIC are exercised independently from AAM LP’s other affiliates, other than AGIC’s wholly-owned subsidiaries, NFJ Investment Group LLC (“NFJ”) and Allianz Global Investors Capital Limited (“AGICL”), each an investment adviser that does not advise accounts that hold, and does not otherwise beneficially own, any of the securities reported on this Schedule 13G. Internal policies and procedures of AGIC, NFJ and AGICL establish informational barriers that prevent the flow between them and the rest of AAM LP’s affiliates of information that relates to the voting and investment powers over the securities held in the accounts that AGIC, NFJ and AGICL manage. Consequently, AGIC, NFJ and AGICL report the securities over which they hold investment and voting power separately from AAM LP and its other affiliates for purposes of Section 13 of the Act.

AGIC believes that none of AGIC, NFJ, AGICL, AAM LP or any of AAM LP’s other affiliates constitute 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 reported herein held by any of them or by any persons or entities for whom or for which AGIC, NFJ or such other affiliates provide investment management services. AGIC also disclaims beneficial ownership of these securities except to the extent of its pecuniary interest therein.

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  ¨.

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

       Each client of AGIC has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of the securities reported herein. No one client holds more than five percent of such securities.

Item 7 Identification and Classification of the Subsidiary Which Acquired the Security Being Reported on By the Parent Holding Company.

       Not Applicable.

Item 8 Identification and Classification of Members of the Group.

       Not Applicable.

Item 9 Notice of Dissolution of Group.

       Not Applicable.

Item 10 Certification.

By signing below I certify that, to the best of my knowledge and belief, the securities referred to above were acquired and are held in the ordinary course of business and were not acquired and are not held for the purpose of or with the effect of changing or influencing the control of the issuer of the securities and were not acquired and are not held in connection with or as a participant in any transaction having that purpose or effect.

SIGNATURE

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
