Item 4: Ownership

The securities reported on herein are beneficially owned by one or more open-end investment companies or other managed accounts which are advised or sub-advised by Ivy Investment Management Company (“IICO”), an investment advisory subsidiary of Waddell & Reed Financial, Inc. (“WDR”) or Waddell & Reed Investment Management Company (“WRIMCO”), an investment advisory subsidiary of Waddell & Reed, Inc. (“WRI”). WRI is a broker-dealer and underwriting subsidiary of Waddell & Reed Financial Services, Inc., a parent holding company (“WRFSI”). In turn, WRFSI is a subsidiary of WDR, a publicly traded company. The investment advisory contracts grant IICO and WRIMCO all investment and/or voting power over securities owned by such advisory clients. The investment sub-advisory contracts grant IICO and WRIMCO investment power over securities owned by such sub-advisory clients and, in most cases, voting power. Any investment restriction of a sub-advisory contract does not restrict investment discretion or power in a material manner. Therefore, IICO and/or WRIMCO may be deemed the beneficial owner of the securities covered by this statement under Rule 13d-3 of the Securities Exchange Act of 1934 (the “1934 Act”).

IICO, WRIMCO, WRI, WRFSI and WDR are of the view that they are not acting as a “group” for purposes of Section 13(d) under the 1934 Act. Indirect “beneficial ownership” is attributed to the respective parent companies solely because of the parent companies’ control relationship to WRIMCO and IICO.

(a)	Amount beneficially owned: 5,401,474

(b)	Percent of class: 6.7

(c)	Number of shares as to which the person has:

	(i)	Sole voting power to vote or to direct the vote:

		WDR: 5,401,474 (indirect)
		WRFSI: 4,520,225 (indirect)
		WRI: 4,520,225 (indirect)
		WRIMCO: 4,520,225 (direct)
		IICO: 881,249 (direct)

	(ii)	Shared power to vote or to direct the vote: 0

	(iii)	Sole power to dispose or to direct the disposition of:

		WDR: 5,401,474 (indirect)
		WRFSI: 4,520,225 (indirect)
		WRI: 4,520,225 (indirect)
		WRIMCO: 4,520,225 (direct)
		IICO: 881,249 (direct)

(iv)

Shared power to dispose or to direct the disposition of: 0

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 5 percent of the class of securities, check the following: [ ]

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

The clients of IICO and WRIMCO, including investment companies registered under the Investment Company Act of 1940 and other managed accounts, have the right to receive dividends from, as well as the proceeds from the sale of, such securities.

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

See Attached Exhibit 2.

Item 8: Identification and Classification of Members of the Group:

Not Applicable.

Item 9: Notice of Dissolution of Group:

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.
