CUSIP NO. 640079109	 	13G	 	Page 6 of 8 Pages	
 
Each of the entities named in this Item 4 (collectively, the “AGI Advisers”) is an investment adviser registered under Section 203 of the Investment Advisers Act of 1940, as amended, and a directly or indirectly wholly-owned subsidiary of AGI U.S. Holdings, except that Allianz Global Investors Europe GmbH is an affiliate (but not a subsidiary or under control) of AGI U.S. Holdings and is a non-U.S. institution.
The securities reported in this Schedule 13G are held by investment advisory clients or discretionary accounts of which an AGI Adviser is the investment adviser. When an investment management contract (including a sub-advisory agreement) delegates to an AGI Adviser investment discretion or voting power over the securities held in the investment advisory accounts that are subject to that agreement, AGI U.S. Holdings treats the AGI Adviser as having sole investment discretion or voting authority, as the case may be, unless the agreement specifies otherwise. Accordingly, each AGI Adviser reports on Schedule 13G that it has sole investment discretion or voting authority, as the case may be, over the securities covered by any such investment management agreement. As a result, each AGI Adviser may be deemed to beneficially own the securities held by its clients or accounts within the meaning of rule 13d-3 under the Act. Because AGI U.S. Holdings is the parent holding company of the AGI Advisers that are its subsidiaries, it may be deemed to beneficially own the securities held by those AGI Advisers’ clients or accounts.
In accordance with SEC Release No. 34-39538 (January 12, 1998), this Schedule 13G reports the securities beneficially owned, or deemed to be beneficially owned, by certain subsidiaries and affiliates of AGI U.S. Holdings. It does not include securities, if any, beneficially owned by subsidiaries or affiliates of AGI U.S. Holdings whose ownership of securities is disaggregated from that of the AGI Advisers in accordance with that release.
AGI U.S. Holdings and the AGI Advisers believe that they do not 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 in this Schedule 13G held by any of them or by any persons or entities for whom or for which any AGI Adviser provides investment management services. Each of AGI Holdings U.S. and the AGI Advisers also disclaims beneficial ownership of these securities except to the extent of that filer’s 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 an AGI Adviser named in this Schedule 13G 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 .	
	
See Items 3 and 4.	
		
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.
