Dear Ms. Marquigny:

On December 30, 2009, we filed the above-referenced registration statements on Form N-4. At the Staff’s request, this letter is to help identify similar sections of the prospectuses in those filings. The filings are substantially similar. For your review, I would suggest using ONcore Premier II (333-164070) and NScore Premier II (333-164071) as your templates for Ohio National Variable Account A and National Security Variable Account N, respectively.

The attached charts set forth the basic features of the products and which riders are available. The riders included in the filings are the same as riders included in Ohio National Variable Account A’s 485(a) post-effective amendment filings filed on December 3, 2009 (one of which was ONcore Premier, 333-43515) (the “December 3, 2009 filings”), except for the GMIB Plus with Annual Reset included in the National Security Variable Account N filings which is the same as the GMIB Plus with Annual Reset (2009) in National Security Variable Account N’s existing filings (one of which is NScore Premier, 333-125856). The GMIB Plus with Annual Reset in the above-

referenced ONcore filings is the same as the GMIB Plus with Annual Reset (2009) version included in the December 3, 2009 filings. The ARDBR in the above-referenced filings is the same as the ARBDR (2009) version in the December 3, 2009 filings. The GMDBR80 Plus and GMDBR85 Plus in the above-referenced filings are the same as the 5% GMDBR80 Plus and 5% GMDBR85 Plus versions in the December 3, 2009 filings.

Should you have any questions or comments, please contact me at (513) 794-6278.

Sincerely,
 

/s/ Kimberly A. Plante
