Ladies and Gentlemen:

In our recent 485(a) post-effective amendment filings for the above-referenced registration statements, we made several changes to the variable annuity prospectuses. There are essentially two sets of changed prospectuses. Within each set of changed prospectuses, the changes are similar across all the prospectuses. The first set of changed prospectuses is ONcore Value (333-43513) and ONcore Lite (333-52006). The second set of changed prospectuses is all the other 485(a) post-effective amendment filings.

For the first set of changed prospectuses, you can use ONcore Value (333-43513) as a template. The following shows the primary changed sections (with references to the applicable page numbers in the typeset courtesy copies) in the ONcore Value and ONcore Lite prospectuses:

	Product/ SEC File No.
Sections changed	ONcore Value 333-43513	ONcore Lite 333-52006
Glossary	p. 5	p. 5
Fee Table	pp. 6-7	pp. 6-7
Investment Restrictions for Certain Optional Riders	pp. 11-14	pp. 11-14
Optional Asset Allocation Models	pp. 14-16	pp. 14-15
Charges for Optional Benefits	pp. 18-19	pp. 17-19

Optional Guaranteed Minimum Income Benefit Riders	pp. 36-43	37-44
Summary of Optional Living Benefit Riders (new section)	pp. 46-48	47-49

Please note that the sections “Guaranteed Account” and “Ohio National Life Employee Discount” are marked as changed because they have been moved within the prospectuses, not because of any language changes. Also, note that the “Optional Guaranteed Principal Access (“GPA”)” section has been marked as all new because it has been moved within the prospectus. The only change in the GPA section is to reference that the rider is not currently available in the first paragraph. The “Optional Guaranteed Principal Protection (“GPP”)” section is also marked as all new because it has been moved within the prospectus. The only change in the GPP section is a change in the rider charge.

For the second set of changed prospectuses, you can use ONcore Premier (333-43515) as a template. The following shows the primary changed sections (with references to the applicable page numbers in the typeset courtesy copies) in the ONcore Premier and other ONcore prospectuses (other than ONcore Lite and ONcore Value) and all NScore prospectuses:

	Product/ SEC File No.

Please note that the sections “Guaranteed Account,” “Ohio National Life Employee Discount” (in ONcore prospectuses) and “National Security Employee Discount” (in NScore prospectuses) are marked as changed because they have been moved within the prospectuses, not because of any language changes. Also, note that the “Optional Guaranteed Principal Access (“GPA”)” section has been marked as all new because it has been moved within the prospectus. The only change in the GPA section is to reference that the rider is not currently available in the first paragraph. The “Optional Guaranteed Principal Protection (“GPP”)” section is also marked as all new because it has been moved within the prospectus. The only change in the GPP section is a change in the rider charge.

In addition to the above changes, in both sets of changed prospectuses dates, available funds and certain other information have been updated.
