**Explanatory Note** 

Post-Effective Amendment No. 196 ("PEA 196") under the Securities Act of 1933, as amended (the "Securities Act"), relating to the Northern Trust US Equities Index ETF, Northern Trust Developed Ex-US Index ETF, and Northern Trust US Equity ETF (formerly, Northern Trust US Equities ETF), was filed on November 21, 2025 pursuant to paragraph (a)(2) of Rule 485 under the Securities Act, and would have become effective on February 4, 2026.

This Post-Effective Amendment No. 197 ("PEA 197") under the Securities Act is being filed pursuant to paragraph (b)(1)(iii) of Rule 485 under the Securities Act solely for the purpose of delaying the effectiveness of PEA 196 until March 6, 2026. Prior to the effective date of PEA 196 (as delayed by PEA 197 and any further delaying amendments), the Registrant intends to submit a filing making the Northern Trust US Equities Index ETF and Northern Trust Developed Ex-US Index ETF series inactive in the EDGAR system. Accordingly, the only series from PEA 196 that will go effective is the Northern Trust US Equity ETF.

This PEA 197 incorporates by reference the information contained in [Parts A, B and C](http://www.sec.gov/Archives/edgar/data/916620/000119312525291294/d927940d485apos.htm) of PEA 196.
