    - (A) such investment shall be treated as 2 separate investments, consisting of—
      - (i) one investment that only includes amounts to which the election under [subsection (a)](#a) applies, and
      - (ii) a separate investment consisting of other amounts, and
    - (B) subsections [(a)](#a), [(b)](#b), and [(c)](#c) shall only apply to the investment described in [subparagraph (A)(i)](#e-1-A-i).

      - (i) the amount equal to 90 percent of its aggregate assets, over
      - (ii) the aggregate amount of qualified opportunity zone [property](/usc/26/317.md?p=a) held by the [fund](/usc/26/851.md?p=g-2), multiplied by
