100% to the Investors pro rata based on

Контекст:

(a) Subject to the remaining provisions of this Clause 10.1, all Net Distributable Cash shall be used first to pay the General Partner's Share and shall thereafter, unless recycled in accordance with Clause 10.7 (Re-investment Cash), be distributed in the following order of priority:
(i) first, 100% to the Investors pro rata based on their Percentage Interests, until each Investor has received an aggregate amount equal to its Loan Contributions, whether or not repaid;

imho "pro rata based on their Percentage Interests" = на пропорциональной основе с учетом их процентных ставок

Почему русская фраза не может звучать просто - "пропорционально их вкладам/ставкам/доле/чему-то"?
