How does an interest free loan become a contribution
The have 16 months before payments start and that is worth quite a bit, but it is not exactly an investment in the company in the usual sense.
It is worth $240k through May 2025 and then another $520 k over the 5 years of the payoff, assuming the interest would be 6.5% rather than zero. It is probably worth double that to RHC because they could not borrow more money right now at any interest rate.
