Quote from ScalperJoe:
Based on Don's comment that it's end of year, then your scenario would be as follows:
Scene 1: 1st month. If you made 10k, then you would have a liability to Bright for 2k, which could be added/deleted based on your following month's p&l. So Bright could also "lose" its cut of 20% if you lost any gains such that the end of year net was zero.
Scene 2: 1st month. If you make a LOSS of 10k, then my understanding of the model is that your capital contribution is simply reduced by 50% of your original 20k deposit, thus you have 10k left in your balance. No loss to Bright.
The question is: what happens if you want Bright to cut a check if you carry a net monthly gain, would they pay out 80% and book its own gains of 20% intrayear?
