"The SPSPA calls for 10% dividends IN PERPETUITY, that means forever."
Steelhead9,
This is not correct. Under original SPSPA, SPS liquidation preference changes based on draws and paybacks. Under original SPSPA, SPS is completely redeemable.
The correct statement would be "NWS calls for 100% of positive networth IN PERPETUITY, that means forever."
