As uninteresting as it is...
Here's the details of the de Colo trade as they are currently reported.
Raptors trade Austin Daye ($947,907 this year, $250k guaranteed next year)
Spurs trade Nando de Colo ($1,463,000; RFA this summer)
There you have it. Fits within the 150% + 100k limitation for non-tax teams.
