AutoProtect Coffers (SimCity 4)

The auto protection modd uses the news event of simcity to detect if your projected funds in 6 months will be less than -100,000, which can cause you to be kicked out of the game.

There are two protection types, one is small funds which reacts only when your funds dips below 0 and will raise your coffers (6 months x expenses) to the nearest 10,000 simoleons. The second is large fund protection which detects that your funds can go negative suddenly (expenses > 100,000/month) and attempts to protect you by allocating a 12 month funding.
