Using Cardinal Ape's excellent work and a current game, I pulled together a cash flow chart for Carthage in the 2nd Punic War.
Please test and offer suggestions to this work; I'll edit in the corrections.
Warning - stop reading at this point if you do not want knowledge of the event before the event.

Comments:
Trade can be: Exceptional 10% chance, Normal, or Poor 10% chance.
Merchants combined with a trade post with give $25 after six turns; the trade post must be replaced.
Requisitions may coerce $50 per area if successful; whether it works or not, loyalty in the area will drop by 10%.
Enslave & plunder for $100 in regions that are not strongly loyal; use requisitions to lower loyalty to this point.
“The More Money” option will allow either faction to exchange 5EP, 2NM, and 25VP for 200$ and a 1% inflation increase; the inflation total is hidden but the % increase does happen.
“Selling Prisoners into Slavery” option if either faction has 5,000 prisoners they will receive an option to sell slaves for $200. If one has enough captured prisoners on hand, this event has a 33% chance every turn to become available again.
Take Leptis Magna and Carthage will lose $200 a year from Caravan trade.
The Carthaginians must build a transport unit and place it in the Mare Hispanicum Commercius area to earn $200 from the Hispania silver mines shipment.
