To put in in very practical terms, the private capital (and goods and other inputs, for that matter) shown at the top of the game screen when you press END TURN is all that is available to be used for production during turn processing.
If factories or other industries are missing inputs, they shut down, with one exception: if there is not enough private capital available, private capital is added (think of it as printing money) to make up the difference in needed working capital and the result is price inflation.
International sales and domestic sales come later in the turn order and replenish private capital (purchases from abroad use up private capital).
So check F4's line 2 for the private capital reduction and do the math, or just leave a private capital cushion.
The same concept applies to military maintenance - if you don't have enough cash or good left at the end of the turn for both production and maintaining troops, they will suffer.
