Cash in corporations can fluctuate.
corporations purchase raw materials in large quantities and sometimes several materials are bought in the same month.
the purchase is not cost for the corporation as the cash is exchanged for raw materials of the same value.
The following months, cash will increase with sales and the cost of materials will come off the value of materials stored in the country.
A sudden drop in profit occurs when the corporations, although production continues, did not sell the product in that month.
Product sales numbers were probably very low.
