“It allows the company to pay off their debt over a longer period of time or at a lower interest rate.”
To be clear, you are saying that Trump has, or will, pay off all the debts he had going into the several bankruptcies?
It set up all four companies so they could be sold. He sold all four at a profit.
Buy a distressed company. Restructure it so the mess is cleared up and sell at a profit. That’s how big business works. It allows the company to continue in business. Continue to employee people and keeps them from becoming empty buildings and distress communities more and add greatly to unemployment rolls
Think GM and US government on a smaller scale.
In one case he asked the bank that a friend had dealt with to restructure their loan ( the economy had tanked and the owner a friend of Trumps needed a loan at a better rate). The company was still making money but there was a recession So a bit of cash flow issue
The bank refused. So Trump paid cash for the company paper Restructured it with a different bank with the blessing of judge the first bank got their principle but NONE of the excessive interest they were demanding.
He then waited a while and sold the property at a profit.
Get it?
