Our debt has been increasing because our cash profit on operations (revenues less wages and other operating expenses), subtract payments owed to other clubs for previous transfers, interest expense, and investment in new players, the club is in cash deficit. It then borrows using its bank credit lines to make up this deficit. Typically bank loans are stringent with high amortization payments. Bonds on the other hand are more flexible, and Juve can wait 5 years before making any payments.
Whether it is good or not?
Well, it depends. interest payments on bonds are generally higher, but as I said, they are more flexible, and usually don't have a direct claim on company assets. Also, no amortization payments are due, and instead the whole amount owed can be paid or refinanced in 5 years. Also it depends on what the use of proceeds are. If it is to refinance bank debt it is neutral, and if it is to buy players well, good for us, but obviously it needs to also manage debt levels.
