2.1.Issuing bonds:

Companies issue bonds to finance operations. Most companies can borrow from banks, but view direct borrowing from a bank as more restrictive and expensive than selling debt on the open market through a bond issue.

The costs involved in borrowing money directly from a bank are prohibitive to a number of companies. In the world of corporate finance, many chief financial officers (CFOs) view banks as lenders of last resort because of the restrictive debt covenants that banks place on direct corporate loans. Covenants are rules placed on debt that are designed to stabilize corporate performance and reduce the risk to which a bank is exposed when it gives a large loan to a company. In other words, restrictive covenants protect the bank's interests; they're written by securities lawyers and are based on what analysts have determined to be risk to that company’s performance.

Simply put, banks place greater restrictions on what a company can do with a loan and are more concerned about debt repayment than bondholders. Bond markets tend to be more forgiving than banks and are often seen as being easier to deal with. As a result, companies are more likely to finance operations by issuing bonds than by borrowing from a bank.
