Negative Amortization Limit

What is Negative Amortization Limit?

The negative amortization limit is a provision in certain bonds or other loan contracts that limits the amount of unpaid interest charges that can be added to the loan's principal balance.

Understanding Negative Amortization Limit

A loan negatively amortizes when scheduled payments are made that are less than the interest charge due on the loan at the time. When a payment is made that is less than the interest charge due, deferred interest is created and added to the loan's principal balance, creating negative amortization.

A negative amortization limit states that the principal balance of a loan cannot exceed a certain pre-specified amount, usually designated as a percentage of the original loan balance. Such limits prevent borrowers from getting into situations where they are unable to pay back the loan and are forced to default or declare bankruptcy_ — _and so also protects lenders from default risk.

Negative amortization occurs when the monthly payments on a loan are insufficient to pay the interest accruing on the principal. The additional interest is added to the loan balance, resulting in an ever higher interest expense and loan balance. Hence the term "negative amortization," as the payments are insufficient to amortize the loan balance.

In the case of a negatively amortized mortgage, the homeowner in effect is borrowing more money each month to cover the interest on the loan. Until the loan starts to amortize, there isn't a principal part of the monthly payment, which means that the mortgage balance does not decrease.

Often, these types of loans will have a limit on the amount of negative amortization that can accrue on the loan_ — _set typically as a percentage of the loan's original size. A negative amortization limit prevents a loan's principal balance from becoming too large, causing excessively large payment increases to pay back the loan by the end of its term. For instance, a negative amortization limit of 15% on a $500,000 loan would specify that the amount of negative amortization would not exceed $75,000.

When a negative amortization limit is reached on a loan, a recasting of the loan's payments is triggered so that a new amortization schedule is established and the loan will be paid off by the end of its term. This may be as simple as negotiating a refinancing of the original loan.
