Arrearage
An amount on a loan, cumulative preferred stock, or any credit instrument that is overdue.
Also referred to as "Arrears."
Investopedia Commentary
In the case of a preferred dividend, if the dividend is not paid for any reason, it cumulates, meaning, in the future, arrearages must be paid before any dividend can be paid on common stock.
