Loan delinquency and loan default are used interchangeably in the Philippines. Under Republic Act No. (R.A.) 10870, otherwise known as the Philippine Credit Card Industry Regulation Law, default or delinquency refers to the nonpayment or payment of an amount less than the amount required to be paid for at least three billing cycles. The law also says that the billing cycle is the period between billing, which comprises at least 15 days.
