MasterCard has defined a Zero Interchange Program under MasterCard’s Business Service Arrangement. They will anticipate the need to use the zero interchange logic in the event of an exceptional circumstance that would warrant an immediate adjustment to merchant level fees, such as a natural disaster. To support this program, we will be adding a Zero Interchange Program Flag and will house a Zero Interchange Start Date and a Zero Interchange End Date. These dates will define the period of time for which interchange fees would not be applied to the eligible merchant.
