AB Holding is required to distribute all of its Available Cash Flow, as defined in the Amended and Restated Agreement of Limited Partnership of AB Holding (“AB Holding Partnership Agreement”), to its Unitholders pro rata in accordance with their percentage interests in AB Holding. Available Cash Flow is defined as the cash distributions AB Holding receives from AB minus such amounts as the General Partner determines, in its sole discretion, should be retained by AB Holding for use in its business or plus such amounts as the General Partner determines, in its sole discretion, should be released from previously retained cash flow.

Available Cash Flow typically is the adjusted diluted net income per unit for the quarter multiplied by the number of units outstanding at the end of the quarter. Management anticipates that Available Cash Flow will continue to be based on adjusted diluted net income per unit, unless management determines, with the concurrence of the Board of Directors, that one or more adjustments that are made for adjusted net income should not be made with respect to the Available Cash Flow calculation.

On October 25, 2017, the General Partner declared a distribution of $0.51 per unit, representing a distribution of Available Cash Flow for the three months ended September 30, 2017. Each general partnership unit in AB Holding is entitled to receive distributions equal to those received by each AB Holding Unit.
