Cash Distributions	Cash Distributions AB is required to distribute all of its Available Cash Flow, as defined in the AB Partnership Agreement, to its Unitholders and to the General Partner. Available Cash Flow can be summarized as the cash flow received by AB from operations minus such amounts as the General Partner determines, in its sole discretion, should be retained by AB 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. Typically, Available Cash Flow has been the adjusted diluted net income per unit for the quarter multiplied by the number of general and limited partnership interests at the end of the quarter. In future periods, management anticipates that Available Cash Flow will be based on adjusted diluted net income per unit, unless management determines that one or more non-GAAP adjustments that are made for adjusted net income should not be made with respect to the Available Cash Flow calculation. On April 28, 2016, the General Partner declared a distribution of $0.45 per AB Unit, representing a distribution of Available Cash Flow for the three months ended March 31, 2016. The General Partner, as a result of its 1% general partnership interest, is entitled to receive 1% of each distribution. The distribution is payable on May 19, 2016 to holders of record on May 9, 2016.

Cash Distributions

AB is required to distribute all of its Available Cash Flow, as defined in the AB Partnership Agreement, to its Unitholders and to the General Partner. Available Cash Flow can be summarized as the cash flow received by AB from operations minus such amounts as the General Partner determines, in its sole discretion, should be retained by AB 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.

Typically, Available Cash Flow has been the adjusted diluted net income per unit for the quarter multiplied by the number of general and limited partnership interests at the end of the quarter. In future periods, management anticipates that Available Cash Flow will be based on adjusted diluted net income per unit, unless management determines that one or more non-GAAP adjustments that are made for adjusted net income should not be made with respect to the Available Cash Flow calculation.

On April 28, 2016, the General Partner declared a distribution of $0.45 per AB Unit, representing a distribution of Available Cash Flow for the three months ended March 31, 2016. The General Partner, as a result of its 1% general partnership interest, is entitled to receive 1% of each distribution. The distribution is payable on May 19, 2016 to holders of record on May 9, 2016.
