ONEOK Partners Expected to Be Removed from the Alerian Index Series

DALLAS, June 29, 2017

Special rebalancings are triggered by corporate actions such as mergers, bankruptcies, and liquidations. Pending shareholder approval, OKS will cease to trade due to its merger with ONEOK, Inc. (NYSE: OKE). If approved, the rebalancing will take place one full trading day after the issuance of a press release indicating all needed merger votes have passed.

Notably, the market will be closing early on Monday, July 3, and as a result, the special rebalancing will likely take place after market close on July 5.

The index will be rebalanced in accordance with its existing methodology. Constituent additions to and deletions from the index do not reflect an opinion by Alerian on the investment merits of the respective securities.
