On December 21, 2017, Humana Inc. (“Humana”) entered into an accelerated stock repurchase agreement (the “ASR Agreement”) with Bank of America, N.A. (“BofA”) to repurchase $1.0 billion of its common stock as part of the $3.0 billion share repurchase program that Humana announced on December 14, 2017.

Under the ASR Agreement, on December 22, 2017, Humana made a payment of $1.0 billion to BofA from available cash on hand and received an initial delivery of 3,284,342 shares of Humana common stock from BofA. The specific number of shares that Humana ultimately will repurchase pursuant to the ASR Agreement will be based generally on the daily volume-weighted average share price of Humana common stock over the term of the ASR Agreement, less a discount and subject to adjustments pursuant to the terms and conditions of the ASR Agreement. Final settlement under the ASR Agreement is expected to occur in the first quarter of 2018. The ASR Agreement contains provisions customary for agreements of this type, including provisions for adjustments to the transaction terms upon certain specified events, the circumstances generally under which final settlement of the ASR Agreement may be accelerated or extended or the ASR Agreement may be terminated early by BofA or Humana, and various acknowledgements and representations made by the parties to each other. At final settlement, under certain circumstances, Humana may be entitled to receive additional shares of Humana common stock from BofA or Humana may be required to make a cash payment or, if Humana elects, deliver shares of Humana common stock to BofA. All of the shares of Humana common stock delivered to Humana under the ASR Agreement will be held in treasury or retired.
