Employee Stock Purchase Plan

In June 2016, our shareholders adopted our ESPP and approved 12 million shares to be reserved for issuance under the plan. The ESPP permits eligible employees to make payroll deductions to purchase Weatherford stock.  Each offering period has a six-month duration beginning on either March 1 or September 1. Shares are purchased at 90% of the lower of the closing price for our common stock on the first or last day of the offering period.  We issued 3 million shares under the ESPP as of December 31, 2017.
