Enrollment Period
If you’re eligible, you may enroll or make changes to your participation and/or contribution amount in the ESPP two times per year — called enrollment periods.
During the ESPP enrollment period, you can elect to participate in the upcoming ESPP offering period by setting aside contributions through payroll deductions. You can contribute 1%–10% of your base pay per pay period. Due to IRS regulations, some participants may be further limited. Enrollment for the offering periods takes place in December and June. Once you're enrolled, your election carries over to future offering periods unless you opt out or select a different percentage.
The percentage you elect will be withheld from each pay period on an after-tax basis. After the offering period closes, your contributions are used to purchase shares of ONEOK common stock. E-Trade will hold the purchased shares in an individual account established for you.
Note: You may not purchase more than $25,000 worth of ONEOK common stock per calendar year, based on the fair market value on the first day of the offering period(s). “Fair market value” generally means the average of the high and low market price for ONEOK common stock on the applicable date.
Offering Period
An offering period is a six-month period from January through June and July through December during which your payroll contributions will accumulate for the purpose of purchasing company stock at the end of each period.
