Participants may elect to contribute up to 90% of their base salary through payroll deductions, as defined under the provisions of the Plan document, subject to Internal Revenue Code ("Code") limitations. Annually, participants whose deferral election was 0% at the immediately preceding year end are auto enrolled in the Plan with a 6% deferral rate (unless they elect otherwise).
