Note: A step-child in which an employee's spouse is required to provide at least 50% support, and resides with you 50% of the time is eligible for health, dental, and vision coverage. A step-child is eligible for health coverage regardless of residence and support. Coverage will terminate at the end of the month in which the dependent turns 26. Once a step-child reaches the age of 19 up to their 25th birthday, refer to the appropriate student column above for instruction.
