This is used to define your ownership of your pension benefit. Vesting service is calculated beginning with the month in which you are first employed at Rockwell Automation and ending with the month in which your termination date occurs. It is calculated in years and fractions of years (one month equals one-twelfth of a year). For example, if you started working at the Company on May 1, 2008, you would be vested in the Plan on April 2, 2013, if you had continued to work for the Company during those five years.
