Computing the coverture fraction for pension value being computed assuming employment as of “cut-off” date (typically separation date):
Coverture is the fraction of the pension’s value that accrued during the marriage. The numerator is the number of days the participant was employed during the marriage. The denominator is the total number of days employed until the earliest of the cut-off date, the earliest retirement date, or the regular retirement date.
The coverture numerator is the number of days from (in MM/DD/YYYY format) 2/14/2000 to 3/19/2010, which is 3,686. The coverture denominator is the number of days from (in M/DD/YYYY format) 2/14/2000 to 3/19/2010, which is 3,686.
The coverture fraction is 3,686 / 3,686 = 1.0000.
