Managing Pension cost is a challenge for every Administration. If you are the Chief of NYC Office of Actuary and ask to perform Sensitivity Analyses for OPEB Eligibility Changes to

determine potential cost saving opportunities, you might recommend

		Increasing the vesting period by 1 year means that employees who quit or withdraw during that 1 additional year will not be OPEB eligible when they retire;
		Decreasing the vesting period by 1 year
		No change because vesting peirod has no impact on pension liability calculation
		Lower the interest assumption
