Weighted Average Assumptions Used to Determine Benefit Obligations and Net Periodic Benefit Cost

Weighted average assumptions used to determine benefit obligations and net periodic benefit cost consisted of the following:

	2017		2016		2015
Benefit obligation assumptions:
Discount rate	3.92 – 3.78%		4.16 – 3.95%		3.80	%
Rate of compensation increase	—	%	—	%	—	%
Net periodic benefit cost assumptions:(1)
Discount rate	4.16	%	3.80	%	4.65 – 4.10%
Rate of compensation increase	—	%	—	%	—	%
Expected return on plan assets(2)	6.50	%	6.50	%	7.00 – 6.50%

(1) For fiscal 2017 and prior, net periodic benefit cost is measured using weighted average assumptions as of the beginning of each year.

(2) Expected return on plan assets is estimated by utilizing forward-looking, long-term return, risk and correlation assumptions developed and updated annually by Supervalu. These assumptions are weighted by the actual or target allocation to each underlying asset class represented in the pension plan asset portfolio. Supervalu also assesses the expected long-term return on plan assets assumption by comparison to long-term historical performance on an asset class to ensure the assumption is reasonable. Long-term trends are also evaluated relative to market factors such as inflation, interest rates, and fiscal and monetary policies in order to assess the capital market assumptions.
