Schedule of amounts in accumulated other comprehensive loss (gain) to be recognized over next fiscal year

We amortize the unrecognized prior service credit using a straight-line method over the average remaining service period of the employees we expect to receive benefits under the plan. We amortize the unrecognized net actuarial loss (gain), which is subject to certain averaging conventions, over the average remaining service period of active employees.

Expected long term return on assets and to measure the periodic cost

We use the following assumptions to measure the benefit obligation, compute the expected long-term return on assets, and measure the periodic cost for our defined benefit pension plans and other post-retirement benefit plans for the years ended December 31:

Review of historical returns

We calculate the present value of expected future pension and post-retirement cash flows as of the measurement date using a discount rate. We base the discount rate on yields for high-quality, long-term bonds with durations similar to that of our projected benefit obligation. We base the expected return on our plan assets on current and expected asset allocations, as well as historical and expected returns on various categories of plan assets. We routinely review our historical returns along with current market conditions to ensure our expected return assumption is reasonable and appropriate.

	2020		2019
Assumed Health Care Cost Trend Rates at December 31:

Medical claims - pre age 65	6.44	%	6.40	%

Prescription drugs claims - pre age 65	8.78	%	8.80	%
Prescription drugs claims - post age 65	8.63	%	8.60	%
Rate to which the cost trend is expected to decline (the ultimate trend rate)
