Marin Corp. has the following beginning-of-the-year present values for its projected benefit obligation and market-related values for its pension plan assets. The average remaining service life per employee in 2016 and 2017 is 10 years and in 2018 and 2019 is 12 years. The net gain or loss that occurred during each year is as follows: 2016, $308,000 loss: 2017, $99,000 loss: 2018, $12, 100 loss: and 2019, $27, 500 gain. (In working the solution, the gains and losses must be aggregated to arrive at year-end balances.) Using the corridor approach, compute the amount of net gain or loss amortized and charged to pension expense in each of the four years, setting up an appropriate schedule
