Grouper 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, $294,000 loss; 2017, $94, 500 loss; 2018, $11, 550 loss; and 2019, $26, 250 gain.
