w.1: Interest cost = Projected benefit obligation, January 1, 2021 * Interest rate = $850 * 6% = $51
w.2: Gain from expected return on the plan assets = (Plan assets (fair value), January 1, 2021 * Actual return rate on plan assets) - (Plan assets (fair value), January 1, 2021 * Expected return rate on plan assets) = ($900 * 11%) - ($900 * 10%) = $9
