Tim has worked for one employer his entire career. While he was working, he participated in the employer's defined contribution plan [traditional 401(k)]. At the end of 2020, Tim retires. The balance in his defined contribution plan is $2,000,000 at the end of 2019.(UseExhibit 13-3.)(Leave no answer blank. Enter zero if applicable.)

a.What is Tim's required minimum distribution for 2020 that must be distributed in 2021 if he is 68 years old at the end of 2020?

1. b-1.What is Tim's required minimum required for 2020 if he turns 72 during 2020?

In 2020, Nina contributes 8 percent of her $158,000 annual salary to her 401(k) account. She expects to earn a 9 percent before-tax rate of return. Assuming she leaves this (and any employer contributions) in the account until she retires in 30 years, what is Nina's after-tax accumulation from her 2020 contributions to her 401(k) account? (UseTable 1,Table 2.)(Round your intermediate calculations and final answers to the nearest whole dollar amount.)

a.Assume Nina's marginal tax rate at retirement is 30 percent.

b.Assume Nina's marginal tax rateat retirement is 20 percent.

c.Assume Nina's marginal tax rate at retirement is 40 percent.
