Matthew (48 at year-end) develops cutting-edge technology for SV, Inc. located in Silicon Valley. In 2016, Matthew participates in SV's money purchase pension plan (a defined contribution plan) and in his company's 401(k) plan. Under the money purchase pension plan, SV contributes 15 percent of an employee's salary to a retirement account for the employee up to the amount limited by the tax code. Because it provides the money purchase pension plan, SV does not contribute to the employee's 401(k) plan. Matthew would like to maximize his contribution to his 401(k) account after SV's contribution to the money purchase plan.

a. Assuming Matthew's annual salary is $400,000, what amount will SV contribute to Matthew's money purchase plan? What can Matthew contribute to his 401(k) account in 2016?

b. Assuming Matthew's annual salary is $240,000, what amount will SV contribute to Matthew's money purchase plan? What can Matthew contribute to his 401(k) account in 2016?

c. Assuming Matthew's annual salary is $60,000, what amount will SV contribute to Matthew's money purchase plan? What amount can Matthew contribute to his 401(k) account in 2016?

d. Assume the same facts as c. except that Matthew is 54 years old at the end of 2016. What amount can Matthew contribute to his 401(k) account in 2016?
