$[$The following information applies to the questions displayed below.$]$

Matthew $(48$ at year$-$end$)$ develops cutting$-$edge technology for SV Inc., located in Silicon Valley. In $2020,$ 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.
