“defined contribution”造句，怎麼用defined contribution造句

Since Chile introduced a fully funded, privately managed defined contribution scheme in 1981, some two dozens countries have converted a portion of their pension system to this arrangement.

First, most are now enrolled in riskier defined contribution (DC) pension schemes [1], where payouts depend on investment performance.

I have supported changing retirement systems from pay-as-you-go to individual account defined contribution systems, as in American IRA and Sep private retirement accounts.
