It's a combination 401K & Profit Sharing Plan. One plan called a "retirement savings plan." It is one of the best perks here, as our profit share (which does not depend on our own contributions) has historically been about 15% of total compensation per year.
DH's company has a pension-ish plan. I really don't know exactly what it is distiguished as but they put 4% in each year until age 45. From age 45-54 they put in 5% annually and 6% annually from age 55 until retirement or whenever you leave the company. In addition to that they have a 403b where they will match half of your contribution up to 6% you/3% them.
