What is a 401(k) Loan Provision?
401K accounts, both regular and Roth, generally have loans available. There are maximum amounts that are based on federal limits, and your balance in the program. These rules also determine the amount of time you have to repay the loan, and what happens if you quit or are fired while the loan is outstanding. In these loan programs the loan comes from your 401K funds. Regarding matching funds. This plan is not atypical. Some match right away, some make you wait. Some put in X percent regardless of what you contribute. Some make you opt out, others make you opt in. Some will direct their automatic amounts to a specific fund, unless you tell them otherwise.  The big plus for the fund you describe is the immediate vesting. Some companies will match your investments but then only partially vest the funds. They don't want to put a bunch of matching funds into your account, and then have you leave.  So they say that if you leave before 5 years is up, they will not let you keep all the funds. If you leave after 2 years you keep 25%, if you leave after 3 years you keep 50%... The fact they immediately vest is a very generous plan.
