If you go to targetpayandbenefits.com, it will give your breakdown of your pension plan. Spot had stopped offering the plan about 3 years ago to tm's. But, it's better than nothing. You can withdraw against it too.
You are vested in 3 years, no, you can't contribute to it, and it's only a 2 % pension, which was discontinued for new hires Jan 2011. You can't borrow against the pension program, you can borrow off the 401k though.
