My first question would be: do I trust the company to be around that long? The pension payout is someone's amortization of the invested value of this same money--something you could probably match with ease in an IRA with index funds. So, if you can leave it alone yourself, such an account gives you money in the bank. The company's pension (assuming in the US) is insured by the PBGC, so with such a small amount is likely to be fully insured. But the PBGC itself has funding issues. Whatever the end scenario, you have put this piece of your future in someone else's hands.
In the end, you have to understand the community you are in, when you posed the question: everyone here is going to take control, if that's an option. If you do not, then you can think of this pension as part of the bond portion of your asset allocation, and be more aggressive with your stock allocation than you would be without it.
