I have like 20K in a 401K when I worked at Microsoft a long time ago. This is around the 2008 fiasco. I just converted everything to cash. I didn't do a rollover when I changed employers (I think there is some time limit which I have likely exceeded). I've been trying to figure out if I can make use of that cash. The confusion is that the plan I was in was for Microsoft employees. Can I still use their plan's investment options?? I also don't want to incur any tax implication ... literally the cash has been sitting there for years because I am too stupid to figure out all the details. It is just sad :(
