We've had a client whose DB plan termination 5310 filing (submitted 2/15/2000) was reviewed by an IRS agent and finally recommended for approval last week. This week, the filing was "randomly selected for further review" so we still don't have a determination letter after over 13 months! We're wondering how long the "further review" might take. Have any of you had experience with this?

This happened to me once a few years ago, and the delay was about 2 weeks, maybe 3 at most.
