rollover IRA

Rollover cash balance plan to IRA?

I have a defined benefit pension in the form of a cash balance plan. At termination, a lump sum is available to me that I can take as an annuity, or roll it over into a tax-deferred account. (I can take it as a lump sum and not roll it over if I wanted to take a bath on taxes.)

I prefer not to count the balance in my current employer account because I don't control the investment and it's very different from the asset allocation in my 403b/401a accounts. If possible, how do I account for rolling the lump sum into my employer accounts at retirement, without it affecting taxes?
