Almost certainly not, but you'd have to check the precise terms terms of your LTD plan to be absolutely sure. I have never seen a plan that offset for 401(k) withdrawals, though, with one slight exception - some plans offset for the portion of a 401(k) withdrawal that represents matching funds paid into the account by your employer. Not many plans offset that, even. Many plans offset for defined-benefit pension plan withdrawals (plans that aren't funded by money you paid into an account over the years, but pay you a benefit based only on years served with the company), but most of them specifically state that they do NOT offset 401(k) withdrawals. If you don't have a copy of your LTD plan to check, ask your employer for one. You'll definitely want to have one handy.
