NCR Corporation (NYSE:NCR) is in exclusive talks to be sold to Veritas Capital Fund Management, L.L.C, according to people familiar with the matter, in what would be one of the biggest leveraged buyouts as the environment for such deals has become more perilous. A deal could still be weeks away, the people said, and it's far from guaranteed, given that a number of LBOs have been shelved lately because of choppy financing markets.
