description This report reviews the improved method of primary vertex off-line reconstruction. The new method for primary vertex seed finding as well as modified procedure for vertex fit have been briefly described. Results of the primary vertex reconstruction performance are presented and compared to the previous version of the package. Improvement in the primary vertex reconstruction efficiencies is observed. Small but statistically significant bias, coming mostly from the long-living tracks as well as from a bias of the Velo measurements present in the DC06 simulation, affects the determination of the primary vertex position along the beam direction.
