  Properties of the disrupted NLC beam at the Interaction Point (IP) and
particle loss in the extraction line are analyzed as a function of beam-to-beam
position and angular offset at IP. The simulations show that disruption and
beam loss maximize when the vertical beam separation at IP is about 20 times
the rms vertical beam size. The horizontal offset does not increase the
disruption and the beam loss. The angular offsets cause particle loss in the
extraction line mainly because of the beam orbit oscillations.
