Summary judgment dismissing the complaint was properly granted on the ground that there is no evidence of conduct on defendant's part linking it to plaintiff and evincing its understanding of plaintiffs reliance on the closing balance sheet it certified, ( see Credit Alliance Corp. v Arthur Andersen Co., 65 NY2d 536, 551; see e.g. Security Pac. Bus. Credit v Peat Marwick Main Co., 79 NY2d 695, 704-706; William Iselin Co. v Mann Judd Landau, 71 NY2d 420, 425-427). Plaintiffs motion for a joint trial was properly denied as moot in view of the grant of summary judgment dismissing the complaint. The grant of summary judgment also necessarily required denial of plaintiffs cross motion for leave to amend the complaint ( see Buckley Co. v City of New York, 121 AD2d 933, 934-935, lv dismissed 69 NY2d 742).
