Ordered that the order is affirmed insofar as appealed from, with costs.
The Supreme Court has broad discretion in the supervision of discovery, and its determinations should not be disturbed on appeal unless improvidently made ( see Milbrandt Co., Inc. v. Griffin, 19 AD3d 663; Setsuo Ito v. Dryvit Sys., 5 AD3d 735; Provident Life Cas. Ins. Co. v. Brittenham, 284 AD2d 518). On this record, the Supreme Court providently exercised its discretion in concluding, inter alia, that the additional discovery sought by the plaintiffs was neither material nor necessary to the prosecution of the claims asserted in the complaint ( see CPLR 3101 [a]; Palermo Mason Constr. v. Aark Holding Corp., 300 AD2d 460).
