and extent of that liability.” Id. at 507, quoting Teamsters Pension Fund v. H.F. Johnson, Inc., 830 F.2d 1009, 1013 (9th Cir.1987). Several other cases have similarly concluded that the failure to timely initiate arbitration will result in a waiver of the right to assert defenses to withdrawal liability arising under sections of MPPAA clearly designated for arbitration. See, e.g., Robbins v. Chipman Trucking Inc., 693 F.Supp. 628, 635 (N.D.Ill.1986) (adopting the rule “that by failing to seek arbitration, a party forfeits its opportunity to rais D.Pa.1988) (failure to request review of fund’s withdrawal liability or to initiate arbitration of assessment made fund’s assessment and payment schedule final); Banner Indus. v. Central States Pension Fund, 657 F.Supp. 875, 884 (N.D.Ill.1987) (<HOLDING>), aff'd, 875 F.2d 1285 (7th Cir.), cert.
