Because the transaction involved a foreclosure by BayBank on Continental's assets, the plaintiffs would also have to show that Continental colluded with BayBank in effecting the transfer. See Sheffield Progressive, Inc. v. Kingston Tool Co., 10 Mass. App. Ct. 47, 49, 405 N.E.2d 985 (1980). A transaction could fit within this category even if it was technically insolvent before the transaction if the sale was without fair consideration and had the effect of further diminishing the assets available to creditors.
