Liquidating Trust, 155 F.3d 644, 654-55 (3d Cir.1998). See also Cureton, 252 F.3d at 273-74 (affirming district court’s denial of plaintiffs post-summary-judgment motion to amend because, among other things, “the motion was filed three years after the complaint was filed” and “the factual information on which the proposed amendment relied was known almost two-and-a-half years before plaintiffs sought leave to amend”). In contrast, courts have granted leave to amend when the delay was less than one year. See e.g., Arthur, 434 F.3d 196 at 204-05 (affirming grant of leave to amend after a delay of eleven months); Dubicz v. Commonwealth Edison Co., 377 F.3d 787, 793 (7th Cir.2004) (<HOLDING>); Roberson v. Hayti Police Dep’t, 241 F.3d 992,
