(b) Reducing a Sentence for Substantial Assistance.
(2) Later Motion. Upon the government’s motion made more than one year after sentencing, the court may reduce a sentence if the defendant’s substantial assistance involved:
(B) information provided by the defendant to the government within one year of sentencing, but which did not become useful to the government until more than one year after sentencing; or
(C) information the usefulness of which could not reasonably have been anticipated by the defendant until more than one year after sentencing and which was promptly provided to the government after its usefulness was reasonably apparent to the defendant.
(4) Below Statutory Minimum. When acting under Rule 35(b), the court may reduce the sentence to a level below the minimum sentence established by statute.
