or (a)(3) of §1B1.3 (Relevant Conduct); and (ii) has resulted in an increase in the Chapter Two or Three offense level for the instant offense. Cases in which only part of the prior offense is relevant conduct to the instant offense are covered under subsection (c).
(B) Inapplicability of Subsection (b).—Subsection (b) does not apply in cases in which the prior offense increased the Chapter Two or Three offense level for the instant offense but was not relevant conduct to the instant offense under §1B1.3(a)(1), (a)(2), or (a)(3) (e.g., the prior offense is an aggravated felony for which the defendant received an increase under §2L1.2 (Unlawfully Entering or Remaining in the United States), or the prior offense was a crime of violence for which the defendant received an increased base offense level under §2K2.1 (Unlawful Receipt, Possession, or Transportation of Firearms or Ammunition; Prohibited Transactions Involving Firearms or Ammunition)).
(C) Imposition of Sentence.—If subsection (b) applies, and the court adjusts the sentence for a period of time already served, the court should note on the Judgement in a Criminal Case Order (i) the applicable subsection (e.g., §5G1.3(b)); (ii) the amount of time by which the sentence is being adjusted; (iii) the undischarged term of imprisonment for which the adjustment is being given; and (iv) that the sentence imposed is a sentence reduction pursuant to §5G1.3(b) for a period of imprisonment that will not be credited by the Bureau of Prisons.
(D) Example.—The following is an example in which subsection (b) applies and an adjustment to the sentence is appropriate:
The defendant is convicted of a federal offense charging the sale of 40 grams of cocaine. Under §1B1.3, the defendant is held accountable for the sale of an additional 15 grams of cocaine, an offense for which the defendant has been convicted and sentenced in state court. The defendant received a nine-month sentence of imprisonment for the state offense and has served six months on that sentence at the time of sentencing on the instant federal offense. The guideline range applicable to the defendant is 12-18 months (Chapter Two offense level of level 16 for sale of 55 grams of cocaine; 3 level reduction for acceptance of responsibility; final offense level of level 13; Criminal History Category I). The court determines that a sentence of 13 months provides the appropriate total punishment. Because the defendant has already served six months on the related state charge as of the date of sentencing on the instant federal offense, a sentence of seven months, imposed to run concurrently with the three months remaining on the defendant’s state sentence, achieves this result.
3. Application of Subsection (c).—
(A) In General.—Under subsection (c), the court may impose a sentence concurrently, partially concurrently, or consecutively to the undischarged term
of imprisonment. In order to achieve a reasonable incremental punishment for the instant offense and avoid unwarranted disparity, the court should consider the following:
(i) the factors set forth in 18 U.S.C. § 3584 (referencing 18 U.S.C.
