(B) Same course of conduct. Offenses that do not qualify as part of a common scheme or plan may nonetheless qualify as part of the same course of conduct if they are sufficiently connected or related to each other as to warrant the conclusion that they are part of a single episode, spree, or ongoing series of offenses. Factors that are appropriate to the determination of whether offenses are sufficiently connected or related to each other to be considered as part of the same course of conduct include the degree of similarity of the offenses, the regularity (repetitions) of the offenses, and the time interval between the offenses. When one of the above factors is absent, a stronger presence of at least one of the other factors is required. For example, where the conduct alleged to be relevant is relatively remote to the offense of conviction, a stronger showing of similarity or regularity is necessary to compensate for the absence of temporal proximity. The nature of the offenses may also be a relevant consideration (e.g., a defendant’s failure to file tax returns in three consecutive years appropriately would be considered as part of the same course of conduct because such returns are only required at yearly intervals).
10. In the case of solicitation, misprision, or accessory after the fact, the conduct for which the defendant is accountable includes all conduct relevant to determining the offense level for the underlying offense that was known, or reasonably should have been known, by the defendant.
Background: This section prescribes rules for determining the applicable guideline sentencing range, whereas §1B1.4 (Information to be Used in Imposing Sentence) governs the range of information that the court may consider in adjudging sentence once the guideline sentencing range has been determined. Conduct that is not formally charged or is not an element of the offense of conviction may enter into the determination of the applicable guideline sentencing range. The range of information that may be considered at sentencing is broader than the range of information upon which the applicable sentencing range is determined.
Subsection (a) establishes a rule of construction by specifying, in the absence of more explicit instructions in the context of a specific guideline, the range of conduct that is relevant to determining the applicable offense level (except for the determination of the applicable offense guideline, which is governed by §1B1.2(a)). No such rule of construction is necessary with respect to Chapters Four and Five because the guidelines in those Chapters are explicit as to the specific factors to be considered.
Subsection (a)(2) provides for consideration of a broader range of conduct with respect to one class of offenses, primarily certain property, tax, fraud and drug offenses for which the guidelines depend substantially on quantity, than with respect to other offenses such as assault, robbery and burglary. The distinction is made on the basis of §3D1.2(d), which provides for grouping together (i.e., treating as a single count) all counts charging offenses of a type covered by this subsection. However, the applicability of subsection (a)(2) does not depend upon whether multiple counts are alleged. Thus, in an embezzlement case, for example, embezzled funds that may not be specified in any count of conviction are nonetheless included in determining the offense level if they were part of the same course of conduct or part of the same scheme or plan as the count of conviction. Similarly, in a drug distribution case, quantities and types of drugs not specified in the count of conviction are to be included in determining the offense level if they were part of the same course of conduct or part of a common scheme or plan as the count of conviction. On the other hand, in a robbery case in which the defendant robbed two banks, the amount of money taken in one robbery would not be taken into account in determining the guideline range for the other robbery, even if both robberies were part of a single course of conduct or the same scheme or plan. (This is true whether the defendant is convicted of one or both robberies.)
