CHAPTER ONE - INTRODUCTION, AUTHORITY, AND GENERAL APPLICATION PRINCIPLES
§1B1.3. RELEVANT CONDUCT (FACTORS THAT DETERMINE THE GUIDELINE RANGE)

(a) Chapters Two (Offense Conduct) and Three (Adjustments).—Unless otherwise specified, (i) the base offense level where the guideline specifies more than one base offense level, (ii) specific offense characteristics and (iii) cross references in Chapter Two, and (iv) adjustments in Chapter Three, shall be determined on the basis of the following:

(1)     (A) all acts and omissions committed, aided, abetted, counseled, commanded, induced, procured, or willfully caused by the defendant; and

(B) in the case of a jointly undertaken criminal activity (a criminal plan, scheme, endeavor, or enterprise undertaken by the defendant in concert with others, whether or not charged as a conspiracy), all acts and omissions of others that were—

(i) within the scope of the jointly undertaken criminal activity,

(ii) in furtherance of that criminal activity, and

(iii) reasonably foreseeable in connection with that criminal activity;

that occurred during the commission of the offense of conviction, in preparation for that offense, or in the course of attempting to avoid detection or responsibility for that offense;

(2) solely with respect to offenses of a character for which §3D1.2(d) would require grouping of multiple counts, all acts and omissions described in subdivisions (1)(A) and (1)(B) above that were part of the same course of conduct or common scheme or plan as the offense of conviction;

(3) all harm that resulted from the acts and omissions specified in subsections (a)(1) and (a)(2) above, and all harm that was the object of such acts and omissions; and

(4) any other information specified in the applicable guideline.

(b) Chapters Four (Criminal History and Criminal Livelihood) and Five (Determining the Sentence).—Factors in Chapters Four and Five that establish the guideline range shall be determined on the basis of the conduct and information specified in the respective guidelines.

(c) Acquitted Conduct.—Relevant conduct does not include conduct for which the defendant was criminally charged and acquitted in federal court, unless such conduct also establishes, in whole or in part, the instant offense of conviction.

Commentary

Application Notes:

1. Sentencing Accountability and Criminal Liability.—The principles and limits of sentencing accountability under this guideline are not always the same as the principles and limits of criminal liability. Under subsections (a)(1) and (a)(2), the focus is on the specific acts and omissions for which the defendant is to be held accountable in determining the applicable guideline range, rather than on whether the defendant is criminally liable for an offense as a principal, accomplice, or conspirator.

2. Accountability Under More Than One Provision.—In certain cases, a defendant may be accountable for particular conduct under more than one subsection of this guideline. If a defendant’s accountability for particular conduct is established under one provision of this guideline, it is not necessary to review alternative provisions under which such accountability might be established.

3. Jointly Undertaken Criminal Activity (Subsection (a)(1)(B)).—

(A) In General.—A “jointly undertaken criminal activity” is a criminal plan, scheme, endeavor, or enterprise undertaken by the defendant in concert with others, whether or not charged as a conspiracy.

In the case of a jointly undertaken criminal activity, subsection (a)(1)(B) provides that a defendant is accountable for the conduct (acts and omissions) of others that was:

(i) within the scope of the jointly undertaken criminal activity;

(ii) in furtherance of that criminal activity; and

(iii) reasonably foreseeable in connection with that criminal activity.

The conduct of others that meets all three criteria set forth in subdivisions (i) through (iii) (i.e., “within the scope,” “in furtherance,” and “reasonably foreseeable”) is relevant conduct under this provision. However, when the conduct of others does not meet any one of the criteria set forth in subdivisions (i) through (iii), the conduct is not relevant conduct under this provision.

(B) Scope.—Because a count may be worded broadly and include the conduct of many participants over a period of time, the scope of the “jointly undertaken criminal activity” is not necessarily the same as the scope of the entire conspiracy, and hence relevant conduct is not necessarily the same for every participant. In order to determine the defendant’s accountability for the conduct of others under subsection (a)(1)(B), the court must first determine the scope of the criminal activity the particular defendant agreed to jointly undertake (i.e., the scope of the specific conduct and objectives embraced by the defendant’s agreement). In doing so, the court may consider any explicit agreement or implicit agreement fairly inferred from the conduct of the defendant and others. Accordingly, the accountability of the defendant for the acts of others is limited by the scope of his or her agreement to jointly undertake the particular criminal activity. Acts of others that were not within the scope of the defendant’s agreement, even if those acts were known or reasonably foreseeable to the defendant, are not relevant conduct under subsection (a)(1)(B).

In cases involving contraband (including controlled substances), the scope of the jointly undertaken criminal activity (and thus the accountability of the defendant for the contraband that was the object of that jointly undertaken activity) may depend upon whether, in the particular circumstances, the nature of the offense is more appropriately viewed as one jointly undertaken criminal activity or as a number of separate criminal activities.

A defendant’s relevant conduct does not include the conduct of members of a conspiracy prior to the defendant joining the conspiracy, even if the defendant knows of that conduct (e.g., in the case of a defendant who joins an ongoing drug distribution conspiracy knowing that it had been selling two kilograms of cocaine per week, the cocaine sold prior to the defendant joining the conspiracy is not included as relevant conduct in determining the defendant’s offense level). The Commission does not foreclose the possibility that there may be some unusual set of circumstances in which the exclusion of such conduct may not adequately reflect the defendant’s culpability; in such a case, an upward departure may be warranted.

(C) In Furtherance.—The court must determine if the conduct (acts and omissions) of others was in furtherance of the jointly undertaken criminal activity.

(D) Reasonably Foreseeable.—The court must then determine if the conduct (acts and omissions) of others that was within the scope of, and in furtherance of, the jointly undertaken criminal activity was reasonably foreseeable in connection with that criminal activity.

Note that the criminal activity that the defendant agreed to jointly undertake, and the reasonably foreseeable conduct of others in furtherance of that criminal activity, are not necessarily identical. For example, two defendants agree to commit a robbery and, during the course of that robbery, the first defendant assaults and injures a victim. The second defendant is accountable for the assault and injury to the victim (even if the second defendant had not agreed to the assault and had cautioned the first defendant to be careful not to hurt anyone) because the assaultive conduct was within the scope of the jointly undertaken criminal activity (the robbery), was in furtherance of that criminal activity (the robbery), and was reasonably foreseeable in connection with that criminal activity (given the nature of the offense).

With respect to offenses involving contraband (including controlled substances), the defendant is accountable under subsection (a)(1)(A) for all quantities of contraband with which he was directly involved and, in the case of a jointly undertaken criminal activity under subsection (a)(1)(B), all quantities of contraband that were involved in transactions carried out by other participants, if those transactions were within the scope of, and in furtherance of, the jointly undertaken criminal activity and were reasonably foreseeable in connection with that criminal activity.

The requirement of reasonable foreseeability applies only in respect to the conduct (i.e., acts and omissions) of others under subsection (a)(1)(B). It does not apply to conduct that the defendant personally undertakes, aids, abets, counsels, commands, induces, procures, or willfully causes; such conduct is addressed under subsection (a)(1)(A).

4. Illustrations of Conduct for Which the Defendant is Accountable under Subsections (a)(1)(A) and (B).—

(A) Acts and omissions aided or abetted by the defendant.—

(i) Defendant A is one of ten persons hired by Defendant B to off-load a ship containing marihuana. The off-loading of the ship is interrupted by law enforcement officers and one ton of marihuana is seized (the amount on the ship as well as the amount off-loaded). Defendant A and the other off-loaders are arrested and convicted of importation of marihuana. Regardless of the number of bales he personally unloaded, Defendant A is accountable for the entire one-ton quantity of marihuana. Defendant A aided and abetted the off-loading of the entire shipment of marihuana by directly participating in the off-loading of that shipment (i.e., the specific objective of the criminal activity he joined was the off-loading of the entire shipment). Therefore, he is accountable for the entire shipment under subsection (a)(1)(A) without regard to the issue of reasonable foreseeability. This is conceptually similar to the case of a defendant who transports a suitcase knowing that it contains a controlled substance and, therefore, is accountable for the controlled substance in the suitcase regardless of his knowledge or lack of knowledge of the actual type or amount of that controlled substance.
In certain cases, a defendant may be accountable for particular conduct under more than one subsection of this guideline. As noted in the preceding paragraph, Defendant A is accountable for the entire one-ton shipment of marihuana under subsection (a)(1)(A). Defendant A also is accountable for the entire one-ton shipment of marihuana on the basis of subsection (a)(1)(B) (applying to a jointly undertaken criminal activity). Defendant A engaged in a jointly undertaken criminal activity and all three criteria of subsection (a)(1)(B) are met. First, the conduct was within the scope of the criminal activity (the importation of the shipment of marihuana). Second, the off-loading of the shipment of marihuana was in furtherance of the criminal activity, as described above. And third, a finding that the one-ton quantity of marihuana was reasonably foreseeable is warranted from the nature of the undertaking itself (the importation of marihuana by ship typically involves very large quantities of marihuana). The specific circumstances of the case (the defendant was one of ten persons off-loading the marihuana in bales) also support this finding. In an actual case, of course, if a defendant’s accountability for particular conduct is established under one provision of this guideline, it is not necessary to review alternative provisions under which such accountability might be established. See Application Note 2.

(B) Acts and omissions aided or abetted by the defendant; acts and omissions in a jointly undertaken criminal activity.—

(i) Defendant C is the getaway driver in an armed bank robbery in which $15,000 is taken and a teller is assaulted and injured. Defendant C is accountable for the money taken under subsection (a)(1)(A) because he aided and abetted the act of taking the money (the taking of money was the specific objective of the offense he joined). Defendant C is accountable for the injury to the teller under subsection (a)(1)(B) because the assault on the teller was within the scope and in furtherance of the jointly undertaken criminal activity (the robbery), and was reasonably foreseeable in connection with that criminal activity (given the nature of the offense).
As noted earlier, a defendant may be accountable for particular conduct under more than one subsection. In this example, Defendant C also is accountable for the money taken on the basis of subsection (a)(1)(B) because the taking of money was within the scope and in furtherance of the jointly undertaken criminal activity (the robbery), and was reasonably foreseeable (as noted, the taking of money was the specific objective of the jointly undertaken criminal activity).

(C) Requirements that the conduct of others be within the scope of the jointly undertaken criminal activity, in furtherance of that criminal activity, and reasonably foreseeable.—

(i) Defendant D pays Defendant E a small amount to forge an endorsement on an $800 stolen government check. Unknown to Defendant E, Defendant D then uses that check as a down payment in a scheme to fraudulently obtain $15,000 worth of merchandise. Defendant E is convicted of forging the $800 check and is accountable for the forgery of this check under subsection (a)(1)(A). Defendant E is not accountable for the $15,000 because the fraudulent scheme to obtain $15,000 was not within the scope of the jointly undertaken criminal activity (i.e., the forgery of the $800 check).
(ii) Defendants F and G, working together, design and execute a scheme to sell fraudulent stocks by telephone. Defendant F fraudulently obtains $20,000. Defendant G fraudulently obtains $35,000. Each is convicted of mail fraud. Defendants F and G each are accountable for the entire amount ($55,000). Each defendant is accountable for the amount he personally obtained under subsection (a)(1)(A). Each defendant is accountable for the amount obtained by his accomplice under subsection (a)(1)(B) because the conduct of each was within the scope of the jointly undertaken criminal activity (the scheme to sell fraudulent stocks), was in furtherance of that criminal activity, and was reasonably foreseeable in connection with that criminal activity.
(iii) Defendants H and I engaged in an ongoing marihuana importation conspiracy in which Defendant J was hired only to help off-load a single shipment. Defendants H, I, and J are included in a single count charging conspiracy to import marihuana. Defendant J is accountable for the entire single shipment of marihuana he helped import under subsection (a)(1)(A) and any acts and omissions of others related to the importation of that shipment on the basis of subsection (a)(1)(B) (see the discussion in example (A)(i) above). He is not accountable for prior or subsequent shipments of marihuana imported by Defendants H or I because those acts were not within the scope of his jointly undertaken criminal activity (the importation of the single shipment of marihuana).
(iv) Defendant K is a wholesale distributor of child pornography. Defendant L is a retail-level dealer who purchases child pornography from Defendant K and resells it, but otherwise operates independently of Defendant K. Similarly, Defendant M is a retail-level dealer who purchases child pornography from Defendant K and resells it, but otherwise operates independently of Defendant K. Defendants L and M are aware of each other’s criminal activity but operate independently. Defendant N is Defendant K’s assistant who recruits customers for Defendant K and frequently supervises the deliveries to Defendant K’s customers. Each defendant is convicted of a count charging conspiracy to distribute child pornography. Defendant K is accountable under subsection (a)(1)(A) for the entire quantity of child pornography sold to Defendants L and M. Defendant N also is accountable for the entire quantity sold to those defendants under subsection (a)(1)(B) because the entire quantity was within the scope of his jointly undertaken criminal activity (to distribute child pornography with Defendant K), in furtherance of that criminal activity, and reasonably foreseeable. Defendant L is accountable under subsection (a)(1)(A) only for the quantity of child pornography that he purchased from Defendant K because he is not engaged in a jointly undertaken criminal activity with the other defendants. For the same reason, Defendant M is accountable under subsection (a)(1)(A) only for the quantity of child pornography that he purchased from Defendant K.
(v) Defendant O knows about her boyfriend’s ongoing drug-trafficking activity, but agrees to participate on only one occasion by making a delivery for him at his request when he was ill. Defendant O is accountable under subsection (a)(1)(A) for the drug quantity involved on that one occasion. Defendant O is not accountable for the other drug sales made by her boyfriend because those sales were not within the scope of her jointly undertaken criminal activity (i.e., the one delivery).
(vi) Defendant P is a street-level drug dealer who knows of other street-level drug dealers in the same geographic area who sell the same type of drug as he sells. Defendant P and the other dealers share a common source of supply, but otherwise operate independently. Defendant P is not accountable for the quantities of drugs sold by the other street-level drug dealers because he is not engaged in a jointly undertaken criminal activity with them. In contrast, Defendant Q, another street-level drug dealer, pools his resources and profits with four other street-level drug dealers. Defendant Q is engaged in a jointly undertaken criminal activity and, therefore, he is accountable under subsection (a)(1)(B) for the quantities of drugs sold by the four other dealers during the course of his joint undertaking with them because those sales were within the scope of the jointly undertaken criminal activity, in furtherance of that criminal activity, and reasonably foreseeable in connection with that criminal activity.
(vii) Defendant R recruits Defendant S to distribute 500 grams of cocaine. Defendant S knows that Defendant R is the prime figure in a conspiracy involved in importing much larger quantities of cocaine. As long as Defendant S’s agreement and conduct is limited to the distribution of the 500 grams, Defendant S is accountable only for that 500 gram amount (under subsection (a)(1)(A)), rather than the much larger quantity imported by Defendant R. Defendant S is not accountable under subsection (a)(1)(B) for the other quantities imported by Defendant R because those quantities were not within the scope of his jointly undertaken criminal activity (i.e., the 500 grams).
(viii) Defendants T, U, V, and W are hired by a supplier to backpack a quantity of marihuana across the border from Mexico into the United States. Defendants T, U, V, and W receive their individual shipments from the supplier at the same time and coordinate their importation efforts by walking across the border together for mutual assistance and protection. Each defendant is accountable for the aggregate quantity of marihuana transported by the four defendants. The four defendants engaged in a jointly undertaken criminal activity, the object of which was the importation of the four backpacks containing marihuana (subsection (a)(1)(B)), and aided and abetted each other’s actions (subsection (a)(1)(A)) in carrying out the jointly undertaken criminal activity (which under subsection (a)(1)(B) were also in furtherance of, and reasonably foreseeable in connection with, the criminal activity). In contrast, if Defendants T, U, V, and W were hired individually, transported their individual shipments at different times, and otherwise operated independently, each defendant would be accountable only for the quantity of marihuana he personally transported (subsection (a)(1)(A)). As this example illustrates, the scope of the jointly undertaken criminal activity may depend upon whether, in the particular circumstances, the nature of the offense is more appropriately viewed as one jointly undertaken criminal activity or as a number of separate criminal activities. See Application Note 3(B).

5. Application of Subsection (a)(2).—

(A) Relationship to Grouping of Multiple Counts.—“Offenses of a character for which §3D1.2(d) would require grouping of multiple counts,” as used in subsection (a)(2), applies to offenses for which grouping of counts would be required under §3D1.2(d) had the defendant been convicted of multiple counts. Application of this provision does not require the defendant, in fact, to have been convicted of multiple counts. For example, where the defendant engaged in three drug sales of 10, 15, and 20 grams of cocaine, as part of the same course of conduct or common scheme or plan, subsection (a)(2) provides that the total quantity of cocaine involved (45 grams) is to be used to determine the offense level even if the defendant is convicted of a single count charging only one of the sales. If the defendant is convicted of multiple counts for the above noted sales, the grouping rules of Chapter Three, Part D (Multiple Counts) provide that the counts are grouped together. Although Chapter Three, Part D (Multiple Counts) applies to multiple counts of conviction, it does not limit the scope of subsection (a)(2). Subsection (a)(2) merely incorporates by reference the types of offenses set forth in §3D1.2(d); thus, as discussed above, multiple counts of conviction are not required for subsection (a)(2) to apply.

As noted above, subsection (a)(2) applies to offenses of a character for which §3D1.2(d) would require grouping of multiple counts, had the defendant been convicted of multiple counts. For example, the defendant sells 30 grams of cocaine (a violation of 21 U.S.C. § 841) on one occasion and, as part of the same course of conduct or common scheme or plan, attempts to sell an additional 15 grams of cocaine (a violation of 21 U.S.C. § 846) on another occasion. The defendant is convicted of one count charging the completed sale of 30 grams of cocaine. The two offenses (sale of cocaine and attempted sale of cocaine), although covered by different statutory provisions, are of a character for which §3D1.2(d) would require the grouping of counts, had the defendant been convicted of both counts. Therefore, subsection (a)(2) applies and the total amount of cocaine (45 grams) involved is used to determine the offense level.

(B) “Same Course of Conduct or Common Scheme or Plan”.—“Common scheme or plan” and “same course of conduct” are two closely related concepts.

(i) Common scheme or plan. For two or more offenses to constitute part of a common scheme or plan, they must be substantially connected to each other by at least one common factor, such as common victims, common accomplices, common purpose, or similar modus operandi. For example, the conduct of five defendants who together defrauded a group of investors by computer manipulations that unlawfully transferred funds over an eighteen-month period would qualify as a common scheme or plan on the basis of any of the above listed factors; i.e., the commonality of victims (the same investors were defrauded on an ongoing basis), commonality of offenders (the conduct constituted an ongoing conspiracy), commonality of purpose (to defraud the group of investors), or similarity of modus operandi (the same or similar computer manipulations were used to execute the scheme).

(ii) 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).

(C) Conduct Associated with a Prior Sentence.—For the purposes of subsection (a)(2), offense conduct associated with a sentence that was imposed prior to the acts or omissions constituting the instant federal offense (the offense of conviction) is not considered as part of the same course of conduct or common scheme or plan as the offense of conviction.

Examples: (1) The defendant was convicted for the sale of cocaine and sentenced to state prison. Immediately upon release from prison, he again sold cocaine to the same person, using the same accomplices and modus operandi. The instant federal offense (the offense of conviction) charges this latter sale. In this example, the offense conduct relevant to the state prison sentence is considered as prior criminal history, not as part of the same course of conduct or common scheme or plan as the offense of conviction. The prior state prison sentence is counted under Chapter Four (Criminal History and Criminal Livelihood). (2) The defendant engaged in two cocaine sales constituting part of the same course of conduct or common scheme or plan. Subsequently, he is arrested by state authorities for the first sale and by federal authorities for the second sale. He is convicted in state court for the first sale and sentenced to imprisonment; he is then convicted in federal court for the second sale. In this case, the cocaine sales are not separated by an intervening sentence. Therefore, under subsection (a)(2), the cocaine sale associated with the state conviction is considered as relevant conduct to the instant federal offense. The state prison sentence for that sale is not counted as a prior sentence; see §4A1.2(a)(1).

Note, however, in certain cases, offense conduct associated with a previously imposed sentence may be expressly charged in the offense of conviction. Unless otherwise provided, such conduct will be considered relevant conduct under subsection (a)(1), not (a)(2).

6. Application of Subsection (a)(3).—

(A) Definition of “Harm”.—Harm” includes bodily injury, monetary loss, property damage and any resulting harm.

(B) Risk or Danger of Harm.—If the offense guideline includes creating a risk or danger of harm as a specific offense characteristic, whether that risk or danger was created is to be considered in determining the offense level. See, e.g., §2K1.4 (Arson; Property Damage by Use of Explosives); §2Q1.2 (Mishandling of Hazardous or Toxic Substances or Pesticides). If, however, the guideline refers only to harm sustained (e.g., §2A2.2 (Aggravated Assault); §2B3.1 (Robbery)) or to actual, attempted or intended harm (e.g., §2B1.1 (Theft, Property Destruction, and Fraud); §2X1.1 (Attempt, Solicitation, or Conspiracy)), the risk created enters into the determination of the offense level only insofar as it is incorporated into the base offense level. Unless clearly indicated by the guidelines, harm that is merely risked is not to be treated as the equivalent of harm that occurred. In a case in which creation of risk is not adequately taken into account by the applicable offense guideline, an upward departure may be warranted. See generally §1B1.4 (Information to be Used in Imposing Sentence); §5K2.0 (Grounds for Departure). The extent to which harm that was attempted or intended enters into the determination of the offense level should be determined in accordance with §2X1.1 (Attempt, Solicitation, or Conspiracy) and the applicable offense guideline.

7. Factors Requiring Conviction under a Specific Statute.—A particular guideline (in the base offense level or in a specific offense characteristic) may expressly direct that a particular factor be applied only if the defendant was convicted of a particular statute. For example, in §2S1.1 (Laundering of Monetary Instruments; Engaging in Monetary Transactions in Property Derived from Unlawful Activity), subsection (b)(2)(B) applies if the defendant “was convicted under 18 U.S.C. § 1956”. Unless such an express direction is included, conviction under the statute is not required. Thus, use of a statutory reference to describe a particular set of circumstances does not require a conviction under the referenced statute. An example of this usage is found in §2A3.4(a)(2) (“if the offense involved conduct described in 18 U.S.C. § 2242”).

Unless otherwise specified, an express direction to apply a particular factor only if the defendant was convicted of a particular statute includes the determination of the offense level where the defendant was convicted of conspiracy, attempt, solicitation, aiding or abetting, accessory after the fact, or misprision of felony in respect to that particular statute. For example, §2S1.1(b)(2)(B) (which is applicable only if the defendant is convicted under 18 U.S.C. § 1956) would be applied in determining the offense level under §2X3.1 (Accessory After the Fact) in a case in which the defendant was convicted of accessory after the fact to a violation of 18 U.S.C. § 1956 but would not be applied in a case in which the defendant is convicted of a conspiracy under 18 U.S.C. § 1956(h) and the sole object of that conspiracy was to commit an offense set forth in 18 U.S.C. § 1957. See Application Note 3(C) of §2S1.1.

8. Partially Completed Offense.—In the case of a partially completed offense (e.g., an offense involving an attempted theft of $800,000 and a completed theft of $30,000), the offense level is to be determined in accordance with §2X1.1 (Attempt, Solicitation, or Conspiracy) whether the conviction is for the substantive offense, the inchoate offense (attempt, solicitation, or conspiracy), or both. See Application Note 4 in the Commentary to §2X1.1. Note, however, that Application Note 4 is not applicable where the offense level is determined under §2X1.1(c)(1).

9. Solicitation, Misprision, or Accessory After the Fact.—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.

10. Acquitted Conduct.—Subsection (c) provides that relevant conduct does not include conduct for which the defendant was criminally charged and acquitted in federal court, unless such conduct establishes, in whole or in part, the instant offense of conviction. There may be cases in which certain conduct underlies both an acquitted charge and the instant offense of conviction. In those cases, the court is in the best position to determine whether such overlapping conduct establishes, in whole or in part, the instant offense of conviction and therefore qualifies as relevant conduct.

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.)

Subsections (a)(1) and (a)(2) adopt different rules because offenses of the character dealt with in subsection (a)(2) (i.e., to which §3D1.2(d) applies) often involve a pattern of misconduct that cannot readily be broken into discrete, identifiable units that are meaningful for purposes of sentencing. For example, a pattern of embezzlement may consist of several acts of taking that cannot separately be identified, even though the overall conduct is clear. In addition, the distinctions that the law makes as to what constitutes separate counts or offenses often turn on technical elements that are not especially meaningful for purposes of sentencing. Thus, in a mail fraud case, the scheme is an element of the offense and each mailing may be the basis for a separate count; in an embezzlement case, each taking may provide a basis for a separate count. Another consideration is that in a pattern of small thefts, for example, it is important to take into account the full range of related conduct. Relying on the entire range of conduct, regardless of the number of counts that are alleged or on which a conviction is obtained, appears to be the most reasonable approach to writing workable guidelines for these offenses. Conversely, when §3D1.2(d) does not apply, so that convictions on multiple counts are considered separately in determining the guideline sentencing range, the guidelines prohibit aggregation of quantities from other counts in order to prevent “double counting” of the conduct and harm from each count of conviction. Continuing offenses present similar practical problems. The reference to §3D1.2(d), which provides for grouping of multiple counts arising out of a continuing offense when the offense guideline takes the continuing nature into account, also prevents double counting.

Subsection (a)(4) requires consideration of any other information specified in the applicable guideline. For example, §2A1.4 (Involuntary Manslaughter) specifies consideration of the defendant’s state of mind; §2K1.4 (Arson; Property Damage By Use of Explosives) specifies consideration of the risk of harm created.
