                         OPINION

TASHIMA, Circuit Judge:

   The United States appeals the sentence imposed on Larry
James Grissom following Grissom’s guilty plea and convic-
tion for distribution of cocaine base in violation of 21 U.S.C.
§ 841(a). The government contends that the district court
erred in rejecting quantities of crack cocaine from two dis-
missed counts when calculating Grissom’s base offense level
under     the    United     States   Sentencing      Guidelines
(“Guidelines”). It argues that the quantities, properly consid-
ered, would have resulted in a Guidelines range 21 months
higher than the sentence imposed. We have jurisdiction pursu-
ant to 18 U.S.C. § 3742(b) and 28 U.S.C. § 1291, and we
vacate Grissom’s sentence and remand.

                      BACKGROUND

   On July 5, 2005, a witness cooperating with federal agents
arranged to purchase one ounce of crack cocaine from Gris-
som in the parking lot of a Best Buy store in East Palo Alto.
A short time later, the witness and Grissom completed the
transaction.

   Less than a week later, on July 11, 2005, a cooperating wit-
ness contacted an individual named Larry Darnell Hill, Jr., to
arrange the purchase of two ounces of crack cocaine. Hill told
                       UNITED STATES v. GRISSOM                        4017
the witness to contact Grissom, who arranged for the transac-
tion to take place in the parking lot of the same Best Buy
store. After the transaction was completed, Grissom notified
the witness that the delivery was underweight, and arranged
to provide the difference in amount1 the next day. Grissom,
accompanied by Hill, completed that transaction in the park-
ing lot of an Office Depot store in East Palo Alto.

   On July 19, 2005, federal agents once again arranged with
a witness to purchase once ounce of crack cocaine from Hill.
This time, Hill instructed the witness to meet him at a resi-
dence in East Palo Alto to complete the sale. Once at the pre-
arranged location, the witness observed both Hill and Grissom
approaching on the street. Hill stopped half a block away,
while Grissom completed the sale outside of the residence.

   Based on these three incidents, Grissom was indicted on
three counts of knowingly and intentionally distributing a
mixture and substance containing cocaine base in violation of
21 U.S.C. § 841(a) in the amounts of 28, 49, and 28 grams,
respectively. He subsequently entered into a plea agreement
in which he agreed to plead guilty to Count Two, charging
him with distribution of 49 grams of cocaine base, in
exchange for the dismissal of Counts One and Three. Regard-
ing his sentence, Grissom also agreed to a base offense level
of 32 and that, alternatively, his base offense level would be
34, if the court found that he was a career offender. The par-
ties did not reach agreement as to Grissom’s criminal history,
and Grissom reserved his right to argue in favor of a down-
ward departure from the calculated sentence range.
  1
    The government notes that there is a discrepancy between the total
amount of crack cocaine charged in the three counts of the indictment, 105
grams, and the amount attributed to Grissom in the Presentence Investiga-
tion Report, 113 grams. The difference most likely resulted from the fail-
ure of the indictment to include the amount left out of the underweight
delivery. For sentencing purposes, the difference in amounts is not mate-
rial, and we will refer to the total amount as 105 grams for the sake of con-
sistency.
4018              UNITED STATES v. GRISSOM
   Both parties, in their respective sentencing memoranda,
accepted the Guideline calculations of the Presentence Inves-
tigation Report (“PSR”), which set the base offense level at
32. Moreover, at the sentencing hearing, both parties accepted
as true all material facts as set out in the PSR. The district
court, however, expressed hesitation with the sentencing
range advocated by the government:

    Mr. Grissom pled guilty to one count which involved
    49 grams. Right?

    ...

    He did not plead guilty to the other two counts. The
    other two counts involved additional grams. He was
    not charged with the conspiracy, he wasn’t swooped
    up in a conspiracy; and I guess you could say that
    perhaps every time there is another offense of a simi-
    lar nature, that somehow is relevant conduct. But
    when you do that, you’re essentially saying, “Okay.
    We are working out a deal with you. You plead
    guilty to one count and we’ll dismiss the other two,”
    when in reality it doesn’t amount to dismissing the
    other two because you’re still going to count them
    out anyway; and as a result — you know — I think
    the base offense level — I am going to change to
    read 3[0], level 3[0], which I think reflects the 49
    grams. Correct? That reduces it to an adjusted
    offense level of 3[0] with acceptance of responsibil-
    ity, and line 25 [Adjusted Offense level after accep-
    tance of responsibility], it reduces it to a level 27.

The district court then continued without interruption to dis-
cuss career offender status:

    Not only do I not think that these prior convictions
    really justify a career offender status; I don’t even
    know what they mean — at least what the first one
                   UNITED STATES v. GRISSOM                 4019
    means at paragraph 31. And I think that as a result,
    the criminal history scoring overstates his criminal
    history . . . . I think that what more accurately is
    reflected is a criminal history category of a level
    three rather than a level four, to say nothing of
    pumping up to career offender status.

The district court further discussed substantive reasonableness
before selecting a sentence of 87 months, which is the low
end of the range for a level 27 sentence with a Criminal His-
tory Category of III. After explaining its reasons for not
departing downward to the “bottom of the mandatory [statu-
tory] minimum” of 60 months, the court asked whether there
was “any legal cause why sentence should not be pro-
nounced[.]”

   The government responded, “No, your honor. I would sim-
ply note the government’s objection on the record.” At that
point, the court stated, “I know. You know what you can do
with that. Take it to appellate court, if that’s what you want
to do. I don’t think it’s worth it myself, but that’s something
you have to decide.” This appeal followed.

                 STANDARD OF REVIEW

                                I

   We must first decide whether the government forfeited its
objection to the district court’s calculation of Grissom’s sen-
tence by failing to state with specificity the asserted legal
error committed by the district court. Parties must present
objections to a sentence to the district court in order to assure
that they will be considered on appeal. United States v. Vieke,
348 F.3d 811, 813 (9th Cir. 2003).

  [1] In order for an objection to preserve a sentencing issue
on appeal, it must have a specific substantive basis. Id. at 813.
A specific objection “provides the district court with an
4020                UNITED STATES v. GRISSOM
opportunity to address the error in the first instance and
allows this court to engage in more meaningful review.”
United States v. Santiago, 466 F.3d 801, 803 (9th Cir. 2006)
(citation and quotation marks omitted). This standard is not
met when the government lodges a general objection to the
court’s calculation of the defendant’s sentencing offense
levels, then on appeal asserts specific grounds of error. See
United States v. Baker, 63 F.3d 1478, 1500 (9th Cir. 1995)
(finding that general objection did not preserve for review
claimed errors of “(1) failing to increase their offense levels
. . . ; (2) granting . . . a . . . decrease in [an] offense level for
acceptance of responsibility; (3) decreasing [a defendant’s]
offense level . . . for medical reasons; and (4) granting
[another defendant] a . . . decrease in his offense level for
aberrant behavior”). Nor is it met when the government pres-
ents a “pro forma policy objection” to a type of departure
without actually engaging the reasoning of the court. Vieke,
348 F.3d at 813; see also United States v. Bostic, 371 F.3d
865, 871 (6th Cir. 2004) (holding that a statement which “in-
dicated to the district court that the government’s counsel
wished to speak, but . . . did not inform the district court or
defense counsel of the government’s position” was an insuffi-
cient objection); United States v. Riggs, 967 F.2d 561, 565
(11th Cir. 1992) (stating that a litigant “should raise [his or
her] point in such clear and simple language that the trial
court may not misunderstand it”).

   [2] But what happens when the district court indicates that
it has understood, and rejected, the substance of a party’s
objection? This case presents the issue of forfeiture in novel
circumstances. Neither party disputes that the government
objected to the sentence imposed on Grissom. Before the gov-
ernment articulated a basis for its objection, however, the dis-
trict court stated “I know[,]” and the government pursued the
matter no further. The government now contends that its own
general objection, coupled with the district court’s terse state-
ment, reflects that the district court was fully aware of the
government’s legal position regarding relevant conduct.
                   UNITED STATES v. GRISSOM                 4021
    [3] Despite the seeming facial inadequacy of the objection,
we agree with the government that where the district court
indicates that it understands the basis for the objection and
that further argument is not desired, and the record reflects
this understanding, a general objection may suffice to pre-
serve an issue for appeal. As the government argues, the pur-
pose of a specific objection is to allow for meaningful review
by the district court and, if necessary, the appellate panel.
Santiago, 466 F.3d at 803. Thus, the court’s reassurance that
it “know[s]” the substance of a party’s complaint helps to
allay concerns about the ability of the district court to address
it. Cf. United States v. Pineiro, 470 F.3d 200, 204-05 (5th Cir.
2006) (concluding that the government preserved its objection
to recalculating the defendant’s sentence by making state-
ments throughout the sentencing hearing arguing that the prior
calculations were still appropriate); United States v. Curry,
461 F.3d 452, 459 (4th Cir. 2006) (excusing the government’s
failure to object at the end of the sentencing colloquy where
the government argued vigorously throughout the hearing,
such that it “made unmistakably clear its position”).

  [4] Reviewing the record, we are satisfied that the district
court was indeed fully aware of the government’s position
regarding the district court’s calculation of relevant conduct.
First, the government consistently advanced its view that
quantities of crack cocaine from the dismissed counts of the
indictment should count for sentencing purposes. The plea
agreement, PSR, and both parties’ sentencing memoranda all
calculated Grissom’s offense level based on the total amount,
105 grams, rather than the 49 grams charged in the count of
conviction. Neither party challenged this calculation at the
sentencing hearing. Second, the district court’s comments
indicate an awareness that its decision not to consider the
amount from the dismissed counts produced the government’s
objection. After commenting that determining the calculation
based on 105 grams would not “amount to dismissing the
other two [counts] because [the government would] still . . .
count them out anyway[,]” the district court changed the base
4022                   UNITED STATES v. GRISSOM
offense level to “reflect[ ] the 49 grams.” In short, the district
court knew it was deviating from a calculation based on the
total amount. Responding to the government’s objection, the
district court challenged the government to “take it to appel-
late court, if that’s what you want to do.” The district court’s
challenge to the government to appeal strongly suggests the
district court recognized and disagreed with the claimed error.
Therefore, we hold that the government’s objection was suffi-
cient under the circumstances to preserve its objection to the
district court’s calculation of Grissom’s sentence.

                                     II

   Following the Supreme Court’s recent decision in Gall v.
United States, 128 S. Ct. 586 (2007), we employ a two-part
review of sentences. See United States v. Carty, Nos. 05-
10200, 05 30120, 2008 WL 763770, at *5 (9th Cir. Mar. 24,
2008) (en banc). First, we must “ensure that the district court
committed no significant procedural error, such as failing to
calculate (or improperly calculating) the Guidelines range
. . . .” Gall, 128 S. Ct. at 597. Second, “[a]ssuming that the
district court’s sentencing decision is procedurally sound, the
appellate court should then consider the substantive reason-
ableness of the sentence imposed under an abuse-of-discretion
standard.” Id. Prior to Gall, we “review[ed] the district court’s
interpretation of the Sentencing Guidelines de novo, the dis-
trict court’s application of the Sentencing Guidelines to the
facts of a case for abuse of discretion, and the district court’s
factual findings for clear error.” United States v. Cantrell, 433
F.3d 1269, 1279 (9th Cir. 2006) (quotation marks and citation
omitted). We do not read Gall to change that practice.2 There-
  2
    Gall states that “the appellate court must review the sentence under an
abuse-of-discretion standard.” Gall, 128 S. Ct. at 597. This language could
suggest that both procedural and substantive elements are reviewed under
this more deferential standard. Later in the same paragraph, however, fol-
lowing a discussion of procedural errors for which no standard of review
is mentioned, the Court states that “[a]ssuming that the district court’s sen-
                       UNITED STATES v. GRISSOM                        4023
fore, we will remand non-harmless procedural errors, see id.,
and only proceed to review the substantive reasonableness of
procedurally sound sentences.

                              ANALYSIS

   [5] Although the district court is no longer bound by the
Guidelines, it must still consult the Guidelines for advice as
to the appropriateness of a defendant’s sentence. Carty, 2008
WL 763770, at *4. The consultation requirement involves
determining the correct Guidelines range. Id. As the Supreme
Court recently reiterated, “a district court should begin all
sentencing proceedings by correctly calculating the applicable
Guidelines range.” Gall, 128 S. Ct. at 596 (citing Rita v.
United States, 127 S. Ct. 2456 (2007)). Thus, “if the sentence
imposed resulted from an incorrect application of the Sentenc-
ing Guidelines, and the error was not harmless, ordinarily we
will remand to the district court for further sentencing pro-
ceedings, permitting the district court on remand to consider
the proper Guidelines sentence along with other sentencing
factors.” United States v. Menyweather, 447 F.3d 625, 630
(9th Cir. 2006).

  Grissom pleaded guilty to distribution of 49 grams of
cocaine base in violation of 21 U.S.C. § 841(a)(1) (making it
a crime to “manufacture, distribute, or dispense, or possess

tencing decision is procedurally sound, the appellate court should then
consider the substantive reasonableness of the sentence imposed under an
abuse-of-discretion standard.” Id. The Court only explicitly applies the
standard of review to the substantive reasonableness of the sentence;
indeed, the district court in Gall committed no procedural error, see id. at
598, so only substantive reasonableness was at issue in the case. It there-
fore appears that the opinion leaves untouched the preexisting standards
of review for questions of procedural reasonableness. Our recent opinion
in Carty, while also declining to state the standard of review applied to the
district court’s calculation of the Guidelines range, is not to the contrary.
See Carty, 2008 WL 763770, at *5.
4024                   UNITED STATES v. GRISSOM
with intent to manufacture, distribute, or dispense, a con-
trolled substance”). Under 21 U.S.C. § 841(b)(1)(B)(iii), the
crime carries a minimum sentence of 5 years, and a maximum
sentence of 40 years.

   [6] Under the Guidelines, once the district court determines
the guideline most appropriate to the offense of conviction, it
must determine the correct base offense level as dictated by
that particular guideline. U.S. Sentencing Guidelines Manual
(“U.S.S.G.”) § 1B1.1(b) (2005);3 United States v. Crawford,
185 F.3d 1024, 1027 (9th Cir. 1999). The guideline for distri-
bution of cocaine base, § 2D1.1, requires that the court take
into account the quantity of drugs when selecting the base
offense level. U.S.S.G. § 2D1.1(a)(3). Where there are multi-
ple drug transactions, the Application Notes to this guideline
states that “the quantities of drugs are to be added.” U.S.S.G.
§ 2D1.1 cmt. n.6.

   [7] Various portions of the Guidelines make clear the fact
that these quantities are to be added even if they are not part
of the offense of conviction. First, the conduct determining
the offense level is not limited to the conduct underlying the
conviction, but can include “all relevant conduct under
§ 1B1.3 (Relevant Conduct) . . . .” U.S.S.G. § 1B1.1 cmt.
n.1(H). Such relevant conduct applies to crimes where “the
offense level is determined largely on the basis of . . . the
   3
     We pause to note that the edition of the Guidelines Manual used is sig-
nificant in Grissom’s case because of changes to the guideline setting the
base offense levels for quantities of crack cocaine, made effective on
November 1, 2007. See U.S.S.G. §§ 2D1.1(a)(3), (c) (2007); see also
U.S.S.G. app. C amend. 706 (2007). The effect of these changes will be
discussed infra. Unless otherwise noted, however, we will refer to the
2005 Guidelines manual in evaluating the district court’s calculation,
because Grissom was sentenced under the 2005 Guidelines, and that ver-
sion of the Guidelines is still applicable to him on remand. See 18 U.S.C.
§ 3742(g) (requiring a district court to “apply the guidelines . . . that were
in effect on the date of the previous sentencing of the defendant prior to
the appeal . . .”).
                   UNITED STATES v. GRISSOM                 4025
quantity of a substance involved,” U.S.S.G. § 3D1.2(d), and
includes “all acts and omissions . . . that were part of the same
course of conduct or common scheme or plan as the offense
of conviction[.]” U.S.S.G. § 1B1.3(a)(2). See also United
States v. Scheele, 231 F.3d 492, 497 (9th Cir. 2000) (“[A]
defendant who pleads guilty or is convicted of distributing the
equivalent of 300 kg of marijuana will receive the same base
offense level as a defendant who is convicted of distributing
the equivalent of 3000 kg of marijuana, if the sentencing
judge determines that he also distributed an additional 2,700
kg of marijuana.”); U.S.S.G. § 1B1.3 cmt. n.3 (providing an
example where three separate drug sales are counted for pur-
poses of the base offense level even though not all are
charged).

   [8] Moreover, the Guidelines directly address the use of
conduct that might fall outside the scope of a plea agreement.
Guideline § 6B1.2(a) states that “a plea agreement that
includes the dismissal of a charge . . . shall not preclude the
conduct underlying such charge from being considered under
the provisions of § 1B1.3 (Relevant Conduct) in connection
with the count(s) of which the defendant is convicted.” See
also U.S.S.G. § 6B1.2 (Policy Statement) cmt. (“This para-
graph prevents a plea agreement from restricting consider-
ation of conduct that is within the scope of § 1B1.3 . . . in
respect to the count(s) of which the defendant is convict-
ed[.]”). Under this guideline, the fact that the parties agreed
to dismiss the two counts involving 28 grams of crack cocaine
does not affect the district court’s responsibility to calculate
Grissom’s base offense level by taking into account those
amounts.

   [9] Further, courts have held that provisions of the Guide-
lines that use compulsory language require the district court
to consider drug amounts from acts outside the offense of the
conviction, so long as they “were part of the same course of
conduct or common scheme or plan as the offense of convic-
tion[.]” U.S.S.G. § 1B1.3(a)(2). See, e.g., United States v.
4026               UNITED STATES v. GRISSOM
Gordon, 291 F.3d 181, 190 (2d Cir. 2002) (holding that the
district court must consider conduct when it satisfies the
requirements for grouping under U.S.S.G. §§ 3D1.1-2);
United States v. Kemmish, 120 F.3d 937, 940 (9th Cir. 1997)
(same); United States v. Register, 931 F.2d 308, 313 (5th Cir.
1991) (using mandatory language to describe § 1B1.3(a)(2)).

   [10] We are not unmindful of the fact that “[t]he relevant
conduct ‘aggregation’ rule . . . is a powerful prosecutorial
tool[,]” in that “[t]he offense level for a relatively minor drug
crime may be dramatically increased when uncharged drug
quantities introduced at sentencing are aggregated.” United
States v. Wilson, 502 F.3d 718, 722 (7th Cir. 2007) (internal
citations omitted). The district court was clearly concerned
about such an effect in this case:

    The Court: . . . Mr. Grissom pled guilty to one count
    which involved 49 grams. Right?

    Mr. Rotwein: Yes.

    Ms. Morgan-Kelly: Yes.

    The Court: He did not plead guilty to the other two
    counts. . . . [W]hen you do that, you’re essentially
    saying, “Okay. We are working out a deal with you.
    You plead guilty to one count and we’ll dismiss the
    other two,” when in reality it doesn’t amount to dis-
    missing the other two because you’re still going to
    count them out anyway; and as a result — you know
    — I think the base offense level — I am going to
    change to read 3[0], level 3[0], which I think reflects
    the 49 grams. . . .

As noted by the district court, a calculation based on relevant
conduct which includes quantities in the dropped counts may
yield a sentence of the same length as if the defendant was
                      UNITED STATES v. GRISSOM                        4027
convicted by a jury for the total amount charged.4 In light of
the potential severity of this rule, the district court must “care-
fully scrutinize uncharged relevant drug conduct to ensure it
bears the necessary relation to the convicted offense.” Wilson,
502 F.3d at 723 (citation and quotation marks omitted). It can-
not, however, decline to consider conduct that qualifies as rel-
evant under the guideline.

   The district court did not consider drug quantities from the
dismissed counts when calculating Grissom’s sentence. Gris-
som contends that the district court actually made a factual
finding that the dismissed quantities were not part of the same
course of conduct or common scheme or plan as the offense
of the conviction, thereby relieving the district court of the
duty to consider them. We do not agree. Grissom points to the
following statement by the court to support his contention:

      The other two counts involved additional grams. He
      was not charged with the conspiracy, he wasn’t
      swooped up in a conspiracy; and I guess you could
      say that perhaps every time there is another offense
      of a similar nature, that somehow is relevant con-
      duct. But when you do that, you’re essentially say-
      ing, ‘Okay. We are working out a deal with you.
      You plead guilty to one count and we’ll dismiss the
      other two,’ when in reality it doesn’t amount to dis-
      missing the other two because you’re still going to
      count them out anyway[.]

Grissom interprets this to mean “that because the three
offenses did not factually have the characteristics of a con-
  4
   Of course, although relevant conduct has a substantial effect on the
sentencing guidelines range for drug crimes, it does not raise the statutory
minimum or maximum for the crime of conviction. If Grissom had been
convicted by a jury on one of the other counts, for example, he would have
been sentenced under 21 U.S.C. § 841(b)(1)(A) to a term of no less than
10 years, instead of under § 841(b)(1)(B), which requires a minimum sen-
tence of 5 years.

spiracy, which was confirmed by the fact that the government
did not charge Appellee with conspiracy, the conduct underly-
ing the two dismissed counts was not part of the same course
of conduct, common scheme or plan as related to the one
charge.” It is clear from the context of the comment, however,
that the district court was not making a finding that the dis-
missed drug quantities were not relevant conduct, but rather
reacting to the adverse effect of taking such conduct into
account, as discussed above.

   Grissom’s contention that the absence of explicit factual
findings about relevant conduct proves that the district court
found otherwise is likewise lacking in merit. The Guidelines
clearly set out the factors a district must consider in determin-
ing whether assertedly related conduct counts as relevant
under § 1B1.3(a). Comment 9(B) to that guideline notes sev-
eral appropriate factors, including “degree of similarity . . .
regularity . . . and the time interval between the offenses.”
U.S.S.G. §1B1.3 cmt. n.9(B). We have previously stated that
“the sentencing court must consider the conduct’s ‘similarity,
regularity, and temporal proximity’ to the charged offenses.’ ”
United States v. King, 200 F.3d 1207, 1216 (9th Cir. 1999)
(emphasis added) (citation and quotation marks omitted). The
fact that not one of these factors was discussed by the district
court makes it highly unlikely that it intended to make a fac-
tual finding about relevant conduct.

   [11] We thus conclude that the district court made no rele-
vant conduct determination, but instead made an erroneous
legal determination that it was not required to take such con-
duct into account. The district court erred by refusing to con-
sider the dismissed quantities of crack cocaine in calculating
Grissom’s sentence.

                       CONCLUSION

   We note that the most recent version of the Guidelines,
effective November 1, 2007, reduces the base offense level
                   UNITED STATES v. GRISSOM                 4029
for each threshold quantity of crack cocaine by two levels.
See U.S.S.G. §§ 2D1.1(a)(3), (c) (2007); see also U.S.S.G.
app. C amend. 706 (2007). Although Grissom must be resen-
tenced under the 2005 version of the Guidelines, see 18
U.S.C. § 3742(g), on March 3, 2008, he became eligible to
pursue a sentencing modification under 18 U.S.C.
§ 3582(c)(2). See United States v. Ross, 511 F.3d 1233, 1237
n.2 (9th Cir. 2008); Press Release, U.S. Sentencing Comm’n,
U.S. Sentencing Comm’n Votes Unanimously to Apply
Amendment Retroactively for Crack Cocaine Offenses (Dec.
11, 2007), available at http://www.ussc.gov/PRESS/
rel121107.htm.

   We also note that the district court is free to consider on
remand the Supreme Court’s recent decision in which it held
that “it would not be an abuse of discretion for a district court
to conclude when sentencing a particular defendant that the
crack/powder disparity yields a sentence ‘greater than neces-
sary’ to achieve § 3553(a)’s purposes . . . .” Kimbrough v.
United States, 128 S. Ct. 558, 575 (2007); see also United
States v. Casteneda, 511 F.3d 1246, 1248-49 (9th Cir. 2008).

  For the foregoing reasons, we vacate Grissom’s sentence
and remand for resentencing.

  VACATED and REMANDED.
