JUDGMENT
PER CURIAM.
This appeal from a judgment of the United States District Court for the District of Columbia was presented to the court and briefed by the parties. The court has accorded the issues full consideration and has determined that they do not warrant a published opinion. See D.C.Cir. Rule 36(d). For the reasons presented in the accompanying memorandum, it is
ORDERED AND ADJUDGED that the judgment of conviction by the district court be affirmed.
Pursuant to D.C. Circuit Rule 36, this disposition will not be published. The Clerk is directed to withhold issuance of the mandate herein until seven days after resolution of any timely petition for rehearing or rehearing en banc. See Fed. R.App. P. 41(b); D.C.Cir. Rule 41.
MEMORANDUM
Appellant pled guilty to distribution of 50 grams or more of cocaine base in violation of 21 U.S.C. § 841(a)(1) and (b)(l)(A)(iii) (2006).

He appeals his con
*585
viction on the ground that the district court, in imposing a sentence of 150 months’ imprisonment, failed to consider adequately the sentencing factors in 18 U.S.C. § 3553(a). Because the record shows that the district court considered the § 3553(a) factors and understood its sentencing discretion under
Kimbrough v. United States,
At the sentencing hearing, the district court explained that it understood
Kimbrough
and
Gall v. United States,
Appellant contends that the district court improperly treated the Sentencing Guidelines as mandatory, failed adequately to consider and discuss the § 3553(a) factors, and did not adequately consider imposing a sentence partially concurrent with a prison sentence appellant was serving, even though appellant did not raise this issue at the time. Assuming as appellant contends that the
de novo
standard of review applies, we find no error. The record reflects that the district court understood that the Sentencing Guidelines are not mandatory, as it concluded that a guidelines sentence “is greater than necessary to satisfy the statutory purposes under [§] 3553” and imposed a below-guidelines sentence instead. Tr. Dec. 13, 2007 at 10. The district court also satisfied the requirements of § 3553(a) because its discussion of appellant’s sentence “sounds in the terms of § 3553(a), and the court’s references manifest an understanding of its statutory responsibility.”

States v. Simpson,
Notes
. There is an apparent clerical error in the Judgment, which records the offense of conviction as unlawful distribution of 5 grams or more of cocaine base, rather than 50 grams *585 or more, which was the offense to which appellant pled guilty. Separately, we note that due to a subsequent amendment, the amount of cocaine base that would now constitute a comparably punishable violation of § 841(a)(1) is 280 grams. See 21 U.S.C.A. § 841(b)(l)(A)(iii) (West 2010).
