Mario Tellez Verdin appeals the sentence imposed after he pleaded guilty to *1176 one count of importation of marijuana, in violation of 21 U.S.C. §§ 952 and 960. Because Verdin completed his term of incarceration and began his three-year period of supervised release one week before his appeal was argued, we must first decide whether, as the government urges, Ver-din’s appeal is moot. We hold that we have jurisdiction to entertain Verdin’s appeal because a favorable resolution of the sentencing error he asserts could reduce the period of his current term of supervised release upon resentencing. We nevertheless reject Verdin’s claim that the district court erred in imposing a two-level enhancement for obstruction of justice under United States Sentencing Commission, Guidelines Manual, § 3C1.1 (Nov.1998) (“U.S.S.G. § 3C1.1”) for providing a false identity to the probation officer, and affirm the sentence imposed by the district court.
I. BACKGROUND
On June 19, 1999, Verdin w;as arrested for attempting to drive a car carrying approximately 29.91 kilograms of marijuana into the United States from Mexico. Upon his arrest, he produced a copy of a birth certificate for David Wayne Bess, born on January 29,1967, and a California Identification Card bearing Mr. Bess’s name.
Government agents investigated Ver-din’s involvement in the offense and attempted to confirm his identity. The agents discovered two criminal records for David Wayne Bess located under separate FBI numbers. Verdin’s fingerprints, however, did not match the fingerprints contained in either set of records. Nor did Verdin’s fingerprints match any of the fingerprints in the databases maintained by the Immigration and Naturalization Service or the State of California Department of Justice.
On June 30, 1999, the grand jury returned a two count indictment charging Verdin (under the name David Wayne Bess) with importation of marijuana, in violation of 21 U.S.C. §§ 952 and 960, and possession of marijuana with the intent to distribute, in violation of 21 U.S.C. § 841(a)(1). Verdin later pleaded guilty to count one of the indictment, and count two was dismissed. During the taking of his plea, Verdin adopted “David Wayne Bess” as his nom de guerre, testifying it was his “true name” and pleading guilty as Mr. Bess.
Following Verdin’s guilty plea, the probation officer conducted a presentence interview. Verdin proceeded as David Wayne Bess. He provided additional details about his assumed family life. Verdin informed the probation officer that he was born on January 29, 1967, and that his parents were Charlie R. Bess and Maria Garcia Amarillas. He also reported that he was born as a twin, and that his brother, Daniel Bess, resided in Mexicali.
David Wayne Bess did indeed have a twin brother named Daniel Bess, whom the probation officer was able to contact. Daniel, who had just seen his brother eight months previously, provided an elaborate physical description of David, describing his height and weight and noting several distinctive tattoos, including a tattoo on his stomach of “Chicali,” a large tattoo on his chest of an Hispanic woman wearing a sombrero and holding a gun, and a large tattoo on his back of the Virgin Mary. He also detailed his brother’s criminal record, aspects of which were corroborated by rap sheets for David Wayne Bess (aka: David Garcia). That Verdin did not fit Bess’s physical description, revealed most strikingly by a six to seven inch height difference and the lack of tattoos, was confirmed when Daniel viewed a photograph of Ver-din and failed to recognize him as his brother.
Although the probation report dictated November 12, 1999 concluded that the defendant was not David Wayne Bess, the probation officer was still unable to ascertain Verdin’s true identity. It was not until January 12, 2000, seven months after the arrest, that the probation officer learned Verdin’s true name from defense counsel.
On February 7, 2000, the district court sentenced Verdin to eighteen months im *1177 prisonment and three years of supervised release. In reaching this sentence, the district court increased Verdin’s base offense level by two levels for obstruction of justice under U.S.S.G. § 3C1.1, reasoning that Verdin “did obstruct and impede ... the probation officer’s investigation by providing a false identification to the probation officer,” and that “[t]here is nothing more material than a defendant’s true identity.”
Verdin challenges his sentence on the sole ground that the district court erred in imposing a two-level increase for obstruction of justice.
II. Jurisdiction
At oral argument, Verdin’s counsel informed the court that Verdin had been released from prison the prior week, on October 7, 2000, and had begun serving the first year of his three-year term of supervised release. Relying on
Spencer v. Kemna,
A case becomes moot when it no longer satisfies the case-or-controversy requirement of Article III, section 2, of the Constitution.
Spencer,
An incarcerated criminal defendant’s challenge to his conviction satisfies Article Ill’s case-or-controversy requirement because the ongoing incarceration “constitutes a concrete injury, caused by the conviction and redressable by invalidation of the conviction.”
Id.
In cases involving a challenge to the criminal conviction itself, the existence of collateral consequences sufficient to satisfy the case-or-controversy requirement is presumed.
Id.
at 8,
A different case'is presented, however, once the defendant completes his sentence. In
Spencer,
a habeas petitioner attacked not his convictions for felony stealing and burglary, but the lawfulness of the termination of his parole status. The Court held that Spencer’s challenge to the parole revocation order became moot after he had finished serving the entire term of the sentence underlying the parole revocation.
Spencer,
The Court also rejected Spencer’s claim that he had proved the existence of collateral consequences sufficient to satisfy the case-or-controversy requirement.
Spencer,
In
Palomba,
the defendant also challenged not his conviction, but his sentence, as having been based on an incorrect criminal history calculation, which, he claimed, resulted in a lengthier sentence than should have been imposed.
Palomba,
Contrary to the government’s position,
Spencer
and
Palomba
do not control our decision in this case. Even though Verdin has completed his term of incarceration, this is not a case in which the conclusion whether Verdin has shown collateral consequences in future sentencing determines our jurisdiction. In the context in which
Spencer
and
Palomba
considered this question, the defendant “had argued that the revocation ‘could be used to increase his sentence in a future sentencing proceeding,’ but the Court held that this was not a sufficient injury for standing.”
Palomba,
In contrast, Verdin has a “personal stake in the outcome” of this appeal. Unlike
Spencer
and
Palomba,
Verdin has not completed his entire sentence, but is in the first year of a three-year term of supervised release, which could be affected upon resentencing. If he were to prevail, in decreasing his total offense level, he could be resentenced to a shorter period of supervised release. Therefore, his appeal is not moot because “success for [Verdin] could alter the supervised release portion of his sentence.”
Dawson v. Scott,
In particular, Verdin was sentenced to eighteen months in prison and three years of supervised release. In arriving at the sentence, the district court imposed a two-level increase to Verdin’s base offense level for obstruction of justice, for a total offense level of 15. The guideline range for incarceration, given Verdin’s criminal history category of I, was eighteen to twenty-four months, and the district court sentenced Verdin at the low-end of the guideline range — eighteen months.
*1179 The district court, however, imposed the high-end of the required period of supervised release. Because Verdin possessed less than fifty kilograms of marijuana, his maximum sentence was five years. See 21 U.S.C. § 960(b)(4). That maximum sentence made Verdin’s offense a Class D felony, see 18 U.S.C. § 3559(a)(4), thereby subjecting him to a period of supervised release of two to three years. See U.S.S.G. § 5D1.2(a)(2) (mandating a term of “at least two years but not more than three years for a defendant convicted of a Class ... D felony”).
Should Verdin succeed on this appeal, his offense level would be reduced to thirteen, which carries a guideline range for incarceration of twelve to eighteen months. Although Verdin would remain subject to supervised release even if the district court were to resentence him to the low-end of the guideline range, see 21 U.S.C. § 960(b)(4) (stating that “a term of supervised release of not less than two years” shall be imposed “[i]f a sentence under this paragraph provides for imprisonment”), the district court could reduce the length of supervised release from three years to two. Indeed, with a twelve month sentence, it is only the statute of conviction, not the guidelines, that requires any term of supervised release. See U.S.S.G. § 5Dl.l(a) (term of supervised release not required unless “a sentence of imprisonment of more than one year is imposed, or when required by statute”). Thus, Verdin has a “personal stake in the outcome” of this appeal, and it is not moot.
III. Enhancement for Obstruction of Justice
Verdin challenges the two-level enhancement the district court imposed for obstruction of justice pursuant to U.S.S.G. § 3C1.1. “We review the district court’s interpretation and application of the Sentencing Guidelines
de novo.” United States v. Barnes,
Section 3C1.1 provides:
If (A) the defendant willfully obstructed or impeded, or attempted to obstruct or impede, the administration of justice during the course of the investigation, prosecution, or sentencing of the instant offense of conviction, and (B) the obstructive conduct related to (i) the defendant’s offense of conviction and any relevant conduct; or (ii) a closely related offense, increase the offense level by 2 levels.
U.S.S.G. § 3C1.1 (1998). Verdin argues that section 3C1.1 does not apply to false statements about identity in a prosecution for importing marijuana, relying upon the “plain language” of clause (B) to section 3C1.1, a provision which was added to the guideline under the November 1, 1998 amendments. He argues that clause (B) requires that the obstructive conduct relate to the defendant’s offense of conviction, relevant conduct, or to a related offense and that his false statements regarding his identity bore no relation to his offense of conviction — importation of marijuana.
Before the November 1, 1998 amendment, section 3C1.1 provided for a two-level increase in a defendant’s offense level “[i]f the defendant willfully obstructed or impeded, or attempted to obstruct or impede, the administration of justice during the investigation, prosecution, or sentencing of the instant offense.” U.S.S.G. § 3C1.1 (1997). The application notes specified that “providing materially false information to a probation officer in respect to a presentence or other investigation for the court” warranted an enhancement under this section. U.S.S.G. § 3C1.1, cmt. n. 3(h) (1997). Materially false information included information that, “if believed, would tend to influence or affect the issue under determination.” U.S.S.G. § 3C1.1, cmt. n. 5 (1997).
Under this prior version of section 3C1.1, we consistently approved enhancements for obstruction of justice where a defendant provided materially false information to a probation officer during the
*1180
investigation, prosecution, or sentencing of the defendant for the underlying charge.
See e.g., Barnes,
Verdin concedes that the two-level enhancement for obstruction of justice would have been proper under the prior version of section 3C1.1 as we have applied it. He argues, however, that the addition of clause (B) renders section 3C1.1 more restrictive than before, making it applicable only to obstructive conduct directly related to the offense of conviction.
We reject Verdin’s argument because it is contrary to the plain language of Section 3C1.1 as well as the history and purpose of the November 1, 1998 amendment. According to the Sentencing Commission, the amendment was designed to “resolve[ ] a circuit conflict on the issue of whether the adjustment applies to obstructions that occur in cases closely related to the defendant’s case or only those specifically related to the offense of which the defendant [is] convicted.” U.S.S.G. Supp. to App. C, Amend. 581 (1998). Several circuits, including the Ninth Circuit, had taken the view that the adjustment applied if the defendant obstructed or attempted to obstruct justice in a closely related case. See
United States v. Acuna,
Moreover, even if we were to accept Verdin’s construction of the sentencing guidelines, which we do not, we would find, as did the district court, that Verdin’s false statements about his identity were material to his offense of conviction. As the district court said, “[t]here is nothing more material than a defendant’s true identity; from that all of the other investigation proceeds.” Verdin’s false statements about his identity affected not only the nature of the investigation and the resources and efforts entailed in ascertaining his true identity, but could have affected his very sentence.
See United States v.
*1181
Wilson,
Finally, the application notes to the amended guideline make it clear that “providing materially false information to a probation officer in respect to a presen-tence or other investigation for the court” is grounds for an enhancement under section 3C1.1. U.S.S.G. § 3C1.1, cmt. n. 4(h) (1998);
see also United States v. Takahashi,
The district court did not err when it enhanced Verdin’s offense level for obstruction of justice under U.S.S.G. § 3C1.1 for providing a false identity to the probation officer.
AFFIRMED.
Notes

Palomba
represents a shift in this circuit's law. We had previously held "that a sentence can be challenged, even if it has been completely served, if there might be ‘collateral consequences for a defendant in any possible future sentencing.1
