Opinion by
Judge TERRY.Defendant, Luis Alvarado, appeals the judgment of conviction entered on a jury verdict finding him guilty of two counts each of second degree kidnapping, aggravated robbery with an armed confederate, and aggravated robbery by use of force, threats, or intimidation. He appeals his convictions of one count each of first degree burglary, theft of $15,000 or more, menacing, and conspiracy to commit aggravated robbery, in connection with the same incident. He also appeals the sentences imposed for these crimes. We affirm.
I. Background
Defendant and several other men robbed a pawn shop. Some of the men broke the shop's merchandise cases, stealing the contents. Two men pointed guns at the shop's manager and assistant manager and demanded the keys to the shop's jewelry safes. Defendant and another man directed the managers to a room in the back of the shop, laid them on the floor, and held them there as the other men opened the safes and stole the items inside. The value of the stolen items exceeded $170,000.
II. Jury Question
Defendant contends the trial court erred in giving a supplemental instruction in response to a jury question about complicity, We disagree.
A. Standard of Review
"The trial court must properly instruct the jury on all matters of law." People v. Riley, 240 P.3d 334, 337 (Colo.App.2009) (cert. granted Aug. 16, 2010). There is no reversible error if the jury instructions, when reviewed as a whole, adequately inform the jury of the law. Id. Jury instructions that conform to relevant statutes are generally sufficient and proper. Id. It is within the trial court's sound discretion to determine whether to provide the jury with additional written instructions in response to a jury question. People v. Bass, 155 P.3d 547, 552 (Colo.App.2006)
B. Application
Under Colorado's complicity statute, a defendant may be liable for a crime committed by another person if, "with the intent to promote or facilitate the commission of the offense, he or she aids, abets, advises, or encourages the other person in planning or committing the offense." § 18-1-603, C.R.S. 2010.
Our supreme court has interpreted this statute to require a dual mental state: (1) the complicitor must have the culpable mental state required for the underlying crime committed by the principal, and (2) the com-plicitor must assist or encourage the commission of the crime with the intent to promote or facilitate it. Grissom v. People, 115 P.3d 1280, 1284-85 (Colo.2005); Bogdanov v. People, 941 P.2d 247, 250 (Colo.), amended, 955 *102P.2d 997 (Colo.1997), disapproved of on other grounds by Griego v. People, 19 P.3d 1 (Colo.2001).
Here, the trial court initially gave the following complicity instruction:
A person is guilty of an offense committed by another person if he is a complicitor. To be guilty as a complicitor, the following must be established by the prosecution beyond a reasonable doubt:
1. A crime must have been committed.
2. Another person must have committed all or part of the crime.
3. The defendant must have had knowledge that the other person intended to commit all or part of the crime.
4. The defendant must have had the intent to promote or facilitate the commission of the crime.
5. The defendant must have aided, abetted, advised, or encouraged the other person in the commission or planning of the crime.
This instruction, reflecting the dual mental state requirement, was approved by the supreme court in Bogdanoc, 941 P.2d at 254 n. 10.
During jury deliberations, the jury posed the following question: "On complicity-does someone have to have knowledge of the intent prior to the act being committed or can the person watching the act happen be complicit by observing the act happen know [sic] that at the time the act is occurring that they [sic] are intending to do the act[?]"
In response, the trial court gave the following supplemental instruction: "The defendant must have had knowledge of the other person's intent to commit all or part of the crime either before or at the time the other person committed all or part of the erime." Defendant asserts that this response was improper.
We first consider and reject defendant's contention that the trial court should have referred the jury back to the original complicity instruction, and that it abused its discretion by providing a response.
-In general, if a jury asks for clarification on a point of law, the trial court should provide that clarification unless (1) the jury may be adequately informed by directing its attention to some portion of the original instructions; (2) the request concerns matters not in evidence or questions which do not pertain to the law of the case; or (8) the request would call upon the judge to express an opinion upon factual matters that the jury should determine. Leonardo v. People, 728 P.2d 1252, 1255 (Colo.1986).
When the jury manifests its confusion by submitting to the trial court a question indicating that it does not understand an element of the offense charged or some other matter of law central to the guilt or innocence of the accused, the trial court must clearly and unambiguously clarify that matter for the jury.
Bass, 155 P.3d at 552.
Although defendant here contends that the trial court was required to do as the court did in Bass, namely, to refer the jury back to the original instructions, we conclude that it was not an abuse of the trial court's discretion here to craft and give a correct supplemental complicity instruction. The jury question addressed here was the third posed to the court about the complicity instruction, and the court had already referred the jury back to its original instructions. The trial court expressed its concern about the length of time the jury had been deliberating (more than two days) and the jury's continued confusion about complicity. The court stated, "[Clomplicity [is] a very difficult concept, and {the jury is] obviously struggling with it. So I think to the extent that I can help them with their question, I should." We conclude the trial court did not abuse its discretion in responding to the jury's question. Cf id. at 552-53 (trial court did not abuse its discretion in responding to similar inquiry about complicity instruction by referring jury back to original instructions).
We also reject defendant's contention that the trial court's response lessened the prosecution's burden of proof and evidence production on the elements of complicity by giving the jury a "broader time frame" in which to find defendant was a complicitor. Defendant argues, "Perhaps the knowledge *103element of complicity can be formed either prior to or during the erime's commission, however, that issue is clearly one for the jury to determine on its own and, as Bass contemplated, should be resolved by a reference back to the original complicity and mens rea instruction[s]." Defendant has cited no authority that supports his view that the supplemental instruction given here impermissi-bly lessened the prosecution's burden of proof, and we have found none. Neither the complicity statute nor Bogdanov sets forth a temporal limitation on the knowledge requirement. The requisite knowledge is minimal. See People v. Wilson, 791 P.2d 1247, 1249-50 (Colo.App.1990) (proof of knowledge may be cireumstantial, and "[pjroof that the complicitor had some knowledge of the principal's offense may be sufficient"). We have found no legal authority that would require a complicitor to have advance knowledge of the principal's intent to commit a crime. To the contrary, People v. Wheeler, 772 P.2d 101, 104 (Colo.1989), indicates that roughly contemporaneous knowledge by the complicitor of the principal's intent is sufficient. That part of Wheeler's holding was not addressed in or limited by Bogdanov. See 941 P.2d at 251.
The trial court's supplemental instruction, in combination with the original instruction, correctly informed the jury of the statutory complicity elements and did not lessen the prosecution's burden of proof. Therefore, we conclude the trial court did not err in giving the supplemental instruction.
III. Sentencing
Defendant also contends that his sentences should be vacated because the trial court impermissibly relied on information in the presentence investigation report (PSIR) to ascertain his sentencing status, and improperly applied the enhanced sentencing range based on a factor which was not charged, admitted to by defendant, or found by a jury. We are not persuaded by these assertions. Although defendant argues that the trial court made an improper finding that he was on bond when he committed the charged offenses, its sentencing determination did not depend on defendant's bond status.
A. Legal Standards
A trial court has broad discretion over sentencing decisions, which will not be overturned unless the court abuses that discretion. Lopez v. People, 113 P.3d 713, 720 (Colo.2005). Although we generally review constitutional challenges to sentencing determinations de novo, id., where, as here, a defendant fails to preserve a challenge under Blakely v. Washington, 542 U.S. 296, 801, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), at sentencing, we review such a challenge on appeal for plain error. People v. Miller, 113 P.3d 743, 745 (Colo.2005); People v. Banark, 155 P.3d 609, 611 (Colo.App.2007). Plain error must be both obvious and substantial, and "we will not vacate a sentence for plain error unless the error so undermined the fundamental fairness of the sentencing proceeding as to cast serious doubt on the reliability of the sentence." Banark, 155 P.3d at 611.
"Other than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt." Blakely, 542 U.S. at 301, 124 S.Ct. 2531 (quoting Apprendi v. New Jersey, 530 U.S. 466, 490, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000)). Facts regarding a defendant's prior convictions are "Blakely-exempt." Lopez, 113 P.3d at 723. This prior conviction exemption is not limited to just the fact of conviction. It extends to any facts "regarding" the prior conviction that can be found in conclusive judicial records, such as a defendant's probation or parole status at the time of the offense. People v. Huber, 139 P.3d 628, 633 (Colo.2006); People v. Montoya, 141 P.3d 916, 922-23 (Colo.App.2006)
B. Application
The trial court learned from its review of the PSIR that defendant "was charged in a juvenile case at the time that he committed the offense in question here," and that the juvenile offense would have constituted a felony if committed by an adult. Defendant did not object to the correctness of this information in the PSIR, and the *104information could be found in conclusive judicial records. The trial court further stated:
[UJnder Colorado Revised Statute Section 18-1.3-401, Subsection 9-8.5[sic], this is a sentence enhancer. And so he is subject, then, to a sentencing range which would be the minimum of the presumptive range to twice the maximum of the presumptive range.
It is undisputed that the trial court did not actually impose any enhanced sentences. Nevertheless, defendant asserts that the court misapprehended the available sentencing ranges, and therefore that resentencing is mandated. See People v. Willcoxon, 80 P.3d 817, 822 (Colo.App.2002). We do not agree that the court misapprehended the available sentencing ranges.
Under section 18-1.3-401(9)(a.5), C.R.S. 2010, a trial court must sentence a defendant to at least the minimum of the presumptive range but not more than twice the maximum of the presumptive range if, "[alt the time of the commission of the felony, the defendant was charged with or was on bond for a delinquent act that would have constituted a felony if committed by an adult."
The trial court apparently relied on subsection (a.5) when it noted that defendant had been "charged with a juvenile offense [when] he committed" the crimes in issue here. (We assume the transcript's reference to subsection "(8.5)" was a mistranseription of "(a.5).") Furthermore, aside from showing the date on which defendant was charged with the juvenile offense-a date prior to the pawn shop burglary-the PSIR showed that defendant had been comvicted of the juvenile offense. Because defendant could not have been convicted of the offense without having been charged with it, and because the fact of the prior conviction and its charging date could have been discerned from conclusive judicial records, the facts underlying the trial court's enhancement of the sentencing range were facts "regarding" the prior conviction and were Blakely-exempt. See Huber, 189 P.3d at 633.
Accordingly, we discern no plain error in the trial court's determination that the enhanced sentencing ranges applied, and conclude that resentencing is therefore not required.
The judgment and sentence are affirmed.
