INTRODUCTION
After Hugo Joseph Camp entered into a plea agreement with the People, the trial court imposed a stipulated split sentence1 of 28 months, with 14 months to be served in local custody and 14 months under mandatory supervision. In preparing for Camp’s release from custody, the probation officer filed a report indicating that the officer had recently learned that Camp was ineligible for mandatory supervision because he was subject to an immigration hold and would be deported upon his release from custody. At a hearing to consider this issue, defense counsel requested that the court terminate the mandatory supervision portion of Camp’s sentence and permit him to be deported. The trial court agreed, terminated the mandatory supervision portion of Camp’s sentence, and ordered Camp released to an immigration enforcement agent.
On appeal, the People contend that the trial court exceeded its jurisdiction in terminating the mandatory supervision portion of Camp’s split sentence. The People maintain that the court’s only options were to order Camp to serve the remainder of the 28-month sentence in custody, or permit him to withdraw his guilty plea. We affirm the trial court’s order.
II.
FACTUAL AND PROCEDURAL BACKGROUND
The People charged Camp with robbery (Pen. Code, § 211)2 (count 1), burglary (§ 459) (count 2), petty theft (§ 484) (count 3), and resisting an officer (§ 148, subd. (a)(1)) (count 4). As to the petty theft charge (§ 484) (count 3), the People alleged that Camp had suffered three prior theft convictions. The People also alleged that Camp had suffered four prison priors (§§ 667.5, subd. (b), 668).
[465]*465One week later, the People and Camp entered into a plea agreement. The plea agreement stated that Camp would plead guilty to grand theft from a person (§ 487, subd. (c)),3 and resisting an officer (§ 148, subd. (a)(1)) (count 4) and would admit having incurred one prison prior (§§ 667.5, subd. (b), 668). The agreement further stated that the People would dismiss the balance of the charges and that Camp would be sentenced to a stipulated split sentence (§ 1170, former subd. (h)(5)(B)(i))4 of 28 months, with 14 months to be served in local custody and 14 months under mandatory supervision.5 That same day, the trial court held a change of plea hearing and accepted Camp’s plea of guilty.
The court sentenced Camp as follows: “Pursuant to the agreement in this case it is the judgment and sentence of this court that this defendant be committed to the custody of the sheriff pursuant to [section] 1170, [subdivision] (H)(5)(B), which is local prison, to serve the term stipulated to be 28 months. H] . . . After the first 14 months he serves actually in custody, the latter portion will be suspended and served in the community under the supervision of the probation department.”
In preparation for Camp’s release from the sheriff’s custody to mandatory supervision, the probation officer filed a report indicating that an agent of Immigration and Customs Enforcement (ICE) had informed the probation officer that Camp was in the United States illegally, and that he would be “deported to South Africa.” The report further stated that Camp would be “released from the Sheriff’s custody directly to ICE custody.” The report then states the following: “[The deportation] will make the offender unavailable for mandatory supervision. Therefore it is recommended that he serve the remainder of his term in the custody of the Sheriff’s Department without release to the community. If this is not possible, due to the stipulated plea agreement, it is recommended that the case be sent back to the sentencing court for a change of plea to address this development.”
The trial court held a hearing concerning the issue raised in the supplemental probation report. At the hearing, defense counsel requested that the court “terminate the mandatory supervision,” in light of the fact that Camp was going to be released to ICE’s custody and then deported. The court asked the [466]*466prosecutor for the People’s position. The prosecutor stated, “The People would, at least, like to see [Camp] serve his custodial commit and then we would submit on the court’s discretion after that.” The court then asked the probation officer for his department’s position. The officer stated, “Nothing further other than it doesn’t sound like he’ll be eligible for mandatory supervision if he’s being deported.”
After the parties submitted the matter to the court, the court terminated Camp’s mandatory supervision and modified his sentence, stating: “Probation is terminated and denied.1®1 He is to serve 364 days in jail with credit for 364, 182, 182 good time/work time credits on top of the actual. [(j[] He can go back to wherever they are going to deport him to. ICE has a hold of him now. The court finds good cause to modify the previously agreed upon sentencing structure in this case.”
The People timely appealed the trial court’s order terminating Camp’s mandatory supervision and modifying his sentence.6

DISCUSSION
The trial court did not act in excess of its jurisdiction in terminating Camp’s mandatory supervision and modifying his sentence
The People claim that the trial court acted in “excess of its jurisdiction by releasing Camp from the remaining 14 months of his suspended sentence [467]*467when he became ineligible for mandatory supervision.” The People argue that the trial court’s act in terminating Camp’s mandatory supervision, without placing him in custody for the remainder of his suspended sentence, resulted in an “unauthorized sentence” that “must be vacated.”8 The People’s contention presents a pure question of law, which requires us to interpret the statutes governing mandatory supervision. Accordingly, we apply the de nova standard of review. (See, e.g., Doe v. Brown (2009) 177 Cal.App.4th 408, 417 [99 Cal.Rptr.3d 209] [“We apply the de nova standard of review to this claim, since the claim raises an issue of statutory interpretation.”].)
Governing law
1. General principles of statutory interpretation
In Doe v. Brown, supra, 177 Cal.App.4th at page 417, this court outlined the following well-established principles of statutory interpretation: “ ‘In construing any statute, “[w]ell-established rules of statutory construction require us to ascertain the intent of the enacting legislative body so that we may adopt the construction that best effectuates the purpose of the law.” [Citation.] “We first examine the words themselves because the statutory language is generally the most reliable indicator of legislative intent. [Citation.] The words of the statute should be given their ordinary and usual meaning and should be construed in their statutory context.” [Citation.] If the statutory language is unambiguous, “we presume the Legislature meant what it said, and the plain meaning of the statute governs.” [Citation.]’ ”
2. Split sentences under the Realignment Act
“Under the Realignment Act, qualified persons convicted of nonserious and nonviolent felonies are sentenced to county jail instead of state prison. [Citation.] Trial courts have discretion to commit the defendant to county jail for a full term in custody, or to impose a hybrid or split sentence consisting of county jail followed by a period of mandatory supervision.” (People v. Catalan (2014) 228 Cal.App.4th 173, 178 [175 Cal.Rptr.3d 41].)
At the time of Camp’s sentencing, section 1170, subdivision (h)(5)(B) permitted a trial court to sentence a defendant to a split sentence as follows:
“(B) [][] (i) For a term as determined in accordance with the applicable sentencing law, but suspend execution of a concluding portion of the term [468]*468selected in the court’s discretion, during which time the defendant shall be supervised by the county probation officer in accordance with the terms, conditions, and procedures generally applicable to persons placed on probation, for the remaining unserved portion of the sentence imposed by the court. The period of supervision shall be mandatory, and may not be earlier terminated except by court order. Any proceeding to revoke or modify mandatory supervision under this subparagraph shall be conducted pursuant to either subdivisions (a) and (b) of Section 1203.2 or Section 1203.3. During the period when the defendant is under such supervision, unless in actual custody related to the sentence imposed by the court, the defendant shall be entitled to only actual time credit against the term of imprisonment imposed by the court. Any time period which is suspended because a person has absconded shall not be credited toward the period of supervision.
“(ii) The portion of a defendant’s sentenced term during which time he or she is supervised by the county probation officer pursuant to this subparagraph shall be known as mandatory supervision . . . .” (Italics added.)
3. Provisions governing the revocation and modification of mandatory supervision
As indicated by the second italicized sentence in section 1170, former subdivision (h)(5)(B)(i), quoted ante, proceedings to revoke or modify mandatory supervision are conducted pursuant to either section 1203.2, subdivisions (a) or (b) or section 1203.3.
Section 1203.2, subdivisions (a) and (b) authorize a trial court to revoke, modify, or terminate the supervision of a defendant subject to mandatory supervision as follows:
“(a) At any time during the period of supervision of a person ... (3) placed on mandatory supervision pursuant to subparagraph (B) of paragraph (5) of subdivision (h) of Section 1170, ... if any probation officer . . . has probable cause to believe that the supervised person is violating any term or condition of his or her supervision, the officer may, without warrant or other process and at any time until the final disposition of the case, rearrest the supervised person and bring him or her before the court or the court may, in its discretion, issue a warrant for his or her rearrest. Upon such rearrest, or upon the issuance of a warrant for rearrest the court may revoke and terminate the supervision of the person if the interests of justice so require and the court, in its judgment, has reason to believe from the report of the probation or parole officer or otherwise that the person has violated any of the conditions of his or her supervision ....
“(b)(1) Upon its own motion or upon the petition of the supervised person, the probation or parole officer, or the district attorney, the court may modify, [469]*469revoke, or terminate supervision of the person pursuant to this subdivision, except that the court shall not terminate parole pursuant to this section.”
Section 1203.3 also permits a court to revoke, modify, or change the supervision of a defendant subject to mandatory supervision.9 Section 1203.3, subdivision (a) provides: “(a) The court shall have authority at any time during the term of probation to revoke, modify, or change its order of suspension of imposition or execution of sentence. The court may at any time when the ends of justice will be subserved thereby, and when the good conduct and reform of the person so held on probation shall warrant it, terminate the period of probation, and discharge the person so held. The court shall also have the authority at any time during the term of mandatory supervision pursuant to subparagraph (B) of paragraph (5) of subdivision (h) of Section 1170 to revoke, modify, or change the conditions of the court’s order suspending the execution of the concluding portion of the supervised person’s term.”
Section 1203.3, subdivision (b) describes the manner by which a court may exercise such authority:
“(b) The exercise of the court’s authority in subdivision (a) to revoke, modify, or change probation or mandatory supervision, or to terminate probation, is subject to the following:
“(1) Before any sentence or term or condition of probation or condition of mandatory supervision is modified, a hearing shall be held in open court before the judge. The prosecuting attorney shall be given a two-day written notice and an opportunity to be heard on the matter, except that, as to modifying or terminating a protective order in a case involving domestic violence, as defined in Section 6211 of the Family Code, the prosecuting attorney shall be given a five-day written notice and an opportunity to be heard.
“(A) If the sentence or term or condition of probation or the term or any condition of mandatory supervision is modified pursuant to this section, the judge shall state the reasons for that modification on the record.
[470]*470“(B) As used in this section, modification of sentence shall include reducing a felony to a misdemeanor.”
4. Application
Section 1170, former subdivision (h)(5)(B)(i) expressly stated that a period of mandatory supervision may be terminated by court order, and contained no limitation of any ldnd on a trial court’s exercise of such authority. Further there was nothing in the text of section 1170, former subdivision (h)(5)(B)(i) that would indicate that a trial court does not have the authority to modify the sentence of a defendant subject to mandatory supervision.
In addition, neither section 1203.2, subdivisions (a) and (b) nor section 1203.3, which govern proceedings to revoke or modify mandatory supervision, contains any language that would require a court to impose the suspended portion of the sentence upon early termination of mandatory supervision. Similarly, neither statute expressly or implicitly restricts a court from modifying a defendant’s sentence. On the contrary, section 1203.3, subdivision (b)(1)(A) expressly states that a court may modify a defendant’s “sentence” or a “term or . . . condition of mandatory supervision.” (§ 1203.3, subd. (b)(1)(A) [“If the sentence ... or the term or any condition of mandatory supervision is modified pursuant to this section, the judge shall state the reasons for that modification on the record.]”; see § 1203.3, subd. (b)(1)(B) [“As used in this section, modification of sentence shall include reducing a felony to a misdemeanor.”]; cf. People v. Leiva (2013) 56 Cal.4th 498, 504 [154 Cal.Rptr.3d 634, 297 P.3d 870] [“Section 1203.3, subdivision (a), empowers the trial court ‘at any time during the term of probation to revoke, modify, or change its order of suspension of imposition or execution of sentence.’ ”].)
The People argue that the trial court was without jurisdiction to modify Camp’s sentence because in “[Dix v. Superior Court (1991) 53 Cal.3d 442, 455 [279 Cal.Rptr. 834, 807 P.2d 1063]] the California Supreme Court held that where the sentence imposed is a state prison commitment, a trial court lacks authority to substantially modify the original judgment after it has been imposed and executed.” We are not persuaded by this argument.
In Dix, the California Court Supreme Court referred to “the common law rule that the court loses resentencing jurisdiction once execution of sentence has begun.” (Dix v. Superior Court, supra, 53 Cal.3d at p. 455, italics added (Dix).) A trial court’s authority to impose mandatory supervision, however, is entirely statutory. We are aware of no authority that has extended the common law rule referred to in Dix to the mandatory supervision context, and the People offer no reasoned argument for doing so here. [471]*471(Cf. People v. Howard (1997) 16 Cal.4th 1081, 1092 [68 Cal.Rptr.2d 870, 946 P.2d 828] (Howard) [explaining that the common law principle referred to in Dix does not apply in the probation context because “the authority to grant probation and to suspend imposition or execution of sentence is wholly statutory”].)
Extending the common law rule referred to in Dix to the mandatory supervision context would create a conflict with language in section 1203.3, subdivision (b)(1)(A), authorizing a court to modify a defendant’s “sentence” in revoking or modifying mandatory supervision. (See Howard, supra, 16 Cal.4th at p. 1093 [noting that, with respect to a probationer, a trial court “ha[s] authority to reduce a previously imposed but suspended sentence at any time prior to defendant’s rearrest”].) Accordingly, we reject the People’s contention that, under Dix, “once Camp began serving the custodial portion of his sentence, the trial court was without jurisdiction to modify or alter the term of the suspended sentence.”
The People also contend that the trial court’s order terminating Camp’s mandatory supervision without ordering him to serve the suspended portion of his sentence in custody is contrary to the California Supreme Court’s decision in Howard, supra, 16 Cal.4th 1081. In Howard, the California Supreme Court addressed whether, after a probationer has been rearrested, a trial court has discretion in a proceeding “revoking probation, to reduce a probationer’s previously imposed but suspended sentence.” (Id. at p. 1084.) In resolving this issue, the Howard court relied on the “important distinction, in probation cases, between orders suspending imposition of sentence and orders suspending execution of previously imposed sentences.” (Id. at p. 1087.) The Howard court explained that when a trial court suspends imposition of a sentence before placing a defendant on probation, the court has full sentencing discretion when revoking probation. (Ibid.) However, the Howard court further concluded that when a trial court suspends execution of sentence, section 1203.2, subdivision (c)10 restricts a court’s authority to impose a sentence different from that previously imposed. In reaching this conclusion, the Howard court reasoned in part: “In our view, section 1203.2, subdivision (c) . . . gives the court discretion, on revocation and termination of probation, either (1) to revoke the suspension of sentence and commit the probationer to prison for the term prescribed in the suspended sentence, or (2) to decline to revoke the suspension or to order confinement. If the court does order a prison commitment, however, . . . section 1203.2, subdivision (c) . . . [472]*472set[s] forth the rule that the previously suspended judgment shall ‘be in full force and effect.’ ” (Howard, supra, at p. 1094, italics omitted.)
The People contend that the “logic of the Howard decision applies with equal force here,” reasoning that, “[sjection 1170, subdivision (h)(5)(B)(i), which permitted the suspended sentence during mandatory supervision, expressly directs the court to employ the procedures under section 1203.2, the same section addressed in Howard.”
The People’s argument suffers from a fatal textual flaw. Section 1170, former subdivision (h)(5)(B)(i) provided that any proceeding to revoke or modify mandatory supervision “shall be conducted pursuant to either subdivisions (a) and (b) of Section 1203.2 or Section 1203.3.” (Italics added.) Howard is based on section 1203.2, subdivision (c), a provision that has no applicability in the mandatory supervision context. Thus, Howard does not support the People’s contention that the trial court imposed an unauthorized sentence in this case.
In any event, even assuming that section 1203.2, subdivision (c) applies in the mandatory supervision context, the trial court did not impose an unauthorized sentence under the reasoning of Howard. The Howard court interpreted section 1203.2, subdivision (c) as permitting a trial court, in revoking and terminating probation, to “decline to revoke the suspension [of sentence] or to order confinement.” (Howard, supra, 16 Cal.4th at p. 1094, italics added; see ibid, [stating that, upon revocation and termination of probation, “[i]f the court does order a prison commitment” (italics added) the previously suspended judgment shall be in effect].) Thus, even assuming that section 1203.2, subdivision (c) applies in the mandatory supervision context, the trial court was not required, under Howard, to revoke the suspended portion of Camp’s sentence and order him to serve the remainder of the suspended portion of his sentence in custody.
The gist of the dissent is that the majority “disregards the trial court’s limited power to act in the case of a previously imposed and suspended sentence under People v. Howard[, supra, 16 Cal.4th. at p. 1088], and section 1203.2, subdivision (c).” In support of this contention, the dissent argues that our conclusion that section 1203.2, subdivision (c) has no application in the mandatory supervision context is “contrary to the California Supreme Court’s recent decision in People v. Scott [(2014) 58 Cal.4th 1415, 1424 [171 Cal.Rptr.3d 638, 324 P.3d 827]].” (Dis. opn., post, at p. 477, fn. 2.)
Our conclusion is not contrary to Scott. In fact, Scott did not even involve mandatory supervision. Rather, the Supreme Court considered whether the Realignment Act applied to defendants who were placed on probation before [473]*473the operative date of the Realignment Act. (See People v. Scott, supra, 58 Cal.4th at p. 1419 (Scott) [considering “the applicability of the Realignment Act to the category of defendants who, prior to October 1, 2011, have had a state prison sentence imposed with execution of the sentence suspended pending successful completion of a term of probation, and who, after October 1, 2011, have their probation revoked and are ordered to serve their previously imposed term of incarceration” (italics added)].) Further, there is nothing in Scott that suggests that section 1203.2, subdivision (c) applies in the mandatory supervision context, and the dissent cites no such language.
In addition, as noted previously, the statute that authorizes the imposition of split sentences provided that “subdivisions (a) and (b) of Section 1203.2 or Section 1203.3” (§ 1170, former subd. (h)(5)(B)(i), italics added) apply to proceedings to revoke or modify mandatory supervision, and made no reference to section 1203.2, subdivision (c). Moreover, section 1203.2, subdivision (c) expressly applies “[u]pan any revocation and termination of probation,” and does not refer to the revocation or termination of mandatory supervision. (Italics added.) In short, section 1170, subdivision (h)(5)(B) does not “mean [that] all terms, conditions, and procedures of probation apply to mandatory supervision.” (People v. Rahbari (2014) 232 Cal.App.4th. 185, 193 [181 Cal.Rptr.3d 220], italics altered [citing amendments to § 1203.2 made following the passage of § 1170, subd. (h)(5)(B)].)11
The People note that California Rules of Court,12 rule 4.435(b)(2) provides, “If the execution of sentence was previously suspended, the judge must order that the judgment previously pronounced be in full force and effect and that the defendant be committed to the custody of the Secretary of the Department of Corrections and Rehabilitation for the term prescribed in that judgment.” However, what the People fail to acknowledge is that this provision applies only “when the sentencing judge determines that the defendant will be committed to prison.” (Rule 4.435(b), italics added.) When read in its entirety, rule 4.435(b) does not support the People’s contention that the trial court was required to imprison Camp upon terminating mandatory supervision.
The People also note that, for purposes of probation, section 1203.3 allows the court to “ ‘terminate the period of probation,’ ” and also “ ‘discharge the [474]*474person so held,’ ” (italics added by the People), but that the discharge language is absent from the sentence addressing the court’s authority to terminate mandatory supervision.13 The People contend that this distinction demonstrates that the Legislature “implicitly recognized” that a trial court is not permitted to terminate a period of mandatory supervision early without ordering the defendant into custody. We disagree.
As noted previously, section 1170, subdivision (h)(5)(B) expressly authorizes a trial court to terminate a defendant’s mandatory supervision prior to the conclusion of the period of supervision initially ordered by the court. In addition, neither former section 1170, subdivision (h)(5)(B)(i), nor subdivisions (a) and (b) of section 1203.2 or section 1203.3 contains any language that would suggest that a court’s power to terminate mandatory supervision is restricted in any manner. (Compare with § 1203.2, subd. (b)(1) [providing “the court shall not terminate parole pursuant to this section” (italics added)].)
If the Legislature intended to restrict a trial court’s sentencing authority upon the revocation and termination of mandatory supervision, we presume that it would have adopted statutory language evincing such intent. For example, the Legislature could have drafted the statute to state, “Upon any revocation and termination of mandatory supervision, the court shall revoke the suspension of execution of sentence and order that the judgment shall be in full force and effect,” thereby requiring the court to impose the suspended portion of the custodial term. (Cf. § 1203.2, subd. (c) [providing that “[u]pan any revocation and termination of probation,” that “ if the judgment has been pronounced and the execution thereof has been suspended, the court may revoke the suspension and order that the judgment shall be in full force and effect”].) In the absence of any such statutory language, we reject the People’s argument that section 1203.3 contains an implicit limitation on the trial court’s sentencing authority when terminating mandatory supervision.
Finally, we observe that the People’s position that a trial court lacks jurisdiction to terminate a period of mandatory supervision without placing the defendant in custody would mean, as a practical matter, that a trial court would be unable to terminate mandatory supervision early based on a defendant’s good behavior. As J. Couzens and T. Bigelow state in their treatise, Felony Sentencing After Realignment, “rewarding good behavior [475]*475[generally] does not translate into additional custody time.” (Couzens & Bigelow, Felony Sentencing After Realignment (rev. Mar. 4, 2014) p. 23; <http://www.courts.ca.gov/partners/documents/felony_sentencing.pdf> [as of Jan. 12, 2015].)14 In discussing whether a trial court may terminate a defendant’s mandatory supervision without placing the defendant in custody, Couzens and Bigelow explain: “It is not logical to conclude the Legislature intended that a court must order a defendant into custody once he has shown the interests of justice no longer demonstrate a need for further supervision. It is logical for the Legislature to grant the court authority to terminate mandatory supervision early when the defendant has reformed and because the mandatory supervision portion of the sentence occurs after the custody portion has been completed.” (Couzens & Bigelow, Felony Sentencing After Realignment, supra, at p. 23.)
In an attempt to avoid this absurd result, the dissent offers an interpretation of section 1203.3, subdivision (a) that has no basis in the text of the applicable statutes. The dissent concludes that a trial court’s “sole authority” to terminate mandatory supervision is “on grounds of a defendant’s good conduct and reform, if the ends of justice are served.” The only support the dissent offers in support of this assertion is the following sentence of section 1203.3, subdivision (a): “The court may at any time when the ends of justice will be subserved thereby, and when the good conduct and reform of the person so held on probation shall warrant it, terminate the period of probation, and discharge the person so held.”15 (§ 1203.3, subd. (a), italics added.) On its face, this provision expressly authorizes the court to terminate probation for good conduct. We decline to interpret this provision as limiting a trial court’s authority to terminate a period of mandatory supervision.
[476]*476Accordingly, we conclude that the trial court did not act in excess of its jurisdiction in terminating Camp’s mandatory supervision and in modifying his sentence.16

DISPOSITION
The trial court’s order terminating Camp’s mandatory supervision and modifying his sentence is affirmed.
