    Before: ROGERS and SRINIVASAN, Circuit Judges, and
    WILLIAMS, Senior Circuit Judge.
    Opinion for the court filed by Circuit Judge ROGERS.
    ROGERS, Circuit Judge: This appeal challenges orders of
    the Federal Communications Commission denying applications
    to renew 689 wireless spectrum licenses in the 24 gigahertz
    (“GHz”) and 39 GHz bands for failure to meet the “substantial
    service” performance standard during the license term. It
    succeeds only in part. FiberTower Spectrum Holdings, LLC,
    and FiberTower Corporation (hereinafter “FiberTower”)
    contend that the Commission’s interpretation of the performance
    standard as requiring some actual construction in each license
    area conflicts with the Commission’s statutory mandate in 
    47 U.S.C. § 309
    (j)(4)(B). Because this argument was not presented
    to the Commission, see 
    47 U.S.C. § 405
    (a), it is not properly
    before the court and we do not address it. FiberTower also
    contends that the Commission’s interpretation of “substantial
    service” is inconsistent with that standard as originally
    promulgated by the Commission. Review of the text of the
    regulations and the rulemaking record demonstrates this
    argument is not well founded. FiberTower, however, further
    contends that the Commission erred in applying its “substantial
    service” interpretation to forty-two licenses because their
    renewal applications stated construction had occurred. This
    error requires a remand, and we vacate the orders denying
    renewal of those forty-two licenses. As a result, we also vacate
    the orders denying extension and waiver, so the Commission can
    rule on those requests based on an accurate understanding of the
    record.
    I.
    The Communications Act of 1934, as amended, establishes
    3
    a system for licensing the use of radio spectrum, and vests in the
    Commission the exclusive authority to grant radio licenses. See
    
    47 U.S.C. § 301
    . The licenses do not “create any right, beyond
    the terms, conditions, and periods of the license.” 
    Id.
     The
    Commission is authorized to prescribe restrictions and
    conditions necessary to carry out its duties, see 
    id.
     § 303(r), and
    for licenses awarded by auction, see id. § 309(j)(1), it must
    adopt
    performance requirements, such as appropriate
    deadlines and penalties for performance failures, to
    ensure prompt delivery of service to rural areas, to
    prevent stockpiling or warehousing of spectrum by
    licensees or permittees, and to promote investment in
    and rapid deployment of new technologies and
    services.
    Id. § 309(j)(4)(B).
    Under Commission rules, licenses in the 24 and 39 GHz
    bands, at issue here, are awarded for ten years, and the licensee
    must demonstrate “substantial service” in the area covered by
    the license by the time of renewal. See 
    47 C.F.R. §§ 101.67
    ,
    101.17, 101.527; In the Matter of Amendment of the Comm’n’s
    Rules Regarding the 37.0-38.6 GHz and 38.6-40.0 GHz Bands,
    12 FCC Rcd. 18600, ¶ 46 (1997) (“39 GHz Order”). The
    Commission has defined “substantial service” as “service which
    is sound, favorable, and substantially above a level of mediocre
    service which just might minimally warrant renewal.” 
    47 C.F.R. §§ 22.940
    (a)(1)(i), 24.203(d), 101.527(a); see In the Matter of
    Amendments to Parts 1, 2, 87 and 101 of the Comm’n’s Rules to
    License Fixed Services at 24 GHz, 15 FCC Rcd. 16934, ¶ 38
    (2000) (“24 GHz Order”). One way a licensee can show
    “substantial service” is by complying with one of several “safe
    harbors,” which include “a showing of [construction and
    4
    operation of] four [microwave] links per million population
    within a service area or service to an area that has very limited
    access to either wireless or wireline telecommunications
    services.” 24 GHz Order, ¶ 38; see 39 GHz Order, ¶ 46.
    A failure to demonstrate substantial service by the renewal
    deadline “will result in forfeiture of the license.” 
    47 C.F.R. § 101.527
    (c); see 
    id.
     § 101.17(b). The Commission may grant an
    extension of the deadline for showing substantial service if the
    licensee shows that its failure to provide substantial service “is
    due to involuntary loss of site or other causes beyond its
    control.” Id. § 1.946(e)(1). The Commission may also waive
    the substantial service requirement entirely when “[t]he
    underlying purpose of the rule(s) would not be served or would
    be frustrated . . . [and] a grant of the requested waiver would be
    in the public interest,” or when “application of the rule(s) would
    be inequitable, unduly burdensome or contrary to the public
    interest, or the applicant has no reasonable alternative.” Id. §
    1.925(b)(3).
    FiberTower provides “wireless backhaul” — i.e., the
    transmission of voice and data between cell towers and regional
    or national networks — to cellular companies and public
    agencies. It owns over 3,000 licenses in the 11 GHz, 18 GHz,
    and 23 GHz bands, and acquired through a merger in 2006 over
    seven hundred licenses in the 24 GHz and 39 GHz bands, see In
    re Matter of ART Licensing Corp., 23 FCC Rcd. 14116, ¶ 4
    (WTB Oct. 2, 2008) (“2008 Bureau Order”); In re Matter of
    FiberTower Spectrum Holdings LLC, 27 FCC Rcd. 13562, ¶ 2
    (WTB Nov. 7, 2012) (“Bureau Order”). The 24 GHz and 39
    GHz bands are used to provide backhaul service for mobile
    broadband networks, and FiberTower’s licenses in these bands
    cover most of the continental United States. See id. Shortly
    after acquiring the 24 and 39 GHz licenses FiberTower obtained
    an extension of the 2008 substantial service deadlines for its 39
    5
    GHz licenses to June 1, 2012.                   The Wireless
    Telecommunications Bureau, see 
    47 C.F.R. §§ 0.131
    (a), 0.331,
    found that the public interest “would best be served by”
    extending the deadline for the 39 GHz licenses, 2008 Bureau
    Order, ¶ 21, because the Bureau anticipated that mobile
    broadband services, which rely on wireless backhaul, would
    “develop robustly” in the coming years, 
    id. ¶ 20
    . The Bureau
    also cautioned that it did “not believe that a finding of
    substantial service can be made without a demonstration of
    actual construction or operation in the licensed area during the
    license term.” 
    Id. ¶ 16
    . In October 2010, the Bureau granted the
    same extension to June 1, 2012 for FiberTower’s 24 GHz
    licenses.
    In May 2012, FiberTower filed for an extension or a waiver
    of the 2012 deadline with respect to 699 licenses. Two weeks
    later, FiberTower also filed substantial service showings for
    each license. In November 2012, the Bureau found that
    FiberTower had not satisfied the substantial service requirement.
    See Bureau Order, ¶ 18. Ten licenses in which the Bureau
    found there had been “some level of actual construction as of the
    deadline,” 
    id. ¶ 2
    , were not terminated, but the other 689
    licenses were because FiberTower’s “antecedent activities” —
    investing in new technology, developing its own back-office
    operations, acquiring equipment and property, and making its
    spectrum available for lease on the secondary market — could
    not alone “constitute substantial service.” 
    Id.
     ¶ 22 (citing In the
    Matter of Amendment of Part 101 of the Comm’n’s Rules to
    Facilitate the Use of Microwave for Wireless Backhaul and
    Other Uses and to Provide Additional Flexibility to Broadcast
    Auxiliary Service and Operational Fixed Microwave Licensees,
    27 FCC Rcd. 9735, ¶ 104 (2012) (“Wireless Backhaul Order”);
    26 FCC Rcd. 11614, ¶ 114 (2011)). Concluding that
    FiberTower’s failure to “build out” its licenses was a “business
    decision” within its control, the Bureau denied an extension.
    6
    The Bureau also concluded the public interest would not be
    served by waiving the substantial service requirement. See also
    Bureau Order, ¶ 39.
    The Commission affirmed, upon consideration of
    FiberTower’s Application for Review and Petition for
    Reconsideration. In the Matter of FiberTower Spectrum
    Holdings LLC, 28 FCC Rcd. 6822 (2013) (“Order”); 29 FCC
    Rcd. 2493 (2014) (“Reconsideration Order”). The Commission
    endorsed the Bureau’s conclusion, based on prior Commission
    decisions, that FiberTower’s antecedent activities without actual
    construction could not satisfy the substantial service
    requirement. See Order, ¶ 39 & n.156 (citing Wireless Backhaul
    Order, ¶ 104). Agreeing also that FiberTower’s decision not to
    construct links was a voluntary business decision, the
    Commission rejected FiberTower’s claims that the market for
    wireless backhaul was underdeveloped and that there was a lack
    of viable equipment, noting the “explosive growth in demand for
    mobile broadband services since 2008, and [a] corresponding
    demand for backhaul,” Order, ¶ 19, and denied FiberTower’s
    request for extension of the deadline, id.; see also 
    id. ¶ 21
    . And
    concluding that the need to enforce construction requirements
    outweighed any delays in relicensing and the investments
    FiberTower had made, the Commission concluded a waiver was
    unwarranted.      
    Id.

    Reconsideration Order, ¶ 39. FiberTower appeals.
    II.
    FiberTower’ statutory challenge flounders under 
    47 U.S.C. § 405
    (a), which provides:
    The filing of a petition for reconsideration shall not be
    a condition precedent to judicial review . . . except
    where the party seeking such review . . . relies on
    7
    questions of fact or law upon which the Commission,
    or designated authority within the Commission, has
    been afforded no opportunity to pass.
    FiberTower contends that the Commission’s construction
    requirement as a part of demonstrating “substantial service” is
    “at odds with” the statutory goal in 
    47 U.S.C. § 309
    (j)(4)(B) of
    promoting “investment in” new technologies. Appellant’s Br.
    28. But FiberTower failed to make this argument in its
    Application for Review to the Commission, never citing §
    309(j)(4)(B) and instead arguing that the construction
    requirement was an “ill-conceived policy” with “adverse
    consequences contrary to the public interest.” Application for
    Review, In the Matter of FiberTower Corp., at 20, File No.
    5207557, Dec. 7, 2012. Neither did FiberTower present this
    statutory argument in its Petition for Reconsideration.
    FiberTower’s suggestions that it nonetheless afforded the
    Commission an “opportunity to pass” on its statutory argument
    are unpersuasive. First, FiberTower states that “[a] core premise
    of FiberTower’s application for review was that the
    Commission’s policy of disregarding leasing and other activities
    hindered ‘legitimate investment’ and the ‘develop[ment] [of] the
    licensed spectrum.’” Reply Br. 4 (quoting Application for
    Review, at 21–22) (alterations in original). But the Application
    for Review characterized that argument only as illustrating why
    the build-out requirement was “contrary to the public interest,”
    Application for Review, at 20, not that the requirement was
    contrary to § 309(j)(4)(B). The language suggests the sort of
    claim that would normally give rise to judicial review only for
    whether the agency’s action was arbitrary or capricious.
    Second, FiberTower refers to a “white paper” submitted as a
    supplement to its Application for Review that explained why its
    antecedent activities “were consistent with Section 309(j)’s
    mandate of promoting investment and deployment of new
    8
    technologies and services — underscoring that FiberTower’s
    argument was anchored in the statute.” Reply Br. 5. Again, this
    is not an argument that the “build out” requirement violates §
    309(j)(4)(B), and “[t]he Commission need not sift pleadings and
    documents to identify arguments that are not stated with clarity
    by a petitioner.” Bartholdi Cable Co., Inc. v. FCC, 
    114 F.3d 274
    , 279 (D.C. Cir. 1997) (internal quotation marks omitted);
    see also 
    47 C.F.R. § 1.115
    (b)(1). Third, FiberTower states that
    the rulemaking proceedings in which the Commission adopted
    the substantial service rules “were inextricably intertwined with
    Section 309(j).” Reply Br. 5. Even so, FiberTower failed to
    alert the Commission to the statutory argument that it seeks to
    present for the first time on appeal.
    Time Warner Entertainment Co., L.P. v. FCC, 
    144 F.3d 75
    (D.C. Cir. 1998), on which FiberTower relies, is inapposite. In
    that case, the court held that its reasoning in an earlier remand
    had given the Commission an “opportunity to pass” on an issue,
    even though the issue had not been raised in a petition for
    reconsideration. 
    Id.
     at 81–82. The court observed that the logic
    of its prior decision meant it was unreasonable for the
    Commission not to respond on remand. 
    Id.
     The court viewed
    the Commission’s position that the issue had been conceded in
    a pre-remand filing to be “a disingenuous gimmick used to avoid
    a principled response to our remand.” 
    Id. at 81
    . Here, by
    contrast, no other party brought the § 309(j)(4)(B) argument to
    the Commission’s attention. And, unlike in Time Warner,
    FiberTower has not pointed to record evidence that the
    Commission realized FiberTower’s § 309(j)(4)(B) argument was
    before it. It is true that the court in Time Warner noted the
    Commission is afforded the required “opportunity to pass” on an
    issue “necessarily implicated by the argument made to the
    Commission,” giving as an example when a petitioner claimed
    that another party’s conduct violated the Communications Act
    without stating that Commission policies to the contrary also
    9
    conflicted with the Communications Act. Id. at 80 (discussing
    MCI Telecomm. Corp. v. FCC, 
    10 F.3d 842
     (D.C. Cir. 1993);
    Nat’l Ass'n for Better Broad. v. FCC, 
    830 F.2d 270
     (D.C. Cir.
    1987)). But FiberTower’s argument to the Commission was that
    the “build out” policy was unwise, and that argument did not
    “necessarily impl[y]” that the policy was also legally
    impermissible.
    Because FiberTower failed to present its § 309(j)(4)(B)
    argument to the Commission, the Commission never had an
    opportunity to pass on it, and FiberTower thereby failed to
    exhaust its administrative remedies. The argument that the
    construction requirement conflicts with § 309(j)(4)(B) is
    therefore barred under § 405(a) and not properly before the
    court. See Fresno Mobile Radio, Inc. v. FCC, 
    165 F.3d 965
    , 972
    (D.C. Cir. 1999); Bartholdi Cable, 
    114 F.3d at
    279–80.
    III.
    FiberTower also challenges the Commission’s interpretation
    of “substantial service” as requiring construction as a matter of
    law, on the ground that it conflicts with the rule originally
    promulgated by the Commission, and as applied to forty-two
    license renewal applications, where substantial service showings
    stated construction had occurred.
    A.
    In adopting the substantial service standard as the condition
    for license renewal in the 39 GHz and 24 GHz bands, the
    Commission emphasized the need for “flexibility in meeting
    the[] performance requirement” and rejected proposals to
    require a specific number of constructed links per market
    population or geographic area, because “such a build-out
    requirement would be unduly restrictive and burdensome.” 39
    GHz Order, ¶¶ 42, 43; see 24 GHz Order, ¶¶ 37–38. In
    10
    FiberTower’s view, by interpreting “substantial service” to
    include a rigid construction requirement, the Commission
    adopted the very inflexible build-out requirements that it
    rejected during the rulemaking.
    The regulations define “24 GHz Service” as involving
    constructed links. See 
    47 C.F.R. § 101.3
    . In the 39 GHz band,
    a “substantial service showing should include, but not be limited
    to” descriptions of “current service in terms of geographic
    coverage; . . . population served, as well as any additional
    service provided during the license term,” and the “licensee’s
    investments in its system(s) (type of facilities constructed and
    their operational status is required).” 
    Id.
     § 101.17(a)(1), (2), (3).
    Similar materials suffice for the 24 GHz band: “at a minimum,”
    a “report, maps and other supporting documents describing [the
    licensee’s] current service in terms of geographic coverage and
    population,” with the report to include “a description of the
    licensees’ [sic] investments in its operations.”              Id. §
    101.527(b)(1). Nothing in the text indicates that non-
    construction activities alone will suffice to show substantial
    service. It is true that the regulations contemplate the
    submission of information about activities other than
    construction, but that only suggests that non-construction
    activities are relevant, not that they alone can constitute
    substantial service.
    The rulemakings show that in discussing the standard for the
    39 GHz band, the Commission acknowledged that the types of
    services available from 39 GHz providers are “tremendously
    varied.” 39 GHz Order, ¶ 42. It decided not to apply to this
    band the then-existing general requirement to construct one link
    within 18 months of licensure, id. ¶ 39, and declined to replace
    it with “a specific build-out benchmark.” Id. ¶ 43 (emphasis
    added). The performance standards that it rejected as too rigid
    involved specific build-out requirements — “four links per 100
    11
    square kilometers . . . within 18 months,” “a specific number of
    links, increasing over time, per geographic area,” or “a specific
    number of link installations based on the market’s population.”
    Id. ¶¶ 43, 44, 45. The Commission explained that the specificity
    of those construction requirements did “not adequately take into
    account the differences among licensees,” id. ¶ 44, such as
    varying market size, population density, and services offered, id.
    ¶¶ 44–46. But in providing examples for what might satisfy
    substantial service, the Commission still described activities that
    involved link construction. See 24 GHz Order, ¶ 38; 39 GHz
    Order, ¶¶ 42 & n.97, 46. For instance, its “examples of
    presumed substantial service” were “based on a specific number
    of links per population.” Id. ¶ 42. The one “showing tailored to
    a particular type of operation” it described involved “giv[ing]
    greater weight to a high capacity link than is recognized by the
    specific build-out option.” Id. ¶ 42 n.97. In addition, the
    Commission rejected “the arguments of some commenters that
    a build-out requirement should not be imposed” at all. Id. ¶ 50.
    The Commission did not state that the flexibility it sought in
    adopting “substantial service” as the performance standard
    extended to allowing license renewal where there had not been
    any construction. Rather, the Commission described its
    approach as a “build-out/renewal requirement[]” that would
    “give licensees a sufficient opportunity to construct their
    systems.” 39 GHz Order, ¶¶ 47, 49.
    FiberTower’s reference to other regulations that contrast
    “substantial service” with specific build-out requirements is also
    unavailing. Although these regulations list different types of
    “performance or build-out requirement[s]” — to include “e.g.,
    a requirement that the licensee construct and operate one or
    more specific facilities, cover a certain percentage of geographic
    area, cover a certain percentage of population, or provide
    substantial service,” 
    47 C.F.R. § 1.9020
    (d)(5); see 
    id.
     §
    1.9030(d)(5) (same); id. § 90.155(d) (similar); id. § 90.685(b)
    12
    (similar); id. § 24.203(a), (b) (similar) — they draw the same
    distinction the Commission drew in the 39 GHz Order and 24
    GHz Order between substantial service and a specific amount of
    construction.
    The fact that, as FiberTower points out, neither the
    regulations nor the rulemakings for the 39 or 24 GHz bands
    include a statement that construction of at least one link is
    required is of no moment. The Commission’s interpretation is
    consistent with the text of the regulations and rulemaking
    records. And courts are to “defer to an agency’s interpretation
    of its regulations, even in a legal brief, unless the interpretation
    is ‘plainly erroneous or inconsistent with the regulation[s]’ or
    there is any other ‘reason to suspect that the interpretation does
    not reflect the agency’s fair and considered judgment on the
    matter in question.” Talk America, Inc. v. Mich. Bell Tel. Co.,
    
    131 S. Ct. 2254
    , 2261 (2011) (quoting Chase Bank USA, N.A. v.
    McCoy, 
    562 U.S. 195
    , 208 (2011) (quoting Auer v. Robbins, 
    519 U.S. 452
    , 461 (1997))); see Rural Cellular Ass’n v. FCC, 
    685 F.3d 1083
    , 1093 (D.C. Cir. 2012). FiberTower has not shown
    that the Commission’s interpretation of the substantial service
    requirement is inconsistent with the regulatory text or the
    original rulemakings.
    B.
    FiberTower also contends that the Commission misapplied
    its substantial service interpretation with respect to forty-two
    license renewal applications. For those licenses, FiberTower
    submitted substantial service showings stating that links had
    been constructed and service was being provided in the license
    area. For example, the substantial service showing for license
    WMF848 stated that “FiberTower so far has one link built and
    operating at a school in Kansas City, Missouri, the geographic
    area of this license.” FiberTower Spectrum Holdings, LLC,
    Substantial Service Showing, FRN 0019211895, at 8 (June 1,
    13
    2012). Neither of the challenged orders indicate an awareness
    of these construction notifications. The Bureau’s substantial
    service analysis was predicated on the finding that there was no
    “construction of any facilities whatsoever” in any of the
    terminated license areas.       Bureau Order, ¶ 22.           The
    Commission, in turn, adopted the Bureau’s conclusion that
    “FiberTower was seeking a finding of substantial service
    without any construction of facilities,” Order, ¶ 38, and acted on
    the basis of its understanding that the Bureau “did not take
    action against any license where construction had been reported,
    whether or not the construction met a safe harbor,” 
    id.
     ¶ 33
    n.133.
    The Commission responds on appeal that FiberTower’s as
    applied challenge is barred because FiberTower failed to present
    this argument to the Commission. FiberTower stated in its
    Application for Review that:
    The Bureau erred as a matter of fact when it found that
    no facilities have been built-out in FiberTower’s
    licensed areas. The record demonstrates that, as of
    June 1, 2012, a significant amount of construction had
    occurred in many of FiberTower’s license areas that the
    Bureau identified for termination.
    Application for Review, at 23. This statement would appear to
    alert the Commission to FiberTower’s claim of factual error, and
    afford the Commission an “opportunity to pass” on the issue, as
    required by § 405(a). It also “concisely” and “plainly” states the
    question for review, as the Commission’s rules require. 
    47 C.F.R. § 1.115
    (b)(1). The Commission points out, not
    unreasonably, that the statement of error in FiberTower’s
    Application for Review was generic and failed to identify the
    specific licenses that FiberTower claims were erroneously
    canceled. After all, FiberTower submitted a large number of
    14
    applications for license renewal with substantial service
    showings, and in seeking Commission review, FiberTower could
    have listed by license number the forty-two license areas in
    which it claimed there had been actual construction. To state the
    obvious, it was in FiberTower’s interest to facilitate the
    Commission’s ability to locate these licenses.
    But the Commission overstates its position in maintaining
    that it “‘had no notice of’ FiberTower’s ‘specific objections.’”
    Appellee’s Br. 39 (quoting U.S. Airwaves, Inc. v. FCC, 
    232 F.3d 227
    , 236 (D.C. Cir. 2000)). The exhaustion cases on which the
    Commission relies involved arguments that had not been made
    at all in the Application for Review or Petition for
    Reconsideration. See Environmentel, LLC v. FCC, 
    661 F.3d 80
    ,
    84 (D.C. Cir. 2011); Qwest Corp. v. FCC, 
    482 F.3d 471
    , 478
    (D.C. Cir. 2007); U.S. Airwaves, 
    232 F.3d at 236
    ; Bartholdi
    Cable, 
    114 F.3d at 279
    . Here, FiberTower alerted the
    Commission to its argument of factual error in the Application
    for Review. Because the Commission requires that substantial
    service showings be made on a license-by-license basis, see
    Order, ¶ 39 n.155, it ill behooves the Commission to imply that
    it can cancel licenses for failure to show any construction
    without reviewing each substantial service showing. To the
    extent the Commission maintains on appeal that the forty-two
    license renewal applications do not adequately demonstrate
    substantial service because they failed to “demonstrat[e] the
    extent of [the constructed] facilities or that those facilities served
    customers or provided internal service,” Appellee’s Br. 39–40,
    that was not the basis on which the Commission denied the
    renewal applications and cannot provide the basis for upholding
    the Commission’s action. See SEC v. Chenery Corp., 
    318 U.S. 80
    , 94 (1943).
    We therefore vacate the Commission’s orders denying
    renewal applications for the forty-two licenses for which
    15
    FiberTower submitted substantial service showings stating there
    had been construction. “An agency action is arbitrary and
    capricious if it rests upon a factual premise that is unsupported
    by substantial evidence.” Ctr. For Auto Safety v. Fed. Highway
    Admin., 
    956 F.2d 309
    , 314 (D.C. Cir. 1992). Upon remand the
    Commission can determine whether there was substantial
    service for those licenses.
    IV.
    FiberTower’s other challenges relate to the denials of its
    requests for an extension or waiver of the substantial service
    deadline beyond June 1, 2012. In view of our conclusion in Part
    III.B, supra, we vacate the orders denying these requests, so that
    the Commission may rule on FiberTower’s requests in light of
    an accurate understanding of the license renewal record.
    Although the burden for challenging the Commission’s denial
    of waiver and extension is heavy, see Morris Commc’ns, Inc. v.
    FCC, 
    566 F.3d 184
    , 188 (D.C. Cir. 2009), the Commission has
    acknowledged that the proportion of licenses that have been
    built out may be relevant to its extension analysis. See Order,
    ¶ 26 (discussing 2 Lightspeed LP, File Nos.
    0005222510–0005222513 (July 23, 2012)).
    Accordingly, we affirm in part and we remand for the
    Commission to determine whether there was substantial service
    for the forty-two licenses in which FiberTower stated there had
    been construction, and to consider anew FiberTower’s requests
    for an extension or waiver of the substantial service requirement
    based on an accurate understanding of the renewal record.
