    Before Wiener, Stewart, and Engelhardt, Circuit Judges.
    Jacques L. Wiener, Jr., Circuit Judge:
    Plaintiff-Appellant Corporativo Grupo R SA DE C.V. (“Grupo R”)
    appeals some of the district court’s findings of fact and conclusions of law
    following a January 2022 bench trial. Grupo R asserts that the district court
    erred by (1) incorrectly interpreting and applying vessel mortgage
    recordation requirements under Panamanian law and (2) recognizing specific
    lien claims by parties who failed to obtain substitute security following the
    judicial sale of a vessel. We AFFIRM.
    I. Factual Background
    In 2008, Intervenors-Appellees Caterpillar Financial Services Asia
    Pte Ltd (“Caterpillar”) and Eksportfinans ASA (“Eksportfinans”) provided
    a loan to Marfield Limited Incorporated (“Marfield”) for the construction
    of an offshore construction vessel named the M/V CABALLO MAYA
    (“MAYA”). To secure payment of this loan, Marfield executed and
    delivered a First Preferred Naval Mortgage to Eksportfinans and a Second
    Preferred Naval Mortgage to Caterpillar on December 19, 2008. As further
    security for outstanding sums owed to Caterpillar, Marfield executed a Third
    Preferred Naval Mortgage on April 17, 2014, encumbering the whole of the
    MAYA. The MAYA was flagged in Panama, so all three of those mortgages
    were submitted to the Panama Maritime Authority Directorate General of
    Public Registry of Property of Vessels (“PMA”), which is the central office
    for the recordation of Panamanian ship mortgages. The PMA reviewed all
    three mortgages twice and accepted them for recordation.
    In 2012, Caterpillar and Intervenor-Appellee the Norwegian
    Government (“Norway”) provided a loan to Shanara Maritime International
    S.A. (“Shanara”) for construction of another offshore construction vessel
    named the M/V CABALLO MARANGO (“MARANGO”). To secure this
    2

    No. 22-20345
    loan, Shanara executed and delivered a First Preferred Naval Mortgage to
    Caterpillar and Norway on February 9, 2012. The following year, KFW
    IPEX-Bank GmbH (“KFW”) provided a loan to Shanara to finance the
    acquisition of cranes for installation aboard the MARANGO. To secure
    payment of this loan, Shanara executed and delivered a Second Preferred
    Naval Mortgage to KFW on January 24, 2013. The MAYA was also flagged
    in Panama, so both mortgages were submitted to the PMA, which reviewed
    the mortgages twice and accepted them for recordation.
    Once construction of the MAYA and MARANGO was completed,
    Marfield and Shanara chartered the vessels to Oceanografia S.A. de C.V.
    (“Oceanografia”) for use in Mexico. The MAYA and the MARANGO were
    chartered there until early 2014, when the Mexican government seized the
    vessels in conjunction with its criminal investigation of Oceanografia. On
    February 28, 2014, Marfield and Shanara terminated their bareboat charters
    of the vessels with Oceanografia, and the vessels remained in the Mexican
    government’s custody. Shanara and Marfield could not generate revenue on
    the vessels and began to fall behind on their loan payments to Intervenors-
    Appellees Caterpillar, Norway, KFW, and Eksportfinans (collectively, the
    “Lenders”). Shortly after that, bankruptcy proceedings were commenced
    against Oceanografia in Mexico, and, on April 10, 2014, the Mexican
    government separately seized the MAYA and MARANGO in connection
    with the bankruptcy.
    In early 2014, Grupo R, a Mexican conglomerate in the oil, gas, and
    energy sector, initiated discussions with Marfield and Shanara to purchase
    the MAYA and MARANGO. On March 21, 2014, the parties entered into
    purchase agreements for the vessels. Shanara and Marfield were
    subsequently unable to obtain the release of the vessels from the Mexican
    government, which violated the deadlines set forth in the purchase
    agreements. Since the agreements are governed by English Law and contain
    3

    a London Maritime Arbitration Association dispute resolution clause, Grupo
    R initiated a London arbitration against Shanara and Marfield. Grupo R
    prevailed, and on May 30, 2019, a London Arbitration Panel entered awards
    of $5,000,000 against Marfield and $5,000,000 against Shanara.
    From the initial arrest of the vessels until December 2017, the Lenders
    executed a number of amendments to the original loan agreements to reaffirm
    Marfield’s and Shanara’s payment obligations, which remained unfulfilled.
    On July 10, 2015, the Lenders, Marfield, and Shanara executed two Standstill
    Agreements in which Shanara and Marfield admitted that their cancellation
    of the Oceanografia charters constituted “materially adverse” events of
    default under their respective loan agreements. To avoid the imposition of
    liens over the MAYA and MARANGO, Caterpillar provided additional
    financing to Marfield and Shanara in the form of four “protective advances,”
    or loans. In return, Marfield and Shanara executed four Preferred Naval
    Mortgages in favor of Caterpillar to secure the outstanding amounts due,
    then registered those mortgages with the PMA. The PMA reviewed each of
    the mortgages twice, then accepted them for recordation. Since 2014,
    Shanara and Marfield have made no loan payments to the Lenders on any of
    the nine mortgages issued.
    II. Proceedings Below
    On May 30, 2019, Grupo R filed suit in the U.S. District Court for the
    Southern District of Texas seeking to attach the MAYA and MARANGO
    under the Texas Civil Practice and Remedies Code Section 61.001, et seq.
    Grupo R requested that the court attach the vessels so they could be sold at
    judicial auction to satisfy Grupo R’s arbitration awards. Grupo R attached a
    Certificate of Ownership and Encumbrance to its Complaint, identifying the
    First, Second, and Third Preferred mortgages over the MAYA and the
    4
    Case: 22-20345          Document: 00516688844              Page: 5   Date Filed: 03/24/2023
    No. 22-20345
    MARANGO. At the time, the MAYA and MARANGO had been released
    from Mexican seizure and were located in Galveston, Texas.
    The district court granted Grupo R’s motion to attach the MAYA and
    MARANGO on June 4, 2019. Shortly thereafter, the Lenders moved to
    intervene in the case to assert their rights, seeking judgment against Marfield
    and Shanara in personam and the MAYA and MARANGO in rem. The
    Lenders caused the vessels to be re-arrested pursuant to Rule C of the
    Supplemental Rules for Admiralty or Maritime Claims and Asset Forfeiture
    Actions. 1 Marfield and Shanara then filed an answer and counterclaim
    against the Lenders for declaratory judgment, fraud, and wrongful arrest.
    On April 22, 2020, the district court ordered the United States
    Marshals Service to put the MAYA and MARANGO up for sale at a judicial
    auction. At the auction, the MAYA was sold to Karadeniz Holding for the
    price of $1,700,000, which the district court confirmed on January 7, 2021.
    Caterpillar, which had been authorized by the court to credit bid the amount
    of its debt, was the successful high bidder on the MARANGO for
    $5,000,000. The court ordered Caterpillar to file a security bond in the
    amount of $4.95 million to confirm the sale of the MARANGO. Caterpillar
    filed the security bond on November 15, 2021, but Grupo R objected to its
    language. Grupo R expressed concern that the security bond would prevent
    Grupo R from collecting against the bond if the Lenders’ mortgages were
    ruled unenforceable against third parties like Grupo R. The district court
    directed Caterpillar to amend the bond in open court to assuage Grupo R’s
    concerns, and the parties executed an amended bond (the “Amended
    Bond”).

    On January 4, 2022, Grupo R, Marfield, and Shanara filed a
    stipulation of various facts, agreeing that the London arbitration awards were
    subject to enforcement and recognition under the New York Convention.
    The district court then entered an order and judgment recognizing and
    confirming the London arbitration awards. With this resolved, the parties
    could proceed to trial.
    On January 18, 2022, a three-day bench trial commenced to determine
    the priority of the Lenders’ foreign ship mortgages and Grupo R’s state-
    created liens, as well as the enforceability of the Lenders’ mortgages. At trial,
    Marfield and Shanara presented testimony from the parties’ corporate
    representatives, while the Lenders and Grupo R presented testimony from
    two Panamanian law experts, Jorge Loaiza for Grupo R, and Margareth
    Mosquera for Lenders. On June 7, 2022, the court issued its findings of fact
    and conclusions of law, holding, in relevant part, that (1) Marfield and
    Shanara are in default under the loan agreements; and (2) the Lenders’
    preferred ship mortgages related to said default outrank Grupo R’s state-
    created liens arising from Grupo R’s attachment of the MAYA and
    MARANGO under Texas state law. Grupo R timely appealed. 2
    III. Standard of Review
    Following a bench trial, the district court’s findings of fact are
    reviewed for clear error and its conclusions of law are reviewed de novo. 3 “So

    Marfield and Shanara are no longer parties to this case because the MAYA and
    MARANGO were sold before trial and final judgment. Marfield and Shanara expressly
    waived the opportunity to file briefs on behalf of those vessels in a letter to this court dated
    November 14, 2022. See Letter from Robert E. Booth in re: Cause No. 22-20345, November

    long as the ‘district court’s account of the evidence is plausible in light of the
    record viewed in its entirety,’ its findings must be affirmed, even if the court
    of appeals might ‘have weighed the evidence differently.’” 4
    The district court’s determination of foreign law pursuant to Rule
    44.1 of the Federal Rules of Civil Procedure is a question of law subject to de
    novo review. 5 When determining an issue of foreign law under Rule 44.1, “the
    court may consider any relevant material or source, including testimony,
    whether or not submitted by a party or admissible under the Federal Rules of
    Evidence.” 6 Although treated as a question of fact at trial, on appeal, “[t]he
    court’s determination must be treated as a ruling on a question of law.” 7
    IV. Discussion
    Grupo R makes two primary arguments on appeal. First, it asserts that
    the district court erred by incorrectly applying and interpreting Panamanian
    law in its determination of the relative priority of the parties’ lien claims.
    Second, Grupo R contends that the district court erred by recognizing
    Caterpillar’s and KFW’s lien claims in connection with the credit sale of the

    MARANGO when they failed to obtain substitute security following the sale.
    These arguments are discussed in turn below.
    A. Relative priority of the Lenders’ mortgages as to Grupo R’s state-
    created liens
    On appeal, the parties dispute whether the Lenders’ liens created by
    the nine ship mortgages take priority over Grupo R’s liens that arose from
    the attachment of the MAYA and MARANGO under Texas state law. The
    relative priorities of the Lenders’ and Grupo R’s rights determine how the
    proceeds from the judicial sale of the MAYA and MARANGO should have
    been allocated. 8 The law of the forum provides the relative rankings of the
    liens, while Panamanian law governs the substance of the liens. 9 The ranking
    of liens in the United States, from highest priority to lowest priority, is as
    follows:
    1. Custodia legis expenses;
    2. Seamen’s liens for wages;
    3. Salvage and general average liens;
    4. Tort liens;
    5. Preferred ship mortgage liens;
    6. Liens for necessaries under CIMLA;
    7. State-created liens that are maritime in nature;
    8. Maritime liens for penalty/forfeiture for violation of
    federal statutes;
    9. Perfected non-maritime liens;
    10. Attachment liens;

    11. Maritime liens in bankruptcy. 10
    “Once competing liens have been ranked according to class, the top priority
    liens will of course be paid first.” 11 Moreover, “[i]f the funds are insufficient
    to pay the next lower ranked class in full, the available funds will be
    distributed among claimants in that class according to rules operating within
    that class.” 12
    Under this ranking regime, Grupo R’s rights are classified as “state-
    created liens that are maritime in nature,” while the Lenders’ liens are
    classified as “preferred ship mortgages.” Grupo R’s liens arose when it
    caused the MAYA and MARANGO to be attached under Texas state law.
    The Lenders’ mortgage liens, on the other hand, arose when Shanara and
    Marfield failed to pay the mortgages over the MAYA and MARANGO,
    which had been executed in Panama and registered with the PMA. 13 The
    Commercial Instruments and Maritime Liens Act (“CIMLA”), 
    46 U.S.C. § 31301
     et seq., defines a preferred ship mortgage as a:
    mortgage . . . established as a security on a foreign vessel if the
    mortgage . . . was executed under the laws of the foreign country under
    whose laws the ownership of the vessel is documented and has been
    registered under those laws in a public register at the port of registry
    of the vessel or at a central office. 14

    The parties do not dispute that the Lenders’ preferred ship mortgage
    liens outrank Grupo R’s state-created maritime attachment liens, and the
    district court confirmed those rankings in its findings of fact and conclusions
    of law. 15 The threshold issue on appeal is whether the Lenders’ mortgages
    are valid and enforceable against third parties like Grupo R, allowing Lenders
    to exercise their priority over the proceeds of the judicial sale of the MAYA
    and MARANGO.
    B. Validity and enforceability of the preferred ship mortgages under
    CIMLA and Panamanian law
    Grupo R and the Lenders agree that CIMLA and Panamanian law are
    implicated in the resolution of this lawsuit. At trial, it was undisputed that (1)
    the Vessels are registered under Panama’s flag; (2) the PMA is the public
    register or central office charged with recording vessel mortgages in Panama;
    and (3) all nine of the Lenders’ mortgages were recorded with the PMA,
    reviewed and accepted by the PMA before their recordation, and reviewed
    again by the PMA when it issued certificates confirming the mortgages’
    compliance with Panamanian law.
    Under CIMLA, “a mortgage on a foreign vessel is preferred so long
    as it was properly (1) executed and (2) recorded under the laws of the nation
    in which the foreign vessel is registered.” 16 For a preferred ship mortgage,
    CIMLA provides a cause of action in federal court “[o]n default of any term
    15
    Grupo R acknowledges the ranking of KFW’s preferred ship mortgage lien in
    relation to its state-created lien but contends that KFW waived its respective “preferred
    ship mortgage” ranking by failing to seek substitute security following Caterpillar’s credit
    bid for the MARANGO. This is a separate issue that is discussed further below.

    of the preferred mortgage.” 17 The mortgagee may bring a civil action or an
    admiralty action in personam against the mortgagor or guarantors to recover
    a deficiency. 18 The mortgagee may also “enforce the preferred mortgage lien
    in a civil action in rem for . . . a foreign vessel.” 19 As noted above, the parties
    agree that each of the Lender’s mortgages was executed in Panama and
    registered with the PMA. Accordingly, the Lenders’ mortgages are properly
    classified as “preferred ship mortgages” under CIMLA.
    The Lenders contend that the inquiry should end here, asserting that
    CIMLA “does not require Lenders to affirmatively establish all facets of
    Panama law before their mortgages can be recognized as preferred ship
    mortgages.” However, Grupo R takes the position that these preferred ship
    mortgages are unenforceable against third parties—such as Grupo R—
    because they fail to meet the substantive requirements for vessel mortgages
    under Panamanian law. This highly technical argument is discussed further
    below.
    The parties agree that Article 260 of Law No. 55 of 2008, the
    Commercial Maritime Law of Panama, governs the substantive mortgage
    recordation requirements under Panamanian law. The Panamanian
    government has apparently not issued an official English translation of the
    full text of Article 260 from the original Spanish version. The parties’
    Panamanian law experts, Loaiza and Mosquera, offered their own competing
    English translations of Article 260 at trial and in their expert declarations.
    Grupo R also pointed out that in 2011, the PMA published a “Merchant

    Marine Circular MMC-11” in English, which refers to Article 260 and
    includes a translation of the mortgage recordation requirements. On appeal,
    the parties dispute the meaning of Article 260’s third clause (“Clause 3”),
    which in its original form states:
    Las fechas de pago del capital o cumplimiento de las
    obligaciones garantizadas e intereses, o la forma de determinar
    dichas fechas, salvo que la hipoteca se haya constituido para
    garantizar obligaciones exigibles a requerimiento, futuras o
    sujetas a condición suspensiva.
    Loaiza’s translation of Clause 3 of Article 260 is as follows:
    Dates of repayment of principal, or for satisfaction of the
    secured obligations, and of interest, or the method to
    determine such dates, unless the mortgage has been granted to
    secure obligations payable on demand, in the future or of
    conditional compliance. (emphasis in original).
    Mosquera’s translation of Clause 3 is as follows:
    The maturity dates of principal or of compliance with the
    guaranteed obligations and interest or the form to determine
    said dates, unless the mortgage is executed as security for
    obligations repayable on demand, obligations subject to
    suspensive condition or future obligations.
    The Merchant Marine Circular MMC-11’s translation of Clause 3 is as
    follows:
    The dates for the payment of the capital of fulfilment of the
    secured obligation and interest, or the method used to
    determine said dates, except if the mortgage is created to
    secure obligation payable on demand, future obligations or
    obligations subject to precedent conditions.
    On appeal, the parties dispute whether the phrase “[l]as fechas de pago del
    capital” in the original version means “loan repayment schedule,” thereby
    requiring each registered mortgage to include a loan repayment schedule.

    Grupo R asserts that all nine of the Lenders’ preferred ship mortgages
    are invalid and unenforceable against third parties because they do not
    include loan repayment schedules or their corresponding payment dates. At
    trial, Loaiza testified that “las fechas” literally translates to the plural phrase
    “the dates,” and that none of the preferred ship mortgages include dates of
    repayment of the loan interest or principal. Loaiza contended at trial that that
    a strict interpretation of Clause 3 is warranted because Article 9 of the
    Panamanian Civil Code states: “[w]hen the meaning of the law is clear, its
    literal word will not be neglected on the pretext of consulting its intent.” 20
    Loaiza asserts that the Lenders improperly attempted to add “maturity date”
    into Clause 3 when the literal translation does not support this. Grupo R
    claims that “[i]f the Panama legislature had intended Article 260, Clause 3 to
    be satisfied by the inclusion of a mortgage’s maturity date alone, they would
    have signaled that by writing the term ‘fecha de vencimiento’ into Clause 3’s
    text.” Relying on Mobile Marine Sales, Ltd. v. M/V Prodromos, 21 a case from
    another circuit, Grupo R contends that the review and certification of the
    nine mortgages by the PMA is of little persuasive significance as to their
    validity.
    The Lenders agree that none of the preferred mortgages include loan
    repayment schedules, but they dispute whether Clause 3 requires such
    schedules at all. Mosquera took issue with Loaiza’s strict interpretation of
    Clause 3, analogizing it to the Spanish translation of the idiom “it’s raining
    cats and dogs.” At trial, Mosquera testified that, although Loaiza’s
    translation of Clause 3 is technically correct, it does not reflect the true
    20
    Loaiza relied on his own English interpretation of Article 9 in support of this
    assertion.

    meaning of Clause 3 under Panamanian law. Mosquera testified that the
    inclusion of the loan maturity dates in each of the preferred ship mortgages
    was sufficient under Clause 3, because “the maturity date is actually the date
    of repayment of the capital and interest of any debt.” Mosquera further
    testified that inclusion of the maturity date is an acceptable and often-used
    way to satisfy the “dates of repayment of principal, or for satisfaction of the
    secured obligations, and of interest, or the method to determine such dates”
    under Clause 3. Mosquera explained that some lenders may choose to include
    a loan repayment schedule, but that most lenders opt to include only the loan
    maturity date.
    The Lenders alternatively contend that Grupo R had actual and
    constructive knowledge of the preferred ship mortgages and has not shown
    that it was prejudiced by the exclusion of loan repayment schedules from the
    preferred ship mortgages. The Lenders point out that Grupo R
    acknowledged that all nine mortgages were recorded with the PMA and
    available for review before initiating this lawsuit. The Lenders also point out
    that that Grupo R attached Certificates of Ownership and Encumbrance for
    the MAYA and MARANGO to the initial complaint, and these certificates
    contained information about the mortgages on the vessels. The Lenders thus
    contend that Grupo R had both actual and constructive knowledge of the
    preferred ship mortgages prior to initiating this lawsuit and that the primary
    purpose of mortgage registration—alerting third parties to the preferred ship
    mortgages—was achieved.

    treated as a question of fact at trial, “[t]he court’s determination [of foreign
    law] must be treated as a ruling on a question of law” on appeal. 23 To deter-
    mine whether a mortgage is valid under foreign law, a court may consider
    “any relevant material or source, including testimony, whether or not sub-
    mitted by a party or admissible under the Federal Rules of Evidence.” 24
    “Courts frequently accept affidavits from foreign-law experts to guide their
    analyses of foreign law.” 25 When there are conflicting opinions offered by
    experts on foreign law, “it is not the credibility of the experts that is at issue,
    it is the persuasive force of the opinions they expressed.” 26
    The district court ultimately held that the Lenders’ preferred ship
    mortgages are valid and enforceable under Panamanian law. The court con-
    sidered testimony from both Loaiza and Mosquera at trial, as well as these
    experts’ corresponding declarations. The court pointed out that Loaiza had
    contributed to the 2019 and 2021 editions of the Maritime Law Desk Hand-
    book, in which he described Clause 3’s requirement as “the terms for the pay-
    ment of principal and interest, or of the maturity date or dates for compli-
    ance of the obligation secured by the mortgage, except in the case of mort-
    gages granted to secure obligations payable on demand, future or conditional
    obligations, when such stipulations are not required.” 27 Acknowledging its

    authority to make determinations of foreign law pursuant to Rule 44.1, the
    court stated that it was “not persuaded that a Panama Maritime Court would
    invalidate [Lenders’] mortgages.” The court explained that “the credibility
    and persuasive force of the opinion of [Lenders’] expert, Margareth Mos-
    quera, are greater than that of Plaintiff’s expert, Jorge Loaiza.”
    The district court directed the allocation of proceeds of the MAYA
    and the MARANGO pursuant to its conclusions regarding the liens’ relative
    priorities. The proceeds from judicial sale of the MAYA were to be allocated
    as follows: (1) $63,243.90 to Grupo R and $663,745.12 to Caterpillar for their
    custodia legis lien claims; and (2) any remaining proceeds to Eksportfinans for
    its First Preferred Vessel Mortgage over the MAYA. The proceeds from the
    credit sale of the MARANGO were to be allocated to Grupo R in the amount
    of $63,243.90 for its custodia legis lien claims, and the remainder of the
    Amended Security Bond released to Norway, KFW, and Caterpillar.
    Here, the district court sufficiently weighed the experts’ competing
    interpretations of Panamanian law and applied the correct meaning of Clause
    3. Both Loaiza and Mosquera are highly experienced and well-credentialed
    experts in the field of Panamanian law, but the persuasive force of Loaiza’s
    testimony was diminished during the district court proceedings. As noted
    above, he admitted to publishing a passage in a well-known maritime law
    treatise in which he endorsed Mosquera’s proposed interpretation of Clause
    3. During trial, Loaiza testified that this interpretation of Clause 3 only

    of the treatise.

    applies to mortgages that are payable on demand or call for a single “balloon”
    payment, but he does not offer any evidentiary support for this position.
    When considered together, Loaiza’s, Mosquera’s, and the PMA’s
    translations of Clause 3 do not appear to preclude enforceability solely
    because a loan repayment schedule was omitted. Grupo R’s position appears
    to ignore the phrase “o cumplimiento de las obligaciones garantizadas e
    intereses,” or, as Loaiza translated it, “or for satisfaction of the secured
    obligations.” According to Mosquera, the PMA and Panamanian attorneys
    interpret this phrase to mean “maturity date.” Thus, it appears that there
    are two different avenues to achieve compliance with Clause 3: provide a loan
    repayment schedule or provide the maturity date of the loan in question.
    We are also not convinced that compliance with Article 260’s highly
    technical requirements is dispositive in this case. We previously held that it
    is “well established that the validity of a mortgage is dependent only on the
    existence of a debt actually secured by the mortgage and not on the
    description of the debt contained in the instrument.” 28 Further, other
    circuits have explained that foreign law plays a more limited role in
    determining the validity and enforceability of foreign mortgages under
    CIMLA. 29 In M/V Prodromos, the Third Circuit explained that “the stringent
    procedural requirements for perfecting domestic ship mortgages are not

    imposed on foreign ship mortgages . . . to provide a simplified procedure for
    enforcing mortgages without destroying substantive rights.” 30 In fact, Grupo
    R’s heavy reliance on M/V Prodromos appears to work against it because the
    Third Circuit ultimately held that the mortgagees’ failure to include a
    technical requirement—the vessel’s navigation license number—did not
    render the mortgage invalid under Panamanian law. 31
    We conclude that the district court correctly held that the nine
    preferred ship mortgages at issue are enforceable under CIMLA and
    Panamanian law, and that the Lenders’ preferred ship mortgage liens enjoy
    priority over Grupo R’s state-created maritime attachment liens.
    C. Whether Caterpillar and KFW waived their respective lien
    positions in relation to the credit sale of the MARANGO
    Grupo R’s second primary contention on appeal is that KFW and
    Caterpillar waived their respective lien positions in relation to the judicial
    sales of the MAYA and the MARANGO. Grupo R asserts that “Caterpillar
    made use of a procedural tactic that allowed it to purchase the MARANGO
    via credit bid, such that no actual monies were provided.” Grupo R claims
    that this provided an unfair benefit to Caterpillar because it was never
    required to exchange or place any money in the court’s registry to stand as
    the res, or substitute security, for the MARANGO after the sale. Grupo R
    asserts that, by failing to seek substitute security, KFW forfeited its in rem

    lien claim against the MARANGO, and that Caterpillar forfeited its custodia
    legis claim against the MARANGO.
    Grupo R claims that, by moving for substitute security following the
    MARANGO’s credit sale, it was the only party to preserve its lien claims.
    Grupo R insists that the Amended Security Bond responded only to Grupo
    R’s claims and made no exception for Caterpillar’s custodia legis costs, which
    arose as a separate claim. Grupo R claims that, as a result, Caterpillar was not
    entitled to reduce the Amended Security Bond by the amount of its custodia
    legis lien claim. Grupo R further contends that any judgment KFW may now
    possess exists solely in personam against Shanara, as it no longer has a valid
    lien claim against the Amended Security Bond.
    The Lenders counter that it would be absurd to require Caterpillar to
    lodge security for its own custodia legis claim. Moreover, the Lenders contend
    that KFW’s claim against the MARANGO is subject to a stipulation of pay-
    ment amounts between Caterpillar and KFW under an intercreditor agree-
    ment, obviating the need for substitute security. In support, the Lenders ref-
    erence Rule E(5)(a) of the Supplemental Rules for Admiralty or Maritime
    Claims, which states that “[w]henever process of maritime attachment and
    garnishment or process in rem is issued the execution of such process shall be
    stayed, or the property released, on the giving of security, to be approved by
    the court or clerk, or by stipulation of the parties.” 32
    The district court agreed with the Lenders, holding that their inter-
    pretation of Supplemental Rule E(5)(a) was correct. The court further held
    that the intercreditor agreement containing a stipulation of payment between
    KFW and Caterpillar was sufficient to secure KFW’s lien claim against the
    MARANGO. That court likened the stipulation to a “letter of undertaking,”

    which “is customary in the maritime industry” and “is the functional equiv-
    alent of a bond for the purpose of securing a claim against a vessel.” The
    district court also noted that Grupo R did not offer any authority for its as-
    sertion that a secured creditor’s failure to seek substitute security constitutes
    lien claim forfeiture.
    We perceive no merit in Grupo R’s alternative arguments and there-
    fore affirm for the same reasons provided by the district court.
    V. Conclusion
    For the reasons detailed above, we AFFIRM the district court’s
    findings of fact and conclusions of law with regard to (1) the validity,
    enforceability, and relative priority of the parties’ liens following the judicial
    sale of the MAYA and MARANGO, and (2) the status of Caterpillar’s and
    KFW’s lien positions following the credit sale of the MARANGO.
