    Appellees.
    Appeal from the United States Bankruptcy Court
    for the District of Colorado
    Before CORNISH, NUGENT, and SOMERS, Bankruptcy Judges.
    SOMERS, Bankruptcy Judge.
    This case involves an objection by creditor and appellee, First Citizens Bank
    & Trust Co. (“Bank”), to certain debts that the debtor, Matthew Edward Autterson
    (“Autterson”), scheduled as uncontested claims of appellants GL3B Trust II (the
    “Trust”) and GL3B Partners Limited, LLP (the “Partnership”). Autterson created
    and controlled both the Trust and the Partnership at all relevant times, and

    precedential, except under the doctrines of law of the case, claim preclusion, and
    issue preclusion. 10th Cir. BAP L.R. 8018-6.
    Autterson joined in the defense of the claims. The Bank objected that the claims
    had been scheduled and would be allowed for more than Autterson actually owed,
    to the prejudice of the other unsecured creditors. Following a two-day trial, the
    bankruptcy court granted the Bank’s objection, in part, allowing but reducing the
    amount of the Trust and Partnership claims by approximately 26%.
    I.     BACKGROUND
    In 2001, Autterson was a sophisticated and successful businessman who had
    just sold a trust company for a substantial profit. He hired a number of advisors to
    help him manage his accumulated assets in such a way as to minimize the impact
    of income and estate taxes on them. As a result of his tax and estate planning,
    Autterson created various legal entities, including both the Partnership and the
    Trust. The Partnership was created in October 2001 as a Colorado limited liability
    partnership. 1 Autterson has always acted as the Partnership’s general and
    managing partner, though the partnership agreement was amended in 2013 to make
    the Trust an additional general partner. 2 The Partnership’s limited partners as of
    the petition date were GL3B Trust I and GL3B GRAT, both of which are also
    controlled by Autterson. 3
    As noted by the bankruptcy court, each of the Autterson entities maintained
    separate legal identities since their inception and have satisfied the standards for
    treatment as such. Moreover, Autterson’s dealings with these entities have always
    been carefully and appropriately documented, and money transfers from the
    Partnership and Trust to Autterson have always been treated as loans. Based on

    Autterson’s brother, Mark Autterson, is the designated trustee of
    Autterson’s two trust entities, GL3B Trust I and GL3B Trust II (the appellants in
    this case). However, there was no dispute at trial that the trust entities were
    “controlled” by Autterson.
    -2-
    this course of dealing, the bankruptcy court concluded, as do we, that the
    Partnership and Trust loans to Autterson are legitimate unsecured debts, entitled to
    be treated as such in Autterson’s bankruptcy case. But what Autterson owed on
    these obligations as a matter of non-bankruptcy law is another matter. 4 The Trust
    and the Partnerships attempted to “gross up” their claims by strictly enforcing note
    terms that the debtor (who controlled the entities) routinely disregarded. The terms
    of the agreements cannot be enforced or disregarded by the “parties” according to
    their convenience, especially when doing so places the debtor’s other unsecured
    creditors at a disadvantage.
    A.    The Trust Note
    In 2003, Autterson borrowed $2 million from the Partnership. The
    promissory note given to the Partnership by Autterson in return for the loan
    provided for repayment in fifteen equal payments of approximately $206,000,
    beginning in 2004 and continuing through 2018, annually. The note provided for
    interest on the principal in the amount of 6.00%, compounded annually, and a
    default rate of 12.00%, to be imposed on the date of a default. 5 In 2006, the
    Partnership divided up this debt and distributed it to its partners, pro rata, based on
    each partner’s percentage interest in the Partnership.
    The amount of the debt at the time of division was $2,336,595, including
    accrued but unpaid non-default interest. 6 Despite the loan’s default status at that
    time, the divided sum did not include any default interest. The partners’ shares
    were: (1) $530,314 to Autterson (22.7%); (2) $894,121 to GL3B GRAT (38.3%);

    executed, in January 2006, Autterson should have made the May 2004 and May
    2005 payments. His failure to do so was an “Event of Default” under the terms of
    the underlying note, the occurrence of which triggered imposition of the default
    interest rate.

    (3) $254,806 to GL3B Trust I (10.9%); and (4) $657,354 to the Trust (28.1%). The
    amount designated to go to Autterson was immediately cancelled. 7 Also, the
    amount designated to the GL3B Trust I was used to offset an even larger amount
    owed by that entity to Autterson. 8 Thus, only the GL3B GRAT and Trust portions
    remained post-division.
    Autterson signed a note for the Trust’s portion of the debt (the “2006 Note”
    or the “Trust Note”), which is one of the three claims at issue in this appeal. The
    2006 Note carried a non-default interest rate of 4.48%, which accrued annually,
    and a 12% default interest rate. The note terms specified that all principal and
    interest became due and payable in full on January 15, 2015. 9 Prepayments of
    principal could be made at any time, without penalty, and any prepayments would
    be applied first to accrued interest and then to principal. Autterson made a total of
    fourteen payments attributed to the 2006 Note, beginning approximately four
    months after its issuance, and ending in December 2013. 10 For each year from
    2006 to 2010, these twice-yearly prepayments totaled $9,380. 11 In 2011 through
    2013, Autterson made annual payments in the amount of $4,460 each.
    In his bankruptcy schedules, Autterson listed the 2006 Note as an
    uncontested debt in the amount of $933,393. At trial, the Trust claimed
    $857,648.60 was due on the 2006 Note as of the date Autterson filed his petition.
    However, the bankruptcy court concluded that, as the Trust had failed to prove

    See Trial Ex., 5 in Appx at 101-03. Because no payments were required by
    the terms of the 2006 Note until 2015, that note was the only one of the three
    notes at issue in this appeal that was not in default when Autterson filed his
    petition.

    entitlement to any interest on the 2006 Note principal, its claim was allowed for
    principal only, in the amount of $597,074.
    B.       The Partnership Notes
    1.   The 2008 Note
    The Partnership held two promissory notes from Autterson when he filed his
    petition. The first was executed in 2008 (the “2008 Note”) and was in exchange
    for Autterson’s purchase of a residence owned by the Partnership. The home,
    located on Radcliffe Avenue, in Cherry Hills Village, Colorado (the “Residence”),
    was purchased by the Partnership in June 2005 for $1,875,000. 12 Autterson moved
    into the Residence within a few months of the Partnership’s 2005 purchase of it,
    and lived there rent and mortgage free until he purchased it from the Partnership in
    2008. 13 According to Autterson, he purchased the Residence in 2008, based on his
    counsel’s recommendation that he either pay rent or purchase the property so that
    his use of it would be considered a bona fide “arm’s length” transaction between
    related parties. 14 Autterson was required by a divorce settlement to pay his ex-
    wife’s mortgage on her home, and decided to pay off that mortgage rather than
    making payments on it. In order to obtain the $1.25 million loan needed to do so,
    Autterson would have to provide that lender with collateral, which meant he
    needed to take ownership of the Residence. 15

    also spent approximately $350,000 on improvements to the Residence between its
    purchase in 2005 and its sale to Autterson in 2008. Trans. 1, 54-55 in Appx at

    . As the Partnership did not secure the 2008 Note with a
    mortgage on the Residence, Autterson had its entire value available to use as
    collateral for other loans.
    -5-
    The face, or principal, amount of the 2008 Note was $2,219,359.19, and it
    carried a 2.87% non-default interest rate, and a 12% default rate. 16 Interest was to
    accrue and be paid annually on the first eight anniversaries of its execution, and
    principal was to be repaid in full on the day before the ninth anniversary. 17
    Autterson paid the accrued interest, in the amount of $63,695.61, on the first
    anniversary of the 2008 Note, which was in April 2009. 18 However, he paid only
    approximately 25% of the accrued interest in 2010, the second anniversary of the
    2008 Note, and made no payments on it after that. 19
    In his bankruptcy schedules, Autterson listed the 2008 Note as an
    uncontested debt. At trial, the Partnership claimed $3,449,340 was due on the
    2008 Note as of the date Autterson filed his petition. 18 However, the bankruptcy
    court concluded that the Partnership had failed to prove entitlement to default
    interest under the 2008 Note and allowed the Partnership’s claim, including
    principal and non-default interest, in the amount of $2,517,299.68.
    2.     The 2010 Note
    The second note from Autterson to the Partnership was executed in April
    2010 (the “2010 Note” and, together with the 2008 Note, the “Partnership Notes”).
    The 2010 Note had a face value of $500,000, and was given in exchange for a
    number of advances made to Autterson by the Partnership, both before and after
    the note was executed. 19 The 2010 Note carried a 2.7% non-default interest rate, a
    12% default rate, and included the same nine anniversary payment terms as the
    16

    In fact, the advances already made by the Partnership to Autterson prior to
    his execution of the 2010 Note were well in excess of that Note’s face value.

    2008 Note. 20 Approximately three months after the 2010 Note was signed,
    Autterson paid the Partnership $466,123.19 on the 2010 Note, using proceeds from
    his sale of the Residence to third parties. 21 Previously, Autterson had purchased a
    new residence, located on Lafayette Street in Cherry Hills Village (the “Lafayette
    House”), which he listed on a September 30, 2010 personal financial statement as
    having a value of $3.7 million and a mortgage of more than $2.53 million. 22 The
    Partnership made a total of thirteen advances, from April 1, 2010 to December 6,
    2013, to Autterson that were included in the principal balance of the 2010 Note. 23
    The advances totaled $1,955,000. 24 The first of those advances, in the amount of
    $1,050,000 was for a down payment on the Lafayette House. 25 Approximately
    $400,000 of the advances were used by Autterson to modify an outstanding loan to
    various Communicom entities, for which Autterson was a guarantor. 26 The
    remaining proceeds were spent on capital improvements to the Lafayette House. 27
    Autterson filed his Chapter 11 bankruptcy petition on December 9, 2013. In
    his schedules, he listed $5,850,000 as an uncontested total amount due under the
    Partnership Notes. At trial, the Partnership claimed $1,907,193.33 was owed on

    the 2010 Note, for a lesser total of $5,356,533.33 for both Partnership Notes. 28 The
    bankruptcy court determined that the 2010 Note was effectively “an open account
    advance line of credit where [the Partnership] failed to prove that it is owed
    interest.” 29 The bankruptcy court allowed the Partnership’s claim on the 2010 Note
    in the amount of $1,488,876.81, consisting of all advances, less Autterson’s one
    payment.
    II.    APPELLATE JURISDICTION
    This Court has jurisdiction to hear timely filed appeals from “final
    judgments, orders, and decrees” of bankruptcy courts within the Tenth Circuit,
    unless one of the parties elects to have the district court hear the appeal. 30 The
    bankruptcy court’s orders on appellants’ claims, as well as its judgment on those
    orders, were entered on November 18, 2014, and an order establishing the amount
    of a claim against the bankruptcy estate is final for purposes of appeal. 31
    Appellants timely filed their notices of appeal on December 1, 2014, and no party
    elected to have the appeal heard by the district court. 32 Therefore, this Court has
    valid appellate jurisdiction.

    Our discussion of this issue involves the applicability of the concepts of
    waiver and parol evidence. These concepts require that both factual and legal
    issues be considered. A conclusion regarding applicability of the parol evidence
    rule is primarily a legal issue that is reviewed on appeal de novo. 33 However,
    waiver is primarily a factual issue that is reviewed for clear error. 34
    IV.    DISCUSSION
    A.     Bankruptcy Court Ruling
    Although the bankruptcy court did an excellent job of pulling the evidence
    presented at trial into an understandable narrative, it did not express a specific
    legal rationale for its legal conclusions. Nonetheless, this Court believes that the
    basis for the bankruptcy court’s ruling may be gleaned from its oral findings and,
    even if not, an appellate court may affirm a trial court’s decision on any basis that
    is supported by the record. 35 The bankruptcy court’s ruling repeatedly emphasized
    the parties’ “course of conduct.” The conduct the court described, which was all
    subsequent to execution of each Note, established that the parties repeatedly
    ignored the express terms of the Notes over the course of several years. Such
    conduct may be determined to be a waiver of those terms, whether or not the
    bankruptcy court used that specific term. Thus, this Court interprets the
    bankruptcy court’s fact findings to establish that the parties’ course of conduct
    with respect to each Note indicated that strict compliance with the Notes’
    provisions would not be enforced. Specifically, the Partnership waived its right to
    charge default interest on the 2008 and 2010 Notes, and failed to prove its claim
    for non-default interest under the 2010 Note. The Trust, which was not entitled to

    default interest on the 2006 Note since payment on that Note was not due until
    after Autterson filed his bankruptcy petition, similarly failed to prove its claim for
    non-default interest.
    B.     Waiver
    It is well established that contract rights may be waived. 36 In Colorado, the
    elements necessary to effect a waiver of contract terms are:
    In general, a party may waive a contract provision where the party is
    entitled to assert a particular right, knows the right exists, but
    intentionally abandons that right. Waiver may be express or implied,
    such as when a party engages in conduct which manifests an intent to
    relinquish37the right or privilege, or acts inconsistently with its
    assertion.
    Moreover, the Colorado Court of Appeals has held that a written contract may be
    modified by oral agreement, even if the contract expressly forbids such
    modifications. 38 That court also held that:
    [A]n express provision in a written agreement may be waived, either
    expressly or by implication. Such a waiver may be implied if a party
    engages in conduct which manifests an intent to relinquish the right or
    privilege or acts inconsistently with   its assertion. And, the question of
    waiver is a question of fact . . . . 39
    Conduct that implies a waiver must be clear and unambiguous in order to be
    effective:
    Waiver is the intentional relinquishment of a known right or privilege.
    A waiver may be explicit, as when a party orally or in writing
    abandons an existing right or privilege; or it may be implied, as, for
    example, when a party engages in conduct which manifests an intent
    to relinquish the right or privilege, or acts inconsistently with its
    assertion. Although an intent to waive a benefit may be implied by

    conduct, the conduct itself should be free from ambiguity and clearly
    manifest the intention not to assert the benefit. 40
    These concepts apply to the present facts. As Autterson is both the borrower
    and his lenders’ representative, no communication whatsoever between the
    “parties” was the norm. Autterson, when acting on behalf of the Partnership or the
    Trust, did not issue default notifications to himself, nor did he directly express an
    intent to waive the Notes’ provisions. Instead, after signing standard agreements
    on behalf of both parties, he simply paid or did not pay his obligations as he saw
    fit. In fact, Autterson claimed not even to realize that the Partnership Notes were
    in default until he was preparing to file his personal bankruptcy. 41 Nonetheless, his
    conduct on both sides of the transactions can hardly be interpreted in any other
    way than as a waiver of the express terms of the written agreements. Autterson
    paid interest only if, and when, it suited his interests.
    The bankruptcy court emphasized the inter-relatedness of Autterson and the
    Partnership and Trust in its ruling, stating:
    While the trust and partnership have maintained their separate formal
    legal identities for many years they have both been fully controlled by
    Mr. Autterson. They have both engaged in transactions with him,
    involving substantial dollars in property which could not be
    characterized as arms’ length. Several transactions involve Mr.
    Autterson calling the tune on both sides of the table, having little
    resemblance to transactions where each side of the deal is looking out
    for its own interests. . . . The partnership advanced funds to Mr.
    Autterson  with little regard to his capacity or intent to repay the
    funds. 42
    This unity of interest between the parties is precisely why the Bank objected to the
    Partnership and Trust claims, arguing the advances to Autterson were equity
    payments due to lack of any creditor/debtor relationship. Although the bankruptcy

    court at least partially agreed with this sentiment, it nonetheless refused to
    invalidate any of the principal of the Notes, stating:
    The evidence of the parties’ course of dealings carries the day. The
    Court concludes that the trust and the partnership claims are in fact
    debts of this Debtor. They have never been treated otherwise. The
    non-arm's length dealings of affiliates does not itself mean that the
    debt should be treated as equity where the formalities  of a
    debtor/creditor relationship have been honored. 43
    This conclusion, from which the Bank did not appeal, resulted in an award in
    excess of $9 million to the Partnership and Trust. Had the bankruptcy court
    concluded that the unity of interest between the parties rendered their agreements
    illusory and unenforceable, there would have been no award of principal at all.
    Instead, the bankruptcy court determined the Notes’ interest terms were ambiguous
    and, therefore, subject to interpretation in light of the parties’ conduct.      The
    Colorado Court of Appeals has affirmed a trial court’s refusal to award pre-
    judgment interest on the amount due under a promissory note, using the doctrine of
    waiver, stating:
    Waiver of a contract term occurs when a party to the contract is
    entitled to assert a particular right, knows the right exists, but
    intentionally abandons that right.
    Here, although the promissory note called for interest at the rate
    of ten percent per annum, [creditor’s] internal records showed that all
    of the [borrower’s] payments were credited to principal. And, all of
    the statements [creditor] sent indicated that only a principal balance
    was due. Moreover, when the deed of trust was executed, the amount
    due reflected that all credits for payments made had been applied to
    principal, and no claim for interest was then made. In our view,
    evidence of these actions supports the trial court’s finding that
    [creditor] waived its right to collect the prejudgment interest to which
    it otherwise would have been entitled. 44

    The factual findings the bankruptcy court made regarding intent to waive
    interest are supported by the record on appeal. 45 Some of the evidence the court
    relied on included: (1) the 2006 Note represents the Trust’s pro rata share of a
    previous debt owed by Autterson to the Partnership, including only regular accrued
    interest, even though the previous loan was in default at the time and therefore
    subject to default rate interest; (2) Autterson prepared several financial statements
    for the Bank and others that suggest he considered the amounts due under the
    Partnership and Trust Notes did not include interest; 46 (3) Michael Winterscheidt,
    the accountant for Autterson, the Trust, and the Partnership, did not calculate the
    amounts due under the Notes until Autterson was preparing to file bankruptcy; (4)
    Mr. Winterscheidt inflated the amounts Autterson owed by prematurely triggering
    interest accrual whenever a payment was made so that the payment would be
    applied to interest rather than principal, which violated the Notes’ provisions that
    principal could be prepaid without penalty and that interest only accrued annually;
    (5) default interest had not been charged on the Partnership Notes despite their
    having been in default for years; (6) although the 2006 Note did not require
    payment until 2015, advances Autterson made to fund the Trust’s annual life
    insurance premiums were credited to that Note, but only in preparation for
    Autterson’s bankruptcy filings; (7) the face value of the 2010 Note bore no
    relationship to the amounts advanced to Autterson up to its execution; and (8) in
    45
    An appellate court must review trial findings in a light most favorable to
    the prevailing party and, when trial was to the court rather than a jury, those
    findings are “presumptively correct.” Cowles v. Dow Keith Oil & Gas, Inc., 
    752 F.2d 508
    , 510-11 (10th Cir. 1985).
    46
    Appellants argued at trial that Autterson’s personal financial statements
    should not bind the Trust or Partnership. In the view of the bankruptcy court, that
    argument was “too cute.” We agree. Where an individual completely controls a
    business entity, particularly ones he established and funded, the line between
    individual and business identities is blurred. Autterson acted at all times in a
    manner he deemed beneficial to himself and his related entities. We see no
    reason to differentiate between his personal and his business conduct when even
    he did not do so.
    -13-
    general, the parties did not act as if the terms of the notes controlled their dealings.
    From these and other facts, the court concluded that “the parties’ course of dealing
    [regarding the 2010 Note was] so far removed from the [N]ote terms, that the
    [N]ote itself reveals little or nothing about what is owed.” 47
    The bankruptcy court found only with respect to the Partnership’s 2008 Note
    related to sale of the Residence did the parties’ course of dealing “bear[] any
    resemblance to the terms of the note.” However, as no default interest was charged
    on that loan despite Autterson’s repeated failures to make the required payments,
    the court determined that the balance due on that note did not include default rate
    interest. Thus, the allowable amount of the claim based on the 2010 Note was
    calculated by simply subtracting applied payments from the relevant advances.
    Finally, the bankruptcy court denied all interest on the 2006 Note, finding both that
    “not a single interest payment was made in accordance with the note’s terms in
    over six years,” and that the trustee, Autterson’s brother, didn’t even know how to
    treat the payments that were made. 48 Thus, the claim based on the 2006 Note was
    also allowed in the amount of principal minus credits for insurance premium
    payments made by Autterson.
    In its brief on appeal, Bank asserts, apparently for the first time, that the
    parties “modified” the Notes’ interest provisions through their conduct. Appellants
    assert that the Bank’s failure to rely on the legal concept of contract modification
    in the bankruptcy court, together with the bankruptcy court’s failure to expressly
    base its decision on that ground, should preclude this Court’s consideration of that
    issue as well. However, since an appellate court may affirm on an entirely
    different basis than the one relied on by the bankruptcy court, the principle that an
    argument not made in the trial court may not be made on appeal typically applies
    47

    only to appellants. 49 Thus, appellate courts are not at liberty to reverse on grounds
    not presented to the trial court, with the exception of lack of subject matter
    jurisdiction. 50 In any event, this Court’s decision is based on waiver rather than
    modification.
    Besides arguing that the modification issue should not be considered on
    appeal, appellants attack applicability of modification to the facts on several
    grounds. First, they deny that any of the conduct in which they engaged can be
    considered “clear and unambiguous” evidence of intent to waive interest. 51 This
    denial is self-serving and of little weight. The bankruptcy court considered many
    facts to support an inference that interest, particularly default interest, would not
    be charged. The fact that Autterson claims he “didn’t know” he was in default on
    the Notes until preparing his filings for bankruptcy is fairly compelling evidence
    that no one was treating the express terms of the Notes as binding. Autterson’s
    testimony to the effect that he always intended to repay the Notes, and that neither
    the Trust nor the Partnership ever waived interest, does not outweigh the fact that
    interest was never charged. 52
    Appellants also assert that a contract modification requires additional
    consideration, and none was forthcoming from Autterson that would support the
    waiver of interest by the Note holders. Thus, the concepts of contract waiver,
    modification, and estoppel with respect to agreements are related and somewhat
    intertwined, and may sometimes, but not always, be used interchangeably. Relying

    on Corbin on Contracts, the New Mexico Supreme Court clarified the distinctions
    between the concepts, stating:
    The law of waiver as discussed by Professor Corbin and our own cases
    suggests several possible situations: (1) actual waiver, either express
    or implied in fact, not supported by consideration, which may be
    retracted in the absence of detrimental reliance; (2) modification,
    which is not subject to retraction, based upon mutual agreement to
    waive certain obligations or conditions and the exchange of
    consideration; or (3) waiver by estoppel based upon either an actual
    waiver or certain “expressions or conduct” where the reliance of the
    opposite party and his change of position  justifies the inhibition to
    assert the obligation or condition. 53
    What the record before this Court demonstrates is waiver by the Partnership and
    the Trust of their respective rights to hold Autterson in default and to charge him
    interest on his loans. According to Professor Corbin, waiver of a contractual right
    requires no additional consideration. In Colorado, waiver of a default “may be
    shown by accepting payment after default, by accepting payment after giving
    notice of an election to accelerate, or by mere inaction.” 54
    In this case, each of the Notes included the following terms:
    Default. An event of default (“Event of Default”) shall occur if
    Borrower fails to make any principal or interest payment when due.
    Upon the occurrence of an Event of Default, interest shall be payable
    at a rate of 12% per annum from the date of the Event of Default. . . .
    Miscellaneous. (a) Presentment, 55notice of dishonor, and protest are
    hereby waived by Borrower . . . .
    Although the Notes neither required the Partnership or the Trust to declare a
    default nor to exercise an option to apply default interest, that does not rule out
    waiver of the default interest provision. Nor does lack of additional consideration
    preclude waiver.

    None of the Notes in this case were ever declared to be in default, nor was
    Autterson ever directed to make missed payments. The terms of each of the Notes
    were ignored until Autterson was preparing his bankruptcy filings. For example,
    the 2006 Note did not require scheduled payments, but payment in full was
    required on or before January 15, 2015. In preparation for bankruptcy, Autterson
    asked his accountant (who was also the accountant for both the Trust and the
    Partnership) to determine what was owed on each Note. The accountant applied all
    of Autterson’s life insurance payments to the 2006 Note, even though no payments
    were due on that Note. In fact, the accountant applied insurance premium
    payments made after April 1, 2010 (when the 2008 Note was technically in
    default), as credits to the 2006 Note. Similarly, the 2010 Note was technically in
    default as of April 1, 2011, yet the Partnership continued to advance significant
    amounts of money on that Note until December 2013, shortly before Autterson
    filed his bankruptcy petition. This fact led the bankruptcy court to note that the
    Partnership had “advanced funds to Mr. Autterson with little regard to his capacity
    or intent to repay the funds.” 56 We agree.
    Each of these transactions was effectuated on behalf of both parties by
    Autterson, and only documented by the Notes themselves. Few actual payments
    were made in accordance with the terms of the Notes, and what were construed to
    be payments were not actually “applied” to a particular Note until it suited
    Autterson’s needs to do so. Autterson was always aware of the implications of his
    transactions, as well as the effect of his impending bankruptcy on both himself and
    his wholly-controlled entities. Only when preparing his bankruptcy filings, he
    asserts, did he even realize the 2008 and 2010 Notes were in default, yet he assured
    the bankruptcy court on behalf of the Partnership and the Trust that “they” never
    waived his defaults or had any intention of not charging him interest. This is
    56
    Ruling Trans., 8 in Appx at 1332.
    -17-
    patently without merit. Being on all sides of these transactions, Autterson must be
    charged with knowledge of the terms of the Notes, that he had made or missed
    payments, and of the events and effects of default on both obligor and obligee. He
    chose not to make required payments and to forego the enforcement of penalties.
    Indeed, he chose to keep advancing Partnership funds to himself with full
    knowledge that the Note under which the advances accrued was already in default.
    He cannot now avoid the consequences of his conduct by simply asserting that he
    didn’t know. His conduct, on his own behalf and on behalf of his entities, plainly
    and definitively indicates that there was no intention to enforce the default
    provisions of the Notes. In addition, Autterson’s decision to ignore the terms of
    the 2006 and 2010 Notes for years made it impossible for the Trust and the
    Partnership to prove a case for interest at all. There was no contemporaneous
    application of credits, no payments that corresponded to the terms of the Notes,
    and clearly no intent to do more than simply repay the principal on those Notes.
    Autterson did not even calculate or indicate the interest that was owed on the Notes
    for his personal financial statements. We therefore conclude that the appellate
    record supports the bankruptcy court’s decision to disallow the interest portion of
    the obligees’ claims.
    C.    Parol Evidence Rule
    Appellants assert that the bankruptcy court violated the parol evidence rule
    by finding the Notes’ terms to be ambiguous, and then considering the parties’
    conduct in order to determine their intent with respect the contract terms. The
    parol evidence rule provides that extrinsic (or “parol”) evidence may not be used to
    interpret the intent of a written agreement unless the agreement is “ambiguous.” 57
    57
    See, e.g., Gagne v. Gagne, 
    338 P.3d 1152
    , 1163 (Colo. App. 2014)
    (extraneous evidence may only be admitted to prove intent when there are
    ambiguous contract terms); Gorsuch, Ltd., B.C. v. Wells Fargo Nat. Bank Ass’n,
    
    771 F.3d 1230
    , 1238 (10th Cir. 2014) (courts may only consider extrinsic
    (continued...)
    -18-
    Thus, clear and unambiguous contract terms may not be altered by evidence that
    suggests a different intent. The rule, however, only excludes evidence of “prior or
    contemporaneous oral agreements,” and therefore, does not alter the long-standing
    rule that parties may waive or alter the terms of their agreements by their conduct
    after the agreement is in place. 58 Thus, the parol evidence rule does not apply to
    evidence that establishes “a modification or termination of even an integrated
    agreement.” 59
    Although the bankruptcy court did determine the Partnership and Trust Note
    terms to be ambiguous, it did so only in disagreement with testimony by
    appellants’ accountant to the effect that he had calculated the amounts due on each
    Note as “prescribed by the clear and unambiguous terms” of the Notes. 60 The court
    simply disagreed. It did not rule that the parol evidence rule was inapplicable, nor
    did it consider prior or contemporaneous evidence to determine the parties’ intent
    when the Notes were executed. Rather, it considered conduct subsequent to
    execution of the Notes in reaching the conclusion that, whatever the parties’ initial
    intent had been, strict compliance with the Notes’ terms would not be enforced.

    effect is to add to, vary, modify, or contradict the terms of a writing which the
    parties intend to be a final, complete, and exclusive statement of their
    agreement.”).

    default interest would not be applied, that conduct indicated an intent to waive
    provisions of the Notes to which they had previously agreed. In addition, their
    conduct indicated that application of any interest under any Note would be decided
    on a case-by-case (or note-by-note) basis. As this decision has already discussed,
    the bankruptcy court’s findings with respect to intent are supported by the evidence
    and, are therefore, not clearly erroneous. Moreover, consideration of conduct
    subsequent to execution of an agreement to determine intent at that time does not
    violate the parol evidence rule. 58
    V.     CONCLUSION
    The record supports a finding that the interest provisions of the Trust and
    Partnership Notes were intentionally waived by the parties’ conduct subsequent to
    execution of the Notes. Therefore, the bankruptcy court’s reduction of interest
    allowed under the Notes is AFFIRMED.
