    ZAGER, Justice.
    In this interlocutory appeal, we are asked to determine whether the
    district court properly denied the bank’s two motions for summary
    judgment.   The plaintiffs filed a multiple-count consumer class action
    lawsuit against the bank challenging the one-time nonsufficient funds
    (NSF) fees it charged when the plaintiffs used their debit cards to create
    overdrafts in their checking account. For the reasons set forth below, we
    find that the district court erred in denying the motions for summary
    judgment except as to the good-faith claim involving the sequencing of
    the overdrafts.   The decision of the district court is affirmed in part,
    reversed in part, and remanded for further proceedings.
    I. Background Facts.
    West Bank is a state-chartered Iowa bank.      Plaintiffs Darla and
    Jason Legg are former customers of West Bank.        They opened a joint
    checking account with West Bank on November 26, 2002. They closed
    their last account with West Bank in April 2013. The claims arising in
    this case, discussed in detail below, arise out of the payment of
    overdrafts and resulting NSF fees charged by West Bank.
    West Bank issues bank cards to its customers.       Customers use
    their bank cards in one of two ways: automatic teller machine
    withdrawals (ATM withdrawals) or point of sale purchases (POS
    purchases). Customers may also make electronic payments using their
    West Bank accounts that are processed in the same way as ATM
    withdrawals and POS purchases.       All three of these transactions are
    classified as “bank card transactions.”   When customers are issued a
    bank card, they receive a “Deposit Account Agreement” (Agreement). The
    Agreement provides that West Bank “shall have an obligation to
    4
    Depositor to exercise good faith and ordinary care in connection with
    each account.”
    When a customer of West Bank uses his or her bank card to begin
    a transaction, an electronic request is sent to Shazam. Shazam in turn
    sends an electronic request to Fiserv. Fiserv is a banking platform that
    processes payment requests for West Bank.               Based on the customer
    balance available at the time the electronic request is made, Fiserv either
    denies or allows the transaction.        The district court summarized what
    happens next as follows:
    When a customer uses a Bank Card, once the transaction is
    approved at the point of sale the bank is required to pay the
    transaction when presented, even if there are not sufficient
    funds in the account by the time the transaction is posted to
    the account. Such posting typically occurs one to three days
    after the original transaction.
    If West Bank is called upon to pay a Bank Card
    transaction when there are insufficient funds in the account,
    the bank advances sufficient money to cover the amount by
    which the account is short, and assesses a non-sufficient
    funds (NSF) fee. Those advances are automatically deducted
    from the customer account and repaid to the bank the next
    time a deposit sufficient to cover the advances is made to the
    account. 1
    Debit   card    transactions     are   thus    classified   as   “force-pay”
    transactions. Once they are authorized by Fiserv, West Bank is required
    to pay them, even if the customer’s account has insufficient funds at the
    time the transaction is processed. These transactions may be presented
    for payment up to three days after the transaction is approved.                 The
    decision to pay the bank card transaction is made separately from the
    1West  Bank disputes whether the services are automated. However, since facts
    are viewed in the light most favorable to the nonmoving party in a motion for summary
    judgment, we assume without deciding that the system in question is automated.

    695 N.W.2d 9
    , 14 (Iowa 2005).

    assessment of the NSF fee.       After the NSF fees are applied to a
    customer’s account, a reviewing West Bank employee has the discretion
    to waive the fees. The plaintiffs in this case had NSF fees waived on at
    least one occasion.   The NSF fee West Bank charged customers was
    originally $27.00. It was later raised to $30.00. West Bank sets its NSF
    fee based on market studies of competitors.
    West Bank does not post customer account balances in real time.
    Rather, transactions are posted in a batch at the end of the day. Prior to
    July 1, 2006, West Bank posted bank card transactions with the lowest
    amount for each day’s debits posted first and the highest amount posted
    last (low-to-high sequencing). After July 1, 2006, West Bank reversed its
    posting sequencing and posted bank card transactions with the highest
    amount posted first and the lowest amount posted last (high-to-low
    sequencing). Beginning October 1, 2010, West Bank changed its posting
    order back to low-to-high sequencing.
    After the 2006 change, a Miscellaneous Fees document was
    provided to customers that included two footnotes relating to sequencing.
    The first footnote stated, “[C]hecks written on your account will be paid
    in order daily with the largest check paid first and the smallest check
    paid last.” The second footnote provided that insufficient fund charges
    applied to “items” posted to accounts and defined items to include
    checks, money transfers, ATM debits, debit card debits, and ACH debit
    withdrawals.
    In 2009, footnote two on the Miscellaneous Fees document West
    Bank provided to customers was modified to state that overdrafts would
    be posted high to low, based on the amount of the transaction.          It
    provided that
    6
    [c]hecks written on your account will be paid in order
    daily with the largest items paid first and the smallest items
    paid last. NSF fees apply to overdrafts created by check, in
    person withdrawal, ATM withdrawal or other electronic
    means.
    West Bank discussed in an internal memo that the low-to-high
    sequencing had created a business expectation for customers.              West
    Bank acknowledged that an Iowa Bankers Association Compliance
    Officer had discussed the proposed high-to-low sequencing order with an
    attorney and concluded in an internal memo that customers would need
    to be notified of the change. The summary judgment record supported
    an inference that West Bank made the change without adequately
    notifying its customers.
    In August 2009, September 2009, and May 2010, the Leggs were
    charged NSF fees after West Bank instituted the new high-to-low
    sequencing. On August 31, the Leggs made two separate POS purchases
    in the amounts of $6.50 and $5.91, which resulted in overdrafts to their
    account. West Bank charged the Leggs $27.00 per POS purchase. On
    September 2, the Leggs made a $5.50 electronic payment which resulted
    in an overdraft to their account, and West Bank charged the Leggs an
    NSF fee of $27.00. The Leggs repaid these amounts on September 4. On
    September 17, the Leggs wrote a check for $560, which overdrew their
    account.    The Leggs also made two POS purchases in the amounts of
    $10.89 and $9.00. West Bank charged the Leggs an NSF fee of $27.00
    for each POS purchase, and the Leggs repaid both on September 18. 2 In
    all of these transactions, West Bank paid for the purchases.
    2Ifthese amounts were finance charges under the Iowa Consumer Credit Code,
    as the Leggs subsequently alleged, then the amount of each charge exceeded the
    twenty-one percent limitation contained in Iowa Code section 537.2201(2) (2009).
    7
    On September 17, if the bank card transactions had been posted
    in the low-to-high sequence, the Leggs would have only been charged one
    NSF fee for one overdraft. On May 17, the Leggs were charged four NSF
    fees for bank card transactions.              The Leggs would have only been
    charged two NSF fees if the transactions were posted low-to-high.
    II. Course of Proceedings.
    The Leggs filed this action as a proposed consumer class action on
    September 29, 2010.         Their petition has been amended twice.               The
    petition as amended includes six counts. Counts I, II, III, and IV arise
    under the Iowa Consumer Credit Code (ICCC).                 These claims are the
    “usury claims” and are based on the Leggs’ allegation that West Bank’s
    collection of NSF fees amounts to a finance charge in excess of twenty-
    one percent in violation of Iowa Code section 537.2201 (2009). Counts V
    and VI are the “sequencing claims,” and they arise from West Bank’s
    decision to process bank card transactions from high to low.
    On April 8, 2013, West Bank filed its first motion for summary
    judgment. The motion for summary judgment asked the district court to
    dismiss all of the Leggs’ usury claims except Count III, a claim arising
    under the Iowa Ongoing Criminal Conduct Act. See Iowa Code ch. 706A.
    The Leggs resisted West Bank’s first motion for summary judgment. On
    August 14, West Bank filed a second motion for summary judgment,
    seeking to dismiss the Leggs’ sequencing claims. The Leggs resisted the
    second motion for summary judgment. On September 5, West Bank filed
    a third motion for summary judgment, seeking to dismiss Count III. The
    Leggs resisted the third motion for summary judgment. 3
    3Theplaintiffs alleged West Bank violated chapter 706A because the willful and
    knowing charging of finance charges over the statutory limit was a qualifying criminal
    8
    Before the hearing on the motions for summary judgment, the Iowa
    Superintendent of Banking filed a “Superintendent Guidance” regarding
    the definition of finance charges under the ICCC. The guidance defines
    one-time NSF fees as “account fee[s] related to the maintenance of the
    customer’s deposit account with the bank.”                Iowa Superintendent of
    Banking, Superintendent Guidance No. SG-2014-01, One-Time Overdraft
    Fees (Jan. 7, 2014), available at www.idob.state.ia.us/bank/docs/
    bulletinguidances.aspx.       The Leggs assert this is a departure from the
    previous guidances and bulletins issued by the Superintendent.
    The district court held a hearing on West Bank’s three motions for
    summary judgment on January 9 and 10, 2014.                      In a ruling issued
    March 14, the district court denied West Bank’s motions for summary
    judgment on the usury and sequencing claims, and granted its third
    motion for summary judgment. After the district court ruling, the Iowa
    legislature amended the ICCC to exclude NSF fees from the definition of a
    finance charge. 4      West Bank applied for interlocutory appeal on the
    district court ruling on its motions for summary judgment, which we
    granted. West Bank also moved for interlocutory appeal on the district
    court ruling on class certification, which we also granted. We address
    _______________________________
    act. West Bank filed a motion for summary judgment on this claim, which the district
    court granted. No appeal was taken from that ruling.
    4The   amendment made an NSF fee an additional item expressly excluded from
    the definition of finance charge. The amendment reads as follows:
    (5) An initial charge imposed by a financial institution for returning an
    item presented against non-sufficient funds or for paying an item that
    overdraws an account. For the purposes of this subparagraph, “item”
    includes any form of authorization or order for withdrawal of funds from
    an account such as a check, automated teller machine card, debit card,
    automated clearinghouse or other means.

    (Iowa 2016).
    III. Standard of Review.
    Our review of a grant or denial of summary judgment is for
    corrections of errors at law. Griffen Pipe Prods. Co. v. Bd. of Review, 
    789 N.W.2d 769
    , 772 (Iowa 2010). “Summary judgment is appropriate when
    there is no genuine issue of material fact and the moving party is entitled
    to judgment as a matter of law.” 
    Id. We view
    the record in the light most
    favorable to the Leggs as the parties opposing summary judgment. 
    Id. IV. Analysis.
    We are asked to determine whether the district court ruling on
    West Bank’s motions for summary judgment was proper.          We address
    the remaining usury claims first, followed by the sequencing claims.
    A. The Usury Claims. The usury claims arise under the ICCC.
    The purpose of the ICCC is to “[s]implify, clarify and modernize the law
    governing retail installment sales and other consumer credit” and to
    “[p]rotect   consumers    against    unfair   practices.”     Iowa     Code
    § 537.1102(2)(a), (d) (2009).   The ICCC notes that it “shall be liberally
    construed and applied to promote its underlying purposes and policies.”
    
    Id. § 537.1102(1).
    The Leggs’ usury claims were challenged below on two grounds:
    (1) that the bank’s payment of the overdraft amounts did not constitute
    an extension of credit and (2) that the NSF fees were not finance charges.
    Because we find that the payment of the overdraft amount is not an
    extension of credit, we do not need to address whether the NSF fees were
    finance charges. This is because the cap on finance charges in the ICCC
    applies only to “creditors . . . extending credit in consumer credit
    10
    transactions.” 
    Id. § 537.1108(1).
    Similarly, the ICCC defines a finance
    charge as a charge that is “imposed . . . by the creditor as an incident to
    or as a condition of the extension of credit.”           
    Id. § 537.1301(21)(a).
    Therefore, since we find there is no extension of credit, we need not
    address whether the NSF fees constitute a finance charge.
    The Leggs argue that the payment of overdrafts constitute
    extensions of credit by West Bank. The district court concluded that the
    payments of overdraft amounts were extensions of credit under the
    ICCC. The ICCC “prescribes maximum charges for certain creditors . . .
    extending credit in consumer credit transactions.” 
    Id. § 537.1108(1).
    We
    must therefore decide whether the payment of overdrafted amounts on
    bank card transactions are an extension of credit under the ICCC.
    The ICCC defines “creditor” as a “person who grants credit in a
    consumer credit transaction.”     
    Id. § 537.1301(18).
          The ICCC defines
    “credit” as “the right granted by a person extending credit to a person to
    defer payment of debt, to incur debt and defer its payment, or to
    purchase property or services and defer payment therefor.”                  
    Id. § 537.1301(16)
    (emphasis added). In a number of consumer credit sale
    cases under the ICCC, this court has been asked to determine whether
    particular transactions constitute an extension of credit.           See, e.g.,
    Anderson v. Nextel Partners, Inc., 
    745 N.W.2d 464
    , 465 (Iowa 2008); State
    ex rel. Miller v. Nat’l Farmers Org., 
    278 N.W.2d 905
    , 906–07 (Iowa 1979).
    While this case does not deal with a consumer credit sale, the definition
    of credit under the ICCC is the same regardless of the type of consumer
    transaction—consumer credit sale, consumer lease, or consumer loan—
    and   thus,   we   find   these   cases   instructive.       See   Iowa   Code
    § 537.1301(12). In determining whether there was an extension of credit,
    we asked whether the individual had the ability to defer payments and
    11
    when the money was “due and payable.” See, e.g., 
    Miller, 278 N.W.2d at 907
    (“Nothing in the agreement allows the member to defer payment of
    dues. They are ‘due and payable’ at the date of making application and
    annually thereafter. Nor is any provision made for deferring payment of
    the annual assessment.”).
    In each of these cases, we held that the parties’ agreement needed
    to grant the debtor the right to defer repayment in order for there to be
    an extension of credit.     In Miller, we looked at the content of the
    membership agreement and ultimately concluded that the agreement did
    not constitute a grant of credit as it is defined under the ICCC. 
    Id. at 906–07.
      We were concerned with whether the membership agreement
    granted a right to the members to defer the payment of dues and
    assessments. 
    Id. at 907.
    The language of the membership agreement
    made dues due and payable at the time of signing and did not include
    any provision granting members the right to defer payment.         
    Id. We noted
    that “[d]elay by the [National Farmers Organization] in attempting
    to collect past dues and assessments does not establish that credit was
    granted; it only demonstrates forbearance in collecting sums which, if
    owed, were due and payable at the time the debts were incurred.” 
    Id. We held
    that there was no grant of credit and therefore the ICCC did not
    apply to the transactions in question. 
    Id. at 905.
    Similarly, in Muchmore Equipment, we examined the contract
    between the parties to determine if it contained a right to defer payment.
    Muchmore Equip., Inc. v. Grover, 
    315 N.W.2d 92
    , 98–99 (Iowa 1982),
    superseded by statute on other grounds, Iowa Code § 535.2(2)(a)(5)
    (1989), as recognized in Power Equip., Inc. v. Tschiggfrie, 
    460 N.W.2d 861
    ,
    863 (Iowa 1990). Because the contract required payment in full upon
    completion, we held that there was no extension of credit. 
    Id. at 98.
    In
    12
    Anderson, we again examined the service agreement between the parties
    to determine whether there was a right to defer 
    payment. 745 N.W.2d at 468
    –69.   The customers were required to pay charges “as they were
    billed.” 
    Id. at 468.
    We found that the agreement did not allow customers
    to defer payment of monthly invoices and that there was no extension of
    credit. 
    Id. at 468–69.
    Similar to the situation in these three cases, the Agreement signed
    by West Bank’s customers does not extend any right to defer payment.
    Rather, the Agreement expressly gives West Bank the right to
    immediately collect payment as soon as a customer deposits sufficient
    funds to cover the overdraft into their account.     In other words, the
    overdraft payment advanced on bank card transactions is due and
    payable at the time the account is overdrawn. The customer has no right
    to defer the payment past the first time there is sufficient money in the
    account to cover the repayment of the overdraft.      West Bank has the
    right to immediately withdraw the amount the bank paid for the
    overdraft from the customer’s account as soon as that amount is
    available. West Bank is not required to notify customers that the money
    sufficient to repay the overdraft will be withdrawn from their account
    because, at the time of the insufficient funds transaction, the amount the
    bank paid for the overdraft becomes due and payable.
    The plaintiffs argue that they have the right to defer payment of the
    overdraft amount because, by definition, it cannot be paid until a later
    date. However, the language of the ICCC is that an extension of credit
    exists when the “right . . . to defer payment” has been granted.      Iowa
    Code § 537.1301(16) (2009) (emphasis added).           Here, West Bank
    customers have not been granted a right to defer payment; rather, they
    must pay the bank back immediately upon their next deposit. This is
    13
    because the overdraft is due and payable as soon as it is created;
    customers have no right or choice to defer the payment past the next
    deposit sufficient to cover the amount owed.
    The Leggs also point to a line of cases where the court has held
    that payment of an overdraft on checks is either an unsecured loan or an
    extension of credit. See, e.g., Clinton Nat’l Bank v. Saucier, 
    580 N.W.2d 717
    , 720 (Iowa 1998).     However, these cases did not arise under the
    ICCC. See, e.g., 
    id. The ICCC
    definition of credit in section 537.1301(16)
    is much more narrow than the common law definition.            Iowa Code
    § 537.1301(16) (“ ‘Credit’ means the right granted by a person extending
    credit to a person to defer payment of debt, to incur debt and defer its
    payment, or to purchase property or services and defer payment
    therefor.”). When the legislature chooses to define words in a statute,
    “the common law and dictionary definitions which may not coincide with
    the legislative definition must yield to the language of the legislature.”
    Sherwin-Williams Co. v. Iowa Dep’t of Revenue, 
    789 N.W.2d 417
    , 425
    (Iowa 2010) (quoting Hornby v. State, 
    559 N.W.2d 23
    , 25 (Iowa 1997)).
    Therefore, we confine our inquiry to the definition of credit under the
    ICCC.
    Since we find that the payment of overdraft amounts on bank card
    transactions does not constitute an extension of credit under the ICCC,
    the district court should have granted West Bank’s motion for summary
    judgment on the usury claims.
    B. Sequencing Claims. The Leggs’ sequencing claims are based
    upon West Bank’s decision to switch from low-to-high sequencing to
    high-to-low sequencing between July 1, 2006, and September 30, 2010.
    The Leggs assert that the change to high-to-low sequencing resulted in
    14
    unjust enrichment to West Bank and was in violation of West Bank’s
    duty to act in good faith.
    1. Unjust enrichment. The Leggs assert that West Bank’s change
    to high-to-low sequencing with the intent to gain income for the bank
    resulted in unjust enrichment. 5 A claim for unjust enrichment “arises
    from the equitable principle that one shall not be permitted to unjustly
    enrich oneself by receiving property or benefits without making
    compensation therefor.”            Ahrendsen ex rel. Ahrendsen v. Iowa Dep’t of
    Human Servs., 
    613 N.W.2d 674
    , 679 (Iowa 2000). The Leggs allege that
    West Bank’s previous practice of posting bank card transactions from
    low-to-high created an expectation for its customers that it would
    continue to post in that order. They assert that any income the bank
    gained from the change in posting order was at the expense of customers
    and therefore unjustly enriched West Bank. West Bank counters that
    the Leggs cannot continue with their unjust enrichment claim because
    an express contract already exists that allows West Bank to charge
    customers       an   NSF     fee    for   insufficient    bank     card    transactions.
    Additionally, there is express contract language that addresses the
    5Count   V of the Leggs’ amended petition claim for relief reads as follows:
    WHEREFORE, Plaintiffs, individually and on behalf of the proposed class
    respectfully request that the Court order West Bank to repay to Plaintiffs
    and the proposed class all overdraft fees paid in excess of the statutorily
    allowable rate and all overdraft fees charged as a result of West Bank’s
    practice of sequencing Bank Card Transactions from highest amount to
    lowest amount, together with interest as provided by law, punitive
    damages, and for such further relief as is equitable.
    The plaintiffs’ claim for unjust enrichment seems to be based both on the usury claims
    (“in excess of the statutorily allowable rate”), and the sequencing claims (“practice of
    sequencing”). Because we conclude it was error for the district court not to grant
    summary judgment to West Bank on the usury claims, we only address the claim for
    unjust enrichment based on the practice of sequencing.
    15
    sequencing of postings.       The district court held that the unjust
    enrichment claim was not based on the express contract between the
    Leggs and West Bank, and therefore the Leggs could proceed with the
    claim.
    Contracts may be either express contracts or implied contracts.
    Hunter v. Union State Bank, 
    505 N.W.2d 172
    , 177 (Iowa 1993).              A
    contract is express when the parties reach an agreement by words. 
    Id. A contract
    is implied if it is manifested by the conduct of the parties. 
    Id. A person
    who pleads an express contract ordinarily cannot also recover
    under an implied contract. Scott v. Grinnell Mut. Reins. Co., 
    653 N.W.2d 556
    , 561 (Iowa 2002).      “An express contract and an implied contract
    cannot coexist with respect to the same subject matter, and the former
    supersedes the latter.”    Chariton Feed & Grain v. Harder, 
    369 N.W.2d 777
    , 791 (Iowa 1985). “Although we have held there may be a contract
    implied in law on a point not covered by an express contract, there can
    be no such implied contract on a point fully covered by an express
    contract and in direct conflict therewith.”    Smith v. Stowell, 
    256 Iowa 165
    , 174, 
    125 N.W.2d 795
    , 800 (1964). The district court found that the
    sequencing order in which West Bank posts bank card transactions was
    not expressly covered in the contract between the Leggs and West Bank.
    We do not agree.
    When the Leggs opened their account with West Bank, they signed
    a signature card on which they agreed “to be bound by the rules and
    regulations of this bank governing deposit accounts.” They also agreed
    “to the terms, conditions, fees and earnings of the account as outlined in
    the Deposit Account Agreement brochure provided.”          The Agreement
    specifically   addressed   NSF   fees.     The   Agreement     included   a
    Miscellaneous Fees document that listed the amount of all fees charged
    16
    by the bank, including NSF fees.                    Between 2006 and 2008, the
    Miscellaneous Fees document listed the amount owed per insufficient
    funds transaction (three free, then $27.00 each).                   It also noted in a
    footnote that “checks written on your account will be paid in order daily
    with the largest check paid first and the smallest check paid last.” This
    footnote was followed by: “Insufficient check charges apply to items
    posted in your account.             An item is defined to include the following:
    Check money transfer, ATM debit, debit card debit, ACH debit
    withdrawal.” In 2009 and 2010, the Miscellaneous Fees document listed
    NSF fees as $27.00 and included a similar footnote that stated:
    Checks written on your account will be paid in order daily
    with the largest items paid first and the smallest items paid
    last. NSF fees apply to overdrafts created by check, in-
    person withdrawal, ATM withdrawal or other electronic
    means.
    Further, the Agreements issued each year the Leggs were customers
    stated that the depositor agreed that the terms may be amended or
    modified from time to time.
    The signature card, along with the Agreement and accompanying
    documents, demonstrate that West Bank and its customers have an
    express agreement that allows West Bank to charge NSF fees on bank
    card transactions and grants West Bank discretion in choosing the
    sequencing order. Further, the Leggs’ petition does not allege what the
    implied contract term might be. 6              Because the issue of sequencing is
    6The     amended petition, as it relates to the unjust enrichment sequencing claims,
    only alleges:
    103. West Bank’s previous pattern and practice of debiting amounts
    from low to high had created an expectation in its customers that West
    Bank would debit accounts in that order and thus created an expectation
    that West Bank would continue to debit amounts from low to high.
    17
    expressly covered within the contracts between the Leggs and West
    Bank, no claim for unjust enrichment is available.              The district court
    erred by not granting summary judgment to West Bank on this claim.
    2. Good faith. Finally, the Leggs claim that West Bank breached
    the implied and express duties of good faith when it changed the
    sequencing order of bank card transactions to high-to-low without
    informing customers. West Bank argues that Article 4 of the Uniform
    Commercial Code (UCC) applies.           A comment to the good-faith section
    found in the general provisions of the UCC—which apply to all articles
    including Article 4—provides that the section
    does not support an independent cause of action for failure
    to perform or enforce in good faith. Rather, [the] section
    means that a failure to perform or enforce, in good faith, a
    specific duty or obligation under the contract, constitutes a
    breach of that contract.
    U.C.C. § 1–203 cmt., 1 U.L.A. 273 (2012). The district court held that
    the Leggs may maintain a cause of action against West Bank on this
    claim based upon the express contractual good-faith obligation contained
    in the Agreement and upon an implied obligation on the part of West
    Bank to exercise discretion in good faith in carrying out the terms of the
    contract.
    When the Leggs opened their account with West Bank, they were
    provided with an Agreement that included the statement that West Bank
    _______________________________
    104. West Bank’s enrichment was at the expense of Plaintiffs and Class
    Members.
    105. It is unjust to allow West Bank to retain the above benefits under
    the circumstances and the overdraft fees should be returned to Plaintiffs
    and Class Members.
    106. West Bank acted with willful and wanton disregard to the rights of
    Plaintiffs and Class Members, entitling Plaintiffs to recover punitive
    damages.
    18
    “shall have an obligation to Depositor to exercise good faith and ordinary
    care in connection with each account.” Before West Bank initiated the
    sequencing change, it consulted with an Iowa Bankers Association
    Compliance Officer. After this consultation, West Bank concluded in an
    internal memo that the previous practice of posting low-to-high created a
    business expectation with customers and it would be necessary to notify
    them of the change. Although West Bank’s memo specifically discussed
    notifying its customers of the sequencing change with regard to bank
    card transactions, West Bank nonetheless made the change without
    notifying customers.
    The district court, relying on the opinions of other courts that have
    heard similar issues, concluded that the plaintiffs could pursue their
    good-faith claims.     One case the district court discussed addressed
    whether express contract terms were being carried out in good faith. In
    In re Checking Account Overdraft Litigation, the plaintiffs argued that the
    banks violated express contractual provisions to act in good faith by
    reordering postings to high-to-low sequencing. 
    694 F. Supp. 2d 1302
    ,
    1315 (S.D. Fla. 2010).     The court found that the plaintiffs were not
    asking to vary the terms of the express contract. 
    Id. Rather, they
    were
    asking that the bank carry out its express agreement to exercise its
    discretion regarding the posting sequencing in good faith. 
    Id. at 1315.
    The court cited to a number of cases where other courts held that “when
    one party is given discretion to act under a contract, said discretion must
    be exercised in good faith.”   Id.; see Amoco Prod. Co. v. Heimann, 
    904 F.2d 1405
    , 1411–12 (10th Cir. 1990); Alexander Mfg., Inc. v. Ill. Union Ins.
    Co., 
    666 F. Supp. 2d 1185
    , 1206 (D. Or. 2009); Bybee Farms LLC v.
    Snake River Sugar Co., No. CV–06–5007–FVS, 
    2008 WL 4454054
    , at *12
    (E.D. Wash. Sept. 29, 2008).
    19
    Similarly, West Bank has discretion with regard to the sequencing
    order of bank card transactions in its agreements with the Leggs and its
    other customers. The bank wrote the duty of good faith into its contract
    with customers. The Leggs could reasonably argue that the change in
    sequencing of bank card transactions, coupled with the lack of
    notification, violated the reasonable expectations of customers that the
    bank act in good faith when exercising its discretion to sequence
    transactions. Therefore, the district court did not err in denying West
    Bank’s motion for summary judgment on the express contractual
    provision requiring West Bank to act in good faith. Because we find an
    express contract governs West Bank’s duty to act in good faith, we find
    the district court erred in concluding that a claim based on an implied
    duty of good faith was preserved. See, e.g., Chariton Feed & 
    Grain, 369 N.W.2d at 791
    (“An express contract and an implied contract cannot
    coexist with respect to the same subject matter, and the former
    supersedes the latter.”).
    C. Limitation of Actions.       West Bank argues that the Leggs’
    usury claims are subject to a one-year statute of limitations under Iowa
    Code section 537.5201(1).     The bank argues that section 537.5201(1)
    limits the claim for damages to one year and section 537.5201(3) limits
    claims for excess charges to one year. 
    Id. § 537.5201(1),
    (3). Because we
    dismiss the plaintiffs’ usury claims, we decline to address what the
    appropriate statute of limitations would be under the ICCC.
    The only remaining claim—that the bank violated the express duty
    of good faith—is a contractual claim. Iowa Code section 614.1 covers the
    statute of limitations for both written and unwritten contractual
    provisions. 
    Id. § 614.1(4)–(5).
    Written contracts are subject to a ten-year
    statute of limitations, while unwritten contracts are subject to a five-year
    20
    statute of limitations. Id.; see also Robinson v. Allied Prop. & Cas. Ins.
    Co., 
    816 N.W.2d 398
    , 402 (Iowa 2012).
    In order to determine the appropriate statute of limitations for a
    cause of action, we look to the foundation of the action. Sandbulte v.
    Farm Bureau Mut. Ins. Co., 
    343 N.W.2d 457
    , 462 (Iowa 1984), overruled
    on other grounds by Langwith v. Am. Nat’l Gen. Ins. Co., 
    793 N.W.2d 215
    ,
    223 (Iowa 2010). “In order for a cause of action to be founded upon a
    contract in writing, the instrument itself must contain an undertaking to
    do the thing for the non-performance of which the action is brought.”
    Matherly v. Hanson, 
    359 N.W.2d 450
    , 455 (Iowa 1984) (quoting Kersten v.
    Cont’l Bank, 
    628 P.2d 592
    , 594–95 (Ariz. Ct. App. 1981)).
    In the past, when we have been faced with a claim based solely on
    the breach of the implied covenant of good faith, we found the claim was
    based on an unwritten contract and the five-year statute of limitations
    applied.   
    Sandbulte, 343 N.W.2d at 460
    .         However, we have also
    recognized that claims based on specific, written contracts fall under the
    ten-year statute of limitations contained in section 614.1. See, e.g., Bob
    McKiness Excavating & Grading Co. v. Morton Bldgs., Inc., 
    507 N.W.2d 405
    , 408 (Iowa 1993). In this case, the Leggs’ claim for the breach of the
    duty of good faith comes from the Agreement itself. The document itself
    states that West Bank will act in good faith with regard to sequencing.
    Because we find that the plaintiffs may only proceed on a claim of a
    breach of the duty of good faith based on the written contractual
    provision between customers and West Bank, we likewise find that the
    appropriate statute of limitations that governs this action is the ten-year
    limitation for written contractual provisions.
    21
    V. Conclusion.
    We conclude that the district court erred when it denied summary
    judgment to West Bank on all the claims except the claim based on a
    potential breach of the express duty of good faith in the sequencing of
    postings of bank card transactions.     The case is remanded for further
    proceedings consistent with this opinion.
