    OPINION
    _________
    BRUGGINK, Judge.
    This case presents a dispute between Woodies Holdings, L.L.C.
    (“Woodies” or “plaintiff”) and the United States, acting through the General
    Service Administration (“GSA”). The issue is whether GSA met its
    contractual obligation to reimburse Woodies for a portion of real estate tax
    1
    Pursuant to the Protective Order issued in this case, this opinion was first
    issued under seal to afford the parties an opportunity to propose the
    redaction of protected information. Redacted material is indicated using
    brackets.
    adjustments Woodies paid to the District of Columbia for a building in
    which GSA was leasing office space. There is no dispute that GSA ceased
    remitting tax adjustment payments in 2012. Defendant has counterclaimed
    for the amount it believes that it overpaid Woodies before it stopped making
    tax adjustment payments. The government’s principle defense is that it
    made a mistake as to the total size of the building in which it was leasing
    space when it agreed to the percentage of future tax increases that it would
    pay. It asks the court to reform the contract to reflect the percentage that
    GSA would have agreed to had it not been operating under a misimpression
    as to the size of the building. Trial was held over six days in June and July
    2018 in Washington, DC. We find no basis to reform the contract because
    defendant has not met its burden in proving a unilateral mistake of fact.
    BACKGROUND
    This case concerns five leases between GSA and Woodies for office
    space in a commercial building in downtown Washington, DC known as the
    “Woodies Building.” The Woodies Building is a ten-floor mixed use
    building in which the basement and first two floors are outfitted for retail
    use, and the remaining floors are set aside for office space. The building
    has approximately 500,000 square feet of usable interior space and occupies
    an entire city block. The first lease, Lease 1641, was entered into by GSA
    for use by the Environmental Protection Agency (“EPA”) and, although
    critical to this case, is not directly at issue in these two lawsuits. 2 The four
    other leases, which are the subject of the two complaints, are referred to as
    Leases 1751, 1809, 1838, and 2154. They were for use by the Federal
    Bureau of Investigation (“FBI”); each covered one floor of the building and
    ran for a period of 10 years.
    The leases contain identical provisions for the sharing of property tax
    increases or decreases assessed by the District of Columbia (“DC”) as the
    leases go forward in time. Assuming an increase in local property taxes
    over the base year, these tax adjustment clauses require GSA to pay a
    percentage of that increase to Woodies. 3 The general aim of the provision
    2 It is not at issue because GSA made all of the tax adjustment payments as
    requested by Woodies.
    3 We previously held in a related action that GSA and Woodies agreed upon
    a value to be used for the base year figure in the real estate tax adjustment
    2
    is that the percentage of increase to be borne by the government as lessee
    should be proportionate to its percentage of occupancy of the building.
    The parties differ, however, as to how to view this term in
    application—plaintiff views the formula used in the leases less as a product
    of mathematical precision and more the product of subjective negotiations,
    while defendant views it as the result of a purely mathematical exercise
    (creating an accurate fraction). As we discuss later, representatives of
    both parties testified to their respective understanding of how the formula
    was developed, pointing to different language in the contracts to support
    their views. 4
    Defendant cites the Tax Adjustment clause itself, which requires a
    straightforward application of a fraction to determine the percentage to be
    paid: The numerator represents the space leased by the government, and the
    denominator represents the total rentable space of the building. Leases
    1751, 1809, and 2154 contain the identical provision: Section 3.2(F) of SFO
    No. 04-005, a government-drafted form, which was the solicitation that
    resulted in these three leases and was incorporated into the final contract.
    Before the figures were filled in, it read:
    The Government shall pay its share of tax increases or shall
    receive its share of any tax decrease based on the ratio of the
    rentable square feet occupied by the Government to the total
    rentable square feet in the building . . . (percentage of
    occupancy).       For the purposes of this lease, the
    Government’s percentage of occupancy as of the date hereof
    is ________ percent based on upon an occupancy of
    calculation. Woodies Holdings, L.L.C. v. United States, 
    115 Fed. Cl. 204
    (2014). That holding was applied to this case on summary judgment.

    4
    We have already held against defendant on its contract interpretation
    argument because there is no ambiguity or nonsensical result in the literal
    application of the as-written language; nevertheless, it is helpful to review
    the clauses and positions of the parties in this regard to understand the
    context in which the parties’ arguments are made as it concerns defendant’s
    defense of mistake. See Woodies Holding L.L.C. v. United States, No.

    ________ rentable square feet in a building of ________
    rentable square feet.
    DX 44 at 48; DX 49 at 46; DX 51 at 48. 5 In the government’s view, the
    intention of the parties in this clause is plain: GSA would pay precisely the
    amount of increase equal to its percentage of occupancy of the building.
    Any deviation from the size of the leased space or the total size of the
    building must have been the product of some misrepresentation or mistake;
    the theory claimed at trial is one of unilateral mistake.
    Plaintiff, on the other hand, calls attention to the very next section of
    the solicitation, Section 3.3, Percentage of Occupancy, which states that
    “[t]he percent of the building occupied by the Government, for purposes of
    tax adjustments, will be established during negotiations,” which is precisely
    what plaintiff alleges was done. 
    Id. In plaintiff’s
    view, as its principals
    and agent testified, the percentage of occupancy was the subject and result
    of discussion between the parties about whether retail space was to be
    included in the total building size.
    The figures inserted for the first three leases are 12.98% percentage
    of occupancy based on a “total building square footage . . . determined to be
    372,990 BOMA rentable square feet.” E.g., DX 44 at 2. The space
    leased in all three of those leases was “48,410 BOMA rentable square feet.”
    E.g., 
    id. Lease 2154,
    a substantially smaller lease, had a percentage of
    occupancy of 2.8% based on only 10,453 rentable square feet. DX 70 at
    1-2. Lease 1838 was later amended to upwardly adjust the percentage
    because the seventh floor was expanded, which added 6,680 square feet of
    rentable space, resulting in a new occupancy percentage of 14.77%. DX
    132 at 1.
    The Woodies Building in actuality, if one includes both retail and
    office space, contains approximately 500,000 square feet of rentable space.
    Had that larger number been used in the tax adjustment clause, the
    government’s percentage of occupancy would have been smaller, along
    with its share of tax increases. Defendant thus urges that the numbers
    5
    The final lease, Lease 2154, contains an identical provision, but it is found
    in SFO No. 07-014, a later solicitation, also incorporated into the lease
    contract. DX 70 at 26.
    4
    used were a mistake and, because Woodies, as the owner, knew the real size
    of the building, reformation of the contract is appropriate.
    Plaintiff avers the opposite: GSA selected the number initially used
    for total building size, and Woodies had no reason to think it was a mistake
    because its agent discussed the figure with GSA before the contract was
    signed. We turn now to the particulars of how these leases were entered
    into as the evidence was presented at trial.
    I.   GSA’s AAP Process
    In the early 1990s, GSA implemented a program to streamline its
    acquisition of leased space for government agencies during a time when
    demand was high from federal agencies, especially defense related
    agencies. GSA Contracting Officer (“CO”) Jim Smale recounted that he
    was heavily involved in the efforts to come up with a more efficient and
    timely way to meet agency demand in the 1990s, which resulted in the
    creation of the Advanced Acquisition Program, referred to throughout the
    trial as the “AAP.” Mr. Smale explained that the aim of the AAP was to
    have a stable of properties ready to be leased to the government without the
    need for separate solicitations and offers every time an agency need arose.
    The AAP “created an inventory of best and final offers that we could then
    draw down against space requests that would come into the agency.” Tr.
    26. The AAP resulted in an “annual inventory . . . where everything had
    been set and determined except for the size of the requirement and the
    location.” Tr. 27. Once GSA received a request for space from a federal
    agency, it could compare the desired location and space required with its
    inventory in the AAP and find the best match for the best price. This
    process “could take place in a matter of days.” 
    Id. Mr. Smale
    was the
    original CO for the AAP once it was in place.
    GSA would issue yearly solicitations for each general region, here
    the National Capital Region, in order to keep its inventory fresh and make
    sure that the status quo had not changed. Offerors could leave their offers
    open from year to year or they could refresh them to update prices or space
    offered; they were permitted to withdraw offers at any time throughout the
    year. Mr. Smale testified that the AAP was a great success.
    Because the process was meant to complete up front as much as
    possible of the preliminary work necessary to identify whether a space met
    5
    agency needs, offerors were required to submit a significant amount of
    supporting documentation with their initial AAP offers. This included,
    among other things: a Form 1364; a Form 1217 (Lessor’s Annual Cost
    Statement,” which included square footage information); as-built floor
    plans for each floor with “space not offered to government crosshatched
    and noted;” a BOMA Global Summary of Areas for the entire building
    “certified by a registered architect;” CAD files supporting the drawings; and
    any additional information necessary “in order for the government to
    perform a complete and adequate analysis of the offered property.” E.g.,
    PX 16 at 6-7 (SFO No. 02-001).
    As offers came in, GSA reviewed them to determine if they met the
    solicitation requirements for that region. Often the CO and/or other
    agency personnel would meet with qualified offerors to hold discussions
    regarding their offers. Woodies’ agent and attorney, Mr. Edward
    Gregorowicz, testified that he participated in many such meetings regarding
    the Woodies Building after he submitted offers on Woodies’ behalf.
    These meetings would have been for the purpose of ironing out any missing
    details, reaching agreement on the numbers regarding square footage,
    answering GSA questions, and for encouraging offerors to lower their
    prices. After these discussions, offerors submitted their best and final
    offers with the final price term no longer subject to revision. Mr.
    Gregorowicz also testified that GSA’s architects would confirm the square
    footage figures during this period and often discussed with Woodies’ own
    architect the numbers to be used. 6
    Once an offeror was selected to meet an agency need, drafts would
    be circulated between the parties to iron out final details, such as riders
    concerning construction or improvements to be completed before handover
    of the property and the percentage of occupancy. Mr. Smale testified that
    he relied on his lower level personnel at GSA to review all of the
    information provided by offerors and to verify its accuracy.
    II.   Lease 1641
    Although lease 1641 is not directly at issue in this suit, other than a
    two-year extension later negotiated by the parties, it is of critical importance
    6
    Multiple GSA witnesses explained that this was only for the purpose of
    measuring the leased space, not the entire building.
    6
    because this is where what defendant characterizes as a mistake was first
    made. This mistake was then repeated for the leases at issue.
    A. Woodies’ Unsuccessful Offers
    There were several unsuccessful offers made by Woodies in the
    years prior to Lease 1641’s execution, and those offers provided accurate
    information regarding the building size to GSA. In late 2000, GSA issued
    AAP solicitation No. 00-011 for office space in downtown Washington,
    DC. Woodies, through its agent, Mr. Gregorowicz, submitted an offer to
    lease space in the Woodies Building. Included in that offer was a
    completed GSA Form 1364. 7 On that form, plaintiff detailed the building
    space as follows: Office Space of 316,420 BOMA rentable square feet
    (“BRSF”); Retail Space of 163,609 BRSF; and total building square feet of
    480,029 BRSF. 8 DX 4 at 13. No lease resulted from this offer.
    On October 12, 2001, GSA issued its yearly solicitation to refresh
    offers, SFO No. 02-001. Mr. Gregorowicz again submitted an offer on
    7
    Form 1364 is a standard GSA form in which offerors list general building
    information. The look of the form and some of the information solicited by
    it changed throughout the years.
    8
    Throughout the documents presented at trial, the standard of measurement
    for space varied greatly. The only constant was the term “BOMA,” which
    refers to the Building Owners and Manager Association, an industry group
    that seeks to standardize measurements in the real estate industry. We saw
    terms such as “BRSF,” “BOMA Office Usable SF,” “BOMA Office Area
    square feet of office and retail space,” and “BOMA office Area sq. ft.” We
    have come to understand that even BOMA regularly changes the precise
    definitions of the terms. Further complicating matters, GSA promiscuously
    used the different terms to reference the same matter from document to
    document. This led to some frustration during trial due to the imprecision
    that this necessarily created. The testimony of Mr. Turowski, a former
    GSA Policy Director, was exhibit A. He testified regarding a BOMA
    measurement that he recalled excluded retail space, but then the document
    from which he was testifying appeared to suggest otherwise, but we are
    unable to resolve that particular dispute because the entire document was
    not introduced.
    7
    behalf of plaintiff for space in the Woodies Building. The Form 1364 for
    this offer contains similar figures as the prior year: 346,081 square feet of
    “general purpose” space and 146,778 square feet of “retail space.” DX 5
    at 6 (initial offer); see also DX 6 at 8 (best and final offer for that year).
    This offer also did not result in a lease with Woodies.
    B. Success: Solicitation 02-019
    In November 2002, GSA issued AAP solicitation No. 02-019.
    Woodies submitted its best and final offer on December 13, 2002. The
    Form 1364 for that offer listed the available space as 372,990 BRSF for
    office space, 139,240 BRSF for retail space, and 512,230 BRSF “Total
    building square feet.” 9 PX 20 at WHL0005135. The parties do not
    dispute that this was accurate information. This time, the Woodies
    Building was selected for award of a contract to lease one floor of space for
    use by the EPA.
    A contractor for GSA, Todd Valentine, was charged with finalizing
    the contract details with Woodies.     Although he did not possess authority
    to obligate the government, Mr. Valentine acted as the designee for the
    contracting officers involved in these leases. He prepared the documents
    executed by the contracting officers. It is apparent from their testimony
    that they relied on him to negotiate the particulars of leases and would have
    signed whatever he put in front of them. In April 2003, Mr. Valentine sent
    several drafts of the lease to Woodies. See DX 14 (April 18, 2003 cover
    email); DX 15 (April 30, 2003 cover email). The cover emails attached to
    those drafts indicate that the lease needed some fine-tuning regarding
    construction that was yet to be completed by Woodies in the space. There
    is no evidence that Woodies submitted any incorrect or incomplete
    information in these drafts regarding the building size.
    Mr. Valentine testified that, at some point prior to the final signed
    lease, he inputted the 12.98% for the percentage of occupancy and the
    372,990 total building square footage upon which the percentage was
    9
    The relatively minor variance in these numbers across the Form 1364s
    was not of concern to the parties, nor is it of concern to the court. Multiple
    witnesses explained that the variations resulted from changing
    measurements, changing definitions of how to measure space, and even
    changes to the space itself (additions and improvements).
    8
    calculated. Tr. 243-44; see DX 20 at 2 (draft lease with changes
    tracked). 10 He could not recount where those figures came from but did
    hazard a guess that he must have inadvertently selected 372,990 from one of
    Woodies’ previously submitted Form 1364s (all of which contained
    accurate figures at that point in time). 11 With 372,990 selected for the
    total building size, it was a simple math exercise to use the 48,410 BRSF as
    the numerator and come up with the fraction that equaled 12.98%.
    Mr. Gregorowicz confirmed that the use of 12.98% in lease 1641
    was not a separately negotiated figure. In his eyes, however, no mistake
    was made because the exclusion of retail space from the total building size
    had been cleared ahead of time, both with Mr. Jemal on Woodies’ end and
    with Mr. Smale (or other appropriate GSA employees) on the government’s
    end. We will discuss in more detail below the testimony of Mssrs.
    Valentine and Gregorowicz as it pertains to the theory of mistake.
    After final reviews by both parties, lease 1641 was executed on June
    24, 2003, by CO Don Brown at GSA. 12 The percentage of occupancy
    stated was 12.98% based on a total building size of 372,990 square feet.
    None of the Form 1364s submitted by Woodies prior to execution were
    incorporated into the lease. The Form 1217 that was incorporated into the
    lease listed 346,081 as the usable square footage for the building. 13 All of
    10
    The document admitted into evidence, DX 20, which shows tracked
    changes in an undated draft lease, does not make clear when the allegedly
    erroneous numbers were inserted. Mr. Valentine was not questioned about
    the document. Mr. Gregorowicz was, but he was not asked when he first
    saw those numbers from GSA; he did confirm that it was GSA that inserted
    the 12.98% and 372,990 figures into the lease.
    11
    Plaintiff makes much of the point that Mr. Valentine never independently
    concluded that he had made a mistake until he was contacted by GSA
    counsel 13 years after the fact (lease 1641), who informed him that the
    leases used an incorrect total building size. We do not view this fact as
    establishing a lack of mistake, but instead it suggests a relative lack of
    attention to the details of the transactions on which Mr. Valentine worked.
    12
    Mr. Brown did not appear at trial, but we have his signature on the lease.
    13
    “Usable” and “rentable” square footage are the result of different
    9
    the contracting officers who testified were consistent that they wholly relied
    on Mr. Valentine and others to review the offeror’s supporting information.
    E.g., Tr. 398-400 (Testimony of CO Larry Sutton that he totally relied on
    Mr. Valentine). And, although Mr. Valentine agreed that it was his job to
    ensure the accuracy of any figures and to review all lease-related
    submissions prior to execution, he did not, in fact, review any of the
    numerous supporting documents originating from Woodies, such as the
    CAD drawings or the BOMA building summary. Tr. 272-73, 278. “I
    just – I didn’t review it. We would typically rely on the square footage
    that’s in the 1364 or 1217.” Tr. 273 (answering question regarding
    whether he reviewed the BOMA global summary of the Woodies Building).
    Mr. Valentine also testified that he could not recall ever having submitted
    supporting documentation to Mr. Brown or any other CO to review prior to
    signing the leases. See Tr. 295-97.
    II.   Leases 1751, 1809 and 1838
    After having successfully placed the EPA in the Woodies Building
    with lease 1641, both parties were interested in GSA leasing additional
    space in the Woodies Building. GSA issued SFO No. 04-005 in early
    December 2003. Plaintiff submitted an initial offer later that month, again
    through Mr. Gregorowicz. The Form 1364 attached to this offer used
    356,081 and 314,462 for total usable and rentable square footage figures. 14
    PX 22 at EVG001041. The form also listed the building as comprised of
    “eleven” floors. 
    Id. This iteration
    of Form 1364 did not have a box for
    retail space; instead there were boxes for “warehouse” and “other” space.
    Mr. Gregorowicz left those boxes blank. 
    Id. The Form
    1217 attached
    reflected that the entire building contained 346,081 square footage. 
    Id. at EVG001044.
    Woodies submitted its best and final offer on February 26,
    calculations at GSA. Usable square footage excluded certain areas that
    were included in the rentable numbers. The precise definition is
    unimportant for our purposes.
    14
    We note that the 314,462 number is the same as that listed by Woodies as
    the total available usable square footage to be leased in the building on its
    cover page for its best and final offer. See PX 23 at WHL0005223. We
    infer that this number was smaller for the offers subsequent to lease 1641
    because that floor was no longer usable space offered to the government for
    future leases.
    10
    2004. It did not include an updated Form 1364 or 1217 for the Woodies
    Building, nor did Woodies reserve any exceptions to the solicitation.
    SFO No. 04-005 resulted in three lease awards to Woodies, 1751,
    1809, and 1838, each representing a single floor of the building for use by
    the FBI. Mr. Valentine testified that he likely reused the tax adjustment
    figures from Lease 1641, although he could not be sure when looking at the
    redlined version of Lease 1751 or any of the others. He could not have cut
    and pasted from any of the offer submissions from SFO No. 04-005 because
    this time Woodies did not use 372,990 as the total building size in either the
    1364 or 1217 forms. Tr. 285-86. He was sure, however, that he did not
    purposefully exclude the retail space from the total building size for any of
    those leases tax adjustment clauses. Tr. 281, 287, 295. He could not
    recall ever having done such a thing nor why he might ever have done it.
    Lease 1751 was executed by CO Larry Sutton on August 3, 2004;
    Lease 1809 was signed on December 13, 2004; and Mr. Sutton executed
    Lease 1838 on March 7, 2005. All three leases contain Mr. Valentine’s
    figures of 372,990 for total building size and a percentage of occupancy of
    12.98% in the tax adjustment clause. DX 44 at 2; DX 49 at 2; DX 51 at 2.
    Mr. Sutton was asked what he believed the 372,990 number in those clauses
    represented at the time that he signed the leases. As to all three, he
    believed that the number was the accurate total for all of the rentable square
    footage in the building. Tr. 384-86. He was also asked whether, at the
    time he signed the leases, he was aware that there was retail space in the
    Woodies Building. His answer was “no.” Tr. 389. His belief in the
    accuracy of these figures was based simply on the fact that they were in the
    lease. See Tr. 384 (“Umm, based upon what I saw in the lease SF-2 of the
    documents, whatever that number was, I thought that was the total building
    square footage.”). As mentioned earlier, it was not Mr. Valentine’s
    practice to submit any supporting information along with the lease
    documents to the CO, nor, in any event, was it Mr. Sutton’s practice to
    review any such information.
    On March 17, 2006, the parties executed a supplemental lease
    agreement (“SLA”) to Lease 1838 which expanded the leased premises by
    6,680 rentable square feet. DX 132 (SLA No. 1 to Lease 1838). The tax
    adjustment clause was upwardly adjusted to account for the additional space
    to a 14.77% figure based on the same 372,990 total building size. 
    Id. at 2.
    This SLA was executed by CO, and former AAP manager, Santoni Graham
    11
    at GSA. He, like Mr. Sutton before him, testified that he believed that
    372,990 represented the size of the entire building. 15 Tr. 465-66. He did
    not know who inputted those figures into the SLA that he signed, but he
    surmised on the stand that it must have been a realty specialist. He, again
    like Mr. Sutton, did not recall having reviewed any of the lease paperwork
    or submissions from Woodies prior to signing the SLA.
    IV.   Lease 2154
    On May 1, 2009, GSA issued SFO No. 07-014 under the new
    Automated Advanced Acquisition Program (“AAAP”), which was an
    update to the AAP which took the program into the digital age. Offerors
    now submitted their offers electronically, and GSA’s AAAP software
    calculated and ranked their prices automatically. Under the AAAP,
    offerors could submit new proposals or update existing offers on a rolling
    basis during the first and seventh day of every month. 16 Tr. 512
    (Williams).
    Plaintiff submitted its response to SFO No. 07-014 on July 9, 2009.
    DX 64. Mr. Gregorowicz testified regarding the process that he undertook
    to submit an offer through the AAAP. Rather than submitting electronic
    copies of documents, such as Forms 1364 or 1217, the AAAP process was
    15
    There was a later SLA for lease 1838 that reverted to the prior 12.98%
    figure for percentage of occupancy. See DX 132. CO Santoni Graham
    was unsure how or why that figure was used after the lease was specifically
    amended to add more space with SLA No. 1.
    16
    The government states in its briefing, citing Mr. Williams’ testimony
    regarding the rolling basis of AAAP offer submissions, that formal
    discussions were no longer held under the AAAP program. Although we
    are unable to infer the same from Mr. Williams’ testimony, it is not a point
    disputed by plaintiff. We also note, however, that Mr. Lynch, a GSA
    contractor who worked as an AAAP project manager during this time,
    testified that offerors would regularly call the project managers to discuss
    how to input their offers into the AAAP. Tr. 1298-99. Plaintiff points
    to this open nature of communications between GSA and offerors as
    representing no great departure from the prior period when formal
    discussions were held between initial and final offers under the AAP.
    12
    such that offerors were asked questions via an online portal and then the
    AAAP system populated the GSA forms with their answers. See Tr.
    760-64. Because the AAAP system afforded no opportunity to upload
    documents, plaintiff did not submit a BOMA chart or other documents that
    might have contained the full figures for the Woodies Building’s total size
    as they had done previously under the AAP. 17 Tr. 772 (Gregorowicz).
    Mr. Gregorowicz explained, however, that, given the parties’ prior
    use of 372,990 for the total building size, when answering a question
    regarding the building size, he “followed up with a phone call to the GSA
    person who [he] knew was handling this to explain why [he] did it.” Tr.
    773. He was sure that the person at GSA with whom he spoke concerning
    the issue of total building size was a male, and, although he was not
    completely sure who it was, he stated that it was most likely Kirkland
    Williams. 
    Id. He further
    recounted that, when the lease came back for
    Woodies’ signature, it “reflected 372,990 for tax purposes, which is what
    the previous four leases had, so in my mind, I asked the question and they
    answered it by sending out the lease that way.” 
    Id. (answering the
    court’s
    question whether he received a response to query whether the CO would
    accept 372,990 for the total building size).
    Kirkland Williams, the GSA AAAP program manager at the time,
    testified that he reviewed AAAP submissions and handled finalization of
    the lease with Woodies. Tr. 514, 522, 530. The resulting Lease 2154
    used 372,990 for the total building size, which resulted in a 2.8% figure
    used for the percentage of occupancy, reflecting the significantly smaller
    lease on the eighth floor (10,453 BRSF). Mr. Williams testified that he
    believed the 372,990 number was accurate because that is what was present
    in the Forms 1364 and 1217 generated by Woodies’ AAAP submission. 18
    17
    Mr. Gregorowicz also testified that he believed that he had submitted
    CAD drawings for the entire building on a disk along with BOMA figures
    for the building. Unlike submitting an offer under the AAP, he testified
    that he did not physically deliver these documents to GSA along with the
    offer, which was another reason prompting him to call GSA to discuss the
    issue. Tr. 774. Defendant points out that no supporting documentation
    was submitted at trial containing the accurate information for the entire
    building.
    18
    Another GSA employee, Mr. Gregory Otten, testified, however, that, as
    13
    He did not recall having spoken with Mr. Gregorowicz about the total
    building size, but when asked by the court whether he recalled speaking
    with Mr. Gregorowicz about the deal generally, Mr. Williams confirmed
    that he spoke with him multiple times about the Woodies Building during
    the lead up to lease 2154’s execution. Tr. 538. He also confirmed that he
    was aware, at the time, that the building had 11 floors and that the seventh
    floor contained approximately 48,000 square feet, as confirmed by GSA’s
    architect Wendy Coonin. But, Mr. Williams was not concerned with the
    building size at the time, nor did he ask Ms. Coonin to tally the floors and
    confirm the building size. Tr. 557.
    Lease 2154 was executed on May 19, 2010, by CO Michelle Parrish
    for GSA and Mr. Jemal for Woodies. Ms. Parrish was aware that the
    Woodies Building contained retail space. Tr. 573.
    V.   Two-Year Extension of Lease 1641
    Lease 1641, signed in 2003, had a 10-year term. As the expiration
    of that term approached, Woodies began inquiring of GSA whether it, and
    by extension the EPA, were interested in extending the lease. Brian
    Sullivan, a real estate broker representing Woodies, sent an email with an
    offer to extend the lease in June 2013 to Marcia Parkes, the GSA CO
    handing lease 1641 at the time. See DX 197. Woodies desired to enter a
    long-term extension; GSA desired a short-term extension. Tr. 858
    (Parkes). This prompted a series of offers from Woodies that narrowed
    the lease term and upped the rental rate to account for the shorter duration.
    See DX 199; DX 208; DX 215. Ms. Parkes testified that the size of the
    Woodies Building was not an issue during these negotiations. The
    percentage of occupancy figures were adopted from the original lease. No
    solicitation or supporting documents (GSA forms or BOMA charts) were
    exchanged. Tr. 866-67 (Parkes). Mr. Sullivan did state in an email
    during their correspondence regarding the price per square foot that
    Woodies was paying approximately $4 million in taxes “for the 372,990
    BRSF building.” DX 218 at 2. She recounted that Mr. Sullivan was
    using that information to justify an increase from $43.21 per rentable square
    foot to $48 per square foot in the extension. Tr. 861-62. She testified
    of 2014, Mr. Williams told him that he did not know where the total
    building size number had come from. Tr. 1023-24.
    14
    that she believed those figures represented the entire building and had no
    reason to think that they excluded retail space.
    Ms. Parkes, however, twice requested and received CoStar reports
    for the Washington, DC area, one of which included the Woodies Building
    and reflected accurate total size information regarding the building. 19 She
    explained that she requested the reports in order to check the rental rates for
    comparable buildings in the area, but she did not notice that the total size
    represented for the Woodies Building was 524,201 square feet. Tr. 905-906;
    DX 203; DX 206 at 7 (CoStar reports). As she explained, she was only
    interested in what the report revealed for rental rates for other comparable
    commercial buildings in the area in order to compare with what was being
    offered by Mr. Sullivan on behalf of Woodies for the lease extension.
    In February 2014, Mr. Sullivan sent a draft SLA to extend the lease.
    Ms. Parkes reviewed it, made minor edits—none to the tax adjustment
    clause—and circulated the draft SLA to others at GSA prior to execution.
    One document attached to that draft was a General Building Information
    Attachment for the Woodies Building, which stated that the building had 10
    above-grade floors, included the square footage for each floor, and summed
    them up: the “gross area of the building is 516,331 square feet total.”
    PX 74 at USC-CC-00688. Ms. Parkes had no recollection of that
    particular document on the stand, but the parties agree that it was sent by
    her as an attachment to the draft lease extension.
    On March 6, 2014, Ms. Parkes signed Lease 1641 SLA No. 32,
    which extended the lease for two years; Mr. Jemal signed on behalf of
    Woodies. PX 73.
    19
    CoStar is a provider of commercial real estate information; the CoStar
    database is its main product. As Ms. Parkes explained, it is a tool that
    building owners use to market their properties by keeping an up-to-date
    profile for commercial buildings in the database. Tr. 874. All the
    witnesses in this case were familiar with the database, had access to it, or
    could obtain access to it through other persons. Ms. Parkes requested the
    report for the Woodies Building from her Branch Chief, Roger Perrault.
    Tr. 903.
    15
    VI.   GSA Discovers The Issue
    From 2008 to 2012, GSA made tax adjustment payments to Woodies
    as invoiced by Woodies for the leases at issue. The GSA employees who
    authorized those payments relied on the figures stated in the leases. All
    testified that it would have been beyond the scope of their duties to
    independently verify information (other than that on the face of the
    contract) after lease execution. 20 GSA used SLAs to authorize each of the
    tax adjustment payments. 21         GSA stopped making tax adjustment
    payments on all of the leases as of December 13, 2012, after Woodies filed
    suit in an earlier action challenging GSA’s use of a base year different than
    that agreed upon by the parties. PX 72 (email from CO Berelson to
    Woodies); Tr. 1090-91 (Berelson); see Woodies Holdings, L.L.C. v. United
    States, 
    115 Fed. Cl. 204
    , 212-15 (2014).
    In 2014, Gregory Otten, a GSA lease specialist, began working on
    arrangements for the FBI leases in the Woodies Building as they neared
    their conclusion (leases 1751, 1809, and 1838). The idea was to extend all
    three leases so that they would have the same end date to simplify follow-on
    procurements. Tr. 956 (Otten). In March or April of 2014, Mr. Otten
    noticed that the total building size stated on those leases was inconsistent
    with what he had seen advertised online. Tr. 955, 1015, 1019. Mr. Otten
    thus asked for and received a CoStar report for the building and verified
    that it was larger than stated in the leases. Tr. 1024-25. He also took the
    initiative to try to track down the original supporting documents submitted
    20
    The same was heard uniformly from GSA employees working on
    contract formation for these leases. (With the exception of Mr. Otten,
    infra.) None felt they had the time or took the initiative to check the
    accuracy of any figures. All of the contracting officers testified that they
    relied on their contract specialists to ensure accuracy. Lower level
    employees all stated that they relied on the offerors to submit accurate
    information and that it was never their practice to independently verify offer
    information.
    21
    GSA employee testimony was uniform that these were unilateral SLAs
    and did not require a signature from Woodies. Woodies own copies of
    those SLAs are signed. The parties differ as to the relevance of this fact.
    It does not matter to our ultimate conclusion, however.
    16
    by Woodies for the three leases but was unsuccessful because those
    documents had already been sent to the National Archives. Having
    verified the accurate building size, Mr. Otten ensured that the new leases
    included “504,221 BRSF” for the total building size in the tax adjustment
    clause. E.g., PX 85 at 7 (¶ 1.13).
    After Mr. Otten reported his findings to GSA management, he was
    asked to prepare a spreadsheet to compare what GSA paid to what it
    believes it should have paid. This information was provided to the
    contracting officers who worked on the certified claims submitted by
    Woodies for each of the leases. 22 PX 249, PX 250, PX 251, PX 252
    (certified claims). GSA denied each of those claims. DX 175, DX 176,
    DX 177, DX 178, DX 180, DX 181, DX 182 (claim denials).
    VII. Plaintiff’s Prima Facie Case
    It is plaintiff’s burden to first prove its entitlement to damages. We
    find that it has. The tax adjustment and Business Improvement District
    (“BID”) tax clauses are unambiguous. 23 They required GSA to reimburse
    Woodies 12.98% of any increase in those taxes over the base year. The
    base year is not at issue.
    22
    Mr. Otten’s spreadsheets were also provided in discovery to plaintiff.
    This is relevant to when plaintiff received notice of the government’s claim
    of overpayment. Given our conclusion, however, that defendant has not
    proven the defense of unilateral mistake, the issue is moot.
    23
    Defendant believes the interpretation of the BID clause was still
    undecided at the time of trial. To the extent our prior order was unclear in
    that respect, we iterate here that the clauses are nearly identical, use the
    same percentage of occupancy, and operated in the same way. Although
    the BID clauses state that retail space is included in the denominator, we do
    not read the BID clause any differently than the real estate tax adjustment
    clause. Treating the clause as written produces neither an unconscionable
    nor a nonsensical result. See Woodies, 
    2017 WL 6381709
    , at *3. Only if
    the clause is reformed will defendant be relieved of its contractual duty to
    reimburse plaintiff for the stated share of BID tax increases.
    17
    Plaintiff established at trial that it timely submitted invoices for
    the tax adjustment clauses based on the percentage stated in the leases.
    Ms. Shaala Motamedi of Woodies testified regarding her role in preparing
    and sending those invoices. Joel Berelson, a GSA CO, agreed and
    testified that Ms. Motamedi timely sent him invoices for lease 1751
    payments. The parties thereafter stipulated as to the timeliness of the rest
    of the unpaid invoices for the other leases. See Tr. 1093-94. 24 There is
    no dispute that those invoices were not paid.
    Plaintiff also presented the testimony of its expert Cristal Brun.
    Ms. Brun was qualified by the court as an expert in forensic accounting and
    economic damage analysis. Tr. 1604. Ms. Brun reviewed the lease
    documents, invoices from the DC city government to Woodies, Woodies’
    invoices to GSA, and tax refunds received by Woodies from DC. She then
    reconciled the lease years with the DC fiscal year and determined the yearly
    increase of taxes over the base year for each lease. Next, she applied the
    stated percentage of occupancy to each of those figures. To the resulting
    sums, she netted out Woodies’ tax refunds from the city. The remainder
    was GSA’s share of tax increases to be reimbursed under the BID and tax
    adjustment clauses.
    Ms. Brun then applied prompt payment interest for one year and then
    simple interest thereafter on each amount. She added these sums to the
    balance due for each lease as of April 25, 2018. The last step of Ms.
    Brun’s calculus was to calculate a daily interest rate for each of those
    amounts that can be applied to bring them forward to the date of judgment.
    It should be noted that Ms. Brun also calculated what the sums would be if
    prompt payment interest were not available. The figure, with prompt
    payment interest, as of April 25, 2018, was $3,427,515.96 for all leases.
    Tr. 1658-59. None of this testimony was controverted and, other than the
    applicability of prompt payment interest, not disputed by defendant, except
    for its affirmative defense. We consider the issue of interest later, but
    otherwise find that plaintiff has proved a claim for damages for unpaid tax
    adjustment payments.
    24
    The invoices themselves are also in evidence: PX 90 to PX 97 for lease
    1751; PX 98 to PX 105 for lease 1805; PX 106 to PX 114 for lease 1838;
    and PX 115 to 20, PX 122 to 152, and PX 139-145 for Lease 2154.
    18
    DISCUSSION
    We are thus presented with plaintiff’s established claim for
    approximately $3.5 million plus additional interest to the date of judgment.
    In the absence of an affirmative defense, it is entitled to judgment.
    Defendant’s answer is that Todd Valentine, and later Kirkland Williams,
    were mistaken when they inputted 372,990 square feet into the leases as the
    total building size for the BID and tax adjustment clauses. Defendant also
    avers that Mr. Jemal, Woodies’ principle, and Mr. Gregorowicz, Woodies’
    agent, were aware of this mistake when lease 1641 was entered into and
    subsequently for each of the other leases as well. The government thus
    asks the court to reform the contracts to correct those provisions to reflect
    an accurate percentage of occupancy. Defendant has also counterclaimed
    for amounts it believes it overpaid prior to ceasing payment in 2012.
    Reformation of a written contract is an “extraordinary remedy.”
    Nat. Australia Bank v. United States, 
    452 F.3d 1321
    , 1329 (Fed. Cir. 2006).
    It is generally only available on a showing by clear and convincing evidence
    that the intent of the parties is not expressed by the written instrument,
    which is to say that the parties both made the same mistake of fact. See 
    id. “Reformation will
    not be granted, unless the proof of mistake be ‘of the
    clearest and most satisfactory character.’” Philippine Sugar Estates Dev.
    Co. v. Gov’t of Philippine Islands, 
    247 U.S. 385
    , 391 (1918) (quoting Snell
    v. Atlantic Fire & Marine Ins. Co., 
    98 U.S. 85
    , 89 (1878) (explaining the
    common law standard of clear and convincing evidence necessary to reform
    a contract)). Where, as here, the mistake alleged is not mutual, the law
    requires the unmistaken party to have known, or have had reason to know,
    of the other party’s mistake. Burnett Elecs Lab., Inc. v. United States, 
    202 Ct. Cl. 463
    , 479 (1973). Otherwise, reformation on the basis that only one
    party made a mistake is unavailable. See Cheyenne-Arapaho Tribe of
    Indians v. United States, 
    671 F.2d 1305
    , 1311 (Ct. Cl. 1982); Horn &
    Assocs. v. United States, 
    104 Fed. Cl. 121
    , 131 (2012). 25
    25
    Cheyennne-Arapaho and a line of similar earlier cases out of the Court of
    Claims generally held that unilateral mistake will not support a claim for
    reformation. 
    Cheyenne-Arapaho, 617 F.2d at 1311-12
    (citing Callen v.
    Penn. R. R. Co., 
    332 U.S. 625
    , 630 (1948)); Albano Cleaners, Inc. v. United
    States, 
    455 F.2d 556
    , 560 (Ct. Cl. 1972); Allied Contractors, Inc. v. United
    States, 
    310 F.2d 945
    (Ct. Cl. 1962). This rule was followed by the Federal
    Circuit in American Employers Insurance Co. v. United States, 
    812 F.2d 19
           Thus, defendant must show by clear and convincing evidence that
    GSA 1) made a mistake, not having borne the risk of that mistake, as to a
    basic assumption on which it made the contract; 2) that its mistake had a
    material effect on the agreed exchange of performance; and 3) either the
    result is unconscionable, or Woodies knew or had reason to know of it.
    Johnson Mgmt. Group CFC, Inc. v. Martinez, 
    308 F.3d 1245
    , 1260 (Fed.
    Cir. 2002) (citing the Restatement’s formulation of the test for unilateral
    mistake); Woodies, 115 Fed. at 214 (citing Northrop Grumman Corp. v.
    United States, 
    47 Fed. Cl. 20
    , 91 (200).
    I.   GSA Was Mistaken in Leases 1641, 1751, 1809, and 1838
    The first element that defendant must prove is that GSA made a
    mistake that it did not bear the risk of and that the mistake went to a
    fundamental assumption on which the contract was made. We first
    examine leases 1751, 1809, and 1838. Lease 2154 is treated separately.
    A. Todd Valentine Made a Mistake
    Mr. Valentine testified that, although he could not specifically recall
    how or why, he made a mistake when inserting the 372,990 figure into the
    tax adjustment clause of Lease 1641. He does not recall specifically
    where he pulled that number from, and he confirmed that Woodies’
    submissions leading to lease 1641 contained accurate information for the
    total building size. He made a reasoned guess, when asked during trial,
    700, 705 (Fed. Cir. 1987) (holding that fraud or misrepresentation is
    necessary to overcome the presumption against reformation for a unilateral
    mistake). An exception to this rule in the Court of Claims was allowed in
    the case of mistaken bids, where the winner of a contract with the federal
    government alleged that it was, in essence, taken advantage of when the
    Contracting Officer knew of a mistake that the bidder had made but
    accepted the offer anyway. E.g., Wender Presses, Inc. v. United States,
    
    343 F.2d 961
    , 962 (Ct. Cl. 1965). This court has followed that line of
    cases, citing the modern restatement’s formulation of the test. E.g., Nat.
    Rural Utils. Co-op Fin. Corp. v. United States, 
    14 Cl. Ct. 130
    , 141 (1988)
    (citing Restatement (Second) of Contracts § 153 (1981)). This includes
    adopting it as an affirmative defense to a contractor’s breach claim. See,
    e.g., Ameriserv Tr. v. United States, 
    125 Fed. Cl. 733
    , 747 (2016).
    20
    that he pulled that number from the Form 1364 submitted by Woodies and
    had not realized that the figure was for office space alone despite the fact
    that significant retail space was reflected in close proximity on the same
    page of the document. See DX 5 at 6; DX 6 at 8. Nowhere else does that
    figure appear in the documents that lead to lease 1641. Neither he nor
    anyone else at GSA who reviewed the lease prior to its execution caught the
    error. 26 The initial mistake was then replicated for leases 1751, 1809, and
    1838. Mr. Valentine testified that he cut and pasted the 372,990 figure
    from lease 1641 into those leases since they were all virtually identical
    contracts (each covering an identical floor of the building). It was not his
    testimony that he relied on Woodies’ separate submissions for those leases
    in selecting the smaller total building size number for the subsequent leases.
    We thus find no affirmative misrepresentation on Woodies’ part.
    Defendant points to the testimony of each of the GSA personnel
    involved with these leases that, as far as they knew, GSA had never
    knowingly excluded retail space from an office space lease. Each was also
    asked whether they knowingly chose to exclude the retail space from the
    leases at issue. That answer was also uniformly “no.” They all believed
    that 372,990 represented the entirety of the building. Tr. 384-86, 389-91
    (Sutton discussing leases 1751, 1809, and 1838); Tr. 465-66 (Graham
    discussing SLA No. 1 of Lease 1838); Tr. 518-20 (Williams discuss lease
    2154); Tr. 569-70, 572 (Parrish discussing lease 2154); Tr. 851 (Parkes
    discussing SLA No. 32 for lease 1641). Further, 10 current and former
    GSA employees affirmatively stated that GSA’s policy or practice had been
    to include retail space. Tr. 246-47 (Valentine); Tr. 389, 393-94 (Sutton);
    Tr. 439, 459 (Graham); Tr. 532 (Williams); Tr. 569-70 (Parrish); Tr. 844
    (Parkes); Tr. 962 (Otten); Tr. 1070 (Berelson); Tr. 1300-1303 (Lynch); Tr.
    1351 (Mowery).
    26
    Testimony at trial established that the leases were, or should have been,
    reviewed by GSA attorneys, by the Data Accuracy Group within GSA, and
    by the COs who signed them prior to execution. These individuals all—save
    Mr. Otten—testified, however, that it would have beyond the scope of their
    duties, or beyond their ability due to workload, to confirm or verify any
    information provided in the standard lease forms. Thus, the proverbial
    “buck” gets passed down to Mr. Valentine as the only person who testified
    that he handled the papers submitted by Woodies. Everyone else simply
    assumed that someone else with more time and attention had done so.
    21
    Plaintiff attempted to cast doubt on these GSA statements by asking
    Mr. Gregorowicz, who had been a GSA attorney prior to his private
    practice, whether GSA ever purposely excluded retail space from its
    calculation of total building size. Mr. Gregoworicz testified that there was
    no uniform policy and that it was dealt with on a “case by case basis.” Tr.
    641. This testimony was echoed by Arthur Turowoski, a former GSA
    Director of Leasing Policy and Performance for the National Capital
    Region. We accepted him as an expert in GSA federal leasing policy and
    practice. 27 Tr. 1475. Mr. Turowoski testified that GSA did exclude retail
    or other space from total building size calculations when it made sense to
    do so. If a building had a portion that had little value or that would not
    function as office space, it might be excluded from the percentage of
    occupancy calculation. Tr. 1481-88. There was no set policy against
    excluding portions of a building, and GSA handled buildings on a “case by
    case” basis, was Mr. Turowski’s recall. Tr. 1488.
    Although we are presented with conflicting testimony regarding
    GSA’s policy at the time, GSA witnesses were unanimous in stating that
    they had not knowingly excluded the retail space from the percentage of
    occupancy calculation in these leases and none of them were aware of the
    mistake prior to Mr. Otten’s discovery. We found this testimony credible,
    and it was unrebutted. We thus find that there was a mistake made by
    GSA in lease 1641, including the two-year extension, which was repeated in
    leases 1751, 1809, and 1838. We will treat lease 2154 separately below.
    B. GSA Bore the Risk of That Mistake
    Plaintiff argues that GSA bore the risk of that mistake by consciously
    disregarding information that it had at hand. There is no question that Mr.
    Valentine and all of his superiors at GSA had readily available to them the
    accurate building size information submitted by Woodies prior to executing
    lease 1641.       Although the forms submitted along with Woodies’
    27
    Although we accepted Mr. Turowoski as an expert, his testimony on the
    matter was more in the nature of a fact witness. He was the director at the
    time these leases were entered. He did not specifically work on the leases
    at issue, but his testimony regarding the general policy of GSA is something
    of which he had firsthand knowledge rather than as expert opinion after the
    fact.
    22
    subsequent offers for the other leases used only the 372,990 number, Mr.
    Valentine testified that he simply copied lease 1641 for those leases. In
    addition, other supporting information with those offers contained accurate
    figures for the entire building. Thus, GSA was not led astray by an
    affirmative misrepresentation by Woodies in the later leases.
    Plaintiff also argues that Mr. Valentine, and each of the contracting
    officers after him, could have checked CoStar and any of Woodies’
    submitted building information (BOMA charts and Fire Safety Documents)
    that contained the accurate total size. They all admitted so on the stand.
    Indeed, Mr. Otten demonstrated that it was relative child’s play, assuming
    one were curious, to discover the error. In addition, plaintiff points out
    that many of the GSA personnel directly involved toured the Woodies
    Building—Mr. Valentine on multiple occasions—and could not have
    missed the fact that several floors were reserved for retail tenants.
    We also accept Mr. Gregorowicz’s testimony that he would have had
    a discussion with someone at GSA about whether to include retail space in
    the figures for total building size when the SFO form changed, first,
    specifically indicating that retail space included in total size, and later,
    when a revised SFO 00-011 omitted any reference to retail. See Tr.
    684-85. Compare PX 13 at EVG-002195 (§ 2.4(e)) (original SFO 00-011)
    with DX 3 at 5 (§ 2.4(f)), 24 (§ 2.4(f)) (revised SFO 00-011). All of the
    subsequent SFOs at issue here also omitted any reference to retail space
    when referencing the total building size for tax adjustment purposes. See
    PX 16 (SFO 02-001); PX 19 (SFO 02-019); PX 21 (SFO 04-005); DX 63
    (SFO 07-014). Mr. Gregorowicz testified that the lines of communication
    were open between him and Mr. Smale during this time frame and that this
    was something that he would have raised with GSA before submitting a
    final offer. Tr. 685-86. When asked during trial how he would have read
    the revised SFO 00-011’s tax adjustment clause, Mr. Gregorowicz testified
    that he would have read it as including office space only. Tr. 685.
    In plaintiff’s view, the court should view GSA’s practice with these
    leases as having assumed the risk of conscious ignorance of relevant
    information regarding the size of the Woodies Building. Defendant
    responds that there is no evidence of a risk allocation to the government
    either in the contract itself or in the government’s conduct.
    23
    The Restatement instructs that, to establish the defense of unilateral
    mistake, the asserting party must show that it did not bear the risk of that
    mistake, either by having allocated that risk to itself in the contract or by
    proceeding despite being aware that it had only limited knowledge about the
    facts related to the mistake. Restatement (Second) of Contracts § 154
    (1981). Plaintiff points to the second prong, arguing that the lack of
    diligence of GSA employees and the fact that Woodies submitted all the
    information necessary before lease 1641 was executed are sufficient to
    show that GSA disregarded its limited knowledge of the facts of the
    building. In substance, we agree with plaintiff. Although, in this
    instance, the government had all the information it needed, it simply moved
    forward without paying attention to it.
    The record is clear that Woodies presented accurate information to
    GSA prior to the execution of lease 1641. It is also clear that no one at
    GSA was particularly concerned with the tax adjustment provision (nor the
    total building size). Despite the significant potential impact of tax
    increase allocations, GSA’s focus was exclusively on rental rates. Todd
    Valentine stated that he would have reviewed some of the information
    relevant to the tax adjustment clause, the Form 1364 and 1217, but other
    supporting information, such as BOMA charts and general building
    information sheets, he did not review. Tr. 273. He also did not review
    any information about the Woodies Building in CoStar despite being very
    familiar with it, having worked for CoStar previously.
    To be sure, box 3(a) on the Form 1364 submitted by Woodies along
    with its offer lists 372,990 for the office space. As discussed above, we
    can infer, as Mr. Valentine did on the stand, that is the source for the figure
    for total building size. Woodies’ Form 1217 also listed only 346,081 as
    usable square feet for the building. Although Mr. Gregorowicz discussed
    why that number was used, as we will treat in more detail below, the
    presence of that number in the Form 1217 is consistent with using 372,990
    for the total rentable size of the building because “usable” square footage
    was always smaller than “rentable” square footage. The genesis of the
    mistake is thus understandable, but that does not excuse GSA’s negligence
    in wholly relying on Mr. Valentine, who ignored multiple sources of
    accurate information that would have disabused him of his notion that the
    building was only 372,990 square feet in total. Further, when asked about
    why the smaller numbers used did not ring any alarm bells for him, Mr.
    Valentine admitted that using the 372,990 and 346,081 figures would result
    24
    in a “core factor” of roughly seven percent, an unusually efficient result for
    a building of this type. 28 Tr. 366. When asked whether that should have
    “been a big red flag” if he believed those numbers to be accurate, Mr.
    Valentine affirmed that such a core factor should have alarmed him. 
    Id. (“definitely, yeah”).
    Woodies’ submissions in response to SFO No. 00-011 included
    BOMA charts, a building summary, fire safety information, and CAD
    drawings, all of which included accurate total building size numbers. All
    of the SF-2s and Form 1364s also included that information, although some
    minimal arithmetic might have been necessary depending on which page
    one viewed. Compare DX 5 at 6 (box 3(a) plus box 3(c)) with DX 5 at 8
    (listing separate figures for office and retail and a total figure of 512,230
    BRSF). Additionally, Woodies advertised the total building size on
    CoStar, which numerous GSA employees had access to and were familiar
    with. This is too great a volume of accurate information to ignore, and yet
    that is what GSA did.
    Mr. Valentine reviewed only a limited subset of Woodies’
    submission documents (Form 1364s and 1217s) and ignored many readily
    available sources of accurate information despite using total building
    numbers that, by his own admission, should have set off a red flag. The
    contracting officers involved did not review the underlying lease documents
    nor did anyone else at GSA because they relied on Mr. Valentine having
    done so. Those with authority to bind GSA legally were aware that they
    had no personal knowledge and had not reviewed any supporting
    information to confirm the accuracy of the figures to which they were
    binding the government. No matter from whose perspective the facts are
    viewed, from Mr. Valentine’s or from his superiors’, GSA personnel were
    content to ignore accurate information provided by plaintiff.
    In the final analysis, defendant’s error was the result of Mr.
    Valentine’s cavalier and careless approach to his work, compounded by the
    28
    Mr. Valentine explained earlier in his testimony that the core factor of a
    building was the percentage of usable space against the rentable space.
    The lower the percentage, the more “efficient” a building was from the
    landlord’s perspective. Tr. 310-12. In his experience, a typically efficient
    building had a core factor of 10 to 12 percent. Tr. 311. Thus, seven
    would have been an outlier.
    25
    equally careless oversight of his superiors, which in turn was facilitated by
    the agency’s compartmentalization of tasks regarding lease development
    and oversight, as well as its constantly evolving forms and terminology.
    Numerous employees testified, in effect, that assuring accuracy, beyond
    merely looking at what the lease stated, was not in their job description.
    Only one of them, Mr. Otten, by exercising some diligence, was able easily
    to spot the inconsistency in the building size descriptions. This is
    precisely the sort of “conscious ignorance,” or gross negligence, that the
    law will not countenance when a party seeks to avoid its contractual
    obligations by claiming it was mistaken. See Restatement (Second) of
    Contracts § 154, cmt. c; see also Griffin & Griffin Exploration, LLC v.
    United States, 
    116 Fed. Cl. 163
    , 175 (2014).
    C.   The Total Building Size Was a Basic Assumption
    Lastly, with regard to this issue, defendant must establish that the
    mistake concerned a basic assumption upon which the contract was formed.
    Defendant argues that the tax adjustment clause is part of price, which is
    always part of the basic assumption on which a contract is made. We
    agree.
    Plaintiff argues that, because the tax adjustment provision was not
    set until after Woodies had been selected as an offeror, it could not have
    formed any part of the basis of the bargain between the parties. We
    disagree. An additional payment from one party to the other, even if its
    accuracy is not of particular concern to one party, is part of the price term of
    the lease. The mistake as to the building’s total size does go to a basic
    assumption on which the deal was struck because it was relevant to the total
    price, after the operation of tax adjustment clauses, that defendant would
    ultimately end up paying for the lease. Thus we conclude that, as to leases
    1641, 1751, 1809, and 1838, defendant made a mistake, as to which it bore
    the risk, with respect to a basic assumption on which the contract was made.
    D. Lease 2154
    We reach a different conclusion as to lease 2154. For this lease, we
    find no mistake in the first instance. We find credible Mr. Gregorowicz’s
    testimony that he called someone at GSA, most likely Mr. Williams, to
    discuss the building size because he had previously omitted retail space.
    Although, at trial, Mr. Williams did not recall having spoken with Mr.
    26
    Gregorowicz, he did confirm that the AAAP produced forms that included
    zero for retail space in the Woodies Building.
    Mr. Gregorowicz’s testimony on the matter was direct and credible,
    and it comports with his earlier testimony that he would have called GSA to
    discuss the changes in the SFO when it omitted a reference to retail space.
    His testimony was also in harmony with that of Mr. Lynch, who testified
    that, under the AAAP, the lines of communication between offerors and the
    agency were open. Mr. Gregorowicz was an experienced real estate
    attorney with significant experience as an agent and attorney dealing with
    GSA. His having keyed in on the importance of including, or not, the
    retail space for the Form 1364, and by extension for the total building size,
    is consistent with that experience.
    We also find an inherent consistency in Mr. Gregorowicz’s
    testimony regarding his actions relating to the issue of retail space across
    these leases. He testified that GSA had no consistent policy of including it,
    that it was rare to see it in office buildings in the downtown DC area at the
    time, that he was concerned with it when saw a change in the SFO that
    excluded any reference to it, and was then concerned again when he was
    prompted to input total building size when submitting an offer under the
    AAAP. It is no surprise then that Mr. Gregorowicz was concerned with the
    inclusion, or not, of retail space in 2009 for lease 2154 because, as detailed
    above, significant retail activity had begun by that point in the Woodies
    Building. 29
    Although we found Mr. Williams generally credible, his testimony
    was less specific. His inability to recall having spoken with Mr.
    Gregorowicz does not rebut Mr. Gregorowicz’s affirmative testimony on
    the point. Mr. William’s testimony that he believed 372,990 accurately
    reflected the total size of the building is also not directly contradictory to
    Mr. Gregorowicz’s statement. If the two (or someone else at GSA) had
    discussed not including retail space for the Woodies Building, then his
    answer at trial that he believed the number used in the lease to be accurate
    is not an indication that he was mistaken.
    29
    We do note that Mr. Jemal testified that most of the value was in the
    office space even when lease 2154 was signed, but it is also clear that
    significant retailers were in place in the building by the time that lease was
    entered into.
    27
    We also know that the CO, Michelle Parrish, was not concerned with
    the accuracy of that number. Although she testified that she never
    knowingly omitted retail space from a total building size, Tr. 569-70, she
    went on to admit that she was aware of the retail activity in the building,
    Tr. 573. She was not alarmed, however, that Woodies’ offer stated zero
    retail space because she recalled conversations that she had had with Mr.
    Jemal, and possibly Mr. Gregorowicz, regarding a separate tax assessment
    of the retail space from the office space in the building. Tr. 574-76.
    Although she walked back her recollection regarding when these
    discussions took place, after a series of leading questions from her counsel,
    we think her testimony in this regard is instructive that she was not making
    a mistake when signing the lease with 372,990 listed for the total building
    size. 30 Thus, we find, as to lease 2154, that defendant has not proven by
    clear and convincing evidence that GSA was mistaken when it entered that
    lease.
    II.   The Mistake Was Material
    We hold that the mistakes as to leases 1641, 1751, 1809, and 1838
    did have a material effect on the agreed upon exchange of performance.
    Having held that the tax adjustment clause and BID clause were part of the
    price term, it is undeniable that the mistake was material. Having a higher
    percentage of occupancy than defendant would otherwise have agreed to,
    means that it paid a greater percentage of tax increases and thus a higher
    price overall. That constitutes a material effect on the agreed upon
    exchange of performance.
    30
    Although the office space and retail space never were separately assessed
    by the DC taxing authorities, this still shows a clear indication in Ms.
    Parrish’s memory that there was something peculiar with this building as it
    regards the relationship between retail and office space. This suggests to
    the court that she had reason not to be concerned with the omission of the
    retail space from the total building size and may have done so intentionally.
    Although we do not find that GSA affirmatively decided to do so, it is
    defendant’s burden to establish the opposite, and as to lease 2154, we
    conclude that it has not.
    28
    III. Woodies’ Knowledge
    We come finally to whether Woodies had knowledge of the mistake.
    In order for the defense to succeed, plaintiff, the unmistaken party, must
    have known of defendant’s mistake or had reason to know of it.
    Defendant believes this factor is clearly established by the testimony of
    Mssrs. Jemal and Gregorowicz, both of whom admitted to knowing, at the
    time the leases were entered, that the Woodies Building was far larger than
    372,990 of rentable square feet. Thus, defendant asserts, they knew the
    government was stepping on a landmine and, instead of warning it,
    remained silent. Plaintiff responds that Woodies, and more specifically
    Mr. Gregorowicz, believed that GSA had accepted that number for the total
    building size because it represented the office space in the building, the
    only space the lease was concerned with, and because Mr. Gregorowicz
    raised the issue with GSA prior to lease 1641 and again prior to lease 2154.
    There is no dispute that Woodies knew the building’s actual size was
    approximately 500,000 square feet, inclusive of retail, but Mr. Gregorwicz
    testified that he believed that GSA had changed the SFO to exclude retail
    space for the tax adjustment clause, and, not only did he believe that, but he
    would have also called or met with someone at GSA, likely Mr. Smale, to
    clarify. The evidence on this point is close, but because defendant bears
    the burden to prove plaintiff’s knowledge by clear and convincing evidence,
    we find that it has not met that burden.
    A.   Leases 1641, 1751, 1809, and 1838
    As stated above, when asked by defense counsel what he believed
    the tax adjustment clause to have meant when the revised SFO 00-011 was
    issued by GSA, Mr. Gregoworicz stated: “since there was no longer a
    reference to retail space in this, it could have been that they were going
    back to that definition of just office space.” Tr. 685. It was his testimony
    that GSA had omitted retail space from the building size in the past. He
    continued:
    But I will tell you this: I would have likely have called and/or
    spoken to the contracting officer about why there was a
    change and what the intent was. I wouldn’t have just relied
    on my own judgment for what it meant. There was an open
    dialogue between myself and the contracting officer, not only
    29
    in terms of understanding these things, but in the discussion
    we had between initial offer and best and final offer . . . .
    
    Id. The court
    then asked whether he had a specific recollection of noticing
    that change and having a conversation with GSA about it. He answered
    that he could not specifically recall either “sitting here today all these years
    later . . . , but when a document changed from what it was to this, it would
    have certainly drawn my attention as to why it changed, and I am sure that I
    would have followed up.” Tr. 686.
    Balanced against that testimony we have GSA employees’ universal
    responses to the question of whether they omitted retail space purposefully
    (“no”), and no one involved with Lease 1641 could recall having spoken to
    Mr. Gregorowicz about the issue, but all were sure that they would not have
    omitted retail space.
    The question that naturally arises when faced with these competing
    recollections is what purpose the parties could have had in agreeing to omit
    retail space. Defendant naturally avers that it could not have had any
    purpose in doing so. Plaintiff, however, offered some relevant testimony
    on the issue. Mr. Gregorowicz was asked to explain the approach that he
    took in filling out the Form 1217 (breakdown of lessor’s costs) in response
    to the SFO that led to lease 1641. The Form 1364s submitted by Woodies
    prior to lease 1641 all had included a breakdown of space that included
    numbers for retail space. On the Lessor’s Annual Cost Statement,
    however, Mr. Gregorowicz explained that he purposefully omitted the retail
    space because retail tenants did not pay any share of the lessor’s costs for
    cleaning or utilities. Retail lessees paid their own cleaning costs. GSA
    also required daytime cleaning operations in its leased space, which
    represents a higher operating cost not shared by space rented to other
    private entities. Tr. 653-54. Thus, in order to represent an accurate
    figure for the costs per square foot to GSA, Mr. Gregorowicz purposefully
    omitted the retail space. Tr. 653-54, 790, 801-803. He also testified that
    he would have explained this to Mr. Smale because the presence of
    significant retail space in the Woodies Building was different from the
    normal experience at that time for GSA in the National Capital Region.
    Tr. 803-804.
    Excluding from the Form 1217 space that did not contribute to
    Woodies’ costs to operate the building, and especially the area to be rented
    30
    by the government, was important to plaintiff because, as Mr. Gregorowicz
    explained, GSA wanted to know what it would cost to operate the space that
    it would be renting. The cost to operate was a component of the rent. Tr.
    652. This was confirmed by Mr. Sutton. Tr. 387 (stating that the
    purpose of the Form 1217 was to show the cost to operate the building and
    specifically the “GSA leased area on a square foot basis”). Retail space
    had a different cost and reimbursement structure. It thus made little sense
    to Woodies to include it in the form 1217. This is a plausible explanation,
    and we find Mr. Gregorowicz to be a credible witness and thus take his
    statements in this regard at face value.
    Mr. Gregorowicz explained that the Woodies building was unique in
    downtown Washington during this time because it contained substantial
    retail space, something of an anomaly at the time. Tr. 658-59. That
    statement was confirmed by Mr. Smale, Mr. Jemal, and Mr. Valentine. Tr.
    128, 659, 1167. Mr. Jemal further explained that retail space in downtown
    Washington, DC during the late 1990s and early 2000s was a “morgue” and
    had been “redlined” by retailers as an area to avoid. Tr. 1167-68, 1192-94.
    Although redevelopment of the Woodies Building into a mixed retail and
    office building was highly valued by the DC administration, retail initially
    was a drag on the project. Tr. 1167-68. In order to attract retailers,
    Woodies undertook significant publicity and advertising of the space.
    The first retail vendor lured to the building by Woodies was H&M in
    2002. See PX 130 (H&M lease). Williams and Sonoma was next in 2006,
    Zara in 2007, Madam Tussaud’s in 2007, and Forever 21 in 2008. See PX
    134; PX 135, PX 136, PX 137 (retail leases).
    Despite the eventual success in enticing retailers to the Woodies
    Building, in late 2002, the success of that effort was no foregone
    conclusion. Mr. Jemal thus explained that Woodies’ approach to the lease
    with GSA was that the value was in the office space; there was not yet any
    significant value in the retail space. Tr. 1190. [
    ]. This is evidence, in plaintiff’s view, of the merit of its claim that it did
    not, at least at the time of lease 1641, value the retail space as contributing
    meaningfully to the value of the Woodies Building. Plaintiff points to
    31
    these facts as reasons why Mr. Jemal was not surprised to learn that GSA
    was willing to accept the smaller building size number.
    After lease 1641, Woodies believed the issue of retail space was
    resolved as not being included in the total building size and thus did not see
    necessary the need to include retail space in the Form 1364s in response to
    the SFOs after lease 1641 was formed. We explained above why it did not
    do so with regard to the Form 1217s that it submitted.
    We are thus left with plaintiff’s plausible explanation for why it had
    no reason to think that GSA was making a mistake with regard to leases
    1641, 1751, 1809, and 1838. On the other hand, we have the testimony of
    government employees that they did not mean to omit the retail space and
    did not recall having spoken with anyone at Woodies regarding the issue.
    That is insufficient to bridge the gap to find for the government. The
    burden on defendant is to establish Woodies’ knowledge by clear and
    convincing evidence. In the face of plausible competing evidence,
    defendant is well short of establishing that Woodies knew or should have
    known that GSA was making a mistake.
    B. Lease 2154
    The conclusion is the same as to lease 2154. Although we hold that
    defendant has not established the predicate mistake, it is worth noting that,
    even if we found a mistake to have been made with Lease 2154, Mr.
    Gregorowicz’s testimony that he called GSA to discuss the issue of retail
    space would, in the absence of other damning evidence, preclude a finding
    that Woodies knew or should have known that GSA was making a mistake.
    In sum, although we are satisfied that defendant has proven by clear
    and convincing evidence that a mistake was made as to the total building
    size listed in leases 1641, 1751, 1809, and 1838, we find that defendant
    bore the risk of that mistake because it ignored too great a volume of
    accurate information and was not misled by plaintiff. As to lease 2154, we
    find that no mistake was proven. As to all of the leases, we find that
    plaintiff lacked the requisite knowledge of the mistake. Plaintiff is
    therefore entitled to all of the withheld real estate and BID tax adjustment
    payments.
    32
    IV.   Interest
    Plaintiff’s entitlement to damages having been established, we turn
    to its claim for interest. There is no dispute that plaintiff is entitled to
    simple interest for the amounts due under the lease pursuant to the Contract
    Disputes Act (“CDA”) and the applicable clauses in the leases, which read:
    “The Government shall pay interest on the amount found due and unpaid
    from (1) the date that the Contracting Officer receives the claim (certified,
    if required); or (2) the date that payment otherwise would be due, if that
    date is later, until the date of payment.” DX 44 at 110 (Lease 1751); DX
    49 at 108 (Lease 1809); DX 51 at 110 (Lease 1838); DX 70 at 83 (Lease
    2154). Plaintiff’s expert used this clause to apply CDA interest from the
    date of the initial certified claim and then from the date of any amounts due
    that arose after the date of the certified claim. Defendant, in its
    supplemental brief, offered that CDA interest could be calculated on the
    whole amount, including amounts that came due after the certified claim, as
    of the date of the claim to the CO.
    Plaintiff also claims it is owed Prompt Payment Act interest for the
    first year that each amount was owed it under the lease. The contracts
    provide:
    An interest penalty shall be paid automatically by the
    Government, without request from the Contractor, if payment
    is not made by the due date . . . . The interest penalty shall
    accrue daily on the payment amount approved by the
    Government and be compounded in 30-day increments
    inclusive from the first day after the due date through the
    payment date.
    DX 44 at 101; DX 49 at 99; DX 51 at 101; DX 70 at 73. The parties agree
    that this refers to the Prompt Payment Act, which requires agencies to pay
    an “interest penalty to the concern on the amount of the payment due”
    compounded every 30 days until payment is made, up to a year. 31 U.S.C.
    § 3902-907 (2012). The interest rate is set by the Secretary of the
    Treasury pursuant to 41 U.S.C. § 7109 (2012). 
    Id. § 3902(a).
    Plaintiff’s expert, Ms. Brun, calculated the interest owed with one
    year of Prompt Payment interest and without it. Defendant argues that no
    Prompt Payment interest is owed because the Act does not require a penalty
    33
    “on a payment that is not made because of a dispute” between the parties to
    a contract. 31 U.S.C. § 3907(c). “A claim related to the dispute, and
    interest payable for the period during which the dispute is being resolved,”
    are subject to the normal CDA interest provisions. 
    Id. Plaintiff avers
    that, as of the date that GSA began withholding payment, there was no
    dispute regarding the percentage of occupancy of the building; GSA had
    stopped paying due to its erroneous belief that the base year had not been
    established, a claim that the court rejected in February 2015.
    Alternatively, plaintiff claims that, even if the percentage of occupancy was
    in dispute, the percentage of that payment that the government admits was
    owing should have Prompt Payment Act interest applied to it.
    We find that the Prompt Payment Act is inapplicable under these
    circumstances. Section 3907 plainly exempts any amounts owed during
    the pendency of the base year dispute. After judgment was entered in case
    12-59 on February 10, 2015, GSA continued to withhold tax adjustment and
    BID tax payments, prompting plaintiff to submit its certified claim to the
    CO on March 4, 2015, which GSA denied by written decision on August
    10, 2015, citing the base year and the incorrect building size as reasons for
    non-payment. Although lease 1809 no longer had a base year dispute
    when the CO’s final decision was issued, that dispute having been resolved
    prior by this court’s judgment in February 2015, the decision reveals that a
    dispute over the percentage of occupancy persisted during the lease for that
    period. We thus find Prompt Payment Act interest inapplicable for any of
    the payments at issue here. 31
    We do find, however, that CDA interest is applicable to the entire
    amount that GSA failed to pay from the date of the initial certified claim in
    2015 until the date of judgment. That approach is simpler, supported by
    the case law, and agreed to by defendant, although not yet calculated by Ms.
    Brun.
    31
    We are not aware of any support for the notion that the court should filet
    the tax adjustment and BID clause invoices to apply Prompt Payment Act
    interest to the amounts the agency agreed it should have paid under its view
    of those clauses. The agency is not required to make two payments in
    order to protect itself against prompt payment interest.
    34
    CONCLUSION
    Plaintiff has proven its entitlement to real estate tax adjustment and
    BID tax payments from 2012 forward for all of the leases at issue.
    Defendant has not proven by clear and convincing evidence its defense of
    unilateral mistake. Plaintiff is entitled to simple CDA interest on the sum
    of all of GSA’s missed payments from March 4, 2015 to the date of
    judgment. Accordingly, the parties are directed to confer and propose an
    amount for judgment, or their respective positions regarding the amount for
    judgment, consistent with this opinion in a status report to be filed on or
    before June 21, 2019.
