    OPINION AND ORDER
    KAPLAN, Judge.
    Since 1998, Plaintiff The Boeing Company (Boeing), along with its successor-in-interest,
    Plaintiff United Launch Services (ULS), has contracted with the United States Air Force to
    provide rocket launch services for the government using Boeing’s Delta IV launch vehicle.1 In
    this action, Boeing asserts that the government has breached certain agreements it entered in
    2006 and 2008, when the parties restructured Boeing’s Delta IV launch contracts. The
    agreements in question concern the government’s obligation to make payments related to two
    sets of costs that Boeing incurred prior to 2006. For accounting purposes, Boeing had deferred
    *
    This opinion was previously issued under seal on August 29, 2018. The parties were given the
    opportunity to propose redactions on or before September 12, 2018. Because the parties have
    notified the Court that they do not have any proposed redactions (ECF No. 137), the Court
    resissues its decision without redactions.
    1
    The Court refers to Boeing and ULS collectively as “Boeing” throughout this opinion.
    these costs when it incurred them for allocation to anticipated future launches by holding them in
    inventory as an asset.
    The government asserts that these agreements cannot be enforced because they are
    contrary to the government’s cost accounting standards (CAS), which apply to the restructured
    contracts, and to the FAR. This claim centers on a contention that the accounting practices
    Boeing employed in deferring the costs were required to, but did not, comply with generally
    accepted accounting principles and practices (GAAP).
    Boeing has now moved for summary judgment on its breach-of-contract claims. The
    government, for its part, contends that summary judgment is inappropriate because factual
    disputes exist regarding whether deferring the costs complied with GAAP and thus whether they
    are lawfully payable under the restructured contracts. For the reasons discussed below, the Court
    agrees with the government. Accordingly, Boeing’s motion for summary judgment is DENIED.
    BACKGROUND2
    I.     Initiation of the EELV Program and Early Acquisition History
    A.      Historical Context
    Since the advent of the space age, the United States has consistently viewed access to
    space as a key strategic objective, and has long partnered with private industry to develop the
    launch vehicles needed to attain space access. See Ray A. Williamson, Access to Space: Steps to
    the Saturn V, in Exploring the Unknown Vol IV: Accessing Space 6–10 (John M. Logsdon ed.,
    1999), https://history.nasa.gov/SP-4407/vol4/cover.pdf. The origins of the dispute in this case
    can be traced back to 1994, when, in an update to the National Space Transportation Policy, the
    president called for “the improvement and evolution of the current U.S. expendable launch
    vehicle (ELV) fleet.” White House Office of Science and Technology Policy, Fact Sheet –
    Statement on National Space Transportation Policy (Aug. 5, 1994), https://clintonwhitehouse3.
    archives.gov/WH/EOP/OSTP/other/launchstfs.html. In particular, the president directed “the
    DoD, in cooperation with the civil and commercial sector,” to “evolve satellite, payload, and
    launch vehicle designs to achieve the most cost-effective and affordable integrated satellite,
    payload, and launch vehicle combination.” 
    Id. Over the
    next several years, the Air Force developed and implemented an acquisition
    strategy for the so-called “evolved” expendable launch vehicle (EELV) program. See App. in
    Supp. of Pls.’ Mot. for Summ. J. (PA) at 598 (Dec. 1, 2017). The acquisition unfolded in several
    phases. See 
    id. at 604–05.
    As relevant here, by 1998, a pre-development demonstration phase
    had been completed, and two contractors—Boeing and Lockheed Martin—had demonstrated the
    viability of their EELV concepts to the Air Force’s satisfaction. See 
    id. at 606.
    2
    The facts set forth below are based on the attachments to the parties’ briefs and the undisputed
    portions of Plaintiffs’ Statement of Undisputed Material Facts in Support of Their Motion for
    Summary Judgment on Counts I and II of Supplemental Complaint (Pls.’ SUMF), ECF No. 118.
    Where a factual dispute exists, it is noted.
    2
    B.      The 1998 Contracts/Agreements
    In 1998, the Air Force settled on a two-pronged approach for the EELV procurement. See
    
    id. at 606–07.
    First, using its “Other Transaction (OT) authority,” the Air Force would enter into
    development agreements with Boeing and Lockheed Martin, under which they would be
    awarded “not more than $500M” to support the “development of a launch capability.”3 
    Id. at 606,
    614–15. Second, under FAR Part 12, the Air Force would award each contractor an initial
    launch services (ILS) contract on a firm fixed-price basis “to satisfy specified [government]
    launch needs from 2002 through 2005.”4 
    Id. at 607.
    At the time, the parties expected that the government would be but “one of many
    customers” to whom the contractors would sell launch services “in the highly competitive,
    lucrative world market.” 
    Id. at 606
    (anticipating that government launches would “constitut[e]
    perhaps 30% of each contractor’s customer base”); see also Pls.’ SUMF ¶¶ 6–11. Thus, in the
    Air Force’s estimation, the $500 million up-front development award, coupled with the fixed-in-
    advance prices for government launches, would “permit[] an equitable and sensible allocation of
    program risk between the Government and the contractor[s].” PA 617. Further, this approach
    would tolerate some “accounting flexibility” in meeting the government’s launch needs, as
    neither the OT agreements nor the ILS contracts would be subject to the government’s CAS. See
    
    id. at 615–17.
    II.      Boeing’s Performance on the Development Agreement and the ILS Contract
    A.      Agreement and Contract Execution
    On October 16, 1998, Boeing and the Air Force executed the development agreement and
    the ILS Contract. Pls.’ SUMF ¶ 13. Boeing’s EELV would be known as the “Delta IV”
    launcher.5 See 
    id. ¶ 8.
    Boeing was awarded nineteen government launches on the ILS contract,
    along with two contingent launches. 
    Id. ¶ 13;
    see also PA 712. At the time, Boeing expected that
    “[c]ommercial markets w[ould] exhibit strong growth” and estimated that it would perform more
    than 390 Delta IV launches by 2020. PA 556, 581; see also Pls.’ SUMF ¶ 8.
    B.      Boeing’s Practice of “Lot Accounting”
    Upon the award of the development agreement and ILS contract, Boeing adopted a so-
    called “lot accounting” method to “account[] for [the] hardware production costs” it would incur
    3
    “When an agency uses its other transactions authority, it need not comply with the procurement
    statutes [or] the FAR,” but it still must “comply with any other statute that applies to contractual
    transactions in general.” John Cibinic, Jr. et al., Formation of Government Contracts 21 (4th ed.
    2011); see also 10 U.S.C. § 2371(a) (granting OT authority to “[t]he Secretary of Defense and
    the Secretary of each military department”).
    4
    FAR Part 12 governs the acquisition of commercial items.
    5
    Lockheed Martin’s EELV launcher, in turn, would be known as the “Atlas V.” See Pls.’ SUMF
    ¶ 2.
    3
    in producing the Delta IV launchers. Pls.’ SUMF ¶ 37. As described below, the purpose of
    adopting this accounting practice was to “average” the costs Boeing incurred in the course of
    making a certain number of launchers across all the missions required to consume those
    launchers. 
    Id. Boeing elected
    to use this average-costing approach because it expected that it would
    incur larger costs towards the start of the ILS contract, when it was standing up its production
    facilities and “learning” how to build the launchers. See PA 1247; PA 1647; DA 897. By
    contrast, it believed that later launchers would be less expensive to build. See PA 1647. Thus, by
    averaging costs across the lot, Boeing expected to smooth out the ebb and flow of the costs it
    would incur. See id.; see also DA 983.
    Boeing’s implementation of this accounting practice proved to be fairly complex. It
    began by identifying eighteen major hardware end-items that would be used, in various
    configurations, in any given Delta IV launcher. See PA 1781 (slide deck presentation describing
    lot accounting); see also 
    id. at 764
    (internal Boeing program memo identifying the 18 end items);
    Pls.’ SUMF ¶ 38. It then defined a “production lot”—known as “Lot 1”—that would consist of a
    certain quantity of each of the eighteen end items.6 Pls.’ SUMF ¶ 37.
    Further, and of particular importance to this case, Boeing incurred common support costs,
    traceable to certain kinds of direct labor, as it produced Lot 1’s major end items. See PA 1647.
    Boeing classified these costs as “program management” and “hardware support” (PM&HS)
    costs.7 See id.; see also Pls.’ SUMF ¶ 38. Boeing included these common costs in Lot 1 and
    treated them as though they were separate end items. See DA 981.
    Under Boeing’s lot accounting practice, the company did not realize the costs incurred to
    produce the Lot 1 end items (including the PM&HS costs) as liabilities on its balance sheet at the
    time they were incurred. See Pls.’ SUMF ¶¶ 41–42. Rather, Boeing classified the costs as an
    asset in the form of work-in-progress (WIP) inventory.8 See 
    id. ¶¶ 41–49.
    6
    The government disputes that Boeing initially defined the lot by reference to quantities of end
    items, and asserts instead that it began by defining the lot in terms of a certain number of
    launchers. See Def.’s Resp. to Pls.’ Statement of Undisputed Material Facts in Supp. of Their
    Mot. for Summ. J. on Counts I & II of Suppl. Compl. (Def.’s SUMF Resp.) at 12–13, ECF No.
    126.
    7
    Program management costs included labor costs for “such activities as Program Office,
    Business Management, Supply, and certain Engineering Labor.” PA 1647; see also DA 982.
    Hardware support costs consisted of costs such as “Quality” and “Support Labor” costs at
    Boeing’s Decatur, AL factory and its Huntington Beach, CA operations center. PA 1647; see
    also DA 982.
    8
    Thus, as an accounting matter, when it incurred costs, Boeing recorded the conversion of one
    asset (i.e., cash on hand) to another asset (inventory). Because of this, the parties and the Court
    occasionally refer to these costs as “inventoried” costs or expenses.
    4
    Later, Boeing realized the costs as liabilities on a “mission-by-mission basis” when
    missions were launched. See Pls.’ SUMF ¶ 50. Specifically, for each mission, it would tally the
    proportional costs associated with the end items used in that mission’s launch vehicle (including
    a proportional measure of the PM&HS costs); add in other costs associated with that mission to
    arrive at a “cost of sale”; and match the cost of the sale (a liability) against the revenue received
    for the mission.9 Pls.’ SUMF ¶¶ 50–54; see also PA 764–65 (draft program review memorandum
    describing proportional distribution of costs).
    C.      Boeing Faces Challenges As the Commercial Launch Market Fails to Take
    Off
    In the early 2000s, the robust and lucrative commercial launch market of the parties’
    projections failed to materialize. Pls.’ SUMF ¶ 15 (“[I]t . . . became clear that there were few
    commercial customers for EELV launch services.”); see also PA 770 (market analysis from
    September 2002 describing the market as “soft”). As a result, by June 2003, Boeing essentially
    pulled the Delta IV off the commercial market, and made a downward adjustment to the number
    of Delta IV launches it believed would take place by 2020. Pls.’ SUMF ¶ 17; see also PA 862–64
    (decreasing projected commercial launches through 2020 from 162 to 25, and overall launches
    from 369 to 201).
    As a result of this downward adjustment, the period of time required to consume Lot 1’s
    end items now stretched well beyond Boeing’s initial projections. See PA 1001–02 (2004
    analysis projecting that Lot 1’s end items would not be consumed until 2010, nearly a decade
    later than first expected). Further, because of the dearth of commercial opportunities, most of Lot
    1’s end items would be devoted to government contracts—for which Boeing had already fixed
    prices under the ILS contract.10 See 
    id. at 786–88.
    9
    The Court notes that because launches would begin (and Boeing would thus realize costs)
    before Boeing had incurred all the costs to complete the lot, Boeing had to compute “average”
    costs for launches before it knew (1) the actual total costs to complete the lot, and (2) the total
    number of missions that would be required to use all of the lot’s end items. To do so, it relied on
    an estimated cost at completion (EAC), which it divided by the projected number of missions to
    calculate average costs. See Pls.’ SUMF ¶ 54; see also PA 1646–48 (describing how the
    “average cost to be assigned . . . to individual units” depended on “the total cost estimate[] to
    complete the units in the lot,” and how the proportion of the PM&HS costs assigned to a mission
    depended on the number of projected missions); DA 898, 977. Boeing asserts that, as it incurred
    additional costs after its early launches, it “adjusted the cost of sales charged for launched
    missions on a quarterly basis to reflect updated EACs for those missions.” Pls.’ SUMF ¶ 54.
    10
    Thus, had Boeing booked two commercial launches for every government launch, only about
    one-third of Lot 1’s end items would have been used for government launches. But with few
    commercial launches on the horizon, nearly all of Lot 1’s end items would be used in
    government launches. See PA 868–70 (describing this effect and observing that Boeing expected
    that it would have to find a way to adjust the prices of its government missions upward).
    5
    These changes, however, had no effect on the cost to complete the items in Lot 1; and, in
    fact, Lot 1’s EAC drifted upward over time, contravening (at least in part) Boeing’s assumption
    that the later-in-time end items would be cheaper to produce due to efficiencies from learning.
    See, e.g., 
    id. at 773–76
    (noting quarterly EAC growth of $285.1 million from 2002 Q2 to 2002
    Q3); see also 
    id. at 1752.
    This combination of circumstances led Boeing to record significant
    losses on its “definitized” contracts in the second quarter of 2003.11 
    Id. at 775–76,
    786–89; see
    also Pls.’ SUMF ¶¶ 19–20.
    Then, in March 2003, the Air Force informed Boeing of an investigation into whether it
    had committed a Program Integrity Act (PIA) violation in the course of bidding on the ILS
    contract in 1998. DA 121–23; see also PA 1001. As a result of the investigation, the Air Force
    ultimately transferred seven ILS contract launches away from Boeing and suspended Boeing
    from participation in further launch procurements for a time.12 See DA 123–24; see also
    PA 1001, 1120. Thus, by mid-2004, Boeing had again adjusted its manifest downward, to 117
    launches by 2020. See PA 916–18; 
    id. at 1001–02.
    III.   The Air Force Decides to Restructure the EELV Contracts
    A.      The 2005 Update to U.S. Space Transportation Policy
    In a January 6, 2005 update to the nation’s space transportation policy, the president
    acknowledged that the “significant downturn in the market for commercial launch services ha[d]
    undermined . . . the ability of industry to recoup its significant investment in current launch
    systems.” 
    Id. at 1077.
    Thus, “[t]o assure access to space” going forward, the government would
    have to “provide sufficient and stable funding for [the] acquisition of U.S. space transportation
    capabilities.” 
    Id. B. The
    Air Force’s Revised Acquisition Policy
    On March 10, 2005, the Air Force distributed a revised EELV acquisition strategy
    intended to implement the updated space transportation policy. 
    Id. at 1114–27.
    The Air Force’s
    stated goal was to achieve “assured access to space” in a manner that “allows the contractors
    viability, yet holds them accountable for past business decisions.” 
    Id. at 1117.
    To achieve these aims, the Air Force resolved to award “two . . . contracts for each
    [launch] provider under FAR Part 15.” 
    Id. at 1124.
    The first would be “a cost reimbursable-type
    award fee contract for launch capability.” 
    Id. The second
    would be a “firm fixed price contract
    with a[] M[ission] S[uccess] I[ncentive] for the launch services.” 
    Id. 11 When
    it recorded these losses, Boeing defined a “definitized” contract as “a signed and legally
    binding contract.” PA 786. Further, it “consider[ed] priced options that [we]re probable of being
    exercised to be definitized contracts,” and stated that “Lot #1 consist[ed] of 36 launches[,] of
    which 24 [we]re definitized.” 
    Id. at 786,
    788.
    12
    The Air Force lifted the suspension on March 4, 2005. PA 1120. It is unclear whether Boeing
    booked any additional losses as a result of this penalty.
    6
    Under this approach, the launch capability contract would provide the contractors with an
    assured stream of funding to devote to ongoing expenses such as “[l]aunch infrastructure
    elements”; “prime and supplier critical skills retentions”; “factory [and] engineering support”;
    and “program management.” See 
    id. at 1124–25.
    Meanwhile, under the launch services contract,
    the government would pay separately for specific mission needs, including “launch hardware
    (core vehicle and upper stage)” and “mission hardware (payload fairing, payload adapter/attach
    fitting, mission unique hardware build).” See 
    id. at 1124.
    Importantly, under this contract structure, when Boeing incurred new costs of the type it
    had characterized as PM&HS costs under the ILS contract, such costs would be reimbursable
    under the launch capability contract, not the launch services contract. See Pls.’ SUMF ¶ 60.
    Further, in the acquisition policy, the Air Force announced that “[l]osses incurred under
    the 1998 OTA and ILS contracts . . . w[ould] not be recoverable under” the restructured
    contracts. PA 1125; see also 
    id. (government intended
    to “maintain the contractors’ loss position
    on previous awards”). And because the new contracts would be governed by FAR Part 15, the
    government would also gain “significantly more insight/oversight into the contractors’
    management, technical, cost[,] and schedule performance,” not least because the government’s
    CAS would apply. See 
    id. at 1121;
    see also 
    id. at 2019.
    In particular, the Air Force specified that
    it would “review . . . [the] contractors’ investments and costs . . . prior to contract award” and
    make a “determination of what contract costs can be recovered in compliance with the OTA and
    ILS contracts and current CAS.” 
    Id. at 1127.
    IV.    Boeing’s Proposals and DCAA’s First Audits
    A.      Initial Proposals and Definition of DSC Costs
    Pursuant to the revised acquisition policy, the Air Force issued RFPs for the new EELV
    launch capability (ELC) and EELV launch services (ELS) contracts in April 2005. Pls.’ SUMF
    ¶ 66. Boeing submitted its initial proposals on June 20, 2005. 
    Id. ¶ 67.
    In preparing its proposals, Boeing realized that after the restructuring, the types of costs it
    had characterized as PM&HS costs would fall under the rubric of the ELC contract, not the ELS
    contract. See 
    id. ¶ 60;
    see also PA 1649; DA 982. Boeing’s inventoried costs, however, included
    PM&HS costs that it had already incurred and associated with anticipated future missions. See
    Pls.’ SUMF ¶ 61; see also PA 2021–22. The parties refer to these costs as “deferred support
    costs,” or “DSC.” Pls.’ SUMF ¶ 62. Boeing had expected to recover these costs (or realize losses
    on them) on its launch services contracts, and those launches would now take place during the
    period covered by the ELC contract. See Pls.’ SUMF ¶ 61; see also PA 2021–22.
    To ensure that it could recover the inventoried DSC costs on the ELC contract, Boeing
    “sought an advance agreement providing that it would continue to use lot accounting, except for
    certain costs that had been accumulated in inventory [i.e., the DSC costs], which Boeing
    proposed to recover by charging directly to final cost objectives of the ELC contract.”13 
    Id. ¶ 67
    13
    “Advance agreements may be entered into between the government and a contractor prior to
    the incurrence of the costs involved in a contract and serve to express the parties’ understanding
    7
    (quotation and alteration omitted); see also PA 1247–48, 1258–59 (bid excerpts detailing
    proposed advance agreements).14
    B.      DCAA’s First Pre-Negotiation Audits
    After Boeing submitted its proposals, the parties began a long and complicated
    negotiation process. See Pls.’ SUMF ¶¶ 67–119 (covering the period from June 20, 2005 through
    November 16, 2006). These negotiations featured successive audits of Boeing’s proposals
    conducted by the Defense Contract Audit Agency (DCAA). See 
    id. ¶¶ 68–70,
    77–78, 85–86.
    Thus, in July and August 2005, DCAA first determined that Boeing’s initial proposals for
    the ELC and ELS contracts were “inadequate as a basis for negotiation of a fair and reasonable
    contract price” for a number of reasons, including “potential noncompliances with CAS 406.”15
    See PA 1260–96 (ELC proposal audit report, dated July 29, 2005); 
    id. at 1297–1327
    (ELS
    proposal audit report, dated August 5, 2005). With respect to the ELC contract, DCAA noted that
    Boeing’s proposal “included approximately $333 million of previously incurred [PM&HS]
    costs,” which Boeing “propose[d] to ‘roll-forward’ to the ELC contract” in a manner that might
    not comply with CAS 406. See 
    id. at 1262.
    As to the ELS contract, DCAA observed that in
    implementing its lot accounting practice “to arrive at total Lot 1 hardware costs,” Boeing
    proposed to sum the “costs incurred . . . since 1997” with “an [estimate] of [the] costs required
    for completion of [the Lot] . . . in approximately 2011.” 
    Id. at 1300.
    According to DCAA, this
    practice—i.e., “averaging significant costs over an extended period of time”—was “potentially
    noncompliant with . . . CAS 406[].” 
    Id. In the
    wake of DCAA’s conclusions, the Air Force considered obtaining CAS waivers for
    the ELC and ELS contracts, but never did so. See Pls.’ SUMF ¶¶ 72–74; PA 1393, 1401.
    and avoid possible subsequent disputes or disallowances.” Raytheon Co. v. United States, 
    105 Fed. Cl. 236
    , 243 n.17 (2012) (citing FAR 31.109), aff’d, 
    747 F.3d 1341
    (Fed. Cir. 2014). In
    particular, the FAR encourages parties to “seek advance agreement on the treatment of special or
    unusual costs.” FAR 31.109(a). Ideally, however, such agreements “should be negotiated before
    incurrence of the costs involved.” 
    Id. § 31.109(b).
    Further, contracting officers are “not
    authorized . . . to agree to a treatment of costs inconsistent with this part.” 
    Id. § 31.109(c).
    14
    According to Boeing, when it submitted its initial proposals, it also expected to “recover
    through the firm fixed prices for missions awarded under the [new] ELS contract” any “hardware
    production costs it had incurred prior to the restructure and which [it] had . . . inventoried” using
    lot accounting. See Pls.’ SUMF ¶¶ 64–65; see also PA 1647–48; DA 982. The issues related to
    these deferred production costs are discussed in more detail below.
    15
    For convenience, the Court uses “CAS” to refer to the different provisions found in FAR Part
    9904, so that “CAS 406” is the equivalent of “FAR 9904.406.” Further, as discussed in more
    detail below, CAS 406 concerns “the selection of the time periods to be used as cost accounting
    periods for contract cost estimating, accumulating, and reporting.” See CAS 406–20.
    8
    V.     ELC Contract Negotiations and Execution
    A.      Revised ELC Proposal and DCAA’s Second Pre-Negotiation Audit
    Boeing eventually submitted a revised proposal for the ELC contract on January 17,
    2006. Pls.’ SUMF ¶ 75. In it, Boeing proposed that the government make payments to it each
    year in amounts derived from Boeing’s inventoried PM&HS costs, such that the total payments
    after six years would equal an agreed-upon amount for those costs. See PA 1596.
    Several months later, on May 8, 2006, DCAA issued an audit report regarding the revised
    proposal. See PA 1593–1635. Unlike the prior reports, this report omitted any reference to
    potential CAS violations presented by the lot accounting or Boeing’s deferred costs.16 See 
    id. Further, DCAA
    determined that the revised proposal was “inadequate in part for negotiation of a
    fair and reasonable price,” rather than wholly inadequate.17 See 
    id. at 1594
    (emphasis added).
    B.      Memorandum of Understanding
    Based on DCAA’s conclusion that the revised proposal was merely “inadequate in part,”
    
    id. at 1594
    , the parties moved forward with negotiations. Soon afterward, on June 19, 2006, the
    parties executed a memorandum of understanding (MOU) describing “the conditions and
    understandings pursuant to which [they] h[ad] agreed, in principle, to enter into” the ELC
    contract. 
    Id. at 1636;
    see also Pls.’ SUMF ¶ 79. In particular, they agreed that the contract would
    include a “fixed price CLIN” devoted to paying deferred support costs, the total value of which
    “w[ould] be calculated over an estimated 8 year period.” PA 1638. Further, the parties provided
    that the execution of the ELC contract “may be contingent upon the execution and approval” of
    advance agreements concerning lot accounting and the DSC costs. Pls.’ SUMF ¶ 81 (quotation
    omitted).
    16
    The government states that it “disputes any suggestion that the May 8, 2006 Audit Report
    concluded that Boeing’s proposed recovery of its inventoried PM&HS costs on the ELC contract
    was in fact compliant with the CAS” because the report did not affirmatively opine that the
    proposal was CAS-compliant. See Def.’s SUMF Resp. at 27–28.
    17
    Although it did not identify any CAS noncompliance in the proposal, DCAA observed in an
    extended discussion that “the unabsorbed PM&HS cost pool contain[ed] costs associated with a
    significant number of launches (primarily commercial) that were anticipated in 1998” but that
    never occurred. PA 1596. DCAA expressed its “belie[f] that some of these costs may not be
    allocable to this and future EELV contracts in accordance with [the Air Force’s] Revised
    Acquisition Strategy,” which, as noted, “stat[ed] that losses incurred under the 1998 OTA and
    ILS contracts . . . w[ould] not be recoverable under [the restructured contracts].” 
    Id. (quotation omitted).
    Nevertheless, DCAA was of the view that “whether or not payment of these costs
    w[ould] further the objective to maintain Assured Access to Space” was “a procurement
    decision.” 
    Id. at 1597.
    9
    C.      Negotiating and Finalizing the Lot Accounting and DSC Advance
    Agreements
    1.      Drafts and DCAA’s Audits
    Soon thereafter, the parties exchanged drafts of the DSC and Lot Accounting advance
    agreements that Boeing sought. See 
    id. ¶¶ 83–84.
    By this point, personnel from the Defense
    Contract Management Agency (DCMA) had become deeply involved in the negotiations, and, in
    September 2006, DCMA requested audit service from DCAA regarding the draft advance
    agreements. See PA 1745–52. In particular, DCMA inquired about whether the advance
    agreements complied with CAS and the applicable provisions of the FAR. 
    Id. at 1747,
    1751.
    With respect to the deferred support costs, DCAA referred DCMA to its previous audit,
    stating that the “audit did not disclose any CAS or FAR noncompliances.” 
    Id. at 1747.
    It
    observed, however, that (as noted above) it had qualified its opinion with regard to the interplay
    of DSC and the Air Force’s acquisition strategy, and stated that this qualification “could affect
    FAR compliance.” See 
    id. And as
    to lot accounting, DCAA stated that it had “not identif[ied]
    any FAR [or] CAS noncompliances.”18 
    Id. at 1752.
    2.      Revisions Made By the Contract Management Board of Review
    In November 2006, the government convened a contract management board of review
    (Review Board) to consider whether executing the proposed advance agreements would be in the
    government’s best interests.19 See Pls.’ SUMF ¶¶ 88–91. According to minutes summarizing the
    meeting, the Review Board observed that “concern had been expressed that” if “costs incurred
    and anticipated under the prior . . . contract” were “transitioned” to the restructured contracts, the
    government would in effect be “subsidizing Boeing for past losses.” PA 2401. According to the
    Review Board, however, “the supporting documentation for the[] [advance] agreements shows
    that the Government affirmatively determines there not to be a subsidy.” 
    Id. With respect
    to the Lot Accounting advance agreement, the Review Board noted that
    Boeing “[r]ecognized that the [contracting officer] could not award a contract with noncompliant
    18
    DCAA did observe, however, that the continued use of lot costing could “put[] the government
    at increased risk” of paying higher prices for launches because it could lead to the inclusion of
    “escalated costs well into the future when pricing current requirements.” PA 1752. The cause of
    this escalation was the steep rise of Boeing’s projected corporate labor rates over time and the
    long duration of the lot; put together, these factors meant that the further out the final Lot 1
    launch date slipped, the greater the “average” labor rate included when pricing a launch. See 
    id. (noting that
    that “a $30 per hour 1996 labor rate” would grow to “a $61 per hour 2011 labor rate”
    and then up to a “$99 per hour [rate] for 2021”).
    19
    While the Board itself consisted of four voting members, the meeting was attended by
    numerous representatives from multiple stakeholders, including DCAA, the Air Force, the Air
    Force’s general counsel’s office, and the National Reconnaissance Office. See Pls.’ SUMF
    ¶¶ 89–90; Def.’s SUMF Resp. at 31–32.
    10
    accounting practices.” 
    Id. at 2402.
    It also “confirmed” that DCAA had concluded (in its second
    pre-negotiation audit) that lot accounting did not violate CAS. 
    Id. The Review
    Board itself, however, “declined to give any express approval of [the]
    practice.” 
    Id. at 2403.
    It therefore revised the proposed agreement to state that “as of the date [of
    the advance agreement’s execution], the undersigned [contracting officer] has found Lot
    Accounting a compliant practice under the [CAS].” 
    Id. Further, the
    revised agreement stated that
    “[t]his determination is not intended to and does not prevent the revocation, withdrawal, or
    reconsideration of this determination if subsequent facts indicate that some aspect of this
    disclosed practice is noncompliant with CAS or FAR.” 
    Id. As for
    the DSC advance agreement, the Review Board observed that “to some, [the]
    PM&HS [costs] appeared to consist of failed business costs being carried forward.” 
    Id. But “[a]fter
    discussing” the issue “at length,” the Board determined “under the lot accounting
    concept, Boeing was not attempting to transfer period costs . . . to a later accounting period” via
    the DSC advance agreement; instead, it was “attempting to recover legitimate costs within the
    scope of Government accounting and contract rules.” 
    Id. at 2404.
    The Review Board then settled
    on the following language for the DSC advance agreement:
    [T]he parties agree that the amount of $271,152,672 represents costs
    for program management and hardware support under the Delta 4
    program that were incurred and placed in an inventory account prior
    to June 1, 2006, but were neither allocable to nor payable under
    obligations on contracts entered into or performed prior to that date.
    The Air Force has discussed the potential to compensate the
    contractor for such unreimbursed expenses on a separate line item
    on future contracts, and has agreed on a method by which the
    contractor may be paid for 1/8 share of such $271,152,672 amount
    as a fixed-price contract line item in each year of future contracts, if
    awarded. Any such line item related to these expenses is separate
    from recovery of costs under cost-reimbursement provisions of such
    contracts.
    
    Id. Having made
    these revisions, the Review Board ultimately determined that the advance
    agreements were in the government’s best interests. 
    Id. at 2406.
    D.      ELC Contract Execution
    Boeing and the government executed the DSC advance agreement on November 8, 2006.
    Pls.’ SUMF ¶ 104. The following week, on November 13, 2006, the parties executed the Lot
    Accounting advance agreement. 
    Id. ¶ 114.
    The executed agreements contained the operative
    language described above. See 
    id. ¶¶ 104,
    114.
    Three days later, on November 16, 2006, the parties executed the ELC contract. 
    Id. ¶ 120.
    The ELC contract expressly incorporated the DSC and Lot Accounting advance agreements and
    stated that “[e]ach Advance Agreement [wa]s an integral part of this contract that was a
    11
    substantial factor in determining Contract value.”20 
    Id. ¶ 121
    (quoting PA 2384). The contract
    also stated that for fiscal years 2006 and 2007, Boeing would “bill deferred support on an annual
    basis under CLINs 1501 and 1502.” 
    Id. ¶ 122
    (quoting PA 2391). The total amount to be paid in
    those two years equaled $67,788,168.21 
    Id. ¶ 123.
    VI.    The Formation of ULA and Novation of the ELC Contract
    In the meantime, some months before executing the ELC contract, on May 2, 2005,
    Boeing entered into a joint venture agreement with Lockheed Martin to form United Launch
    Alliance (ULA), of which ULS is a subsidiary. See 
    id. ¶¶ 34,
    132. The JV agreement became
    effective December 1, 2006. See 
    id. As discussed
    below, throughout 2007, the parties turned their attention to negotiating the
    ELS contract, which they executed on January 24, 2008. See 
    id. ¶ 145.
    Within a few months, by
    mid-April 2008, Boeing’s EELV contracts (including the legacy ILS contract, the ELC contract,
    and the ELS contract) had been novated to ULS.22 
    Id. ¶¶ 132–135.
    Like the original ELC
    contract, the novated ELC contract incorporated the DSC and Lot Accounting advance
    agreements. 
    Id. ¶ 135.
    VII.   ELS Contract Negotiations and the Formation
    A.      ULA Abandons Lot Accounting Retroactive to December 1, 2006
    After it began operations in late 2006, ULA determined that it needed to adopt “like
    accounting practices” for the “efforts [it] performed on the Atlas and Delta IV programs”
    because ULA was a new company and those programs were “common in both business nature
    and scope.” PA 2647; see also Pls.’ SUMF ¶ 141; DA 1052 (letter to DCMA from James Hardin,
    Jr., ULA’s Vice President and Controller, observing that “[i]n accordance with GAAP, ULA
    must . . . [h]ave the same business and accounting practices for both Atlas and Delta”). By July
    2007, ULA had elected to use Lockheed Martin’s “heritage practice” of “Annual Production
    Cycle (APC)” accounting, which Lockheed had used for the Atlas program, rather than Boeing’s
    lot accounting practice or an entirely new practice. DA 1052; see also Pls.’ SUMF ¶ 141. In
    summarizing this decision, Mr. Hardin noted his belief that as a new company, ULA could not
    adopt lot accounting because “the Lot Accounting inventory process . . . does not conform to
    GAAP.” DA 1052; see also 
    id. at 1109
    (letter to DCAA from Mr. Hardin concluding that ULA
    “could not adopt the heritage Boeing practice . . . of lot cost (program method) accounting”).
    20
    The contract further stated that the Lot Accounting advance agreement would “also be
    incorporated into the interdependent EELV Launch Services Contract, if awarded.” Pls.’ SUMF
    ¶ 121 (quoting PA 2384).
    21
    Later contract modifications added CLINs 1503 (payments for fiscal year 2008) and 1504
    (payments for fiscal year 2009). Pls.’ SUMF ¶ 128.
    22
    The parties dispute the precise timing of the novation, as well as the exact nature of the
    program assets that Boeing transferred to the joint venture. See Def.’s SUMF Resp. at 47–48.
    12
    ULA made this change retroactive to December 1, 2006, the date it started independent
    operations. See DA 1053; Pls.’ SUMF ¶ 141.
    B.      Negotiations and Formation of the DPC Advance Agreement and the ELS
    Contract
    The switch to APC accounting caused a complication with respect to certain direct
    hardware production costs—known as deferred production costs (DPC)—that Boeing had
    incurred and inventoried before December 1, 2006.23 See Pls.’ SUMF ¶ 142; PA 2621. Under
    APC accounting, “the costs incurred to produce particular items of hardware” would be allocated
    entirely “to those units in production during the year the cost was incurred.” Pls.’ SUMF ¶ 142.
    But, as with the DSC costs, when Boeing had incurred such hardware production costs prior to
    2006, it had inventoried them using lot accounting and associated a portion with units to be
    produced/sold in future years under anticipated launch contracts, rather than to units in
    production during the years the costs were incurred. See PA 2621; see also DA 1095 (describing
    these costs as a “wedge” of previously incurred costs). Switching to APC accounting could
    therefore have the effect of “isolat[ing]” these inventoried hardware production costs from
    allocation to future missions. See PA 2621.
    Throughout the latter half of 2007, the parties worked to negotiate an acceptable advance
    agreement regarding the treatment of the DPC, while simultaneously negotiating the ELS
    contract. See Pls.’ SUMF ¶¶ 143–44. On January 24, 2008, before signing an advance
    agreement, Boeing and the Air Force executed the ELS contract. See 
    id. ¶ 145.
    Two months later, on March 25, 2008, the parties executed the DPC advance agreement.
    
    Id. ¶ 149;
    see also PA 2627–28. Under the agreement, DCAA was to “audit the amount, the
    allowability[,] and the allocability of the proposed costs.” PA 2627. “Following” the audit, the
    parties “agree[d] to negotiate a fair and reasonable value representing the total Delta IV
    [DPC] . . . that were incurred and placed in an inventory account prior to December 1, 2006, but
    were neither allocable nor payable under obligations on contracts entered into or performed prior
    to that date.” 
    Id. Further, the
    y agreed to “allocate the negotiated . . . costs to future Delta IV
    launch service missions . . . until the total negotiated value has been liquidated.” 
    Id. According to
    the agreement, the costs would be “in addition to whatever costs are allocable to, and are
    allowable costs under such future missions pursuant to the [APC] costing methodology.” 
    Id. VIII. The
    Genesis of the Instant Dispute
    A.      DSC
    1.      The 2008 GAO Report and Subsequent IG Report
    In July 2008, the Government Accountability Office (GAO) issued a report criticizing
    DCAA’s handling of several audits, including its 2006 audit of Boeing’s revised ELC contract
    proposal. See 
    id. at 2769–86.
    In particular, GAO concluded that its investigation had
    23
    These costs included costs for “production labor, associated burden[,] and appropriate other
    direct cost[s].” PA 2627.
    13
    “substantiated concerns” that had been raised about “(1) buying command and contractor
    pressure for a favorable audit opinion and (2) an unsupported change in the draft audit opinion
    that was directed by DCAA Western Regional officials.” 
    Id. at 2780;
    see also 
    id. at 2781
    (stating
    that DCAA “auditors told [GAO] that they were instructed by the [Regional Audit Manager] not
    to document CAS compliance issues in the[ir] workpapers”).
    Two months later, in September 2008, the Senate Committee on Homeland Security and
    Governmental Affairs held a hearing on the issues raised in the GAO report, at which at least one
    DCAA auditor gave testimony. See Pls.’ SUMF ¶¶ 168–72. Further, at the request of the Senate
    Armed Services Committee, the DoD’s Inspector General (IG) then conducted a follow-up
    investigation. See 
    id. ¶¶ 166–67,
    174; see also PA 3139–83 (final IG report). In preliminary
    findings circulated on October 20, 2008, the IG “recommend[ed] that the Air Force take
    immediate action to suspend potentially improper payments under the EELV program
    and . . . reassess the propriety of [the] existing advance agreements.” PA 2887. The IG later
    issued a final report on August 31, 2009, in which it described the 2006 audit as “flawed”;
    reiterated the recommendations in its preliminary findings; and further recommended that the Air
    Force “cease negotiations” on the DPC costs. 
    Id. at 3142,
    3146.
    2.      DCAA’s 2010 Re-Audit
    In response to the GAO report, DCAA opened a new audit of the inclusion of the DSC
    costs in Boeing’s ELC contract. See 
    id. at 2799;
    see also Pls.’ SUMF ¶ 164. It completed the
    audit and issued a final report on July 23, 2010. Pls.’ SUMF ¶ 205; see also PA 3431–82. In the
    report, DCAA concluded that Boeing was in non-compliance with CAS 406 (concerning cost
    accounting periods) and CAS 405 (governing accounting for unallowable costs). PA 3432.
    According to DCAA, “[t]he CAS 406 noncompliance was caused by Boeing’s use of the lot
    accounting inconsistent with the CAS requirements.” 
    Id. The CAS
    405 noncompliance,
    meanwhile, resulted from Boeing’s inclusion in the proposal of “deferred support costs [that]
    represent[ed] losses that are expressly unallowable under the provisions of FAR 31.205–23,
    Losses on Other Contracts.” 
    Id. DCAA also
    observed that “[t]o date, the contractor has billed the Government for
    $101,435,379 of the deferred support costs and has received $72,198,875 of the billed amount.”
    
    Id. It also
    noted that its “examination d[id] not provide [a] legal determination on [Boeing’s]
    compliance with the specified requirements.” 
    Id. at 3433.
    3.      The Administrative Contracting Officer’s Non-Compliance Decision
    Nearly a year later, on June 16, 2011, the responsible administrative contracting officer
    issued a final decision finding that “Boeing’s Lot Accounting practice is noncompliant with CAS
    406 . . . and CAS 405.” 
    Id. at 3836.
    According to the CO, “the increased cost in the
    aggregate . . . is $271,152,672[,] of which $72,198,875 has been paid.” 
    Id. The CO
    therefore
    14
    “assert[ed] a . . . claim for $72,198,875 in principal and $17,036,292 in interest . . . for a total
    claim of $89,235,167.”24 
    Id. B. DPC
    Following the execution of the DPC advance agreement in March 2008, Boeing
    submitted a proposal that purported to “serve[] to both identify the total value of the recoverable
    deferred production cost[s] and demonstrate the methodology utilized to appropriately calculate
    this value.” 
    Id. at 2629;
    see also Pls.’ SUMF ¶ 229. The proposal “estimated $114.1 million of
    DPC within the scope of the ELS Contract.” Pls.’ SUMF ¶ 229; see also 
    id. ¶¶ 230–32
    (describing the methodology Boeing used to derive this figure). Boeing also noted that “[t]he
    proposal . . . [wa]s subject to audit by [DCAA] and final negotiation with [the Air Force].” PA
    2629.
    Although DCAA circulated a draft audit of the proposal in November 2008, see Pls.’
    SUMF ¶ 235, it did not issue a final audit report until May 3, 2011, 
    id. ¶ 244;
    see also PA 3591–
    3616. In the report, DCAA “questioned the proposed costs in total” and stated that it “d[id] not
    believe the proposal [was] an acceptable basis for negotiating a fair and reasonable deferred
    production cost amount.” PA 3593. It also stated that Boeing would be in non-compliance with
    CAS 406 and CAS 405 if it “propose[d] . . . and subsequently bill[ed] . . . the DPC on CAS
    covered contracts,” and noted that it had “initiated a separate assignment” to evaluate such non-
    compliances. 
    Id. at 3594.
    At the close of that separate assignment, on October 20, 2011, DCAA issued another
    audit report. See Pls.’ SUMF ¶ 245; see also PA 3918–46. In that report, DCAA concluded that
    Boeing was further “in noncompliance with” CAS 406 and CAS 405 based on its inclusion of
    estimated amounts for DPC in certain proposals it had submitted for launches under the ELS
    contract. PA 3921. DCAA also noted its belief that the DPC advance agreement was “not valid”
    because it did not “accord[] with . . . FAR 31.109(c) which states[] [that] ‘[t]he contracting
    officer is not authorized . . . to agree to a treatment of costs inconsistent with this part.’” 
    Id. at 3931
    (quoting FAR 31.109(c)).
    Based on these determinations, DCAA recommended that the Air Force “rescind the
    [DPC] advance agreement”; “[e]nsure that no payments are made to the contractor for
    unallowable deferred production costs”; and “modify all ELS contracts . . . to remove references
    to the DPC.” 
    Id. About two
    months later, on December 12, 2011, a divisional administrative contracting
    officer sent Boeing a notice of potential noncompliance with CAS 406 and CAS 405. Pls.’
    SUMF ¶ 253; see also PA 3963–64. Boeing responded to the notice on February 10, 2012. Pls.’
    SUMF ¶ 254. Boeing filed this lawsuit before the CO issued a final finding. See 
    id. 24 Boeing
    paid over the requested amount by July 5, 2011. See Pls.’ SUMF ¶ 228.
    15
    IX.    Boeing’s Claim for Recovery of DSC and DPC
    On November 10, 2011, Boeing submitted a certified claim to the CO “seeking relief
    with respect to both DSC and DPC.” 
    Id. ¶ 284.
    In terms of DSC, Boeing sought both the return
    of the $89,235,167 it had paid to the government following the June 16, 2011 final decision, as
    well as $33,894,084 that Boeing claimed was due for the 2011 fiscal year. See 
    id. ¶ 285.
    As to
    DPC, Boeing requested $40,956,790 “for those missions that had been ordered and definitized by
    the Government as of the date the claim was submitted” and $19,158,582 “for those missions
    that, when they were ordered, were the subject of ‘not-to-exceed’ prices that did not include
    DPC, but that had not yet been definitized as of the date the claim was submitted.” 
    Id. ¶ 286.
    The Air Force denied the claim on May 15, 2012. 
    Id. ¶ 288;
    see also PA 4216–24 (DPC);
    PA 4225–32 (DSC). First, regarding DSC, the CO observed that the government had previously
    determined that “Boeing’s Lot Accounting was not compliant with CAS 406 and 405, and that
    DSC were not allowable.” PA 4230. Further, according to the CO, the inclusion of DSC CLINs
    in the ELC contract “did not create an irrevocable binding contractual obligation to recognize
    DSC as an allowable cost, or pay unallowable DSC.” Id.; see also

    (observing that a
    CO’s “authority d[oes] not extend to making determinations contrary to law,” and that “the
    procurement authority of the [relevant COs] was expressly limited by the EELV Revised
    Acquisition Strategy and FAR 31.205–23, which prohibit[s] the recovery of losses on other
    contracts”).
    Second, as to DPC, the CO determined that neither the execution of the DPC advance

    contractual obligation to recognize the allowability of DPC costs.”

    He also observed
    that the DPC advance agreement in fact “state[d] that any further negotiation of DPC is subject
    to full audit.” 
    Id. Further, as
    with DSC, he noted that “[t]o the extent DPC may represent losses

    to law.” 
    Id. X. This
    Action
    Boeing filed suit here on June 14, 2012. ECF No. 1. It later filed the operative
    supplemental complaint on August 14, 2015. ECF No. 67-1.
    In Count I of its complaint, Boeing contends that “[n]othing in CAS or federal law or
    regulations precludes the recovery of DSC” under the ELC contract, and therefore that the
    government has breached that contract by demanding repayment of the $72,198,875 that it paid
    Boeing under CLINs 1501, 1502, and 1503, and refusing to make any further DSC payments.
    See Suppl. Compl. ¶¶ 202–03.
    Further, in Count II, Boeing asserts that the government has breached the ELS contract
    by failing to negotiate a reasonable value for the DPC costs and allocate it among missions under
    the ELS contract, as it allegedly promised to do. 
    Id. ¶ 209.
    As a result, Boeing claims it has
    suffered damages “in the amount of $106,095,968, which is the total amount included in
    16
    reservation-of-rights clauses with respect to DPC for the post-ILS contract missions that have
    been ordered and definitized by the Air Force, plus any additional reasonable rate of return due
    on the unpaid DPC amounts.” 
    Id. ¶ 217.
    The government filed an answer and counterclaim on October 9, 2015. ECF No. 72. As
    relevant here, the government stated as an affirmative defense that Boeing’s claims were “barred
    by illegality as the procurement contracting officer had no authority to agree to pay DSC or
    DPC, and any agreement to pay DPC or DSC violates Cost Accounting Standards 406 and 405
    and the Federal Acquisition Regulations.” Def.’s Answer to Pls.’ Suppl. Compl. & Countercl.
    ¶ 265.
    Given the case’s factual complexity and the parties’ interest in exploring settlement, the
    discovery period lasted several years. See, e.g., ECF Nos. 48, 56, 85. In March 2016, the parties
    informed the Court of their intention to mediate the case, ECF No. 96, and, at their request, the
    Court stayed the case in June 2016, ECF No. 103. But the mediation was unsuccessful, and the
    Court lifted the stay on March 31, 2017. ECF No. 112.
    Thereafter, on November 11, 2017, Boeing filed a motion for summary judgment as to
    Counts I and II of its complaint. ECF No. 116. The government filed its response in opposition
    on February 23, 2018. ECF No. 125. It did not rely on CAS 405 as a ground for its affirmative
    defense in its brief. See 
    id. The Court
    heard oral argument on June 21, 2018. See ECF No. 131.
    DISCUSSION
    I.      Jurisdiction
    The Tucker Act grants the United States Court of Federal Claims jurisdiction to “render
    judgment upon any claim against the United States founded either upon the Constitution, or any
    Act of Congress or any regulation of an executive department, or upon any express or implied
    contract with the United States, or for liquidated or unliquidated damages in cases not sounding
    in tort.” 28 U.S.C. § 1491(a)(1) (2012). Subsection (a)(2) of the Tucker Act further grants the
    Court of Federal Claims “jurisdiction to render judgment upon any claim by or against, or
    dispute with, a contractor arising under section 7104(b)(1) of title 41”—that is, the Contract
    Disputes Act (CDA)—“including a dispute concerning termination of a contract, rights in
    tangible or intangible property, compliance with cost accounting standards, and other
    nonmonetary disputes on which a decision of the contracting officer has been issued under
    section 6 of that Act.” 
    Id. § 1491(a)(2).
    The CDA, in turn, applies to, among other things, an “express or implied
    contract . . . made by an executive agency for . . . the procurement of services.” 41 U.S.C.
    § 7102(a). Under the CDA, it is a jurisdictional prerequisite that the CO issue a final written
    decision on any claim by the contractor before an action is brought in this court. See
    
    id. § 7103(a),
    (d); M. Maropakis Carpentry, Inc. v. United States, 
    609 F.3d 1323
    , 1327 (Fed. Cir.
    2010). But a contractor is not required to file its own claim with the CO before challenging a
    claim by the government in this court, so long as in the CO has issued a final decision on the
    government’s claim. See Placeway Constr. Corp. v. United States, 
    920 F.2d 903
    , 906 (Fed. Cir.
    17
    1990); Bechtel Nat’l, Inc. v. United States, 
    137 Fed. Cl. 423
    , 428, appeal docketed, No. 18-2055
    (Fed. Cir. June 11, 2018); Tiger Nat. Gas, Inc. v. United States, 
    61 Fed. Cl. 287
    , 292–93 (2004).
    Here, as discussed, the government issued final decisions on its own claims related to
    DSC in June 2011. Further, the CO issued final decisions denying Boeing’s DSC and DPC
    claims in May 2012. The Court therefore has jurisdiction over this case.
    II.    Standards
    A.      Motion for Summary Judgment
    The standards for granting summary judgment are well established. Summary judgment
    may be granted where there is no genuine issue of material fact and the movant is entitled to
    judgment as a matter of law. Rule 56(a) of the Rules of the Court of Federal Claims; Anderson v.
    Liberty Lobby, Inc., 
    477 U.S. 242
    , 250 (1986). A fact is material if it “might affect the outcome
    of the suit under the governing law.” 
    Anderson, 477 U.S. at 248
    . An issue is genuine if it “may
    reasonably be resolved in favor of either party.” 
    Id. at 250.
    The moving party bears the burden of demonstrating the absence of any genuine issue of
    material fact. Conroy v. Reebok Int’l, Ltd., 
    14 F.3d 1570
    , 1575 (Fed. Cir. 1994). All significant
    doubts regarding factual issues must be resolved in favor of the party opposing summary
    judgment. Mingus Constructors, Inc. v. United States, 
    812 F.2d 1387
    , 1390 (Fed. Cir. 1987).
    “Once the moving party has satisfied its initial burden, the opposing party must establish a
    genuine issue of material fact and cannot rest on mere allegations, but must present actual
    evidence.” Crown Operations Int’l, Ltd. v. Solutia Inc., 
    289 F.3d 1367
    , 1375 (Fed. Cir. 2002)
    (citing 
    Anderson, 477 U.S. at 248
    ).
    Further, “a claimant’s motion for summary judgment should be denied when any defense
    presents significant fact issues that should be tried.” 10B Charles Alan Wright et al., Federal
    Practice and Procedure § 2734 (4th ed. 2018). The government, however, ultimately bears the
    burden of proof with respect to its affirmative defense. Energy Nw. v. United States, 
    91 Fed. Cl. 531
    , 554 (2010) (citing Siverson v. United States, 
    710 F.2d 557
    , 560 (9th Cir. 1983)), aff’d in
    part, rev’d in part, vacated in part on other grounds, 
    641 F.3d 1300
    (Fed. Cir. 2011); cf.
    Raytheon Co. v United States, 
    747 F.3d 1341
    , 1352 (Fed. Cir. 2014) (observing that “the
    Government bears the burden of proving that a contractor’s accounting practices do not comply
    with the CAS”). Thus, where the plaintiff has moved for summary judgment and the government
    has asserted an affirmative defense, the “plaintiff bears the burden of persuading the court that,
    with respect to those issues on which [the government] bears the burden of proof at trial, [the
    government’s] evidence is insufficient to establish at least one essential element of [its]
    affirmative defense.” McDonald v. United States, 
    13 Cl. Ct. 255
    , 259 (1987).
    B.      Breach of Contract
    The elements of a breach of contract claim are familiar: the plaintiff must establish (1)
    the existence of a valid contract between the parties; (2) an obligation or duty arising from that
    contract; (3) a breach of that duty; and (4) damages caused by that breach. San Carlos Irrigation
    & Drainage Dist. v. United States, 
    877 F.2d 957
    , 959 (Fed. Cir. 1989). Further, contract
    interpretation presents a question of law. See Jowett, Inc. v. United States, 
    234 F.3d 1365
    , 1367–
    18
    68 (Fed. Cir. 2000). “In interpreting a contract,” the court “begin[s] with the plain language” and
    “give[s] the words of the agreement their ordinary meaning unless the parties mutually intended
    and agreed to an alternative meaning.” 
    Id. at 1368
    (first quoting McAbee Constr. Inc. v. United
    States, 
    97 F.3d 1431
    , 1435 (Fed. Cir. 1996), then quoting Harris v. Dep’t of Veterans Affairs,
    
    142 F.3d 1463
    , 1467 (Fed. Cir. 1998)). The court aims to “interpret the contract in a manner that
    gives meaning to all of its provisions and makes sense,” 
    id. (quoting McAbee,
    97 F.3d at 1435),
    considering “the intent of the parties at the time they contracted, as evidenced by the contract
    itself,” Greco v. Dep’t of the Army, 
    852 F.2d 558
    , 560 (Fed. Cir. 1988).
    C.       Appeal from a CO’s Decision Under the CDA
    An appeal from a CO’s decision under the CDA “proceed[s] de novo” in this court. 41
    U.S.C. § 7104(b)(4). Thus, in such an appeal, “the findings of fact in [the CO’s] decision . . . are
    not entitled to any deference,” and “[t]he contractor has the burden of proving the fundamental
    facts of liability and damages de novo.” Wilner v. United States, 
    24 F.3d 1397
    , 1401 (Fed. Cir.
    1994); see also Meridian Eng’g Co. v. United States, 
    885 F.3d 1351
    , 1360 (Fed. Cir. 2018). In
    other words, “the parties start in court . . . with a clean slate.” 
    Wilner, 24 F.3d at 1402
    .
    III.   Merits
    As noted, the existence of a genuine factual dispute precludes the grant of summary
    judgment. Therefore, Boeing cannot succeed on its motion if there is a genuine factual dispute
    regarding whether the government’s refusal to pay the DSC CLINs and to negotiate and make
    DPC payments constitutes a breach of the ELC and ELS contracts.
    The government argues that there is such a dispute because the issue of whether the DSC
    and DPC costs are allowable (and, thus, legally payable) is a factual one. The root of this
    argument is its assertion that the DSC and DPC costs are not allowable unless Boeing’s lot
    accounting practice (from which they are unquestionably derived) complied with GAAP, and
    that Boeing’s GAAP compliance is a genuinely disputed question of fact.
    Boeing takes the position that, as a matter of law, the government’s affirmative defense
    of illegality can succeed only if paying the DSC and DPC costs would be “plainly and palpably”
    illegal—i.e., if the costs were plainly and palpably unallowable. And, it asserts, there is no
    genuine dispute that they were not.
    Further, it contends that, in any event, Boeing’s GAAP compliance is not relevant to the
    allowability of the DSC and DPC costs under any standard; and that, even if it were, there is no
    genuine factual dispute regarding Boeing’s GAAP compliance because GAAP allows for a range
    of reasonable accounting practices, and the government has not shown that Boeing’s accounting
    choices could be considered unreasonable.
    For the reasons discussed below, the Court concludes that the “plain and palpable”
    standard advanced by Boeing is inapplicable here. Further, the Court concludes that if Boeing’s
    accounting practices did not comply with GAAP, the DPC and DSC costs are unallowable costs,
    such that the government would prevail on its affirmative defense to breach of contract. In
    addition, the Court concludes that genuine factual disputes exist regarding Boeing’s GAAP
    compliance. Finally, the factual background and issues in this case are exceptionally complex
    19
    and the Court believes that its understanding of those issues would be enhanced if the case were
    tried rather than decided on summary judgment. Accordingly, Boeing’s motion for summary
    judgment is DENIED.
    A.      Boeing’s Reliance Upon the “Plain and Palpable” Standard Is Misplaced
    Boeing first argues that, as a matter of law, the government’s affirmative defense of
    illegality cannot succeed unless the government’s promises to pay the DSC costs and to negotiate
    and pay the DPC costs were “plainly and palpably” illegal. Thus, under Boeing’s theory, if the
    Court were to ultimately determine that the payment provisions were illegal, but not plainly and
    palpably so, the Court would be compelled to award it damages for breach of contract on Counts
    I and II of its complaint.25 For the reasons set forth below, Boeing’s legal argument lacks merit.
    1.      Contractual Payment Provisions That Are Inconsistent with Law Are
    Unenforceable
    It is well established that contracting officers lack the authority to bind the government to
    contractual payment provisions that are contrary to statute or regulation (including the FAR), and
    that such provisions are therefore not enforceable. See Barrett Ref. Corp. v. United States, 
    242 F.3d 1055
    , 1060 (Fed. Cir. 2001) (payment clause that did not comply with the FAR was
    “unauthorized and unenforceable”); Urban Data Sys., Inc. v. United States, 
    699 F.2d 1147
    ,
    1151–53 (Fed. Cir. 1983) (describing such provisions as “defect[ive]” and non-payable, and
    observing that the government “had no power to enter into the challenged price terms”);
    Yosemite Park and Curry Co. v. United States, 
    582 F.2d 552
    , 560 (Ct. Cl. 1978) (observing that
    where “the provisions in the express, written contract . . . are in violation of the F[A]R . . . it is
    clear that the Government c[an] no longer be bound by th[o]se terms”); cf. Fluor Enters., Inc. v.
    United States, 
    64 Fed. Cl. 461
    , 491–92 (2005) (“[A] government agency can not [sic] validly
    contract to pay funds in contravention of a federal statute because any ‘payment of funds from
    the Treasury must be authorized by a statute.’” (quoting Office of Pers. Mgmt. v. Richmond, 
    496 U.S. 414
    , 424 (1990))).
    Thus, because contracting officers lack the authority to bind the government to illegal
    payment provisions, a court will not award damages for breach of contract based on such
    provisions. In Yosemite Park, for example, the government defended against a breach of contract
    claim by asserting that certain payment terms to which the government had agreed (and under
    which the plaintiff had been performing) were inconsistent with applicable procurement statutes
    and 
    regulations. 582 F.2d at 555
    . The court of appeals held that the provisions were incompatible
    with the legal authority the government had cited and ruled that the payment terms were
    therefore unenforceable as written. 
    Id. at 560–61.
    Similarly, in Barrett Refining, the parties had
    agreed to a price escalation clause that was inconsistent with governing procurement 
    law. 242 F.3d at 1060
    . Because that clause was unenforceable, the court concluded that the plaintiff could
    25
    Indeed, the gravamen of Boeing’s summary judgment motion is that there is no genuine
    dispute of fact that the agreements were not plainly and palpably illegal, such that the Court
    should grant summary judgment in its favor. See Pls.’ Mem. in Supp. of Mot. for Summ. J. on
    Counts I & II of Suppl. Compl. (Pls.’ Mem.) at 20, 39–40, ECF No. 116-1.
    20
    not claim damages under the contract for its breach. See 
    id. at 1060
    & n.2 (observing that “[t]he
    determination . . . that only the price escalation term was unenforceable and invalid, and that the
    entire contract was not invalid, [wa]s consistent with our case law”).
    It follows from these cases that if the payment terms at issue here—i.e., the terms
    regarding the payment of DSC and DPC costs—mandated payment contrary to applicable
    regulations, the CO lacked the authority to bind the government to them. It further follows that to
    the extent that such authority was lacking, Boeing cannot recover breach of contract damages
    based on the government’s refusal to pay those costs.26
    2.      The Plain and Palpable Illegality Standard is Not Applicable
    Notwithstanding the foregoing, Boeing contends that even if the payment terms at issue
    in this case violated the applicable regulations, they may still be enforced through a breach of
    contract action, unless they were plainly and palpably illegal. See Pls.’ Mem. at 20; Pls.’ Reply
    in Supp. of Mot. for Summ. J. on Counts I & II of Suppl. Compl. (Pls.’ Reply) at 4, ECF No. 127
    (asserting that “the Government must show that the illegality . . . was so obvious at the time of
    contracting that it was unreasonable for either the contracting officer or the contractor to view
    the agreement as lawful” (quotation omitted)). However, the cases upon which it relies in support
    of this contention in its opening brief—United States v. Amdahl Corp., 
    786 F.2d 387
    (Fed. Cir.
    1986), and John Reiner & Co. v. United States, 
    325 F.2d 438
    (Ct. Cl. 1963)—are inapposite, as
    are the other subsidiary cases it cites in its reply brief.
    Both Amdahl and John Reiner arose following the cancellation of contract awards after
    competitors lodged successful bid protests. In both cases, it had been determined that the awards
    were “made contrary to statutory or regulatory requirements.” See 
    Amdahl, 786 F.2d at 391
    ,
    394–95; John Reiner & 
    Co., 325 F.2d at 439
    –40. In both cases, the issue was the effect of the
    illegality of the contract award upon claims that flowed from the cancellation of the illegally
    awarded contracts.
    In Reiner, a contract awardee brought suit after an agency cancelled its contract award
    upon the recommendation of the Comptroller General. 
    See 325 F.2d at 439
    –40. The Comptroller
    General had concluded that the award was improper, reasoning that the solicitation “did not
    adequately inform bidders as to how they should bid with respect to delivery dates.” 
    Id. at 439.
    The Court of Claims stated that the question before it was “whether the award was illegal and
    void so that the plaintiff cannot found a court action upon it.” 
    Id. at 440.
    Citing concerns of
    fairness to the contractor, it held that “the court should ordinarily impose the binding stamp of
    26
    It bears noting, however, that while the plaintiffs in Yosemite Park and Barrett Refining could
    not recover under the terms of the contract, they were not left entirely without a remedy. In
    Yosemite Park, the court held that the plaintiff should be provided relief on “a quantum meruit
    [basis] for the reasonable value of the services received by 
    defendant.” 582 F.2d at 560
    . And in
    Barrett Refining, the court of appeals held that the plaintiff could receive monetary relief on a
    quantum valebant 
    basis. 242 F.3d at 1060
    –61. Quantum meruit relief applies to services, and
    quantum valebant applies to goods. See Urban Data 
    Sys., 699 F.2d at 1154
    n.8.
    21
    nullity [on a contract award] only when the illegality is plain.” 
    Id. It then
    found that the award
    before it was not plainly illegal and so should not have been deemed a nullity. 
    Id. Nonetheless, the
    Court of Claims did not award the plaintiff damages for breach of
    contract. Instead, it converted the rescission of the contract into a termination for convenience
    under the contract’s termination for convenience clause, and made an award to the plaintiff based
    on the cost of performance plus a reasonable profit. See 
    id. at 442–44.
    In Amdahl, a disappointed potential bidder successfully protested a sole-source award
    before the Board of Contract Appeals (BCA) on the ground that the award was illegal, and the
    government challenged the remedy that the BCA had ordered. 
    See 786 F.2d at 389
    . As in Reiner,
    the court of appeals “start[ed] with the proposition that the failure of a contracting officer to
    comply with statutory requirements in making an award renders the contract a nullity.” 
    Id. at 392.
    Nonetheless, the court observed, “in many circumstances it would violate good conscience
    to impose upon the contractor all economic loss from having entered an illegal contract.” 
    Id. at 393.
    Therefore, it noted, where “the invalidity of the contract award was not plain,” it may be
    “treated as valid up to the time of cancellation,” and the contractor may recover “the cost of
    performance plus a reasonable profit on those costs.” 
    Id. at 394
    (emphasis added) (discussing
    
    Reiner, 325 F.2d at 440
    ).
    Importantly, the court of appeals explained that in such circumstances, “[t]he contractor
    is not compensated under the contract, but rather under an implied-in-fact contract.” 
    Id. at 393;
    see also 
    id. (observing that,
    in Reiner, “[n]otwithstanding the ‘deemed’ initial lawfulness of the
    contract, the . . . court did not award damages for its breach”); Trilon Ed. Corp. v. United States,
    
    578 F.2d 1356
    , 1359–62 (Ct. Cl. 1978) (where agency reversed initial determination of
    responsibility under procurement regulations and cancelled contract, contractor was not left
    without remedy; cancellation, while erroneous, was not plainly so and was made in good faith,
    and thus proper remedy was to convert cancellation into termination for convenience so that
    contractor could recover expenditures and reasonable profit up to date of termination).
    Amdahl and Reiner are distinguishable from this case. Each involved the cancellation of
    a contract award based on its illegality; and in each case, the court of appeals discussed the
    concept of plain and palpable illegality only in the context of securing equitable relief following
    such a cancellation, such as conversion of a cancellation into a termination for convenience. This
    case, of course, does not concern the legality of a contract award. Nor does it involve the
    government’s decision to cancel the contract in its entirety. Rather, this case—like Yosemite
    Park, Barrett Refining, and Urban Systems, concerns the legality and enforceability of specific
    contractual payment provisions. The “plain and palpable” standard was not applied in those
    cases.27
    27
    In fact, in Amdahl, the court of appeals cited Urban Data Systems and Yosemite Park as
    supporting the proposition that “a contractor assume[s] the risk that an agency ha[s] actual
    authority to enter into the bargain to which the parties 
    agreed.” 786 F.2d at 393
    (quotations
    omitted).
    22
    In another case upon which Boeing relies in its reply, American Science & Engineering,
    Inc. v. United States, 
    663 F.2d 82
    (Ct. Cl. 1981), the Department of Health, Education and
    Welfare cancelled a three-year license agreement it had entered with the plaintiff, on the grounds
    that the license “was granted without authority and in violation of the Federal Procurement
    Regulations.” 
    Id. at 86.
    The plaintiff moved for summary judgment on liability, contending that
    the cancellation of the license was wrongful. 
    Id. at 83.
    In response, the government argued that
    because the license was illegally granted, it was “a nullity” and the government therefore had “no
    liability for its cancellation.” 
    Id. at 87.
    The court rejected the government’s argument that the license agreement was “a nullity.”
    
    Id. Citing Reiner,
    it observed that “[i]t is now settled law that this court will not declare a
    contract between the government and a private party void ab initio unless there was ‘plain
    illegality’ in the contract.” 
    Id. And not
    only had this standard not been met, the court concluded,
    but in fact the original decision to award the license agreement fell within the bounds of the
    discretion afforded to the agency under its regulations. 
    Id. at 87–89.
    Thus, because the agency’s
    decision to enter the license agreement was based on a permissible exercise of discretion and was
    not plainly illegal (or illegal at all), the court granted the plaintiff’s motion for summary
    judgment as to liability, remanding the case to the trial court for a determination of damages. 
    Id. at 89–90.
    American Science is also of no assistance to Boeing. As in Amdahl and John Reiner, the
    plain and palpable illegality standard was discussed in the context of addressing whether a
    contract award was lawful, and whether, if it was not, the contract should be considered void ab
    initio. As noted above, this case does not involve a claim that a contract award was illegal.
    Further, the government does not assert that the ELC and ELS contracts were void ab initio.
    Instead, it contends that the payment provisions in those contracts are unenforceable as written
    because they are contrary to law. This case is thus controlled by the reasoning in Yosemite Park,
    Barrett Refining, and Urban Data Systems, and not the contract award cases.
    Similarly, another case cited by Boeing in its reply fails to provide support for its
    argument. In Total Medical Management, Inc. v. United States, 
    104 F.3d 1314
    (Fed. Cir. 1997),
    the plaintiff entered a renewable MOU with an Army Hospital in 1988 to provide internal
    medicine services at specified rates for beneficiaries of the Civilian Health and Medical Program
    of the Uniformed Services (CHAMPUS). 
    Id. at 1317.
    Congress amended the CHAMPUS law in
    1989 to require that all charges by physicians and other individual providers be adjusted by the
    Medicare Economic Index (MEI). 
    Id. This change
    was also reflected in newly issued regulations.
    
    Id. Subsequent and
    renewed MOUs between plaintiff and the Army did not, however, reflect the
    MEI limitation. See 
    id. at 1317–18.
    Nonetheless, beginning in 1990, the Army (through its
    payment processer) applied the MEI limitation to reimbursements under those MOUs. 
    Id. at 1318.
    The plaintiff therefore brought suit against the government in the Court of Federal Claims,
    arguing that the MOUs were not inconsistent with applicable law and seeking damages based on
    the difference between the rates specified in the MOUs and those it was actually paid. See 
    id. The Court
    of Federal Claims granted plaintiff’s motion for summary judgment as to liability. 
    Id. at 1319.
    The court of appeals reversed. 
    Id. at 1320–21.
    It concluded that “at the time each of the
    [MOUs] was entered into (or renewed),” they were in “direct conflict” with the applicable
    23
    CHAMPUS regulations and that “the illegality was ‘plain’ under the Reiner test” because
    plaintiff “was on constructive and actual notice that the CHAMPUS regulatory scheme would be
    used in determining payment rates.” Id. (quoting 
    Reiner, 325 F.2d at 440
    ). “Since the contracts
    were plainly illegal,” the court of appeals concluded, “they were void ab initio.” 
    Id. at 1321
    (quotation omitted). Accordingly, the court of appeals held that plaintiff’s complaint should be
    dismissed for failure to state a claim. 
    Id. Total Medical
    is of no assistance to Boeing here because the decision did not address
    what relief, if any, would have been available to the plaintiff if the payment provision in the
    contract were found illegal, but not plainly and palpably so. Thus, in short, neither Total Medical
    nor any of the other decisions cited by Boeing hold that the government cannot successfully
    defend against a breach of contract claim based on illegality unless the illegality of the provision
    at issue is plain and palpable.
    Finally, Boeing’s reference to and reliance on the Winstar line of cases—which it claims
    presented “remarkably similar” facts—is fundamentally flawed. In those cases, the contracts at
    issue provided favorable accounting treatment to certain banks; Congress, through subsequent
    legislation, rendered that treatment unlawful. See United States v. Winstar Corp., 
    518 U.S. 839
    ,
    858 (1996) (plurality opinion). The Court held that notwithstanding the change in the law, the
    government was liable for breach of its agreement. 
    Id. at 870.
    Boeing observes that “[u]nder Winstar, the Government is liable for breaching its
    agreements even where Congress has changed the law to make them illegal.” Pls.’ Reply at 8.
    “[I]t necessarily follows,” Boeing then asserts, “that the Government is liable for breaching its
    agreements where the Executive Branch unilaterally changes its own interpretation of regulations
    in an attempt to make them illegal.” 
    Id. Therefore, according
    to Boeing, Winstar “reinforces the
    heightened showing that the Government must make to avoid its express obligations on grounds
    of regulatory illegality.” 
    Id. This line
    of reasoning suffers from multiple defects. For one, the fact that the government
    has changed its own view of the legality of the payment provisions at issue in this case is not
    what would “make them illegal” and therefore unenforceable. Their legality and enforceability is
    a matter for judicial determination and is not based on the government’s views. Further, this case
    is not “remarkably similar” to Winstar; it is materially very different. In this case, the
    government’s authority to agree to the payment provisions at the time it executed the relevant
    contracts is the matter in dispute. In Winstar, there was no question that the government had the
    authority to agree to the accounting treatment at issue at the time it entered the contract. The
    issue in Winstar was the effect of the subsequent change in law on the obligations imposed under
    that authorized agreement. Winstar, in short, does not assist Boeing’s case.28
    28
    In addition to vainly seeking support in Winstar, Boeing warns that if the plain and palpable
    standard is not applicable to cases like the present one, “the confidence that a contractor could
    have in its contracts with the Government” would be “radically undermine[d].” Pls.’ Reply at 3.
    But as the Yosemite Park, Barrett Refining and Urban Data Systems decisions illustrate, the
    Court is not breaking new ground or upsetting settled expectations in ruling that where a
    payment provision in a government contract is illegal it will not be enforced. Further, as noted, a
    24

    For the reasons discussed above, the government is not required to prove the “plain and
    palpable illegality” of the payment provisions at issue in order to prevail on its defense to
    Boeing’s breach of contract claim. The Court therefore turns to the question of whether—
    applying the appropriate standard—Boeing has shown the absence of a dispute as to whether the
    payment terms at issue in this case are not compliant with law, such that it is entitled to summary
    judgment.
    B.       To Be Allowable, Boeing’s Accounting for the DSC and DPC Costs Was
    Required to Be GAAP-Compliant
    Under FAR 31.201–2(a), “[a] cost is allowable only when [it] complies with” the
    “[s]tandards promulgated by the CAS Board, if applicable,” or “otherwise, generally accepted
    accounting principles and practices appropriate to the circumstances,” i.e., GAAP.29 See 
    id. § 31.201–2(a)(3).
    Further, costs must comply with “[a]ny [express] limitations set forth” in
    subpart 31.2. 
    Id. § 31.201–2(a)(5).
    One of these express limitations, set forth in FAR 31.205–23,
    makes unallowable any “excess of costs over income under any other contract.” 
    Id. contractor is
    not entirely without a remedy where a payment provision is ruled illegal. To the
    contrary, in appropriate cases, a contractor may be “entitled to reimbursement on a quantum
    valebant basis for the reasonable value in the marketplace of the supplies and concomitant
    services.” Urban Data 
    Sys., 699 F.2d at 1154
    ; see also Barrett 
    Ref., 242 F.3d at 1059
    –60;
    Yosemite 
    Park, 582 F.2d at 560
    . Whether or how that principle applies on the facts of this case
    has not been briefed by the parties and is not within the scope of the motion for summary
    judgment, which concerns liability on the contract.
    29
    The term GAAP encompasses the corpus of “conventions, rules, and procedures that define
    accepted accounting practice at a particular point in time.” See Shalala v. Guernsey Mem’l
    Hosp., 
    514 U.S. 87
    , 101 (1995) (quotation omitted). This body of guidance is “comprise[d of] a
    hierarchy of different sources.” Rumsfeld v. United Techs. Corp., 
    315 F.3d 1361
    , 1374 n.17
    (Fed. Cir. 2003); see also John Cibinic, Jr. et al., Cost-Reimbursement Contracting 539–40 (4th
    ed. 2014) [hereinafter Cost-Reimbursement Contracting]. At the top level of this hierarchy are
    “[e]stablished [a]ccounting [p]rinciples” set forth in “Financial Accounting Standards Board
    (FASB) Statements and Interpretations, Accounting Principles Board (APB) Opinions, and
    [American Institute of Certified Public Accountants (AICPA)] Accounting Research Bulletins.”

    n.17 (quotation omitted); see also Cost-Reimbursement 
    Contracting, supra, at 539
    –40 (same). The guidance that constitutes GAAP is not intended to “ensure identical
    accounting treatment of identical transactions,” and generally “tolerate[s] a range of ‘reasonable’
    treatments, leaving the choice among alternatives to management.” Thor Power Tool Co. v.
    Comm’r, 
    439 U.S. 522
    , 544 (1979); see also 
    id. at 542
    (observing that “[t]he primary goal of
    financial accounting is to provide useful information to management, shareholders, creditors, and
    others properly interested” and that “the major responsibility of the accountant is to protect these
    parties from being misled”). Nevertheless, GAAP may “in some cases[] prescribe mandatory
    practices.” Cost-Reimbursement 
    Contracting, supra, at 539
    .
    25
    Here, the government asserts that whether Boeing complied with CAS 406 and FAR
    31.205–23 turns on whether Boeing’s lot accounting practice (from which the DSC and DPC
    costs were derived) complied with GAAP. See Def.’s Opp’n to Pls.’ Mot. for Summ. J. on
    Counts I & II of Suppl. Compl. (Def.’s Mem.) at 14–36, ECF No. 125. The Court agrees.
    1.      CAS 406 Requires That a Contractor’s Practice of Deferring Costs for
    Expensing in Later Cost Accounting Periods Be GAAP-Compliant
    The interpretation of a regulation (such as CAS 406) is a question of law, and begins with
    the plain meaning of the regulation’s text. Lengerich v. Dep’t of Interior, 
    454 F.3d 1367
    , 1370
    (Fed. Cir. 2006) (citing Bowles v. Seminole Rock & Sand Co., 
    325 U.S. 410
    , 414–15 (1945));
    see also Chase Bank USA, N.A. v. McCoy, 
    562 U.S. 195
    , 204 (2011) (analysis of regulation’s
    meaning begins with its text); 
    Rumsfeld, 315 F.3d at 1369
    (“[T]he interpretation of CAS . . . is
    an issue of law . . . .” (citing, inter alia, Rice v. Martin Marietta Corp., 
    13 F.3d 1563
    , 1568 (Fed.
    Cir. 1993))).30
    CAS 406 addresses “the selection of the time periods to be used as cost accounting
    periods for contract cost estimating, accumulating, and reporting.” See CAS 406–20. One of
    CAS 406’s fundamental requirements31 is that the contractor “follow consistent practices in his
    selection of the cost accounting period or periods in which any types of expense[s] . . . are
    accumulated and allocated.” CAS 406–40(b). And in implementing this fundamental
    requirement, CAS 406’s techniques for application state that “[t]he practices required” of the
    contractor “shall include appropriate practices for deferrals, accruals, and other adjustments to be
    used in identifying the cost accounting periods among which any types of expense and any types
    of adjustment to expense are distributed.” CAS 406–50(b).
    When read in combination, the plain import of these provisions is that when a contractor
    elects to “distribute[]” a cost to a later cost accounting period by deferring it, it must adopt an
    “appropriate practice for deferrals” to comply with CAS 406. Further, it is clear that the
    determination of whether a practice is “appropriate” under CAS 406–50(b) is based on whether
    30
    While the interpretation of CAS involves a question of law, the court of appeals has also
    observed that “allegations of noncompliance with cost accounting standards normally raise
    questions of fact concerning the acts or omissions which allegedly constitute a violation of an
    applicable standard, upon which the Government bears the burden of proof.” 
    Raytheon, 747 F.3d at 1352
    (quotation omitted).
    31
    According to the independent CAS Board, which promulgates the CAS, the text of each
    standard includes a set of “Fundamental Requirement[s],” which supply “the broad principles or
    practices to be applied in accounting for the cost[s] covered by the Standard.” See Statement of
    Objectives, Policies[,] and Concepts, 57 Fed. Reg. 31,036, 31,041 (July 13, 1992). Each standard
    then sets forth “Techniques for Application” of the fundamental requirement. 
    Id. The described
    techniques specify “practices to be followed with respect to particular fundamental requirements
    or in particular circumstances.” 
    Id. Further, and
    of particular relevance to this case, the
    techniques for application serve to “narrow the accounting options in accordance with the
    concepts in the fundamental requirement.” 
    Id. 26 that
    practice is GAAP-compliant. In fact, the CAS Board itself has expressly linked the practices
    governed by CAS 406–50(b)—deferrals to later periods—to GAAP. Thus, the CAS Board’s
    Statement of Objectives provides that, when “assign[ing] . . . the costs of resources consumed to
    time periods . . . . in order to recognize costs in periods other than those in which cash payment is
    made,” “generally accepted accounting principles usually require deferral or accrual.” See 57
    Fed. Reg. at 31,037. Further, CAS 406 does not purport to define “appropriate practices”; and the
    Federal Circuit has held that “GAAP is an accepted supplement to CAS . . . where CAS itself
    does not decide [an] issue.” 
    Rumsfeld, 315 F.3d at 1373
    .
    Accordingly, to comply with CAS 406, Boeing’s practices for “deferrals, accruals, and
    other adjustments . . . in identifying the cost accounting periods among which any types of
    expense and any types of adjustment to expense are distributed” were required to be GAAP-
    compliant.
    Notwithstanding the foregoing, Boeing contends that CAS 406 simply does not apply to
    the DSC payments because the CAS apply only to “cost accounting practices,” and “[t]he
    payment of an agreed sum of costs . . . is . . . not itself a cost accounting practice.” Pls.’ Mem. at
    24 (citing FAR 9903.302–1). This argument is based on a distortion of the language of FAR
    9903.302–1. That regulation provides that “[t]he determination of the amount paid . . . for a unit
    of goods and services is not a cost accounting practice.” 
    Id. (emphasis added).
    It is obvious that
    “an agreed sum of costs” is not the same as “a unit of goods and services.” And there is no
    question that the agreed-upon amounts of DSC resulted from the “measurement of cost[s],” nor
    that Boeing’s deferral of the costs involved the “assignment of cost[s] to cost accounting
    periods,” both of which are defined as cost accounting practices in FAR 9903.302–1.32
    Mining a similar vein, Boeing asserts that the DSC payments are neither an
    “accumulation” nor an “allocation” of costs on the ELC contract under CAS 406. Pls.’ Mem. at
    24 (contending that the DSC costs “had already been accumulated, allocated, and inventoried
    before the ELC Contract was executed”); see also Pls.’ Reply at 13–15. This argument does not
    cohere. As described above, when Boeing deferred its costs by placing them in inventory, it
    listed them as an asset on its books, not a liability or expense. And, after the commercial launch
    market collapsed, it apparently expected to record the costs as expenses in years covered by the
    ELC contract—i.e., as costs-of-sale for launches in those years.
    CAS 406–40(b) and 406–50(b) contemplate precisely this sort of practice. See CAS 406–
    40(b) (contractor must “follow consistent practices in his selection of the cost accounting period
    or periods in which any types of expense . . . are accumulated and allocated” (emphasis added));
    CAS 406–50(b) (requiring that the contractor’s practices in this regard “include appropriate
    practices for deferrals, accruals, and other adjustments to be used in identifying the cost
    accounting periods among which . . . expense[s] and . . . adjustment[s] . . . are distributed”
    (emphasis added)). Thus, as contemplated by CAS 406, Boeing apparently deferred the expenses
    32
    Even if Boeing’s argument had merit and CAS 406 were inapplicable, FAR 31.201–2(a)(3)
    indicates that GAAP would still apply to the deferred costs. See 
    id. (costs must
    comply with the
    “[s]tandards promulgated by the CAS Board, if applicable,” or, “otherwise, generally accepted
    accounting principles and practices appropriate to the circumstances” (emphasis added)).
    27
    represented by the DSC costs and distributed them to the cost accounting periods covered by the
    ELC contract. It follows that to meet the requirements of CAS 406–50(b), Boeing had to employ
    “appropriate”—that is, GAAP-compliant—practices for those deferrals.
    2.      GAAP Determines Whether Claimed Costs Are Traceable to Losses on
    Other Contracts and Therefore Not Allowable Under FAR 31.205–23
    As noted, FAR 31.205–23 makes unallowable any “excess of costs over income under
    any other contract.” 
    Id. “The theory
    behind th[is] cost principle is that each contract stands
    alone.” Karen L. Manos, 1 Government Contract Costs & Pricing § 30:1 (2d ed. 2009)
    (observing that “the Government cannot use the contractor’s profits on another contract to reduce
    its costs on the current contract” and that “the contractor cannot use losses experienced on
    another contract to justify a higher price”).
    Boeing does not appear to dispute the government’s contention that whether the deferred
    costs constitute losses on other contracts is determined by reference to GAAP. See Def.’s Mem.
    at 34; Pls.’ Reply at 15–16. Rather, it posits that the government was permitted to pay the DSC
    costs even if they constituted losses on other contracts because the government agreed to pay
    those costs via fixed-price CLINs.33 See Pls.’ Mem. at 36 n.17; Pls.’ Reply at 15–16. Boeing
    bases this argument on FAR 31.102, which provides that when the FAR’s cost principles apply
    “in the pricing of fixed-price contracts,” the government’s objective is to “negotiate prices that
    are fair and reasonable, cost and other factors considered.” See Pls.’ Reply at 15.
    Boeing’s argument lacks merit. Under the circumstances presented here, where cost was
    essentially the sole factor in determining price, it would not be “fair and reasonable” for a CO,
    when considering “cost and other factors,” to simply ignore the fact that the relevant costs were,
    in fact, losses on other contracts. The existence of FAR 31.205–23 confirms that this is so, as
    that provision represents a determination that, as a matter of policy, losses on other contracts
    generally are not allowable. See Boeing N.A., Inc. v. Roche, 
    298 F.3d 1274
    , 1281 (Fed. Cir.
    2002) (“The concept of allowability is addressed to the question whether a particular item of cost
    should be recoverable as a matter of public policy.” (quotation omitted)). Accepting Boeing’s
    argument would permit FAR 31.102 to simply override that policy judgment where an agency
    wished to compensate a contractor for losses on other contracts via a fixed-price mechanism.
    Further, despite the fixed-price label, Boeing consistently describes the DSC payments as
    intended to “reimburse” it for the costs it incurred prior to December 2006. See Pls.’ Mem. at 4
    (asserting that the question in this case is “[w]hether the Government can avoid its contractual
    agreements to reimburse ULS for [DSC] and [DPC]”); see also 
    id. at 1,
    3, 12–14, 19, 23–24, 26,
    35, 37; Pls.’ SUMF ¶¶ 71, 99. This choice of language shows that Boeing itself understood the
    government’s agreement to pay DSC as akin to reimbursement on a cost-type contract, rather
    33
    As the government points out, the Air Force conditioned its promise to negotiate and pay the
    DPC costs on the outcome of a DCAA audit into the allocability and allowability of those costs.
    See Def.’s Mem. at 39 (citing PA 2627). And as described above, that audit found that Boeing’s
    DPC proposal was non-compliant with CAS 406. See PA 3921. Accordingly, Boeing’s argument
    on this point goes only to DSC.
    28
    than a pure fixed-price arrangement. And that understanding is also consistent with the plain
    meaning of the interrelated Lot Accounting and DSC advance agreements, upon which Boeing
    relies to establish the extent of the government’s contractual obligation to pay DSC. See Pls.’
    SUMF ¶ 114 (Lot Accounting advance agreement stating that “as of the date [of the agreement],
    the [CO] has found Lot Accounting a compliant practice,” and that “[t]his determination is not
    intended to and does not prevent the revocation, withdrawal, or other reconsideration of this
    determination if subsequent facts indicate that some aspect of this . . . practice is noncompliant
    with CAS or FAR”); 
    id. ¶ 104
    (DSC advance agreement setting forth an amount that “represents
    costs” derived from lot accounting, and stating that the DSC payments would “compensate the
    contractor for such unreimbursed expenses on a separate line item”).
    Accordingly, the Court rejects Boeing’s argument that FAR 31.205–23 is irrelevant to
    whether the DSC costs were payable under the ELC contract. Lot accounting’s GAAP-
    compliance is therefore material to determining whether Boeing’s deferred costs constituted
    losses on other contracts.
    C.      Boeing’s GAAP Compliance is Genuinely Disputed
    The court of appeals has indicated that whether a contractor’s accounting practices
    comply with GAAP generally presents a factual question. See 
    Rumsfeld, 315 F.3d at 1369
    n.6
    (observing that “as to the requirements of GAAP,” a factfinder “could properly consider expert
    testimony”). As discussed below, multiple factual questions exist regarding Boeing’s compliance
    with GAAP between 1998 and 2006, and in particular its compliance with AICPA’s Statement of
    Position (SOP) 81-1. A non-exhaustive list of these disputes, discussed in greater detail below,
    includes (1) whether, for purposes of deferring costs via average-cost accounting, SOP 81-1
    permits the combination of existing and anticipated production-type contracts; (2) if it does,
    whether Boeing’s lot accounting method (which undisputedly combined existing and anticipated
    contracts) nevertheless constituted program accounting, which is outside the scope of SOP 81-1;
    and (3) if it did not, whether Boeing otherwise failed to comply with GAAP in the course of
    holding the deferred costs in inventory. Accordingly, summary judgment in Boeing’s favor is not
    proper at this juncture.
    1.      Combining Production-Type Contracts Under ¶ 38
    First, factual disputes exist regarding whether Boeing’s lot accounting practice was a
    permissible accounting practice under SOP 81-1. That SOP sets forth accounting standards for
    what are known as “production-type” contracts.34
    Under SOP 81-1, production-type contracts are “binding agreements between buyers and
    sellers in which the seller agrees, for compensation, to perform a service to the buyer’s
    specifications.” PA 109 ¶ 12. Production-type contracts are generally complex and “long-term”
    in nature, and may “consist of legally enforceable agreements in any form.” 
    Id. at 108–09
    ¶¶ 11–
    12. Examples include contracts for projects such as “the development and production of military
    Boeing’s expert asserts that SOP 81-1 is “Category (b)” guidance in the GAAP hierarchy,
    34
    meaning it is the second-most authoritative type of guidance. See PA 4406–07.
    29
    and commercial aircraft, weapons delivery systems, space exploration hardware, and computer
    software.” 
    Id. at 106
    ¶ 1; see also 
    id. at 109
    ¶ 13.
    The “[b]asic [a]ccounting [i]ssue” SOP 81-1 addresses with respect to production-type
    contracts is “[t]he determination of the point or points at which revenue should be recognized as
    earned and costs should be recognized as expenses.” 
    Id. at 106
    ¶ 2. Production-type contracts
    warrant separate guidance on this point because the contractor must “measur[e] the results of
    relatively long-term events and allocat[e] those results to relatively short-term accounting
    periods.” 
    Id. Accounting for
    production-type contracts is thus “complicated by the need to
    evaluate continually the uncertainties inherent in the performance of contracts and by the need to
    rely on estimates of revenues, costs, and the extent of progress toward completion.” 
    Id. Paragraphs 35–38
    of SOP 81-1 specify the circumstances under which production-type
    contracts may be combined for accounting purposes. See 
    id. at 116–17.
    Of particular relevance
    here, ¶ 38 provides that production-type contracts (or segments of such contracts) may “be
    combined into groupings such as production lots or releases for the purpose of accumulating and
    allocating production costs to units produced or delivered on the basis of average unit costs,” so
    long as (1) “[t]he contracts are with one or more customers for the production of substantially
    identical units of a basic item produced concurrently or sequentially,” and (2) “[r]evenue on the
    contracts is recognized on the units-of-delivery basis of applying the percentage-of-completion
    method.”35 
    Id. at 117.
    One dispute in this case concerns whether combining existing and anticipated contracts
    for launch services, as was done under Boeing’s lot accounting practice, was appropriate under
    ¶ 38. Notably, although SOP 81-1 specifically discusses “anticipated” contracts elsewhere (i.e.,
    at ¶¶ 14, 73, 74, and 75), it does not mention them in ¶ 38. The parties draw differing
    conclusions about the import of that drafting choice. See Def.’s Mem. at 16–17; Pls.’ Reply at
    17–18. Thus, the government’s expert opines that anticipated contracts may not be combined
    with existing contracts under ¶ 38. PA 4635–36; 4686–95. Boeing’s experts reach the opposite
    conclusion. 
    Id. at 4428–30;
    4560–63. The existence of this dispute precludes summary judgment,
    for the Court cannot resolve it without hearing and weighing the expert testimony.
    2.      Program Accounting
    Further, even if it is appropriate under ¶ 38 to combine anticipated and existing
    production-type contracts, the question remains whether combining those two types of contracts
    suggests that Boeing was actually employing “program accounting,” which is expressly excluded
    from SOP 81-1’s coverage. 
    Id. at 109–10
    ¶ 14. Thus, ¶ 14 of SOP 81-1 states that the SOP does
    not cover “[c]ontracts included in a program and accounted for under the program method of
    accounting.” 
    Id. at 109.
    And it further explains that “[f]or accounting purposes, a program
    consists of a specified number of units of a basic product expected to be produced over a long
    35
    Under the SOP, contractors may elect one of two acceptable means of accounting for
    production-type contracts—the “Percentage of Completion Method” and the “Completed-
    Contract Method.” See PA 111–12 ¶ 22; 
    id. at 115
    ¶ 30. The “units of delivery” method is a
    variation on the percentage of completion method. See 
    id. at 111–12
    ¶ 22.
    30
    period in a continuing production effort under a series of existing and anticipated contracts.” 
    Id. at 109–10
    .
    The Court notes that AICPA’s Guide for Audits of Federal Government Contractors
    (Audit Guide) states that “[i]n practice, the program method of accounting has had very limited
    applications, such as in major commercial aircraft production sold to commercial (or, in some
    cases, commercial and government) customers.” See DA 1383 ¶ 3.59. This is so “because of
    (a) the significant uncertainties associated with making reasonably dependable estimates of the
    total number of units to be produced and sold, (b) the length of time to produce and sell them,
    and (c) the associated production costs and selling prices.” 
    Id. Further, the
    Audit Guide points
    out, “[t]he unique aspects of the government procurement process make estimating the market
    and timing of deliveries extremely difficult” and place other restrictions on the contractor. 
    Id. ¶¶ 3.60
    to .61. “Therefore,” the guide concludes, “the program method of accounting is not
    appropriate for government contracts or subcontracts except as provided in paragraph 3.59”—
    i.e., in the context of major commercial aircraft production. 
    Id. ¶ 3.61.
    Here, the record is replete with evidence that some individuals involved with Boeing’s lot
    accounting practice either considered it to be program accounting or expressed concern that it
    deviated from ¶ 38’s prescriptions for combining contracts. See, e.g., 
    id. at 1558
    (internal Boeing
    draft explanation of Lot 1 titled “Lot-Costing/Program-Accounting,” which states that Boeing
    “decided to use the program accounting method for the Delta IV product line” and that “[t]he
    program accounting method is not new to Boeing”); 
    id. at 913
    (internal Boeing email stating that
    “lot accounting, in my opinion, is very similar to program accounting”); 
    id. at 914
    (internal
    Boeing email stating that “[d]eferred costs is a concept that is usual for program accounting
    situations, but not for lot accounting situations”); 
    id. at 1108
    (letter from ULA’s controller
    stating that “[l]ot accounting is considered ‘program accounting’”); cf. PA 2643 (ULA
    description of lot accounting observing that “[t]he Production Lot Accounting methodology is
    rooted in aircraft manufacturing where high factory throughput and low cost differential between
    manufactured units describes the production landscape,” and that “[a] similar production
    landscape was forecasted within the Launch Vehicle industry in 1999,” but failed to materialize).
    Thus, even assuming that ¶ 38 permits combining anticipated and existing contracts,
    determining whether the manner in which Boeing combined existing and anticipated contracts
    constituted program accounting, rather than a permissible combination under ¶ 38, also presents
    a disputed question of fact making this case unsuitable for disposition by summary judgment. 36
    3.      Holding the Deferred Costs in Inventory
    Finally, genuine factual disputes exist regarding whether Boeing’s lot accounting practice
    complied with the applicable GAAP directives that govern when deferred costs may be held in
    inventory. These directives include (1) Chapter 4 of Accounting Research Bulletin (ARB) 143,
    which describes the procedures that generally apply when accounting for inventory, see PA 153–
    36
    One of Boeing’s experts implicitly acknowledges the existence of this dispute. See PA 4467
    (opining that he disagreed with the government’s expert’s analysis “for the simple reason that
    Boeing was not applying program accounting on the Delta IV program”).
    31
    58; (2) Statement of Financial Accounting Standards (SFAS) No. 5, which provides additional
    guidance on such accounting, see 
    id. at 191;
    and (3) portions of SOP 81-1—specifically, ¶¶ 69–
    75 and ¶¶ 85–89—which discuss these principles in the context of production-type contracts, see
    
    id. at 126–28,
    132–33.
    As relevant here, ¶ 8 of ARB 43 states that “in accounting for inventories, a loss should
    be recognized whenever the utility of goods is impaired by damage, deterioration, obsolescence,
    changes in price levels, or other causes.” 
    Id. at 156.
    This rule is applied because, under such
    circumstances, stating the inventory’s value at cost may not reflect “the amount properly
    chargeable against the revenues of future periods.” 
    Id. Further, ¶
    8 provides that “a loss of utility
    is to be reflected as a charge against the revenues of the period in which it occurs.” 
    Id. SFAS No.
    5 provides further guidance on when a company must recognize the
    impairment of an asset, such as inventory, under circumstances that “involv[e] uncertainty as to
    possible . . . loss.” 
    Id. at 191
    ¶ 1. In particular, ¶ 8 states that “[a]n estimated loss . . . shall be
    accrued by a charge to income” when “[i]nformation . . . indicates that it is probable that an asset
    ha[s] been impaired,” meaning that “it [is] probable that one or more future events will occur
    confirming the fact of the loss.”37 
    Id. at 192–93.
    And as to inventories specifically, the statement
    observes that “impairment is recognized . . . when the utility of inventory is no longer as great as
    its cost.” 
    Id. at 207
    ¶ 75 (emphasis omitted).
    Thus, as the parties agree, ARB 43 and SFAS No. 5 dictate that, in general, a loss should
    be recognized when costs held in inventory are not “probable of recovery.” See Def.’s Mem. at
    24; PA 4428 (Boeing’s expert opining that “GAAP allows a company to carry costs in
    inventory . . . so long as it reasonably determines that their recovery is probable”).
    Finally, in the context of production-type contracts in particular, ¶ 72(g) of SOP 81-1
    observes that “[i]nventoriable costs should not be carried at amounts that when added to the
    estimated cost to complete are greater than the estimated realizable value of the related
    contracts.” 
    Id. at 127.
    Paragraphs 73–75 of SOP 81-1 further describe circumstances in which
    certain types of pre-contract costs may be deferred if their recovery is probable. See 
    id. at 127–
    28. And ¶ 88 of SOP 81-1 states that when the “estimated cost for the contract exceeds estimated
    revenue,” a “provision for loss arises.” 
    Id. at 132.
    Such a provision “should be made in the
    period in which [it] become[s] evident.” 
    Id. ¶ 85.
    Here, disputes exist regarding whether Boeing’s deferral of costs via lot accounting
    complied with the requirement that costs not be held in inventory if they are not probable of
    recovery. As described, the relevant GAAP directives provide that costs may no longer be
    deferred and held in inventory if they are no longer probable of recovery—that is, once it has
    become probable that the inventoried costs exceed the future revenues chargeable to the
    inventory.
    37
    For a loss to accrue, “[t]he amount of loss” must also “be reasonably estima[ble].” See PA
    192–93.
    32
    Assessing recoverability at any given point therefore involves examining both probable
    future revenues and probable future costs. Here, as noted above, Lot 1’s exhaustion date
    stretched far beyond Boeing’s initial assumptions, upsetting its expectations about Lot 1’s per-
    mission production costs. See, e.g., Pls.’ SUMF ¶¶ 17–18 (asserting that by July 2003, Boeing
    realized that “[a]s a result of the changes in [its] manifest assumptions, the estimated cost of each
    anticipated launch increased significantly”); PA 1752 (2006 DCAA report observing that the
    long time period covered by the lot “put[] the government at a greater [cost] risk because of the
    wide variability of [labor] costs included in the average price” for any particular mission). And
    for recovery to remain probable given high per-mission costs, revenues for missions needed to be
    correspondingly high. See, e.g., PA 868–70 (2003 document prepared by Boeing titled “Delta IV
    Re-Pricing and Anticipated Future Revenues as of Second Quarter 2003” discussing possible
    mechanisms for increasing mission prices); 
    id. at 1556–57
    (2006 document prepared by Boeing’s
    outside auditor discussing Boeing’s expectation that “the government will pay substantially more
    for future launches”).
    The record before the Court raises (but does not answer to the Court’s satisfaction) a
    number of questions about whether Boeing’s accounting decisions in this regard complied with
    GAAP. Many (but by no means all) of these questions center on the time period from mid-2003
    to 2006. For instance, documents from mid-2003 indicate that Boeing had begun to assume that
    the anticipated (but unordered) launches required to consume Lot 1’s end items would nearly all
    consist of government launches, and that its revenues on those launches would equal or exceed
    its costs. See, e.g., 
    id. at 860
    (“[T]he new strategy adopted in 2Q03 is to focus Delta IV on
    serving the US Government customer”); 
    id. at 861
    (observing that “[i]n 1Q03 Boeing alerted the
    USAF to the risk of very significant price increases on existing . . . contracts and future bids”);
    
    id. at 874–75
    (stating that Boeing “assumed that the government will be willing to pay for a
    higher price for rockets in order to retain its goal of assured access to space” and that Boeing’s
    “position is to not sell these rockets below their cost”). At the time, Boeing stated that it had “24
    firm and priced option launch services currently on contract.” 
    Id. at 869.
    By 2006, however, the number of “definitized” missions had seemingly dwindled from
    24 to 14, placing up to 10 additional missions in the category of “anticipated.” See 
    id. at 900
    (2Q
    2004 pricing review stating that Boeing had 19 definitized contracts); 
    id. at 1556
    (outside auditor
    analysis reporting that “[a]s of 3/31/06, the program has 18 firm ordered Delta IV launches”); 
    id. at 4426
    (opinion of Boeing’s expert stating that “14 Delta IV missions . . . had been ordered as of
    2006”); 
    id. at 4570
    (same). The explanation for this discrepancy is not apparent to the Court, but
    the change clearly shifted a substantial amount of deferred costs to the anticipated contracts. 38
    And as to those anticipated contracts, the record reflects that Boeing itself expressed uncertainty
    about whether future government launch funding would be sufficient to cover its costs. See, e.g.,
    DA 714 (2003 document stating “[a]llocated funds not sufficient” for “sustain[ing] 2 EELV
    providers”). Further, as discussed, the government’s acquisition strategy for the ELC and ELS
    38
    As previously noted, the Air Force transferred seven ordered launches from Boeing to
    Lockheed Martin sometime after mid-2003 based on the results of its PIA investigation, but it is
    unclear whether that partially accounts for the diminishing number of definitized missions, or
    whether Boeing re-characterized those particular missions as “anticipated” rather than
    “definitized.”
    33
    contracts stated that it would not reimburse the contractors for losses on previous contracts.
    Thus, whether it was probable between 2003 and 2006 that Boeing could recover all the deferred
    costs it had allocated to anticipated contracts in a future where the government was its only
    customer presents a disputed factual question.
    Similar questions, and others, also exist regarding whether Boeing complied with ¶¶ 73–
    75 of SOP 81-1, which (as noted) establish rules governing whether certain types of pre-contract
    costs may be deferred for later recognition. Thus, at ¶ 73, the SOP identifies several categories of
    pre-contract costs, including (among others), “learning, start-up, or mobilization costs incurred
    for anticipated but unidentified contracts.” PA 127. The SOP flags “[l]earning [and] start-up
    costs” for particular attention, as “[a] direct relationship between such costs and the anticipated
    future contracts is often difficult to establish, and the receipt of future contracts often cannot
    reasonably be anticipated.” 
    Id. at 127–28
    ¶ 74.
    Finally, at ¶ 75, the SOP prescribes differing treatments for the different types of pre-
    contract costs set forth in ¶ 73. See 
    id. at 128.
    In particular, ¶ 75(d) specifies that “[l]earning or
    start-up costs incurred in connection with existing contracts and in anticipation of follow-on or
    future contracts for the same goods or services should be charged to existing contracts.” 
    Id. (emphasis added).
    Here, the parties dispute whether the deferred costs at issue in this case include learning
    or start-up costs within the meaning of ¶¶ 73–75, which (as the SOP makes clear) may not be
    deferred and charged to anticipated contracts. See 
    id. at 4438–39
    (Boeing’s expert opining that
    the deferred costs did not include learning or start-up costs as that term is used in ¶¶ 73–75); 
    id. at 4706–07
    (government’s expert disputing this claim). This dispute is factual in nature, and thus
    also precludes the entry of summary judgment in this case.

    At bottom, the record reveals that Boeing’s lot accounting mechanism was notably
    complex even at the outset of the Delta IV program. That complexity was only amplified when
    shifting currents in the space launch market upended Boeing’s expectations about who would
    pay for launch services and how long it would take to exhaust Lot 1. Given these unique and
    complex circumstances (which the sheer volume of the record reflects), it is unsurprising that
    disputes of fact exist regarding lot accounting’s compliance with GAAP, including, but not
    limited to, the disputes described above. And because lot accounting’s GAAP compliance is
    material to the allowability of the DSC and DPC costs, and thus to whether the government
    breached the ELC and ELS contracts by refusing to pay them, Boeing’s motion for summary
    judgment must be DENIED.
    34
    CONCLUSION
    For the reasons discussed above, Boeing’s motion for summary judgment is DENIED.
    The parties shall submit a joint status report by September 28, 2018, proposing further
    proceedings in the case.
    IT IS SO ORDERED.
