    SUMMARY***
    Tax
    The panel reversed a decision of the Tax Court that
    
    26 C.F.R. § 1.482
    -7A(d)(2), under which related entities must
    share the cost of employee stock compensation in order for
    their cost-sharing arrangements to be classified as qualified
    cost-sharing arrangements and thus avoid an IRS adjustment,
    was invalid under the Administrative Procedure Act. The
    panel reasoned that the Commissioner of Internal Revenue
    did not exceed the authority delegated to him by Congress
    under 
    26 U.S.C. § 482
    , that the Commissioner’s rule-making
    authority complied with the Administrative Procedure Act,
    and that therefore the regulation is entitled to deference under
    Chevron, U.S.A., Inc. v. Natural Resources Defense Council,
    Inc., 
    467 U.S. 837
     (1984).
    Dissenting, Judge O’Malley would find, as the Tax Court
    did, that 
    26 C.F.R. § 1.482
    -7A(d)(2) is invalid as arbitrary
    and capricious.

    OPINION
    THOMAS, Chief Judge:
    In this case, we consider the validity of 
    26 C.F.R. § 1.482
    -
    7A(d)(2),1 under which related entities must share the cost of
    employee stock compensation in order for their cost-sharing
    arrangements to be classified as qualified cost-sharing
    arrangements (“QCSA”) and thus avoid an IRS adjustment.
    We conclude that the regulations withstand scrutiny under
    general administrative law principles, and we therefore
    reverse the decision of the Tax Court.
    I
    Corporations often elect to conduct business through
    international subsidiaries. Transactions between related
    companies can provide opportunities for minimizing or
    avoiding taxes, particularly when a foreign subsidiary is
    located in a low tax jurisdiction. For example, a parent
    company in a high tax jurisdiction can sell property to its
    subsidiary in a low tax jurisdiction and have its subsidiary
    sell the property for profit. The profits from those sales are
    thus taxed in a lower tax jurisdiction, resulting in significant
    tax savings for the parent. This practice, known as “transfer
    pricing” can result in United States companies shifting profits
    that would be subject to tax in America offshore to avoid tax.
    Similarly, related companies can identify and shift costs
    1
    The 2003 amendments to Treasury’s cost-sharing regulations are at
    issue. Although they are still in effect, the Code has been reorganized,
    and what was § 1.482-7 in 2003 is now numbered § 1.482-7A. To
    minimize confusion, our citations are to the current version of the
    regulations unless otherwise specified.
    6                  ALTERA CORP. V. CIR
    between American and foreign jurisdictions to minimize tax
    exposure. In recent years, United States corporations have
    used these techniques to develop intangible property with
    their foreign subsidiaries, and to share the cost of
    development between the companies.              Under these
    arrangements, a U.S. corporation might enter into a research
    and development (“R&D”) cost-sharing agreement with its
    foreign subsidiary located in a low tax jurisdiction and grant
    the offshore company rights to exploit the property
    internationally. The interplay of cost and income allocation
    between the two companies in such a transaction can result in
    significantly reduced taxes for the United States parent.
    To address the risk of multinational corporation tax
    avoidance, Congress passed legislation granting the United
    States Department of the Treasury the authority to allocate
    income and costs between such related parties. 
    26 U.S.C. § 482
    . In turn, the Secretary of the Treasury promulgated
    regulations authorizing the Commissioner of the Internal
    Revenue Service to allocate income and costs among these
    related entities. 
    26 C.F.R. §§ 1.482-0
     through 1.482-9.
    At issue before us are employee stock options, the cost of
    which the companies in this case elected not to share,
    resulting in substantial tax savings for the parent—here, the
    tax associated with over $80 million in income. The
    Commissioner contends that allocation of stock compensation
    costs between the companies is appropriate to reflect
    economic reality; Altera Corporation (“Altera”) and its
    subsidiaries contend that any cost allocation exceeds the
    Commissioner’s authority.
    Fundamental to resolution of this dispute is an
    understanding of the arm’s length standard, a tool that
    ALTERA CORP. V. CIR                       7
    Treasury developed in the mid-twentieth century to ensure
    that controlled taxpayers were taxed similarly to uncontrolled
    taxpayers. The arm’s length standard is results-oriented,
    meaning that its goal is parity in taxable income rather than
    parity in the method of allocation itself. 
    26 C.F.R. § 1.482
    -
    1(b)(1) (“A controlled transaction meets the arm’s length
    standard if the results of the transaction are consistent with
    the results that would have been realized if uncontrolled
    taxpayers had engaged in the same transaction under the same
    circumstances (arm’s length result).”). A traditional arm’s
    length analysis looks to comparable transactions among non-
    related parties to achieve an arm’s length result. The issue in
    this case is whether Treasury can permissibly allocate
    between related parties a cost that unrelated parties do not
    agree to share.
    Altera asserts that the arm’s length standard always
    demands a comparability analysis, meaning that the
    Commissioner cannot allocate costs between related parties
    in the absence of evidence that unrelated parties share the
    same costs when dealing at arm’s length. Altera argues that,
    because uncontrolled taxpayers do not share the cost of
    employee stock options, the Commissioner cannot require
    related parties to share that cost.
    The Commissioner argues that he may, consistent with
    the arm’s length standard, apply a purely internal method of
    allocation, distributing the costs of employee stock options in
    proportion to the income enjoyed by each controlled
    taxpayer. This “commensurate with income” method
    analyzes the income generated by intangible property in
    comparison with the amount paid (usually as royalty) to the
    parent. In the Commissioner’s view, the commensurate with
    income method is consistent with the arm’s length standard
    8                   ALTERA CORP. V. CIR
    because controlled cost-sharing arrangements have no
    equivalent in uncontrolled arrangements, and Congress has
    provided that the Commissioner may dispense with a
    comparability analysis where comparable transactions do not
    exist in order to achieve an arm’s length result.
    Because this case involves a challenge to regulations, the
    ultimate issue is not what the arm’s length standard should
    mean but rather whether Treasury may define the standard as
    it has. We conclude that the challenged regulations are not
    arbitrary and capricious but rather a reasonable execution of
    the authority delegated by Congress to Treasury.
    II
    At issue is Altera’s tax liability for the years 2004 through
    2007. During the relevant period, Altera and its subsidiaries
    designed, manufactured, marketed, and sold programmable
    logic devices, electronic components that are used to build
    circuits.
    In May of 1997, Altera entered into a cost-sharing
    agreement with one of its subsidiaries, Altera International,
    Inc., a Cayman Islands corporation (“Altera International”),
    which had been incorporated earlier that year. Altera granted
    to Altera International a license to use and exploit Altera’s
    preexisting intangible property everywhere in the world
    except the United States and Canada. In exchange, Altera
    International paid royalties to Altera. The parties agreed to
    pool their resources to share R&D costs in proportion to the
    benefits anticipated from new technologies.
    Altera and the IRS agreed to an Advance Pricing
    Agreement covering the 1997–2003 tax years. Pursuant to
    ALTERA CORP. V. CIR                      9
    this agreement, and consistent with the cost-sharing
    regulations in effect at the time, Altera shared with Altera
    International stock-based compensation costs as part of the
    shared R&D costs. The Treasury regulations were amended
    in 2003, and Altera and Altera International amended their
    cost-sharing agreement to comply with the modified
    regulations, continuing to share employee stock
    compensation costs.
    The agreement was amended again in 2005 following the
    Tax Court’s opinion in Xilinx, Inc. v. Commissioner,
    involving a challenge to the allocation of employee stock
    compensation costs under the 1994–1995 cost-sharing
    regulations. 
    125 T.C. 37
     (2005). The parties agreed to
    “suspend the payment of any portion of [a] Cost Share . . . to
    the extent such payment relates to the Inclusion of Stock-
    Based Compensation in R&D Costs” unless and until a court
    upheld the validity of the 2003 cost-sharing regulations. The
    following provision explains Altera’s reasoning:
    The Parties believe that it is more likely than
    not that (i) the Tax Court’s conclusion in
    Xilinx v. Commissioner, 125 T.C. [No.] 4
    (2005), that the arm’s length standard controls
    the determination of costs to be shared by
    controlled participants in a qualified cost
    sharing arrangement should also apply to
    
    Treas. Reg. § 1.482-7
    [A](d)(2) (as amended
    by T.D. 9088), and (ii) the Parties’ inclusion
    of Stock-Based Compensation in R&D Costs
    pursuant to Amendment I would be contrary
    to the arm’s length standard.
    10                 ALTERA CORP. V. CIR
    Altera and its U.S. subsidiaries did not account for R&D-
    related stock-based compensation costs on their consolidated
    2004–2007 federal income tax returns. The IRS issued two
    notices of deficiency to the group, applying § 1.482-7(d)(2)
    to increase the group’s income by the following amounts:
    2004           $ 24,549,315
    2005           $ 23,015,453
    2006           $ 17,365,388
    2007           $ 15,463,565
    The Altera group timely filed petitions in the Tax Court.
    The parties filed cross-motions for partial summary
    judgment, and the Tax Court granted Altera’s motion. Sitting
    en banc, the court held that § 1.482-7A(d)(2) is invalid under
    the Administrative Procedure Act (“APA”). Altera Corp. &
    Subsidiaries v. Comm’r, 
    145 T.C. 91
     (2015).
    The Tax Court unanimously determined that the
    Commissioner’s allocation of income and expenses between
    related entities must be consistent with the arm’s length
    standard, and that the arm’s length standard is not met unless
    the Commissioner’s allocation can be compared to an actual
    transaction between unrelated entities. The court reasoned
    that the Commissioner could not require related parties to
    share stock compensation costs because the Commissioner
    had not considered any unrelated party transactions in which
    the parties shared such costs. The court concluded that the
    agency decision-making process was fundamentally flawed
    because: (1) it rested on speculation rather than hard data and
    expert opinions; and (2) it failed to respond to significant
    public comments, particularly those identifying uncontrolled
    ALTERA CORP. V. CIR                       11
    cost-sharing arrangements in which the entities did not share
    stock compensation costs. Altera, 
    145 T.C. at
    122–31.
    The Tax Court’s decision rested largely on its own
    opinion in Xilinx, in which it held that “the arm’s-length
    standard always requires an analysis of what unrelated
    entities do under comparable circumstances.” 
    Id.
     at 118
    (citing Xilinx, 125 T.C. at 53–55). In its decision in this case,
    the Tax Court reinforced its conclusion that the
    Commissioner cannot require related entities to share stock
    compensation costs unless and until it locates uncontrolled
    transactions in which these costs are shared. Id. at 118–19.
    The court reached five holdings: (1) that the 2003
    amendments constitute a final legislative rule subject to the
    requirements of the APA; (2) that Motor Vehicle
    Manufacturers Association of the United States v. State Farm
    Mutual Auto Insurance Co., 
    463 U.S. 29
     (1983) provides the
    appropriate standard of review because the standard set forth
    in Chevron, U.S.A., Inc. v. Natural Resources Defense
    Council, Inc., 
    467 U.S. 837
     (1984), incorporates State Farm’s
    reasoned decisionmaking standard; (3) that Treasury failed to
    adequately support its decision to allocate the costs of
    employee stock compensation between related parties;
    (4) that Treasury’s failure was not harmless error; and (5) that
    § 1.482-7A(d)(2) is invalid under the APA. Id. at 115–33.
    On appeal, the Commissioner does not dispute the first
    holding regarding the applicability of State Farm, although he
    argues that the appropriate standard is more deferential and
    less empirically minded than the standard actually applied by
    the Tax Court. Nor does he claim that any error in the
    decisionmaking process, if it existed, was harmless. The
    challenged holdings—(2), (3), and (5)—are all part of the
    12                     ALTERA CORP. V. CIR
    same broader question: did Treasury exceed its authority in
    requiring Altera’s cost-sharing arrangement to include a
    particular distribution of employee stock compensation costs?
    III
    The Commissioner’s position is founded on 
    26 U.S.C. § 482
    . Because an understanding of § 482 and its history is
    integral to resolution of each of the issues raised by the
    parties, a brief overview of the statute and its history is
    important.
    At the relevant time,2 
    26 U.S.C. § 482
     appeared to provide
    a nearly limitless grant of authority to Treasury to allocate
    income between related parties:
    In any case of two or more organizations,
    trades, or businesses (whether or not
    incorporated, whether or not organized in the
    United States, and whether or not affiliated)
    2
    Section 482 was amended in December 2017 to include a third
    sentence:
    For purposes of this section, the Secretary shall require
    the valuation of transfers of intangible property
    (including intangible property transferred with other
    property or services) on an aggregate basis or the
    valuation of such a transfer on the basis of the realistic
    alternatives to such a transfer, if the Secretary
    determines that such basis is the most reliable means of
    valuation of such transfers.
    Tax Cuts and Jobs Act, Pub. L. No. 115-97, 
    131 Stat. 2054
    . Because the
    amendment postdates the operative regulations, it does not affect our
    analysis.
    ALTERA CORP. V. CIR                    13
    owned or controlled directly or indirectly by
    the same interests, the Secretary may
    distribute, apportion, or allocate gross income,
    deductions, credits, or allowances between or
    among such organizations, trades, or
    businesses, if he determines that such
    distribution, apportionment, or allocation is
    necessary in order to prevent evasion of taxes
    or clearly to reflect the income of any of such
    organizations, trades, or businesses. In the
    case of any transfer (or license) of intangible
    property (within the meaning of section
    936(h)(3)(B)), the income with respect to such
    transfer or license shall be commensurate with
    the income attributable to the intangible.
    The first sentence has remained substantively unchanged
    since 1928, Revenue Act of 1928, ch. 852, § 45, 
    45 Stat. 791
    ,
    806 (1928), and it provides the statutory authority for the
    arm’s length standard, which first appeared in the 1934 tax
    regulations, Regulations 86, Art. 45-1(b) (1935). The second
    sentence sets forth the commensurate with income standard,
    and it was added to the statute in 1986. Tax Reform Act of
    1986, Pub. L. No. 99-514, § 1231(e)(1), 
    100 Stat. 2085
    , 2562
    (1986).
    A
    From the beginning, § 482’s precursor was designed to
    give Treasury the flexibility it needed to prevent cost and
    income shifting between related entities for the purpose of
    decreasing tax liability. See H.R. REP. NO. 70-2, at 16–17
    (1927) (“[T]he Commissioner may, in the case of two or
    more trades or businesses owned or controlled by the same
    14                 ALTERA CORP. V. CIR
    interests, apportion, allocate, or distribute the income or
    deductions between or among them, as may be necessary in
    order to prevent evasion (by the shifting of profits, the
    making of fictitious sales, and other methods frequently
    adopted for the purpose of ‘milking’), and in order clearly to
    reflect their true tax liability.”); accord S. REP. NO. 70-960,
    at 24 (1928). The purpose of the statute is “to place a
    controlled taxpayer on a tax parity with an uncontrolled
    taxpayer . . . .” Comm’r v. First Sec. Bank of Utah, 
    405 U.S. 394
    , 400 (1972) (quoting 
    Treas. Reg. § 1.482-1
    (b)(1) (1971)).
    This parity is double-edged: as much as § 482 works to
    ensure controlled taxpayers are not overtaxed, the concern
    expressed on the face of § 482, even before the 1986
    amendment, is preventing tax avoidance by controlled
    taxpayers.
    After 1934, when the arm’s length standard appeared in
    the regulations—in what is essentially its modern form—
    courts did not hold related parties to the standard by looking
    for comparable transactions. For example, in Seminole
    Flavor Co. v. Commissioner, the Tax Court rejected a strict
    application of the arm’s length standard in favor of an inquiry
    into whether the allocation of income between related parties
    was “fair and reasonable.” 
    4 T.C. 1215
    , 1232 (1945); see
    also 
    id. at 1233
     (“Whether any such business agreement
    would have been entered into by petitioner with total
    strangers is wholly problematical.”); Grenada Indus., Inc. v.
    Comm’r, 
    17 T.C. 231
    , 260 (1951) (“We approve an allocation
    . . . to the extent that such gross income in fact exceeded the
    fair value of services rendered . . . .”). And in 1962, this
    Court collected various allocation standards and outright
    rejected the superiority of the arm’s length standard over all
    others:
    ALTERA CORP. V. CIR                              15
    [W]e do not agree . . . that “arm’s length
    bargaining” is the sole criterion for applying
    the statutory language of § 45 in determining
    what the “true net income” is of each
    “controlled taxpayer.” Many decisions have
    been reached under § 45 without reference to
    the phrase “arm’s length bargaining” and
    without reference to Treasury Department
    Regulations and Rulings which state that the
    talismanic combination of words—“arm’s
    length”—is the “standard to be applied in
    every case.”
    For example, it was not any less proper
    . . . to use here the “reasonable return”
    standard than it was for other courts to use
    “full fair value,” “fair price including a

    standard. In response to concerns about the undertaxation of
    multinationals, Congress considered reworking the Code to
    resolve the difficulty posed by the application of the arm’s
    length standard to related party transactions. H.R. REP. No.
    87-1447, at 28–29 (1962). However, it instead asked
    Treasury to “explore the possibility of developing and
    promulgating regulations . . . which would provide additional
    guidelines and formulas for the allocation of income and
    deductions” under § 482. H.R. CONF. REP. NO. 87-2508, at
    19 (1962), reprinted in 1962 U.S.C.C.A.N. 3732, 3739.
    Legislators believed that § 482, at least in theory, authorized
    the Secretary to employ a profit-split allocation method
    without amendment. Id.; H.R. REP. No. 87-1447, at 28–29
    (“This provision appears to give the Secretary the necessary
    authority to allocate income between a domestic parent and
    its foreign subsidiary.”).
    In 1968, following Congress’s entreaty, Treasury
    finalized the first regulation tailored to the issue of intangible
    property development in cost-sharing arrangements. 
    Treas. Reg. § 1.482-2
    (d) (1968). The novelty of the 1968
    regulations was their focus on comparability. Compare
    
    Treas. Reg. § 1.482-2
    (d)(2) (“An arm’s length consideration
    shall be in a form which is consistent with the form which
    would be adopted in transactions between unrelated parties in
    the same circumstances.”) with Regulations 86, Art. 45-1(b)
    (1935) (focusing on arm’s length results rather than arm’s
    length form). The 1968 regulations “constituted a radical and
    unprecedented approach to the problem they addressed—
    notwithstanding their being couched in terms of the ‘arm’s
    length standard,’ and notwithstanding that that standard had
    been the nominal standard under the regulations for some 30
    years . . . .” Stanley I. Langbein, The Unitary Method and the
    Myth of Arm’s Length, 30 TAX NOTES 625, 644 (1986).

    Despite the asserted focus on comparability, the arm’s
    length standard has never been used to the exclusion of other,
    more flexible approaches. Indeed, a study determined that
    direct comparables were located and applied in only 3% of
    IRS’s adjustments prior to the 1986 amendment. U.S. GEN.
    ACCOUNTING OFFICE, GGD-81-81, IRS COULD BETTER

    following the 1968 regulations involved
    a gradual realization by all parties concerned,
    but especially Congress and the IRS, that the
    [arm’s length standard], firmly established . . .
    as the sole standard under section 482, did not
    work in a large number of cases, and in other
    cases its misguided application produced
    inappropriate results. The result was a
    deliberate decision to retreat from the
    standard while still paying lip service to it.

    (“[T]he 1986 Act’s commensurate with income standard is

    standard had proven to be similarly illusory in international
    contexts. Langbein, supra, at 649.

    As controlled transactions increased in frequency and
    complexity, Congress determined that legislative action was
    necessary. The Tax Reform Act of 1986 reflected Congress’s
    18                  ALTERA CORP. V. CIR
    view that strict adherence to the arm’s length standard
    prevented tax parity.
    The House Ways and Means Committee recommended
    the addition of the commensurate with income clause because
    it was “concerned” that the current statute and regulations
    “may not be operating to assure adequate allocations to the
    U.S. taxable entity of income attributable to intangibles . . . .”
    H.R. REP. NO. 99-426, at 423 (1985). The clause was
    intended to correct a “recurrent problem”—“the absence of
    comparable arm’s length transactions between unrelated
    parties, and the inconsistent results of attempting to impose
    an arm’s length concept in the absence of comparables.” Id.
    at 423–24.
    Congress intended the commensurate with income
    standard to displace a comparability analysis where
    comparable transactions cannot be found:
    A fundamental problem is the fact that the
    relationship between related parties is
    different from that of unrelated parties. . . .
    [M]ultinational companies operate as an
    economic unit, and not “as if” they were
    unrelated to their foreign subsidiaries.
    ...
    Certain judicial interpretations of section
    482 suggest that pricing arrangements
    between unrelated parties for items of the
    same apparent general category as those
    involved in the related party transfer may in
    some circumstances be considered a “safe
    ALTERA CORP. V. CIR                    19
    harbor” for related party pricing
    arrangements, even though there are
    significant differences in the volume and risks
    involved, or in other factors. . . . [S]uch an
    approach is sufficiently troublesome where
    transfers of intangibles are concerned that a
    statutory modification to the intercompany
    pricing rules regarding transfers of intangibles
    is necessary.
    ...
    . . . There are extreme difficulties in
    determining whether the arm’s length
    transfers between unrelated parties are
    comparable. The committee thus concludes
    that it is appropriate to require that the
    payment made on a transfer of intangibles to
    a related foreign corporation . . . be
    commensurate with the income attributable to
    the intangible. . . .
    ...
    . . . [T]he committee intends to make it
    clear that industry norms or other unrelated
    party transactions do not provide a safe-harbor
    minimum payment for related party intangible
    transfers.      Where taxpayers transfer
    intangibles with a high profit potential, the
    compensation for the intangibles should be
    greater than industry averages or norms. . . .

    The Conference Committee suggested only one
    change—to broaden the sweep of the amendment so as to
    encompass domestic related party transactions—in order to
    better serve the objective of the amendment, “that the
    division of income between related parties reasonably reflect
    the relative economic activity undertaken by each . . . .” H.R.

    Treasury’s first response to the Tax Reform Act was the
    “White Paper,” an intensive study published in 1988. A Study
    of Intercompany Pricing under the Code, I.R.S. Notice 88-
    123, 1988-C.B. 458 (“White Paper”). The White Paper
    makes clear that Treasury initially understood the
    commensurate with income standard to be consistent with the
    arm’s length standard (and that Treasury understood
    Congress to share that understanding). Id. at 475. Treasury
    wrote that a comparability analysis must be performed where
    possible, id. at 474, but it also suggested a “clear and
    convincing evidence” standard for comparables, suggesting
    that a comparability analysis would rarely suffice, id. at
    477–78.
    Despite its use of the phrase “arm’s length standard,” the
    White Paper signaled a dramatic shift from the standard as it
    had been defined following the 1968 regulations. Treasury
    advanced a new allocation method, the “basic arm’s length
    return method,” id. at 488, which—contrary to its
    ALTERA CORP. V. CIR                           21
    name—would apply only in the absence of comparables and
    would essentially split profits between the related parties, id.
    at 490.4 The White Paper’s re-framing of the arm’s length
    standard was not novel:
    [D]espite the Treasury’s affirmation of the
    traditional [arm’s length standard] in its 1988
    White Paper, this narrow conception . . . was
    already obsolete by 1988 in the large majority
    of cases, insofar as the United States’
    approach to international taxation was
    concerned.      Subsequent developments,
    especially the recently issued proposed,
    temporary and final regulations under section
    482 of the Code, merely strengthened the nails
    in its coffin.
    Avi-Yonah, supra, at 94–95.
    The White Paper was silent regarding employee stock
    compensation—unsurprisingly, as the practice did not
    develop on a major scale until the 1990s. Zvi Bodie, Robert
    S. Kaplan, & Robert C. Merton, For the Last Time: Stock
    Options Are an Expense, 81 HARV. BUS. REV. 62, March
    2003, at 63, 67 (March 2003).

    Contemporary commentators understood that, by attempting
    synthesis between the arm’s length and commensurate with income
    provisions, Treasury was moving away from a view of the arm’s length
    standard as grounded in comparability. Marc M. Levy, Stanley C.
    Ruchelman, & William R. Seto, Transfer Pricing of Intangibles after the
    Section 482 White Paper, 71 J. TAX’N 38, 38 (1989); Josh O. Ungerman,

    In 1994 and 1995, Treasury issued the regulations
    challenged in Xilinx. As in previous iterations, the
    1994–1995 regulations defined the arm’s length standard as
    results-oriented, meaning that the goal is parity in taxable
    income rather than parity in the method of allocation itself.
    
    Treas. Reg. § 1.482-1
    (b)(1) (1994) (“A controlled transaction
    meets the arm’s length standard if the results of the
    transaction are consistent with the results that would have
    been realized if uncontrolled taxpayers had engaged in the
    same transaction under the same circumstances (arm’s length
    result).”). The arm’s length standard remained “the standard
    to be applied in every case.” § 1.482-1(b)(1) (1994).
    The regulations also set forth methods by which income
    could be allocated among related parties in a manner
    consistent with the arm’s length standard. § 1.482-1(b)(2)(i)
    (1994). Absent from the list of approved methods was the
    method outlined in the singular cost-sharing regulation
    separately issued in 1995, § 1.482-7. The 1995 regulation
    provided that intangible development costs included “all of
    the costs incurred by . . . [an uncontrolled] participant related
    to the intangible development area.” 
    Treas. Reg. § 1.482
    -
    7(d)(1) (1995). Beginning in 1997, the Secretary interpreted
    the “all . . . costs” language to include stock-based
    compensation, meaning that controlled taxpayers had to share
    the costs (and associated deductions) of providing employee
    stock compensation. Xilinx v. Comm’r, 
    598 F.3d 1191
    ,
    1193–94 (9th Cir. 2010).
    According to Treasury, the 1994 regulations defined the
    arm’s length standard in terms of “the results that would have
    been realized if uncontrolled taxpayers had engaged in the
    same transactions under the same circumstances.”
    Compensatory Stock Options Under Section 482 (Proposed),
    ALTERA CORP. V. CIR                      23
    
    67 Fed. Reg. 48,997
    , 48,998 (July 29, 2002). On the other
    hand, the 1995 regulation, consistent with the 1986
    Conference Report excerpted above, “implement[ed] the
    commensurate with income standard in the context of cost
    sharing arrangements” by “requir[ing] that controlled
    participants in a [QCSA] share all costs incurred that are
    related to the development of intangibles in proportion to
    their shares of the reasonably anticipated benefits attributable
    to that development.” 
    Id.
     Recognizing the potential for
    conflict between the 1994 and 1995 regulations (also
    discussed by this Court in Xilinx, as described below),
    Treasury later issued new cost-sharing regulations, the 2003
    regulations that Altera now challenges.
    IV
    We turn then, to the disputed 2003 amendments to the
    regulations, which Treasury intended to clarify rather than
    overhaul the 1994 and 1995 regulations. The clarifications
    were two-fold. First, the amendments expressly classified
    employee stock compensation as a cost to be allocated
    between QCSA participants. Compensatory Stock Options
    Under Section 482 (Proposed), 67 Fed. Reg. at 48,998; 
    Treas. Reg. § 1.482
    -7A(d)(2).         Second, the “coordinating”
    amendments clarified Treasury’s understanding that the cost-
    sharing regulations, including § 1.482-7A(d)(2), operate to
    produce an arm’s length result. Compensatory Stock Options
    Under Section 482 (Proposed), 67 Fed. Reg. at 49,000; 
    Treas. Reg. § 1.482
    -7A(a)(3).
    Altera challenges two regulations. It squarely challenges
    
    26 C.F.R. § 1.482
    -7A(d)(2). It also objects to § 1.482-
    7A(a)(3), but only insofar as it incorporates § 1.482-7A(d)(2)
    by reference.
    24                 ALTERA CORP. V. CIR
    Broadly, § 1.482-7A provides that costs are shared by
    parties to a QCSA, a controlled cost-sharing arrangement that
    meets the standards of the cost-sharing regulations and thus
    enables the participants to avoid an IRS adjustment. Section
    1.482-7A(a)(3) incorporates and attempts synthesis with the
    arm’s length standard:
    A qualified cost sharing arrangement
    produces results that are consistent with an
    arm’s length result . . . if, and only if, each
    controlled participant’s share of the costs (as
    determined under paragraph (d) of this
    section) of intangible development under the
    qualified cost sharing arrangement equals its
    share of reasonably anticipated benefits
    attributable to such development . . . .
    Section 1.482-7A(d)(2) provides that parties to a QCSA must
    allocate stock-based compensation between themselves:
    [In a QCSA], a controlled participant’s
    operating expenses include all costs
    attributable to compensation, including stock-
    based compensation. As used in this section,
    the term stock-based compensation means any
    compensation provided by a controlled
    participant to an employee or independent
    contractor in the form of equity instruments,
    options to acquire stock (stock options), or
    rights with respect to (or determined by
    reference to) equity instruments or stock
    options, including but not limited to property
    to which section 83 applies and stock options
    to which section 421 applies, regardless of
    ALTERA CORP. V. CIR                             25
    whether ultimately settled in the form of cash,
    stock, or other property.
    Altera does not challenge the allocation of other intangible
    development costs under § 1.482-7A(d).
    In determining whether Treasury’s regulation is
    permissible, we are faced with two questions: whether
    Treasury’s “decreed result [is] within the scope of its lawful
    authority,” and whether “the process by which it reache[d]
    that result [was] logical and rational.” Michigan v. EPA,
    
    135 S. Ct. 2699
    , 2706 (2015) (quoting State Farm, 
    463 U.S. at 43
    ). Consideration of these issues requires examination of
    the APA and Chevron deference.
    The Tax Court correctly held that the APA applies to
    Treasury in the context of the present controversy. See Mayo
    Found. for Med. Ed. & Res. v. United States, 
    562 U.S. 44
    , 55
    (2011) (“In the absence of [any] justification, we are not
    inclined to carve out an approach to administrative review
    good for tax law only.”).5
    Under the APA, we must “hold unlawful and set aside
    agency action, findings, and conclusions found to be . . .
    5
    Because the Commissioner does not contest the applicability of the
    APA or Chevron in this context, this case does not require us to decide the
    broader questions of the precise contours of the application of APA to the
    Commissioner’s administration of the tax system or the continued vitality
    of the theory of tax exceptionalism. See generally, e.g., Stephanie Hoffer
    and Christopher J. Walker, The Death of Tax Court Exceptionalism,
    99 MINN. L. REV. 221 (2014); Kristin E. Hickman, Coloring Outside the
    Lines: Examining Treasury’s (Lack of) Compliance with Administrative
    Procedure Act Rulemaking Requirements, 82 NOTRE DAME L. REV. 1727

    arbitrary, capricious, an abuse of discretion, or otherwise not
    in accordance with law,” “in excess of statutory jurisdiction,”
    or “without observance of procedure required by law.”
    
    5 U.S.C. § 706
    (2)(A), (C)–(D). However, “[t]he scope of
    review under the ‘arbitrary and capricious’ standard is narrow
    and a court is not to substitute its judgment for that of the
    agency.” State Farm, 
    463 U.S. at 43
    .
    If we conclude that Treasury complied with the APA in
    its rulemaking, we apply the familiar Chevron standard in
    examining the agency’s interpretation of the statute that
    defines the scope of its authority. Chevron, 
    467 U.S. at 843
    .
    A
    Accordingly, our first task is to determine whether
    Treasury complied with the APA in the first instance. Only
    if Treasury complied with the APA may we defer to its
    interpretation of § 482 under Chevron. Encino Motorcars,
    LLC v. Navarro, 
    136 S.Ct. 2117
    , 2125 (2016).6
    6
    We note that the procedural posture of this case—following
    enforcement— differs from that of a typical case challenging a regulation
    under the APA. Generally, strict APA-based challenges arise in the pre-
    enforcement context, which is less disruptive to the agency and which
    allows plaintiffs to avoid the six-year statute of limitations applicable to
    APA-based challenges. See 
    28 U.S.C. § 2401
    . By contrast, post-
    enforcement challenges, often brought after the six-year statute of
    limitations, are rarely brought under the APA, even if the APA proves
    relevant. Rather, courts are generally called on to address the degree of
    deference to which the agency is entitled. In these typical post-
    enforcement challenges, the ultimate question is not whether the agency
    action was procedurally defective but rather whether it was a permissible
    exercise of executive authority. The court focuses not on the APA but on
    the statute as it is implemented by the agency.
    ALTERA CORP. V. CIR                        27
    The APA “sets forth the full extent of judicial authority to
    review executive agency action for procedural correctness
    . . . .” FCC v. Fox Television Stations, Inc., 
    556 U.S. 502
    ,
    513 (2009). It “prescribes a three-step procedure for so-

    , 1203 (2015)
    (citing

    ). First, a “[g]eneral notice of proposed
    rule making” must ordinarily be published in the Federal

    5 U.S.C. § 553
    (b). Second, provided that “notice
    [is] required,” the agency must “give interested persons an
    opportunity to participate in the rule making through
    submission of written data, views, or arguments . . . .”
    § 553(c). “ An agency must consider and respond to
    significant comments received during the period for public
    comment.” Perez, 
    135 S.Ct. at 1203
    . Third, the agency must
    incorporate in the final rule “a concise general statement of
    [its] basis and purpose.” § 553(c).
    1
    Altera does not dispute that Treasury satisfied the first
    step by giving notice of the 2003 regulations. Altera, 14 T.C.
    at 103. Nor does there appear to be a controversy as to
    whether Treasury included in the final rule “a concise general
    statement of [its] basis and purpose.” 
    5 U.S.C. § 553
    .
    Rather, Altera argues that the regulations fail on the second
    step, asserting that although Treasury solicited public
    comments, it did not adequately consider and respond to
    those responses, rendering the regulations arbitrary and
    capricious under State Farm. Altera, 14 T.C. at 120–31. We
    disagree.
    Section 706 of the APA directs courts to “decide all
    relevant questions of law, interpret constitutional and
    28                  ALTERA CORP. V. CIR
    statutory provisions, and determine the meaning or
    applicability of the terms of an agency action.” 
    5 U.S.C. § 706
     (flush language). Agencies may not act in ways that
    are “arbitrary, capricious, an abuse of discretion, or otherwise
    not in accordance with law.” 
    5 U.S.C. § 706
    (2)(A).
    Following State Farm, the touchstone of arbitrary and
    capricious review under the APA is “reasoned
    decisionmaking.” State Farm, 
    463 U.S. at 52
    . “[T]he agency
    must examine the relevant data and articulate a satisfactory
    explanation for its action including a ‘rational connection
    between the facts found and the choice made.’” 
    Id. at 43
    (quoting Burlington Truck Lines v. United States, 
    371 U.S. 156

    135 S. Ct. at 2706
     (quoting State Farm, 
    463 U.S. at 43
    ).
    However, courts may not set aside agency action simply
    because the rulemaking process could have been improved;
    rather, we must determine whether the agency’s “path may
    reasonably be discerned.” State Farm, 
    463 U.S. at 43

    Altera argues that Treasury’s rulemaking process does not
    sufficiently support the regulations, which Altera understands
    to be a significant departure from Treasury’s earlier
    regulations implementing § 482. This argument is premised
    on: (1) Treasury’s rejection of the comments submitted in
    opposition to the proposed rule, and (2) Altera’s claim that
    Treasury’s current litigation position is inconsistent with
    statements made during the rulemaking process.
    “[A]n agency need only respond to ‘significant’
    comments, i.e., those which raise relevant points and which,
    if adopted, would require a change in the agency’s proposed
    ALTERA CORP. V. CIR                      29
    rule.” Am. Mining Congress v. EPA, 
    965 F.2d 759
    , 771 (9th
    Cir. 1992) (quoting Home Box Office v. FCC, 
    567 F.2d 9
    , 35
    & n.58 (D.C. Cir. 1977)). If the comments to which the
    agency did not respond would not bear on the agency’s
    “consideration of the relevant factors,” the court may not
    reverse the agency’s decision.

    Treasury published its notice of proposed rulemaking in
    2002. Compensatory Stock Options Under Section 482
    (Proposed), 
    67 Fed. Reg. 48,997
    . In its notice, Treasury
    made clear that it was relying on the commensurate with
    income provision. 
    Id. at 48,998
    . To support its position,
    Treasury drew from the legislative history of the 1986
    amendment, explaining that Congress intended a party to a
    QCSA to “bear its portion of all research and development
    costs.” 
    Id.
     (quoting H.R. CONF. REP. NO. 99-841, at II-638).
    It also informed interested parties of its intent to coordinate
    the new regulations with the arm’s length standard,
    suggesting that it was attempting to synthesize the potentially
    disparate standards found within § 482 itself. Id.; at 48,998,
    49,000–01.
    Commenters responded by attacking the proposed
    regulations as inconsistent with the traditional arm’s length
    standard. To support their position, they primarily discussed
    arm’s length agreements in which unrelated parties did not
    mention employee stock options. They explained that
    unrelated parties do not share stock compensation costs
    because it is difficult to value stock-based compensation, and
    there can be a great deal of expense and risk involved.
    In the preamble to the final rule, Treasury dismissed the
    comments (and, relatedly, the behavior of controlled
    taxpayers) as irrelevant:
    30              ALTERA CORP. V. CIR
    Treasury and the IRS continue to believe
    that requiring stock-based compensation to be
    taken into account for purposes of QCSAs is
    consistent with the legislative intent
    underlying section 482 and with the arm’s
    length standard (and therefore with the
    obligations of the United States under its
    income tax treaties . . .). The legislative
    history of the Tax Reform Act of 1986
    expressed Congress’s intent to respect cost
    sharing arrangements as consistent with the
    commensurate with income standard, and
    therefore consistent with the arm’s length
    standard, if and to the extent that the
    participants’ shares of income “reasonably
    reflect the actual economic activity
    undertaken by each.” See H.R. CONF. REP.
    NO. 99-481, at II-638 (1986). . . . [I]n order
    for a QCSA to reach an arm’s length result
    consistent with legislative intent, the QCSA
    must reflect all relevant costs, including such
    critical elements of cost as the cost of
    compensating employees for providing
    services related to the development of the
    intangibles pursuant to the QCSA. Treasury
    and the IRS do not believe that there is any
    basis for distinguishing between stock-based
    compensation and other forms of
    compensation in this context.
    Treasury and the IRS do not agree with
    the comments that assert that taking stock-
    based compensation into account in the QCSA
    context would be inconsistent with the arm’s
    ALTERA CORP. V. CIR                      31
    length standard in the absence of evidence
    that parties at arm’s length take stock-based
    compensation into account in similar
    circumstances. . . . The uncontrolled
    transactions cited by commentators do not
    share enough characteristics of QCSAs
    involving the development of high-profit
    intangibles to establish that parties at arm’s
    length would not take stock options into
    account in the context of an arrangement
    similar to a QCSA. . . .

    Final Rule),

    Treasury added:
    Treasury and the IRS believe that if a
    significant element of [the costs shared by
    unrelated parties] consists of stock-based
    compensation, the party committing
    employees to the arrangement generally
    would not agree to do so on terms that ignore
    the stock-based compensation.
    
    Id. at 51,173
    .
    With its references to legislative history, Treasury
    communicated its understanding that Congress had called
    upon it to move away from the traditional arm’s length
    standard.
    In short, the objectors were arguing that the evidence they
    cited—showing that unrelated parties do not share employee
    32                  ALTERA CORP. V. CIR
    stock compensation costs—proved that Treasury’s
    commensurate with income analysis did not comport with the
    arm’s length standard. Thus, the thrust of the objection was
    that Treasury misinterpreted § 482. But that is a separate
    question—one properly addressed in the Chevron analysis.
    That commenters disagreed with Treasury’s interpretation of
    the law does not make the rulemaking process defective.
    Under the APA, the issue is whether Treasury’s
    references to legislative history gave interested parties notice
    of its proposal and an opportunity to respond to it. Here,
    Treasury’s “path may reasonably be discerned.” State Farm,
    
    463 U.S. at 43
    . Treasury’s citations to legislative history in
    the notice of proposed rulemaking and the preamble to the
    final rule make clear enough why Treasury believed it could
    require related parties to share all costs—including employee
    stock compensation—in proportion to the income enjoyed by
    each. Treasury set forth its understanding that it should not
    examine comparable transactions when they do not in fact
    exist and should instead focus on a fair and reasonable
    allocation of costs and income. Compensatory Stock Options
    Under Section 482 (Proposed), 67 Fed. Reg. at 48,998
    (quoting H.R. Conf. Rep. No. 99-841, at II-638); accord
    Compensatory Stock Options under Section 482 (Preamble to
    Final Rule), 68 Fed. Reg. at 51,172. Treasury relied on
    Congressional rejection of primacy of the traditional arm’s
    length standard. None of the comments at issue address why
    Treasury was mistaken in its understanding that it was
    authorized to use a method that did not include comparables.
    Thus, Treasury’s refusal to credit oppositional comments
    is not fatal to a holding that it complied with the APA.
    Treasury gave sufficient notice of what it intended to do and
    why; it considered the comments, but it rejected them.
    ALTERA CORP. V. CIR                      33
    Because the comments had no bearing on “relevant factors”
    to the rulemaking, nor any bearing on the final rule, there was
    no APA violation. Am. Mining Congress, 
    965 F.2d at 771
    .
    Further, Treasury’s current litigation position is not
    inconsistent with the statements it made to support the 2003
    regulations at the time of the rulemaking. Altera argues that
    its position is justified by SEC v. Chenery Corp., 
    332 U.S. 194
     (1947). “[A] reviewing court . . . must judge the
    propriety of [agency] action solely by the grounds invoked by
    the agency.” Chenery, 
    332 U.S. at 196
    . “If those grounds are
    inadequate or improper, the court is powerless to affirm the
    administrative action by substituting what it considers to be
    a more adequate or proper basis.” 
    Id.
    Altera argues that the Commissioner cannot now claim
    that “Treasury reasonably determined that it was statutorily
    authorized to dispense with comparability analysis” because
    “[n]owhere in the regulatory history did the Secretary suggest
    that he ‘was statutorily authorized to dispense with
    comparability analysis.’” This argument twists Chenery,
    which protects judicial deference by strengthening
    administrative processes, into excessive proceduralism. See
    Nat’l Elec. Mfrs. Ass’n v. U.S. Dept. of Energy, 
    654 F.3d 496
    ,
    515 (4th Cir. 2011) (“[Chenery] does not oblige the agency to
    provide exhaustive, contemporaneous legal arguments to
    preemptively defend its action.”). But it is also inconsistent
    with the record, given Treasury’s citation to legislative
    history.
    2
    Altera also argues that Treasury did not adequately
    support its position that employee stock compensation is a
    34                  ALTERA CORP. V. CIR
    cost. Treasury cites generally to “tax and other accounting
    principles” for its determination that there is a “cost
    associated with stock-based compensation.” Compensatory
    Stock Options Under Section 482 (Proposed), 67 Fed. Reg. at
    48,999. Treasury classifies stock compensation as a “critical
    element” of R&D costs and notes that it is “clearly related to
    the intangible development area.” Compensatory Stock
    Options under Section 482 (Preamble to Final Rule), 68 Fed.
    Reg. at 51,173.
    The rulemaking record is sufficient to survive an APA
    challenge because Treasury’s position is supported by logic
    and by industry norms. Treasury wrote that parties would not
    “ignore” stock-based compensation if such compensation
    were a “significant element” of the compensation costs one
    party incurs and another party agrees to reimburse. Id. at
    51,173. Treasury’s determination is reasonable because
    parties dealing at arm’s length certainly would not grant stock
    options to each other’s employees without mentioning the
    arrangement in the cost-sharing agreement. In other words,
    parties dealing at arm’s length simply do not share these
    costs, but related parties, whose stock is commonly owned,
    do. “[T]hrough bargaining,” each unrelated party ensures that
    the cost-sharing agreement is in its best interest, meaning that
    the parties will consider the internal costs of stock
    compensation without requiring the other party to recognize
    those costs. Id.
    A distinction exists between the economic costs of stock
    compensation—which are debatable—and the accounting
    costs—which are not. Because entities account for the cost
    of providing employee stock options, it is reasonable for
    Treasury to allocate the costs, and it is irrelevant how much
    the same entity ultimately pays to provide the options.
    ALTERA CORP. V. CIR                      35
    Further, as the Commissioner noted, “tax and other
    accounting principles” provide a strong foundation for the
    Commissioner’s interpretation.
    Most notably, the Tax Code classifies stock-based
    compensation as a trade or business “expense.” 
    26 U.S.C. § 162
    (a). And the challenged regulation cites to the provision
    providing that the expense is deductible. 
    Treas. Reg. § 1.482
    -
    7A(d)(2)(iii)(A) (citing 
    26 U.S.C. § 83
    (h)) (“[T]he operating
    expense attributable to stock-based compensation is equal to
    the amount allowable . . . as a deduction for Federal income
    tax purposes . . . (for example, under 83(h)) . . . .”). Indeed,
    the dispute here is not truly whether stock-based
    compensation is a cost but whether Altera— rather than the
    Commissioner—may decide how to apportion that cost
    between related entities.
    3
    Finally, in addition to its general State Farm argument,
    Altera asks for a more searching review under FCC v. Fox
    Television Stations, Inc., 
    556 U.S. 502
    . Altera claims that the
    cost-sharing amendments present a major shift in
    administrative policy such that Treasury could not issue the
    regulations without carefully considering and broadcasting its
    decision. Altera argues that “[t]he assertion that the
    commensurate with income clause supplants the arm’s-length
    standard with a ‘purely internal’ analysis is a sharp—but
    unacknowledged— reversal from Treasury’s long-standing
    prior policy.” Red Br. 47.
    “Agencies are free to change their existing policies as
    long as they provide a reasoned explanation for the change.”
    Encino Motorcars, 136 S.Ct. at 2125. Indeed, “[w]hen an
    36                 ALTERA CORP. V. CIR
    agency changes its existing position, it ‘need not always
    provide a more detailed justification than what would suffice
    for a new policy created on a blank slate.’” Id. at 2125–26
    (quoting Fox, 
    556 U.S. at 515
    ). However, an agency may not
    “depart from a prior policy sub silentio or simply disregard
    rules that are still on the books.” Fox, 
    556 U.S. at 515
    .
    [A] policy change complies with the APA if
    the agency:
    (1) displays “awareness that it is changing
    position,”
    (2) shows that “the new policy is permissible
    under the statute,”
    (3) “believes” the new policy is better, and
    (4) provides “good reasons” for the new
    policy, which, if the “new policy rests upon
    factual findings that contradict those which
    underlay its prior policy,” must include “a
    reasoned explanation . . . for disregarding
    facts and circumstances that underlay or were
    engendered by the prior policy.”
    Organized Vill. of Kake v. USDA, 
    795 F.3d 956
    , 966 (9th Cir.
    2015) (en banc) (ellipses in original) (quoting Fox, 
    556 U.S. at
    515–16).
    This argument is not meaningfully different from Altera’s
    general APA argument. If the arm’s length standard allows
    the Commissioner to allocate costs between related parties
    without a comparability analysis, there is no policy change,
    ALTERA CORP. V. CIR                    37
    merely a clarification of the same policy. Moreover, even if
    the policy changed, it changed well before 2003, as Xilinx
    demonstrates. And if so, it changed as a result of the 1986
    amendment to § 482, in which case the question is, again,
    whether the cost-sharing regulations are allowable under
    Chevron.
    4
    Thus, the 2003 regulations are not arbitrary and
    capricious under the standard of review imposed by the APA.
    Treasury’s regulatory path may be reasonably discerned.
    Treasury understood § 482 to authorize it to employ a purely
    internal, commensurate with income approach in dealing with
    related companies. It provided adequate notice of its intent
    and adequately considered the objections. Its conclusion that
    stock based compensation should be treated as a cost was
    adequately supported in the record, and its position did not
    represent a policy change under Fox.
    B
    Having determined that Treasury adequately satisfied the
    State Farm requirements, we turn to Chevron.
    1
    Under Chevron, we first apply the traditional rules of
    statutory construction to determine whether “Congress has
    directly spoken to the precise question at issue.” Chevron,
    
    467 U.S. at 842
    . We start with the plain statutory words, and
    “when deciding whether the language is plain, we must read
    the words ‘in their context and with a view to their place in
    the overall statutory scheme.’” King v. Burwell, __ U.S. __,
    38                  ALTERA CORP. V. CIR
    __, 
    135 S. Ct. 2480
    , 2489 (2015) (quoting FDA v. Brown &
    Williamson Tobacco Corp., 
    529 U.S. 120
    , 133 (2000)). In
    addition, we examine the legislative history, the statutory
    structure, and “other traditional aids of statutory
    interpretation” in order to ascertain congressional intent.
    Middlesex Cty. Sewerage Auth. v. Nat’l Sea Clammers Ass’n,
    
    453 U.S. 1
    , 13 (1981). If, after conducting that Chevron step
    one examination, we conclude that the statute is silent or
    ambiguous on the issue, we then defer to the agency’s
    interpretation so long as “it is based on a permissible
    construction of the statute.” Chevron, 
    467 U.S. at 843
    . A
    permissible construction is one that is not “arbitrary,
    capricious, or manifestly contrary to the statute.” 
    Id. at 844
    .
    Ultimately, questions of deference boil down to whether
    “it appears that Congress delegated authority to the agency
    generally to make rules carrying the force of law, and that the
    agency interpretation claiming deference was promulgated in
    the exercise of that authority.” United States v. Mead Corp.,
    
    533 U.S. 218
    , 226–27 (2001). “When Congress has
    ‘explicitly left a gap for an agency to fill, there is an express
    delegation of authority to the agency to elucidate a specific
    provision of the statute by regulation,’ and any ensuing
    regulation is binding in the courts unless procedurally
    defective, arbitrary or capricious in substance, or manifestly
    contrary to the statute.” 
    Id. at 227
     (internal citation and
    footnote omitted) (quoting Chevron, 
    467 U.S. at
    843–44).
    Here, the resolution of our step one Chevron examination
    is straightforward. Section 482 does not speak directly to
    whether the Commissioner may require parties to a QCSA to
    share employee stock compensation costs in order to receive
    the tax benefits associated with entering into a QCSA.
    Further, as the text of the statute and its legislative history
    ALTERA CORP. V. CIR                      39
    indicate, Congress intended to provide Treasury with the
    flexibility it needed to prevent improper cost and income
    allocation between related parties for the purpose of defeating
    tax liability.
    Thus, we must move on to Chevron step two to consider
    whether Treasury’s interpretation of § 482 as to allocation of
    employee stock option costs is permissible. An agency’s
    interpretation of statutory authority is examined “in light of
    the statute’s text, structure and purpose.” Miguel-Miguel v.
    Gonzales, 
    500 F.3d 941
    , 949 (9th Cir. 2007). The
    interpretation fails if it is “unmoored from the purposes and
    concerns” of the underlying statutory regime. Judulang,
    565 U.S. at 64. Thus, Congress’s purpose in enacting and
    amending § 482 in 1986 is key to resolution of this issue.
    That purpose is parity. First Sec. Bank of Utah, 
    405 U.S. at 400
    . The 1986 amendment reflected Congress’s recognition
    that the traditional arm’s length standard did not serve the
    purpose of § 482.
    The 1986 amendment to § 482 provides that: “In the case
    of any transfer (or license) of intangible property . . . , the
    income with respect to such transfer or license shall be
    commensurate with the income attributable to the intangible.”
    This is a purely internal standard, and evidence supports
    Treasury’s belief that Congress intended it to be. H.R. REP.
    NO. 99-426, at 423–35; H.R. CONF. REP. NO. 99-841, at II-
    637. Indeed, Congress’s objective in amending § 482 was to
    ensure that income follows economic activity. H.R. CONF.
    REP. No. 99-841, at II-637. Further, legislative history
    supports Treasury’s application of the commensurate with
    income standard in the QCSA context. Congress did not
    want to interfere with controlled cost-sharing arrangements,
    but only to the degree that the allocation of costs and income
    40                  ALTERA CORP. V. CIR
    “reasonably reflect[s] the actual economic activity undertaken
    by each.” H.R. CONF. REP. No. 99-841, at II-638. Treasury’s
    decision to dispense with a comparability analysis was
    reasonable.
    So was Treasury’s determination that uncontrolled cost-
    sharing arrangements do not provide helpful guidance
    regarding allocations of employee stock compensation. As
    discussed above, Treasury discounted the relevance of
    comments demonstrating that parties at arm’s length do not
    share employee stock compensation costs, writing: “The
    uncontrolled transactions cited by commentators do not share
    enough characteristics of QCSAs involving the development
    of high-profit intangibles to establish that parties at arm’s
    length would not take stock options into account in the
    context of an arrangement similar to a QCSA.”
    Compensatory Stock Options under Section 482 (Preamble to
    Final Rule), 68 Fed. Reg. at 51,173.
    Treasury’s conclusion is entirely consistent with
    Congress’s rationale for amending § 482 in the first place.
    See id. (citing H.R. REP. NO. 99-426, at 423–25) (“As
    recognized in the legislative history of the Tax Reform Act of
    1986, there is little if any, public data regarding transactions
    involving high-profit intangibles.”); see also H.R. REP. NO.
    99-426, at 425 (“There are extreme difficulties in determining
    whether the arm’s length transfers between unrelated parties
    are comparable. . . . [I]t is appropriate to require that the
    payment made on a transfer of intangibles to a related foreign
    corporation be commensurate with the income attributable to
    the intangible.”).7
    7
    Although the 2017 amendment to § 482 has no bearing on our
    opinion, we note that Congress has not changed its mind:
    ALTERA CORP. V. CIR                             41
    As Congress noted, the goal of parity is not served by a
    constant search for comparable transactions. H.R. REP. NO.
    99-426, at 423. That is why, in 1986, it acted by adding the
    commensurate with income standard to § 482, synthesizing
    the long-standing arm’s length standard with the new
    provision; without an internal approach to allocation, related
    parties had been able to escape paying the taxes that would be
    paid by parties dealing at arm’s length. In other words, the
    amendment was intended to hone the definition of the arm’s
    length standard so that it could work to achieve arm’s length
    results instead of forcing application of arm’s length methods.
    The transfer pricing rules of section 482 and the
    accompanying Treasury regulations are intended to
    preserve the U.S. tax base by ensuring that taxpayers do
    not shift income properly attributable to the United
    States to a related foreign company through pricing that
    does not reflect an arm’s length result. . . . The arm’s
    length standard is difficult to administer in situations in
    which no unrelated party market prices exist for
    transactions between related parties.
    ...
    For income from intangible property, section 482
    provides ‘in the case of any transfer (or license) of
    intangible property (within the meaning of section 936
    (h)(3)(B)), the income with respect to such transfer or
    license shall be commensurate with the income
    attributable to the intangible.’ By requiring inclusion in
    income of amounts commensurate with the intangible,
    Congress was responding to concerns regarding the
    effectiveness of the arm’s-length standard with respect
    to intangible property—including, in particular, high-
    profit-potential intangibles.
    H. REP. NO. 115-466, at 574–75 (2017).

    Thus, the 2003 regulations are not “arbitrary and
    capricious in substance.” Mayo Found., 
    562 U.S. at 53
    (quoting Household Credit Servs., Inc. v. Pfennig, 
    541 U.S. 232
    , 242 (2004)). Treasury reasonably understood § 482 as
    an authorization to require internal allocation methods in the
    QCSA context, provided that the costs and income allocated
    are proportionate to the economic activity of the related
    parties. Treasury’s interpretation is not “arbitrary, capricious,
    or manifestly contrary to the statute,” and it is therefore
    permissible under Chevron. 
    467 U.S. at 844
    .
    2
    Altera contends that the Commissioner misreads § 482
    and its history, arguing that the addition of the commensurate
    with income standard to § 482 did nothing to change the
    meaning and operation of the arm’s length standard. Altera
    supports its argument with a canon of construction:
    “Amendments by implication, like repeals by implication, are
    not favored.” United States v. Welden, 
    377 U.S. 95
    , 102 n.12
    (1964). The canon does not apply here. It operates to prevent
    courts from attributing unspoken motives to legislators, not
    to force courts to ignore legislative action. It is illogical to
    argue that an amendment does not change the meaning of the
    statute that is amended. Moreover, Altera’s conclusion, that
    the commensurate with income standard is one method of
    satisfying the arm’s length standard, is one with which the
    Commissioner agrees.
    Altera’s interpretation of the 1986 amendment would
    render the commensurate with income clause meaningless
    except in two circumstances: (1) to allow the Commissioner
    to periodically adjust prices initially assigned following a
    comparability analysis; and (2) to reflect a party’s
    ALTERA CORP. V. CIR                      43
    contribution of existing intangible property or “buy-in” to a
    cost-sharing arrangement. This narrow reading of § 482 is
    not supported by the text or history of the 1986 amendment.
    The Commissioner’s allocation of employee stock
    compensation costs between related parties is necessary for
    Treasury to fulfill its obligation under § 482. Congress did
    not intend to interfere with qualified cost-sharing
    arrangements when those arrangements provided for the
    allocation of income consistent with the commensurate with
    income provision. H.R. CONF. REP. NO. 99-841, at II-638.

    Altera makes much of the United States’s treaty
    obligations with other countries. However, there is no
    evidence that the unworkable empiricism for which Altera
    argues is also incorporated into our treaty obligations. As
    demonstrated by nearly a century of interpreting § 482 and its
    precursor, the arm’s length standard is aspirational, not
    descriptive. It reflects neither how related parties behave nor
    how they are taxed. Moreover, our most recent treaties
    incorporate not only the arm’s length standard, but also the
    2003 regulations. See, e.g., Technical Explanation of the US-
    Poland Tax Treaty, at 31 (Feb. 13, 2013) (“It is understood
    that the Code section 482 ‘commensurate with income’
    standard for determining appropriate transfer prices for
    intangibles operates consistently with the arm’s-length
    standard. The implementation of this standard in the
    regulations under Code section 482 is in accordance with the
    general principles of paragraph 1 of Article 9 of the
    Convention . . . .”).
    44                  ALTERA CORP. V. CIR
    The 1986 amendment focused specifically on intangibles,
    and it gives Treasury the ability to respond to rapid changes
    in the high tech industry. “The broad language of [§ 482]
    reflects an intentional effort to confer the flexibility necessary
    to forestall . . . obsolescence.” Massachusetts v. EPA,
    
    549 U.S. 497
    , 532 (2007). In the modern economy, employee
    stock options are integral to R&D arrangements. In fact, in
    Altera’s 2015 annual report, its stock-based compensation
    cost equaled nearly five percent of total revenue. Altera
    Corp., Annual Report for the Fiscal Year Ended Dec. 31,
    2014 (Form 10-K). Simply speaking, the rise in employee
    stock compensation is an economic development that
    Treasury cannot ignore without rejecting its obligations under
    § 482.
    4
    Altera also argues that the outcome of this case is
    controlled by our Court’s decision in Xilinx. We disagree.
    While the Xilinx panel could have reached a holding that
    would foreclose the Commissioner’s current position, it did
    not.
    In Xilinx, this Court considered the 1994 and 1995 cost-
    sharing regulations. The case involved a matter of regulatory
    interpretation, not executive authority. Xilinx, Inc., another
    maker of programmable logic devices, challenged the
    Commissioner’s allocation of employee stock options
    between Xilinx and its Irish subsidiary. 
    598 F.3d at 1192
    . As
    framed by the panel, the issue was whether § 1.482-1
    (1994)—which sets forth the arm’s length standard—could be
    reconciled with § 1.482-7(d)(1) (1995)—under which parties
    to a QCSA were required to share “all . . . costs” incurred in
    developing intangibles. Id. at 1195.
    ALTERA CORP. V. CIR                      45
    Initially the panel, in a 2–1 decision, voted to reverse the
    Tax Court, which had unanimously struck the 1995 cost-
    sharing regulations. Xilinx, Inc. v. Comm’r, 
    567 F.3d 482
    (9th Cir. 2009), withdrawn 
    592 F.3d 1017
     (9th Cir. 2010).
    However, the panel withdrew its first opinion after
    reconsideration, and the panel—over Judge Reinhardt’s
    dissent—ultimately affirmed the Tax Court in striking the
    regulations. Xilinx, 
    598 F.3d 1191
    . As framed by all three
    judges in both the withdrawn and final opinions, the issue
    came down to whether the arm’s length standard and all costs
    provision could be synthesized. All three judges determined
    that synthesis was impossible, and the conflict was therefore
    whether the arm’s length standard, versus the all costs
    provision, had priority .
    Xilinx does not control for two reasons. First, the parties
    in Xilinx were not debating administrative authority, and the
    Court did not consider the “commensurate with income”
    standard, which Congress itself did not see as inconsistent
    with the arm’s length standard. Second, and more
    significantly, the Xilinx panel was faced with a conflict
    between two rules.         If the rules were conceptually
    distinguishable, they were also in direct conflict. The arm’s
    length rule, § 1.482-1(b)(1) (1994), listed specific methods
    for calculating an arm’s length result. The all costs provision
    was not one of those methods, as the first Xilinx majority
    noted. 
    567 F.3d at 491
    . Treasury issued the coordinating
    amendment in 2003, after the tax years at issue in Xilinx, and
    the arm’s length regulation now expressly references the cost-
    sharing provision that Altera challenges. The Xilinx panel did
    not address the “open question” of whether the 2003
    regulations remedied the error identified in that decision.
    
    598 F.3d at
    1198 n.4 (Fisher, J., concurring). Today, there is
    46                 ALTERA CORP. V. CIR
    no conflict in the regulations, and Altera does not challenge
    the regulations on the ground that a conflict exists.
    V
    In sum, we conclude that the Commissioner did not
    exceed the authority delegated to him by Congress. The
    Commissioner’s rule-making complied with the APA, and its
    regulation is entitled to Chevron deference.
    REVERSED.
    O’MALLEY, Circuit Judge, dissenting:
    A “foundational principle of administrative law [is] that
    a court may uphold agency action only on the grounds that
    the agency invoked when it took the action.” Michigan v.

    , 87 (1943)). In promulgating
    the rule we consider here, Treasury repeatedly insisted that it
    was applying the traditional arm’s length standard and that
    the resulting rule was consistent with that standard. Today,
    however, the majority holds that Treasury’s citation to the
    legislative history surrounding the enactment of the Tax
    Reform Act of 1986 “communicated its understanding that
    Congress had called upon it to move away from the historical
    arm’s length standard.” Op. 31. And the majority finds that,
    despite Treasury’s own statements to the contrary, that same
    citation to legislative history sufficed to “make it clear
    enough” to interested parties that Treasury was changing its
    longstanding practice of applying the arm’s length standard
    in all but the narrowest of circumstances. Op. 32.

    332 U.S. 194
    , 196 (1947)). It also
    endorses a practice of requiring interested parties to engage
    in a scavenger hunt to understand an agency’s rulemaking
    proposals. That is inconsistent with another fundamental
    Administrative Procedure Act (“APA”) principle: that a
    notice of proposed rulemaking “should be sufficiently
    descriptive of the ‘subjects and issues involved’ so that
    interested parties may offer informed criticism and
    comments.” Am. Mining Cong. v. U.S. EPA,

    the majority stretches “highly deferential” review, Providence
    Yakima Med. Ctr. v. Sebelius, 
    611 F.3d 1181
    , 1190 (9th Cir.

    473 F.3d 1043
    ,
    1051 (9th Cir. 2007)), beyond its breaking point.
    I instead would find, as the Tax Court did, that Treasury’s
    explanation of its rule did not satisfy the State Farm standard;
    that Treasury did not provide adequate notice of its intent to
    change its longstanding practice of employing the arm’s
    length standard; and that its new rule is invalid as arbitrary
    and capricious. I would also hold that this court’s previous
    decision in Xilinx, Inc. v. Commissioner of Internal Revenue
    (Xilinx II), 
    598 F.3d 1191
     (9th Cir. 2010), controls and
    mandates an order affirming the Tax Court’s decision. I
    therefore would affirm the judgment of the Tax Court that
    expenses related to stock-based compensation are not among
    the costs to be shared in qualified cost sharing arrangements
    (“QCSAs”) under 
    Treas. Reg. § 1.482-7
    (d)(1) (as amended in
    48                     ALTERA CORP. V. CIR
    2013). See Altera Corp. v. Comm’r, 
    145 T.C. 91
    , 92 (2015).
    For these reasons, I respectfully dissent.
    I. BACKGROUND
    A. The Arm’s Length Standard
    “The purpose of section 482 is to place a controlled
    taxpayer on a tax parity with an uncontrolled taxpayer by
    determining, according to the standard of an uncontrolled
    taxpayer, the true taxable income from the property and
    business of a controlled taxpayer.” Comm’r v. First Sec.
    Bank of Utah, 
    405 U.S. 394
    , 400 (1972) (quoting 
    Treas. Reg. § 1.482-1
    (b)(1) (1971)). The “touchstone” of this tax parity
    inquiry is the arm’s length standard. Xilinx II, 
    598 F.3d at
    1198 n.1 (Fisher, J., concurring). Since the 1930s, Treasury
    regulations consistently have explained that, “[i]n
    determining the true taxable income of a controlled taxpayer,
    the standard to be applied in every case is that of a taxpayer
    dealing at arm’s length with an uncontrolled taxpayer.”
    
    Treas. Reg. § 1.482-1
    (b)(1) (2003). That is, income and
    deductions are to be allocated among related companies in the
    same way that unrelated companies negotiating at arm’s
    length would allocate the same income and deductions.
    The 1986 amendment that introduced the commensurate
    with income standard did not dislodge the arm’s length test.1
    1
    This amendment added a second sentence to § 482 that provided:
    “In the case of any transfer (or license) of intangible property . . . , the
    income with respect to such transfer or license shall be commensurate
    with the income attributable to the intangible.” Tax Reform Act of 1986,
    Pub. L. No. 99-514, § 1231(e)(1), 
    100 Stat. 2085
    , 2562 (codified as
    amended at 
    26 U.S.C. § 482
    ).
    ALTERA CORP. V. CIR                      49
    Congress explained in the committee report that it was
    introducing the commensurate with income standard to
    address a “recurrent problem” with transfers of highly
    valuable intangible property: “the absence of comparable
    arm’s length transactions between unrelated parties, and the
    inconsistent results of attempting to impose an arm’s length
    concept in the absence of comparables.” H.R. REP. NO. 99-
    426, at 423–24 (1985). Congress noted that “[i]ndustry
    norms for transfers to unrelated parties of less profitable
    intangibles frequently are not realistic comparables in these
    cases,” and that “[t]here are extreme difficulties in
    determining whether the arm’s length transfers between
    unrelated parties are comparable.” 
    Id.
     at 424–25. To address
    this potential gap, Congress found it “appropriate to require
    that the payment made on a transfer of intangibles to a related
    foreign corporation . . . be commensurate with the income
    attributable to the intangible.” 
    Id. at 425
    .
    Treasury reiterated in its 1988 “White Paper” that
    “intangible income must be allocated on the basis of
    comparable transactions if comparables exist.” A Study of
    Intercompany Pricing under Section 482 of the Code (“White
    Paper”), I.R.S. Notice 88-123, 1988-
    2 C.B. 458
    , 474; see also
    
    id. at 473
     (noting that, where “there is a true comparable for”
    the licensing of a “high profit potential intangible[],” the
    royalty rate for the license “must be set on the basis of the
    comparable because that remains the best measure of how
    third parties would allocate intangible income”). Only “in
    situations in which comparables do not exist” would the
    commensurate with income standard apply. 
    Id. at 474
    .
    Indeed, the United States continued to insist in tax treaties,
    and in documents that Treasury issued to explain these
    treaties, that § 482 reflected the arm’s length principle. See
    Xilinx, 
    598 F.3d at
    1196–97 (citing tax treaty explanations);
    50                    ALTERA CORP. V. CIR
    see also 
    id.
     at 1198 n.1 (Fisher, J., concurring) (noting that
    “the 1997 United States-Ireland Tax Treaty, . . . and others
    like it, reinforce the arm’s length standard as Congress’
    intended touchstone for § 482”).2
    B. Treatment of Stock-Based Compensation
    Treasury promulgated new regulations governing the tax
    treatment of controlled transactions in 1994 and 1995. These
    regulations affirmed that “the standard to be applied in every
    case” was the arm’s length standard. 
    Treas. Reg. § 1.482
    -
    1(b)(1) (as amended in 1994). They also provided that
    intangible development costs included “all of the costs
    incurred by . . . [an uncontrolled] participant related to the
    intangible development area.” 
    Treas. Reg. § 1.482-7
    (d)(1)
    (as amended in 1995). The IRS interpreted this latter “all
    costs” provision to include stock-based compensation, so that
    related companies in cost-sharing agreements would have to
    share the costs of providing such compensation. Xilinx II,
    
    598 F.3d at
    1193–94.
    When Xilinx, Inc. (“Xilinx”) challenged the IRS’s
    interpretation, the Tax Court decided that the agency’s
    reading violated 
    Treas. Reg. § 1.482-1
    , because the IRS had
    not adduced evidence sufficient to show that unrelated parties
    transacting at arm’s length would share expenses related to
    2
    As the majority observes, more recent tax treaty explanations have
    also cited the alternative commensurate with income standard. Op. 42–43
    (citing Technical Explanation of the US-Poland Tax Treaty, at 31 (Feb.
    13, 2013)). Even these explanations, however, emphasize the primacy of
    the arm’s length standard, and they assure the reader that the
    commensurate with income standard “operates consistently with the
    arm’s-length standard.” Technical Explanation of the US-Poland Tax
    Treaty, at 30–31 (Feb. 13, 2013).

    stock-based compensation. Xilinx v. Commissioner (Xilinx I),
    
    125 T.C. 37
    , 53 (2005). The Commissioner did not appeal
    this underlying factual finding and, instead, argued on appeal
    to this court that 
    Treas. Reg. § 1.482-7
     superseded the arm’s
    length requirement of 
    Treas. Reg. § 1.482-1
    . All three
    members of the divided panel therefore assumed that sharing
    expenses related to stock-based compensation would be
    inconsistent with the arm’s length standard. Xilinx II, 
    598 F.3d at 1194
     (“The Commissioner does not dispute the tax
    court’s factual finding that unrelated parties would not share
    [employee stock options] as a cost.”); 
    id. at 1199
     (Reinhardt,
    J., dissenting) (assuming that the Tax Court “correctly
    resolved” the issue of whether sharing stock-based
    compensation costs would constitute an arm’s length result).
    We also assumed that 
    Treas. Reg. § 1.482-7
     required stock-
    based compensation expenses to be shared. 
    Id. at 1196
    (majority opinion) (noting that the “all costs” provision “does
    not permit any exceptions, even for costs that unrelated
    parties would not share”); 
    id. at 1199
     (Reinhardt, J.,
    dissenting) (assuming that the “all costs” provision includes
    “employee stock option costs”). But a majority of the panel
    ultimately held that the arm’s length standard, which was the
    fundamental “purpose” of the regulations, trumped 
    Treas. Reg. § 1.482-7
    , and therefore that stock-based compensation
    expenses could not be shared in the absence of evidence that
    unrelated parties would share such costs. 
    Id. at 1196
    (majority opinion); see also 
    id.
     at 1198 n.1 (Fisher, J.,
    concurring) (finding “the arm’s length standard” to be
    “Congress’ intended touchstone for § 482”). On that ground,
    we affirmed the Tax Court’s judgment in favor of Xilinx. Id.
    at 1196 (majority opinion).

    C. The Regulations at Issue
    While Xilinx II was pending before this court, Treasury
    promulgated the regulations at issue here. Compensatory
    Stock Options Under Section 482, 
    68 Fed. Reg. 51,171
    ,
    51,172 (Aug. 26, 2003) (codified at 26 C.F.R. pts. 1 and 602).
    The amended regulations sought to reconcile the apparent
    contradiction between the arm’s length standard in 
    Treas. Reg. § 1.482-1
     and the requirement that stock-based
    compensation expenses be shared under 
    Treas. Reg. § 1.482
    -
    7. The former provision now specifies that § 1.482-7
    “provides the specific method to be used to evaluate whether
    a [QCSA] produces results consistent with an arm’s length
    result.” 
    Treas. Reg. § 1.482-1
    (b)(2)(i) (2003). And § 1.482-
    7, in turn, now provides that a QCSA produces an arm’s
    length result “if, and only if,” the participants share all of the
    costs of intangible development—explicitly including costs
    associated with stock-based compensation—in proportion to
    their shares of reasonably anticipated benefits attributable to
    such development. 
    Treas. Reg. § 1.482-7
    (d)(2) (2003).
    Altera Corp. (“Altera U.S.”), a Delaware corporation, and
    its subsidiary Altera International, a Cayman Islands
    corporation, (collectively, “Altera”) entered into several cost-
    sharing agreements in 1997, under which Altera U.S. licensed
    various forms of intangible property to Altera International,
    and Altera International paid royalties to Altera U.S. Altera,
    
    145 T.C. at
    92–93. During the 2004 to 2007 taxable years,
    Altera U.S. granted stock options and other stock-based
    compensation to certain of its employees, but costs related to
    that compensation were not included in the cost pool under
    the operative cost-sharing agreements. 
    Id. at 93
    .
    ALTERA CORP. V. CIR                      53
    Each year from 2004 to 2007, the IRS notified Altera that
    the cost-sharing payments did not satisfy the new regulations.
    
    Id. at 94
    . But when Altera challenged these regulations, the
    Tax Court unanimously held, as discussed in more detail
    below, that the explanation Treasury offered in the preamble
    accompanying the new regulations was insufficient to justify
    those regulations under State Farm. 
    Id.
     at 120–33. The
    Commissioner appeals that decision.
    II. Discussion
    The Tax Court considered and rejected Treasury’s stated
    explanation for its regulation—that Treasury applied the
    commensurate with income test because it could find no
    transactions comparable to the QCSAs at issue, and that
    Treasury’s analysis was actually consistent with the arm’s
    length standard. But the Commissioner now argues on
    appeal, and the majority accepts, that what Treasury was
    actually saying is that § 482 no longer requires an arm’s
    length analysis. I disagree.
    A. The New Rule Is Invalid Under State Farm
    Under the Administrative Procedure Act, we must “hold
    unlawful and set aside agency action . . . found to be . . .
    arbitrary, capricious, an abuse of discretion, or otherwise not
    in accordance with law.” 
    5 U.S.C. § 706
    (2). To satisfy this
    standard, “the agency must examine the relevant data and
    articulate a satisfactory explanation for its action including a
    ‘rational connection between the facts found and the choice
    made.’” State Farm, 
    463 U.S. at 43
     (quoting Burlington
    Truck Lines v. United States, 
    371 U.S. 156
    , 168 (1962)).
    “That is, an agency must ‘cogently explain why it has
    exercised its discretion in a given manner,’ and ‘[i]n
    54                  ALTERA CORP. V. CIR
    reviewing that explanation, we must “consider whether the
    decision was based on a consideration of the relevant factors
    and whether there has been a clear error of judgment.”’” Nw.
    Envtl. Def. Ctr. v. Bonneville Power Admin., 
    477 F.3d 668
    ,
    687 (9th Cir. 2007) (alteration in original) (quoting State
    Farm, 
    463 U.S. at 43, 48
    ).
    Although an agency action is not subject to “more
    searching review” simply because it represents a change in
    position, “the requirement that an agency provide reasoned
    explanation for its action would ordinarily demand that it
    display awareness that it is changing position.” FCC v. Fox

    I start, therefore, with what Treasury said when it
    promulgated the regulation at issue. In Treasury’s notice of
    proposed rulemaking, the agency explained the origins of the
    commensurate with income standard and discussed the White
    Paper. Compensatory Stock Options Under Section 482,
    
    67 Fed. Reg. 48,997
    , 48,998 (proposed July 29, 2002) (to be
    codified at 26 C.F.R. pt. 1). Treasury noted, in particular, the
    White Paper’s observation “that Congress intended that
    Treasury and the IRS apply and interpret the commensurate
    with income standard consistently with the arm’s length
    standard.” 
    Id.
     (citing White Paper, 1988-2 C.B. at 458, 477).
    Treasury then detailed how the proposed rules would
    function, including that the new rules required stock-based
    compensation costs to be included among the costs shared in
    a QCSA to produce “results consistent with an arm’s length
    result.” Id. at 49,000–01.
    Treasury expanded on its reasoning in the preamble to the
    final rule. It explained that the tax treatment of stock-based
    compensation in QCSAs would have to be consistent “with
    the arm’s length standard (and therefore with the obligations
    of the United States under its income tax treaties and with the
    OECD transfer pricing guidelines).” Compensatory Stock
    Options Under Section 482, 68 Fed. Reg. at 51,172. Treasury
    observed, however, that the legislative history of the 1986
    amendment to § 482 “expressed Congress’s intent to respect
    cost sharing arrangements as consistent with the
    commensurate with income standard, and therefore consistent
    56                 ALTERA CORP. V. CIR
    with the arm’s length standard, if and to the extent that
    participants’ shares of income ‘reasonably reflect the actual
    economic activity undertaken by each.’” Id. (quoting H.R.
    Conf. Rep. No. 99-481, at II-638 (1986)). Applying this
    standard, Treasury declared that, “in order for a QCSA to
    reach an arm’s length result consistent with legislative
    intent,” the QCSA must include stock-based compensation
    among the costs shared. Id.
    Throughout the preamble, Treasury repeatedly
    emphasized that it was applying the arm’s length standard.
    Treasury explained, for example, that “[t]he regulations
    relating to QCSAs have as their focus reaching results
    consistent with what parties at arm’s length generally would
    do if they entered into cost sharing arrangements for the
    development of high-profit intangibles.” Id. (emphasis
    added). Treasury determined that “[p]arties dealing at arm’s
    length in [a cost-sharing] arrangement based on the sharing
    of costs and benefits generally would not distinguish between
    stock-based compensation and other forms of compensation.”
    Id. (emphasis added). And Treasury concluded that “[t]he
    final regulations provide that stock-based compensation must
    be taken into account in the context of QCSAs because such
    a result is consistent with the arm’s length standard.” Id.
    (emphasis added).
    Treasury also responded to comments invoking the arm’s
    length standard. See id. (rejecting “comments that assert that
    taking stock-based compensation into account in the QCSA
    context would be inconsistent with the arm’s length standard
    in the absence of evidence that parties at arm’s length take
    stock-based compensation into account in similar
    circumstances”). Treasury acknowledged that comparable
    arm’s-length transactions may have been relevant, but it
    ALTERA CORP. V. CIR                       57
    determined that there were no comparable transactions
    available for QCSAs for the development of high-profit
    intangibles:
    While the results actually realized in similar
    transactions under similar circumstances
    ordinarily provide significant evidence in
    determining whether a controlled transaction
    meets the arm’s length standard, in the case of
    QCSAs such data may not be available. As
    recognized in the legislative history of the Tax
    Reform Act of 1986, there is little, if any,
    public data regarding transactions involving
    high-profit intangibles. The uncontrolled
    transactions cited by commentators do not
    share enough characteristics of QCSAs
    involving the development of high-profit
    intangibles to establish that parties at arm’s
    length would not take stock options into
    account in the context of an arrangement
    similar to a QCSA.
    Id. at 51,172–73. Treasury further detailed why it believed
    that certain comparable transactions proposed by
    commentators were not in fact comparable. Id. at 51,173.
    The Tax Court held that Treasury’s explanation for its
    regulation was insufficient under State Farm. Altera,
    
    145 T.C. at
    120–33. It found that Treasury “failed to provide
    a reasoned basis” for its “belief that unrelated parties entering
    into QCSAs would generally share stock-based compensation
    costs.” 
    Id. at 123
    . The court acknowledged that agencies
    need not gather empirical evidence for some policy-based
    propositions, but it held that “the belief that unrelated parties
    58                 ALTERA CORP. V. CIR
    would share stock-based compensation costs in the context of
    a QCSA” was not such a proposition. 
    Id.
     In reaching this
    conclusion, the court observed that commentators submitted
    significant evidence about whether unrelated parties would
    share stock-based compensation costs in QCSAs; that the Tax
    Court itself had made a factual determination on that issue in
    Xilinx I; and that Treasury was required at least to attempt to
    gather empirical evidence before declaring that no such
    evidence was available. 
    Id.
     at 123–24.
    The Tax Court then detailed why Treasury’s explanation
    for the regulations was insufficient. The court noted that only
    some QCSAs involved high-profit intangibles or included
    stock-based compensation as a significant element of
    compensation, yet Treasury failed to distinguish between
    QCSAs with and without those characteristics. 
    Id.
     at 125–27.
    And the court found that Treasury responded only in
    conclusory fashion to a number of comments identifying
    comparable transactions or explaining why unrelated parties
    would not share stock-based compensation costs in QCSAs.
    
    Id.
     at 127–30. On these grounds, the Tax Court struck down
    the regulation. 
    Id.
     at 133–34.
    The Commissioner does not meaningfully dispute the Tax
    Court’s determination that Treasury’s analysis under the
    arm’s length standard was inadequate and unsupported. The
    Commissioner now contends, instead, “that, in the context of
    a QCSA, the arm’s-length standard does not require an
    analysis of what unrelated entities do under comparable
    circumstances.” Appellant’s Br. 57 (internal quotation marks
    omitted). In the Commissioner’s view, Treasury’s detailed
    explanations regarding its comparability analysis were merely
    “extraneous observations”—“since Treasury reasonably
    determined that it was statutorily authorized to dispense with
    ALTERA CORP. V. CIR                       59
    comparability analysis in this narrow context, there was no
    need for it to establish that the uncontrolled transactions cited
    by commentators were insufficiently comparable.”
    Appellant’s Br. 64.
    The majority accepts Treasury’s rationalization. “With its
    references to legislative history,” the majority holds, Treasury
    adequately “communicated its understanding that Congress
    had called upon it to move away from the historical arm’s
    length standard.” Op. 31. The majority finds that Treasury
    was therefore entitled to ignore the comments opposing the
    final rule because they did not “bear on the agency’s
    ‘consideration of the relevant factors.’” Op. 28–29 (quoting
    Am. Mining Congress v. EPA, 
    965 F.2d 759
    , 771 (9th Cir.
    1992)). As to Altera’s rejoinder that Treasury never
    suggested that it had the authority to “dispense with”
    comparability analysis entirely, Appellee’s Br. 43, the
    majority dismisses these arguments as “twist[ing] Chenery
    . . . into excessive proceduralism,” Op. 33.
    I do not share the majority’s view. Treasury may well
    have believed that, given the fundamental characteristics of
    stock-based compensation in QCSAs, it could dispense with
    arm’s length analysis entirely. Cf. Xilinx II, 
    598 F.3d at 1197
    (Fisher, J., concurring) (hypothesizing why unrelated
    companies may not share stock-based compensation costs).
    But the APA required Treasury to say that it was taking this
    position, which departed starkly from Treasury’s previous
    regulations. See Fox, 
    556 U.S. at 515
     (“[T]he requirement
    that an agency provide reasoned explanation for its action
    would ordinarily demand that it display awareness that it is
    changing position.”). As we held in Xilinx, the previous
    regulations preserved the primacy of the arm’s length
    standard and its requirement of comparability analysis. See
    60                  ALTERA CORP. V. CIR
    Xilinx II, 
    598 F.3d at
    1195–96 (explaining the then-operative
    version of 
    Treas. Reg. § 1.482-1
    ).
    In amending those regulations, however, Treasury never
    said—either in the notice of proposed rulemaking or in the
    preamble accompanying the final rule—that the nature of
    stock compensation in the QCSA context rendered arm’s
    length analysis irrelevant. Treasury instead explained only
    that it could not conduct an arm’s length analysis because
    comparable transactions could not be found.                See
    Compensatory Stock Options Under Section 482, 68 Fed.
    Reg. at 51,172–73 (“While the results actually realized in
    similar transactions under similar circumstances ordinarily
    provide significant evidence in determining whether a
    controlled transaction meets the arm’s length standard, in the
    case of QCSAs such data may not be available.”). As the
    majority acknowledges, in fact, “Treasury set forth its
    understanding that it should not examine comparable
    transactions when they do not in fact exist and should instead
    focus on a fair and reasonable allocation of costs and
    income.” Op. 32 (emphasis added).
    Treasury itself explained, in effect, that a precondition for
    the applicability of the commensurate with income standard
    is the lack of real-world comparable transactions with which
    to make an arm’s-length comparison. The comments
    submitted were relevant to the issue of whether “similar
    transactions under similar circumstances” existed. Any such
    transactions, as Treasury originally admitted, would
    “ordinarily provide significant evidence in determining
    whether a controlled transaction meets the arm’s length
    standard.” Compensatory Stock Options Under Section 482,
    ALTERA CORP. V. CIR                           61
    68 Fed. Reg. at 51,172.3 If Treasury felt that these comments
    were irrelevant, it presumably would have said so.
    Treasury’s decision to respond to the comments on their
    merits underscores that Treasury’s only justification for
    eschewing comparability analysis was its belief that no
    comparable transactions could be found. The fact that
    evidence of comparable transactions might support more
    favorable tax treatment does not mean such comparables do
    not exist.4
    The APA’s safeguards ensure that those regulated do not
    have to guess at the regulator’s reasoning; just as importantly,
    they afford regulated parties a meaningful opportunity to
    respond to that reasoning. Treasury’s notice of proposed
    rulemaking ran afoul of these safeguards by failing to put the
    relevant public on notice of its intention to depart from
    traditional arm’s length analysis. See CSX Transp., Inc. v.
    Surface Transp. Bd., 
    584 F.3d 1076
    , 1080 (D. C. Cir. 2009)
    (holding that a final rule “violates the APA’s notice
    requirement where ‘interested parties would have had to
    “divine [the agency’s] unspoken thoughts”’” (alteration in
    original) (quoting Int’l Union, United Mine Workers of Am.
    V. Mine Safety & Health Admin., 
    407 F.3d 1250
    , 1259–60
    3
    The majority points to no language in the notice of proposed
    rulemaking that contradicts this understanding.
    4
    The majority also glosses over the Tax Court’s criticism that the
    final rule applied to all QCSAs, but was based only on Treasury’s beliefs
    about the subset of QCSAs involving “high-profit intangibles” where
    stock-based compensation is a “significant element” of compensation.
    Altera, 
    145 T.C. at
    125–26 (quoting Compensatory Stock Options Under
    Section 482, 68 Fed. Reg. at 51,173). Treasury’s failure to explain this
    leap and the Commissioner’s failure to defend it provide another reason
    that the regulation does not satisfy the State Farm standard.
    62                 ALTERA CORP. V. CIR
    (D.C. Cir. 2005))). And asking Treasury to show its work in
    the preamble to its final rule—that is, to set forth when and
    why the agency believed that arm’s length analysis was not
    required—is not, as the majority suggests, “excessive
    proceduralism.” Op. 33. It is the essence of the review that
    State Farm demands.
    When the Tax Court conducted that review, it considered
    the explanation that Treasury offered, and it found that
    Treasury “failed to provide a reasoned basis” for its “belief
    that unrelated parties entering into QCSAs would generally
    share stock-based compensation costs.” Altera, 
    145 T.C. at 123
    . The Tax Court set forth in detail why Treasury’s
    explanation for the regulations was insufficient. 
    Id.
     at
    125–30. Treasury offers no response to these findings; it
    simply invites this court to recreate the record in order to
    justify its decisionmaking. I therefore would hold, as the Tax
    Court did, that the 2003 regulations are invalid under State
    Farm.
    B. Section 482 Does Not Require Sharing of Stock-Based
    Compensation Costs
    Because I would find the 2003 regulations were invalid,
    I believe that this court’s decision in Xilinx II controls, and
    that the Tax Court properly entered judgment in favor of
    Altera. Altera, 
    145 T.C. at 134
    . Even if Xilinx II did not
    control, I would hold that related parties in QCSAs need not
    share costs associated with stock-based compensation.
    “Chevron deference is not warranted where the regulation is
    ‘procedurally defective’—that is, where the agency errs by
    failing to follow the correct procedures in issuing the
    regulation.” Encino Motorcars, LLC v. Navarro, 
    136 S. Ct. 2117
    , 2125 (2016) (quoting United States v. Mead Corp.,
    ALTERA CORP. V. CIR                      63
    
    533 U.S. 218
    , 227 (2001)). I therefore would interpret the
    statute in the first instance, without deference.
    I agree with the majority that § 482 does not address this
    issue directly. Op. 38–39. But I agree with amicus curiae
    Cisco Systems, Inc. (“Cisco”), that, under the best reading of
    § 482, QCSAs are not subject to the commensurate with
    income standard. See generally Amicus Curiae Br.
    Supporting Appellee and Affirmance on Behalf of Cisco
    Systems, Inc. As Cisco points out, the commensurate with
    income standard applies only to a “transfer (or license) of
    intangible property,” 
    26 U.S.C. § 482
    , which is distinct from
    a cost sharing agreement for joint development of intangibles.
    See White Paper, 1988-2 C.B. at 474 (noting that “bona fide
    research and development cost sharing arrangements”
    provided a way to “avoid[] section 482 transfer pricing issues
    related to the licensing or other transfer of intangibles”).
    QCSAs fall neatly into the latter category. See 
    Treas. Reg. § 1.482-7
    (a)(1) (2003) (defining a QCSA as “an
    agreement under which the parties agree to share the costs of
    development of one or more intangibles in proportion to their
    shares of reasonably anticipated benefits”).               The
    Commissioner’s argument that the commensurate with
    income standard applies to “intangible transactions in
    general, and cost sharing arrangements in particular,”
    Appellant’s Br. 57, is inconsistent with the plain language of
    the statute. Under the only reasonable interpretation of § 482,
    therefore, the commensurate with income standard does not
    apply to QCSAs. For at least this reason, I also disagree with
    the majority’s conclusion that Treasury’s reading of § 482
    satisfies the second step of the Chevron test. Op. 39–46.
