This case turns on the meaning of the word “error” in a land use permit that the Forest Service issued to a ski resort owner. See 16 U.S.C. § 497. It raises a difficult question about the standard of review that a court should apply to the Forest Service’s own interpretation of such a document. Ultimately, we decide that, for reviewing purposes, we should treat the permit (called a “Term Special Use Permit”) as if it were a kind of contract between the Service and the resort owner. That is to say, we should allow the agency no more freedom to interpret the words of such a permit than were that permit a contract between a government agency and a private party. That being so, we conclude that the Forest Service incorrectly interpreted the word “error” in the Term Permit, and we reverse a district court judgment in its favor.

I

Background,

The background facts are fairly simple. In 1986 Meadow Green-Wildcat Corporation (“Meadow Green”) bought the assets of Wildcat Mountain Corporation (“Wildcat”), a ski resort operated on federal land at Pinkham Notch, New Hampshire. In October 1986 the Forest Service issued Meadow Green a new Term Special Use Permit, allowing it to use this federally owned land for twenty years in return for a fee. See Appendix A. The Term Permit contained detailed rules for calculating that fee. The Term Permit said that, among other things, the Service would calculate the fee on the basis of Meadow Green’s investment in the ski area assets, which the Permit stated was $5,049,853. The Permit’s fee calculation rules call that investment “Gross Fixed Assets” or “GFA.” The Term Permit also said, however, that the Service could recalculate the fee and apply the new fee retroactively if this $5,049,853 “GFA” figure was an “error.” To be specific, the Term Permit stated the following:

As of April 30, 1986, the initial GFA under this ownership has been determined to be $5,049,853 as shown in detail on attached schedule, [sic] 1, “Gross Fixed Assets.” If an error is found in the GFA amount, it shall be changed to the correct amount retroactive to the date the error occurred.

(Emphasis added.)

In 1989 Forest Service auditors announced they had found an “error” in the GFA amount. They said it should have been $3,195,911. The Service then recalculated the fee for 1986, 1987, and 1988. And, it asked Meadow Green to pay approximately $65,000 in additional fees for those years.

After exhausting its agency appeals, Meadow Green asked the federal district court to review, and to set aside, this agency determination. See 5 U.S.C. § 701 et seq. It said the Service was wrong about the “error,” for there was no error, and, in any event, the court should estop the agency from denying the $5 million figure. The district court granted summary judgment for the Service, and Meadow Green has appealed. In our view, the $5 million figure is not “an error” within the meaning of those words as used in the Permit. Consequently, the Service’s determination was “not in accordance with law” and must be set aside. 5 U.S.C. § 706(2)(A). Therefore, we need not reach the question of agency estoppel.

II

The Standard of Review

A Forest Service regulation that defines a “Term Permit,” the kind of permit now before us, says that such a Permit is “compensable according to its terms.” 36 C.F.R. § 251.51. The words “an error” are terms of the present Permit. Thus, the Service’s revised fee is correct, and lawful, if the $5 million figure was “an error,” but not otherwise. In deciding the meaning of the term “an error,” however, are we to defer to the agency’s interpretation of those words? In other words, are we to treat the Term Permit as if it were an agency regulation, or a statute in which Congress has delegated interpretive power to the administering body? See, e.g., Chevron v. Natural Resources Defense Council, Inc., 467 U.S. 837, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984) (courts should defer to reasonable agency interpretations of statutes); Udall v. Tollman, 380 U.S. 1, 4, 85 S.Ct. 792, 795, 13 L.Ed.2d 616 (1965) (courts should give controlling weight to reasonable agency interpretations of regulations). Or, should we treat the Permit like a contract that the government might make with a private party, giving less weight to the agency’s interpretation of the document’s language, the meaning of which raises a “question of law?” See, e.g., Halifax Engineering, Inc. v. United States, 915 F.2d 689, 690 (Fed.Cir.1990); Shea and Schaengold, A Guide to the Court of Appeals for the Federal Circuit, Briefing Papers (December 1990) at 5 (“It is well established that the interpretation of a contract is a matter of law that may be freely decided by the Federal Circuit.”).

We believe that for several reasons we should treat the Term Permit document rather like a contract for reviewing purposes. First, the Permit document itself reads like a contract. It provides long-term authority to use land in return for the permittee’s payment of a rental fee. It is twenty-two pages long and contains a highly detailed set of terms and conditions. It uses contract-like language, such as “this permit may be revoked upon breach of any of the conditions herein.” Both the Forest Supervisor and the permittee have signed the document, the latter placing his signature under the statement that he “agree[s]” that he “accepts and will abide by” the document’s “terms and conditions.” We think that the expectation of a person signing such a document is that its terms would bind both him and the Service. Although the terms of the document give the Service power to change various conditions, such as rental conditions, for the future, or even to revoke the Permit on 30 days notice, nothing in the document, or regulations, or authorizing statute suggests that the Service is to have some special advantage, not shared by the permittee, in interpreting the meaning of the document’s terms. Indeed, it would seem surprising and unfair if the terms of this document, without so stating, bind the permittee but leave the other party (the Service) free to interpret those same terms as it wishes (limited only by the bounds of “reasonableness”).

Second, the statutes that authorize the Forest Service to issue Term Permits state that their purpose is to allow the construction and operation of “hotels, resorts, and other [recreational] structures,” 16 U.S.C. § 497, all facilities that “are ... likely to require long-term financing.” 16 U.S.C. § 497b. These phrases suggest that one function of the permit is to offer a permit-tee the security needed to raise many millions of dollars in investment. It is difficult to reconcile the Service’s desire for “deference” to its interpretation of the Permit with this purpose. We do not see how a document, the terms of which one party remains comparatively free to interpret to its own advantage, can provide the other party (and its financial backers) the security, stability, or assurance a large and long-term investment would seem to require.

Third, the Service’s official regulations treat the Term Permit as if it were a kind of contract. As we have previously said, the regulations state that the Permit is “compensable according to its terms.” 36 C.F.R. § 251.51. Moreover, these regulations define a Term Permit very much as they define a “lease,” an instrument the terms of which bind the parties. The first is defined as “a special use authorization to occupy and use ... land ... for a specified period which is both revocable and compen-sable according to its terms.” The second is defined as a special use authorization which conveys a right of occupancy and use of ... land ... for a specified period and purpose and is both revocable and com-pensable according to its terms.” Id. Moreover, the regulations say that a per-mittee may “sublet the use and occupancy of the premises.” 36 C.F.R. § 251.55(a). Further, these regulations reserve for the government specific rights, such as “continuing right of access,” id. § 251.55(b)(1), thereby suggesting that the permit grants other definite rights to the permittee. These regulations reiterate and elaborate upon the statutory expectation that a ski area permittee will make “existing on site investment” of considerable “magnitude,” and that the “magnitude of planned facilities ... [will] require long-term financing and/or operation.” 36 C.F.R. § 251.56(b)(2)(E). Although the regulations also state that the Government is free to “revoke” or “terminate” the Permit in the manner and for the reasons specified by the Permit, a contract that one party may terminate for specified reasons is no less a contract. See Farnsworth, Contracts § 2.14 at 77-78 (1982). And unless and until it is terminated, its terms govern actions taken by both parties.

Fourth, the authority that the Government cites for the contrary proposition offers it no real support. The Government cites Chevron, supra, which instructs the courts to pay particular attention to an agency’s interpretation of its governing statute, at least when courts can infer (from language and circumstances) that Congress, in enacting the statute, intended the courts to do so. Chevron does not dictate a reviewing court’s attitude towards the language of a contract, or of a document that resembles a contract, particularly under circumstances where too much court “deference” would seem to work at cross-purposes with Congress’s likely statutory intent. Other similar cases, such as Udall v. Tallman, 380 U.S. 1, 85 S.Ct. 792, require a reviewing court to give controlling weight to an agency’s reasonable interpretation of its own regulations. Id. at 4, 85 S.Ct. at 795. Such cases reflect the common sense intuition that an agency is more likely than a court to know what its own regulations mean, as well as the legal inference that Congress, delegating authority to an agency to promulgate such regulations, likely intended a degree of “deference.” However, neither the language nor the reasoning of those cases suggests they require similar deference to the agency’s interpretation of a contract that it makes with an outside, party, or, for the same reasons, to a Permit that bears all the earmarks of a contract.

The government also refers to language in an unreported district court case quoted in a Court of Claims case called Mountain States Telephone and Telegraph Co. v. United States, 204 Ct.Cl. 521, 499 F.2d 611 (1974) which says, “[a] special use permit is not a lease.” Id., 499 F.2d at 615-16. This language is dicta, for Mountain States involved interpretation of the language of a regulation, not a permit. But, in any event, the language is beside the point, for the issue here is not whether the “special use permit” (which may or may not have been the same kind of “term permit” here at issue) is a “lease.” The issue is whether a court reviewing an agency’s interpretation of the language in such a permit should or should not treat it like a contract, a matter on which neither Mountain States, nor the district court case, sheds any light.

In sum, we find no strict instruction in the law that a reviewing court must give an agency great (legislative or regulatory) “leeway” or “deference” whenever it interprets the meaning of words on any piece of paper emanating from that agency. Rather, the degree of leeway or deference due depends upon many different factors, including the function that the paper serves, viewed in light of governing statutes and regulations. In this instance the statute, the regulations, and the form and function of the paper itself all suggest that we exercise a degree of independent judgment in interpreting its language. Thus, without holding that the Permit “is” a contract, or that courts should always consider it as such, we shall treat it like a contract for purposes of deciding how much weight to give the interpretation one party (here the agency) offers for one of its nontechnical terms. See, e.g., Halifax Eng’g, Inc., 915 F.2d at 690.

Ill

The Meaning of “Error"

For purposes of this case, we shall assume that the Permit’s words “error ... in the GFA amount” (the words that allow a retroactive fee adjustment) include such mechanical and fact-related matters as arithmetical mistakes, mistakes in calculation, misreporting of asset values, and the like. We are also willing to assume (but purely for argument’s sake) that they include a Service officer’s failure to follow a clear instruction in the publicly available Forest Service Manual, a Manual that (among many other things) explains to the public and to the Service officers themselves just how the officers should go about calculating the Permit’s GFA figure. See 36 C.F.R. § 216.2(a) (Manual includes “general instruction and direction needed on a continuous basis by Forest Service officers at more than one unit ...”). We believe, however, that those words do not include retroactive revisions to a figure that reflects an officer’s reasonable interpretation of an ambiguous Manual instruction which the Service later decides to interpret differently. And, without including this kind of interpretive error within the scope of the Permit’s words “an error,” the Service cannot prevail here (for the reasons explained in Part IV, infra).

We interpret the word “error” in the contract to exclude such retroactively corrected errors in judgment for several reasons. First, the Permit itself suggests that the kind of “error” in question is mathematical, arithmetical, fact-related, and the like, for it uses the word just after a sentence that says that the GFA “has been determined to be $5,049,853 as shown in detail on attached schedule, 1,” which identifies the cost of various assets. It goes on to say, “If an error is found in the GFA amount” it may be corrected retroactively. It uses the word “error” again, three pages later, when it says,

All fee calculations and records of sales and GFA are subject to period audit. Errors in calculation or payment will be corrected as needed for conformance with those audits.

Since the word “error” appears in the context of detailed, listed amounts, references to “calculation or payment” and “audits,” this suggests it covers errors in stating, or calculating, figures, not judgmental errors, or errors of interpretation.

Second, the Forest Service itself has repeatedly held that the word “error” means an error in arithmetic and not an error in judgment. In January 1986, for example, in a case involving Snowbird Ski area, the Chief of the Forest Service wrote that “only those changes relating primarily to errors [in] ... arithmetic can reasonably be interpreted as subject to unilateral correction.” In 1989, in a case involving Winter Park Ski Area, the Associate Deputy Chief of the Forest Service wrote, “we find the language is not clear that the intent was to provide for correction of errors of judgment.” We would not say that the Service is bound by these informal interpretations. See Quinonez-Lopez v. Coco Lagoon Development Corp., 733 F.2d 1, 4 (1st Cir.1984). But, we believe that a reviewing court is free to consult such publicly available, comparable agency interpretations of the Permit’s language, as it consults an agency’s published opinions, to see if the agency is acting consistently. Cf. Exxon Corp. v. Department of Energy, 91 F.R.D. 26, 41-42 (N.D.Tex.1981) (permitting discovery of contemporaneous agency interpretations of ambiguous regulations); Apex Construction Co. v. United States, 719 F.Supp. 1144, 1147 n. 1 (D.Mass.1989) (“Other possible grounds for obtaining discovery beyond the administrative record include ... discovery of the agency’s ‘contemporaneous construction’ of a particular term or regulation where the meaning is vague or ambiguous or where construction used in the particular case appears inconsistent.”). And, where it is not, the court may pay somewhat less attention to its position.

Finally, a different interpretation of the word “error” — an interpretation that would allow the agency to count as “an error” a judgmental miscalculation as to how the agency would later interpret an ambiguous instruction — would give the agency unusually broad powers to assess fees retroactively, to change its interpretations in surprising ways, and to use those changes to increase fees previously assessed for land uses that have long since occurred. And, it seems unlikely the parties would have agreed to such an arrangement.

In saying this, we emphasize the difference between retroactive and prospective adjustment in fees. The Permit clearly gives the Service the right to make prospective changes to the rental fee. Indeed, a Forest Service regulation requires each “ski area authorization” to

include a clause that provides that the Forest Service may adjust and calculate future rental fees

to reflect various factors. 36 C.F.R. § 251.57(h) (emphasis added); cf. 36 C.F.R. § 251.57(f) (providing for “rental fee adjustment whenever necessary ... as a result of fee review,” but providing that “revised fees will take effect at the beginning of the next payment year”) (emphasis added). But, a prospective change is very different from a retroactive change. It is easy, for example, to imagine the Automobile Registry raising license fees for next year, perhaps even for this year; but, it would be most unusual for such an agency to raise the license fee for a year that has passed and send drivers a bill for a retroactive surcharge. Thus, we have considered language in the Permit that says, for example, that

GFA will be established by and changed at the sole discretion of the Forest Service based on the current interpretation of guidelines

as referring to prospective changes, as specified in the regulations just mentioned. And, for similar reasons, we shall not interpret the “error” clause, which authorizes retroactive change, broadly. That is to say, we do not believe a private party would normally agree that the Forest Service has broad authority to raise rates after the event. And, we therefore should not stretch a contract’s language to say the party did agree to such a condition when that is not what the language says.

IV

The “Judgmental” Error

Given our understanding of the meaning of the words “an error” in the Permit, the Service cannot win this case. That is because Meadow Green is right— the $5,049,853 GFA figure reflected no error at all, or, if there was an error, it consisted of an error in interpreting ambiguous Manual instructions, that is a judgmental error of the kind that we have just said falls outside the scope of the word “error” in the Permit. We reach this conclusion because, after reading the instructions in the Manual with care, we find them unclear on the relevant point, and we do not see how any reasonable person could conclude the contrary.

To understand why this is so, the reader must first understand the Service’s basic system for calculating permit fees (called the Graduated Rate Fee System or “GRFS”), as set forth in the Forest Service Manual. That system is designed to impose a “graduated fee,” on a ski resort’s sales, a fee that increases as does the profitability of a ski resort. To accomplish this result, the GRFS calculates a “break even” point, a point at which sales are large enough to cover most of the resort’s variable costs (i.e., costs other than “fixed” costs). It charges a low percentage fee on “less than break-even” sales, a higher percentage fee on sales between the “break even point” and twice the “break even point,” and a still higher percentage fee on further sales. Thus, if, for example, a ski resort’s “break even” point were $200,000 in sales, the Service’s fee might amount to 1 percent of sales up to $200,000; 3 percent of sales between $200,000 and $400,000; and 5 percent of sales above $400,000.

The Service calculates the “break even” point by a very rough-and-ready rule of thumb, which it apparently applies to all ski resorts whether or not cost conditions at an individual ski resort differ from the norm. (One possible explanation for this ad hoc measure of costs is that the fee is so low that individual cost variations are not likely to make enough difference to warrant the administrative effort needed to take them into account.) That rule first values the resort’s investment in fixed assets devoted to generating revenue from the activity in question (such as ski lifts, tows, and ski schools, in the case of ski revenues). The Manual defines this investment — the Gross Fixed Assets, or GFA — as

The total of the original undepreciated costs (not the present value) of the current permittee’s investment in improvements and fixtures plus the cost of equipment necessary to generate sales and other income.

Forest Service Manual § 2715.14c-3. The Manual then simply selects a ratio between sales and GFA (presumably on the basis of typical experience) which it calls the “break even point.” In the case of ski investment in lifts, tows and ski schools, for example, the Manual says that 20 percent is the “break even point,” which is to say that once sales reach 20 percent of GFA, the resort, according to the Manual, “breaks even.” If the resort’s original investment in lifts, tows and ski schools was $1 million, the resort reaches its “break even point” when its sales reach $200,000. As we have said, the resort would then pay 1 percent on sales below $200,000, 3 percent on sales between $200,000 and $400,000, and 5 percent on further sales. If the resort instead had invested only $250,000 in lifts, tows, and ski schools, it would pay 1 percent on sales below 20 percent of $250,000 (or $50,-000); 3 percent on sales between $50,000 and $100,000; and 5 percent on sales above $100,000.

With this structure in mind, there are two circumstances that favor the Service’s view that given the Manual’s instructions, the $5 million GFA figure in the Permit was an obvious “error.” First, the Manual says, in a section entitled “Determining Gross Fixed Assets,” that the GFA is based on the “permittee’s original investment.” Forest Service Manual § 2715.14c-3. It adds that the GFA “includes the original costs to the current permittee.” Id. The “permittee” (and certainly the “current permittee”) in this case is Meadow Green, not its predecessor Wildcat. Wildcat fell on hard times, and Meadow Green bought its assets cheaply. The parties agree that the $5 million dollar figure was Wildcat’s GFA; were Meadow Green’s GFA calculated afresh on the basis of the price it paid for Wildcat’s assets, the $3 million figure (we assume) would reflect that cost.

Second, the Manual gives fairly specific instructions and examples designed to tell the Forest Service Officer how to calculate GFA “Upon Sale and Transfer of a Permit.” In that situation the new owner’s investment in fixed assets will differ from the investment of the seller. The Manual says that the Service officer should then calculate what it would now cost to reproduce the physical assets that the new owner has bought. For purposes of making this calculation, the Manual provides a chart — a kind of cost-inflation-index — so that the Service officer need only apply a simple formula which converts the original cost of the assets into today’s dollars. (For example, if the prior owner’s ski lift, tow and ski school investment was $100,000, and the owner made the investment in 1920, the officer would apply this formula to arrive at a cost in today’s dollars of, say, $1 million, which would be the GFA.) The Manual calls this inflation-adjusted figure the “reconstruction cost.”

The Manual’s examples (which we have put in Appendix B) make clear that when the prior owner sells the resort at a price higher than the prior GFA, the new GFA is the lower of a) the new owner’s actual purchase price and b) the “reconstruction cost.” We think we understand why this is so. On the one hand, the Service does not want a new owner’s GFA to be more than he really paid for the resort; on the other hand, it does not want to allow the new owner’s GFA to reflect the prior owner’s “good will” rather than simply the cost of the physical assets. (Otherwise, a prior owner of a very profitable resort could sell out, capitalizing the value of future profits, and creating a new, high GFA — and a corresponding high break-even point — that would require application of the Service’s lowest percentage fee.) Regardless of the reasons behind these rules, we think these provisions are relatively clear.

The problem for the Service, however, consists of other provisions in the Manual that suggest that the Service officer may, or must, calculate the GFA differently when a prior owner sells to a new owner at a price significantly lower than the prior GFA. For one thing, the Manual is written in language that suggests the Service officer may have a degree of discretion in deciding just how to value the new owner’s GFA. It says, for example, that the Service “will normally recognize the purchaser of an existing concession as a new per-mittee,” Forest Service Manual § 2715.14c-4, thereby implying that the Service officer might, in special circumstances, not do so. More importantly, that section goes on to say that

GFA for the new permit which is established at the time the new permit is issued is either the (1) original construction cost, (2) original purchase cost, or (3) previously established GFA, each adjusted by the costs of construction over the years, plus costs of equipment, and fixtures to indicate the current cost of the plant; not the total business.

(Emphasis added). This language reinforces the notion of some discretionary authority in respect to GFA itself, for it seems to say that a Service officer might use the “previously established GFA” as the GFA for a new permittee. Two paragraphs later, when the Manual seems to impose a ceiling on a new permittee’s GFA, it says

such a [new permittee’s] GFA when developed and assigned, in the case of a sale and transfer will not exceed the purchase price or reconstruction cost.

This language does not say “purchase price or reconstruction cost whichever is lower.” Rather, it seems to leave the choice to the Service officer, or, at least, to the officer as guided by the examples that the Manual provides. Meadow Green asserts (without contradiction) that the $5 million GFA figure in its permit is no higher than the “reconstruction cost” (the historic cost as inflated by the Manual’s chart). Thus, as far as the Manual’s explicit language is concerned, it seems to authorize the Service officer to use the Permit’s $5 million figure.

As we mentioned above, the table of examples itself suggests that the new per-mittee’s “purchase price” sets a ceiling on GFA of “reconstruction cost or purchase price, whichever is lower.” But, those examples all involve a purchase price that is higher than the prior owner’s investment. The only example that deals with a purchase price below the prior owner’s investment illustrates the exact opposite result. In this example the prior owner’s GFA is carried over. The example says that the seller’s GFA was $100,000, that a “forced sale” realized $50,000 and that the buyer’s GFA is $100,000. And, the commentary describes the example as:

Mortgage was foreclosed and sold for $50,000. The full original cost not adjusted to the present date would be allowed.

Forest Service Manual § 2715.14c-7. We recognize that the Wildcat sale to Meadow Green was not an involuntary sale or a mortgage foreclosure and that the Service now says that the example is limited to those circumstances. Yet, one reading the example might reasonably conclude that it applies to many low priced sales, or at least to distress sales, sales brought about by poor business conditions and at a price significantly lower than prior investment.

A reader of the regulations and the examples, aware of the fee calculation’s basic theory, might have a particular reason for thinking the “low-price” example applied to many, if not all, low price sales. Recall the ski resort owner who invested $1 million in lifts, tows and ski schools. The fee calculation rules assume that his sales reach the “break even point,” at $200,000 (20 percent of GFA). Now suppose this owner, falling on hard times, sells the resort for $250,000. If the new owner’s GFA must fall to $250,-000, his “break even point” becomes $50,-000 in sales. But, is it likely that the variable (non-fixed) costs of operating lifts, tows, and ski schools at this same resort have fallen to only one-quarter of what they were before? Is it reasonable to think that this new owner will “break even” so much sooner than the prior owner (though, of course, his investment is considerably less)? The Manual’s system leads a reader to ask this kind of question, and the question itself could suggest a need for an exception to the “purchase price as GFA ceiling” rule, which the example in the Manual would seem naturally to supply.

We do not say the Manual’s instruction must be read this way. We recognize that the Service has the legal power to write its own instructions and to tell us (within reason) what those written instructions mean. Cf. Udall v. Tollman, 380 U.S. at 4, 85 S.Ct. at 795. But, that fact does not make these regulations clear or unambiguous. The Service cannot use administrative law words such as “leeway” and “deference” magically to transform mud into crystal or to characterize as transparent that which, in fact, is opaque.

The Manual’s instructions are not clear; they are ambiguous; the Service officer’s “error,” at most, was an error of interpretation, an “error” of judgment about the meaning of ambiguous instructions. And, for the reasons we have pointed out in Part III, supra, the Permit’s word “error” does not cover that kind of mistake. Consequently, the Service lacked the legal power to change the GFA retroactively and to assess, retroactively, an increased fee for the years 1986, 1987, and 1988. We need not consider Meadow Green's claim of es-toppel, for this reason is sufficient to demonstrate that the agency’s assessment was not “in accordance with law.” 5 U.S.C. § 706(2)(A). Its determination must, therefore, be set aside. The judgment of the district court is

Reversed.
