Justice Blackmun
delivered the opinion of the Court.
Over 35 years ago, in Crane v. Commissioner, 331 U. S. 1 (1947), this Court ruled that a taxpayer, who sold property encumbered by a nonrecourse mortgage (the amount of the [302]*302mortgage being less than the property’s value), must include the unpaid balance of the mortgage in the computation of the amount the taxpayer realized on the sale. The case now before us presents the question whether the same rule applies when the unpaid amount of the nonrecourse mortgage exceeds the fair market value of the property sold.

On August 1, 1970, respondent Clark Pelt, a builder, and his wholly owned corporation, respondent Clark, Inc., formed a general partnership. The purpose of the partnership was to construct a 120-unit apartment complex in Duncanville, Tex., a Dallas suburb. Neither Pelt nor Clark, Inc., made any capital contribution to the partnership. Six days later, the partnership entered into a mortgage loan agreement with the Farm & Home Savings Association (F&H). Under the agreement, F&H was committed for a $1,851,500 loan for the complex. In return, the partnership executed a note and a deed of trust in favor of F&H. The partnership obtained the loan on a nonrecourse basis: neither the partnership nor its partners assumed any personal liability for repayment of the loan. Pelt later admitted four friends and relatives, respondents Tufts, Steger, Stephens, and Austin, as general partners. None of them contributed capital upon entering the partnership.
The construction of the complex was completed in August 1971. During 1971, each partner made small capital contributions to the partnership; in 1972, however, only Pelt made a contribution. The total of the partners’ capital contributions was $44,212. In each tax year, all partners claimed as income tax deductions their allocable shares of ordinary losses and depreciation. The deductions taken by the' partners in 1971 and 1972 totalled $439,972. Due to these contributions and deductions, the partnership’s adjusted basis in the property in August 1972 was $1,455,740.
[303]*303In 1971 and 1972, major employers in the Duncanville area laid off significant numbers of workers. As a result, the partnership’s rental income was less than expected, and it was unable to make the payments due on the mortgage. Each partner, on August 28, 1972, sold his partnership interest to an unrelated third party, Fred Bayles. As consideration, Bayles agreed to reimburse each partner’s sale expenses up to $250; he also assumed the nonrecourse mortgage.
On the date of transfer, the fair market value of the property did not exceed $1,400,000. Each partner reported the sale on his federal income tax return and indicated that a partnership loss of $55,740 had been sustained.1 The Commissioner of Internal Revenue, on audit, determined that the sale resulted in a partnership capital gain of approximately $400,000. His theory was that the partnership had realized the full amount of the nonrecourse obligation.2
Relying on Millar v. Commissioner, 577 F. 2d 212, 215 (CA3), cert. denied, 439 U. S. 1046 (1978), the United States Tax Court, in an unreviewed decision, upheld the asserted deficiencies. 70 T. C. 756 (1978). The United States Court of Appeals for the Fifth Circuit reversed. 651 F. 2d 1058 (1981). That court expressly disagreed with the Millar analysis, and, in limiting Crane v. Commissioner, supra, to its facts, questioned the theoretical underpinnings of the Crane [304]*304decision. We granted certiorari to resolve the conflict. 456 U. S. 960 (1982).

Section 752(d) of the Internal Revenue Code of 1954, 26 U. S. C. § 752(d), specifically provides that liabilities involved in the sale or exchange of a partnership interest are to “be treated in the same manner as liabilities in connection with the sale or exchange of property not associated with partnerships.” Section 1001 governs the determination of gains and losses on the disposition of property. Under § 1001(a), the gain or loss from a sale or other disposition of property is defined as the difference between “the amount realized” on the disposition and the property's adjusted basis. Subsection (b) of §1001 defines “amount realized”: “The amount realized from the sale or other disposition of property shall be the sum of any money received plus the fair market value of the property (other than money) received.” At issue is the application of the latter provision to the disposition of property encumbered by a nonrecourse mortgage of an amount in excess of the property’s fair market value.

In Crane v. Commissioner, supra, this Court took the first and controlling step toward the resolution of this issue. Beulah B. Crane was the sole beneficiary under the will of her deceased husband. At his death in January 1932, he owned an apartment building that was then mortgaged for an amount which proved to be equal to its fair market value, as determined for federal estate tax purposes. The widow, of course, was not personally liable on the mortgage. She operated the building for nearly seven years, hoping to turn it into a profitable venture; during that period, she claimed income tax deductions for depreciation, property taxes, interest, and operating expenses, but did not make payments upon the mortgage principal. In computing her basis for the depreciation deductions, she included the full amount of the [305]*305mortgage debt. In November 1938, with her hopes unfulfilled and the mortgagee threatening foreclosure, Mrs. Crane sold the building. The purchaser took the property subject to the mortgage and paid Crane $3,000; of that amount, $500 went for the expenses of the sale.
Crane reported a gain of $2,500 on the transaction. She reasoned that her basis in the property was zero (despite her earlier depreciation deductions based on including the amount of the mortgage) and that the amount she realized from the sale was simply the cash she received. The Commissioner disputed this claim. He asserted that Crane’s basis in the property, under § 113(a)(5) of the Revenue Act of 1938, 52 Stat. 490 (the current version is § 1014 of the 1954 Code, as amended, 26 U. S. C. §1014 (1976 ed. and Supp. V)), was the property’s fair market value at the time of her husband’s death, adjusted for depreciation in the interim, and that the amount realized was the net cash received plus the amount of the outstanding mortgage assumed by the purchaser.
In upholding the Commissioner’s interpretation of § 113 (a)(5) of the 1938 Act,3 the Court observed that to regard merely the taxpayer’s equity in the property as her basis would lead to depreciation deductions less than the actual physical deterioration of the property, and would require the basis to be recomputed with each payment on the mortgage. 331 U. S., at 9-10. The Court rejected Crane’s claim that any loss due to depreciation belonged to the mortgagee. The effect of the Court’s ruling was that the taxpayer’s basis was the value of the property undiminished by the mortgage. Id., at 11.

Section 752(d) of the Internal Revenue Code of 1954, 26 U. S. C. § 752(d), specifically provides that liabilities involved in the sale or exchange of a partnership interest are to “be treated in the same manner as liabilities in connection with the sale or exchange of property not associated with partnerships.” Section 1001 governs the determination of gains and losses on the disposition of property.

A
In Crane v. Commissioner, supra, this Court took the first and controlling step toward the resolution of this issue. Beulah B. Crane was the sole beneficiary under the will of her deceased husband. At his death in January 1932, he owned an apartment building that was then mortgaged for an amount which proved to be equal to its fair market value, as determined for federal estate tax purposes. The widow, of course, was not personally liable on the mortgage. She operated the building for nearly seven years, hoping to turn it into a profitable venture; during that period, she claimed income tax deductions for depreciation, property taxes, interest, and operating expenses, but did not make payments upon the mortgage principal. In computing her basis for the depreciation deductions, she included the full amount of the [305]*305mortgage debt. In November 1938, with her hopes unfulfilled and the mortgagee threatening foreclosure, Mrs. Crane sold the building. The purchaser took the property subject to the mortgage and paid Crane $3,000; of that amount, $500 went for the expenses of the sale.
Crane reported a gain of $2,500 on the transaction. She reasoned that her basis in the property was zero (despite her earlier depreciation deductions based on including the amount of the mortgage) and that the amount she realized from the sale was simply the cash she received. The Commissioner disputed this claim. He asserted that Crane’s basis in the property, under § 113(a)(5) of the Revenue Act of 1938, 52 Stat. 490 (the current version is § 1014 of the 1954 Code, as amended, 26 U. S. C. §1014 (1976 ed. and Supp. V)), was the property’s fair market value at the time of her husband’s death, adjusted for depreciation in the interim, and that the amount realized was the net cash received plus the amount of the outstanding mortgage assumed by the purchaser.
In upholding the Commissioner’s interpretation of § 113 (a)(5) of the 1938 Act,3 the Court observed that to regard merely the taxpayer’s equity in the property as her basis would lead to depreciation deductions less than the actual physical deterioration of the property, and would require the basis to be recomputed with each payment on the mortgage. 331 U. S., at 9-10. The Court rejected Crane’s claim that any loss due to depreciation belonged to the mortgagee. The effect of the Court’s ruling was that the taxpayer’s basis was the value of the property undiminished by the mortgage. Id., at 11.
[306]*306The Court next proceeded to determine the amount realized under § 111(b) of the 1938 Act, 52 Stat. 484 (the current version is § 1001(b) of the 1954 Code, 26 U. S. C. § 1001(b)). In order to avoid the “absurdity,” see 331 U. S., at 13, of Crane’s realizing only $2,500 on the sale of property worth over a quarter of a million dollars, the Court treated the amount realized as it had treated basis, that is, by including the outstanding value of the mortgage. To do otherwise would have permitted Crane to recognize a tax loss unconnected with any actual economic loss. The Court refused to construe one section of the Revenue Act so as “to frustrate the Act as a whole.” Ibid.
Crane, however, insisted that the nonrecourse nature of the mortgage required different treatment. The Court, for two reasons, disagreed. First, excluding the nonrecourse debt from the amount realized would result in the same absurdity and frustration of the Code. Id., at 13-14. Second, the Court concluded that Crane obtained an economic benefit from the purchaser’s assumption of the mortgage identical to the benefit conferred by the cancellation of personal debt. Because the value of the property in that case exceeded the amount of the mortgage, it was in Crane’s economic interest to treat the mortgage as a personal obligation; only by so doing could she realize upon sale the appreciation in her equity represented by the $2,500 boot. The purchaser’s assumption of the liability thus resulted in a taxable economic benefit to her, just as if she had been given, in addition to the boot, a sum of cash sufficient to satisfy the mortgage.4
[307]*307In a footnote, pertinent to the present case, the Court observed:
“Obviously, if the value of the property is less than the amount of the mortgage, a mortgagor who is not personally liable cannot realize a benefit equal to the mortgage. Consequently, a different problem might be encountered where a mortgagor abandoned the property or transferred it subject to the mortgage without receiving boot. That is not this case.”' Id., at 14, n. 37.
B
This case presents that unresolved issue. We are disinclined to overrule Crane, and we conclude that the same rule applies when the unpaid amount of the nonrecourse mortgage exceeds the value of the property transferred. Crane ultimately does not rest on its limited theory of economic benefit; instead, we read Crane to have approved the Commissioner’s decision to treat a nonrecourse mortgage in this context as a true loan. This approval underlies Crane’s holdings that the amount of the nonrecourse liability is to be included in calculating both the basis and the amount realized on disposition. That the amount of the loan exceeds the fair market value of the property thus becomes irrelevant.
When a taxpayer receives a loan, he incurs an obligation to repay that loan at some future date. Because of this obligation, the loan proceeds do not qualify as income to the taxpayer. When he fulfills the obligation, the repayment of the loan likewise has no effect on his tax liability.
Another consequence to the taxpayer from this obligation occurs when the taxpayer applies the loan proceeds to the purchase price of property used to secure the loan. Because of the obligation to repay, the taxpayer is entitled to include the amount of the loan in computing his basis in the property; the loan, under § 1012, is part of the taxpayer’s cost of the [308]*308property. Although a different approach might have been taken with respect to a nonrecourse mortgage loan,5 the Commissioner has chosen to accord it the same treatment he gives to a recourse mortgage loan. The Court approved that choice in Crane, and the respondents do not challenge it here. The choice and its resultant benefits to the taxpayer are predicated on the assumption that the mortgage will be repaid in full.
When encumbered property is sold or otherwise disposed of and the purchaser assumes the mortgage, the associated [309]*309extinguishment of the mortgagor’s obligation to repay is accounted for in the computation of the amount realized.6 See United States v. Hendler, 303 U. S. 564, 566-567 (1938). Because no difference between recourse and nonrecourse obligations is recognized in calculating basis,7 Crane teaches that the Commissioner may ignore the nonrecourse nature of the obligation in determining the amount realized upon disposition of the encumbered property. He thus may include in the amount realized the amount of the nonrecourse mortgage assumed by the purchaser. The rationale for this treatment is that the original inclusion of the amount of the mortgage in basis rested on the assumption that the mortgagor incurred an obligation to repay. Moreover, this treatment balances the fact that the mortgagor originally received the proceeds of the nonrecourse loan tax-free on the same assumption. [310]*310Unless the outstanding amount of the mortgage is deemed to be realized, the mortgagor effectively will have received untaxed incomé at the time the loan was extended and will have received an unwarranted increase in the basis of his property.8 The Commissioner’s interpretation of § 1001(b) in this fashion cannot be said to be unreasonable.
C
The Commissioner in fact has applied this rule even when the fair market value of the property falls below the amount of the nonrecourse obligation. Treas. Reg. § 1.1001-2(b), 26 CFR § 1.1001 — 2(b) (1982);9 Rev. Rul. 76-111, 1976-1 Cum. Bull. 214. Because the theory on which the rule is based applies equally in this situation, see Millar v. Commissioner, 67 T. C. 656, 660 (1977), aff’d on this issue, 577 F. 2d 212, 215-216 (CA3), cert. denied, 439 U. S. 1046 (1978);10 Mendham Corp. v. Commissioner, 9 T. C. 320, 323-324 (1947); Lutz & Schramm Co. v. Commissioner, 1 T. C. 682, 688-689 (1943), we have no reason, after Crane, to question this treatment.11
[311]*311Respondents received a mortgage loan with the concomitant obligation to repay by the year 2012. The only difference between that mortgage and one on which the borrower [312]*312is personally liable is that the mortgagee’s remedy is limited to foreclosing on the securing property. This difference does not alter the nature of the obligation; its only effect is to shift from the borrower to the lender any potential loss caused by devaluation of the property.12 If the fair market value of the property falls below the amount of the outstanding obligation, the mortgagee’s ability to protect its interests is impaired, for the mortgagor is free to abandon the property to the mortgagee and be relieved of his obligation.
This, however, does not erase the fact that the mortgagor received the loan proceeds tax-free and included them in his basis on the understanding that he had an obligation to repay the full amount. See Woodsam Associates, Inc. v. Commissioner, 198 F. 2d 357, 359 (CA2 1952); Bittker, supra n. 7, at 284. When the obligation is canceled, the mortgagor is relieved of his responsibility to repay the sum he originally received and thus realizes value to that extent within the meaning of § 1001(b). From the mortgagor’s point of view, when his obligation is assumed by a third party who purchases the encumbered property, it is as if the mortgagor first had been paid with cash borrowed by the third party from the mortgagee on a nonrecourse basis, and then had used the cash to satisfy his obligation to the mortgagee.
Moreover, this approach avoids the absurdity the Court recognized in Crane. Because of the remedy accompanying the mortgage in the nonrecourse situation, the depreciation [313]*313in the fair market value of the property is relevant economically only to the mortgagee, who by lending on a nonrecourse basis remains at risk. To permit the taxpayer to limit his realization to the fair market value of the property would be to recognize a tax loss for which he has suffered no corresponding economic loss.13 Such a result would be to construe “one section of the Act ... so as ... to defeat the intention of another or to frustrate the Act as a whole.” 331 U. S., at 13.
In the specific circumstances of Crane, the economic benefit theory did support the Commissioner’s treatment of the nonrecourse mortgage as a personal obligation. The footnote in Crane acknowledged the limitations of that theory when applied to a different set of facts. Crane also stands for the broader proposition, however, that a nonrecourse loan should be treated as a true loan. We therefore hold that a taxpayer must account for the proceeds of obligations he has received tax-free and included in basis. Nothing in either § 1001(b) or in the Court’s prior decisions requires the Commissioner to permit a taxpayer to treat a sale of encumbered property asymmetrically, by including the proceeds of the nonrecourse obligation in basis but not accounting for the proceeds upon transfer of the encumbered property. See [314]*314Estate of Levine v. Commissioner, 634 F. 2d 12, 16 (CA2 1980).
Ill
Relying on the Code’s § 752(c), 26 U. S. C. § 752(c), however, respondents argue that Congress has provided for precisely this type of asymmetrical treatment in the sale or disposition of partnership property. Section 752 prescribes the tax treatment of certain partnership transactions,14 and § 752(c) provides that “[f]or purposes of this section, a liability to which property is subject shall, to the extent of the fair market value of such property, be considered as a liability of the owner of the property.” Section 752(c) could be read to apply to a sale or disposition of partnership property, and thus to limit the amount realized to the fair market value of the property transferred. Inconsistent with this interpretation, however, is the language of § 752(d), which specifically mandates that partnership liabilities be treated “in the same manner as liabilities in connection with the sale or exchange [315]*315of property not associated with partnerships.” The apparent conflict of these subsections renders the facial meaning of the statute ambiguous, and therefore we must look to the statute’s structure and legislative history.
Subsections (a) and (b) of §752 prescribe rules for the treatment of liabilities in transactions between a partner and his partnership, and thus for determining the partner’s adjusted basis in his partnership interest. Under § 704(d), a partner’s distributive share of partnership losses is limited to the adjusted basis of his partnership interest. 26 U. S. C. § 704(d) (1976 ed., Supp. V); see Perry, Limited Partnerships and Tax Shelters: The Crane Rule Goes Public, 27 Tax L. Rev. 525, 543 (1972). When partnership liabilities are increased or when a partner takes on the liabilities of the partnership, § 752(a) treats the amount of the increase or the amount assumed as a contribution by the partner to the partnership. This treatment results in an increase in the adjusted basis of the partner’s interest and a concomitant increase in the § 704(d) limit on his distributive share of any partnership loss. Conversely, under § 752(b), a decrease in partnership liabilities or the assumption of a partner’s liabilities by the partnership has the effect of a distribution, thereby reducing the limit on the partner’s distributive share of the partnership’s losses. When property encumbered by liabilities is contributed to or distributed from the partnership, § 752(c) prescribes that the liability shall be considered to be assumed by the transferee only to the extent of the property’s fair market value. Treas. Reg. §1.752-1(c), 26 CFR § 1.752-1(c) (1982).
The legislative history indicates that Congress contemplated this application of § 752(c). Mention of the fair market value limitation occurs only in the context of transactions under subsections (a) and (b).15 The sole reference to subsec[316]*316tion (d) does not discuss the limitation.16 While the legislative history is certainly not conclusive, it indicates that the fair market value limitation of § 752(c) was directed to transactions between a partner and his partnership.17 1 A. Willis, J. Pennell, & P. Postlewaite, Partnership Taxation § 44.03, p. 44-3 (3d ed. 1981); Simmons, Tufts v. Commissioner: Amount Realized Limited to Fair Market Value, 15 U. C. D. L. Rev. 577, 611-613 (1982).
By placing a fair market value limitation on liabilities connected with property contributions to and distributions from partnerships under subsections (a) and (b), Congress apparently intended § 752(c) to prevent a partner from inflating the basis of his partnership interest. Otherwise, a partner with no additional capital at risk in the partnership could raise the § 704(d) limit on his distributive share of partnership losses or could reduce his taxable gain upon disposition of his partner[317]*317ship interest. See Newman, The Resurgence of Footnote 37: Tufts v. Commissioner, 18 Wake Forest L. Rev. 1, 16, n. 116 (1982). There is no potential for similar abuse in the context of § 752(d) sales of partnership interests to unrelated third parties. In light of the above, we interpret subsection (c) to apply only to § 752(a) and (b) transactions, and not to limit the amount realized in a sale or exchange of a partnership interest under § 752(d).
IV
When a taxpayer sells or disposes of property encumbered by a nonrecourse obligation, the Commissioner properly requires him to include among the assets realized the outstanding amount of the obligation. The fair market value of the property is irrelevant to this calculation. We find this interpretation to be consistent with Crane v. Commissioner, 331 U. S. 1 (1947), and to implement the statutory mandate in a reasonable manner. National Muffler Dealers Assn. v. United States, 440 U. S. 472, 476 (1979).
The judgment of the Court of Appeals is therefore reversed.
It is so ordered.
