These companion income tax cases call upon us to construe and apply the war loss provisions of the 1939 and 1954 Internal Revenue Codes.1 Under Section 127 of the 1939 Code (carried over into Sections 1331-1336 of the 1954 Code), property owned by Americans in enemy countries (including interests in such property represented by securities) was deemed to be destroyed or lost upon the declaration of war — without regard to the possible return of the property, or an award of compensation, at the war’s end. The taxpayer could immediately take a war loss deduction for such enemy-held property to the extent the deduction would do him any good.2 The entire property was thereafter deemed, until recovered, non-existent for all income tax purposes (whether or not a war loss deduction was taken); it was treated as if the taxpayer no longer had any interest in it. Shahmoon v. Commissioner, 185 F.2d 384 (C.A. 2, 1950) (no depreciation allowed after war loss deduction) ; Kenmore v. Commissioner, 205 F.2d 90 (C.A. 2, 1953) (no fire loss allowed) ; Weinmann v. United States, 278 F.2d 474 (C.A. 2, 1960); Wyman v. United States, 166 F.Supp. 766, 143 Ct. Cl. 846 (1958); Dix v. Commissioner, 34 T.C. 837, 841 (1960). During the time of loss there was a complete void; the statute “is to be read as though the property had ceased to exist during the period of enemy occupation.” Kenmore, supra, 205 F.2d at 92. After the close of hostilities, however, it was anticipated that there could be a recovery of the war loss through repossession of the lost property or its equivalent; the Code covers the incidents and operation of such a recovery. The basis of property recovered “in respect of” war-lost property is expressly established as “an amount equal to the fair market value of such property, determined as of the date *881of the recovery.” 3 The recovery must be used in computing gain (in the year of recovery) but there is no taxable income until the taxpayer’s total war loss recovery exceeds his unused war loss (that part of the potential war loss deduction which did not result in a tax benefit). The part of that excess which is equivalent to the amount used for a tax benefit at the time of the war loss deduction is then taxed as ordinary income; the remainder is handled as gain from an involuntary conversion (taxed at capital gain rates, if at all).
When this country entered World War II in December 1941, Paul R. G. Horst (whom we shall designate the taxpayer) owned a sizeable amount of Japanese and Italian bonds. Under the Code’s war loss provisions, his total loss on those bonds was $746,459.25,4 but, since his 1941 income was much smaller, he received a tax benefit from only a minor part ($99,923.22) of this total; his “unused war loss” amounted to the difference ($646,536.03). After the war, he had a war loss recovery, it is agreed, in 1947 “in respect of” his Italian bonds (not now involved), and in 1950 for his Japanese bonds. The total basis of the property included in these recoveries was $425,891.94. Since this was considerably less than his unused war loss, he was not required to pay a tax on the recovery.
The recovery “in respect of” the Japanese bonds occurred in November 1950 when trading restrictions on those securities were lifted and trading recommenced after almost a decade. At that time, the bonds, on which no interest had been paid since 1941, were traded flat, i. e., the quoted price included both principal and accrued but unpaid interest. This combined market value amounted, in November 1950, to $251,146.25. As we have pointed out, this sum, taken together with the earlier recovery on the Italian bonds, was considerably less than the taxpayer's unused war loss for 1941.
Service on the Japanese instruments was not resumed until after December 22, 1952, when the Japanese Government (which had taken over all the obligations) offered to extend for ten years the maturity date on each bond, as well as on each accrued but unpaid interest coupon; the extended coupons were to be detached and treated separately from their bonds. This taxpayer accepted the offer and received extended bonds and interest coupons. Later, as the coupons which were matured but unpaid in November 1950 were honored (in 1952-1959), he reported these payments as ordinary income in the years of receipt. He also paid income tax on the coupons (and other interest obligations) which had not yet accrued by November 1950.
In the present suits, the plaintiffs seek refunds of the taxes collected on the payments of the accrued but unpaid coupons (but not of the taxes paid on the interest accruing after November 1950). The taxpayer’s position is that, under the war loss statute and the accepted rule relating to the acquisition of bonds flat, these late payments were returns of capital, not taxable income. Defendant insists that the interest payments were necessarily income by their very nature.
*882This question cannot be properly decided, in our view, by resting on un-anchored general principles tied to the ordinary status of interest payments, while at the same time disregarding the special tax scheme established by Congress, first under the 1939 Code and then re-adopted in the 1954 Code, for World War II losses. That self-contained system is decisive; our problem must be solved within the circle of its detailed requirements.
In that special statute, Congress directed that, for federal income tax purposes, taxpayer’s Japanese bonds be “considered as destroyed or seized” in 1941; as the cases (cited supra) uniformly hold, the war loss provisions demand that, whatever the law of contracts or of negotiable instruments may say, we must act as if thereafter he had no such property until 1950. When in that year he had a war loss recovery “in respect of” his lost property, the bonds were being traded flat and their market value included the worth of the defaulted interest coupons. The statute specifically declares that taxpayer’s basis for the recovered property is “the fair market value of such property, determined as of the date of the recovery.” This new value, including the unseparated portion attributable to the accrued but unpaid interest, was utilized in computing the taxpayer’s income for 1950, but he did not have to pay any tax thereon because his total war loss exceeded his total recovery. Nevertheless, the recovery was taken into account, and had to be taken into account, in determining his taxable income. Having thus passed through the income tax strainer, the bonds became capital assets, with a single basis reflecting both principal and defaulted interest (because that is what the “fair market value” of the property embraced on the recovery date). Under one of the fundamental principles of income taxation, the taxpayer is entitled to a full return of this basis before being taxed on any gain. It is also settled that those who purchase, flat, bonds with defaulted interest coupons are not required to treat later interest payments as ordinary income; the payments are but partial returns of the investment in the securities. Campbell v. Sailer, 224 F.2d 641 (C.A. 5, 1955); National City Lines, Inc. v. United States, 197 F.2d 754, 756, 757 (C.A. 3, 1952); Clyde C. Pierce Corp. v. Commissioner, 120 F.2d 206 (C.A. 5, 1941); Rickaby v. Commissioner, 27 T.C. 886 (1957) (acq. 1960-2 C.B. 6). See, also, United States v. Langston, 308 F.2d 729, 730-731 (C.A. 5, 1962); Jaglom v. Commissioner, 303 F.2d 847, 849-850 (C.A. 2, 1962); McDonald v. Commissioner, 217 F.2d 475, 476 (C.A. 6, 1954). Similarly this taxpayer’s acquisition of the bonds flat in 1950 (via the war-loss-recovery statute) entitles him to recover, free of tax, the capital which became his in that year, under the special system Congress established.
We see no sufficient reason why the well-entrenched flat purchase rule should be avoided here. The taxpayer was not a purchaser, and he did not buy the bonds in 1950. By force of the statute, however, he was a “war loss recoverer” who has to be treated as if he had newly acquired the property at its fair market value in 1950. The theory of the flat purchase rule — that one who receives a bond along with accrued but unpaid interest obtains a single piece of property, not part capital and part income — fits squarely with this statutory acquisition Congress created for a war loss reeoverer. The defendant counters that the rule’s true rationale is that the later payment to the purchaser of pre-existing defaulted interest is not a payment for the use of his money but merely satisfaction of an obligation already owing at the time he bought the bond; on the other hand, the like payments here, it is said, were for the use of taxpayer’s money (lent to the Japanese before the war) and must therefore be deemed income. This argument turns its back on the war loss statute which erases, for tax purposes, the taxpayer’s prior property and transactions, once he has a war loss; from then until the time of recovery there is, in effect, a vacuum for the world of *883the income tax; as of the recovery, the recoverer is placed in the same position taxwise as the purchaser of bonds flat— the accrued interest is an obligation owing at the time he acquires or reacquires the bonds. There is no relevant distinction between the purchaser of bonds flat and the war loss recoverer.
The force of the special statute likewise undermines the defendant’s related arguments. When the taxpayer deducted his war loss on the Japanese bonds in 1941, he properly deducted only the cost of the bonds and not the subsequently accruing interest for the period 1942-1952; it is urged, therefore, that not only did the flat bonds of 1950 cover more than the property lost in 1941 but also that the part of the 1950 cost attributable to the defaulted interest necessarily represented something not lost at all in 1941. The answer is that the statute contemplates the recovery of property other than the precise war-lost items when it refers to property recovered “in respect of” property considered as destroyed or seized. A farm with substantial new improvements, added since the loss, would be recovered “in respect of” the old war-lost farm. The flat bonds are not dissimilar. The whole value of those instruments, principal plus accrued interest, represented the “property recovered in respect of property considered as destroyed or seized” — just as with the enhanced value of the improved farm. The former property carries along, and incorporates, its integral increments. Nor is it material that, in our situation, there is no one who will pay an income tax on the accrued interest if the taxpayer is now relieved.5 The war loss statute, as we have explained, provides its own separate method for taxing recoveries. The recovery in 1950 had to be taken into account in determining the taxpayer’s income tax for that year. In this instance, the formula provided by the statute happened to require no tax — because of the magnitude of the total war loss as compared to the useable deduction allowed for 1941 — but the legal situation would certainly be no different if the taxpayer had had to pay a tax on the defaulted interest at the time of recovery. In any event, the applicability of the flat purchase rule cannot depend on the existence of another party available to pay a tax on the “interest.” A purchaser otherwise free of income tax on the interest, under the rule, would not become liable because his particular vendor happened to be exempt from the income tax (e. g., a diplomat or a nonprofit institution) or turned out to have large counterbalancing deductions.
Still another defense is that payment of the pre-1950 interest coupons cannot be held part of a capital transaction (giving rise to capital gain once basis has been returned) because there is no “sale or exchange.” It is implicit in what we have said that one answer lies in the special war loss statute which both treats a war loss recoverer as newly acquiring the property and also instructs him to take the recovery into account in computing his income tax. A separate reply is given by Section 117(f) of the 1939 Code:
“For the purposes of this chapter, amounts received by the holder upon the retirement of bonds, debentures, notes, or certificates or other evidences of indebtedness issued by any corporation (including those issued by a government or political subdivision thereof), with interest coupons or in registered form, shall be considered as amounts received in exchange therefor.” 6
This provision applies to the payment of accrued but defaulted interest on coupon bonds, as well as to principal, even though. *884the taxpayer’s basis has already been recovered. Campbell v. Sailer, supra, 224 F.2d 641, 643 (C.A. 5, 1955); Rickaby v. Commissioner, supra, 27 T.C. 886 (1957) (acq. 1960-2 C.B. 6); Rev.Rul. 60-284, 1960-2 C.B. 464. Through Section 117(f), any requirement that there be an “exchange” is met.7
Although on its surface Shafer v. United States, 204 F.Supp. 473 (S.D.Ohio, 1962), aff'd on opinion below, 312 F.2d 747 (C.A. 6,1963), may appear to support defendant in actuality it does not. The plaintiffs point out that Shafer, unlike Horst, had elected to revert to his prewar-loss cost basis (see footnote 3, supra). That 1941 basis obviously did not reflect the subsequent defaulted interest; accordingly, when the after-accruing interest was belatedly paid, Shafer received income, not a return of his basis. This taxpayer, on the other hand, accepted the later date-of-recovery for his basis, and he is therefore entitled under the statute to recover the already-accrued interest reflected in that basis.
It follows, we think, that faithful adherence to the terms and implications of the war loss statute allows this taxpayer to treat the payments of the disputed defaulted interest as a return of capital and, once his basis was recovered, as capital gain, not ordinary income. That is what Congress has directed in enacting and re-enacting the legislation.
The parties are agreed, and we so hold, that for the three years involved in No. 117-62, the taxpayer was entitled to an exemption of $600 (for his non-resident alien wife) which he failed to take in his returns.
Plaintiffs are entitled to recover in both cases. The amount of recovery will be determined under Rule 47(c) (2).
. The two suits present exactly the same war loss issue for different years, and we shall therefore treat them as a single case. In No. 117-62, there is also a minor issue upon which the parties are now agreed.
. The remainder of the loss became his “unused war loss.”
. The statute required the taxpayer to treat his loss on the Japanese and Italian bonds as one integral loss, not as separate losses. This is true throughout the statutory scheme for war losses and war loss recoveries. The Japanese loss and the Italian loss must be considered as a unit.
. In flat purchase cases, the courts have held the seller liable for ordinary income tax on the portion of the flat price attributable to the accrued interest. Jaglom v. Commissioner, supra; United States v. Langston, supra; First Kentucky Co. v. Gray, 309 F.2d 845 (C.A.6, 1962).
. For these cases, Section 1232(a) of the 1954 Code is substantially the same.
. In this connection, the Government raises a secondary defense, as to a portion of the tax, arising out of the double fact that, under the 1952 arrangement with Japan, the bonds could be redeemed by the obligor prior to their new maturity dates but the interest coupons were detached and given separate existence. Japan did redeem certain of the bonds early, while continuing to pay the detached coupons on their extended maturity dates. (Taxpayer received, from 1953 through 1959, a total of over $49,-000 in payment for such coupons relating to previously-redeemed bonds. In each instance the redemption-amount exceeded the cost basis of the bonds and the related coupons.) The defendant maintains that, at the least, gain attributable to amounts received in payment of the interest coupons after redemption of the bonds to which they relate is taxable as ordinary income. We think, however, that all the interest coupons which were accrued by the time of the war loss recovery in 1950 were part of the bonds then acquired (reflected in the bonds’ basis at that time) and the bonds were not wholly retired until these coupons were paid. This position is consistent with the basic theory of the Campbell and Rickaby decisions. See, also, Clyde C. Pierce Corp. v. Commissioner, supra, 120 F.2d 206, 208 (C.A.5, 1941).
