Holiday Corporation Savings and Retirement Plan ("the Plan") appeals the order of the district court holding that the debtor's interest in an employee benefit plan was property of the bankruptcy estate under 11 U.S.C. Sec. 541(a)(1) and was not excluded under the exception found at Sec. 541(c)(2). Section 541(c)(2) provides that a restriction on the transfer of a beneficial interest of a debtor in a trust that is enforceable under "applicable nonbankruptcy law" is enforceable under the Bankruptcy Code. We reject a narrow interpretation of the phrase "applicable nonbankruptcy law" in Sec. 541(c)(2) as protecting only those debtors' interests which also constitute traditional spendthrift trusts under applicable state law, finding that the plain unambiguous language of the statute encompasses federal law other than that arising under Title 11 as well as state statutory and case law. We therefore hold that a debtor's interests in an ERISA-qualified pension plan are not property of the debtor's bankruptcy estate and thus are not subject to turnover to the trustee in bankruptcy.

The facts in this case are not in dispute.1 On December 22, 1986, Elizabeth Hayes Lucas ("debtor") filed a petition for bankruptcy under Chapter 7 of the Bankruptcy Code. Jane B. Forbes, appellee, was appointed trustee ("trustee"). On the schedule of exempted property, debtor listed a $2,000 exemption in a retirement fund. Inquiries by the trustee revealed that debtor's retirement account was with her employer Holiday Inn Corporation ("Holiday") and that the account was fully vested. As a benefit to employees, Holiday offers participation in a savings and retirement plan ("the Plan"). Debtor claims that the Plan is qualified as a defined contribution plan under Sections 401(a) and (k) of the Internal Revenue Code. It is further alleged that the Plan is subject to the provisions of Titles I, III and IV of the Employee Retirement Income Security Act of 1974 ("ERISA"), 29 U.S.C. Secs. 1001-1461, and contains the anti-alienation clause required by ERISA at 29 U.S.C. Sec. 1056(d)(1).2

On April 20, 1987, Holiday provided the trustee with a copy of debtor's account statement, advising that $5,863.08 was vested as of January 1, 1987. During the period between April and August of 1987, debtor requested and received from Holiday withdrawals of $1,500.00 on April 15, 1987, $1,161.13 on May 7, 1987, and $4,829.98 on August 24, 1987.

On or about April 15, 1987, the trustee filed a complaint for turnover of assets against the debtor and Holiday, seeking the portion of vested benefits disbursed to debtor after the petition was filed. On cross-motions for summary judgment, the bankruptcy court stated that the debtor's pension benefits were not excluded from the bankruptcy estate and that the trustee could recover post-petition distributions from the debtor on the pension fund.3 Lucas, 100 B.R. at 971-72.

The bankruptcy court initially stated that it was conceded that debtor's benefits plan was not a spendthrift trust under Tennessee law and was therefore property of the bankruptcy estate at filing on December 22, 1986. In reaching this conclusion the bankruptcy court cited In re Ridenour, 45 B.R. 72, 78 (Bankr.E.D.Tenn.1984) and In re Faulkner, 79 B.R. 362 (Bankr.E.D.Tenn.1987), both of which relied on a series of decisions which have interpreted the phrase "applicable nonbankruptcy law" in Sec. 541(c)(2) as protecting only those debtors' interests which constitute traditional spendthrift trusts under applicable state law. The bankruptcy court then found that the debtor's employee benefits were not subject to exemption4 under Tenn.Code Ann. Sec. 26-2-111 because the debtor had access to vested benefits greater than that permitted by the statute.5 Finally, the bankruptcy court held that the Supreme Court's decision in Mackey v. Lanier Collection Agency & Service, Inc., 486 U.S. 825, 108 S. Ct. 2182, 100 L. Ed. 2d 836 (1988), did not change this result.6 The district court affirmed without separate opinion 110 B.R. 335.

On appeal to this court, "the Plan" raises the following issues:

1) Whether the district court erred in concluding that debtor's vested pension benefits were property of the estate;

2) Whether the exception contained in Section 541(c)(2) applies only to ERISA-qualified pension plans which also constitute valid spendthrift trusts under relevant state law;

3) If Section 541(c)(2) is not to be so narrowly construed, whether the anti-alienation provisions contained in the Holiday Plan and required by ERISA are enforceable against the trustee; and

4) If Section 541(c)(2) is to be so narrowly construed, whether Tennessee law is preempted by ERISA as to what constitutes a spendthrift trust.

Since the facts in this case are not in dispute and the issues presented involve purely legal questions, the only standard of review with which we need concern ourselves is that governing a bankruptcy court's conclusions of law. Such rulings by a bankruptcy court are subject to de novo review by this court. United States v. Mississippi Valley Generating Co., 364 U.S. 520, 526, 81 S. Ct. 294, 297, 5 L. Ed. 2d 268 (1961); In re Caldwell, 851 F.2d 852, 857 (6th Cir.1988).

The filing of a bankruptcy petition under Title 11 of the United States Code creates an estate comprised of "all legal or equitable interests of the debtor in property as of the commencement of the case." 11 U.S.C. Sec. 541(a)(1) (West 1979 & Supp. 1990). As the legislative history of this section makes clear, the provision was intended to be broad in scope. United States v. Whiting Pools, Inc., 462 U.S. 198, 204-205, 103 S. Ct. 2309, 2313, 76 L. Ed. 2d 515 (1983) (citing S.Rep. No. 95-989, p. 82 (1978); and H.R.Rep. No. 95-595, pp. 367-368 (1977)), U.S.Code Cong. & Admin.News 1978, pp. 5787, 5868, 6323-24.

The Code further provides that "an interest of the debtor in property becomes property of the estate ... notwithstanding any provision ... (A) that restricts or conditions transfer of such interest by the debtor[.]" 11 U.S.C. Sec. 541(c)(1)(A) (West Supp.1990). Paragraph 2 of subsection (c), however, states an exception to the general rule of Sec. 541(c)(1)(A): "A restriction on the transfer of a beneficial interest of the debtor in a trust that is enforceable under applicable nonbankruptcy law is enforceable in a case under this title." 11 U.S.C. Sec. 541(c)(2) (West Supp.1990) (emphasis added). Thus, property of a debtor falling within the definition of this exception is excluded from the bankruptcy estate.

The Plan contends that debtor's interest in the employee benefit plan are excluded from the bankruptcy estate because they are protected by an enforceable restriction on transfer under ERISA which constitutes "applicable nonbankruptcy law" under Sec. 541(c)(2) of the Bankruptcy Code. There is a split among the courts which have considered the issue of whether ERISA constitutes "applicable nonbankruptcy law." Several circuits have interpreted the phrase narrowly, relying on the section's legislative history to hold that Sec. 541(c)(2) was intended to refer only to state "spendthrift trust" law. See In re Daniel, 771 F.2d 1352, 1360 (9th Cir.1985) cert. denied, 475 U.S. 1016, 106 S. Ct. 1199, 89 L. Ed. 2d 313 (1986); In re Lichstrahl, 750 F.2d 1488, 1490 (11th Cir.1985); In re Graham, 726 F.2d 1268 (8th Cir.1984); Matter of Goff, 706 F.2d 574 (5th Cir.1983). Under this view, only those ERISA pension plans which qualify as spendthrift trusts under the applicable state law will be excluded from the property of the bankruptcy estate.

By contrast, a minority of courts have held that ERISA does constitute "applicable nonbankruptcy law", and thus ERISA benefits which are subject to that Act's anti-alienation provisions are excluded from the bankruptcy estate under Sec. 541(c)(2). Courts adopting this position have relied on the plain language of the statute, which on its face does not limit "applicable nonbankruptcy law" to state spendthrift trust law. These courts reason that the legislative history does not evidence an attempt by Congress to restrict the scope of Sec. 541(c)(2) to state spendthrift trust law, but simply reflects a ratification of a long-standing prior law honoring state spendthrift trust law. See In re Moore, 907 F.2d 1476 (4th Cir.1990); In re Majul, 119 B.R. 118 (Bankr.W.D.Tex.1990); In re Threewitt, 24 B.R. 927 (D.Kan.1982); In re Komet, 104 B.R. 799 (Bankr.W.D.Tex.1989); In re Ralstin, 61 B.R. 502 (Bankr.D.Kan.1986); In re Mosley, 42 B.R. 181 (Bankr.D.N.J.1984); Warren v. G.M. Scott & Sons, 34 B.R. 543 (Bankr.S.D.Ohio 1983); see also In re Kincaid, 917 F.2d 1162 (9th Cir.1990) (Fletcher, J., concurring).

It is an axiom of statutory construction that resort to legislative history is improper when a statute is unambiguous.

Legislative history can be a legitimate guide to a statutory purpose obscured by ambiguity, but "[i]n the absence of a 'clearly expressed legislative intention to the contrary,' the language of the statute itself 'must ordinarily be regarded as conclusive.' " Unless exceptional circumstances dictate otherwise, "[w]hen we find the terms of a statute unambiguous, judicial inquiry is complete."Burlington Northern R.R. v. Oklahoma Tax Comm'n, 481 U.S. 454, 461, 107 S. Ct. 1855, 1860, 95 L. Ed. 2d 404 (1987) (citations omitted); see also Davis v. Michigan Dep't of Treasury, 489 U.S. 803, 808 n. 3, 109 S. Ct. 1500, 1504 n. 3, 103 L. Ed. 2d 891 (1989). Similarly, this court has stated that

[i]n determining the meaning of legislation, we must look to the plain language of the statute itself. If we find that the statutory language is unambiguous, then that language is regarded as conclusive unless there is a clearly expressed legislative intent to the contrary. If we find that the statute is ambiguous, we then look to its legislative history.

Bradley v. Austin, 841 F.2d 1288, 1293 (6th Cir.1988) (citations omitted).

Applying this familiar principle, we find that the language of Sec. 541(c)(2) is clear and unambiguous and that the resort to the legislative history of Sec. 541(c)(2) as an interpretive tool is therefore inappropriate. Thus, we reject the position of those courts which rely on the legislative history to conclude that "applicable nonbankruptcy law" refers exclusively to state spendthrift law. In this regard we are persuaded by the Fourth Circuit's recent decision in Moore, supra, which dealt with the same issue before us. In concluding that the debtor's interests in an ERISA-qualified profit sharing and pension plan were not subject to turnover because the Bankruptcy Code recognizes as dispositive the protection of an enforceable restriction on transfer under ERISA, the Fourth Circuit held:

"Applicable nonbankruptcy law" means precisely what it says: all laws, state and federal, under which a transfer restriction is enforceable. Nothing in the phrase "applicable nonbankruptcy law" or in the remainder of Sec. 541(c)(2) suggests that the phrase refers exclusively to state law, much less to state spendthrift trust law.

Moore, 907 F.2d at 1477.

The Fourth Circuit based its decision on several factors. First, it noted that a narrow interpretation of the statute, in addition to violating the plain language of Sec. 541(c)(2), is also inconsistent with other uses of the identical phrase throughout the Bankruptcy Code, where the phrase is used to refer to the federal as well as state law. Moore, 907 F.2d at 1477.7 The court reasoned that because words are presumed to have the same meaning in all subsections of the same statute, Moore, 907 F.2d at 1478 (citing Morrison-Knudsen Constr. Co. v. Director, OWCP, 461 U.S. 624, 633, 103 S. Ct. 2045, 2050, 76 L. Ed. 2d 194 (1983)), it would be incongruous to give different constructions to an identical phrase at various sections of the Code, especially since the disparate parts of the statute were enacted together in a single comprehensive statute. Moore, 907 F.2d at 1478.

Second, the Moore court observed that other provisions of the Bankruptcy Code demonstrate that when Congress intended to refer to state law, it did so expressly. Id.8 And, as noted in Threewitt, supra, since Congress did not use the term "spendthrift trust" in the language of the section itself, "there is no reason to suppose that when the term appears in the legislative history it should be taken as a term of art...." 24 B.R. at 929. See also Ralstin, supra, 61 B.R. at 503 ("[I]f Congress had intended Sec. 541(c)(2) to apply only to state spendthrift trusts, the term 'spendthrift trust' would have appeared in the statute, rather than the phrase 'applicable nonbankruptcy law.' ").

Finally, we also find, as did the Fourth Circuit, that even if the legislative history were relevant, it is inconclusive. See Moore, supra, 907 F.2d at 1479. The only place where the term 'spendthrift trust' is found is in the House and Senate reports. See H.R.Rep. No. 595, 95th Cong., 1st Sess. 369 (1977), reprinted in 1978 U.S.Code Cong. & Admin.News pp. 5787, 6325 (stating that the term "applicable nonbankruptcy law" in Sec. 541(c)(2) "preserves the restrictions on transfer of a spendthrift trust to the extent that the restriction is enforceable under applicable nonbankruptcy law"); and S.Rep. No. 989, 95th Cong.2d Sess. 83, reported in 1978 U.S.Code Cong. & Admin.News 5787, 5869 (explaining that Sec. 541(c)(2) "preserves restrictions on a transfer of a spendthrift trust...."). Rather than indicating that Sec. 541(c)(2) was intended to refer only to spendthrift trusts, these reports merely clarify that Sec. 541(c)(2) was intended to continue the exclusion of spendthrift trusts to the extent they are protected from creditors under applicable state law. Ralstin, supra, 61 B.R. at 503; Komet, supra, 104 B.R. at 811 (stating that Sec. 541(c)(2), "far from expressing any particularly new congressional policy, ... simply ratified long-standing prior law honoring state spendthrift trust law. Nothing more need be read into its enactment."); see also Moore, supra, 907 F.2d at 1479 (stating that "[a]t most, these passages suggest that Congress intended state spendthrift trust law to be included within the meaning of 'applicable nonbankruptcy law.' "). We agree with the reasoning of the Fourth Circuit in Moore and other courts following the minority opinion.

Our next inquiry is whether ERISA contains an enforceable transfer restriction that would cause it to fall within the meaning of the term "applicable nonbankruptcy law." See Moore, supra, 907 F.2d at 1479. This determination requires an interpretation of two coordinate federal statutes--ERISA and the Bankruptcy Code. Our analysis is therefore governed by another principle of statutory construction; namely that we must give full effect to both statutes. Moore, 907 F.2d at 1479 (citing Morton v. Mancari, 417 U.S. 535, 551, 94 S. Ct. 2474, 2483, 41 L. Ed. 2d 290 (1974)).

In Connolly v. Pension Benefit Guaranty Corp., 475 U.S. 211, 106 S. Ct. 1018, 89 L. Ed. 2d 166 (1986), the Supreme Court reviewed the legislative purpose of ERISA, stating:

Congress enacted ERISA in 1974 to provide comprehensive regulation for private pension plans. In addition to prescribing standards for the funding, management, and benefit provisions of these plans, ERISA also established a system of pension benefit insurance. This "comprehensive and reticulated statute" was designed to ensure that employees and their beneficiaries would not be deprived of anticipated retirement benefits by the termination of pension plans before sufficient funds have been accumulated in the plans.... Congress wanted to guarantee that 'if a worker has been promised a defined pension benefit upon retirement--and if he has fulfilled whatever conditions are required to obtain a vested benefit--he will actually receive it.' "

Connolly, 475 U.S. at 214, 106 S.Ct. at 1020 (quoting Pension Benefit Guaranty Corp. v. R.A. Gray & Co., 467 U.S. 717, 720, 104 S. Ct. 2709, 2713, 81 L. Ed. 2d 601 (1984) (citation omitted)). One of the means by which ERISA protects workers' pension benefits is through provisions against assignment or alienation of plan benefits.9 29 U.S.C. Sec. 1056(d)(1) states that "[e]ach pension plan shall provide that benefits provided under the plan may not be assigned or alienated." Likewise, 26 U.S.C. Sec. 401(a)(13) of the Internal Revenue Code requires that in order for an ERISA pension plan to receive tax-exempt status, it must provide that benefits under the plan may not be assigned or alienated. See also Treas.Reg. Sec. 1.403(a)-13(b)(1). Under Sec. 1056(d)(1) then, all encroachments, both voluntary and involuntary, are prohibited. General Motors Corp. v. Buha, 623 F.2d 455, 460 (6th Cir.1980). Thus, a debtor's interest in an ERISA pension fund is beyond the reach of his general creditors. Id. at 463. We therefore find, as did the Moore and Threewitt courts, that " '[u]nder the plain and simple language of Section 541(c)(2), if the ERISA anti-alienation provisions are enforceable against general creditors, they are enforceable against the bankruptcy trustee.' " Moore, 907 F.2d at 1480 (quoting Threewitt, supra, 24 B.R. at 929).

This conclusion has several favorable results. First, it harmonizes the Bankruptcy Code, ERISA, and the Internal Revenue Code and gives full effect to the express language of those statutes. Second, it prevents a plan from being subject to disqualification and loss of tax-exempt status when a bankruptcy trustee seeks turnover of a single debtor's interest in a plan. See Moore, 907 F.2d at 1480. Finally, it guarantees uniform treatment of benefits throughout the country. As noted by this court in Buha, supra :

It is central to the statutory scheme that ERISA not be subject to state and local laws which might frustrate its goals. This was emphasized by Representative Dent, Chairman of the Subcommittee on Labor of the House Committee on Education and Labor, who stated:

Finally, I wish to make note of what is to many the crowning achievement of this legislation, the reservation to Federal authority the sole power to regulate the field of employee benefit plans. With the preemption of the field, we round out the protection afforded participants by eliminating the threat of conflicting and inconsistent state and local regulation. 120 Cong.Rec. 29197 (1974).

623 F.2d at 459.

In light of our disposition of this case, we need not address the Plan's remaining arguments. For the reasons stated above, the judgment of the district court is REVERSED and REMANDED. The district court and/or the bankruptcy court is directed to make findings as to whether the Holiday Plan constitutes a pension plan within the meaning of 29 U.S.C. Sec. 1056(d)(1).
