OPINION
This tax refund suit is before the court after oral argument on cross-motions for partial summary judgment. At issue is whether the taxpayer is entitled to application of a zero net interest rate to overlapping periods of mutual indebtedness between the taxpayer and the government in connection with tax years 1974, 1975, 1983, and 1986. For the reasons set forth below, plaintiff’s motion for partial summary judgment is granted and defendant’s cross-motion is denied.
FACTS
Plaintiff, Federal National Mortgage Association (“Fannie Mae”), provides liquidity for mortgage investments, primarily by purchasing mortgages from lenders with funds generated through the issuance of equity and debt securities. Originally created as a federal government agency, Fannie Mae became a privately owned, for-profit entity in 1968.
In February 1994, pursuant to its opinion in Federal Nat’l Mortgage Ass’n v. Commissioner,
In December 1999, Fannie Mae filed an administrative claim with the IRS pursuant to I.R.C. § 6621(d).
Elimination of interest on overlapping periods of tax overpayments and under*230 payments. — To the extent that, for any period, interest is payable under subchap-ter A and allowable under subchapter B on equivalent underpayments and overpay-ments by the same taxpayer of tax imposed by this title, the net rate of interest under this section on such amounts shall be zero for such period.
1. R.C. § 6621(d).
Special rule. — Subject to any applicable statute of limitation not having expired with regard to either a tax underpayment or a tax overpayment, the amendments made by this section shall apply to interest for periods beginning before the date of the enactment of this Act if the taxpayer—
(A) reasonably identifies and establishes periods of such tax overpayments and underpayments for which the zero rate applies; and
(B) not later than December 31, 1999, requests the Secretary of the Treasury to apply section 6621(d) of the Internal Revenue Code of 1986 ... to such periods.
Pub.L. No. 105-206, § 3301(c)(2), 112 Stat. 685, 741 (1998), amended by Pub.L. No. 105-277, § 4002(d), 112 Stat. 2681, 2681-906 (1998).
The IRS disallowed Fannie Mae’s claim on June 7, 2000 (with a corrected notice of disal-lowance issued on July 20, 2000). In support of its determination, the IRS relied on its Revenue Procedure 99-43,
Fannie Mae disputes the IRS’s interpretation of the Act’s special rule. Plaintiff reads the condition “[sjubject to any applicable statute of limitation not having expired with regard to either a tax underpayment or a tax overpayment” as authorizing the IRS to perform global interest netting as long as the statute of limitations has not closed on either the overpayment period or the underpayment period. Because the overpayment years were not time barred on July 22, 1998, Fannie Mae now seeks to compel the IRS to refund either an additional $9,924,876 in overpayment interest or funds otherwise implementing a zero net interest rate, as well as statutory interest and costs.
DISCUSSION
The issue for resolution is the correct interpretation of the special rule that extends the interest-netting benefits of section 6621(d) to past periods. This is a question of first impression in the federal courts. Narrowly viewed, the parties’ controversy cen
I.
A.
Given that no federal court has yet explored the meaning of the special rule or section 6621(d), an examination of the circumstances leading to their enactment is warranted. Since 1986, the IRS has collected interest on tax underpayments by corporate taxpayers at a higher rate than it pays interest on tax overpayments. See Tax Reform Act of 1986, Pub.L. No. 99-514, § 1511(a), 100 Stat.2085, 2744.
The IRS routinely uses certain means of minimizing taxpayer liability in situations of mutual indebtedness. First, the IRS offsets outstanding overpayments of tax against bal-anees due and unpaid. See I.R.C. § 6402(a) (“In the case of any overpayment, the Secretary ... may credit the amount ... against any liability in respect of an internal revenue tax ____”). Although the IRS’s offsetting power is discretionary, its policy is to offset all outstanding overpayments and underpayments that simultaneously register on its master system. See IRS Notice 96-18,1996-
In all other cases where either the underpayment or the overpayment has been satisfied, the IRS’s practice is to assess or credit interest on each liability separately at the applicable statutory rate. In these circumstances, an overlapping mutual obligation between the IRS and a taxpayer will generate a net liability on the taxpayer’s part, even where the amounts of the underpayment and of the overpayment are identical. This outcome is consistent with the IRS’s longstanding practice of treating each tax liability as separate and distinct, a position that has been upheld by the federal courts on several occasions. See, e.g., Babcock & Wilcox Co. v. Pedrkk,
B.
Upon enacting the interest differential in 1986, Congress demonstrated sensitivity to this criticism. The Conference Report aer companying that enactment noted that the new law provided Treasury with three years during which to prescribe regulations providing for the netting of overpayments and underpayments. See H.R. Conf. Rep. No. 99-841, pt. 4, at 785 (1986), U.S.Code Cong. & Admin.News 1986, at 4075, 4873. By the end .of this period, the report stated, “the IRS should have implemented the most comprehensive netting procedures that are consistent with sound administrative practice.” Id. In 1990, Congress both increased the interest differential and reiterated its desire that the IRS establish comprehensive netting procedures. H.R. Conf. Rep. No. 101-964, at 1101 (1990), reprinted in 1990 U.S.C.C.A.N. 2374 (accompanying the Omnibus Budget Reconciliation Act of 1990, Pub.L. No. 101-508,104 Stat. 1388). By 1994, in conjunction with yet another increase, Congress urged the IRS to act “as rapidly as possible.” S.Rep. No. 103-412, at 144 (1994) (accompanying the Uruguay Round Agreements Act, Pub.L. No. 103-465,108 Stat. 4809 (1994)).
Throughout this period, however, the IRS maintained that it lacked authority to perform the sort of “global netting” envisioned by Congress. Global netting combines and expands the offsetting and annual netting approaches. Like offsetting, global netting balances a taxpayer’s overpayment against its underpayment of a different tax liability, including liabilities from different tax years. But like annual netting, global netting can be used where the balance payable and/or the balance due are no longer outstanding. Two approaches to global netting exist. The first approach extends I.R.C. § 6402(a)’s offsetting power by using I.R.C. § 6601(f) to nullify the interest differential between a previously refunded overpayment and a tax deficiency, or between an overpayment and a previously paid deficiency. The second approach is interest equalization, which simply manipulates interest rates in order to achieve a net rate of zero for the periods during which overpayments overlap with underpayments due. Actual tax balances are not affected by this second approach, which does not rely on the IRS’s offsetting authority. Rather, netting is accomplished either by reducing the amount of underpayment interest below the statutory rate (to match the overpayment rate), or by increasing the amount of overpayment interest above the statutory rate (to match the underpayment rate).
The IRS claimed that neither the offsetting nor the interest equalization approach was permissible absent additional statutory authority. The IRS conceded that section 6601(f) required the netting of interest where the IRS opted to use section 6402(a)’s offsetting power. However, Treasury regulations implementing section 6402(a) interpreted the term “liability” to mean “outstanding liability.”' See Treas. Reg. § 301.6402-1 (2002). Because a fully paid tax liability could no longer be considered outstanding, circumstances requiring global netting necessarily would fall outside the purview of section 6402(a) and fail to trigger section 6601(f). See Michael I. Saltzman, IRS Practice and Procedure ¶ 6.02[3][d] n. 127 (rev.3d ed.2002). The Eighth Circuit upheld this reading of the statute in Northern States Power Co. v. United States,
The IRS also maintained that it lacked authority to apply an interest equalization approach to global netting. The mandatory language of the interest-setting sections of the Internal Revenue Code, it argued, re
In July 1996, Congress commissioned a study of global interest netting by the Secretary of the Treasury. See Taxpayer Bill of Rights 2, Pub.L. No. 104-168, § 1208, 110 Stat. 1453,1473 (1996).
C.
In section 6621(d), introduced in the House of Representatives in October 1997 and enacted into law the following July, Congress adopted the interest equalization approach to global netting but rejected the remainder of the Treasury Report’s recommendations in whole or in part. The new statute neither required one non-zero-balance year nor limited global netting to income taxes only. Rather, global netting was made available “for any period” and for any “tax imposed by this title.” I.R.C. § 6621(d). Additionally, Congress declined to place the burden of seeking global netting on the taxpayer, requiring instead that the IRS automatically apply a zero net interest rate to overlapping liabilities. Id.
The new statute also provided for retrospective application of global interest netting — a possibility the Treasury Report did not address. The original bill (H.R.2676) operated purely prospectively. See H.R.Rep. No. 105-364(1), at 21 (1997). However, a Senate floor amendment to the bill in May 1998 added the special rule that permits taxpayers to seek global interest netting for taxable periods commencing before the effective date of section 6621(d):
Special rule. — Subject to any applicable statute of limitation not having expired with regard to either a tax underpayment or a tax overpayment, the amendments made by this section shall apply to interest for periods beginning before the date of the enactment of this Act if the taxpayer—
*234 (A) reasonably identifies and establishes periods of such tax overpayments and underpayments for which the zero rate applies; and
(B) not later than December 31, 1999, requests the Secretary of the Treasury to apply section 6621(d) of the Internal Revenue Code of 1986 ... to such periods.
144 Cong. Rec. S4,546 (daily ed. May 7, 1998). Inexplicably, the enrolled version of the bill omitted the introductory language in the special rule addressing statutes of limitations and provided only that “[t]he amendments made by this section shall apply to interest for periods beginning before the date of the enactment of this Act.” Pub.L. No. 105-206, § 3301(c)(2),
II.
It is axiomatic that the starting point for an exercise in statutory interpretation is the language of the statute itself. Duncan v. Walker,
Both plaintiff and defendant focus on the opening language of the special rule: “Subject to any applicable statute of limitation not having expired with regard to either a tax underpayment or a tax overpayment ....” Each party has acknowledged that the language is ambiguous, “convoluted,” and “awkwardly written.” This language lends itself equally to two divergent interpretations: either it imposes a restriction on the availability of global interest netting for past periods (defendant’s position), or it simply clarifies that general statute of limitations rules apply retrospectively as well as prospectively (plaintiffs position). Congress’s choice of the expansive word “any” exacerbates the interpretive difficulties. Because “any” may mean both “one” and “all,” Webster’s II New College Dictionary 51 (1995), it is impossible to tell from the plain language of the statute whether Congress intended that the expiration of any statute of limitations renders a claim beyond the purview of the special rule, or that as long as any statute of limitations remains open, the special rule is applicable.
Because the statute is unclear, defendant urges the court to rely on the IRS’s Revenue Procedure 99-43, 1999-
A.
There is little basis for defendant’s claim that IRS revenue procedures are “like
Leaving aside the question of whether the existence of a right to global interest netting is truly a “procedural” rather than a “substantive” matter, defendant’s statement conflicts with the definitions of revenue procedures and revenue rulings as set forth in Treasury regulations. Those regulations define a “revenue ruling” as “an official interpretation by the [IRS] ... published for the information and guidance of taxpayers, [IRS] officials, and others concerned.” Treas. Reg. § 601.601(d)(2)(i)(a) (2002). In comparison, a “revenue procedure” is defined as “a statement of procedure that affects the rights or duties of taxpayers or other members of the public under the Code and related statutes or information that, although not necessarily affecting the rights and duties of the public, should be a matter of public knowledge.” Treas. Reg. § 601.601(d)(2)(b) (2002). No statutory interpretation function is ascribed to revenue procedures.
The Court’s decision in United States v. Mead Corp.,
Treasury regulations undoubtedly enjoy Chevron deference. See United States v. Correll,
Defendant argues that because Revenue Procedure 99 — 13,
B.
Although not controlling, revenue procedures, like other interpretive regulations, “constitute a body of experience and informed judgment to which courts and litigants may properly resort for guidance.” Mead,
The fair measure of deference to an agency administering its own statute has been understood to vary with circumstances, and courts have looked to the degree of the agency’s care, its consistency, formality, and relative expertness, and to the persuasiveness of the agency’s position.
Id. at 228,
Revenue Procedure 99-43,
The consistency of an IRS interpretive rule with earlier pronouncements has been an important factor in Supreme Court cases upholding IRS interpretive rulings. In Davis v. United States,
Although the [IRS’s] interpretive rulings do not have the force and effect of regulations, see Bartels v. Birmingham,332 U.S. 126 , 132,67 S.Ct. 1547 ,91 L.Ed. 1947 (1947), we give an agency’s interpretations and practices considerable weight where they involve the contemporaneous construction of a statute and where they have been in long use. See, e.g., Norwegian Nitrogen Products Co. v. United States,288 U.S. 294 , 315,53 S.Ct. 350 ,77 L.Ed. 796 (1933).
Id. at 484,
Moreover, the IRS’s interpretation of the special rule appears inconsistent with its revenue procedure addressing section 6621(d). In Revenue Procedure 2000-26, 2000-
Because Revenue Procedure 99-43 contains no reasoning, cannot claim validity as a long-standing interpretation, and arguably conflicts with other IRS statements of procedure, we afford it little weight.
C.
Because Chevron deference does not apply, we also examine the legislative history behind section 6621(d) and the special rule. See Shell Petroleum, Inc. v. United States,
As mentioned earlier, the special rule came about as the result of a Senate floor amendment that occurred relatively late in the events leading up to the enactment of section 6621(d). A description of the statute of limitations proviso is contained in the Conference Report dated June 24,1998: “[T]he provision applies to interest for periods beginning before the date of enactment if: (1) the statute of limitations has not expired with respect to either the underpayment or overpayment ....” H.R. Conf. Rep. No. 105-599, at 257 (1998). According to plaintiff, this description “even more plainly supports Fannie Mae’s position.” Not surprisingly, defendant disagrees, suggesting that “[t]his language is more naturally read as indicating that both periods must be open.” In the court’s opinion, the proffered language lends itself equally to both parties’ interpretations and is therefore of little value here.
Next, we turn to the technical amendment to the special rule. Plaintiff claims that defendant’s interpretation would impermissibly narrow the scope of the special rule beyond the appropriate role of a technical correction. This argument is without merit under the circumstances of this case, where the statute was amended by the enacting Congress and only three months after it was promulgated. Here, the technical correction served to repair a scrivener’s error, not to close an inadvertently created and subsequently exploited loophole. Contrary to plaintiffs contentions, a technical correction that merely restores the rule Congress intended to enact cannot be construed as a fundamental change in the operation of the statute.
Defendant relies heavily on the 1997 Treasury Report to support its interpretation of the proviso in the special rule. According to defendant, because the Treasury Report recommended that time-barred years be excluded from global interest netting, it is unreasonable to assume that Congress concluded
Finally, defendant points to the General Explanation of Tax Legislation Enacted in 1998, prepared by the Joint Committee on Taxation, November 24, 1998 (the “Blue Book”). This court has cautioned that the Blue Book and other post-enactment explanations “are not legislative history at all.” Sharp v. United States,
III.
Because the scope of the special rule cannot be resolved by reference to the plain meaning of the statutory text, and because the legislative history behind section 6621(d) and the special rule does not clearly demonstrate Congress’s intent, we must resort to other methods of statutory interpretation. In doing so, we have found two compelling principles supporting the conclusion that the special rule applies as long as at least one of the applicable statutes of limitations remains open.
First, we take note of a long-standing rule of statutory construction: where the plain meaning of a tax statute cannot be ascertained, “the doubt must be resolved against the government and in favor of the taxpayer.” United States v. Merriam,
Second, “[w]hen interpreting ambiguous statutory tax provisions, it is appropriate to analyze other related tax provisions and seek an interpretation consistent with the tax statute viewed as an ‘organic whole.’ ” Reese v. United States,
The special rule provides that “[s]ubject to any applicable statute of limitation not having expired with regard to either a tax underpayment or a tax overpayment, the amendments made by this section [section 3301 of the 1998 Act] shall apply to periods beginning before the date of the enactment of this Act ....” Pub.L. No. 105-206, § 3301(c)(2), 112 Stat. 685, 741 (1998) (emphasis added). In other words, the special rule, by its own terms, applies section 6621(d) to past periods, and the IRS acknowledges that despite the absence of any language addressing statutes of limitations, section 6621(d) permits global interest netting for future periods as long as at least one of the relevant statutes of limitations remains open.
Defendant emphasizes the difficulty of including closed years in netting calculations. Because the IRS is now on notice as to the need to preserve tax records for netting purposes, no special statute of limitations rule is necessary. However, for past periods, where the IRS was not on notice, defendant claims that the special rule accommodates these administrative difficulties by limiting the availability of netting to open years. It may indeed be true that it is more difficult for the IRS to include pre-enactment time-barred years than post-enactment time-barred years in its calculations, but Congress appears to have accommodated this issue by placing the burden of seeking global interest netting for past periods squarely on the taxpayer, rather than on the IRS, and by setting a deadline for petitions. See Pub.L. No. 105-206, § 3301(c)(2)(A), (B),
CONCLUSION
For the reasons set forth above, plaintiff’s motion for partial summary judgment is granted and defendant’s cross-motion is denied. On or before June, 2003, the parties shall file a stipulation as to the amount due plaintiff based on this opinion.
Notes
. The Internal Revenue Code comprises Title 26 of the United States Code.
. Subchapters A and B of the Internal Revenue Code comprise the provisions relating to interest on underpayments and overpayments of tax, respectively. See I.R.C. §§ 6601, 6611.
. The Internal Revenue Code does not provide a statute of limitations for seeking the recovery of overpayment interest. Instead, a claim for additional interest allowable on a tax overpayment is subject to the six-year period provided for by 28 U.S.C. §§ 2401, 2501. See Rev. Rui. 56-506, 1956-
. A claim for credit or refund of interest paid on a tax underpayment generally must be filed within three years from the date the tax return was filed or within two years from the date on which the interest was paid, whichever expires later. See I.R.C. § 6511.
. Fannie Mae disagrees with the IRS’s conclusion that the statute of limitations for the 1983 underpayment year was closed on July 22, 1998. In view of the conclusions set forth in this opinion, this factual dispute is moot.
. From 1986 to 1998, this rule applied to corporate and individual taxpayers alike. The 1998 amendments to the Internal Revenue Code eliminated the interest differential for individual taxpayers. See I.R.C. § 6621(a)(1)(B).
. The federal short-term rate is determined by the Secretary of the Treasury pursuant to I.R.C. § 1274(d)(1)(B) and according to standards set forth in I.R.C. § 1274(d)(l)(C)(i).
. At the time of the statutory commission, Treasury and the IRS already had initiated a similar study. See IRS Announcement 96-5, 1996-
. Decisions to extend Chevron deference to revenue rulings are therefore of limited utility. See, e.g., Ammex, Inc. v. United States, No. 00-CV-73388,
. The IRS, however, did not call for comments addressing the statute of limitations issue. Rather, its request was limited to submissions "regarding the level of specificity necessary to reasonably identify and establish on or before December 31, 1999, the period(s) for which an equivalent amount of overpayment and underpayment of tax overlap when the taxpayer cannot provide by December 31, 1999/a final computation of how the net interest rate of zero applies to interest accruing before October 1, 1998.” Id.
. Defendant disagrees, arguing that the Treasury Report’s examination of the administrative difficulties presented by the inclusion of time-barred years in global interest netting calculations makes sense only if the report was assuming that pre-enactment periods would be covered by a statute authorizing global netting. But there is no basis for the assumption that statute of limitations issues simply would not have come up in a discussion of global interest netting limited to future periods. Indeed, the IRS itself, in Revenue Procedure 2000-26,
