    Before: WALKER, JACOBS, and LIVINGSTON, Circuit Judges.
   DENNIS JACOBS, Circuit Judge:

In order to ensure that claims which are in essence claims corresponding to ownership of securities (debt or equity) are confined to their proper tier of the waterfall, Section 510(b) of the Bankruptcy Code provides generally that “a claim arising from rescission of a purchase or sale of a security of the debtor or ... for damages arising from the purchase or sale of such a security ... shall be subordinated to all claims or interests that are senior to or equal the claim or interest represented by such security....” 11 U.S.C. § 510(b). The provision treats the security of an “affiliate” as a security of the debtor for this purpose. The provision was amended in 1984 to encompass claims for contribution for such damages.

This appeal concerns the proper application of that provision in the Lehman bankruptcies. The Debtor here, Lehman Brothers Inc. (“LBI”), was lead underwriter for unsecured notes issued by Lehman Brothers Holdings Inc. (“Lehman Holdings”), its affiliate and parent. Following the bankruptcy of both the Lehman entity that issued the notes (Lehman Holdings) and the Lehman entity that was lead underwriter on the issuances (LBI), the “Junior Underwriters” were held to account for the noteholders’ losses, and incurred loss for defense and settlements. They now assert claims for contribution or reimbursement against the liquidation estate of Debtor LBI as lead underwriter of those notes.

The Bankruptcy Court of the Southern District of New York (Peck, /.) construed the statute to require subordination of the Junior Underwriters’ contribution claims. The district court (Scheindlin, J.) affirmed the bankruptcy court’s order, adopting a different analysis. We adopt the district court’s construction of § 510(b), reject the various challenges to that construction, and affirm the judgment.

BACKGROUND

On September 15, 2008, Lehman Holdings filed for Chapter 11 bankruptcy protection — the largest bankruptcy filing in U.S. history. Four days later, Lehman Holdings’s broker-dealer and wholly-owned subsidiary, LBI, was placed into liquidation pursuant to the Securities Investor Protection Act of 1970, as amended (“SIPA”), 15 U.S.C. §§ 78aaa et seq. James W. Giddens was appointed as SIPA Trustee. An automatic stay applied to both proceedings. See 11 U.S.C. § 362.

Between 2004 and 2008, before the Lehman collapse, LBI (as lead underwriter) and the Junior Underwriters launched 22 offerings of Lehman Holdings securities, totaling $32.4 billion. Beginning in December 2005, a Master Agreement Among Underwriters (the “Agreement”) governed the relationship between LBI and the Junior Underwriters. One provision of the Agreement created a right of contribution among co-underwriters (based on percentage participation) for losses or liabilities resulting from securities fraud claims arising out of the offerings.

After commencement of LBI’s SIPA proceeding (and of its parent’s Chapter 11 proceeding), investors in Lehman Holdings notes filed securities fraud lawsuits against the Junior Underwriters, alleging material misstatements and omissions in the offering documents. LBI was not a defendant due to the automatic stay. The Junior Underwriters allege that they collectively incurred almost $78 million in the defense and settlement of those claims.

The Junior Underwriters filed general creditor proofs of claim against LBI in its SIPA proceeding, asserting rights to contribution for their losses pursuant to the Agreement and Section 11(f) of the Securities Act of 1933, 15 U.S.C. § 77k(f). The SIPA Trustee objected on the ground, inter alia, that the claims were subject to mandatory subordination pursuant to 11 U.S.C. § 510(b).

The Junior Underwriters argued that § 510(b) could not be used to subordinate the claims in LBI’s SIPA proceeding because the securities were issued by LBI’s parent, rather than LBI. The Junior Underwriters acknowledge (as they must) that the section expressly applies to securities issued by “affiliate[s],” and that it requires that such claims “be subordinated to all claims or interests that are senior to or equal the claim[s] or interests] represented by such securities].... ” But they argued (and argue) that: “a ‘claim or interest represented by such security’ means ... an assertion of the rights to payment concomitant to ownership of a given security,” Br. of Appellants at 26-27; claims arising from the purchase or sale of securities of a debtor’s affiliate (and claims for contribution on account of such a claim) therefore can be subordinated in the debt- or’s bankruptcy or SIPA proceeding only when claims also could be made in that proceeding based on ownership of the affiliate’s securities; and, since the LBI estate did not independently contain securities issued by its parent, there were no “claim[s] or interest[s] represented by” the Lehman Holdings-issued securities to which the Junior Underwriters’ contribution claims could be subordinated. See id. at 5-6, 13, 26, 35-38. In other words, they argued that because the Lehman Holdings-issued securities were not otherwise part of LBI’s waterfall, § 510(b) did not apply to the Junior Underwriters’ claims.

Bankruptcy Judge Peck rejected the Junior Underwriters’ arguments and ordered their claims subordinated to the claims of general unsecured creditors. In re Lehman Bros. Inc., 503 B.R. 778 (Bankr.S.D.N.Y.2014). The bankruptcy judge reasoned that, when considering affiliate securities, the “claim[s] ... represented by” the parent securities were the claims for contribution themselves: general unsecured claims, connected in subject matter to the underlying securities. Id. at 784-85, 787.

District Judge Scheindlin affirmed the bankruptcy court’s order, but on another ground. To determine the level of subordination, the district judge focused on the type of security rather than on the type of claim. See In re Lehman Bros. Inc., 519 B.R. 434, 450 & n. 94, 451 & n. 99 (S.D.N.Y.2014). Her opinion reasoned that “any ambiguity in the statute lies not in whether claims based on securities of an affiliate are to be subordinated but how that subordination is to occur,” and that, in this instance, “[a] straightforward and practical application of section 510(b) recognizes that unsecured, non-equity securities” — like the notes at issue — “represent unsecured claims, meaning that claims involving such securities must be subordinated to general unsecured claims.” Id. at 449-51; see also id. 'at 452 (“In cases involving affiliate securities, the type of security dictates the level of subordination whether or not that security represents an actual claim in the debtor’s case.”). This appeal followed.

DISCUSSION

“We exercise plenary review over a district court’s affirmance of a bankruptcy court’s decision,” reviewing de novo the bankruptcy court’s conclusions of law, and reviewing its findings of fact for clear error. In re AppliedTheory Corp., 493 F.3d 82, 85 (2d Cir.2007) (per curiam). The facts material to the appeal are undisputed, so our review is de novo. For the following reasons, we adopt the district court’s construction of § 510(b), and affirm the judgment subordinating the Junior Underwriters’ claims.

I

Section 510(b) of the Bankruptcy Code, which applies to .this SIPA proceeding (see 15 U.S.C. § 78fff(b)), provides:

For the purpose of distribution under this title, a claim arising from rescission of a purchase or sale of a security of the debtor or of an affiliate of the debtor, for damages arising from the purchase or sale of such a security, or for reimbursement or contribution allowed under section 502 on account of such a claim, shall be subordinated to all claims or interests that are senior to or equal the claim or interest represented by such security, except that if such security is common stock, such claim has the same priority as common stock.

11 U.S.C. § 510(b) (emphases added).

The Code thus requires that the Junior Underwriters’ claims for contribution be subordinated — so long as there is a reasonable reading of § 510(b) that locates their claims on a proper tier of the Debt- or’s waterfall. The Junior Underwriters contend that no such reading is possible. We disagree.

We adopt the district court’s analysis. We hold that in the affiliate securities context, “the claim or interest represented by such security” means a claim or interest of the same type as the affiliate security. Claims arising from securities of a debtor’s affiliate should be subordinated in the debtor’s bankruptcy proceeding to all claims or interests senior or equal to claims in the bankruptcy proceeding that are of the same type as the underlying securities (generally, secured debt, unsecured debt, common stock, etc.; and in some circumstances potentially a narrower sub-category).

II

Textual principles lead us to this result. See Bustamante v. Napolitano, 582 F.3d 403, 406 (2d Cir.2009) (“Statutory analysis necessarily begins with the plain meaning of a law’s text and, absent ambiguity, will generally end there.” (alteration omitted) (quoting Puello v. BCIS, 511 F.3d 324, 327 (2d Cir.2007))). The phrase “represented by” is not self-reading and is largely unhelpful. At the same time, our construction is consistent with an ordinary meaning of the word “represent”. See Mary Jo C. v. N.Y.S. & Local Ret. Sys., 707 F.3d 144, 155 (2d Cir.2013) (“[W]e ‘review the statutory text, considering the ordinary or natural meaning of the words chosen by Congress ....’” (quoting United States v. Aguilar, 585 F.3d 652, 657 (2d Cir.2009))); 4 Collier on Bankruptcy 510.04[1] (16th ed. 2009) (“If the security is an unsecured debt instrument, the claim that is represented by that security is a general, unsecured claim.”); Webster’s Third New International Dictionary of the English Language Unabridged 1926 (1986) (defining “represent” as, inter alia, “to correspond to in kind”).

Moreover, our reading gives meaning to the entire provision, allowing the statute to operate on claims relating to affiliate securities — which are expressly included. See Samantar v. Yousuf, 560 U.S. 305, 319, 130 S.Ct. 2278, 176 L.Ed.2d 1047 (2010) (“We do not construe statutory phrases in isolation; we read statutes as a whole.” (alterations omitted) (quoting United States v. Morton, 467 U.S. 822, 828, 104 S.Ct. 2769, 81 L.Ed.2d 680 (1984))); Tablie v. Gonzales, 471 F.3d 60, 64 (2d Cir.2006) (“We are obliged ‘to give effect, if possible, to every clause and word of a statute,’ and to render none superfluous.” (alteration omitted) (quoting Collazos v. United States, 368 F.3d 190, 199 (2d Cir.2004))).

The Junior Underwriters have proposed no convincing rationale for their alternative construction, under which the affiliate securities provision would operate only in two (hypothetical) instances: when a debt- or’s and its affiliate’s estates are substantively consolidated in bankruptcy, and when the debtor had guaranteed payment on the securities of its affiliate. As a preliminary matter, nothing in the text of § 510(b) suggests the affiliate provision is so limited, and in the absence of any textual hook we hesitate to adopt a narrow construction of a section that our precedent suggests should be read “broadly.” In re Med Diversified, Inc., 461 F.3d 251, 259 (2d Cir.2006). Additionally, as the district court explained in rejecting the significance of the first hypothetical, it is “unlikely that Congress ... relied on [substantive consolidation] to provide meaning to the ‘affiliate’ language,” given that such consolidation is not provided for explicitly in the Bankruptcy Code. In re Lehman Bros. Inc., 519 B.R. at 451-52 (citing In re Augie/Restivo Baking Co., 860 F.2d 515, 518 (2d Cir.1988)).

The Junior Underwriters’ textual argument is flawed on its own terms, They contend that the district court “effectively amend[ed]” the statute. Reply Br. at 13; see also Br. of Appellants at 19. But the Junior Underwriters’ construction is no more a plain language reading than the one the district court expressed and we adopt. They would read the phrase “claim or interest represented by such security” to mean a claim or interest based on ownership of such security in this proceeding. Such language does not appear in § 510(b).

III

The available legislative history supports a construction that reaches affiliate securities in the ordinary case. Section 510(b) emerged from two distinct bills, neither of which included claims arising out of transactions in affiliate securities; they subordinated only claims arising from the purchase or sale of securities issued by the debtor. In the drafting process, Congress expressly included claims based on affiliate securities. See 11 U.S.C. § 510(b) (1982); Bankruptcy Reform Act of 1978, Pub. L. No. 95-598, § 510(b), 92 Stat. 2549, 2586 (1978). Congress further expanded § 510(b)’s reach in 1984, with the addition of claims for reimbursement and contribution. See Bankruptcy Amendments and Federal Judgeship Act of 1984, Pub. L. No. 98-353, tit. III, sec. 451, 98 Stat. 333, 375 (1984); In re Midr-Am. Waste Sys. Inc., 228 B.R. 816, 824 (Bankr. D.Del.1999) (describing 1984 amendment).

Congressional reports disclose no substantive discussion of either change. See In re Lehman Bros. Inc., 519 B.R. at 442 n. 47 (“[T]he legislative history of section 510(b) does not discuss the inclusion of affiliates in the statute.”); In re Mid-Am. Waste Sys. Inc., 228 B.R. at 824 (“Congress’s 1984 amendment to § 510(b) was not accompanied by any legislative history.”). But they were both broadening measures. And § 510(b) case law — our own and that of other courts — endorses a “broad” interpretation of the section (at least to the extent that such an interpretation is plausibly supported by the text). See, e.g., In re Med Diversified, Inc., 461 F.3d at 255, 259; In re Telegroup, Inc., 281 F.3d 133, 135-36 (3d Cir.2002); In re Betacom of Phoenix, Inc., 240 F.3d 823, 827, 830-31 (9th Cir.2001); In re Enron Corp., 341 B.R. 141, 151, 153-54, 158-59, 163 (Bankr.S.D.N.Y.2006).

IY

Just as the available legislative history supports our construction, so too does analysis of the rationales that motivated Congress to enact the section in the first place. The original enactment of § 510(b) was motivated by an influential law review article by Professors John J. Slain and Homer Kripke. In re Med Diversified, Inc., 461 F.3d at 255; see Slain & Kripke, The Interface Between Securities Regulation and Bankruptcy — Allocating the Risk of Illegal Securities Issuance Between Se-curityholders and the Issuer’s Creditors, 48 N.Y.U. L. Rev. 261 (1973). Slain and Kripke called for reinforcement of the absolute priority rule, by which creditors recover in full before equity holders recover any of their investment. Slain & Kripke, supra,- at 261. They proposed mandatory subordination in a debtor’s bankruptcy proceeding of claims alleging fraud and similar violations in the issuance of the debtor’s securities, “because the bankruptcy courts’ favorable treatment of shareholder fraud claims provided ‘investors a windfall by giving them an opportunity to reap the benefits of a profitable entity and by allowing them to share with creditors in the event the enterprise was forced to reorganize or liquidate.’ ” In re Med Diversified, Inc., 461 F.3d at 256 (quoting In re PT-1 Commc’ns, Inc., 304 B.R. 601, 609 (Bankr.E.D.N.Y.2004)).

Slain and Kripke’s article gave two related policy rationales for subordination: “(1) the dissimilar risk and return expectation of shareholders and creditors,” referred to as the “risk-allocation rationale”; and “(2) the reliance of creditors on the equity cushion provided by shareholder investment,” referred to as the “equity cushion rationale.” Id. at 256, 259; see Slain & Kripke, supra, at 286-91. Congress generally adopted the Slain and Kripke rationales when enacting § 510(b), which incorporated much (though not all) of the proposal advanced in their article. See In re Med Diversified, Inc., 461 F.3d at 255-56; In re Telegroup, Inc., 281 F.3d at 139; H. Rep. No. 95-595, at 194 (1977), 1978 U.S.C.C.A.N. 5963, 6154 (“The argument for mandatory subordination is best described by Professors Slain and Kripke.”); id. at 194-96 (summarizing and adopting their argument).

The risk-allocation rationale is “ ‘more integral to any policy analysis of section 510(b)’” than is “the equity cushion concept,” the latter being “ ‘only one part of the broader judgment concerning risk allocation.’ ” In re Med Diversified, Inc., 461 F.3d at 258-59 (quoting In re Enron Corp., 341 B.R. at 166); see also In re Telegroup, Inc., 281 F.3d at 139 (noting that Slain and Kripke “coneeptualiz[ed] the issue as one of risk allocation”); Slain & Kripke, supra, at 263; id. at 267 (“We are only incidentally concerned with the precise predicate of a disaffected stockholder’s efforts to recapture his investment from the corporation.”). Risk allocation serves as an effective rationalization for subordination in those circumstances when an affiliate’s securities provide the basis for the claim, because the purchasers of the securities issued by the affiliate have taken -on the risk-return expectations of investors while the debtor’s creditors have not. See In re Med Diversified, Inc., 461 F.3d at 258-59. Moreover, we need not determine whether this rationale is strong enough to warrant subordination of claims arising out of transactions in affiliate securities — Congress has already determined that it is. See 11 U.S.C. § 510(b).

“Congress enacted § 510(b) to prevent disappointed shareholders from recovering their investment loss by using fraud and other securities claims to bootstrap their way to parity with general unsecured creditors in a bankruptcy proceeding.” In re Enron Corp., 341 B.R. at 158. In order to prevent such bootstrapping from being effected indirectly, the statute likewise subordinates claims for contribution and reimbursement based on payments made to disappointed investors.

V

Every other court that has applied § 510(b) to claims based on affiliate securities — when the debtor was a corporate entity' — has required subordination. However, a survey of these cases provides little guidance in determining the appropriate level of subordination. They come out diverse ways; many do not discuss the issue explicitly; some that do give no reasons; and none involves a claimant making the same type of textual argument that the Junior Underwriters present here. But they nevertheless provide ballast for an interpretation of the statutory text that reaches affiliate claims in the ordinary case.

VI

When a bankruptcy court subordinates claims arising out of securities that were issued by the debtor’s affiliate, it may become somewhat messy to superimpose the capital structure of the affiliate onto that of the debtor (although this case may not require the bankruptcy court to confront these issues). Nevertheless, our approach works in broad strokes, and preserves flexibility needed by the bankruptcy court.

The bankruptcy court will be guided by the instruction that claims arising from securities of a debtor’s affiliate are to be subordinated to all claims or interests senior or equal to claims in the bankruptcy proceeding that are of the same type as the underlying securities (generally, secured debt,'unsecured debt, common stock, etc.). The bankruptcy court is well-suited to engage in that kind of classification and discrimination. A court of equity may also determine whether it makes sense to group claims for subordination into narrower sub-categories. When granular distinctions of priority among the affiliate’s securities are not mirrored in the debtor’s 'estate, a bankruptcy court may have to add tiers to the waterfall or, in a different case, may have to group multiple levels of priority. Similar choices are made in Chapter 11 reorganizations, in which bankruptcy judges determine whether securities are “substantially similar” to other securities such that they should be classified together. See 11 U.S.C. § 1122 (providing that a debtor’s reorganization plan “may place a claim or 'an interest in a particular class only if such claim or interest is substantially similar to the other claims or interests of such class”).

Bankruptcy judges regularly make these types of determinations, and they are better situated to do so than we are.

CONCLUSION

For the foregoing reasons, we AFFIRM the judgment of the district court.

      . Collier was not referencing claims arising out of affiliate securities, and the observation would be non-controversial in the non-affiliate context.
     
      
      . Various constructions have been advanced to give effect to the "affiliate” language. Our construction is preferable to the competing constructions advanced in this litigation. The bankruptcy court’s approach is less plausible as a textual matter: Section 510(b) directs subordination to "claims or interests that are senior to or equal the claim or interest represented by such security,” not to the claim or interest represented by such claim. The Trustee’s alternative approach — to which he devotes a single paragraph of his appellate brief — asks the bankruptcy court to assume that LBI was liable on its parent's securities and to subordinate the contribution claims below those phantom liabilities (disregarding their separate corporate forms). Furthermore, the Trustee appears to imagine that such phantom claims (based on ownership of the parent’s securities) would be situated at the very bottom of LBI's waterfall — below even the claims based on ownership of LBI common stock. Such a super-subordination seems inconsistent with the directive that no claims are to be subordinated below the level of the debtor's common stock. See 11 U.S.C. § 510(b).
     
      
      . As relevant here, both proposed bills subordinated "any claim for rescission of the purchase of securities issued by the debtor corporation or for damages resulting from the purchase or sale of such securities.” See Bankruptcy Act Revision, Hearings on H.R. 31 and H.R. 32 Before the Subcommittee on Civil & Constitutional Rights of the H. Comm, on the Judiciary, 94th Cong. 27, App'x 1 at 1, 142, App’x 2 at 355 (1976) (proposed 1975 bankruptcy acts).
     
      
      . These cases concerned the types of claims eligible for subordination by virtue of falling within the first half of § 510(b) (referred to as "arising-from” claims).
     
      
      . Slain and Kripke did not propose subordinating claims arising from the purchase or sale of securities of the debtor's affiliate, and therefore had no occasion to consider how or whether the rationales they offered might bear upon the subordination of such securities. See generally Slain & Kripke, supra.
      
     
      
      . Several courts have concluded that the reimbursement and contribution amendment was a "logical extension” of the original risk-allocation rationale, and that Congress intended to ensure that the "risks associated with the issuance of stock [and securities]” were placed on the "underwriter, who is in a better position to evaluate such risks,” and were not shifted to general unsecured creditors. In re Mid-Am. Waste Sys., Inc., 228 B.R. at 825-26, 828; see also, e.g., In re Ja-com Comput. Servs., Inc., 280 B.R. 570, 572 (Bankr.S.D.N.Y.2002); In re Walnut Equip. Leasing Co., No. 97-19699(DWS), 1999 WL 1271762, at *9-10 (Bankr.E.D.Pa. Dec. 28, 1999).
      In the bankruptcy court, the Junior Underwriters acknowledged that a “debtor's underwriters are better positioned to manage [the risk of the debtor's failure] than its creditors.” J.A. 182 ¶ 34 (Resp. Of Underwriter Claimants to the Trustee’s One Hundred Fourth Omnibus Objection to General Creditor Claims). They now argue, however, that the rationale of these cases is “dubious,” and that "in any event, it only holds for the issuer's creditors since it focuses solely on which parties — the issuer's underwriters or the issuer’s creditors — were better positioned to protect themselves from the issuer’s wrongful conduct.” Br. of Appellants at 32-33. If a policy judgment on this point were required to resolve this case, we might find that, as between the Junior Underwriters and LBI’s general creditors — which had no involvement in the issuance of securities of LBI’s parent — the Junior Underwriters were likely better situated to anticipate and manage the risk of material misstatements or omissions in the Lehman Holdings offering materials. See Chris-Craft Indus. Inc. v. Piper Aircraft Corp., 480 F.2d 341, 370 (2d Cir.1973) (noting underwriters’ "expertise in appraising the securities issue and the issuer” and their "special motive thoroughly . to investigate the issuer’s strengths and weaknesses”). But we need not make such a finding; Congress explicitly included claims for contribution on account of damages claims arising from the securities of a debtor's affiliate in § 510(b).
     
      
      . See, e.g., In re Am. Hous. Found., 785 F.3d 143 (5th Cir.2015); In re VF Brands, Inc., 275 B.R. 725 (Bankr.D.Del.2002); In re Lemout & Hauspie Speech Prods., N.V., 264 B.R. 336 (Bankr.D.Del.2001); In re Basin Res.

Nov. 18, 2013) (same result in individual debtor case).
     
      
      . LBI’s SIPA liquidation has a single class of general unsecured creditor claims; and it appears that these claims are expected to consume the LBI estate. See Br. for Appellee at 30-31; cf. Reply Br. at 10.
     
      
      . The one case on which the Junior Underwriters rely, In re Khan, 523 B.R. 175 (9th Cir. BAP 2014) (declining to apply the statute to claims relating to affiliate securities in the bankruptcy proceeding of two individual debtors), is easily distinguishable. The rationale of the court (which did not parse the meaning of "represented by”) was focused entirely on whether the statute applies to an individual (non-corporate) debtor. See id. at 182-83. It found the text to be ambiguous on this question, and ultimately determined that § 510(b) does not apply to an individual debt- or, because the policy rationales behind it are inapt: An individual debtor's creditors do not rely on any equity cushion when determining whether to extend credit, and the two different levels of risk-return expectations do not exist. Id. at 183.
