OPINION AND ORDER
SHIRA A. SCHEINDLIN, District Judge.
I. INTRODUCTION
On September 19, 2008, Lehman Brothers Inc. ("LBI"), a registered broker-dealer and wholly-owned subsidiary of Lehman Brothers Holdings Inc. ("LBHI"), was placed into liquidation pursuant to the Securities Investor Protection Act of 1970 ("SIPA"), and James W. Giddens was appointed as SIPA trustee (the "Trustee"). Before the Court are three related appeals from two orders entered by Bankruptcy Judge James M. Peck in LBI's SIPA proceeding (the "Orders").1 In relevant part, the Orders grant a motion and sustain an objection filed by the Trustee seeking to subordinate certain claims pursuant to section 510(b) of the Bankruptcy Code. The Bankruptcy Court found that subordination of the claims to the claims of general unsecured creditors was mandated under the plain language of section 510(b).
Appellant Claren Road Credit Master Fund Ltd. ("Claren Road") argues that its claim for damages against LBI, based on LBI's failure to purchase bonds issued by LBHI from Claren Road pursuant to a prime brokerage account agreement, should not be subordinated because it does not "aris[e] from the purchase or sale" of the LBHI bonds within the meaning of section 510(b).2 In addition, Claren Road and the remaining appellants, co-underwriters3 with LBI in the issuance of LBHI securities, argue that section 510(b) is inapplicable because there are no claims or interests "represented by" LBHI securities in LBI's SIPA proceeding.4 For the reasons set forth below, the Orders are AFFIRMED.
II. BACKGROUND
A. Claren Road
1. Claren Road's Claim
In December 2005, Claren Road and LBI entered into a prime brokerage agreement.5 The PBA deems LBHI and certain LBHI affiliates as parties and is signed by LBI "as signatory for itself and as agent for the affiliates named herein."6 As prime broker, LBI agreed to "`settl[e] trades executed on [Claren Road's] behalf by [its] executing broker(s).'"7 On September 12, 2008, LBI and Claren Road entered into two separate trades in which LBI agreed to purchase LBHI bonds from Claren Road at a discount to par. LBI breached its agreement to purchase the LBHI bonds on September 17, 2008, when it failed to settle the trades. Claren Road filed a claim against LBI in the SIPA liquidation for over $8.5 million, representing the difference between the amount that LBI had agreed to pay for the LBHI bonds and their market price on September 19, 2008.8
2. The Trustee's Motion and the Bankruptcy Court's Order
On October 25, 2013, the Trustee filed a motion seeking to confirm the non-customer status9 of Claren Road's claim under SIPA and to subordinate it to the claims of general unsecured creditors pursuant to section 510(b).10 Claren Road argued that on a literal reading of section 510(b), its claim does not arise from a purchase or sale of a security because LBI did not complete the purchase of the LBHI bonds.11 It further argued that under Second Circuit Case law, section 510(b) is ambiguous when applied to its claim and that subordination of its claim would not further the policy objectives underlying the statute.12 The Bankruptcy Court held that under the plain language of the statute, Claren Road's claim was subject to subordination as a claim arising from the purchase or sale of a security of a debtor affiliate.13 The Bankruptcy Court also rejected Claren Road's argument that because section 510(b) states that an arising from claim "shall be subordinated to all claims or interests that are senior to or equal the claim or interest represented by such security," claims based on LBHI bonds may not be subordinated in LBI's SIPA proceeding where holders of LBHI bonds have no claims against LBI's estate.14 The Bankruptcy Court explained that
Claren Road's approach is too narrow and fails to recognize the common meaning of the words used in the statute. A more reasonable interpretation of the statutory language is that the "claim ... represented by [the LBHI Bonds]" is not directed to a recovery from LBI on account of the LBHI Bonds but extends to the breach of contract claim asserted by Claren Road against LBI with respect to these bonds. Such a claim is a general unsecured claim that is connected to the subject matter of the securities in question. The essence of the claim is the failure to purchase the LBHI Bonds. This reading of the plain language of the statute leads to the conclusion that the Claren Road Claim "shall be subordinated to all claims ... that are senior to or equal" the general unsecured claims against LBI.
Interpreting the phrase "claim or interest represented by such security" in this fashion is a common sense interpretation of section 510(b) that infuses the words of section 510(b) with meaning. If a claim "represented by such security" were to be restricted to a recovery from the issuer for amounts outstanding under the security, then no claim arising from the purchase or sale of affiliate securities would ever fit within the regime for subordination. Such a result would contradict express provisions of the statute which direct that such claims shall be subordinated.15
The Bankruptcy Court entered an order allowing Claren Road's claim as a noncustomer claim in its asserted amount, and subordinated that claim to the claims of general unsecured creditors.
B. The Co-underwriters
1. ANZ
In the course of its business as a broker-dealer, LBI served as lead underwriter in connection with offerings of registered securities issued by LBHI.16 LBI and ANZ entered into a Master Agreement Among Underwriters dated December 1, 2005, which governed the relationship among the underwriters.17 "The agreement required each underwriter to contribute, based on its agreed percentage participation in an offering, toward losses or liabilities incurred by another underwriter arising from allegations that the offering materials contained untrue statements or omissions."18
After LBHI's collapse, a number of purchasers of LBHI securities filed lawsuits, including class actions, against ANZ.19 LBI was not named as a defendant because of the bar created by the automatic stay under section 362. These actions alleged that LBHI's offering documents contained material misstatements and omissions and sought to hold ANZ liable for damages under federal securities laws.20 ANZ's legal fees and settlement payments came to nearly seventy-eight million dollars and ANZ filed claims in LBI's SIPA proceeding based on asserted contractual and statutory rights to contribution.
2. UBSFS
Pursuant to a purchase agreement entered into by UBSFS and LBI in 2007, "[i]n 2007 and 2008, UBSFS purchased from LBI, in LBFs capacity as underwriter, certain notes, including certain Medium Term Notes, Series I, U.S. Structured Notes issued by LBI [], expressly earmarked for sale to UBSFS clients."21 There were approximately eighty-four issuances of the LBHI notes pursuant to the parties' agreements. UBSFS did not purchase or hold any of the notes for its own account.22 Following the commencement of LBI's SIPA case, a number of UBSFS clients filed class action lawsuits or initiated arbitration proceedings against UBSFS, asserting securities fraud and related claims based on alleged material misstatements and omissions in the offering materials concerning the LBHI notes.23 UBSFS filed a claim for over two hundred and fifty million dollars based on its statutory right to contribution.24
3. The Trustee's Objection and the Bankruptcy Court's Order
On July 12, 2013, the SIPA Trustee filed an objection to the underwriter claims arguing that such claims should be subordinated under section 510(b). The co-underwriters argued that their claims could not be subordinated "because the LBHI securities do not represent a claim that can be made in the LBI case."25 The Bankruptcy Court rejected the co-underwriters' "hyper-technical" focus "on what it means for claims to be represented by securities of an affiliate of the debtor," disagreeing that "the claims must be based on securities within the capital structure of an enterprise that includes a debtor and affiliated entities."26 The Bankruptcy Court explained that this rested on "the false premise [] that the claims represented by the securities of an affiliate of the debtor must be the same kinds of claims that could be made by a holder of those securities against that affiliate" and concluded that the co-underwriters' claims "are simply claims for reimbursement and contribution based on the sale of securities of LBHI, an affiliate of the debtor, and such claims do not rank equally with other unsecured claims against LBI.27 In reaching this conclusion, the Bankruptcy Court relied on the plain language of the statute and therefore did not consider legislative history or any other external material.
III. LEGAL STANDARD
A district court functions as an appellate court in reviewing orders entered by bankruptcy courts.28 Findings of fact are reviewed for clear error,29 whereas findings that involve questions of law, or mixed questions of fact and law, are reviewed de novo.30 A district court "may affirm, modify, or reverse a bankruptcy judge's judgment, order, or decree or remand with instructions for further proceedings."31
IV. APPLICABLE LAW32
Section 510(b), as amended in 1984, provides that
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.33
Section 510(b) thus describes three categories of claims that are subject to mandatory subordination and then addresses how subordination is to occur.34 The two categories relevant here are claims (i) "for damages arising from the purchase or sale of [a security of the debtor or of an affiliate of the debtor]" and (ii) "for reimbursement or contribution ... on account of such a claim[.]"35 With regard to the level of subordination, a leading treatise describes the operation of section 510(b) as follows:
A shareholder claimant who seeks to rescind an equity interest and to obtain a debt claim will have the debt claim subordinated. Rescission will lead to subordination below the interest held before rescission. However, if the security is common stock, the claim has the same priority as common stock. If the security is an unsecured debt instrument, the claim that is represented by that security is a general, unsecured claim. Since the claim represented by the instrument is a general, unsecured claim, any claim for rescission will be subordinated until the claims of the general unsecured creditors have been satisfied.36
A report of the United States House of Representatives sheds light on the purpose of section 510(b):
A difficult policy question to be resolved in a business bankruptcy concerns the relative status of a security holder who seeks to rescind his purchase of securities or to sue for damages based on such a purchase: Should he be treated as a general unsecured creditor based on his tort claim for rescission, or should his claim be subordinated? ... [Professors Slain and Kripke] conclude that allocation of assets in a bankruptcy case is a zero-sum situation, and that rules of allocation in bankruptcy should be predicated on allocation of risk. The two risks to be considered are the risk of insolvency of the debtor and the risk of an unlawful issuance of securities. While both security holders and general creditors assume the risk of involvency[,] Slain and Kripke conclude that the risk of illegality in securities issuance should be borne by those investing in securities and not by general creditors.37
As explained by the Second Circuit in Med Diversified, "Congress ... adopted Slain and Kripke's policy rationales for mandatory subordination: `1) the dissimilar risk and return expectations of shareholders and creditors; and 2) the reliance of creditors on the equity cushion provided by shareholder investment.'"38 Either rationale can justify subordination under section 510(b), but courts have focused mainly on the risk-allocation rationale.39 The risk-allocation rationale "represents a Congressional judgment that, as between shareholders and general unsecured creditors, it is shareholders who should bear the risk of illegality in the issuance of stock in the event the issuer enters bankruptcy."40
Notably, this statement concerning the risk-allocation rationale is incomplete for two reasons. First, as recognized in Med Diversified, section 510(b) is not limited to claims based on fraud in the issuance.41 Indeed, Slain and Kripke were "only incidentally concerned with the precise predicate of a disaffected shareholder's efforts to recapture his investment from the corporation."42 Second, section 510(b) is not limited to shareholder claims.43 Section 510(b) uses the term "security," which is defined in section 101(49) of the Bankruptcy Code as including stocks, bonds, and notes, among other instruments. Accordingly, section 510(b) has been applied broadly to subordinate claims arising in a variety of contexts, such as claims based on fraudulent retention,44 as well as other torts or breach of contract claims involving the failure to deliver, exchange, or register securities.45 Courts have also subordinated claims for contribution, indemnification, and reimbursement asserted by underwriters and others,46 and claims based on securities of an affiliate of the debtor.47 Courts also recognize that the claimant need not be an actual security holder,48 and the debtor need not be the issuer of the security for section 510(b) to apply.49
In a number of differing contexts, courts have found the phrase "arising from the purchase or sale of a security" to be ambiguous. The source of this ambiguity is typically the terms "arising from," which imply a causal connection.50 For example, in Telegroup, parties to a stock purchase agreement that required the seller to use its best efforts to register the stock brought a claim based on the theory that had the seller registered the stock, they would have sold their shares and avoided their losses.51 The Third Circuit deemed section 510(b) ambiguous in this context, and explained that
[f]or a claim to "aris[e] from the purchase or sale of ... a security," there must obviously be some nexus or causal relationship between the claim and the sale of the security, but § 510(b)'s language alone provides little guidance in delineating the precise scope of the required nexus. On the one hand, it is reasonable, as a textual matter, to hold that the claims in this case do not "arise from" the purchase or sale of Telegroup's stock, since the claims are predicated on conduct that occurred after the stock was purchased. On the other hand, it is, in our view, more natural, as a textual matter, to read "arising from" as requiring some nexus or causal relationship between the claims and the purchase of the securities, but not as limiting the nexus to claims alleging illegality in the purchase itself.52
In the Third Circuit's view, section 510(b) "is reasonably read to encompass" claims based on the failure to register securities, as they "would not have arisen but for the purchase of Telegroup's stock and allege a breach of a provision of the stock purchase agreement."53
The Second Circuit considered the ambiguity of the phrase "arising from" in Med Diversified.54 In that case, a departing employee, David Rombro, entered into a severance agreement whereby Med Diversified agreed to issue shares of its common stock to Rombro in exchange for Rombro's shares in PrimeRX, an unaffiliated company.55 After Med Diversified filed for bankruptcy protection, Rombro asserted a claim based on its failure to consummate the exchange. Relying on "Case law broadly construing section 510(b)," the bankruptcy court determined "that the claim need not flow directly from the securities transaction, but can be viewed as `arising from' the transaction if the transaction is part of the causal link leading to the injury."56
Rombro argued on appeal that "the phrase `arising from' in section 510(b) is unambiguous and plainly applies only to claims stemming directly from a purchase, sale, or rescission of the debtor's security, none of which occurred here."57 According to Rombro, "his claim did not arise from damages flowing from the purchase or sale of debtor's stock but from the purchase by the debtor of Rombro's PrimeRx stock, which in any event never occurred."58 The Trustee argued that "claims `arising from' the purchase of a security ... include claims that are predicated on the failure to issue stock, relying on Case law broadly interpreting the statute."59 Although the Second Circuit found section 510(b) to be ambiguous, it nonetheless held that Rombro's claim arose from the purchase or sale of a security of the debtor in large part because once Rombro entered into the stock exchange agreement "he became bound by the choice he made to trade the relative safety of cash compensation for the upside potential of shareholder status — the very choice highlighted by Slain and Kripke."60
V. DISCUSSION
A. The Bankruptcy Court Did Not Err in Subordinating Claren Road's Claim
Claren Road argues that the Bankruptcy Court erred in finding that section 510(b) was unambiguous when applied to its claim.61 While Claren Road suggests that on a literal reading section 510(b) does not apply in the absence of an actual purchase or sale, it stresses that the Second Circuit deemed the statute to be ambiguous under a "similar factual scenario in Med Diversified."62 Thus, Claren Road argues that the Bankruptcy Court was obligated to consider section 510(b)'s legislative history and purpose to resolve this ambiguity, and, that if it had, it would have recognized that subordination of Claren Road's claim did not advance the statute's purpose.63
Claren Road argues that section 510(b) is squarely aimed at investors that attempt to bootstrap their way to parity with unsecured creditors by transforming their investment interests into unsecured claims.64 According to Claren Road, subordination of its claim does not further either the risk-allocation or equity-cushion policy rationales identified in Med Diversified as the only two policy rationales justifying subordination.65 This is because Claren Road did not "assume the risk or return expectations of a Lehman investor, much less an LBI equity holder" insofar as its claim arises from an attempt to dispose of the bonds for "a fixed sum of cash."66 In addition, Claren Road warns that "[a]llocating the risk associated with a prime-broker's insolvency to the broker's customers will have a negative impact on the prime-brokerage industry," because customers, who cannot easily identify whether a security has been issued by an affiliate of a broker-dealer, will refuse to do business with financially troubled broker-dealers for fear their claims will be subordinated under section 510(b), leading to more broker-dealer failures.67
The Bankruptcy Court did not err in holding that Claren Road's claim was subject to subordination under section 510(b). First, even if the statute were ambiguous as to whether an "actual" purchase or sale is needed, under Med Diversified and other Case law it is now well-settled that section 510(b) applies in the absence of an actual purchase or sale.68 Indeed, in Med Diversified the Second Circuit was "influenced by what appears to be the uniform determination of courts presented with similar claims" that section 510(b) mandated subordination even in the absence of a purchase or sale.69 As discussed below, the fact that Rombro bargained to buy securities and Claren Road was attempting to sell securities does not immunize Claren Road's claim from subordination. In short, given "[t]he weight of precedent favoring subordination" even where no purchase or sale has occurred, "and the absence of persuasive precedent upholding the contrary position, the ambiguity vel non of the statutory text" is beside the point.70
Second, applying the statute to Claren Road's claim does not require "arising from" to be read nearly as broadly as permitted under the Case law.71 For example, unlike Rombro in Med Diversified, Claren Road held the LBHI bonds and was attempting to sell them, and the failure of that sale was a direct cause of Claren Road's damages.72 For another example, even though causal ambiguity weighs less heavily for Claren Road's claim than for claims under a fraudulent retention theory, Claren Road's failed attempt to dispose of the bonds is the functional equivalent of the fraudulent retention claims subordinated in cases like Geneva Steel, Granite Partners, Enron, and Motor Liquidation. Indeed, regardless of the type of claim, precedent requires subordination of claims by security holders that seek to recover, as Claren Road does, for the loss in value of a security issued by the debtor or an affiliate. Neither section 510(b) nor SIPA suggests an exception for transactions involving broker-dealer debtors either purchasing or selling affiliate bonds. SIPA provides that section 510(b) applies in liquidation proceedings;73 bonds, in keeping with their common meaning, are included in the definition of security;74 and section 510(b) explicitly references both debtor and debtor-affiliate securities.75
Finally, the risk-allocation policy rationale supports subordination of Claren Road's claim. As the putative seller of LBHI bonds, there is no doubt that Claren Road was an LBHI bondholder.76 The elephant in the room is that Claren Road entered into its agreement with LBI on Friday, September 12, 2008, and as is well known, on Monday September 15, 2008, LBHI and certain of its affiliates filed petitions for relief under chapter 11 of the Bankruptcy Code, followed days later by LBI's SIPA proceeding.77 But Claren Road's motivation for selling the bonds is beside the point — "Just as the opportunity to sell or hold belong exclusively to the investors, the risk of illegal deprivations of that opportunity should too."78 Whether by holding an interest in the LBHI bonds or by entering into the agreement to have LBI purchase those bonds, Claren Road assumed the risk of exactly what happened here — the loss of its investment.79 Claren Road argues that the risk-allocation rationale does not apply because LBI agreed to pay a fixed sum of cash for the LBHI bonds, and that "in contrast to Med Diversified, where the claimant contracted to acquire more stock, Claren Road sought to dispose of the LBHI Bonds, thereby terminating its right to share in any appreciation in price."80 However, Claren Road still held the LBHI bonds as of the petition date, and its claim is based in part on the diminished value of those bonds.81 Furthermore, the distinction drawn by Claren Road between Rombro's attempt to acquire securities in Med Diversified and Claren Road's attempt to divest its interest in securities is legally irrelevant.82 "The fact that the value of the [bonds] declined while [Claren Road] held them... should not enable [Claren Road] to eviscerate the absolute priority rule, and shift to creditors the investment risk assumed by the [bond] holders."83 In short, subordination of Claren Road's claim pursuant to section 510(b) is justified because it prevents Claren Road from converting its investment loss into a creditor claim.84
B. The Bankruptcy Court Did Not Err in Subordinating Appellants' Claims to the Claims of General Unsecured Creditors
1. Claren Road
Claren Road argues that the "language directing subordination of the asserted claim to claims or interests `represented by such security' makes no sense where the applicable security creates no claim on the debtor's estate."85 According to Claren Road, its claim "and claims `represented by' LBHI Bonds simply do not exist in the same priority chain."86 Claren Road thus contends that "[a]s written, section 510(b) offers no guidance regarding its application when the debtor and the issuer of the subject security are separate entities" and therefore the phrase "represented by such security" is ambiguous when applied to a claim arising from securities of an affiliate.87 In support of this point, Claren Road argues that "[f]our separate interpretations of the phrase were put forward in this case alone, including two articulated by the Bankruptcy Court."88 Claren Road's interpretation was that the language refers to the underlying security and that subordination is proper only when there is a close nexus between the affiliate security and the asserted claim, "such as when the debtor has guaranteed the security in question or entered into an agreement to deliver to a creditor the debtor's subsidiary's securities in full satisfaction of a debt...."89
The Trustee, in turn, argued that "because the LBHI Bonds have `no valid interests' against LBI, the Claren Road Claim must be subordinated to zero."90 At the hearing on the claim objection, the Bankruptcy Court suggested a "virtual security" where one assumes that the security of an affiliate is the security of the debtor. Finally, Claren Road argues that the Bankruptcy Court "rejected all of these approaches" and found that a claim represented by the LBHI bonds includes "all claims with respect to or connected to the subject matter of the LBHI Bonds."91 Thus, Claren Road argues that the Bankruptcy Court erred by not considering the legislative history and purpose of section 510(b), and that subordination of a claim based on securities issued by an affiliate is proper only when such subordination furthers either the risk-allocation or equity-cushion rationales identified in Med Diversified.92 As discussed earlier, Claren Road argues that neither rationale applies.
However, the statute directs that Claren Road's claim "for damages arising from the purchase or sale of [the LBHI bonds]" be subordinated for purposes of distribution to "all claims or interests that are senior to or equal the claim or interest represented by [the LBHI bonds.]" In other words, the statute separately refers to the claim subject to subordination, the underlying debtor or affiliate security, and the claim or interest represented by that security.
But nothing in section 510(b) ties subordination to a security within the capital structure of the debtor. Claren Road's argument to the contrary simply assumes that this must be the case because otherwise the claim to be subordinated and the claim represented by the security would not be in the same priority scheme which, Claren Road argues, makes it impossible to define the level of subordination. Claren Road's substantive argument — that the security must exist within the capital structure of the debtor — is not only unsupported by the plain language of the statute, but contradicted by the statute's inclusion of affiliate securities.
This is not to say that Claren Road's assumption about the priority scheme is implausible. As one court notes, "[i]t is true that generally shareholders of a subsidiary have no claim against the parent and thus are not part of any priority scheme of claims against the parent."93 However, section 510(b) unambiguously states that rescission, arising-from, and contribution claims involving securities of an affiliate of the debtor are subject to subordination. Thus, 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. For this reason, Claren Road's assumption about the priority structure is untenable as it would automatically exclude claims arising from the purchase or sale of securities of an affiliate in derogation of the plain language of the statute.
At the same time, Claren Road's procedural argument — that it is impossible to define the relevant priorities — is easily overcome. Under section 510(b), Claren Road's claim is a claim based on LBI's breach, the securities involved in that claim are the LBHI bonds, and because the LBHI bonds are unsecured debt instruments, the most natural way to read section 510(b) is that the claim "represented by" such unsecured debt instruments is an unsecured claim. Accordingly, Claren Road's claim is properly subordinated to claims of unsecured creditors.94 This focus on the type of claim the security represents, rather than where the security falls in the capital structure of the debtor, promotes the purpose of section 510(b), which is to ensure that creditors receive their distribution ahead of investors. By contrast, Claren Road places greater importance on the structure of the priority scheme than the requirement of subordinating certain types of claims for the benefit of creditors.
In addition, it is not reasonable to read section 510(b) as applying only when there is a close nexus between the affiliate security and the asserted claim. Section 510(b) states that a claim "arising from the purchase or sale of" a security of a debtor or an affiliate of the debtor "shall be subordinated to all claims or interests that are senior to or equal the claim or interest represented by such security...." The statute's application to securities of an affiliate is therefore unambiguous. Furthermore, the phrase "arising from" — which implies a causal connection — modifies the types of claims that are subject to mandatory subordination, not how those claims are to be subordinated. Neither the phrase "represented by" nor its placement in section 510(b) implies a causal connection requiring a close nexus between the security and the asserted claim.95 Finally, for the reasons discussed above, subordination of Claren Road's claim fits within the purpose of section 510(b). After all, had Claren Road not entered into the transaction with LBI involving LBHI bonds, it would not have a claim against LBI relating to the diminished value of the LBHI bonds at all (although it would still have a claim against LBHI). Section 510(b) prevents Claren Road from collecting pari passu with LBFs general unsecured creditors by virtue of its failed attempt to sell the LBHI bonds.
2. The Co-Underwriters
The co-underwriters concede that their claims are for contribution within the meaning of the first portion of section 510(b). They argue that claims "represented by" LBHI securities must mean claims that are based on ownership of LBHI securities. They then argue that because LBHI securities "do not represent a claim that can be made in the LBI case" there are no claims in LBI's case to which their claims can be subordinated.96 Alternatively, the co-underwriters argue that subordination of their claims does not serve the purposes behind section 510(b).97
As explained by the Bankruptcy Court, the co-underwriters' "strained argument... assumes that the claims must be based on securities within the capital structure of an enterprise that includes a debtor and its affiliated securities."98 However, as discussed in connection with the Claren Road claim, that assumption is not supported by the statutory text. A straightforward and practical application of section 510(b) recognizes that unsecured, non-equity securities represent unsecured claims, meaning that claims involving such securities must be subordinated to general unsecured claims, and when the relevant security is common stock the underlying claim is subordinated to the level of common stock.99
As one court notes, when a "provision such as section 510(b) [] plainly incorporates a broad standard," textual analysis "has a tendency to miss the forest for the trees."100 The co-underwriters' arguments seize on the opportunity to parse section 510(b) in the relatively untested context of the treatment of claims based on securities issued by an affiliate of the debtor in a SIPA liquidation. What is lost in this effort is that there is no question that their claims would be subordinated to the claims of general unsecured creditors if they were based on LBI securities in the SIPA proceeding or LBHI securities in LBHI's bankruptcy case. In either scenario, the precise meaning of "represented by" would not be relevant to the issue of subordination.101 Because claims for contribution arising from transactions based on securities of an affiliate of the debtor are plainly subject to subordination under section 510(b), it would be anomalous to restrict section 510(b)'s application to the rare contexts suggested by the co-underwriters.102 For example, the Bankruptcy Code does not expressly provide for substantive consolidation, making it unlikely that Congress would have relied on that mechanism to provide meaning to the "affiliate" language in section 510(b).103
The co-underwriters argue that the risk-allocation rationale does not apply when the securities have been issued by an affiliate of the debtor.104 But by including securities of affiliates in section 510(b), Congress has already made the judgment that claims for contribution based on such securities must be subordinated. This is because "underwriters are in a better position to allocate risks associated with the issuance of securities and [] it is inconsistent with the policies articulated in the legislative history of section 510(b) to force unsecured creditors to subsidize the underwriters' litigation costs."105
VI. CONCLUSION
In sum, section 510(b) mandates the subordination of arising-from and contribution claims, provided such claims are based on securities of a debtor or an affiliate of the debtor. The level of subordination can be determined by reference to the type of claim or interest represented by such security — e.g., secured, unsecured, common stock, or equity. 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. For the foregoing reasons, the two Orders entered by the Bankruptcy Court are AFFIRMED. The Clerk of the Court is directed to close these appeals.
SO ORDERED.
