OPINION AND ORDER
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”).
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 salе” of the LBHI bonds within the meaning of section 510(b).
II. BACKGROUND
A. Claren Road
1. Claren Road’s Claim
In December 2005, Claren Road and LBI entered into a prime brokerage agreement.
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 status
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 non-customer 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.
After LBHI’s collapse, a number of purchasers of LBHI securities filed lawsuits, including class actions, against ANZ.
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.”
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.”
III. LEGAL STANDARD
A district court functions as an appellate court in reviewing orders entered by bankruptcy courts.
IV. APPLICABLE LAW
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.
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. Howеver, 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 predicatеd 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 involven-cy[,] 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.’”
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.
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.
[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 Tele-group’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 limit*444 ing 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.”
TÍie Second Circuit considered the ambiguity of the phrase “arising from” in Med Diversified.
Rombro arg-ued 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.”
Y. 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
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.
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 оr 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.
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.
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.”
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.”
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.”
At the same time, Claren Road’s procedural argument&emdash;that it is impossible to define the relevant priorities&emdash;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.
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”&emdash; which implies a causal connection&emdash;modi-fies 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.
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
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.”
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.”
The co-underwriters argue that the risk-allocation rationale does not apply when the securities have been issued by an affiliate of the debtor.
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.
