Whether § 506(b) permits postpetition interest on an oversecured claim secured by a nonconsensual lien, such as a federal tax lien.
Holding
Yes. Section 506(b) entitles the holder of any allowed oversecured claim to postpetition interest, whether the lien arose consensually or by operation of law.
Reasoning
The Court began with the statutory text. Section 506(b) provides that an oversecured creditor may receive "interest on such claim, and any reasonable fees, costs, or charges provided for under the agreement under which such claim arose." The phrase "such claim" refers to an allowed oversecured claim, and nothing in the interest language limits that claim to one created by agreement.
The statute treats interest differently from fees, costs, and charges. Interest is separately set off by commas and followed by "and any," while the agreement requirement grammatically modifies only the later phrase concerning fees, costs, and charges. Thus, an agreement is necessary for contractual fees and similar additions, but not for postpetition interest.
This reading also fits the Code's terminology and structure. Elsewhere, Congress used the defined term "security interest" when it meant to refer specifically to a consensual lien. Section 506 generally addresses secured claims without distinguishing between consensual and nonconsensual liens, so the Court declined to add that distinction to the unqualified authorization of interest in § 506(b).
Applying the text as written did not produce an absurd result or conflict with another provision of the Code, a significant state or federal interest, or discernible legislative intent. Although postpetition interest for an oversecured creditor may reduce the assets available to other creditors, Congress itself made that allocation choice through the statute's terms.
