Debtors’ counsel often assume that a borrower’s insolvency gives them meaningful leverage to challenge an oversecured lender’s claim for postpetition default interest under Section 506(b) of the Bankruptcy Code. Judge Philip Bentley’s recent bench decision in In re 33 Mako, LLC challenges that assumption. This opinion clarifies how courts in the Second Circuit apply the five-factor framework in determining whether the default rate should be allowed and what “harm to creditors” really means.
Background: A Hamptons Foreclosure: 33 Mako, a single-asset real estate debtor, defaulted on a $2.4 million hard-money loan secured by a Hamptons residence. The lender, SCL Funding, sought $516,000 in default interest at a contractual 16% rate. The debtor filed Chapter 11 to stop a foreclosure, with the property ultimately selling for $4.32 million. After paying the lender, administrative claims, and a modest $7,000 in non-insider unsecured claims, only the debtor’s insiders (entities controlled by 33 Mako’s principal) stood to lose if default interest were allowed.
The Second Circuit’s Five-Factor Framework: Not All Factors Are Equal: Courts in the Second Circuit apply a “strong presumption” that oversecured creditors get postpetition interest at the contract default rate. The familiar five-factor test examines: (1) estate solvency; (2) whether the rate is a penalty; (3) creditor misconduct; (4) harm to other creditors; and (5) impairment of the debtor’s fresh start.
Judge Bentley’s key clarification: solvency is a threshold, not just one of five factors. If the debtor is solvent, the presumption favoring the lender is nearly unrebuttable. If insolvent, the presumption is lighter, but still present—debtors must show one of the remaining factors warrants disallowance.
Applying the Factors: Debtor Comes Up Empty
– Penalty? The 16% rate was well within market norms, negotiated at arm’s length, and not usurious under New York law.
– Creditor Misconduct? None alleged or found.
– Harm to Creditors? Here, Judge Bentley made his most significant doctrinal contribution. He clarified that “harm to creditors” means more than just a dollar-for-dollar reduction in distributions. The harm must threaten the reorganization or distribution itself—not simply reduce insider recoveries.
– Fresh Start? Not applicable: the case was a liquidation, not a reorganization.
A Footnote for Insiders
Judge Bentley suggested that when only insiders benefit from disallowing default interest, the debtor may need to make an even stronger showing to rebut the presumption in the lender’s favor. This aligns with the logic that equity (or its affiliates) shouldn’t get a windfall by escaping a bargained-for default rate.
No Double Recovery: Default Interest or Late Charges, Not Both
Finally, Judge Bentley disallowed the lender’s claim for late charges, applying the well-settled rule: lenders may recover either default interest or late charges, but not both.
Takeaway
Insolvency alone will not defeat an oversecured creditor’s right to its contractual default interest under Bankruptcy Code section 506(b). Unless the debtor can show that the rate is a real penalty or misconduct or genuine harm to non-insider creditors, then these lenders will likely recover their default rates. Further, if only insiders stand to benefit from disallowance, the bar may be even higher.
