Intercreditor agreements between multiple lenders are part and parcel of lending to a company with several tranches of debt. Under section 510 of the United States Bankruptcy Code (the “Code”), “[a] subordination agreement is enforceable in a case under this title to the same extent that such agreement is enforceable under applicable nonbankruptcy law.” 11 U.S.C. § 510(a) (West 2017).
