(1) | The overcollateralization ratio divides the total principal balance of all collateral in the CLO by the total principal balance of the bonds associated with the applicable ratio. To the extent an asset is considered a defaulted security, the asset’s principal balance for purposes of the overcollateralization test is the lesser of the asset’s market value or the principal balance of the defaulted asset multiplied by the asset’s recovery rate which is determined by the rating agencies. Rating downgrades of CLO collateral will generally not have a direct impact on the principal balance of a CLO asset for purposes of calculating the CLO overcollateralization test unless the rating downgrade is below a significantly low threshold (e.g., CCC-) as defined in each CLO vehicle.
(2) | The interest coverage ratio divides interest income by interest expense for the classes senior to those retained by us.
