BaaS loan expense represents the amount paid or payable to partners for credit enhancement and servicing CCBX loans. To determine net revenue (Net BaaS loan income) earned from CCBX loan relationships, the Company takes BaaS loan interest income and deducts BaaS loan expense to arrive at Net BaaS loan income which can be compared to interest income on the Company’s community bank loans. (2) CCBX - net BaaS loan income represents BaaS loan interest income minus BaaS loan expense divided by average CCBX loans. This produces a ratio which can be compared to average yield of community bank loans. Refer to the "Non-GAAP Reconciliation" in the Appendix for more information. (3) Net interest margin, net of BaaS loan expense represents CCBX net interest income less BaaS loan expense divided by average earning assets. This produces a ratio that can be compared to net interest margin of the community bank. Refer to the "Non-GAAP Reconciliation" in the Appendix for more information.
