The Macabacus long-form LBO model is derived from actual LBO models used by four bulge bracket investment banks, incorporating the best practices and features of each. We believe it sets a new standard for balancing complexity and intuitive use among LBO models. Our model implements key concepts related to LBO modeling, including revolving credit facilities, senior debt, subordinated debt, and preferred stock financing; fixed and floating interest rates; cash sweep; original issue discount (OID); payment-in-kind (PIK) instruments; and much more. You will find annotations throughout the model to facilitate your understanding of its structure and assumptions.
