Capital Structure of an LBO

In a leveraged buyout (LBO), the target company's existing debt is usually refinanced (although it can be rolled over) and replaced with new debt to finance the transaction. Multiple tranches of debt are commonly used to finance LBOs, and may including any of the following tranches of capital listed in descending order of seniority:

Revolving Credit Facility ("Revolver")

A revolver is a form of senior bank debt that acts like a credit card for companies and is generally used to help fund a company's working capital needs. A company will "draw down" the revolver up to the credit limit when it needs cash, and repays the revolver when excess cash is available (there is no repayment penalty). The revolver offers companies flexibility with respect to their capital needs, allowing companies access to cash without having to seek additional debt or equity financing.

There are two costs associated with revolving lines of credit: the interest rate charged on the revolver's drawn balance, and an undrawn commitment fee. The interest rate charged on the revolver balance is usually LIBOR plus a premium that depends on the credit characteristics of the borrowing company. The undrawn commitment fee compensates the bank for committing to lend up to the revolver's limit, and is usually calculated as a fixed rate multiplied by the difference between the revolver's limit and any drawn amount.

Bank Debt

Bank debt is a lower cost-of-capital (lower interest rates) security than subordinated debt, but it has more onerous covenants and limitations. Bank debt typically requires full amortization (payback) over a 5- to 8-year period. Covenants generally restrict a company's flexibility to make further acquisitions, raise additional debt, and make payments (e.g. dividends) to equity holders. Bank debt also has financial maintenance covenants, which are quarterly performance tests, and is generally secured by the assets of the borrower. Existing bank debt of a target must typically be refinanced with new bank debt due to change-of-control covenants.

Bank debt, other than revolving credit facilities, generally takes two forms:

Term Loan A – This layer of debt is typically amortized evenly over 5 to 7 years.

Term Loan B – This layer of debt usually involves nominal amortization (repayment) over 5 to 8 years, with a large bullet payment in the last year. Term Loan B allows borrowers to defer repayment of a large portion of the loan, but is more costly to borrowers than Term Loan A.

The interest rate charged on bank debt is often a floating rate equal to LIBOR plus (or minus) some premium (or discount), depending on the credit characteristics of the borrower. Depending on the credit terms, bank debt may or may not be repaid early without penalty.

High-Yield Debt ("Subordinated Notes", "Junk Bonds")

High-yield debt is typically unsecured. High-yield debt is so named because of its characteristic high interest rate (or large discount to par) that compensates investors for their risk in holding such debt. This layer of debt is often necessary to increase leverage levels beyond that which banks and other senior investors are willing to provide, and will likely be refinanced when the borrower can raise new debt more cheaply. Subordinated debt may be raised in the public bond market or the private institutional market, carries a bullet repayment with no amortization, and usually has a maturity of 8 to 10 years.

A company retains greater financial and operating flexibility with high-yield debt through incurrence, as opposed to maintenance, covenants and a bullet (all-at-once) repayment of the debt at maturity. Additionally, early payment options typically exist (usually after about 4 and 5 years for 7- and 10-year high-yield securities, respectively), but require repayment at a premium to face value. Interest rates for these securities are higher than they are for bank debt.

The interest on high-yield debt may be either cash-pay, payment-in-kind ("PIK"), or a combination of both. Cash-pay means that coupon is paid in cash, like the interest on bank debt. PIK means that the issuer can pay interest in the form of additional high-yield debt, so as to increase the face value of the debt that must ultimately be repaid. Sometimes, high-yield debt is structured so that the issuer may choose between cash-pay and PIK (the PIK option is usually more attractive to the issuer). Also, the mezzanine debt may be structured so that the PIK option is available for the first few years of the debt's life, after which cash-pay becomes mandatory.

Mezzanine Debt

The mezzanine ranks last in the hierarchy of a company's outstanding debt, and is often financed by private equity investors and hedge funds. Mezzanine debt often takes the form of high-yield debt coupled with warrants (options to purchase stock at a predetermined price), known as an "equity kicker", to boost investor returns to acceptable levels commensurate with risk. For example, regular subordinated debt might have an interest rate of 10%, while a hedge fund investor expects a return (IRR) in the range of 18-25%. To bridge this gap and attract investment by the hedge fund investor, the borrower could attach warrants to the subordinated debt issue. The warrants increase the investor's returns beyond what it can achieve with interest payments alone through appreciation in the equity value of the borrower.

The debt component has characteristics similar to those of other junior debt instruments, such as bullet payments, PIK, and early repayment options, but is structurally subordinate in priority of payment and claim on collateral to other forms of debt. Like subordinated notes, mezzanine debt may be required to attain leverage levels not possible with senior debt and equity alone.

Seller Notes

A portion of the purchase price in an LBO may be financed by a seller's note. In this case, the buyer issues a promissory note to the seller that it agrees to repay (amortize) over fixed period of time. The seller's note is attractive to the financial buyer because it is generally cheaper than other forms of junior debt and easier to negotiate terms with the seller than a bank or other investors. Also, the acceptance of a seller's note by the seller signals the seller's faith and confidence in the business being sold. However, seller financing may be unattractive to the seller because the seller retains the risks associated with the business without having any control over it. Moreover, the seller's receipt of proceeds from the sale is delayed.


Securitization of the cash flows attributable to particular assets, such as receivables or inventory, may provide another source of financing when a secondary market for securitization of such assets exists.

Common Equity

Equity capital is contributed through a [private equity] fund that pools capital raised from various sources. These sources might include pensions, endowments, insurance companies, and wealthy individuals.

Exhibit A – Tranches in the LBO Structure

Source of Funds   Key Terms   Comments
Bank Debt  
  • Typically 30-50% of capital structure
  • Based on asset value as well as cash flow
  • LIBOR-based (i.e. floating rate) term loan

  • 2.0x - 3.0x LTM EBITDA (varies with industry, ratings, and economic conditions)
  • Secured by all assets and pledge of stock
  • Maintenance and incurrence covenants

Total Debt  
  • Typically 3.0x - 6.0x LTM EBITDA
  • Interest coverage at least 2.0x LTM EBITDA/first year interest
  • Total debt varies by sector, market conditions, and other factors
Common Equity  
  • Typically 20-35% of capital structure
  • 20-30% IRR on about a 5-year holding period
  • Exit multiple = entry multiple
  • Management options of 5-10%
  • Required IRR may be lower for larger or less risky transactions

Early Repayment Penalties

When a borrower repays its loans early, the lender must reinvest the repayments to earn acceptable returns. However, there is some risk that the lender will be unable to loan money on terms equivalent or better than it obtained from the borrower who is repaying early if, for example, interests rates may have declined since the lender originally made the loan to the borrower. To mitigate this risk, lenders sometimes charge borrows a premium to repay their loans early.

Credit Statistics

When considering an appropriate capital structure for an LBO transaction, is it very important to target realistic credit statistics. Credit statistics that are calculated as a multiple of interest expense are called "financial coverage" ratios.

Exhibit B – Typical Credit Statistics

Parameter   Typical Value*
Total Debt / EBITDA   4.5x - 5.5x
Senior Bank Debt / EBITDA   3.0x
EBITDA / Interest Coverage   > 2.0x
(EBITDA − CapEx) / Interest Coverage   > 1.6x

* These parameters will change with market conditions. Consult the leveraged finance group at an investment bank for current parameters. Also, the financing limit will depend on the circumstances specific to the transaction and the growth potential of the target.
