PIK Interest

How to Model the PIK Toggle

In practice, debt securities, namely corporate bonds, often come with a fixed PIK schedule outlined in the lending agreement.

But another form of PIK interest is referred to as a PIK toggle, which is an agreement between the issuer and borrower that provides the borrower with the option to defer an interest payment if needed.

Based on the liquidity needs of the borrower (i.e. cash on hand) or other conditional provisions, this feature lets a borrower reduce its cash outflows.

If a PIK toggle is in place, the decision on whether interest expense is paid-in-cash or PIK becomes more of a discretionary decision made on the specific circumstances regarding the credit health of the borrower.

PIK interest can be especially attractive to borrowers looking to avoid interest payments to conserve cash (i.e., leveraged buyouts).

In addition, companies that have found themselves in poor financial conditions and in need of debt restructuring can seek to renegotiate debt terms to include the option for PIK.

Is PIK Interest Tax Deductible?

To confirm your understanding of the PIK interest concept, review the following accounting question.

Q. If a company has incurred $10 in PIK interest, how are the three financial statements impacted?

• Income Statement (I/S) → Interest expense will increase by $10 on the income statement, which causes net income to decrease by $7 given a 30% tax rate assumption.
• Cash Flow Statement (CFS) → On the cash flow statement, net income will be down by $7, but the $10 non-cash PIK interest is added back. The ending cash balance will reflect an increase of $3.
• Balance Sheet (B/S) → On the assets side of the balance sheet, cash will have increased by $3. Then on the liabilities & equity side, the debt balance should have increased by $10 since the PIK accrues to the debt’s ending balance, and net income is going to be down by $7. Putting them together, both the assets and liabilities & equity side is up by $3 (and the balance sheet remains in balance).

How to Adjust Coverage Ratio for PIK Interest

Note that lending agreements occasionally include interest expense to be paid in the form of “paid-in-kind” interest (or PIK interest), rather than cash interest.

In such cases, an interest expense coverage ratios can be adjusted to exclude the effects of any PIK interest.

In effect, only the cash portion of interest expense should be included in the calculation, because PIK is not an actual outflow of cash.

All else being equal, PIK interest increases interest coverage ratios since they are not counted as part of the “interest” line, but note that interest is still accruing to the debt principal and is due at maturity.

1. Subordinated Notes Assumptions

Suppose we’re tasked with forecasting the interest expense of a hypothetical company that has borrowed subordinated notes with the PIK optionality.

The debt assumptions we’ll use for this modeling exercise are listed below.

• Subordinates Notes, Beginning Balance (Year 1) = $1m
• PIK Interest Rate = 8.0%
• Cash Interest Rate = 4.0%

Rather than a straight 12.0% cash interest rate, 4.0% will be paid-in-cash with 8.0% charged in the form of PIK – meaning that throughout the borrowing period, the 8.0% PIK interest accrues towards the beginning balance.

2. PIK Interest Calculation Example

In Year 1, the beginning balance of $1m is multiplied by the 8.0% PIK rate to calculate the interest expense, which comes out to be $80k.

Therefore, we can see how the $80k of interest accrued towards the principal for the ending balance calculation for Year 1 for a total of $1.08m.

Here, we can see the direct impact that accrued interest (and the increased balance) has on the amount of interest due each period; or put differently, the compounding effects of PIK interest.

For comparison, we’ll calculate the portion of interest expense paid in cash by multiplying the interest rate (4.0%) by the average subordinated notes balance.

And since using the average balance in the interest expense formula introduces a circularity into our model, we’ll add a circuit breaker.

• OFF → If the circularity cell ($K$4) is set to 1, the circuit breaker is turned off
• ON → Or if a zero is entered into the cell, the circuit breaker is switched on, and the output will be zero (i.e. cutting off the circularity-inducing calculation)

For instance, the Year 1 cash interest expense is equal to the 4.0% cash interest rate multiplied by the average of the beginning and ending Year 1 sub-notes balance ($1m and $1.08m). This comes out to $42k for the cash interest payment in Year 1.

If the cash interest component did not exist and the form of interest was instead PIK, no cash interest would be paid throughout the term of the loan.

3. PIK Interest Analysis Example

Once the debt matures, the borrower must repay the original debt principal and all the accrued interest.

But in our simplified example, the subordinated notes balance at the end of each period is equal to the sum of the PIK beginning balance and PIK interest accrued.

So in closing, the principal of the subordinated notes has reached approximately $1.47m by the end of Year 5 from the initial balance of $1m at the beginning of Year 1.
