Key Terms

Participating vs. Non-Participating Preferred

Participating Preferred Participating preferred holders receive their full liquidation preference first, the original investment amount, sometimes plus accumulated dividends, and then immediately participate with common stockholders pro rata in all remaining value. This is sometimes called a double-dip because preferred holders benefit twice: once from the liquidation preference and again from the pro rata upside.

Non-Participating Preferred (Convertible Preferred)

Convertible preferred holders also receive their liquidation preference first, but they only participate in value above that threshold. At the point where the per share value of common reaches the conversion price, the preferred converts to common and all classes share pro rata in the remaining proceeds. Below that threshold, convertible preferred holders simply take their preference, and common receives the rest.

Why It Matters Whether preferred is participating or convertible is one of the most negotiated terms in any deal. Participating preferred is more favorable to investors in moderate exit scenarios. Convertible preferred is more founder-friendly and more common in VC-backed deals.

Dividends and Interest

Cumulative Dividends. Some preferred equity carries a cumulative dividend, meaning the dividend accrues over time, whether or not it is paid in cash. When a liquidity event occurs, the accumulated dividends are added to the liquidation preference before proceeds flow to other classes. This increases the amount preferred holders receive before common stock participants.

Non-Cumulative Dividends Non-cumulative dividends do not accrue. If they are not declared and paid in a given period, they are simply forfeited. Most VC-backed preferred equity is non-cumulative.

PIK Interest (Payment in Kind) PIK interest is a form of accruing interest on convertible debt where the interest is not paid in cash but instead added to the outstanding principal balance. At conversion or repayment, the full accrued balance, principal plus PIK interest, is due. PIK mechanics increase the total amount a debt holder receives relative to a simple interest structure.

Cash Interest Standard cash interest on convertible debt is paid periodically at a fixed rate. Unlike PIK interest, it does not compound into the principal balance.

IRRs, 2x and Beyond

Internal Rate of Return (IRR) IRR is the annualized rate of return on an investment, accounting for the timing of cash flows. In PE and VC, IRR is one of the two primary measures of fund performance alongside MOIC. A higher IRR reflects faster and larger returns relative to the capital invested. IRR is time-sensitive; the same cash return achieved in two years generates a much higher IRR than the same return achieved in five years.

MOIC (Multiple on Invested Capital) MOIC measures the total return on an investment as a simple multiple of the capital invested, regardless of how long it took. A 2x MOIC means the investor received twice their invested capital back. A 3x MOIC means three times. MOIC is a gross measure and does not account for the time value of money the way IRR does. Both metrics are used together to give a complete picture of investment performance.

Return Hurdles Many preferred equity structures and fund waterfall agreements include return hurdles, minimum IRR or MOIC thresholds that must be met before carried interest or additional participation kicks in. Common hurdles include an 8% preferred return or a 1.5x to 2x MOIC before the general partner begins receiving carry.

2x and Beyond In PE and VC, a 2x return on invested capital is often considered the baseline for a successful deal. Returns of 3x or more indicate strong performance. The tranche discount rates used in the DFPM reflect these return expectations, with senior debt requiring approximately 12% and common equity requiring 23.5% or more to compensate for the higher risk and subordinate position in the waterfall.

Convertible Debt

Convertible debt is a promissory note that converts into equity at a future financing event or liquidity event. It is commonly used as bridge financing or in pre-priced rounds. Key terms include a conversion price discount to the next round, typically 10 to 30 percent, and a valuation cap that limits the upside on conversion. In a sale or liquidation, the holder typically has the right to either receive repayment of principal plus interest or convert and participate in the sale proceeds. Convertible debt is senior to equity in a liquidation and may be pari passu with or senior to other notes, depending on the intercreditor agreement.

SAFE (Simple Agreement for Future Equity)

Created by Y Combinator in 2013 as a founder-friendly alternative to convertible debt, a SAFE is not debt; it carries no maturity date and no interest. It is a contractual right to receive equity in a future financing round. Conversion mechanics are similar to convertible debt, a discount of 10 to 30 percent and a valuation cap, but without the creditor protections of a note. In a liquidation, the principal is typically repaid if funds are available, sometimes with a premium return of 1.5x. SAFEs are typically pari passu with other SAFEs.

Liquidation Priority Where Each Term Fits in the Waterfall

Understanding how these terms connect to waterfall priority is the key to applying them in practice. Convertible debt sits senior to all equity in a liquidation. SAFEs sit senior to equity but are typically unsecured. Preferred equity, whether participating or convertible, holds priority over common in Tranche 2. Dividends and accumulated interest increase the amount due in that tranche. IRR hurdles and MOIC thresholds determine when carried interest and additional participation kick in above the base preference. Common equity and options receive whatever remains after all prior claims are satisfied.
