Anti-Dilution Provisions in Indian Startups: Full Ratchet vs Broad-Based Weighted Average

Anti-dilution provisions are a standard feature of CCPS terms in Indian institutional funding rounds. They protect investors when a company raises a future round at a lower price per share than the investor originally paid. When triggered, they adjust the conversion ratio of the investor's CCPS, giving the investor more equity shares at conversion than originally agreed.

This post explains how anti-dilution provisions work, the two main mechanisms used in Indian VC, how each one affects the cap table in a down round, and the India-specific regulatory constraints that apply to foreign-held CCPS.

What Is Anti-Dilution Protection?

Anti-dilution protection is a provision in CCPS terms that adjusts an investor's conversion ratio when a down round occurs. A down round is any funding round in which new shares are issued at a price per share lower than the price paid by an existing investor.

Without anti-dilution protection, a down round dilutes all existing shareholders proportionally. The investor who paid ₹1,000 per share holds the same number of CCPS, but those CCPS now represent a smaller percentage of the company because new shares have been issued at a lower price. The investor absorbs this dilution exactly as founders and ESOP holders do.

With anti-dilution protection, the investor's conversion ratio is adjusted downward. Instead of converting at the original 1:1 ratio, they convert at a higher ratio, receiving more equity shares per CCPS. Their post-conversion ownership percentage is higher than it would have been without the adjustment. That additional ownership comes from a redistribution of shares across the existing cap table, primarily from founders and holders without anti-dilution protection.

Anti-dilution provisions only trigger in down rounds. If a company raises at a higher price per share than the existing investor paid, no adjustment occurs. The investor benefits from the valuation increase like everyone else.

The Two Mechanisms: Full Ratchet and Weighted Average

Full Ratchet Anti-Dilution

Full ratchet is the simplest anti-dilution mechanism and the most investor-protective. Under full ratchet, if any new shares are issued at a price lower than what the investor paid, the investor's entire conversion price resets to the new lower price, regardless of how many shares are issued at that price.

The formula is:

New Conversion Price = New Issue Price Per Share

This means the investor is treated as if they had originally invested at the down-round price. They receive significantly more equity shares at conversion to compensate for the price reduction.

Worked example:

A Series A investor puts in ₹10 crores at ₹1,000 per share, receiving 10,000 CCPS. Conversion ratio: 1:1, converting to 10,000 equity shares.

The company raises a Series B at ₹500 per share (a 50% down round).

Under full ratchet, the Series A conversion price resets from ₹1,000 to ₹500. The investor's ₹10 crore investment now converts at ₹500 per share, producing 20,000 equity shares instead of 10,000.

The investor's share count doubles. That doubling happens at the direct expense of everyone else on the cap table. If the founder held 60% before the adjustment, their effective percentage is now meaningfully lower because the total share count has increased significantly.

A 40% down round under full ratchet can reduce founder ownership by 10 to 20 percentage points. The same down round under broad-based weighted average typically reduces founder ownership by 1 to 2 percentage points. The difference is substantial.

Full ratchet is rare in institutional Indian VC deals from Series A onwards. It appears more commonly with some early-stage angel investors. Most practitioners consider full ratchet to be an aggressive provision that creates significant misalignment.

Broad-Based Weighted Average Anti-Dilution

Broad-based weighted average is the market standard for anti-dilution protection in Indian institutional VC. It adjusts the conversion price to a weighted average between the original price and the new lower price, proportional to how many shares are issued at the lower price relative to the total share count.

The formula:

New Conversion Price = Old Conversion Price × (Shares Outstanding Before Round + Hypothetical Shares at Old Price) / (Shares Outstanding Before Round + Actual Shares Issued at New Price)

"Hypothetical shares at old price" represents how many shares the new investment would have bought at the original higher price. Because the actual price is lower, more shares are issued, and this difference drives the downward adjustment in the conversion price.

Same example under broad-based weighted average:

Series A: 10,000 CCPS at ₹1,000. Total shares outstanding before Series B: 90,000. Series B: ₹5 crores raised at ₹500 per share, issuing 10,000 new shares. Hypothetical shares at ₹1,000: ₹5 crores / ₹1,000 = 5,000 shares.

New Conversion Price = ₹1,000 × (90,000 + 5,000) / (90,000 + 10,000) = ₹1,000 × 95,000 / 100,000 = ₹950.

The Series A investor converts at ₹950 per CCPS instead of ₹1,000. Their 10,000 CCPS convert to approximately 10,526 equity shares instead of 10,000. They receive 526 additional shares: a proportional adjustment rather than a full reset.

The founder dilution from this adjustment is marginal, not catastrophic.

Broad-Based vs Narrow-Based Weighted Average

Within weighted average anti-dilution, the distinction between broad-based and narrow-based determines what counts as "shares outstanding" in the formula.

Broad-based includes all fully diluted shares: common shares, all CCPS on an as-converted basis, the entire ESOP pool including ungranted options, and all warrants and convertible instruments. This produces a larger denominator, a higher adjusted conversion price, and less dilution for founders. It is the more founder-friendly variant and is the institutional standard.

Narrow-based counts only issued and outstanding shares, excluding ungranted options and warrants. The smaller denominator produces a lower adjusted conversion price, more shares for the investor, and more dilution for founders. It favours investors more than broad-based.

Indian founders should always push for broad-based weighted average. The difference between broad-based and narrow-based can be meaningful in companies with large ESOP pools, where the exclusion of ungranted options from the denominator increases the anti-dilution adjustment.

Comparison: How Each Mechanism Performs in a Down Round

The FEMA Constraint for Foreign Investors

Anti-dilution provisions for foreign-held CCPS face a regulatory constraint that does not apply to domestic investors. Under the Foreign Exchange Management (Non-Debt Instruments) Rules, 2019, the price at which CCPS held by foreign investors converts into equity shares cannot fall below the fair market value of the equity shares at the time the CCPS was originally issued.

This creates a floor on how far the anti-dilution adjustment can go. A broad-based weighted average calculation that produces a conversion price below the original FMV of the equity may not be enforceable under FEMA for foreign holders.

In practice, this means that anti-dilution adjustments for foreign-held CCPS work as agreed in moderate down rounds but may face enforcement constraints in severe down rounds where the adjusted conversion price approaches or falls below the original FMV. Any startup with foreign institutional investors should ensure anti-dilution mechanics are drafted with explicit FEMA compliance in mind.

There is also a tax dimension. Under Section 56(2)(x)(c) of the Income Tax Act, 1961, shares issued at below fair market value may be treated as income in the hands of the recipient. Depending on how the anti-dilution adjustment is implemented, including whether it is achieved through a conversion ratio adjustment or a share issuance, this provision may create tax liability at the adjustment point.

How Anti-Dilution Interacts With the Exit Waterfall

Anti-dilution adjustments change the conversion ratio, which changes the investor's ownership percentage on an as-converted basis. This directly affects exit waterfall calculations in two ways.

First, the investor's post-conversion equity stake is higher after an anti-dilution adjustment. At exits where the investor converts to common equity rather than taking the preference waterfall, their share of the exit proceeds is proportionally higher.

Second, the conversion threshold changes. The exit size at which it becomes rational for the investor to convert to common equity rather than take the preference is: preference amount / as-converted ownership percentage. If anti-dilution has increased the ownership percentage, the conversion threshold falls: the investor converts at lower exit values than before the adjustment.

For founders modelling exit scenarios after a down round, the anti-dilution adjustment must be calculated first and the resulting as-converted ownership percentages applied in the waterfall. Running the waterfall on pre-adjustment percentages produces an inaccurate picture.

Pay-to-Play Provisions

Some SHA terms include a pay-to-play provision that requires investors to participate in future funding rounds to maintain their anti-dilution rights. Investors who do not participate may have their CCPS converted to common equity, losing preference rights and anti-dilution protection.

Pay-to-play provisions serve as an incentive for existing investors to support the company through difficult rounds. They prevent a situation where investors free-ride on the preference stack without contributing new capital when the company needs it. For founders, pay-to-play can be a useful term to negotiate into a SHA from the outset, particularly in environments where down rounds are possible.

Frequently Asked Questions

Can anti-dilution protection be removed from a term sheet entirely? Rarely. Most institutional investors require some form of anti-dilution protection as a standard condition. The negotiation is about which mechanism, not whether it exists. The exception is the earliest pre-seed or angel rounds where terms are less formalised.

What is a down round and how often do Indian startups experience them? A down round is any funding round in which new shares are issued at a lower price per share than the previous round. Down rounds become more common during periods of market correction, reduced VC activity, or when a company's growth has fallen short of projections. Anti-dilution provisions are specifically designed for this scenario.

Does anti-dilution affect ESOP holders? Yes, indirectly. An anti-dilution adjustment that increases an investor's share count dilutes all other existing shareholders proportionally, including ESOP holders. In a broad-based weighted average structure, the ESOP pool is included in the denominator of the formula, which reduces the adjustment and partially cushions this dilution. In a full ratchet or narrow-based structure, ESOP holders absorb more of the adjustment.

What happens if anti-dilution protection conflicts between different CCPS series? In a multi-round company, each CCPS series may have different anti-dilution terms. A down round can trigger adjustments under multiple SHAs simultaneously. If the adjustments produce conflicting outcomes, or if one series has seniority that affects how the adjustments are implemented, the interaction can be complex. This is one reason to ensure that anti-dilution terms are consistent across rounds and reviewed holistically at each new fundraise.

Conclusion

Anti-dilution provisions are a standard feature of institutional CCPS terms. Their purpose is legitimate: to protect investors against the risk that they overpay relative to a subsequent round.

The mechanism matters. Full ratchet resets the conversion price entirely and can dramatically increase an investor's ownership in any down round, regardless of severity. Broad-based weighted average adjusts the price proportionally, producing a small adjustment for small down rounds and a larger but bounded adjustment for larger ones. For founders, the difference between the two mechanisms in a significant down round can be 10 to 20 percentage points of ownership.

Broad-based weighted average is the market standard among Indian institutional investors and is the appropriate benchmark for any anti-dilution negotiation.
