Conversion of Debentures
Conversion of debentures into equity shares — applicable to Optionally Convertible, Partially Convertible, and Fully Convertible Debentures — dilutes existing shareholders when conversion is exercised, with the conversion ratio, timing, and dilution mechanics governed by the debenture trust deed and SEBI regulations.
Convertible debentures are hybrid instruments that combine features of debt and equity, giving the holder the option or obligation to convert the outstanding debt into equity shares of the issuer at a predetermined conversion price or ratio. India's corporate financing landscape has long featured three variants: Optionally Convertible Debentures (OCDs), where the holder or the issuer has the option to trigger conversion; Partially Convertible Debentures (PCDs), where only a portion of the face value converts into equity and the remainder is redeemed in cash; and Fully Convertible Debentures (FCDs), where the entire face value converts into equity shares.
The mechanics of conversion rest on the conversion ratio specified in the debenture trust deed at the time of issuance. This ratio defines how many equity shares are issued per debenture upon conversion. If the conversion price is set at a premium to the then-prevailing market price, the debenture is out of the money at issuance; if the market price rises above the conversion price over time, the conversion option gains intrinsic value and holders are economically incentivised to convert.
For listed companies, SEBI regulations under the ICDR framework govern the pricing of convertible securities. The conversion price must comply with the pricing formula for preferential allotments — typically a minimum of the higher of the average market price over the preceding twenty-six weeks or two weeks, subject to conditions. This prevents listed companies from issuing convertible instruments at heavily discounted conversion prices that would allow selective dilution beneficial to connected parties.
Dilution impact is the central investor concern when conversion is approaching. If a company has issued convertible debentures representing, say, fifteen percent of the current fully diluted equity, conversion reduces the proportional ownership of existing shareholders by the same percentage. Earnings per share falls mechanically even if the company's absolute earnings are unchanged, because the denominator expands. Analysts computing diluted EPS under Ind AS 33 must include the potential dilutive effect of convertible instruments in their calculations, using the if-converted method.
The accounting treatment for convertible instruments under Ind AS 32 requires the issuer to bifurcate the instrument into a debt component (recognised at amortised cost based on the fair value of comparable non-convertible debt) and an equity component (representing the value of the conversion option), recorded directly in equity on initial recognition. This split accounting means the balance sheet and income statement treatment of convertible debentures differs significantly from vanilla bonds, affecting financial ratios such as interest coverage and return on equity.
