Chinese convertibles: Equities in fancy dress?

Chinese convertibles: Equities in fancy dress?

  • The market for bonds that convert to China A shares has grown considerably in the last two years.
  • Some characteristics of A-share convertible bonds may lead investors to consider them essentially as equities.
  • But our analysis illustrates the importance of these bonds’ non-equity-like characteristics, which dedicated modeling could help investors understand.

The Chinese convertible-bond market has grown considerably over the last two years — especially those bonds that convert to A shares, as shown in the exhibit below.1 These securities offer investors income in the form of coupon payments, while still allowing for the potential to convert to A shares. At first glance, these convertibles look so similar to equity issues that one might see them as equity investments in disguise. Nevertheless, according to our research, investors who consider these convertibles to be pure equity may be missing an important part of the investment picture.

Common characteristics of China convertibles

Even at their time of issue, many of these securities act more like equities than bonds, because of specific features particularly prevalent in China2:

  • Low conversion price (strike price): A low strike price means conversion probability can be relatively high even at the time of the convertibles’ issue.
  • Dilution protection: If additional equity is issued at a price lower than the current price, the conversion price may be lowered, mitigating the adverse effect of dilution.
  • Dividend protection: Investors may be compensated for missing the dividend payments the underlying stock provides (to which they are otherwise not entitled until conversion) by the lowering of the conversion price. (This has become the norm for non-Chinese markets too.)

Other terms prevalent in China make it easier for issuers to trigger conversion or compensate investors if conversion was not viable during the lifetime of the bond:

  • Compensation if no conversion: Some convertibles may redeem above par (110% of notional amount, for example), which may partially mitigate the downside risk that the underlying equity underperforms and the bond is not converted.
  • Annual reset: In order to mitigate the effect of declining equity markets, issuers may periodically lower the conversion price, so that conversion becomes more beneficial to bondholders.

Equity-like is not the same as equity

Does this reset feature make these bonds behave essentially like equities? Not really. According to our analysis using MSCI’s convertible-bond model, there are more to A-share convertibles than just their equity-like characteristics.

We analyzed a hypothetical portfolio consisting of all bonds that convert to A shares.3 We then used performance attribution to analyze return drivers since October of last year. We looked at traditional factors, such as equity and spread, plus an additional convertible-specific factor, which accounts for peculiarities of the Chinese market.

A-share convertibles’ non-equity-like features are complex

One can immediately see that, beyond the equity factor, the spread and convertible-specific factor were important contributors to these convertible securities’ total returns during the period of our analysis. These last two contributors may reflect particular features of these convertibles, specifically the annual resets that serve to increase the value of convertibles as the underlying equities are declining. The spread and convertible-bond-specific factors may have also been driven by increased demand from yield-hungry fixed income investors.

If A-share convertibles’ issuance remains strong, these securities may become a bigger part of global bond portfolios. Because of these securities’ China-specific features, they warrant dedicated analysis. Investors can use models that account for these features to derive insight into this market and support their portfolio decisions.

1China A shares are offered by companies in mainland China that trade on the Shanghai Stock Exchange and Shenzhen Stock Exchange.

2There is nothing stopping European or U.S. companies from issuing convertible bonds with these features, but these features are more prevalent in China than in other markets.

3The universe of bonds was restricted to those bonds with a minimum quality threshold for price data.
