Why has the share dropped., page-82

So CGF's capital structure and hence value would be very susceptible to a bond "crash" or sell-off.

It depends.

If it is just a broad-based bond sell-off we're talking about (i.e. a generic widening in credit spreads, and/or a rise in benchmark yields), CGF will be largely neutral, because the bulk of their annuity liabilities will also be revalued at a higher base yield and Illiquidity Premium (which is a function of credit spreads). That is exactly what happened in 2016H1 (see my previous post).

On the other hand, if the bond crash is driven by a large amount of actual defaults (failure to pay, restructuring, etc.) in the bond portfolio, or by a material widening of credit spreads specific to a particular sector (e.g. RMBS/CMBS), then CGF would indeed take a big hit in terms of PCA ratio, in all likelihood.

Let me know if there is anything unclear.
