CoCos : Definition A CoCo bond is a loss-absorbing bond issued by a financial institution (bank or insurance company) that suffers either a conversion into equity or a write-down of its face value on the appearance of a trigger event. The loss absorbing mechanism is specified in the terms and conditions of the bond. 11! Lack! $ of standardization 50 bn issued in Europe! European banks mainly!

Host Instrument 20 The accouting trigger can be hit if Bank makes a loss which eats into the equity Regulator reviews the risk weighting of the assets Example: In June 2013, Denmark s FSA requested a review of Danske s IRB models, which results in a net increase of DKK100 billion (US$18 billion) or ~12.5% of group RWAs. In October 2013, the Ministry of Finance in Norway increased the LGD (loss given default) floors for residential mortgages. This has increased the riskweights 20
CoCos : Anatomy! Loss 21 Absorption Mechanism! Trigger Event The decision by the relevant authority to use public funds and inject these in the bank without which this bank would become non-viable.

Valuation : Credit Derivatives Approach! Credit 34 Triangle : cs = λ x (1- Πbond)! Link between a credit spread (cs), recovery rate (π) and instantaneous default probability (λ)! The parameter (λ) is also called default intensity.! The probability to go default during a particular time T is : 1- exp(-λt) 34
Valuation : Credit Derivatives Approach CoCo Spread 35 S* (Implied Trigger Level)? 35 64
Valuation : Credit Derivatives Approach! Hitting S* can be modeled.! In a Black-Scholes world, the probability p* of hitting S* is : 36 36
Valuation : Credit Derivatives Approach 37 Rule of Thumb Pricing for a Credit Default Swap: Credit Spread = Expected Loss * Default Intensity cs = (1 πbond) * λdefault The expected loss is determined by the value of the shares (S*) when conversion takes place. The CoCo investor loses the face value of the bond (N), but receives Cr shares instead. (The conversion ratio Cr = N / Cp ). Expected Loss = N - Cr x S* Rule of Thumb Pricing for a CoCo Spread: CoCo spread = (1- Stock price at trigger S*/Conversion price Cp) x λtrigger CoCo spread = (1 πcoco) * λtrigger λtrigger log(1 p* ) = T 37
Valuation : Credit Derivatives Approach 38 Calculate Recovery Bond Π=S*/Cp Choose S* Coco spread Calculate p* Calculate λ (probability of hitting this barrier) 38
