3 Introduction

A Contingent Convertible (CoCo) bond is a debt instrument that converts into equity or writes down as soon as the banks gets into a life threatening situation. Conversion/write down happens via a predefined trigger mechanism: e.g. Common Equity Tier-1 (CET1) falling below 7% and is often accompanied with a regulatory trigger. For CoCos with a conversion feature, this creates dilution for existing shareholders, but protects potentially taxpayers.

4 What is a CoCo ?

In the aftermath of the financial crisis Contingent Capital solutions were proposed to strengthen bank’s Additional Tier 1 (AT1) and Tier 2 (T2) capital levels.

CoCos are such AT1 or T2 instruments and are situated in the hybrids area of the balance sheet in between equity and traditional debt.

Under the new EU Capital Requirements Directive (CRD4), all new AT1 capital needs to have CoCo features.

5 What is a CoCo ?

n CoCos are issued as bonds, but the more the bank is in trouble, the more CoCos start behaving as equity.

n How to model it: as fixed income or as equity ?

n How to threat it : as a child or and adult ?

“Like teenagers, they spend many hours in their bedrooms, suspiciously quiet, you never knowing what they are up to, and then suddenly there’s an outburst of sound and fury, the cause of which you never understand. Hybrid instruments and teenagers are both to be treated with love and understanding.”

Paul Wilmott

environment rather small.

•  Liquidity component: CoCos are new asset class with only relative liquidity and a still a lot of regulatory uncertainty and model uncertainty.

•  Extension risk component: Most CocCs are callable bonds . However most of the time no step-up is present/allowed.

•  Coupon cancellation risk: For some CoCos (T1) coupons are cancellable at the discretion of the issuer/regulator. They are typically non cumulative.

•  Conversion component: compensates for the event that the CoCo bond is converted into equities or reduced in value.

•  Optional Conversion component: reduces because of the right of the investor to participate in the positive performance of the underlying shares (CoCoCo only).

13 CoCo  Yield  Breakdown   On average, CoCos offer a 4 times spread pickup over senior, or over 400 basis points in absolute terms.

14 Who  buys  CoCos  ?  

14

n Asset Managers: Have the expertise and have previously been exposed to hybrid instruments (pre-2008). Have large existing holdings in T1-T2 products. There have been some recent launches of CoCo funds.

n Hedge Funds Have more risk-appetite and have the experience to hedge to some extend the unwanted risks away.

n  Insurance Industry Solvency II favors short dated, high rated debt. This is opposite to what CoCos stand for. However the extra yield is often attractive.

n Employees Some investment banks (Barcap, CS) pay CoCo bonuses to their top-management.

“…A finishing school (or charm school) is a private school for girls that emphasizes training in cultural and social activities. The name reflects that it follows on from ordinary school and is intended to complete the educational experience, with and emphasis on etiquette….” CoCos are the finishing touch in the strengthening of the capital of the Swiss banks.

24 CoCos and the ECB’s comprehensive assessment (2014)

CoCos can be used to offset the capital shortfall. The caveat is here the fact that the AT1 CoCo bonds have their trigger set at 5.125%. They therefore cannot be put at work in the stress tests.

30 Quantitative Aspects of CoCos

31 All CoCos are different CoCos Anatomy •  Maturity (> 5y)

•  Coupon (7-10 % ?)

•  Trigger Event

§  Accounting: e.g. CET1 <7% §  Regulatory Trigger §  Market Trigger (not implemented)

•  Loss Absorbing Mechanism §  Conversion

•  Conversion Price = Issue Price (Lloyds) CP = S0

•  Conversion Price = fraction of Issue Price (BarCap) CP = α S0

•  Conversion Price = Trigger Price CP = S*

•  Floored Conversion Price (CS, BBVA, …) CP = max (Floor, S*)

•  Write-Down •  Partially (Rabo (75%)) •  Full (Barclays, KBC, CS,… ) •  Staggered (ZKB,…)

Conversion/Write-Down Mechanism determines the Recovery Rate of the CoCo

SENIOR (40% Recovery)COCO (25% RECOVERY)

Example 1: The Rabobank cds spread (senior) is 65bp. For an expected recovery rate of 40%, this corresponds to an estimate of λdefault of 1.09% = 0.65%/(1-0.4).

Rule of Thumb Pricing for a CDS: Credit Spread = Expected Loss x Default Intensity

cs = (1 – RCDS) x λdefault

Example : When will the Rabobank CoCo trigger: λtrigger = ? On the trigger event, there is a haircut of 75%. The recovery is hence 25% (RCoCo = 25%). Suppose, the CoCo spread of the Rabobank CoCo is 304 bp. λtrigger = 3.04% / (1-0.25)= 4.05%. Note that conversion happens before default : λtrigger > λdefault

Rule of Thumb Pricing for a CoCo Spread: CoCo spread = (1 – RCoCo) x λtrigger

ASSUME: Triggering happens when the stock prices hits a certain barrier. We replace the “CET1 falling below X%”event by “Stocks hits the a low barrier H”.

•  For Equity Conversion CoCos, the expected loss is determined by the value of the shares (S*) when conversion takes place : The CoCo investor pays Cp for each share with value S*: Recovery Rate (%) = RCoCo = S* / Cp

CoCo  Pricing  (APPENDIX)  

Rule of Thumb Pricing : CoCo spread = (1 – S* / Cp) x λtrigger Equity Model: Smile Adjusted Black-Scholes

52

•  We break down a CoCo bond into different derivative instruments:

A. Face Value + Coupons: BOND (long)

B. Conversion into stock: DOWN-AND-IN-FORWARD (long) Write-down: BINARY DOWN-AND-IN-BARRIER (short)

C. Cancellation of Coupons BINARY DOWN-AND-IN BARRIERS (short)

CoCo  Pricing  :  Equity  Deriva?ves  Approach  (APPENDIX)  

CoCo Price = A (Bond Part) + B (Loss Absorption) + C (Coupon Loss)

Pricing formula needs essentially two inputs: Volatility σ and implied trigger level S*
