A question in the comments to my old post A Structural Model of Contingent Bank Capital led me to look up what Prof. George Pennacchi has been doing lately; together with Theo Vermaelen and Christian C. P. Wolff he has written a paper titled Contingent Capital: The Case for COERCs:

In this paper we propose a new security, the Call Option Enhanced Reverse Convertible (COERC). The security is a form of contingent capital, i.e. a bond that converts to equity when the market value of equity or capital falls below a certain trigger. The conversion price is set significantly below the trigger price and, at the same time, equity holders have the option to buy back the shares from the bondholders at the conversion price. Compared to other forms of contingent capital proposed in the literature, the COERC is less risky in a world where bank assets can experience sudden, large declines in value. Moreover, the structure eliminates concerns of an equity price “death spiral” as a result of manipulation or panic. A bank that issues COERCs also has a smaller incentive to choose investments that are subject to large losses. Furthermore, COERCs reduce the problem of “debt overhang,” the disincentive to replenish shareholders’ equity following a decline.

The basic justification for the COERCs is:

In contrast to the Credit Suisse coco bond [with accounting and regulatory triggers], the trigger is based on market value based leverage ratios, which are forward looking, rather than backward looking, measures of financial distress. It also means that at the time of the triggering event the stock price is known, unlike in the case of coco bonds with accounting based capital ratio triggers. As the trigger is driven by the market and not by regulators, regulatory risk is avoided. The conversion price is set at a large discount from the market price at the time of conversion, which means that conversion would generate massive shareholder dilution. However, in order to prevent this dilution, shareholders have an option to buy back the shares from the bondholders at the conversion price. In practice, what will happen is that when the trigger is reached, the company will announce a rights issue with an issue price equal to the conversion price and use the proceeds to repay the debt. As a result, the debt will be (almost) risk-free. In our simulations, we show that it is possible to design a COERC in such a way that the fair credit spread is 20 basis points above the risk-free rate. So although the shareholders are coerced to repay the debt, the benefit from this coercion is reflected in the low cost of debt as well as the elimination of all direct and indirect costs of financial distress. Although at the time of the trigger, the company will announce an equity issue, there is no negative signal associated with the issuance as the issue is the automatic result of reaching a pre-defined trigger.

Market based triggers are generally criticised because they create instability: bond holders have an incentive to short the stock and trigger conversion. Moreover, the fear of dilution may encourage shareholders to sell their shares so that the company ends up in a self-fulfilling death spiral. However, because in a COERC shareholders have pre-emptive rights in buying the shares from the bondholders, they can undo any conversion that is result of manipulation or unjustified panic. Moreover, because bondholders will generally be repaid, they have no incentive to hedge their investment by shorting the stock when the leverage ratio approaches the trigger, unlike the case of coco bonds where bondholders will become shareholders after the triggering event. The design of the contract also discourages manipulation by other bondholders. Bolton and Samama (2010) argue that other bond-holders may want to short the stock to trigger conversion, in order to improve their seniority. However, because the COERCs will be repaid in these circumstances such activity will not improve other bondholder’s seniority.

Further justification is given as:

Our objective is to propose an alternative, an instrument that a value maximizing manager would like to issue, without being forced by regulators. Companies are coerced to issue equity and repay debt by fear of dilution, not by the decision of a regulator. Imposing regulation against the interest of the bank’s shareholders will encourage regulatory arbitrage and may also reduce economic growth.6 If bankers, on the other hand, can be convinced that issuing contingent capital increases shareholder value, then any regulatory “encouragement” to issue these securities will be welcomed. Our proposal is therefore more consistent with a free market solution to the general problem that debt overhang discourages firms from recapitalizing when they are in financial distress. Hence the COERC should be of interest to any corporation where costs of financial distress are potentially important.

It seems like a very good idea. One factor not considered in the paper is the impact on equity investors.

Say you have an equity holding in a bank that has a stock price (and the fair value of the stock price) slightly in excess of the trigger price for its COERCs. At that point, buyers of the stock (and continuing holders!) must account for the probability that the conversion will be triggered and their will be a rights issue. Therefore, in order to avoid dilution, they must not only pay the fair market value for the stock, but they must also have cash on hand (or credit lines) available that will allow them to subscribe to the rights offering; the necessity of having this excess cash will make the common less attractive at its fair market value. This may serve to accelerate declines in the bank’s stock price.

It is also by no means assured that shareholders will be able to sell the rights anything close to their fair value.

A Goldman Sachs research report titled Contingent capital Possibilities, problems and opportunities is also of interest. Canadians panic-stricken by the recent musings in the federal budget (see discussion on April 1, April 2 and April 5) will be fascinated by:

Bail-in is a potential resolution tool designed to protect taxpayer funds by converting unsecured debt into equity at the point of insolvency. Most bail-in proposals would give regulators discretion to decide whether and when to convert the debt, as well as how much.

There is an active discussion under way as to whether bail-in should be a tool broadly applicable to all forms of unsecured credit (including senior debt) or whether it should be a specific security with an embedded write-down feature.

Naturally, this discussion is not being held in Canada; we’re too stupid to be allowed to participate in intelligent discussions.

As might be expected, GS is in favour of market-based solutions and consequent ‘high-trigger’ contingent capital:

Going-concern contingent capital differs substantially from the gone-concern kind. It is designed to operate well before resolution mechanisms come into play, and thus to contain financial distress at an early stage. The recapitalization occurs at a time when there is still significant enterprise value, and is “triggered” through a more objective process with far less scope for regulatory discretion. For investors to view objective triggers as credible, however, better and more-standardized bank disclosures will be needed on a regular basis. Because this type of contingent capital triggers early, when losses are still limited, it can be issued in smaller tranches. This, in turn, allows for greater flexibility in
structuring its terms.

When the early recapitalization occurs, control of the firm can shift from existing shareholders to the contingent capital holders, and a change in management may occur. The threat of the loss of control helps to strengthen market discipline by spurring the firm to de-risk and de-leverage as problems begin to emerge. As such, going-concern contingent capital can be an effective risk-mitigating tool.

GS further emphasizes the need to appeal to fixed income investors:

Contingent capital will only be viable as a large market if it is treated as debt

Whether “going” or “gone,” contingent capital will only be viable as a large market if it is treated as debt. This is not just a question of technical issues like ratings, inclusion in indices, fixed income fund mandates and tax-deductibility, though these issues are important. More fundamentally, contingent capital must be debt in order to appeal to traditional fixed income investors, the one market large enough to absorb at least $925 billion in potential issuance over the next decade.

Surprisingly, GS is in favour of capital-based triggers despite the problems:

A capital-based trigger would force mandatory conversion if and when Tier 1 (core) capital fell below a threshold specified either by regulators (in advance) or in the contractual terms of the contingent bonds. We think this would likely be the most effective trigger, because it is transparent and objective. Investors would be able to assess and model the likelihood of conversion if banks’ disclosure and transparency are enhanced. Critically, a capital-based trigger removes the uncertainty around regulatory discretion and the vulnerability to market manipulation that the other options entail.
…
Capital-based triggers are also vulnerable to financial reporting that fails to accurately reflect the underlying health of the firm. Lehman Brothers, for example, reported a Tier 1 capital ratio of 11% in the period before its demise – well above the regulatory minimum and a level most would have considered healthy. The same was true for Bear Stearns and Washington Mutual before they were acquired under distress. We think this issue must be resolved for investors to embrace capital-based triggers.

Fortunately there are several ways to make capital ratios more robust, whether by “stressing” them through regulator-led stress tests or by enforcing more rigorous and standardized disclosure requirements that would allow investors to better assess the health of the bank. Such standardized disclosures could relieve regulators of the burden of conducting regular stress tests, and would significantly enhance transparency. The value of stress testing and greater disclosures is one lesson from the financial crisis. The US Treasury’s 2009 stress test illustrates this point vividly. While not perfect, it offered greater
transparency and comparability of bank balance sheets than investors were able to derive from public filings. With this reassurance, investors were willing to step forward and commit capital. The European stress test proves the point as well: it did not significantly improve transparency and thus failed to reassure investors or attract capital.

That is the crux of the matter and I do not believe that the Gordian Knot can be cut in the real world. The US Treasury made their stress test strict and credible because it knew in advance that its banks would pass. The Europeans made their stress test ridiculous and incredible because they knew in advance that their banks would fail.

I liked their succinct dismissal of regulatory triggers:

While flexibility can be helpful, particularly given that no two crises are alike, recent experience shows that some regulators may be hesitant to publicly pronounce that a financial firm is unhealthy, especially during the early stages of distress. There is, after all, always the hope that the firm’s problems will be short-lived, or that an alternative solution to the triggering of contingent capital can be found. Thus a regulator may be unlikely to pull the trigger – affecting not only the firm and all of its stakeholders, but also likely raising alarm about the health of other financial firms – unless it is certain of a high degree of distress. By then, losses may have already risen to untenable levels, which is why this type of trigger is associated with gone-concern contingent capital.

GS emphasizes the importance of the indices:

The inclusion of contingent capital securities in credit indices will also be an important factor, perhaps even more important than achieving a rating. This is because the inclusion itself would attract investors, who otherwise might risk underperforming benchmarks by being underweight a significant component of the index. Credit indices currently do not include mandatorily convertible equity securities, although they can include instruments that allow for loss absorption through a write-down feature. This again contributes to the appeal of the write-down feature (rather than the simple conversion to equity) to most fixed income investors. If contingent capital securities were included in credit indices, this addition would be likely to drive a substantially deeper contingent capital market.

Here in Canada, of course, the usual benchmark is prepared by the TMX, which the regulators allowed to become bank-owned on condition that it improved the employment prospects for regulators. It’s a thoroughly disgraceful system which will blow up in all our faces some days and then everybody will pretend to be surprised.

GS is dismissive of regulatory triggers and NVCC:

A discretionary, “point of non-viability” trigger would likely be attractive to many regulators as it helps them to preserve maximum flexibility in the event of a financial crisis. This can be useful given that no two crises are exactly alike. It could also allow regulators to consider multiple factors – including the state of the overall financial system – when making the decision to pull the trigger. Discretion also gives regulators the opportunity to exercise regulatory forbearance away from the public spotlight.

Yet we believe this preference for discretion and flexibility makes it difficult for regulators to meet one of their most important – yet mostly unspoken – goals, which is to develop a viable contingent capital market. Regulators have certainly solicited feedback from investors, but some seem to believe that simply making contingent capital mandatory for issuers means that investors will buy them. However, from conversations with many investors, we believe that regulators may need to move toward a more objective trigger; if not, the price of these instruments may be prohibitive.

There is another set of participants in a potential contingent capital market: taxpayers. Regulators represent taxpayers’ interests by promoting systemic stability and requiring robust loss-absorption capabilities at individual banks. But the interests of regulators and taxpayers may not always be fully aligned. If taxpayers’ principal goal is to avoid socializing private-sector losses, and to prevent the dislocation of a systemic crisis even in its early stages, then they should want a stringent version of contingent capital – one that converts to equity at a highly dilutive rate, based on an early and objective trigger. The discretion and flexibility inherent in regulatory-triggered gone-concern contingent capital may have less appeal to taxpayers. From their standpoint, gone-concern contingent capital might well have allowed a major financial firm to fail, causing job losses and other disruptions across the financial system. Taxpayers may find the potential risk-reducing incentives created by going-concern contingent capital to be a more robust answer to the problem of too big to fail.

Goldman’s musings on investor preference can be taken as an argument in favour of COERCs:

Traditional fixed-income investors will likely want contingent capital to have a very low probability of triggering, which leads them to prefer an objective, capital-based and disclosure-enhanced trigger. Many investors have indicated their concerns about the challenges of modeling a discretionary trigger: it is very difficult to model the probability of default, the potential loss given default or even the appropriate price to pay for a security that converts under a discretionary and opaque process. Greater transparency is a prerequisite for a capital-based trigger to be seen as credible by investors, because they will need to have greater confidence that banks’ balance sheets reflect reality. We also believe that investors would be more likely to embrace a capital-based trigger if the terms were quite stringent, thereby lowering the probability of conversion.

Under pressure from the Swiss bank regulator Credit Suisse is issuing High-Trigger CoCos:

Credit Suisse today announced a number of measures to accelerate the strengthening of its capital position in light of the current regulatory and market environment. An immediate set of actions will be implemented to increase the capital by CHF 8.7 billion. Additional capital actions and earnings related impacts are to increase the capital by a further CHF 6.6 billion by year-end 2012.

The measures will result in an expected end-2012 look-through Swiss Core Capital Ratio of 9.4%, compared to the 2018 requirement of 10%. Look-through Swiss Core Capital includes look-through Basel III Common Equity Tier 1 (CET1) and existing participation securities (“Claudius notes”) that qualify as part of the Swiss equity requirement in excess of the 8.5% Basel III G-SIB Common Equity Tier 1 (CET1) ratio.

The measures will result in an expected look-through Swiss Total Capital Ratio of 10.8% at end 2012. This broadly compares to the figure of 5.9% calculated by the Swiss National Bank (SNB) at the end of 1Q12 and published in its 2012 Financial Stability Report. Look-through Swiss Total Capital includes look-through Basel III CET1 and the participation securities (“Claudius notes”). Additionally it includes the Group’s Buffer Capital Notes (“CoCos with high trigger”).

There are no details available on the projected notes, but they have some Tier 2 Buffer Capital Notes outstanding.

For example, there is a USD 2-billion issue of 7.875 per cent. Tier 2 Buffer Capital Notes due 2041:

Interest on the BCNs will accrue from and including 24 February 2011 (the ‘‘Issue Date’’) to (but excluding) 24 August 2016 (the ‘‘First Optional Redemption Date’’) at an initial rate of 7.875 per cent. per annum, and thereafter at a rate, to be reset every five years thereafter, based on the Mid Market Swap Rate (as defined herein) plus 5.22 per cent.
…
If a Contingency Event or a Viability Event (each as defined herein) occurs, the BCNs shall, subject to the satisfaction of certain conditions, mandatorily convert into Ordinary Shares (as defined herein) which shall be delivered to the Settlement Shares Depository (as defined herein) on behalf of the Holders, as more particularly described in ‘‘Terms and Conditions of the BCNs—Conversion’’. In the event of a Contingency Event Conversion (as defined herein), such Ordinary Shares may, at the election of CSG, be offered for sale in a Settlement Shares Offer as described herein.
…
Contingency Event means that CSG has given notice to the Holders that CSG’s Core Tier 1 Ratio (prior to the Basel III Regulations Date) or the Common Equity Tier 1 Ratio (on or after the Basel III Regulations Date) is below 7 per cent. as at the date of the financial statements contained in a Quarterly Financial Report and that a Contingency Event Conversion will take place.
…
Viability Event means that either: (a) the Regulator has notified CSG that it has determined that Conversion of the BCNs, together with the conversion or write off of holders’ claims in respect of any other Buffer Capital Instruments, Tier 1 Instruments and Tier 2 Instruments that, pursuant to their terms or by operation of laws are capable of being converted into equity or written off at that time, is, because customary measures to improve CSG’s capital adequacy are at the time inadequate or unfeasible, an essential requirement to prevent CSG from becoming insolvent, bankrupt or unable to pay a material part of its debts as they fall due, or from ceasing to carry on its business; or (b) customary measures to improve CSG’s capital adequacy being at the time inadequate or unfeasible, CSG has received an irrevocable commitment of extraordinary support from the Public Sector (beyond customary transactions and arrangements in the ordinary course) that has, or imminently will have, the effect of improving CSG’s capital adequacy and, without which, in the determination of the Regulator, CSG would have become insolvent, bankrupt, unable to pay a material part of its debts as they fall due or unable to carry on its business.
…
The BCNs will be converted into a number of Ordinary Shares determined by dividing the principal amount of each BCN by the Conversion Price in effect on the relevant Conversion Date. ‘‘Conversion Price’’ means (i) at any time when the Ordinary Shares are admitted to trading on a Recognised Stock Exchange, in respect of any Conversion Date, the greatest of (a) the Reference Market Price of an Ordinary Share on the fifth Zurich Business Day prior to the date of the relevant Contingency Event Notice or, as the case may be, the Viability Event Notice translated into United States dollars at the Exchange Rate, (b) the Floor Price on the fifth Zurich Business Day prior to the date of the Contingency Event Notice or, as the case may be, the Viability Event Notice; and (c) the nominal value of each Ordinary Share on the Share Creation Date (being, at the Issue Date, CHF 0.04) translated into United States dollars at the Adjusted Exchange Rate, or (ii) without prejudice to ‘‘Takeover Event and De-listing’’ below, at any time when the Ordinary Shares are not admitted to trading on a Recognised Stock Exchange by reason of a Non-Qualifying Takeover Event or otherwise, the greater of (b) and (c) above.

Very good. There’s a high trigger and conversion at market price. The part I dislike is that the conversion trigger is a regulatory ratio – we found during the crisis that regulatory ratios aren’t worth much in the course of a panic. Still – much better than anything we’re ever likely to see in Canada!

Following the finalization of the OSFI NVCC Advisory and basically simultaneously with the Review-Negative slapped on NVCC-eligible extant preferreds, DBRS has announced that it:

has concluded today that it expects it can rate Canadian subordinated debt with a non-viability contingent capital clause (sub debt NVCC) and Canadian preferred shares with a non-viability contingent capital clause (pref NVCC) following the review of the Office of the Superintendent of Financial Institutions Canada (OSFI) Advisory on Non-Viability Contingent Capital, issued on August 16, 2011 (NVCC Advisory).

In this document, all references to non-viability contingent capital (NVCC) instruments are based on our expectations that non-viability (as determined by OSFI) is the only contingent event, that the contingent event triggers permanent conversion to common equity and that over time, as NVCC becomes the major instrument with respect to subordinated debt and preferred shares, any trigger event for sub debt NVCC holders would cause these holders to become meaningful owners of the bank in question. These considerations are also consistent with our ability to rate the NVCC instruments. According to DBRS criteria, the triggers are well defined and permit an assessment of the risks.

Both the sub debt NVCC and pref NVCC ratings will have wider notching, based on the global standard notching for preferred shares, because of additional risk associated with tripping the trigger. The expected losses resulting from tripping the trigger would have an impact on the relative rating of sub debt NVCC and pref NVCC. As guidance, sub debt NVCC will likely be rated no higher than the standard rating for preferred shares and the pref NVCC will likely be rated one notch below the standard rating for preferred shares.
…
For clarity, global standard notching for preferred shares means the starting point for notching preferred share ratings is the intrinsic assessment (IA) rating rather than the final senior debt rating, and the degree of notching from the IA rating to the preferred share rating widens to reflect our perception of the increased risk in these capital instruments. The base notching policy is three notches for AA, four notches for “A” and five notches for BBB and lower IA ratings. Note that when DBRS initiated the criteria on June 29, 2009, most banks in Canada had their preferred share ratings downgraded to only one notch above the global standard notching for preferred shares
…
DBRS has determined that the likelihood of tripping the trigger event (i.e., non-viability as determined by OSFI) would be very hard or remote. DBRS’s decision was based on the assessment of the criteria to be considered in triggering conversion of NVCC instruments that was spelled out in the NVCC advisory by OSFI. Lower-rated banks suggest an increased probability of conversion as a result of tripping the trigger given the greater need for a bank to generate regulatory capital. This would result in higher notching from the intrinsic assessment, as set out in the DBRS methodology Rating Bank Preferred Shares and Equivalent Hybrids. As such, both the sub debt NVCC and pref NVCC ratings would be tied to the preferred share rating of the bank.

The expected losses as a result of the conversion would affect the rating for sub debt NVCC relative to pref NVCC. It is the economic entitlement each receives post-trigger that is the significant factor in the relative ratings as opposed to the host security’s pre-trigger features. This economic entitlement can be assessed only after terms are provided in a contractual agreement between the issuing bank and the purchaser.
