Rumour has it...

Present and future

A few thoughts from SCI to SCIs

Welcome to the first issue of Structured Credit Investor. Normally this section will, as its name suggests, be the place to come for rumour and gossip - the remainder of SCI will deal in facts, however.

'Rumour has it...' will usually be written by a member of the editorial team, but will occasionally be written by a guest contributor - so look out to see if you notice the join. In any event, SCI welcomes all contributions from readers, either targeted at the 'Research Notes' section or more general contributions relating to debates in the structured credit markets. Please feel free to contact us via the website.

One debate that continues to run is when the credit cycle will turn and spreads start a long-term widening trend as a consequence? The increasing weight of erudite research being produced by banks in recent weeks suggests this is unlikely to happen in the near term, with spreads being held in by huge volumes of buying on behalf of a massive CDO pipeline - which again looks stacked to the roof for next month.

At the same time, you the investors seem decided on the issue even further into the future. Given the growing number of range accrual products that many of you are buying, clearly the belief is that credit spreads broadly are not going to blow-out dramatically for a while.

Of far greater concern to the large number of investors that we talk to - particularly those outside the 'fast money' category and usually those newer to credit derivatives - are hidden costs. While all acknowledge that the market has improved in this respect, the thought still remains for many investors: "...how and by how much."

Such worries are unlikely to disappear soon with continuing accusations of front-running cropping up from time to time - however unfounded they may be - and the knowledge that the hefty losses incurred by some dealers in May 2005's correlation crisis and quietly absorbed into reserves, may well have to be repaid at some point. As a result, transparency is an issue we will undoubtedly be returning to on a regular basis.

In the meantime, 'buyer beware' must remain the watchwords - or, as they used to say in Hill Street Blues and currently on advertising hoardings across London, "let's be careful out there".

Succession fears allayed

Potential tax-free spin-offs appear limited



Investor concerns about the possible acceleration of succession events affecting the credit default swaps (CDS) markets were allayed somewhat last week. At the same time, the trading opportunities brought about by the CDS price volatility generated by such events will remain.

Research from Barclays Capital concludes that there may be less to fear from potential succession events than had been thought. "We don't think, at least in the context of a tax-free spin-off, that you are going see several other iterations of Alltel," says Matthew Mish, credit derivatives strategist at Barclays Capital in New York.

While such news is welcome for long-term investors, it could conceivably be less good for trading accounts. Mish suggests that there will still be opportunities, however. "If there is repricing in the market in the same way as we saw to some extent with First Data, for example, I expect there will be opportunities for investors amid uncertainty, that is, perhaps, unfounded," he says.

Tax-free spin-offs involving debt-for-debt exchanges have added a new wrinkle to investor concerns over CDS succession events, highlighting unique risks for sellers of protection. This stands in contrast to the early-2006 market perception of risks related to spin-offs and other capital structure transformations, wherein most risk resided with protection buyers.

In recent instances, however, an exchange of bonds transpired through tax-free spin-offs. Such transactions have resulted in changes to CDS reference entities and pushed 5-year CDS valuations significantly wider.

Barclays Capital's research involved the creation of a framework to evaluate spin-offs that have already been announced and, significantly, screens a range of industry sectors for companies that it believes could, in theory, initiate spin-offs over the longer term.

Mish explains: "We then evaluated the likelihood of a succession event triggered by a debt for-debt exchange using our framework. Our guidelines eliminate most candidates under consideration, suggesting succession events associated with spin-offs are not likely to be widespread."

Investor response to the research has been positive. "In general we have received positive feedback and people have been pretty receptive to the idea of a framework. It helps narrow down the list of candidates which can then be examined in more detail," says Mish.

Indeed, as one fund manager says: "It is always welcome to receive reassurance that these type of issues could not happen to just anyone, but are constrained to fairly controllable or manageable universe."

Tax-free spin-offs are a catalyst for debt-for-debt exchanges because exchanges allow companies to potentially extract value above the tax basis while retaining their tax-free status. Debt-for-debt exchanges involving greater than 25% but less than 75% of a reference entity's bonds or loans will result in a 50/50 split of the CDS contract. This can drastically change CDS valuation if the parent and Spin-off company differ in credit quality, which is often the case when spun-off assets are levered up.

Transatlantic shift

Disparity expected in the target market for US and European LCDS indices

As talks continue among dealers over the make-up of proposed new credit default swap indices referencing their respective leveraged loan markets either side of the Atlantic, it appears the focus of the new products will - initially at least - diverge. LCDX, the new North American Leveraged Loan index - which is scheduled for launch in or after October - is understood to be being designed to facilitate standardised tranches in the same way as the CDX tranche market, thereby broadly targeting structured credit investors.

It is expected that LCDX will reference between 75-100 underlying loans, selected by liquidity in the same manner as the CDX Investment Grade Index, which is enough to provide sufficient diversity for tranching. The index will also be a non-cancellable five year bullet that will trade on price and will almost certainly be cash rather than physically settled. So, LCDX will not exactly reflect the underlying loan market and is therefore likely to be less appealing to the existing single name cash investor base.

"Designing LCDX to appeal to structured credit investors is a bold move and is in contrast to other index markets such as the ABX Home Equity index and the planned European Leveraged Loan index, iTraxx LevX, which are structured in ways that reflect the underlying cash markets, which means that they do not necessarily facilitate structured credit investments," says Michael Hampden-Turner, Structured Credit Strategy at Royal Bank of Scotland.

LevX is scheduled to be launched later this year, but precise details of the index constituents have not yet been confirmed. David Mark, CEO of the International Index Company, nevertheless points out that it will initially be targeted at market participants and will therefore reflect the current make up of the European market. He says: "Obviously, as those participants change the index will evolve alongside the market."

As Pierre Emmanuel Juilliard, head of Structured Finance, AXA IM, explains, there are still challenges in Europe even though the leveraged loan market is now big in volume terms, having grown exponentially in recent years - the number of issuers is still smaller than in the US. Equally, the US has benefited from the earlier introduction of cash indices, making the market more liquid and accessible to a wider range of investors.

Consequently, Juillard adds: "I expect that LevX will be more for interbank loan participants than structured credit investors more broadly, while the reverse is likely to be true with the US index. However, the European index will, sooner rather than later, become the way for a broader range of investors to have access to the asset class, because we are seeing more and more demand from large institutions to have access to leveraged loans."

The Structured Credit Interview

Building on a strong platform

This week, David Littlewood, director and one of the founding partners of Cairn Capital, responds to SCI's questions

David Littlewood

Q: When, how and why did your firm become involved in the structured credit markets?
A: Cairn Capital was formed in 2004 by a group of market professionals who had many years of experience across the credit markets, with the aim of focussing that experience from an independent platform for the benefit of investors. We all had successful careers but the attraction for us was creating something that we thought the market needed in an area that we found to be stimulating and enjoyable, and where our backgrounds were totally relevant to what we wanted to do. We haven't looked back since!

The idea was that as a result of the incredible velocity at which the credit markets have evolved in the past few years it is very, very difficult for a firm to fully participate in those markets if it is not an investment bank with all the technology, technical skill-set and so on that that entails. If you are a 'normal' investor you are unlikely to be able to invest a huge amount of resource and make credit a core part of your business strategy, so you need to outsource and pay somebody else to do that and manage credit for you.

This is where we come in - we are the participant in the credit market that investors can look at as working for them and having the full skill-set on an independent platform that is on a par with that of an investment bank. We made a fundamental decision from day one that we would operate across the credit markets in their broadest sense.

What investors want is somebody that they can rely on consistently to be a performer right across the board and someone who can offer many different types of product. Conversely, what investment banks want is clients who are active across the credit markets, who buy up and down the capital structure and participate irrespective of what the current credit cycle is doing. Our success and leverage with the investment banks is driven by how attractive we are as a client to them and that translates into a better service for our investors. What that should mean is that we can deliver good products for them, we can get great execution and we can get great allocations.

Q: In your view, what has been the most significant development in the credit markets in recent years?
A: For me, first and foremost has been the acceptance of credit as an investment medium across a very, very broad spectrum of investors. The fact that you now have such a wide variety of investors from insurance companies, to hedge funds, to asset managers to family offices involved in this space gives it huge impetus to develop and to continue to do so.

Q: How has this affected your business?
A: It has been the key driver behind our business, because it's the developments in the credit markets that have given us the opportunity to participate in this marketplace in the way that we had originally envisaged. It means that there are many different products that we can offer to investors around many different credit asset classes.

The growth in the use of the indices and index products, for example, means that we are very comfortable with the liquidity in the market place and a very active trader in the market. At the same time, it has meant that we have also had to keep investing in systems and hiring the right sort of personnel to keep pace with the speed of the development of the market, but the transaction opportunities that we have allow us to do that.

Q: What are your key areas of focus today?
A: Our key areas of focus today are corporate credit, asset-backed securities and European leveraged loans. We have been very active in doing CDOs, CPPI products and also fund products in all of these areas.

We like to run funds businesses in a particular asset class alongside CDO and CPPI because we think the synergies between how you manage a fund and the skill-set you need to have to manage a fund is very relevant to how you have to manage some of the CDO and CPPI products in today's marketplace. This combination also means that we are constantly active and therefore always in the market flows and know what's going on.

Q: What is your strategy going forward?
A: Primarily it is to continue to build a credit institution. We have grown slowly and carefully through building the right infrastructure and hiring the right people, because our intention is that we are here for the long term. In future, we want to build on the deals we have done and we want to increase the number of deals we do, and as we see opportunities arise we will add different activities to the platform.

Q: What major developments do you need/expect from the market in the future?
A: In terms of needs, I think we are pretty happy with the way the market is currently, but obviously there are always some 'nice to haves'. We would like to see the market develop more in the leveraged loan space for credit default swaps - I think more work could be done there. Equally the universal acceptance of an established loan index would be very welcome.

As for what to expect, it is probably more a case of continuing to expect the unexpected. We have seen some really quite surprising events over the last couple of years that have turned out to benefit the market. The correlation crisis of last May, for example, was very much a case of taking something that had been theorised about for a long time and then the market actually instilled some discipline into it by showing that it actually doesn't matter what models you come up with because the market is supply and demand driven and that will always rule. So we expect and hope for a continuation of exciting times and the opportunities that they will bring.

Provider Profile

"The more complex the problem, the more comfortable we are"

Profiling Misys Summit

In this week's Provider Profile we talk to Dan Cohen* and Emmanuel Nusimovici** from Misys Banking Systems.

Misys Summit, part of the Misys technology empire since 1997, attributes its reputation as a star performer in the credit derivatives sector to the fact that its roots are in derivatives software, in contrast to software developers in other markets that have been attracted by the profits being made in derivatives technology and wanted to join the party as a result.

That's not to say it's only a derivatives technology provider: Misys Summit boasts a platform to accommodate all customer profiles, according to Dan Cohen, Product Manager for Misys Summit.

Dan Cohen
"Since the 1990s we've built a multi-coverage, cross-asset product, from front to back office integrating many instruments, including exotic products." To underline where the firm's roots lie, however, he adds: "The more exotic the product, the more success we have with customers."

Taking advantage of Microsoft architecture, Misys Summit developed a .NET client to enable layers of product to be built up in the back-end, while a smart client sits at the front-end. The result is "a versatile application in which new software can be added for new asset classes without the need for extra programming", says Emmanuel Nusimovici, Product Manager with responsibility for Misys Summit's Credit Derivatives product.

Called Summit MUST (Multiple Underline Structured Trade), the module was developed alongside HSBC. MUST satisfied Misys Summit's objective of providing a single integrated trading and STP environment for the trading of standard instruments and structured products. Cohen sees MUST as affirming the company's "market leadership in complex structured products".

Recognising the need to constantly evolve their market offering, the software has been completely redeveloped since 2001, with a front-end that hosts all applications in real-time – including several graphical components – and added features on the client's screen such as trade blotters. And all this is complemented by a "true STP capability".

Misys Summit has tracked the development of the structured credit sector closely from the early days in the mid- to late-1990s when it supplied solutions for processing trades that by today's standards must seem like very simple structures, such as total return swaps and CDS. The firm was therefore well positioned to be one of the first software houses to recognise the increasing importance of the profitability of the credit derivatives market to structured product desks in London and New York.

Believing that it was now a "pioneer" in credit derivatives technology, the firm saw that more sophisticated technology would be necessary to accommodate the inevitable rise in trade volumes the market would see. "We have always believed that market volumes would increase," comments Nusimovici. "So we sought to develop a best of breed product to cope with increasing trade volumes". MUST, released in 2004, has now been installed in many customer sites globally and has been chosen as the technology on which to base the company's latest credit derivatives module; providing "a highly adaptive platform that can handle a large volume of CDS and the like, and also cope with the more complex structured instruments" claims Cohen.

Misys Summit will release a new version of its credit derivatives module later this summer, specially designed for correlation trades. Correlation is in fact one of the areas that the firm believes will see the most activity in the future.

Additionally, issues such as the rising volume of trade flow and the sheer complexity of trades being seen are, it believes, a pressing concern for banks right now. Such is the pace of development that "eventually we will have CDS on everything", comments Nusimovici.

Complexity issues concern Cohen too: "Cross asset hybrid products such as risky swaps" present the market with a further IT challenge, implying a need for banks to redesign portfolio tools to deal with these complex structured products. Also required is an efficient way to integrate the "large populations of market data in the CDS and CDO market", says Nusimovici.

But which solutions solve these technological headaches? Cohen sees a desire within the trading community to move away from stand-alone solutions: these days banks prefer to deal with the complexity of a multi-asset trading infrastructure comprising of, for example, equities, interest rates, bonds and credit derivatives on a single platform. It is handy therefore that Misys supplies such a solution – and is viewed by customers as a "continuum" to their growth needs, claims Cohen.

And as structured credit trade volumes grow, so too does the need to price these mathematical works of art. However, notes Cohen, "there's a lot of research going on (into pricing models) but no-one is yet saying they're good enough".

Principally when pricing a structure there is the well-known conundrum of precision versus speed to consider before proceeding. It is important to get an accurate price to a client and to do it quickly, but these two needs don't necessarily make easy bed fellows. The solution, according to Misys, is grid computing, the process by which the power of an entire enterprise's available IT infrastructure can be harnessed by an application, such as pricing software, to dramatically speed the process up.

This offers the "brute force" solution to pricing problems, according to Cohen. He continues: "Grid is a good solution when you have, for instance, 135 issues in a bespoke basket. The need to analyse risk and gather data on sensitivity testing can be performed efficiently by grid computing." Accordingly, some of Misys Summit's clients are now using grid computing across the board.

Leadership in market technology is a key factor for Misys Summit's next phase of development, according to Cohen. The firm's objective is to lead the way in providing structuring desks with the technology to develop new products with the speed and flexibility they'll need in the coming years, while also recognising that the buy-side – hedge funds in particular – are often the pioneers in developing new structured credit products.

Providing the buy-side with solutions to move away from a predominance of spreadsheet-based applications is also a goal for Misys Summit, according to Nusimovici. It is here where there are "so many instruments traded and so much innovation seen" that it is "dangerous for risk in (that part of) the hedge fund market not properly invested in technology".

The firm's philosophy – of partnering with customers for the long term – is paying off well. Two major banks are co-developing the next generation of "cutting edge" applications with Misys Summit, according to Cohen, enabling the company to further enhance its reputation – and its excellent customer satisfaction ratings. "Banks are used to buying software now, and very little in-house build is being seen; the markets are evolving so fast that banks have to buy from outside to keep up," notes Nusimovici.

Misys Summit clearly knows its patch well and is determined to keep its position of leadership, so long as clients keep coming up with the complex problems necessary to keep them in their comfort zone.

* Dan Cohen has 20 years experience in building and implementing Capital Markets software. Starting out in developing a Eurobonds trading system he joined Quotient in 1990. This firm subsequently merged with Summit and over the years he has been responsible for Technical services, client developments and some strategic enhancement projects including bonds, FX, back office and accounting. Cohen is now product manager for the Misys Summit product range.

** Prior to joining Misys, Emmanuel Nusimovici ran his own consulting firm for 5 years, servicing banks, asset managers and financial institutions such as Credit Lyonnais or Natexis in the field of capital markets, and also servicing software vendors like Calypso. In particular, Nusimovici was involved in the initial design and presales of Calypso's Credit Derivatives module. From 1994 to 1999, he was the Head of Presales for southern Europe of one of Summit's long time competitors: Infinity. Prior to this, Nusimovici started his career as an FX Option Trader for 3 years at Societe Generale in Paris and New York.

News Round-up

Fitch launches stability scores

A round-up of all the week's structured credit news

Fitch launches stability scores
Fitch Ratings has launched a set of stability scores for synthetic CDOs that are designed to provide a better understanding of the prospective stability of ratings assigned to CDO tranches by indicating the propensity of a tranche to retain its original rating over a period of one year from closing. The move follows a consultation period with market participants.

The key aspects to rating stability include the level of excess credit enhancement, underlying diversity, barbelling of underlying credit, level of overlap in CDO-squareds and term of the deal. The findings were made possible by simulating the possible rating outcomes at a given point in the future after accounting for expected portfolio performance.

"We received overwhelming support from investors to apply this research in a way that provides a greater level of risk transparency to synthetic CDOs being issued," says Richard Gambel, Managing Director, Fitch Ratings. "The product is unique because it is forward looking and it takes into account all transaction and portfolio features, not just the level of excess credit enhancement."

Central to the delivery of the analysis was the concept of a stability score to put the measure of stability into an absolute, as well as relative context. Stability scores range on a scale of ST1 to ST3, with the first indicating a minimum one-year theoretical estimate of stability of 90%, the second between 90% and 80%, and the third less than 80%.

For the moment, stability scores will be generated for AAA tranches of corporate CDOs, but Fitch plans to expand them to lower rated tranches and to CDOs that reference ABS in the future.

Meanwhile, Fitch has released an updated version of its VECTOR default model in Beta format. The changes include an updated user interface, together with other features that focus on ease of use, including an automated data loader for corporate reference entities. The development of the new version includes a review of the entire assumption set, with a focus on both updating assumptions to account for additional data and to improve the integrity of the relationship between these assumption sets.

The new version also includes a revised framework for the analysis of emerging market assets in internationally-rated deals. The proposed approach puts greater weight on regional and country concentrations when determining asset correlation, rather than on industry concentrations.

Fitch's fundamental credit view has not changed, despite the comprehensive updating of assumptions. For the vast majority of Fitch-rated CDOs, the model changes don't indicate any difference in the ratings of the liabilities. But for short-dated transactions, the new model tends to take a harsher view - although this is expected to have a greater impact on the agency's view as transactions season, rather than at inception.

Markit brings standardised ABCDS payment calculations
Markit Group has launched Reference Cashflow Database (RCD) - standardised payment calculations for CDS on ABS in a bid to facilitate settlement in the rapidly growing sector.

While outstanding contracts in the single-name and index markets now total around US$175bn and an estimated US$5bn contracts trade every week, further growth in the single-name sector has been dampened by settlement. ABCDS have a pay-as-you-go structure, in which payment shortfalls are calculated on a monthly basis. But availability of data for the required calculations remains poor and the calculations themselves are complex, with the documentation open to different interpretations.
RCD holds information on almost 15,000 ABS securities.

Legislation broadens ability to market CDOs to pension funds
The US Congress has passed pension reform legislation (the Pension Reform Act) that significantly relaxes the rules governing when ABS - including CDOs and CMBS - may be offered to investors holding certain types of retirement plan assets. Compliance with its stringent fiduciary and prohibited transaction rules has historically made issuance under ERISA impractical for most securitisation issuers.

One regulatory exception (known as the Significant Participation Exception) relied on by issuers of either below-investment grade securitisations or those that are not characterised as debt for tax purposes applies if an issuer does not have 'significant participation' by 'benefit plan investors'. Under current regulations, the definition of 'benefit plan investor' includes foreign plans, government plans and insurance company general accounts, as well as ERISA plans and plans subject to Section 4975 of the Code. The difficulty in tracking holders of securitisations that are held in global form has meant that most issuers relying on the Significant Participation Exception either prohibit ERISA investors or prohibit all benefit plan investors.

In a new definition of 'plan assets', the Pension Reform Act revises the 'significant participation' exception to limit the definition of 'benefit plan investors' to include only those investors subject to ERISA or Section 4975 of the Code. It is also expected that many hedge funds that previously didn't satisfy the Significant Participation Exception will now satisfy the requirements of the exception.

FNX releases Sierra Treasury Select trading platform
FNX Solutions has launched Sierra Treasury Select, a cross-asset trading and processing solutions platform for regional banks and corporate treasuries. The front-to-back solution provides enhanced functionality for multiple asset classes including credit derivatives.

Research Notes

Synthetically managing bond portfolios

Replicating bond indices using credit derivatives

Dominic Kini, Quantitative Credit Strategist at ABN AMRO, and Gregorios Venizelos, Credit Derivatives Strategist, at ABN AMRO, explain the benefits and mechanics of bond index replication.

This article focuses on a low cost, highly liquid synthetic replica of the iBoxx EUR Corporates Index constructed using interest rate swaps and iTraxx Europe. We first described such a structure last year in our "iTraxx: tracking down iBoxx" publication dated 25 October 2005. Since then, tracking error has fallen slightly and we show the bulk of it is due to the basis between CDS and bonds. This should increase confidence in using the replica to manage bond portfolios.

As was the case last October, we construct a synthetic replica of the iBoxx EUR Corporates Overall bond index out of a portfolio of interest rate swaps and a long risk position in the on-the-run 5y iTraxx Europe (and optionally 10y iTraxx Europe). We rebalance at the end of every month to capture the change in composition of the bond index. The idea is that the interest rate swaps replicate the interest rate exposure of the bond index, and the iTraxx position captures the credit exposure of the bond index.

The benefit of the synthetic replica is that it is much more liquid and much easier to short than the bond index. We construct the synthetic replica out of seven interest rate swaps which can be transacted at or near mid market, and the iTraxx Europe which trades with a bid/offer spread of 0.25bp (at least for the 5y). In contrast, the bond index had 798 bonds at the start of July 2006. These bonds are of varying liquidity and difficult or impossible to short.

Thus the synthetic replica allows benchmarked investors to:
- Quickly ramp up bond portfolios
- Hedge bond portfolios in a cost-effective way
- Construct a platform on which active strategies can be overlaid.

Inevitably the synthetic replica will have a tracking error to the bond index but investors are effectively paying tracking error in order to receive liquidity.

Our sample starts on 21 June 2004 and we have extended it from 6 October 2005 to 7 July 2006. Our broad conclusions are:
- Tracking errors have fallen since our last publication but are broadly comparable.
- We continue to recommend using a combination of interest rate swaps plus 5y iTraxx Europe which achieves an excess return of 34.8bp (up from 18.4bp), a daily tracking error of 50.4bp (down from 58.7bp), and a weekly tracking error of 47.1bp (down from 52bp).
- Weekly tracking errors are lower than daily tracking errors (correcting an error in our earlier publication).
- Adding a combination of 5y and 10y iTraxx Subordinated Financials reduces the daily tracking error to 48.8bp and the weekly tracking error to 43bp.
- The bulk of the tracking error is due to the basis between CDS and bonds. A smaller amount is due to the skew i.e. the difference between the theoretical spread of the iTraxx Europe calculated from its underlying constituents and its actual traded spread. Almost none, however, is due to the difference in constituents and weights between the iTraxx Europe and the iBoxx EUR Corporates Overall, as we show later.

We note that our methodology is equally applicable to other bond indices, for example the Lehman or Merrill indices. We also highlight our "iBoxx EUR Monthly: On the right track" publication dated 28 April 2006 where we look at replicating the iBoxx EUR Corporates Overall using a small subset of bonds. While we achieve a tracking error of about 18bp with 60 bonds, such a portfolio will inevitably be much less liquid than the synthetic replica we describe in this document.

Results
We show our results in table 1 below, covering the period from 21 June 2004 to 7 July 2006.

"EUR interest rate swaps" refers to using just interest rate swaps to replicate the iBoxx EUR Corporates Overall, and not using any iTraxx exposure. Because this approach omits any credit exposure, we see that it underperforms the bond index over this period. Adding iTraxx exposure both increases the excess return and reduces the tracking error, as expected.

"IRS + 5y iTraxx Europe intrinsic" and "IRS + 5y, 10y iTraxx Europe intrinsic" have been calculated using the theoretical value for iTraxx based on its underlying constituents. "IRS + 5y iTraxx Europe traded" and "IRS + 5y, 10y iTraxx Europe traded" have been calculated using the actual traded value for iTraxx. We see that the daily and weekly tracking errors are higher if we use the traded value of iTraxx and thus a portion of the tracking error is due to the skew i.e. the difference between the theoretical fair value and actual traded value of the 5y and 10y iTraxx Europe. (The skew arises because the 5y and 10y iTraxx Europe are much more liquid than their 125 underlying constituents.)

Adding 10y iTraxx Europe makes very little difference to the tracking error. Therefore, we continue to recommend using a combination of interest rate swaps plus 5y iTraxx Europe to replicate the iBoxx EUR Corporates Overall and our core replication method is highlighted in bold in the table above.

We note that the weekly tracking errors are all lower than the daily tracking errors (this corrects an error in our earlier publication). This is good, as it suggests that mean reversion removes some of the daily tracking error.
The excess returns have all increased since the last publication, due to the recent outperformance of CDS versus bonds. Ideally we would like an excess return closer to zero, since it would reduce the cost of shorting the synthetic replica.
Over the period from 21 June 2004 to 7 July 2006, we compare the total return of iBoxx EUR Corporates Overall to the total return of interest rate swaps plus 5y iTraxx Europe intrinsic and traded in chart 2 and 4 below. We see that the synthetic replica tracks the bond index very closely, though it has recently outperformed. In charts 3 and 5, we show the daily excess returns i.e. how much each day the synthetic replica outperforms the bond index. The daily tracking error is the annualised volatility of these excess returns, and we see that the traded excess returns are more volatile than the intrinsic excess returns.

We have made corrections to the CDS data used to value iTraxx since the last publication on two days (8 July 2004 and 23 August 2004). Four spikes remain, two at year end and two at half year end. These spikes are caused by the bond index and iTraxx Europe behaving differently on these days. The year end spikes are probably caused by limited liquidity on these days. The half year end spikes may be caused by portfolio valuations distorting the market on these dates. If we remove the spikes in the "IRS + 5y iTraxx Europe intrinsic" case above, the daily tracking error falls by 3.8bp and the weekly tracking error by 0.5bp. We leave the spikes in the dataset when valuing in the traded case, since in practice it is difficult to avoid spikes like this.

We show the 22 and 66 trading day (i.e. 1 month and 3 month) rolling tracking errors in chart 6 below. We see that tracking error does vary over time and that it peaked during the April and May market volatility in 2005 (we also see this rise in volatility in charts 3 and 5). For most of the time, however, the tracking error has remained within a range of 20-40bp, though it has ticked up recently.

Adding iTraxx Subordinated Financials to the mix
We now try to reduce tracking error by mixing 5y iTraxx Europe with 5y and 10y iTraxx Subordinated Financials. At the start of each iTraxx series we choose weightings (by nominal value) for the 5y and 10y iTraxx Subordinated Financials such that the mix of the two matches the then current weight and modified duration of subordinated financials in the iBoxx EUR Corporates Overall (table 2 below). We preserve these weights for the entire iTraxx series.

In table 3 below we calculate the excess return and daily and weekly tracking error. We see that adding 5y and 10y iTraxx Subordinated Financials reduces the daily tracking error by 1.6bp and the weekly tracking error by 4.1bp (using traded levels in both cases). It may therefore be worth using iTraxx Subordinated Financials, but in the end it is probably quicker and simpler to just use 5y iTraxx Europe.


Where does the tracking error come from?
We illustrate the many differences between the iBoxx EUR Corporates Overall and the iTraxx Europe in table 4 below. It is not obvious a priori that they have much in common. In particular their constituents and the weights of those constituents are quite different and it is perhaps surprising that our synthetic replica tracks the bond index as well as it does, though they both offer diversified exposures to the EUR credit market.

We chart the spread of the iBoxx EUR Corporates Overall versus the spread of the 5y iTraxx Europe in chart 7 below. We see that they largely track each other, though there has been a recent outperformance by CDS. In particular, during the volatility of April and May 2005, both widened despite the fact Ford and General Motors were constituents of the iBoxx EUR Corporates Overall until the end of May 2005, whereas they have never been constituents of the iTraxx Europe.

The biggest cause of tracking error between a portfolio and its benchmark is typically duration mismatch. By using interest rate swaps, and rebalancing these at the end of every month to capture the change in composition of the bond index, we largely eliminate this as a source of tracking error.

As discussed in the previous section, the skew between the intrinsic and traded values of the iTraxx Europe causes some of the tracking error. We illustrate the skew in chart 8 below. We note that the skew is range bound, because otherwise it could be arbitraged.

We now analyse the remaining tracking error. We have constructed a family of custom bond indices which approach the composition of iTraxx Europe in terms of names, weights and maturities, as shown in table 5 below.

We construct the bond replica of iTraxx as follows. For each name in the on-the-run iTraxx Europe, we pick a bond from that issuer in the iBoxx EUR Corporates which is as close to the maturity of the on-the-run 5y iTraxx Europe as possible, excluding subordinated debt. We weight the bonds equally by nominal value, and we rebalance the bond replica at the end of every month. We note that we cannot find bonds corresponding to every iTraxx name - for example, as of July 2006, we can only find bonds corresponding to 92 of the 125 names.

We now apply our replication methodology to each of these custom indices using interest rate swaps plus 5y iTraxx Europe traded. We note that each custom index will have its own synthetic replica, since our methodology tries to match the custom index as closely as possible. We illustrate the excess return and daily and weekly tracking error of each of these synthetic replicas in chart 9 below.

We see that, very surprisingly, changing the composition of the bond index in terms of names, weights and maturities has almost no impact on tracking error (though the excess return of the bond replica of iTraxx is almost zero). What this means it that the mismatch in names, weights and maturities between the iBoxx EUR Corporates and iTraxx Europe introduces almost no tracking error, and the vast majority of tracking error is due to the basis between CDS and bonds.

Finally we show the spread of the bond replica of iTraxx over the past two years versus the spread of the 5y iTraxx Europe traded in chart 10 below.

Methodology
We summarise our replication methodology below. For more details, please refer to the aforementioned October 2005 publication or contact your usual ABN AMRO representative.
- We start by placing an initial amount of cash on deposit, earning a floating rate of 6 month EURIBOR.
- At every month end, we calculate the weight and modified duration of the 1-3y, 3-5y, 5-7y, 7-10y, 10-15y and 15y+ maturity buckets of the bond index. For each maturity bucket, we enter into two interest swaps on either side of the maturity bucket (except for the 15y+ bucket where we enter into a 15y and a 30y interest rate swap) where we pay EURIBOR and receive fixed such that the combined weight and modified duration of the two fixed legs matches that of the maturity bucket, and in addition the total notional of the resulting portfolio of interest rate swaps equals that of the cash deposit.
- Next, we sell protection on the most recent series of iTraxx 5y Europe with a size of notional equal to the notional of the cash deposit. This protection is unfunded and no notional value is paid upfront. A subtlety is this: the iTraxx 5y Europe actually pays a fixed coupon to the protection seller. As of Series 5, the coupon is 40bp. Because this is not necessarily a fair coupon, the protection buyer pays or receives an amount upfront. The spread quoted in the market is the coupon which would result in a net present value of zero. Thus if the quoted spread is above 40bp, the protection buyer makes an upfront payment to the protection seller to compensate for the fact that the coupon of 40bp is too low, whereas if the quoted spread is below 40bp, the protection buyer receives an upfront payment from the protection seller to compensate for the fact that the coupon of 40bp is too high. Therefore if we receive an upfront payment, we add this to our deposit, and if we have to make an upfront payment, we deduct this from our deposit.
- Thus we end up with a portfolio consisting of a cash deposit, 1y, 3y, 5y, 7y, 10y, 15y and 30y interest rate swaps and exposure to 5y iTraxx Europe. The mark to market of this portfolio will change on a daily basis as the net present value of iTraxx Europe changes, the fixed legs of the interest rate swaps roll down the swap curve, and the swap curve moves.
- At every month end, we rebalance the portfolio to capture changes in the composition of the bond index. We do this by selling the existing portfolio at its current mark-to-market to give us cash, and using this cash to construct a new synthetic portfolio as described above. The new portfolio replaces the off the run interest rate swaps of the old portfolio with on the run interest rate swaps, with weights adjusted to reflect the new interest rate exposure of the iBoxx index. If necessary we also replace the off-the-run 5y iTraxx Europe with the now on-the-run 5y iTraxx Europe. (The total notional of the portfolio will typically change too.)
- Finally, we hold iTraxx coupons as cash, earning no interest, until the next month end rebalancing.
- If we use both 5yr and 10yr iTraxx Europe in the synthetic portfolio, then at every month end the sum of the notionals must equal that of the deposit, and the weighted DV01 of the two maturities must match the modified duration of the bond index.


We note that we have slightly modified the replication method since the last publication. We now only roll our iTraxx exposure into the latest series at month-end when we rebalance the interest rate swaps, and not on the iTraxx roll date which occurs a few days earlier. This fractionally reduces the tracking error and simplifies the replication process.
