Options Not Fully Pricing in 2006 Hurricane Risks for P&C Stocks

• P&C insurers experienced higher implied and realized volatility in response to the 2005 hurricane season.

• Since several independent weather forecasters are predicting another active hurricane season this year, we believe stocks within this industry could experience higher volatility, which the options market has yet to fully price in, in our opinion.

• Since medium-term implied volatility in the P&C space continues to be low relative to the market, and has generally been on a declining trend for much of this year, we recommend purchasing at-the-money straddles on insurers with exposure to hurricanes, such as MRH, RE, ALL, ACE, and CB.

Equity Derivatives Strategy | Options Not Fully Pricing in 2006 Hurricane Risks for P&C Stocks

May 22, 2006 2

P&C Insurance Volatility

Hurricanes represent risk to book value to P&C insurers and reinsurers. Recent forecasts for 2006 indicate expectations for another active hurricane season. We believe concern over losses from an active 2006 hurricane season could cause P&C insurance stocks to pull back, in the short-term. Alternatively, if hurricane losses in 2006 are not severe, P&C insurance stocks could rally, based on larger than expected preservation of book value.

Insurers we cover with exposure relative to book value from Atlantic hurricanes in our view:

• Most exposure: RNR, PRE, RE, and MRH.

• Moderate exposure: ALL, ACGL, AHL, XL, and ACE.

• Least exposure: STA, PGR, SAFC, CB, and AIG.

The Case for Higher Realized Volatility

We compare 6-month implied volatility at the beginning of the hurricane season with the “ex-post 6-month realized volatility” (the volatility actually realized during the corresponding six month period, after the fact) at the end of these hurricane seasons to identify instances when it would have been profitable to be long gamma in 2004 and 2005 (Figure 1). While the lack of listed options having 6 month maturities for several of the P&C names prevents comparison across the universe, we find that P&C stocks with moderate to high exposure to hurricanes tended to have higher realized volatility over the six months of the hurricane season than what was originally implied at the beginning of the period.

Since the beginning of 2006, price-to-book multiples for P&C insurers have been under pressure, possibly a reflection of investor concern over potential hurricane losses this season (Figure 2). In the event there are fewer property losses this year, there is a possibility, however, of multiple expansion in these names. We believe this factor, coupled with the stocks’ relatively low implied volatility, implies that straddles purchased ahead of this year’s hurricane season could be a profitable strategy – as the stocks could have substantial moves in either direction. This could occur in the event of either an active hurricane season (negative for stocks) or one that causes significantly lower losses than expected (positive for stocks).

Investment Conclusion

We believe average implied volatility on P&C insurers is not pricing in hurricane risk sufficiently, providing an attractive opportunity for investors to purchase at-the-money straddles. While option liquidity in this space remains a constraint, MRH, RE, ALL, ACE, and CB are P&C stocks we identify as having relatively liquid options. While CB has limited exposure to hurricanes on aggregate, it could be affected if any hurricanes hit the Northeastern U.S., which are at “high risk” this year, according to Accuweather meteorologists. Since the impact (or lack of impact) of the 2006 hurricane season varies due to unique geographic exposures – and the magnitude and location of hurricane landfalls is uncertain – we recommend investors take a long volatility position on all of these stocks.

For instance, MRH Oct 15 straddles can be purchased for $3.40 and finish in the money if the stock closes above $18.40 or below $11.60. RE Oct 90 straddles were offered at $10.70 as of last night’s close and the position is profitable if the stock finishes above $100.70 or below $79.30 as of the October 20th expiration date (which follows the most active portion of the hurricane season).

The ALL Oct 55 straddles can be purchased for $5.75 and would be profitable if ALL closes above $60.75 or below $49.25 at expiration. Investors can also purchase ACE Nov 55 straddles for $7.20. These would finish in the money if the stock closes above $62.20 or below $47.80 on October 20.

In case of CB, the Nov 50 straddles could be purchased for $5.35 and would lose money only if CB remains range-bound between $44.65 and $55.35.

Figure 3 summarizes the strikes and break-even prices as of last night’s close. With the exception of ALL, we find that in 2005, straddles purchased at these prices would have broken even as the average absolute return for these stocks over the entire hurricane season was 21.5%.

Review of 2005 Hurricane Season

The hurricanes of 2005 caused about $50 billion to $80 billion in insured losses, according to catastrophe modelers (12%-19% of total U.S. industry surplus). Median losses to P&C insurers represented 13% of book value (Figure 4). Losses varied from 1% of book value to over 100% of book value.

Realized Volatility Relatively Low in ’04, High in ‘05 We use absolute one-day returns of insurance stocks to gauge the magnitude of the impact the 2005 hurricanes had on these companies’ shares. In addition, the average of the daily absolute returns over each month can be used as an estimate of the profitability of an options strategy whereby investors would have gone long volatility in insurance names by purchasing options on each stock, and delta-hedging their positions at the close of each day (long gamma). We find insurers did not experience exceptionally high volatility in response to the 2004 hurricane season (Figure 5), which was a rather active season – particularly for Florida – with four major hurricanes (Cat 3 or higher) making landfall (hurricanes Charley, Frances, Ivan, Jeanne). The only month with unusually high volatility was October, owing to the Spitzer investigation into insurance brokers. However, the 2005 hurricane season generated much higher realized volatility for insurance stocks having high exposure to hurricanes, given the significantly larger damage to insured properties in the Gulf of Mexico coastal regions (hurricanes Dennis, Katrina, Rita, Wilma).


May 22, 2006 5

Heightened Risk Expectations Post Katrina We use the change in short term implied volatility for options on P&C insurers as an index of the level of risk expectations priced in by the options market. The spread of the weighted average implied volatilities of P&C insurers over S&P 500 implied volatility is a measure of the incremental risk specific to stocks with exposure to hurricanes. In 2005, we find that implied volatility for P&C stocks relative to the market reached its trough at the end of August. However, following hurricane Katrina’s landfall, there was a re-pricing of risk expectations for P&C options across the board (Figure 6). In fact, implied volatility for insurers with the highest exposure to hurricanes began to trade at a premium relative to the implied volatility for insurers having a moderate exposure. We caveat that the information content of implied volatility for stocks with the highest exposure to hurricanes be taken with the proverbial pinch of salt, given the lack of liquidity in these options.

In recent months, the implied volatility spread for insurers with the highest risk exposure has been declining, which could indicate that the options market is not pricing in hurricane risk sufficiently. As the onset of the 2006 hurricane season approaches, with outlooks released (and increasing media attention or headline risks surfacing), there is likely to be elevated investor attention to this risk and, we believe, another re-pricing of implied volatility, even in the absence of an immediate change in realized vols.

Hurricane Forecasts for 2006

NOAA (National Oceanic and Atmospheric Administration) released its 2006 hurricane forecast yesterday (May 22), saying it expects the 2006 hurricane season to be more active than average, but less active than 2005. The NOAA forecasts 13-16 named storms (average=11) to form in the Atlantic basin during the six-month season, which officially begins on June 1. The NOAA expects 8-10 of these storms to become hurricanes (average=6), with 4-6 (average= 2) of them intense hurricanes (category 3 or higher).

NOAA expects an above average active hurricane season due to warmer ocean water combined with lower wind shear, weaker easterly trade winds, and a more favorable wind pattern in the mid-levels of the atmosphere are the factors that collectively will favor the development of storms in greater numbers and to greater intensity. The Colorado State University (CSU) team led by Dr. William Gray also expects the 2006 hurricane season to be more active than average, but less active than 2005. The NOAA and CSU forecasts are mostly in line. (Figure 7). NOAA does not predict the probability of hurricanes making landfall because this depends on short-term factors that can not be predicted. However, based on historical statistics, NOAA estimates 2-4 hurricanes could make landfall in the U.S in 2006. Notably, the NOAA and CSU tend to be conservative in their forecasts. Figure 8 shows the NOAA and CSU forecasts versus the actual number of hurricanes and major hurricanes from 2003-2005.

As a result of increased expected hurricane activity, many insurers as well as catastrophe modeling firms are recalibrating their catastrophe models to include assumptions for increased frequency and severity of hurricanes. RMS, a catastrophe modeling firm, expects that updates to its 2006 hurricane model could result in at least a 50% increase in Atlantic hurricane loss expectations following the devastating 2005 storm results. EQECAT, another catastrophe modeler, adjusted its catastrophe model increasing expected loss frequency in the U.S. from Atlantic hurricanes by 40%. EQECAT’s severity assumptions increased 25% for both a 1 in 50 year event and a 1 in 100 year event; however, adjustments to EQECAT’s assumptions varied by region (Figure 9). Both EQECAT and RMS expect at least another five years of increased hurricane activity.

Dr. William Gray (CSU) is considered one of the leading experts on patterns of hurricane activity. The Colorado State University team’s most recent hurricane forecast (April) expects the 2006 hurricane season to be more active than average, but less active than 2005. The team forecasts 17 named storms (average 9.6) to form in the Atlantic basin during the six-month season, which officially begins on June 1. The team expects nine of these storms to become hurricanes, with five of them intense hurricanes (category 3 or higher). The CSU team provided probabilities of at least one major storm (category 3 or higher) making landfall in a coastal region in 2006:

• U.S. coastline: 81% (average for last century is 52%);

• U.S. east coast and Florida: 64% (average for last century is 31%);

• U.S. Gulf coast from Florida panhandle: 47% (average for last century is 30%); and

• Caribbean: above average risk.

Guide to Lehman Brothers Equity Research Rating System

Our coverage analysts use a relative rating system in which they rate stocks as 1-Overweight, 2- Equal weight or 3-Underweight (see definitions below) relative to other companies covered by the analyst or a team of analysts that are deemed to be in the same industry sector (“the sector coverage universe”). To see a list of companies that comprise a particular sector coverage universe, please go to www.lehman.com/disclosures.

In addition to the stock rating, we provide sector views which rate the outlook for the sector coverage universe as 1-Positive, 2-Neutral or 3-Negative (see definitions below). A rating system using terms such as buy, hold and sell is not the equivalent of our rating system. Investors should carefully read the entire research report including the definitions of all ratings and not infer its contents from ratings alone.

Stock Rating

1-Overweight - The stock is expected to outperform the unweighted expected total return of the sector coverage universe over a 12-month investment horizon.

2-Equal weight - The stock is expected to perform in line with the unweighted expected total return of the sector coverage universe over a 12-month investment horizon.

3-Underweight - The stock is expected to underperform the unweighted expected total return of the sector coverage universe over a 12-month investment horizon.

RS-Rating Suspended - The rating and target price have been suspended temporarily to comply with applicable regulations and/or firm policies in certain circumstances including when Lehman Brothers is acting in an advisory capacity on a merger or strategic transaction involving the company.Sector View

1-Positive - sector coverage universe fundamentals are improving.

2-Neutral - sector coverage universe fundamentals are steady, neither improving nor deteriorating.

3-Negative - sector coverage universe fundamentals are deteriorating.
