What are CPI bonds? CPI bonds overview n In the current market there is significant demand for Municipal CPI Bonds, especially from institutional investors looking for inflation hedging investments n Municipal CPI Bonds are floating rate bonds that pay a fixed spread over the trailing percentage change in the Consumer Price Index (CPI) n To date, issuers of Municipal CPI bonds have swapped them either to a fixed rate or BMA plus a fixed spread Issuer CPI + Spread n In the current market, the Issuer can take advantage of this market opportunity and save 10 or more basis points relative to traditional fixed rate bonds in selected maturities n Discussions with investors, as well as recent CPI Bond issues, indicate demand for “AAA” insured CPI bonds in the 8 to 20 year maturity range CPI Bonds What drives investor demand for municipal CPI bonds? n The prospects for inflation have generated increased investor interest in inflation-linked products F I N A N C I N G P R O D U C T S n Buyers of Municipal CPI bonds may be looking to express a view on inflation, fix a real rate of return and/or diversify their investment portfolio n Municipal CPI bonds offer a number of advantages relative to alternative investments n Commodities and stocks generally increase in value with rising inflation. However they do not provide direct or explicit inflation hedges, and are taxable n Tax-exempt money market funds are exempt but do not explicitly provide an inflation hedge n Treasury Inflation Protected Securities (TIPS) principal accretion structure generates “phantom” income and therefore have adverse tax implications I P E D 12

What are % of LIBOR bonds? Typical Bond Structure n Maturities range 10 -30 years and can be bullets or amortizing structures n Interest based upon 67% of 3 month LIBOR plus a fixed spread n Could be structured using a different reference rate, such as 1 month LIBOR or a constant maturity swap rate (i. e. , 5 or 10 year CMS rate) n Interest Paid Quarterly, with an Actual/Actual day count convention n Could be structured to pay with a different frequency or day count basis n Investors do not have a put to the Issuer n Bonds are insured or highly rated (AA- or above) n % of LIBOR + Spread May give Issuer a call option in 5 to 10 years n Issuer sells bonds through a public offering to investors % of LIBOR Bonds n Can be incorporated into multi-modal documents similar to VRDBs, if requested Why are % of LIBOR bonds so desirable to investors? F I N A N C I N G P R O D U C T S n Certain investors evaluate the % of LIBOR Bonds by comparing the % of LIBOR bonds swapped-to-fixed basis versus traditional fixed rate bonds n When compared to 20 year fixed rate bonds, the % of LIBOR bonds swapped-to-fixed would carry a lower all-in yield in the current market n Given the 5 year call on the bonds, a % of LIBOR bonds swapped-to-fixed would have a higher all-in yield in the current market n In addition, the current yield of the % of LIBOR bond is much higher than can be achieved in the current market on a long dated fixed rate bond due to the flatness of the yield curve n % of LIBOR bonds are a good diversification tool for this class of investor n If rates increase, fixed rate bonds will depreciate but the % of LIBOR bonds outperform, offering an attractive hedge I P E D 13

Energy risk management is a high priority n Utilities should work to institutionalize energy risk management as part of the utility’s overall risk management program n Natural gas and electricity risk can be bifurcated between physical and financial risks n Price and supply can be managed separately n Systematic price hedging can be advantageous n Structured transactions can offer significant value n Emissions markets continue to develop with much more active interest from Institutional Investors F I N A N C I N G P R O D U C T S An energy hedging program can help reduce price volatility, decreasing exposure to prices through periods of extreme price increases and reducing impact on a utility’s budget I P E D 15

Emissions markets The market n US SO 2 market is illiquid and challenged by highly inelastic supply/demand side n The nature of the market creates natural longs and shorts who are compelled to buy or sell with little sensitivity to price n The vast majority of S 02 allowances trade through the OTC Broker Market. Other sources of liquidity include: n Direct bilateral deals n OTC via Intercontinental Exchange (ICE) n NYMEX Futures (Clearport only) n Chicago Climate Exchange Futures n Prices are highly volatile and depend heavily on current supply and demand n Natural Shorts: n Large coal intensive generators F I N A N C I N G P R O D U C T S n Market makers, Suppliers: n Banks, Hedge Funds, Utilities, Municipalities I P E D 16

Emissions markets hedging transactions The market n Spot Market Purchases / Sales n Transactions are settled via electronic transfer between buyers/sellers EPA allowance accounts. n Physically Settled Options n Typically trade in larger volumes than the market for spot purchases/sales n Forward Market Purchases / Sales n Allows customers to lock in current allowances prices while delaying the settlement and associated cash flows until a future date n Customers generally execute these transactions only with highly rated counter parties. n Financially Settled Swaps & Options n Used when customer has exposure to price fluctuations in the emissions markets but does not have a need for the actual physical allowances. F I N A N C I N G P R O D U C T S n Vintage Swaps n Allows naturals to manage their allowance position across the different vintage years n Historically done as a like-kind exchange. Recently the ability of these transactions to achieve this tax benefit has been disputed. n Emission Lending Arrangements n Natural longs can earn a small rate of interest on idle allowances in their EPA accounts or borrow allowances to meet compliance obligation.
