4 4 4 Structural Features of Callable Debt Maturity Date The latest and final possible date at which the security will be retired and principal will be redeemed at par. Lockout Period The amount of time for which a callable security cannot be called. For example, with a 3 noncall 1-year (“3nc1”) debt security, the security cannot be called for the first year. During this time, only coupon payments are made Type of Call Feature The type of call options embedded in a callable security Fannie Mae issues callable debt instruments with a variety of maturity dates along the yield curve. Fannie Mae issues callable debt with lockout periods of three months to as long as 10 years. Fannie Mae callable debt issues incorporate one of the following call features (after the lockout date): 1)American-style (continuous); 2)European-style (one-time); 3)Bermudan-style (only on a predetermined schedule of dates); 4)Canary-style (on a predetermined schedule of dates until designated called period ends).

12 How do we value and price callable debt? From our perspective, a five year maturity where we have the ability to call the note in one year with four years remaining. Hence, valuation components are two fold: * Our bullet cost of funds, one to five years. * Cost of the option that allows us to call a four year bond, one year forward. This is where it gets more complicated……

14 No market for options on Agency rates…..we utilize option pricing on swap rates as the two markets are highly correlated Source: Fannie Mae

15 Option terminology…. Black (Yield) vol: Market quoted implied volatility used to translate volatility to price Normal (BP) vol: Yield volatility multiplied by the forward rate. A measure that “normalizes” yield volatility with level of rates. 5nc1 Y Example…. Forward Rate…. As implied by current yield curve. Volatility quote is based on the strike set at the forward. Implied volatility sets the expected range of future rates. The higher the volatility assumption, the wider the expected range.

16 The Call Spread is dictated by the volatility assumption that is used to value the embedded option. Source: Fannie Mae

17 Calculating the par priced, callable bond coupon is an iterative process. The coupon (strike) where the value of the high coupon bullet is offset by the value of the option.

21 Bermudan pricing is the same process, the only difference is the use of a volatility surface instead of a single volatility assumption. Source: Fannie Mae The Bermudan volatility for a 5nc1Y is 32.1% compared to 36.4% for the 1X callable. However, the Bermudan coupon is still 6 BPs higher than the 1X bond.

23 Implied volatility levels fluctuate with rate levels though the relationship has reversed since Source: Barclays Capital

24 The volatility on strikes that are not ATM can vary. Below is 1x4 normal volatility with strikes +/- 200 bps. Source: Fannie Mae The difference between the ATM volatility and the one used for varying strikes is referred to as “skew”. Right now, high (low) strikes trade at a higher (lower) implied volatility compared to the ATM. AOAS is set to normal volatility.
