Duration is typically higher than the duration of an otherwise
identical, but unleveraged, bond portfolio, given that the duration of
liabilities is low relative to the duration of the assets they are
financing.

instrumentx(Price of underlying)/ (Price of option instrument)D of

Options can also be used by managers seeking to protect against a
decline in reinvestment rates resulting from a drop in interest rates.
The purchase of call options can be used in such situations. The sale of

covered call writing strategy does in protecting against a rise in
interest rates.

may be optimal; in the more likely case of uncertainty, strategy
combinations may produce the best expected risk/return trade-off.
incorrect duration calculations, inaccurate projected basis values, inaccurate yield beta estimates
