(1)
The amortized cost for fixed maturity securities and mortgage loans represents original cost reduced by repayments, write-downs from other-than-temporary declines in fair value, amortization of premiums, and/or accretion of discounts.

(2)
Derivatives are carried at fair value.

(3)
The difference between amortized cost and carrying value primarily results from changes in the partnership owner's equity since acquisition.
