[1] The expected long-term rates of return for pension and other postretirement benefits are based on management's projections using a best-estimate of expected returns, volatilities and correlations for each asset class. Each plan's specific current and expected asset allocations are also considered in developing a reasonable return assumption.

[2] Certain U.S. pension plans offered a limited-time program in 2013 during which terminated vested participants could elect to receive their accrued pension benefit as a one-time lump sum payment. The increase in gross benefits paid is primarily the result of $64 million of lump-sum cash payments made to terminated vested participants in 2013 in connection with these offerings.

[3] WPD is not subject to accounting for the effects of certain types of regulation as prescribed by GAAP. As a result, WPD does not record regulatory assets/liabilities.

[4] Certain LKE pension plans offered a limited-time program in 2013 during which terminated vested participants could elect to receive their accrued pension benefit as a one-time lump-sum payment. The increase in gross benefits paid is primarily the result of $21 million of lump-sum cash payments made to terminated vested participants in 2013 in connection with these offerings.

[5] LG&E's pension plan offered a limited-time program in 2013 during which terminated vested participants could elect to receive their accrued pension benefit as a one-time lump-sum payment. The increase in gross benefits paid is primarily the result of $7 million of lump-sum cash payments made to terminated vested participants in 2013 in connection with this offering.
