The discount rate assumption was determined for the pension and postretirement benefit plans independently.
At year-end 2011, the Company began using an approach that approximates the process of settlement of obligations tailored to the plans’ expected cash flows by matching the plans’ cash flows to the coupons and expected maturity values of individually selected bonds.
The yield curve was developed for a universe containing the majority of U. S. -issued AA-graded corporate bonds, all of which were non callable (or callable with make-whole provisions).
Historically, for each plan, the discount rate was developed as the level equivalent rate that would produce the same present value as that using spot rates aligned with the projected benefit payments.
The expected long-term rate of return on plan assets is based on historical and projected rates of return, prior to administrative and investment management fees, for current and planned asset classes in the plans’ investment portfolios.
Assumed projected rates of return for each of the plans’ projected asset classes were selected after analyzing historical experience and future expectations of the returns and volatility of the various asset classes.
Based on the target asset allocation for each asset class, the overall expected rate of return for the portfolio was developed, adjusted for historical and expected experience of active portfolio management results compared to the benchmark returns and for the effect of expenses paid from plan assets.
The Company’s pension expense increases as the expected return on assets decreases.
In the determination of year end 2014 projected benefit plan obligations, the Company adopted a new table based on the Society of Actuaries RP 2014 mortality table including a generational BB-2D projection scale.
The adoption resulted in a significant increase to pension and other postretirement benefit plans’ projected benefit obligations.
Assumed health care cost trend rates have a significant effect on the amounts reported for the other postretirement benefit plans.
The health care cost trend rate is based on historical rates and expected market conditions.
A one-percentage-point change in assumed health care cost trend rates would have the following effects:

exchange memberships.
Also contributing to the increase in adjusted operating income was improved results from the segment’s asset management operations, principally reflecting higher performance fees and asset management fees in a joint venture, as well as more favorable sales and trading results from our global commodities group business.
Adjusted operating income in 2006 and 2005 includes $21 million and $24 million, respectively, of fee revenue from the Korean government under an agreement entered into in connection with the acquisition in 2004 of PISC, related to the provision of asset management and brokerage services, which agreement extends until February 27, 2009.2005 to 2004 Annual Comparison.
Adjusted operating income increased $29 million, from $77 million in 2004 to $106 million in 2005.
This increase is primarily a result of the acquisition of PISC, as the prior year reflects only ten months of results of the acquired business.
Also contributing to the increase in adjusted operating income was higher fee and commission income from our Korean asset management operations, which encompasses PISC, partially offset by a corresponding increase in operating expenses, including minority interest, during the current year.
Adjusted operating income in 2005 and 2004 includes $24 million and $20 million, respectively, of fee revenue from the Korean government under the agreement discussed above.
Revenues 2006 to 2005 Annual Comparison.

Revenues increased $41 million, from $446 million in 2004 to $487 million in 2005 primarily due to the results of PISC, as discussed above.
Expenses 2006 to 2005 Annual Comparison.
Expenses, as shown in the table above under “—Operating Results,” increased $66 million, from $381 million in 2005 to $447 million in 2006, primarily due to higher expenses corresponding with the higher level of revenues generated by our global commodities group business and our Korean asset management operations.2005 to 2004 Annual Comparison.
Expenses increased $12 million, from $369 million in 2004 to $381 million in 2005 primarily due to the results of PISC, as discussed above.
