8. EMPLOYEE BENEFIT PLANS
Pension and Other Postretirement Benefit Plans
The Company sponsors a noncontributory defined benefit pension plan covering substantially all regular, full-time
employees. The Company’s policy has been to fund the plan to the extent permitted by applicable federal income tax regulations, as
determined by an independent actuary.
The Company’s pension plan provides benefits under a cash balance formula for employees hired before January 1, 2000
who elected that option and for all employees hired on or after January 1, 2000. Under the cash balance formula, benefits accumulate
as a result of compensation credits and interest credits. Employees hired before January 1, 2000 who elected to remain under the final
average pay formula earn benefits based on years of credited service and the employee’s average annual base earnings received during
the last three years of employment.
In addition to pension benefits, the Company provides certain unfunded postretirement health care and life insurance
benefits to certain active and retired employees. Retirees share in a portion of their medical care cost. The Company provides life
insurance benefits to retirees at no charge. The costs of postretirement benefits other than pensions are accrued during the years the
employees render the services necessary to be eligible for these benefits.

The accumulated benefit obligation for retirement benefits was $784.9 million at the end of 2011 and $766.0 million at the
end of 2010. The accumulated retirement benefit obligation differs from the projected retirement benefit obligation above in that it
reflects no assumptions about future compensation levels.
Significant assumptions used to determine the above benefit obligations are as follows:
2011 2010
Annual discount rate used to determine benefit obligation

Assumed annual rate of future salary increases for projected benefit
obligation 4.00% 4.00% 4.00% 4.00%
An 8.2% annual rate of increase in the per capita cost of covered health care benefits was assumed for 2012. The rate was
assumed to decrease gradually to 5.0% for 2020 and to remain at that level thereafter.
A one percent increase in the assumed health care cost trend rate would increase the postretirement benefit obligation at
December 31, 2011 by $1.7 million and at December 31, 2010 by $1.8 million. A one percent decrease in the assumed health care cost
trend rate would decrease the postretirement benefit obligation at December 31, 2011 by $1.5 million and at December 31, 2010 by
$1.6 million.
