Pension and Postretirement Plans [Text Block]

Pension and Postretirement Plans

Savings Plans

The Company sponsors several defined contribution plans covering substantially all employees. The Company's contributions to the plans are based on matching a portion of the employee contributions. Both employer and employee contributions are invested in various investment funds at the direction of the employee. Employer contributions to the defined contribution plans were $6.9 million, $6.4 million, and $4.8 million in 2012, 2011, and 2010, respectively.

Pension and Postretirement Plans

The Company sponsors three noncontributory defined benefit pension plans: one for eligible management employees, one for non-management employees, and one supplemental, nonqualified, unfunded plan for certain former senior executives. The management pension plan is a cash balance plan in which the pension benefit is determined by a combination of compensation-based credits and annual guaranteed interest credits. The non-management pension plan is also a cash balance plan in which the combination of service and job-classification-based credits and annual interest credits determine the pension benefit. Benefits for the supplemental plan are based on eligible pay, adjusted for age and service upon retirement. We fund both the management and non-management plans in an irrevocable trust through contributions, which are determined using the traditional unit credit cost method. We also use the traditional unit credit cost method for determining pension cost for financial reporting purposes. Effective January 1, 2012, future pension service credits were eliminated for certain non-management employees which resulted in a remeasurement of the projected benefit obligations for this plan. In 2011, a curtailment loss of $4.2 million was recognized upon remeasurement.

The Company also provides healthcare and group life insurance benefits for eligible retirees. We fund healthcare benefits and other group life insurance benefits using Voluntary Employee Benefit Association ("VEBA") trusts. It is our practice to fund amounts as deemed appropriate from time to time. Contributions are subject to Internal Revenue Service ("IRS") limitations developed using the traditional unit credit cost method. The actuarial expense calculation for our postretirement health plan is based on numerous assumptions, estimates, and judgments including healthcare cost trend rates and cost sharing with retirees. Retiree healthcare benefits are being phased out for both management and certain retirees.

Components of Net Periodic Cost

The following information relates to noncontributory defined benefit pension plans, postretirement healthcare plans, and life insurance benefit plans. Approximately 11% in 2012, 7% in 2011, and 8% in 2010 of these costs were capitalized to property, plant and equipment related to network construction in the Wireline segment. Pension and postretirement benefit costs for these plans were comprised of:

	Pension Benefits									Postretirement and Other Benefits
(dollars in millions)	2012			2011			2010			2012			2011			2010
Service cost	$	2.6		$	5.1		$	5.2		$	0.5		$	0.3		$	0.2
Interest cost on projected benefit obligation	21.3			24.8			26.8			5.6			7.1			8.0
Expected return on plan assets	(26.1		)	(29.3		)	(30.3		)	—			—			—
Amortization of:
Prior service cost (benefit)	0.1			0.3			0.5			(13.2		)	(13.2		)	(13.1		)
Actuarial loss	19.4			14.3			9.3			6.8			6.5			5.2
Curtailment loss	—			4.2			—			—			—			—
Pension/postretirement costs	$	17.3		$	19.4		$	11.5		$	(0.3	)	$	0.7		$	0.3

The following are the weighted-average assumptions used in measuring the net periodic cost of the pension and postretirement benefits:

	Pension Benefits						Postretirement and Other Benefits
	2012		2011		2010		2012		2011		2010
Discount rate	3.90	%	4.90	%	5.50	%	3.60	%	4.50	%	5.10	%
Expected long-term rate of return	7.75	%	8.25	%	8.25	%	0	%	0	%	0	%
Future compensation growth rate	3.00	%	3.00	%	3.00	%	—		—		—

The expected long-term rate of return on plan assets, developed using the building block approach, is based on the mix of investments held directly by the plans and the current view of expected future returns, which is influenced by historical averages. Changes in actual asset return experience and discount rate assumptions can impact the Company’s operating results, financial position and cash flows.

Benefit Obligation and Funded Status

Changes in the plans' benefit obligations and funded status are as follows:

							Postretirement and Other Benefits
	Pension Benefits
(dollars in millions)	2012			2011			2012			2011
Change in benefit obligation:

Fair value of plan assets at December 31,	343.8			312.5			11.7			12.1
Unfunded status	$	(241.1	)	$	(256.7	)	$	(140.7	)	$	(152.8	)

The following are the weighted-average assumptions used in accounting for and measuring the projected benefit obligations:

	Pension Benefits				Postretirement and Other Benefits
	December 31,				December 31,
	2012		2011		2012		2011
Discount rate	3.30	%	3.90	%	3.10	%	3.60	%
Expected long-term rate of return	7.75	%	7.75	%	0	%	0	%
Future compensation growth rate	3.00	%	3.00	%	—		—

The assumed healthcare cost trend rate used to measure the postretirement health benefit obligation is shown below:

	December 31,
	2012		2011
Healthcare cost trend	6.5	%	8.0	%
Rate to which the cost trend is assumed to decline (ultimate trend rate)	4.5	%	4.5	%
Year the rates reach the ultimate trend rate	2016		2019

A one-percentage point change in assumed healthcare cost trend rates would have the following effect on the postretirement benefit costs and obligation:

(dollars in millions)	1% Increase		1% Decrease
Service and interest costs for 2012	$	0.2	$	(0.2	)
Postretirement benefit obligation at December 31, 2012	5.4		(4.8		)

The projected benefit obligation is recognized in the Consolidated Balance Sheets as follows:

	Pension Benefits				Postretirement and Other Benefits
	December 31,				December 31,
(dollars in millions)	2012		2011		2012		2011
Accrued payroll and benefits (current liability)	$	1.7	$	1.7	$	21.4	$	21.5
Pension and postretirement benefit obligations (noncurrent liability)	239.4		255.0		119.3		131.3
Total	$	241.1	$	256.7	$	140.7	$	152.8

Plan Assets, Investment Policies and Strategies

The primary investment objective for the trusts holding the assets of the pension and postretirement plans is preservation of capital with a reasonable amount of long-term growth and income without undue exposure to risk. This is provided by a balanced strategy using fixed income and equity securities. The target allocations for the pension plan assets are 61% equity securities, 33% investment grade fixed income securities and 6% in pooled real estate funds. Equity securities are primarily held in the form of passively managed funds that seek to track the performance of a benchmark index. Equity securities include investments in growth and value common stocks of companies located in the United States, which represents approximately 75% of the equity securities held by the pension plans at December 31, 2012 as well as stock of international companies located in both developed and emerging markets around the world. Fixed income securities primarily include holdings of funds, which generally invest in a variety of intermediate and long-term investment grade corporate bonds from diversified industries. The postretirement plan assets are currently invested in a group insurance contract.

The fair values of the pension and postretirement plan assets at December 31, 2012 and 2011 by asset category are as follows:

(dollars in millions)	December 31, 2012		Quoted Prices in active markets Level 1		Significant observable inputs Level 2		Significant unobservable inputs Level 3
Mutual funds
U.S. equity index funds	$	163.3	$	163.3	$	—	$	—

Total	$	355.5	$	316.0	$	—	$	39.5

(dollars in millions)	December 31, 2011		Quoted Prices in active markets Level 1		Significant observable inputs Level 2		Significant unobservable inputs Level 3
Mutual funds
U.S. equity index funds	$	150.6	$	150.6	$	—	$	—

Group insurance contract	12.1		—		—		12.1
Total	$	324.6	$	286.7	$	0.3	$	37.6

The fair values of Level 1 investments are based on quoted prices in active markets. The fair values of Level 2 investments, which consist of funds that hold securities in active markets, are determined based on the net asset value as reported by the fund manager.

The Level 3 investments consist of real estate pooled funds and a group insurance contract. The real estate pooled funds are valued at the net asset values disclosed by the fund managers, which are based on estimated fair values of the real estate investments using independent appraisal. The group insurance contract is valued at contract value plus accrued interest, which approximates fair value.

The Level 3 investments had the following changes in 2012 and 2011:

	Pension						Postretirement and Other Benefits
(dollars in millions)	2012			2011			2012			2011
Balance, beginning of year	$	25.5		$	21.1		$	12.1		$	12.3
Realized gains, net	1.0			1.7			0.4			0.3
Unrealized gains, net	1.8			3.1			—			—
Purchases, sales, issuances and settlements, net	(0.5		)	(0.4		)	(0.8		)	(0.5		)
Balance, end of year	$	27.8		$	25.5		$	11.7		$	12.1

Contributions to our qualified pension plans were $23.9 million in 2012, $18.1 million in 2011, and $5.6 million in 2010. Contributions to our non-qualified pension plan were $2.0 million, $2.0 million, and $2.1 million for 2012, 2011, and 2010, respectively.

Based on current assumptions, management believes it will make contributions of $41.6 million to the qualified pension plan in 2013. Contributions to non-qualified pension plans in 2013 are expected to be approximately $2.0 million. Management expects to make cash payments of approximately $20.5 million related to its postretirement health plans in 2013.

Estimated Future Benefit Payments

The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid over the next ten years:

(dollars in millions)	Pension Benefits		Postretirement and Other Benefits		Medicare Subsidy Receipts
