PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

2. PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Pension Plans

Laclede Gas has non-contributory, defined benefit, trusteed forms of pension plans covering substantially all employees. Plan assets consist primarily of corporate and U.S. government obligations and equity market exposure achieved through derivative instruments.

Pension costs for the quarters ended December 31, 2011 and 2010 were $4.2 million and $1.6 million, respectively, including amounts charged to construction.

The net periodic pension costs include the following components:

	Three Months Ended
	December 31,
(Thousands)	2011			2010
Service cost – benefits earned during the period	$	2,312		$	2,388
Interest cost on projected benefit obligation		4,871			4,705
Expected return on plan assets		(4,899	)		(4,712	)
Amortization of prior service cost		148			160
Amortization of actuarial loss		2,277			2,557
Sub-total		4,709			5,098
Regulatory adjustment		(483	)		(3,533	)
Net pension cost	$	4,226		$	1,565

Pursuant to the provisions of the Laclede Gas pension plans, pension obligations may be satisfied by lump-sum cash payments. Pursuant to a Missouri Public Service Commission (MoPSC or Commission) Order, lump-sum payments are recognized as settlements (which can result in gains or losses) only if the total of such payments exceeds 100% of the sum of service and interest costs. No lump-sum payments were recognized as settlements during the three months ended December 31, 2011 and December 31, 2010.

Pursuant to a MoPSC Order, the return on plan assets is based on the market-related value of plan assets implemented prospectively over a four-year period. Gains or losses not yet includible in pension cost are amortized only to the extent that such gain or loss exceeds 10% of the greater of the projected benefit obligation or the market-related value of plan assets. Such excess is amortized over the average remaining service life of active participants. The recovery in rates for the Utility’s qualified pension plans is based on an annual allowance of $4.8 million effective August 1, 2007 and $15.5 million effective January 1, 2011. The difference between these amounts and pension expense as calculated pursuant to the above and that otherwise would be included in the Statements of Income and Statements of Comprehensive Income is deferred as a regulatory asset or regulatory liability.

The funding policy of Laclede Gas is to contribute an amount not less than the minimum required by government funding standards, nor more than the maximum deductible amount for federal income tax purposes. Fiscal year 2012 contributions to the pension plans through December 31, 2011 were $17.6 million to the qualified trusts and approximately $0.1 million to the non-qualified plans. Contributions to the pension plans for the remaining nine months of fiscal year 2012 are anticipated to be at least $15.7 million to the qualified trusts and $6.6 million to the non-qualified plans.

Postretirement Benefits

Laclede Gas provides certain life insurance benefits at retirement. Medical insurance is available after early retirement until age 65. The transition obligation not yet includible in postretirement benefit cost is being amortized over 20 years. Postretirement benefit costs for the quarters ended December 31, 2011 and 2010 were $2.4 million and $1.9 million, respectively, including amounts charged to construction.

Net periodic postretirement benefit costs consisted of the following components:

	Three Months Ended
	December 31,
(Thousands)	2011			2010
Service cost – benefits earned during the period	$	2,015		$	1,919
Interest cost on accumulated
postretirement benefit obligation		1,380			1,211
Expected return on plan assets		(991	)		(911	)
Amortization of transition obligation		34			34
Amortization of prior service credit		(518	)		(582	)
Amortization of actuarial loss		1,065			1,110
Sub-total		2,985			2,781
Regulatory adjustment		(604	)		(871	)
Net postretirement benefit cost	$	2,381		$	1,910

Missouri state law provides for the recovery in rates of costs accrued pursuant to GAAP provided that such costs are funded through an independent, external funding mechanism. Laclede Gas established Voluntary Employees’ Beneficiary Association (VEBA) and Rabbi trusts as its external funding mechanisms. VEBA and Rabbi trusts’ assets consist primarily of money market securities and mutual funds invested in stocks and bonds.

Pursuant to a MoPSC Order, the return on plan assets is based on the market-related value of plan assets implemented prospectively over a four-year period. Gains and losses not yet includible in postretirement benefit cost are amortized only to the extent that such gain or loss exceeds 10% of the greater of the accumulated postretirement benefit obligation or the market-related value of plan assets. Such excess is amortized over the average remaining service life of active participants. The recovery in rates for the Utility’s postretirement benefit plans is based on an annual allowance of $7.6 million effective August 1, 2007 and $9.5 million effective January 1, 2011. The difference between these amounts and postretirement benefit cost based on the above and that otherwise would be included in the Statements of Income and Statements of Comprehensive Income is deferred as a regulatory asset or regulatory liability.

Laclede Gas’ funding policy is to contribute amounts to the trusts equal to the periodic benefit cost calculated pursuant to GAAP as recovered in rates. Fiscal year 2012 contributions to the postretirement plans through December 31, 2011 were approximately $0.1 million paid directly to participants from Laclede Gas’ funds. No contributions were made to the qualified trusts during the three months ended December 31, 2011. Contributions to the postretirement plans for the remaining nine months of fiscal year 2012 are anticipated to be $11.9 million to the qualified trusts and $0.3 million paid directly to participants from Laclede Gas’ funds.
