8. BENEFIT PLANS

 

For a discussion of investment strategy, investment limitations, target asset allocations and the classification of investments within the fair value hierarchy, see “Investments Held in Trust for Future Liabilities” and “Fair Value Measurements of Assets and Liabilities” sections of Note 1.

 

We sponsor a qualified pension plan and two unfunded nonqualified pension plans. Substantially all of our employees are covered by the qualified plan or both the qualified and a nonqualified pension plan. We sponsor OPEB plans to provide health and life insurance benefits for retired employees.

 

We recognize the funded status associated with our defined benefit pension and OPEB plans in the balance sheets. Disclosures about the plans are required by the “Compensation – Retirement Benefits” accounting guidance. We recognize an asset for a plan's overfunded status or a liability for a plan's underfunded status, and recognize, as a component of other comprehensive income, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. We record a regulatory asset instead of other comprehensive income for qualifying benefit costs of our regulated operations that for ratemaking purposes are deferred for future recovery. The cumulative funded status adjustment is equal to the remaining unrecognized deferrals for unamortized actuarial losses or gains, prior service costs and transition obligations, such that remaining deferred costs result in an AOCI equity reduction or regulatory asset and deferred gains result in an AOCI equity addition or regulatory liability.

Actuarial Assumptions for Benefit Obligations

 

The weighted-average assumptions as of December 31 of each year used in the measurement of our benefit obligations are shown in the following table:

 

      Other Postretirement
   Pension Plans  Benefit Plans
 Assumptions 2013  2012  2013 2012
 Discount Rate  4.70%   3.95%   4.70%  3.95%
 Rate of Compensation Increase  4.85%(a)  4.95%(a) NA NA

(a)       Rates are for base pay only. In addition, an amount is added to reflect target incentive compensation for exempt employees and overtime and incentive pay for nonexempt employees.

NA       Not applicable.

 

We use a duration-based method to determine the discount rate for our plans. A hypothetical portfolio of high quality corporate bonds is constructed with cash flows matching the benefit plan liability. The composite yield on the hypothetical bond portfolio is used as the discount rate for the plan.

 

For 2013, the rate of compensation increase assumed varies with the age of the employee, ranging from 3.5% per year to 11.5% per year, with an average increase of 4.85%.

Actuarial Assumptions for Net Periodic Benefit Costs

 

The weighted-average assumptions as of January 1 of each year used in the measurement of our benefit costs are shown in the following table:

 

      Other Postretirement
    Pension Plans Benefit Plans
   2013 2012 2011 2013 2012 2011
 Discount Rate  3.95%  4.55%  5.05%  3.95%  4.75%  5.25%
 Expected Return on Plan Assets  6.50%  7.25%  7.75%  7.00%  7.25%  7.50%
 Rate of Compensation Increase  4.95%  4.85%  4.85% NA NA NA
                    
 NA Not applicable.                  

The expected return on plan assets was determined by evaluating historical returns, the current investment climate (yield on fixed income securities and other recent investment market indicators), rate of inflation and current prospects for economic growth.

 

The health care trend rate assumptions as of January 1 of each year used for OPEB plans measurement purposes are shown below:

 

 Health Care Trend Rates 2013 2012
 Initial  6.75%  7.00%
 Ultimate  5.00%  5.00%
 Year Ultimate Reached 2020  2020 

Assumed health care cost trend rates have a significant effect on the amounts reported for the OPEB health care plans. A 1% change in assumed health care cost trend rates would have the following effects:

Significant Concentrations of Risk within Plan Assets

 

In addition to establishing the target asset allocation of plan assets, the investment policy also places restrictions on securities to limit significant concentrations within plan assets. The investment policy establishes guidelines that govern maximum market exposure, security restrictions, prohibited asset classes, prohibited types of transactions, minimum credit quality, average portfolio credit quality, portfolio duration and concentration limits. The guidelines were established to mitigate the risk of loss due to significant concentrations in any investment. We monitor the plans to control security diversification and ensure compliance with our investment policy. As of December 31, 2013, the assets were invested in compliance with all investment limits. See “Investments Held in Trust for Future Liabilities” section of Note 1 for limit details.

Benefit Plan Obligations, Plan Assets and Funded Status as of December 31, 2013 and 2012

 

The following tables provide a reconciliation of the changes in the plans' benefit obligations, fair value of plan assets and funded status as of December 31. The benefit obligation for the defined benefit pension and OPEB plans are the projected benefit obligation and the accumulated benefit obligation, respectively.

Determination of Pension Expense

 

We base our determination of pension expense or income on a market-related valuation of assets which reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses over a five-year period from the year in which they occur. Investment gains or losses for this purpose are the difference between the expected return calculated using the market-related value of assets and the actual return.

 

The accumulated benefit obligation for the pension plans is as follows:

 

   December 31,
 Accumulated Benefit Obligation 2013 2012
   (in millions)
 Qualified Pension Plan $ 4,638 $ 5,001
 Nonqualified Pension Plans   77   82
 Total $ 4,715 $ 5,083

For our underfunded pension plans that had an accumulated benefit obligation in excess of plan assets, the projected benefit obligation, accumulated benefit obligation and fair value of plan assets of these plans as of December 31, 2013 and 2012 were as follows:

   Underfunded Pension Plans
   December 31,
   2013 2012
   (in millions)
 Projected Benefit Obligation $ 4,841 $ 5,205
        
 Accumulated Benefit Obligation $ 4,715 $ 5,083
 Fair Value of Plan Assets   4,711   4,696
 Underfunded Accumulated Benefit Obligation $ (4) $ (387)

Estimated Future Benefit Payments and Contributions

 

We expect contributions and payments for the pension plans of $80 million and the OPEB plans of $6 million during 2014. For the pension plans, this amount includes the payment of unfunded nonqualified benefits plus contributions to the qualified trust fund of at least the minimum amount required by the Employee Retirement Income Security Act. For the qualified pension plan, we may also make additional discretionary contributions to maintain the funded status of the plan. For the OPEB plans, expected payments include the payment of unfunded benefits.

 

The table below reflects the total benefits expected to be paid from the plan or from our assets. The payments include the participants' contributions to the plan for their share of the cost. In November 2012, we announced changes to our retiree medical coverage. Effective for retirements after December 2012, our contribution to retiree medical coverage was capped reducing our exposure to future medical cost inflation. Effective for employees hired after December 2013, we will not provide retiree medical coverage. The impact of the changes is reflected in the Benefit Plan Obligation table as plan amendments. Future benefit payments are dependent on the number of employees retiring, whether the retiring employees elect to receive pension benefits as annuities or as lump sum distributions, future integration of the benefit plans with changes to Medicare and other legislation, future levels of interest rates and variances in actuarial results. The estimated payments for pension benefits and OPEB are as follows:

American Electric Power System Retirement Savings Plan

 

We sponsor the American Electric Power System Retirement Savings Plan, a defined contribution retirement savings plan for substantially all employees who are not members of the United Mine Workers of America (UMWA). It is a qualified plan offering participants an opportunity to contribute a portion of their pay with features under Section 401(k) of the Internal Revenue Code. The matching contributions to the plan are 100% of the first 1% of eligible employee contributions and 70% of the next 5% of contributions. The cost for matching contributions totaled $67 million in 2013, $66 million in 2012 and $64 million in 2011.

 

UMWA Benefits

 

We provide UMWA pension, health and welfare benefits for certain unionized mining employees, retirees and their survivors who meet eligibility requirements. UMWA trustees make final interpretive determinations with regard to all benefits. The pension benefits are administered by UMWA trustees and contributions are made to their trust funds. The health and welfare benefits are administered by us and benefits are paid from our general assets.

 

The UMWA pension benefits are administered through a multiemployer plan that is different from single-employer plans as an employer's contributions may be used to provide benefits to employees of other participating employers. Required contributions not made by any employer may result in other employers bearing the unfunded plan obligations, while a withdrawing employer may be subject to a withdrawal liability. UMWA pension benefits are provided through the United Mine Workers of America 1974 Pension Plan (Employer Identification Number: 52-1050282, Plan Number 002), which under the Pension Protection Act of 2006 (PPA) was in Seriously Endangered Status for the plan years ending June 30, 2013 and 2012, without utilization of extended amortization provisions. The Plan adopted a funding improvement plan in May 2012, as required under the PPA.

 

Contributions to the UMWA pension plan in 2013, 2012 and 2011 were made under a collective bargaining agreement that is scheduled to expire December 31, 2017. We contributed immaterial amounts in 2013, 2012 and 2011 that represent less than 5% of the total contributions in the plan's latest annual report for the years ended June 30, 2013, 2012 and 2011. The contributions we made did not include a surcharge. There are no minimum contributions for future years.

 

Based upon the plan to retrofit the Rockport Plant with dry sorbent injection technology to meet environmental emission control requirements, the timing of the closure of Cook Coal Terminal is expected to be in or after 2025. Due to the estimated closure date and the ability to estimate the amount of the withdrawal liability, we recorded a liability of $39 million during 2013 and a related regulatory asset of $30 million. The regulatory asset should be recovered in future billings for transloading services before the planned closure.

For a discussion of investment strategy, investment limitations, target asset allocations and the classification of investments within the fair value hierarchy, see “Investments Held in Trust for Future Liabilities” and “Fair Value Measurements of Assets and Liabilities” sections of Note 1.

 

The Registrant Subsidiaries participate in an AEP sponsored qualified pension plan and two unfunded nonqualified pension plans. Substantially all employees are covered by the qualified plan or both the qualified and a nonqualified pension plan. The Registrant Subsidiaries also participate in OPEB plans sponsored by AEP to provide health and life insurance benefits for retired employees.

 

Due to the Registrant Subsidiaries' participation in AEP's benefits plans, the assumptions used by the actuary and the accounting for the plans by each subsidiary are the same. This section details the assumptions that apply to all Registrant Subsidiaries and the rate of compensation increase for each subsidiary.

 

The Registrant Subsidiaries recognize the funded status associated with defined benefit pension and OPEB plans in their balance sheets. Disclosures about the plans are required by the “Compensation – Retirement Benefits” accounting guidance. The Registrant Subsidiaries recognize an asset for a plan's overfunded status or a liability for a plan's underfunded status, and recognize, as a component of other comprehensive income, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. The Registrant Subsidiaries record a regulatory asset instead of other comprehensive income for qualifying benefit costs of regulated operations that for ratemaking purposes are deferred for future recovery. The cumulative funded status adjustment is equal to the remaining unrecognized deferrals for unamortized actuarial losses or gains, prior service costs and transition obligations, such that remaining deferred costs result in an AOCI equity reduction or regulatory asset and deferred gains result in an AOCI equity addition or regulatory liability.

Actuarial Assumptions for Benefit Obligations

 

The weighted-average assumptions as of December 31 of each year used in the measurement of the Registrant Subsidiaries' benefit obligations are shown in the following tables:

     Other Postretirement
  Pension Plans  Benefit Plans
Assumption 2013 2012  2013 2012
Discount Rate  4.70%  3.95%   4.70%  3.95%

   Pension Plans
 Assumption - Rate of Compensation Increase (a) 2013 2012
 APCo  4.60%  4.70%
 I&M  4.90%  5.00%
 OPCo  5.00%  5.00%
 PSO  4.90%  4.90%
 SWEPCo  4.85%  4.75%

(a)       Rates are for base pay only. In addition, an amount is added to reflect target incentive compensation for exempt employees and overtime and incentive pay for nonexempt employees.

 

A duration-based method is used to determine the discount rate for the plans. A hypothetical portfolio of high quality corporate bonds is constructed with cash flows matching the benefit plan liability. The composite yield on the hypothetical bond portfolio is used as the discount rate for the plan. The discount rate is the same for each Registrant Subsidiary.

 

For 2013, the rate of compensation increase assumed varies with the age of the employee, ranging from 3.5% per year to 11.5% per year, with the average increase shown in the table above. The compensation increase rates reflect variations in each Registrant Subsidiary's population participating in the pension plan.

Actuarial Assumptions for Net Periodic Benefit Costs

 

The weighted-average assumptions as of January 1 of each year used in the measurement of each Registrant Subsidiary's benefit costs are shown in the following tables:

      Other Postretirement
    Pension Plans Benefit Plans
 Assumptions 2013 2012 2011 2013 2012 2011
 Discount Rate  3.95%  4.55%  5.05%  3.95%  4.75%  5.25%
 Expected Return on Plan Assets  6.50%  7.25%  7.75%  7.00%  7.25%  7.50%

   Pension Plans
 Assumption - Rate of Compensation Increase 2013 2012 2011
 APCo  4.70%  4.70%  4.65%
 I&M  5.00%  5.00%  4.90%
 OPCo  5.00%  5.00%  4.95%
 PSO  4.90%  4.90%  4.85%
 SWEPCo  4.75%  4.75%  4.70%

The expected return on plan assets was determined by evaluating historical returns, the current investment climate (yield on fixed income securities and other recent investment market indicators), rate of inflation and current prospects for economic growth. The expected return on plan assets is the same for each Registrant Subsidiary.

 

The health care trend rate assumptions as of January 1 of each year used for OPEB plans measurement purposes are shown below:

 Health Care Trend Rates 2013 2012
 Initial  6.75%  7.00%
 Ultimate  5.00%  5.00%
 Year Ultimate Reached 2020  2020 

Assumed health care cost trend rates have a significant effect on the amounts reported for the OPEB health care plans. A 1% change in assumed health care cost trend rates would have the following effects:

  1% Decrease   (14,552)   (5,603)   (5,760)   (2,617)   (2,927)

Significant Concentrations of Risk within Plan Assets

 

In addition to establishing the target asset allocation of plan assets, the investment policy also places restrictions on securities to limit significant concentrations within plan assets. The investment policy establishes guidelines that govern maximum market exposure, security restrictions, prohibited asset classes, prohibited types of transactions, minimum credit quality, average portfolio credit quality, portfolio duration and concentration limits. The guidelines were established to mitigate the risk of loss due to significant concentrations in any investment. Management monitors the plans to control security diversification and ensure compliance with the investment policy. As of December 31, 2013, the assets were invested in compliance with all investment limits. See “Investments Held in Trust for Future Liabilities” section of Note 1 for limit details.

Determination of Pension Expense

 

The determination of pension expense or income is based on a market-related valuation of assets which reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses over a five-year period from the year in which they occur. Investment gains or losses for this purpose are the difference between the expected return calculated using the market-related value of assets and the actual return.

 

The accumulated benefit obligation for the pension plans is as follows:

Estimated Future Benefit Payments and Contributions

 

The estimated pension benefit payments and contributions to the trust are at least the minimum amount required by the Employee Retirement Income Security Act plus payment of unfunded nonqualified benefits. For the qualified pension plan, additional discretionary contributions may also be made to maintain the funded status of the plan. For OPEB plans, expected payments include the payment of unfunded benefits. The following table provides the estimated contributions and payments by Registrant Subsidiary for 2014:

     Other Postretirement

 I&M   7,339   -
 OPCo   8,717   -
 PSO   3,530   -
 SWEPCo   1,296   -

The tables below reflect the total benefits expected to be paid from the plan or from the Registrant Subsidiary's assets. The payments include the participants' contributions to the plan for their share of the cost. In November 2012, changes to the retiree medical coverage were announced. Effective for retirements after December 2012, contributions to retiree medical coverage were capped reducing exposure to future medical cost inflation. Effective for employees hired after December 2013, retiree medical coverage will not be provided. The impact of the changes is reflected in the Benefit Plan Obligation tables as plan amendments. Future benefit payments are dependent on the number of employees retiring, whether the retiring employees elect to receive pension benefits as annuities or as lump sum distributions, future integration of the benefit plans with changes to Medicare and other legislation, future levels of interest rates and variances in actuarial results. The estimated payments for the pension benefits and OPEB are as follows:

American Electric Power System Retirement Savings Plan

 

The Registrant Subsidiaries participate in an AEP sponsored defined contribution retirement savings plan, the American Electric Power System Retirement Savings Plan, for substantially all employees who are not members of the United Mine Workers of America (UMWA). This qualified plan offers participants an opportunity to contribute a portion of their pay, includes features under Section 401(k) of the Internal Revenue Code and provides for company matching contributions. The matching contributions to the plan are 100% of the first 1% of eligible employee contributions and 70% of the next 5% of contributions.

 

The following table provides the cost for matching contributions to the retirement savings plans by Registrant Subsidiary for the years ended December 31, 2013, 2012 and 2011:

UMWA Benefits

 

APCo and I&M provide UMWA pension, health and welfare benefits for certain unionized mining employees, retirees and their survivors who meet eligibility requirements. UMWA trustees make final interpretive determinations with regard to all benefits. The pension benefits are administered by UMWA trustees and contributions are made to their trust funds. APCo and I&M administer the health and welfare benefits and pay them from their general assets.

 

The UMWA pension benefits are administered through a multiemployer plan that is different from single-employer plans as an employer's contributions may be used to provide benefits to employees of other participating employers. Required contributions not made by an employer may result in other employers bearing the unfunded plan obligations, while a withdrawing employer may be subject to a withdrawal liability. UMWA pension benefits are provided through the United Mine Workers of America 1974 Pension Plan (Employer Identification Number: 52-1050282, Plan Number 002), which under the Pension Protection Act of 2006 (PPA) was in Seriously Endangered Status for the plan years ending June 30, 2013 and 2012, without utilization of extended amortization provisions. The Plan adopted a funding improvement plan in May 2012, as required under the PPA.

 

Contributions to the UMWA pension plan in 2013, 2012 and 2011 were immaterial and represent less than 5% of the total contributions in the plan's latest annual report for the years ended June 30, 2013, 2012 and 2011. The contributions did not include a surcharge. There are no minimum contributions for future years.

7. BENEFIT PLANS

 

For a discussion of investment strategy, investment limitations, target asset allocations and the classification of investments within the fair value hierarchy, see “Investments Held in Trust for Future Liabilities” and “Fair Value Measurements of Assets and Liabilities” sections of Note 1.

 

The Registrant Subsidiaries participate in an AEP sponsored qualified pension plan and two unfunded nonqualified pension plans. Substantially all employees are covered by the qualified plan or both the qualified and a nonqualified pension plan. The Registrant Subsidiaries also participate in OPEB plans sponsored by AEP to provide health and life insurance benefits for retired employees.

 

Due to the Registrant Subsidiaries' participation in AEP's benefits plans, the assumptions used by the actuary and the accounting for the plans by each subsidiary are the same. This section details the assumptions that apply to all Registrant Subsidiaries and the rate of compensation increase for each subsidiary.

 

The Registrant Subsidiaries recognize the funded status associated with defined benefit pension and OPEB plans in their balance sheets. Disclosures about the plans are required by the “Compensation – Retirement Benefits” accounting guidance. The Registrant Subsidiaries recognize an asset for a plan's overfunded status or a liability for a plan's underfunded status, and recognize, as a component of other comprehensive income, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. The Registrant Subsidiaries record a regulatory asset instead of other comprehensive income for qualifying benefit costs of regulated operations that for ratemaking purposes are deferred for future recovery. The cumulative funded status adjustment is equal to the remaining unrecognized deferrals for unamortized actuarial losses or gains, prior service costs and transition obligations, such that remaining deferred costs result in an AOCI equity reduction or regulatory asset and deferred gains result in an AOCI equity addition or regulatory liability.

Actuarial Assumptions for Benefit Obligations

 

The weighted-average assumptions as of December 31 of each year used in the measurement of the Registrant Subsidiaries' benefit obligations are shown in the following tables:

     Other Postretirement
  Pension Plans  Benefit Plans
Assumption 2013 2012  2013 2012
Discount Rate  4.70%  3.95%   4.70%  3.95%

   Pension Plans
 Assumption - Rate of Compensation Increase (a) 2013 2012
 APCo  4.60%  4.70%
 I&M  4.90%  5.00%
 OPCo  5.00%  5.00%
 PSO  4.90%  4.90%
 SWEPCo  4.85%  4.75%

(a)       Rates are for base pay only. In addition, an amount is added to reflect target incentive compensation for exempt employees and overtime and incentive pay for nonexempt employees.

 

A duration-based method is used to determine the discount rate for the plans. A hypothetical portfolio of high quality corporate bonds is constructed with cash flows matching the benefit plan liability. The composite yield on the hypothetical bond portfolio is used as the discount rate for the plan. The discount rate is the same for each Registrant Subsidiary.

 

For 2013, the rate of compensation increase assumed varies with the age of the employee, ranging from 3.5% per year to 11.5% per year, with the average increase shown in the table above. The compensation increase rates reflect variations in each Registrant Subsidiary's population participating in the pension plan.

Actuarial Assumptions for Net Periodic Benefit Costs

 

The weighted-average assumptions as of January 1 of each year used in the measurement of each Registrant Subsidiary's benefit costs are shown in the following tables:

      Other Postretirement
    Pension Plans Benefit Plans
 Assumptions 2013 2012 2011 2013 2012 2011
 Discount Rate  3.95%  4.55%  5.05%  3.95%  4.75%  5.25%
 Expected Return on Plan Assets  6.50%  7.25%  7.75%  7.00%  7.25%  7.50%

   Pension Plans
 Assumption - Rate of Compensation Increase 2013 2012 2011
 APCo  4.70%  4.70%  4.65%
 I&M  5.00%  5.00%  4.90%
 OPCo  5.00%  5.00%  4.95%
 PSO  4.90%  4.90%  4.85%
 SWEPCo  4.75%  4.75%  4.70%

The expected return on plan assets was determined by evaluating historical returns, the current investment climate (yield on fixed income securities and other recent investment market indicators), rate of inflation and current prospects for economic growth. The expected return on plan assets is the same for each Registrant Subsidiary.

 

The health care trend rate assumptions as of January 1 of each year used for OPEB plans measurement purposes are shown below:

 Health Care Trend Rates 2013 2012
 Initial  6.75%  7.00%
 Ultimate  5.00%  5.00%
 Year Ultimate Reached 2020  2020 

Assumed health care cost trend rates have a significant effect on the amounts reported for the OPEB health care plans. A 1% change in assumed health care cost trend rates would have the following effects:

  1% Decrease   (14,552)   (5,603)   (5,760)   (2,617)   (2,927)

Significant Concentrations of Risk within Plan Assets

 

In addition to establishing the target asset allocation of plan assets, the investment policy also places restrictions on securities to limit significant concentrations within plan assets. The investment policy establishes guidelines that govern maximum market exposure, security restrictions, prohibited asset classes, prohibited types of transactions, minimum credit quality, average portfolio credit quality, portfolio duration and concentration limits. The guidelines were established to mitigate the risk of loss due to significant concentrations in any investment. Management monitors the plans to control security diversification and ensure compliance with the investment policy. As of December 31, 2013, the assets were invested in compliance with all investment limits. See “Investments Held in Trust for Future Liabilities” section of Note 1 for limit details.

Benefit Plan Obligations, Plan Assets and Funded Status as of December 31, 2013 and 2012

 

The following tables provide a reconciliation of the changes in the plans' benefit obligations, fair value of plan assets and funded status as of December 31.

Determination of Pension Expense

 

The determination of pension expense or income is based on a market-related valuation of assets which reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses over a five-year period from the year in which they occur. Investment gains or losses for this purpose are the difference between the expected return calculated using the market-related value of assets and the actual return.

 

The accumulated benefit obligation for the pension plans is as follows:

Estimated Future Benefit Payments and Contributions

 

The estimated pension benefit payments and contributions to the trust are at least the minimum amount required by the Employee Retirement Income Security Act plus payment of unfunded nonqualified benefits. For the qualified pension plan, additional discretionary contributions may also be made to maintain the funded status of the plan. For OPEB plans, expected payments include the payment of unfunded benefits. The following table provides the estimated contributions and payments by Registrant Subsidiary for 2014:

     Other Postretirement
 Company Pension Plans Benefit Plans
   (in thousands)
 APCo $ 12,231 $ 3,222
 I&M   7,339   -
 OPCo   8,717   -
 PSO   3,530   -
 SWEPCo   1,296   -

The tables below reflect the total benefits expected to be paid from the plan or from the Registrant Subsidiary's assets. The payments include the participants' contributions to the plan for their share of the cost. In November 2012, changes to the retiree medical coverage were announced. Effective for retirements after December 2012, contributions to retiree medical coverage were capped reducing exposure to future medical cost inflation. Effective for employees hired after December 2013, retiree medical coverage will not be provided. The impact of the changes is reflected in the Benefit Plan Obligation tables as plan amendments. Future benefit payments are dependent on the number of employees retiring, whether the retiring employees elect to receive pension benefits as annuities or as lump sum distributions, future integration of the benefit plans with changes to Medicare and other legislation, future levels of interest rates and variances in actuarial results. The estimated payments for the pension benefits and OPEB are as follows:

American Electric Power System Retirement Savings Plan

 

The Registrant Subsidiaries participate in an AEP sponsored defined contribution retirement savings plan, the American Electric Power System Retirement Savings Plan, for substantially all employees who are not members of the United Mine Workers of America (UMWA). This qualified plan offers participants an opportunity to contribute a portion of their pay, includes features under Section 401(k) of the Internal Revenue Code and provides for company matching contributions. The matching contributions to the plan are 100% of the first 1% of eligible employee contributions and 70% of the next 5% of contributions.

 

The following table provides the cost for matching contributions to the retirement savings plans by Registrant Subsidiary for the years ended December 31, 2013, 2012 and 2011:

    Years Ended December 31,

 OPCo   6,502   10,798   10,166
 PSO   3,784   3,732   3,626
 SWEPCo   4,970   4,890   4,438

UMWA Benefits

 

APCo and I&M provide UMWA pension, health and welfare benefits for certain unionized mining employees, retirees and their survivors who meet eligibility requirements. UMWA trustees make final interpretive determinations with regard to all benefits. The pension benefits are administered by UMWA trustees and contributions are made to their trust funds. APCo and I&M administer the health and welfare benefits and pay them from their general assets.

 

The UMWA pension benefits are administered through a multiemployer plan that is different from single-employer plans as an employer's contributions may be used to provide benefits to employees of other participating employers. Required contributions not made by an employer may result in other employers bearing the unfunded plan obligations, while a withdrawing employer may be subject to a withdrawal liability. UMWA pension benefits are provided through the United Mine Workers of America 1974 Pension Plan (Employer Identification Number: 52-1050282, Plan Number 002), which under the Pension Protection Act of 2006 (PPA) was in Seriously Endangered Status for the plan years ending June 30, 2013 and 2012, without utilization of extended amortization provisions. The Plan adopted a funding improvement plan in May 2012, as required under the PPA.

 

Contributions to the UMWA pension plan in 2013, 2012 and 2011 were immaterial and represent less than 5% of the total contributions in the plan's latest annual report for the years ended June 30, 2013, 2012 and 2011. The contributions did not include a surcharge. There are no minimum contributions for future years.

7. BENEFIT PLANS

 

For a discussion of investment strategy, investment limitations, target asset allocations and the classification of investments within the fair value hierarchy, see “Investments Held in Trust for Future Liabilities” and “Fair Value Measurements of Assets and Liabilities” sections of Note 1.

 

The Registrant Subsidiaries participate in an AEP sponsored qualified pension plan and two unfunded nonqualified pension plans. Substantially all employees are covered by the qualified plan or both the qualified and a nonqualified pension plan. The Registrant Subsidiaries also participate in OPEB plans sponsored by AEP to provide health and life insurance benefits for retired employees.

 

Due to the Registrant Subsidiaries' participation in AEP's benefits plans, the assumptions used by the actuary and the accounting for the plans by each subsidiary are the same. This section details the assumptions that apply to all Registrant Subsidiaries and the rate of compensation increase for each subsidiary.

 

The Registrant Subsidiaries recognize the funded status associated with defined benefit pension and OPEB plans in their balance sheets. Disclosures about the plans are required by the “Compensation – Retirement Benefits” accounting guidance. The Registrant Subsidiaries recognize an asset for a plan's overfunded status or a liability for a plan's underfunded status, and recognize, as a component of other comprehensive income, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. The Registrant Subsidiaries record a regulatory asset instead of other comprehensive income for qualifying benefit costs of regulated operations that for ratemaking purposes are deferred for future recovery. The cumulative funded status adjustment is equal to the remaining unrecognized deferrals for unamortized actuarial losses or gains, prior service costs and transition obligations, such that remaining deferred costs result in an AOCI equity reduction or regulatory asset and deferred gains result in an AOCI equity addition or regulatory liability.

Actuarial Assumptions for Benefit Obligations

 

The weighted-average assumptions as of December 31 of each year used in the measurement of the Registrant Subsidiaries' benefit obligations are shown in the following tables:

     Other Postretirement
  Pension Plans  Benefit Plans
Assumption 2013 2012  2013 2012
Discount Rate  4.70%  3.95%   4.70%  3.95%

   Pension Plans
 Assumption - Rate of Compensation Increase (a) 2013 2012
 APCo  4.60%  4.70%
 I&M  4.90%  5.00%
 OPCo  5.00%  5.00%
 PSO  4.90%  4.90%
 SWEPCo  4.85%  4.75%

(a)       Rates are for base pay only. In addition, an amount is added to reflect target incentive compensation for exempt employees and overtime and incentive pay for nonexempt employees.

 

A duration-based method is used to determine the discount rate for the plans. A hypothetical portfolio of high quality corporate bonds is constructed with cash flows matching the benefit plan liability. The composite yield on the hypothetical bond portfolio is used as the discount rate for the plan. The discount rate is the same for each Registrant Subsidiary.

 

For 2013, the rate of compensation increase assumed varies with the age of the employee, ranging from 3.5% per year to 11.5% per year, with the average increase shown in the table above. The compensation increase rates reflect variations in each Registrant Subsidiary's population participating in the pension plan.

Actuarial Assumptions for Net Periodic Benefit Costs

 

The weighted-average assumptions as of January 1 of each year used in the measurement of each Registrant Subsidiary's benefit costs are shown in the following tables:

      Other Postretirement
    Pension Plans Benefit Plans
 Assumptions 2013 2012 2011 2013 2012 2011
 Discount Rate  3.95%  4.55%  5.05%  3.95%  4.75%  5.25%
 Expected Return on Plan Assets  6.50%  7.25%  7.75%  7.00%  7.25%  7.50%

   Pension Plans
 Assumption - Rate of Compensation Increase 2013 2012 2011
 APCo  4.70%  4.70%  4.65%
 I&M  5.00%  5.00%  4.90%
 OPCo  5.00%  5.00%  4.95%
 PSO  4.90%  4.90%  4.85%
 SWEPCo  4.75%  4.75%  4.70%

The expected return on plan assets was determined by evaluating historical returns, the current investment climate (yield on fixed income securities and other recent investment market indicators), rate of inflation and current prospects for economic growth. The expected return on plan assets is the same for each Registrant Subsidiary.

 

The health care trend rate assumptions as of January 1 of each year used for OPEB plans measurement purposes are shown below:

 Health Care Trend Rates 2013 2012
 Initial  6.75%  7.00%
 Ultimate  5.00%  5.00%
 Year Ultimate Reached 2020  2020 

Assumed health care cost trend rates have a significant effect on the amounts reported for the OPEB health care plans. A 1% change in assumed health care cost trend rates would have the following effects:

  1% Decrease   (14,552)   (5,603)   (5,760)   (2,617)   (2,927)

Significant Concentrations of Risk within Plan Assets

 

In addition to establishing the target asset allocation of plan assets, the investment policy also places restrictions on securities to limit significant concentrations within plan assets. The investment policy establishes guidelines that govern maximum market exposure, security restrictions, prohibited asset classes, prohibited types of transactions, minimum credit quality, average portfolio credit quality, portfolio duration and concentration limits. The guidelines were established to mitigate the risk of loss due to significant concentrations in any investment. Management monitors the plans to control security diversification and ensure compliance with the investment policy. As of December 31, 2013, the assets were invested in compliance with all investment limits. See “Investments Held in Trust for Future Liabilities” section of Note 1 for limit details.

Benefit Plan Obligations, Plan Assets and Funded Status as of December 31, 2013 and 2012

 

The following tables provide a reconciliation of the changes in the plans' benefit obligations, fair value of plan assets and funded status as of December 31.

Determination of Pension Expense

 

The determination of pension expense or income is based on a market-related valuation of assets which reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses over a five-year period from the year in which they occur. Investment gains or losses for this purpose are the difference between the expected return calculated using the market-related value of assets and the actual return.

 

The accumulated benefit obligation for the pension plans is as follows:

Estimated Future Benefit Payments and Contributions

 

The estimated pension benefit payments and contributions to the trust are at least the minimum amount required by the Employee Retirement Income Security Act plus payment of unfunded nonqualified benefits. For the qualified pension plan, additional discretionary contributions may also be made to maintain the funded status of the plan. For OPEB plans, expected payments include the payment of unfunded benefits. The following table provides the estimated contributions and payments by Registrant Subsidiary for 2014:

     Other Postretirement
 Company Pension Plans Benefit Plans

 APCo $ 12,231 $ 3,222
 I&M   7,339   -
 OPCo   8,717   -
 PSO   3,530   -
 SWEPCo   1,296   -

The tables below reflect the total benefits expected to be paid from the plan or from the Registrant Subsidiary's assets. The payments include the participants' contributions to the plan for their share of the cost. In November 2012, changes to the retiree medical coverage were announced. Effective for retirements after December 2012, contributions to retiree medical coverage were capped reducing exposure to future medical cost inflation. Effective for employees hired after December 2013, retiree medical coverage will not be provided. The impact of the changes is reflected in the Benefit Plan Obligation tables as plan amendments. Future benefit payments are dependent on the number of employees retiring, whether the retiring employees elect to receive pension benefits as annuities or as lump sum distributions, future integration of the benefit plans with changes to Medicare and other legislation, future levels of interest rates and variances in actuarial results. The estimated payments for the pension benefits and OPEB are as follows:

American Electric Power System Retirement Savings Plan

 

The Registrant Subsidiaries participate in an AEP sponsored defined contribution retirement savings plan, the American Electric Power System Retirement Savings Plan, for substantially all employees who are not members of the United Mine Workers of America (UMWA). This qualified plan offers participants an opportunity to contribute a portion of their pay, includes features under Section 401(k) of the Internal Revenue Code and provides for company matching contributions. The matching contributions to the plan are 100% of the first 1% of eligible employee contributions and 70% of the next 5% of contributions.

 

The following table provides the cost for matching contributions to the retirement savings plans by Registrant Subsidiary for the years ended December 31, 2013, 2012 and 2011:

7. BENEFIT PLANS

 

For a discussion of investment strategy, investment limitations, target asset allocations and the classification of investments within the fair value hierarchy, see “Investments Held in Trust for Future Liabilities” and “Fair Value Measurements of Assets and Liabilities” sections of Note 1.

 

The Registrant Subsidiaries participate in an AEP sponsored qualified pension plan and two unfunded nonqualified pension plans. Substantially all employees are covered by the qualified plan or both the qualified and a nonqualified pension plan. The Registrant Subsidiaries also participate in OPEB plans sponsored by AEP to provide health and life insurance benefits for retired employees.

 

Due to the Registrant Subsidiaries' participation in AEP's benefits plans, the assumptions used by the actuary and the accounting for the plans by each subsidiary are the same. This section details the assumptions that apply to all Registrant Subsidiaries and the rate of compensation increase for each subsidiary.

 

The Registrant Subsidiaries recognize the funded status associated with defined benefit pension and OPEB plans in their balance sheets. Disclosures about the plans are required by the “Compensation – Retirement Benefits” accounting guidance. The Registrant Subsidiaries recognize an asset for a plan's overfunded status or a liability for a plan's underfunded status, and recognize, as a component of other comprehensive income, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. The Registrant Subsidiaries record a regulatory asset instead of other comprehensive income for qualifying benefit costs of regulated operations that for ratemaking purposes are deferred for future recovery. The cumulative funded status adjustment is equal to the remaining unrecognized deferrals for unamortized actuarial losses or gains, prior service costs and transition obligations, such that remaining deferred costs result in an AOCI equity reduction or regulatory asset and deferred gains result in an AOCI equity addition or regulatory liability.

Actuarial Assumptions for Benefit Obligations

 

The weighted-average assumptions as of December 31 of each year used in the measurement of the Registrant Subsidiaries' benefit obligations are shown in the following tables:

     Other Postretirement
  Pension Plans  Benefit Plans
Assumption 2013 2012  2013 2012
Discount Rate  4.70%  3.95%   4.70%  3.95%

   Pension Plans
 Assumption - Rate of Compensation Increase (a) 2013 2012
 APCo  4.60%  4.70%
 I&M  4.90%  5.00%
 OPCo  5.00%  5.00%
 PSO  4.90%  4.90%
 SWEPCo  4.85%  4.75%

(a)       Rates are for base pay only. In addition, an amount is added to reflect target incentive compensation for exempt employees and overtime and incentive pay for nonexempt employees.

 

A duration-based method is used to determine the discount rate for the plans. A hypothetical portfolio of high quality corporate bonds is constructed with cash flows matching the benefit plan liability. The composite yield on the hypothetical bond portfolio is used as the discount rate for the plan. The discount rate is the same for each Registrant Subsidiary.

 

For 2013, the rate of compensation increase assumed varies with the age of the employee, ranging from 3.5% per year to 11.5% per year, with the average increase shown in the table above. The compensation increase rates reflect variations in each Registrant Subsidiary's population participating in the pension plan.

Actuarial Assumptions for Net Periodic Benefit Costs

 

The weighted-average assumptions as of January 1 of each year used in the measurement of each Registrant Subsidiary's benefit costs are shown in the following tables:

      Other Postretirement
    Pension Plans Benefit Plans
 Assumptions 2013 2012 2011 2013 2012 2011
 Discount Rate  3.95%  4.55%  5.05%  3.95%  4.75%  5.25%
 Expected Return on Plan Assets  6.50%  7.25%  7.75%  7.00%  7.25%  7.50%

   Pension Plans
 Assumption - Rate of Compensation Increase 2013 2012 2011
 APCo  4.70%  4.70%  4.65%
 I&M  5.00%  5.00%  4.90%
 OPCo  5.00%  5.00%  4.95%
 PSO  4.90%  4.90%  4.85%
 SWEPCo  4.75%  4.75%  4.70%

The expected return on plan assets was determined by evaluating historical returns, the current investment climate (yield on fixed income securities and other recent investment market indicators), rate of inflation and current prospects for economic growth. The expected return on plan assets is the same for each Registrant Subsidiary.

 

The health care trend rate assumptions as of January 1 of each year used for OPEB plans measurement purposes are shown below:

 Health Care Trend Rates 2013 2012
 Initial  6.75%  7.00%
 Ultimate  5.00%  5.00%
 Year Ultimate Reached 2020  2020 

Assumed health care cost trend rates have a significant effect on the amounts reported for the OPEB health care plans. A 1% change in assumed health care cost trend rates would have the following effects:

Significant Concentrations of Risk within Plan Assets

 

In addition to establishing the target asset allocation of plan assets, the investment policy also places restrictions on securities to limit significant concentrations within plan assets. The investment policy establishes guidelines that govern maximum market exposure, security restrictions, prohibited asset classes, prohibited types of transactions, minimum credit quality, average portfolio credit quality, portfolio duration and concentration limits. The guidelines were established to mitigate the risk of loss due to significant concentrations in any investment. Management monitors the plans to control security diversification and ensure compliance with the investment policy. As of December 31, 2013, the assets were invested in compliance with all investment limits. See “Investments Held in Trust for Future Liabilities” section of Note 1 for limit details.

Determination of Pension Expense

 

The determination of pension expense or income is based on a market-related valuation of assets which reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses over a five-year period from the year in which they occur. Investment gains or losses for this purpose are the difference between the expected return calculated using the market-related value of assets and the actual return.

 

The accumulated benefit obligation for the pension plans is as follows:

Estimated Future Benefit Payments and Contributions

 

The estimated pension benefit payments and contributions to the trust are at least the minimum amount required by the Employee Retirement Income Security Act plus payment of unfunded nonqualified benefits. For the qualified pension plan, additional discretionary contributions may also be made to maintain the funded status of the plan. For OPEB plans, expected payments include the payment of unfunded benefits. The following table provides the estimated contributions and payments by Registrant Subsidiary for 2014:

     Other Postretirement
 Company Pension Plans Benefit Plans

 APCo $ 12,231 $ 3,222
 I&M   7,339   -
 OPCo   8,717   -
 PSO   3,530   -
 SWEPCo   1,296   -

The tables below reflect the total benefits expected to be paid from the plan or from the Registrant Subsidiary's assets. The payments include the participants' contributions to the plan for their share of the cost. In November 2012, changes to the retiree medical coverage were announced. Effective for retirements after December 2012, contributions to retiree medical coverage were capped reducing exposure to future medical cost inflation. Effective for employees hired after December 2013, retiree medical coverage will not be provided. The impact of the changes is reflected in the Benefit Plan Obligation tables as plan amendments. Future benefit payments are dependent on the number of employees retiring, whether the retiring employees elect to receive pension benefits as annuities or as lump sum distributions, future integration of the benefit plans with changes to Medicare and other legislation, future levels of interest rates and variances in actuarial results.

American Electric Power System Retirement Savings Plan

 

The Registrant Subsidiaries participate in an AEP sponsored defined contribution retirement savings plan, the American Electric Power System Retirement Savings Plan, for substantially all employees who are not members of the United Mine Workers of America (UMWA). This qualified plan offers participants an opportunity to contribute a portion of their pay, includes features under Section 401(k) of the Internal Revenue Code and provides for company matching contributions. The matching contributions to the plan are 100% of the first 1% of eligible employee contributions and 70% of the next 5% of contributions.

 

The following table provides the cost for matching contributions to the retirement savings plans by Registrant Subsidiary for the years ended December 31, 2013, 2012 and 2011:

7. BENEFIT PLANS

 

For a discussion of investment strategy, investment limitations, target asset allocations and the classification of investments within the fair value hierarchy, see “Investments Held in Trust for Future Liabilities” and “Fair Value Measurements of Assets and Liabilities” sections of Note 1.

 

The Registrant Subsidiaries participate in an AEP sponsored qualified pension plan and two unfunded nonqualified pension plans. Substantially all employees are covered by the qualified plan or both the qualified and a nonqualified pension plan. The Registrant Subsidiaries also participate in OPEB plans sponsored by AEP to provide health and life insurance benefits for retired employees.

 

Due to the Registrant Subsidiaries' participation in AEP's benefits plans, the assumptions used by the actuary and the accounting for the plans by each subsidiary are the same. This section details the assumptions that apply to all Registrant Subsidiaries and the rate of compensation increase for each subsidiary.

 

The Registrant Subsidiaries recognize the funded status associated with defined benefit pension and OPEB plans in their balance sheets. Disclosures about the plans are required by the “Compensation – Retirement Benefits” accounting guidance. The Registrant Subsidiaries recognize an asset for a plan's overfunded status or a liability for a plan's underfunded status, and recognize, as a component of other comprehensive income, the changes in the funded status of the plan that arise during the year that are not recognized as a component of net periodic benefit cost. The Registrant Subsidiaries record a regulatory asset instead of other comprehensive income for qualifying benefit costs of regulated operations that for ratemaking purposes are deferred for future recovery. The cumulative funded status adjustment is equal to the remaining unrecognized deferrals for unamortized actuarial losses or gains, prior service costs and transition obligations, such that remaining deferred costs result in an AOCI equity reduction or regulatory asset and deferred gains result in an AOCI equity addition or regulatory liability.

Actuarial Assumptions for Benefit Obligations

 

The weighted-average assumptions as of December 31 of each year used in the measurement of the Registrant Subsidiaries' benefit obligations are shown in the following tables:

     Other Postretirement
  Pension Plans  Benefit Plans
Assumption 2013 2012  2013 2012
Discount Rate  4.70%  3.95%   4.70%  3.95%

   Pension Plans
 Assumption - Rate of Compensation Increase (a) 2013 2012
 APCo  4.60%  4.70%
 I&M  4.90%  5.00%
 OPCo  5.00%  5.00%
 PSO  4.90%  4.90%
 SWEPCo  4.85%  4.75%

(a)       Rates are for base pay only. In addition, an amount is added to reflect target incentive compensation for exempt employees and overtime and incentive pay for nonexempt employees.

 

A duration-based method is used to determine the discount rate for the plans. A hypothetical portfolio of high quality corporate bonds is constructed with cash flows matching the benefit plan liability. The composite yield on the hypothetical bond portfolio is used as the discount rate for the plan. The discount rate is the same for each Registrant Subsidiary.

 

For 2013, the rate of compensation increase assumed varies with the age of the employee, ranging from 3.5% per year to 11.5% per year, with the average increase shown in the table above. The compensation increase rates reflect variations in each Registrant Subsidiary's population participating in the pension plan.

Actuarial Assumptions for Net Periodic Benefit Costs

 

The weighted-average assumptions as of January 1 of each year used in the measurement of each Registrant Subsidiary's benefit costs are shown in the following tables:

      Other Postretirement
    Pension Plans Benefit Plans
 Assumptions 2013 2012 2011 2013 2012 2011
 Discount Rate  3.95%  4.55%  5.05%  3.95%  4.75%  5.25%
 Expected Return on Plan Assets  6.50%  7.25%  7.75%  7.00%  7.25%  7.50%

   Pension Plans
 Assumption - Rate of Compensation Increase 2013 2012 2011
 APCo  4.70%  4.70%  4.65%
 I&M  5.00%  5.00%  4.90%
 OPCo  5.00%  5.00%  4.95%
 PSO  4.90%  4.90%  4.85%
 SWEPCo  4.75%  4.75%  4.70%

The expected return on plan assets was determined by evaluating historical returns, the current investment climate (yield on fixed income securities and other recent investment market indicators), rate of inflation and current prospects for economic growth. The expected return on plan assets is the same for each Registrant Subsidiary.

 

The health care trend rate assumptions as of January 1 of each year used for OPEB plans measurement purposes are shown below:

 Health Care Trend Rates 2013 2012
 Initial  6.75%  7.00%
 Ultimate  5.00%  5.00%
 Year Ultimate Reached 2020  2020 

Assumed health care cost trend rates have a significant effect on the amounts reported for the OPEB health care plans. A 1% change in assumed health care cost trend rates would have the following effects:

  1% Decrease   (14,552)   (5,603)   (5,760)   (2,617)   (2,927)

Significant Concentrations of Risk within Plan Assets

 

In addition to establishing the target asset allocation of plan assets, the investment policy also places restrictions on securities to limit significant concentrations within plan assets. The investment policy establishes guidelines that govern maximum market exposure, security restrictions, prohibited asset classes, prohibited types of transactions, minimum credit quality, average portfolio credit quality, portfolio duration and concentration limits. The guidelines were established to mitigate the risk of loss due to significant concentrations in any investment. Management monitors the plans to control security diversification and ensure compliance with the investment policy. As of December 31, 2013, the assets were invested in compliance with all investment limits. See “Investments Held in Trust for Future Liabilities” section of Note 1 for limit details.

Benefit Plan Obligations, Plan Assets and Funded Status as of December 31, 2013 and 2012

 

The following tables provide a reconciliation of the changes in the plans' benefit obligations, fair value of plan assets and funded status as of December 31.

Determination of Pension Expense

 

The determination of pension expense or income is based on a market-related valuation of assets which reduces year-to-year volatility. This market-related valuation recognizes investment gains or losses over a five-year period from the year in which they occur. Investment gains or losses for this purpose are the difference between the expected return calculated using the market-related value of assets and the actual return.

 

The accumulated benefit obligation for the pension plans is as follows:

Estimated Future Benefit Payments and Contributions

 

The estimated pension benefit payments and contributions to the trust are at least the minimum amount required by the Employee Retirement Income Security Act plus payment of unfunded nonqualified benefits. For the qualified pension plan, additional discretionary contributions may also be made to maintain the funded status of the plan. For OPEB plans, expected payments include the payment of unfunded benefits. The following table provides the estimated contributions and payments by Registrant Subsidiary for 2014:

     Other Postretirement
 Company Pension Plans Benefit Plans
   (in thousands)
 APCo $ 12,231 $ 3,222
 I&M   7,339   -
 OPCo   8,717   -
 PSO   3,530   -
 SWEPCo   1,296   -

The tables below reflect the total benefits expected to be paid from the plan or from the Registrant Subsidiary's assets. The payments include the participants' contributions to the plan for their share of the cost. In November 2012, changes to the retiree medical coverage were announced. Effective for retirements after December 2012, contributions to retiree medical coverage were capped reducing exposure to future medical cost inflation. Effective for employees hired after December 2013, retiree medical coverage will not be provided. The impact of the changes is reflected in the Benefit Plan Obligation tables as plan amendments. Future benefit payments are dependent on the number of employees retiring, whether the retiring employees elect to receive pension benefits as annuities or as lump sum distributions, future integration of the benefit plans with changes to Medicare and other legislation, future levels of interest rates and variances in actuarial results. The estimated payments for the pension benefits and OPEB are as follows:
