EMPLOYEE BENEFIT PLANS AND EQUITY COMPENSATION PLAN

Pension and Other Postretirement Benefit Plans

The Company sponsors a noncontributory defined benefit pension plan covering substantially all regular, full-time employees hired before January 1, 2014. Benefits are no longer offered to employees hired or rehired after December 31, 2013, and pension benefits for existing participants will no longer accrue for services performed or compensation earned after December 31, 2023. The Company’s policy has been to fund the plan as 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 eligible employees hired subsequently. 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. Benefits under the cash balance formula and the final average pay formula will continue to accrue through December 31, 2023, after which date no benefits will be accrued except that participants under the cash balance formula will continue to earn interest credits.

In addition to pension benefits, the Company provides certain unfunded postretirement health care and life insurance benefits to certain active and retired employees. Retirees hired before January 1, 2011 share in a portion of their medical care cost. Employees hired after December 31, 2010 are responsible for the full cost of retiree medical benefits elected by them. 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.

Changes in Benefit Obligations

The measurement date used to determine pension and other postretirement benefit obligations is December 31. Data related to the changes in the projected benefit obligation for pension benefits and the accumulated benefit obligation for other postretirement benefits are presented below.

Curtailment	—			(25.5		)	—			—
Benefit obligation, December 31	$	919.5		$	823.0		$	268.2		$	238.0

The accumulated benefit obligation for pension benefits was $888.3 million at the end of 2014 and $796.4 million at the end of 2013. The accumulated pension benefit obligation differs from the projected pension 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:

	Pension Benefits				Other Postretirement Benefits
	2014		2013		2014		2013
Annual discount rate used to determine benefit obligation	4.20	%	5.03	%	4.30	%	5.19	%
Assumed annual rate of future salary increases for projected benefit obligation	3.00	%	3.00	%	3.00	%	3.75	%

A 7.0% annual rate of increase in the per capita cost of covered health care benefits was assumed for 2014. 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 by $1.1 million at December 31, 2014 and by $1.3 million at December 31, 2013. A one percent decrease in the assumed health care cost trend rate would decrease the postretirement benefit obligation by $1.0 million at December 31, 2014 and by $1.2 million at December 31, 2013.

In connection with the joint ownership of Summer Station, as of December 31, 2014 and 2013, the Company recorded within deferred debits $17.8 million and $14.1 million, respectively, attributable to Santee Cooper’s portion of shared pension costs. As of December 31, 2014 and 2013, the Company also recorded within deferred debits $15.1 million and $12.6 million, respectively, from Santee Cooper, representing its portion of the unfunded postretirement benefit obligation.

Fair value of plan assets, December 31	$	861.8		$	870.0

Investment Policies and Strategies

The assets of the pension plan are invested in accordance with the objectives of (1) fully funding the obligations of the pension plan, (2) overseeing the plan's investments in an asset-liability framework that considers the funding surplus (or deficit) between assets and liabilities, and overall risk associated with assets as compared to liabilities, and (3) maintaining sufficient liquidity to meet benefit payment obligations on a timely basis. The pension plan is closed to new entrants effective January 1, 2014, and benefit accruals will cease effective January 1, 2024. In addition, during 2013, the Company adopted a dynamic investment strategy for the management of the pension plan assets. The strategy will lead to a reduction in equities and an increase in long duration fixed income allocations over time with the intention of reducing volatility of funded status and pension costs in connection with the amendments to the plan.

The pension plan operates with several risk and control procedures, including ongoing reviews of liabilities, investment objectives, levels of diversification, investment managers and performance expectations. The total portfolio is constructed and maintained to provide prudent diversification with regard to the concentration of holdings in individual issues, corporations, or industries.

Transactions involving certain types of investments are prohibited. These include, except where utilized by a hedge fund manager, any form of private equity; commodities or commodity contracts (except for unleveraged stock or bond index futures and currency futures and options); ownership of real estate in any form other than publicly traded securities; short sales, warrants or margin transactions, or any leveraged investments; and natural resource properties. Investments made for the purpose of engaging in speculative trading are also prohibited.

The Company’s pension plan asset allocation at December 31, 2014 and 2013 and the target allocation for 2015 are as follows: 

	Percentage of Plan Assets
	Target Allocation		At December 31,
Asset Category	2015		2014		2013
Equity Securities	58	%	57	%	59	%
Fixed Income	33	%	34	%	32	%
Hedge Funds	9	%	9	%	9	%

For 2015, the expected long-term rate of return on assets will be 7.50%. In developing the expected long-term rate of return assumptions, management evaluates the pension plan’s historical cumulative actual returns over several periods, considers the expected active returns across various asset classes and assumes an asset allocation of 58% with equity managers, 33% with fixed income managers and 9% with hedge fund managers. Management regularly reviews such allocations and periodically rebalances the portfolio when considered appropriate. Additional rebalancing may occur subject to funded status improvements as part of the dynamic investment strategy adopted for 2013.

Fair Value Measurements

Assets held by the pension plan are measured at fair value as described below. Assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. At December 31, 2014 and 2013, fair value measurements, and the level within the fair value hierarchy in which the measurements fall, were as follows:

	Fair Value Measurements at Reporting Date Using

At December 31, 2014, assets with fair value measurements classified as Level 1 were insignificant. There were no transfers of fair value amounts into or out of Levels 1, 2 or 3 during 2014 or 2013.

The pension plan values common stock, preferred stock and certain mutual funds, where applicable, using unadjusted quoted prices from a national stock exchange, such as NYSE and NASDAQ, where the securities are actively traded. Other mutual funds, common collective trusts and limited partnerships are valued using the observable prices of the underlying fund assets based on trade data for identical or similar securities or from a national stock exchange for similar assets or broker quotes. Short-term investment vehicles are funds that invest in short-term fixed income instruments and are valued using observable prices of the underlying fund assets based on trade data for identical or similar securities. Government agency securities are valued using quoted market prices or based on models using observable inputs from market sources such as external prices or spreads or benchmarked thereto. Corporate debt securities and municipals are valued based on recently executed transactions, using quoted market prices, or based on models using observable inputs from market sources such as external prices or spreads or benchmarked thereto. Loans secured by mortgages are valued using observable prices based on trade data for identical or comparable instruments. Hedge funds represent investments in a hedge fund of funds partnership that invests directly in multiple hedge fund strategies that are not traded on exchanges and do not trade on a daily basis. The fair value of this multi-strategy hedge fund is estimated based on the net asset value of the underlying hedge fund strategies using consistent valuation guidelines that account for variations that may impact their fair value. The estimated fair value is the price at which redemptions and subscriptions occur.

Expected Cash Flows

The total benefits expected to be paid from the pension plan or from the Company’s assets for the other postretirement benefits plan (net of participant contributions), respectively, are as follows:

Expected Benefit Payments

Millions of dollars	Pension Benefits		Other Postretirement Benefits

2020-2024	338.4		81.8

Pension Plan Contributions

The pension trust is adequately funded under current regulations. No contributions have been required since 1997, and as a result of closing the plan to new entrants and freezing benefit accruals in the future, the Company does not anticipate making significant contributions to the pension plan for the foreseeable future.

Net Periodic Benefit Cost

The Company records net periodic benefit cost utilizing beginning of the year assumptions. Disclosures required for these plans are set forth in the following tables.

Components of Net Periodic Benefit Cost

In connection with regulatory orders, in 2013 SCE&G began recovering current pension expense through a rate rider that may be adjusted annually (for retail electric operations) or through cost of service rates (for gas operations). SCE&G is amortizing previously deferred pension costs as further described in Note 2.

Other changes in plan assets and benefit obligations recognized in other comprehensive income (net of tax) were as follows:

Discount rate	5.03	%	4.10%/5.07%		5.25	%	5.19	%	4.19	%	5.35	%

Year achieved	n/a		n/a		n/a		2020		2020		2020

Net periodic benefit cost for the period through September 1, 2013 was determined using a 4.10% discount rate, and net periodic benefit cost after that date was determined using a 5.07% discount rate. Similarly, estimated rates of compensation increase were changed in connection with the September 1, 2013 remeasurement.

The estimated amounts to be amortized from accumulated other comprehensive loss into net periodic benefit cost in 2015 are as follows:

Millions of Dollars	Pension Benefits		Other Postretirement Benefits
Actuarial loss	$	0.5	$	0.1
Prior service cost	0.1		—
Total	$	0.6	$	0.1

The estimated amounts to be amortized from regulatory assets into net periodic benefit cost in 2015 are as follows:

Millions of Dollars	Pension Benefits		Other Postretirement Benefits
Actuarial loss	$	12.3	$	1.9
Prior service cost	3.6		0.3
Total	$	15.9	$	2.2

Other postretirement benefit costs are subject to annual per capita limits pursuant to the plan's design. As a result, the effect of a one-percent increase or decrease in the assumed health care cost trend rate on total service and interest cost is not significant.

Stock Purchase Savings Plan

The Company sponsors a defined contribution plan in which eligible employees may defer up to 75% of eligible earnings subject to certain limits and may diversify their investments. Employee deferrals are fully vested and nonforfeitable at all times. The Company provides 100% matching contributions up to 6% of an employee’s eligible earnings. Total matching contributions made to the plan were $25.8 million in 2014, $23.4 million in 2013 and $22.3 million in 2012 and were made in the form of SCANA common stock.

EMPLOYEE BENEFIT PLANS AND EQUITY COMPENSATION PLAN

Pension and Other Postretirement Benefit Plans

SCE&G participates in SCANA’s noncontributory defined benefit pension plan, which covers substantially all regular, full-time employees hired before January 1, 2014. Benefits are no longer offered to employees hired or rehired after December 31, 2013, and pension benefits for existing participants will no longer accrue for services performed or compensation earned after December 31, 2023. SCANA’s policy has been to fund the plan as permitted by applicable federal income tax regulations, as determined by an independent actuary.

SCANA’s pension plan provides benefits under a cash balance formula for employees hired before January 1, 2000 who elected that option and for all eligible employees hired subsequently. 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. Benefits under the cash balance formula and the final average pay formula will continue to accrue through December 31, 2023, after which date no benefits will be accrued except that participants under the cash balance formula will continue to earn interest credits.

In addition to pension benefits, SCE&G participates in SCANA’s unfunded postretirement health care and life insurance programs which provide benefits to certain active and retired employees. Retirees hired before January 1, 2011 share in a portion of their medical care cost. Employees hired after December 31, 2010 are responsible for the full costs of retiree medical benefits elected by them. 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 same benefit formula applies to all SCANA subsidiaries participating in the parent sponsored plans and, with regard to the pension plan, there are no legally separate asset pools. The postretirement benefit plans are accounted for as multiple employer plans. The information presented below reflects Consolidated SCE&G's portion of the obligations, assets, funded status, net periodic benefit costs, and other information reported for the parent sponsored plans as a whole. The tabular data presented reflects the use of various cost assignment methodologies and participation assumptions based on Consolidated SCE&G's past and current employees and its share of plan assets.

Changes in Benefit Obligations

The measurement date used to determine pension and other postretirement benefit obligations is December 31. Data related to the changes in the projected benefit obligation for pension benefits and the accumulated benefit obligation for other postretirement benefits are presented below.

Benefit obligation, December 31	$	773.7		$	695.7		$	204.1		$	181.7

The accumulated benefit obligation for pension benefits was $747.6 million at the end of 2014 and $673.2 million at the end of 2013. The accumulated pension benefit obligation differs from the projected pension 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: 

	Pension Benefits				Other Postretirement Benefits
	2014		2013		2014		2013
Annual discount rate used to determine benefit obligation	4.20	%	5.03	%	4.30	%	5.19	%
Assumed annual rate of future salary increases for projected benefit obligation	3.00	%	3.00	%	3.00	%	3.75	%

A 7.0% annual rate of increase in the per capita cost of covered health care benefits was assumed for 2014. 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 by $0.9 million at December 31, 2014 and by $1.0 million at December 31, 2013. A one percent decrease in the assumed health care cost trend rate would decrease the postretirement benefit obligation by $0.8 million at December 31, 2014 and by $0.9 million at December 31, 2013.

The pension plan operates with several risk and control procedures, including ongoing reviews of liabilities, investment objectives, levels of diversification, investment managers and performance expectations. The total portfolio is constructed and maintained to provide prudent diversification with regard to the concentration of holdings in individual issues, corporations, or industries.

Transactions involving certain types of investments are prohibited. These include, except where utilized by a hedge fund manager, any form of private equity; commodities or commodity contracts (except for unleveraged stock or bond index futures and currency futures and options); ownership of real estate in any form other than publicly traded securities; short sales, warrants or margin transactions, or any leveraged investments; and natural resource properties. Investments made for the purpose of engaging in speculative trading are also prohibited.

The pension plan asset allocation at December 31, 2014 and 2013 and the target allocation for 2015 are as follows:

	Percentage of Plan Assets
	Target Allocation		At December 31,
Asset Category	2015		2014		2013
Equity Securities	58	%	57	%	59	%
Fixed Income	33	%	34	%	32	%
Hedge Funds	9	%	9	%	9	%

For 2015, the expected long-term rate of return on assets will be 7.50%.  In developing the expected long-term rate of return assumptions, management evaluates the pension plan’s historical cumulative actual returns over several periods, considers the expected active returns across various asset classes and assumes an asset allocation of 58% with equity managers, 33% with fixed income managers and 9% with hedge fund managers. Management regularly reviews such allocations and periodically rebalances the portfolio when considered appropriate. Additional rebalancing may occur subject to funded status improvements as part of the dynamic investment strategy adopted for 2013.

Fair Value Measurements

Assets held by the pension plan are measured at fair value as described below. Assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. At December 31, 2014 and 2013, fair value measurements, and the level within the fair value hierarchy in which the measurements fall, were as follows:

	Fair Value Measurements at Reporting Date Using
Millions of dollars	Total		Level 2		Level 3		Total		Level 1		Level 2		Level 3

	$	784	$	711	$	73	$	792	$	322	$	401	$	69

At December 31, 2014, assets with fair value measurements classified as Level 1 were insignificant. There were no transfers of fair value amounts into or out of Levels 1, 2 or 3 during 2014 or 2013.

The pension plan values common stock, preferred stock and certain mutual funds, where applicable, using unadjusted quoted prices from a national stock exchange, such as NYSE and NASDAQ, where the securities are actively traded. Other mutual funds, common collective trusts and limited partnerships are valued using the observable prices of the underlying fund assets based on trade data for identical or similar securities or from a national stock exchange for similar assets or broker quotes. Short-term investment vehicles are funds that invest in short-term fixed income instruments and are valued using observable prices of the underlying fund assets based on trade data for identical or similar securities. Government agency securities are valued using quoted market prices or based on models using observable inputs from market sources such as external prices or spreads or benchmarked thereto. Corporate debt securities and municipals are valued based on recently executed transactions, using quoted market prices, or based on models using observable inputs from market sources such as external prices or spreads or benchmarked thereto. Loans secured by mortgages are valued using observable prices based on trade data for identical or comparable instruments. Hedge funds represent investments in a hedge fund of funds partnership that invests directly in multiple hedge fund strategies that are not traded on exchanges and do not trade on a daily basis. The fair value of this multi-strategy hedge fund is estimated based on the net asset value of the underlying hedge fund strategies using consistent valuation guidelines that account for variations that may impact their fair value. The estimated fair value is the price at which redemptions and subscriptions occur.

Expected Cash Flows

The total benefits expected to be paid from the pension plan or from SCE&G’s assets for the other postretirement benefits plan (net of participant contributions), respectively, are as follows:

Expected Benefit Payments

Millions of dollars	Pension Benefits		Other Postretirement Benefits
2015	$	63.4	$	9.1
2016	64.5		9.8
2017	65.6		10.4
2018	66.1		10.9
2019	65.1		11.5
2020 - 2024	338.4		64.6

Pension Plan Contributions

The pension trust is adequately funded under current regulations. No contributions have been required since 1997, and as a result of closing the plan to new entrants and freezing benefit accruals in the future, SCE&G does not anticipate making significant contributions to the pension plan for the foreseeable future.

Net Periodic Benefit Cost

SCE&G records net periodic benefit cost utilizing beginning of the year assumptions. Disclosures required for these plans are set forth in the following tables.

Components of Net Periodic Benefit Cost

	Pension Benefits									Other Postretirement Benefits
Millions of dollars	2014			2013			2012			2014		2013		2012
Service cost	$	16.0		$	17.6		$	15.7		$	3.6	$	4.6	$	3.7

In connection with regulatory orders, in 2013 SCE&G began recovering current pension expense through a rate rider that may be adjusted annually (for retail electric operations) or through cost of service rates (for gas operations). SCE&G is amortizing previously deferred pension costs as further described in Note 2.

 Other changes in plan assets and benefit obligations recognized in other comprehensive income (net of tax) were as follows:

	Pension Benefits									Other Postretirement Benefits
Millions of dollars	2014			2013			2012			2014		2013			2012

Significant Assumptions Used in Determining Net Periodic Benefit Cost

	Pension Benefits						Other Postretirement Benefits
	2014		2013		2012		2014		2013		2012
Discount rate	5.03	%	4.10%/5.07%		5.25	%	5.19	%	4.19	%	5.35	%
Expected return on plan assets	8.00	%	8.00	%	8.25	%	n/a		n/a		n/a
Rate of compensation increase	3.00	%	3.75%/3.00%		4.00	%	3.75	%	3.75	%	4.00	%
Health care cost trend rate	n/a		n/a		n/a		7.40	%	7.80	%	8.20	%
Ultimate health care cost trend rate	n/a		n/a		n/a		5.00	%	5.00	%	5.00	%
Year achieved	n/a		n/a		n/a		2020		2020		2020

Net periodic benefit cost for the period through September 1, 2013, was determined using a 4.10% discount rate, and net periodic benefit cost after that date was determined using a 5.07% discount rate. Similarly, estimated rates of compensation increase were changed in connection with the September 1, 2013 remeasurement.

The actuarial loss and prior service cost to be amortized from accumulated other comprehensive loss into net periodic benefit cost in 2015 are insignificant. 

The estimated amounts to be amortized from regulatory assets into net periodic benefit cost in 2015 are as follows:

Millions of Dollars	Pension Benefits		Other Postretirement Benefits
Actuarial loss	$	10.6	$	1.6
Prior service cost	3.1		0.2
Total	$	13.7	$	1.8

Other postretirement benefit costs are subject to annual per capita limits pursuant to the plan's design. As a result, the effect of a one-percent increase or decrease in the assumed health care cost trend rate on total service and interest cost is not significant.

Stock Purchase Savings Plan

SCE&G participates in a SCANA-sponsored defined contribution plan in which eligible employees may defer up to 75% of eligible earnings subject to certain limits and may diversify their investments. Employee deferrals are fully vested and nonforfeitable at all times. SCE&G provides 100% matching contributions up to 6% of an employee’s eligible earnings. Total matching contributions made to the plan were $20.7 million in 2014, $18.7 million in 2013 and $17.7 million in 2012 and were made in the form of SCANA common stock.
