Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items]

The fair values of our financial instruments are based on published sources for pricing when possible. We rely on valuation models only when no other methods exist. The value of our financial instruments represents our best estimates of the fair value, which may not be the value realized in the future.

The following table presents the fair value and cost of our non-derivative instruments at June 30, 2015 and December 31, 2014. Information about the fair value of our derivative instruments can be found in Note 9.

Liabilities
Debt	$	2,159.8	$	2,235.3	$	2,159.7	$	2,204.8

These financial instruments are not subject to master netting agreements or collateral requirements and as such are presented in the Condensed Consolidated Balance Sheet at their gross fair value, except for Debt, which is presented at amortized carrying value.

Debt

Unrealized gains or losses are not recognized in the financial statements as debt is presented at the carrying value, net of unamortized premium or discount in the financial statements. The debt amounts include the current portion payable in the next twelve months and have maturities that range from 2016 to 2061.

Master Trust Assets

DP&L established Master Trusts to hold assets that could be used for the benefit of employees participating in employee benefit plans and these assets are not used for general operating purposes. These assets are primarily comprised of open-ended mutual funds, which are valued using the net asset value per unit. These investments are recorded at fair value within Other deferred assets on the balance sheets and classified as available-for-sale. Any unrealized gains or losses are recorded in AOCI until the securities are sold.

DPL had $0.9 million ($0.6 million after tax) and $0.8 million ($0.5 million after tax) of unrealized gains and immaterial unrealized losses on the Master Trust assets in AOCI at June 30, 2015 and at December 31, 2014, respectively.

During the six months ended June 30, 2015, $0.6 million ($0.4 million after tax) of various investments were sold to facilitate the distribution of benefits and the unrealized gains were reversed into earnings. An immaterial amount of unrealized gains are expected to be reversed to earnings over the next twelve months to facilitate the distribution of benefits.

Fair Value Hierarchy

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. These inputs are then categorized as:


•	Level 1 (quoted prices in active markets for identical assets or liabilities);


•	Level 2 (observable inputs such as quoted prices for similar assets or liabilities or quoted prices in markets that are not active);


•	Level 3 (unobservable inputs).

Valuations of assets and liabilities reflect the value of the instrument including the values associated with counterparty risk. We include our own credit risk and our counterparty’s credit risk in our calculation of fair value using global average default rates based on an annual study conducted by a large rating agency.

We did not have any transfers of the fair values of our financial instruments between Level 1 and Level 2 of the fair value hierarchy during the three months and six months ended June 30, 2015 and 2014.

The fair value of assets and liabilities at June 30, 2015 and December 31, 2014 and the respective category within the fair value hierarchy for DPL was determined as follows:

Total Liabilities	$	2,217.0	$	0.5	$	2,197.7	$	18.8

Our financial instruments are valued using the market approach in the following categories:


•	Level 1 inputs are used for derivative contracts such as heating oil futures and for money market accounts that are considered cash equivalents. The fair value is determined by reference to quoted market prices and other relevant information generated by market transactions.


•	Level 2 inputs are used to value derivatives such as forward power contracts (which are traded on the OTC market but which are valued using prices on the NYMEX for similar contracts on the OTC market). Other Level 2 assets include open-ended mutual funds that are in the Master Trust, which are valued using observable prices based on the end of day NAV per unit.


•	Level 3 inputs such as FTRs are considered a Level 3 input because the monthly auctions are considered inactive. Other Level 3 inputs include the credit valuation adjustment on some of the forward power contracts and forward power contracts in less active markets. Our Level 3 inputs are immaterial to our derivative balances as a whole and as such no further disclosures are presented.

Approximately 96% of the inputs to the fair value of our derivative instruments are from quoted market prices.

Our debt is fair valued for disclosure purposes only and most of the fair values are determined using quoted market prices in inactive markets. These fair value inputs are considered Level 2 in the fair value hierarchy. As the Wright-Patterson Air Force Base loan is not publicly traded, fair value is assumed to equal carrying value. These fair value inputs are considered Level 3 in the fair value hierarchy as there are no observable inputs. Additional Level 3 disclosures are not presented since debt is not recorded at fair value.

Non-recurring Fair Value Measurements

We use the cost approach to determine the fair value of our AROs, which is estimated by discounting expected cash outflows to their present value at the initial recording of the liability. Cash outflows are based on the approximate future disposal cost as determined by market information, historical information or other management estimates. These inputs to the fair value of the AROs would be considered Level 3 inputs under the fair value hierarchy. AROs for ash ponds, asbestos, river structures and underground storage tanks increased by $39.8 million and $1.2 million during the six months ended June 30, 2015 and 2014, respectively. The majority of the increase in 2015 is due to an increase in the AROs for ash ponds ($40.6 million) as a result of new rules promulgated by the USEPA that were published in the Federal Register in April 2015 and will become effective in October 2015.

When evaluating impairment of goodwill and long-lived assets, we measure fair value using the applicable fair value measurement guidance. Impairment expense is measured by comparing the fair value at the evaluation date to the carrying amount. The following table summarizes Goodwill and Long-lived assets measured at fair value on a non-recurring basis during the period and their level within the fair value hierarchy (there were no impairments during the six months ended June 30, 2015):

Master Trust Assets

DP&L established Master Trusts to hold assets that could be used for the benefit of employees participating in employee benefit plans and these assets are not used for general operating purposes. These assets are primarily comprised of open-ended mutual funds that are valued using the net asset value per unit. These investments are recorded at fair value within Other deferred assets on the balance sheets and classified as available-for-sale. Any unrealized gains or losses are recorded in AOCI until the securities are sold.

DP&L had $1.0 million ($0.6 million after tax) and $1.1 million ($0.7 million after tax) in unrealized gains and immaterial unrealized losses on the Master Trust assets in AOCI at June 30, 2015 and at December 31, 2014, respectively.

Fair Value Hierarchy


•	Level 1 (quoted prices in active markets for identical assets or liabilities);


•	Level 2 (observable inputs such as quoted prices for similar assets or liabilities or quoted prices in markets that are not active);


•	Level 3 (unobservable inputs).

The fair value of assets and liabilities at June 30, 2015 and December 31, 2014 and the respective category within the fair value hierarchy for DP&L was determined as follows:

Non-recurring Fair Value Measurements

We use the cost approach to determine the fair value of our AROs, which is estimated by discounting expected cash outflows to their present value at the initial recording of the liability. Cash outflows are based on the approximate future disposal cost as determined by market information, historical information or other management estimates. AROs for ash ponds, asbestos, river structures and underground storage tanks increased by $39.8 million and $1.2 million during the six months ended June 30, 2015 and 2014, respectively. The majority of the increase in 2015 is due to an increase in the AROs for ash ponds ($40.6 million) due to new rules promulgated by the USEPA that were published in the Federal Register in April 2015 and will become effective in October 2015.
