Fair Value of Financial Assets and Liabilities

Fair Value Measurements

The accounting guidance for fair value measurements and disclosures provides a single definition of fair value, hierarchical framework for measuring assets and liabilities and requires disclosure about assets and liabilities measured at fair value.

Level 1 — Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. The types of assets and liabilities included in Level 1 are highly liquid and actively traded instruments with quoted prices.

Level 2 — Pricing inputs are other than quoted prices in active markets, but are either directly or indirectly observable as of the reporting date. The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, or priced with models using highly observable inputs.

Level 3 — Significant inputs to pricing have little or no observability as of the reporting date. The types of assets and liabilities included in Level 3 are those valued with models requiring significant management judgment or estimation.

Specific valuation methods include:

Cash equivalents — The fair values of cash equivalents are generally based on cost plus accrued interest; money market funds are measured using quoted NAVs.

Interest rate derivatives — The fair values of interest rate derivatives are based on broker quotes that utilize current market interest rate forecasts.

Commodity derivatives — The methods used to measure the fair value of commodity derivative forwards and options generally utilize observable forward prices and volatilities, as well as observable pricing adjustments for specific delivery locations, and are generally assigned a Level 2 classification.

When contractual settlements relate to delivery locations for which pricing is relatively unobservable, or extend to periods beyond those readily observable on active exchanges or quoted by brokers, the significance of the use of less observable inputs on a valuation is evaluated, and may result in Level 3 classification.

Derivative Instruments Fair Value Measurements

NSP-Wisconsin enters into derivative instruments, including forward contracts, futures, swaps and options, for trading purposes and to manage risk in connection with changes in interest rates and utility commodity prices.

Interest Rate Derivatives — NSP-Wisconsin may enter into various instruments that effectively fix the yield or price on a specified benchmark interest rate for an anticipated debt issuance for a specific period. These derivative instruments are generally designated as cash flow hedges for accounting purposes.

At June 30, 2019, accumulated other comprehensive loss related to interest rate derivatives included no net gains or losses expected to be reclassified into earnings during the next 12 months as the related hedged interest rate transactions impact earnings, including forecasted amounts for unsettled hedges, as applicable.

Commodity Derivatives — NSP-Wisconsin may enter into derivative instruments to manage variability of future cash flows from changes in commodity prices in its electric and natural gas operations, as well as for trading purposes. This could include the purchase or sale of natural gas to generate electric energy and natural gas for resale.

Gross notional amounts of commodity options:


^(a)	Amounts are not reflective of net positions in the underlying commodities.


^(b)	Notional amounts for options are included on a gross basis, but are weighted for the probability of exercise.

Consideration of Credit Risk and Concentrations — NSP-Wisconsin continuously monitors the creditworthiness of counterparties to its interest rate derivatives and commodity derivative contracts prior to settlement, and assesses each counterparty’s ability to perform on the transactions set forth in the contracts. Impact of credit risk was immaterial to the fair value of unsettled commodity derivatives presented in the consolidated balance sheets.

Impact of Derivative Activities on Income and Accumulated Other Comprehensive Loss — There were no pre-tax gains or losses related to interest rate derivatives reclassified from accumulated other comprehensive loss into earnings for the three and six months ended June 30, 2019. There were immaterial pre-tax losses and $0.1 million of net losses reclassified from accumulated other comprehensive loss into earnings during the three and six months ended June 30, 2018, respectively.

Changes in the fair value of natural gas commodity derivatives resulted in immaterial net losses for both the three months ended June 30, 2019 and 2018, which were recognized as regulatory assets and liabilities. There were $0.1 million of net losses and immaterial net losses for the six months ended June 30, 2019 and 2018, respectively. The classification as a regulatory asset or liability is based on commission approved regulatory recovery mechanisms.

During both the three months ended June 30, 2019 and 2018, there were no settlement gains or losses on natural gas commodity derivatives, which were recognized subject to purchased natural gas cost recovery mechanisms, which result in reclassifications of derivative settlement gains and losses out of income to a regulatory asset or liability, as appropriate. There were $0.2 million of gains and no gains or losses for the six months ended June 30, 2019 and 2018, respectively.

NSP-Wisconsin had no derivative instruments designated as fair value hedges during the three and six months ended June 30, 2019 and 2018.

Recurring Fair Value Measurements — The following tables presents for each of the fair value hierarchy levels, NSP-Wisconsin's derivative assets and liabilities measured at fair value on a recurring basis:



	June 30, 2019
	Fair Value						Fair Value Total		Netting ^(a)		Total ^(b)
(Millions of Dollars)	Level 1		Level 2		Level 3		Fair Value Total		Netting ^(a)		Total ^(b)
Current derivative assets
Natural gas commodity	$	—	$	0.1	$	—	$	0.1	$	—	$	0.1



	Dec. 31, 2018
	Fair Value						Fair Value Total		Netting ^(a)		Total ^(b)
(Millions of Dollars)	Level 1		Level 2		Level 3		Fair Value Total		Netting ^(a)		Total ^(b)
Current derivative assets
Natural gas commodity	$	—	$	0.2	$	—	$	0.2	$	—	$	0.2

^(a)

NSP-Wisconsin nets derivative instruments and related collateral in its consolidated balance sheet when supported by a legally enforceable master netting agreement, and all derivative instruments and related collateral amounts were subject to master netting agreements at June 30, 2019 and Dec. 31, 2018. The counterparty netting amounts presented exclude settlement receivables and payables and non-derivative amounts that may be subject to the same master netting agreements.


^(b)	Included in prepayments and other current assets balance of $3.2 million at June 30, 2019 and $3.3 million at Dec. 31, 2018 in the consolidated balance sheets.

Fair Value of Long-Term Debt

Other financial instruments for which the carrying amount did not equal fair value:



	June 30, 2019				Dec. 31, 2018
(Millions of Dollars)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-term debt, including current portion	$	807.8	$	912.2	$	807.5	$	850.4

Fair value of NSP-Wisconsin’s long-term debt is estimated based on recent trades and observable spreads from benchmark interest rates for similar securities. Fair value estimates are based on information available to management as of June 30, 2019 and Dec. 31, 2018, and given the observability of the inputs, fair values presented for long-term debt were assigned as Level 2.
