We are currently evaluating whether we will apply the optional guidance as we assess the impact of the discontinuance of LIBOR on our current arrangements and the potential impact on our financial position, results of operations and cash flows. </span></div></ix:nonNumeric></ix:continuation><div><span><br/></span></div><div><span><br/></span></div><div><span><br/></span></div><div style="height:42.75pt;position:relative;width:100%"><div style="bottom:0;position:absolute;width:100%"><div style="text-align:center"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">14</span></div><div style="text-align:center"><span><br/></span></div></div></div><hr style="page-break-after:always"/><div style="min-height:42.75pt;width:100%"><div><span style="color:#0000ff;font-family:'Arial',sans-serif;font-size:9pt;font-weight:700;line-height:120%;text-decoration:underline"><a style="color:#0000ff;font-family:'Arial',sans-serif;font-size:9pt;font-weight:700;line-height:120%;text-decoration:underline" href="#i5cda1a4bbd9145a7aafdec5a10e751cb_7">Table of Contents</a></span></div></div><ix:continuation id="i677a6c9cc9b549eab4c5d8f922424ec6"><ix:continuation id="i49229a1f63794f918a2b7c4055fbfe60"><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:700;line-height:120%">Recently Adopted Accounting Standards</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline">Simplifying the Accounting for Income Taxes, ASU 2019-12</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">In December 2019, the FASB issued ASU 2019-12, </span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%">Simplifying the Accounting for Income Taxes</span><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"> as part of its overall simplification initiative to reduce costs and complexity in applying accounting standards while maintaining or improving the usefulness of the information provided to users of the financial statements.

A portion of our over-the-counter swaps have been designated as cash flow hedges to mitigate the commodity price risk associated with deliveries under fixed price forward contracts to deliver gas to our Choice Gas Program customers. The gain or loss on these designated derivatives is reported in AOCI in the accompanying Condensed Consolidated Balance Sheets and reclassified into earnings in the same period that the underlying hedged item is recognized in earnings.

For exchange-traded futures, options and basis swap assets and liabilities, fair value was derived using broker quotes validated by the exchange settlement pricing for the applicable contract. For over-the-counter instruments, the fair value is obtained by utilizing a nationally recognized service that obtains observable inputs to compute the fair value, which we validate by comparing our valuation with the counterparty. The fair value of these swaps includes a CVA based on the credit spreads of the counterparties when we are in an unrealized gain position or on our own credit spread when we are in an unrealized loss position.

Our Electric Utilities incurred a $3.2 million negative impact to regulated wholesale power margins due to higher fuel costs and $2.1 million of incremental fuel costs that are not recoverable through our fuel cost recovery mechanisms. Black Hills Energy Services offers fixed contract pricing for non-regulated gas supply services to our regulated natural gas customers and $8.2 million of increased cost of natural gas sold during Winter Storm Uri is not recoverable through the regulatory construct. Additionally, we incurred $0.7 million of interest expense for the three months ended March 31, 2021, related to our $800 million term loan. Our non-regulated Power Generation segment benefited from a $1.7&#160;million favorable impact to operating income from Winter Storm Uri.

Significant earnings variances can be expected between the Gas Utilities segment&#8217;s peak and off-peak seasons.

As a result of Winter Storm Uri, our net pre-tax incremental fuel, purchased power and natural gas costs during the three months ended March 31, 2021 were approximately $571&#160;million. This amount does not include potential pipeline transportation charges for certain suppliers who have requested and received approval from FERC to delay billings.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Our Utilities have regulatory mechanisms to recover approximately $559 million of incremental costs from Winter Storm Uri. However, given the extraordinary impact of these higher costs to our customers, our regulators are performing a heightened review. We are engaged with our regulators to identify appropriate periods over which to recover incremental costs with consideration of the impacts to our customers&#x2019; bills. We expect to recover most of the Winter Storm Uri incremental costs through a separately tracked regulatory mechanism but we also anticipate recovery of a portion of the costs through existing mechanisms.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;For the three months ended March 31, 2021, we expensed $12.5&#160;million of Winter Storm Uri net incremental costs as a result of negative impacts to our Utilities and financing costs partially offset by favorable impacts to our Power Generation segment. Our Electric Utilities incurred a $3.2&#160;million negative impact to our regulated wholesale power margins due to higher fuel costs and $2.1&#160;million of incremental fuel costs that are not recoverable through our fuel cost recovery mechanisms. Black Hills Energy Services offers fixed contract pricing for non-regulated gas supply services to our regulated natural gas customers and the $8.2&#160;million increase in cost of natural gas sold during Winter Storm Uri is not recoverable through the regulatory construct. Additionally, we incurred $0.7&#160;million of interest expense for the three months ended March 31, 2021, related to our $800&#160;million term loan which is discussed in &lt;/span&gt;&lt;span style="color:#0000ff;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;&lt;a href="#i5cda1a4bbd9145a7aafdec5a10e751cb_70" style="color:#0000ff;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Note 5&lt;/a&gt;&lt;/span&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;.

Final rates were enacted on March 1, 2021, which replaced interim rates effective September 1, 2020. The approval shifted $4.6&#160;million of SSIR revenue to base rates and is expected to generate $6.5&#160;million in new annual revenue with a capital structure of 50% equity and 50% debt and an authorized return on equity of 9.5%. The approval also includes an extension of the SSIR for five years and an expansion of this mechanism across the consolidated jurisdictions.&lt;/span&gt;&lt;/div&gt;</us-gaap:ScheduleOfRegulatoryAssetsAndLiabilitiesTextBlock>

style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;On February 24, 2021, we entered into a nine-month, $800&#160;million unsecured term loan to provide additional liquidity and meet our cash needs related to the incremental fuel, purchased power and natural gas costs from Winter Storm Uri. The term loan, which matures on November 24, 2021, has an interest rate based on LIBOR plus 75 basis points, carries no prepayment penalty and is subject to the same covenant requirements as our Revolving Credit Facility. We repaid $200&#160;million of this term loan in the first quarter of 2021. The interest rate on term loan borrowings on March 31, 2021 was 0.86%.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;We expect to refinance a portion of the term loan with longer-term debt prior to maturity. In the event we are unable to refinance the remaining obligation, we believe it is probable that our current plans to manage liquidity would be sufficient to meet our obligations.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Revolving Credit Facility and CP Program&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Our net short-term borrowings related to our Revolving Credit Facility and CP Program during the three months ended March 31, 2021 decreased by $18 million.

Our Consolidated Indebtedness to Capitalization Ratio was calculated by dividing (i) consolidated indebtedness, which includes letters of credit and certain guarantees issued, by (ii) capital, which includes consolidated indebtedness plus consolidated net worth, which excludes noncontrolling interest in subsidiaries. Subject to applicable cure periods, a violation of any of these covenants would constitute an event of default that entitles the lenders to terminate their remaining commitments and accelerate all principal and interest outstanding.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Our Revolving Credit Facility and term loans require compliance with the following financial covenant, which we were in compliance with at March 31, 2021:&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:5pt;text-align:center"&gt;&lt;table style="border-collapse:collapse;display:inline-table;margin-bottom:5pt;vertical-align:text-bottom;width:99.853%"&gt;&lt;tr&gt;&lt;td style="width:1.0%"/&gt;&lt;td style="width:54.097%"/&gt;&lt;td style="width:0.1%"/&gt;&lt;td style="width:1.0%"/&gt;&lt;td style="width:21.886%"/&gt;&lt;td style="width:0.1%"/&gt;&lt;td style="width:0.1%"/&gt;&lt;td style="width:0.824%"/&gt;&lt;td style="width:0.1%"/&gt;&lt;td style="width:1.0%"/&gt;&lt;td style="width:8.709%"/&gt;&lt;td style="width:0.1%"/&gt;&lt;td style="width:1.0%"/&gt;&lt;td style="width:9.884%"/&gt;&lt;td style="width:0.1%"/&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td colspan="3" style="padding:0 1pt"/&gt;&lt;td colspan="3" style="padding:2px 1pt;text-align:center;vertical-align:top"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:100%"&gt;As of March 31, 2021&lt;/span&gt;&lt;/td&gt;&lt;td colspan="3" style="padding:0 1pt"/&gt;&lt;td colspan="6" style="padding:2px 1pt;text-align:center;vertical-align:top"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:100%"&gt;Covenant Requirement&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td colspan="3" style="background-color:#ceffe7;padding:2px 1pt;text-align:left;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:100%"&gt;Consolidated Indebtedness to Capitalization Ratio&lt;/span&gt;&lt;/td&gt;&lt;td colspan="3" style="background-color:#ceffe7;border-top:1pt solid #000000;padding:2px 1pt;text-align:center;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:100%"&gt;62.6%&lt;/span&gt;&lt;/td&gt;&lt;td colspan="3" style="background-color:#ceffe7;border-top:1pt solid #000000;padding:0 1pt"/&gt;&lt;td colspan="3" style="background-color:#ceffe7;border-top:1pt solid #000000;padding:2px 1pt;text-align:right;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:100%"&gt;Less than&lt;/span&gt;&lt;/td&gt;&lt;td colspan="3" style="background-color:#ceffe7;border-top:1pt solid #000000;padding:2px 1pt;text-align:center;vertical-align:bottom"&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:100%"&gt;65%&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;</us-gaap:DebtDisclosureTextBlock>

When the related costs are recovered through our rates, the hedging activity is recognized in the Condensed Consolidated Statements of Income.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;We periodically use wholesale power purchase and sale contracts to manage purchased power costs and load requirements associated with serving our electric customers that are considered derivative instruments due to not qualifying for the normal purchases and normal sales exception to derivative accounting. Changes in the fair value of these commodity derivatives are recognized in the Condensed Consolidated Statements of Income.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;We buy, sell and deliver natural gas at competitive prices by managing commodity price risk. As a result of these activities, this area of our business is exposed to risks associated with changes in the market price of natural gas. We manage our exposure to such risk using over-the-counter and exchange traded options and swaps with counterparties in anticipation of forecasted purchases and sales during time frames ranging from April 2021 through August 2023. A portion of our over-the-counter swaps have been designated as cash flow hedges to mitigate the commodity price risk associated with deliveries under fixed price forward contracts to deliver gas to our Choice Gas Program customers. The gain or loss on these designated derivatives is reported in AOCI in the accompanying Condensed Consolidated Balance Sheets and reclassified into earnings in the same period that the underlying hedged item is recognized in earnings. Effectiveness of our hedging position is evaluated at least quarterly.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The contract or notional amounts and terms of the electric and natural gas derivative commodity instruments held at our Utilities are composed of both long and short positions.

as cash flow hedges. There is no earnings impact because the unrealized gains and losses arising from the use of these financial instruments are recorded as Regulatory assets or Regulatory liabilities. The net unrealized losses included in our Regulatory asset or Regulatory liability  related to the hedges in our Gas Utilities were $0.3 million and $2.2 million as of March 31, 2021 and December 31, 2020, respectively.

Transfers out of Level 3, if any, occur when the significant inputs become more observable, such as when the time between the valuation date and the delivery date of a transaction becomes shorter, positively impacting the availability of observable pricing inputs.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Recurring Fair Value Measurements&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%"&gt;Derivatives&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The commodity contracts for our Utilities segments are valued using the market approach and include forward strip pricing at liquid delivery points, exchange-traded futures, options, basis swaps and over-the-counter swaps and options (Level 2) for wholesale electric energy and natural gas contracts. For exchange-traded futures, options and basis swap assets and liabilities, fair value was derived using broker quotes validated by the exchange settlement pricing for the applicable contract. For over-the-counter instruments, the fair value is obtained by utilizing a nationally recognized service that obtains observable inputs to compute the fair value, which we validate by comparing our valuation with the counterparty. The fair value of these swaps includes a CVA based on the credit spreads of the counterparties when we are in an unrealized gain position or on our own credit spread when we are in an unrealized loss position.

For exchange-traded futures, options and basis swap assets and liabilities, fair value was derived using broker quotes validated by the exchange settlement pricing for the applicable contract. For over-the-counter instruments, the fair value is obtained by utilizing a nationally recognized service that obtains observable inputs to compute the fair value, which we validate by comparing our valuation with the counterparty. The fair value of these swaps includes a CVA based on the credit spreads of the counterparties when we are in an unrealized gain position or on our own credit spread when we are in an unrealized loss position.

We expect to recover these costs from customers over several years. Winter Storm Uri costs, which will be deductible in our 2021 tax return, created a net deferred tax liability of approximately $132&#160;million at March 31, 2021. The deferred tax liability will reverse with the same timing as the costs are recovered from our customers.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;The income tax deduction recognized from Winter Storm Uri will create an NOL in our 2021 federal and state income tax returns. Our federal NOL carryforwards no longer expire due to the TCJA; however, our state NOL carryforwards expire at various dates from 2021 to 2040. We do not anticipate material changes to our valuation allowance against the state NOL carryforwards from Winter Storm Uri. Therefore, we did not record an additional valuation allowance against the state NOL carryforwards as of March 31, 2021.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:700;line-height:120%"&gt;Income Tax Benefit (Expense) and Effective Tax Rates&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Three Months Ended March 31, 2021 Compared to the Three Months Ended March 31, 2020&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%"&gt;Income tax (expense) for the three months ended March 31, 2021 was $(0.5) million compared to $(16) million reported for the same period in 2020. For the three months ended March 31, 2021 the effective tax rate was 0.5% compared to 14.1% for the same period in 2020. The lower effective tax rate is primarily due to $7.6&#160;million of increased tax benefits from Colorado Electric&#x2019;s TCJA-related bill credits to customers (which is offset by reduced revenue), $1.5&#160;million of increased tax benefits from amortization of excess deferred income taxes and $1.3&#160;million of increased tax benefits from federal production tax credits associated with new wind assets.&lt;/span&gt;&lt;/div&gt;</us-gaap:IncomeTaxDisclosureTextBlock>

Such costs are capitalized if they meet both of the following criteria: a. It is probable that future revenue in an amount at least equal to the capitalized cost will result from inclusion of that cost in allowable costs for rate-making purposes. b. Based on available evidence, the future revenue will be provided to permit recovery of the previously incurred cost rather than to provide for expected levels of similar future costs. If the revenue will be provided through an automatic rate-adjustment clause, this criterion requires that the regulator's intent clearly be to permit recovery of the previously incurred cost.</p></div>

As a result of Winter Storm Uri, our net pre-tax incremental fuel, purchased power and natural gas costs during the three months ended March 31, 2021 were approximately $571&#160;million.

However, given the extraordinary impact of these higher costs to our customers, our regulators are performing a heightened review. We are engaged with our regulators to identify appropriate periods over which to recover incremental costs with consideration of the impacts to our customers&#8217; bills.

Our Electric Utilities incurred a $3.2&#160;million negative impact to our regulated wholesale power margins due to higher fuel costs and $2.1&#160;million of incremental fuel costs that are not recoverable through our fuel cost recovery mechanisms. Black Hills Energy Services offers fixed contract pricing for non-regulated gas supply services to our regulated natural gas customers and the $8.2&#160;million increase in cost of natural gas sold during Winter Storm Uri is not recoverable through the regulatory construct.

Therefore, as allowed or required by state regulatory commissions, we have entered into commission-approved hedging programs utilizing natural gas futures, options, over-the-counter swaps and basis swaps to reduce our customers&#8217; underlying exposure to these fluctuations.

A portion of our over-the-counter swaps have been designated as cash flow hedges to mitigate the commodity price risk associated with deliveries under fixed price forward contracts to deliver gas to our Choice Gas Program customers.

cash flow hedges. There is no earnings impact because the unrealized gains and losses arising from the use of these financial instruments are recorded as Regulatory assets or Regulatory liabilities. The net unrealized losses included in our Regulatory asset or Regulatory liability  related to the hedges in our Gas Utilities were $0.3 million and $2.2 million as of March 31, 2021 and December 31, 2020, respectively. For our Electric Utilities, the unrealized gains and losses arising from these derivatives are recognized in the Condensed Consolidated Statements of Income.</span></div><span></span>

These inputs reflect management&#8217;s best estimate of fair value using its own assumptions about the assumptions a market participant would use in pricing the asset or liability.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the placement within the fair value hierarchy levels. We record transfers, if necessary, between levels at the end of the reporting period for all of our financial instruments.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Transfers into Level 3, if any, occur when significant inputs used to value the derivative instruments become less observable, such as a significant decrease in the frequency and volume in which the instrument is traded, negatively impacting the availability of observable pricing inputs. Transfers out of Level 3, if any, occur when the significant inputs become more observable, such as when the time between the valuation date and the delivery date of a transaction becomes shorter, positively impacting the availability of observable pricing inputs.</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline">Recurring Fair Value Measurements</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-style:italic;font-weight:400;line-height:120%">Derivatives</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">The commodity contracts for our Utilities segments are valued using the market approach and include forward strip pricing at liquid delivery points, exchange-traded futures, options, basis swaps and over-the-counter swaps and options (Level 2) for wholesale electric energy and natural gas contracts. For exchange-traded futures, options and basis swap assets and liabilities, fair value was derived using broker quotes validated by the exchange settlement pricing for the applicable contract. For over-the-counter instruments, the fair value is obtained by utilizing a nationally recognized service that obtains observable inputs to compute the fair value, which we validate by comparing our valuation with the counterparty. The fair value of these swaps includes a CVA based on the credit spreads of the counterparties when we are in an unrealized gain position or on our own credit spread when we are in an unrealized loss position.

We do not anticipate material changes to our valuation allowance against the state NOL carryforwards from Winter Storm Uri. Therefore, we did not record an additional valuation allowance against the state NOL carryforwards as of March 31, 2021.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:700;line-height:120%">Income Tax Benefit (Expense) and Effective Tax Rates</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%;text-decoration:underline">Three Months Ended March 31, 2021 Compared to the Three Months Ended March 31, 2020</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Income tax (expense) for the three months ended March 31, 2021 was $(0.5) million compared to $(16) million reported for the same period in 2020. For the three months ended March 31, 2021 the effective tax rate was 0.5% compared to 14.1% for the same period in 2020. The lower effective tax rate is primarily due to $7.6&#160;million of increased tax benefits from Colorado Electric&#8217;s TCJA-related bill credits to customers (which is offset by reduced revenue), $1.5&#160;million of increased tax benefits from amortization of excess deferred income taxes and $1.3&#160;million of increased tax benefits from federal production tax credits associated with new wind assets.</span></div><span></span>

<td class="text"><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:9pt;font-weight:400;line-height:120%">The commodity contracts for our Utilities segments are valued using the market approach and include forward strip pricing at liquid delivery points, exchange-traded futures, options, basis swaps and over-the-counter swaps and options (Level 2) for wholesale electric energy and natural gas contracts. For exchange-traded futures, options and basis swap assets and liabilities, fair value was derived using broker quotes validated by the exchange settlement pricing for the applicable contract. For over-the-counter instruments, the fair value is obtained by utilizing a nationally recognized service that obtains observable inputs to compute the fair value, which we validate by comparing our valuation with the counterparty. The fair value of these swaps includes a CVA based on the credit spreads of the counterparties when we are in an unrealized gain position or on our own credit spread when we are in an unrealized loss position. For additional information, see Note 1 of our Notes to the Consolidated Financial Statements in our 2020 Annual Report on Form 10-K.</span></div><div style="margin-top:5pt;text-align:center"><table

Such costs are capitalized if they meet both of the following criteria: a.

Based on available evidence, the future revenue will be provided to permit recovery of the previously incurred cost rather than to provide for expected levels of similar future costs. If the revenue will be provided through an automatic rate-adjustment clause, this criterion requires that the regulator's intent clearly be to permit recovery of the previously incurred cost.</p></div>
