The final rule contains three main components: (1) a definition for legacy CCR surface impoundments, which are inactive surface impoundments at inactive generating facilities that must adhere to the same regulations as inactive CCR impoundments at active generating facilities, barring location restrictions and liner design criteria, with customized compliance deadlines; (2) groundwater monitoring, corrective action, closure, and post closure care requirements for CCRMUs, which may be located at active generating facilities and inactive generating facilities with a legacy CCR surface impoundment; and (3) the owners and operators of inactive generating facilities must identify the presence of legacy CCR surface impoundments and comply with all rule requirements for surface impoundments; and the owners and operators of active generating facilities and inactive generating facilities with a legacy CCR surface impoundment must prepare Facility Evaluation Reports ("FERs") that identify and describe the CCRMUs and determine whether closure is required. In a manner consistent with existing CCR rules, owners and operators must publish FERs on their CCR websites in two parts, within 15 months (Part 1) and 27 months (Part 2) of the final rule's effective date in November 2024.

Risk Management and Hedging Activities	Risk Management and Hedging Activities PacifiCorp is exposed to the impact of market fluctuations in commodity prices and interest rates. PacifiCorp is principally exposed to electricity, natural gas, coal and fuel oil commodity price risk as it has an obligation to serve retail customer load in its service territories. PacifiCorp's load and generating facilities represent substantial underlying commodity positions. Exposures to commodity prices consist mainly of variations in the price of fuel required to generate electricity and wholesale electricity that is purchased and sold. Commodity prices are subject to wide price swings as supply and demand are impacted by, among many other unpredictable items, weather, market liquidity, generating facility availability, customer usage, storage, and transmission and transportation constraints. Interest rate risk exists on variable-rate debt and future debt issuances. PacifiCorp does not engage in a material amount of proprietary trading activities. PacifiCorp has established a risk management process that is designed to identify, assess, manage and report on each of the various types of risk involved in its business. To mitigate a portion of its commodity price risk, PacifiCorp uses commodity derivative contracts, which may include forwards, futures, options, swaps and other agreements, to effectively secure future supply or sell future production generally at fixed prices. PacifiCorp manages its interest rate risk by limiting its exposure to variable interest rates primarily through the issuance of fixed-rate long-term debt and by monitoring market changes in interest rates. Additionally, PacifiCorp has the ability to enter into interest rate derivative contracts, such as interest rate swaps or locks, to mitigate PacifiCorp's exposure to interest rate risk. No interest rate derivatives were in place during the periods presented. PacifiCorp does not hedge all of its commodity price and interest rate risks, thereby exposing the unhedged portion to changes in market prices. Refer to Note 10 for additional information on derivative contracts. The following table, which reflects master netting arrangements and excludes contracts that have been designated as normal under the normal purchases or normal sales exception afforded by GAAP, summarizes the fair value of PacifiCorp's derivative contracts, on a gross basis, and reconciles those amounts to the amounts presented on a net basis on the Consolidated Balance Sheets (in millions): Derivative Contracts - Other Other Current Other Current Long-term Assets Assets Liabilities Liabilities Total As of June 30, 2024 Not designated as hedging contracts (1) : Commodity assets $ 5 $ 5 $ 14 $ 3 $ 27 Commodity liabilities — (2) (148) (16) (166) Total 5 3 (134) (13) (139) Total derivatives 5 3 (134) (13) (139) Cash collateral receivable — — 48 — 48 Total derivatives - net basis $ 5 $ 3 $ (86) $ (13) $ (91) As of December 31, 2023 Not designated as hedging contracts (1) : Commodity assets $ 21 $ 2 $ 7 $ 2 $ 32 Commodity liabilities (3) — (83) (22) (108) Total 18 2 (76) (20) (76) Total derivatives 18 2 (76) (20) (76) Cash collateral receivable (2) — 12 — 10 Total derivatives - net basis $ 16 $ 2 $ (64) $ (20) $ (66) (1) PacifiCorp's commodity derivatives are generally included in rates.

Credit risk may be concentrated to the extent PacifiCorp's counterparties have similar economic, industry or other characteristics and due to direct or indirect relationships among the counterparties. Before entering into a transaction, PacifiCorp analyzes the financial condition of each significant wholesale counterparty, establishes limits on the amount of unsecured credit to be extended to each counterparty and evaluates the appropriateness of unsecured credit limits on an ongoing basis. To further mitigate wholesale counterparty credit risk, PacifiCorp enters into netting and collateral arrangements that may include margining and cross-product netting agreements and obtains third‑party guarantees, letters of credit and cash deposits. If required, PacifiCorp exercises rights under these arrangements, including calling on the counterparty's credit support arrangement. Collateral and Contingent Features In accordance with industry practice, certain wholesale agreements, including derivative contracts, contain credit support provisions that in part base certain collateral requirements on credit ratings for senior unsecured debt as reported by one or more of the recognized credit rating agencies. These agreements may provide bilateral rights to demand cash or other security if credit exposures on a net basis exceed specified rating-dependent threshold levels ("credit-risk-related contingent features"). These agreements and other agreements that do not refer to specified rating-dependent thresholds may provide the right for counterparties to demand "adequate assurance" if there is a material adverse change in PacifiCorp's creditworthiness. These rights can vary by contract and by counterparty. As of June 30, 2024, PacifiCorp's issuer credit ratings for its senior secured debt and its issuer credit ratings for senior unsecured debt from the recognized credit rating agencies were investment grade. The aggregate fair value of PacifiCorp's derivative contracts in liability positions with objective credit-risk-related contingent features totaled $159 million and $108 million as of June 30, 2024 and December 31, 2023, respectively, for which PacifiCorp had posted collateral of $48 million and $12 million, respectively, in the form of cash deposits. If all credit-risk-related contingent features for derivative contracts in liability positions had been triggered as of June 30, 2024 and December 31, 2023, PacifiCorp would have been required to post $90 million and $84 million, respectively, of additional collateral. PacifiCorp's collateral requirements could fluctuate considerably due to market price volatility, changes in credit ratings, changes in legislation or regulation or other factors.

The Company has various financial assets and liabilities that are measured at fair value on the Consolidated Financial Statements using inputs from the three levels of the fair value hierarchy. A financial asset or liability classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The three levels are as follows: • Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. • Level 2 — Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs). • Level 3 — Unobservable inputs reflect the Company's judgments about the assumptions market participants would use in pricing the asset or liability since limited market data exists. The Company develops these inputs based on the best information available, including its own data. The following table presents the Company's financial assets and liabilities recognized on the Consolidated Balance Sheets and measured at fair value on a recurring basis (in millions): Input Levels for Fair Value Measurements Level 1 Level 2 Level 3 Other (1) Total As of June 30, 2024: Assets: Commodity derivatives $ — $ 126 $ 7 $ (41) $ 92 Interest rate derivatives 39 46 12 — 97 Mortgage loans held for sale — 705 — — 705 Money market mutual funds 3,037 — — — 3,037 Debt securities: U.S. government obligations 1,844 — — — 1,844 Corporate obligations — 95 — — 95 Municipal obligations — 2 — — 2 Agency, asset and mortgage-backed obligations — 1 — — 1 Equity securities: U.S. companies 460 — — — 460 International companies 1,748 — — — 1,748 Investment funds 305 — — — 305 $ 7,433 $ 975 $ 19 $ (41) $ 8,386 Liabilities: Commodity derivatives $ (2) $ (202) $ (140) $ 96 $ (248) Foreign currency exchange rate derivatives — (13) — — (13) Interest rate derivatives — (3) (1) 2 (2) $ (2) $ (218) $ (141) $ 98 $ (263) Input Levels for Fair Value Measurements Level 1 Level 2 Level 3 Other (1) Total As of December 31, 2023: Assets: Commodity derivatives $ 1 $ 121 $ 4 $ (31) $ 95 Interest rate derivatives 38 40 7 — 85 Mortgage loans held for sale — 451 — — 451 Money market mutual funds 1,310 — — — 1,310 Debt securities: U.S. government obligations 1,253 — — — 1,253 Corporate obligations — 70 — — 70 Municipal obligations — 3 — — 3 Equity securities: U.S. companies 427 — — — 427 International companies 2,226 — — — 2,226 Investment funds 268 — — — 268 $ 5,523 $ 685 $ 11 $ (31) $ 6,188 Liabilities: Commodity derivatives $ (7) $ (134) $ (95) $ 54 $ (182) Foreign currency exchange rate derivatives — (8) — — (8) Interest rate derivatives — (7) — 4 (3) $ (7) $ (149) $ (95) $ 58 $ (193) (1) Represents netting under master netting arrangements and a net cash collateral receivable of $57 million and $27 million as of June 30, 2024 and December 31, 2023, respectively. Derivative contracts are recorded on the Consolidated Balance Sheets as either assets or liabilities and are stated at estimated fair value unless they are designated as normal purchases or normal sales and qualify for the exception afforded by GAAP. When available, the fair value of derivative contracts is estimated using unadjusted quoted prices for identical contracts in the market in which the Company transacts. When quoted prices for identical contracts are not available, the Company uses forward price curves. Forward price curves represent the Company's estimates of the prices at which a buyer or seller could contract today for delivery or settlement at future dates. The Company bases its forward price curves upon market price quotations, when available, or internally developed and commercial models, with internal and external fundamental data inputs. Market price quotations are obtained from independent brokers, exchanges, direct communication with market participants and actual transactions executed by the Company. Market price quotations are generally readily obtainable for the applicable term of the Company's outstanding derivative contracts; therefore, the Company's forward price curves reflect observable market quotes. Market price quotations for certain electricity and natural gas trading hubs are not as readily obtainable due to the length of the contract. Given that limited market data exists for these contracts, as well as for those contracts that are not actively traded, the Company uses forward price curves derived from internal models based on perceived pricing relationships to major trading hubs that are based on unobservable inputs. The estimated fair value of these derivative contracts is a function of the underlying forward commodity prices, interest rates, currency rates, related volatility, counterparty creditworthiness and duration of contracts. The Company's mortgage loans held for sale are valued based on independent quoted market prices, where available, or the prices of other mortgage whole loans with similar characteristics. As necessary, these prices are adjusted for typical securitization activities, including servicing value, portfolio composition, market conditions and liquidity. The Company's investments in money market mutual funds and debt and equity securities are stated at fair value. When available, a readily observable quoted market price or net asset value of an identical security in an active market is used to record the fair value. In the absence of a quoted market price or net asset value of an identical security, the fair value is determined using pricing models or net asset values based on observable market inputs and quoted market prices of securities with similar characteristics. The following table reconciles the beginning and ending balances of the Company's financial assets and liabilities measured at fair value on a recurring basis using significant Level 3 inputs (in millions). Transfers out of Level 3 occur primarily due to increased price observability.

The Company's long-term debt is carried at cost on the Consolidated Balance Sheets. The fair value of the Company's long-term debt is a Level 2 fair value measurement and has been estimated based upon quoted market prices, where available, or at the present value of future cash flows discounted at rates consistent with comparable maturities with similar credit risks. The carrying value of the Company's variable-rate long-term debt approximates fair value because of the frequent repricing of these instruments at market rates.

Derivative contracts are recorded on the Consolidated Balance Sheets as either assets or liabilities and are stated at estimated fair value unless they are designated as normal purchases or normal sales and qualify for the exception afforded by GAAP. A discounted cash flow valuation method was used to estimate fair value. When available, the fair value of derivative contracts is estimated using unadjusted quoted prices for identical contracts in the market in which PacifiCorp transacts. When quoted prices for identical contracts are not available, PacifiCorp uses forward price curves. Forward price curves represent PacifiCorp's estimates of the prices at which a buyer or seller could contract today for delivery or settlement at future dates.

Market price quotations are obtained from independent energy brokers, exchanges, direct communication with market participants and actual transactions executed by PacifiCorp. Market price quotations for certain major electricity and natural gas trading hubs are generally readily obtainable for the first three years; therefore, PacifiCorp's forward price curves for those locations and periods reflect observable market quotes. Market price quotations for other electricity and natural gas trading hubs are not as readily obtainable for the first three years. Given that limited market data exists for these contracts, as well as for those contracts that are not actively traded, PacifiCorp uses forward price curves derived from internal models based on perceived pricing relationships to major trading hubs that are based on unobservable inputs. The estimated fair value of these derivative contracts is a function of underlying forward commodity prices, interest rates, currency rates, related volatility, counterparty creditworthiness and duration of contracts. Refer to Note 9 for further discussion regarding PacifiCorp's risk management and hedging activities. PacifiCorp's investments in money market mutual funds and investment funds are stated at fair value. When available, PacifiCorp uses a readily observable quoted market price or net asset value of an identical security in an active market to record the fair value.

Given that limited market data exists for these contracts, as well as for those contracts that are not actively traded, Eastern Energy Gas uses forward price curves derived from internal models based on perceived pricing relationships to major trading hubs that are based on unobservable inputs. The estimated fair value of these derivative contracts is a function of underlying forward commodity prices, interest rates, currency rates, related volatility, counterparty creditworthiness and duration of contracts. Eastern Energy Gas' long-term debt is carried at cost on the Consolidated Financial Statements. The fair value of Eastern Energy Gas' long-term debt is a Level 2 fair value measurement and has been estimated based upon quoted market prices, where available, or at the present value of future cash flows discounted at rates consistent with comparable maturities with similar credit risks.

EGTS
Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items]
Fair Value Measurements	Fair Value Measurements The carrying value of EGTS' cash, certain cash equivalents, receivables, payables, accrued liabilities and short-term borrowings approximates fair value because of the short-term maturity of these instruments. EGTS has various financial assets and liabilities that are measured at fair value on the Consolidated Financial Statements using inputs from the three levels of the fair value hierarchy. A financial asset or liability classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The three levels are as follows: • Level 1 - Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that EGTS has the ability to access at the measurement date. • Level 2 - Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs). • Level 3 - Unobservable inputs reflect EGTS' judgments about the assumptions market participants would use in pricing the asset or liability since limited market data exists. EGTS develops these inputs based on the best information available, including its own data. The following table presents EGTS' financial assets and liabilities recognized on the Consolidated Balance Sheets and measured at fair value on a recurring basis (in millions): Input Levels for Fair Value Measurements Level 1 Level 2 Level 3 Total As of June 30, 2024: Assets: Money market mutual funds $ 34 $ — $ — $ 34 Equity securities: Investment funds 17 — — 17 $ 51 $ — $ — $ 51 As of December 31, 2023: Assets: Money market mutual funds $ 5 $ — $ — $ 5 Equity securities: Investment funds 19 — — 19 $ 24 $ — $ — $ 24 EGTS' investments in money market mutual funds and investment funds are stated at fair value. When available, a readily observable quoted market price or net asset value of an identical security in an active market is used to record the fair value. Derivative contracts are recorded on the Consolidated Balance Sheets as either assets or liabilities and are stated at estimated fair value unless they are designated as normal purchase or normal sales and qualify for the exception afforded by GAAP. When available, the fair value of derivative contracts is estimated using unadjusted quoted prices for identical contracts in the market in which EGTS transacts. When quoted prices for identical contracts are not available, EGTS uses forward price curves. Forward price curves represent EGTS' estimates of the prices at which a buyer or seller could contract today for delivery or settlement at future dates. EGTS bases its forward price curves upon market price quotations, when available, or internally developed and commercial models, with internal and external fundamental data inputs. Market price quotations are obtained from independent brokers, exchanges, direct communication with market participants and actual transactions executed by EGTS. Market price quotations are generally readily obtainable for the applicable term of EGTS' outstanding derivative contracts; therefore, EGTS' forward price curves reflect observable market quotes. Market price quotations for certain natural gas trading hubs are not as readily obtainable due to the length of the contracts. Given that limited market data exists for these contracts, as well as for those contracts that are not actively traded, EGTS uses forward price curves derived from internal models based on perceived pricing relationships to major trading hubs that are based on unobservable inputs.

Loss Contingencies [Line Items]
Commitments and Contingencies	Commitments and Contingencies Commitments The Company has the following firm commitments that are not reflected on the Consolidated Balance Sheets. Fuel Contracts During the six-month period ended June 30, 2024, PacifiCorp entered into certain coal supply and transportation agreements totaling $1.9 billion through 2030. During the six-month period ended June 30, 2024, MidAmerican Energy entered into firm construction commitments totaling $150 million for the remainder of 2024 through 2025 related to the construction and repowering of wind-powered generating facilities in Iowa. During the six-month period ended June 30, 2024, the Nevada Utilities entered into engineering, procurement and construction agreements along with equipment and materials agreements totaling $2.1 billion through 2028 for the Greenlink Nevada transmission expansion program that will be developed in western and northern Nevada. During the six-month period ended June 30, 2024, Sierra Pacific entered into engineering, procurement and construction agreements along with equipment and materials agreements totaling $986 million for a 400-MW solar photovoltaic facility with an additional 400-MW of co-located battery storage that will be developed in Churchill County, Nevada. Environmental Laws and Regulations The Company is subject to federal, state, local and foreign laws and regulations regarding air quality, climate change, emissions performance standards, water quality, coal ash disposal, hazardous and other environmental matters that have the potential to impact the Company's current and future operations. The Company believes it is in material compliance with all applicable laws and regulations. Lower Klamath Hydroelectric Project In November 2022, the Federal Energy Regulatory Commission ("FERC") issued a license surrender order for the Lower Klamath Project, which was accepted by the Klamath River Renewal Corporation ("KRRC") and the states of Oregon and California ("States") in December 2022, along with the transfer of the Lower Klamath Project dams. Although PacifiCorp no longer owned the Lower Klamath Project, PacifiCorp continued to operate the facilities under an operation and maintenance agreement with the KRRC until each facility was ready for removal. PacifiCorp's obligations under the operations and maintenance agreement terminated in January 2024. Removal of the Copco No. 2 facility was completed in November 2023, and removal of the remaining three dams (J.C. Boyle, Copco No. 1 and Iron Gate) began in January 2024 and is anticipated to be completed in late 2024. The KRRC has $450 million in funding available for dam removal and restoration; $200 million collected from PacifiCorp's Oregon and California customers and $250 million in California bond funds. PacifiCorp and the States have also agreed to equally share cost overruns that may occur above the initial $450 million in funding. Specifically, PacifiCorp and the States have agreed to equally fund an initial $45 million contingency fund and equally share any additional costs above that amount to ensure dam removal and restoration is complete. In May 2024, the KRRC communicated to PacifiCorp and the States that it expects to require the $45 million of contingency funds. Legal Matters The Company is party to a variety of legal actions, including litigation, arising out of the normal course of business, some of which assert claims for damages in substantial amounts and are described below. For certain legal actions, parties at times may seek to impose fines, penalties and other costs. Pursuant to ASC 450, " Contingencies ," a provision for a loss contingency is recorded when it is probable a liability is likely to occur and the amount of loss can be reasonably estimated. The Company evaluates the related range of reasonably estimated losses and records a loss based on its best estimate within that range or the lower end of the range if there is no better estimate. Wildfires As of the date of this filing, a significant number of complaints and demands alleging similar claims related to the Wildfires have been filed in Oregon and California, including a class action complaint in Oregon associated with 2020 Wildfires for which certain jury verdicts were issued as described below. The plaintiffs seek damages for economic losses, noneconomic losses, including mental suffering, emotional distress, personal injury and loss of life, punitive damages, other damages and attorneys' fees. Several insurance carriers have filed subrogation complaints in Oregon and California with allegations similar to those made in the aforementioned complaints. Additionally, the U.S. and Oregon Departments of Justice have informed PacifiCorp that they are contemplating filing actions against PacifiCorp in connection with certain of the Oregon 2020 Wildfires. PacifiCorp is actively cooperating with the U.S. and Oregon Departments of Justice on resolving these alleged claims through alternative dispute resolution. As of June 30, 2024, amounts sought in outstanding complaints and demands filed in Oregon and in certain demands made in California totaled approximately $3 billion, excluding any doubling or trebling of damages included in the complaints and the mass complaints described below that seek $43 billion. Generally, the complaints filed in California do not specify damages sought and are excluded from this amount. For class actions, amounts specified by the plaintiffs in the complaints include amounts based on estimates of the potential class size, which ultimately may be significantly greater than estimated. Additionally, damages are not limited to the amounts specified in the initially filed complaints as plaintiffs are frequently allowed to amend their complaints to add additional damages and amounts awarded in a court proceeding may be significantly greater than the damages specified. Oregon law provides for doubling of economic and property damages in the event the defendant is found to have acted with gross negligence, recklessness, willfulness or malice. Oregon law provides for trebling of the damages associated with timber, shrubs and produce in the event the defendant is determined to have willfully and intentionally trespassed. In California, under inverse condemnation, courts have held that investor-owned utilities can be liable for real and personal property damages from wildfires without the utility being found negligent and regardless of fault. California law also permits inverse condemnation plaintiffs to recover reasonable attorney fees and costs. In both Oregon and California, PacifiCorp has equipment in areas accessed through special use permits, easements or similar agreements that may contain provisions requiring it to pay for damages caused by its equipment regardless of fault. Even if inverse condemnation or other provisions do not apply, PacifiCorp could be found liable for all damages. Based on available information to date, PacifiCorp believes it is probable that losses will be incurred associated with the Wildfires. Final determinations of liability will only be made following the completion of comprehensive investigations, litigation or similar processes, the outcome of which, if adverse, could, in the aggregate, have a material adverse effect on PacifiCorp's financial condition. 2020 Wildfires In September 2020, a severe weather event resulting in high winds, low humidity and warm temperatures contributed to several major wildfires, which resulted in real and personal property and natural resource damage, personal injuries and loss of life and widespread power outages in Oregon and Northern California. The wildfires spread across certain parts of PacifiCorp's service territory and surrounding areas across multiple counties in Oregon and California, including Siskiyou County, California; Jackson County, Oregon; Douglas County, Oregon; Marion County, Oregon; Lincoln County, Oregon; and Klamath County, Oregon, burning over 500,000 acres in aggregate. Third-party reports for these wildfires indicate over 2,000 structures destroyed, including residences; several structures damaged; multiple individuals injured; and several fatalities. Investigations into the cause and origin of each wildfire are complex and ongoing and have been or are being conducted by various entities, including the U.S. Forest Service, the California Public Utilities Commission, the Oregon Department of Forestry, the Oregon Department of Justice, PacifiCorp and various experts engaged by PacifiCorp. The James Case On September 30, 2020, a class action complaint against PacifiCorp was filed, captioned Jeanyne James et al. v. PacifiCorp et al., (" James ") in Oregon Circuit Court in Multnomah County, Oregon ("Multnomah County Circuit Court Oregon"). The complaint was filed by Oregon residents and businesses who seek to represent a class of all Oregon citizens and entities whose real or personal property was harmed beginning on September 7, 2020, by wildfires in Oregon allegedly caused by PacifiCorp. In November 2021, the plaintiffs filed an amended complaint to limit the class to include Oregon citizens allegedly impacted by the Santiam Canyon, Echo Mountain Complex, South Obenchain and 242 wildfires. In May 2022, the Multnomah County Circuit Court Oregon granted issue class certification and consolidated the James case with several other cases. While PacifiCorp's pre-trial request for immediate appeal of the class certification was denied, it subsequently filed to appeal the class issues as described below. In April 2023, the jury trial for James with respect to 17 named plaintiffs began in Multnomah County Circuit Court Oregon. In June 2023, the jury issued its verdict finding PacifiCorp liable to the 17 named plaintiffs and to the class with respect to the four wildfires. The jury found PacifiCorp's conduct grossly negligent, reckless and willful as to each plaintiff and the entire class. The jury awarded the 17 named plaintiffs $90 million of damages, including $4 million of economic damages, $68 million of noneconomic damages and $18 million of punitive damages based on a 0.25 multiplier of the economic and noneconomic damages. In September 2023, the Multnomah County Circuit Court Oregon ordered trial dates for three damages phase trials described below wherein plaintiffs in each of the three damages phase trials would present evidence regarding their damages. In January 2024, the Multnomah County Circuit Court Oregon entered a limited judgment and money award for the June 2023 James verdict. The limited judgment awards $92 million of damages based on the amounts awarded by the jury, as well as doubling of the economic damages and offsetting of any insurance proceeds received by plaintiffs. The limited judgment created a lien against PacifiCorp, attaching a debt for the money awards. PacifiCorp posted a supersedeas bond, which stays any effort to seek payment of the judgment pending final resolution of any appeals. Under Oregon Revised Statutes 82.010, interest at a rate of 9% per annum will accrue on the judgment commencing at the date the judgment was entered until the entire money award is paid, amended or reversed by an appellate court. In January 2024, PacifiCorp filed a notice of appeal associated with the June 2023 verdict in James , including whether the case can proceed as a class action and filed a motion to stay further damages phase trials. On February 14, 2024, the Oregon Court of Appeals denied PacifiCorp's request to stay the damages phase trials. On February 13, 2024, the 17 named plaintiffs filed a notice of cross-appeal as to the January 2024 limited judgment and money award. The appeals process and further actions could take several years. In January 2024, the jury for the first James damages phase trial awarded nine plaintiffs $62 million of damages, including $6 million of economic damages and $56 million of noneconomic damages. After the jury verdict, the Multnomah County Circuit Court Oregon doubled the economic damages to $12 million and added $16 million of punitive damages using the 0.25 multiplier determined by the jury for the June 2023 James verdict bringing the total damages awarded to $84 million. PacifiCorp requested that the Multnomah County Circuit Court Oregon judge offset the damage awards by deducting insurance proceeds received by any of the nine plaintiffs, and on March 25, 2024, the Multnomah County Circuit Court Oregon granted in large part the offset request. In April 2024, the Multnomah County Circuit Court Oregon entered a limited judgment and money award for the January 2024 James verdict. The limited judgment awards $80 million of damages based on the amounts awarded by the jury and offsetting insurance proceeds received by plaintiffs. The limited judgment created a lien against PacifiCorp, attaching a debt for the money awards. In April 2024, PacifiCorp posted a supersedeas bond, which stays any effort to seek payment of the judgment pending final resolution of any appeals. PacifiCorp amended its January 2024 appeal of the June 2023 James verdict to include the January 2024 jury verdict. In March 2024, the jury for the second James damages phase trial awarded ten plaintiffs $42 million of damages, including $12 million of doubled economic damages, $23 million of noneconomic damages and $7 million of punitive damages using the 0.25 multiplier determined by the jury for the June 2023 James verdict. PacifiCorp requested that the Multnomah County Circuit Court Oregon judge offset the damage awards by deducting insurance proceeds received by any of the ten plaintiffs and on May 6, 2024, the Multnomah County Circuit Court Oregon granted the offset request. In June 2024, the Multnomah County Circuit Court Oregon entered a limited judgment and money award for the March 2024 James verdict. The limited judgment awards $38 million of damages based on the amounts awarded by the jury and offsetting insurance proceeds received by plaintiffs. The limited judgment created a lien against PacifiCorp, attaching a debt for the money awards. In July 2024, PacifiCorp posted a supersedeas bond, which stays any effort to seek payment of the judgment pending final resolution of any appeals. PacifiCorp further amended its appeal of the June 2023 James verdict to include the March 2024 jury verdict. In March 2024, settlement was reached with five commercial timber plaintiffs in the James consolidated cases, and the jury trial scheduled for April 2024 was cancelled. In April, May and July 2024, four separate mass complaints against PacifiCorp naming 1,443 individual class members were filed in Multnomah County Circuit Court Oregon referencing James as the lead case. These James mass complaints make damages only allegations seeking economic, noneconomic and punitive damages, as well as doubling of economic damages. PacifiCorp believes the magnitude of damages sought by the class members in the James mass complaints to be of remote likelihood of being awarded based on the amounts awarded in the jury verdicts described above that are being appealed. 2022 McKinney Fire According to the California Department of Forestry and Fire Protection, a wildfire began on July 29, 2022, in the Oak Knoll Ranger District of the Klamath National Forest in Siskiyou County, California located in PacifiCorp's service territory, burning over 60,000 acres. Third-party reports indicate that the 2022 McKinney Fire resulted in 11 structures damaged; 185 structures destroyed, including residences; 12 injuries; and four fatalities. The cause of the 2022 McKinney Fire is undetermined and remains under investigation by the U.S. Forest Service, the California Public Utilities Commission, PacifiCorp and various experts engaged by PacifiCorp. Estimated Losses for and Settlements Associated with the Wildfires Based on the facts and circumstances available to PacifiCorp as of the date of this filing, including (i) ongoing cause and origin investigations; (ii) ongoing settlement and mediation discussions; (iii) other litigation matters and upcoming legal proceedings; and (iv) the status of the James case, PacifiCorp recorded cumulative estimated probable losses associated with the Wildfires of $2,658 million through June 30, 2024. PacifiCorp's cumulative accrual includes estimates of probable losses for fire suppression costs, real and personal property damages, natural resource damages and noneconomic damages such as personal injury damages and loss of life damages that it is reasonably able to estimate at this time and which is subject to change as additional relevant information becomes available. Through June 30, 2024, PacifiCorp paid $775 million in settlements associated with the 2020 Wildfires and paid an additional $246 million subsequent to June 30, 2024, for the Wildfires. To date, PacifiCorp has reached additional settlements associated with the Wildfires totaling $199 million that have yet to be paid. As a result of the settlements, various trials have been cancelled. The following table presents changes in PacifiCorp's liability for estimated losses associated with the Wildfires (in millions): Three-Month Periods Six-Month Periods Ended June 30, Ended June 30, 2024 2023 2024 2023 Beginning balance $ 1,705 $ 824 $ 1,723 $ 424 Accrued losses 251 141 251 541 Payments (73) (17) (91) (17) Ending balance $ 1,883 $ 948 $ 1,883 $ 948 As of June 30, 2024 and December 31, 2023, $445 million and $4 million of PacifiCorp's liability for estimated losses associated with the Wildfires is classified as a current liability captioned Wildfires liabilities on the Consolidated Balance Sheets. The amounts reflected as current as of June 30, 2024 reflect amounts reasonably expected to be paid out within the next year based on settlements reached as well as ongoing settlement and mediation efforts. The remainder of PacifiCorp's liability for estimated losses associated with the Wildfires as of June 30, 2024 and December 31, 2023 is classified as a noncurrent liability captioned Wildfires liabilities on the Consolidated Balance Sheets. The following table presents changes in PacifiCorp's receivable for expected insurance recoveries associated with the Wildfires (in millions): Three-Month Periods Six-Month Periods Ended June 30, Ended June 30, 2024 2023 2024 2023 Beginning balance $ 149 $ 287 $ 499 $ 246 Accruals — 92 — 133 Payments received (10) — (360) — Ending balance $ 139 $ 379 $ 139 $ 379 As of June 30, 2024, $15 million of PacifiCorp's receivable for expected insurance recoveries was included in Other receivables, net while the remaining $124 million was included in Other assets on the Consolidated Balance Sheets. As of December 31, 2023, $350 million of PacifiCorp's receivable for expected insurance recoveries was included in Other receivables, net while the remaining $149 million was included in Other assets on the Consolidated Balance Sheets. Insurance proceeds received to date relate to the 2020 Wildfires. During the three-month period ended June 30, 2024 and 2023, PacifiCorp recognized probable losses net of expected insurance recoveries associated with the Wildfires of $251 million and $49 million, respectively. During the six-month periods ended June 30, 2024 and 2023, PacifiCorp recognized probable losses net of expected insurance recoveries associated with the Wildfires of $251 million and $408 million, respectively. No additional insurance recoveries beyond those accrued and received to date are expected to be available. It is reasonably possible PacifiCorp will incur material additional losses beyond the amounts accrued for the Wildfires that could have a material adverse effect on PacifiCorp's financial condition. PacifiCorp is currently unable to reasonably estimate a specific range of possible additional losses that could be incurred due to the number of properties and parties involved, including claimants in the class to the James case, the variation in the types of properties and damages and the ultimate outcome of legal actions. HomeServices Antitrust Cases HomeServices is currently defending against several antitrust cases, all in federal district courts. In each case, plaintiffs claim HomeServices and certain of its subsidiaries (in one instance, HomeServices and BHE) conspired with co-defendants to artificially inflate real estate commissions by following and enforcing multiple listing service ("MLS") rules that require listing agents to offer a commission split to cooperating agents in order for the property to appear on the MLS ("Cooperative Compensation Rule"). None of the complaints specify damages sought. However, two cases allege Texas state law deceptive trade practices claims, for which plaintiffs have provided written notice of the damages sought totaling approximately $9 billion by separate notice as required by Texas law. In April 2019, the Burnett (formerly Sitzer) et al. v. HomeServices of America, Inc. et al. complaint was filed in the U.S. District Court for the Western District of Missouri (the "Burnett case"). This lawsuit, which was certified as a class in April 2022, was originally brought on behalf of named plaintiffs Joshua Sitzer and Amy Winger against the National Association of Realtors ("NAR"), Anywhere Real Estate, HomeServices of America, Inc., RE/MAX, LLC, and Keller Williams Realty, Inc. HSF Affiliates, LLC and BHH Affiliates, LLC, each a subsidiary of HomeServices, were subsequently added as defendants. Rhonda Burnett became a lead class plaintiff in June 2021. The jury trial commenced on October 16, 2023, and the jury returned a verdict for the plaintiffs on October 31, 2023, finding that the named defendants participated in a conspiracy to follow and enforce the Cooperative Compensation Rule, which conspiracy had the purpose or effect of raising, inflating, or stabilizing broker commission rates paid by home sellers. The jury further found that the class plaintiffs had proved damages in the amount of $1.8 billion. Joint and several liability applies for the co-defendants. Federal law authorizes trebling of damages and the award of pre-judgment interest and attorney fees. Prior to the trial, Anywhere Real Estate and RE/MAX, LLC reached settlement agreements with the plaintiffs. Subsequent to the trial, settlements were reached by Keller Williams and NAR on February 1, 2024 and March 15, 2024, respectively. The Anywhere Real Estate, RE/MAX, LLC and Keller Williams settlements received court approval on May 9, 2024, which has been appealed to the U.S. Court of Appeals for the Eighth Circuit. The NAR settlement is subject to court approval, which is scheduled for November 26, 2024. Final judgment has not yet been entered by the U.S. District Court for the Western District of Missouri. In April 2024, HomeServices agreed to terms with the plaintiffs to settle all claims asserted against HomeServices, HSF Affiliates, LLC and BHH Affiliates, LLC in the Burnett case as part of a proposed nationwide class settlement. The final settlement agreement, which includes scheduled payments over the next four years aggregating $250 million, has yet to be filed with the court and is ultimately subject to court approval. HomeServices recognized an after-tax charge of approximately $140 million during the three-month period ended March 31, 2024. If the settlement is not approved by the court, HomeServices intends to vigorously appeal on multiple grounds the jury's findings and damage award in the Burnett case, including whether the case can proceed as a class action. The appeals process and further actions could take several years. Guarantees The Company has entered into guarantees as part of the normal course of business and the sale or transfer of certain assets. These guarantees are not expected to have a material impact on the Company's consolidated financial results.

Third-party reports for these wildfires indicate over 2,000 structures destroyed, including residences; several structures damaged; multiple individuals injured; and several fatalities. Investigations into the cause and origin of each wildfire are complex and ongoing and have been or are being conducted by various entities, including the U.S. Forest Service, the California Public Utilities Commission, the Oregon Department of Forestry, the Oregon Department of Justice, PacifiCorp and various experts engaged by PacifiCorp. The James Case On September 30, 2020, a class action complaint against PacifiCorp was filed, captioned Jeanyne James et al. v. PacifiCorp et al., (" James ") in Oregon Circuit Court in Multnomah County, Oregon ("Multnomah County Circuit Court Oregon"). The complaint was filed by Oregon residents and businesses who seek to represent a class of all Oregon citizens and entities whose real or personal property was harmed beginning on September 7, 2020, by wildfires in Oregon allegedly caused by PacifiCorp. In November 2021, the plaintiffs filed an amended complaint to limit the class to include Oregon citizens allegedly impacted by the Santiam Canyon, Echo Mountain Complex, South Obenchain and 242 wildfires. In May 2022, the Multnomah County Circuit Court Oregon granted issue class certification and consolidated the James case with several other cases. While PacifiCorp's pre-trial request for immediate appeal of the class certification was denied, it subsequently filed to appeal the class issues as described below. In April 2023, the jury trial for James with respect to 17 named plaintiffs began in Multnomah County Circuit Court Oregon. In June 2023, the jury issued its verdict finding PacifiCorp liable to the 17 named plaintiffs and to the class with respect to the four wildfires. The jury found PacifiCorp's conduct grossly negligent, reckless and willful as to each plaintiff and the entire class. The jury awarded the 17 named plaintiffs $90 million of damages, including $4 million of economic damages, $68 million of noneconomic damages and $18 million of punitive damages based on a 0.25 multiplier of the economic and noneconomic damages. In September 2023, the Multnomah County Circuit Court Oregon ordered trial dates for three damages phase trials described below wherein plaintiffs in each of the three damages phase trials would present evidence regarding their damages. In January 2024, the Multnomah County Circuit Court Oregon entered a limited judgment and money award for the June 2023 James verdict. The limited judgment awards $92 million of damages based on the amounts awarded by the jury, as well as doubling of the economic damages and offsetting of any insurance proceeds received by plaintiffs. The limited judgment created a lien against PacifiCorp, attaching a debt for the money awards. PacifiCorp posted a supersedeas bond, which stays any effort to seek payment of the judgment pending final resolution of any appeals. Under Oregon Revised Statutes 82.010, interest at a rate of 9% per annum will accrue on the judgment commencing at the date the judgment was entered until the entire money award is paid, amended or reversed by an appellate court. In January 2024, PacifiCorp filed a notice of appeal associated with the June 2023 verdict in James , including whether the case can proceed as a class action and filed a motion to stay further damages phase trials. On February 14, 2024, the Oregon Court of Appeals denied PacifiCorp's request to stay the damages phase trials. On February 13, 2024, the 17 named plaintiffs filed a notice of cross-appeal as to the January 2024 limited judgment and money award. The appeals process and further actions could take several years. In January 2024, the jury for the first James damages phase trial awarded nine plaintiffs $62 million of damages, including $6 million of economic damages and $56 million of noneconomic damages. After the jury verdict, the Multnomah County Circuit Court Oregon doubled the economic damages to $12 million and added $16 million of punitive damages using the 0.25 multiplier determined by the jury for the June 2023 James verdict bringing the total damages awarded to $84 million. PacifiCorp requested that the Multnomah County Circuit Court Oregon judge offset the damage awards by deducting insurance proceeds received by any of the nine plaintiffs, and on March 25, 2024, the Multnomah County Circuit Court Oregon granted in large part the offset request. In April 2024, the Multnomah County Circuit Court Oregon entered a limited judgment and money award for the January 2024 James verdict. The limited judgment awards $80 million of damages based on the amounts awarded by the jury and offsetting insurance proceeds received by plaintiffs. The limited judgment created a lien against PacifiCorp, attaching a debt for the money awards. In April 2024, PacifiCorp posted a supersedeas bond, which stays any effort to seek payment of the judgment pending final resolution of any appeals. PacifiCorp amended its January 2024 appeal of the June 2023 James verdict to include the January 2024 jury verdict. In March 2024, the jury for the second James damages phase trial awarded ten plaintiffs $42 million of damages, including $12 million of doubled economic damages, $23 million of noneconomic damages and $7 million of punitive damages using the 0.25 multiplier determined by the jury for the June 2023 James verdict. PacifiCorp requested that the Multnomah County Circuit Court Oregon judge offset the damage awards by deducting insurance proceeds received by any of the ten plaintiffs and on May 6, 2024, the Multnomah County Circuit Court Oregon granted the offset request. In June 2024, the Multnomah County Circuit Court Oregon entered a limited judgment and money award for the March 2024 James verdict. The limited judgment awards $38 million of damages based on the amounts awarded by the jury and offsetting insurance proceeds received by plaintiffs. The limited judgment created a lien against PacifiCorp, attaching a debt for the money awards. In July 2024, PacifiCorp posted a supersedeas bond, which stays any effort to seek payment of the judgment pending final resolution of any appeals. PacifiCorp further amended its appeal of the June 2023 James verdict to include the March 2024 jury verdict. In March 2024, settlement was reached with five commercial timber plaintiffs in the James consolidated cases, and the jury trial scheduled for April 2024 was cancelled. In April, May and July 2024, four separate mass complaints against PacifiCorp naming 1,443 individual class members were filed in Multnomah County Circuit Court Oregon referencing James as the lead case. These James mass complaints make damages only allegations seeking economic, noneconomic and punitive damages, as well as doubling of economic damages. PacifiCorp believes the magnitude of damages sought by the class members in the James mass complaints to be of remote likelihood of being awarded based on the amounts awarded in the jury verdicts described above that are being appealed. 2022 McKinney Fire According to the California Department of Forestry and Fire Protection, a wildfire began on July 29, 2022, in the Oak Knoll Ranger District of the Klamath National Forest in Siskiyou County, California located in PacifiCorp's service territory, burning over 60,000 acres. Third-party reports indicate that the 2022 McKinney Fire resulted in 11 structures damaged; 185 structures destroyed, including residences; 12 injuries; and four fatalities. The cause of the 2022 McKinney Fire is undetermined and remains under investigation by the U.S. Forest Service, the California Public Utilities Commission, PacifiCorp and various experts engaged by PacifiCorp. Estimated Losses for and Settlements Associated with the Wildfires Based on the facts and circumstances available to PacifiCorp as of the date of this filing, including (i) ongoing cause and origin investigations; (ii) ongoing settlement and mediation discussions; (iii) other litigation matters and upcoming legal proceedings; and (iv) the status of the James case, PacifiCorp recorded cumulative estimated probable losses associated with the Wildfires of $2,658 million through June 30, 2024. PacifiCorp's cumulative accrual includes estimates of probable losses for fire suppression costs, real and personal property damages, natural resource damages and noneconomic damages such as personal injury damages and loss of life damages that it is reasonably able to estimate at this time and which is subject to change as additional relevant information becomes available. Through June 30, 2024, PacifiCorp paid $775 million in settlements associated with the 2020 Wildfires and paid an additional $246 million subsequent to June 30, 2024, for the Wildfires. To date, PacifiCorp has reached additional settlements associated with the Wildfires totaling $199 million that have yet to be paid. As a result of the settlements, various trials have been cancelled. The following table presents changes in PacifiCorp's liability for estimated losses associated with the Wildfires (in millions): Three-Month Periods Six-Month Periods Ended June 30, Ended June 30, 2024 2023 2024 2023 Beginning balance $ 1,705 $ 824 $ 1,723 $ 424 Accrued losses 251 141 251 541 Payments (73) (17) (91) (17) Ending balance $ 1,883 $ 948 $ 1,883 $ 948 As of June 30, 2024 and December 31, 2023, $445 million and $4 million of PacifiCorp's liability for estimated losses associated with the Wildfires is classified as a current liability captioned Wildfires liabilities on the Consolidated Balance Sheets. The amounts reflected as current as of June 30, 2024 reflect amounts reasonably expected to be paid out within the next year based on settlements reached as well as ongoing settlement and mediation efforts. The remainder of PacifiCorp's liability for estimated losses associated with the Wildfires as of June 30, 2024 and December 31, 2023 is classified as a noncurrent liability captioned Wildfires liabilities on the Consolidated Balance Sheets. The following table presents changes in PacifiCorp's receivable for expected insurance recoveries associated with the Wildfires (in millions): Three-Month Periods Six-Month Periods Ended June 30, Ended June 30, 2024 2023 2024 2023 Beginning balance $ 149 $ 287 $ 499 $ 246 Accruals — 92 — 133 Payments received (10) — (360) — Ending balance $ 139 $ 379 $ 139 $ 379 As of June 30, 2024, $15 million of PacifiCorp's receivable for expected insurance recoveries was included in Other receivables, net while the remaining $124 million was included in Other assets on the Consolidated Balance Sheets. As of December 31, 2023, $350 million of PacifiCorp's receivable for expected insurance recoveries was included in Other receivables, net while the remaining $149 million was included in Other assets on the Consolidated Balance Sheets. Insurance proceeds received to date relate to the 2020 Wildfires. During the three-month periods ended June 30, 2024 and 2023, PacifiCorp recognized probable losses net of expected insurance recoveries associated with the Wildfires of $251 million and $49 million, respectively. During the six-month periods ended June 30, 2024 and 2023, PacifiCorp recognized probable losses net of expected insurance recoveries associated with the Wildfires of $251 million and $408 million, respectively. No additional insurance recoveries beyond those accrued and received to date are expected to be available. It is reasonably possible PacifiCorp will incur material additional losses beyond the amounts accrued for the Wildfires that could have a material adverse effect on PacifiCorp's financial condition. PacifiCorp is currently unable to reasonably estimate a specific range of possible additional losses that could be incurred due to the number of properties and parties involved, including claimants in the class to the James case, the variation in the types of properties and damages and the ultimate outcome of legal actions. Guarantees PacifiCorp has entered into guarantees as part of the normal course of business and the sale or transfer of certain assets. These guarantees are not expected to have a material impact on PacifiCorp's consolidated financial results.

Segment Reporting Information [Line Items]
Segment Information	Segment Information MidAmerican Energy has identified two reportable segments: regulated electric and regulated natural gas. The regulated electric segment derives most of its revenue from regulated retail sales of electricity to residential, commercial, and industrial customers and from wholesale sales. The regulated natural gas segment derives most of its revenue from regulated retail sales of natural gas to residential, commercial, and industrial customers and also obtains revenue by transporting natural gas owned by others through its distribution system. Pricing for regulated electric and natural gas sales are established separately by regulatory agencies; therefore, management also reviews each segment separately to make decisions regarding allocation of resources and evaluating performance. Common operating costs, interest income, interest expense and income tax expense are allocated to each segment based on certain factors, which primarily relate to the nature of the cost.

The results of operations for the three- and six-month periods ended June 30, 2024, are not necessarily indicative of the results to be expected for the full year.
Use of Estimates	The preparation of the unaudited Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the unaudited Consolidated Financial Statements and the reported amounts of revenue and expenses during the period. Actual results may differ from the estimates used in preparing the unaudited Consolidated Financial Statements.

Additionally, the standard requires enhanced disclosures of significant segment expenses and other segment items, as well as incremental qualitative disclosures on both an annual and interim basis. This guidance is effective for annual reporting periods beginning after December 15, 2023, and interim reporting periods after December 15, 2024. Early adoption is permitted and retrospective application is required for all periods presented. The Company is currently evaluating the impact of adopting this guidance on its Consolidated Financial Statements and disclosures included within Notes to Consolidated Financial Statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes Topic 740, "Income Tax—Improvements to Income Tax Disclosures" which requires enhanced disclosures, including specific categories and disaggregation of information in the effective tax rate reconciliation, disaggregated information related to income taxes paid, income or loss from continuing operations before income tax expense or benefit, and income tax expense or benefit from continuing operations. This guidance is effective for annual reporting periods beginning after December 15, 2024.

The Company is currently evaluating the impact of adopting this guidance on its Consolidated Financial Statements and disclosures included within Notes to Consolidated Financial Statements. In March 2024, the United States Securities and Exchange Commission adopted final rules requiring disclosure of certain climate-related information in registrations statements and Form 10-Ks. The final rules require a registrant to disclose, among other things: material climate-related risks; activities to mitigate or adapt to such risks; information about the registrant's board of directors' oversight of climate-related risks and management's role in managing material climate-related risks; and information on any climate-related targets or goals that are material to the registrant's business, results of operations, or financial condition. Further, to facilitate investors' assessment of certain climate-related risks, the final rules require disclosure of Scope 1 and/or Scope 2 greenhouse gas emissions when those emissions are material and disclosure of the financial statement effects of severe weather events and other natural conditions. The final rules include phased-in compliance periods for all registrants, with the compliance date dependent on the registrant's filer status and the content of the disclosure. On April 4, 2024, the United States Securities and Exchange Commission voluntarily stayed implementation of the final rules, pending the completion of judicial review of consolidated challenges by the Court of Appeals for the Eighth Circuit.

Basis of Accounting	The unaudited Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and the United States Securities and Exchange Commission's rules and regulations for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the disclosures required by GAAP for annual financial statements. Management believes the unaudited Financial Statements contain all adjustments (consisting only of normal recurring adjustments) considered necessary for the fair presentation of the unaudited Financial Statements as of June 30, 2024, and for the three- and six-month periods ended June 30, 2024 and 2023. The results of operations for the six-month period ended June 30, 2024, are not necessarily indicative of the results to be expected for the full year.
Use of Estimates	The preparation of the unaudited Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the unaudited Financial Statements and the reported amounts of revenue and expenses during the period. Actual results may differ from the estimates used in preparing the unaudited Financial Statements.
