NOTES TO THE FINANCIAL STATEMENTS (UNAUDITED)
General
These combined notes accompany and form an integral part of the separate interim consolidated financial statements of each of the two separate registrants: Consolidated Edison, Inc. and its subsidiaries (Con Edison) and Consolidated Edison Company of New York, Inc. and its subsidiaries (CECONY). CECONY is a subsidiary of Con Edison and as such its financial condition and results of operations and cash flows, which are presented separately in the CECONY consolidated financial statements, are also consolidated, along with those of Orange and Rockland Utilities, Inc. (O&R), Con Edison Clean Energy Businesses, Inc. (together with its subsidiaries, the Clean Energy Businesses) and Con Edison Transmission, Inc. (together with its subsidiaries, Con Edison Transmission) in Con Edison’s consolidated financial statements. The term “Utilities” is used in these notes to refer to CECONY and O&R.
As used in these notes, the term “Companies” refers to Con Edison and CECONY and, except as otherwise noted, the information in these combined notes relates to each of the Companies. However, CECONY makes no representation as to information relating to Con Edison or the subsidiaries of Con Edison other than itself.
The separate interim consolidated financial statements of each of the Companies are unaudited but, in the opinion of their respective managements, reflect all adjustments (which include only normally recurring adjustments) necessary for a fair statement of the results for the interim periods presented. The Companies’ separate interim consolidated financial statements should be read together with their separate audited financial statements (including the combined notes thereto) included in Item 8 of their combined Annual Report on Form 10-K for the year ended December 31, 2019 and their separate unaudited financial statements (including the combined notes thereto) included in Part 1, Item 1 of their combined Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2020. Certain prior period amounts have been reclassified to conform to the current period presentation.
Con Edison has two regulated utility subsidiaries: CECONY and O&R. CECONY provides electric service and gas service in New York City and Westchester County. The company also provides steam service in parts of Manhattan. O&R, along with its regulated utility subsidiary, provides electric service in southeastern New York and northern New Jersey and gas service in southeastern New York. Con Edison Clean Energy Businesses, Inc., through its subsidiaries, develops, owns and operates renewable and energy infrastructure projects and provides energy-related products and services to wholesale and retail customers. Con Edison Transmission, Inc. invests in electric transmission facilities through its subsidiary, Consolidated Edison Transmission, LLC (CET Electric), and invests in gas pipeline and storage facilities through its subsidiary Con Edison Gas Pipeline and Storage, LLC (CET Gas).
Note A – Summary of Significant Accounting Policies and Other Matters
Financial Instruments – Credit Losses
Adoption of New Standard
In January 2020, the Companies adopted Accounting Standards Update (ASU) 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (CECL). The amendments replace the incurred loss impairment methodology which involved delayed recognition of credit losses. The amendments introduce an expected credit loss impairment model which requires immediate recognition of anticipated losses over the instrument’s life. A broader range of reasonable and supportable information must be considered in developing the credit loss estimates. The Companies' financial instruments subject to the amendments are included in the lines “Accounts receivable – customers” and “Other receivables.” Substantially all of these in-scope financial instruments are expected to be collected within one year of billing.
The Companies adopted the amendments using the modified retrospective method for all financial instruments measured at amortized costs. Results for reporting periods beginning after January 1, 2020 are presented under Accounting Standards Codification (ASC) 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. No prior period adjustment or charge to retained earnings for cumulative impact was required as a result of the Companies’ adoption of the amendments.
The Utilities’ “Account receivable – customers” balance consists of utility bills due (bills are generally due the month following billing) from customers who have energy delivered, generated, or services provided by the Utilities. The balance also reflects the Utilities’ purchase of receivables from energy service companies to support the retail choice programs.
“Other receivables” balance generally reflects costs billed by the Utilities for goods and services provided to external parties, such as accommodation work for private parties and certain governmental entities, real estate rental and
19

pole attachments. The Clean Energy Businesses’ other receivables balance includes bills related to the sale of energy from renewable electric production projects.
The Clean Energy Businesses’ customer accounts receivable balance generally reflects the management of energy supply assets, energy-efficiency services to government and commercial customers, and the engineering, procurement, and construction services of renewable energy projects. The Clean Energy Businesses calculate an allowance for uncollectible accounts related to their energy services customers based on an aging and customer-specific analysis. The amount of such reserves was not material at June 30, 2020.
The Companies develop expected loss estimates using past events data and consider current conditions and future reasonable and supportable forecasts. Changes to the Utilities’ reserve balances that result in write-offs of customer accounts receivable balances above existing rate allowances are not reflected in rates during the term of the current rate plans. For the Utilities’ customer accounts receivable allowance for uncollectible accounts, past events considered include write-offs relative to customer accounts receivable; current conditions include macro-and micro-economic conditions related to trends in the local economy and bankruptcy rates and aged customer accounts receivable balances, among other factors; and forecasts about the future include assumptions related to the level of write-offs and recoveries.
Other receivables allowance for uncollectible accounts is calculated based on a historical average of collections relative to total other receivables, including current receivables. Current macro- and micro-economic conditions are also considered when calculating the current reserve. Probable outcomes of pending litigation, whether favorable or unfavorable to the Companies, are also included in the consideration.
During the first six months of 2020, the potential economic impact of the COVID-19 pandemic was also considered in forward-looking projections related to write-off and recovery rates and resulted in increases to the allowance for uncollectible accounts. The increases to the allowance for uncollectible accounts for Con Edison and CECONY were $12 million and $11 million, respectively, for the three months ended June 30, 2020 and $18 million and $16 million, respectively, for the six months ended June 30, 2020.
Customer accounts receivable and the associated allowance for uncollectible accounts are included in the line “Accounts receivable – customers” on the Companies’ consolidated balance sheets.

General Utility Plant
General utility plant of Con Edison and CECONY included $90 million and $85 million, respectively, at June 30, 2020 and $93 million and $88 million, respectively, at December 31, 2019, related to a May 2018 acquisition of software licenses. The estimated aggregate annual amortization expense related to the software licenses for Con Edison and CECONY is $7 million. The accumulated amortization for Con Edison and CECONY was $13 million at June 30, 2020 and $10 million at December 31, 2019.
Goodwill
The Companies test goodwill for impairment at least annually or whenever there is a triggering event, and test long-lived and intangible assets for recoverability when events or changes in circumstances indicate that the carrying value of long-lived or intangible assets may not be recoverable. The Companies identified no triggering events or changes in circumstances related to the COVID-19 pandemic that would indicate that the carrying value of long-lived or intangible assets may not be recoverable at June 30, 2020.
Long-Lived and Intangible Assets
In January 2019, Pacific Gas and Electric Company (PG&E) filed in the United States Bankruptcy Court for the Northern District of California for reorganization under Chapter 11 of the U.S. Bankruptcy Code. The output of certain of the Clean Energy Businesses' renewable electric production projects with an aggregate generating capacity of 680 MW (AC) (PG&E Projects) is sold to PG&E under long-term power purchase agreements (PG&E PPAs). Most of the PG&E PPAs have contract prices that are higher than estimated market prices.
In July 2020, PG&E’s plan of reorganization, previously confirmed by the bankruptcy court in June 2020, became effective. The California Public Utilities Commission also approved PG&E’s plan of reorganization and found that it complied with the wildfire fund legislation enacted by California in July 2019. The wildfire fund legislation includes provisions for the establishment of wildfire liquidity and insurance funds and possible limitation of future wildfire liabilities for California utilities. PG&E, Southern California Edison Company and San Diego Gas & Electric Company have agreed to participate in the insurance fund.
The PG&E bankruptcy was an event of default under the PG&E PPAs. Distributions from the related projects to the Clean Energy Businesses were restricted during the pendency of the bankruptcy. As of the effective date of the plan of reorganization, PG&E assumed all of the PG&E PPAs. In July 2020, the Clean Energy Businesses received previously restricted distributions and have resumed distributions for all projects. See “Reconciliation of Cash, Temporary Cash Investments and Restricted Cash,” below.
Also, as a result of PG&E assuming all of the PG&E PPAs and emerging from bankruptcy, the Clean Energy Businesses have received full payment of all past due receivables, and all related project debt with a maturity longer than one year has been reclassified to long-term debt.
Earnings Per Common Share
Con Edison presents basic and diluted earnings per share (EPS) on the face of its consolidated income statement. Basic EPS is calculated by dividing earnings available to common shareholders (“Net income for common stock” on Con Edison’s consolidated income statement) by the weighted average number of Con Edison common shares outstanding during the period. In the calculation of diluted EPS, weighted average shares outstanding are increased for additional shares that would be outstanding if potentially dilutive securities were converted to common stock.
21

Potentially dilutive securities for Con Edison consist of restricted stock units and deferred stock units for which the average market price of the common shares for the period was greater than the exercise price.
For the three and six months ended June 30, 2020 and 2019, basic and diluted EPS for Con Edison are calculated as follows:

| For the Three Months Ended June 30, | For the Six Months Ended June 30,
(Millions of Dollars, except per share amounts/Shares in Millions) | 2020 | 2019 | 2020 | 2019
Net income for common stock | $190 | $152 | $565 | $576
Weighted average common shares outstanding – basic | 334.1 | 328.3 | 333.8 | 325.2
Add: Incremental shares attributable to effect of potentially dilutive securities | 0.9 | 0.9 | 0.9 | 0.9
Adjusted weighted average common shares outstanding – diluted | 335.0 | 329.2 | 334.7 | 326.1
Net Income per common share – basic | $0.57 | $0.46 | $1.69 | $1.77
Net Income per common share – diluted | $0.57 | $0.46 | $1.69 | $1.77

The computation of diluted EPS for the three and six months ended June 30, 2020 and 2019 excludes immaterial amounts of performance share awards that were not included because of their anti-dilutive effect.
Changes in Accumulated Other Comprehensive Income/(Loss) by Component
For the three and six months ended June 30, 2020 and 2019, changes to accumulated other comprehensive income/(loss) (OCI) for Con Edison and CECONY are as follows:

| For the Three Months Ended June 30,
| Con Edison | CECONY
(Millions of Dollars) | 2020 |  | 2019 | 2020 | 2019 |
Beginning balance, accumulated OCI, net of taxes (a) | $(14) | $(12) | $(5) | $(5)
Amounts reclassified from accumulated OCI related to pension plan liabilities, net of tax of $(1) for Con Edison in 2020 (a)(b) | — |  | 1 | 1 | — |
Current period OCI, net of taxes | — |  | 1 | 1 | — |
Ending balance, accumulated OCI, net of taxes | $(14) | $(11) | $(4) | $(5)

| For the Six Months Ended June 30,
| Con Edison | CECONY

Beginning balance, accumulated OCI, net of taxes (a) | $(19) | $(16) | $(6) | $(5)
OCI before reclassifications, net of tax of $(1) for Con Edison in 2020 and 2019 | 4 | 2 | — |  | — |
Amounts reclassified from accumulated OCI related to pension plan liabilities, net of tax of $(1) for Con Edison in 2020 and 2019 (a)(b) | 1 | 3 | 2 | — |
Current period OCI, net of taxes | 5 | 5 | 2 | — |
Ending balance, accumulated OCI, net of taxes | $(14) | $(11) | $(4) | $(5)

(a) | Tax reclassified from accumulated OCI is reported in the income tax expense line item of the consolidated income statement.

(b) | For the portion of unrecognized pension and other postretirement benefit costs relating to the Utilities, costs are recorded into, and amortized out of, regulatory assets and liabilities instead of OCI. The net actuarial losses and prior service costs recognized during the period are included in the computation of total periodic pension and other postretirement benefit cost. See Notes E and F.

Reconciliation of Cash, Temporary Cash Investments and Restricted Cash
Cash, temporary cash investments and restricted cash are presented on a combined basis in the Companies’ consolidated statements of cash flows. At June 30, 2020 and 2019, cash, temporary cash investments and restricted cash for Con Edison and CECONY were as follows:
22

| At June 30,
| Con Edison | CECONY
(Millions of Dollars) | 2020 | 2019 | 2020 |  | 2019 |
Cash and temporary cash investments | $1,144 | $831 | $1,096 | $786
Restricted cash (a) | 201 | 139 | — |  | — |
Total cash, temporary cash investments and restricted cash | $1,345 | $970 | $1,096 | $786

(a) | Restricted cash included cash of the Clean Energy Businesses' renewable electric production project subsidiaries ($192 million and $138 million at June 30, 2020 and 2019, respectively) that, under the related project debt agreements, is either restricted until the various maturity dates of the project debt to being used for normal operating expenses and capital expenditures, debt service, and required reserves or restricted as a result of the PG&E bankruptcy. During the pendency of the PG&E bankruptcy, cash was not distributed from the related projects to the Clean Energy Businesses. In July 2020, PG&E’s plan of reorganization became effective. In July 2020, the Clean Energy Businesses received previously restricted distributions and have resumed distributions for all projects. See “Long-Lived and Intangible Assets,” above, and Note C. At June 30, 2020, restricted cash included cash deposits held by the Clean Energy Businesses’ battery storage business ($9 million). At June 30, 2019, restricted cash included O&R's New Jersey utility subsidiary, Rockland Electric Company transition bond charge collections, net of principal, interest, trustee and service fees ($1 million).

Note B – Regulatory Matters
COVID-19 Regulatory Matters
Governors, public utility commissions, federal authorities and other regulatory agencies in the states in which the Utilities operate have issued orders related to the COVID-19 pandemic that impact the Utilities as described below.
New York State Regulation
In March 2020, New York State Governor Cuomo declared a State Disaster Emergency for the State of New York, due to the COVID-19 pandemic and signed the "New York State on PAUSE" executive order that closed all non-essential businesses statewide. New York State designated utilities, including CECONY and O&R, as essential businesses that were able to continue a portion of their work during the effectiveness of the PAUSE order. In May 2020, the "New York Forward" plan went into effect. New York Forward is a phased plan to reopen businesses in geographic areas of New York State that meet metrics established by various public health organizations. Since the emergency declaration, and due to economic conditions, the NYSPSC and the Utilities have mitigated the potential impact of the COVID-19 pandemic on the Utilities, their customers and other stakeholders.
In March 2020, the Utilities began suspending service disconnections, certain collection notices, final bill collection agency activity, new late payment charges and certain other fees for all customers. The Utilities also began providing payment extensions for all customers that were scheduled to be disconnected prior to the start of the COVID-19 pandemic. In June 2020, the state of New York enacted a law prohibiting New York utilities, including CECONY and O&R, from disconnecting residential customers during the COVID-19 state of emergency. In addition, such prohibition will apply for an additional 180 days after the state of emergency ends for residential customers who have experienced a change in financial circumstances due to the COVID-19 pandemic. The law expires on March 31, 2021. For the three and six months ended June 30, 2020, the estimated foregone revenues that were not collected by the Utilities were approximately $20 million and $23 million, respectively, for CECONY and $1.2 million and $1.4 million, respectively, for O&R. See Note K to the Second Quarter Financial Statements. Also in March 2020, the Utilities requested and the NYSPSC granted extensions to file their 2019 Earnings Adjustment Mechanisms (EAMs) reports, which were filed in July 2020. The earned EAM incentives of approximately $46 million and $3 million for CECONY and O&R, respectively, are expected to be recovered from customers over a twelve-month period beginning September 2020.
As of June 30, 2020, CECONY deferred, for New York City residential customers, $9 million of higher summer generation capacity supply costs. CECONY estimates that a total of $58 million of higher supply costs will be deferred and expects to recover such costs from November 2020 through April 2021. Also in June 2020, the NYSPSC directed CECONY to implement a summer cooling credit program to help mitigate the cost of staying home and running air conditioning for health-vulnerable low-income customers due to the limited availability of public cooling facilities as a result of the COVID-19 social distancing measures. The NYSPSC further ordered that the estimated $70.6 million cost of the program will be recovered over five years, beginning in January 2021.
In June 2020, the NYSPSC established a generic proceeding on the impacts of the COVID-19 pandemic and sought comment on a variety of COVID-19 related issues. In July 2020, the Utilities submitted joint comments
23

with other large utilities in New York State that included a formal request to defer all COVID-19 related costs and for a surcharge mechanism to collect such deferrals based upon the individual utility's need.
The Utilities’ rate plans have revenue decoupling mechanisms in their New York electric and gas businesses that reconcile actual energy delivery revenues to the authorized delivery revenues approved by the NYSPSC per month and accumulate the deferred balances semi-annually under CECONY's electric rate plan (January through June and July through December, respectively) and annually under CECONY's gas rate plan and O&R New York's electric and gas rate plans (January through December). Differences are accrued with interest each month for CECONY and O&R New York’s electric customers and after the annual deferral period ends for CECONY and O&R New York’s gas customers for refund to, or recovery from customers, as applicable. Generally, the refund to or recovery from customers begins August and February of each year over an ensuing six-month period for CECONY's electric customers and February of each year over an ensuing twelve-month period for CECONY's gas and O&R New York's electric and gas customers.
New Jersey State Regulation
In March 2020, New Jersey Governor Murphy declared a Public Health Emergency and State of Emergency for the State of New Jersey. Since that declaration, the NJBPU and RECO have mitigated the potential impact of the COVID-19 pandemic on RECO, its customers and other stakeholders. New Jersey designated utilities, including RECO, as essential businesses that were able to continue a portion of their work. RECO modified or suspended certain work in the state. In March 2020, RECO began suspending late payment charges, terminations for non-payment, and no access fees during the COVID-19 pandemic. The suspension of these fees is not expected to be material.
In July 2020, the NJBPU authorized RECO and other New Jersey utilities to create a COVID-19-related regulatory asset by deferring prudently incurred incremental costs related to COVID-19 beginning on March 9, 2020, and through the later of September 30, 2021, or 60 days after the emergency declaration is no longer in effect. As of June 30, 2020, RECO had not yet deferred any incremental costs related to COVID-19 and such costs are not expected to be material.
Federal Regulation
In March 2020, the North American Electric Reliability Corporation (NERC) issued guidance that the effects of the COVID-19 pandemic will be considered an acceptable basis for non-compliance with certain NERC Reliability Standards requirements that would have required action between March 1, 2020 and July 31, 2020. In addition, it suspended on-site NERC compliance audits until at least July 31, 2020.
Also in March 2020, FERC announced several actions to ease regulatory obligations in response to the COVID-19 pandemic. These include postponement of certain filing deadlines and the suspension of all audit site visits and investigative testimony.
In April 2020, FERC announced it would expeditiously review and act on requests for relief in response to the COVID-19 pandemic, give priority to processing filings that contribute to the business continuity of regulated entities’ energy infrastructure and exercise prosecutorial discretion when addressing events arising during the COVID-19 pandemic. FERC also approved a blanket waiver of requirements in Open Access Transmission Tariffs that require entities to hold meetings in-person and to provide or obtain notarized documents.
Gas Safety
In March 2020, the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) issued a notice staying enforcement of certain federal operator qualification, control room management and drug testing requirements during the COVID-19 pandemic. The notice also announced that PHMSA would exercise discretion in its overall enforcement of other parts of the pipeline safety regulations. The NYSPSC also provided guidance that it was staying enforcement of many of the same pipeline safety requirements identified in the March 2020 PHMSA notice.
In April 2020, the NYSPSC issued an order that extended the deadlines to complete certain gas inspections by all New York gas utilities, including CECONY and O&R, from April 1, 2020 to August 1, 2020.
Other Regulatory Matters
In August 2018, the NYSPSC ordered CECONY to begin on January 1, 2019 to credit the company's electric and gas customers, and to begin on October 1, 2018 to credit its steam customers, with the net benefits of the federal
24

Tax Cuts and Jobs Act of 2017 (TCJA) as measured based on amounts reflected in its rate plans prior to the enactment of the TCJA in December 2017. The net benefits include the revenue requirement impact of the reduction in the corporate federal income tax rate to 21 percent, the elimination for utilities of bonus depreciation and the amortization of excess deferred federal income taxes.
CECONY, under its electric rate plan that was approved in January 2020, is amortizing its TCJA net benefits prior to January 1, 2019 allocable to its electric customers ($377 million) over a three-year period, the “protected” portion of its net regulatory liability for future income taxes related to certain accelerated tax depreciation benefits allocable to its electric customers ($1,663 million) over the remaining lives of the related assets and the remainder, or “unprotected” portion of the net regulatory liability allocable to its electric customers ($784 million) over a five-year period. CECONY, under its gas rate plan that was approved in January 2020, is amortizing its remaining TCJA net benefits prior to January 1, 2019 allocable to its gas customers ($63 million) over a two-year period, the protected portion of its net regulatory liability for future income taxes allocable to its gas customers ($725 million) over the remaining lives of the related assets and the unprotected portion of the net regulatory liability allocable to its gas customers ($107 million) over a five-year period.
CECONY's net benefits prior to October 1, 2018 allocable to the company’s steam customers ($15 million) are being amortized over a three-year period. CECONY’s net regulatory liability for future income taxes, including both the protected and unprotected portions, allocable to the company’s steam customers ($185 million) is being amortized over the remaining lives of the related assets (with the amortization period for the unprotected portion subject to review in its next steam rate proceeding).
O&R, under its current electric and gas rate plans, has reflected its TCJA net benefits in its electric and gas rates beginning as of January 1, 2019. Under the rate plans, O&R is amortizing its net benefits prior to January 1, 2019 ($22 million) over a three-year period, the protected portion of its net regulatory liability for future income taxes ($123 million) over the remaining lives of the related assets and the unprotected portion ($30 million) over a fifteen-year period.
In January 2018, the NYSPSC issued an order initiating a focused operations audit of the income tax accounting of certain utilities, including CECONY and O&R. The Utilities are unable to estimate the amount or range of their possible loss related to this matter. At June 30, 2020, the Utilities had not accrued a liability related to this matter.
In March 2018, Winter Storms Riley and Quinn caused damage to the Utilities’ electric distribution systems and interrupted service to approximately 209,000 CECONY customers, 93,000 O&R customers and 44,000 RECO customers. At June 30, 2020, CECONY's costs related to March 2018 storms, including Riley and Quinn, amounted to $134 million, including operation and maintenance expenses reflected in its electric rate plan ($15 million), operation and maintenance expenses charged against a storm reserve pursuant to its electric rate plan ($84 million), capital expenditures ($29 million) and removal costs ($6 million). At June 30, 2020, O&R and RECO costs related to 2018 storms amounted to $43 million and $17 million, respectively, most of which were deferred as regulatory assets pursuant to their electric rate plans. In January 2019, O&R began recovering its deferred storm costs over a six-year period in accordance with its New York electric rate plan. In February 2020, RECO began recovering its deferred storm costs over a four-year period in accordance with its New Jersey electric rate plan. The NYSPSC investigated the preparation and response to the storms by CECONY, O&R, and other New York electric utilities, including all aspects of their emergency response plans. In April 2019, following the issuance of a NYSPSC staff report on the investigation, the NYSPSC ordered the utilities to show cause why the NYSPSC should not commence a penalty action against them for violating their emergency response plans. In July 2020, CECONY, O&R and NYSPSC Staff executed a settlement agreement, subject to NYSPSC approval, that resolves this matter. At June 30, 2020, CECONY and O&R accrued $5.6 million and $0.85 million, respectively, for the benefit of electric customers related to this matter.
In July 2018, the NYSPSC commenced an investigation into the rupture of a CECONY steam main located on Fifth Avenue and 21st Street in Manhattan. Debris from the incident included dirt and mud containing asbestos. The response to the incident required the closing of buildings and streets for various periods. The NYSPSC has commenced an investigation. As of June 30, 2020, with respect to the incident, the company incurred operating costs of $17 million for property damage, clean-up and other response costs and invested $9 million in capital and retirement costs. At June 30, 2020, the company accrued $3 million to an Other current liabilities account related to this matter.
25

In March 2019, the NYSPSC ordered CECONY to show cause why the NYSPSC should not commence a penalty action and prudence proceeding against CECONY for alleged violations of gas operator qualification, performance, and inspection requirements. At December 31, 2019, the company had an accrued regulatory liability related to this matter of $10 million, and at March 31, 2020, the company accrued an additional regulatory liability of $5 million. In April 2020, the NYSPSC approved a $15 million settlement agreement for the benefit of CECONY’s gas customers between CECONY and NYSPSC staff related to this matter.
On July 13, 2019, electric service was interrupted to approximately 72,000 CECONY customers on the west side of Manhattan. The NYSPSC and the Northeast Power Coordinating Council, a regional reliability entity, are investigating the July 13, 2019 power outage. Pursuant to the major outage reliability performance provisions of its electric rate plan, as a result of the July 13, 2019 power outage, CECONY recorded a $5 million negative revenue adjustment. The NYSPSC is also investigating other CECONY power outages that occurred in July 2019, primarily in the Flatbush area of Brooklyn. Primarily due to these outages, pursuant to the rate plan’s annual non-network outage frequency and non-network outage duration reliability performance provisions, the company recorded a $10 million negative revenue adjustment at December 31, 2019. The company is unable to estimate the amount or range of its possible additional loss related to these power outages.
In May 2020, an executive order was issued prohibiting the acquisition, importation, transfer or installation of certain bulk-power system electric equipment that is sourced from foreign adversaries. The scope and effect will be determined by regulations to be issued pursuant to the order. The Companies are unable to predict the impact on them of such regulations.
In August 2020, Tropical Storm Isaias caused significant damage to the Utilities’ electric distribution system and interrupted service to approximately 300,000 CECONY electric customers and approximately 225,000 O&R electric customers. To restore service to their customers and repair their energy systems, the Utilities are incurring operating costs and making capital expenditures, the amount of which the Utilities are unable to estimate at this time. The Utilities’ rate plans provide for operating costs and capital expenditures under different provisions. The Utilities expect that most of their operating expenses attributable to Tropical Storm Isaias will be deferred for recovery as a regulatory asset under their electric rate plans. The Utilities’ capital expenditures, up to specified levels, are reflected in rates under their rate plans. The Utilities’ New York electric rate plans include provisions for revenue decoupling, as a result of which delivery revenues generally are not affected by changes in delivery volumes from levels assumed when rates were approved. The provisions of the Utilities’ New York electric rate plans that impose penalties for operating performance provide for exceptions for major storms and catastrophic events beyond the control of the companies, including natural disasters such as hurricanes and floods. In August 2020, New York State Governor Cuomo directed the New York State Department of Public Service to investigate the preparation and performance of New York utilities in connection with Tropical Storm Isaias. The Companies are unable to estimate the amount or range of their possible loss in connection with the storm.

In January 2020, Con Edison issued 1,050,000 shares of its common stock for $88 million upon physical settlement of the remaining shares subject to its May 2019 forward sale agreement.
In March 2020, CECONY issued $600 million aggregate principal amount of 3.35 percent debentures, due 2030 and $1,000 million aggregate principal amount of 3.95 percent debentures, due 2050.

The carrying amounts and fair values of long-term debt at June 30, 2020 and December 31, 2019 were:

(Millions of Dollars) | 2020 | 2019
Long-Term Debt (including current portion) (a) | Carrying Amount | Fair Value | Carrying Amount | Fair Value
Con Edison | $21,114 | $25,183 | $19,973 | $22,738
CECONY | $16,194 | $20,001 | $14,964 | $17,505

(a) | Amounts shown are net of unamortized debt expense and unamortized debt discount of $196 million and $170 million for Con Edison and CECONY, respectively, as of June 30, 2020 and $178 million and $151 million for Con Edison and CECONY, respectively, as of December 31, 2019.

The fair values of the Companies' long-term debt have been estimated primarily using available market information and at June 30, 2020 are classified as Level 2 (see Note N).
As a result of the January 2019 PG&E bankruptcy (see "Long-Lived and Intangible Assets" in Note A), during the first quarter of 2019, Con Edison reclassified on its consolidated balance sheet the PG&E-related non-recourse project debt that was included in long-term debt to long-term debt due within one year. At December 31, 2019, long-term debt due within one year included $1,001 million of PG&E-related project debt. At June 30, 2020, due to the likelihood of PG&E’s plan of reorganization becoming effective, the company’s PG&E-related non-recourse project debt with a maturity longer than one year ($898 million) was reclassified from long-term debt due within one year to long-term debt. In July 2020, PG&E’s plan of reorganization became effective, and PG&E assumed all of the PG&E PPAs.
Note D – Short-Term Borrowing
At June 30, 2020, Con Edison had $1,813 million of commercial paper outstanding of which $1,115 million was outstanding under CECONY’s program. The weighted average interest rate at June 30, 2020 was 0.2 percent for both Con Edison and CECONY. At December 31, 2019, Con Edison had $1,692 million of commercial paper outstanding of which $1,137 million was outstanding under CECONY’s program. The weighted average interest rate at December 31, 2019 was 2.0 percent for both Con Edison and CECONY.
At June 30, 2020 and December 31, 2019, no loans were outstanding under the Companies' December 2016 credit agreement (Credit Agreement). An immaterial amount of letters of credit were outstanding under the Credit Agreement as of June 30, 2020 and December 31, 2019.
In July 2020, Con Edison borrowed $820 million pursuant to an April 2020 credit agreement that was amended in June 2020 (as amended, the Supplemental Credit Agreement). Con Edison used the proceeds from the borrowing for general corporate purposes, including repayment of short-term debt bearing interest at variable rates. Pursuant to the Supplemental Credit Agreement, the borrowing bears interest at a variable rate and was converted to a term loan that matures on March 29, 2021 (the “Term Loan”). Con Edison has the option to prepay the Term Loan. Subject to certain exceptions, the Term Loan under the Supplemental Credit Agreement is subject to mandatory prepayment with the net cash proceeds of debt or equity issuances by Con Edison or its non-regulated subsidiaries.
Pursuant to the Supplemental Credit Agreement, upon a change of control of, or upon an event of default by Con Edison, the lenders may declare the Term Loan immediately due and payable. Events of Default include Con Edison exceeding at any time a ratio of consolidated debt to consolidated total capital of 0.65 to 1; having liens on its assets in an aggregate amount exceeding five percent of its consolidated total capital, subject to certain exceptions; Con Edison or any of its subsidiaries failing to make one or more payments in respect of other material financial obligations (in excess of an aggregate $150 million of debt or derivative obligations other than non-recourse debt) when due or within any applicable grace period; the occurrence of an event or condition which results in the acceleration of the maturity of any material debt (in excess of an aggregate $150 million of debt other than non-recourse debt) or enables the holders of such debt to accelerate the maturity thereof; and other customary events of default.

Components of net periodic benefit cost other than service cost are presented outside of operating income on the Companies' consolidated income statements, and only the service cost component is eligible for capitalization. Accordingly, the service cost component is included in the line "Other operations and maintenance" and the non-service cost components are included in the line "Other deductions" in the Companies' consolidated income statements.
Expected Contributions
Based on estimates as of June 30, 2020, Con Edison and CECONY expect to make contributions to the pension plans during 2020 of $474 million (of which $434 million is to be made by CECONY). The Companies’ policy is to fund the total periodic benefit cost of the qualified plan to the extent tax deductible and to also contribute to the non-qualified supplemental plans. During the first six months of 2020, the Companies contributed $79 million to the pension plans, of which $78 million was made by CECONY. CECONY also contributed $18 million to the external trust for its non-qualified supplemental plan.

Expected Contributions
Based on estimates as of June 30, 2020, Con Edison and CECONY expect to make a contribution of $3 million (all of which is to be made by CECONY) to the other postretirement benefit plans in 2020. The Companies' policy is to fund the total periodic benefit cost of the plans to the extent tax deductible.
Note G – Environmental Matters
Superfund Sites
Hazardous substances, such as asbestos, polychlorinated biphenyls (PCBs) and coal tar, have been used or generated in the course of operations of the Utilities and their predecessors and are present at sites and in facilities and equipment they currently or previously owned, including sites at which gas was manufactured or stored.
The Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 and similar state statutes (Superfund) impose joint and several liability, regardless of fault, upon generators of hazardous substances for investigation and remediation costs (which include costs of demolition, removal, disposal, storage, replacement, containment and monitoring) and natural resource damages. Liability under these laws can be material and may be imposed for contamination from past acts, even though such past acts may have been lawful at the time they occurred. The sites at which the Utilities have been asserted to have liability under these laws, including their manufactured gas plant sites and any neighboring areas to which contamination may have migrated, are referred to herein as “Superfund Sites.”
For Superfund Sites where there are other potentially responsible parties and the Utilities are not managing the site investigation and remediation, the accrued liability represents an estimate of the amount the Utilities will need to
30

pay to investigate and, where determinable, discharge their related obligations. For Superfund Sites (including the manufactured gas plant sites) for which one of the Utilities is managing the investigation and remediation, the accrued liability represents an estimate of the company’s share of the undiscounted cost to investigate the sites and, for sites that have been investigated in whole or in part, the cost to remediate the sites, if remediation is necessary and if a reasonable estimate of such cost can be made. Remediation costs are estimated in light of the information available, applicable remediation standards and experience with similar sites.
The accrued liabilities and regulatory assets related to Superfund Sites at June 30, 2020 and December 31, 2019 were as follows:

| Con Edison | CECONY
(Millions of Dollars) | 2020 | 2019 | 2020 | 2019
Accrued Liabilities: |  |  |  |
Manufactured gas plant sites | $633 | $640 | $554 | $561
Other Superfund Sites | 101 | 94 | 100 | 93
Total | $734 | $734 | $654 | $654
Regulatory assets | $729 | $732 | $648 | $647

Most of the accrued Superfund Site liability relates to sites that have been investigated, in whole or in part. However, for some of the sites, the extent and associated cost of the required remediation has not yet been determined. As investigations progress and information pertaining to the required remediation becomes available, the Utilities expect that additional liability may be accrued, the amount of which is not presently determinable but may be material. The Utilities are permitted to recover or defer as regulatory assets (for subsequent recovery through rates) prudently incurred site investigation and remediation costs.
Environmental remediation costs incurred related to Superfund Sites for the three and six months ended June 30, 2020 and 2019 were as follows:

| For the Three Months Ended June 30,
| Con Edison | CECONY
(Millions of Dollars) | 2020 | 2019 | 2020 | 2019
Remediation costs incurred | $3 | $8 | $3 | $6

| For the Six Months Ended June 30,
| Con Edison | CECONY
(Millions of Dollars) | 2020 | 2019 | 2020 | 2019
Remediation costs incurred | $8 | $11 | $8 | $8

Insurance and other third-party recoveries received by Con Edison or CECONY were immaterial for the three and six months ended June 30, 2020 and 2019.
In 2019, Con Edison and CECONY estimated that for their manufactured gas plant sites (including CECONY’s Astoria site), the aggregate undiscounted potential liability for the investigation and remediation of coal tar and/or other environmental contaminants could range up to $2.8 billion and $2.6 billion, respectively. These estimates were based on the assumption that there is contamination at all sites, including those that have not yet been fully investigated and additional assumptions about the extent of the contamination and the type and extent of the remediation that may be required. Actual experience may be materially different.
31

Asbestos Proceedings
Suits have been brought in New York State and federal courts against the Utilities and many other defendants, wherein a large number of plaintiffs sought large amounts of compensatory and punitive damages for deaths and injuries allegedly caused by exposure to asbestos at various premises of the Utilities. The suits that have been resolved, which are many, have been resolved without any payment by the Utilities, or for amounts that were not, in the aggregate, material to them. The amounts specified in all the remaining thousands of suits total billions of dollars; however, the Utilities believe that these amounts are greatly exaggerated, based on the disposition of previous claims. At June 30, 2020, Con Edison and CECONY have accrued their estimated aggregate undiscounted potential liabilities for these suits and additional suits that may be brought over the next 15 years as shown in the following table. These estimates were based upon a combination of modeling, historical data analysis and risk factor assessment. Courts have begun, and unless otherwise determined on appeal may continue, to apply different standards for determining liability in asbestos suits than the standard that applied historically. As a result, the Companies currently believe that there is a reasonable possibility of an exposure to loss in excess of the liability accrued for the suits. The Companies are unable to estimate the amount or range of such loss. In addition, certain current and former employees have claimed or are claiming workers’ compensation benefits based on alleged disability from exposure to asbestos. CECONY is permitted to defer as regulatory assets (for subsequent recovery through rates) costs incurred for its asbestos lawsuits and workers’ compensation claims.
The accrued liability for asbestos suits and workers’ compensation proceedings (including those related to asbestos exposure) and the amounts deferred as regulatory assets for the Companies at June 30, 2020 and December 31, 2019 were as follows:

| Con Edison | CECONY
(Millions of Dollars) | 2020 |  | 2019 | 2020 |  | 2019
Accrued liability – asbestos suits | $8 | $8 | $7 | $7
Regulatory assets – asbestos suits | $8 | $8 | $7 | $7
Accrued liability – workers’ compensation | $75 | $78 | $70 | $73
Regulatory assets – workers’ compensation |  | $— |  | $3 |  | $— |  | $3

Note H – Other Material Contingencies
Manhattan Explosion and Fire
On March 12, 2014, two multi-use five-story tall buildings located on Park Avenue between 116 th and 117 th Streets in Manhattan were destroyed by an explosion and fire. CECONY had delivered gas to the buildings through service lines from a distribution main located below ground on Park Avenue. Eight people died and more than 50 people were injured. Additional buildings were also damaged. The National Transportation Safety Board (NTSB) investigated. The parties to the investigation included the company, the City of New York, the Pipeline and Hazardous Materials Safety Administration and the NYSPSC. In June 2015, the NTSB issued a final report concerning the incident, its probable cause and safety recommendations. The NTSB determined that the probable cause of the incident was (1) the failure of a defective fusion joint at a service tee (which joined a plastic service line to a plastic distribution main) installed by the company that allowed gas to leak from the distribution main and migrate into a building where it ignited and (2) a breach in a City sewer line that allowed groundwater and soil to flow into the sewer, resulting in a loss of support for the distribution main, which caused it to sag and overstressed the defective fusion joint. The NTSB also made safety recommendations, including recommendations to the company that addressed its procedures for the preparation and examination of plastic fusions, training of its staff on conditions for notifications to the City’s Fire Department and extension of its gas main isolation valve installation program. In February 2017, the NYSPSC approved a settlement agreement with the company related to the NYSPSC's investigations of the incident and the practices of qualifying persons to perform plastic fusions. Pursuant to the agreement, the company is providing $27 million of future benefits to customers (for which it has accrued a regulatory liability) and will not recover from customers $126 million of costs for gas emergency response activities that it had previously incurred and expensed. Approximately eighty suits are pending against the company seeking generally unspecified damages and, in some cases, punitive damages, for wrongful death, personal injury, property damage and business interruption. The company has notified its insurers of the incident and believes that the policies in force at the time of the incident will cover the company’s costs, in excess of a required retention (the amount of which is not material), to satisfy any liability it may have for damages in connection with the incident. The company is unable to estimate the amount or range of its possible loss for damages related to the incident. At June 30, 2020, the company had not accrued a liability for damages related to the incident.

Other Contingencies
For information about the PG&E bankruptcy, see "Long-Lived and Intangible Assets" in Note A and Note C. Also, for additional contingencies, see "Other Regulatory Matters" in Note B and “Uncertain Tax Positions” in Note J.
Guarantees
Con Edison and its subsidiaries have entered into various agreements providing financial or performance assurance primarily to third parties on behalf of their subsidiaries. Maximum amounts guaranteed by Con Edison under these agreements totaled $1,944 million and $1,831 million at June 30, 2020 and December 31, 2019, respectively.
A summary, by type and term, of Con Edison’s total guarantees under these agreements at June 30, 2020 is as follows:

Guarantee Type | 0 – 3 years | 4 – 10 years |  | > 10 years |  | Total
| (Millions of Dollars)
Con Edison Transmission | $362 | $186 |  | $— |  | $548
Energy transactions | 447 | 48 | 233 | 728

Other | 70 | — |  | — |  | 70
Total | $1,086 | $243 | $615 | $1,944

Con Edison Transmission — Con Edison has guaranteed payment by CET Electric of the contributions CET Electric agreed to make to New York Transco LLC (NY Transco). CET Electric owns a 45.7 percent interest in NY Transco. In April 2019, the New York Independent System Operator (NYISO) selected a transmission project that was jointly proposed by National Grid and NY Transco. The siting, construction and operation of the project will require approvals and permits from appropriate governmental agencies and authorities, including the NYSPSC. The NYISO indicated it will work with the developers to enter into agreements for the development and operation of the projects, including a schedule for entry into service by December 2023. Guarantee amounts shown includes the maximum possible required amount of CET Electric’s contributions for this project as calculated based on the assumptions that the project is completed at 175 percent of its estimated costs and NY Transco does not use any debt financing for the project.
Energy Transactions — Con Edison guarantees payments on behalf of the Clean Energy Businesses in order to facilitate physical and financial transactions in electricity, gas, pipeline capacity, transportation, oil, renewable energy credits and energy services. To the extent that liabilities exist under the contracts subject to these guarantees, such liabilities are included in Con Edison’s consolidated balance sheet.
Renewable Electric Production Projects — Con Edison and the Clean Energy Businesses guarantee payments on behalf of their wholly-owned subsidiaries associated with their investment in, or development for others of, solar and wind energy facilities.
Other — Other guarantees include $70 million in guarantees provided by Con Edison to Travelers Insurance Company for indemnity agreements for surety bonds in connection with operation of solar energy facilities and energy service projects of the Clean Energy Businesses.

34

The Companies are lessors under certain leases whereby the Companies own real estate and distribution poles and lease portions of them to others. Revenue under such leases was immaterial for Con Edison and CECONY for the three and six months ended June 30, 2020 and 2019.
Note J – Income Tax
In response to the economic impacts of the COVID-19 pandemic, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was signed into law on March 27, 2020. The CARES Act provides relief to corporate taxpayers by permitting a five-year carryback of net operating losses (NOLs) for tax years 2018, 2019 and 2020, removing the 80 percent limitation when applying the NOLs to carryback years, increasing the 30 percent limitation on interest deductibility to 50 percent of adjusted taxable income for tax years 2019 and 2020, and provides for certain employment tax credits and refunds for eligible employers.
Under the CARES Act, Con Edison will carryback its $29 million NOL from tax year 2018 to tax year 2013 generating a $2.5 million net tax refund for which a tax receivable was established in the first quarter of 2020. In addition, Con Edison recognized a discrete income tax benefit of $4 million in the first quarter of 2020, due to the higher federal statutory tax rate in 2013. The 2018 federal NOL was recorded at 21 percent and will be carried back to tax year 2013, which had a 35 percent federal statutory tax rate. This tax benefit was primarily recognized at the Clean Energy Businesses.
Con Edison’s income tax expense decreased to $9 million for the three months ended June 30, 2020 from $19 million for the three months ended June 30, 2019. The decrease in income tax expense is primarily due to an increase in the amortization of excess deferred federal income taxes due to CECONY’s new rate plan beginning in the first quarter of 2020, offset in part by higher income before income tax expense, the absence of the amortization of excess deferred state income taxes, higher state income taxes and higher allowance for uncollectible accounts.
CECONY’s income tax expense decreased to $7 million for the three months ended June 30, 2020 from $27 million for the three months ended June 30, 2019. The decrease in income tax expense is primarily due to lower income before income tax expense and an increase in the amortization of excess deferred federal income taxes due to CECONY’s new rate plan beginning in the first quarter of 2020, offset in part by the absence of the amortization of excess deferred state income taxes and higher allowance for uncollectible accounts.
Reconciliation of the difference between income tax expense and the amount computed by applying the prevailing statutory income tax rate to income before income taxes for the three months ended June 30, 2020 and 2019 is as follows:

| Con Edison | CECONY
(% of Pre-tax income) | 2020 |  | 2019 |  | 2020 |  | 2019 |
STATUTORY TAX RATE |  |  |  |
Federal | 21 | % | 21 | % | 21 | % | 21 | %
Changes in computed taxes resulting from: |  |  |  |
State income tax | 6 |  | 6 |  | 6 |  | 5 |
Amortization of excess deferred federal income taxes | (20 | ) | (9 | ) | (25 | ) | (9 | )
Taxes attributable to non-controlling interest | (2 | ) | (4 | ) | — |  | — |
Cost of removal | 4 |  | 2 |  | 5 |  | 2 |

Other | 1 |  | 1 |  | — |  | (1 | )
Effective tax rate | 4 | % | 10 | % | 4 | % | 15 | %

Con Edison’s income tax expense decreased to $64 million for the six months ended June 30, 2020 from $127 million for the six months ended June 30, 2019. The decrease in income tax expense is primarily due to lower income before income tax expense, an increase in the amortization of excess deferred federal income taxes due to CECONY’s new rate plan beginning in the first quarter of 2020, higher renewable energy credits and a $4 million income tax benefit due to the ability to carryback a net operating loss from the 2018 tax year to the 2013 tax year as

allowed under the CARES Act, offset in part by the absence of the amortization of excess deferred state income taxes and higher allowance for uncollectible accounts.
CECONY’s income tax expense decreased to $102 million for the six months ended June 30, 2020 from $151 million for the six months ended June 30, 2019. The decrease in income tax expense is primarily due to lower income before income tax expense, lower state income taxes and an increase in the amortization of excess deferred federal income taxes due to CECONY’s new rate plan beginning in the first quarter of 2020, offset in part by the absence of the amortization of excess deferred state income taxes and higher allowance for uncollectible accounts.
Reconciliation of the difference between income tax expense and the amount computed by applying the prevailing statutory income tax rate to income before income taxes for the six months ended June 30, 2020 and 2019 is as follows:

| Con Edison | CECONY
(% of Pre-tax income) | 2020 |  | 2019 |  | 2020 |  | 2019 |
STATUTORY TAX RATE |  |  |  |
Federal | 21 | % | 21 | % | 21 | % | 21 | %

CECONY deferred as regulatory liabilities its estimated net benefits for its electric service under the TCJA for the six months ended June 30, 2019. The net benefits include the revenue requirement impact of the reduction in the corporate federal income tax rate to 21 percent, the elimination for utilities of bonus depreciation and the amortization of excess deferred federal income taxes the utilities collected from customers that will not need to be paid to the Internal Revenue Service under the TCJA. See “Other Regulatory Matters” in Note B.
Under CECONY’s new electric rate plan that began in the first quarter of 2020, the deferral of its net benefits for its electric service ceased and is included in its new rates. Additionally, the amortization of the unprotected excess deferred federal income taxes for its electric and gas services is being amortized over a five-year period, which increased the tax benefit in the first six months of 2020.
Uncertain Tax Positions
At June 30, 2020, the estimated liability for uncertain tax positions for Con Edison was $13 million ($3 million for CECONY). Con Edison reasonably expects to resolve within the next twelve months approximately $1 million of various federal and state uncertainties due to the expected completion of ongoing tax examinations, of which the entire amount, if recognized, would reduce Con Edison's effective tax rate. The amount related to CECONY is immaterial. The total amount of unrecognized tax benefits, if recognized, that would reduce Con Edison’s effective tax rate is $13 million ($12 million, net of federal taxes) with $3 million attributable to CECONY.
The Companies recognize interest on liabilities for uncertain tax positions in interest expense and would recognize penalties, if any, in operating expenses in the Companies’ consolidated income statements. In the six months ended June 30, 2020, the Companies recognized an immaterial amount of interest expense and no penalties for uncertain tax positions in their consolidated income statements. At June 30, 2020 and December 31, 2019, the Companies recognized an immaterial amount of accrued interest on their consolidated balance sheets.

Ending balance as of June 30, | $22 | $47 |  | $35 | $18 |

(a) | Unbilled contract revenue represents accumulated incurred costs and earned profits on contracts (revenue arrangements), which have been recorded as revenue, but have not yet been billed to customers, and which represent contract assets as defined in Topic 606. Substantially all accrued unbilled contract revenue is expected to be collected within one year. Unbilled contract revenue arises from the cost-to-cost method of revenue recognition. Unbilled contract revenue from fixed-price type contracts is converted to billed receivables when amounts are invoiced to customers according to contractual billing terms, which generally occur when deliveries or other performance milestones are completed.

(b) | Unearned revenue represents a liability for billings to customers in excess of earned revenue, which are contract liabilities as defined in Topic 606.

(c) | Additions for unbilled contract revenue and subtractions for unearned revenue represent additional revenue earned. Additions for unearned revenue and subtractions for unbilled contract revenue represent billings. Activity also includes appropriate balance sheet classification for the period.

(d) | Of the subtractions from unearned revenue, $1 million and $2 million were included in the balances as of January 1, 2020 and 2019, respectively.

As of June 30, 2020, the aggregate amount of the remaining fixed performance obligations of the Clean Energy Businesses under contracts with customers for energy services is $70 million, of which $34 million will be recognized within the next two years, and the remaining $36 million will be recognized pursuant to long-term service and maintenance agreements.
In March 2020, the Utilities began suspending new late payment charges and certain other fees for all customers. The estimated amount of these foregone revenues for the three months ended June 30, 2020 was $21 million and $20 million for Con Edison and CECONY, respectively. The estimated amount of these foregone revenues for the six months ended June 30, 2020 was $24 million and $23 million for Con Edison and CECONY, respectively. The Utilities also began providing payment extensions for all customers that were scheduled to be disconnected prior to the start of the COVID-19 pandemic. See "COVID-19 Regulatory Matters" in Note B.
Note L – Financial Information by Business Segment
Con Edison’s principal business segments are CECONY’s regulated utility activities, O&R’s regulated utility activities, the Clean Energy Businesses and Con Edison Transmission. CECONY’s principal business segments are its regulated electric, gas and steam utility activities. The financial data for the business segments for the three and six months ended June 30, 2020 and 2019 were as follows:

Note M – Derivative Instruments and Hedging Activities
Con Edison’s subsidiaries hedge market price fluctuations associated with physical purchases and sales of electricity, natural gas, steam and, to a lesser extent, refined fuels by using derivative instruments including futures, forwards, basis swaps, options, transmission congestion contracts and financial transmission rights contracts. These are economic hedges, for which the Utilities and the Clean Energy Business do not elect hedge accounting. The Clean Energy Businesses use interest rate swaps to manage the risks associated with interest rates related to outstanding and expected future debt issuances and borrowings. Derivatives are recognized on the consolidated balance sheet at fair value (see Note N), unless an exception is available under the accounting rules for derivatives and hedging. Qualifying derivative contracts that have been designated as normal purchases or normal sales contracts are not reported at fair value under the accounting rules.
39

The fair values of the Companies’ derivatives including the offsetting of assets and liabilities on the consolidated balance sheet at June 30, 2020 and December 31, 2019 were:

(Millions of Dollars) | 2020 |  | 2019 |

Net fair value derivative assets/(liabilities) | $(177) | $3 | $(174) |  | $(124) | $17 | $(107) |

(a) | Derivative instruments and collateral were offset on the consolidated balance sheet as applicable under the accounting rules. The Companies enter into master agreements for their commodity derivatives. These agreements typically provide offset in the event of contract termination. In such case, generally the non-defaulting party’s payable will be offset by the defaulting party’s payable. The non-defaulting party will customarily notify the defaulting party within a specific time period and come to an agreement on the early termination amount.

(b) | At June 30, 2020 and December 31, 2019, margin deposits for Con Edison ($7 million and $9 million, respectively) and CECONY ($6 million and $8 million, respectively) were classified as derivative assets on the consolidated balance sheet, but not included in the table. Margin is collateral, typically cash, that the holder of a derivative instrument is required to deposit in order to transact on an exchange and to cover its potential losses with its broker or the exchange.

(c) | Includes amounts for interest rate swaps of $(21) million in current liabilities and $(108) million in noncurrent liabilities. At June 30, 2020, the Clean Energy Businesses had interest rate swaps with notional amounts of $892 million. The expiration dates of the swaps range from 2024-2041.

(d) | Includes amounts for interest rate swaps of $1 million in noncurrent assets, $(7) million in current liabilities and $(34) million in noncurrent liabilities. At December 31, 2019, the Clean Energy Businesses had interest rate swaps with notional amounts of $919 million. The expiration dates of the swaps range from 2024-2041.

The Utilities generally recover their prudently incurred fuel, purchased power and gas costs, including hedging gains and losses, in accordance with rate provisions approved by the applicable state utility regulators. In accordance with the accounting rules for regulated operations, the Utilities record a regulatory asset or liability to defer recognition of unrealized gains and losses on their electric and gas derivatives. As gains and losses are realized in future periods, they will be recognized as purchased power, gas and fuel costs in the Companies’ consolidated income statements.
The Clean Energy Businesses record realized and unrealized gains and losses on their derivative contracts in gas purchased for resale and non-utility revenue in the reporting period in which they occur. The Clean Energy Businesses record changes in the fair value of their interest rate swaps in other interest expense at the end of each reporting period. Management believes that these derivative instruments represent economic hedges that mitigate exposure to fluctuations in commodity prices and interest rates.

The Companies are exposed to credit risk related to transactions entered into primarily for the various energy supply and hedging activities by the Utilities and the Clean Energy Businesses. Credit risk relates to the loss that may result from a counterparty’s nonperformance. The Companies use credit policies to manage this risk, including an established credit approval process, monitoring of counterparty limits, netting provisions within agreements, collateral or prepayment arrangements, credit insurance and credit default swaps. The Companies measure credit risk exposure as the replacement cost for open energy commodity and derivative positions plus amounts owed from counterparties for settled transactions. The replacement cost of open positions represents unrealized gains, net of any unrealized losses where the Companies have a legally enforceable right to offset.
At June 30, 2020, Con Edison and CECONY had $222 million and $19 million of credit exposure in connection with open energy supply net receivables and hedging activities, net of collateral, respectively. Con Edison’s net credit exposure consisted of $94 million with independent system operators, $57 million with non-investment grade/non-rated counterparties, $57 million with investment-grade counterparties and $14 million with commodity exchange brokers. CECONY’s net credit exposure consisted of $10 million with commodity exchange brokers, $9 million with investment-grade counterparties and an immaterial amount with non-investment-grade counterparties.
The collateral requirements associated with, and settlement of, derivative transactions are included in net cash flows from operating activities in the Companies’ consolidated statement of cash flows. Most derivative instrument contracts contain provisions that may require a party to provide collateral on its derivative instruments that are in a net liability position. The amount of collateral to be provided will depend on the fair value of the derivative instruments and the party’s credit ratings.
The following table presents the aggregate fair value of the Companies’ derivative instruments with credit-risk-related contingent features that are in a net liability position, the collateral posted for such positions and the additional collateral that would have been required to be posted had the lowest applicable credit rating been reduced one level and to below investment grade at June 30, 2020:

(Millions of Dollars) | Con Edison (a) |  | CECONY (a) |

Additional collateral (b) (downgrade to below investment grade from current ratings) | 84 | (c) | 67 | (c)

(a) | Non-derivative transactions for the purchase and sale of electricity and gas and qualifying derivative instruments, which have been designated as normal purchases or normal sales, are excluded from the table. These transactions primarily include purchases of electricity from independent system operators. In the event the Utilities and the Clean Energy Businesses were no longer extended unsecured credit for such purchases, the Companies would be required to post $20 million of additional collateral at June 30, 2020. For certain other such non-derivative transactions, the Companies could be required to post collateral under certain circumstances, including in the event counterparties had reasonable grounds for insecurity.

(b) | The Companies measure the collateral requirements by taking into consideration the fair value amounts of derivative instruments that contain credit-risk-related contingent features that are in a net liability position plus amounts owed to counterparties for settled transactions and amounts required by counterparties for minimum financial security. The fair value amounts represent unrealized losses, net of any unrealized gains where the Companies have a legally enforceable right to offset.

(c) | Derivative instruments that are net assets have been excluded from the table. At June 30, 2020, if Con Edison had been downgraded to below investment grade, it would have been required to post additional collateral for such derivative instruments of $37 million.

Note N – Fair Value Measurements
The accounting rules for fair value measurements and disclosures define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, which refer broadly to assumptions that market participants use in pricing assets or liabilities. These inputs can be readily observable, market corroborated, or generally unobservable firm inputs. The Companies often make certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk, and the risks inherent in the inputs to valuation techniques. The Companies use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.
The accounting rules for fair value measurements and disclosures established a fair value hierarchy, which prioritizes the inputs to valuation techniques used to measure fair value in three broad levels. The rules require that assets and liabilities be classified in their entirety based on the level of input that is significant to the fair value measurement. Assessing the significance of a particular input may require judgment considering factors specific to the asset or liability and may affect the valuation of the asset or liability and their placement within the fair value hierarchy. The
42

Companies classify fair value balances based on the fair value hierarchy defined by the accounting rules for fair value measurements and disclosures as follows:

• | Level 1 – Consists of assets or liabilities whose value is based on unadjusted quoted prices in active markets at the measurement date. An active market is one in which transactions for assets or liabilities occur with sufficient frequency and volume to provide pricing information on an ongoing basis. This category includes contracts traded on active exchange markets valued using unadjusted prices quoted directly from the exchange.

• | Level 2 – Consists of assets or liabilities valued using industry standard models and based on prices, other than quoted prices within Level 1, that are either directly or indirectly observable as of the measurement date. The industry standard models consider observable assumptions including time value, volatility factors and current market and contractual prices for the underlying commodities, in addition to other economic measures. This category includes contracts traded on active exchanges or in over-the-counter markets priced with industry standard models.

• | Level 3 – Consists of assets or liabilities whose fair value is estimated based on internally developed models or methodologies using inputs that are generally less readily observable and supported by little, if any, market activity at the measurement date. Unobservable inputs are developed based on the best available information and subject to cost benefit constraints. This category includes contracts priced using models that are internally developed and contracts placed in illiquid markets. It also includes contracts that expire after the period of time for which quoted prices are available and internal models are used to determine a significant portion of the value.

Assets and liabilities measured at fair value on a recurring basis as of June 30, 2020 and December 31, 2019 are summarized below.

(a) | The Companies’ policy is to review the fair value hierarchy and recognize transfers into and transfers out of the levels at the end of each reporting period. Con Edison and CECONY had no transfers between levels 1, 2, and 3 during the six months ended June 30, 2020. Con Edison and CECONY had $24 million and $22 million, respectively, of commodity derivative liabilities transferred from level 3 to level 2 during the year ended December 31, 2019 because of availability of observable market data due to the decrease in the terms of certain contracts from beyond three years as of September 30, 2019 to less than three years as of December 31, 2019.

(b) | Level 2 assets and liabilities include investments held in the deferred compensation plan and/or non-qualified retirement plans, exchange-traded contracts where there is insufficient market liquidity to warrant inclusion in Level 1, certain over-the-counter derivative instruments for electricity, refined products and natural gas. Derivative instruments classified as Level 2 are valued using industry standard models that incorporate corroborated observable inputs; such as pricing services or prices from similar instruments that trade in liquid markets, time value and volatility factors.

(c) | The accounting rules for fair value measurements and disclosures require consideration of the impact of nonperformance risk (including credit risk) from a market participant perspective in the measurement of the fair value of assets and liabilities. At June 30, 2020 and December 31, 2019, the Companies determined that nonperformance risk would have no material impact on their financial position or results of operations.

43

(d) | Other assets are comprised of assets such as life insurance contracts within the deferred compensation plan and non-qualified retirement plans.

(e) | Amounts represent the impact of legally-enforceable master netting agreements that allow the Companies to net gain and loss positions and cash collateral held or placed with the same counterparties.

The employees in the Companies’ risk management group develop and maintain the Companies’ valuation policies and procedures for, and verify pricing and fair value valuation of, commodity derivatives and interest rate swaps. Under the Companies’ policies and procedures, multiple independent sources of information are obtained for forward price curves used to value commodity derivatives and interest rate swaps. Fair value and changes in fair value of commodity derivatives and interest rate swaps are reported on a monthly basis to the Companies’ risk committees, comprised of officers and employees of the Companies that oversee energy hedging at the Utilities and the Clean Energy Businesses. The risk management group reports to the Companies’ Vice President and Treasurer.

For the Utilities, realized gains and losses on Level 3 commodity derivative assets and liabilities are reported as part of purchased power, gas and fuel costs. The Utilities generally recover these costs in accordance with rate provisions approved by the applicable state public utilities regulators. Unrealized gains and losses for commodity derivatives are generally deferred on the consolidated balance sheet in accordance with the accounting rules for regulated operations.
44

For the Clean Energy Businesses, realized and unrealized gains and losses on Level 3 commodity derivative assets and liabilities are reported in non-utility revenues (immaterial for both periods) on the consolidated income statement for the three months ended June 30, 2020 and 2019. Realized and unrealized gains and losses on Level 3 commodity derivative assets and liabilities are reported in non-utility revenues ($1 million gain and $1 million loss) on the consolidated income statement for the six months ended June 30, 2020 and 2019. The change in fair value relating to Level 3 commodity derivative assets and liabilities held at June 30, 2020 and 2019 is included in non-utility revenues (immaterial for both periods) on the consolidated income statement for the three months ended June 30, 2020 and 2019. For the six months ended June 30, 2020 and 2019, the change in fair value relating to Level 3 commodity derivatives assets and liabilities is included in non-utility revenues ($1 million gain and $1 million loss) on the consolidated income statement.
Note O – Variable Interest Entities
The accounting rules for consolidation address the consolidation of a variable interest entity (VIE) by a business enterprise that is the primary beneficiary. A VIE is an entity that does not have a sufficient equity investment at risk to permit it to finance its activities without additional subordinated financial support, or whose equity investors lack the characteristics of a controlling financial interest. The primary beneficiary is the business enterprise that has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and either absorbs a significant amount of the VIE’s losses or has the right to receive benefits that could be significant to the VIE.
The Companies enter into arrangements including leases, partnerships and electricity purchase agreements, with various entities. As a result of these arrangements, the Companies retain or may retain a variable interest in these entities.
CECONY
CECONY has an ongoing long-term electricity purchase agreement with Brooklyn Navy Yard Cogeneration Partners, LP, a potential VIE. In 2019, a request was made of this counterparty for information necessary to determine whether the entity was a VIE and whether CECONY is the primary beneficiary; however, the information was not made available. The payments for this contract constitute CECONY’s maximum exposure to loss with respect to the potential VIE.
Clean Energy Businesses
In September 2019, the Clean Energy Businesses, which previously owned an 80 percent membership interest in OCI Solar San Antonio 4 LLC (Texas Solar 4), acquired the remaining 20 percent interest. As a result of the acquisition, Texas Solar 4 is a consolidated entity. Prior to the acquisition, Con Edison had a variable interest in Texas Solar 4, as to which Con Edison was the primary beneficiary since the power to direct the activities that most significantly impact the economics of Texas Solar 4 was held by the Clean Energy Businesses. Texas Solar 4 owns a project company that developed a 40 MW (AC) solar electric production project. Electricity generated by the project is sold pursuant to a long-term power purchase agreement. Con Edison's earnings from Texas Solar 4 for the three and six months ended June 30, 2019 were immaterial.
In December 2018, the Clean Energy Businesses completed its acquisition of Sempra Solar Holdings, LLC. Included in the acquisition were certain operating projects (Tax Equity Projects) with a noncontrolling tax equity investor to which a percentage of earnings, tax attributes and cash flows are allocated. The Tax Equity Projects are consolidated entities in which Con Edison has less than a 100 percent membership interest. Con Edison is the primary beneficiary since the power to direct the activities that most significantly impact the economics of the Tax Equity Projects is held by the Clean Energy Businesses. Electricity generated by the Tax Equity Projects is sold to utilities and municipalities pursuant to long-term power purchase agreements. For the three months ended June 30, 2020, the hypothetical liquidation at book value (HLBV) method of accounting for the Tax Equity Projects resulted in $12 million of income ($9 million, after tax) for the tax equity investor and $4 million of income ($3 million, after tax) for Con Edison. For the three months ended June 30, 2019, the HLBV method of accounting for the Tax Equity Projects resulted in $28 million of income ($21 million, after tax) for the tax equity investor and $15 million loss ($12 million, after tax) for Con Edison. For the six months ended June 30, 2020, the HLBV method of accounting for the Tax Equity Projects resulted in $29 million of income ($22 million, after tax) for the tax equity investor and a $10 million loss ($8 million, after tax) for Con Edison. For the six months ended June 30, 2019, the HLBV method of accounting for the Tax Equity Projects resulted in $49 million of income ($37 million, after tax) for the tax equity investor and a $34 million loss ($26 million, after tax) for Con Edison.
45

Con Edison has determined that the use of HLBV accounting is reasonable and appropriate to attribute income and loss to the tax equity investors. Using the HLBV method, the company's earnings from the projects are adjusted to reflect the income or loss allocable to the tax equity investors calculated based on how the project would allocate and distribute its cash if it were to sell all of its assets for their carrying amounts and liquidate at a particular point in time. Under the HLBV method, the company calculates the liquidation value allocable to the tax equity investors at the beginning and end of each period based on the contractual liquidation waterfall and adjusts its income for the period to reflect the change in the liquidation value allocable to the tax equity investors.
At June 30, 2020 and December 31, 2019, Con Edison’s consolidated balance sheet included the following amounts associated with its VIEs:

| Tax Equity Projects
| Great Valley Solar (c)(d) | Copper Mountain - Mesquite Solar (c)(e)
(Millions of Dollars) | 2020 | 2019 | 2020 | 2019
Non-utility property, less accumulated depreciation (f)(g) | $288 | $293 | $453 | $461
Other assets | 45 | 40 | 189 | 128
Total assets (a) | $333 | $333 | $642 | $589
Other liabilities | 15 | 17 | 69 | 18
Total liabilities (b) | $15 | $17 | $69 | $18

(a) | The assets of the Tax Equity Projects represent assets of a consolidated VIE that can be used only to settle obligations of the consolidated VIE.

(b) | The liabilities of the Tax Equity Projects represent liabilities of a consolidated VIE for which creditors do not have recourse to the general credit of the primary beneficiary.

(c) | Con Edison did not provide any financial or other support during the year that was not previously contractually required.

(d) | Great Valley Solar consists of the Great Valley Solar 1, Great Valley Solar 2, Great Valley Solar 3 and Great Valley Solar 4 projects, for which the noncontrolling interest of the tax equity investor was $73 million and $62 million at June 30, 2020 and December 31, 2019, respectively.

(e) | Copper Mountain - Mesquite Solar consists of the Copper Mountain Solar 4, Mesquite Solar 2 and Mesquite Solar 3 projects for which the noncontrolling interest of the tax equity investor was $140 million and $126 million at June 30, 2020 and December 31, 2019, respectively.

(f) | Non-utility property is reduced by accumulated depreciation of $13 million for Great Valley Solar and $23 million for Copper Mountain - Mesquite Solar at June 30, 2020.

(g) | Non-utility property is reduced by accumulated depreciation of $9 million for Great Valley Solar and $15 million for Copper Mountain - Mesquite Solar at December 31, 2019.

Note P – New Financial Accounting Standards
In December 2019, the FASB issued amendments to the guidance for income taxes through ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” The amendments in this update simplify the accounting for income taxes by removing certain exceptions such as: 1) the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items, 2) the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment, 3) the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary, and 4) the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. For public entities, the amendments are effective for reporting periods beginning after December 15, 2020. Early adoption is permitted. The Companies are in the process of evaluating the potential impact of the new guidance on the Companies’ financial position, results of operations and liquidity.
In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). The United Kingdom’s Financial Conduct Authority has announced that it intends to stop persuading or compelling banks to submit the London Interbank Offered Rate (“LIBOR”), a benchmark interest rate referenced in a variety of agreements, after 2021. ASU 2020-04 provides entities with optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The guidance is applied prospectively from any date beginning March 12, 2020. The optional relief is temporary and generally cannot be applied to contract modifications and hedging relationships entered into or evaluated after, December 31, 2022. The Companies do not expect the new guidance to have a material impact on their financial position, results of operations or liquidity.

Item 2: Management’s Discussion and Analysis of Financial Condition and Results of Operations
This combined management’s discussion and analysis of financial condition and results of operations (MD&A) relates to the consolidated financial statements (the Second Quarter Financial Statements) included in this report of two separate registrants: Consolidated Edison, Inc. (Con Edison) and Consolidated Edison Company of New York, Inc. (CECONY). As used in this report, the term the “Companies” refers to Con Edison and CECONY. CECONY is a subsidiary of Con Edison and, as such, information in this management’s discussion and analysis about CECONY applies to Con Edison.
This MD&A should be read in conjunction with the Second Quarter Financial Statements and the notes thereto, the MD&A in Item 7 of the Companies’ combined Annual Report on Form 10-K for the year ended December 31, 2019 (File Nos. 1-14514 and 1-1217, the Form 10-K) and the MD&A in Part 1, Item 2 of the Companies' combined Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2020 (File Nos. 1-14514 and 1-1217).
Information in any item of this report referred to in this discussion and analysis is incorporated by reference herein. The use of terms such as “see” or “refer to” shall be deemed to incorporate by reference into this discussion and analysis the information to which reference is made.
Con Edison, incorporated in New York State in 1997, is a holding company that owns all of the outstanding common stock of CECONY, Orange and Rockland Utilities, Inc. (O&R), Con Edison Clean Energy Businesses, Inc. and Con Edison Transmission, Inc. As used in this report, the term the “Utilities” refers to CECONY and O&R.

|  |  |  | Con Edison |  |  |  |
CECONY |  | O&R |  | Clean Energy Businesses |  | Con Edison Transmission
|  | • RECO |  |  |  | • CET Electric
|  |  |  |  |  | • CET Gas

Con Edison’s principal business operations are those of CECONY, O&R, the Clean Energy Businesses and Con Edison Transmission. CECONY’s principal business operations are its regulated electric, gas and steam delivery businesses. O&R’s principal business operations are its regulated electric and gas delivery businesses. The Clean Energy Businesses develop, own and operate renewable and energy infrastructure projects and provide energy-related products and services to wholesale and retail customers. Con Edison Transmission invests in electric transmission facilities and gas pipeline and storage facilities.
Con Edison seeks to provide shareholder value through continued dividend growth, supported by earnings growth in regulated utilities and contracted electric and gas assets. The company invests to provide reliable, resilient, safe and clean energy critical for New York City’s growing economy. The company is an industry leading owner and operator of contracted, large-scale solar generation in the United States. Con Edison is a responsible neighbor, helping the communities it serves become more sustainable.
CECONY
Electric
CECONY provides electric service to approximately 3.5 million customers in all of New York City (except a part of Queens) and most of Westchester County, an approximately 660 square mile service area with a population of more than nine million.
Gas
47

CECONY delivers gas to approximately 1.1 million customers in Manhattan, the Bronx, parts of Queens and most of Westchester County.
In January 2019, due to gas supply constraints, CECONY filed notice with the NYSPSC to establish a temporary moratorium beginning in March 2019 on new applications for firm gas service in most of Westchester County. In July 2020, the company filed a gas planning analysis with the NYSPSC that stated the moratorium is expected to be lifted when increased pipeline capacity is achieved upon completion of the Tennessee pipeline’s 300L East project or peak demand is reduced through efficiency and other demand side reductions to a level that would enable the company to lift the moratorium. Assuming timely regulatory approvals, the Tennessee pipeline project is expected to be completed by November 2023.
In June 2020, CECONY decreased its five-year forecast of average annual growth of the peak gas demand in its service area at design conditions from approximately 1.5 percent (for 2020 to 2024) to approximately 1.4 percent (for 2021 to 2025). The decrease reflects the negative impact the current economy is expected to have on large new construction as well as the projected number of applications for firm gas service in CECONY's service territory. The decrease also reflects an expected increase in customers’ energy efficiency measures and electrification of space heating.
Steam
CECONY operates the largest steam distribution system in the United States by producing and delivering approximately 17,837 MMlb of steam annually to approximately 1,584 customers in parts of Manhattan.
In May 2020, CECONY's five-year forecast of average annual change in the peak steam demand in its service area at design conditions remained unchanged at approximately (0.4) percent (for 2021 to 2025).
Collective Bargaining Agreement
In June 2020, CECONY reached a four-year collective bargaining agreement with its largest union covering approximately 7,100 employees, effective June 21, 2020.
O&R
Electric
O&R and its utility subsidiary, Rockland Electric Company (RECO) (together referred to herein as O&R) provide electric service to approximately 0.3 million customers in southeastern New York and northern New Jersey, an approximately 1,300 square mile service area.
Gas
O&R delivers gas to over 0.1 million customers in southeastern New York.
In June 2020, O&R decreased its five-year forecast of average annual growth of the peak gas demand in its service area at design conditions from approximately 0.7 percent (for 2020 to 2024) to approximately 0.2 percent (for 2021 to 2025). The decrease reflects an expected increase in customers' energy efficiency measures and electrification of space heating.
Clean Energy Businesses
Con Edison Clean Energy Businesses, Inc., together with its subsidiaries, are referred to in this report as the Clean Energy Businesses. The Clean Energy Businesses develop, own and operate renewable and energy infrastructure projects and provide energy-related products and services to wholesale and retail customers. In December 2018, the Clean Energy Businesses acquired Sempra Solar Holdings, LLC.
Con Edison Transmission
Con Edison Transmission, Inc. invests in electric and gas transmission projects through its wholly-owned subsidiaries, Consolidated Edison Transmission, LLC (CET Electric) and Con Edison Gas Pipeline and Storage, LLC (CET Gas). CET Electric owns a 45.7 percent interest in New York Transco LLC (NY Transco), which owns and has been selected to build additional electric transmission assets in New York. CET Gas owns, through subsidiaries, a 50 percent interest in Stagecoach Gas Services, LLC, a joint venture that owns and operates an existing gas pipeline and storage business located in northern Pennsylvania and southern New York. Also, CET Gas and
48

CECONY own 71.2 percent and 28.8 percent interests, respectively, in Honeoye Storage Corporation, which owns and operates a gas storage facility in upstate New York. In addition, CET Gas owns a 12.1 percent interest (that is expected to be reduced below 10 percent based on the current project cost estimate) in Mountain Valley Pipeline LLC, a joint venture developing a proposed 300-mile gas transmission project in West Virginia and Virginia. Con Edison Transmission, Inc., together with CET Electric and CET Gas, are referred to in this report as Con Edison Transmission.

Coronavirus Disease 2019 (COVID-19) Impacts
The Companies continue to respond to the Coronavirus Disease 2019 (COVID-19) global pandemic by reducing the potential risks posed to employees, customers and other stakeholders by its spread. The Companies continue to employ an incident command structure led by a pandemic planning team. The Companies support employee and facility hygiene through mandatory pre-entry symptom surveys for employees arriving at critical locations, regular cleaning and disinfecting of all work and common areas, promoting social distancing, imposing travel limitations on employees and directing employees to work remotely whenever possible. Employees who test positive for COVID-19 are directed to quarantine at home and are closely evaluated for close, prolonged contact with other employees that would require those employees to quarantine at home and, following the Centers for Disease Control and Prevention guidelines, sick or quarantined employees return to work when they can safely do so. The Utilities continue to provide critical electric, gas and steam service to customers during the pandemic. Additional safety protocols have been implemented to protect employees, customers and the public, when work at customer premises is required.
Below is additional information related to the effects of the COVID-19 pandemic and the Companies’ actions.
New York State Regulation
In March 2020, New York State Governor Cuomo declared a State Disaster Emergency for the State of New York, due to the COVID-19 pandemic and signed the "New York State on PAUSE" executive order that closed all non-essential businesses statewide. New York State designated utilities, including CECONY and O&R, as essential businesses that were able to continue a portion of their work during the effectiveness of the PAUSE order. In May 2020, the "New York Forward" plan went into effect. New York Forward is a phased plan to reopen businesses in geographic areas of New York State that meet metrics established by various public health organizations. Since the emergency declaration, and due to economic conditions, the NYSPSC and the Utilities have mitigated the potential impact of the COVID-19 pandemic on the Utilities, their customers and other stakeholders. See "COVID-19 Regulatory Matters" in Note B to the Second Quarter Financial Statements.
In March 2020, the Utilities began suspending service disconnections, certain collection notices, final bill collection agency activity, new late payment charges and certain other fees for all customers. The Utilities also began providing payment extensions for all customers that were scheduled to be disconnected prior to the start of the COVID-19 pandemic. In June 2020, the state of New York enacted a law prohibiting New York utilities, including CECONY and O&R, from disconnecting residential customers during the COVID-19 state of emergency. In addition, such prohibition will apply for an additional 180 days after the state of emergency ends for residential customers
49

who have experienced a change in financial circumstances due to the COVID-19 pandemic. The law expires on March 31, 2021. For the three and six months ended June 30, 2020, the estimated foregone revenues that were not collected by the Utilities were approximately $20 million and $23 million, respectively, for CECONY and $1.2 million and $1.4 million, respectively, for O&R. Also in March 2020, the Utilities requested and the NYSPSC granted extensions to file their 2019 Earnings Adjustment Mechanisms (EAMs) reports, which were filed in July 2020. The earned EAM incentives of approximately $46 million and $3 million for CECONY and O&R, respectively, are expected to be recovered from customers over a twelve-month period beginning September 2020.
See "COVID-19 Regulatory Matters" in Note B and Note K to the Second Quarter Financial Statements.
As of June 30, 2020, CECONY deferred, for New York City residential customers, $9 million of higher summer generation capacity supply costs. CECONY estimates that a total of $58 million of higher supply costs will be deferred and expects to recover such costs from November 2020 through April 2021. Also in June 2020, the NYSPSC directed CECONY to implement a summer cooling credit program to help mitigate the cost of staying home and running air conditioning for health-vulnerable low-income customers due to the limited availability of public cooling facilities as a result of the COVID-19 social distancing measures. The NYSPSC further ordered that the estimated $70.6 million cost of the program will be recovered over five years, beginning in January 2021.
In June 2020, the NYSPSC established a generic proceeding on the impacts of the COVID-19 pandemic and sought comment on a variety of COVID-19 related issues. In July 2020, the Utilities submitted joint comments with other large utilities in New York State that included a formal request to defer all COVID-19 related costs and for a surcharge mechanism to collect such deferrals based upon the individual utility's need.
The Utilities’ rate plans have revenue decoupling mechanisms in their New York electric and gas businesses that reconcile actual energy delivery revenues to the authorized delivery revenues approved by the NYSPSC. See "COVID-19 Regulatory Matters" in Note B to the Second Quarter Financial Statements and “Liquidity and Financing,” below.
New Jersey State Regulation
In March 2020, New Jersey Governor Murphy declared a Public Health Emergency and State of Emergency for the State of New Jersey. Since that declaration, the NJBPU and RECO have mitigated the potential impact of the COVID-19 pandemic on RECO, its customers and other stakeholders. New Jersey designated utilities, including RECO, as essential businesses that were able to continue a portion of their work. RECO modified or suspended certain work in the state. In March 2020, RECO began suspending late payment charges, terminations for non-payment, and no access fees during the COVID-19 pandemic. The suspension of these fees is not expected to be material. See "COVID-19 Regulatory Matters" in Note B and Note K to the Second Quarter Financial Statements.
In July 2020, the NJBPU authorized RECO and other New Jersey utilities to create a COVID-19-related regulatory asset by deferring prudently incurred incremental costs related to COVID-19 beginning on March 9, 2020, and through the later of September 30, 2021, or 60 days after the emergency declaration is no longer in effect. As of June 30, 2020, RECO had not yet deferred any incremental costs related to COVID-19 and such costs are not expected to be material.
Federal Regulation
In March 2020, the North American Electric Reliability Corporation (NERC) issued guidance that the effects of the COVID-19 pandemic will be considered an acceptable basis for non-compliance with certain NERC Reliability Standards requirements that would have required action between March 1, 2020 and July 31, 2020. In addition, it suspended on-site NERC compliance audits until at least July 31, 2020.
Also in March 2020, FERC announced several actions to ease regulatory obligations in response to the COVID-19 pandemic. These include postponement of certain filing deadlines and the suspension of all audit site visits and investigative testimony.
In April 2020, FERC announced it would expeditiously review and act on requests for relief in response to the COVID-19 pandemic, give priority to processing filings that contribute to the business continuity of regulated entities’ energy infrastructure and exercise prosecutorial discretion when addressing events arising during the COVID-19 pandemic. FERC also approved a blanket waiver of requirements in Open Access Transmission Tariffs that require entities to hold meetings in-person and to provide or obtain notarized documents. See "COVID-19 Regulatory Matters" in Note B” to the Second Quarter Financial Statements.

Gas Safety
In March 2020, the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) issued a notice staying enforcement of certain federal operator qualification, control room management and drug testing requirements during the COVID-19 pandemic. The notice also announced that PHMSA would exercise discretion in its overall enforcement of other parts of the pipeline safety regulations. The NYSPSC also provided guidance that it was staying enforcement of many of the same pipeline safety requirements identified in the March 2020 PHMSA notice.
In April 2020, the NYSPSC issued an order that extended the deadlines to complete certain gas inspections by all New York gas utilities, including CECONY and O&R, from April 1, 2020 to August 1, 2020. See "COVID-19 Regulatory Matters" in Note B to the Second Quarter Financial Statements.
Impact of CARES Act on Accounting for Income Taxes
In response to the economic impacts of the COVID-19 pandemic, the Coronavirus Aid, Relief, and Economic Security (CARES) Act became law on March 27, 2020. The CARES Act has several key business tax relief measures that may present potential cash benefits and/or refund opportunities for Con Edison and its subsidiaries, including permitting a five-year carryback of a net operating loss (NOL) for tax years 2018, 2019 and 2020, temporary removal of the 80 percent limitation of NOL carryforwards against taxable income for tax years before 2021, temporary relaxation of the limitations on interest deductions, Employee Retention Credit and defer payments of employer payroll taxes.
Con Edison will carryback its NOL of $29 million from tax year 2018 back to tax year 2013. This will allow Con Edison, mostly at the Clean Energy Businesses, to receive a $2.5 million net tax refund and to recognize a discrete income tax benefit of $4 million in March 2020, due to the higher federal tax rate in 2013. See Note J to the Second Quarter Financial Statements. Con Edison and its subsidiaries are not expecting to have a federal NOL in tax years 2019 or 2020.
Con Edison and its subsidiaries expect to benefit by the increase in the percentage for calculating the limitation on the interest expense deduction from 30 percent of Adjusted Taxable Income (ATI) to 50 percent of ATI in 2019 and 2020, which may allow the Companies to deduct 100 percent of interest expense.
The Companies qualify for an Employee Retention Tax Credit created under the CARES Act for "eligible employers" related to governmental authorities imposing restrictions that partially suspended their operations for a portion of their workforce due to the COVID-19 pandemic and the Companies continued to pay them. In the second quarter of 2020, Con Edison and CECONY recognized a tax benefit to Taxes, other than income taxes expense of $8 million and $5 million, respectively.
The CARES Act also allows employers to defer payments of the employer share of Social Security payroll taxes that would have otherwise been owed from March 27, 2020 through December 31, 2020. The Companies intend to defer the payment of employer payroll taxes for the period April 1, 2020 through December 31, 2020 of approximately $73 million ($65 million of which is for CECONY). The Companies will repay one-half of this liability by December 31, 2021 and the other half by December 31, 2022.
Supply Chain Matters
The Utilities continue to procure the materials and services necessary to support the phased plan to reopen businesses in New York State, which includes building an inventory of pandemic-related materials to address anticipated future needs. They maintain regular communications with key suppliers. There are currently no significant supply chain-related shortages or issues.
The Clean Energy Businesses have appropriate assets available to them and currently do not anticipate constraints in completing and placing into service wind and solar projects currently under construction.
Cybersecurity
In April 2020, the United States Homeland Security Cybersecurity and Infrastructure Security Agency issued a joint alert with another agency stating that there has been a growing use of COVID-19 related themes by malicious cyber actors and the surge in teleworking has increased the use of potentially vulnerable services, amplifying the threat to individuals and organizations. The Companies, their contractors and vendors have experienced cyber threats, but
51

none have had a material impact on the Companies. The Companies continue to monitor cybersecurity threats closely.
Accounting Considerations
As a result of the COVID-19 pandemic, both commercial and residential customers may have increased difficulty paying their utility bills, as a result of a decline in business, bankruptcies, layoffs and furloughs, among other factors. CECONY and O&R have existing allowances for uncollectible accounts established against their customer accounts receivable balances which are reevaluated each quarter and updated accordingly. Changes to the Utilities’ reserve balances that result in write-offs of customer accounts receivable balances are not reflected in rates during the term of the current rate plans. During the first six months of 2020, the potential economic impact of the COVID-19 pandemic was also considered in forward-looking projections related to write-off and recovery rates, resulting in increases to the customer allowance for uncollectible accounts as detailed herein. CECONY’s and O&R’s allowances for uncollectible accounts reserve increased from $65 million and $4.6 million at December 31, 2019 to $81 million and $6.0 million at June 30, 2020, respectively. See Note A to the Second Quarter Financial Statements.
The Companies test goodwill for impairment at least annually or whenever there is a triggering event, and test long-lived and intangible assets for recoverability when events or changes in circumstances indicate that the carrying value of long-lived or intangible assets may not be recoverable. The Companies identified no triggering events or changes in circumstances related to the COVID-19 pandemic that would indicate that the carrying value of long-lived or intangible assets may not be recoverable at June 30, 2020. See Note A to the Second Quarter Financial Statements.
Liquidity and Financing
The Companies continue to monitor the impacts of the COVID-19 pandemic on the financial markets closely, including borrowing rates and daily cash collections. The Companies have been able to issue commercial paper as needed since the start of the COVID-19 pandemic in March 2020. See Note D to the Second Quarter Financial Statements.
In addition, the decline in business activity in the Utilities’ service territory as a result of the COVID-19 pandemic has resulted in lower billed sales revenues and may continue to do so. The Utilities’ rate plans have revenue decoupling mechanisms in their New York electric and gas businesses that reconcile actual energy delivery revenues to the authorized delivery revenues approved by the NYSPSC per month and accumulate the deferred balances semi-annually under CECONY's electric rate plan (January through June and July through December, respectively) and annually under CECONY's gas rate plan and O&R New York's electric and gas rate plans (January through December). Differences are accrued with interest each month for CECONY and O&R New York’s electric customers and after the annual deferral period ends for CECONY and O&R New York’s gas customers for refund to, or recovery from customers, as applicable. Generally, the refund to or recovery from customers begins August and February of each year over an ensuing six-month period for CECONY's electric customers and February of each year over an ensuing twelve-month period for CECONY's gas and O&R New York's electric and gas customers. Although these revenue decoupling mechanisms are in place, lower billed sales revenues and higher uncollectible accounts would temporarily reduce liquidity at the Utilities. See Note A to the Second Quarter Financial Statements and "COVID-19 Regulatory Matters" in Note B to the Second Quarter Financial Statements.
In July 2020, Con Edison borrowed $820 million pursuant to an April 2020 credit agreement that was amended in June 2020 (as amended, the Supplemental Credit Agreement). Con Edison used the proceeds from the borrowing for general corporate purposes, including repayment of short-term debt bearing interest at variable rates. Pursuant to the Supplemental Credit Agreement, the borrowing bears interest at a variable rate and was converted to a term loan, that matures on March 29, 2021. See Note D to the Second Quarter Financial Statements.
Con Edison and the Utilities also have a $2,250 million credit agreement (Credit Agreement) in place under which banks are committed to provide loans on a revolving credit basis until December 2023 ($2,200 million of commitments from December 2022). Con Edison and the Utilities have not entered into any loans under the Credit Agreement. See Note D to the Second Quarter Financial Statements.

70

Other Income (Deductions)
Other income (deductions) decreased $78 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to higher costs associated with components of pension and other postretirement benefits other than service cost ($70 million) due to a decrease in the discount rate and the absence of the company’s share of a gain on sale of property in 2019 ($5 million).
Net Interest Expense
Net interest expense increased $8 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to higher interest on long-term debt ($23 million), offset in part by a decrease in interest accrued on the TCJA related regulatory liability ($6 million), lower interest expense for short-term debt ($4 million) and lower interest accrued on the system benefit charge liability ($4 million).
Income Tax Expense
Income taxes decreased $49 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to lower income before income tax expense ($12 million), an increase in the amortization of excess deferred federal income taxes due to CECONY’s new rate plan beginning in the first quarter of 2020 ($49 million) and higher flow-through tax benefits on plant-related items ($8 million), offset in part by the absence of the amortization of excess deferred state income taxes ($10 million), higher cost of removal expenses ($8 million), and higher allowance for uncollectible accounts ($3 million).

(a) | Revenues from New York gas sales are subject to a weather normalization clause and a revenue decoupling mechanism as a result of which delivery revenues are generally not affected by changes in delivery volumes from levels assumed when rates were approved.

(b) | After adjusting for weather and other variations, total firm sales and transportation volumes decreased 0.4 percent in the six months ended June 30, 2020 compared with 2019 period. See “Coronavirus Disease 2019 (COVID-19) Impacts,” above.

Operating revenues decreased $20 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to a decrease in gas purchased for resale ($24 million), offset in part by higher revenues from the New York gas rate plan ($2 million).
Gas purchased for resale decreased $24 million in the six months ended June 30, 2020 compared with the 2019 period due to lower unit costs ($18 million) and purchased volumes ($6 million).
Depreciation and amortization increased $1 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to higher gas utility plant balances.
Taxes, other than income taxes increased $1 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to higher property taxes.
Clean Energy Businesses
The Clean Energy Businesses’ results of operations for the six months ended June 30, 2020 compared with the 2019 period were as follows:

| For the Six Months Ended |
(Millions of Dollars) | June 30, 2020 | June 30, 2019 | Variation
Operating revenues | $344 | $450 | $(106)
Gas purchased for resale | 16 | 124 | (108)
Other operations and maintenance | 107 | 115 | (8)
Depreciation and amortization | 115 | 116 | (1)
Taxes, other than income taxes | 10 | 12 | (2)
Operating income | $96 | $83 | $13

Operating revenues decreased $106 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to lower wholesale revenues ($111 million) and lower energy services revenues ($17 million), offset in part by higher renewable electric production revenues ($20 million) and net mark-to-market values ($2 million).
Gas purchased for resale decreased $108 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to lower purchased volumes.
Other operations and maintenance expenses decreased $8 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to lower energy services costs.
73

Taxes, other than income taxes decreased $2 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to the Employee Retention Credit created under the CARES Act. See “Coronavirus Disease 2019 (COVID-19) Impacts - Impact of CARES Act on Accounting for Income Taxes,” above.
Net Interest Expense
Net interest expense increased $51 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to higher unrealized losses on interest rate swaps in the 2020 period.
Income Tax Expense
Income taxes decreased $11 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to lower income before income tax expense ($8 million), higher renewable energy credits ($2 million), lower state income taxes ($2 million) and a tax benefit due to the change in the federal corporate income tax rate recognized for a loss carryback from the 2018 tax year to the 2013 tax year as allowed under the CARES Act signed into law during the first quarter of 2020 ($4 million), offset in part by lower income attributable to non-controlling interest ($5 million).
Income Attributable to Non-Controlling Interest
Income attributable to non-controlling interest decreased $19 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to lower income attributable in the 2020 period to a tax equity investor in renewable electric production projects accounted for under the HLBV method of accounting. See Note O to the Second Quarter Financial Statements.
Con Edison Transmission
Income Tax Expense
Income taxes increased $2 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to higher income before income tax expense ($1 million) and higher state income taxes ($1 million).
Other
Income Tax Expense
Income taxes decreased $5 million in the six months ended June 30, 2020 compared with the 2019 period primarily due to lower state income taxes ($3 million) and the absence of an increase in uncertain tax positions in 2019 ($2 million).

Cash Flows from Operating Activities
The Utilities’ cash flows from operating activities primarily reflect their energy sales and deliveries and cost of operations. The volume of energy sales and deliveries is primarily affected by factors external to the Utilities, such as growth of customer demand, weather, market prices for energy and economic conditions. Measures that promote distributed energy resources, such as distributed generation, demand reduction and energy efficiency, also affect the volume of energy sales and deliveries. In addition, the decline in business activity in the Utilities’ service territory as a result of the COVID-19 pandemic has resulted and may continue to result in lower billed sales revenues. Under the revenue decoupling mechanisms in the Utilities’ New York electric and gas rate plans, changes in delivery volumes from levels assumed when rates were approved may affect the timing of cash flows, but generally not net income. The prices at which the Utilities provide energy to their customers are determined in accordance with their rate plans. In general, changes in the Utilities’ cost of purchased power, fuel and gas may affect the timing of cash flows, but not net income, because the costs are recovered in accordance with rate plans. Pursuant to their rate plans, the Utilities have recovered from customers a portion of the tax liability they will pay in the future as a result of temporary differences between the book and tax basis of assets and liabilities. These temporary differences affect the timing of cash flows, but not net income, as the Companies are required to record deferred tax assets and liabilities at the current corporate tax rate for the temporary differences. For the Utilities, credits to their customers of the net benefits of the TCJA, including the reduction of the corporate tax rate to 21 percent, decrease cash flows from operating activities. See “COVID-19 Regulatory Matters” and “Other Regulatory Matters” in Note B to the Second Quarter Financial Statements and “Coronavirus Disease 2019 (COVID-19) Impacts - Liquidity and Financing,” above.
Net income is the result of cash and non-cash (or accrual) transactions. Only cash transactions affect the Companies’ cash flows from operating activities. Principal non-cash charges or credits include depreciation, deferred income tax expense, amortizations of certain regulatory assets and liabilities, and accrued unbilled revenue. Non-cash charges or credits may also be accrued under the revenue decoupling and cost reconciliation mechanisms in the Utilities’ New York electric and gas rate plans.
Net cash flows from operating activities for the six months ended June 30, 2020 for Con Edison and CECONY were $358 million and $316 million lower, respectively, than in the 2019 period. The changes in net cash flows for Con Edison and CECONY primarily reflect higher accounts receivable balances from customers ($278 million and $249 million, respectively) (see “Coronavirus Disease 2019 (COVID-19) Impacts - Accounting Considerations” and “Liquidity and Financing,” above), lower other receivables and other current assets ($135 million and $98 million, respectively) primarily due to lower reimbursement received for Puerto Rico related restoration costs in the 2020 period, a change in pension and retiree benefit obligations ($68 million and $63 million, respectively) and lower system benefit charge ($45 million and $44 million, respectively), offset in part by lower TCJA net benefits provided to customers in the 2020 period ($147 million and $147 million, respectively).
The change in net cash flows also reflects the timing of payments for and recovery of energy costs. This timing is reflected within changes to accounts receivable – customers and recoverable and refundable energy costs within other regulatory assets and liabilities and accounts payable balances.
Cash Flows Used in Investing Activities
Net cash flows used in investing activities for Con Edison and CECONY were $56 million higher and $17 million lower, respectively, for the six months ended June 30, 2020 compared with the 2019 period. The change for Con Edison primarily reflects an increase in non-utility construction expenditures at the Clean Energy Businesses ($166 million) and the proceeds from the sale of a property formerly used by CECONY in its operations in 2019 ($48 million), offset in part by lower investments in electric and gas transmission projects at Con Edison Transmission in the 2020 period ($73 million) and a decrease in utility construction expenditures at CECONY ($66 million) and O&R ($19 million).
Cash Flows from Financing Activities
Net cash flows from financing activities for Con Edison and CECONY were $578 million and $494 million higher, respectively, in the six months ended June 30, 2020 compared with the 2019 period.
In July 2020, Con Edison borrowed $820 million pursuant to an April 2020 credit agreement that was amended in June 2020 (as amended, the Supplemental Credit Agreement). Con Edison used the proceeds from the borrowing
76

for general corporate purposes, including repayment of short-term debt bearing interest at variable rates. See Note D to the Second Quarter Financial Statements.
In May 2019, Con Edison entered into a forward sale agreement relating to 5,800,000 shares of its common stock. In June 2019, the company issued 4,750,000 shares for $400 million upon physical settlement of shares subject to the forward sale agreement and in January 2020, Con Edison issued 1,050,000 shares of its common stock for $88 million upon physical settlement of the remaining shares subject to its May 2019 forward sale agreement. Con Edison used the proceeds to invest in CECONY for funding of its capital requirements and other general corporate purposes. See Note C to the Second Quarter Financial Statements.
In March 2019, Con Edison issued 5,649,369 shares of its common stock for $425 million upon physical settlement of the remaining shares subject to its November 2018 forward sale agreements. Con Edison used the proceeds to invest in its subsidiaries for funding of their capital requirements and to repay short-term debt incurred for that purpose.
In February 2019, Con Edison borrowed $825 million under a two-year variable-rate term loan to fund the repayment of a six-month variable-rate term loan. In June 2019, Con Edison pre-paid $150 million of the amount borrowed.
In June 2020, CECONY redeemed at maturity $350 million of 4.45 percent 10-year debentures.
In March 2020, CECONY issued $600 million aggregate principal amount of 3.35 percent debentures, due 2030 and $1,000 million aggregate principal amount of 3.95 percent debentures, due 2050, the net proceeds from the sale of which will be used to pay or reimburse the payment of, in whole or in part, existing and new qualifying eligible green expenditures, such as energy efficiency and clean transportation expenditures, that include those funded on or after January 1, 2018 until the maturity date of each series of the debentures. Pending the allocation of the net proceeds to finance or refinance eligible green expenditures, CECONY used the net proceeds for repayment of short-term debt and temporarily placed the remaining net proceeds in short-term interest-bearing instruments. See Note C to the Second Quarter Financial Statements.
In May 2019, CECONY issued $700 million aggregate principal amount of 4.125 percent debentures, due 2049, the net proceeds from the sale of which were used to repay short-term borrowings and for other general corporate purposes.
In April 2019, CECONY redeemed at maturity $475 million of 6.65 percent 10-year debentures.
In May 2019, a Con Edison Development subsidiary borrowed $464 million, due 2026, secured by equity interests in solar electric production projects, the net proceeds from the sale of which were used to repay borrowings from Con Edison and for other general corporate purposes. Con Edison used a portion of the repayment to pre-pay $150 million of an $825 million two-year variable-rate term loan and the remainder to repay short-term borrowings and for other general corporate purposes.
Con Edison’s cash flows from financing for the six months ended June 30, 2020 and 2019 also reflect the proceeds, and reduction in cash used for reinvested dividends, resulting from the issuance of common shares under the company’s dividend reinvestment, stock purchase and long-term incentive plans of $52 million and $51 million, respectively.
Cash flows used in financing activities of the Companies also reflect commercial paper issuances and repayments. The commercial paper amounts outstanding at June 30, 2020 and 2019 and the average daily balances for the six months ended June 30, 2020 and 2019 for Con Edison and CECONY were as follows:

| 2020 | 2019
(Millions of Dollars, except Weighted Average Yield) | Outstanding at June 30, | Daily average | Outstanding at June 30, | Daily average
Con Edison | $1,813 | $1,117 | $1,161 | $1,111

The agreement between Crestwood and Con Edison Gas Pipeline and Storage, LLC (CET Gas) provides for payments from Crestwood to CET Gas for shortfalls in meeting certain earnings growth performance targets. The payment is expected to total $57 million ($19 million of which is due in the first quarter 2021 and was recorded as a receivable by CET in March 2020, with an additional $19 million plus interest due in each of January 2022 and January 2023). See "Con Edison Transmission" below.
Investments at June 30, 2020 were $2 million higher than at December 31, 2019. The change in investments primarily reflects increased allowance for funds used during construction (AFUDC) income from Mountain Valley Pipeline, LLC ($29 million) and investment income from NY Transco ($4 million), offset in part by investment income less partnership distribution from Stagecoach Services ($12 million) and the decrease in CET Gas' investment in Stagecoach Gas Services, LLC due to the receivable from Crestwood described above ($19 million).
Equity at June 30, 2020 was $22 million higher than at December 31, 2019. The change in equity primarily reflects net income for the six months ended June 30, 2020 ($28 million), offset in part by common stock dividends to parent ($6 million) in 2020.
Off-Balance Sheet Arrangements
At June 30, 2020, none of the Companies’ transactions, agreements or other contractual arrangements meet the SEC definition of off-balance sheet arrangements.

Total | 2,172 | 2,042 | 130 | 6.4 | % | 3,677 | 3,393 | 284 | 8.4 | %

Con Edison Transmission
CET Gas
In June 2020, the operator of the Mountain Valley Pipeline, which is being constructed by a joint venture in which CET Gas has a 12.1 percent ownership interest (that is expected to be reduced below 10 percent based on the current project cost estimate), indicated that it now expects an early 2021 full in-service date for the project. The operator indicated that total project costs may potentially increase approximately 5% above the project’s $5,400 million estimate, excluding AFUDC. At June 30, 2020, CET Gas’s cash contributions to the joint venture amounted to $530 million.
Financial and Commodity Market Risks
The Companies are subject to various risks and uncertainties associated with financial and commodity markets. The most significant market risks include interest rate risk, commodity price risk and investment risk.
Interest Rate Risk
The Companies’ interest rate risk primarily relates to new debt financing needed to fund capital requirements, including the construction expenditures of the Utilities and maturing debt securities, and variable-rate debt. Con Edison and its subsidiaries manage interest rate risk through the issuance of mostly fixed-rate debt with varying maturities and through opportunistic refinancing of debt. The Clean Energy Businesses use interest rate swaps to exchange variable-rate project financed debt for a fixed interest rate. See Note M to the Second Quarter Financial Statements. Con Edison and CECONY estimate that at June 30, 2020, a 10 percent increase in interest rates applicable to its variable rate debt would result in an increase in annual interest expense of $1 million. Under CECONY’s current electric, gas and steam rate plans, variations in actual variable rate tax-exempt debt interest expense, including costs associated with the refinancing of the variable-rate tax-exempt debt, are reconciled to levels reflected in rates.
Commodity Price Risk
Con Edison’s commodity price risk primarily relates to the purchase and sale of electricity, gas and related derivative instruments. The Utilities and the Clean Energy Businesses apply risk management strategies to mitigate their related exposures. See Note M to the Second Quarter Financial Statements.
Con Edison estimates that, as of June 30, 2020, a 10 percent decline in market prices would result in a decline in fair value of $89 million for the derivative instruments used by the Utilities to hedge purchases of electricity and gas, of which $84 million is for CECONY and $5 million is for O&R. Con Edison expects that any such change in fair value would be largely offset by directionally opposite changes in the cost of the electricity and gas purchased. In accordance with provisions approved by state regulators, the Utilities generally recover from customers the costs they incur for energy purchased for their customers, including gains and losses on certain derivative instruments used to hedge energy purchased and related costs.
83

The Clean Energy Businesses use a value-at-risk (VaR) model to assess the market price risk of their portfolio of electricity and gas commodity fixed-price purchase and sales commitments, physical forward contracts, generating assets and commodity derivative instruments. VaR represents the potential change in fair value of the portfolio due to changes in market prices, for a specified time period and confidence level. These businesses estimate VaR across their portfolio using a delta-normal variance/covariance model with a 95 percent confidence level, compare the measured VaR results against performance due to actual prices and stress test the portfolio each quarter using an assumed 30 percent price change from forecast. Since the VaR calculation involves complex methodologies and estimates and assumptions that are based on past experience, it is not necessarily indicative of future results. VaR for the portfolio, assuming a one-day holding period, for the six months ended June 30, 2020 and the year ended December 31, 2019, respectively, was as follows:

95% Confidence Level, One-Day Holding Period | June 30, 2020 |  | December 31, 2019 |
| (Millions of Dollars)
Average for the period |  | $— |  |  | $— |
High | — |  | 1 |
Low | — |  | — |

Investment Risk
The Companies’ investment risk relates to the investment of plan assets for their pension and other postretirement benefit plans and to the investments of Con Edison Transmission that are accounted for under the equity method.
The Companies’ current investment policy for pension plan assets includes investment targets of 45 to 55 percent equity securities, 33 to 43 percent debt securities and 10 to 14 percent real estate. At June 30, 2020, the pension plan investments consisted of 50 percent equity securities, 38 percent debt securities and 12 percent real estate.
For the Utilities’ pension and other postretirement benefit plans, regulatory accounting treatment is generally applied in accordance with the accounting rules for regulated operations. In accordance with the Statement of Policy issued by the NYSPSC and its current electric, gas and steam rate plans, CECONY defers for payment to or recovery from customers the difference between the pension and other postretirement benefit expenses and the amounts for such expenses reflected in rates. O&R also defers such difference pursuant to its New York rate plans.
Material Contingencies
For information concerning potential liabilities arising from the Companies’ material contingencies, see "Other Regulatory Matters" in Note B and Notes G and H to the Second Quarter Financial Statements.

Item 3: Quantitative and Qualitative Disclosures About Market Risk
For information about the Companies’ primary market risks associated with activities in derivative financial instruments, other financial instruments and derivative commodity instruments, see “Financial and Commodity Market Risks,” in Part I, Item 2 of this report, which information is incorporated herein by reference.
Item 4: Controls and Procedures
The Companies maintain disclosure controls and procedures designed to provide reasonable assurance that the information required to be disclosed in the reports that they submit to the Securities and Exchange Commission (SEC) is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. For each of the Companies, its management, with the participation of its principal executive officer and principal financial officer, has evaluated its disclosure controls and procedures as of the end of the period covered by this report and, based on such evaluation, has concluded that the controls and procedures are effective to provide such reasonable assurance. Reasonable assurance is not absolute assurance, however, and there can be no assurance that any design of controls or procedures would be effective under all potential future conditions, regardless of how remote.
There was no change in the Companies’ internal control over financial reporting that occurred during the Companies’ most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Companies’ internal control over financial reporting.

Part II Other Information
Item 1: Legal Proceedings
For information about certain legal proceedings affecting the Companies, see "Other Regulatory Matters" in Note B and Notes G and H to the financial statements in Part I, Item 1 of this report, which information is incorporated herein by reference.
Item 1A: Risk Factors
Please see below the new risk factor affecting the Companies’ businesses, in addition to those discussed in Item 1A of the Form 10-K.
We face risks related to health epidemics and other outbreaks, including the COVID-19 pandemic.
The COVID-19 pandemic is currently impacting countries, communities, supply chains and markets. In the second quarter, our service territories included some of the most severely impacted counties in the United States. As a result of the COVID-19 pandemic, we may face an extended economic slowdown in our service territories that could have a material impact on our liquidity, financial condition, and results of operations.
We will continue to monitor developments relating to the COVID-19 pandemic; however, we cannot predict the extent to which COVID-19 may have a material impact on our business operations, liquidity, financial condition, and results of operations. The extent to which COVID-19 may impact these matters will depend on future developments that are highly uncertain and cannot be predicted, including new information concerning the severity of COVID-19, actions that federal, state and local governmental or regulatory agencies may take in response to COVID-19, and other actions taken to contain it or treat its impact, among others. See “Coronavirus Disease 2019 (COVID-19) Impacts” in Item 2 and “COVID-19 Regulatory Matters” in Note B.
