NOTES TO CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

For the three months ended March 31, 2020 and 2019

1.    DESCRIPTION OF THE BUSINESS

Hydro One Limited (Hydro One or the Company) was incorporated on August 31, 2015, under the Business Corporations Act (Ontario). On October 31, 2015, the Company acquired Hydro One Inc., a company previously wholly-owned by the Province of Ontario (Province). The acquisition of Hydro One Inc. by Hydro One was accounted for as a common control transaction and Hydro One is a continuation of business operations of Hydro One Inc. At March 31, 2020, the Province held approximately 47.3% (December 2019 - 47.3%) of the common shares of Hydro One. The principal businesses of Hydro One are the transmission and distribution of electricity to customers within Ontario.

Earnings for interim periods may not be indicative of results for the year due to the impact of seasonal weather conditions on customer demand and market pricing.

Rate Setting

The Company's transmission business consists of the transmission system operated by subsidiaries of Hydro One Inc., Hydro One Networks Inc. (Hydro One Networks) and Hydro One Sault Ste. Marie LP (HOSSM), as well as an approximately 66% interest in B2M Limited Partnership (B2M LP), a limited partnership between Hydro One and the Saugeen Ojibway Nation (SON), and an approximately 55% interest in Niagara Reinforcement Limited Partnership (NRLP), a limited partnership between Hydro One and Six Nations of the Grand River Development Corporation and the Mississaugas of the Credit First Nation (collectively, the First Nations Partners). Hydro One’s distribution business consists of the distribution system operated by Hydro One Inc.'s subsidiaries, Hydro One Networks and Hydro One Remote Communities Inc. (Hydro One Remote Communities).

Transmission

On March 21, 2019, Hydro One Networks filed a three-year Custom Incentive Rate application with theOntario Energy Board (OEB) for 2020-2022 transmission rates.On December 10, 2019, the OEB approved Hydro One Networks' 2019 transmission revenue requirement and charges as interim effective January 1, 2020 until the new transmission revenue requirement and charges are approved by the OEB.On April 23, 2020, the OEB rendered its decision on the 2020-2022 transmission rate application. See Note 28 - Subsequent Events for additional information.

On July 31, 2019, B2M LP filed a transmission rate application for 2020-2024, seeking a base revenue requirement of $36 million for 2020, and a revenue cap escalator index for 2021 to 2024. On January 16, 2020, the OEB approved an updated 2020 base revenue requirement of $33 million, and the revenue cap escalator index for 2021 to 2024.

On December 17, 2019, the OEB issued a decision on HOSSM’s request for transmission revenue requirement for 2020. The OEB approved a 1.5% revenue cap increase effective January 1, 2020.

On October 25, 2019, NRLP filed its revenue cap incentive rate application for 2020-2024. On December 19, 2019, the OEB approved NRLP’s proposed 2020 revenue requirement of $9 million on an interim basis effective January 1, 2020.On April 9, 2020, final OEB approval was received.

Distribution

On November 15, 2019, Hydro One Remote Communities filed an application with the OEB seeking approval for a 2% increase to 2019 base rates. On April 16, 2020, the OEB approved the requested increase for new rates effective May 1, 2020, while the implementation of these rates will be deferred to November 1, 2020 due to COVID-19.

COVID-19 Emergency Deferral

On March 25, 2020, the OEB issued accounting guidance for the establishment of three deferral accounts to track incremental costs and lost revenues related to the COVID-19 pandemic: (i) Billing and System Changes as a Result of the Emergency Order Regarding Time-of-Use Pricing, (ii) Lost Revenues Arising from the COVID-19 Emergency, and (iii) Other Incremental Costs, including costs relating to bad debt expenses. The OEB accounting guidance specified that incremental bad debt expense can be included in the Other Incremental Costs COVID-19 emergency deferral account and the Company has assessed that it is probable that this expense will be recovered in future rates; therefore, this has been recognized as a regulatory asset. The current balance in the deferral account represents the incremental bad debt expense as a result of the COVID-19 pandemic. Hydro One is also tracking certain incremental costs and lost revenues that have arisen due to the COVID-19 pandemic. These amounts have not been recognized as regulatory assets as the Company is currently assessing whether they are probable for recovery in future rates. The OEB intends to set out the timing and process for disposition of the deferral accounts.

Fair Value Measurements of Derivative Instruments

Fair Value Hedges

At March 31, 2020, Hydro One Inc. had interest-rate swaps with a total notional amount of $350 million (December 31, 2019 - $350 million) that were used to convert fixed-rate debt to floating-rate debt. These swaps are classified as fair value hedges. Hydro One Inc.’s fair value hedge exposure was approximately 3% (December 31, 2019 - 3%) of its total long-term debt. At March 31, 2020, Hydro One Inc. had the following interest-rate swaps designated as fair value hedges:

• a $50 million fixed-to-floating interest-rate swap agreement to convert $50 million of the $350 million MTN Series 33 notes maturing April 30, 2020 into three-month variable rate debt; and

• a $300 million fixed-to-floating interest-rate swap agreement to convert the $300 million MTN Series 39 notes maturing June 25, 2021 into three-month variable rate debt.

Cash Flow Hedges

At March 31, 2020, Hydro One Inc. had the following agreements designated as cash flow hedges:

• $800 million in 3-year pay-fixed, receive-floating interest-rate swap agreements intended to offset the variability of interest rates on the issuances of short-term commercial paper between January 9, 2020 and March 9, 2023; and

• $400 million of bond forward agreements intended to mitigate exposure to variability in interest rates on forecasted fixed-rate issuance from Hydro One Inc.'s MTN program, expected to occur by the end of 2020.

At March 31, 2020 and December 31, 2019, the Company had no derivative instruments classified as undesignated contracts.

Fair Value Hierarchy

The fair value hierarchy of financial assets and liabilities at March 31, 2020 and December 31, 2019 is as follows:

As at March 31, 2020 (millions of dollars)	Carrying Value	Fair  Value	Level 1	Level 2	Level 3
Assets:
Derivative instruments (Note 12)
Fair value hedges (interest-rate swaps)	6	6	—	6	—

Cash flow hedges, including current portion (interest-rate swaps)	25	25	—	25	—
	12,599	14,062	—	14,062	—

As at December 31, 2019 (millions of dollars)	Carrying Value	Fair  Value	Level 1	Level 2	Level 3

Long-term debt, including current portion	11,475	13,472	—	13,472	—
	11,475	13,472	—	13,472	—

The fair value of the hedged portion of the long-term debt is primarily based on the present value of future cash flows using a swap yield curve to determine the assumption for interest rates. The fair value of the unhedged portion of the long-term debt is based on unadjusted period-end market prices for the same or similar debt of the same remaining maturities.

Risk Management

Exposure to market risk, credit risk and liquidity risk arises in the normal course of the Company’s business.

Market Risk

Market risk refers primarily to the risk of loss which results from changes in costs, foreign exchange rates and interest rates. The Company is exposed to fluctuations in interest rates, as its regulated return on equity is derived using a formulaic approach that takes anticipated interest rates into account. The Company is not currently exposed to material commodity price risk or material foreign exchange risk.

The Company uses a combination of fixed and variable-rate debt to manage the mix of its debt portfolio. The Company also uses derivative financial instruments to manage interest-rate risk. The Company may utilize interest-rate swaps designated as fair value hedges as a means to manage its interest rate exposure to achieve a lower cost of debt. The Company may also utilize interest-rate derivative instruments, such as cash flow hedges, to manage its exposure to short-term interest rates or to lock in interest-rate levels in forecasted financing.

A hypothetical 100 basis points increase in interest rates associated with variable-rate debt would not have resulted in a significant decrease in Hydro One’s net income for the three months ended March 31, 2020 and 2019.

For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in the consolidated statements of operations and comprehensive income. The net unrealized loss (gain) on the hedged debt and the related interest-rate swaps for the three months ended March 31, 2020 and 2019 were not material.

For derivative instruments that are designated and qualify as cash flow hedges, the unrealized gain or loss, net of tax, on the derivative instrument is recorded as other comprehensive income (OCI) and is reclassified to results of operations in the same period during which the hedged transaction affects results of operations. The unrealized loss, net of tax, on the cash flow hedges for the three months ended March 31, 2020 recorded in OCI was $20 million (2019 - $nil), resulting in an accumulated other comprehensive loss of $18 million related to cash flow hedges at March 31, 2020 (December 31, 2019 - accumulated OCI of $2 million). No amounts were reclassified to results of operations during the three months ended March 31, 2020 or 2019. The Company estimates that the amount of accumulated other comprehensive loss, net of tax, related to cash flow hedges to be reclassified to results of operations in the next 12 months is approximately $5 million. Actual amounts reclassified to results of operations depend on the market risk in effect until the derivative contracts mature. For all forecasted transactions, the maximum term over which the Company is hedging exposures to the variability of cash flows is approximately three years.

Credit Risk

Financial assets create a risk that a counterparty will fail to discharge an obligation, causing a financial loss. At March 31, 2020 and December 31, 2019, there were no significant concentrations of credit risk with respect to any class of financial assets. The Company’s revenue is earned from a broad base of customers. As a result, Hydro One did not earn a material amount of revenue from any single customer. At March 31, 2020 and December 31, 2019, there was no material accounts receivable balance due from any single customer.

At March 31, 2020, the Company’s allowance for doubtful accounts was $38 million (December 31, 2019 - $22 million). The allowance for doubtful accounts reflects the Company's current lifetime expected credit losses for all accounts receivable balances, which are based on historical overdue balances, customer payments and write-offs. At March 31, 2020, approximately 5% (December 31, 2019 - 5%) of the Company’s net accounts receivable were outstanding for more than 60 days. Please see Note 8 - Accounts Receivable for additions to allowance for doubtful accounts related to the impact of the COVID-19 pandemic.

Hydro One manages its counterparty credit risk through various techniques including (i) entering into transactions with highly rated counterparties, (ii) limiting total exposure levels with individual counterparties, (iii) entering into master agreements which enable net settlement and the contractual right of offset, and (iv) monitoring the financial condition of counterparties. The Company monitors

current credit exposure to counterparties on both an individual and an aggregate basis. The Company’s credit risk for accounts receivable is limited to the carrying amounts on the consolidated balance sheets.

Derivative financial instruments result in exposure to credit risk since there is a risk of counterparty default. The maximum credit exposure of derivative contracts, before collateral, is represented by the fair value of contracts at the reporting date. At March 31, 2020 and December 31, 2019, the counterparty credit risk exposure on the fair value of these interest-rate swap contracts was not material. At March 31, 2020, Hydro One’s credit exposure for all derivative instruments, and applicable payables and receivables, was with four financial institutions with investment grade credit ratings as counterparties.

Liquidity Risk

Liquidity risk refers to the Company’s ability to meet its financial obligations as they come due. Hydro One meets its short-term operating liquidity requirements using cash and cash equivalents on hand, funds from operations, the issuance of commercial paper, and the Operating Credit Facilities. The short-term liquidity under the commercial paper program, the Operating Credit Facilities, available cash on hand, and anticipated levels of funds from operations are expected to be sufficient to fund the Company’s operating requirements and debt maturities in 2020. The Company's currently available liquidity is also expected to be sufficient to address any reasonably foreseeable impacts that the COVID-19 pandemic may have on the Company’s cash requirements in 2020.

On June 18, 2018, Hydro One filed a short form base shelf prospectus (Universal Base Shelf Prospectus) with securities regulatory authorities in Canada. The Universal Base Shelf Prospectus allows Hydro One to offer, from time to time in one or more public offerings, up to $4.0 billion of debt, equity or other securities, or any combination thereof, during the 25-month period ending on July 18, 2020. On November 23, 2018, HOHL filed a short form base shelf prospectus (US Debt Shelf Prospectus) with securities regulatory authorities in Canada and the US. The US Debt Shelf Prospectus allows HOHL to offer, from time to time in one or more public offerings, up to US$3.0 billion of debt securities, unconditionally guaranteed by Hydro One, during the 25-month period ending on December 23, 2020. At March 31, 2020, no securities have been issued under the Universal Base Shelf Prospectus or the US Debt Shelf Prospectus.

²  The Company accounts for pension costs consistent with their inclusion in OEB-approved rates. During the three months ended March 31, 2020, pension costs of $19 million (2019 - $19 million) were attributed to labour, of which $7 million (2019 - $8 million) was charged to operations, $nil (2019 - $5 million) was recorded as regulatory assets, and $12 million (2019 - $6 million) was capitalized as part of the cost of property, plant and equipment and intangible assets.

Effective March1, 2018, certain employees who provided customer service operations for Hydro One through Inergi LP were transferred to Hydro One Networks, and began accruing defined benefits in the Hydro One defined benefit pension plan (Pension Plan). Pursuant to the arrangement, Inergi LP, Vertex Customer Management (Canada) Ltd. and Hydro One Networks agreed to transfer the defined benefit assets and related pension obligations (for current and former members) of the Inergi LP Customer Service Operations Pension Plan and the Vertex Customer Management (Canada) Limited Pension Plan (Transferring Plans) to the Pension Plan, effective March 1, 2018. Regulatory approval for the transfer was received on November 27, 2019 and the assets and related pension obligations of the Transferring Plans were transferred to the Pension Plan on March 2, 2020.
