There is no ossuronce thot the OEB would ollow rote increoses sufficient lo offset unfovouroble finonciol impocts from unonticipoted chonges in electricify demond or in the Compony's cosls. The Compony is subiect to risk of revenue loss from other foctors, such os economic trends ond weother conditions thot influence the demond for electricity. The Compony's overoll operoting results moy flucluote subslontiolly on o seosonol ond yeor-loyeor bosis bosed on these trends ond weother conditions. For instonce, o cooler thon normol summer or wormer lhon normol winter moy reduce demond for eleckicity below thot forecost by the Compony, cousing o decreose in the Compony's revenues from the some period of the previous yeor. The Compony's lood could olso be negotively offmted by successful Conservotion ond Demond Monogement progroms whose results exceed forecosted expectotions. R;sks Re/oting lo Rote-Seltin g Models for T ronsmission ond Di slribution The OEB opproves ond periodicolly chonges the ROE for tronsmission ond distribution buslnesses. The OEB moy in the fulure decide to reduce the ollowed ROE for either of these businesses, modify the lormulo or methodology it uses to delermine the ROE, or reduce the weighting ol the equity component of the deemed copitol struclure. Any such reduclion could reduce the net income of the Compony. The OEB's recent Custom Incentive Rote-setfing model requires thol the term of o custom rote opplicotion be o minimum fiveyeor period. There ore risks ossocioted with forecosling key inputs such os revenues, operoting expenses ond copitol, over such o long period.

To the extent thot the OEB opproves on ln-Service Vorionce Account for the tronsmission ond,/or distribution businesses, ond should the Compony foil to meet the threshold levels of in-service copitol, the OEB moy recloim o corresponding portion o[ the Compony's revenues. Risks Re/otin g to Copitol Expenditures ln order to be recoveroble, copitol expendilures require the opprovol of the OEB, either through the opprovol of copitol expendlture plons, role bose or revenue requirements for the purposes of setting lronsmission ond distribution rotes, which include the impocl of copitol expendilures on rote bose or cost o[ servlce. There con be no ossuronce thot oll copitol expenditures incuned by Hydro One will G opproved by the OEB. Copitol cost overruns moy not be recoveroble in tronsmission or distribution rotes. The Compony could incur unexpected copitol expenditures in mointoining or improving its ossets, porliculorly given thot new technology moy be required to support renewoble generotion ond unloreseen technicol issues moy be identified through implementotion of proiects. There is risk thot the OEB moy not ollow full recovery of such expenditures in the future. To the extent possible, Hydro One oims to mitigote this risk by ensuring prudent expenditures, seeking from the regulotor cleor policy direction on cosl responsibility, ond preopprovol o[ the need for copitol expenditures. Any future regulotory decision by the OEB to disollow or limit the recovery o[ ony copitol expenditures would leod to o lower lhon expected opproved revenue requiremenl or role bose, potentiol osset impoirment or chorges to the Compony's results o[ operotions, ony of which could hove o moteriol odverse effect on the Compony. Risks Re/otin g to Deferred Tox Asset As o result of leoving the Pl[s Regime ond entering the Federol Tox Regime in connection with the IPO o[ the Compony, Hydro One recorded o deferred tox osset due to the revoluotion ol the tox bosis of Hydro One's fixed ossets ot their [oir morket volue ond recognition of eligible copitol expenditures. Monogement believes this will result in onnuol net cosh sovings over ot leost the next five yeors due to the reduclion o{ cosh income toxes poyoble by Hydro One ossocioted primorily with o higher copitol cost ollowonce. There is o risk thot, in current or future rote opplicotions, the OEB will reduce the Compony's revenue requirement by oll or o portion of those nel cosh sovings. lf the OEB were to reduce fie Compony's revenue requirement in this monner, it could hove o moteriol odverse elfect on the Compony.

To occupy Reserves, the Compony musl hove volid permits issued by Her Moiesly the Queen in the Right of Conodo. For eoch permit, the Compony must negotiote on ogreement (in the form o[ o memorondum ol understonding) with the First Notion, the Ontorio Electricify Finonciol Corporolion ond ony members of the First Notion who hove occuponcy rights. The ogreement includes provisions whereby the First Notion consents lo the federol government {presently lndigenous Af{oirs ond Noilhern Development Conodo) issuing o permit.

In either cose, the costs reloting to these ossets could hove o moteriol odverse effecl on the Compony if the costs ore not recoveroble in future rote orders. Complionce with Lows ond Regulotions Hydro One must comply with numerous lows ond regulotlons oflecting its business, including requirements reloting to tronsmission ond diskibution componies, environmentol lows, employment lows ond heolth ond sofe! lows. The foilure of the Compony to comply with these lows could hove o moteriol odverse effect on lhe Compony's business. See olso "- Heolth, Sofety ond Environmentol KISK. For exomple, Hydro One's licensed tronsmission ond distribution businesses ore required to comply with the terms of lheir licences, with codes ond rules lssued by the OEB, ond with olher regulotory requirements, including regulotions o[ the Notionol Energy Boord. In Ontorio, the Morket Rules issued by the IESO require the Compony to, omong other things, comply with the reliobility stondords estoblished by the North Americon Electric Reliobility Corporolion (NERC) ond Northeost Power Coordinoting Council, lnc. (NPCC). The incrementol costs ossocioted wilh complionce with these reliobility stondords ore expected to be recovered through rotes, but there con be no ossuronce thot the OEB will opprove the recovery of oll of such incrementol costs. Foilure to obtoin such opprovols could hove o moteriol odverse effect on the Compony. There is the risk thol new legislotion, regulotions, requiremenls or policies will be introduced in the future. These moy require Hydro One to incur odditionol costs, which moy or moy not be recovered in future tronsmission ond distribution roles. Risk of Noturol ond Other Unexpected Occurrences The Compony's focilities ore exposed to the eflects of severe weother conditions, noturol disosters, mon-mode events including but not limited lo cyber ond physicol terrorist type ottocks, events which originote from third-porty connected systems, or ony olher potentiolly cotostrophic events. The Compony's focilities moy not withstond occurrences of thls type in oll circumslonces.

Losses from lost revenues ond repoir costs could be substontiol, especiolly for mony of the Compony's focilities thot ore locoted in remole oreos. The Compony could olso be subiect to cloims for domoges coused by its foilure to tronsmit or distribute electricity. Risk Associoted with lnformotion Technology lnfroslructure ond Doto Security The Compony's obilily to operole effectively in the Ontorio eleckicity morket is, in port, dependent upon it developing, mointoining ond monoging complex informolion technology systems which ore employed to operote ond monitor its tronsmission ond distribution focilities, [inonciol ond billing systems ond olher business systems. The Compony's increosing relionce on informotion syslems ond exponding doto nelworks increoses ils exposure to informotion security threots. The Compony's lronsmission business is required to comply with vorious rules ond slondords for tronsmission reliobility, including mondotory stondords estoblished by the NERC ond the NPCC. These include stondords reloting to cyber-security ond informotion technology, which only opply to certoin of the Compony's ossets (generolly being those whose foilure could impoct the functioning of the bulk electricily system). The Compony moy mointoin different or lower levels o[ informotion technology security for its ossets thot ore not subiect to these mondotory stondords. The Compony must olso comply with legislotive ond licence requirements reloting to the collection, use ond disclosure o[ personol informotion ond informotion regording consumers, wholesolers, generotors ond retoilers.

Any such system [oilures or security breoches could hove o moteriol odverse effect on the Compony. Work Force Demogrophic Risk By the end o[ 2O16, opproximotely 22% ol the Compony's employees who ore members of the Compony's defined benefit pension plon were eligible for retirement under thot plon, ond by the end of 2017, up to opproximotely 23% could be eligible. These percentoges ore not evenly spreod ocross the Compony's work force, but tend to be most significont in the most senior levels of the Compony's stoff ond especiolly omong monogement stoff. During eoch of 20 I 6 ond 20 I 5, opproximotely 3% of the Compony's work force elected lo retire. Accordingly, the Compony's conlinued success will be tied to its obility to conlinue to otlrocl ond retoin sufficient quolified stoff to reploce the copobility lost through retirements ond to meet the demonds of the Compony's work progroms. ln oddltion, the Compony expects the skilled lobour morket for its industry to be highly competitive in the future. Mony of the Compony's current employees ond mony o[ the potentiol employees it would seek in the future possess skills ond experience thot would olso be highly sought ofter by other orgonizotions inside ond outside the elmkicity sector. The foilure to otlrod ond retoin quolilied personnel for Hydro One's business could hove o moteriol odverse effed on the Compony. Lobour Relotions Risk The substontiol moiorl! of the Compony's employees ore represented by either the PWU or the Society. Over the post severol yeors, significont effort hos been expended to increose Hydro One's flexibility to conduct operotions in o more costefflcienl monner. Although the Compony hos ochieved improved flexibility in its collective ogreements, the Compony moy not be oble to ochieve furfier improvements. The Compony reoched on ogreemenl wilh the PWU for o renewol collective ogreement with o threeyeor term, covering the period from April l, 2015 to Morch 3,l, 20,l8 ond on eorly renewol collective ogreement wilh the Sociely with o threerTeor term, covering the period from April 1 , 2016 to Morch 3l , 2019. The Compony olso reoched o renewol collective ogreement with the Conodion Union of Skilled Workers for o three-yeor term, covering the period lrom Moy 1,2014 to April 30, 2012. Additionolly, the EPSCA ond o number o[ construction unions hove reoched renewol ogreements, to which Hydro One is bound, for o fiveyeor term, covering the period from Moy I , 2015 to April 30, 2020. Future negotiotions with unions presenl the risk of o lobour disruption ond the obilily lo sustoin lhe continued supply of energy to customers. The Compony olso foces finonciol risks reloted to its obility to negotiote collective ogreements consislent with its rote orders. ln oddition, in the event of o lobour dispute, the Compony could foce operotionol risk reloted to continued complionce with its requirements of providing service to customers. Any of these could hove o moteriol odverse effect on the Compony. Risk Associoted with Arronging Debt Finoncing The Compony expects to borrow to repoy its exisling indebtedness ond lo fund o portion of copitol expenditures. Hydro One lnc. hos substontiol debt principol repoyments, including $602 million in 2017,$753 milllon in 2018, ond $23 1 million in 2019. ln oddition, from time to time, the Compony moy drow on its syndicoted bonk lines ond or issue short-lerm debt under Hydro One lnc.'s $.l.5 billion commerciol poper progrorn which would moture withln opproximotely one yeor of issuonce. The Compony olso plons to incur conlinued moteriol copitol expendltures for eoch of 2017 ond 20 I B. Cosh generoled from operotions, ofter the poyment of expected dividends, will not be sufficient to lund the repoyment of the Compony's existing indebtedness ond copitol expenditures. The Compony's obility to ononge sufficient ond costeffective debt linoncing could be moteriolly odversely offected by numerous foclors, including the regulotory environment in Ontorio, the Compony's results of operotions ond finonciol position, morket conditions, the rotings ossigned to its debt securilies by credit roting ogencies, on inobility of the Corporotion to comply wilh its debt covenonts, ond generol economic conditions. A downgrode in the Compony's credit rotings could restrlct lhe Compony's obility to occess debl copltol morkets ond increose the Compony's cost o[ debt. Any loilure or inobility on the Compony's port to bonow the required omounts of debt on sotisfoctory terms could impoir its obillry to repoy moturing debt, fund copitol expenditures ond meet olher obligotions ond requirements qnd, os o result, could hove o moteriol odverse eflect on the Compony. Morket, Finonciol lnstrument ond Credit Risk Morket risk refers primorily to the risk o[ loss thot results from chonges in costs, foreign exchonge rotes ond interest roles. The Compony is exposed to fluctuolions in interest rotes os ils reguloted ROE is derived using o formuloic opprooch thot tokes into occount onticipoted inlerest roles, but is not currently exposed to moteriol commodity price risk or moteriol foreign exchonge risk.

The Compony periodicolly utilizes lnteresl role swop ogreemenls to mitigole elemenls o[ interest rote risk. Finonciol ossels creote o risk thot o counterporty will foil to dischorge on obligotion, cousing o finonciol loss. Derivotive finonciol instruments result in exposure to credit risk, since there is o risk o[ counterporty defoult. Hydro One monitors ond minimizes credil risk lhrough vorious techniques, including deoling with highly roted counterporlies, limiting totol exposure levels with individuol counterporties, entering into ogreements which enoble net settlement, ond by monitoring the finonciol condition of counterporties. The Compony does not trode in ony energy derivotives. The Compony is required to procure electricily on beholf of competitive retoilers ond certoin locol distribution componies for resole to their customers. The resulting concentrotions of credit risk ore mitigoted through the use of vorious security orrongements, including letters of credit, which ore incorporoted into the Compony's service ogreements with lhese retoilers in occordonce with the OEB's Retoil Settlement Code. The loilure to properly monoge these risks could hove o moteriol odverse effect on lhe Compony. Risks Reloting to Asset Condition ond Copitol Proiects The Compony continuolly incurs sustoinment ond development copitol expenditures ond monitors lhe conditlon of its tronsmission ossels to monoge the risk of equipmenl foilures ond to determine the need for ond timing of molor refurbishments ond replocements of its lronsmission ond diskibution infrostructure. However the lock of reol time monitoring of distribution ossets increoses the risk of distribution equipmenl foilure. The connection of lorge numbers of generotion focilities to the distribution net'work hos resulted in greoter thon expected usoge of some of the Compony's equipment. This lncreoses moinlenonce requirements ond moy occelerole the oging of the Compony's ossets. Execution of the Compony's copitol expendlture progroms, porticulorly for development copitol expenditures, is portiolly dependent on externol foctors, such os environmenlol opprovols municipol permits, equipment outoge schedules thot occommodote fie IESO, generolors ond lronsmission-connecled cuslomers, ond supply choin ovoilobility for equipment suppliers ond consulting services.

The expected rote ol return on pension plon ossels reflecls the Compony's long{erm expectotions. The Compony believes thot this ossumplion is reosonoble becouse, with the pension plon's bolonced investmenl opprooch, the higher volotility of equity investment relurns is intended to be offset by the greoter stobility ol fixed-income ond short-term investment returns.

The first step compores the foir volue of the opplicoble reporting unit to its corrying omount, including goodwill. lf the corrying omounl o[ the opplicoble reporting unit exceeds its foir volue, o second step is performed. The second slep requires on ollocotion of foir volue to the individuol ossets ond l;obilities using purchose price ollocotion in order lo determine the implied loir volue of goodwill. lf the implied foir volue of goodwill is less thon the corrying omounl, on impoirment loss is recorded os o reduction to goodwlll ond os o chorge to results o[ operotions.

Long-Lived Asset lmpoirment When circumstonces indicote the corrying volue of long-lived ossets moy not be recoveroble, the Compony evoluotes whether the corrying volue of such ossets, excluding goodwill, hos been impoired. For such longlived ossets, the Compony evoluotes whether impoirment moy exisl by estimoting future estimoted undiscounted cosh flows expected to result lrom the use ond eventuol disposition of the osset. When olternotive courses of oction to recover the corrying omounl of o long-lived osset ore under considerotion, o probobiliy weighted opprooch is used to develop estimoles o[ fulure undiscounted cosh flows. l[ the corrying volue of the long-lived osset is nol recoveroble bosed on the eslimoted fulure undiscounted cosh flows, on impoirment loss is recorded, meosured os the excess of the corrying volue of the osset over its foir volue. As o result, the ossel's corrying volue is odiusted lo its estimoted [oir volue.

As o result, such ossets ore only tested for impoirment in fie event thot the OEB disollows recovery, in whole or in port, or i{ such o disollowonce is iudged to be proboble. Hydro One regulorly monitors the ossets of its unreguloted Hydro One Telecom subsidiory for indicotions o[ impoirment.

AVU-E-17-_ and AVU-G-17-_ C.Lopez, Hydro One Schedule 3, Page I I I of 167 a a a a a a a a a a a 6 a ELECTRICITY INDUSTRY OVERVIEW General Overview The electricity industry is made up of businesses that generate, transmit, distribute and sell electricity. While traditionally a mature and stable industry, innovation and technological change are expected to have a significant impact on the industry in the foreseeable future. Hydro One's business is focused on the transmission and distribution of electricity. Transmission refers to the delivery of electricity over high voltage lines, typically over long distances, from generating stations to local areas and large industrial customers. Distribution refers to the delivery of electricity over low voltage power lines to end users such as homes, businesses and institutions. Overview of an Electricity System The basic configuration of a typical electricity system showing electricity generation, transmission and distribution is illustrated in the following diagram: a W8#*#*##-T;#g,*ffm, Generutor Transmission and distribution networks are sometimes referred to as the "electricity grid" or simply "the grid". For simpliciry, the diagram above does not show customers directly connected to the transmission system or distributed generation sources or other distributors that may be connected to the distribution system. THE ELECTRICITY INDUSTRY IN ONTARIO Regulation of Transmission and Distribution General The Electricity Act and the Ontario Energy Board Act establish the general legislative framework for Ontario's electricity market. The activities of transmitters and distributors in Ontario are overseen by three main regulatory authorities: (i) the OEB, (ii) the IESO, and (iii) the National Energy Board. Ontario Energt Board The OEB is an independent and impartial public regulatory agency. The Ontario Energy Board Act provides the OEB with the authority to regulate Ontario's electricity market, including the activities of transmitters and distributors. The OEB has the following objectives in relation to the electricity industry: to protect the interests of consumers with respect to prices and the adequacy, reliability and quality of electricity service, Exhibit No. 47 Case Nos. AVU-E-17-- and AVU-G-I7-- C.Lopez, Hydro One Schedule 3, Page 112 of 167 TronJonner (lncrcor.d b Highce \ehogc) Ironrmisrim Syrkm Tmnsformer lDxreo*d to lo*cr Volhgcl Dirtribution 5y:hm Ironslsrmor (DG<r.olGd ta to.rer \&ltogcl a a to promote economic efficiency and cost effectiveness in the generation, transmission, distribution, sale and demand management of electricity and to facilitate the maintenance of a fi nancially viable electricity industry, to promote electricity conservation and demand management in a manner consistent with the policies of the Province, including having regard to the consumer's economic circumstances, a to facilitate the implementation of a smart grid in Ontario, and to promote the use and generation of electricity from renewable energy sources in a manner consistent with the policies of the Province, including the timely expansion or reinforcement of transmission systems and distribution systems to accommodate the connection of renewable energy generation facilities. The OEB is responsible for, among other things, approving transmission and distribution rates in Ontario. It also approves the construction, expansion, or reinforcement of transmission lines greater than two kilometres in length, as well as mergers, acquisitions, amalgamations and divestitures involving distributors, transmitters and other entities which it licenses. The activities of transmitters and distributors are subject to the conditions of their licenses and a number of industry codes issued by the OEB. These codes and other requirements prescribe minimum standards of conduct and service for licensed parlicipants in the electricity market. IESO The IESO manages the operation and reliability of Ontario's bulk power system and administers the wholesale electricity market. It is governed by a board whose chair and directors are appointed by the Province. The IESO also coordinates province-wide conservation efforts. Transmitters and other wholesale market participants must comply with the Market Rules issued by the IESO. The Market Rules require transmitters to comply with mandatory North American reliability standards for transmission issued by the North American Electric Reliability Corporation ('NERC") and the Northeast Power Coordinating Council, Inc. ("NPCC"). The IESO enforces these reliability standards and coordinates with system operators and reliability agencies in other jurisdictions to ensure energy adequacy and security across the interconnected bulk electricity system in North America. National Energt Board The National Energy Board is an independent federal regulatory agency, governed by the National Energ,, Board Act (Canada) and has jurisdiction over the construction and operation of intemational power lines, as well as interprovincial lines that are designated as being under federal jurisdiction (of which there are currently none). As Hydro One owns and operates I I active international power lines connecting Ontario's transmission system with transmission systems in Michigan, Minnesota and New York, Hydro One is required to hold several certificates and permits issued by the National Energy Board and is subject to its mandatory electricity reliability standards and reporting requirements. Transmission Transmission companies own and operate transmission systems that deliver electricity over high voltage lines. Hydro One's transmission system accounts for approximately 98o/o of Ontario's electricity transmission capacity based on the revenues approved by the OEB. The Company's transmission system is interconnected to systems in Manitoba, Michigan, Minnesota, New York and Quebec and is part of the North American electricity grid's Eastern Interconnection. The Eastern Interconnection is a contiguous electricity transmission system that extends from Manitoba to Florida and from east of the Rocky Mountains to the North American east coast. Being part of the Eastern Interconnection provides benefits Exhibit No. 48 Case Nos. AVU-E-I7-- and AVU-G-I7-- C.Lopez, Hydro One Schedule 3, Page I l3 of 167 a o to Ontario, such as greater security and stability for Ontario's transmission system, emergency support when there are generation constraints or shoftages in Ontario, and the ability to exchange electricity with other jurisdictions. Distribution Distributors own and operate distribution systems that deliver electricity over power lines at voltages of 50kV or less to end users. In Ontario, as at December 31, 2015,71local distribution companies provided electricity to approximately five million customers. During 2016, Hydro One completed integration of two local distribution companies. The distribution industry in Ontario is fragmented, with the l5 largest local distribution companies accounting for approximately 78%o of the province's customers. Through its wholly-owned subsidiary Hydro One Inc., Hydro One owns the largest local distribution company in Ontario, which serves over 1.3 million, predominantly rural customers, or approximately 260/o of the total number of customers in Ontario. A local distribution company is responsible for distributing electricity to customers in its OEB-licensed service territory, and in some cases to other distributors. A service territory may cover large portions or all of a particular municipality, or an otherwise-defined geographic area. Distribution customers include homes, commercial and industrial businesses and institutions such as governments, schools and hospitals. Legislative Provisions Specific to Hydro One In addition to legislation in Ontario that impacts all transmitters and distributors, there is legislation that is specific to Hydro One. Specifically, the Electricity Act requires Hydro One's head office and principal grid control centre to be maintained in Ontario, restricts the disposition of substantially all of its OEB- regulated transmission or distribution business, prohibits any change to its jurisdiction of incorporation, requires the Company to have an ombudsman, contains a l0o/o ownership restriction with respect to Voting Securities and restricts the Province from selling Voting Securities if it would own less than40oh of the Voting Securities of any class or series as a result of the sale. Ombudsman The Electricity Act requires the Company to have an ombudsman to act as a liaison with customers and to establish procedures for the ombudsman to inquire into and report to the Board on matters raised with the ombudsman by or on behalf of customers. See "General Development of the Business - Customer Focus - Ombudsman" for more information. 1 0% Ownership Restriction The Electricity Act imposes share ownership restrictions on the Voting Securities. These restrictions provide that no person or company (or combination of persons or companies acting jointly or in concert) may beneficially own or exercise control or direction over more than 10%o of any class or series of Voting Securities, including common shares of the Company (the "Share Ownership Restrictions"). The Share Ownership Restrictions do not apply to Voting Securities held by the Province, nor to an underwriter who holds Voting Securities solely for the purpose of distributing those securities to purchasers who comply with the Share Ownership Restrictions. The articles of Hydro One Limited provide for comprehensive enforcement mechanisms that are applicable in the event of a contravention of the Share Ownership Restrictions. Exhibit No. 4 Case Nos. AVU-E-17-_ and AVU-G-17-_ C.Lopez, Hydro One Schedule 3, Page ll4 of 167 9 Maintenance of 40% Ownership As of December 31,2016, the Province owned approximately 70.1% of Hydro One Limited's common shares. The Province has indicated that it intends to sell further common shares over time, until it holds approximately 40% of Hydro One Limited. See the Annual MD&A under the heading "Risk Management and Risk Factors" for more information. The Electricity Act restricts the Province from selling Voting Securities (including common shares of Hydro One Limited) if it would own less than 40o/o of the outstanding number of Voting Securities of that class or series after the sale. If as a result of the issuance of additional Voting Securities by Hydro One Limited, the Province owns less than40o/o of the outstanding number of Voting Securities of any class or series, the Province must, subject to the approval ofthe Lieutenant Governor in Council and the necessary appropriations from the Legislature, take steps to acquire as many Voting Securities of that class or series as are necessary to increase the Province's ownership to not less than 40o/o of the outstanding number of Voting Securities of that class or series. The manner in which, and the time by which, the Province must acquire these additional Voting Securities will be determined by the Lieutenant Governor in Council. The Province has been granted pre-emptive rights by Hydro One Limited to assist it in meeting its ownership requirements under the Electricity Act as described under "Agreements with Principal Shareholder - Governance Agreement - Other Matters - Pre-emptive Rights". Elimination of Certain Legislation With Respect to Hydro One Ln2015, priorto completion of the initial public offering of Hydro One Limited, Hydro One Inc. and its subsidiaries ceased to be subject to a number of Ontario statutes that apply to entities owned by the Province. Hydro One Limited is similarly not subject to those statutes. In making the transition, the Auditor General of Ontario, the Financial Accountability Officer, the Information and Privacy Commissioner and the Provincial Ombudsman continued to exercise certain of their powers with respect to the Company in ceftain limited circumstances until December 4,2015. The Information and Privacy Commissioner could also continue to issue certain orders with respect to the Company until lune 4,2016. The Company is required under the Financial Administration Act (Ontario) and the Auditor General Act (Ontario) to provide financial information to the Province for the Province's public reporting purposes. Recent Legislative Amendments Affecting the Electricity Industry Generally Tax Incentives Tax incentives were included in the 2015 Ontario Budget to promote consolidation in the electricify distribution sector. The 2015 Ontario Budget announced a reduction in the tax rate for transfers of electricity assets from 33%o to 22%o and to NIL for distributors with fewer than 30,000 customers. In addition, the budget also introduced a capital gains exemption where capital gains arise as a result from exiting the payments in lieu of corporate taxes regime. These changes apply for the period beginning January 1,2016, and ending December 31,2018. Ontario Rebate for Electricity Consumers Act, 201 6 The Ontario Rebate for Electricity Consumers program commenced on January 1, 2017 . This program provides financial assistance to residential, farm, small business and other eligible consumers in respect of electricity costs equalto a rebate of eight percent (8%) of the base invoice amount for each billing period. This rebate appears as a line item on eligible consumers' electricity bills. Exhibit No. 4 Case Nos. AVU-E-17-_ and AVU-G-17-_ C.Lopez, Hydro One Schedule 3, Page I 15 of 167 t0 Energt Statute Law Amendment Act, 2016 The Energt Statute Law Amendment AcL20l6 came into force on January 1,2017. This Act affects the transmission and distribution sector of the electricity industry in Ontario, amending various sections of the Ontario Energy Board Act, the Electricity Act and the Green Energy Act, 2009 (Ontario). The Energt Statute Law Amendment Act, 2016 amended the Electricity Act to require the Minister of Energy to produce long-term energy plans that may require the OEB and the IESO to issue implementation plans to achieve the objectives of those plans and the OEB would be guided by such plans' objectives in exercising its powers and performing its duties. The plans may require the IESO to enter into contracts to procure or develop, among other things, transmission systems or any part of such systems. Once the IESO has commenced the procurement process, the OEB is prohibited from granting leave to construct except where the applicant is the parly with whom the IESO has entered into a contract for the development or construction of the transmission project. The Energy Statute Low Amendment Act,20l6 also prohibits new feed-in tariffprograms, but grandfathers existing ones. Climate Change Mitigation ond Low-carbon Economy Act,2016 Pursuant to the Climate Change Mitigation and Low-carbon Economy Act, 2016, the Province introduced a cap and trade program in Ontario beginning January l, 2017. The program caps the amount of greenhouse gas emissions that Ontario homes and businesses are allowed to emit, and lowers that limit over time. Hydro One Networks Inc., an indirect wholly-owned subsidiary of Hydro One Limited, is deemed a mandatory participant in the cap and trade program based on its annual carbon dioxide equivalent emissions. As required, Hydro One Networks Inc. registered under the program in November 2016, and will comply with its requirements. Bill 27 - Burden Reduction Act, 2016 Bill 27 was introduced into the Legislative Assembly of Ontario in September 2016 and received Royal Assent on March 22,2017. This is an omnibus bill amending various statutes, including the Ontario Energy Board Act and the Electricity Act. Bill 27, among other things, amends the Ontario Energy Board Act in a number of ways related to deferral and variance account review and oversight and review of transactions between transmitters and distributors and electricity generators. Bill 95 - An Act to amend the Ontario Energt Board Act, 1998 Bill 95 was introduced into the Legislative Assembly of Ontario and received Royal Assent on February 22, 2017. Bill 95 impacts a distributor's ability to disconnect customers by broadening the power of the OEB to prescribe, as a condition of a distributor's licence, periods during which disconnections of low- volume consumers may not take place. At the end of February 2017, the OEB issued a decision and order amending the licenses of all Ontario electricity distributors prohibiting the disconnection of residential customers by reason of non-payment for the balance of the 2017 winter period. See "General Development of the Business - Customer Focus - Winter Moratorium and Winter Relief Program" for more information. Exhibit No. 4 Case Nos. AVU-E-l 7-_ and AVU-G-17-_ C. Lopez, Hydro One Schedule 3, Page 116 of 167 ll RATE-REG ULATED UTILITIES Rate Applications in Ontario Framework The term "rate-regulated" is used to refer to an electricity business whose rates for transmission, distribution or other services are subject to approval by a regulator. The rate base of a rate-regulated utility refers to the net book value of the utility's assets for regulatory purposes. Rate base differs from a utility's total assets for accounting purposes, primarily because it includes the regulated assets of a utility. The OEB is the regulator that approves electricity transmission and distribution rates in Ontario. Transmission rates have historically been determined based on a cost-of-service model, while distribution rates are generally determined using a performance-based model. These models are reviewed and modified by the OEB from time to time. In February 2016, the OEB updated the filing requirements for electricity transmission applications and introduced new revenue requirement setting options. The requirements changed the framework for setting a transmitter's revenue requirement from a cost-of-service approach to a performance-based approach similar to that outlined in the RRF for electricity distributors. To facilitate the transition to the new framework, existing transmitters may still apply for revenue requirement approval based on a one or two year cost-of-service application for their first application following the issuance of the new filing requirements. In a cost-of-service model, a utility charges rates for its services that allow it to recover the costs of providing its services and earn an allowed return on equity. A utility's return on equity or "ROE" is the rate of return that a regulator allows the utility to earn on the equity portion of the utility's rate base. The costs of providing its services must be prudently incurred. Cost savings are typically passed on to customers in the form of lower rates reflected in future rate decisions. In a cost-of-seruice model, the utility has the potential to retain cost savings that are achieved in the intervening years between rate decisions. Cost of Service ($) + Return on Equity (S)Revenue Requirement ($) In a performance-based model, a utility also charges rates for its services that allow it to recover the costs of providing its services and earn an allowed return on equity. However, the rates charged by the utility in a performance-based model assume that the utility becomes increasingly efficient over time, resulting in lower costs to provide the same service. If a utility achieves cost savings in excess of those established by the regulator, the utility may retain some or all of the benefits of those cost savings, which may permit the utility to earn more than its allowed return on equity.

GENERAL DEVELOPMENT OF THE BUSINESS The following key events occurred in 20 I 5, 2016 and early 2017 in respect of Hydro One. Incorporation and Initial Public Offering On August 31,2015, Hydro One Limited was incorporated by the Province as its sole shareholder On November 5,2015, Hydro One Limited completed its initial public offering on the TSX by way of a secondary offering of 81,100,000 common shares by the Province at a price of $20.50 per share for aggregate gross proceeds to the Province of $1,662,550,000. On November 12,2015, the underwriters in the initial public offering exercised their option to purchase an additional 8,150,000 common shares from the Province at a price of $20.50 per share for additional aggregate gross proceeds to the Province of $167,075,000. Hydro One Limited did not receive any proceeds from the initialpublic offering. Acquisition of Hydro One Inc. Prior to the closing of the initial public offering, all of the issued and outstanding common shares of Hydro One Inc. were acquired by Hydro One Limited. Under applicable Canadian securities laws, the acquisition of all of the issued and outstanding shares of Hydro One Inc. was considered a "significant acquisition". Hydro One Limited filed a business acquisition report in respect of the acquisition on January 14,2016. See "Business of Hydro One - Reorganizations" for more information. Hydro One Brampton Networks Inc. On August 31 , 2015, all of the issued and outstanding shares of Hydro One Brampton Networks Inc. were transferred to the Province. Hydro One was not a participant in nor did it receive any proceeds from the transfer of Hydro One Brampton Networks Inc. to the Province. Following the transfer to the Province, Hydro One provided certain management, administrative and smart meter network services to Hydro One Brampton Networks Inc. pursuant to service level agreements. These agreements terminated as of Febrtary 28,2017. Secondary Common Share Offering On April 14,2016, the Province completed a secondary offering of 72,434,800 common shares of Hydro One Limited at a price of $23.65 per share for aggregate gross proceeds to the Province of $1,713,083,020. On April29,2016,the underwriters in the secondary offering exercised their option to purchase an additional 10,865,200 common shares from the Province at a price of $23.65 per share for additional aggregate gross proceeds to the Province of $256,961,980. Following the completion of the transaction, the Province held approximately 70.1% of total issued and outstanding common shares. Hydro One Limited did not receive any proceeds from the sale of the common shares by the Province. Exhibit No. 4 Case Nos. AVU-E-17-_ and AVU-G-17-_ C.Lopez, Hydro One Schedule 3, Page 119 of 167 a a 14 Hydro One Remote Communities Inc. - generates and supplies electricify to remote communities in northern Ontario. First Nations and Hydro One Limited Shares In July 2016, the Province and First Nations in Ontario, as represented by the Chiefs-in-Assembly, announced an agreement-in-principle for the Province to sell to First Nations up to approximately l5 million shares of Hydro One Limited, depending on the level of First Nation participation. All First Nations have been invited to participate. A minimum threshold of 80% First Nation participation by the end of 201 7 is required for this transaction to close. Hydro One Limited is not a parfy to this transaction. Agreement to Acquire Orillia Power In August 2016,the Company reached an agreement to acquire Orillia Power, an electricity distribution company located in Simcoe County, Ontario, for approximately $41 million, including the assumption of approximately $ I 5 million in outstanding indebtedness and regulatory liabilities, subject to closing adjustments. The acquisition is subject to regulatory approval by the OEB. Acquisition of Great Lakes Power On October 31,2016, following receipt of regulatory approvalof the transaction by the OEB, Hydro One completed the acquisition of Great Lakes Power, an Ontario regulated electricity transmission business operating along the eastern shore of Lake Superior, north and east of Sault Ste. Marie, Ontario. The total purchase price for Great Lakes Power was approximately $376 million, including the assumption of approximately $150 million in outstanding indebtedness. On January 16,2017,Great Lakes Power's name was changed to Hydro One Sault Ste. Marie LP. Integration of Haldimand Hydro and Woodstock Hydro In 2015, the Company acquired Haldimand Hydro and Woodstock Hydro, two Ontario-based local distribution companies. In September 2016, the Company successfully completed the integration of both entities, including the integration of employees, customer and billing information, business processes, and operations. Acquisitions Generally The Company intends to continue to evaluate local distribution company consolidation opportunities in Ontario and intends to pursue those acquisitions which deliver value to the Company and its shareholders. Over time, the Company may also consider larger-scale acquisition opportunities or other strategic initiatives outside of Ontario to diversiff its asset base and leverage its strong operational expertise. These acquisition opportunities may include other providers of electrical transmission, distribution and other similar services in Canada and in the United States. Customer Focus Hydro One is transitioning into a corporation which is more commercially oriented; that is, one that has a greater focus on customers, greater corporate accountability for performance outcomes, and company- wide increase in productivity and efficiency. Customer Service Hydro One is committed to delivering significant value to customers by becoming easier to do business with, being available when customers need assistance, and always staying connected. This includes specific, measurable commitments to customers that encompass all areas of service. Hydro One's billing system is stable and outperforming its previous system in terms of timeliness, accuracy and reliability. In 2017, the Company intends to launch a new corporate website, improve its self-service portal, and introduce a newly designed customer bill. Additionally, the Company is committed to increasing the Exhibit No.4l5 CaseNos. AVU-E-I7--and AVU-G-I7-- C. Lopez, Hydro One Schedule 3, Page 'i,20 of 167 availability of customer service at the local level, and increasing face to face customer engagement. Review of Operations Hydro One has been focused on the identification of opportunities for improved corporate performance and the development of strategies to drive more efficient, cost-effective operations. Hydro One conducts regular reviews of key corporate activities and programs, covering areas such as construction services and project management practices, asset deployment and controls, information technology and cybersecurity, vegetation management practices, fleet services and utilization, supply chain management and business continuity planning. Operational improvements in capital planning and execution have already been observed, and improvements have been made to work execution process. The OEB's rate decisions also contain directions to Hydro One to become more cost efficient and improve value to customers. l{inter Moratorium und Winter Relief Program Hydro One has an existing policy (the winter disconnection moratorium) that from December I to March 3l it will not disconnect residential customers whose accounts are in arrears. In 2016, Hydro One instituted its winter disconnection moratorium as of November 25. Hydro One announced its new Winter Relief Program in December 2016, as an extension of its existing winter disconnection moratorium. This new initiative is intended to help residential customers facing extreme hardship and who have had their electricity service disconnected by reaching out to these customers directly to help re-connect their electricity service for the remainder of the winter. As part of the program, Hydro One will waive reconnection fees and also work with customers to determine payment options to bring their accounts up-to-date and to evaluate various support programs in which certain customers may be eligible to participate. Ontario Re bate for E lectricity Consu mers Program See "The Electricity Industry in Ontario - Recent Legislative Amendments Affecting the Electricity Industry Generally - Ontario Rebate for Electricity Consumers Act, 2016" for information on the Ontario Rebate for Electricity Consumers program. Ombudsman The Electricity Act requires that the Company have an ombudsman to act as a liaison with customers and to establish procedures for the ombudsman to inquire into and repoft to the Board on matters raised with the ombudsman by or on behalf of customers. These procedures are set out in a written mandate and terms of reference. The role of the ombudsman is to facilitate resolution of complaints by customers of the Company that remain unresolved after having been processed through the Company's complaints handling process. The ombudsman is an impartial and independent investigator, who makes recommendations to facilitate the resolution of both individual and systemic issues with a view to achieving a resolution that is fair to both the customer and the Company. The main purposes of the ombudsman are to address procedural and substantive unfairness, handle unresolved complaints, conduct systemic reviews that will lead to improvements in programs and systems, suppoft the Company in holding its employees accountable for carrying out the Company's directives and their responsibilities, and support the Board in its mandate to govern in a just, fair, and equitable manner. The ombudsman also works with the OEB to maintain integrated procedures for liaising with the Company and inquiring into matters raised by customers with the ombudsman. The ombudsman is an office of last resort within the Company. Exhibit No. 4 Case Nos. AVU-E-t 7-_ and AVU-G-17-_ C. Lopez, Hydro One Schedule 3, Page 121 of 167 16 BUSINESS OF HYDRO ONE Business Segments Through its wholly-owned subsidiary Hydro One Inc., Hydro One is Ontario's largest electricity transmission and distribution utility with approximately $25.3 billion in assets and2016 revenues of over $6.5 billion. Hydro One owns and operates substantially all of Ontario's electricity transmission network and is the largest electricity distributor in Ontario by number of customers. The Company's regulated transmission and distribution operations are owned by Hydro One Inc., a wholly-owned subsidiary of Hydro One Limited. Hydro One delivers electricity safely and reliably to over 1.3 million customers across the province of Ontario, and to large industrial customers and municipal utilities. Hydro One Inc. owns and operates over 30,000 circuit kilometres of high-voltage transmission lines and approximately 123,000 circuit kilometres of primary low-voltage distribution lines. Hydro One has three business segments: (i) transmission; (ii) distribution; and (iii) other business. Each of the three segments is described below. Hydro One's transmission and distribution businesses are both operated primarily through Hydro One Networks Inc. This allows both businesses to utilize common operating platforms, technology, work processes, equipment and field staff and thereby take advantage of operating efficiencies and synergies. For regulatory purposes, Hydro One Networks Inc. files separate rate applications with the OEB for each of its licensed transmission and distribution businesses. Transmission Business Overview Hydro One's transmission business consists of owning, operating and maintaining Hydro One's transmission system, which accounts for approximately 98% of Ontario's transmission capacity based on revenue approved by the OEB. All of the Company's transmission business is carried out by its wholly- owned subsidiary Hydro One Inc., through its wholly-owned subsidiary Hydro One Networks Inc. and through other wholly-owned subsidiaries of Hydro One Inc. that own and control Great Lakes Power (now Hydro One Sault Ste. Marie LP), as well as through the Company's 66o/o interest in B2M Limited Partnership. B2M Limited Partnership is a limited partnership between Hydro One and the Saugeen Ojibway Nation, which owns the transmission line assets relating to two circuits between Bruce TS and Milton TS. Hydro One's transmission business represented approximately 51%, of its total assets as at December 31,2016, and accounted for approximately 5l% of its total revenue in 2016, net of purchased power and 50%o of its total revenue in 201 5, net of purchased power. The Company's transmission business is one of the largest in North America and is a rate-regulated business that earns revenues mainly from charging transmission rates that are subject to approval by the OEB. In February 2016,the OEB updated the filing requirements for electricity transmission applications and introduced new revenue requirement setting options. During the transition period from the cost-of- service model to the performance-based model, the Company's transmission rates are determined based on a cost-of-service model. Transmission rates are collected by the IESO and are remitted by the IESO to Hydro One on a monthly basis, which means that Hydro One's transmission business has no direct exposure to end-customer counterparty risk. Transmission rates are based on monthly peak electricity demand across Hydro One's transmission network. This gives rise to seasonal variations in Hydro One's transmission revenues, which are generally higher in the summer and winter due to increased demand, and lower during other periods of reduced demand. Hydro One's transmission revenues also include revenues associated with exporting energy to markets outside of Ontario. Ancillary revenue includes revenues from providing maintenance services to generators and from third parfy land use. Exhibit No. 4 Case Nos. AVU-E-17-_ and AVU-G-l 7-_ C.Lopez, Hydro One Schedule 3, Page 122 of 167 17 Business The Company's transmission system seryes substantially all of Ontario, with the exception of the James Bay and Fort Erie areas, and transported approximately 137 TWh of energy throughout the province in 20 16. Hydro One's transmission customers consist of 44 local distribution companies (including Hydro One's own distribution business) and 87 large industrial customers connected directly to the transmission network, including automotive, manufacturing, chemical and natural resources businesses. Electricity delivered over the Company's transmission network is supplied by 126 generators in Ontario and electricity imported into the province through interties. Interties are transmission interconnections between neighbouring electric systems that allow power to be imported and exported. The high voltage power lines in Hydro One's transmission network are categorized as either lines which form part of the "bulk electricity system" or "area supply lines". Power lines which form part of the bulk electricity system typically connect major generation facilities with transmission stations and often cover long distances, while area supply lines serve a local region. Ontario's transmission system is connected to the transmission systems of Manitoba, Michigan, Minnesota, New York and Quebec through the use of interties, allowing for the import and export of electricity to and from Ontario. Hydro One's transmission assets were approximately Sl3 billion as at December 31,2016 and include transmission stations, transmission lines, a control centre and telecommunications facilities. Hydro One has approximately 306 in-service transmission stations and over 30,000 circuit kilometres of high voltage lines whose major components include cables, conductors and wood or steel suppoft structures. All of these lines are overhead power lines except for approximately 277 circuit kilometres of underground cables located in certain urban areas. B2M Limited Partnership is Hydro One's partnership with the Saugeen Ojibway Nation with respect to the Bruce-to-Milton transmission line. B2M Limited Partnership owns the transmission line assets relating to two circuits between Bruce TS and Milton TS, while Hydro One owns the transmission stations where the lines terminate. Hydro One maintains and operates the Bruce-to-Milton line. Hydro One has a 66%o economic interest in the partnership. Hydro One's transmission network is managed from a central location. This centre monitors and controls the Company's entire transmission network, and has the capability to remotely monitor and operate transmission equipment, respond to alarms and contingencies and restore and reroute interrupted power. There is also a backup facility which would be staffed in the event of an evacuation of the centre. Hydro One uses telecommunications systems for the protection and operation of its transmission and distribution networks. These systems are subject to very stringent reliability and security requirements, which help the Company meet its reliability obligations and facilitate the restoration of power following service interruptions. On October 31,2016, following receipt of regulatory approval of the transaction by the OEB, Hydro One completed the acquisition of Great Lakes Power, an Ontario regulated electricity transmission business operating along the eastem shore of Lake Superior, north and east of Sault Ste. Marie, Ontario. The total purchase price for Great Lakes Power was approximately 5376 million, including the assumption of approximately $150 million in outstanding indebtedness. On January 16,2017, Great Lakes Power's name was changed to Hydro One Sault Ste. Marie LP. See "General Development of the Business - Acquisitions Generally" for more information. Exhibit No. 4 Case Nos. AVU-E-17-_ and AVU-G-17-_ C. Lopez, Hydro One Schedule 3, Page 123 of 167 l8 Regulation Transmission Rate Setting As discussed under "Rate-Regulated Utilities", transmission rate setting in Ontario has changed. The OEB has created two new revenue plan options: the Custom Incentive Rate Setting Plan (the "Custom IR Method") and the Incentive Index Rate Setting Plan (the "Revenue Cap Index"). Transmitters may still apply for revenue requirement approval based on a one or two year cost-of-service application for their first application following the issuance of the filing requirements, as the OEB has recognized that a transition period may be needed. Under the Custom IR Method, the revenue requirement is adjusted though the rate term to reflect forecasts, the OEB's inflation analysis, and intemal and extemal benchmarking evidence. Under the Revenue Cap Index the first year's revenue requirement reflects the transmitter's cost of service, and annually thereafter, this amount is subject to a formulaic increase reflecting productivity and stretch commitments proposed by the transmitter. Revenue Cap Index applicants can request incremental capital funding. The OEB sets transmission rates based on a two-step process. First, all transmitters apply to the OEB for the approval of their revenue requirements. Second, the OEB aggregates the total revenue requirements of all transmitters in Ontario and applies a formula to arrive at a single set of rates that are charged to ratepayers for the three types of transmission services applicable in Ontario, namely: network services, line connection services and transformation connection services. The three separate rates charged for these services are the same for all transmitters and are referred to as "uniform transmission rates". Uniform transmission rates for all transmitters are set by the OEB on an annual basis, using the revenue requirements set out in the most recent rate decision issued for each transmitter. The updated filing requirements for transmitters mandate that steps be made towards the integration of core RRF concepts into revenue requirement applications. Transmitters applying for revenue requirements under the Custom IR Method or Revenue Cap Index must include (i) evidence of the continuous improvement and efficiency gains anticipated to be achieved over the rate term; (ii) a mechanism to protect ratepayers in the event of eamings significantly in excess of the regulatory net income supported by the return on equity established in the approved revenue requirement; and (iii) proposed performance metrics applicable to their individual circumstances. A key component of rate- setting under the RRF is benchmarking evidence to support cost forecasts and system planning proposals. A transmitter must apply for the approval of its revenue requirement for an initial base year covered by the rate decision. The revenue requirement for subsequent years is determined based on a formula that accounts for inflation and certain productivity factors set by the regulator. The revenue requirement in these subsequent years is set on the assumption that the transmitter is lowering its cost of service over the period covered by the rate decision due to efficiency or productivity improvements. A transmitter is permitted to retain all or a portion of the cost savings achieved in excess of the estimate established by the regulator during the period covered by the rate decision. Recent Transmission Rate Applications Hydro One Networks Inc., B2M Limited Partnership and Great Lakes Power (now Hydro One Sault Ste. Marie LP) file separate applications for the approval of their revenue requirements for transmission services. In January2015, the OEB approved Hydro One Networks Inc.'s 2015 transmission rate order for transmission services, which provided for a revenue requirement of 51 ,477 million for 2015 and Sl,5l6million for 2016 (excluding B2M Limited Partnership). These revenue requirements reflect an Exhibit No. 4l9 Case Nos. AVU-E-I7-- and AVU-G-I7-- C. Lopez, Hydro One Schedule 3, Page 'I24 of 167 approved rate base of $9,65 I million, retum on equity of 9.30Yo and deemed capital structure of 60%o debt and 40%o equity. In January 2016, the OEB issued its decision and order on 2016 transmission revenue requirement for Hydro One Networks Inc. approving a revenue requirement of approximately $1,480 million based on an approved rate base of $10,040 million and a return on equity of 9.19Y". InMay 2016, Hydro OneNetworks Inc. filed a transmission rate application with the OEB for its 2017- 2018 revenue requirements on a cost of service basis, electing to take advantage of the transition period available to transmitters before the OEB requires transmitters to choose between the two incentive-based revenue plan options. In its application, Hydro One Networks Inc. requested the OEB's approval of rates revenue requirements of $1,505 million for 2017 and S1,586 million for 2018. These rates revenue requirements reflect the requested rate base of S10,554 million for 2017 and $11,226 million for 2018, and reflect an allowed ROE of 9.19%o for eachyear. In December 2016, pursuant to the OEB's publication of its cost of capital parameters for 2017 rate year, Hydro One Networks Inc. updated its transmission rate application to reflect the change. The revised rates revenue requirement for 2017 is $1,487 million and $1,558 million for 2018. Furthermore, the cost of capital update reflects ROE, short-term and long-term debt cost updates. As a result, the ROE in the application has been updated to 8.'18%o for 2017 and the same rate is being a placeholder for 201 8. In preparing its application, Hydro One Networks Inc. carried out customer engagement and incorporated the feedback into its application. As part of the transmission rate application, Hydro One Networks Inc. also filed its proposed five-year transmission system capital plan. In March 2015,B2M Limited Partnership filed an application for revenue requirements covering the 2015 to 2019 period. B2M Limited Partnership requested revenue requirements of $39 million for 2015, 536 million for 2016, $37 million for 2017, 538 million for 2018 and $37 million for 2019.ln January 2016, the B2M Limited Partnership revenue requirement was approved. In December 2016, B2M Limited Partnership filed a draft rate order with a revised 2017 revenue requirement of $34 million. See also the Annual MD&A under the subheading "Regulation - B2M LP". In December 2016, Great Lakes Power filed an application with the OEB for 2017 rates, requesting an increase to the approved 2016 revenue requirement of l.9o/o, resulting in an updated revenue requirement of$41 million. Rel iabi I itv Standards for Transmission The Company's transmission business is required to comply with various rules and standards for transmission reliability, including mandatory standards established by the NERC and the NPCC, both of which are industry organizations involved in promoting and improving the reliability of transmission networks in North America. These reliability standards are enforced by both the IESO and the National Energy Board. Among its standards, the NERC has also established and continues to issue revised requirements to ensure that utilities and other users, owners and operators of the bulk electricity system in North America have appropriate procedures in place to protect critical infrastructure from cyber-attacks. Hydro One's physical, electronic and information security processes have been and are being upgraded to meet these revised requirements. Hydro One expects to continue to perform additional work and incur further costs to comply with the NERC's updated and revised standards. Hydro One anticipates that these costs will be incurred annually over a number of years and will be recovered in rates. See the Annual MD&A under the subheadings "Risk Management and Risk Factors - Compliance with Laws and Regulations; - Risk Associated with Information Technology Infrastructure and Data Security; - Risks Relating to Asset Condition and Capital Projects" for more information. Exhibit No. 4 Case Nos. AVU-E-I7- and AVU-G-I7- i.Lop".,Hydro one 20 Schedule 3, Page 125 of 167 Regional Planning The OEB oversees regional planning processes to ensure that transmission and distribution investments are coordinated at a regional level. The OEB has indicated it will rely on regional planning studies and reports to support rate applications submitted by transmitters and distributors and "leave to construct" applications submitted by transmitters. In Ontario, the regional planning process is led by the transmitter responsible for a particular geographic region. For this purpose, the province is divided into 2l regions. As the largest transmitter in Ontario, Hydro One plays a key role in the regional planning process and is responsible for leading the regional planning process in 20 ofthe 2l designated regions. The first cycle of the regional planning process for all of the 2l regions is expected to be completed in 201'7. Once a transmission and distribution infrastructure plan is finalized, the transmitter responsible for each region will take steps to implement the recommended transmission investments and distributors in the region will implement the recommended distribution investments in their respective service territories. In conducting regional planning, Hydro One works closely with the IESO and all distributors in the region to jointly identif needs and develop transmission and distribution investment options. Hydro One also coordinates with the IESO on its Integrated Regional Resource Planning process. The Company incurs both sustaining capital expenditures and development capital expenditures. Sustaining capital expenditures are those investments required to replace or refurbish lines or station components to ensure that transmission assets continue to function as originally designed. Hydro One's plans to maintain, refurbish or replace existing assets are based upon risk assessments, asset condition assessments and end-of-service life criteria specific to each type of asset. Priorities are assigned to each type of investment based upon the extent of the risks that it mitigates. Investments to sustain Hydro One's transmission assets are critical to maintain the safety, reliability and integrity of its existing transmission network. Hydro One's sustainment capital plan is designed to maintain Hydro One's transmission reliability performance, as determined by measures such as the average length (in minutes) of unplanned interuptions per delivery point. The Company expects that significant investments will be required in its existing infrastructure over the long term. The Company's development capital expenditure plan is designed to address Ontario's changing generation profile, accommodate load growth in areas throughout Ontario and support the expected change in generation mix. Development capital expenditures include those investments required to develop and build new large-scale projects such as new transmission lines and stations and smaller projects such as transmission line or station reinforcements, extensions or additions. The Company engages with various stakeholders, including its customers, as it develops its capital plans. It also engages affected communities and parties who may be impacted by individual projects. The Company also consults with First Nations and Mdtis communities whose rights may be affected by its projects. Exhibit No. 4 Case Nos. AVU-E-17-_ and AVU-G-17-_ C. Lopez, Hydro One Schedule 3, Page 126 of 167 2t Capital Expenditures The Company anticipates that it will spend approximately S I ,086 million to $ 1,486 million per year, over the next five years, on capital expenditures relating to its transmission business. The Company's capital expenditure plans are included in Hydro One's applications to the OEB for transmission rates. See "Capital Investments - Future Capital Investments" in the Annual MD&A for more information on future capital expenditures. Competitive Co nditions The Company's operations are currently limited to Ontario, where the Company operates and maintains substantially all of Ontario's transmission system. Competition for transmission services in Ontario is currently limited. The adoption by the OEB of uniform transmission rates that apply to all transmitters also reduces the financial incentive for customers to seek alternative transmission providers, since each transmitter in Ontario charges the same uniform rate for transmission services. Hydro One competes with other transmitters for the opportunity to build new large-scale transmission facilities in Ontario. Management believes that Hydro One is well-positioned to pursue the development of such facilities. However, the competitive process was amended by the proclamation of the Energt Statute Law Amendment Act, 2016 to allow for the selection of a transmitter outside the existing competitive process. See "The Electricity Industry in Ontario - Recent Legislative Amendments Affecting the Electricity Industry Generally- Energt Statute Low Amendment Act, 2016" for more information. Hydro One does not compete with other transmitters with respect to investments which are made to sustain or develop its existing transmission infrastructure. Distribution Business Overview Hydro One's distribution business consists of owning, operating and maintaining Hydro One's distribution system, which Hydro One, through Hydro One Inc., owns primarily through its wholly- owned subsidiary, Hydro One Networks Inc., the largest local distribution company in Ontario. The Company's distribution system is also the largest in Ontario. The Company's distribution business is a rate-regulated business that earns revenues mainly by charging distribution rates that are subject to approval by the OEB. The Company's distribution rates are generally determined using a performance- based model, except for the distribution rates of Hydro One Remote Communities Inc., which are set on a cost-recovery basis and do not include a return on equify. Hydro One's distribution business represented approximately 37o/o of its total assets as at December3l, 2016, and accounted for approximately 47oh of its total revenue in 2016, net of purchased power and 48o/o of its total revenue in20l5, net of purchased power. Hydro One's distribution business also includes the business of its wholly-owned subsidiary, Hydro One Remote Communities Inc., which supplies electricity to customers in remote communities in northern Ontario. Distribution revenues include distribution rates approved by the OEB and amounts to reimburse Hydro One for the cost of purchasing electricity delivered to its distribution customers. Distribution revenues also include minor ancillary service revenues, such as fees related to the joint use of the Company's distribution poles by participants in the telecommunications and cable television industries, as well as miscellaneous charges such as charges for late payments. As at December 3 I , 201 6, Hydro One's distribution assets were $9,337 million. Business Hydro One delivers electricity through its distribution network to over l 3 million residential and business customers, most of whom are located in rural areas, as well as 53 local distribution companies (including Hydro One's own distribution business). Hydro One's distribution system includes approximately 123,000 circuit kilometres of primary low- voltage distribution lines and approximately 1,000 distribution and regulating stations. Other distribution assets include poles, transformers, service centres and equipment. Hydro One's distribution system services a predominantly rural territory. As a result of the lower Exhibit No. 422 Case Nos. AVU-E-I7-- and AVU-G-17-- C.Lopez, Hydro One Schedule 3, Page 127 of 167 population density in the Company's service territory, the Company's costs to provide distribution services may be higher than those of distributors who service urban areas. Furthermore, unlike the distribution systems found in urban areas, most of Hydro One's distribution system was not designed with redundancy, to be interconnected in loops with other distribution lines, with the result that interruptions experienced at any point along a distribution line in Hydro One's network can cause all customers downstream of the interruption point to lose power. Accordingly, the reliability of Hydro One's distribution system is lower than that of local distribution companies which service urban territories that typically have redundancy built into their systems. The Company engages in vegetation management activities to maintain the reliability of Hydro One's distribution system on a preventive basis and to protect public health and safety. This consists of the trimming or removal of trees to lower the risk of contact with distribution lines, thereby reducing the risk of power outages, and preventing potential injury to the public or employees. The Company's monitoring systems assist with determining areas of priority and with system restoration. The Company relies on its local line crews for these restoration activities. Hydro One's distribution business is involved in the connection of new sources of electricity generation. including renewable energy. Hydro One invests in upgrades and modifications to its distribution system to accommodate these new sources of generation and ensure the continued reliability of its distribution network. As at December 3 I , 2016, there were approximately 15,000 small, mid-size and large embedded generators connected to Hydro One's distribution network, including approximately 14,000 generators with capacities of up to l0 kW. As at December 31,2016, Hydro One also had approximately 1,500 generators pending connection. Hydro One has played a significant role in the installation of smaft meters and the migration of distribution customers to time of use pricing in Ontario. Smart meters are regarded as an integral means of promoting a culture of conservation, and they allow customers to change their electricity consumption patterns and reduce their costs. Hydro One has completed all material activities associated with the implementation of smarl meters, and has transitioned the vast majority of its customers to time of use pricing. Acquisitions Agreement to Acquire Orillia Power In August 2016, the Company reached an agreement to acquire Orillia Power, an electricity distribution company located in Simcoe County, Ontario, for approximately $41 million, including the assumption of approximately $15 million in outstanding indebtedness and regulatory liabilities, subject to closing adjustments. The acquisition is subject to regulatory approval by the OEB. Integration of Haldimand Hydro and Woodstock Hydro In 2015, the Company acquired Haldimand Hydro and Woodstock Hydro, two Ontario-based local distribution companies. In September 2016, the Company successfully completed the integration of both entities, including the integration of employees, customer and billing information, business processes, and operations. See "General Development of the Business - Acquisitions Generally" for more information. Regulation Distribution Rates Distribution rates in Ontario are determined using a performance-based model set out in the OEB's Renewed Regulatory Frameworkfor Electricity Distributors: A Performance-Based Approach, which is Exhibit No. 423 Case Nos. AVU-E-I7-- and AVU-G-17-- C.Lopez, Hydro One Schedule 3, Page 128 of'167 sometimes referred to as the "RRF". Under the RRF, distributors in Ontario may choose one of three rate- setting methods, depending on their capital requirements: 4ft Generation Incentive Rate-setting (now known as Price Cap IR), Custom Incentive Rate-Setting, or Annual Incentive Rate-Setting Index. The RRF contemplates that a distributor will apply for the approval of its revenue requirement for an initial base year covered by the rate decision. The revenue requirement for subsequent years is determined based on a formula that accounts for inflation and certain productivity factors set by the regulator. The revenue requirement in these subsequent years is set on the assumption that the distributor is lowering its cost of service over the period covered by the rate decision due to efficiency or productivity improvements. The RRF allows the distributor to retain all or a portion of the cost savings achieved in excess of the estimate established by the regulator during the period covered by the rate decision. This allows the distributor an ability to earn more than its allowed return on equity. The RRF provides incentives for distributors to achieve certain performance outcomes, namely: customer focus, operational effectiveness, public policy responsiveness and financial performance. The OEB has indicated that customer focused outcomes and continuous performance improvements by distributors are central to the RRF framework objectives. The OEB has further indicated that distributors should develop plans that respond to customer service needs. A distributor must submit proposed performance measures as part of its application for distribution rates under the RRF. Distributors may also propose their own performance measures for approval by the OEB. In its most recent distribution application, Hydro One submitted eight additional quantitative measures relating to areas that will be the subject ofincreased spending levels over the next few years, such as pole replacements, distribution station refurbishments and vegetation management. Distributors are required to report to the OEB on their performance against the performance measures approved as part of their most recent rate decision. The OEB's review process under the RRF follows a process similar to that of a transmission rate application for the review ofthe anticipated cost ofservice for providing distribution services, other than as noted above. Once the revenue requirement for distribution services is determined, it is allocated across the distributor's customer rate classes using a methodology approved by the OEB resulting in the setting of individual rates for distribution services based on each customer rate class. Hydro One currently has l3 customer rate classes. Distribution rates in Ontario are not the same for all distributors and reflect the particular circumstances of each distributor, including its own costs of providing electricity service to its own particular customers. The OEB policy, A New Distribution Rate Design for Residential Electricity Customers, changes the current distribution rate design for residential customers (a combination of a fixed monthly rate and a variable charge) to a fixed monthly charge only. In December 2015, the OEB increased the transition period for certain customer classes of Hydro One Networks Inc. to eight years to mitigate bill impacts. Implementation will occur over the next three to seven years for Hydro One Networks Inc.'s residential customers. The OEB has also initiated a working group to consider possible changes to the design of rates for commercial industrial customers. Changes to rate design will not impact the rates revenue requirement to be collected for each customer class. Distribution Rate Applications The Company's distribution rates, other than the distribution rates of Hydro One Remote Communities Inc., are determined using a performance-based model. In March 2015, the OEB issued a decision regarding Hydro One Networks Inc.'s distribution rates for the three-year period from 2015 to2017, providing for a revenue requirement of $1,326 million for 2015, $1,430 million for2016 and $1,486 million for2017. The 2015 revenue requirement reflects an approved Exhibit No. 424 Case Nos. AVU-E-17-- and AVU-G-I7-- C.Lopez, Hydro One Schedule 3, Page 129 of 167 rate base of 56,552 million, retum on equity of 9.30% and a deemed capital structure of 60'/o debt and 40%o equity. The rates are effective as of January I in each year. On January 14,2016, the OEB issued its final decision and order approving Hydro One Nefworks Inc.'s draft rate order for 2016 rates. In December 2016, the OEB issued its decision and order approving Hydro One Networks Inc.'s distribution rates effective January 1,2017. The overall impact of this decision is a reduction of the proposed 2017 revenue requirement to approximately $1,415 million from $1,486 million. The 2017 revenue requirement reflects an approved rate base of $7,190 million, return on equity of 8.78o/o and a deemed capital structure of 60% debt and 40% equity. The overall impact of the new rates is a reduction in distribution delivery charges for most residential customers. In December 2016, the OEB approved increases to the rates charged in the service areas for the former Haldimand Hydro, Woodstock Hydro and Norfolk Hydro, effective January 2017. Hydro One Networks Inc. expects to file a distribution rate application for 2018 to 2022 in the first quarter of2017. Hydro One Remote Communities Inc.'s business is exempt from a number of sections of the Electricity Act which relate to the competitive market. For example, Hydro One Remote Communities Inc. continues to apply bundled rates to customers in remote communities. Hydro One Remote Communities Inc.'s business is operated on a break-even basis, without a return on equity included in rates. As a result, any net income or loss in the year related to the regulated operations of Hydro One Remote Communities Inc. is recorded in a regulatory variance account for inclusion in the calculation of future customer rates. For more information, see the Annual MD&A under the heading "Regulation" Conservation and Demand Management CDM requirements in Ontario require distributors to achieve specific energy savings targets by encouraging their customers to reduce their energy usage. Distributors seek to achieve these targets through a number of different initiatives, including by offering customers energy saving devices for use at home, cash rebates for the purchase ofenergy efficient light bulbs and other products. Incentive programs are also offered to small, medium, and large businesses, as well as industrial customers. Distributors are responsible for developing and submitting CDM plans and reporting on their progress towards achieving specific energy-savings targets. The IESO oversees compliance with CDM requirements in Ontario and also reimburses distributors for the costs of complying with CDM requirements. Hydro One expects that its costs of complying with CDM requirements will be fully reimbursed by the IESO. As a result, CDM- related costs that are reimbursed by the IESO are not included in Hydro One's rate applications to the OEB. Distributors in Ontario are collectively required to achieve a total of 7 TWh of electricity savings by December 31, 2020, with each local distribution company being allocated individual energy-savings targets and budgets. Targets and budgets for CDM were allocated to distributors in October 2014. Hydro One Networks Inc.'s 2015-2020 CDM energy savings target is 1,159 GWh and its CDM plan was approved by the IESO on July 8, 201 5. In December 2016, Hydro One Networks Inc.'s 2015-2020 CDM energy savings target was revised to l,221GWh to reflect the integration of the CDM targets of Norfolk Power, Haldimand Hydro and Woodstock Hydro. In December 2016, Hydro One Networks Inc. also submitted a joint CDM plan with another local distribution company to the IESO for approval. The joint target for Hydro One Networks Inc. increased by 35 GWh to 1,256 GWh by 2020. Exhibit No. 4 Case Nos. AVU-E-I7- and AVU-G-I7- i.Lop".,Hydro One 25 Schedule 3, Page 130 of 167 Capital Expenditures Hydro One's asset sustainment activities are based on an assessment of asset condition. Distribution asset renewals are underlaken when assessments indicate there is a high risk of failure and where further maintenance activities are not appropriate. Capital expenditures for the Company's distribution business in the near term are anticipated to focus on new load connections, storm damage, wood pole replacement, and system capability reinforcement. In addition, the Company expects to continue to construct new distribution lines and stations in the future in response to system growth forecasts, continued suburban community development, high load relief requirements and requirements to connect new sources of generation. The Company expects that it will spend approximately $647 million to $771 million per year over the next five years on capital expenditures relating to its distribution business. Hydro One is continuing to modernize its distribution system through the deployment of smart devices (including remotely controllable switches and breakers as well as faulted circuit indicators) as power system assets are renewed. Hydro One is also implementing a new Distribution Management System ("DMS") at its Ontario Grid Control Centre. The DMS will enable distribution components to be monitored and controlled, perform real-time analysis and determine, with greater precision, the location of equipment failures. Additional functionality is planned, in future, to allow field staff to view system conditions remotely in real-time. Smart metering data will also be used to deliver operational and asset management benefits such as better notification of outages and their scope, asset loading information and other data. For more information on future capital expenditures, see the Annual MD&A under the subheading "Capital Investments - Future Capital Investments". Competitive Conditions Hydro One's distribution service area is set out in its licence issued by the OEB. Only one distributor is permitted to provide distribution services in a service territory, and distributors have exclusive rights to provide service to new customers located within their service territory. As a result, there is very little direct competition for distribution services in Ontario, except near the borders of adjoining service territories, where a distributor may apply to the OEB to claim the right to serve new customers who are not cumently connected to its distribution grid. In March 20l6,the OEB directed all local distribution companies to eliminate load transfer arrangements by June 21,2017. Load transfer arrangements arise when a customer is within one distributor's service area but is served by a second distributor. The Company has load transfer arrangements with over 50 local distribution companies. Hydro One Networks Inc. has developed an implementation plan to eliminate load transfer arrangements. As a result, some of the Company's customers will be transferred to the adjacent local distribution companies and other customers will be added to the Company's customer base. To create more efficiency in the distribution sector, the Premier's Advisory Council on Government Assets endorsed the need for faster consolidation among local distribution companies in Ontario, which may result in competition for acquisition or merger opportunities. Potential acquirers may include strategic and financial buyers, in addition to other local distribution companies. Other Business Hydro One's other business segment consists of principally its telecommunications business, which provides telecommunications support for the Company's transmission and distribution businesses as well as certain corporate activities including a deferred tax asset. The telecommunication business is carried out by its wholly-owned subsidiary Hydro One Telecom Inc. It also offers communications and information technology solutions to organizations with broadband network requirements utilizing Hydro One Telecom Inc.'s fibre optic network to provide diverse, secure and highly reliable connectiviry. Exhibit No. 426 Case Nos. AVU-E-I7-- and AVU-G-I7-- C.Lopez, Hydro One Schedule 3, Page l3l of 167 Hydro One Telecom Inc. is not regulated by the OEB. However, Hydro One Telecom Inc. is registered with the Canadian Radio-television and Telecommunications Commission as a non-dominant, facilities- based carrier, providing broadband telecommunications services in Ontario with connections to Montreal, Quebec, Buffalo, New York and Detroit, Michigan. The other business segment represented approximately l2Yo of Hydro One's total assets as at December 31, 2016, and accounted for approximately 2o/o of its total revenue, net of purchased power in each of 2016 and2015. The deferred tax asset arose on the transition from the provincial payments in lieu of tax regime to the federal tax regime in connection with the Company's initial public offering and reflects the revaluation of the tax basis of Hydro One's assets to fair market value. First Nations and M6tis Communities Hydro One believes that building and maintaining respectful, positive and mutually beneficial relationships with First Nations and Mdtis communities across the province is important to achieving the Company's corporate objectives. Hydro One is committed to working with First Nations and Mdtis communities in a spirit of cooperation, partnership and shared responsibility. Hydro One's equity partnership with the Saugeen Ojibway Nation in respect of the Bruce-to-Milton transmission line demonstrates the Company's commitment to these principles. In keeping with the Company's First Nations and Mdtis Relations Policy, Hydro One's First Nations and M6tis Relations team provides guidance and advice to support the Company in developing and advancing positive relationships. Hydro One also has several programs related to First Nations and Mdtis communities and their citizens. These include educational and training opportunities which provide opportunities for work terms, First Nations and Mdtis procurement partnership agreements along with community investments, customer support and outreach. Together, Hydro One Networks Inc. and Hydro One Remote Communities Inc. serve approximately 90 First Nation communities. The Company's Health, Safety, Environment and First Nations & Mdtis Committee of the Board is responsible for assisting the Board in discharging the Board's oversight of responsibilities relating to effective occupational health and safefy and environmental policies and practices at Hydro One, and its relationship with First Nations and Mdtis communities. Outsourced Services To gain efficiencies and cost reductions, Hydro One has outsourced certain non-core functions, including facilities management services with respect to its stations and other facilities, and certain back-office services such as information technology, payroll, supply chain, call centre and accounting services. The Company's back-office services and call centre services are provided by a third party service provider under an agreement that expires on December3l,2019 for back-office services, and on February28, 201 8 for call centre services. The Company has an option to renew the agreement for two additional terms of approximately one year each. The Company's facilities management services are provided by a third party service provider under an agreement that expires on December31,2024 with an option for the Company to renew the agreement for an additional term of three years. Employees As at December 31,2016, Hydro One had approximately 5,500 regular employees and over 2,000 non- regular employees province-wide comprised of a mix of skilled trades, engineering, professional, managerial and executive personnel. Hydro One's regular employees are supplemented primarily by accessing a large external labour force available through arrangements with the Company's trade unions for variable workers, sometimes referred to as "hiring halls", and also by access to contract personnel. The hiring halls offer Hydro One the ability to access highly trained and appropriately skilled workers on a project-by-project basis. This provides the Company with more flexibility to address seasonal needs and unanticipated changes to its budgeted work programs. The Company also offers apprenticeship and Exhibit No. 427 Case Nos. AVU-E-I7-- and AVU-G-I7-- C.Lopez, Hydro One Schedule 3, Page 132 of \67 technical training programs to ensure that future staffing needs will continue to be met. For more information on employees, see the Annual MD&A under the heading "Hydro One Work Force". Health, Safety and Environmental Management Hydro One has an integrated Health, Safety and Environment Management System that includes key elements for the successful minimization of risk and continued performance improvements. Health, safety and environmental hazards and risks are identified and assessed and controls are implemented to mitigate significant risks. The Company has policies in place regarding Health and Safety, Environment, Workplace Violence and Harassment and Public Safety. Hydro One Networks Inc. is a designated "Sustainable Electricity Company" by the Canadian Electricity Association. The brand demonstrates Hydro One's commitment to responsible environmental, social and economic practices, and to the principles of sustainable development. Given the nature of the work undertaken by Hydro One employees, health and safety remains one of the Company's top priorities. The Company is committed to creating and maintaining a safe workplace which is one of Hydro One's stated core values, and maintaining safety through a concentrated focus on the elimination of serious incidents or "near-misses" which have the potential to cause serious injuries. The Company has developed and is continuing to develop a number of programs and initiatives for accident prevention and to minimize the risk of injury to the public associated with its facilities and operations. Measures are in place to monitor, on a regular basis, health, safety and environment performance using proactive and reactive measures and/or qualitative and quantitative measures. Since 2004,the evolution of Hydro One's recordable rate, its key health and safety perfornance measure, has seen a reduction of approximately 85% in the number of recordable rate incidents. All measures are monitored by management and by the Health, Safety, Environment and First Nations & Mdtis Committee. Management compensation has been tied, in part, to success in achieving annual health and safety performance targets. A program allowing for an effective early and safe return to work has allowed the Company to ensure that, when injuries occur, employees recover and return to the workplace as soon as possible. ln 2016, Hydro One continued with its "Journey lo Zero" safety initiative that began in 2009. This initiative compares Hydro One to other companies to identiff performance gaps. Safety perception assessments were completed in 2009,2013 and 20 15. The assessment identified opportunities for improvement and foms the development of new health and safety initiatives using cross-functional teams from across the province. Environmental Regulation Hydro One is subject to extensive federal, provincial and municipal regulation relating to the protection of the environment that governs, among other things, environmental assessments, discharges to water and land and the generation, storage, transportation, disposal and release of various hazardous substances. Estimated environmental liabilities are reviewed annually or more frequently if significant changes in regulation or other relevant factors occur. Estimated changes are accounted for prospectively. Permits and Approvals The Company is required to obtain and maintain specified permits and approvals from federal, provincial and municipal authorities relating to the design, construction and operation of new and upgraded transmission and distribution facilities. Examples include environmental assessment approvals, permits for facilities to be located in parks or other regulated areas, water crossing permits, and approvals to discharge to air and water. Some projects may require environmental approvals from the federal Exhibit No. 428 Case Nos. AVU-E-17-- and AVU-G-I7-- C.Lopez, Hydro One Schedule 3, Page 133 of 167 government. Interconnections with neighbouring utilities in other provinces and states also require federal approval and will be subject to federal regulatory review. In general, larger projects are subject to an individual environmental assessment process, pursuant to the Environmental Assessment Act (Ontario). The majority of approvals fall under a class environmental assessment process which provides for more streamlined approvals. The scope, timing and cost of environmental assessments are dependent on the scale and type of project, the location (urban versus rural), the environmental sensitivity of affected lands and the significance of potential environmental effects. Regulation of Releases Federal, provincial and municipal environmental legislation regulates the release of specific substances into the environment through the prohibition of discharges that will or may have an adverse effect on the environment, which can include liquids, gasses and noise. Releases occur in the course of the Company's normal operations. Accordingly, Hydro One has spill, leak prevention and leak mitigation programs involving the testing, replacement, repair and installation of containment systems including re-gasketting of transformers and sulphur-hexafluoride-filled equipment. In addition, the Company has an emergency response capability which the Company believes is sufficient to minimize the environmental impact of spills and to comply with its legal obligations. Pursuant to the Climate Change Mitigation and Low-carbon Economy Act, 2016, the Province introduced a cap and trade program in Ontario beginning January 1,2017 . For more information, see "The Electricity Industry in Ontario - Recent Legislative Amendments Affecting the Electricity Industry Generally - Climate Change Mitigation and Low-carbon Economy Act, 2016". Hazardous Substances Hydro One manages a number of hazardous substances, such as PCBs, herbicides, and wood preservatives. In addition, some facilities have substances present which are designated for special treatment under occupational health and safety legislation, such as asbestos, lead and mercury. The Company has environmental management programs in place to deal with PCBs, herbicides, asbestos, and other hazardous substances. Land Assessment and Remediation Hydro One has a pro-active land assessment and remediation program in place to identiff and, where necessary, remediate historical contamination that has resulted from past operational practices and uses of certain long-lasting chemicals at the Company's facilities. These programs involve the systematic identification of contamination at or from these facilities and, where necessary, the development of remediation plans for the Company's properties and affected adjacent private properties. As at December 31,2016, future consolidated expenditures related to Hydro One's land assessment and remediation program were estimated at approximately $61 million, and undiscounted liabilities were estimated at approximately $66 million. These consolidated expenditures are expected to be spent over the period ending 2032. Addilional acquisitions could add to land assessment and remediation expenditures. The consolidated expenditures on this program for 2016 were approximately $9 million. These costs are expected to be recovered in the Company's transmission and distribution rates. Insurance Hydro One maintains insurance coverage, including liability, all risk property, boiler and machinery and directors' and officers' insurance. The Company also maintains other insurance coverage that is required by law, covering risks such as automobile liability, pesticide liability and aircraft liability. The Company does not have insurance for damage to its transmission and distribution wires, poles or towers located Exhibit No. 429 Case Nos. AVU-E-I7-- and AVU-G-I7-- C. Lopez, Hydro One Schedule 3, Page 134 of 167 outside transmission and distribution stations, including damage caused by severe weather, other natural disasters or catastrophic events or for environmental remediation costs. The OEB has generally permitted the recovery of costs associated with extreme weather events, such as the ice storm that occurred in 1998. Reorganizations In 2015, prior to the closing of the initial public offering of Hydro One Limited, Hydro One completed a series of transactions resulting in, among otherthings, the acquisition by Hydro One Limited of all of the issued and outstanding shares of Hydro One Inc. and the issuance of new common shares and preferred shares of Hydro One Limited to the Province. The Province then sold a portion of its common shares of Hydro One Limited pursuant to the initial public offering. A series of pre-closing steps occurred, including: On October 31,2015, Hydro One Inc. repurchased its existing preferred shares held by the Province for cancellation at a price equal to the redemption price of the preferred shares (being equal to approximately $323 million) satisfied by the issuance to the Province of common shares of Hydro One Inc. having an aggregate fair market value equal to the price to be paid for the preferred shares. Allof the issued and outstanding common shares of Hydro One Inc. were acquired by Hydro One Limited in retum for the issuance to the Province of 12,197,500,000 common shares and 16,720,000 Series I preferred shares of Hydro One Limited. Hydro One Inc. and certain of its subsidiaries were required to pay a $2.6 billion "departure tax" to the Ontario Electricity Financial Corporation as a consequence of the initial public offering. The outstanding common shares of Hydro One Limited were consolidated such that 595,000,000 common shares were issued and outstanding immediately prior to the closing of the initial public offering. Under applicable Canadian securities laws, the acquisition of all of the issued and outstanding shares of Hydro One Inc. was considered a "significant acquisition". Hydro One Limited filed a business acquisition report in respect of the acquisition on January 14,2016. See also "General Development of the Business" for more information. RISK FACTORS A discussion of Hydro One Limited's risk factors can be found under the heading "Risk Management and Risk Factors" in the Annual MD&A. DIVIDENDS The Company did not declare or pay cash dividends in 2015. In 2016, the Company declared and paid cash dividends to common shareholders as follows: I This was the lirst common share dividend declared by the Company following the completion of its initial public ofl'ering in November 2015. The $0.34 per share dividend included $0.13 for the post-IPO period from November 5 to December 31, 2015, and $0.2 I for the quarter ended March 3 I , 201 6. Exhibit No. 4 Case Nos.

The dividend represents payment for the first quarter ending March 31,2017 . ln2016, the Company declared and paid cash dividends to the Province, the sole holder of the Series I preferred shares as follows: On February 9, 2017, the Board declared a dividend of $0.265625 per share on each of its Series I preferred shares and it was paid on February 21,2017. Dividend Policy The Board has established a dividend policy pursuant to which Hydro One Limited expects to pay an annualised dividend amount on its common shares, based on atarget payout ratio of 70ohto 80% of net income. The amount and timing of any dividends payable by Hydro One Limited will be at the discretion of the Board and will be established on the basis of Hydro One's results of operations, maintenance of its deemed regulatory capital structure, financial condition, cash requirements, the satisfaction of solvency tests imposed by corporate laws for the declaration and payment of dividends and other factors that the Board may consider relevant. The preferred shares of Hydro One Limited are entitled to a preference over the common shares with respect to the payment of dividends. Other than the foregoing, there is currently no restriction that would prevent the Company from paying dividends at current levels. For more information on dividends, see the notes to the audited consolidated financial statements of Hydro One Limited as at and for the years ended December 31,2016 and 2015 under the headings "Dividends" and "Subsequent Events". Dividend Reinvestment Plan On February ll, 2016, the Board approved the creation of a Dividend Reinvestment Plan which is currently in place. The Dividend Reinvestment Plan enables eligible shareholders to have their regular quarterly cash dividends automatically reinvested in additional Hydro One common shares acquired on the open market.

PROMOTERS Hydro One Inc. has taken the initiative in founding and organizing Hydro One Limited and may therefore be considered a promoter of Hydro One Limited for the purposes of applicable securities legislation. In connection with a series of pre-closing transactions completed in connection with the initial public offering of Hydro One Limited, on October 31,2015, Hydro One Limited acquired all of the issued and outstanding common shares of Hydro One Inc. from the Province in exchange for the issuance to the Province of 16,720,000 Series I preferred shares and 12,197,500,000 common shares. See "Corporate Structure - Corporate Structure and Subsidiaries", "General Development of the Business" and "Business of Hydro One - Reorganizations". Although the Province was identified as a promoter of Hydro One for purposes of the initial public offering, as a result of the entering into of the Govemance Agreement and completion of the initial public offering, Hydro One no longer believes the Province is a promoter of Hydro One. AGREEMENTS WITH PRINCIPAL SHAREHOLDER In connection with the November 2015 completion of the initial public offering of Hydro One Limited, on November 5,2015, Hydro One and the Province entered into: the Governance Agreement to address the Province's role in the governance of Hydro One Limited; and the Registration Rights Agreement to provide the Province with the right to require Hydro One Limited to facilitate future secondary offerings of common shares or preferred shares owned or controlled by the Province.

In connection with the initial public offering of Hydro One Limited, the Company entered into the Governance Agreement and the Registration Rights Agreement with the Province. See "Agreements with Principal Shareholder". Transfer Orders The transfer orders pursuant to which Hydro One Inc. acquired Ontario Hydro's electricity transmission, distribution and energy services businesses as of April 1, 1999, did not transfer certain assets, rights, liabilities or obligations where the transfer would constitute a breach of the terms of any such asset, right, liability or obligation or a breach ofany law or order (the "trust assets"). The transfer orders also did not transfer title to assets located on Reserves, which assets are held by the Ontario Energy Financial Corporation. For more information, see the Annual MD&A under the subheading "Risk Management and Risk Factors - Risk from Transfer of Assets Located on Reserves". Hydro One is obligated under the transfer orders to manage both the trust assets (until it has obtained all consents necessary to complete the transfer of title to these assets to Hydro One) and the assets otherwise retained by the Ontario Electricity Financial Corporation that relate to Hydro One's businesses. Hydro One has entered into an agreement with the Ontario Electricity Financial Corporation under which it is obligated, in managing these assets, to take instructions from the Ontario Electricity Financial Corporation if Hydro One's actions could have a material adverse effect on the Ontario Electricity Financial Corporation. The Ontario Electricity Financial Corporation has retained the right to take control of and manage the assets, although it must notiff and consult with Hydro One before doing so and must exercise its powers relating to the assets in a manner that will facilitate the operation of Hydro One's businesses. The consent of the Ontario Electricity Financial Corporation is also required prior to any disposition of these assets. The Province also transferred officers, employees, assets, liabilities, rights and obligations of Ontario Hydro in a similar manner to its other successor transferees. These transfer orders include a dispute resolution mechanism to resolve any disagreement among the various transferees with respect to the transfer of specific assets, liabilities, rights or obligations. The transfer orders do not contain any representations or warranties from the Province or the Ontario Electricity Financial Corporation with respect to the transferred officers, employees, assets, liabilities, rights and obligations. Furthermore, under the Electricity Act, the Ontario Electricity Financial Corporation was released from liability in respect of all assets and liabilities transferred by the transfer orders, except for liability under Hydro One's indemnity from the Ontario Electricity Financial Corporation. The parties, with the consent of the Minister of Finance, agreed to terminate such indemnity effective October 31,2015. By the terms of the transfer orders, each transferee indemnifies the Ontario Electricity Financial Corporation with respect to any assets and liabilities related to that transferee's business not effectively transferred, and is obligated to take all reasonable measures to complete the transfers where the transfers were not effective. Hydro One has indemnified the Ontario Electricity Financial Corporation in respect of the damages, losses, obligations, liabilities, claims, encumbrances, penalties, interest, taxes, deficiencies, costs and Exhibit No. 449 Case Nos. AVU-E-I7-- and AVU-G-I7-- C. Lopez, Hydro One Schedule 3, Page 154 of 167 expenses arising from matters relating to the Company's business and any failure by Hydro One to comply with its obligations to the Ontario Electricity Financial Corporation under agreements dated as of April l,1999. These obligations include obligations to employ the employees transferred to Hydro One under the transfer orders, make and remit employee source deductions (including tax withholding amounts, and employer contributions), manage the real and personal properlies which the Ontario Electricity Financial Corporation continues to hold in trust or otherwise and take any necessary action to transfer all of these properties to the Company, to pay realty taxes and other costs, provide access to books and records and to assume other responsibilities in respect of the assets held by the Ontario Electricity Financial Corporation in trust for the Company. Departure Taxes By virtue of being wholly owned by the Province, Hydro One was exempt from tax under the Income Tax Act (Canada) and the Taxation Act, 2007 (Ontario). However, under the Electricity Act, Hydro One was required to make payments in lieu of tax to the Ontario Electricity Financial Corporation. The payments in lieu of tax were, in general, based on the amount of tax that Hydro One would otherwise be liable to pay under the Income Tax Act (Canada) and the Taxation Act, 2007 (Ontario) if it was not exempt from taxes under those statutes. In connection with the initial public offering of Hydro One Limited, Hydro One's exemption from tax under the Income Tax Act (Canada) and the Tuation Act, 2007 (Ontario) ceased to apply. Under the Income Tax Act (Canada) and the Tmation Act, 2007 (Ontario), Hydro One was deemed to have disposed of its assets immediately before it lost its tax exempt status resulting in Hydro One making payments in lieu of tax under the Electricity Act totalling $2.6 billion in respect thereof, calculated by reference to the Income Tax Act (Canada) ("departure tax"). Hydro One Inc. also paid the Ontario Electricity Financial Corporation approximately $0.2 billion in additional payments in lieu of tax in connection with the initial public offering and approximately $0.1 billion in other payments in lieu of tax instalments. For a discussion of the departure tax and the related financial implications on the Company, see the Annual MD&A under the heading "Related Parfy Transactions". MATERIAL CONTRACTS The following are the only material contracts, other than those contracts entered into in the ordinary course of business, which Hydro One Limited has entered into since the beginning of the last financial year, or entered into prior to such date but which contract is still in effect: (a) the underwriting agreement (the "20l6 Underwriting Agreement") dated April 7,2016, between Hydro One Limited, the Province and a syndicate of underwriters pursuant to which the underwriters agreed to purchase, and the Province agreed lo sell 72,434,800 common shares (such number of shares subsequently increased to an aggregate of 83,300,000 common shares) of Hydro One Limited at a price of $23.65 per share.

The Company is not subject to any material regulatory actions. Hydro One Inc., Hydro One Networks, Hydro One Remote Communities Inc., and Norfolk Power Distribution Inc. are defendants in a class action suit in which the representative plaintiff is seeking up to $125 million in damages related to allegations of improperbilling practices. A certification motion in the class action is pending. Due to the preliminary stage of legal proceedings, an estimate of a possible loss related to this claim cannot be made. In connection with the reorganization of Ontario Hydro, Hydro One Inc. succeeded Ontario Hydro as a parry to various pending legal proceedings relating to the businesses, assets, real estate and employees transferred to it. Hydro One Inc. also assumed responsibility for future claims relating to the businesses, assets, real estate and employees acquired by Hydro One Inc. and arising out of events occurring prior to, as well as after, April l, 1999.|n addition to claims assumed by the Company, it is, from time to time, named as a defendant in legal actions arising in the normal course of business.
