2018-2019 MULTI-YEAR BUDGET SUMMARY WATER There are no operating budget amendments required for the Water budget as all of the budget pressures have been accommodated through efficiencies in operations or decreased transfers to reserves (Clean Water and Wastewater Fund staffing). There are five (5) capital budget amendments for this service area resulting in a $14.6 million decrease in the 2016-2019 approved budget and a $10.1 million increase to the 2020-2025 capital forecast adopted in the 2016-2019 capital budget. These budget amendments are detailed beginning on page 21. In 2017, Civic Administration successfully applied for funding under the Clean Water and Wastewater Fund (CWWF) providing additional funding in the amount of $5.2 million towards water infrastructure. These previously approved budget changes are reflected in this document. Applications for Phase 2 of the program are anticipated in the fourth quarter of 2017. Details of projects eligible for Phase 2 funding have not yet been made available; therefore, the 2018 budget update does not include the impact of Phase 2 of the CWWF program. Phase 2 of the CWWF will substantially change the capital program (the 10 year forecast, the regulatory Financing Plan, and 20 year infrastructure plan). These plans and forecasts will require updating after the Phase 2 funding program is understood, applied for and approved in 2018. The capital program changes due to CWWF will also impact future operating budgets. Phase 1 of CWWF, totaling $41.4 million, is being managed as priority work, delaying other priorities. Hiring is currently underway for the new positions approved in second quarter of 2017 to respond to the long-term nature of the program and to address near-term succession planning challenges. Rebuilding capacity for the future, meeting the needs of the Rapid Transit program and responding to new technologies introduced through the infrastructure program will also be considered. Page 5

The largest pressure facing the 2018-2019 Water Operating budget is the additional resourcing approved on June 13, 2017 to undertake the work required under the Clean Water and Wastewater Fund (CWWF) program. This increase to staff costs ($684 thousand and $561 thousand respectively) is being funded through the decreased reserve and reserve fund requirements in the future because of the 75% funding provided for capital works. Offsetting these increases are reductions in costs in three main areas, insurance premiums, utility costs (Hydro and Natural Gas based on 2017 estimates), and Financial Expenses. The change in Financial Expenses is primarily in transfers to reserves and reserve funds with annual contributions being reduced by $507 thousand in 2018 and $498 thousand in 2019 due to decreased future reserve and reserve fund requirements as a result of CWWF program funding.

RECONCILIATION OF TABLED WATER BUDGET TO PUBLIC SECTOR ACCOUNTING BOARD (PSAB) FINANCIAL STATEMENT BUDGET Ontario municipalities must adhere to Public Sector Accounting Board (PSAB) accounting standards and reporting requirements, however, with the introduction of PS1200 in 2009, the Province of Ontario enacted a regulation, Ontario Regulation 284/09, allowing for certain items to be excluded from their budgets, as long as it was disclosed. Typical PSAB items, such as costs related to amortization expense, postemployment benefit expense and solid waste landfill closure and post-closure expense can be excluded, however, the regulation does require that the municipality report to Council on the impact of these excluded costs prior to budget approval. The regulation requires that the report contain information regarding: 1. An estimate of the change in the accumulated surplus of the municipality to the end of the year resulting from the exclusion of any of those expenses; and 2. An analysis of the estimated impact of the exclusion of any of those expenses on the future tangible capital asset funding requirements of the municipality or local board. London s 2018 and 2019 draft Water operating budget as tabled, excludes the following expenses: 1. Expenses for the amortization of tangible capital assets, estimated to be $14.4 million for 2018 and $15.0 million for 2019, are excluded. The budget does include reserve fund contributions of $11.3 million for 2018 and $12.2 million for 2019 and pay as you go contributions of $20.1 million for 2018 and $20.2 million for 2019 for capital asset additions. 2. The budget does not contain the current year s post-employment benefit expense for early retirement and accrued sick leave, estimated to total $135 thousand for 2018 and $136 thousand for 2019, for employees that are eligible for these benefits. The Corporation's consolidated liability as at December 31, 2016 was $149.2 million. Reserve fund balances as of December 31, 2016 of $18.7 million are available to offset this obligation. 3. The City also makes contributions to an additional corporate reserve to offset the liabilities created from the post-employment expenses (point 2 above) and landfill closure and post-closure expenses depending upon generated surpluses, including personnel cost savings. The balance in this corporate reserve as of December 31, 2016 was $62.5 million. If the above items were included in the 2018 and 2019 budgets, the projected annual PSAB surplus would decrease. Table 1 on the following page shows the 2018 and 2019 draft Water operating budgets and the 2017 approved revised budget and Table 2 reconciles the surplus in PSAB format to the tabled Water operating budgets.

Timing change to have the construction for this project done in conjunction with Transportation project TS1355 in the same area. Aligning the project schedules is beneficial to the City by reducing overall costs and causing less disruption to the public with lane/road closures. The reduction in these measures greatly outweighs the very small risk that the watermain breaks during 2019. The current project budget assumes efficiencies of completing the Watermain Replacement at the same time as the Transportation project. Completing the project in advance of Transportation would cause the project budget to approximately double. Page 25

2018-2019 MULTI-YEAR BUDGET SUMMARY WASTEWATER & TREATMENT There are no operating budget amendments required for the Wastewater & Treatment budget as all of the budget pressures have been accommodated through efficiencies in operating areas or decreased transfer to reserves & reserve funds (Clean Water and Wastewater Fund staffing). There are two (2) capital budget amendments for this service area resulting in a $1.7 million decrease in the 2016-2019 approved budget. These budget amendments are detailed beginning on page 47. There is also a $2.7 million increase to the 2020-2025 capital forecast adopted in the 2016-2019 approved budget. In 2017, Civic Administration successfully applied for funding under the Clean Water and Wastewater Fund (CWWF) providing additional funding in the amount of $25.6 million towards Wastewater & Treatment infrastructure. These previously approved budget changes are reflected in this document. Applications for Phase 2 of the program are anticipated in the fourth quarter of 2017 and will include the funding required to undertake the Lake Erie phosphorus reduction Domestic Action Plan s municipal actions for the City of London. Details of projects eligible for Phase 2 funding have not yet been made available; therefore, the 2018 budget update does not include the impact of Phase 2 of the CWWF program. Phase 2 of the CWWF will substantially change the capital program (the 10 year forecast, the regulatory Financing Plan and 20 year infrastructure plan). These plans and forecasts will require updating after the Phase 2 funding program is understood, applied for and approved in 2018. The capital program changes due to CWWF will also impact future operating budgets. Phase 1 of CWWF, totaling $41.4 million, is being managed as priority work, delaying other priorities. Hiring is currently underway for the new positions approved in the second quarter of 2017 to respond to the long-term nature of the program and to address near-term succession planning challenges. Rebuilding capacity for the future, meeting the needs of the Rapid Transit program and responding to new technologies introduced through the infrastructure program will also be considered. Page 32

The largest pressure facing the 2018-2019 Wastewater & Treatment Operating budget is the additional resourcing approved on June 13, 2017 to undertake the work required under the Clean Water and Wastewater Fund (CWWF) program. This increase to staff costs ($1.5 million and $1.25 million respectively) is being funded through the decreased reserve & reserve fund requirements in the future because of the 75% funding provided for capital works. Offsetting these increases are reductions in costs in three main areas; insurance premiums, utility costs (Hydro and Natural Gas based on 2017 estimates), and Financial Expenses. The change to Financial Expenses is primarily in transfers to reserves and reserve funds with annual contributions being reduced by $1.26 million in 2018 and $1.1 million in 2019 due to decreased future reserve and reserve fund requirements as a result of CWWF program funding.

RECONCILIATION OF TABLED WASTEWATER & TREATMENT BUDGET TO PUBLIC SECTOR ACCOUNTING BOARD (PSAB) FINANCIAL STATEMENT BUDGET Ontario municipalities must adhere to Public Sector Accounting Board (PSAB) accounting standards and reporting requirements, however, with the introduction of PS1200 in 2009, the Province of Ontario enacted a regulation, Ontario Regulation 284/09, allowing for certain items to be excluded from their budgets, as long as it was disclosed. Typical PSAB items, such as costs related to amortization expense, postemployment benefit expense and solid waste landfill closure and post-closure expense can be excluded, however, the regulation does require that the municipality report to Council on the impact of these excluded costs prior to budget approval. The regulation requires that the report contain information regarding: 1. An estimate of the change in the accumulated surplus of the municipality to the end of the year resulting from the exclusion of any of those expenses; and 2. An analysis of the estimated impact of the exclusion of any of those expenses on the future tangible capital asset funding requirements of the municipality or local board. London s 2018 and 2019 draft Wastewater operating budget as tabled, excludes the following expenses: 1. Expenses for the amortization of tangible capital assets, estimated to be $43.6 million for 2018 and $45.5 million for 2019, are excluded. The budget does include reserve fund contributions of $25.6 million for 2018 and $24.9 million for 2019 and pay as you go contributions of $18.1 million for 2018 and $20.8 million for 2019 for capital asset additions. 2. The budget does not contain the current year s post-employment benefit expense for early retirement and accrued sick leave, estimated to total $257 thousand for 2018 and $257 thousand for 2019, for employees that are eligible for these benefits. The Corporation's consolidated liability as at December 31, 2016 was $149.2 million. Reserve fund balances as of December 31, 2016 of $18.7 million are available to offset this obligation. 3. The City also makes contributions to an additional corporate reserve to offset the liabilities created from the post-employment expenses (point 2 above) and landfill closure and post-closure expenses depending upon generated surpluses, including personnel cost savings. The balance in this corporate reserve as of December 31, 2016 was $62.5 million. If the above items were included in the 2018 and 2019 budgets, the projected annual PSAB surplus would decrease. Table 1 on the following page shows the 2018 and 2019 draft Wastewater operating budgets and the 2017 approved revised budget and Table 2 reconciles the surplus in PSAB format to the tabled Wastewater operating budgets.

Estimated based on 9.45% of capital expenditure budget, based on 2016 actuals. 3) Represents the annual writedown of the tangible capital assets over the useful life of the asset. Estimated 4.35% annual increase based on 2009-2016 actuals. 4) Contributed tangible capital assets are tangible capital assets that become the ownership of the City when a subdivision is assumed by the City. These assets are recognized at fair market value during the year of assumption. Estimate based on 6 year average of actuals. 5) When an asset is replaced prior to the end of its useful life, an adjustment must be made to expense the remaining book value. Amount fluctuates from year to year. Estimate based on 5 year average of actuals from 2012-2016. 6) Transactions recorded directly to reserve funds must be accounted for through the operating or capital fund. This includes recognition of development charge levies and federal gas tax earned in the year. 7) Represents the annual change in the estimated future costs of employee benefits. Estimate based on 8 year average. Page 46
