SIGNIFICANT ACCOUNTING POLICIES	2. SIGNIFICANT ACCOUNTING POLICIES The Company’s significant accounting policies at December 31, 2017 are described in note 2 to the Annual Financial Statements. There have been no significant changes to these policies, other than those noted below. a) Accounting pronouncements adopted in 2018 Statement of cash flows – presentation of restricted cash In November 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-18 Income statement classification of net pension benefit costs In March 2017, the FASB issued ASU 2017-07 non-service Income taxes on intra-entity transfers of assets other than inventory In October 2016, the FASB issued ASU 2016-16 Revenue recognition In May 2014, the FASB issued ASU 2014-09 2015-14, 2016-08, 2016-10, 2016-11, 2016-12 2016-20, 2014-09. Revenues Previously, for non-essential non-essential non-essential non-essential Previously, for distribution agreements where the return rights were not limited and were outside the Company’s control, the Company deferred revenue until the product was sold to an end customer. Under the new revenue recognition standard, the Company recognizes revenue upon delivery to the distributor for products that are not expected to be returned. Contract costs Previously, the Company expensed as incurred certain costs incurred to obtain and fulfill a contract with a customer, including commissions paid to the Company’s internal salesforce and customer activation costs for customers under multi-year cloud contracts. Under the new revenue recognition standard, incremental costs incurred to obtain a contract, as well as costs to fulfill a contract must be deferred and amortized over the expected period that the related performance obligation is satisfied. The Company has elected to apply a practical expedient under the guidance and expenses costs to obtain a contract as incurred, if the amortization period would have been one year or less. For the Company’s On-Site For the Company’s recurring Cloud segment, a typical solution of hardware, software, and installation, training and support is provided to a customer under a monthly recurring billing model. Contract fulfillment costs such as installation costs and incremental costs to obtain the contract such as commissions paid to the internal salesforce are generally incurred at the outset of the contract. As a result, under the new revenue recognition standard, the Company now defers these costs over the term of the contract, plus any additional expected renewal periods. Summary of changes As a result of the above accounting policy changes relating to revenue recognition, at January 1, 2018 the Company recorded a decrease in inventory of $1.2, a decrease in current deferred revenue of $11.9, a decrease in the long-term portion of deferred revenue of $7.6 and an increase in shareholders’ equity of $18.3 on its consolidated balance sheet. The effect of the adoption on the Company’s results of operations for the three and nine months ended September 30, 2018 was not material. As a result of the above accounting policy changes relating to contract costs, at January 1, 2018 the Company recorded a contract asset of $19.0 and an increase in shareholders’ equity of $19.0. The effect of the adoption on the Company’s results of operations for the three and nine months ended September 30, 2018 was not material. In addition, there was a decrease to the Company’s net deferred tax asset of $9.2 and a corresponding decrease to shareholders’ equity of $9.2 to account for the tax effect of the above changes. Disaggregation of revenues The Company’s segmented disclosures included in note 18 disaggregate the Company’s revenues by segment, product and services and by geography. For the On-Site Contract assets and liabilities The Company’s deferred contract costs at September 30, 2018 of $25.2 are included in other non-current non-current b) Accounting pronouncements issued but not yet adopted Leases In February 2016, the FASB issued ASU 2016-02 2018-10, 2016-02. right-of-use Credit losses on financial instruments In June 2016, the FASB issued ASU 2016-13 c) Reclassification Certain prior period amounts on the consolidated statement of operations have been reclassified for consistency with the current period presentation.

A considerable amount of judgment is required in order to make this assessment including a detailed analysis of the aging of the lease receivables, the current creditworthiness of our customers and an analysis of historical bad debts and other adjustments. If there is a deterioration of a major customer’s creditworthiness or actual defaults are higher than historical experience, the estimate of the recoverability of amounts due could be adversely affected. The Company reviews in detail the allowance for doubtful accounts on a quarterly basis and adjusts the allowance estimate to reflect actual portfolio performance and any changes in future portfolio performance expectations. The amount of gross sales-type leases individually and collectively evaluated for impairment is as follows: September 30, 2018 December 31, 2017 Individually evaluated for impairment Sales-type leases individually evaluated for impairment, gross $ 1.5 $ 3.2 Allowance against sales-type leases individually evaluated for impairment (0.2 ) (1.4 ) Sales-type leases individually evaluated for impairment, net $ 1.3 $ 1.8 Collectively evaluated for impairment Sales-type leases collectively evaluated for impairment, gross $ 27.9 $ 41.6 Allowance against sales-type leases collectively evaluated for impairment (0.5 ) (0.9 ) Sales-type leases collectively evaluated for impairment, net $ 27.4 $ 40.7

Additional details on the 2017 Credit Facilities are included in note 13 to the Annual Financial Statements. 2018 Debt Prepayments In May 2018, the Company repaid $45.4 of its term loans, using proceeds from the divestiture of DeTeWe and settlement of the non-interest-bearing 2017 Credit Facilities On March 9, 2017, Mitel refinanced its senior secured credit facilities. The credit facilities were initially comprised of a $150.0 Term Loan and a $350.0 revolving credit facility. Proceeds of $150.0 from the Term Loan along with $95.0 initially drawn on the revolving credit facility and cash on hand, were used to repay the remaining principal and accrued interest outstanding under the prior credit facilities, as well as fees and expenses related to the new financing. On September 25, 2017, Mitel amended its senior secured credit facilities to allow for a $300.0 Incremental Term Loan. The Incremental Term Loan, along with amounts drawn on the revolving credit facility and cash on hand from the combined company were used to finance the acquisition of ShoreTel, as described in note 3. The 2017 Credit Facilities, as amended, contain affirmative and negative covenants, including: (a) periodic financial reporting requirements, (b) a maximum Leverage Ratio and a minimum Interest Coverage Ratio (the ratio of Consolidated EBITDA to Consolidated Interest Expense, both as defined in the credit facility) (c) limitations on the incurrence of subsidiary indebtedness and also the borrowers themselves, (d) limitations on liens, (e) limitations on investments, and (f) limitations on the payment of dividends and repurchases of shares. The Company was in compliance with these covenants at September 30, 2018. The maximum Leverage Ratio is as follows: Fiscal Quarters Ending Maximum Consolidated March 31, 2017 through June 30, 2017 3.50 July 1, 2017 through June 30, 2018 4.25 July 1, 2018 through September 30, 2018 3.75 October 1, 2018 through December 31, 2018 3.50 January 1, 2019 and thereafter 3.25 The maximum Leverage Ratio and actual Leverage Ratio are as follows: Period Ending Maximum Actual March 31, 2017 3.50 1.17 June 30, 2017 3.50 1.32 September 30, 2017 4.25 3.52 December 31, 2017 4.25 3.53 March 31, 2018 4.25 3.00 June 30, 2018 4.25 2.47 September 30, 2018 3.75 2.09 The minimum Interest Coverage Ratio throughout the term of the credit facility is 3.00. The Interest Coverage Ratio at September 30, 2018 was 5.86. Other 2017 Debt Prepayments In March 2017, prior to the refinancing, the Company repaid $338.1 on its prior credit facilities using proceeds from the divestiture of the Mobile business unit, as described in note 4 to the Annual Financial Statements. In addition, in January 2017 the Company made prepayments of $22.6 on its term loan.

PENSION PLANS

PENSION PLANS	9 Months Ended

PENSION PLANS	12. PENSION PLANS The Company and its subsidiaries maintain defined contribution pension plans that cover a significant number of employees. In addition, the Company maintains defined benefit pension plans primarily in the U.K., France and Germany as well as a multiple-employer defined benefit pension plan in Switzerland. At September 30, 2018, the net pension liability was $83.6 (December 31, 2017—$111.1). The decrease in net pension liability was primarily due to a decrease in the U.K. pension liability due to an updated pension valuation. The U.K. pension valuation was updated for actual investment performance and certain changes in assumptions. The decrease in pension liability was primarily due to a decrease in the accrued benefit obligation resulting from an increase in the discount rate assumption since December 31, 2017. The discount rate was determined on a consistent basis and reflects prevailing rates available on high-quality, fixed income debt instruments. The Company’s net periodic benefit cost was as follows: Three Months Ended September 30 Nine Months Ended September 30 2018 2017 2018 2017 Defined contribution plans Contribution expense $ 3.0 $ 2.7 $ 9.7 $ 8.5 Defined benefit plans (1) Current service cost 0.3 0.6 1.1 1.7 Interest cost 2.0 2.2 6.3 6.4 Expected return on plan assets (2.4 ) (2.4 ) (7.6 ) (6.9 ) Recognized actuarial loss (2) 0.4 0.8 1.3 2.5 Total periodic benefit cost, net $ 3.3 $ 3.9 $ 10.8 $ 12.2 (1) Current service cost is recorded on the same line item as the relevant employee compensation cost on the consolidated statements of operations. Interest cost, expected return on plan assets and recognized actuarial loss are recorded in other income (expense) on the consolidated statements of operations. (2) Recognized actuarial loss represents the amortization of unrecognized actuarial loss out of accumulated other comprehensive loss into other income (expense).

COMMITMENTS, GUARANTEES AND CONTINGENCIES	13. COMMITMENTS, GUARANTEES AND CONTINGENCIES Intellectual Property Indemnification Obligations The Company enters, on a regular basis, into agreements with customers and suppliers that include limited intellectual property indemnification obligations that are customary in the industry. These guarantees generally require the Company to compensate the other party for certain damages and costs incurred as a result of third-party intellectual property claims arising from these transactions. The nature of these intellectual property indemnification obligations prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay to its customers and suppliers. Historically, the Company has not made any significant indemnification payments under such agreements and no amount has been accrued in the Interim Financial Statements with respect to these guarantees. Contingencies The Company is party to legal proceedings, claims and potential claims arising in the normal course of business. The Company’s management and legal counsel estimate that any monetary liability or financial impact of such claims or potential claims to which the Company might be subject after final adjudication would not be material to the Interim Financial Statements. In circumstances where the outcome of the lawsuit is expected to be unfavorable, the Company has recorded a provision for the expected settlement amount. Where the expected settlement amount is a range, the Company has provided for the best estimate within that range. If no amount within the range is more likely, the Company has provided for the minimum amount of the range. Letters of Credit and Guarantees Letters of credit, financial guarantees and other similar instruments are reviewed regularly, and the results of these reviews are considered in assessing the adequacy of the Company’s reserve for possible credit and guarantee losses. Letters of credit, bank guarantees and other similar instruments amounted to $5.3 as of September 30, 2018 (December 31, 2017 — $5.6). The estimated fair value of letters of credit, bank guarantees and similar instruments, which is equal to the fees paid to obtain the obligations, was not significant as of September 30, 2018 and December 31, 2017.

Although this purchase accounting requirement has no impact on the Company’s business or cash flow, it adversely impacts the Company’s revenue in the reporting periods following the acquisition. As a result, the Company’s chief operating decision maker reviews and evaluates this segment measure of revenue separately from the On-Site Geographic information The Company reports revenues by geographic location as follows: • Americas, consisting of the continents of North America and South America; • EMEA, consisting of the continent of Europe, including Russia, as well as the Middle East and Africa; and • Asia-Pacific, consisting of the continent of Asia and the Pacific region, including Australia and New Zealand.

Accounting pronouncements adopted in 2018	a) Accounting pronouncements adopted in 2018 Statement of cash flows – presentation of restricted cash In November 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-18 Income statement classification of net pension benefit costs In March 2017, the FASB issued ASU 2017-07 non-service Income taxes on intra-entity transfers of assets other than inventory In October 2016, the FASB issued ASU 2016-16 Revenue recognition In May 2014, the FASB issued ASU 2014-09 2015-14, 2016-08, 2016-10, 2016-11, 2016-12 2016-20, 2014-09. Revenues Previously, for non-essential non-essential non-essential non-essential Previously, for distribution agreements where the return rights were not limited and were outside the Company’s control, the Company deferred revenue until the product was sold to an end customer. Under the new revenue recognition standard, the Company recognizes revenue upon delivery to the distributor for products that are not expected to be returned. Contract costs Previously, the Company expensed as incurred certain costs incurred to obtain and fulfill a contract with a customer, including commissions paid to the Company’s internal salesforce and customer activation costs for customers under multi-year cloud contracts. Under the new revenue recognition standard, incremental costs incurred to obtain a contract, as well as costs to fulfill a contract must be deferred and amortized over the expected period that the related performance obligation is satisfied. The Company has elected to apply a practical expedient under the guidance and expenses costs to obtain a contract as incurred, if the amortization period would have been one year or less. For the Company’s On-Site For the Company’s recurring Cloud segment, a typical solution of hardware, software, and installation, training and support is provided to a customer under a monthly recurring billing model. Contract fulfillment costs such as installation costs and incremental costs to obtain the contract such as commissions paid to the internal salesforce are generally incurred at the outset of the contract. As a result, under the new revenue recognition standard, the Company now defers these costs over the term of the contract, plus any additional expected renewal periods. Summary of changes As a result of the above accounting policy changes relating to revenue recognition, at January 1, 2018 the Company recorded a decrease in inventory of $1.2, a decrease in current deferred revenue of $11.9, a decrease in the long-term portion of deferred revenue of $7.6 and an increase in shareholders’ equity of $18.3 on its consolidated balance sheet. The effect of the adoption on the Company’s results of operations for the three and nine months ended September 30, 2018 was not material. As a result of the above accounting policy changes relating to contract costs, at January 1, 2018 the Company recorded a contract asset of $19.0 and an increase in shareholders’ equity of $19.0. The effect of the adoption on the Company’s results of operations for the three and nine months ended September 30, 2018 was not material. In addition, there was a decrease to the Company’s net deferred tax asset of $9.2 and a corresponding decrease to shareholders’ equity of $9.2 to account for the tax effect of the above changes.

[1]	In accordance with the fair value provisions applicable to the accounting for business combinations, acquired deferred revenue relating to acquisitions is recorded on the opening balance sheet of the acquired company at an amount that is generally lower than the historical carrying value. Although this purchase accounting requirement has no impact on the Company's business or cash flow, it adversely impacts the Company's revenue in the reporting periods following the acquisition. As a result, the Company's chief operating decision maker reviews and evaluates this segment measure of revenue separately from the On-Site and Cloud segments.
