DISCONTINUED OPERATIONS	3. DISCONTINUED OPERATIONS On December 18, 2016, Mitel entered into a definitive agreement to divest its Mobile business unit to the parent company of Xura, Inc. (“Xura”) for $350.0 in cash, a $35.0 non-interest non-interest re-financing The disposal of the Mobile business unit is considered a strategic shift away from the sale of software-based network solutions for mobile carriers. As a result, the operations of the Mobile business unit have been reclassified as discontinued operations on the consolidated statements of operations and the assets and liabilities of the Mobile business unit have been reclassified as assets and liabilities held for sale on the consolidated balance sheets. Assets and liabilities held for sale for the Mobile business unit were as follows: December 31, Assets of component held for sale, current: Cash and cash equivalents $ 3.5 Accounts receivable 83.2 Inventories 7.1 Other current assets 27.5 $ 121.3 Assets of component held for sale, non-current: Property and equipment (net) $ 13.8 Identifiable intangible assets (net) 215.3 Goodwill 99.5 Other non-current 3.9 $ 332.5 Liabilities of component held for sale, current: Accounts payable and accrued liabilities $ 43.3 Current portion of deferred revenue 14.6 Current portion of long-term debt – capital leases 0.4 $ 58.3 Liabilities of component held for sale, non-current: Long-term debt – capital leases $ 0.9 Long-term portion of deferred revenue 1.7 Deferred tax liability 14.3 Other non-current 7.9 $ 24.8 Summarized results of operations for the Mobile business unit are as follows: Three Months Ended June 30 Six Months Ended June 30 2017 2016 2017 (1) 2016 Revenues $ — $ 46.9 $ 8.0 $ 90.0 Cost of revenues — (17.9 ) (6.3 ) (37.0 ) Selling, general and administrative expenses — (8.5 ) (5.5 ) (20.9 ) Research and development expenses — (14.1 ) (8.4 ) (25.7 ) Special charges and restructuring costs — (1.7 ) — (4.1 ) Amortization of acquisition-related intangible assets — (10.1 ) — (20.2 ) Interest expense (2) — (5.5 ) (3.7 ) (11.0 ) Gain on disposal — — 7.9 — Loss from discontinued operations, before income taxes — (10.9 ) (8.0 ) (28.9 ) Income tax recovery — 1.0 6.6 8.4 Comprehensive income (loss) $ — $ (9.9 ) $ (1.4 ) $ (20.5 ) (1) Operating results for the six months ended June 30, 2017 consist of the operations up to the date of close, February 28, 2017. (2) Interest expense allocated to discontinued operations consists of the pro-rata For the six months ended June 30, 2017 the loss from discontinued operations includes amortization and depreciation of nil and stock-based compensation of nil (three and six months ended June 30, 2016 — amortization and depreciation of $11.5 and $23.0, respectively and stock-based compensation of $0.7 and $1.5, respectively). The Mobile business unit incurred capital expenditures of $1.2 for the six months ended June 30, 2017 (three and six months ended June 30, 2016 — $0.5 and $0.7, respectively). Gain on disposal The Company recorded a gain on disposal of $7.9 in the first six months of 2017 consisting of the fair value of consideration received of $378.0, less the carrying value of net assets of $362.9 (which includes cash divested of $30.8), costs to sell incurred in the first quarter of 2017 of $2.6 and liabilities for representations, warranties and indemnifications of $4.6, as described below. The fair value of consideration received of $378.0 consisted of cash proceeds of $351.1 received on February 28, 2017, proceeds from the net working capital and other closing adjustments of $16.6, received in May 2017, and the fair value of the non-interest Representations, warranties and indemnifications The Company has provided the buyer with certain representations, warranties and indemnifications relating to the operations of the Mobile business unit, in particular relating to income and sales taxes.

For the three and six months ended June 30, 2017, the Company sold rental payments of $4.2 and $7.0, respectively, and recorded gains on sale of those rental payments of $0.6 and $0.9, respectively (three and six months ended June 30, 2016—sold $5.0 and $8.9, respectively and recorded gains of $0.7 and $1.4, respectively). Sold rental payments remaining unbilled at the end of the period represents the total balance of leases that are not included in the Company’s consolidated balance sheets. The Company is compensated for administration and servicing of rental payments sold. Financing receivables The Company considers its lease balances included in accounts receivable and its investment in sales-type leases to be financing receivables.

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: June 30, 2017 December 31, 2016 Individually evaluated for impairment Sales-type leases individually evaluated for impairment, gross $ 3.2 $ 3.2 Allowance against sales-type leases individually evaluated for impairment (1.4 ) (1.4 ) Sales-type leases individually evaluated for impairment, net $ 1.8 $ 1.8 Collectively evaluated for impairment Sales-type leases collectively evaluated for impairment, gross $ 49.5 $ 54.0 Allowance against sales-type leases collectively evaluated for impairment (1.1 ) (1.3 ) Sales-type leases collectively evaluated for impairment, net $ 48.4 $ 52.7

Our prior credit facilities (the “April 2015 Credit Facilities”) were repaid in March 2017 in conjunction with the new financing, as described below. March 2017 financing On March 9, 2017, Mitel refinanced its senior secured credit facilities. The new credit facilities were comprised of a $150.0 term loan and a $350.0 revolving facility (together, the “March 2017 Credit Facilities”). Proceeds of $150.0 from the term loan along with amounts initially drawn on the revolving facility of $95.0 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. Costs relating to the term loan were $2.0 and are recorded net against the term loan and are amortized over the term of the term loan. Costs of $4.6 relating to the revolving facility are recorded as other non-current The term loan and revolving credit facility bear interest at LIBOR plus an applicable margin or, at the option of the Company, a base rate plus an applicable margin, and mature in March 2022. The revolving credit facility also has an undrawn commitment fee. The applicable margin and the undrawn commitment fee on the revolving credit facility are based on the Consolidated Total Net Leverage Ratio (the “Leverage Ratio”), as defined in the credit facility (the ratio of Consolidated Total Indebtedness, net of up to $50.0 of unrestricted cash, to the trailing twelve months Consolidated EBITDA, as defined in the credit facility), and are as follows: Consolidated Total Net Leverage Ratio Commitment Fee Applicable Margin Less than 1.25 0.25 % 1.75 Greater than or equal to 1.25 but less than 1.75 0.25 % 2.00 Greater than or equal to 1.75 but less than 2.25 0.30 % 2.25 Greater than or equal to 2.25 but less than 2.75 0.35 % 2.50 Greater than or equal to 2.75 0.35 % 3.00 The Company is required to make principal repayments on the term loan of $1.9 per quarter from June 2017 to March 2018, $2.8 per quarter from June 2018 to March 2020 and $3.8 per quarter from June 2020 to December 2021. The term loan can be repaid without premium or penalty. The March 2017 Credit Facilities have customary default clauses, such that repayment of the credit facilities may be accelerated in the event of an uncured default. The proceeds from the issuance of debt, and proceeds from the sale of Company assets, may also be required to be used, in whole or in part, to make mandatory prepayments under the March 2017 Credit Facilities. The March 2017 Credit Facilities 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 June 30, 2017. The maximum Leverage Ratio is as follows: Fiscal Quarters Ending Maximum Consolidated March 31, 2017 through June 30, 2018 3.50 July 1, 2018 and thereafter 3.25 The maximum Leverage Ratio is increased to 3.75 for the four fiscal quarters following a Material Acquisition, as defined in the credit facility. 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 The minimum Interest Coverage Ratio throughout the term of the credit facility is 3.00. The Interest Coverage Ratio at June 30, 2017 was 5.87. Other 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 3. In addition, in January 2017 the Company made prepayments of $22.6 on its term loan. In the first quarter of 2017, the Company expensed $18.0 of unamortized debt issue costs and unamortized original issue discount relating to the prepayments and the full repayment of the prior credit facilities, as described above. In 2016, Mitel made prepayments on its term loan of $25.0 in January, $15.0 in March, $13.6 in June and $11.5 in July and recorded debt retirement costs of $1.3, $0.4 and $0.4 in the first, second and third quarter of 2016, respectively, for the write-off pro-rata

COMMITMENTS, GUARANTEES AND CONTINGENCIES	11. 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, then 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 $8.3 at June 30, 2017 (December 31, 2016 — $6.2). 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 at June 30, 2017 and December 31, 2016.
