BASIS OF PRESENTATION

BASIS OF PRESENTATION	3 Months Ended
	Mar. 31, 2016
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION These unaudited interim consolidated financial statements (“Interim Financial Statements”) have been prepared by Mitel Networks Corporation (“Mitel” or the “Company”) in United States (“U.S.”) dollars and, unless otherwise stated, in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial statements. Accordingly, the Interim Financial Statements do not include all information and footnotes normally included in annual financial statements prepared in accordance with GAAP and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for annual financial statements. In the opinion of management, the Interim Financial Statements reflect all adjustments of a normal recurring nature that are necessary for a fair presentation of the results for the interim periods presented. These Interim Financial Statements and the accompanying notes should be read in conjunction with the annual financial statements and notes thereto for each of the years ended December 31, 2015 and December 31, 2014, eight months ended December 31, 2013 and year ended April 30, 2013 (the “Annual Financial Statements”) contained in the Company’s report on Form 10-K filed with the SEC on February 29, 2016. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full year or future periods.

SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES	2. SIGNIFICANT ACCOUNTING POLICIES The Company’s significant accounting policies at December 31, 2015 are described in note 2 to the Annual Financial Statements. Recently issued accounting pronouncements Other than the accounting pronouncements below, there have been no recent accounting pronouncements that are expected to have a significant effect on the consolidated financial statements. Revenue recognition In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09 “Revenue from Contracts with Customers” to provide a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The ASU supersedes most current revenue recognition guidance, including industry-specific guidance. In March 2016, the FASB issued ASU 2016-08, to clarify certain guidance in ASU 2014-09. In August 2015, the FASB issued ASU 2015-14 to amend the effective date of ASU 2014-09. As a result, ASU 2014-09 becomes effective for the Company in the first quarter of 2018, with early adoption permitted no earlier than the first quarter of 2017. The Company is currently evaluating the effect the adoption of these ASUs will have on its consolidated financial statements, which could impact the timing and amounts of revenue recognized. Leases In February 2016, the FASB issued ASU 2016-02 “Leases” to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. For operating leases, the ASU requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The ASU also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. The ASU is effective for the Company for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the effect the adoption of this ASU will have on its consolidated financial statements. Stock-based compensation In March 2016, the FASB issued ASU 2016-09 “Compensation – Stock Compensation” to simplify and improve accounting for stock-based compensation. The ASU, among other changes, allows for a policy election such that an entity can continue to estimate forfeitures at the time of grant or can account for forfeitures as they occur. The amendment becomes effective for the Company in the first quarter of 2017. Early adoption is permitted. The Company is currently evaluating the effect the adoption of this ASU will have on its consolidated financial statements.

ACQUISITIONS	3. ACQUISITIONS a) Mavenir – April 2015 On April 29, 2015, Mitel acquired Mavenir Systems, Inc. (“Mavenir”) (NYSE:MVNR), a global provider of software-based networking solutions for mobile carriers. Mitel acquired all of the outstanding common shares of Mavenir in exchange for $325.2 cash and 19.7 million Mitel shares. In addition, Mitel agreed to cash out all in-the-money, vested Mavenir stock options and, in exchange for all out-of-the-money and unvested Mavenir stock options, issue 2.5 million Mitel stock options with economically similar terms. In conjunction with the acquisition, the Company completed a refinancing of its long-term senior debt, as described in note 10. Mavenir’s results of operations are included in the results of operations of the combined entity from the date of acquisition. The following unaudited pro-forma financial information presents the Company’s consolidated financial results as if the acquisition had occurred at the beginning of the period: Three Months Ended Operations Revenues $ 274.2 Net loss $ (28.1 ) Net loss per share $ (0.23 ) These pro-forma results have been prepared for comparative purposes only and are not necessarily indicative of the results of operations that actually would have resulted had the acquisition been effected at the beginning of the period and are not necessarily representative of future results. The pro-forma results include the following adjustments: • Amortization of intangible assets that arose from the acquisition of $31.6 per year; • A reduction to revenue for the three months ended March 31, 2015 of $2.2 as a result of the valuation of the deferred revenue acquired being below Mavenir’s historical book value and the corresponding decrease in revenues in subsequent periods; and • A tax provision based on an estimated effective tax rate of nil as a result of previously unrecognized tax loss carryforwards. Additional details of the acquisition, including the allocation of the purchase price to the net assets acquired, are included in note 3 to the Annual Financial Statements. b) Tiger TMS – June 2015 On June 1, 2015, Mitel acquired all of the outstanding equity of Tiger TMS (“Tiger”), a global provider of software, cloud and applications-based solutions for the hospitality industry. Tiger recorded revenues of approximately $10.0 for the year ended December 31, 2014, which were primarily generated in Europe, the Middle East and the United States. Total consideration for the acquisition was estimated to be $8.6. Tiger’s results of operations are included in the results of operations of the combined entity from the date of acquisition. Additional details of the acquisition, including the allocation of the purchase price to the net assets acquired, are included in note 3 to the Annual Financial Statements.

NET INVESTMENT IN SALES-TYPE LEASES	3 Months Ended
	Mar. 31, 2016
NET INVESTMENT IN SALES-TYPE LEASES	4. NET INVESTMENT IN SALES-TYPE LEASES Net investment in sales-type leases represents the value of sales-type leases held in the U.S. and Europe. The Company currently sells the rental payments due to the Company from some of the sales-type leases in the U.S. The Company maintains reserves against its estimate of potential recourse for the balance of sales-type leases (recorded net, against the receivable) and for the balance of sold rental payments remaining unbilled (recorded separately as a lease recourse liability included in other non-current liabilities). The following table provides detail on the sales-type leases: March 31, 2016 December 31, 2015 Gross Allowance Net Gross Allowance Net Lease balances included in accounts receivable $ 4.6 $ (0.9 ) $ 3.7 $ 5.6 $ (0.9 ) $ 4.7 Current portion of investment in sales-type leases 11.2 (0.3 ) 10.9 13.0 (0.4 ) 12.6 Non-current portion of investment in sales-type leases 18.0 (0.6 ) 17.4 17.5 (0.5 ) 17.0 Total unsold sales-type leases (recorded as assets, net, on the consolidated balance sheets) 33.8 (1.8 ) 32.0 36.1 (1.8 ) 34.3 Sold rental payments remaining unbilled 44.8 (1.7 ) (1) 43.1 47.6 (1.9 ) (1) 45.7 Total of sales-type leases unsold and sold $ 78.6 $ (3.5 ) $ 75.1 $ 83.7 $ (3.7 ) $ 80.0 (1) Allowance for sold rental payments is recorded as a lease recourse liability and included in other non-current liabilities on the consolidated balance sheets. A sale of rental payments represents the total present value of the payment stream on the sale of the rental payments to third parties. For the three months ended March 31, 2016, the Company sold $3.9 of rental payments and recorded gains on sale of those rental payments of $0.7 (three months ended March 31, 2015—sold $3.3 and recorded gains of $0.5). 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. Additional disclosures on the credit quality of the Company’s sold and unsold sales-type leases and lease balances included in accounts receivable are as follows: Aging Analysis as of March 31, 2016 Not past due 1-90 days Greater than Total past due Total sales-type leases Lease balances included in accounts receivable $ 2.4 $ 1.3 $ 0.9 $ 2.2 $ 4.6 Investment in sold and unsold sales-type lease receivables 67.2 6.5 0.3 6.8 74.0 Total gross sales-type leases 69.6 7.8 1.2 9.0 78.6 Allowance (1.5 ) (1.0 ) (1.0 ) (2.0 ) (3.5 ) Total net sales-type leases $ 68.1 $ 6.8 $ 0.2 $ 7.0 $ 75.1 Aging Analysis as of December 31, 2015 Not past due 1-90 days Greater than Total past Total sales-type leases Lease balances included in accounts receivable $ 3.1 $ 1.6 $ 0.9 $ 2.5 $ 5.6 Investment in sold and unsold sales-type lease receivables 67.6 10.2 0.3 10.5 78.1 Total gross sales-type leases 70.7 11.8 1.2 13.0 83.7 Allowance (1.5 ) (1.1 ) (1.1 ) (2.2 ) (3.7 ) Total net sales-type leases $ 69.2 $ 10.7 $ 0.1 $ 10.8 $ 80.0 Allowance for credit losses The Company’s allowance for credit losses is based on management’s assessment of the collectability of customer accounts. 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 following table shows the activity of the allowance for credit losses on sales-type leases: Three Months Year Ended Allowance for credit losses on sales-type leases, opening $ (3.7 ) $ (4.3 ) Write-offs 0.2 0.6 Recoveries — — Provision — — Allowance for credit losses on sales-type leases, closing $ (3.5 ) $ (3.7 ) The amount of gross sales-type leases individually and collectively evaluated for impairment is as follows: March 31, 2016 December 31, 2015 Individually evaluated for impairment Sales-type leases individually evaluated for impairment, gross $ 3.9 $ 4.2 Allowance against sales-type leases individually evaluated for impairment (1.7 ) (1.9 ) Sales-type leases individually evaluated for impairment, net $ 2.2 $ 2.3 March 31, 2016 December 31, 2015 Collectively evaluated for impairment Sales-type leases collectively evaluated for impairment, gross $ 74.7 $ 79.5 Allowance against sales-type leases collectively evaluated for impairment (1.8 ) (1.8 ) Sales-type leases collectively evaluated for impairment, net $ 72.9 $ 77.7

Voluntary prepayments can be applied against mandatory principal repayments under the credit facility. As a result, at March 31, 2016, no amount of the term loan has been recorded as current (December 31, 2015 – $6.6). In February 2015, Mitel made a voluntary prepayment of $25.0 on its term loan. As a result, the Company recorded debt retirement costs of $0.7 in the first quarter of 2015 for the write-off of the pro-rata portion of unamortized debt issue costs and original issue discount. April 2015 refinancing On April 29, 2015, in conjunction with the acquisition of Mavenir, as described in note 3, Mitel refinanced its senior secured credit facilities. The new credit facilities initially consisted of a $660.0 term loan and a $50.0 revolving facility (the “April 2015 Credit Facilities”). Proceeds of $653.4 (net of original discount of $6.6), along with cash on hand, were used to repay the remaining $279.1 principal outstanding under the prior credit facilities, to repay the remaining $26.9 principal outstanding under Mavenir’s credit facilities, for the cash consideration paid for the acquisition of Mavenir (as described in note 3), as well as accrued interest, fees and expenses in connection with the refinancing and the acquisition of Mavenir. Costs relating to the term loan were $15.5, in addition to an original issue discount of $6.6. Costs relating to the term loan and original issue discount are recorded net against the term loan and are amortized over the term of the term loan. Costs of $1.7 relating to the revolving facility are recorded as other non-current assets and are amortized on a straight-line basis over the term of the revolving facility. In addition, the Company expensed $8.4 of unamortized debt issue costs and unamortized original issue discount relating to the repayment of the prior credit facilities. Additional details on the April 2015 Credit Facilities are included in note 13 to the Annual Financial Statements.

PENSION PLANS

PENSION PLANS	11. 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 March 31, 2016, the net pension liability was $140.9 (December 31, 2015—$126.6). The increase in liability from December 31, 2015 was primarily due to an increase in the U.K. and Switzerland pension plan liabilities due to updated pension valuations. At March 31, 2016, the U.K. and Switzerland pension plan valuations from December 31, 2015 were updated for actual investment performance and certain changes in assumptions. The increases in the pension liabilities were primarily due to increases in the accrued benefits obligations resulting from decreases in the discount rates since December 31, 2015. The discount rates were determined on a consistent basis and reflect prevailing rates available on high-quality, fixed income debt instruments. The Company’s net periodic benefit cost was as follows: Three Months Ended March 31, March 31, Defined contribution plans Contribution expense $ 4.3 $ 3.2 Defined benefit plans Current service cost 0.7 0.8 Interest cost 2.6 2.9 Expected return on plan assets (2.7 ) (2.7 ) Recognized actuarial loss (1) 0.6 0.5 Total periodic benefit cost, net $ 5.5 $ 4.7 (1) Recognized actuarial loss represents the amortization of unrecognized actuarial loss out of accumulated other comprehensive loss into operating expenses, primarily selling, general and administrative expense.

COMMITMENTS, GUARANTEES AND CONTINGENCIES	12. 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 $9.0 as of March 31, 2016 (December 31, 2015 — $10.0). 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 March 31, 2016 and December 31, 2015.

The segments are further described in note 22 to the Annual Financial Statements. Up to December 31, 2015, the primary financial measures of performance of the segments consisted of revenues and gross margin. Beginning in the first quarter of 2016, the primary financial measures of performance used by the chief operating decision maker were expanded to include segment income, which is gross margin less selling, general and administrative expenses, research and development expenses and other expense (income), excluding foreign exchange loss (gain). The expenses are generally directly charged to the segment. In certain cases expenses are allocated to the segment on a pro-rata basis using an appropriate allocation method. The following table presents the results of operations for the Company’s segments: Three Months Ended March 31, 2016 Enterprise Cloud Mobile Total (1) Revenues Product $ 119.0 $ 16.0 $ 29.3 $ 164.3 Recurring 47.0 29.5 9.4 85.9 Services 21.2 0.3 5.1 26.6 187.2 45.8 43.8 276.8 Purchase accounting adjustments (2) — — (0.7 ) (0.7 ) Total revenues 187.2 45.8 43.1 276.1 Gross margin Product 66.7 10.0 16.6 93.3 Recurring 26.8 14.5 5.5 46.8 Services 5.7 0.1 2.6 8.4 99.2 24.6 24.7 148.5 Purchase accounting adjustments (2) — — (0.7 ) (0.7 ) Total gross margin 99.2 24.6 24.0 147.8 Selling, General and Administrative 68.1 15.1 14.0 97.2 Research and Development 18.6 6.6 11.6 36.8 Other expense (income) (3) (0.2 ) (0.1 ) — (0.3 ) Segment income (loss) $ 12.7 3.0 (1.6 ) 14.1 Other information Depreciation and amortization $ 3.9 $ 0.8 $ 1.8 $ 6.5 Stock-based compensation $ 3.0 $ 0.5 $ 0.8 $ 4.3 (1) Total amounts for revenues, gross margin, selling, general and administrative expenses, and research and development expenses are as reported on the consolidated statement of operations.

(“Polycom”) (NYSE:PLCM) entered into a definitive merger agreement under which Mitel agreed to acquire all of the outstanding shares of Polycom common stock in a cash and stock transaction. Under the terms of the agreement, Polycom stockholders will be entitled to $3.12 in cash and 1.31 Mitel common shares for each share of Polycom common stock.

Polycom is a global provider of unified video, voice and content communications solutions with annual revenues of $1,267.2 for the year ended December 31, 2015. Mitel intends to use a combination of cash on hand from the combined business and proceeds from new financing to finance the cash portion of the consideration for the acquisition, the refinancing of its existing credit facilities and those of Polycom, and accrued interest, fees and expenses in connection with the acquisition and the refinancing.

Recently issued accounting pronouncements	Recently issued accounting pronouncements Other than the accounting pronouncements below, there have been no recent accounting pronouncements that are expected to have a significant effect on the consolidated financial statements. Revenue recognition In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09 “Revenue from Contracts with Customers” to provide a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The ASU supersedes most current revenue recognition guidance, including industry-specific guidance. In March 2016, the FASB issued ASU 2016-08, to clarify certain guidance in ASU 2014-09. In August 2015, the FASB issued ASU 2015-14 to amend the effective date of ASU 2014-09. As a result, ASU 2014-09 becomes effective for the Company in the first quarter of 2018, with early adoption permitted no earlier than the first quarter of 2017. The Company is currently evaluating the effect the adoption of these ASUs will have on its consolidated financial statements, which could impact the timing and amounts of revenue recognized. Leases In February 2016, the FASB issued ASU 2016-02 “Leases” to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. For operating leases, the ASU requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The ASU also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. The ASU is effective for the Company for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the effect the adoption of this ASU will have on its consolidated financial statements. Stock-based compensation In March 2016, the FASB issued ASU 2016-09 “Compensation – Stock Compensation” to simplify and improve accounting for stock-based compensation. The ASU, among other changes, allows for a policy election such that an entity can continue to estimate forfeitures at the time of grant or can account for forfeitures as they occur. The amendment becomes effective for the Company in the first quarter of 2017. Early adoption is permitted. The Company is currently evaluating the effect the adoption of this ASU will have on its consolidated financial statements.
