	1. BASIS OF PRESENTATION
	These unaudited interim consolidated financial statements have been prepared by Mitel Networks Corporation (“Mitel” or the “Company”) in United States (“U.S.”) dollars, unless otherwise stated, and in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial statements. Accordingly, these unaudited interim consolidated financial statements do not include all information and footnotes normally included in financial statements prepared in accordance with GAAP and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for complete financial statements. In the opinion of management of the Company, these unaudited interim consolidated financial statements reflect all adjustments necessary to present fairly the financial position at March 31, 2014 and the results of operations and cash flows of the Company for each of the three-month periods ended March 31, 2014 and March 31, 2013 in accordance with GAAP applied on a consistent basis.
	These unaudited interim consolidated financial statements and the accompanying notes should be read in conjunction with the audited annual consolidated financial statements and notes thereto for the eight months ended December 31, 2013 and each of the three years ended April 30, 2013, 2012 and 2011 contained in the Company’s Transition Report on Form 10-K filed with the SEC on March 31, 2014 (the “audited annual consolidated financial statements”). 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	'
	2. SIGNIFICANT ACCOUNTING POLICIES
	The Company’s significant accounting policies at December 31, 2013 are described in note 2 to the audited annual consolidated financial statements. In addition to these policies, the Company has adopted a significant accounting policy relating to a multi-employer pension plan as a result of the acquisition of Aastra Technologies Ltd. (“Aastra”), as described in note 3. Also, in connection with the acquisition of Aastra, the Company changed its operating segments, as described in note 18.
	Reclassification
	In conjunction with the acquisition of Aastra, we reclassified service inventory from other current assets to inventory on the consolidated balance sheets. To conform to the current years’ presentation, $2.9 of service inventory, consisting of gross service inventory of $5.1 and a provision against service inventory of $2.2, was reclassified from other current assets to inventory at December 31, 2013.
	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.
	Classification of unrecognized tax benefits
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-11 to include explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss carryforward or a tax credit carryforward exists. The ASU provides amendments to the Income Taxes subtopic of the FASB Accounting Standards Codification (“ASC”), such that generally, unrecognized tax benefits should be presented as a reduction of deferred tax assets created by net operating losses or tax credit carryforwards in the same jurisdiction. The Company adopted this ASU prospectively in the first quarter of 2014. The adoption did not have a material impact on the consolidated financial statements.
	Discontinued operations
	In April 2014, the FASB issued ASU 2014-08 to change the criteria for reporting discontinued operations such that disposals of small groups of assets will no longer qualify for discontinued operations presentation. The ASU provides amendments to the Presentation of Financial Statements and Property, Plant and Equipment subtopics of the FASB ASC. As a result of the ASU, only those disposals of components that represent a strategic shift that has or will have a major effect on the entity’s operations will be reported as discontinued operations. The Company will adopt this ASU prospectively, no later than the first quarter of 2015.

	3. ACQUISITIONS
	a) Aastra – January 2014
	On November 10, 2013, Mitel and Aastra entered into a definitive arrangement agreement under which Mitel agreed to acquire all of the outstanding Aastra common shares in exchange for cash consideration of $80.0 as well as the issuance of approximately 44.2 million Mitel common shares. Aastra was a global provider of unified communications and collaboration software, solutions and services with annual revenues of approximately $600.0 Canadian dollars for the year ended December 31, 2013, of which approximately 75% were generated in Europe. The transaction was completed on January 31, 2014. In conjunction with the acquisition the Company completed a refinancing of its long-term senior debt, as described in note 11.
	Under the terms of the agreement, on January 31, 2014, Mitel increased the number of directors on its board of directors from eight to nine, and two members of Mitel’s then-existing board of directors resigned. Mitel’s board of directors appointed three new board members, as selected by the former board of directors of Aastra, to fill the vacancies.
	The total value of consideration given by Mitel was $471.3, consisting of $80.0 of cash and 44.2 million Mitel common shares valued at $391.3 on January 31, 2014. Mitel management believes the transaction provides the Company with the financial scale and operating leverage to capitalize on the global growth opportunity as the market begins a long-term migration to the cloud. The transaction will allow the combined company to leverage the research and development workforce acquired as well as realize synergies, primarily through general and administrative and procurement savings. These factors contributed to the recognition of goodwill for the acquisition.
	The Company is required to allocate the purchase price to tangible and identifiable intangible assets acquired and liabilities assumed based on their fair values. The excess of the purchase price over those fair values is recorded as goodwill. As the transaction was completed recently, the accounting for the acquisition, including estimating the fair values of assets and liabilities acquired, is still being completed. As a result, the final purchase price allocation may differ significantly from the estimates. The estimated purchase price and allocation of the purchase price is as follows:
			January 31, 2014
	Net assets:
	Cash and cash equivalents		$	79.4
	Accounts receivable(1)			111.5
	Sales-type lease receivables, current			10.1
	Inventories(2)			62.6
	Deferred tax asset, current			7.8
	Other current assets			32
	Sales-type lease receivables, non-current			13.3
	Deferred tax asset, non-current			5.3
	Property and equipment			23.9
	Intangible assets – customer relationships(3)(7)			13
	Intangible assets – developed technology(4)(7)			152.6
	Intangible assets – trade name(5)(7)			9
	Goodwill(6)(7)			177.8
	Other non-current assets			0.5
	Accounts payable and accrued liabilities(8)			(118.9	)
	Deferred revenue, current			(24.9	)
	Current portion of long-term debt			(1.8	)
	Deferred revenue, non-current			(12.5	)
	Pension liability(9)			(26.4	)
	Deferred tax liability			(30.6	)
	Other non-current liabilities			(12.4	)
	Net assets acquired		$	471.3
	Consideration given:
	Amount paid, cash		$	80
	Value of Mitel common shares issued			391.3
	Total consideration given		$	471.3
	-1	Fair value of accounts receivable consists of gross contractual amounts receivable of $118.7, less best estimate of amounts not expected to be collected of $7.2.
	-2	Fair value of inventory determined based on gross inventory of $89.7 less a historical provision of $27.1.
	-3	Intangible assets – customer relationships are expected to be amortized over the estimated useful life of the asset of 7 years.
	-4	Intangible assets – developed technology is expected to be amortized over the estimated useful life of the asset of 6 years.
	-5	Intangible assets – trade name is expected to be amortized over the estimated useful life of the asset of 4 years.
	-6	Goodwill will be allocated to the new reporting segments on a relative fair value basis once the purchase price allocation is finalized.
	-7	Neither the goodwill nor the intangible assets are expected to be deductible for tax purposes.
	-8	Included in accounts payable and accrued liabilities is $3.7 relating to accrued contingent consideration recorded for the acquisition of Telepo Ltd. by Aastra on January 20, 2014.
	-9	The amounts recorded for pension liability consist primarily of unfunded defined benefit pension plans in France and Germany. Excluded from the pension liability is a multi-employer defined benefit plan in Switzerland. As a result of the assets in the plan being pooled as well risk-sharing of the liabilities in the plan, the plan is considered a multi-employer defined benefit plan under U.S. GAAP and, as such, contributions are expensed as paid and no amount has been recorded as a pension liability as withdrawal from the plan was not considered probable at January 31, 2014 and March 31, 2014. At January 31, 2014 Aastra’s share of the plan’s assets and projected benefit obligation was $98.4 and $104.1, respectively.
	Aastra’s results of operations are included in the income statement of the combined entity from the date of acquisition. The amount of revenue and net loss included in the Company’s results of operations from January 31, 2014 to March 31, 2014 from the acquisition was $89.3 and $1.5, respectively. The revenue and net loss include a reduction of $2.8 as a result of the valuation of the deferred revenue liabilities acquired being below Aastra’s historical book value and the corresponding decrease in revenues in subsequent periods. The net loss also includes amortization of acquired intangible assets of $4.9.
	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
			March 31,			March 31,
			2014			2013
	Operations
	Revenues		$	277.4		$	273.5
	Net loss			(30.8	)		(8.8	)
	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 respective periods 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 $29.5 per year
		•		A reduction to revenue for the three months ended March 31, 2014 (relating to the pro-forma period from January 1, 2014 to January 31, 2014) and three months ended March 31, 2013 of $1.1 and $3.9, respectively, as a result of the valuation of the deferred revenue acquired being below Aastra’s historical book value and the corresponding decrease in revenues in subsequent periods.
		•		Tax provision based on an estimated effective tax rate of approximately 20%
	b) Oaisys – March 2014
	On March 4, 2014, Mitel completed the acquisition of Oaisys, a leading developer of integrated call recording and quality management solutions. The acquisition of Oaisys further strengthens Mitel’s position in the growing contact center market. Mitel paid $5.9 for all of the outstanding equity of Oaisys. In addition, up to $3.0 may be paid upon Oaisys meeting certain revenue targets for the year ended April 30, 2014. The Company estimates the fair value of the contingent consideration to be $2.0, based on the estimated Oaisys results for the year ended April 30, 2014. As the transaction was completed recently, the accounting for the acquisition, including estimating the fair values of assets and liabilities acquired, is still being completed. The estimated purchase price and allocation of the purchase price is as follows:
			March 4, 2014
	Net assets:
	Cash and cash equivalents		$	0.3
	Accounts receivable			1.8
	Inventories			0.1
	Deferred tax asset, current			0.4
Other current assets			0.2
Deferred tax asset, non-current			0.1
Property and equipment			0.1
Intangible assets – developed technology(1)(2)			4
Goodwill(2)			3.4
Other non-current assets			0.6
Accounts payable and accrued liabilities			(1.1	)
Deferred revenue, current			(1.3	)
Deferred revenue, non-current			(0.7	)
Net assets acquired		$	7.9
Consideration given:
Cash paid, March 2014		$	5.9
Fair value estimate of contingent consideration			2
Total consideration given		$	7.9
-1	Intangible assets – developed technology is expected to be amortized over the estimated useful life of the asset of 4 years.
-2	Neither the goodwill nor the intangible assets are expected to be deductible for tax purposes.
Oaisys’ results of operations are included in the income statement of the combined entity from the date of acquisition, March 4, 2014. Oaisys’ annual revenues were approximately $8.1 for the year ended December 31, 2013.
c) prairieFyre – June 2013
On June 17, 2013, the Company completed the acquisition of prairieFyre Software Inc. (“prairieFyre”), a global provider of contact center, business analytics, and workforce optimization software and services. The acquisition provides Mitel with a cornerstone development platform to address increasing demand for cloud-based contact center solutions. The net cash cost to Mitel for the acquisition was $20.0 for a 100% equity ownership interest in prairieFyre. The net cash cost consisted of cash paid of $27.3 less cash and cash equivalents acquired of $4.2 and acquired accounts receivable due from Mitel of $3.1. Additional details, including the allocation of the purchase price to the net assets acquired is included in note 3 to the audited annual consolidated financial statements.

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). The following table provides detail on the sales-type leases:
			March 31, 2014									December 31, 2013

	-1	Allowance for sold rental payments is recorded as a lease recourse liability 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, 2014, the Company sold $4.7 of rental payments and recorded gains on sale of those rental payments of $0.8 (three months ended March 31, 2013—sold $5.9 and recorded gains of $0.9). 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 consolidated 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:

	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:

	Dr. Terence Matthews (“Dr. Matthews”) and certain entities controlled by Dr. Matthews (collectively, the “Matthews Group”) are significant common shareholders of the Company. Significant transactions with the Matthews Group include the following:
	Leased properties
	The Company leases its Ottawa-based headquarter facilities from the Matthews Group. During the three months ended March 31, 2014, Mitel recorded lease expense for base rent and operating costs of $1.4 (three months ended March 31, 2013—$1.1).
	Investment
	The Company has paid $1.0 for an option to invest in a company in India, over which company the Matthews Group has significant influence. For the three months ended March 31, 2014, sales to and purchases from this venture, arising in the normal course of the Company’s business, were $0.1 and $0.1, respectively, (three months ended March 31, 2013— $0.1 and $0.2, respectively).

LONG-TERM DEBT	'
	11. LONG-TERM DEBT
	On January 31, 2014, in conjunction with the acquisition of Aastra, Mitel refinanced its credit facilities. The new credit facilities consist of a $355.0 term loan and a $50.0 revolving facility (the “January 2014 Credit Facilities”). Proceeds of $353.2 (net of original discount of $1.8), along with cash on hand, were used to repay the remaining $258.5 outstanding on the prior credit facilities, the $80.0 of cash consideration paid for the acquisition of Aastra, as well as fees and expenses in connection with the refinancing and the acquisition of Aastra.
	Total fees and expenses related to the January 2014 Credit Facilities of $11.0 will be deferred and amortized over the term of the credit facilities using the effective interest method when related to the term loan and the straight-line method when related to the revolving facility. Original issue discount of $1.8 will be recorded net against the term loan and will be amortized over the term of the credit facilities using the effective interest method. In addition, the Company expensed $10.0 of unamortized debt issue costs and unamortized original issue discount, $4.2 of prepayment fees relating to the prior credit facilities and $0.5 of other costs relating to the refinancing.
	The undrawn $50.0 revolving credit facility bears interest at LIBOR plus 4.25%, or, at the option of the Company, a base rate plus an applicable margin, and matures in January 2019. The Company may borrow Canadian dollars under the revolving credit facility. Such borrowings bear interest at the Canadian prime rate plus an applicable margin. The $355.0 term loan bears interest at LIBOR (subject to a 1.00% floor) plus 4.25%, or, at the option of the Company, a base rate plus an applicable margin, and matures in January 2020. The term loan requires quarterly principal repayments of 0.25% of the original outstanding principal.
	The Company is also required to make annual principal repayments on the term loan based on a percentage of excess cash flow (as defined in the January 2014 Credit Facilities). The annual excess cash flow repayments are required to be paid within 100 days of the end of the fiscal year. The first annual excess cash flow payment is required be paid within 100 days of December 31, 2014.
	The Company may prepay the term loan at a premium of 1% over the principal amount within the first six months using proceeds from a refinancing. Otherwise, the term loan can be repaid without premium or penalty. The January 2014 Credit Facilities have customary default clauses, wherein 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 credit facilities.
	The January 2014 Credit Facilities contained affirmative and negative covenants, including: (a) periodic financial reporting requirements, (b) a maximum ratio of Consolidated Total Debt (net of up to $50.0 of unrestricted cash) to the trailing twelve months Earnings before Interest, Taxes, Depreciation and Amortization (“Leverage Ratio”), as specified in the credit facilities, (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. The maximum Leverage Ratio applies to the Company for the period ending June 30, 2014 and for all fiscal quarters thereafter until maturity in January 2020, and is as follows:
	Fiscal Quarters Ending	Maximum Consolidated
		Leverage Ratio
	June 30, 2014 through March 31, 2015		3.00:1.00

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 in the U.K., France and Germany as well as a multi-employer defined benefit pension plan in Switzerland. At March 31, 2014, the pension liability was $91.3 (December 31, 2013—$57.3). The increase in liability was primarily due to the additions of the France and Germany plans ($7.8 and $16.9 at March 31, 2014, respectively) as a result of the Aastra acquisition, as described in note 3, as well as an increase in the U.K. pension plan due to an updated pension valuation. At March 31, 2014, the U.K. pension valuation from December 31, 2013 was updated for actual investment performance and certain changes in assumptions. The increase in the U.K. pension liability was primarily due to an increase in the accrued benefits obligation resulting from a decrease in the discount rate from 4.7% at December 31, 2013 to 4.6% at March 31, 2014, as well as a lower return on assets when compared to the expected return. The discount rate assumption 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:

COMMITMENTS, GUARANTEES AND CONTINGENCIES	'
	13. COMMITMENTS, GUARANTEES AND CONTINGENCIES
	Intellectual Property Indemnification Obligations
	The Company enters into agreements on a regular basis 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 unaudited interim consolidated financial statements with respect to these guarantees.
	Contingencies
	The Company is party to a small number of legal proceedings, claims or potential claims arising in the normal course of business. In the opinion of the Company’s management and legal counsel, 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 consolidated financial position of the Company, its results of operations or its cash flows. 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.
	Bid and Performance Related Bonds
	The Company enters into bid and performance related bonds related to various customer contracts. Performance related bonds usually have a term of twelve months and bid bonds generally have a much shorter term. Potential payments due under these bonds may be related to the Company’s performance and/or the Company’s resellers’ performance under the applicable contract. The Company must measure and recognize a liability equal to the fair value of bid and performance related bonds involving the performance of the Company’s resellers. At March 31, 2014 and December 31, 2013, the liability recognized in accounts payable and accrued liabilities related to these bid and performance related bonds, based on past experience and management’s best estimate, was not significant. At March 31, 2014, the total maximum potential amount of future payments the Company could be required to make under bid and performance related bonds was $7.3 (December 31, 2013—$0.3).
	Letters of Credit and Guarantees
	Requests for providing commitments to extend credit and financial guarantees are reviewed and approved by management. Management regularly reviews all outstanding commitments, letters of credit and financial guarantees, 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 amounted to $1.7 as of March 31, 2014 (December 31, 2013—$1.2). In addition, the Company has provided bank guarantees totaling of $6.3 at March 31, 2014 (December 31, 2013— nil), primarily relating to lease facilities and benefit obligations. The estimated fair value of letters of credit and guarantees, which is equal to the fees paid to obtain the obligations, was not significant as of March 31, 2014 and December 31, 2013.

	In April 2014, the Company granted 0.7 million options and 0.3 million restricted stock units. The options were issued at an exercise price of $10.11 per option and vest quarterly over four years. The restricted stock units vest one-quarter on each of March 1, 2015, March 1, 2016, March 1, 2017 and December 15, 2017. Generally, a restricted stock unit, once vested, entitles the holder to a Mitel common share issued out of treasury.

	Special charges and restructuring costs of $13.2 were recorded in the three months ended March 31, 2014, primarily relating to the acquisition and integration of Aastra. The costs consisted of $2.2 of employee-related charges, $1.1 of facility-related charges, $4.9 of integration-related charges as well as $5.0 of acquisition-related charges. The employee-related charges consisted of headcount reductions of approximately 50 people and related costs, primarily in North America.

SEGMENT_INFORMATION

SEGMENT INFORMATION	3 Months Ended

SEGMENT INFORMATION	'
	18. SEGMENT INFORMATION
	The Company’s Chief Executive Officer (“CEO”) has been identified as the chief operating decision maker. The CEO evaluates the performance of the segments and allocates resources based on information provided by the Company’s internal management system.
	During the first quarter of 2014, in connection with the acquisition of Aastra, the Company reorganized its business. As a result, the CEO now evaluates performance and allocates resources based on two key business units, Premise and Cloud. Therefore, beginning in the first quarter of 2014, the Company has reported its financial performance based on the new segments, Premise and Cloud, as described below. Prior period amounts have been presented on the same basis.
	The primary financial measures of performance of the segments are revenues and gross margin, which includes segment revenues less cost of sales. The Company does not allocate operating expenses to its segments as management does not use this information to measure the performance of the individual operating segments. In addition, total asset information by segment is not presented because the CEO does not use such segmented measures to allocate resources and assess performance. The accounting policies of reported segments are the same as those described in the summary of significant accounting policies. Revenue and cost of revenue are generally directly attributed to the segments. Cost of revenue is directly charged to the segments in most cases and, in certain cases, on a pro-rata basis based on revenue.
	The Premise segment sells and supports products and services for premise-based customers. This includes the Company’s premise-based IP and TDM telephony platforms, desktop devices and unified communications and collaboration (“UCC”) and contact centre applications that are deployed on the customer’s premise. Premise-based sales are typically sold as an initial sale of hardware and software, with ongoing recurring revenue from hardware and software maintenance and other managed services that we may also offer.
	The Cloud segment sells and supports products that are deployed in a cloud environment. The Cloud segment is comprised of a retail offering and a wholesale offering. The retail cloud offering, branded MiCloud, provides hosted cloud and related services directly to the end user. The Company is typically paid a monthly recurring fee for these services, which include UCC applications, voice and data telecommunications and desktop devices. The wholesale offering, branded Powered by Mitel, enables service providers to provide a range of hosted communications offerings to their end customers. The hosted offering include hosted PBX, voice and video calling, SIP Trunking, voice and video mail, call center, audio conferencing and video and web collaboration services. The wholesale cloud offering is also sold to large enterprise customers who run their own data centers in private cloud or hybrid cloud networks with management provided by Mitel, or one of Mitel’s channel partners. Revenue in the wholesale cloud offering is billed either as monthly recurring fees or as an upfront sale of hardware and software.

HEDGING ACTIVITIES	'
	20. HEDGING ACTIVITIES
	The Company operates globally, and therefore incurs expenses in currencies other than its various functional currencies and its U.S. dollar reporting currency. The Company has used, and may use in the future, foreign currency forward contracts to minimize the short-term impact of currency fluctuations on foreign currency receivables, payables and intercompany balances. These contracts are not entered into for speculative purposes, and are not treated as hedges for accounting purposes. Foreign currency contracts are recorded at fair value. Related foreign currency gains and losses are recorded in other income (expense), net, in the unaudited interim consolidated statements of operations.
	At March 31, 2014 and December 31, 2013, all of the Company’s outstanding forward contracts had a term of one month or less.
	At March 31, 2014, the Company held forward option contracts to sell Australian dollars and Euros at a fixed rate on a notional amount of $11.0 U.S. dollars. In addition, the Company held forward option contracts to buy British pounds sterling at a fixed rate on a total notional amount of $6.6 U.S. dollars. At March 31, 2014, the Company had a net unrealized gain on fair value adjustments on the outstanding forward contracts of less than $0.1.
	At December 31, 2013, the Company held forward option contracts to sell Australian dollars, British pounds sterling and Euros at a fixed rate on a notional amount of $21.0 U.S. dollars. In addition, the Company held forward option contracts to buy Canadian dollars and British pounds sterling at a fixed rate on a total notional amount of $7.1 U.S. dollars. At December 31, 2013, the Company had a net unrealized loss on fair value adjustments on the outstanding forward contracts of less than $0.1.

	In conjunction with the acquisition of Aastra, we reclassified service inventory from other current assets to inventory on the consolidated balance sheets. To conform to the current years’ presentation, $2.9 of service inventory, consisting of gross service inventory of $5.1 and a provision against service inventory of $2.2, was reclassified from other current assets to inventory at December 31, 2013.
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.
	Classification of unrecognized tax benefits
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-11 to include explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss carryforward or a tax credit carryforward exists. The ASU provides amendments to the Income Taxes subtopic of the FASB Accounting Standards Codification (“ASC”), such that generally, unrecognized tax benefits should be presented as a reduction of deferred tax assets created by net operating losses or tax credit carryforwards in the same jurisdiction. The Company adopted this ASU prospectively in the first quarter of 2014. The adoption did not have a material impact on the consolidated financial statements.
	Discontinued operations
	In April 2014, the FASB issued ASU 2014-08 to change the criteria for reporting discontinued operations such that disposals of small groups of assets will no longer qualify for discontinued operations presentation. The ASU provides amendments to the Presentation of Financial Statements and Property, Plant and Equipment subtopics of the FASB ASC. As a result of the ASU, only those disposals of components that represent a strategic shift that has or will have a major effect on the entity’s operations will be reported as discontinued operations. The Company will adopt this ASU prospectively, no later than the first quarter of 2015.

	-8	Included in accounts payable and accrued liabilities is $3.7 relating to accrued contingent consideration recorded for the acquisition of Telepo Ltd. by Aastra on January 20, 2014.
	-9	The amounts recorded for pension liability consist primarily of unfunded defined benefit pension plans in France and Germany. Excluded from the pension liability is a multi-employer defined benefit plan in Switzerland. As a result of the assets in the plan being pooled as well risk-sharing of the liabilities in the plan, the plan is considered a multi-employer defined benefit plan under U.S. GAAP and, as such, contributions are expensed as paid and no amount has been recorded as a pension liability as withdrawal from the plan was not considered probable at January 31, 2014 and March 31, 2014. At January 31, 2014 Aastra’s share of the plan’s assets and projected benefit obligation was $98.4 and $104.1, respectively.

Included in accounts payable and accrued liabilities is $3.7 relating to accrued contingent consideration recorded for the acquisition of Telepo Ltd. by Aastra on January 20, 2014.

[10]

The amounts recorded for pension liability consist primarily of unfunded defined benefit pension plans in France and Germany. Excluded from the pension liability is a multi-employer defined benefit plan in Switzerland. As a result of the assets in the plan being pooled as well risk-sharing of the liabilities in the plan, the plan is considered a multi-employer defined benefit plan under U.S. GAAP and, as such, contributions are expensed as paid and no amount has been recorded as a pension liability as withdrawal from the plan was not considered probable at January 31, 2014 and March 31, 2014. At January 31, 2014 Aastra's share of the plan's assets and projected benefit obligation was $98.4 and $104.1, respectively.
