Summary of significant accounting policies

3. Summary of significant accounting policies

The significant accounting policies used in the preparation of these consolidated financial statements are as follows:

a. Consolidation

These consolidated financial statements incorporate the financial statements of the Company and the entities controlled by the Company (its subsidiaries, including special purpose entities). Control exists when the Company has the power, directly or indirectly, to govern the financial and operating policies of an entity so as to obtain benefits from its activities. The financial statements of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that control ceases. All intercompany transactions and balances, income and expenses have been eliminated.

The Company applies the acquisition method to account for business combinations. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. The Company elects on an acquisition-by-acquisition basis whether to measure non-controlling interest at its fair value, or at its proportionate share of the recognized amount of identifiable net assets. Acquisition-related costs are expensed as incurred. Goodwill is initially measured as the excess of the aggregate of the consideration transferred and the fair value of non-controlling interest over the net identifiable assets acquired and liabilities assumed. If this consideration is negative, a bargain purchase gain is recognized immediately in profit or loss.

Special Purpose Entities (“SPE’s”) as defined by the IASB in SIC 12 Consolidation–Special Purpose Entities are entities which are created to accomplish a narrow and well-defined objective (e.g. to provide services to the operating entity). SPE’s are subject to consolidation when there is an indication that the other entity controls the SPE. The Company has determined that it controls certain SPE’s relating to service companies at its Mexican operations (4246136 Canada Inc., Servicios Especializados en Minas S.A. de C.V., Triturados Mineros del Noroeste S.A. de C.V. and Servicios Generales en Mineria S.A. de C.V.) and the accounts of those SPE’s are consolidated with those of the Company.

b. Segment reporting

An operating segment is a component of the Company that engages in business activities from which it may earn revenues and incur expenses, including revenues and expenses that relate to transactions with any of the Company’s other components. Determination of operating segments are based on the reports reviewed by the chief operating decision makers that are used to make strategic decisions about resources to be allocated to the segment and performance assessment, and for which discrete financial information is available. Unallocated items not directly attributable to a segment comprise mainly of corporate assets and head office expenses.

c. Presentation currency and functional currency

The Company’s presentation currency is the U.S. dollar (“USD”). The functional currency of the Company’s Canadian subsidiaries is the Canadian dollar (“CAD”), and the functional currency of its U.S., Mexican and British Virgin Island’s subsidiaries and SPE’s is the USD. The consolidated financial statements of the Company are translated into the presentation currency. Assets and liabilities have been translated using the exchange rate at period end, and income, expenses and cash flow items are translated using the rate that approximates the exchange rates at the dates of the transactions (the average rate for the period). All resulting exchange differences are recorded in the foreign currency translation reserve.

d. Foreign currency translations

Transactions in foreign currencies are translated into the entities’ functional currency at the exchange rate at the date of the transactions. Monetary assets and liabilities of the Company’s operations denominated in a currency other than the functional currency are translated at the rate in effect at the statement of financial position date, and non-monetary items at historic exchange rates at each transaction date. Revenue and expense items are translated at average exchange rates of the reporting period. Gains and losses on translation are charged to the statements of loss and comprehensive loss.

e. Revenue recognition

The following specific conditions must be met before revenue is recognized:

·	the title, specific risks and rewards of ownership have been transferred to the purchaser;

·	the Company does not retain continuing managerial involvement to the degree usually associated with ownership or effective control over the concentrate sold;

·	the amount of revenue and costs can be measured reliably; and

·	it is probable that the economic benefits associated with the transaction will flow to the Company.

The Company’s sales of concentrates are made under provisional pricing arrangements where the final sale prices are determined by quoted market prices in a period subsequent to the date of sale. In these circumstances, revenue from sales is recorded at the time of sale based on forward prices for the expected date of final settlement.

Subsequent variations in prices and metal quantities are recognized as revenue adjustments as they occur.

Revenue is recognized net of treatment and selling costs if payment of those amounts is enforced at the time of sale.

f. Defined benefit plans

The cost of defined benefit plans is determined using the projected unit credit method. The related pension liability recognized in the consolidated statement of financial position is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets.

Actuarial valuations for defined benefit plans are carried out annually. The discount rate applied in arriving at the present value of the pension liability represents the yield on high quality corporate bonds denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating the terms of the related pension liability.

Actuarial gains and losses arise from the difference between the actual long-term rate of return on plan assets for a period and the expected long-term rate of return on plan assets for that period, or from changes in actuarial assumptions used to determine the accrued benefit obligation. Actuarial gains and losses arising in the year are recognized in full in the period in which they occur, in other comprehensive income (loss) and retained earnings without recycling to the consolidated statement of loss and comprehensive loss in subsequent periods.

Current service cost, the recognized element of any past service cost, interest expense arising on the pension liability and the expected return on plan assets are recognized in the same line items in the consolidated statement of loss and comprehensive loss as the related compensation cost.

The values attributed to plan liabilities are assessed in accordance with the advice of independent qualified actuaries. Service costs arising from plan amendments are recognized immediately.

g. Share-based payments

The Company’s stock option plan allows its employees (including directors and officers) and non-employees to acquire shares of the Company. Accordingly, the fair value of the option is either charged to operations or capitalized to exploration or development expenditures, depending on the accounting for the optionee’s other compensation, with a corresponding increase in equity reserve.

The costs of equity-settled transactions with employees are measured by reference to the fair value at the date on which they are granted using the Black-Scholes Option Pricing Model.

The costs of equity-settled transactions are recognized, together with a corresponding increase in equity reserve, over the period in which the performance and/or service conditions are fulfilled, ending on the date on which the relevant employees become fully entitled to the award (the “vesting date”). The cumulative expense recognized for equity-settled transactions at each reporting date up to the vesting date reflects the Company’s best estimate of the number of equity instruments that will ultimately vest. The charge or credit for a period represents the movement in cumulative expense recognized as at the beginning and end of that period and the corresponding amount is represented in equity reserve. No expense is recognized for awards that do not ultimately vest.

Where the terms of an equity-settled award are modified, the minimum expense recognized is the expense as if the terms had not been modified. An additional expense is recognized for any modification which increases the total fair value of the share-based payment arrangement, or is otherwise beneficial to the employee as measured at the date of modification.

h. Income taxes

Income tax comprises of current and deferred tax. Income tax is recognized in the consolidated statement of loss and comprehensive loss except to the extent that it relates to items recognized directly in other comprehensive income (loss) or directly in equity, in which case the income tax is also recognized directly in other comprehensive income (loss) or equity, respectively.

The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the end of the reporting period in the countries where the Company’s subsidiaries operate and generate taxable profit. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.

Deferred income tax is recognized in respect of temporary differences between the carrying amount of assets and liabilities in the consolidated statement of financial position and the corresponding tax bases used in the computation of taxable profit. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantively enacted at the consolidated statement of financial position date and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled.

Deferred income tax assets are recognized for all deductible temporary differences, carry-forward of unused tax credits and unused tax losses to the extent it is probable future taxable profits will be available against which they can be utilized.

The Company did not recognize any deferred income taxes relating to its investments in subsidiaries.

Deferred tax assets and liabilities are offset where they relate to income taxes levied by the same taxation authority and the Company has the legal right and intent to offset.

i. Earnings/loss per share

Basic earnings/loss per share is calculated by dividing the net earnings/loss for the period attributable to equity owners of the Company by the weighted average number of common shares outstanding during the period.

Diluted earnings/loss per share is calculated by adjusting the weighted average number of common shares outstanding for dilutive instruments. The number of shares included with respect to options, warrants and similar instruments is computed using the treasury stock method. The treasury stock method, which assumes that outstanding stock options and warrants with an average exercise price below the market price of the underlying shares, are exercised and the assumed proceeds are used to repurchase common shares of the Company at the average market price of the common shares for the period. The Company’s potentially dilutive common shares comprise stock options granted to employees, and warrants.

j. Comprehensive income (loss)

Comprehensive income (loss) is the change in the Company’s net assets that results from transactions, events and circumstances from sources other than the Company’s shareholders and includes items that would not normally be included in net earnings such as foreign currency gains or losses related to the Company’s net investment in foreign operations and unrealized gains or losses on available-for-sale securities net of tax. The Company’s comprehensive income (loss), components of other comprehensive income and cumulative translation adjustments are presented in the consolidated statements of comprehensive income (loss) and the consolidated statements of changes in equity.

k. Inventories

Concentrates, ore stockpile, and spare parts and supplies are valued at the lower of cost and estimated net realizable value. Cost for concentrates and ore stockpile includes all direct costs incurred in production including direct labour and materials, freight, depreciation and amortization and directly attributable overhead costs determined on a weighted average basis for the Mexican operations and first in, first out method for the U.S. operations. Cost for spare parts and supplies are determined using the first in, first out method. Net realizable value is calculated as the estimated price at the time of sale based on prevailing and future metal prices less estimated future production costs to convert inventories into saleable form.

Any write-downs of inventory to net realizable value are recorded as cost of sales. If there is a subsequent increase in the value of inventories, the previous write-downs to net realizable value are reversed to the extent that the related inventory has not been sold.

Ore stockpile represents ore that has been extracted from the mine and is available for further processing. Costs added to ore stockpile are valued based on current mining cost per tonne incurred up to the point of stockpiling the ore and are removed at the average cost per tonne. Ore stockpile is verified by periodic surveys and physical counts.

Materials and supplies inventory are valued at the lower of cost and net realizable value, where cost is determined using the first-in-first-out method. Any provision for obsolescence is determined by reference to specific items of stock. A regular review is undertaken to determine the extent of any provision for obsolescence by comparing those items to their net realizable value. If carrying value exceeds net realizable value, a write-down is recognized.

l. Investments

An associate is an entity over which the Company has significant influence and that is neither a subsidiary nor an interest in a joint venture. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies.

Investments in companies over which the Company exercises neither control nor significant influence and are designated as available-for sale financial instruments are recorded at fair value. Unrealized gains and losses on available-for-sale financial instruments are recognized in other comprehensive income (loss), unless the decrease in value is significant or prolonged, in which case, the loss is recorded in the statements of loss and comprehensive loss.

m. Property, plant and equipment

(i) Producing mining interests

Producing mining interests are carried at cost less accumulated depletion and amortization and accumulated impairment losses. Following the completion of commissioning, the costs related to the mining interests are depleted and charged to operations on the unit of production method as a proportion of estimated recoverable mineral reserves.

Completion of the commissioning is deemed to have occurred when major mine and processing plant components are completed, operating results are being achieved consistently for a period of time and that there are indicators that these operational results, including mill capacity and recovery, will be sustainable in the future.

Construction in progress is not depreciated until the assets are ready for their intended use.

(ii) Non-producing mining interests

The Company follows the method of accounting for its non-producing mining interests whereby all costs, net of incidental revenues, relating to the acquisition, exploration and development are deferred and capitalized by property until the property to which they directly relate is placed into production, sold, discontinued or subject to a condition of impairment.

In the event that a mining interest is placed into production, capitalization of costs ceases, the costs are transferred to producing mining interests and the mining interest is depleted on a unit of production basis. The recoverability of amounts is dependent upon the discovery of economically recoverable mineral reserves, the ability of the Company to finance the development of the properties, and on the future profitable production or proceeds from the disposition thereof.

(iii) Plant and equipment

Property, plant and equipment are carried at cost less accumulated depreciation and accumulated impairment losses.

When parts of an item of property, plant and equipment have different useful lives, they are accounted for as separate assets (major components) of property, plant and equipment.

The cost of replacing a part of an item of property, plant and equipment is recognized in the carrying amount of the item if it is probable that the future economic benefits embodied within that part will flow to the Company, and its cost can be measured reliably. The carrying amount of the replaced part is derecognized. Repairs and maintenance are charged to the consolidated statement of loss and comprehensive loss during the period in which they are incurred.

Depreciation is recorded over the estimated useful life of the asset as follows:

•	Mining interests – unit of production based upon estimated proven and probable reserves

•	Plant and equipment – 3 – 30 years over straight line basis

•	Corporate office equipment – 3 – 10 years over straight line basis

Residual values, method of amortization and useful lives of the assets are reviewed annually and adjusted if appropriate.

(iv) Impairment of mining interests

The Company reviews and evaluates the carrying values of its tangible and intangible assets to determine whether there is an indication of impairment. For exploration and evaluation assets, indication includes but is not limited to expiration of the right to explore, substantive expenditure in the specific area is neither budgeted nor planned, and if the entity has decided to discontinue exploration activity in the specific area.

When the carrying value of assets exceeds the recoverable amount, the carrying value of the assets is reduced to the recoverable amount. The recoverable amount takes into account a market participant’s ability to generate economic benefits by using the asset in its highest and best use of the asset. To achieve this, the recoverable amount is the higher of value in use (being the net present value of expected pre-tax future cash flows of the relevant asset) and fair value less costs to sell the asset.

If, after the Company has previously recognized an impairment loss, circumstances indicate that the recoverable amount of the impaired assets is greater than the carrying amount, the Company reverses the impairment loss by the amount the revised fair value exceeds its carrying amount, to a maximum of the previous impairment loss. In no case shall the revised carrying amount exceed the original carrying amount, after depreciation or amortization, that would have been determined if no impairment loss had been recognized.

n. Decommissioning provision

The Company recognizes contractual, statutory and legal obligations associated with retirement of mining properties when those obligations result from the acquisition, construction, development or normal operation of the assets. Initially, the decommissioning provision is recognized at its fair value in the period in which it is incurred. Upon initial recognition of the liability, the corresponding decommissioning provision is added to the carrying amount of that asset and the cost is amortized as an expense over the economic life of the related asset. Following the initial recognition of the decommissioning provision, the periodic unwinding of the discount is recognized in the consolidated statement of loss and comprehensive loss and adjusted for changes to the amount or timing of the underlying cash flows to settle the obligation.

o. Financial instruments

The Company classifies its financial instruments into one of the following categories: fair value through profit or loss (“FVTPL”) (assets and liabilities), assets available-for-sale, loans and receivables, assets held-to-maturity and other financial liabilities. All financial instruments are measured at fair value on initial recognition.

Financial assets and liabilities designated as FVTPL are subsequently measured at fair value with changes in fair value recognized in net earnings. Financial assets designated as “available-for-sale” are subsequently measured at fair value with changes in fair value recognized in other comprehensive income (loss), net of tax. Transaction costs for FVTPL financial assets and liabilities are recognized in income when incurred.

Financial assets designated as “loans and receivables” or “held-to-maturity”, and financial liabilities designated as “other financial liabilities” are recorded at amortized cost. Transaction costs from loans and receivables and other financial liabilities offset the carrying amount of the related financial assets or liabilities.

The Company has classified cash and cash equivalents and trade and other receivables as “loans and receivables”, trade and other payables are classified as “other financial liabilities”, and investments in equity instruments as “available-for-sale”.

p. Borrowing costs

Borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset are capitalized as part of the cost of that asset and amortized over the expected useful life of that asset. Other borrowing costs not directly attributable to a qualifying asset are expensed in the period incurred.

q. Provisions

Provisions are recognized when the Company has a present obligation (legal or constructive) that has arisen as a result of a past event and it is probable that a future outflow of resources will be required to settle the obligation, provided that a reliable estimate can be made of the amount of the obligation.

Provisions are measured at the present value of the expenditures expected to be required to settle the obligation using a pre-tax rate that reflects current market assessments of the time value of money and the risk specific to the obligation. The increase in the provision due to passage of time is recognized as interest expense.

r. Related party transactions

Parties are considered to be related if one party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operating decisions. Parties are also considered to be related if they are subject to common control or common significant influence, and related parties may be individuals or corporate entities. A transaction is considered to be a related party transaction when there is a transfer of resources or obligations between related parties. Related party transactions that are in the normal course of business and have commercial substance are measured at the exchange amount.

Significant accounting judgments and estimates The preparation of financial statements in conformity with IFRS requires management to make judgments and estimates that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The areas which require management to make significant judgments, estimates and assumptions in determining carrying values include, but are not limited to: (i) Reserves and resources Proven and probable reserves are the economically mineable parts of the Company’s measured and indicated mineral resources. The Company estimates its proven and probable reserves and measured and indicated and inferred mineral resources based on information compiled by appropriately qualified persons. The information relating to the geological data on the size, depth and shape of the ore bodies requires complex geological judgments to interpret the data. The estimation of future cash flows related to proven and probable reserves is based upon factors such as estimates of foreign exchange rates, commodity prices, future capital requirements and production costs along with geological assumptions and judgments made in estimating the size, grade and recovery of the ore bodies. Changes in the proven and probable reserves or measured, indicated and inferred mineral resources estimates may impact the carrying value of mining properties and equipment, depletion and amortization, impairment assessments and the timing of decommissioning provisions. (ii) Depletion and amortization Mining properties are depleted using the unit-of-production method over a period not to exceed the estimated life of the ore body based on estimated recoverable reserves. Property, plant and equipment are depreciated, net of residual value over their estimated useful life but do not exceed the related estimated life of the mine based on estimated recoverable mineral reserves. The calculation of the units of production rate, and therefore the annual depletion and amortization expense, could be materially affected by changes in the underlying estimates. Changes in estimates can be the result of actual future production differing from current forecasts of future production and expansion of mineral reserves through exploration activities. Significant judgment is involved in the determination of useful life and residual values for the computation of depletion and amortization. No assurance can be given that actual useful lives and residual values will not differ significantly from current assumptions. (iii) Decommissioning provision The Company assesses its decommissioning provision on an annual basis or when new material information becomes available. Mining and exploration activities are subject to various laws and regulations governing the protection of the environment. In general, these laws and regulations are continually changing and the Company has made, and intends to make in the future, expenditures to comply with such laws and regulations. Accounting for decommissioning provision requires management to make estimates of the time and future costs the Company will incur to complete the rehabilitation work required to comply with existing laws and regulations at each mining operation. Also, future changes to environmental laws and regulations could increase the extent of rehabilitation work required to be performed by the Company. Increases in future costs could materially impact the amounts charged to operations for decommissioning provision. The provision represents management’s best estimate of the present value of the future decommissioning provision. The actual future expenditures may differ from the amounts currently provided. (iv) Share-based payments The amount expensed for share-based compensation is based on the application of a recognized option valuation formula, which is highly dependent on, amongst other things, the expected volatility of the Company’s registered shares, estimated forfeitures, and the expected life of the options. The Company uses an expected volatility rate for its shares based on past stock trading data, adjusted for future expectations, and actual volatility may be significantly different. The resulting value calculated is not necessarily the value that the holder of the option could receive in an arm’s length transaction, given that there is no market for the options and they are not transferable. It is management’s view that the value derived is highly subjective and dependent entirely upon the input assumptions made. (v) Income taxes Preparation of the consolidated financial statements requires an estimate of income taxes in each of the jurisdictions in which the Company operates. The process involves an estimate of the Company’s current tax exposure and an assessment of temporary differences resulting from differing treatment of items, such as depletion and amortization, for tax and accounting purposes, and when they might reverse. These differences result in deferred tax assets and liabilities that are included in the Company’s consolidated statements of financial position. An assessment is also made to determine the likelihood that the Company’s future tax assets will be recovered from future taxable income. To the extent that recovery is not considered likely, the related tax benefits are not recognized. Judgment is required to continually assess changing tax interpretations, regulations and legislation, to ensure liabilities are complete and to ensure assets, net of valuation allowances, are realizable. The impact of different interpretations and applications could be material. (vi) Commercial production The determination of timing on which a mining property enters into commercial production is a significant judgment since capitalization of development costs ceases and revenue recognition begins upon declaration of commercial production. As a mining property is constructed, development costs incurred are capitalized while pre-production costs and revenues are capitalized and accumulated into such development costs. Commercial production is declared once the mining property is available for its intended use on a commercial scale as defined by management. Revenue recognition and depletion of the mining property begins when commercial production has been achieved.

Changes in accounting policies and recent accounting pronouncements The following are future changes in accounting policies not yet effective as at December 31, 2017: (i) Financial instruments IFRS 9 - Financial Instruments - The standard was issued in its final version by the IASB in July 2014 bringing together the classification and measurement, impairment and hedge accounting phases of the IASB’s project to replace IAS 39, “Financial instruments: recognition and measurement” (“IAS 39”). The standard retains but simplifies the mixed measurement model and establishes two primary measurement categories for financial assets: amortized cost and fair value. The mandatory effective date of IFRS 9 would be annual periods beginning on or after January 1, 2018, with early adoption permitted. The Company completed assessing the impact of this standard and do not expect the Company’s consolidated financial statements to be significantly affected by IFRS 9. (ii) Revenue from contracts with customers IFRS 15 - Revenue from Contracts with Customers - The final standard on revenue from contracts with customers was issued in May 2014 and is effective for annual reporting periods beginning on or after January 1, 2018 for public entities with early adoption permitted. The standard covers principles that an entity shall apply to report useful information to users of financial statements about the nature, amount, timing, and uncertainty of revenue and cash flows arising from a contract with a customer. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt the guidance. The Company completed assessing the impact of this standard and do not expect the Company’s consolidated financial statements to be significantly affected by IFRS 15. (iii) Leases IFRS 16 - Leases - The standard on leases was issued in January 2016 and is effective for annual reporting periods beginning on or after January 1, 2019 for public entities with early adoption permitted, provided IFRS 15 has been applied or is applied at the same date as IFRS 16. The standard requires lessees to recognize assets and liabilities for most leases. The Company is assessing the impact of this standard, along with timing of adoption of IFRS 16.

On March 2, 2017, the Company entered into an option acquisition agreement with Impulsora Minera Santacruz S.A. de C.V., a wholly-owned subsidiary of Santacruz Silver Mining Ltd. (“Santacruz”), to acquire an existing option with Minera Hochschild Mexico S.A. de C.V. (“Hochschild”) for the right to acquire a 100% interest of the San Felipe property located in Sonora, Mexico for total consideration of $15 million in cash, payable in two installments. The purchase of the option of $5 million to Santacruz plus an initial option payment of $2 million to Hochschild, plus applicable VAT, was paid with cash on hand by the Company in March while the final option payment of $8 million, plus applicable VAT, was payable to Hochschild on or before December 15, 2017. On December 1, 2017, the final option payment of $8 million plus applicable VAT was amended to become option payments of $0.5 million payable on January 1, 2018, $0.5 million payable on April 1, 2018, $1.0 million payable on July 1, 2018, with the remaining balance of $6.0 million payable on or before December 31, 2018.

Effective December 19, 2017, the San Rafael mine declared commercial production which the Company defined as operating at an average of 80% designed production capacity with saleable concentrate recoveries within 5% of its mining feasibility study over a two week period. The Company transferred $31.6 million in net book value from non-producing properties to mining interests, net of pre-commercial production revenue of $4.0 million and historical carrying value of $25.2 million.

Non-current assets are tested for impairment or impairment reversals when events or changes in circumstances suggest that the carrying amount may not be recoverable. A write-down of $0.2 million related to the U.S. operations was recorded for the year ended December 31, 2017 as a result of writing down carrying amounts of equipment to recoverable amounts. No other impairment or impairment reversal indicators were identified for the year ended December 31, 2017.

The amount of borrowing costs capitalized as property, plant and equipment was $0.7 million during the year ended December 31, 2017 (2016: nil).

Post-employment benefit obligations

11. Post-employment benefit obligations

The Company maintains two non-contributory defined benefit pension plans covering substantially all employees at its U.S. operating subsidiary, U.S. Silver – Idaho, Inc. One plan covers salaried employees and one plan covers hourly employees. Benefits for the salaried plan are based on salary and years of service. Hourly plan benefits are based on negotiated benefits and years of service. The Company’s funding policy is to contribute annually the minimum amount prescribed, as specified by applicable regulations. The expected average service life of the active plan participants as at December 31, 2017 is approximately 9 years.

The amounts recognized in the consolidated statements financial position are as follows:

	December 31,		December 31,

A 1% decrease in discount rate would have resulted in approximately $4.4 million increase in the defined benefit obligation from $26.7 million to $31.1 million as at December 31, 2017 (2016: $3.8 million increase in the defined benefit obligation from $23.9 million to $27.7 million). A 1% increase in future salary increases would have resulted in approximately $0.1 million increase in the defined benefit obligation from $26.7 million to $26.8 million as at December 31, 2017 (2016: $0.1 million increase in the defined benefit obligation from $23.9 million to $24.0 million).

Plan assets are fully comprised of pooled or mutual funds. The expected return on plan assets at 4.3% (2016: 4.2%) is determined by considering the expected returns available on the assets underlying the current investment policy. Expected yield on fixed interest investments is based on gross redemption yields as at the end of the reporting period. Expected returns on equity investments reflect long-term real rates of return in the market.

Expected contributions to pension benefit plans for the year ended December 31, 2018 are approximately $0.8 million. For the year ended December 31, 2017, the actuarial losses charged to other comprehensive loss are $0.4 million (2016: actuarial gains of $1.6 million charged to other comprehensive income).

12. Decommissioning provision

The decommissioning provision consists of land rehabilitation, demolition of buildings and mine facilities, and related costs. Although the ultimate amount of the decommissioning provision is uncertain, the fair value of these obligations is based on information currently available, including closure plans and the Company’s interpretation of current regulatory requirements.

Fair value is determined based on the net present value of future cash expenditures upon reclamation and closure. Reclamation and closure costs are capitalized into property, plant and equipment depending on the nature of the asset related to the obligation and amortized over the life of the related asset.

The decommissioning provision relates to reclamation and closure costs of the Company’s Cosalá Operations and Galena Complex. The decommissioning provision is estimated at an undiscounted amount of $5.6 million, over a period of 2 to 12 years, and discounted using a risk free rate varying from 2.3% to 7.6%.

Under the plan, the Board of Directors determines the term of a stock option to a maximum of 10 years, the period of time during which the options may vest and become exercisable as well as the option exercise price which shall not be less than the closing price of the Company’s share on the Toronto Stock Exchange on the date immediately preceding the date of grant. The Compensation Committee determines and makes recommendations to the Board of Directors as to the recipients of, and nature and size of, share-based compensation awards in compliance with applicable securities law, stock exchange and other regulatory requirements.

A summary of changes in the Company’s outstanding stock options is presented below:

c. Share-based payments

The weighted average fair value at grant date of the Company’s stock options granted during the year ended December 31, 2017 was $1.58 (2016: $1.08).

The Company used the Black-Scholes Option Pricing Model to estimate fair value using the following weighted-average assumptions:

	Year ended			Year ended
	December 31,			December 31,
	2017			2016

Expected stock price volatility ⁽¹⁾		83	%		83	%
Risk free interest rate		0.87	%		0.47	%
Expected life	3 years			3 years

Share-based payments included in cost of sales	$	-		$	19
Share-based payments included in general and
administrative expenses		1,491			566
Total share-based payments	$	1,491		$	585

(1)	Expected volatility has been based on historical volatility of the Company’s publicly traded shares.

d. Warrants

The warrants that are issued and outstanding as at December 31, 2017 are as follows:

Number of	Exercise	Issuance	Expiry
warrants	price (CAD)	date	date
742,883	4.68	Jul 2016	Jun 14, 2021

395,486	1.56	May 2015	May 27, 2018
5,167,391

The 388,886 warrants issued in June 2016 are broker warrants where each broker warrant is exercisable for one broker unit at an exercise price of $4.20 CAD for a period of two years. Each broker unit consisted of one common share and one quarter of one common share purchase warrant where each whole warrant is exercisable for one common share at an exercise price of $4.68 CAD for a period of five years starting on June 9, 2016.

The 224,728 warrants issued in July 2016 are broker warrants where each broker warrant is exercisable for one broker unit at an exercise price of $4.20 CAD for a period of two years. Each broker unit consisted of one common share and one quarter of one common share purchase warrant where each whole warrant is exercisable for one common share at an exercise price of $4.68 CAD for a period of five years starting on June 14, 2016.

e. Restricted Share Units:

The Company has a Restricted Share Unit Plan under which eligible directors, officers and key employees of the Company are entitled to receive awards of restricted share units. Each restricted share unit is equivalent in value to the fair market value of a common share of the Company on the date of grant with the value of each cash settled award charged to compensation expense over the period of vesting. At each reporting date, the compensation expense and associated liability (which is included in trade and other long-term liabilities in the consolidated statement of financial position) are adjusted to reflect changes in market value. As at December 31, 2017, 208,722 (2016: 351,856) restricted share units are outstanding at an aggregate value of $0.8 million (2016: $0.9 million).

f. Deferred Share Units:

The Company has a Deferred Share Unit Plan under which eligible directors of the Company are entitled to receive awards of deferred share units on a quarterly basis as payment for 20% to 100% of their director fees earned. Deferred share units are settled in either cash or common shares at the Company’s discretion when the director leaves the Company’s Board of Directors. The Company recognizes a cost in director fees and a corresponding increase in equity reserve upon issuance of deferred share units. As at December 31, 2017, 286,920 (2016: 240,313) deferred share units are issued and outstanding.

On December 22, 2017, the United States government enacted a tax reform with changes to reducing the corporate income tax rate from 35% to 21% and repealing the corporate alternative minimum tax effective January 1, 2018. The Company assessed the impact of the tax reform and recognized a deferred tax asset of $0.6 million as at December 31, 2017 with respect to recoverable alternative minimum tax credits. Impact of the tax reform may differ due to changes in interpretations and assumptions made along with guidance which may subsequently be issued.

The Company’s net deferred tax liability relates to the Mexican mining royalty and arises principally from the following:

	December 31,		December 31,
	2017		2016

Property, plant and equipment	$	900	$	972

Financial risk management

19. Financial risk management

a. Financial risk factors

The Company’s risk exposures and the impact on its financial instruments are summarized below:

(i) Credit Risk

Credit risk is the risk of loss associated with a counterparty’s inability to fulfill its payment obligations. The Company’s credit risk is primarily attributable to cash and cash equivalents and trade and other receivables. The credit risk on cash and cash equivalents is limited because the Company invests its cash in deposits with well-capitalized financial institutions with strong credit ratings in Canada and the United States. Under current concentrate offtake agreements, risk on trade receivables related to concentrate sales is managed by receiving payments for 85% to 100% of the estimated value of the concentrate within one month following the time of shipment.

As of December 31, 2017, the Company’s exposure to credit risk with respect to trade receivables amounts to $3.8 million (December 31, 2016: $2.1 million). The Company believes credit risk for Mexican Value Added Taxes of $2.8 million (December 31, 2016: $1.6 million) is not significant as they relate to current amounts receivable from Mexican taxation authorities. There are no receivables that are past due and the Company has no allowance for doubtful accounts at December 31, 2017 and December 31, 2016.

(ii) Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they arise. The Company’s approach to managing liquidity risk is to ensure that it will have sufficient liquidity to meet liabilities when due. The Company’s liquidity requirements are met through a variety of sources, including cash, cash generated from operations, existing credit facilities and debt and equity capital markets. The Company’s trade payables have contractual maturities of less than 30 days and are subject to normal trade terms.

The following table presents the contractual maturities of the Company’s financial liabilities on an undiscounted basis:

	December 31, 2017
			Less than						Over 5
	Total		1 year		2-3 years		4-5 years		years

Trade and other payables	$	10,393	$	10,393	$	-	$	-	$	-
Pre-payment facility		15,000		4,000		11,000		-		-
Interest on pre-payment facility		1,601		856		745		-		-
Leases		1,438		290		563		540		45
Other long-term liabilities		564		-		95		-		469
	$	28,996	$	15,539	$	12,403	$	540	$	514

(iii) Market risk

Market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices. Market risk comprises three types of risk: interest rate risk, currency risk and price risk.

(1)	Interest rate risk

The Company is not subject to significant interest rate risk as the existing credit facilities have a fixed interest rate.

(2)	Currency risk

As at December 31, 2017, the Company is exposed to foreign currency risk through financial assets and liabilities denominated in CAD and Mexican pesos (“MXP”):

Financial instruments that may impact the Company’s net earnings or other comprehensive income due to currency fluctuations include CAD and MXP denominated assets and liabilities which are included in the following table:

	As at December 31, 2017
	CAD		MXP

Cash and cash equivalents	$	1,436	$	1,681
Trade and other receivables		19		2,814
Trade and other payables		1,831		4,385

As at December 31, 2017, the CAD/USD and MXP/USD exchange rates were 1.25 and 19.74, respectively. The sensitivity of the Company’s net loss and comprehensive loss due to changes in the exchange rates as at December 31, 2017 is included in the following table:

	CAD/USD			MXP/USD
	Exchange rate			Exchange rate
		+/- 10%			+/- 10%

Approximate impact on:
Net loss	$	732		$	850
Other comprehensive loss		(93	)		110

The Company may, from time to time, employ derivative financial instruments to manage exposure to fluctuations in foreign currency exchange rates.

(3)	Price risk

Price risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices (other than those arising from interest rate risk or currency risk), whether those changes are caused by factors specific to the individual financial instrument or its issuer, or factors affecting all similar financial instruments in the market. As at December 31, 2017, the Company had certain amounts related to the sales of concentrates that have only been provisionally priced. A ±10% fluctuation in silver, zinc, lead, and copper prices would affect trade receivables by approximately $0.4 million (2016: $0.2 million). The Company may use derivatives to manage its exposure to price risk.

b. Fair values

The fair value of cash, restricted cash, trade and other payables, credit facilities and other long-term liabilities approximate their carrying amounts. The methods and assumptions used in estimating the fair value of other financial assets and liabilities are as follows:

·	Cash and cash equivalents: The fair value of cash equivalents is valued using quoted market prices in active markets. The Company’s cash equivalents consist of money market accounts held at financial institutions which have original maturities of less than 90 days.

Trade and other receivables: The fair value of trade receivables from silver sales contracts that contain provisional pricing terms is determined using the appropriate quoted forward price from the exchange that is the principal active market for the particular metal. As such, there is an embedded derivative feature within trade receivables.

·	Available-for-sale investment: Investment in publicly quoted equity securities have been marked to market based on the trading price as at December 31, 2017.

·	Long-term investments: The fair value of long-term investments is determined based on the closing price of each security at the balance sheet date. The closing price is a quoted market price obtained from the exchange that is the principal active market for the particular security.

Embedded derivatives: Revenues from the sale of metals produced since the commencement of commercial production are based on provisional prices at the time of shipment. Variations between the price recorded at the time of sale and the actual final price received from the customer are caused by changes in market prices for metals sold and result in an embedded derivative in revenues and accounts receivable.

Derivatives: The Company uses derivative and non-derivative instruments to manage financial risks, including commodity, interest rate, and foreign exchange risks. The use of derivative contracts is governed by documented risk management policies and approved limits. The Company does not use derivatives for speculative purposes. The fair value of the Company’s derivative instruments is based on quoted market prices for similar instruments and at market prices at the valuation date.

The fair value hierarchy establishes three levels to classify the inputs to valuation techniques used to measure fair value:

·	Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 inputs are quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, inputs other than quoted prices that are observable for the asset or liability (for example, interest rate and yield curves observable at commonly quoted intervals, forward pricing curves used to value currency and commodity contracts and volatility measurements used to value option contracts), or inputs that are derived principally from or corroborated by observable market data or other means.

·	Level 3 inputs are unobservable (supported by little or no market activity).

	December 31,		December 31,
	2017		2016

Level 1
Cash and cash equivalents	$	9,325	$	24,055
Restricted cash		331		151

Capital management

21. Capital management

Capital is defined as equity. The Company’s objectives when managing its capital are to safeguard its ability to continue as a going concern and to maximize the value for its shareholders.

The Company’s activities have been funded so far through debt and equity financing based on cash needs, and through operations. The Company typically sells its shares by way of private placement. There were no changes in these objectives, policies and processes used to manage capital during the year.

The Company manages its capital structure and determines its capital requirements in light of the changing economic conditions and the risk characteristics of its assets. To reach its objectives the Company may have to maintain or adjust its capital structure by issuing new share capital or new debt.

At this stage of its development, it is the policy of the Company to preserve cash to fund its operations and not to pay dividends. As of December 31, 2017 and 2016, the Company is not subject to any externally imposed capital requirements.

The following summarizes the Company’s capital structure:

	December 31,		December 31,
	2017		2016

Equity attributable to shareholders of the Company	$	88,058	$	87,144

Contingencies Due to the size, complexity and nature of the Company’s operations, various legal and tax matters arise in the ordinary course of business. The Company accrues for such items when a liability is both probable and the amount can be reasonably estimated. In November 2010, the Company received a reassessment from the Mexican tax authorities related to its Mexican subsidiary, Minera Cosalá, for the year ended December 31, 2007. The tax authorities disallowed the deduction of transactions with certain suppliers for an amount of approximately $10.0 million (MXP 196.8 million), of which $4.3 million (MXP 84.4 million) would be applied against available tax losses. The Company appealed this reassessment and the Mexican tax authorities subsequently reversed $4.8 million (MXP 94.6 million) of their original reassessment. The remaining $5.2 million (MXP 102.2 million) consists of $4.3 million (MXP 84.4 million) related to transactions with certain suppliers and $0.9 million (MXP 17.8 million) of value added taxes thereon. The Company appealed the remaining reassessment with the Mexican Tax Court in December 2011. The Company may be required to post a bond of approximately $0.9 million (MXP 17.8 million) to secure the value added tax portion of the reassessment. The deductions of $4.3 million (MXP 84.4 million), if denied, would be offset by available tax losses. No amount has been recognized in the consolidated financial statements as the Company believes it is not likely that the reassessment will be upheld by the Tax Court. The Company filed an amparo lawsuit against the resolution and it waits for final resolution by the tax authorities currently under motion for review.

m. Property, plant and equipment

(i) Producing mining interests

Construction in progress is not depreciated until the assets are ready for their intended use.

(ii) Non-producing mining interests

(iii) Plant and equipment

Property, plant and equipment are carried at cost less accumulated depreciation and accumulated impairment losses.

When parts of an item of property, plant and equipment have different useful lives, they are accounted for as separate assets (major components) of property, plant and equipment.

Depreciation is recorded over the estimated useful life of the asset as follows:

•	Mining interests – unit of production based upon estimated proven and probable reserves

•	Plant and equipment – 3 – 30 years over straight line basis

•	Corporate office equipment – 3 – 10 years over straight line basis

Residual values, method of amortization and useful lives of the assets are reviewed annually and adjusted if appropriate.

(iv) Impairment of mining interests

The following specific conditions must be met before revenue is recognized:

·	the title, specific risks and rewards of ownership have been transferred to the purchaser;

·	the Company does not retain continuing managerial involvement to the degree usually associated with ownership or effective control over the concentrate sold;

·	the amount of revenue and costs can be measured reliably; and

·	it is probable that the economic benefits associated with the transaction will flow to the Company.

Subsequent variations in prices and metal quantities are recognized as revenue adjustments as they occur.

Revenue is recognized net of treatment and selling costs if payment of those amounts is enforced at the time of sale.
