Silver Wheaton Remains Confident in Business Structure Following Receipt of CRA Proposal Letter

VANCOUVER, July 6, 2015 /PRNewswire/ – Silver Wheaton Corp. (“Silver Wheaton” or the “Company”) (TSX:SLW) (NYSE: SLW) announces that it has received a proposal letter dated July 6, 2015 (the “Proposal”) from the Canada Revenue Agency (the “CRA”) in which the CRA is proposing to reassess Silver Wheaton under various rules contained in the Income Tax Act (Canada).

The Proposal outlines CRA’s position that the transfer pricing provisions of the Income Tax Act (Canada) relating to income earned by our foreign subsidiaries outside of Canada should apply such that the income of Silver Wheaton subject to tax in Canada should be increased for the 2005 to 2010 taxation years (the “Relevant Taxation Years”) by approximately Cdn$715 million (US$567 million). The issuance of the Proposal does not require the Company to pay any amount to the CRA at this time.

Management believes that the Company has filed its tax returns and paid applicable taxes in compliance with Canadian tax law. Silver Wheaton intends to vigorously defend its tax filing positions and is now in the process of preparing its response to the Proposal.

“We remain confident in our business structure which we believe is consistent with that typically used by Canadian companies, including Canadian streaming companies, that have international operations,” said Randy Smallwood, President and Chief Executive Officer of Silver Wheaton.

“Generally a company is taxable in Canada on its income earned in Canada, while non-Canadian income earned by foreign subsidiaries is not subject to Canadian income tax. However, with this Proposal, the CRA is seeking to tax, within Canada, streaming income earned outside of Canada by our foreign subsidiaries related to mines located outside of Canada,” added Smallwood.

Failing a resolution at the Proposal stage, the CRA may proceed to issue notices of reassessment for one or more of the Relevant Taxation Years. If the CRA reassesses Silver Wheaton on the basis outlined in the Proposal, and assuming that Silver Wheaton would be assessed taxes on the foreign subsidiaries’ income on the same basis as its Canadian income, Silver Wheaton currently estimates on a preliminary basis that it would be subject to federal and provincial tax of approximately US$150 million in respect of the Relevant Taxation Years. The Proposal also indicates that the CRA is seeking to apply transfer pricing penalties of approximately Cdn$72 million (US$57 million) in respect of the Relevant Taxation Years. The Proposal does not indicate the amount of interest or other penalties in respect of the Relevant Taxation Years. Further, taxation years subsequent to 2010 remain open to audit by the CRA.

Should Silver Wheaton receive a notice of reassessment from the CRA based upon the Proposal, we intend to file a notice of objection within the required 90 day period provided under the Income Tax Act (Canada). In such a circumstance, Silver Wheaton would be required to pay 50% of the reassessed amount of tax, interest and penalties. This amount, plus interest, would be refunded if the Company were ultimately successful in challenging a reassessment. Any notice of objection would be reviewed by the CRA’s Appeals Division. Silver Wheaton also has the right to appeal directly to the Tax Court of Canada 91 days after the date of filing of any notice of objection.

The timing for the Proposal process, the CRA appeals process and/or court process (if necessary following the issuance by CRA of any notices of reassessment), is uncertain. Regardless of the timing, Silver Wheaton intends to vigorously defend its tax filing positions.

The following Q&A provides additional information on the CRA Proposal.

What is a proposal letter?

A proposal letter is not a reassessment but a letter which sets out the possible adjustments to the taxpayer’s income and the CRA’s reasons for a proposed reassessment.

Do we have to pay any amounts to the CRA now?

No, we are not required to pay any amounts to the CRA now.

When would we have to pay any amounts to the CRA?

If the CRA issues one or more notices of reassessment, and we object to such notices of reassessment, we would be required to pay 50% of the reassessed tax, interest and penalties. This amount would be refunded if we were ultimately successful in challenging the reassessment. If we do not object to the notice of reassessment, we will be required to pay the full reassessed amount.

For clarity, if CRA issues one or more notices of reassessment based on the Proposal, the Company intends to file notices of objection.

What further details can we provide on the Proposal?

The CRA is disputing our structure under which Silver Wheaton Corp.’s foreign subsidiaries buy and sell precious metal (silver and gold) in relation to streams on mines located outside of Canada and Silver Wheaton Corp. buys and sells silver and gold in relation to streams on mines located in Canada. In issuing the Proposal, the CRA is seeking to tax in Canada the income earned outside of Canada by our foreign subsidiaries. The Company continues to review and consider all of the implications of the Proposal and will vigorously defend its tax filing positions.

What interest and penalties may be applied by the CRA?

The Proposal indicates that the CRA is seeking to apply transfer pricing penalties of approximately Cdn$72 million (US$57 million) in respect of the Relevant Taxation Years. The CRA has not set out in the Proposal the amount of interest and penalties other than transfer pricing penalties that may apply on a notice of reassessment. Interest and penalties will only apply to the extent that the Company is required to pay reassessed tax. The Company remains confident in its business structure and tax filing positions.

What provisions of the Income Tax Act are referenced by the CRA in the Proposal?

The CRA has issued the Proposal based on the application of (i) Section 247(2) of the Income Tax Act (Canada) in respect of transfer pricing and (ii) Section 247(3) of the Income Tax Act (Canada) in respect of a transfer pricing penalty.

What are the next steps for us?

We intend to vigorously defend our tax filing positions and we are in the process of preparing our response to the Proposal. Failing a resolution at the Proposal stage, the CRA may proceed to issue notices of reassessment. We would have 90 days from the date of mailing of a notice of reassessment to file a notice of objection. Any notice of objection would be reviewed by the CRA’s Appeals Division. We would have the right to appeal directly to the Tax Court of Canada 91 days after the date of filing of any notice of objection.

Does management have a view on the outcome of responding to the Proposal or on objecting to a notice of reassessment?

Management believes that we have filed our tax returns and paid applicable taxes in compliance with Canadian tax law. We intend to vigorously defend our tax filing positions and we are in the process of preparing our response to the Proposal.

It is uncertain how long the Proposal process will take. Similarly, if the CRA issues any notices of reassessment, it is uncertain how long the CRA appeals and/or court process, if necessary, could take before ultimate resolution. The income tax provisions cited in the Proposal involve complex areas of the Income Tax Act (Canada) that have been subject to limited judicial interpretation. The application of these income tax provisions is also heavily dependent on the facts of each case. Therefore, the final outcome of any response to the Proposal and any objection to notices of reassessment resulting from the Proposal cannot be determined with any certainty, and there is, as with any appeals or court processes, risk of an unfavourable outcome. However we remain confident in our business structure and our tax filing positions.

How will this impact our ability to enter into new precious metal purchase agreements?

We do not anticipate any changes to our approach on new precious metal purchase agreements, given our confidence in our business structure and tax filing positions at this time. We believe that there continue to be strong and compelling reasons for mining companies to consider streaming transactions as an alternative source of funding and to enter into precious metal purchase agreements.

How does this Proposal impact other streaming companies in Canada?

We cannot comment on the specific manner in which other companies have structured their streaming operations. However, we believe that Silver Wheaton’s corporate structure is consistent with that typically used by Canadian companies, including Canadian streaming companies, that have international operations. With the Proposal, the CRA is seeking to tax within Canada streaming income earned outside of Canada by our foreign subsidiaries related to mines located outside of Canada.

What if we are unsuccessful in defending our tax filing positions?

We intend to vigorously defend our tax filing positions and stand behind our business structure. If we were ultimately unsuccessful in defending our filing positions, it would result in us having to pay the full amount of any reassessed tax, interest and penalties, which would have an adverse impact on our financial position.

Does management have a view on other taxation years?

The taxation years subsequent to 2010 are not under audit, however they remain open to audit by the CRA. Since the income tax provisions cited in the Proposal involve complex areas of tax law and the application of those income tax provisions is heavily dependent on the facts for each taxation year and the particular attributes of each streaming contract, we cannot speculate as to what the CRA position would be for those years. There is a risk that the CRA may take similar positions in those years as they have done in the Proposal and that such positions will result in the issuance of notices of reassessment for material amounts.

When will we provide a further update on this issue?

We believe in conservative and transparent disclosure. We anticipate providing further updates as and when we believe they are required and for certainty, we will provide further updates if and when the CRA issues one or more notices of reassessment.
