Highlights

Wheaton exceeded production guidance for gold,silver and palladium by 5%,9% and 41%,respectively,for the year ended December 31,2018. In addition,annual gold production and sales in 2018 represented a record for the Company.

The increase in attributable gold production for the three months and year ended December 31,2018 was primarily due to the commencement of the San Dimas gold stream effective May 10,2018,and the Stillwater precious metals stream effective July 1,as well as higher production at both Salobo and Constancia.

The decrease in attributable silver production for the three months and year ended December 31,2018 was primarily due to the termination of the San Dimas silver stream effective May 10,all deliveries from the Lagunas Norte,Veladero,and Pierina mines ceasing effective March 31,2018 in accordance with the Pascua-Lama PMPA and,for the annual period,lower production at Peñasquito due to lower throughput and planned lower grades from stockpiles during the commissioning of the now fully constructed Peñasquito Pyrite Leach Project ("PLP").

The increase in gold sales for the three months and year ended December 31,2018 was due to higher production levels,partially offset by negative changes in payable gold produced but not yet delivered to Wheaton.

The decrease in silver sales volume for the three months ended December 31,2018 was due to the lower production levels coupled with negative changes in the balance of payable silver produced but not yet delivered to Wheaton,while for the annual period,the decrease in silver sales volume was due to lower production levels,partially offset by positive changes in payable silver produced but not yet delivered.

Declared quarterly dividend of $0.09 per common share. In addition,the Company has set a minimum quarterly dividend of $0.09 per common share for the duration of 2019,subject to the discretion of the Board of Directors.

On December 13,the Company announced that it had reached a settlement with the Canada Revenue Agency (the "CRA") which provides for a final resolution of the Company's tax appeal in connection with the reassessment under transfer pricing rules of the 2005 to 2010 taxation years related to the income generated by the Company's wholly-owned foreign subsidiaries outside of Canada. After the application of non-capital losses,the settlement results in no additional cash taxes in respect of the 2005 to 2010 taxation years. The transfer pricing principles reached in the settlement will apply to taxation years after 2010,including the 2011 to 2015 taxation years which are currently under audit and on a go forward basis subject to there being no material change in facts or change in law or jurisprudence.

On October 24,Vale S.A. ("Vale") announced the approval of the Salobo III mine expansion,which would increase processing throughput capacity from 24 million tonnes per annum ("Mtpa") to 36 Mtpa once fully ramped up (the "Salobo Expansion").

Outlook

Wheaton's estimated attributable production in 2019 is forecast to be 365,000 ounces of gold,24.5 million ounces of silver and 22,000 ounces of palladium,resulting in gold equivalent production2of approximately 690,000 ounces.

For the five-year period ending in 2023,the Company estimates that average,annual gold equivalent production2will amount to 750,000 ounces.

Subsequent to the Quarter

Hudbay Minerals Inc. ("Hudbay") announced its receipt of a Section 404 Water Permit from the U.S. Army Corps of Engineers for the Rosemont Project and that it expects to receive Rosemont's Mine Plan of Operations from the U.S. Forest Service shortly.

"Wheaton had an exceptionally successful year with our precious metals business exceeding guidance for gold,silver and palladium resulting in cash flows of over $475 million," said Randy Smallwood,President and Chief Executive Officer of Wheaton Precious Metals. "In addition to our strong production and cash flow in 2018,we were also able to optimize the San Dimas stream,add two additional high-quality streams from low-cost,long-life mines and reach a settlement in our long-running tax dispute with the CRA. From the firm foundation that 2018 has provided,we expect our portfolio to now deliver steady organic growth for the foreseeable future,coming from increasing grades and better recoveries at Peñasquito,the Blitz project at Stillwater ramping up to full capacity,the development of the Pampacancha deposit at Constancia,the ongoing expansion of the Salobo mine,continued improvements at San Dimas,and now,the strong possibility of Rosemont coming into production. With our sector-leading cash flows,high margins,and steady organic growth,Wheaton is primed to be the premier investment vehicle for precious metals investors worldwide."

Financial Review

Revenues

Revenue was $197 million in the fourth quarter of 2018,on sales volume of 102,800 ounces of gold,4.4 million ounces of silver and 5,000 ounces of palladium. This represents a 19% decrease from the $243 million of revenue generated in the fourth quarter of 2017 due primarily to (i) a 40% decrease in the number of silver ounces sold; (ii) a 12% decrease in the average realized silver price ($14.66 in Q4 2018 compared with $16.75 in Q4 2017); and (iii) a 4% decrease in the average realized gold price ($1,229 in Q4 2018 compared with $1,277 in Q4 2017); partially offset by (iv) a 9% increase in the numberof gold ounces sold; and (v) the introduction of palladiumsales effective Q3 2018.

Revenue was $794 million in the year ended December 31,on sales volume of 349,200 ounces of gold and 21.7 million ounces of silver. This represents a 6% decrease from the $843 million of revenue generated in 2017 due primarily to (i) a 12% decrease in the number of silver ounces sold and; (ii) a 7% decrease in the average realized silver price ($15.81 in 2018 compared with $17.01 in 2017); partially offset by (iii) a 4% increase in the number of gold ounces sold; and (iv) the introduction of palladium sales effective Q3 2018.

Costs and Expenses

Average cash costs¹ in the fourth quarter of 2018 were $409 per gold ounce sold,$4.66 per silver ounce sold and $205 per palladium ounce sold,as compared with $399 per gold ounce and $4.48 per silver ounce during the comparable period of 2017. This resulted in a cash operating margin¹ of $820 per gold ounce sold,$10.00 per silver ounce sold and $932 per palladium ounce sold,a reduction of 7% and 19% for gold and silver,as compared with Q4 2017. The decrease in the cash operating margin was primarily due to a 4% decrease in the average realized gold price and a 12% decrease in the averagerealized silver price in Q4 2018 compared with Q4 2017.

Average cash costs¹ during the year ended December 31,2018 were $409 per gold ounce sold,$4.67 per silver ounce sold and $190 per palladium ounce sold,as compared with $395 per gold ounce sold and $4.49 per silver ounce sold during the comparable period of 2017. This resulted in a cash operating margin¹ of $855 per gold ounce sold,$11.14 per silver ounce sold and $870 per palladium ounce sold,a reduction of 1% and 11% for gold and silver,as compared with 2017. The decrease in the cash operating margin for silver was primarily due to a 7% decrease in the average realized silver price in 2018 compared with 2017.

Earnings and Operating Cash Flows

Adjusted net earnings¹ and cash flow from operations in the fourth quarter of 2018 were $37 million ($0.08 per share) and $108 million ($0.24 per share¹),compared with adjusted net earnings¹ of $82 million ($0.19 per share) and cash flow from operations of $165 million ($0.37 per share¹) for the same period in 2017,a decrease of 55% and 34%,respectively.

Adjusted net earnings¹ and cash flow from operations for the year ended December 31,2018 were $214 million ($0.48 per share) and $477 million ($1.08 per share¹),compared with adjusted net earnings¹ of $277 million ($0.63 per share) and cash flow from operations of $539 million ($1.22 per share¹) for the same period in 2017,a decrease of 23% and 11%,respectively.

Balance Sheet

At December 31,the Company had approximately $76 million of cash on hand and $1.3 billion outstanding under the Company's $2 billion revolving term loan (the "Revolving Facility").On February 27,2019,the term of the Revolving Facility was extended by an additional year,with the facility now maturing on February 27,2024.

Tax Dispute Settlement

On December 13,the Company reached a settlement with the CRA which provides for a final resolution of Wheaton's tax appeal in connection with the reassessment of the 2005 to 2010 taxation years under transfer pricing rules related to income generated by the Company's foreign subsidiaries outside of Canada. The terms of the settlement provide that foreign income on earnings generated by Wheaton's wholly-owned foreign subsidiaries will not be subject to tax in Canada. The transfer pricing principles reached in the settlement will apply to taxation years after 2010,including the 2011 to 2015 taxation years which are currently under audit and on a go forward basis subject to there being no material change in facts or change in law or jurisprudence. In addition,the settlement provided that the service fee charged by the Company for the services rendered to its foreign subsidiaries will be adjusted by,first,including the capital-raising costs incurred by the Company for the purpose of funding precious metals purchase agreements entered into by the Company's foreign subsidiaries and secondly,increasing the markup on costs incurred by the Company that are charged to the foreign subsidiaries,including attributable capital-raising costs,from 20% to 30%.

The CRA Settlement resulted in total expenses of $29 million in respect of the 2005-2017 taxation years being reflected in the Statement of Earnings during the fourth quarter,including a non-cash income tax expense of $16 million,for a net cash expense of $13 million comprised of (i) $4 million of current income taxes; (ii) $4 million of interest and penalties; and (iii) $5 million of professional fees.

Fourth Quarter Asset Highlights

During the fourth quarter of 2018,attributable production was 107,600 ounces of gold,5.5 million ounces of silver and 5,900 ounces of palladium,representing an increase of 11% and a decrease of 23% for gold and silver,as compared with the fourth quarter of 2017.

Operational highlights for the quarter ended December 31,based upon counterparties' reporting,are as follows:

Salobo

In the fourth quarter of 2018,Salobo produced 77,000 ounces of attributable gold,an increase of approximately 1% relative to the fourth quarter of 2017. As per Vale's third quarter 2018 MD&A,on October 24,Vale's Board of Directors approved the Salobo Expansion,a brownfield expansion,which if completed as proposed,would increase processing throughput capacity to 36 Mtpa. Wheaton Precious Metals International Ltd. ("Wheaton International") first entered into a gold purchase agreement with Vale in respect of the Salobo mine in 2013 and made subsequent amendments to the agreement in 2015 and 2016 (the "Gold Agreement"). As part of the Gold Agreement,if actual throughput is expanded above 28 Mtpa within a predetermined period,and depending on the grade of material processed,Wheaton will be required to make an additional payment to Vale based on a set fee schedule. As proposed,the Salobo Expansion would increase throughput capacity from 24 Mtpa to 36 Mtpa once fully ramped up. Vale has approved the investment of US$1.1 billion in the Salobo Expansion,with a start-up scheduled for the first half of 2022 and an estimated ramp-up of 15 months. Vale has indicated that the Salobo Expansion will encompass a third concentrator and will use Salobo's existing infrastructure. As agreed to as part of the original Gold Agreement and based on Vale's disclosure relating to size and timing of the Salobo Expansion,the Company estimates that an expansion payment of between $550 million to $650 million would be payable. Given Vale's proposed schedule,this payment would likely be made no earlier than 2023.

Peñasquito

In the fourth quarter of 2018,Peñasquito produced 1.5 million ounces of attributable silver,a decrease of approximately 7% relative to the fourth quarter of 2017 due to lower throughput. According to Goldcorp Inc.'s fourth quarter of 2018 MD&A,higher than expected ore hardness impacted mill throughput in the quarter. In addition,commissioning of the PLP continued during the quarter,with the project having achieved commercial production as of December 31,2018. The Carbon Pre-flotation Plant,a component of the PLP,achieved commercial production on October 1,and was successfully treating high-carbon ore during the fourth quarter of 2018.

Antamina

In the fourth quarter of 2018,Antamina produced 1.2 million ounces of attributable silver,a decrease of approximately 15% relative to the fourth quarter of 2017 as expected due to mine sequencing in the open pit.

San Dimas

In the fourth quarter of 2018,San Dimas produced 10,100 ounces of attributable gold. According to First Majestic Silver Corp.'s ("First Majestic") fourth quarter of 2018 production report,the San Dimas mill processed a total of 172,641 tonnes with average gold and silver grades of 3.9 g/t and 262 g/t,respectively. The operation reportedly continued to process higher volumes from lower grade stopes left behind as they were deemed uneconomical under the old streaming agreement and have now become economical under the new streaming agreement.

Sudbury

In the fourth quarter of 2018,Vale's Sudbury mines produced 7,100 ounces of attributable gold,a decrease of approximately 18% relative to the fourth quarter of 2017 primarily due to lower throughput and grades.

Constancia

In the fourth quarter of 2018,Constancia produced 4,300 ounces of attributable gold and 0.7 million ounces of attributable silver,an increase of approximately 45% and 12%,relative to the fourth quarter of 2017 due to higher precious metals grades and recovery.

Stillwater

In the fourth quarter of 2018,the Stillwater mines produced 3,500 ounces of attributable gold and 5,900 ounces of attributable palladium. On July 25,the Company,through its wholly owned subsidiary Wheaton International,completed the acquisition from Sibanye-Stillwater of a fixed percentage of gold and palladium production from the Stillwater mines. As part of the agreement,Wheaton International was entitled to the attributable gold and palladium production for which an offtaker payment was received after July 1,resulting in reported production for the third quarter including some material processed in the previous quarters. As a result,the Stillwater mines significantly outperformed the Company's expectations in the first six months of the stream,with attributable production of 9,800 ounces of attributable gold and 14,700 ounces of attributable palladium relative to 2018 guidance of approximately 5,400 ounces of gold and 10,400 ounces of palladium.

Other Gold

In the fourth quarter of 2018,total Other Gold attributable production was 5,700 ounces,a decrease of approximately 35% relative to the fourth quarter of 2017. The decrease was due primarily to lower production at the Minto mine. As per Capstone Mining Corp.'s ("Capstone") news release dated October 11,the agreement under which Capstone had agreed to sell its Minto mine to Pembridge Resources plc has been terminated. In conjunction with this,Capstone placed the Minto mine on care and maintenance in the fourth quarter of 2018.

Other Silver

In the fourth quarter of 2018,total Other Silver attributable production was 2.1 million ounces,a decrease of approximately 3% relative to the fourth quarter of 2017. The slight decrease was driven primarily by the cessation of attributable production from the Lagunas Norte,Veladero and Pierina mines as the silver purchase agreement with Barrick Gold Corp. ("Barrick") related to these mines expired on March 31,and lower production at Yauliyacu,partially offset by the start-up of attributable production at the Aljustrel mine.

Produced But Not Yet Delivered 3

As at December 31,payable ounces attributable to the Company produced but not yet delivered amounted to 77,500 payable gold ounces,3.3 million payable silver ounces and 5,300 payable palladium ounces,representing a decrease of 100 payable gold ounces,an increase of 0.2 million payable silver ounces and an increase of 600 payable palladium ounces during the three month period ended December 31,2018. Payable gold ounces produced but not yet delivered decreased slightly primarily as a result of decreases related to the Salobo and Other gold interests partially offset by increases related to the San Dimas and Sudbury gold interests. Payable silver ounces produced but not yet delivered increased primarily as a result of increases related to the Peñasquito partially offset by a decrease related to the Antamina silver interest. Payable ounces produced but not yet delivered to the Wheaton group of companies are expected to average approximately two to three months of annualized productionfor both gold and palladium and two months for silver but may vary from quarter to quarter due to a number of mining operation factors including mine ramp-up and timing of shipments.

Detailed mine-by-mine production and sales figures can be found in the Appendix to this press release and in Wheaton's consolidated MD&A in the 'Results of Operations and Operational Review' section.

Subsequent to the Quarter

Rosemont

Hudbay announced its receipt of a Section 404 Water Permit from the U.S. Army Corps of Engineers. Hudbay has indicated that it expects to receive Rosemont's Mine Plan of Operations from the U.S. Forest Service shortly.

As a reminder,Wheaton's wholly owned subsidiary Wheaton International has a precious metals purchase agreement with Hudbay on Rosemont,which in exchange for an upfront payment of $230 million,entitles the Company to 100% of payable gold and silver produced from Rosemont at a cash price of $450 per ounce of gold and $3.90 per ounce of silver,subject to an annual adjustment for inflation. In February 2019,Wheaton International amended the Rosemont PMPA with Hudbay. As a result of the amendment and given that all material permits have now been received,Wheaton International is committed to pay Hudbay the upfront payment in two instalments,with the first $50 million being advanced upon the request of Hudbay conditional on Hudbay demonstrating that it has sufficient capital to complete construction of Rosemont,development and construction of Rosemont having commenced and other customary conditions. The balance of $180 million will be advanced following a request by Hudbay,conditional on project costs of at least $98 million having been incurred on the Rosemont project and other customary conditions. Additionally,under the terms of the amendment,Hudbay has provided a corporate guarantee and Wheaton International will be entitled to certain delay payments,including where construction ceases in any material respect or if the completion test is not achieved within agreed upon timelines.

Reserves and Resources

As of December 31,Proven and Probable Mineral Reserves attributable to Wheaton were 11.75 million ounces of gold compared with 11.28 million ounces as reported in Wheaton's 2017 Annual Information Form ("AIF"),an increase of 4%,542.1 million ounces of silver compared with 575.2 million ounces,a decrease of 6%,0.66 million ounces of palladium and 32.6 million pounds of cobalt. On an attributable Measured and Indicated Mineral Resource basis,gold resources were 2.89 million ounces compared with 2.67 million ounces as reported in Wheaton's 2017 AIF,an increase of 8%,silver resources were 784.4 million ounces compared with 887.0 million ounces,a decrease of 12%,and 1.6 million pounds of cobalt. On an attributable Inferred Mineral Resource basis,gold resources were 4.08 million ounces compared with 2.71 million ounces as reported in Wheaton's 2017 AIF,an increase of 50%,silver resources were 432.7 million ounces compared with 446.5 million ounces,a decrease of 3%,0.36 million ounces of palladium and 9.3 million pounds of cobalt.

Estimated attributable reserves and resources contained in this press release are based on information available to the Company as of March 20,and therefore will not reflect updates,if any,after that date. Updated reserves and resources data incorporating year-end 2018 estimates will also be included in the Company's 2018 Annual Information Form. Wheaton's most current attributable reserves and resources,as of December 31,can be found on the Company's website at www.wheatonpm.com.

Outlook

Wheaton's estimated attributable precious metals production in 2019 is forecast to be approximately 365,000 ounces. For the five-year period ending in 2023,the Company estimates that average annual gold equivalent production2will amount to 750,000 ounces.

In 2019,forecast silver production growth from Peñasquito is expected to be partially offset by the change in the San Dimas stream from silver to gold as well as the cessation in 2018 of production from assets with fixed terms. Gold production in 2019 is expected to be slightly below 2018 as a result of lower grades at Salobo due to mine sequencing (most pronounced in the first quarter of 2019) being partially offset by increased attributable gold production from the San Dimas mine. At Constancia,Hudbay expects to begin mining the Pampacancha satellite deposit later in 2019,which has significantly higher precious metals grades than what is currently being mined; however,given the lack of a definitive schedule at this point,forecast gold production in 2019 does not include any contribution from the Pampacancha deposit4. Palladium production is expected to increase in 2019 as the Company has its first full year of production from the Stillwater stream,which was acquired in July of 2018.

Average production over the next five years is expected to increase primarily due to continued production growth from Peñasquito,Constancia and Stillwater as well as the commencement of the Voisey's Bay stream in 2021. At Peñasquito,grades are expected to increase and the addition of the PLP should improve recoveries. At Constancia,production from the Pampacancha deposit is included in Wheaton's five-year production average. Palladium and gold production from Stillwater is expected to increase with the continued ramp-up of the Blitz project,which is expected to reach full capacity in 2021. In addition,effective January 1,2021,Wheaton will be entitled to receive from Vale an amount of cobalt equal to 42.4% of the Voisey's Bay mine cobalt production. And lastly,Wheaton does not include any production from Barrick's Pascua-Lama project or Hudbay's Rosemont project in its estimated average five-year production guidance5.

From a liquidity perspective,the $76 million of cash and cash equivalents as at December 31,2018 combined with the liquidity provided by the available credit under the $2 billion Revolving Facility and ongoing operating cash flows positions the Company well to fund all outstanding commitments and known contingencies as well as providing flexibility to acquire additional accretive precious metal stream interests.

End Notes

____________________

1Please refer to non-IFRS measures at the end of this press release. Dividends declared in the referenced calendar quarter,relative to the financial results of the prior quarter.

2 Gold equivalent ounces for 2018 actual production and sales are calculated by converting silver to a gold equivalent by using the ratio of the average price of silver to the average price of gold and by converting palladium to a gold equivalent by using the average price of palladium to the average price of gold,with all figures being as per the London Bullion Metal Exchange during 2018. Gold equivalent production forecasts for 2018,2019 and the five-year average are based on the following commodity price assumptions: $1,300 / ounce gold,$16 / ounce silver,$1,350 / ounce palladium,and $21 / pound of cobalt.

3Payable gold,silver and palladium ounces produced but not yet delivered are based on management estimates and may be updated in future periods as additional information is received.

4As per Wheaton's precious metals purchase agreement with Hudbay,Wheaton is entitled to a delay payment payable in gold ounces from Hudbay as a result of the delay in mining the Pampacancha zone. The gold ounces delivered to Wheaton are included in the Company's production guidance.

5In preparing the long-term production forecast,Wheaton has considered the impact of Vale's recently announced approval of the Salobo III copper project,would increase processing throughput capacity from 24 Mtpa to 36 Mtpa once fully ramped up (the "Salobo Expansion"). However,readers are cautioned that Vale has not finalized its mine plan and as such,Wheaton has not included any production growth as a result of the Salobo Expansion.

Non-IFRS Measures

Wheaton Precious Metals has included,throughout this document,certain non-IFRS performance measures,including (i) adjusted net earnings and adjusted net earnings per share; (ii) operating cash flow per share (basic and diluted); (iii) average cash costs of gold,silver and palladium on a per ounce basis and; (iv) cash operating margin.

Adjusted net earnings and adjusted net earnings per share are calculated by removing the effects of the non-cash impairment charges,non-cash fair value (gains) losses,non-cash share of losses of associates and other one-time (income) expenses. The Company believes that,in addition to conventional measures prepared in accordance with IFRS,management and certain investors use this information to evaluate the Company's performance.

The following table provides a reconciliation of adjusted net earnings and adjusted net earnings per share (basic and diluted).

Cautionary Language Regarding Reserves And Resources

For further information on Mineral Reserves and Mineral Resources and on Wheaton more generally,readers should refer to Wheaton's Annual Information Form for the year ended December 31,2017 and other continuous disclosure documents filed by Wheaton since January 1,available on SEDAR at www.sedar.com. Wheaton's Mineral Reserves and Mineral Resources are subject to the qualifications and notes set forth therein. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability.

Cautionary Note to United States Investors Concerning Estimates of Measured,Indicated and Inferred Resources:The information contained herein has been prepared in accordance with the requirements of the securities laws in effect in Canada,which differ from the requirements of United States securities laws. The terms "mineral reserve","proven mineral reserve" and "probable mineral reserve" are Canadian mining terms defined in accordance with Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining,Metallurgy and Petroleum (the "CIM") – CIM Definition Standards on Mineral Resources and Mineral Reserves,adopted by the CIM Council,as amended (the "CIM Standards"). These definitions differ from the definitions in Industry Guide 7 ("SEC Industry Guide 7") under the U.S. Securities Act of 1933,as amended (the "U.S. Securities Act"). Under U.S. standards,mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Also,under SEC Industry Guide 7 standards,a "final" or "bankable" feasibility study is required to report reserves,the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. In addition,the terms "mineral resource","measured mineral resource","indicated mineral resource" and "inferred mineral resource" are defined in and required to be disclosed by NI 43-101; however,these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. "Inferred mineral resources" have a great amount of uncertainty as to their existence and as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules,estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies,except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however,the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures. Accordingly,information contained herein that describes Wheaton's mineral deposits may not be comparable to similar information made public by U.S. companies subject to reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder. United States investors are urged to consider closely the disclosure in Wheaton's Form 40-F,a copy of which may be obtained from Wheaton or from http://www.sec.gov/edgar.shtml.

In accordance with the Company's MD&A and financial statements,reference to the Company includes the Company's wholly owned subsidiaries.
