It also requires the use of accounting estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the Consolidated Financial Statements, disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements, and reported amounts of revenues and expenses during the reporting periods. Although these estimates are based on management's best knowledge of current events and actions, actual results may ultimately differ from those estimates.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%">Critical estimates and judgements made by management relate to:</span></div><div style="padding-left:18pt;text-align:justify;text-indent:-18pt"><span style="background-color:#ffffff;color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:13.5pt">Deferred income taxes (Note 6);</span></div><div style="padding-left:18pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%">•</span><span style="background-color:#ffffff;color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:13.5pt">Business acquisitions </span><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%">(Note 11);</span></div><div style="padding-left:18pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:13.5pt">Properties (Note 13);</span></div><div style="padding-left:18pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:13.5pt">Goodwill (Note 14);</span></div><div style="padding-left:18pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:13.5pt">Intangible assets (Note 15);</span></div><div style="padding-left:18pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:13.5pt">Provision for environmental remediation (Note 19);</span></div><div style="padding-left:18pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:13.5pt">Pension and other benefits (Note 23); and</span></div><div style="padding-left:18pt;text-align:justify;text-indent:-18pt"><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Frutiger LT Com 47 Light Cn',sans-serif;font-size:9pt;font-weight:400;line-height:120%;padding-left:13.5pt">Legal claims (Note 26).</span></div>
