To the extent there are differences between these estimates, judgments or assumptions and the actual results, our consolidated financial statements will be affected. In many cases, the accounting treatment of a particular transaction is specifically dictated by US GAAP and does not require management’s judgment in its application. There are also areas in which management’s judgment in selecting from available alternatives would not produce a materially different result.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Our most critical accounting estimates include: </p> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">-</td><td style="text-align: justify">Inventory Valuation (see Note 10)</td></tr></table> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"></p> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">-</td><td style="text-align: justify">Recoverability of deferred tax assets (see Note 30)</td></tr></table> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"></p> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">-</td><td style="text-align: justify">Revenue recognition (see Note 25)</td></tr></table> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"></p> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">-</td><td style="text-align: justify">Bonds, mortgages and other long-term debt (see Note 19)</td></tr></table> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"></p> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">-</td><td style="text-align: justify">Convertible note payable, noncurrent (see Note 19)</td></tr></table> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"></p> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">-</td><td style="text-align: justify">Indebtedness to related parties (see Note 20)</td></tr></table> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"> </p>
