[1] 1) The Company chose not to elect the fair value option for its financial assets and liabilities that had not been previously carried at fair value. Therefore, material financial assets and liabilities not carried at fair value, such as short-term and long-term debt obligations and trade accounts receivable and payable, are still reported at their carrying values.
