<span style="white-space:pre-wrap; font-family: 'Times New Roman', 'serif';font-size: 10pt;font-style: normal;font-weight: normal;margin: 0;padding: 0;">USE OF ESTIMATES — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenue and expenses during the reported periods. Actual results could differ from those estimates.</span> | |
