3. INVESTMENTS IN DEBT SECURITIES

Held-to-maturity debt securities are stated at amortized cost. Investments are reviewed for impairment for each reporting period. If any impairment is considered other-than-temporary, an allowance for credit loss would be established and held-to-maturity debt securities will be presented net of the credit loss allowance. Adjustments to expected credit losses are recorded as a component of other income (expense).
