f) Cash and cash equivalents
Cash and cash equivalents represent bank deposits and liquid investments with maturities of less than three months. These amounts are stated at cost plus accrued interest, which is similar to their market value.
The Company also maintains restricted cash held as collateral to meet certain contractual obligations. Restricted cash is presented as part of “Other assets” within other non-current financial assets given that the restrictions are long-term in nature (See Note 9).
