Restricted cash is held on account with a financial institution in Canada to support a Letter of Guarantee issued in Canada and counter-guaranteed by the financial institution's Athens branch. The Letter of Guarantee was issued pursuant to the request from the Ministry of Environment and Energy in Greece to support the operation and restoration of the Kokkinolakkas Tailings Management Facility. The funds are invested at prevailing bank rates and interest is accrued monthly. Interest is paid directly to the account with the total balance being recorded as restricted cash. The account allows for any excess, above the notional principal of the Letter of Guarantee, to be remitted back to the Company.
