4.3.21Net Cash and Cash Equivalents

The decrease of the Cash and bank balances mainly relates to the significant progress in the projects under construction and the related use of cash from the financing facilities secured in 2021, partially covered by the additional project financing granted for FPSO ONE GUYANA and the cash generated by Lease and Operate business segment.

The cash and cash equivalents dedicated to debt and interest payments (and therefore restricted) amounted to US$235 million as per December 31, 2022 (2021: US$152 million). Short-term investment deposits are made for varying periods of up to one year, usually less than three months, depending on the immediate cash requirements of the Company, and earn interest at the respective short-term deposit rates.

The cash and cash equivalents held in countries with restrictions on currency outflow (Angola, Brazil, Equatorial Guinea, Ghana and Nigeria) amounted to US$21 million (2021: US$23 million). These restrictions do not limit the liquidity of the cash balances.
