[1] On 24 February 2022 the Russian Federation launched a full-scale military invasion into Ukraine. This has already led to significant economic and humanitarian consequences for both countries, and the long-term wider impact continues to be unknown as the situation develops. Areas of uncertainty include the impact on global energy prices, financial markets as well as the possible further escalation of the conflict (note 35). Consequently, the fair value of the bond decreased to USD 918 thousand and its credit rating was downgraded from BBB as at 31 December 2021 to B in March 2022.
