Other current assets decreased by CHF 0.6 million as of December 31, 2022 compared to December 31, 2021 including a decrease of CHF 0.8 million in prepayments primarily due to reduced prepaid amounts related to dipraglurant clinical development activities partially offset by an increase of CHF 0.3 million in the combined amount of contract assets, trade and other receivables primarily relating to the research agreement with Indivior. The Group applies the IFRS 9 simplified approach to measuring expected credit losses (“ECL”), which uses a lifetime expected loss allowance for all contract assets, trade receivables and other receivables. As of December 31, 2022, the combined amount of the contract asset, trade receivables and other receivables amounted to CHF 0.6 million (CHF 0.3 million as of December 31, 2021) including CHF 0.4 million for the research agreement with Indivior (CHF 0.2 million as of December 31, 2021), CHF 0.1 million for the grant from Eurostars/Innosuisse (CHF 0.1 million as of December 31, 2021). The Group has considered that the contract asset, trade receivables and other receivables have a low risk of default based on historic loss rates and forward-looking information on macroeconomic factors affecting the ability of the third parties to settle invoices. As a result, expected loss allowance has been deemed as nil as of December 31, 2022, 2021 and 2020.
