what are the journal entries in this problem

Example Investor X holds a 10% investment in private company Y. The investment is classified as an available-for-sale investment under IAS 39. X fair values Y using a market multiple of comparable listed entity Z. Should this valuation be adjusted for: illiquidity of Y's shares, as compared to Z? the lower price X is likely to get if X sold the entire 10% investment in a single transaction rather than if it sold its shares in Y in smaller batches
