The fair value of investment property was determined based on valuations performed by an independent valuation firm with appropriate professional qualifications. Under the market approach, the valuation was derived using various market data, including recent market transactions of comparable properties with

similar location, use, and scale, as well as official land prices. Under the income approach, the valuation was determined by discounting the expected future cash flows to be generated from the property using an appropriate discount rate. As significant unobservable inputs were used in these valuation processes, the fair value measurement is classified as Level 3 within the fair value hierarchy.
