Derecognition of financial asset: transfer and control tests determine derecognition and profit or loss recognition on disposal. Derecognition arises when rights to cash flows expire, are transferred with substantially all risks and rewards, or when neither risks nor control are retained. Partial derecognition applies to specifically identified cash flows, pro rata shares, or pro rata identified cash flows. Pass-through transfers qualify as transfers only if the transferor has no obligation beyond collected amounts, cannot sell or pledge the original asset except as security to eventual recipients, and must remit collections without material delay. Servicing rights retained on a transfer that qualifies for derecognition are recognised as servicing assets or liabilities at fair value, and any new financial assets or liabilities obtained are measured at fair value. The gain or loss equals the carrying amount allocated to the derecognised part minus the consideration received.
