Balance in hedging reserves (income hedge) at the end of the year net (i)	-	(341,729,245)	(313,681,107)

(i) Considering the anticipated change in functional currency for Enel Generación Chile starting in 2025, these accounting hedges lose their effectiveness and, therefore, due to the change in risk management objectives, were prospectively discontinued. At the end of the 2024 fiscal year, the accumulated amount in the corresponding cash flow hedge reserves, where financial liabilities were defined as hedging instruments, amounted to ThCh $521,524,727, before taxes and minority interests. This amount was fully recognized as lower revenues for 2024 (see Notes 23.2.a, 28.1, and 41.i).
