financial instruments question

Hi sir, I’m confused about this question

Question 108: On 1 January 20X8, Zeeper Co purchased 40,000 $1 listed equity shares at a price of $3 per share. An irrevocable election was made to recognize the shares at fair value through other comprehensive income. Transaction costs were $3,000. At the year-end of 31 December 20X8, the shares were trading at $6 per share. What amount in respect of these shares will be shown under ‘investments in equity instruments’ in the statement of financial position of Zeeper Co as at 31 December 20X8? (Enter your answer to the nearest whole $.)

Answer:
$240,000 (40,000 shares @ $6 = $240,000)

my question = Since this is FVTOCI (Fair Value Through Other Comprehensive Income), I thought that only the changes in fair value go to OCI, because that’s what the book says. But in this case, the entire new fair value ($240,000) is shown under “investments in equity instruments.”

Why is the whole fair value recognized instead of just the change in fair value? Shouldn’t only the increase from $120,000 to $240,000 ($120,000 gain) go to OCI?
