Marketable Securities

I would appreciate if somebody with strong accounting background could confirm these : Unrealized gains/losses from trading securities go to the operating section of the Income statement. They go to CFO when realized. Unrealized gains/losses from available for sale securities go to Other Comprehensive Income. They go to CFI when realized. Unrealized gains/losses from held to maturity securities go to nonoperating section of the Income Statement. They go to CFI when realized. Thanks!

the above is correct
