How often does Janus Henderson pay dividends?

I'm curious to know about the dividend policy of Janus Henderson. Could you elaborate on how frequently they tend to pay dividends to their shareholders? I understand that this could vary based on their performance and earnings, but is there a general trend or pattern in their dividend payments that investors can rely on? Is it a quarterly, semi-annual, or annual dividend payment structure? I'd appreciate any insight you could provide regarding Janus Henderson's dividend schedule and payment habits.
