Is sei an asset manager?

Could you please clarify for me, is Sei considered an asset manager? I'm trying to understand the scope of Sei's responsibilities and whether they primarily involve managing assets for clients. Could you elaborate on Sei's role in this regard? I'm also interested in knowing if Sei offers asset management services to individuals or institutions, and if there are any specific investment strategies or asset classes that Sei specializes in. Additionally, I would like to know if Sei has any regulatory oversight or certifications that ensure the quality and integrity of their asset management services. Thank you for your assistance in clarifying this matter.
