Trasnferring assets

[Guest sharpie]

Are there any timing deadlines that apply when a plan is moving assets from one place to another? For example, Plan is moving all assets, lets say $1 million dollars, from insurance & annuity company A to mutual fund company B, does A have to comply within 30 or 60 or 90 days with the request? There is probably something in their contract that stipulates something, but is there anything prescribed in the regs in this regard?

Thanks
