CYA
Simplify Tail Risk Strategy ETF
stock NYSE

FDLXX is typically 98-99% CA state tax free.
FCTFX is managed to essentially be 100% CA state tax free but uses 80% as a CYA in its prospectus.
The TSP is a tax deferred plan so there is no state tax benefit by holding the G fund.

Seems like a CYA move to me. Later they can point back to it and say, "Well, we did warn you."

IYKYK, ASAP, CYA, IANAL, NFA, NGL.
