Compare like-for-like

Check both observation dates before comparing yields. Reported net yields already reflect fund expenses. These funds are investments without deposit insurance; neither a displayed yield nor historical performance guarantees your return.

State tax treatment depends on annual income allocations and state rules. A Treasury portfolio label alone does not establish an exemption percentage.
