Since she probably isn't getting an income rider on $40K, why not look at the Security Benefit Total Interest flexible premium deferred annuity? 5% first year rate, 3.00% targeted 2nd year rate (all future years are floating though, subject to a 1% GMIR).
FWIW, last year they had a 5% first year rate for awhile with a 3% target for year 2, which they ended up renewing at 2.75%.
Pays 5% w/o trail, or 4% w/ a .15% trail. 6 year surrender. You can add a Return of Premium Guarantee by taking a .10% lower interest rate (so 4.90%).
