Regarding Required Minimum Distribution (RMD), IRS Pub. 590-B says:
"Annuity distributions from an insurance company: Special rules apply if you receive distributions from traditional IRA as an annuity purchased from an insurance company. See Regulatons sections 1.401(a)(9)-6 and 54.4974-2."
However, I could not find any life expectancy or distribution period tables such as those found in Pub. 590-B. How do I calculate my RMD in this case?

Appendix B of IRS Publication 590-B contains the life expectancy table needed to calculate RMDs. So, you may determine your distribution period / life expectancy by using the Tables in Appendix B of Publication 590-B Distributions from IRAs.Table I ? for beneficiaries:Table II ? for owners whose spouse is 10 years younger and the IRA?s sole beneficiary:Table III ? for all other owners (most IRA owners will use this table)
Please contact the plan admin for more accurate info in detail. sorry I m not a plan expert.

Thanks.

Yes, I know about the Tables in 590-B. What I was asking was, how do I calculate the RMD for annuities. So, I guess what you're saying is to contact the plan administrator.
