Convertion of 403(a) Plan

[Guest Tom:]

Can I convert our 403(a) annuity plan to a 401(a) plan by liquidating the annuity contract and depositing the proceeds in a 501(a) trust? I would prefer to do this without obtaining participant elections or rollovers. The 403(a) plan contains only nonelective employer contributions and has been administered in accordance with the profit sharing plan requirements applicable under 404(a)(2). Are there any particular issues or traps I need to aware of under the Code or ERISA?
