The value of my Roth IRA from a conversion that I made earlier in 2015 declined so I recharacterized part of it as a traditional IRA in September. Is there any limit on the number of partial recharacterizations I can make?

Deferred compensation

A portion of earnings withheld by an employer or put into a retirement plan for distribution to the employee at a later date. If certain legal requirements are met, the deferred amount is not taxable until actually paid, for example, after retirement.
