That depends on the type of 457 plan, and whether you have left employment with the company (which I’m not quite sure of from reading your question). If it is a 457b plan, and you are no longer working there, then you could do a direct rollover to an IRA at Fidelity or Vanguard or T. Rowe Price. There would be no tax consequence. Once inside the IRA, you could invest in a money market mutual fund for safety.
But since there are several types of deferred comp plans be sure to check with the HR department at the company to find out your choices and the potential tax impact.
