401k Catch-up
A 401k catch-up contribution is any elective deferral made by an eligible participant that is in excess of the statutory limit of $17,000 in a given year. The 2012 401k catch-up maximum is $5,500 per year and will continue to be indexed for inflation in upcoming years. Although to be eligible for a 401k catch-up contribution there are a few stipulations. First, you must be or be turning 50 years of age during the calendar year and second you must reach at least one of the following limits before catch-up contributions can begin:

a. Annual deferral limit

b. Plans deferral limit

c. Annual ADP limit for highly compensated employees.

According to the Profit Sharing & 401k Council of America, 98% of all employer sponsored retirement plans permit catch-up contributions, but only 31% of employers match 401k catch-up contributions.
