Account benefits ratio
For purposes of this section, the term “account benefits ratio” means, with respect to any fiscal year, the amount determined by the Railroad Retirement Board by dividing the fair market value of the assets in the Railroad Retirement Account and of the National Railroad Retirement Investment Trust (and for years before 2002, the Social Security Equivalent Benefits Account) as of the close of such fiscal year by the total benefits and administrative expenses paid from the Railroad Retirement Account and the National Railroad Retirement Investment Trust during such fiscal year.
