## Abstract

Let *f* be transcendental and meromorphic in the plane of finite lower order with a bounded set of finite critical and asymptotic values. It is shown that a rational deficient function of any derivative of *f* is zero at infinity. If instead *f* has arbitrary order and a finite set of critical and asymptotic values, then any rational deficient function of *f*' must have a multiple zero at infinity. Furthermore, if such *f* has finite lower order then *f*' admits no rational deficient functions other than 0.
