• Transcendental meromorphic function
• deficiency

Let f be a transcendental meromorphic function in the complex plane C, and a be a nonzero complex number. We give quantitative estimates for the characteristic function T(r, f) in terms of N(r; 1/(f(l)(f((k)))(n) - a)), for integers k, l, n greater than 1. We conclude that (f(l)(f((k)))(n) assumes every nonzero finite value infinitely often.
