Let \(k\) be a positive integer and let \(w(z)\) be a meromorphic function defined on \(\mathbb{C}\) of lower order \(\lambda < \infty\). Let \(\{a_\nu\}\) be a finite set of distinct complex numbers. Then it is possible to find positive numbers \(r_n \to \infty\) such that \[ \sum^q_{\nu = 1} r_n \int_{|w (r_n e^{i \theta}) - a_\nu |< 1} \biggl |\log^{(k)} \bigl( w(r_ne^{i \theta}) - a_\nu \bigr) \biggr |^{1/k} d \theta \leq K (k, \lambda) T(r_n). \] The proof uses ``The closeness property of \(a\)-points'' [the first author, Mat. Sb. 120(162), No. 1, 42-67 (1983; Zbl 0509.30021)].
