In this paper, we introduce and investigate an interesting subclass of meromorphic bi-univalent functions defined on $\Delta = \{z\in \mathbb C : 1<|z| <\infty \}$. For functions belonging to this class, estimates on the initial coefficients are obtained. The results presented in this paper would generalize and improve some recent works of several earlier authors.
Keywords: meromorphic functions, meromorphic bi-univalent functions, coefficient estimates
