Abstract: For a meromorphic function $ f$ in the unit disc, let the $ \rho _\infty $-order of the growth be the limit of the orders of $ L_p$-norms of $ \log \vert f(re^{i\theta })\vert$ over the circle. In the case when the order of the maximum modulus function is smaller than 1, we describe zero distribution of canonical products and derive a new factorization theorem and logarithmic derivative estimates.
