We discuss the asymptotic behaviour of all solutions of the functional differential equation y ' ( x ) = i = 1 m a i ( x ) y ( τ i ( x ) ) + b ( x ) y ( x ) , where b ( x ) < 0 . The asymptotic bounds are given in terms of a solution of the functional nondifferential equation i = 1 m | a i ( x ) | ω ( τ i ( x ) ) + b ( x ) ω ( x ) = 0 .
