Abstract: We prove a relation between a certain weighted radial limit of an $ n$-subharmonic function in the polydisc $ {U^n}$ and the representing measure of its least $ n$-harmonic majorant. We apply this result to functions in $ N({U^n})$, the Nevalinna class of $ {U^n}$. In particular, we obtain a necessary condition for a function to belong to the component of the origin in $ N({U^n})$. These results are extensions of the work of J. H. Shapiro and A. L. Shields to $ n > 1$.
