Abstract:  This paper focuses on the uniform stability of the zero solution and the asymptotic behavior of all solutions in the context of the neutral differential equation \frac{\dd}{\dd{}t}[x(t)-px(t-\tau)]+q(t)x(t-\sigma)=0\quad\text{for} t\geq{}t_0, \tag{$\star$} where $\tau,\sigma\in\R^+$, $p\in[0,1)$ and $q\in\cnt{}([t_0,\infty),\R_0^+)$. These results differ from most of the existing results in that our results extend to include values of $p\in[\frac12,1)$ for $(\star)$. Besides, the practical applicability of the given results is shown by a numerical example.
