In this paper, by making use of this fact that for a_j, b_j∈ℝ, j=1,2,…,n, there are λ_j∈ [0,1] with ∑_j=1^nλ_j=1 such that min_1≤ j≤ n{a_j}-min_1≤ j≤ n{b_j}=∑_j=1^nλ_j(a_j-b_j), some new error bounds of the extended vertical LCP under the row 𝒲-property are obtained, which cover the error bounds in [Math. Program., 106 (2006) 513-525] and [Comput. Optim. Appl., 42 (2009) 335-352]. Not only that, these new error bounds skillfully avoid the inconvenience caused by the row rearrangement technique for error bounds to achieve the goal of reducing the computation workload, which was introduced in the latter paper mentioned above. Besides, with respect to the row 𝒲-property, two new sufficient and necessary conditions are obtained.
