Abstract
Let $(X,\Delta)$ be a normal pair with a projective morphism $X \to Z$ and let $A$ be a relatively ample $\mathbb{R}$-divisor on $X$. We establish the minimal model theory for $(X,\Delta+A)/Z$ under assumptions that the non-nef locus of $K_{X}+\Delta+A$ over $Z$ does not intersect the non-lc locus of $(X,\Delta)$ and that the restriction of $K_{X}+\Delta+A$ to the non-lc locus of $(X,\Delta)$ is semi-ample over $Z$.
