Before revision: In this paper, we complement the existing literature on the occupation time in the red (below level 0) of a spectrally negative L\'evy process, and later extend the analysis to the refracted spectrally negative L\'evy process.
After revision: In this paper, we obtain analytical expression for the distribution of the occupation time in the red (below level 0) of a spectrally negative L\'evy process, and later extend the analysis to the refracted spectrally negative L\'evy process.
