Hello Everyone,
Risk on securities depends on both operating as well financing risk of business which are respectively measures by DOL & DFL.
As DFL measures the senstivity of future CF to owners or net income due to change in operating income.This risk is orginates due to choice of capital structure.
As operating income does not includes fixed interest expense to debt holders whuch affect the NI not operating income.
As per my understanding then this senstivity has to be towards fixed interest expense rather than operating income which is affected by fixed production cost .
THANKS
