What is Funding cost and benefit adjustments?

The funding cost adjustment is $\mathrm{FCA} = \int_0^Ts_f(t)\,\mathrm{DEE}(t)\,Q_C(t)Q_B(t)\,dt$, the funding spread $s_f$ paid on the discounted expected positive exposure while both parties survive; the funding benefit adjustment FBA is the same integral on the discounted expected negative exposure, at the rate the bank saves.
