We include the universal part of the moduli-dependent threshold corrections in the construction of the non-perturbative effective potential due to gaugino-condensation. This allows interpolation of the magnitude of CP violating phases between the weakly and strongly coupled regimes. We find that the universal threshold corrections have a large effect on the CP violating phases in the weakly coupled regime.13 pages, LaTeX file incl. 5 EPS figs, typos correctedHigh Energy Physics - Theorytext
