Abstract: We present detailed radiative transfer spectral synthesis models for the IronLow Ionization Broad Absorption Line FeLoBAL active galactic nuclei AGNFIRST J121442.3+280329 and ISO J005645.1-273816. Detailed NLTE spectralsynthesis with a spherically symmetric outflow reproduces the observed spectravery well across a large wavelength range. While exact spherical symmetry isprobably not required, our model fits are of high quality and thus very largecovering fractions are strongly implied by our results. We constrain thekinetic energy and mass in the ejecta and discuss their implications on theaccretion rate. Our results support the idea that FeLoBALs may be anevolutionary stage in the development of more ``ordinary- QSOs.
