In the Q1 CC, Doc explained that in addition to the .05 quarterly distribution of CCA E&P, there was further quarterly distribution of CCA E&P due to the fact that the .55 operating dividend exceeded the quarterly E&P. This was expected to total $20MM for 1999. I think that may be the piece you're missing.
Last year, a portion of the PZN regular dividend was treated as non-taxable return of capital, I believe. That was because the dividend exceeded current E&P and there was no accumulated E&P. Because of the merger, PZN now has accumulated E&P until it is all paid out, so such excess quarterly operating distributions will reduce the accumulated E&P also.
