PDX PIMCO Dynamic Income Strategy Fund

Pediatrix Medical Group, Inc., (NYSE:PDX) today announced that it is revising its earnings guidance for the three months ended June 30, 2008, and for the full year based on lower neonatal intensive care unit patient volume. During the Company�s 2008 first quarter earnings call, Pediatrix mentioned that same-unit NICU volume for April 2008 was below 2007 levels. Through the first six weeks of the 2008 second quarter Pediatrix�s same-unit NICU volume declined by approximately 2 percent when compared to the same period of 2007. Pediatrix now expects to earn 77 cents to 80 cents for the 2008 second quarter if NICU patient volume remains at current levels for the rest of the period. In addition, at this time Pediatrix does not expect to meet its previously issued earnings guidance for the 12 months ended December 31, 2008, as a result of lower NICU patient volume during 2008 to date. Pediatrix�s earnings guidance is based on assumptions for same-unit growth from patient volume and reimbursement, as well as contributions from acquisitions. Pediatrix�s ability to achieve its previously issued earnings guidance for the 2008 third and fourth quarters will be based on NICU patient volume growth reverting to historical levels of 3 to 5 percent. Pediatrix expects that it will update its guidance for the second half of 2008 when it issues its 2008 second quarter results and that it will discuss guidance during the related quarterly earnings conference call. Separately, Pediatrix�s Board of Directors has authorized the Company to repurchase up to $100 million of its common stock through open market transactions. The share repurchase program is effective immediately and permits the Company to make open market purchases from time-to-time based on price, general market and economic conditions as well as trading restrictions.
