Standard&Poor's said today that the completion of the conversion of PetsMart Inc.'s (B+/Stable/--) $172.5 million convertible subordinated notes into common equity has no impact on its credit rating or outlook. The notes were scheduled to mature in November 2004. Although the conversion improves the company's capital structure somewhat, and other credit measures have also benefited from recent improvement in operating performance, PetsMart needs to demonstrate a more sustainable improvement in its operations before a change in its credit profile is considered.
