A composition comprising:
- (A) a first polymer that is a thermoplastic polyester;
- (B) a second polymer that can transesterify with said first polymer;
- (C) antimony trioxide;
- and
- (D) a thiobisphenol phosphite comprising at least one stearically hindered tris[(hydroxyphenylthio)phenyl]phosphite.

A composition that comprises a melt blend of:
- (A) from about 35 to about 55 percent by weight, based on the total weight of the composition, of poly(ethylene terephthalate) that contains antimony trioxide;
- (B) from about 20 to about 45 percent by weight, based on the total weight of the composition, of an aromatic polycarbonate;
- C) from about 15 to about 25 percent by weight, based on the total weight of the composition, of a composite interpolymer;
- (D) from about 0.5 to about 2.0 percent by weight, based on the total weight of the composition, of a thiobisphenol phosphite of the formula:
- 7
- and
- (E) optionally, up to about 1.0 percent by weight, by weight, based on the total weight of the composition, of an antioxidant that is a hindered phenol,
- wherein antimony trioxide is present in said melt blend in an amount up to about 1% by weight.
