Emulex Corp.

The Costa Mesa maker of computer components and software said Thursday that it has selected Feb. 25 as the date it will distribute stock in its QLogic Inc. unit to existing shareholders.

The tax-free transaction is contingent on shareholder approval at a Feb. 24 special meeting.

Emulex said shareholders will get one QLogic common share for each Emulex common share, pending a proposed one-for-two Emulex reverse stock split. That means someone with 100 Emulex shares would have 50 shares after the split and would receive 50 shares of QLogic stock.

Emulex will acquire all fractional shares by paying cash for each half share based on the average price of the stock for the 10 previous trading days.

Baxter Healthcare Corp.: An Irvine-based subsidiary announced Thursday that it has bought a Brazilian manufacturer of heart valves.

Baxter’s Bentley division acquired Macchi Engenharia Biomedica Ltda., based in Sao Paulo. Macchi makes blood oxygenators and mechanical heart valves and distributes pacemakers. Financial terms of the transaction were not disclosed.

Bentley also said it has signed a new four-year agreement with Haemonetics Corp. of Braintree, Mass., to continue distributing Haemonetics’ surgical blood-salvage products in the United States. The automated systems are used to collect patients’ blood before, during and after surgery for re-infusion to the patient.

Baxter Healthcare Corp. is the main unit of Baxter International Inc. in Deerfield, Ill., the world’s leading maker of health care products. Bentley makes disposable oxygenators, which provide oxygen to the blood while the heart and lungs are stopped during open-heart surgery.
