Commitments and contingencies

16. Commitments and contingencies:

The Company is a party to a variety of agreements in the ordinary course of business under which it may be obligated to indemnify third parties with respect to certain matters.  These obligations include, but are not limited to contracts entered into with physicians where the Company agrees, under certain circumstances, to indemnify a third party, against losses arising from matters including but not limited to medical malpractice and product liability.  The impact of any such future claims, if made, on future financial results is not subject to reasonable estimation because considerable uncertainty exists as to final outcome of these potential claims.
