NEWTON, Mass.--(BUSINESS WIRE)--Pro-Pharmaceuticals, Inc. (Amex: PRW), a developer of novel carbohydrate compounds, today announced it has determined that the common stock purchase warrants that were issued as part of equity finance transactions in October 2003, April 2004 and August 2004, which were accounted for in stockholders’ equity at fair value upon issuance, should have been accounted for as liabilities. The warrants, when classified as liabilities, are required to be marked to market at fair value at each reporting period, which results in a non-cash charge or credit to other income and expense in the Company’s Statement of Operations. The Company is currently quantifying the effect of the error on its financial statements. Accounting for the warrants as liabilities does not change the Company’s operating expenses or its cash position.
