notes to consolidated financial statements. These increases are offset in part by an $86,000 reduction in investor relations costs. Sales, general and administrative expenses were $3,553,000 and $2,876,000 for the six months ended June 30, 2006 and 2005, respectively. Sales, general and administrative expenses increased $677,000 from the six months ended June 30, 2005. This increase is attributed to a $400,000 increase in patent acquisition costs, a $440,000 increase in non-cash charges related to stock option grants to consultants and employees and a $201,000 increase in professional fees primarily resulting from costs related to the merger agreement discussed in note 1, Recent Events. These increases are offset in part by a $116,000 reduction in investor relations costs and a $332,000 reduction in OXIS expenses which are no longer consolidated with our results effective March 1, 2005 as discussed in Note 3 to the condensed consolidated financial statements. Other Income (Expense) Interest income was $625,000 and $558,000 for the quarters ending June 30, 2006 and 2005, respectively. Interest income was $1,332,000 and $1,130,000 for the six months ended June 30, 2006 and 2005, respectively. Interest income reflects the decline in cash and investment balances offset by a rise in short term interest rates. Foreign exchange losses for the quarters ended June 30, 2006 and 2005 were $32,000 and $56,000, respectively. Foreign exchange losses of $23,000 and $81,000 were incurred for the six months ended June 30, 2006 and 2005, respectively. The decline in foreign exchange losses reflects more stable exchange rates and a decline in the volume of Euro denominated transactions which reflects the completion of Phenserine trials occurring in Europe in late 2005. Gain on issuance of subsidiary stock was $78,000 net for the six months ended June 30, 2006. This gain on issuance of subsidiary stock results from common stock equity transactions in OXIS. Equity in loss of OXIS of $415,000 reflects the Company’s proportional share of OXIS losses for the six months ended June 30, 2006 under the equity method of accounting. Net Loss The Company experienced net losses of $4,183,000 ($0.08 per share-basic and diluted) and $8,179,000 ($0.15 per share-basic and diluted) for the quarters ended June 30, 2006 and 2005, respectively. The Company experienced net losses of $8,200,000 ($0.15 per share basic and diluted) and $18,612,000 ($0.35 basic and diluted) for the six months ended June 30, 2006 and 2005, respectively. The decline in loss primarily reflects reduced expenditures in 2006 due to the completion/curtailment of the Phenserine development program in late 2005. LIQUIDITY AND CAPITAL RESOURCES As of June 30, 2006 we had $50,730,000 in cash, cash equivalents and investments, and $46,624,000 in working capital. We do not have any available lines of credit. Since inception we have financed our operations from private placements of equity securities, the exercise of common stock purchase warrants, license fees, interest income and loans from a shareholder. Net cash used in operating activities for the six months ended June 30, 2006 was $7,608,000 resulting from a net loss of $8,200,000 and a decline of $2,017,000 in accounts payable. These declines are offset in part by non-cash expenses of $251,000 in depreciation and amortization, $843,000 in compensation related to options and warrants issued for services, $415,000 in equity in loss of OXIS and $274,000 in other current assets. Net cash provided by investing activities for the six month ended June 30, 2006 resulted from investment sales and maturities in excess of investment purchases. We plan to finance our needs principally from the following: |
