Need to Raise Additional Capital	2. Need to Raise Additional Capital We have incurred significant losses from operations since inception and expect losses to continue for the foreseeable future. As of June 30, 2015, we had cash, cash equivalents, and marketable securities of $15.7 million and working capital of $9.0 million. Our operating and capital plans call for cash expenditures to exceed these amounts over the next twelve months. We plan to raise additional capital to fund our operations and to develop our product candidates. We plan to finance our operations through partnership or licensing collaborations, the sale of equity securities or debt arrangements. Such funding may not be available or may be on terms that are not favorable to us. Our inability to raise capital as and when needed could have a negative impact on our financial condition and our ability to continue as a going concern. If we become unable to continue as a going concern, we may have to liquidate our assets, and might realize significantly less than the values at which they are carried on our financial statements, and stockholders may lose all or part of their investment in our common stock. Based on our available cash resources and our expected cash usage, we estimate that we have sufficient capital resources to meet our anticipated cash needs into the fourth quarter of 2015. Also, as discussed in Note 12, we have changed our commercial manufacturing strategy and plan to complete any required ADASUVE production under our license and supply agreements with our collaborators, Grupo Ferrer Internacional, S.A., or Ferrer, and Teva Pharmaceuticals USA, Inc., or Teva in August 2015 and then suspend commercial manufacturing at that point in time.
