March

2017,

we had

$126.3

million of cash and cash equivalents, a decrease of

$12.6

million from

$138.9

million at

December

31,

2016.

We expect that this amount will be sufficient to fund operations as currently anticipated beyond

one

year from the filing date of this Form

-Q. We have historically funded our operations to a significant extent from capital-raising and we expect to require additional funding in the future, the availability of which is never guaranteed and

may

be uncertain. We expect that we

may

continue to incur operating losses for the foreseeable future.

Basis of Accounting, Policy [Policy Text Block]

Basis of Presentation

Our interim condensed consolidated financial statements have been prepared in accordance with applicable presentation requirements, and accordingly, do not include all information and disclosures necessary for a presentation of our financial position, results of operations, and cash flows in conformity with accounting principles generally accepted in the U.S. ("GAAP"). In the opinion of management, these financial statements reflect all adjustments, consisting primarily of normal recurring accruals necessary for a fair statement of results for the periods presented. The results of operations for interim periods are not necessarily indicative of the results for the full year.

Our interim condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto contained in our Annual Report on Form

-K for the year ended

December

31,

2016.

The year-end consolidated balance sheet data in these financial statements were derived from audited financial statements but do not include all disclosures required by GAAP. Certain prior period amounts in our condensed consolidated financial statements have been reclassified to conform to the current period presentation. Accounts payable, which was historically combined with accrued expenses on our consolidated balance sheet, has been presented as a separate line item for all periods presented in these unaudited condensed consolidated financial statements.

Consolidation, Policy [Policy Text Block]

Principles of Consolidation

The condensed consolidated financial statements include the accounts of Progenics as well as its wholly-owned subsidiaries. All material intercompany transactions and balances have been eliminated in consolidation.

December

2015,

we commenced a judicial process in Sweden for acquiring the remaining shares of EXINI. On

December

2016,

a Swedish arbitral tribunal awarded us advanced title to the remaining shares of EXINI and, as of that date, EXINI became a wholly-owned subsidiary with

100%

of the voting shares owned by us. We paid

$368

thousand to the minority interest shareholders in connection with the acquisition of the remaining shares of EXINI.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results

may

differ from those estimates.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign Currency Translation

Each of our international subsidiaries generally considers their respective local currency to be their functional currency. Assets and liabilities of these international subsidiaries are translated into U.S. dollars at quarter-end exchange rates and revenues and expenses are translated at average exchange rates during the quarter and year-to-date period. Foreign currency translation adjustments for the reported periods are included in accumulated other comprehensive loss (“AOCL”) in our condensed consolidated statements of comprehensive loss, and the cumulative effect is included in the stockholders' equity section of our condensed consolidated balance sheets. Realized gains and losses denominated in foreign currencies are recorded in operating expenses in our condensed consolidated statements of operations and were not material to our consolidated results of operations for the
