Subsequent Events [Abstract]
Subsequent Events	Note 18. Subsequent Events As more fully discussed in Note 3, the Company completed the sale of its State of New Jersey net operating loss and received the $1.8 million in proceeds from the sale in April 2020. On April 23, 2020, we filed a Current Report on Form 8-K announcing we entered into a loan agreement with Silicon Valley Bank (the “PPP Loan”), pursuant to the Paycheck Protection Program of the Coronavirus Aid, Relief, and Economic Security Act. We thereafter received proceeds of $632,220 under the PPP Loan. The PPP Loan application required Celsion to certify that there was economic uncertainty surrounding the Company and that, as such, the PPP Loan was necessary to support our ongoing operations. Celsion made this certification in good faith after analyzing, among other things, its financial situation and access to alternative forms of capital, and believes that the Company satisfied all eligibility criteria for the PPP Loan, and that our receipt of the PPP Loan proceeds was consistent with the broad objectives of the PPP of the CARES Act. The certification given with respect to the PPP Loan does not contain any objective criteria and is subject to interpretation. In light of subsequent guidance issued by the U.S. Small Business Administration in consultation with the U.S. Department of the Treasury, out of an abundance of caution we returned the proceeds of the PPP Loan in full on May 13, 2020. Celsion may choose to reapply for the loan if the SBA provides future applicable guidance. As disclosed in Note 10, the Company and Horizon agreed to defer the first two principal payments totaling a $833,333 due in August and September 2020.

As more fully discussed in Note 3, the Company completed the sale of its State of New Jersey net operating loss and received the $1.8 million in proceeds from the sale in April 2020.

On April 23, 2020, we filed a Current Report on Form 8-K announcing we entered into a loan agreement with Silicon Valley Bank (the “PPP Loan”), pursuant to the Paycheck Protection Program of the Coronavirus Aid, Relief, and Economic Security Act. We thereafter received proceeds of $632,220 under the PPP Loan. The PPP Loan application required Celsion to certify that there was economic uncertainty surrounding the Company and that, as such, the PPP Loan was necessary to support our ongoing operations. Celsion made this certification in good faith after analyzing, among other things, its financial situation and access to alternative forms of capital, and believes that the Company satisfied all eligibility criteria for the PPP Loan, and that our receipt of the PPP Loan proceeds was consistent with the broad objectives of the PPP of the CARES Act. The certification given with respect to the PPP Loan does not contain any objective criteria and is subject to interpretation. In light of subsequent guidance issued by the U.S. Small Business Administration in consultation with the U.S. Department of the Treasury, out of an abundance of caution we returned the proceeds of the PPP Loan in full on May 13, 2020.
