The following table sets forth the computation of basic and diluted loss per common share during each of the three and six months ended June 30, 2023 and 2022 (amounts in thousands, except per share data):

For the three months ended June 30, 2023 and 2022, 18.2 million and 7.8 million shares, respectively, of potential common stock were excluded from diluted shares outstanding because the effects of potentially dilutive securities would be anti-dilutive. For the six months ended June 30, 2023 and 2022, 19.0 million and 7.6 million shares, respectively, of potential common stock were excluded from diluted shares outstanding because the effects of potentially dilutive securities would be anti-dilutive. Included in these shares as of June 30, 2023 is a portion of the 49.1 million Warrants issued to Partner under the Service Agreements in 2022, which was determined after considering the exercise price of each tranche relative to the average market price during the period. Excluded from the amounts above are warrants expected to be issued to Thermo for its guarantee of the 2023 Funding Agreement totaling 10.0 million; the guarantee is expected to become effective during the third quarter of 2023.

As discussed in Note 5: Long-Term Debt and Other Financing Arrangements, the Company's Board of Directors approved the payment of dividends totaling $2.6 million and $5.3 million for the three and six months ended June 30, 2023, respectively, on its Series A Preferred Stock. This amount adjusts the numerator used to calculate loss per share.
