Depreciation and Amortization
Depreciation and amortization for the first quarter of 2023 was $21.2 million, compared to $19.9 million in the first quarter of 2022. The increase was mainly due to the 11 drydockings completed after March 31, 2022.
General and Administrative Expenses
General and administrative expenses were $4.8 million in the first quarter of 2023, compared to $6.2 million in the first quarter of 2022. The decrease was mainly due to lower stock-based compensation expense in the first quarter of 2023 and a one-off expense that occurred in first quarter of 2022 due to social security charges related to vesting of shares under the stock-based compensation plan. The average general and administrative expense per ownership day for the first quarter of 2023 was $820, compared to $1,066 in the comparative period, a decrease of $246 or 23.1%.

Interest and other finance expenses for the first quarter of 2023 was $11.1 million, down from $18.7 million for the first quarter of 2022.

Including the effect of the interest rate caps and refinancing and repayment of certain of our debt using the net proceeds of our 2027 Secured Notes which closed in June 2022, the blended cost of our debt has decreased from approximately 4.72% for the first quarter 2022 to 4.53% for the first quarter 2023, despite an increase in three-month LIBOR/SOFR in the first quarter of 2023 to 4.92% as compared to 0.53% in the prior year period.
