Voyage Expenses and Commissions:
Voyage expenses and commissions decreased by 25.6%, or $3.3 million, from $12.9 million during the six-month period ended June 30, 2020, to $9.6 million during the six-month period ended June 30, 2021. The decrease in voyage expenses and commissions is mainly attributable to a net decrease of $3.4 million in bunker consumption costs due to the increased utilization of our vessels in the spot fleet in the six-month period ended June 30, 2021, as compared to the same period in 2020.
Vessel Operating and Supervision Costs:
Vessel operating and supervision costs increased by 18.0%, or $12.2 million, from $67.7 million during the six-month period ended June 30, 2020, to $79.9 million during the six-month period ended June 30, 2021. The increase in vessel operating and supervision costs is mainly attributable to the increase in ownership days due to the full operation and deliveries of the GasLog Windsor, the GasLog Wales, the GasLog Westminster, the GasLog Georgetown, the GasLog Galveston and the GasLog Wellington on April 1, 2020, on May 11, 2020, on July 15, 2020, on November 16, 2020, on January 4, 2021 and on June 15, 2021, respectively, and also to the increase in daily operating costs from $13,384 per ownership day (as defined below excluding the Solaris managed by Shell) for the six-month period ended June 30, 2020, to $13,773 per ownership day (as defined below excluding the Solaris managed by Shell) for the six-month period ended June 30, 2021. Ownership days represent total calendar days for our owned and bareboat fleet. Daily operating costs per vessel increased mainly due to increased crew costs, as a result of COVID-19 restrictions (costs for travelling and quarantines) and the unfavorable movement of the EUR/USD exchange rate in the six-month period ended June 30, 2021, as compared to the six-month period ended June 30, 2020.
General and Administrative Expenses:
General and administrative expenses increased by 21.2%, or $4.4 million, from $20.8 million during the six-month period ended June 30, 2020, to $25.2 million during the six-month period ended June 30, 2021. The increase in absolute terms is mainly attributable to legal costs, accelerated amortization of the share-based compensation and other employee costs associated with the Transaction, the unfavorable movement of the EUR/USD exchange rate in the six-month period ended June 30, 2021, as well as the increased costs of directors and officers’ insurance, which were partially offset by reduced employee costs due to the restructuring completed in 2020. General and administrative expenses include the effect of the restructuring costs of $1.5 million and $0.1 million for the six-month period ended June 30, 2020, and 2021, respectively and the effect of the costs related to the Transaction of $9.0 million for the six-month period ended June 30, 2021. Daily general and administrative expenses increased from $3,967 per vessel ownership day for the six-month period ended June 30, 2020, to $4,217 per vessel ownership day for the six-month period ended June 30, 2021, which includes restructuring costs of $291 and $24 per vessel ownership day in six-month period ended June 30, 2020, and 2021, respectively and costs related to the Transaction of $1,497 per vessel ownership day in six-month period ended June 30, 2021.
Impairment Loss on Vessels:
Impairment loss on vessels was $22.5 million for the six-month period ended June 30, 2020, and nil for the same period in 2021. The impairment loss recorded as of June 30, 2020, was recognized with respect to four of our Steam vessels (the Methane Rita Andrea, the Methane Lydon Volney, the Methane Shirley Elisabeth and the Methane Heather Sally), as a result of anticipated increases in volatility in the spot charter market over the near term from COVID-19 pandemic related impacts to LNG and LNG shipping demand.
Financial Costs:
Financial costs increased by 6.6%, or $5.6 million, from $85.0 million during the six-month period ended June 30, 2020, to $90.6 million during the six-month period ended June 30, 2021. The increase is mainly attributable to an increase of $16.2 million in other financial costs, net related mainly to the $15.7 million financing fees associated with the amendment of the credit facilities as a result of the Transaction. This increase is partially offset by a decrease of $11.7 million in interest expense on loans and bonds in connection with a decrease in the LIBOR rates during the six-month period ended June 30, 2021, although there was higher weighted average indebtedness, compared to the same period in 2020. Specifically, during the six-month period ended June 30, 2021, we had an average of $3,801.7 million of outstanding indebtedness, with a weighted average interest rate of 3.1%, while during the six-month period ended June 30, 2020, we had an average of $3,259.3 million of outstanding indebtedness, with a weighted average interest rate of 4.3%. These weighted average interest rates include interest expense on loans, bonds and CCSs.
