 from vessels. Effective May 2005, Annex VI sets limits on sulfur oxide and nitrogen oxide emissions from all commercial vessel exhausts and prohibits “deliberate emissions” of ozone depleting substances (such as halons and chlorofluorocarbons), emissions of volatile compounds from cargo tanks and the shipboard incineration of specific substances. Annex VI also includes a global cap on the sulfur content of fuel oil and allows for special areas to be established with more stringent controls on sulfur emissions, as explained below. Emissions of the shipboard incineration (from incinerators installed after January 1, 2000) of certain substances (such as polychlorinated biphenyls, or “PCBs”) are also prohibited. We believe that all our vessels are currently compliant in all material respects with these regulations.

The Marine Environment Protection Committee, or “MEPC,” adopted amendments to Annex VI regarding emissions of sulfur oxide, nitrogen oxide, particulate matter and ozone depleting substances, which entered into force on July 1, 2010. The amended Annex VI seeks to further reduce air pollution by, among other things, implementing a progressive reduction of the amount of sulfur contained in any fuel oil used on board ships. On October 27, 2016, at its 70th session, the MEPC agreed to implement a global 0.5% m/m sulfur oxide emissions limit (reduced from 3.50%) starting from January 1, 2020. This limitation can be met by using low-sulfur compliant fuel oil, alternative fuels or certain exhaust gas cleaning systems. Ships are now required to obtain bunker delivery notes and International Air Pollution Prevention (“IAPP”) Certificates from their flag states that specify sulfur content. Additionally, at MEPC 73, amendments to Annex VI to prohibit the carriage of bunkers above 0.5% sulfur on ships, with the exception of vessels fitted with exhaust gas cleaning equipment (“scrubbers”) which can carry fuel of higher sulfur content, were adopted and took effect March 1, 2020. Additional amendments to Annex VI became effective in April 2022, and revised, among other terms, the definition of “Sulphur content of fuel oil” and “low-flashpoint fuel” and pertain to the sampling and testing of onboard fuel oil. Additional amendments to Annex VI, requiring bunker delivery notes to include a flashpoint of fuel oil or a statement that the flashpoint has been measured at
