Debt Instrument [Line Items] |
Debt Instrument, Description of Variable Rate Basis | loans and credit facilities bear interest at LIBOR plus a margin, except for each of Maxeikosi, Maxeikosiena, Maxeikositria and Youngone and for a portion of each of Maxdeka and Shikoku loan facilities. Maxdeka and Shikoku had entered into loan facilities with government owned export credit institutions, each bearing interest at the Commercial Interest Reference Rate (“CIRR”) published by the Organization for Economic Co-operation and Development, as applicable on the date of the signing of the relevant loan agreements. Each of the Maxeikosi, Maxeikosiena, Maxeikositria and Youngone loan facilities are deemed to incur interest at a fixed rate calculated so that the initial facility amount be amortised to maturity down to the purchase obligation price of each vessel.
Debt Instrument, Frequency of Periodic Payment | loans and credit facilities are generally repayable by quarterly principal installments and a balloon payment due on maturity, with the exception of the Maxdeka and Shikoku loan facilities which are repaid by semi-annual principal instalments without a balloon payment due on maturity and the Maxeikosi, Maxeikosiena, Maxeikositria and Youngone loan facilities, that are deemed to be repaid by principal installments every 45 days out of a portion of the bareboat hire payment and a balloon payment due on maturity equal to the purchase obligation.
