Greece's payment to the IMF is due no later than 6pm Washington time on 30 June 2015; that's 2200GMT.
If they miss payment to the IMF its not termed a 'default'
- A missed payment puts Greece in IMF "arrears", not in "default".
- Being in arrears means it won't be eligible for IMF aid until the bill is paid
It's the big 3 ratings agencies that use the term 'default' ... and it applies if Greece fails to pay back private sector debts, not public ones
- The next private debt repayment is due on July 14 ... a Y20bn note (a 20-year-old samurai bond) matures on that day
