  the  allocation of the band 415-495 kHz to the
  aeronautical radionavigation service is on a
  primary basis. Administrations in these countries
  shall take all practical steps necessary to
  ensure that aeronautical radionavigation stations
  in the band 435-495 kHz do not cause interference
  to reception by coast stations of ship stations
  transmitting on frequencies designated for ship
  stations on a worldwide basis (see
  No. 52.39).     (WRC-2000)No proposals from these
  States to remove their name
• The proposal to remove Indonesia from this
  footnote does not affect the AFI Region ICAO has
  no opinion on this proposal
