The U.K. coverage certification is used to assign foreign (F) quarters of coverage
            to the U.S. earnings record.

                     All periods of coverage certified by the United Kingdom are creditable, including
                        non-contributory and non-work related credits granted during periods of invalidity.

                     The presence of U.K. coverage after disability onset is not necessarily an indication
                        of work. Development of substantial gainful activity should not be initiated based
                        only on the U.K. coverage.

                     There is no minimum amount of U.K. coverage which must be earned before the U.S. can
                        use it.
