Example 1.

Mr. J, who became age 65 and otherwise eligible for enrollment in November 1965, first enrolls in March 1968. The months to be included in determining the amount of the increase in Mr. J's premiums begin with June 1966 (the first month after the close of his initial enrollment period) and extend through December 1967 (the period January through March of 1968 is excluded in determining the total months) for a total of 19 months. Since there is only one full 12-month period in 19 months, Mr. J's premiums will be 10 percent greater than if he had enrolled in his initial enrollment period.

Example 2.

Mr. V, who enrolled in December 1965, voluntarily terminates his enrollment effective midnight December 31, 1967. He enrolls for a second time in January 1969. The months to be included in determining the amount of the increase in Mr. V's premiums are January 1968 through March 1969, a total of 15 months. Since this totals one full 12-month period. Mr. V's monthly premium, will be increased by 10 percent.
