A reserve maintenance cycle includes the computation period for reserves and the associated maintenance period or periods in which the reserves are maintained. When used in reference to weekly reporters, the reserve maintenance cycle consists of a fourteen-day computation period and its associated fourteen-day maintenance period, which begins seventeen days after the end of the computation period.
When used in reference to quarterly reporters, the reserve maintenance cycle consists of a seven-day computation period (in March, June, September, or December) and an interval of six or seven consecutive fourteen-day maintenance periods. The interval will begin on the fourth Thursday following the end of each quarterly reporting period if that Thursday is the first day of a two-week maintenance period. If the fourth Thursday following the end of a quarterly reporting period is not the first day of a two-week maintenance period, then the interval will begin on the fifth Thursday following the end of the quarterly reporting period.
