(1) "Base year" with respect to benefit years commencing on or after July 1, 1986, shall mean the first four of the last five completed calendar quarters immediately preceding an individual's benefit year.
With respect to a benefit year commencing on or after July 1, 1995, if an individual does not have sufficient qualifying weeks or wages in his base year to qualify for benefits, the individual shall have the option of designating that his base year shall be the "alternative base year," which means the last four completed calendar quarters immediately preceding the individual's benefit year; except that, with respect to a benefit year commencing on or after October 1, 1995, if the individual also does not have sufficient qualifying weeks or wages in the last four completed calendar quarters immediately preceding his benefit year to qualify for benefits, "alternative base year" means the last three completed calendar quarters immediately preceding his benefit year and, of the calendar quarter in which the benefit year commences, the portion of the quarter which occurs before the commencing of the benefit year.
The division shall inform the individual of his options under this section as amended by P.L.1995, c.234. If information regarding weeks and wages for the calendar quarter or quarters immediately preceding the benefit year is not available to the division from the regular quarterly reports of wage information and the division is not able to obtain the information using other means pursuant to State or federal law, the division may base the determination of eligibility for benefits on the affidavit of an individual with respect to weeks and wages for that calendar quarter. The individual shall furnish payroll documentation, if available, in support of the affidavit. A determination of benefits based on an alternative base year shall be adjusted when the quarterly report of wage information from the employer is received if that information causes a change in the determination.
