Prior to the calendar year 1954, each employer’s rate for any calendar year shall be determined on the basis of the employer’s record as of December 31 of the preceding calendar year. For the year 1954 and each calendar year thereafter each employer’s rate for any calendar year shall be determined on the basis of the employer’s record as of September 30 of the preceding calendar year. Variations from the standard rate of assessments shall be determined in accordance with the following requirements:

(1) When, in any benefit year, an employee is first paid benefits for total or partial unemployment, the employee’s wages during the employee’s base period shall be termed the “employee’s benefit wages” and shall be treated, for the purposes of this paragraph, as though they had been earned in the experience year in which such first benefit is paid, except that wages paid to an employee during the employee’s base period for part-time employment by an employer who continues to give the employee employment to the same extent while the employee is receiving benefits as the employee did during the employee’s base period shall not be determined to be employee’s benefit wages. The employer shall establish the continuation of work to the satisfaction of the Department by submitting such information as the Department may require within 4 business days after the notification or mailing of notice by the Department that the employee has first filed a claim for benefits. Wages paid by any individual employer to an employee during the first 90 days such employee is in employment for the employer shall not be considered in determining benefit wages if the said employee is rated as “disabled” by the United States Veterans Administration or as “handicapped” by the Department of Labor.

(2) The “employer’s benefit wages” for any experience year shall be the total of the employee benefit wages of all of such employer’s employees or former employees, except for those employee benefit wages of employees who were hired to fill jobs vacated by members of the National Guard or the Reserve Branch of the United States armed services who were called to active duty during the Persian Gulf crisis.

(3) The “benefit wage ratio” of each employer shall be the percentage obtained by dividing the total of the employer’s benefit wages for the most recent 3 completed experience years by the employer’s total payroll subject to assessments for the same 3 experience years as shown on the employer’s assessment reports.

(4) For any calendar year, the “state experience factor” shall be the term used for the total benefits paid from the Fund during the most recent 3 completed experience years, divided by the total of the benefit wages of all employers during the same 3 years. In such computation, any fraction shall be adjusted to the nearest multiple of 1%.

(5) The basic assessment rate for each employer for the current calendar year shall be determined prior to the due date of the first basic assessment for such year in accordance with the following table:

If the employer’s benefit wage ratio exceeds the percentage in the last column of the table opposite the State Experience Factor, the employer’s basic contribution rate shall be 8%.

(6) No employer’s basic assessment rate or new employer rate for the period of 12 months commencing January 1 of any calendar year shall be less than 63/10% unless all required reports and all assessment due on wages paid for employment for such employer during pay periods ending on or prior to June 30 of the preceding year have been received by the Department on or prior to September 30 of such preceding year. If such required reports and assessments due are received by the Department after September 30 of the preceding year but prior to or on the last day of any calendar quarter of any calendar year, such employer’s basic assessment rate or new employer rate for assessments on wages paid for employment for such employers during pay periods in the said calendar quarter and for wages paid for employment for such employer during pay periods in all succeeding calendar quarters in such calendar year shall be the basic assessment rate as determined for such employer under paragraph (5) of this section or the new employer rate as determined for such employer under § 3348 of this title, whichever the Department determines is applicable.

(7) Effective July 1, 1994, notwithstanding any inconsistent provisions of this chapter, if, after the last day of any claimant’s benefit year but within the 90 days next following thereafter, an employer for whom benefit wage charges were made as a consequence of such claimant’s receipt of benefits files a written notice in such manner as the Department shall prescribe, stating that the employer had reemployed such claimant within the claimant’s benefit year, and the Department finds that such employee received in benefits a total amount aggregating not more than 25% of the maximum benefit payments to which the employee was entitled within such benefit year because of such reemployment, the employer’s benefit wage record shall be credited with 75% of the benefit wages previously charged against the employer relating to such claimant’s previous employment; or if the Department finds that such employee received in benefits an amount aggregating more than 25% but not more than 50% of the maximum benefits to which the employee was entitled within such benefit year because of such reemployment, the employer’s benefit wage record shall be credited with 50% of the benefit wages previously charged against the employer relating to such claimant’s previous employment; or if the Department finds that such employee received in benefits a total amount aggregating more than 50% but not more than 75% of the maximum benefits to which the employee was entitled within such benefit year because of such reemployment, the employer’s benefit wage record shall be credited with 25% of the benefit wages previously charged against the employer relating to such claimant’s previous employment. In computing an employer’s assessment rate for any calendar year, credits may be used only in connection with rehires of claimants whose benefit years ended no later than June 30 of the calendar year immediately preceding. Rehire credits shall be applied to the employer’s benefit wage record in the calendar year and quarter in which the claimant’s benefit year exhausted. An employer may apply for rehire credits relating to a claim for benefits, including benefits paid as a consequence of a claim for partial unemployment benefits, regardless of the number of separate periods of unemployment a claimant had during the claimant’s benefit year.

Employer “rehire credits” as defined above shall not be used in the calculation of the “state experience factor” as determined in accordance with paragraph (4) of this section.

(8) For the last 3 calendar quarters of 1959, the 4 calendar quarters of 1960 and the first calendar quarter of 1961, every rated employer shall pay, in addition to the assessment set for such employer under paragraph (5) of this section, an additional assessment of 11/2% of wages paid by the employer in each of the aforesaid calendar quarters.
