Revises the definition of "small employer" to mean an employer who employs an average of at least one but not more than 50 employees on business days during the preceding calendar year and who employs at least one employee on the first day of the plan year (rather than an employer who employs an average of at least 2 employees on business days during the preceding calendar year and who employs at least 2 employees on the first day of the plan year). Effective immediately.
