(e) An employer's account shall not be relieved of charges relating to a payment that was made erroneously from the unemployment compensation fund after July 1, 2013 if the department determines that:

(i) The erroneous payment was made because the employer, or the agent of the employer, was at fault for failing to respond timely or adequately to a written request, sent by United States mail or by electronic mail, from the department for information relating to the claim for benefits which resulted in the erroneous payment; and

(ii) The employer or agent has established a pattern of failing to respond timely or adequately to requests similar to those identified in paragraph (i) of this subsection.

(f) For purposes of subsection (e) of this section, "timely" means within fifteen (15) days after a notice or request is sent by United States mail or by electronic mail to the address of record of the employer or employer's agent.

27-3-507. Person acquiring trade of employing unit; transfer of experience and assignment of rates.  (a) A person acquiring the trade, organization, business or substantially all the assets of an employer subject to this act shall assume the employer's account, benefit experience and contribution rate. If the acquiring person is an employer subject to this act, the department shall consolidate the separate accounts and benefit experience and shall determine the contribution rate of the acquiring person effective the first day of the calendar quarter following the date of acquisition. A delinquency rate shall be assumed by the acquiring person as provided in W.S. 27-3-503(b) when the acquiring person owned or controlled an interest in the transferring employer or if the acquiring person is a member of the immediate family of the transferring employer.

(b) The transfer of some or all of an employer's workforce to another person shall be considered a transfer of trade or business when, as a result of the transfer, the transferring employer no longer performs trade or business with respect to the transferred workforce, and the trade or business is performed by the person to whom the workforce is transferred.

(c) If an employer transfers all or a portion of its trade or business to another employer and, at the time of the transfer, there is substantially common ownership, management or control of the two (2) employers, then the unemployment insurance experience attributable to the transferred trade or business shall be transferred to the employer to whom the business is transferred. The rates of both employers shall be recalculated and made effective the first day of the calendar quarter immediately following the date of the transfer of trade or business. Both employers may be given a delinquency rate as provided in W.S. 27-3-503(b) if applicable.

(d) If, following a transfer of experience under this section, the department determines that a substantial purpose of the transfer of the trade or business was to obtain a reduced liability for contributions, then the accounts of the employers involved shall be combined into a single account and a single rate assigned to the account.

(e) If a person is not an employer under this section at the time the person acquires the trade or business of an employer, the unemployment insurance experience of the acquired employer shall not be transferred to the person if the department finds that the person acquired the trade or business of the employer solely or primarily for the purpose of obtaining a lower rate of contributions. Instead, the person shall be assigned the applicable new employer rate under W.S.
