The lieutenant governor's office is still reviewing the complaint and likely won't take any action for several weeks, according to Mark Thomas, the administrator of the office.
The alleged omissions include P-Solutions, a company that was held by Swallow and his wife that received $23,500 in consulting payments from Richard Rawle, the late founder of the Provo-based Check City payday-loan franchise.
Rawle had received the money from Jeremy Johnson as part of a deal Swallow helped arrange to help Johnson avoid a lawsuit by the Federal Trade Commission alleging deceptive business practices at Johnson's I Works company.
Swallow insists the payment was for consulting work on a cement plant and was unrelated to the Johnson deal and says he returned the money, seeking payment from another account.
The stake in P-Solutions and other companies was not listed on his original financial-disclosure form. Swallow removed his name from the management of several companies several days later and filed a new disclosure but still did not include his wife's stake in the companies.
A federal investigation is also under way into Swallow's conduct.
Herbert also signed HB44, sponsored by Rep. Greg Hughes, R-Draper, which requires polling companies to disclose who is paying for their services. And he signed HB100, sponsored by Rep. Stewart Barlow, R-Fruit Heights, which prevents employers from demanding workers share their usernames and passwords for their online accounts.
The governor also approved SB103, expanding the Carson Smith Scholarship program, a voucher system to help the parents of special-needs students pay for their education. And he signed SB98, which makes it a class B misdemeanor to propel saliva, feces or other bodily substances at someone and a class A misdemeanor if the substance is infected with HIV or hepatitis.
Lawmakers passed more than 500 bills that require action by the governor. So far he has signed 187 and vetoed one bill, which would have changed Utah's concealed-weapons laws.
