Cal. Gov. Code § 82025

“Expenditure” means a payment, a forgiveness of a loan, a payment of a loan by a third party, or an enforceable promise to make a payment, unless it is clear from the surrounding circumstances that it is not made for political purposes. “Expenditure” does not include a candidate’s use of his or her own money to pay for either a filing fee for a declaration of candidacy or a candidate statement prepared pursuant to Section 13307 of the Elections Code. An expenditure is made on the date the payment is made or on the date consideration, if any, is received, whichever is earlier.
