So, you didn't mean 2215.

It's always best to start at the beginning:

2115. (a) A foreign corporation (other than a foreign association
or foreign nonprofit corporation but including a foreign parent
corporation even though it does not itself transact intrastate
business) is subject to the requirements of subdivision (b)
commencing on the date specified in subdivision (d) and continuing
until the date specified in subdivision (e) if:
(1) The average of the property factor, the payroll factor, and
the sales factor (as defined in Sections 25129, 25132, and 25134 of
the Revenue and Taxation Code) with respect to it is more than 50
percent during its latest full income year
