This section applies where—
Times before 6 April 2015 are to be ignored in determining whether or not condition A in section 223 is met in relation to a period of absence, unless P elects that this subsection is not to apply in relation to the period.
An election under subsection (2)—
Where P has made an election under subsection (2), section 223 applies as if relevant prior periods of absence counted against the maximum periods (and maximum aggregate periods) specified in subsection (3)(a), (c) and (d) of that section.
In relation to a maximum period (or maximum aggregate period) specified in paragraph (a), (c) or (d) of section 223(3), "relevant prior period of absence" means a period of absence which would have counted against that maximum period (or maximum aggregate period) if the bridge period were included in the period of ownership.
In subsection (5) "the bridge period" means the period beginning with the day specified in the election and ending with 5 April 2015.
In this section "period of absence" has the same meaning as in section 223.
