Does having an unannounced audit for an operation enrolled in Option A1/A2 affect their audit cycle or random audit selection?

If an operation is enrolled in Option A1 or A2 (4-year audit cycle), there is no change to the way the audit cycle or random audits work. The operation will still be informed in advance if they are randomly selected for an audit. However, they may not be told the exact date of the random audit (i.e., it could be unannounced).
