What describes a transistor in cutoff?

In cutoff, the transistor is effectively off, so the base-emitter junction is not forward biased and the device conducts no significant current from collector to emitter. This means there is essentially no current between emitter and collector (the path is effectively open). In practice there may be a tiny leakage current, but it is negligible. The other descriptions refer to different operating conditions: for example, some base current would imply the device isn’t fully off, and maximum current occurs when the transistor is saturated, not in cutoff.
