Official announcements are as follows: 

"Our contract with 2NE1 came to an end in May of 2016, and as we faced a situation where Minzy is no longer with us, we ultimately came to a decision of 2NE1's official disbandment after long discussion.  

For the past 7 years, 2NE1 was a representative group of YG. We, too, cannot express how upset and disappointed we are. However, we judge that it'll be difficult to continue promoting. We decided that instead of looking forward to 2NE1's unpredictable promotions, we should rather focus on the solo promotions of the members.

We sincerely appreciate everyone who loved 2NE1 and their music.

Meanwhile, in May, YG renewed the contract with CL and Dara. Unfortunately, we officially announce that Park Bom did not have a renewal."

"WINNER, who announced to have active promotions this year, unfortunately, had to halt all promotions due to Nam Tae Hyun's mental health issues. YG and rest of the members looked forward to and considered first and foremost for Nam Tae Hyun's recovery. 

However, it's a mental issue he struggled with since young age, and his recovery and return are unpredictable. Therefore, we judged that it's impossible for him to carry on promotions with WINNER. 

We are officially announcing that as of November 18, our contract with Nam Tae Hyun came to an end. We believe that the pressure on Nam Tae Hyun in causing issues to the group can no longer be halting the promotion of WINNER who's only a group of 2 years. 

Nam Tae Hyun can no longer be with WINNER, however, we wish for them to remain colleagues who can give support for each other's individual music promotions. 

YG plans to officially start preparing for WINNER's promotions with 4 members without any new addition to the group. Please give great support and encouragement for Nam Tae Hyun and WINNER who's facing a new start as a group of 4."
