Cost Basis for Company Buyout/Holding Period

Stock/equity in Company (X) which was Acquired by a publicly traded company (Company Y) which happened on March 1, 2021. 

Legal Document from company Y says I purchased the stock on March 1, 2021--word purchased in the agreement. 

I assume it was Like-Kinded Exchange. 

Subject to 1 Year Holding Period------The Value of the Stock (March 1, 2021) on Purchase Date March 1 was $20 a share. 

I held the stock for the required year and I sell the Stock on March 15, 2022 and I sell the stock for $5 a share,

 

Am I eligible to take a $15 per share capital loss? 

 

Not employee of the company but held equity as a founder
