Is Neiman Marcus owned by Bergdorf Goodman?

Excuse me, I was just reading about some of the top luxury retailers and I came across Neiman Marcus and Bergdorf Goodman. Could you clarify for me if Neiman Marcus is owned by Bergdorf Goodman? I'm a bit confused about the ownership structure between these two companies. I understand they're both high-end retailers, but I'm not sure if they're part of the same corporate umbrella. Thank you in advance for your clarification.
