Charlie Munger had a big birthday party planned for New Year's Eve when he would have turned 100 years old

• Charlie Munger, Warren Buffett's right-hand man at Berkshire Hathaway, died at age 99 on Tuesday.
• He had planned his birthday party which would have fallen on New Year's Eve, according to CNBC.

Charlie Munger, Berkshire Hathaway's vice chairman and investing legend, had plans in place for his birthday on New Year's Eve when he would have turned 100 years old, CNBC reported Tuesday.

CNBC's Becky Quick said on "Closing Bell Overtime" that the publication had been trying to put together a package for his upcoming birthday in five weeks.

"He would have been turning 100 on January 1," she said. "He had a big birthday party planned for New Year's Eve."

In a recent unaired interview with Munger, Quick asked if he had anything left on his bucket list of things he'd like to do.

"I am so old and weak compared to what I was when I was 96 that I no longer want to catch a 200-pound tuna," Munger responded in the interview. "It's just too goddamn much work, it takes too much physical strength. I would have paid any amount to catch a 200-pound tuna when I was younger and never caught one. And now given the opportunity, I would just decline going. I would only go out after it. There are things you give up with time."

Quick commented that the 99-year-old had a busy social life including Zoom meetings and going out to breakfast and lunch.

Munger said: "I like it that way. That's my idea of old age for me and I didn't plan it that way. It just happened. And when it happened, I welcomed it."

Munger died peacefully at a California hospital on Tuesday Morning, his family told Berkshire Hathaway.

"Berkshire Hathaway could not have been built to its present status without Charlie's inspiration, wisdom and participation," Warren Buffett said in a statement.

He led Berkshire Hathaway alongside Buffett since 1978 and amassed a $2.6 billion fortune along the way.

Munger told Quick in the interview that he lived in the same house for decades even as he got richer and his rich friends built bigger and better houses.

"I still decided not to live a life where I look like the Duke of Worcester or something and I was going to avoid it. I did it on purpose … I didn't think it would be good for the children."
