What is the specific meaning of "Net new Assets" at brokerages?

[Brook2]

I read this paragraph in an article and I don't understand what they are referring to as 'net new assets.' In this example, does bringing in net new assets means 1) Their stock value went up because people bought a lot 2) People bought a lot of their CD's or 3) People transferred their accounts to Schwab?

"This week, reports note Charles Schwab brought in $16.5 billion in net new assets. With 34 million account holders, it was clear that most of them didn’t especially care about the trouble surrounding the bank, including the massive sell-off. While certainly, the troubles at other banks hit Schwab hard, it was still regarded as a “safe haven” among financial institutions. In fact, Credit Suisse—itself no stranger to trouble this week—considered Charles Schwab enough of a safe haven to upgrade it to “outperform.”

3b. The value of assets that customers moved from elsewhere to Schwab minus the value of assets that customers moved from Schwab to elsewhere was $16.5 billion during that week.
