In February 2012, Charles Schwab (NYSE: SCHW) introduced its ETF OneSource platform, a collection of commission-free ETF offerings from Schwab and several other major issuers.

A year later, it is clear OneSource has been a success. Data have consistently supported the notion that expenses and fees are important parts of the decision-making process for advisors and investors when evaluating ETFs. Statistics also show cost-conscious advisors and investors continue embracing OneSource.

As of the end of January, OneSource was home to $24 billion in assets under management, a 66% year-over-year increase, the company said on call Friday. Inflows to OneSource by Schwab clients jumped 42% while flows to third party ETFs on the platform tripled. [Schwab Rolls Out OneSource Platform]
