After reading the very concise and accessible report on the state of the study, I got the impression that the $1.3 billion had been allocated by Congress but that little or none of it had been spent, basically because the study design never got close enough to being finalized and approved for any large-scale data acquisition to even take place. Unless I'm quite mistaken, the $1.3 billion has been parked on the NIH's balance sheet for the last several years rather than being lost.

edit: this page suggests about 60% of the funding was spent: https://www.nationalchildrensstudy.gov/about/funding/Pages/i...

I too am having trouble finding "Spent" vs. "Allocated".

Edit: I'm not anymore. http://www.nationalchildrensstudy.gov/about/funding/Pages/in... appears to be decent for at least the recent past.
