Reconciliation checks needing review

3 periods on this page do not reconcile under this site’s normalization. Read that as a limitation here before an observation about the company: the figures are the filer’s own, the filings linked above are authoritative, and a difference usually means the concepts this site selected do not match how this filer presents its statements. Nothing is adjusted to make a check pass.
