Slide the table for earlier years · "·" marks a figure not available in our data for that year.
Growth
Compound annual rates per period — left blank where that exact year isn't on file, the series crosses a loss, or (per-share rows) a split falls inside the window.
Profitability
Not applicable: equity was zero or negative in this period, so return on equity has no meaning.
Each USD of equity lost 35 cents this year.
The 3-year record
EPS, diluted, dividend per share and shares outstanding are shown without shading, and a vertical line marks the year the share count changed — the series crosses a large, unexplained change in share count, so the years on either side are not on a comparable scale.
