Contingently Convertible Securities In June 2014, CMS Energy redeemed its remaining contingently convertible securities. For the periods those securities were outstanding, they diluted EPS to the extent that the conversion value of the securities, which was based on the average market price of CMS Energy common stock, exceeded their principal value. Non‑vested Stock Awards CMS Energy’s non‑vested stock awards are composed of participating and non‑participating securities. The participating securities accrue cash dividends when common stockholders receive dividends. Since the recipient is not required to return the dividends to CMS Energy if the recipient forfeits the award, the non‑vested stock awards are considered participating securities. As such, the participating non‑vested stock awards were included in the computation of basic EPS. The non‑participating securities accrue stock dividends that vest concurrently with the stock award. If the recipient forfeits the award, the stock dividends accrued on the non‑participating securities are also forfeited. Accordingly, the non‑participating awards and stock dividends were included in the computation of diluted EPS, but not basic EPS.
