Contingently Convertible Securities

When CMS Energy has earnings from continuing operations, its contingently convertible securities dilute EPS to the extent that the conversion value of a security, which is based on the average market price of CMS Energy common stock, exceeds the principal value of that security.

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.

Convertible Debentures

CMS Energy redeemed all of its outstanding 7.75 percent Trust Preferred Securities in February 2012.  For each of the nine-month periods ended September 30, 2012 and September 30, 2011, the Trust Preferred Securities would have increased diluted EPS had they been included in the calculation.  Using the if‑converted method, the debentures would have had the following impacts on the calculation of diluted EPS:
