Convertible Preferred Shares
In May 2018, we issued 5,750,000 (including the underwriters option for 750,000) of our 6% Series A Mandatory Convertible Preferred Shares (the “mandatory convertible preferred shares”), par value $.001 per share, with a liquidation preference of $50 per share. Nabors received aggregate net proceeds of approximately $277.9 million after deducting underwriting discounts, commissions and offering expenses. In June 2019, we repurchased 4,000 of our mandatory convertible preferred shares for approximately $.08 million.
The dividends on the mandatory convertible preferred shares are payable on a cumulative basis at a rate of 6% annually on the initial liquidation preference of $50 per share. Dividends accumulate and are paid quarterly to the extent that we have available funds and our Board of Directors declares a dividend payable. We may elect to pay any accumulated and unpaid dividends in cash or common shares or any combination thereof. At issuance, each mandatory convertible preferred share was automatically convertible into between 5.3763 and 6.4516 of our common shares based on the average share price over a period of twenty consecutive trading days ending prior to May 1, 2021, subject to anti-dilution adjustments. As a result of the dividends paid on our common shares since the offering, the most recent publicly announced conversion rate for each mandatory convertible preferred share is between 5.6179 and 6.7416 of our common shares. Adjustments to the conversion ratio are required to be made and published when such adjustment would result in an increase or decrease of one percent or more of the conversion rate. At any time prior to May 1, 2021, a holder of mandatory convertible preferred shares may convert such mandatory convertible preferred shares into our common shares at the minimum conversion rate, subject to adjustment.
