Earnings were insufficient to cover fixed charges by $20.2 million for the nine months ended September 30, 2018, $17.8 million in 2017, $21.8 million in 2016, and $23.0 million in 2015.
For the periods indicated above, we had no outstanding shares of preferred stock with required dividend payments. Therefore, the ratios of earnings to combined fixed charges and preferred stock dividends are identical to the ratios presented in the tables above.
