(a) | Gross margin and net income to common shareholders includes an $8.5 million pre-tax charge for stucco-related repair costs in certain of our Florida communities (as more fully discussed in Note 8 to our Consolidated Financial Statements) taken during the second quarter of 2017, and $7.7 million of impairment charges taken during the fourth quarter of 2017.
(b) | Gross margin and net income to common shareholders includes $2.2 million, $2.8 million and $14.5 million of pre-tax charges for stucco-related repair costs in certain of our Florida communities (as more fully discussed in Note 8 to our Consolidated Financial Statements) taken during the first, second and third quarter of 2016, respectively, and $4.0 million of impairment charges taken during the fourth quarter of 2016.
(c) | Due to rounding, the sum of quarterly results may not equal the total for the year. Additionally, quarterly and year-to-date computations of per share amounts are made independently.
We typically experience significant seasonality and quarter-to-quarter variability in our operating results. In general, homes delivered increase substantially in the second half of the year compared to the first half of the year as we sell more homes during the first and second quarters which results in more homes being delivered in the third and fourth quarters.
