HOUSTON (AP) — EOG Resources Inc. said Thursday it lost $505 million in the fourth quarter, hurt by charges stemming from drops in the values of some of its Canadian natural gas assets.

The Houston-based oil and gas producer’s loss amounted to $1.88 per share and compared with net income of $120.7 million, or 45 cents per share, a year ago. Excluding the charges related to the Canadian assets and other one-time items, the company said it posted an adjusted profit of $1.61 per share for the recent quarter.
