A pair of luxe Scottish golf resorts operated by Donald Trump suffered millions of dollars in losses during 2015, according to recent filings with a U.K. government agency, adding another complication to Trump's pitch for the White House, in which he has frequently emphasized his business acumen.

Golf Recreation Scotland Limited, which operates the Trump Turnberry luxury resort in Ayrshire, reported a loss of about 8.4 million British pounds (about $12.4 million at the time) in 2015, according to a filing with Companies House, an agency that collects information from companies and makes it available to the public.

The course underwent an expensive renovation that was completed earlier this year. On the filing, Trump's son Eric Trump, who like his father is listed as a director, writes that "the operating loss before depreciation and foreign exchange for the nine months pre closure period" that ended on Sept. 30, 2015, was 254,000 pounds, and the loss for the financial year "before depreciation, amortisation and foreign exchange" was 1.65 million pounds.

Eric Trump wrote in the filing that revenue is expected to increase after the renovation.

Trump International Golf Club Scotland Limited, which oversees the Trump International Golf Links near Aberdeen, suffered an operating loss of nearly 1.1 million British pounds (about $1.6 million at the end of 2015), according to its filing.

According to previous filings for the resort, Trump lost more than 4.7 million pounds dating back to 2012.

Trump's presidential campaign did not immediately respond to a request for comment on the losses.

Trump traveled to Scotland in June to promote his properties. As The Washington Post reported at the time, he attended a ribbon-cutting ceremony at the renovated Trump Turnberry as the value of the pound dropped significantly amid Britain's vote to exit the European Union.

Separately, the Trump Taj Mahal hotel and casino in Atlantic City officially closed for good on Monday. Billionaire investor Carl Icahn, who owned the property, blamed the closure on a dispute with the casino’s unionized employees, who went on strike in July.

Trump called the the 42-story building “the eighth wonder of the world" when he opened it in 1990.
