Wynn Resorts said in a securities filing Tuesday it is spending roughly $3.5 million a day to pay its 15,000 employees salary and benefits through May 15. The company, whose properties in Las Vegas and Boston are closed through the beginning of May due to the COVID-19 coronavirus pandemic, was seeking $600 million in financing through two subsidiaries in a private offering. The figure was upsized Tuesday afternoon. The company announced in the morning it was seeking $350 million.
