The Mohegan Tribal Gaming Authority announced quarterly fiscal results Wednesday that illustrate the continued pressure at its gambling resorts in Uncasville and Wilkes-Barre, Pa.

Combined net revenues of $316.7 million for the three-month period ending March 31 were down 2.8 percent compared with the same period a year before. Income from operations was $45.1 million, down 19 percent from the same period a year earlier. The gaming authority begins its fiscal year on Oct. 1, and the three-month period ending March 31 is its second fiscal quarter.

"Considering a number of factors outside our control, including unfavorable weather, a continued sluggish economic backdrop and tough comparisons, our properties performed quite well during our second fiscal quarter compared to many of our regional gaming peers," the gaming authority's CEO Mitchell Grossinger Etess said in a statement.

"With that being said, we continue to pursue new measures to improve efficiencies at our properties and explore initiatives to diversify into new jurisdictions."

Net revenues at Mohegan Sun in Uncasville were $243.5 million for the quarter, down from $252.7 million during the same period in 2013. Quarterly gaming revenues at Mohegan Sun declined to $210.5 million from $222.8 million a year earlier. Non-gaming revenues during the quarter increased to $49.9 million from $46.8 million in 2013.

Mohegan Sun at Pocono Downs in Wilkes-Barre, Pa., had a slight increase in net revenues for the quarter to $73 million from $72.6 million in 2013. Quarterly gaming revenues were down slightly to $67.9 million from $68.6 million during the same period in 2013. Non-gaming revenues were up 30 percent to $10.4 million from $8 million.

Mohegan's pursuit of a casino license in Massachusetts is costing untold millions. The tribe said its 27 percent increase in operational losses within the corporate division — to $9.69 million for the quarter compared with $7.61 million during the same period a year before — was due primarily to the increase in expenses related to the pursuit of a casino license in the Bay State.

The tribe is competing against hotel-and-casino magnate Steve Wynn for the sole license to operate a casino in Greater Boston. Mohegan Sun got a vote of support in February from residents of Revere, Mass., where the tribe wants to build a gambling resort on the grounds of Suffolk Downs racetrack. The Massachusetts Gaming Commission is expected to award a license later this spring or this summer.
