The awards ceremony, which marks the 37th anniversary of the international prize, was held in New York. Pulitzer prize-winning playwright Marsha Norman ('night, Mother; The Bridges of Madison County) opened the ceremony with a speech about the prize's impact on playwright.

Rebecca Hall, who starred in the Broadway revival of Sophie Treadwell's play Machinal, presented Tena Štivičić with an award of $25,000 and a signed and numbered print by artist Willem de Kooning.

Here's how 3 Winters is described: "Premiered by London's National Theatre, 3 Winters is a sweeping family saga set in Zagreb, Croatia, in the years 1945-2011. 3 Winters creates a portrait of an eclectic family held together by generations of formidable women. Through the lens of one family's struggle and triumphs, we witness the story of Croatia, from the remnants of monarchy to Communism, democracy, war and the EU."
