During the six months ended June 30, 2018, the reserves for unpaid losses and loss adjustment expenses held at December 31, 2017 developed favorably by $3.5 million. The favorable development was primarily attributable to the 2017 accident year of $2.5 million, the 2016 accident year of $3.0 million and the 2015 accident year of $0.8 million, which resulted from reported losses emerging at a lower level than expected. This favorable development was offset in part by adverse development from the 2011 through 2014 accident years of $2.8 million.

During the six months ended June 30, 2017, the reserves for unpaid losses and loss adjustment expenses held at December 31, 2016 developed favorably by $8.9 million. The favorable development was attributable primarily to the 2016 accident year of $5.8 million and the 2015 accident year of $3.7 million, which was due to reported losses emerging at a lower level than expected. The favorable development was offset in part by adverse development of $1.1 million for the 2013 accident year.

Multi-line quota share reinsurance

Effective January 1, 2017, the Company commuted its multi-line quota share treaty ("MLQS") covering the period January 1, 2015 to December 31, 2015, which reduced reinsurance recoverables on unpaid losses by approximately $27.9 million. The commutation did not have any effect on the Company's results of operations or cash flows for the applicable period.
