Second, our new building construction program progressed according to schedule. We expect to take delivery of our four remaining 13100 TEU new vessels in March and April this year, all of which we’ve commenced 12-year charter with COSCO.
Third, our Board declared dividend on our common stock and our Series C preferred shares. We remain committed to growing our common share dividend in a suspendable manner that preserves our financial strength and our ability to expand our fleet. In line with our commitment, I am pleased to announce that we have increased our first quarter 2011 quarterly common share dividend by 33%, $0.25 per share.
Fourth and finally, we continue to execute innovative transaction that demonstrates the focus on long-term shareholder value. As previously announced we entered into bareboat charters for remaining 4800 TEU vessels locking an income for the next five years and effectively removing our operating closure to our oldest vessel. And we completed $53 million non-recourse from the lease back arrangements with a leading American bank for 4250 TEU vessel, [NV] UASC Madinah.
In January 2012, we repurchased 11.3 million shares of our Class A common stock through a fixed-price tender offer at $15 per share, and we acquired our Manager and our Class C common stock for $54 million in common shares. In addition, we have authorized up to $50 million share repurchase program, highlighting both confidence in our future prospects and commitment to enhancing shareholder value.I would now like to turn the call over to Sai to discuss our quarterly financial results.
