Included in accounts payable and accrued expenses at December 31, 2013, 2012, and 2011 were $16.1 million, $8.6 million, and $6.2 million of accrued capital expenditures, respectively.

Pursuant to the application of FASB authoritative guidance to the Company’s lease of office and laboratory facilities in Tarrytown, New York (see Note 13a), the Company recognized a facility lease obligation of $25.0 million during 2013 in connection with capitalizing, on the Company's books, the landlord's costs of constructing new facilities that the Company has leased. The Company did not recognize any such facility lease obligations during 2012 and 2011.

Included in facility lease obligations and property, plant, and equipment at December 31, 2013 was $1.9 million of capitalized and deferred interest for the year ended December 31, 2013, as the related facilities are currently under construction. For the years ended December 31, 2012 and 2011, the Company did not capitalize any interest.

Included in other assets at December 31, 2013 and 2012 were $1.2 million and $3.8 million, respectively, due to the Company in connection with employee exercises of stock options. Such amount was not material at December 31, 2011.
