Leases [Abstract] |
Leases | 9. Leases The Company leases certain equipment and buildings under operating lease arrangements. Most leases are for a fixed term and for a fixed amount; additionally, the Company leases certain buildings under operating leases on a month-to-month basis. The Company is not a party to any leases that have step rent provisions, escalation clauses, capital improvement funding or payment increases based on any index or rate. Future minimum payments under non-cancelable operating leases with initial or remaining terms in excess of one year during each of the next five years follow:
2012 |  | $ | 944,365 |
2013 |  |  | 727,034 |
2014 |  |  | 91,594 |
2015 |  |  | 23,464 |
2016 |  |  | 18,776 |
|  | $ | 1,805,233 |
Rent expense for all operating leases was $1,243,494 in 2011, $1,049,046 in 2010 and $758,606 in 2009. The Company expects future rent expense, including non-cancelable operating leases, leases that are expected to be renewed and buildings leased on a month-to-month basis, for each of the next five years to be in the range of $1,100,000 to $1,300,000.
