Stock Based Compensation

In January 2013, the Partnership granted 30,200 restricted units pursuant to the management incentive compensation program. These restricted units vest ratably over four years with the grant date fair value equal to the market price on the date of grant. Simultaneous with the restricted unit grant to management, members of our Board of Directors received 6,000 restricted units. Restricted units granted to directors are not part of the management incentive compensation program, but are included in the calculation of total equity compensation expense. These awards to directors vest 50% on the third anniversary and 50% on the fourth anniversary of the date of grant. Total equity compensation expense is recognized over the shorter of the vesting period or the period from the date of grant to the point of retirement eligibility. We recognized $225,000 and $110,000 of equity compensation expense in the third quarter of 2013 and 2012, respectively, related to these incentive compensation programs. For the first nine months of 2013 and 2012, we recognized equity compensation expense of $988,000 and $629,000, respectively.
