Boston-based Berkshire Income Realty Inc. has reported a nearly 34 percent increase in its funds from operations (FFO) to $6.4 million for 2010, compared to $4.8 million in 2009.

The increase in FFO is due primarily to expenses incurred in 2009 for which there were no recurring comparative expenses in 2010, according to a statement. The decrease in expenses was partially offset by $2.2 million of accrued incentive advisory management fee pursuant to the Advisory Services Agreement for which there was no comparable expense in 2009.
