MNTA - Question about tax assets. Per the last 10k MNTA claimed about 250M of operating loss carryforward and total deferred tax assets of $115M (including $92M of state and federal net operating losses).

Simple question - how many quarters of, say, $65M per quarter of operating income (before taxes) before they use up their tax assets? (I assume it is just ($250-$32M (Net income this q))/$65M= about 3.5 more quarters before it is used up.

PS I assume that the deferred tax asset is just the carryforward losses adjusted by expected tax rate plus a few miscellaneous credits etc?
