Stock-Based Compensation Plans

All our employees and our non-employee directors are eligible for awards under the Morningstar 2011 Stock Incentive Plan, which provides for a variety of stock-based awards, including stock options, restricted stock units, performance share awards, market stock units, and restricted stock.

The following table summarizes the stock-based compensation expense included in each of our operating expense categories:

	Three months ended March 31,
(in millions)	2020		2019
Cost of revenue	$	2.4	$	3.1
Sales and marketing	1.0		1.4
General and administrative	3.9		5.5
Total stock-based compensation expense	$	7.3	$	10.0

As of March 31, 2020, the total unrecognized stock-based compensation cost related to outstanding restricted stock units, performance share awards, and market stock units expected to vest was $48.8 million, which we expect to recognize over a weighted average period of 26 months.
