AMN 2017 Annual Report

24 Compensation - Improvements to Employee Share-Based Payment Accounting” in the first quarter of 2017, which resulted in recording a $5.4 million reduction in income tax expense for the year ended December 31, 2017. Prior to the adoption, this amount would have been recorded as additional paid-in capital. This change could create future volatility in our effective tax rate depending upon the amount of exercise or vesting activity from our share-based awards. See additional information in “Item 8.

Revenue increased 30% to $1,902.2 million for 2016 from $1,463.1 million for 2015, due to additional revenue of approximately $194 million from our HSG, BES, Millican, TFS, OH and Peak acquisitions with the remainder of the increase driven by 17% organic growth. Nurse and allied solutions segment revenue increased 24% to $1,185.1 million for 2016 from $953.3 million for 2015. Of the $231.8 million increase, $45.7 million was attributable to the additional revenue in connection with the HSG acquisition and $2.0 million was attributable to the prior year having one less week of revenue from the OH acquisition as it was consummated on January 7, 2015 (the “OH Stub Period”), with the remainder primarily attributable to a 13% increase in the average number of healthcare professionals on assignment and a 6% increase in the average bill rate during the year ended December 31, 2016. Locum tenens solutions segment revenue increased 10% to $424.2 million for 2016 from $385.1 million for 2015. Of the $39.2 million increase, $0.6 million was attributable to the additional revenue of Locum Leaders over the OH Stub Period with the remainder primarily attributable to a 3% increase in the number of days filled and a 7% increase in the revenue per day filled during the year ended December 31, 2016. Other workforce solutions segment revenue increased 135% to $292.9 million for 2016 from $124.7 million for 2015. Of the $168.2 million increase, $145.5 million was attributable to the additional revenue in connection with the BES, Millican, TFS, and Peak acquisitions and the additional revenue of Medefis over the OH Stub Period, with the remainder primarily attributable to an increase in billable active searches and the average placement value in the physician permanent placement business as well as growth in our VMS and workforce optimization services revenue during the year ended December 31, 2016. Gross Profit. Gross profit increased 32% to $619.7 million for 2016 from $469.4 million for 2015, representing gross margins of 32.6% and 32.1%, respectively. The increase in consolidated gross margin was due to the growth in our higher margin other workforce solutions segment and higher bill-to-pay spreads in the locum tenens solutions segment, partially offset by higher direct costs in the nurse and allied solutions segment during the year ended December 31, 2016. Gross margin by reportable segment for 2016 and 2015 was 26.9% and 27.1% for nurse and allied solutions, 31.1% and 30.2% for locum tenens solutions, and 57.8% and 75.9% for other workforce solutions, respectively. The other workforce solutions segment decrease was primarily due to the change in the business mix resulting from the additions of BES, TFS and Peak during the year ended December 31, 2016. Selling, General and Administrative Expenses. SG&A expenses were $398.5 million, representing 20.9% of revenue, for 2016, as compared to $319.5 million, representing 21.8% of revenue, for 2015. The increase in SG&A expenses was primarily due to $35.1 million of additional SG&A expenses from the HSG, BES, Millican, TFS, and Peak acquisitions, and OH expenses over the OH Stub Period, as well as increased employee headcount, variable compensation, legal reserves, and other expenses associated with our revenue growth. SG&A expense increases as a result of acquisitions in the nurse and allied solutions, locum tenens solutions and other workforce solutions segments were $4.5 million, $0.1 million and $30.5 million, respectively. The increase in unallocated corporate overhead was primarily attributable to higher employee and variable expenses to support our growth, along with higher legal reserve costs. SG&A expenses broken down among the reportable segments, unallocated corporate overhead and share-based compensation are as follows: (In Thousands) Years Ended December 31, 2016 2015 Nurse and allied solutions $ 156,676 $ 134,570 Locum tenens solutions 73,126 68,096 Other workforce solutions 91,936 54,327 Unallocated corporate overhead 65,335 52,254 Share-based compensation 11,399 10,284 $ 398,472 $ 319,531
