On behalf of the INS Board of Directors, I am pleased to submit INS' financial statement ending December 31, 2015.
Revenue was spread over 6 business segments and accounted for a total figure of $2 967 887. Total expenses were $2 953 721, leaving an operating income of $14 166.
From a count standpoint, membership remained flat in 2015, ending at 6387-9 more than the number at year end for 2014. We continue to see several trends in this business segment. They include an increasing number of clinicians who engage with us through means other than membership, including meeting attendance, the purchase of resources, Webinar participation, and the download of position papers. This type of engagement is important for INS, even if it does not translate into actual memberships. It brings increasing numbers of clinicians to our Web site and LEARNING CENTER who are seeking best-practice solutions. Another trend is the expansion of infusion therapy outside of the acute care setting into home care and alternative site settings. This market continues to increase, and more and more, companies in these care settings are seeking INS' help by providing membership and learning opportunities to their clinicians.
The Journal of Infusion Nursing continues to be regarded as INS' number 1 membership benefit. In addition to the expert clinical information it delivers, it also provides a significant amount of revenue through advertising, reprints, and licensing fees. These revenues, combined with those generated through sales of our educational resources, brought in $713 231 in revenue and a profit of $568 526 for the publications business segment.
The major driver of our revenue stream each year continues to be meetings, where revenue typically represents about 50% of INS' total revenue. Overall profit was $881 012, which represented 49% of our total revenues for 2015. There are many components that contribute to revenues in this category, but registrations, exhibit booth sales, and sponsorships top the list. On the expense side, travel, food and beverage, and expenses associated with the convention center make up a major portion of our expenses, which were $587 015. Total profit for this category was $881 012.
As a means of delivering educational programming to clinicians who are unable to attend our live programming, INS developed an online learning portal several years ago. Originally developed as the INS Knowledge Center, it was enhanced late in 2015 and rebranded the INS LEARNING CENTER. It currently holds more than 120 learning assets, and it has provided INS with another revenue stream through sponsorships and registration fees. Our bottom-line surplus for this category, infusion education services, was $33 131. We look for revenue to increase in this category as we add more learning modules and options to the LEARNING CENTER.
On the other side of the ledger are expenses, and general and administrative expenses account for a majority of them. The main components of general and administrative include payroll, rent, health insurance, and credit card fees. Each year we work diligently to keep tight control over all of our expenses. The past year was no exception. General and administration expenses increased by less than 1% from 2014.
An integral component of INS' mission is to support infusion certification each year through a certification support grant to INCC. Our contribution in 2015 was $144 000, as it was in 2014.
Finally, an independent accounting firm audited INS financial statements for the year ending December 31, 2015, in accordance with auditing standards. In its opinion, the financial statements present fairly, in all material respects, the financial position of INS.
