Key Metrics In addition to the U. S.  GAAP and non-GAAP metrics discussed elsewhere in this Form 10-K, we also monitor the following metrics to evaluate our business, measure our performance and identify trends affecting our business:
## Table 1 ##
?
Clients.
When we calculate the number of clients at period end, we treat client accounts with separate taxpayer identification numbers as separate clients, which often separates client accounts that are affiliated with the same parent organization.
We track the number of our clients to provide an accurate gauge of the size of our business.
Unless we state otherwise or the context otherwise requires, references to clients throughout this Form 10-K refer to this metric.  ?
Clients (based on parent company grouping).
When we calculate the number of clients based on parent company grouping at period end, we combine client accounts that have identified the same person(s) as their decision-maker regardless of whether the client accounts have separate taxpayer identification numbers, which often combines client accounts that are affiliated with the same parent organization.
We track the number of our clients based on parent company grouping to provide an alternate measure of the size of our business and clients.  ?
Sales Teams.
We monitor our sales professionals by the number of sales teams at period end.
Each team consists of a sales manager and approximately six to eight sales professionals.
Certain larger metropolitan areas can support more than one sales team.
We believe that the number of sales teams is an indicator of potential revenues for future periods.  ?
Annual Revenue Retention Rate.
Our annual revenue retention rate tracks the percentage of revenues that we retain from our existing clients.
We monitor this metric because it is an indicator of client satisfaction and revenues for future periods.
Components of Results of Operations Sources of Revenues Revenues are comprised of recurring revenues, and implementation and other revenues.
We expect our revenues to increase as we introduce new applications, expand our client base and renew and expand relationships with existing clients.
As a percentage of total revenues, we expect our mix of recurring revenues, and implementation and other revenues to remain relatively constant.
Recurring.
Recurring revenues include fees for our talent acquisition, time and labor management, payroll, talent management and HR management applications as well as fees charged for form filings and delivery of client payroll checks and reports.
These revenues are derived from (i) fixed amounts charged per billing period plus a fee per employee or transaction processed or (ii) fixed amounts charged per billing period.
We do not require clients to enter into long-term contractual commitments with us.
Our billing period varies by client based on when they pay their employees, which is done either weekly, bi-weekly, semi-monthly or monthly.
Because recurring revenues are based, in part, on fees for use of our applications and the delivery of checks and reports that are levied on a per-employee basis, our recurring revenues increase as our clients hire more employees.
Recurring revenues are recognized in the period services are rendered.
Beginning April 1, 2016, recurring revenues also include interest earned on funds held for clients.
We collect funds from clients in advance of either
Cash flows from financing activities for the year ended December 31, 2016 changed by $80.6 million due to the impact of changes in client funds obligation, which is due to the timing of receipts from our clients and payments to our clients’ employees.
Financing cash flows were also impacted by the $5.0 million increase in proceeds from the issuance of long-term debt and a $0.2 million decrease in principal payments on long-term debt.
These cash flows provided by financing activities were partially offset by the $35.6 million increase in open market purchases of common stock and $14.4 million increase in withholding taxes paid related to net share settlements.
Contractual Obligations Our principal commitments primarily consist of long-term debt and leases for office space.
We disclose our long-term debt in Note 5 and our commitments and contingencies in Note 12 to our audited consolidated financial statements included elsewhere in this Form 10-K.  As of December 31, 2017, the future non-cancelable minimum payments under these commitments were as follows:
## Table 2 ##
We may continue to lease additional office space to support our growth.
In addition, many of our existing lease agreements provide us with the option to renew.
Our future operating lease obligations include payments due during any renewal period provided for in the lease where the lease imposes a penalty for failure to renew.
The contractual commitment amounts in the table above are associated with agreements that are enforceable and legally binding and that specify all significant terms, including fixed or minimum services to be used, fixed minimum or variable price provisions, and the approximate timing of the transaction.
Obligations under contracts that we can cancel without a significant penalty are not included in the table above.
Off-Balance Sheet Arrangements As of December 31, 2017, we did not have any off-balance sheet arrangements that have or are reasonably likely to have an effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that may be material to investors.
Critical Accounting Policies and Estimates Our consolidated financial statements and accompanying notes have been prepared in accordance with U. S.  GAAP.
The preparation of these consolidated financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses, and related disclosures.
On an ongoing basis, we continually evaluate our estimates and assumptions believed to be reasonable under current facts and circumstances.
Actual amounts and results may materially differ from these estimates made by management under different assumptions and conditions.
