On June 30, 2014, we completed a recapitalization of FNF common stock into two tracking stocks, FNF Group common stock and FNFV Group common stock. Each share of the previously outstanding FNF Class A common stock ("Old FNF common stock") was converted into one share of FNF Group common stock and 0.3333 of a share of FNFV Group common stock.
While projected increases in mortgage interest rates present a potential headwind for mortgage originations, other economic indicators used to measure the health of the United States economy, including the unemployment rate and consumer confidence, have improved in recent years. According to the United States Department of Labor's Bureau of Labor, the unemployment rate has dropped from 7.4% in 2013 to 4.1% in December 2017. Additionally, the Conference Board's monthly Consumer Confidence Index rose sharply at the end of 2016 and has remained at historical highs through 2017. We believe that improvements in both of these economic indicators, among other indicators which support a generally improving United States economy, present potential tailwinds for mortgage originations and support recent home price trends.
Because commercial real estate transactions tend to be generally driven by supply and demand for commercial space and occupancy rates in a particular area rather than by interest rate fluctuations, we believe that our commercial real estate title insurance business is less dependent on the industry cycles discussed above than our residential real estate title business. Commercial real estate transaction volume is also often linked to the availability of financing. For several years through 2015, we experienced continual year-over-year increases in the fee per file of commercial transactions. In 2016, we experienced a slight decrease in the volume and fee per file of commercial transactions as compared to 2015, but commercial markets still remained at historically elevated levels. Through 2017, we have continued to see strong demand for commercial transactions and have experienced historically high fees per file.
On September 29, 2017 we completed our tax-free distribution, to FNF Group shareholders of all 83.3 million shares of New BKH Corp. ("New BKH") common stock that we previously owned (the “BK Distribution”). Immediately following the BK Distribution, New BKH and Black Knight Financial Services, Inc. ("Black Knight") engaged in a series of transactions resulting in the formation of a new publicly-traded holding company, Black Knight, Inc. ("New Black Knight"). Holders of FNF Group common stock received approximately 0.30663 shares of New Black Knight common stock for every one share of FNF Group common stock held at the close of business on September 20, 2017, the record date for the BK Distribution. New Black Knight's common stock is now listed under the symbol “BKI” on the New York Stock Exchange. The BK Distribution is expected to generally be tax-free to FNF Group shareholders for U.S. federal income tax purposes, except to the extent of any cash received in lieu of New Black Knight's fractional shares. As a result of the BK Distribution, we have reclassified the assets and liabilities divested as assets and liabilities of discontinued operations in our Consolidated Balance Sheet as of December 31, 2016. Further, the financial results of Black Knight have been reclassified to discontinued operations for all periods presented in our Consolidated Statements of Earnings. See Note G. Discontinued Operations for further details of the results of Black Knight.

As a result of the FNFV Split-Off we have reclassified the assets and liabilities divested as assets and liabilities of discontinued operations in our Consolidated Balance Sheet as of December 31, 2016.
