(2013) of unemployment funds, a worker must have been employed for at least one month and then be registered as a jobseeker in the public employment service agency and be at the disposal of the labour market. After one year of uninterrupted membership to an unemployment fund, and six months of half-time work, a worker is entitled to receive an earnings-related daily allowance of up to 80% of his or her regular income (with a maximum of 680 SEK per day) for the first 200 days. Regular income is the average income during the previous 12 months, including days of unemployment. After 200 days the rate decreases to 70% until the 300th day, and 70% from day 301-450 (only available for parents of children under the age of 18). After 300 (or 450) benefit days, anyone who is still unemployed can obtain a place in the Jobb-och utvecklingsgarantin (Job and development guarantee) labor market program. As declared by the Swedish Unemployment Insurance Bard (IAF) in 2006, 553,000 workers received benefits during the year, and the unemployment funds paid them 29.9 billion SEK, or an average 54,069 SEK per applicant. In fact, a form of intra-fund solidarity can be traced up; funds usually do not compete for members, as the trade unions usually refer to a "fund organizational area", and costs at this time were covered in solidarity by all the funds. This resulted in similar membership fees for every sector. Moreover, the funds’ costs were mainly paid by government grants. In 2006 only 9.4% of the unemployment benefits were financed by membership fees. Between 2006 and 2008, the share of workers affiliated with an unemployment fund decreased from 83% to 70%, attributable to hiked fund fees caused by decreased state-support. Fund fees returned to pre-2007 levels by 2014, when government funding was restored. In 2015, the density of unemployment funds was 71%, and union unemployment funds alone stood at 73%. Some unions also promote collective complementary insurance to better cover the growing quota of unemployed who receive less than 80% of their previous wages. Unions offer this benefit to counteract the stagnation of the maximum compensation level and the rise of unemployed average and high-earners. Unions also seek to supplement benefits where the insurance program falls short. In 2005, 45% of those receiving unemployment benefits received less than 80% of their previous income. The collective complementary insurances are fully financed
