Until January 1, 2013, the Federal Deposit Insurance Corporation (“<em>FDIC”</em>) provided unlimited coverage on non-interest-bearing accounts and insured all other bank accounts up to $250,000. After January 1, 2013, the unlimited coverage on non-interest-bearing accounts ceased and only accounts up to $250,000 are insured. Amounts in interest-bearing accounts in excess of $250,000, with the exception of amounts in FDIC sweep accounts, are at risk to the extent that their balances exceed FDIC coverage. Money market investments generally do not have FDIC protection. The average balance of our operating checking account balance is generally in excess of $250,000. We believe we have mitigated our exposure to loss by diversifying our deposits with different financial institutions. The only material exposure we have is with our operating account which is on deposit with one of the nation’s largest national banks.</div> <div style="clear:both;FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 0.5in; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"> </div> </div> </div> falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for cash and cash equivalent footnotes, which may include the types of deposits and money market instruments, applicable carrying amounts, restricted amounts and compensating balance arrangements. Cash and equivalents include: (1) currency on hand (2) demand deposits with banks or financial institutions (3) other kinds of accounts that have the general characteristics of demand deposits (4) short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments maturing within three months from the date of acquisition qualify.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Glossary Cash -URI http://asc.fasb.org/extlink&oid=6506951 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Glossary Cash Equivalents -URI http://asc.fasb.org/extlink&oid=6507016 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 1 -Article 5 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 210 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SX 210.5-02.1) -URI http://asc.fasb.org/extlink&oid=6877327&loc=d3e13212-122682 Reference 5: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 230 -SubTopic 10 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6367179&loc=d3e4273-108586 Reference 6: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 210 -SubTopic 10 -Section S99 -Paragraph 2 -Subparagraph (SAB TOPIC 6.H.3) -URI http://asc.fasb.org/extlink&oid=6877327&loc=d3e13728-122682 Reference 7: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Staff Accounting Bulletin (SAB) -Number Topic 6 -Section H -Subsection 3 false0CASH AND CASH EQUIVALENTSfalseCASH AND CASH EQUIVALENTSUnKnownUnKnownUnKnownUnKnowntruefalsefalseSheethttp://www.lphi.com/role/CashAndCashEquivalents12
